Short-Chain Fatty Acids
Short-chain fatty acids (SCFAs)—mainly acetate, propionate, and butyrate—are made when gut bacteria ferment fiber in the colon. They fuel colon cells, support immune signaling, and may improve insulin sensitivity when production is steady.

Low fiber intake or abrupt antibiotic courses can shrink SCFA output.
