Top 10 Foods for Reversing Type 2 Diabetes

The following foods are nutrient-dense powerhouses that contains a diverse array of phytonutrients, macronutrients and micronutrients that provide superior nutritional benefits and multiple health benefits for people with Type 2 diabetes.

As a result, these foods can help a Type 2 diabetic to better manage and control his/her diabetes; and, possibly, reverse their diabetes and prevent the onset of major complications such as amputation and blindness.

When eaten on a regular basis (primarily in their raw form), these foods provide health benefits in the form of vitamins, minerals, antioxidants, polyphenols, fiber, and healthy fats. Each of these foods offer more nutritional value per serving than most other foods. In addition, most of these foods are inexpensive and readily available in most grocery stores and health food stores. 

These foods provide key nutrients to the heart, brain, liver, kidneys, blood, and other key organs throughout the body. As a result, these foods help to prevent and fight many of the top diseases and illnesses, including diabetes, heart disease, cancer, obesity, high blood pressure, high cholesterol, high blood sugar, and chronic fatigue.

Note: This "Top 10" list of foods has grown, based on new research and clinical findings.

Almonds and Walnuts
Almonds have been around since Biblical times, and are a staple in the heart-healthy Mediterranean diet. Almonds are rich in vitamin E and contain heart-healthy monounsaturated fats which helps to lower the risk of heart disease. Healthy fats like the ones in almonds help lower LDL cholesterol if they replace saturated or trans fats in the diet.

Almonds: SuperfoodA quarter-cup of almonds also contains more protein than an egg. They’re also packed with magnesium, which helps boost production of the brain chemical dopamine — good for regulating mood and preventing depression.

In addition, almonds also contain fiber, riboflavin, and calcium. And, because of its fiber content, almonds, along with other high-fiber foods, may play a role in improving stomach problems, like irritable bowel disorders and diarrhea, and boosting calcium absorption.

The American Heart Association recommends eating a handful of nuts as one serving at least four times per week.

Researchers at Loma Linda University found that adding two 1-ounce servings of almonds daily to study participants’ diets helped them to achieve a better intake of key nutrients and helped them to lower their intake of dietary detractors like trans fats, excessive sodium, sugars and cholesterol. Eating nuts may help protect against heart disease and inflammation, and research on walnuts showed that enjoying as little as eight to 11 walnuts daily reduced total cholesterol by up to 4 percent.

Note: Just be sure you avoid making the mistake of consuming nuts that are heated commercially as the fats they contain are perishable and will be damaged when they go through this type of processing. A new 21st century concern is pasteurization.  For the last four years, nearly all commercial vendors of almonds are required to pasteurize them before sale.

Where to get them: Anywhere nuts are sold. If they don’t have it in your local market, Trader Joe’s has a wide selection. Many farmer’s markets feature a nut seller, who will be happy to answer your questions about the nutritional value of almonds, as well as offer samples.

Added bonus: Whether you’re craving salty or sweet, almonds make the perfect snack food. The roasted nuts come in a variety of flavors, like wasabi, BBQ, vanilla or cinnamon. Or, if you’re feeling adventurous, swap out your peanut butter for almond butter. Mild and versatile, these nuts work well in sweet and savory dishes.

Walnuts: SuperfoodWalnuts happen to be high in omega-3s, which research indicates can reduce the risk of heart disease, diabetes, cancer, high blood pressure and even depression. A daily handful of walnuts — which contains about 200 calories — is literally a generous handful of health.
Walnuts: Superfood

Eat walnuts as a snack or incorporate them into your favorite recipes — adding chopped walnuts to any dish will lend a delectable crunch and nutty flavor.

Walnuts are packed with tryptophan, an amino acid your body needs to create the feel-great chemical serotonin. (In fact, Spanish researchers found that walnut eaters have higher levels of this natural mood-regulator.) They're digested slowly, which contributes to mood stability and can help you tolerate stress.

If you use walnuts as a pre-walk snack or add them to your favorite oatmeal cookie recipe, you may enjoy even greater cholesterol-lowering benefit. Walnuts are a rich source of heart-healthy omega-3 fatty acids, as well as a compound called ellagic acid that has been shown to reduce artery-forming plaque. Nuts are a truly heart healthy snack, topping or addition to any meal.

Note: Nearly all raw nuts are healthy for us due to their heart-healthy unsaturated fats and other phytonutrients.

Artichokes
Artichokes: SuperfoodIf you've been huffing and puffing up the stairs, try these spiky-leafed vegetables.

They're loaded with magnesium, a mineral vital for more than 300 biochemical reactions in the body—including generating energy, says Forrest Nielsen, PhD, a U.S. Department of Agriculture research nutritionist. "If you're not getting enough magnesium, your muscles have to work harder to react and you tire more quickly."

About 68% of us aren't getting enough of this mineral. For women, the goal is 320 milligrams (mg) per day. One medium artichoke provides 77 mg of magnesium (and just 60 calories!). Other top sources include nuts, legumes, and whole grains.

Asparagus
Asparagus: SuperfoodThese spears are one of the best veggie sources of folate, a B vitamin that could help keep you out of a slump. "Folate is important for the synthesis of the neurotransmitters dopamine, serotonin, and norepinephrine," says David Mischoulon, MD, a psychiatrist at Harvard Medical School. All of these are crucial for mood.

A cup of cooked asparagus has 268 micrograms (mcg)—two-thirds of the 400 mcg RDA for women. Add a cup of enriched pasta—which is fortified with folic acid, the synthetic form of folate—and you'll have a feel-good meal indeed.

Avocado
Avocado: SuperfoodAvocados are high in healthy monounsaturated fat and have a rich source of glutathione – a powerful antioxidant known to block over 30 different carcinogens (a substance capable of causing cancer in living tissue).

Avocados are also one of the most nutrient-dense foods; high in fiber, potassium, vitamin E, and magnesium.

Also, if you’re looking to banish wrinkles then stock up as they are packed with antioxidants and good fats, which help in your fight against the frown.

Avocados are an excellent source of healthful raw fat, which most Americans are seriously deficient in. They also provide close to 20 essential health-boosting nutrients, including: Fiber, Potassium (more than twice the amount found in a banana), Vitamin E, B-vitamins, and Folic acid
             
In addition, avocados enable your body to more efficiently absorb fat-soluble nutrients, such as alpha- and beta-carotene and lutein, in other foods eaten in conjunction.

Black Beans and Other Beans
Beans hit it out of the ballpark when it comes to nutrition. They’re loaded with the essential minerals, folate, magnesium and iron. Beans are the only food that crosses two categories on the food pyramid, Bazilian says. They’re both a complex carbohydrate and a protein source.

Beans: SuperfoodAll types of beans (kidney, chickpeas, soybeans, dried peas and lentils) are low in fat and have anti-ageing properties but these small red beans have one of the highest antioxidant ratings. Typically used in Japanese cooking adzuki beans are a good source of carbohydrates, folate, potassium, phosphorus, magnesium, iron, manganese and zinc.

Beans are a fabulous source of vegetarian protein and fiber, two nutrients that help you stay full and satisfied. The protein and fiber in beans also tempers the rise in blood sugar that occurs after a meal, which can help stabilize mood. The fiber in beans also helps keep you regular (every half cup serving adds another 7 g of fiber to you daily total) Beans are low in fat and a good source of magnesium and potassium, nutrients that work together to lower blood pressure and keep your heart and blood vessels healthy.

However, beans are not a perfect protein because they lack some essential amino acids. However, adding an organic whole grain (such as quinoa or amaranth) fixes this problem, especially for vegans.


Added bean bonus: They're inexpensive! So stock up on canned, no-salt added varieties and add them to soups, salads, stews, and more!

People who regularly consume beans have better weight management and blood sugar regulation because of their soluble fiber. Black beans, in particular, have three times the amount of omega-3 fats than other beans, and their dark skin contains cancer-fighting chemicals called flavonoids.

A cup of black beans packs 15 grams of protein, with none of the artery-clogging saturated fat found in meat. Plus, they're full of heart-healthy fiber, antioxidants, and energy-boosting iron. 

Note: If you’re wary of the fiber content, you can avoid digestive distress by easing beans into your diet slowly. Eat no more than half a cup at a time.

Where to get them: Canned beans are, by far, the most convenient – and they’re relatively cheap at 80 cents a can. But with a little planning, dried beans can save you even more money and aren’t too labor-intensive. Simply cover dried beans with water in a large bowl, let sit overnight with a bay leaf or two, drain, and voila! Your fresh beans are ready to cook.

Tip: Use half beans and half turkey to make chili, or adding beans to lean ground beef for sloppy Joes.

