How does the human gut microbiome help digestion?

Quick Answer

Gut microbes help break down some foods, produce certain vitamins, and influence the immune system. They live mainly in the large intestine.

The Full Story

The human digestive tract contains trillions of microorganisms, especially in the colon. These microbes help ferment dietary fibers that human enzymes cannot digest, producing short-chain fatty acids that can support colon health. They also contribute to vitamin production, including vitamin K, and help train the immune system. The balance of microbial species can be influenced by diet, antibiotics, and illness.
