Effects of the Short-Chain Fatty Acids-Targeted Dietary Interventions on the Selected Autonomic Functions in Humans

Participants will receive potato starch supplement, undergoing gut microbial fermentation and acting as an endogenous source of the short-chain fatty acids, including butyrate. Effects of these compounds on the selected autonomic functions (i.e. cardio-respiratory control) will be further investigated.

Participants will receive sodium butyrate supplement, acting as an exogenous source of the short-chain fatty acid butyrate. Effects of such compound on the selected autonomic functions (i.e. cardio-respiratory control) will be further investigated.

Participants will receive the accessible (digestible) waxy maze starch as placebo.
