Deficiencies of specific vitamins and minerals that play important roles in glucose metabolism and insulin signaling pathways may contribute to the development of type 2 diabetes. Shifting from a diet that is nutrient-poor to one that is nutrient-dense, low glycemic and high fiber is important, and a diet rich in certain vitamins and minerals can help you avoid nutrient deficiencies that are associated with type 2 diabetes and insulin resistance. A diet rich in plant foods including fresh whole fruits and vegetables, nuts, seeds, beans and whole grains (like a Mediterranean style diet) can improve how genes that control insulin function and obesity work (where obesity is associated with insulin resistance and type 2 diabetes). Along with eating a nutrient-dense diet to resolve nutrient deficiencies, lifestyle modification (including stress management), engaging in interval training and physical activity, and the appropriate use of dietary supplements can enhance mitochondrial function (energy production) and reduce oxidative stress, where these factors are important for improved glycemic (blood sugar) control.
Incorporate these nutrients into your diet to help manage insulin resistance and type 2 diabetes
Nutrients important for managing insulin resistance and type 2 diabetes: Vitamin B3, vitamin B12, biotin, vitamin C, vitamin D, vitamin E, inositol, carnitine, glutamine, CoQ10, glutathione, cysteine, lipoic acid, zinc, magnesium, chromium, vanadium, quercetin, resveratrol, omega 3 fats (EPA and DHA), PABA, GABA, antioxidants
Foods containing nutrients for the management of insulin resistance and type 2 diabetes
B3: Tuna, chicken, turkey, salmon, lamb, beef, sardines, brown rice
B12: Choose methylcobalamin for supplemental source, sardines, salmon, tuna, cod, lamb, beef, liver, chicken, fish, eggs, rainbow trout, haddock
Biotin: Eggs, legumes, meats, oily fish, chicken, liver
Vitamin C: All will be higher in vitamin C if uncooked. Bell peppers, papaya, citrus fruits, Brussels sprouts, strawberries, kiwi
Vitamin D: Salmon, herring and sardines, cod liver oil, canned light tuna (lower in mercury), oysters, egg yolk, mushrooms
Vitamin E: Sunflower seeds, spinach, Swiss chard, avocados, turnip greens, asparagus, mustard greens
Inositol: Inositol is found in cereals and vegetables as phytic acid (combination of inositol and phosphorus). Lecithin granules, beef heart, desiccated liver, wheat germ, lecithin oil, liver, brown rice, citrus fruits, nuts, leafy green vegetables, molasses
Carnitine: Beef steak, ground beef, pork, whole milk, cod, chicken breast, avocado, asparagus
Glutamine: Beef, chicken, fish, eggs, beets, beans, spinach, parsley
CoQ10: Meat, poultry, fish
Glutathione: Undenatured whey protein, asparagus, curcumin/turmeric, avocado, spinach, garlic, foods high in vitamin C (e.g., citrus fruits) and selenium
Cysteine: Beef, chicken, lamb, fish
Lipoic acid: Broccoli, spinach, red meat, organ meat, Brussels sprouts, peas, tomatoes, beets, carrots, Brewer's yeast
Zinc: Beef, lamb, pumpkin seeds, lentils, garbanzo beans, quinoa, turkey
Magnesium: Halibut, spinach, chard, oatmeal, potatoes, black-eyed peas, brown rice, lentils, avocados, pinto beans
Chromium: Brewer's yeast, mussels, oysters, pears, Brazil nuts, hazelnuts, tomatoes, broccoli, egg yolk, prunes, herring, dried basil, turkey breast, cheese, organ meats. Food rich in vitamin C (red peppers, citrus fruits, strawberries) can improve absorption of chromium.
Vanadium: Mushrooms, shellfish, black pepper, parsely, dill weed, beer, wine, whole grains, tomatoes, green beans, corn, carrots, garlic, radishes, onions, cabbage
Quercetin: Apples, peppers, red wine, dark cherries and berries, cruciferous vegetables, tomatoes, leafy greens, citrus fruits, whole grains, raw asparagus, raw red onion, olive oil, black and green tea, beans/legumes, cocoa
Resveratrol: Grapes, red and white wine, peanuts, pistachios, blueberries, cranberries, cocoa, dark chocolate
DHA and EPA: (Essential Fatty Acids/Omega 3s/healthy fats) Cell membranes are made of cholesterol and phospholipids, need to make sure there are plenty of healthy fats in your diet daily, and essential fatty acids reduce inflammation, and assist with gut and skin healing. Flaxseed, eggs, fish and fish oils, marine sources (sea vegetables/seaweeds), avocado, coconut oil
Para-aminobenzoic acid (PABA): Whole grains, folate rich vegetables (mushrooms, spinach, dried beans, lentils, split peas, potatoes, sweet potatoes, beet root, Brussels sprouts, dark leafy greens, kale, bok choy, asparagus, oranges, peaches), Brewer's yeast
Gamma-aminobutyric acid (GABA): Fermented foods (kimchi, kefir, miso, sauerkraut, tempeh, yogurt). Flavonoid phytonutrients may enhance GABA function (berries, citrus fruits, apples, pears, tea, cocoa, wine).
Antioxidants: Virtually all plant foods, such as fresh fruits and vegetables, nuts and seeds, kidney beans, dark chocolate
Avoid High Mercury Fish
High mercury fish: Bluefish, grouper, mackerel (Spanish, Gulf, King), marlin, orange roughy, sea bass (Chilean), shark, swordfish, tilefish, and tuna (canned albacore, yellowfin, bigeye, ahi)
Low mercury fish: anchovies, butterfish, catfish, croaker (Atlantic), flounder, haddock (Atlantic), hake, herring, mackerel (North Atlantic, chub), mullet, perch (ocean), pollock, salmon (fresh, wild), sardines, sole (Pacific), squid, tilapia, trout (freshwater), whitefish, and whiting
Go organic when possible for fruits and vegetables.
Go organic, pastured, free range, grass fed, wild caught, etc. for animal products.
