SCFAs are the end product of the bacterial fermentation process of dietary fiber by beneficial flora in the gut and play an important role in the health of the GI as well as protecting against intestinal dysbiosis.
Lactobacilli and bifidobacteria produce large amounts of short chain fatty acids, which decrease the pH of the intestines and therefore make the environment unsuitable for pathogens, including bacteria and yeast.
Studies have shown that SCFAs have numerous implications in maintaining gut physiology.
SCFAs decrease inflammation, stimulate healing, and contribute to normal cell metabolism and differentiation.
It normally comprises approximately 2% of the total fatty acids in stool.
