Our P.B.F. Prebiotic Balanced Fiber blend works through the digestive system and delivers prebiotic fibers to nourish the billions of bacteria. Our prebiotic ingredients are resistant to digestion in the stomach and small intestine but are totally or partially fermentable in the large bowel.
The P.B.F. prebiotics often results in a lower pH in the large bowel. Short-chain fatty acids (SCFA) generated by fiber fermentation by gut bacteria trigger changes in nervous system functioning and behavior.
The major SCFA’s produced are acetate, propionate, and butyrate, and each has an important role in the gut and in host animal metabolism. SCFA are the main source of energy for the cells lining of the colon. SCFA produced by microbial fermentation of plant fibers are also involved in glucose regulation. Inside the large intestine, short-chain fatty acids affect immunity, strengthen the intestinal wall, and feed the cells lining the gut.

What is the process of how fiber is digested by microbes and creates short-chain fatty acids?
- Fiber gets to the large intestine and is devoured by microbes.
- Microbes feast on fermentable fibers that resist digestion.
- Microbes extract the fiber’s energy, nutrients, vitamins and other compounds.
- Short-chain fatty acids are obtained from fiber fermentation and have been linked to improved immune function, decreased inflammation and protection against obesity. *