Blueberries and Other Berries
Blueberries are considered to be a nutrient-rich food. Eating blueberries will provide you with antioxidants, phytonutrients and fiber. According to the MayoClinic.com, eating blueberries will help you age in a healthy way and prevent chronic diseases. Blueberries, which are low in calories, can be easily snacked on, added to cereals, and baked into breads and sweets.

Blueberries: SuperfoodDid you know that much of the power of blueberries lies in their color? That deep-blue hue is a by-product of flavonoids — natural compounds that protect the brain's memory-carrying cells (neurons) from the damaging effects of oxidation and inflammation. Since blueberries are one of the best sources of flavonoids you can find, it's no surprise that this food has been shown to help preserve memory function.

Blueberries, like other berries, also have a high water content, which makes them hydrating for your skin and other cells of the body.

Açai Berries: This exotic berry from Amazon was named by nutritionist Nicholas Perricone as one of the greatest foods in the world. They are packed full of antioxidants which can help combat premature aging and contain something called monounsaturated oleic acid, which helps omega-3 fish oils penetrate the cell membrane. There’s also amino acids and essential fatty acids, to help promote cardiovascular and digestive health.

Goji Berries: Also known as wolfberries, this Himalayan fruit contains all 18 amino acids (six times higher than bee pollen) as well as huge amounts of vitamin A, B1, B2, B6 and vitamin E. Gram for gram they are packed with more iron than steak and spinach, and more beta carotene and vitamin C than carrots and oranges, respectively.

Strawberries: They may not have the smoothest complexion themselves, but strawberries can get you one. They're loaded with antioxidants that help your skin repair damage caused by environmental factors like pollution and UV rays. Plus, they're packed with vitamin C (less than a cup gets you your entire 75 mg RDA)—the vitamin associated with fewer wrinkles and less dryness, per research in the American Journal of Clinical Nutrition.
                                                 
Broccoli
Low in calories (about 30 calories per cup) and high in health-promoting polyphenols, broccoli is considered one of the most potent nutrient-dense foods. Broccoli is rich in fiber, folate, phytonutrients, vitamin C and vitamin A. Regularly eating broccoli can help prevent heart disease, diabetes, cell damage, worsening eye sight and some forms of cancer. These berries are full of phytonutrients that neutralize free radicals (agents that cause aging and cell damage). The antioxidants in these berries may also protect against cancer and reduce the effects of age-related conditions such as Alzheimer's disease or dementia.

Broccoli: SuperfoodPacked with folic acid, vitamin C and carotenoids (the colourful plant pigments some of which the body can turn into vitamin A), broccoli is thought to boost your immune system, protect your cells from being damaged by free radicals and improve reproductive health. Broccoli also contains beta carotene, energy producing vitamins B3 and B5, potassium and chromium , which help regulate blood sugar and cholesterol levels.

Cruciferous vegetables contain indole alkaloids that may suppress the growth of tumors and help prevent cancer. They are also high in fiber, antioxidants, vitamins and minerals. Plus, foods from the cruciferous and cabbage family (including broccoli, cabbage, kale, cauliflower, Brussels sprouts, collards and turnips) may help bolster memory as you age. Researchers at Harvard Medical School found that women who eat the most of these foods are the least likely to be forgetful.

Cruciferous veggies like broccoli, cauliflower and Brussels sprouts pack a serious punch against cancer.
That’s one reason why Joel Fuhrman, M.D., author of Eat for Health (Gift of Health Press) and Eat to Live (Little, Brown and Company), recommends eating foods from that family every day.

In lab studies, sulforaphane, a chemical found in broccoli and its cousins, actually made cancer cells like leukemia and melanoma self-destruct. A 2007 Chinese study found that the compound may slow down the spread of breast cancer.

Where to get it: Frozen or fresh, broccoli is easy to come by year-round. To get the most out of this vegetable, try to eat it raw or lightly steamed — cooking kills off most of its vitamin C.

Broccoli can be easily eaten raw as a snack, added to stir fries, pasta dishes and fajitas, or it can be steamed and eaten as a side dish with meals. The fiber in broccoli will help you remain full longer and keep your energy levels high.

Studies have shown that broccoli can combat cancer and heart disease, ward off cataracts, boost the immune system and reduce the risk of birth defects. Broccoli can be eaten raw, lightly steamed or stir-fried — be sure to cook until just crisp tender to avoid dampening broccoli's nutritional power. Include chopped broccoli in grain dishes, salads or as part of omelets or quiche.

Note: If you don't like broccoli, try cauliflower instead.                                                                                

Eggs (Organic)
Eggs received a bad rap because of the phobia tied to high cholesterol. But, the egg is an amazing source of high-quality nutrients that many people are deficient in, especially high-quality protein and fat.

Eggs: SuperfoodA single egg contains: 9 essential amino acids, high quality protein, lutein and zeaxanthin (for your eyes); choline for your brain, nervous and cardiovascular systems; and naturally occurring  B12.

Proteins are nutrients that are essential to the building, maintenance and repair of your body tissues such as your skin, internal organs and muscles. They are also the major components of your immune system and hormones

Note: Ideally, you'll want to eat the whole egg, especially the yolk where most of the key nutrients reside. If possible, eat your eggs raw, or as close to raw as possible, such as soft-boiled or poached.

Note: If you choose to use egg whites, please don't eat them raw unless you also consume the egg yolks, otherwise you risk developing a biotin deficiency.

Flaxseed
Flaxseed, also known as linseed, is one of the ancient cultivated crops since Mesopotamian times, grown for its oil seeds, and fiber. The chewy seeds are packed with full of nutrients, omega-3 fatty acids, antioxidants, minerals, and essential vitamins.

Flaxseed: SuperfoodFlaseed is an excellent source of vitamin E, especially rich in gamma-tocopherol; containing about 20 g (133% of daily-recommended values) per 100 g. vitamin E is a powerful lipid soluble antioxidant, required for maintaining the integrity of cell membrane of mucus membranes and skin by protecting it from harmful oxygen-free radicals.

The seeds are packed with many important B-complex groups of vitamins such as riboflavin, niacin, thiamin, pantothenic acid, vitamin B-6, and folates. Thiamin is an essential co-factor for carbohydrate metabolism and helps prevent beri-beri disease. Folates help prevent neural tube defects in the fetus when consumed during pre-conception period and pregnancy.

Furthermore, flax seed is rich source of minerals like manganese, potassium, calcium, iron, magnesium, zinc and selenium.

Flaxseed delivers the full benefits of Omega-3 EFA (alpha linolenic acid), the Omega-6 and Omega-9 EFAs, plus all of the fiber, protein, lignans, vitamins, minerals and amino acids, to help control blood glucose levels, appetite, and cravings.

Lignans are a type of natural plant chemical contained within the cell matrix of the flaxseed that act as plant hormones. When bacteria in the digestive tract act on plant lignans, these compounds are converted into potent, hormone-like substances, known as phytoestrogens. Research findings have concluded that the chemical release of these phytoestrogens is able to block the action of certain cancer-causing substances associated with breast, colon and prostate cancers.

Researchers believe these plant hormones mimic the body’s own estrogen type of cells and can block the formation of hormone-based tumors or growths. Unlike the hormones produced in the body, these plant hormones do not stimulate cancerous cells to grow. In fact, lignans boost production of a substance that fastens onto human estrogen and carries it out of the body. Lignans are also considered to be antioxidants; therefore, researchers believe they can protect healthy cells from free radical oxidative damage.
                             
Garlic
Garlic tops the National Cancer Institute’s list as a potential cancer-preventive food.

It is a powerful antioxidant and anti-inflammatory food that protects against heart disease, reduces blood pressure and lowers cholesterol levels. It also has vitamins C and B6, manganese, and selenium.

Olive Oil (Extra Virgin)
Anyone familiar with the Mediterranean diet is aware of the nutrient power of extra virgin olive oil and its health benefits, as well as the wonderful flavor of a good dose of olive oil on salads, fish, pasta and almost anything else.

Statistics have shown that Mediterranean populations such as Spain, Italy & Greece, have significantly lower rates of coronary heart disease (CHD) than that seen throughout the rest of the world. 

Extra Virgin Olive Oil: SuperfoodThe quality of olive oil production - especially the stage of pressing - really does make a difference when it comes to health benefits. Recent studies have compared the anti-inflammatory benefits of extra virgin olive oil (EVOO) obtained from the first pressing of the oil to the anti-inflammatory benefits of virgin olive oils (non-EVOO) obtained from later pressings.

Health benefits of extra virgin olive oil include the following:

A reduction in inflammation markers was identified by researchers that EVOO  lowered the inflammatory markers in the blood when non-EVOOs were unable to do so. (Study measurements included blood levels of thromboxane A2, or TXA2, and leukotriene B2, or LBT2.)

