Specific Gut Microbes are Linked to a Lower Risk of Infection

Posted by in categories: biotech/medical, chemistry, health

There are trillions of microbes in the human gastrointestinal tract, each of which expresses its own genome, and carries out a variety of biochemical processes. Gut microbes can generate a variety of molecules that can have a significant impact on human health, such as vitamins, specially modified bile acids, and short-chain fatty acids (SCFAs).

SCFAs have fewer than six carbon atoms, and are found in a few major forms, including acetate, propionate, and butyrate. When we eat fibers that are tough to digest, gut microbes metabolize them instead, and generate SCFAs. Many links have been found between butyrate and human health; it is thought to have roles in the maintainence of epithelial barriers, prevention of gut inflammation in the gut and colorectal cancer, and oxidative stress relief.
