Nutrients for the Digestive TractBy Mary G. Enig, PhD & Sally Fallon![]() Vitamin A, our favorite vitamin, is absolutely critical to the health of the intestinal mucosa. Without sufficient vitamin A, the mucous membranes become hardened and, paradoxically, more easily penetrated, leading to "leaky gut, " ulceration and irritable bowel syndrome. Vitamin A is also necessary for the assimilation of minerals and protein and plays an important role in the repair process. It has been used successfully to treat gastritis. Best sources are cod liver oil followed by liver and other organ meats, and butterfat and egg yolks from grassfed animals. Vitamin B Complex is important for fat metabolism and liver health; B vitamins play a role in the production of bile. They are necessary to maintain muscle tone, stimulate digestive secretions, support the nervous system and ensure normal carbohydrate metabolism. We recommend Frontier brand nutritional yeast as a supplement along with a diet of whole foods to ensure adequate B vitamins. Vitamin C complex contributes to the health of all the epithelial cells as well as the integrity of the blood vessels that nourish the intestinal tract. Vitamin C is necessary for biochemical repair. Lacto-fermented fruits and vegetables are especially good sources. Vitamin D plays a role in fighting inflammation and strengthening the immune system, as well as in the assimilation of calcium and other important minerals. Crohn’s disease is associated with vitamin D deficiency. Best sources are cod liver oil, lard from pastured pigs, oily fish, fish eggs, shellfish, and butterfat and egg yolks from grassfed animals. Vitamin E is needed for muscle tone and a healthy nervous system. Deficiency has been linked to digestive problems such as peptic ulcers, colitis, constipation and cancer of the colon. Best sources are small amounts cold-pressed oils (too much polyunsaturated oil can deplete vitamin E), whole grains, butter and other animal fats and a supplement of wheat germ oil. Protein is necessary for the maintenance of the mucous membrane in the stomach, particularly the amino acids cystine, lysine and arginine. Deficiency leads to muscular weakness and many other problems. Bone broths are an excellent source of arginine, and cystine and lysine occur in meat, milk and eggs. Phosphatidylcholine (PC) has been studied by German researchers who found that PC is highly beneficial to the mucosal lining of the digestive tract, preventing or healing lesions and reducing the incidence of stomach ache. They found that PC was more effective than nonsteroidal anti-inflammatory drugs (NSAID) in reducing gastric mucosal lesions. The researchers used PC derived from soy, but the best dietary sources are egg yolks and butter. CoEnzyme Q10 is critical for healthy muscles. The importance of good muscle tone is often overlooked in discussions about digestion. The best source is meat, especially heart. Cholesterol plays a role in intestinal health. The cells lining the digestive tract are particularly rich in cholesterol. Cholesterol is also the precursor to bile. It is provided only by animal foods. Salt is key to digestion. Salt provides chloride for hydrochloride, necessary for the digestion of protein; and salt activates an enzyme needed for the digestion of carbohydrates. Calcium prevents cramps and spasms, protects against inflammation and supports both the muscles and the nervous system. Best sources are raw dairy products and bone broths. Potassium supports the nervous system and connective tissue, as well as the production of hydrochloric acid. Best sources are meats, whole grains and vegetables. Zinc deficiencies have been associated with problems of fat metabolism, inflammatory bowel disease and Crohn’s disease. Best sources are red meat and oysters. Beneficial Bacteria help maintain a healthy ecosystem in the gut. Best dietary sources are natural yoghurt and lacto-fermented condiments and beverages. Supplements such as Primal Defense from Garden of Life can help repopulate the digestive tract very quickly in cases of digestive disorders.
