Fermentation of non-starch polysaccharides by colonic microflora produces short-chain fatty acids (SCFAs), particularly butyrate, which promotes large bowel health, inhibits pathogenic organisms, and may offer a prebiotic effect.

Include a variety of fibrous plant foods in your diet to feed your gut bacteria. These bacteria ferment the fiber into beneficial compounds like butyrate, which support colon health and may help protect against colorectal issues.

a major proportion of dietary NSPs escapes the small intestine nearly intact, and is fermented into SCFAs by commensal microflora present in the colon and cecum and promotes normal laxation. Short chain fatty acids have a number of health promoting effects... Certain NSPs through their fermented products may promote the growth of specific beneficial colonic bacteria which offer a prebiotic effect.
