What crucial metabolites are generated when gut bacteria ferment resistant starch in the large intestine?
Answer
Short-chain fatty acids (SCFAs)
Resistant starch, found in potatoes when consumed with the skin, acts as a prebiotic fiber because it bypasses digestion in the upper GI tract. Once this starch reaches the large intestine, the resident gut bacteria commence fermentation of it. This essential fermentation process results in the generation of critical metabolites known as Short-Chain Fatty Acids (SCFAs). These SCFAs are vital components required for maintaining gut homeostasis, aiding in inflammation control, and supporting overall digestive tract health.
