Short-Chain Fatty Acids Regulate Immunity, Protect the Brain, and Fight Inflammation

Produced by the fermentation of dietary fiber in the intestines, short-chain fatty acids are crucial in maintaining a healthy weight, immune system, and mind.

Short-chain fatty acids are vital for intestinal immune system regulation and brain health. However, they are not produced by the breakdown of fat but through the fermentation of dietary fiber by intestinal bacteria. Meals rich in dietary fiber, combined with proper exercise, can help you maintain normal levels of short-chain fatty acids.

Short-Chain Fatty Acids

Short-chain acids are produced when dietary fiber, undigested in the small intestine, enters the large intestine and is fermented by intestinal microorganisms.

The main components of short-chain fatty acids are acetate, propionic acid, and butyric acid.

1.  Acetate

Acetate accounts for about 60 percent of short-chain fatty acids. It is absorbed into the bloodstream by the intestines and can reach the brain via the blood-brain barrier as blood circulates, so it has a significant effect on the nervous system.