This ability of extra virgin olive oil to help protect against unwanted inflammation is not surprising, since EVOO is known to contain stronger concentrations of phytonutrients (especially polyphenols) that have well-known anti-inflammatory properties. 

Research has documented a wide variety of anti-inflammatory mechanisms used by olive oil polyphenols to lower our risk of inflammatory problems. These mechanisms include decreased production of messaging molecules that would otherwise increase inflammation (including TNF-alpha, interleukin 1-beta, thromboxane B2, and leukotriene B4); inhibition of pro-inflammatory enzymes like cyclo-oxygenase 1 and cyclo-oxygenase 2; and decreased synthesis of the enzyme inducible nitric oxide synthase.

In heart patients, olive oil and its polyphenols have also been determined to lower blood levels of C-reactive protein (CRP), a widely used blood measurement for assessing the likelihood of unwanted inflammation. They have also been found to reduce activity in a metabolic pathway called the arachidonic acid pathway, which is central for mobilizing inflammatory processes.

Heart disease reduction has been identified in numerous studies of the Mediterranean Diet that olive oil intake contributed to a decreased risk of heart disease. However, a recent group of studies has provided us with a fascinating explanation of olive oil's cardioprotective effect. One of the key polyphenols in olive oil - hydroxytyrosol (HT) - helps protect the cells that line our blood vessels from being damaged by overly reactive oxygen molecules.

Recent research studies have taken these heart-healthy effects of olive oil one step further. Olive oil's monounsaturated fat content (specifically, its high level of oleic acid) has now been determined to be a mechanism linking olive oil intake to decreased blood pressure. Researchers believe that the plentiful amount of oleic acid in olive oil gets absorbed into the body, finds its way into cell membranes, changes signaling patterns at a cell membrane level (specifically, altering G-protein associated cascades) and thereby lowers blood pressure.

To our knowledge, this is the first time that the monounsaturated fat content of olive oil has been linked not only to cholesterol reduction, but also to reduction of blood pressure.

Anti-clotting benefits have been demonstrated by various laboratory studies have also found that 2-(3,4-di-hydroxyphenyl)-ethanol (DHPE), a phenol component of extra-virgin olive oil with potent antioxidant properties, is able to inhibit platelet aggregation (blood clotting) more effectively that other flavonoids. The phenol enriched portion of olive oil also demonstrated similar activity. 
 
This is important because heart attacks and strokes are caused by blood clots which build up in the arteries of the heart or brain which have been narrowed due to atherosclerotic plaque formation. The ability to form normal blood clots to physical trauma is of course necessary to prevent hemorrhage (uncontrolled bleeding), however the degree of blood clot inhibition which would occur due to olive oil consumption would not be so severe that it would be dangerous at all.

Cancer prevention has been one of the most active areas of olive oil research, and the jury is no longer out on the health benefits of olive oil with respect to cancer. Twenty-five studies on olive oil intake and cancer risk - including most of the large-scale human studies conducted up through the year 2010 - have recently been analyzed by a team of researchers at the Mario Negri Institute for Pharmacological Research Institute in Milan, Italy.

Firmly established by this research team were the risk-reducing effects of olive oil intake with respect to cancers of the breast, respiratory tract, upper digestive tract and, to a lesser extent, lower digestive tract (colorectal cancers). These anti-cancer benefits of olive oil became most evident when the diets of routine olive oil users were compared with the diets of individuals who seldom used olive oil and instead consumed diets high in saturated added fat, especially butter.

Digestive health benefits of olive oil for the digestive tract were first uncovered in research on diet and cancers of the digestive tract. Numerous studies found lower rates of digestive tract cancers - especially cancers of the upper digestive tract, including the stomach and small intestine - in populations that regularly consumed olive oil.  

Recent research has provided us with even more information, however, about olive oil, its polyphenols, and protection of the digestive tract. One fascinating area of recent research has involved the polyphenols in olive oil and the balance of bacteria in our digestive tract. Numerous polyphenols in olive oil have been shown to slow the growth of unwanted bacteria, including bacteria commonly responsible for digestive tract infections.

Improved cognitive function - especially among older adults - is a well-known feature of the Mediterranean Diet. As the staple oil in that diet, olive oil has been of special interest for researchers interested in diet and cognitive function. In France, a recent study large-scale study on older adults has shown that visual memory and verbal fluency can be improved with what the researchers called "intensive use" of olive oil. In this case, "intensive use" meant regular use of olive oil not just for cooking, or as an ingredient in sauces and dressings, but in all of these circumstances.

Note: When you savor the peppery zing of extra-virgin olive oil, you’re tasting powerful antioxidants. The phytonutrients that bring the bite also have an anti-inflammatory effect on your body. That helps protect and repair the cardiovascular system, which constant fluctuations in blood sugar can damage. Olive oil is also incredibly versatile. It's appropriate for anything from salads to sautés. Best of all, it slows absorption of the carbohydrates it's paired with for a healthier glycemic load overall.

Raw Vegetable Juice
Raw vegetable juice provides key vitamins, minerals, antioxidants, enzymes, and other phytonutrients that help to prevent and reverse various diseases, especially heart disease, cancer,  Type 2 diabetes, and obesity. 
Raw Vegetable Juice: Superfood

 Scientist says that when you drink juice, the nutrients enter your bloodstream within 30 minutes, so you get the healthy benefits from fresh vegetables almost immediately.

Also, raw vegetable juice is easy on your digestive tract because the juicer removes the fiber, making it easier for your body to assimilate the nutrients from the raw vegetable juice. The enzymes in raw juice increases metabolism, so you will feel energized. Also, when your metabolism is higher, it’s easier to drop those unwanted pounds.
Raw Green Vegetable Juice: Superfood

Since raw vegetable juice contains chlorophyll, this helps to strengthen your body through cellular cleansing. Chlorophyll assists the liver with detoxifying, it rebuilds blood cells, removes parasites and exotoxins, eliminates mold, and assists your body in preventing and eliminating cancer cells. It also assists your body by helping to stabilize your blood glucose level.

Note: For more information about raw juice, refer to the Death to Diabetes website or the Power of Raw Juicing ebook.

Note: Since bottled vegetable juices at health food stores are pasteurized,  these bottled juices provide very little if any health benefits.

Sardines
Sardines get a bad rap. But before you toss this one back to sea, know this: These guys taste like tuna, are less fishy than caviar and come already de-headed – so they won’t stare back when you peel open a can.

Why it's a good food for women: Sardines are a cheap and convenient way to fill up on fish oil, vitamin D and calcium all at once, says Janis Jibrin, M.S., R.D., co-author of The Best Life Guide to Managing Diabetes and Pre-Diabetes (Simon & Schuster).

"Just one can of bone-in sardines covers 125% of your vitamin D needs, 35% of your calcium and 88% of your daily selenium requirement,” she says.

Selenium, an antioxidant, helps keep the immune system fighting fit and protects our cells from damage.

Where to get it: For the healthiest catch, choose water-packed sardines without added salt. - See more at: http://www.lifescript.com/health/centers/cancer/articles/10_foods_women_should_eat.aspx#sthash.5DeKwAxl.dpuf
Sardines get a bad rap. But, they provide many health benefits to the heart and the brain. Sardines and other small, fatty fish are high in essential omega-3 fatty acids that our bodies can only get from the food we eat.
Sardines: Superfood

As a result, sardines and other omega-3-rich fish help in a couple of ways: They're a great source of fat and protein to slow absorption of blood sugars, and they help protect your cardiovascular system, which irregular blood sugar fluctuations that can come with diabetes can damage.

The healthy fat in sardines is good for your brain, too, and may help fend off Alzheimer's disease and dementia. Also, sardines contain selenium, an antioxidant which helps keep the immune system fighting fit and protects our cells from damage.

Why it's a good food for women: Sardines are a cheap and convenient way to fill up on fish oil, vitamin D and calcium all at once. Just one can of bone-in sardines covers 125% of your vitamin D needs, 35% of your calcium and 88% of your daily selenium requirement.

Where to get it: For the healthiest catch, choose water-packed sardines without added salt.

Seaweed
There are many types of seaweed, which has been used traditionally in Asian diets. Seaweed is low in calories, but high in nutrients. According to the Planet Green website, seaweed provides a number of benefits such as alkalizing your blood, promoting weight loss, deterring the formation of cellulite and providing protection from different environmental toxins.

Seaweed is commonly used in sushi, but it can also be used as a baked snack, as a seasoning, and as an added vegetable in soups and stir fries.

Spinach
Spinach: SuperfoodSpinach is filled with antioxidants, including vitamin C and beta-carotene, as well as lutein and zeaxanthin — a duo that acts like sunscreen for your eyes and guards against macular degeneration.

One cup of fresh spinach leaves also provides almost double the daily requirement for vitamin K, which plays an important role in cardiovascular and bone health.

