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.

Plasma SCFA levels can be modulated by altering dietary fibre consumption in healthy individuals with increments similar to those achieved in murine studies. Five days of diet intervention did not result in changes in regulatory T-cell proportions and cytokine concentrations in peripheral blood, and may require longer duration of dietary change.
