These acids serve as a source of energy for intestinal cells, and also help the body fight germs and viruses. This was told by a dietitian-therapist, candidate of medical sciences, cardiologist and executive director of the ANO Research Center “Healthy Nutrition” Svetlana Pavlichenko.

SCFAs are formed in the large intestine when microbes ferment soluble fiber (inulin and pectin) as well as various forms of resistant starch. Therefore, foods that contain a lot of substances from which short-chain acids can be obtained are the most beneficial for immunity.