And of course you can't forget that spinach is a great vegetarian source of iron, which keeps your hair and nails strong and healthy. Use fresh spinach leaves as a base for salad or sauté it and add to an omelet.

Researchers in Sweden recently identified another way in which these greens might keep you charged: Compounds found in spinach actually increase the efficiency of our mitochondria, the energy-producing factories inside our cells. That means eating a cup of cooked spinach a day may give you more lasting power on the elliptical machine (or in your daily sprint to catch the bus).                                         

Wild Salmon
Salmon contain a rich supply of omega-3 fats which contribute to overall health by protecting against heart disease and some cancers. Additionally, omega-3 fats fight inflammatory conditions and depression. Wild Alaskan salmon is noted to be the best variety for its nutritional benefits.
Wild Salmon: Superfood

Salmon contains omega-3 fatty acids, which the body cannot produce by itself. These fatty acids reduce inflammation, improve circulation, increase the ratio of good to bad cholesterol, and may slash cancer risk. Salmon is a rich source of selenium, which helps prevent cell damage, and several B vitamins.

Wild Alaskan salmon is the best wild salmon, as long as its purity can be verified. Wild Alaskan salmon  is an excellent source of: Essential animal-based omega-3 fats (EPA and DHA), Astaxanthin and other antioxidants, and High-quality protein.

Oily fish (such as salmon, trout, mackerel, herring, sardines, pilchards, kippers and fresh tuna (not canned))  is important because it’s rich in omega 3 fatty acids, which are especially useful in warding off heart disease. Most oily fish contains protein, zinc, selenium, vitamins A and D, and some B vitamins. Omega 3-rich seafood might help slow down macular degeneration (a common cause of age-related blindness), protect against the build up of cholesterol on the artery walls which can cause heart damage, and help reduce the impact of arthritis.

Bonus: There's wrinkle prevention on your plate: "Salmon is rich in a fatty acid called eicosapentaenoic acid (EPA), a type of omega-3 that naturally helps block the release of UV-induced enzymes that diminish collagen, causing lines and sagging skin," says Ariel Ostad, MD, a dermatologist in New York City. Omega-3s also regulate oil production in the skin and boost hydration, which helps keep your complexion dewy and acne-free.

Also, the fish's omega-3 fatty acids could help you fight flab more effectively. They alter the expression of certain genes, shifting your body to burn fat rather than store it.

Proof: In a study analyzing the diets of 35,000 women, published in Public Health Nutrition, those subjects who ate oily fish such as salmon two to four times per week had the lowest basal metabolic indexes, a common measure of body fat.
                                          
Yogurt (Organic)
Eating yogurt (or kefir) made from grass-fed raw milk is an excellent way to boost your immunity and increase your daily energy. Lowfat and nonfat Greek and regular yogurts contain 20 percent or more of your daily calcium needs. The mineral slows production of cortisol, a hormone that encourages belly-flab buildup.
Yogurt: Superfood

Kefir is a traditionally fermented food that is chockfull of healthful bacteria (probiotics). In ancient times, food preservation was accomplished through lacto-fermentation, a process that adds a host of beneficial micro-organisms to food. This makes them easier to digest, and increases the healthy flora in your intestinal tract.

The importance of maintaining healthy balanced gut flora simply cannot be overstated. Far from simply helping your body to better digest and assimilate your food (which they do very well), probiotics influence the activity of hundreds of your genes, helping them to express in a positive, disease-fighting manner.

Friendly bacteria also train your immune system to distinguish between pathogens and non-harmful antigens, and to respond appropriately. This important function prevents your immune system from overreacting to non-harmful antigens, which is the genesis of allergies.

Probiotics can even help to normalize your weight, and lack of beneficial bacteria in your gut may play a significant role in the development of type 2 diabetes, depression and other mood disorders, and may even contribute to autism and vaccine-induced damage.

Note: Please beware that pasteurized products will not provide you with these health benefits, as the pasteurization process destroys most of the precious enzymes and other nutrients.
                                                 
Other Healthy Foods

Here are some other foods that contain key phytonutrients that provide multiple health benefits.

Apples
This fruit's 4 to 5 grams of fiber not only are filling but also help ferry out some of the fat and calories you take in from other foods.

The  proof: People who ate an apple 15 minutes before lunching on cheese tortellini consumed 187 fewer calories in total than those who snacked on nothing beforehand, a study from Penn State University in University Park determines. How about them apples?

Beets
Don’t let the color scare you: These crimson root vegetables are sweet, rich and buttery. And the nutritional value these red devils pack is so great, you should get to know them better.

Why it's a good food for women: A 2008 American Heart Association study reported that beet (otherwise known as beetroot) juice helps in bringing blood pressure down.

Even if you don’t feel like you’re at risk for high blood pressure, you will be. One in three Americans has hypertension and 90% will get it in their lifetime. High blood pressure can damage your arteries, which can lead to plaque buildup, heart disease, blood clots and strokes.

According to Jonny Bowden, Ph.D., author of The 150 Healthiest Foods on Earth (Fair Winds Press), beets are loaded with potassium, which counteract the effects of our salt-heavy diet. They’re also high in folate, which we need to manufacture new cells and prevent DNA damage (a precursor to cancer).

Beet juice may also boost workout stamina by 16%, making exercise feel less tiring so you can go for longer, according to a 2009 English study.

The chemicals in beets also show great promise in combating cancer and inflammation.

Bell Peppers
A little known fact: one red bell pepper has twice as much vitamin C as an orange. Vitamin C is a powerful antioxidant that helps clear your body of free radicals and keeps your skin and blood vessels healthy and strong. The vitamin C in bell peppers may also help prevent arthritis or slow the progression of the disease. Red bell peppers also deliver beta-carotene and lycopene, two more antioxidants that have been associated with decreased risk of eye diseases like cataracts. And, thanks to their high water content, bell peppers of all colors are a high-volume, low-cal food that's very figure-friendly. 

Cherries (Tart )
Don’t confuse tart cherries with the sweet black cherries usually found in the supermarket produce aisle. This fruit is most often used in baking and comes frozen, canned or as juice.

Why it's a good food for women: Tart cherries are anti-inflammatory and may be great for managing pain.

“They’ve long been used to treat arthritis and gout symptoms,” says Bazilian. Research in animals and humans suggests they can help relieve arthritis and post-workout muscle soreness, lower cholesterol and possibly even reduce body fat, according to a 2009 University of Michigan study.

Where to get it: Your cheapest bet: Buy them canned, for about $2.50 each, in the baking aisle. Tart cherries have the same zippy flavor as cranberries and taste good in smoothies or mixed with other fruits. 

Chia SeedsChia Seeds
High in protein and loaded with fiber and omega-3 fatty acids, chia seeds are a nutritional powerhouse. The flour made from these nutty-tasting seeds is a great addition to a diabetes-friendly kitchen. “It actually lowers blood sugar due to the fiber and omega-3 fatty acid content,” says Amy Jamieson-Petonic, RD, spokesperson for the Academy of Nutrition and Dietetics, and director of coaching at Cleveland Clinic. 

There's some evidence that chia seeds help reduce belly fat -- the kind that contributes to insulin resistance. Substitute a quarter of your regular flour with chia flour (and experiment with higher ratios) in just about any baked good. Order the flour online, find it at health-food stores, or grind chia seeds in a food processor.

Cinnamon Cinnamon
The bark of Cinnamomum trees contains phytochemicals that enhance insulin signaling and facilitate glucose uptake and storage by the body’s cells. Studies have shown that as little as a teaspoon of cinnamon a day may significantly decrease fasting blood glucose levels and increase insulin sensitivity. There are lots of ways to add more cinnamon to your diet. Sprinkle some in your tea, stir it into your morning oatmeal, or add it to rubs for chicken or fish.

Note: The two major types of cinnamon used in food preparation are Ceylon cinnamon and Cassia cinnamon. Ceylon cinnamon (Cinnamomum verum or Cinnamomum zeylanicum), native to Sri Lanka, is also known as “true cinnamon.” This is NOT the predominant spice typically sold as cinnamon in the United States. What is commonly found at your grocer is a closely related and less expensive variety called Cassia cinnamon. Cassia is native to Burma and also grown in China and Vietnam. Cassia is slightly darker in color compared to Ceylon, and has a stronger, more pungent flavor. While both Cassia and Ceylon are derived from the inner bark of Cinnamomum trees, Ceylon cinnamon is preferable. Ceylon cinnamon is considered a finer quality spice due to its sweeter, more delicate and complex flavor.

In addition to flavor, a critical difference between Ceylon and Cassia is the coumarin content of Cassia. Cassia cinnamon is the main source of coumarin in the human diet. Coumarin is a naturally occurring toxin which has the potential to damage the liver in high doses. Cassia contains high levels of coumarin, whereas Ceylon contains either undetectable levels or only traces of coumarin. Coumarin can cause liver toxicity in several species, and was found to be carcinogenic in rodents.

