Friendly bacteria are critically important for the health
of our digestive and immune systems, for their detoxification
and hormone-regulating capabilities, and for nutrient formation and absorption. Effective treatment of dysbiosis with diet, antimicrobial substances and bacterial replacement or support must distinguish among patterns of dysbiosis. The failure of common approaches utilizing fiber and Lactobacilli alone is a strong indication of small bowel bacterial overgrowth, a challenging disorder which demands a radically different approach from a dysbiosis of the large intestine. Stool examination generally reflects large bowel bacterial colonization. Other testing means are required for uncovering bacterial overgrowth in the small intestine.
Putrefaction dysbiosis is usually managed with a diet high in both soluble and insoluble fiber and low in saturated fat and animal protein. These dietary changes work to lower the concentrations of Bacteroides and increase concentrations of lactic acid-producing bacteria (Bifidobacteria, Lactobacillus and lactic acid streptococci) in the colon. Supplementing the diet with defined sources of fiber can have variable effects on colonic dysbiosis. Insoluble fiber decreases bacterial concentration and microbial enzyme activity. Soluble fiber, on the other hand, tends to elevate bacterial concentration and enzyme activity, at the same time raising the levels of beneficial short chain fatty acids. This disparity may explain the superior effect of insoluble fiber in the prevention of colon cancer.
