Successful elevation of circulating acetate and propionate by dietary modulation does not alter T-regulatory cell or cytokine profiles in healthy humans: a pilot study

Increased circulating concentrations of short-chain fatty acids (SCFA) achieved by ingestion of high-fibre diets is associated with anti-inflammatory effects through promotion of FoxP3+ regulatory T(reg) cells in mouse models. This study aimed to determine whether similar increments in blood SCFA levels can be achieved in humans and whether these are associated with similar immune modulatory effects. In a pilot single-blinded, randomised,...