Citrus Fruit
Citrus fruit such as grapefruit, oranges, lemons and limes provide soluble fiber and vitamin C. The white part right underneath the skin contains hesperdin, a flavanone glycoside that fights cancer. Specifically, the limonoid compounds in limes have been shown to prevent cancers of the colon, stomach and blood. Though the exact mechanism is unknown, scientists have observed that antioxidant limonoids also cause cancer cell death. Lime limonoids also stay active longer in your bloodstream, mopping more free radicals than green tea or dark chocolate.

Note: Citric acid is a natural inhibitor of kidney stones made of crystallized calcium. Go for fresh lime juice squeezed into water, as opposed to commercial limeades, for maximal benefits.

Coconut Oil (Organic)
Half of the fat content in coconut oil is lauric acid—a fat rarely found in nature—that could easily qualify as a "miracle" ingredient because of its unique health promoting properties. Your body converts lauric acid into monolaurin, which has anti-viral, anti-bacterial and anti-protozoa properties.

Additionally, the naturally occurring saturated fat found in coconut oil also has some amazing health benefits, such as: Promoting heart health, Supporting immune system health, Providing you with an immediate energy source, Promoting weight loss, Supporting a healthy metabolism , andSupporting the proper functioning of your thyroid gland

Your body sends medium-chain fatty acids directly to your liver to use as energy. This makes coconut oil a powerful source of instant energy to your body, a function usually served in the diet by simple carbohydrates.  Additionally, research has demonstrated that, due to its metabolic effect, coconut oil also increases the activity of your thyroid. And you've probably heard that a sluggish thyroid is one reason why some people are unable to lose weight, no matter what they do…

Perhaps one of the most interesting benefits of coconut oil is its potential to ward off, or perhaps even treat, dementia. According to research by Dr. Mary Newport, ketone bodies—an alternative fuel for your brain which your body makes when digesting coconut oil—may offer profound benefits in the fight against Alzheimer's disease.

Coconut oil is the ideal choice for all types of cooking. In fact, it's the only oil stable enough to resist mild heat-induced damage. So, whenever you need an oil to cook or bake with, use coconut oil instead of butter, olive oil, vegetable oil, margarine, or any other type of oil called for in recipes. And, if you must fry, by all means use coconut oil -- it's your smartest choice.

Dark Chocolate
Believe it or not, chocolate is a healthy treat, as long as you choose wisely. Dark chocolate is rich in flavonoids, antioxidants that have been shown to lower blood pressure, improve blood flow, and boost overall heart health. Choose chocolate that is at least 70 percent cacao or cocoa to optimize the antioxidant power and health benefits.

Dark chocolate may even boost your mood. While there's no scientific explanation for why, the rich taste and sensuous mouth-feel of a decadent piece of dark chocolate may be to thank. Just be sure to keep your portions in check — one ounce of dark chocolate has about 150 calories.

Very high on the happiness quotient, which alone is thought to add years to your life. Also contains flavonols, which are potent antioxidants.

Grapes (Dark Purple, Red)
Grapes provide vitamin C, vitamin B1 and vitamin B6, but mostly provide pleasure in their juiciness and sweetness. Red and purple grapes also contain powerful phytochemicals (especially phenolics) that may help decrease risk of cardiovascular disease. These phenolic compounds are housed mostly in the skin of the red grapes.

Resveratrol, a polyphenolic stilbene found in the skins of red and purple fruits including grapes, may be responsible for some of the health benefits ascribed to the consumption of red wine. Resveratrol has been shown to have anti-oxidant, anticancer, and anti-inflammatory activity.

Enjoy grapes in salads, alone as a snack, or sliced in sandwiches.

Tip for your children: Place a bunch of grapes in the freezer. Your kids can eat the frozen grapes like a popsicle while receiving its health benefits.

Green Tea
Green teaGreen tea contains polyphenols, which may reduce heart disease, cancer and stroke risk. Green tea also supports brain health and memory, likely due a key compound in green tea called EGCG (epigallocatechin gallate), a flavonoid. EGCG is thought to boost the immune system and prevent tumors. Aim for at least two cups daily.

Green tea — as well as black, white and red teas — is high in polyphenols and the flavonoid EGCG. Studies suggest that drinking tea every day can fight cancer, stroke and heart disease as well as boost the immune system and cognitive health. Replace your daily soft drinks with calorie-free tea and take advantage of the many green tea infused drinks and food products.

Hummus
Hummus
Hummus, a Middle Eastern specialty, is a great addition to a diabetes-friendly plate. The fiber and protein in chickpeas -- 12 grams of dietary fiber and 15 grams of protein per cup -- help regulate the absorption of the sugars from the starch so your blood sugar stays on an even keel.

The healthy fats from the tahini (made from ground sesame seeds) and olive oil slows the absorption of sugars even more. Pair your hummus with vegetables and whole-grain crackers for an even greater effect.

Kale
Kale's dark green pigment is an indicator of its concentrated supply of beneficial compounds. Lutein and zeaxanthin both protect against cataracts, while abundant vitamin A and other carotinoids work as powerful antioxidants. Kale is a rich source of vitamin K, which benefits cardiovascular health and helps to keep bones strong.

Kale contains a type of phytonutrient that appears to lessen the occurrence of a wide variety of cancers, including breast and ovarian. Though scientists are still studying why this happens, they believe the phytonutrients in kale trigger the liver to produce enzymes that neutralize potentially cancer-causing substances. 

Not only does it do a number on cancer, it also helps the heart. According to Jibrin, a half-cup of kale juice per day jacked up helpful HDL cholesterol by 27% and lowered artery-clogging LDL in just 12 weeks.

Kale is loaded with vitamin C, which is great for your complexion, along with calcium and vitamin A, Bazilian says. Leafy greens also contain nutrients — carotenoids such as lutein and zeaxanthin – that help preserve vision and prevent eyestrain, a serious asset for those who stare at a computer screen all day.

Lentils
Lentils are smart legumes when managing your blood sugar. They contain a good amount of starch (normally a no-no when managing blood sugar), which gives them a satisfying, hearty creaminess. Lentils are also packed with both soluble and insoluble dietary fiber. Soluble fiber turns into a gel-like consistency during digestion, which slows absorption of the sugar molecules in the starch. Insoluble fiber passes through the digestive tract without "registering" as a carbohydrate, while slowing down the whole digestive process so you stay satisfied and your blood sugar remains steady.

Nuts
Nuts of all sorts -- walnuts, pecans, take your choice! -- are great for controlling blood sugar. Despite their diminutive size, nuts are power packages of protein, unsaturated (healthy) fat, and fiber. Those three factors have a positive impact on blood sugar levels. In a recent study, participants who ate 2 1/2 ounces of nuts daily had an 8% decrease in their A1c levels. Keep in mind that nuts also pack plenty of calories. Your best bet is to substitute nuts for high-carbohydrate foods, such as croutons or pretzels. Sprinkle them on yogurt and salads, or nibble them for a snack.

Pomegranate
Once considered an exotic fruit, the beautiful ruby red pomegranate is bursting with antioxidants and delicious sweet-tart flavor (at only about 100 calories each). Excellent for heart and brain health, pomegranate arils (seeds) can be tossed in salads, sprinkled on yogurt or ice cream, folded into muffin or pancake batter, used as a colorful garnish or simply snacked on as is. Pomegranate juice can be enjoyed as a refreshing wake-me-up, turned into a sweet syrup, or transformed into a tasty trendy cocktail. 

Pumpkin
Pumpkin is good for a lot more than carving jack-o'-lanterns on Halloween — it's loaded with nutrients that will help your heart, bones, eyes, and skin. Beta-carotene and potassium are the two standouts here: Beta-carotene is an antioxidant that helps rejuvenate skin, protect your vision, and may even reduce risk of arthritis. Potassium is a mineral involved in lowering blood pressure and maintaining healthy bones. Use fresh or canned (no-sugar-added) pumpkin in stews, soups, pies, or pureed as a side dish — or add a scoop to some nonfat vanilla yogurt for a yummy snack.

Quinoa
Quinoa (pronounced ‘Keen-wah’) is a protein-rich seed that the Incas ate to give them strength and energy. It is gluten-free, high in amino acids, protein, vitamin B6, B1, B2, B3, and potassium. Plus it is a great source of copper, zinc, iron, magnesium, and folate.

Quinoa is a excellent grain for many reasons: It’s one of the few non-animal proteins that's considered a "complete protein" in that it has all of the essential amino acids your body needs to build protein molecules. Plus, quinoa is a whole grain with germ, endosperm, and bran intact, bringing a host of nutrients and healthy fat to the mix. Quinoa is also a source of calcium, so useful for vegans and those who are lactose intolerant. 

