Digestive health depends on a group of short chain fatty acids (SCFAs) that are formed through the fermentation of undigested fiber. SCFAs help ensure the health of the colon and prevent the reuptake of toxins. Low levels and decreased metabolism of these compounds are associated with chronic digestive conditions like Crohn’s disease. The common SCFAs include acetate, propionate, and butyrate which are the primary metabolic energy source for colonic epithelial cells.
