Intestinal Flora Support Information (Gastrointestinal System)

INTESTINAL FLORA SUPPORT (THE GASTROINTESTINAL SYSTEM)

The cells of the gastrointestinal tract ensure proper delivery of vital nutrients to all cells of the body. Starting with hydrochloric acid and pepsin in the stomach, food starts to break down into the usable nutrients and fuel we need to survive. Hydrochloric acid (HCL) not only digests protein, it provides the proper pH for the prevention of bacterial/microbial invasion. The proper pH is also necessary for subsequent hormonal signals to the digestive process. The production of HCL decreases with age. Bile from the gall bladder enters the small intestine and emulsifies the fat and prepares it for digestion, while pancreatic enzymes break down protein, carbohydrate, and fat. Complete absorption of fat is necessary for the absorption of fat-soluble vitamins. The digested food is then absorbed through the wall of the small intestine into the blood and lymph, to circulate to the tissues. The integrity of the intestinal wall functions as an immune barrier, and also as a physical barrier to substances such as macromolecules which can potentially activate the immune system when they are not completely digested. Healthy mucosal cells produce protective factors, such as mucous and bicarbonate, which prevent damage to the lining. Glutamine is the major fuel of the small intestine, and one of the most important fuels for the large intestine; glutamine contributes to the health of the mucosal cells, and to the integrity of the barrier, to prevent leakage of unwanted substances into the bloodstream.

The colon, or large intestine, is the final elimination pathway in the body and functions to remove harmful toxins. A balance of flora (bacteria) exists in the colon, as a vital part of the immune system. The good bacteria in this balance are responsible for producing several vitamins, including vitamin K and many B vitamins. Fiber has been associated with a decreased risk for many diseases, especially those of the lower bowel. Fiber exercises the colon, provides bulk, and breaks down in the large intestine to butyrate, which is its major fuel. This fuel lowers the pH of the colon, which is known to have a favorable effect on the wave-like contractions of the intestinal wall, and helps to support normal bowel functioning. It is believed that an environment free of harmful microorganisms and toxic substances is essential to the health of the colon.