Even better, all those benefits come with very little impact on your blood sugar level. A half-cup of cooked quinoa ranks just under 10 (that's low!) on the glycemic load scale. It's easy to add quinoa to meals. Try using it in place of white rice as a side.

Why it's a good food for women: Quinoa contains all nine of the essential amino acids. The building blocks of protein, amino acids make up our muscles, tendons, glands and organs. Since our body can’t manufacture or store them, we need a steady source from our diet.

Without even one of the essential nine, our muscles and organs would start to break down. Most of us get all that we need from meat, but vegetarians need a surplus of whole grains and legumes to keep their levels intact.

Unlike refined carbohydrates, which are stripped of nutrients and fiber during processing, organic whole grains are loaded with antioxidants, vitamins and minerals. Quinoa is a good source of magnesium, which helps relax blood vessels and maintain healthy blood pressure levels. It may even be help prevent migraines.

Note: Other organic whole grains that provide major health benefits  include amaranth and bulgur. Amaranth seeds are between 14 and 16 percent protein, packed with the amino acid lysine, are gluten-free, and have about 8 grams of fiber per cooked cup. Bulgur is a type of cracked wheat kernel packed with a lot of fiber per cup (about 8 grams) and close to 6 grams of protein.

Sweet Potatoes
Sweet potatoes are good for your health, but not so much if they are baked into high calorie and high fat dishes. Eating sweet potatoes by themselves will provide you with carotenoids, vitamin C, potassium and fiber. Sweet potatoes are relatively fat free and very low in calories.

Sweet potatoes can provide a healthy alternative to sweets and desserts because of their natural sweetness. If you must add sugar to your sweet potato dish, use apple sauce, raisins or pieces of apples.

Tomatoes
Tomatoes contain lycopene, an antioxidant rarely found in other foods. Studies suggest that it could protect the skin against harmful UV rays, prevent certain cancers, and lower cholesterol. Plus, tomatoes contain high amounts of potassium, fiber, and vitamin C. Tomato

Lycopene is a powerful antioxidant that gives tomatoes their red color and it helps absorb the damaging free radicals that can harm our cells.

Tomatoes are packed full of vitamins including vitamins A, C and E and contain potassium and other mineral salts. Not only does their high water content make them refreshing, but they’re low in calories too. It is thought tomatoes help ward against prostate breast cancers and stomach cancers as well as age-related macular degeneration.

Leafy Vegetables
Spinach, kale, chard, and other leafy greens are loaded with vitamins, such as folate; minerals, such as magnesium; a range of phytonutrients; and insoluble fiber -- all of which have virtually no impact on your blood sugar level. Mark Hyman, MD, author of The Blood Sugar Solution (Little, Brown and Company), calls leafy greens "free foods," which means you should eat as many of them as you can. Bonus: The fiber in leafy greens will slow absorption of any carbohydrates (e.g., potatoes or bread) they’re paired with, resulting in a healthier overall glycemic load.
Leafy Vegetables: Superfood

This vegetable group includes salad greens, spinach, collards, kale, radicchio, and watercress.  Leafy vegetables may grow in tight loose heads or individually on stems.  A few leafy greens, such as turnip greens and beet greens, are actually the tops of root vegetables.

Salad greens, such as lettuce, are usually served raw.  Sturdier more flavorful greens, such as kale and collard greens, are usually served cooked.  They can also be eaten raw. 

Most leafy vegetables are rich in carotenoids (such as beta carotene), vitamin C, and are good sources of fiber and folate.  They also provide varying amounts of chlorophyll, iron, and calcium.

Other Foods to Eat
Other foods that help to prevent diabetes, heart disease, obesity, and high blood pressure include vegetables such as broccoli, Brussels sprouts, bok choi, kale, Romaine lettuce; asparagus, cabbage, cauliflower, celery, cucumbers, okra, peppers, stringbeans, other greens (collard, turnip); sea vegetables such as chlorella and sea plankton; and, grasses such as wheat, barley, alfalfa.

Vegetables of other bright colors (green, red, yellow, purple, orange) include artichokes, avocado, bean sprouts, beets, carrots, chickpeas, mushrooms, onions, parsley, peppers, pumpkins, sweet potatoes, tomatoes, and zucchini. 

Fruits include dark, bright-colored fruits such as açai berries, blackberries, blueberries, cherries, cranberries, elderberries, strawberries, apples, grapes, goji berries; apricots, avocado, figs, grapefruits, kiwi, lemons, limes, mangosteens, melons, papaya, peaches, pears, plums, pomegranates, prunes, raspberries.

Lean protein includes fish (wild salmon, sardines, tuna, mackerel, tilapia), nuts, seeds, beans, lentils, whey protein, whole soy foods (tofu, tempeh, miso, soy protein powder); lean, organic beef, chicken breast without the skin, turkey breast without the skin; goat’s milk, low fat plain yogurt; organic eggs, egg whites; low fat cheese, soy/tofu cheeses, blue-green algae (spirulina, chlorella); grains (amaranth, quinoa); wild game (venison, bear); organic seafood (shrimp, crab, lobster); and vegetables.

Nutritional Science Overview

Nutritional science is the study of the effects of food components and its molecules on the metabolism, health, performance and disease resistance of humans and animals. Nutritional science studies how the body breaks food down (catabolism) and repairs and creates cells and tissue (anabolism) -- catabolism and anabolism = metabolism.

Nutritional science interprets the interaction of nutrients and other substances in food (e.g. macronutrients, minerals, phytonutrients, anthocyanins, tannins, etc.) in relation to maintenance, growth, reproduction, health and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism and excretion.

Nutritional science focuses on how diseases, conditions and problems can be prevented or lessened with a healthy diet. In addition, nutritional science involves identifying how certain diseases, conditions or problems may be caused by dietary factors, such as poor diet (malnutrition), food allergies, metabolic diseases, etc.

And, as molecular biology, biochemistry and cell biology advance, nutritional science has become more focused on the steps of biochemical and biological sequences through which substances inside us and other living organisms are transformed from one form to another via metabolism and metabolic pathways.

The diet of an organism is what it eats, which is largely determined by the availability, processing and palatability of foods. A healthy diet includes preparation of food, meal planning and storage methods that preserve nutrients from oxidation, heat or leaching, and that reduce risk of food-born illnesses.

A poor diet may have an injurious impact on health, causing deficiency diseases such as scurvy; health-threatening conditions like celiac disease, obesity and metabolic syndrome; and such common chronic systemic diseases as cardiovascular disease, diabetes, and osteoporosis.

Similarly, a good diet may have a positive impact on health, causing an improvement in one's health and improving one's ability to live a life of wellness.

Note: Nutritional science also incorporates the elements of social science to explore the connection between diets, food choices, habits, lifestyle, finances and health.

Macronutrients and Micronutrients
The human body requires six major types of nutrients -- 4 macronutrients and 2 micronutrients -- where a nutrient is a source of nourishment, a specific molecule or component within a food.

Macronutrients are nutrients we need in relatively large quantities. Micronutrients are nutrients we need in relatively small quantities.

Macronutrients
There are four (4) key macronutrients:
-- Carbohydrates
-- Proteins
-- Fat
-- Water

The building blocks of carbohydrates are saccharides such as glucose. The building blocks of proteins are amino acids such as lysine. And, the building blocks of fats are fatty acids such as linoleic acid.

Carbohydrates
Carbohydrates are the most abundant biological molecules, and are an important nutritional component of many foods.

Carbohydrates consist of glucose molecules of carbon, hydrogen and oxygen atoms. Carbohydrates include monosaccharides (glucose, fructose, galactose), disaccharides, oligosaccharides, and polysaccharides (starch).

Carbohydrates are classified according to size. The smallest carbohydrates are called monosaccharides ( mono means "one"; saccharide means "sugar"). The largest carbohydrates are called polysaccharides ( poly, means "many").

As the name implies, monosaccharides are single sugar molecules. The most common monosaccharides, such as fructose and glucose, have six carbon atoms, but monosaccharides can have as few as three or as many as seven.

Monosaccharides with five or more carbons usually have a ring-shaped structure when they are in a solution.

Oligosaccharides ( oligo means "few") are more complex carbohydrates composed of chains of two or a few (up to about twenty) simple sugars joined with a type of covalent bond called a glycosidic bond.

Polysaccharides ( poly, means "many") are important energy-storage and structural molecules. They are formed of long chains of sugars, most commonly glucose.

Carbohydrates serve many purposes, from producing energy to structure to chemical communication.

Carbohydrates are at the center of cellular metabolic pathways. The most fundamental process, glycolysis , uses glucose to produce energy for cellular needs.

