Spotlight On: Short-chain Fatty Acids
Credit: iStock/VectorMine The gut microbiota in our body produces various substances called metabolites. One of those metabolites is short-chain fatty acids (SCFAs). These are the compounds our digestive system produces when dietary fiber that we can’t digest ferments in the gut. Acetate, butyrate and propionate are some of the major SCFAs. SCFAs are important biofuels … Continue reading Spotlight On: Short-chain Fatty Acids
