Summary
Dagbasi, Cai, Hirdaramani and co-authors synthesize fragmented evidence on acetate, propionate and butyrate, mapping how gut microbes produce these short-chain fatty acids and how they act across organ systems.
The review ties SCFA output to diet and microbiome ecology, highlighting non-digestible carbohydrates, cross-feeding between microbes and food structure as major drivers of production.
It then outlines the main mechanisms behind SCFA effects—receptor signaling, epigenetic regulation and tissue-specific actions influencing metabolism, immunity, appetite and physiological homeostasis.
Published as inadequate dietary fibre intake becomes a wider public health concern, the paper argues SCFA pathways could be targeted through dietary strategies and future therapeutics to support metabolic health and disease prevention.