There are 4 major dietary types of carbohydrates:
-- Sugar
-- Starch
-- Non-starch
-- Fiber

There are 4 major carbohydrate chemical groups:
-- Monosaccharides
-- Disaccharides
-- Oligosaccharides
-- Polysaccharides

Key food sources for carbohydrates include: vegetables, fruits, whole grains, cereals, breads, baked goods, starches, pastries, sweets, soft drinks, juices, and foods made with flour and sugar.

Proteins
Proteins are chains of amino acids that fold into a three-dimensional shape. Proteins consist of molecules that contain nitrogen, carbon, hydrogen and oxygen. Simple proteins, called monomers, are used to create complicated proteins, called polymers, which build and repair tissue.

Proteins are probably the most important class of material in the body. Proteins are not just building blocks for muscles, connective tissues, skin, and other structures.

Proteins are also needed to make enzymes. Enzymes are complex proteins that control and carry out nearly all chemical processes and reactions within the body. The body produces thousands of different enzymes.

Thus, the entire structure and function of the body is governed by the types and amounts of proteins the body synthesizes. Protein synthesis is controlled by genes, which are contained on DNA molecules called chromosomes.

Proteins (including their lipoprotein and glycoprotein forms) constitute 10 percent of the weight of the blood plasma of living organisms, carrying various nutrients throughout the body and acting as signals to coordinate bodily functions between the different organs.

The amino acids of a protein are connected to each other by peptide bonds. Each amino acid has several common features: an amino and a carboxyl chemical group both bonded to the alpha carbon (Cα) and an R group that defines a particular amino acid.

Types of Dietary Proteins
From a nutritional perspective, the key types of proteins are: plant, animal and dairy.

Proteins are made up of building blocks called amino acids. There are 20 different amino acids that join together to make all types of protein. 

The (9) essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

The (11) non-essential amino acids are arginine, cysteine, glycine, glutamine, proline and tyrosine; alanine, aspartic acid, asparagine, glutamic acid and serine.

A complete protein source is one that provides all of the essential amino acids. Animal-based foods such as meat, poultry, fish, milk, eggs, and cheese are considered complete protein sources.

An incomplete protein source is one that is low in one or more of the essential amino acids.

Complementary proteins are two or more incomplete protein sources that together provide adequate amounts of all the essential amino acids.

Key food sources for proteins include: vegetables; eggs; nuts and seeds; legumes (dry beans and peas); soy (tofu, tempeh, miso); blue-green algae (spirulina); dairy (milk, cheese); animal meats, poultry, fish; and, whole grains.

Types of Functional Proteins
From a cell biological perspective, the key types of proteins include: hormonal, enzymatic, structural, storage, transport, receptor, and contractile.

These proteins support the function, growth and maintenance of all our cells and body tissues.

Structural: Also known as fibrous proteins, these are the largest class of proteins that include collagen, keratin and elastin. These protein types serve as essential components to your body's construction. Keratin and collagen are the most common structural proteins.  Collagen forms the connective framework of your tendons, bones, muscles, cartilage and skin. Keratin is the main structural component in your skin, nails, hair and teeth.

Hormonal: Hormonal proteins act as chemical messengers secreted by the cells of the endocrine glands. Usually transported through the blood, hormones act as chemical messengers that transmit signals from one cell to another. Each hormone affects certain cells in your body, known as target cells.

Enzymatic: Enzymes serve as biological catalysts needed for chemical reactions, including liver functions, stomach digestion, blood clotting and converting glycogen to glucose.

An example is digestive enzymes that break down complex food molecules into simpler forms that your body can easily absorb. Amylolytic digestive enzymes reduce carbohydrates and starches to glucose and proteolytic enzymes reduce proteins to amino acids.

Defensive: Antibodies, or immunoglobulins, are a core part of your immune system, that protects your body from pathogens and other foreign substances, keeping diseases at bay. Antibodies are formed in the white blood cells and attack bacteria, viruses and other harmful microorganisms, rendering them inactive.

Storage: Storage proteins house critical elements that your cells need. Hemoglobin is a vital protein that stores oxygen in your red blood cells. This critical protein is transported to all of your cells and tissues as your blood circulates. Ferritin is a storage protein that houses the crucial element iron, which is required for the formation of hemoglobin, the main structural component of red blood cells.

Transport: Transport proteins carry vital materials to the cells. Hemoglobin, for example, carries oxygen to body tissues from the lungs. Serum albumin carries fats in your bloodstream, while myoglobin absorbs oxygen from hemoglobin and then releases it to the muscles. Calbindin is another transport protein that facilitates the absorption of calcium from the intestinal walls.

Receptor: Located on the outer part of the cells, receptor proteins control the substances that enter and leave the cells, including water and nutrients. Some receptors activate enzymes, while others stimulate endocrine glands to secrete epinephrine and insulin to regulate blood sugar levels.

Contractile: Also known as motor proteins, contractile proteins regulate the strength and speed of heart and muscle contractions. These proteins are actin and myosin. Contractile proteins can cause heart complications if they produce severe contractions.

Fats and Lipids
Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, monoglycerides, diglycerides, triglycerides, phospholipids, and others.

Lipids contain molecules that consist of carbon, hydrogen, and oxygen atoms. Fats are triglycerides - three molecules of fatty acid combined with a molecule of the alcohol glycerol. Fatty acids are simple compounds (monomers) while triglycerides are complex molecules (polymers).

The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.

Lipids play vital roles in many cellular processes including energy storage, vitamin storage, structural cell membrane support, protection, communications, the functioning of nerve cells and acting as raw materials that can be converted to other substances that perform special duties in the body such as hormones.

There are four biologically important lipids:
-- Fats (or dietary fats)
-- Phospholipids (for cell membranes)
-- Steroids (such as cholesterol)
-- Waxes (for protection)

Fats are large molecules composed of three fatty acid molecules bonded to a glycerol molecule (and configured as triglycerides) 

There are 4 major types of fats: saturated, monounsaturated, polyunsaturated and trans fat.

Note: Although the term lipid is sometimes used as a synonym for fats, as you can see, fats are a subgroup of lipids.

Phospholipids are similar to fats except they have two fatty acid chains bonded to a glycerol molecule and phosphoric acid, with the fatty acid component being saturated or unsaturated.

Phospholipids are unique because they have a hydrophobic (water-insoluble) and a hydrophilic (water-soluble) end.

Phospholipids are biologically important because they are the main structural components of cell membranes. But, the cell membrane incorporates other lipids, such as cholesterol, that contribute to its structural integrity; and, glycolipids, which help with cellular communications.

As a result, there are three common types of membrane lipids: phospholipids, glycolipids, and cholesterol [Structural Biochemistry].

Steroids are structurally different from the other lipids. The carbon skeleton of steroids is bent to form four fused rings that do not contain fatty acids. The most common steroid, cholesterol, is an important component of cell membranes that helps to provide cell structure and integrity.

Cholesterol is important for nerve cells. The molecule binds to the myelin sheath which provides an outer coating that protects the nerve cell. Also, cholesterol is needed to make both the male (testosterone) and female (estrogen) sex hormones. So, you see, cholesterol is not as bad as you thought. :-)

Another popular steroid group is the anabolic steroids that are man-made and mimic the effect of the male hormone, testosterone. Athletes have recently been using these steroids to increase muscle mass, stamina, and strength. Certain beneficial fat-soluble hormones, such as cortisol, are also familiar steroids.

Waxes are similar to fats except that waxes are composed of only one long-chain fatty acid bonded to a long-chain alcohol group attached. Both plants and animals use the waterproofing characteristic of waxes. For example, plants most noticeably use waxes for a thin protective covering of stems and leaves to prevent water loss.

Types of Dietary Fats
There are four major types of fats or fatty acids, based on how many of their carbon bonds are paired with hydrogen:
-- Saturated
-- Monounsaturated
-- Polyunsaturated
-- Trans-unsaturated

Saturated fats are fully loaded with hydrogen atoms forming straight chains. More specifically, saturated fats have single bonds between all the carbon atoms, and therefore all the carbons are bonded to the maximum number of hydrogen atoms.

These chains are fairly straight and can pack closely together, making these fats solid at room temperature.

Examples of saturated fats: butter, coconut oil.

Unsaturated fats have some double bonds between some of the carbons in the tail, causing the molecule to bend. As carbon atoms with double bonds are not bonded to as many hydrogens as possible, they are called unsaturated fats. The kinks in the tails mean that unsaturated fats can't pack as closely together, making them liquid at room temperature.

Monounsaturated fatty acids (MUFAs) are unsaturated fatty acids that are missing one pair of hydrogens -- they have one double bond in the fatty acid chain with all of the remainder carbon atoms being single-bonded.

Examples of monounsaturated fats: olive oil, avocado.

