Propionate is observed to be among the most common short-chain fatty acids produced by human gut microbiota in response to indigestible carbohydrates (fiber) in the diet. A study in mice suggests that propionate is produced by the bacteria of the genus Bacteroides in the gut, and that it offers some protection against Salmonella there. Another study finds that fatty acid propionate can calm the immune cells that drive up blood pressure, thereby protecting the body from damaging effects of high blood pressure.

The fatty acid propionate helps defend against the effects of high blood pressure, ... Gut bacteria produce the substance – which calms the immune cells that drive up blood pressure – from natural dietary fiber
