The Intestinal Microflora

When our intestinal microflora system is in proper balance, there are numerous potential benefits. These benefits may include helping in the prevention of certain conditions (Shi et al., 2004).

Having a healthy intestinal microflora system may help support the immune system. When our intestinal microflora balance shifts in favor of "beneficial" microbes, the pH of our intestinal tract tends to swings downward, making it a less hospitable environment for harmful bacteria, because as the numbers of beneficial bacteria in the intestinal tract increase, the production of lactic, butyric and acetic acids rises.

Intestinal microflora also plays an important role in the maturation of our immune systems and in the development of normal gastro-intestinal function. The microflora that occupies the lining of our intestinal tract acts as a physical barrier. It reinforces the barrier function of the intestinal mucosa by partially blocking the passage of bacteria and allergens in foods. Conversely, an unbalanced microflora system will adversely affect these intestinal functions.

There is even a growing body of evidence that certain intestinal bacteria have the ability to manufacture a variety of nutrients and enzymes including biotin, B-complex vitamins and vitamin B12.