Polyunsaturated fatty acids (PUFAs) are unsaturated fatty acids that are missing more than one pair of hydrogens -- they have more than one double bond.

Examples of polyunsaturated fats: vegetable oil (corn oil), Omega-3 (fish), Omega-6 (evening primrose oil).

Trans-unsaturated fatty acids (trans fats, for short) are a man-made unsaturated fat that is more linear and rigid, where hydrogen atoms are added via a process called hydrogenation causing double bonds to become single ones.

Partial hydrogenation results in the addition of hydrogen atoms at some of the empty positions, with a corresponding reduction in the number of double bonds.

Examples of trans fats: margarine, fried food, French fries, packaged foods.

Micronutrients
There are two (2) key micronutrients:
-- Vitamins
-- Minerals

Vitamins are organic molecules in our food that are essential nutrients for good health.

Minerals are inorganic chemical elements required by living organisms, other than the four elements carbon, hydrogen, nitrogen, and oxygen that are present in nearly all organic molecules.

Vitamins
Vitamins are organic compounds in food that are required for normal cell function, growth, and development.

There are probably hundreds of these organic compounds in the food, but, as of today, we have discovered 13 essential vitamins.

These vitamins fall into 2 categories: fat-soluble and water-soluble.

Fat-Soluble Vitamins: Fat-soluble vitamins are those that bind to fat in the stomach and are then stored in the body for later use. We are less likely to become deficient in these vitamins (A, D, E, and K), but more likely to build up to toxic levels, usually due to extreme over-consumption or overzealous supplement use.

Water-Soluble Vitamins: The rest of the vitamins are water-soluble, meaning they can be absorbed directly by cells. The water-soluble vitamins (Vitamin B-Complex, Vitamin C), niacin, folic acid, pantothenic acid, and the four B complex vitamins — need to be restored more frequently, but the body can tolerate higher doses. When taken in excess, these vitamins are flushed out of our system with each bathroom break.

Minerals
Dietary minerals are the other chemical elements our bodies need, apart from carbon, hydrogen, oxygen and nitrogen.

Six minerals are required by people in gram amounts: sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), phosphorus (P), and chlorine (Cl). Daily requirements range from 0.3 to 2.0 grams per day.

Nine trace minerals (microminerals) are required by people in minute amounts: chromium (Cr), copper (Cu), iodine (I), iron (Fe), fluorine (F), manganese (Mn), molybdenum (Mo), selenium (Se), and zinc (Zn).

Note: The term "minerals" is misleading, and would be more relevant if called "ions" or "dietary ions".

Author's Sidebar:
Have you noticed that there’s an abundance of nutrition experts with dietary systems and approaches that are vastly different –  and yet they lack scientific substance and validation? And, more importantly, these systems don't appear to work in the long run when fighting a disease like Type 2 diabetes.
 
So ,now that we understand the key components of nutrition, we need to better understand the following:
-- Which are the best carbohydrates, proteins and fats for us to eat?
-- How do these macronutrients help us to prevent and fight disease?
-- How do we design and plan our meals on a daily basis?

These questions are answered in other blog posts; and, in the Death to Diabetes book, DTD science ebook and DTD training program.

Metabolism of Carbs, Proteins and Fats
The body must be able to metabolize or break down the macronutrients in order to eventually produce energy for your body.

When you eat food, the body digests and breaks down the carbohydrates into glucose, the proteins into amino acids, and the fats into fatty acids.

The glucose causes your blood sugar level to rise, triggering the release of insulin. This enables your cells to absorb the glucose; and, along with oxygen, your cells produce chemical energy, called adenosine triphosphate (ATP). 

ATP is then made available to other parts of the cell so that the cell can do its job and perform all of its functions.

Proteins and Fats can be broken down and used as energy sources, but, it takes more work.

How Cells Obtain Energy from Food
Cells require a constant supply of energy to generate and maintain the biological order that keeps them alive. This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells.
Sugars are particularly important fuel molecules, and they are oxidized in small steps to produce energy (ATP), carbon dioxide (CO2), water and heat.

The 3 major stages that transform food into energy are three main sets of reactions that act in :
1. Glycolysis (which occurs in the cytosol)
2. Krebs cycle (in the mitochondrial matrix)
3. Electron Transport Chain (on the inner mitochondrial membrane)

Nutritional Science Concerns
Let’s take a big picture look at the field of nutritional science:

It’s the wild wild west – everyone’s an expert! There’s a new diet every week!

It’s still a young science – meaning nutrition is still developing, and we still don’t truly understand the depth of this science.

Experts disagree – and it’s okay as long as you understand the science behind the differences.

There's too much selling on the Internet. A lot of times, it’s “marketing” trying to sell something instead of helping people with their health issues.

No field in Science operates with universal agreement – that’s just the way it is. You need to build up your tolerance for disagreement and understand it.

Scientists can be very passionate, very religious, and very dogmatic. Scientists are just like you and me – they’re human beings. So, don’t strictly rely on them – educate yourself by reading multiple authors and science studies.

Nutrition is not respected by most medical doctors; and, that has become a major problem because people are noticing that taking drugs for most health problems isn’t working.

As a result, more and more people are looking at Alternative Medicine, especially those aspects of Alternative Medicine that are focused on nutrition.

Nutrition is not infallible – a lot of mistakes have been made over the years. Today’s nutrition facts are often tomorrow’s fallacies.

For example, we used to think margarine was good for us. We thought butter was bad. We thought all saturated fat was bad. We thought that low fat diets were good for us. We thought that it was okay to put artificial colors in food. We thought that all protein was the same, and all fat was the same. We thought grain was good for everyone.

So, what do you do? How do you prevent yourself from becoming a victim of another mistake? The best thing to do is to educate yourself at the lowest level possible; and, read/learn from multiple sources.

Humans are still growing and evolving – and so is our nutrition. So it makes perfect sense that we continue to educate ourselves about nutrition and disease.

It’s quite useful to note that innovation in the field of nutrition often comes from the outside. Most of what you eat and the foods you purchase didn’t originate in some high-end scientific laboratory or in the hallowed halls of an Ivy League school.

Nutrition and dietary innovation is largely a grassroots affair. Here are examples: macrobiotics, the Atkins diet, the Mediterranean diet,  the Pritikin diet,  the Zone diet, the Paleo diet, The Death to Diabetes diet, veganism, raw foods, cleansing programs, orthomolecular nutrition, the use of supplements and herbs.

All of these ideas were brought to you by outsiders, some through ancient wisdom, some from people who have no formal university and scientific education, some from doctors who were considered to be on the fringe of quackery, and some from people who were desperate because they were dying from a chronic disease.

Key Learning Elements of Nutritional Science
If you plan to acquire a degree in nutritional science or teach yourself about nutritional science, there are several key components of nutritional science that you need to learn.

The first part of nutritional science is understanding the basic nutrients that are found in the foods we eat on a day to day basis.

The next part of nutritional science is learning how food influences our health: weight gain, disease, allergies, etc. Understanding which foods are good for your health and those which are bad is key to being able to help clients.

Another key component of nutritional science is understanding how food relates to exercise performance. Whenever exercise is undertaken, the body’s energy demands will go up considerably and different foods will impact exercise performance in different ways.

Nutritional science is also going to address how food will correlate to your own disease risk. With heart disease and diabetes on the rise in today’s world – two diseases that can be prevented largely through diet, more people are seeking help to prevent them.

When you study nutritional science, you’ll learn what factors most contribute to these diseases and how food can help to reverse the risk an individual sustains. Many people do not realize just how much power they have when it comes to reducing their chances of heart disease or diabetes, so the nutritional consultants role is to help raise awareness and then empower individuals to do something about it.

Truly understanding the science goes beyond “just the science”. You need to understand your client’s incentives, motivations, lifestyles, spirituality and other social influences to fully understand nutritional science systemically.

With more information coming out regularly on what nutrients and what foods best help beat some of the most prevalent diseases today, this is an ongoing area of nutrition science. Learning will never stop, so you can really grow into this field if you wish.

Finally, as you study nutritional science you’ll also learn how to interact with clients so that you can help them learn how to manage their lifestyle better with superior nutrition choices.

Many clients struggle to eat healthy for a number of reasons, so nutritional science will look at why this is and what can be done to overcome some of the problems that are in place.

Since eating is not just the simple act of fueling the body, but rather, people eat for a wide number of reasons (happiness, fear, sadness, in social environments, etc.), it’s important to understand how these correlate to food choices, health, and body weight, and then make recommendations for ways to best manage eating in these situations to prevent negative impacts on the body.

Nutritional science encompasses many different areas and will provide the learner with ongoing challenges to expand their knowledge and then put it into practice with the clients they work with. 

The bottom line: Acquire knowledge from multiple sources about nutritional science in order to acquire the power to help yourself and others.
