The large intestine, an important region of the gastrointestinal tract, is populated with bacteria that maintain our bodies healthy. The term used to describe these organisms that live in the digestive tract is gut microbiota.
The relationship between humans and the gut microbiota is not only non-harmful but also beneficial to humans. <u>Bacteria ferment dietary fibers into </u><u>short-chain fatty acids</u><u> for us to absorb it</u>. Gut microbiota also plays a crucial role in synthesizing vitamin B and vitamin K, as well as metabolizing <u>sterols and bile acids</u>. These bacteria act much like an endocrine system that regulates intestinal function with the use of short-chain fatty acids, as if they were hormones.
<u>Vitamin K</u><u> is important for</u><u> blood clotting</u><u>, while </u><u>vitamin B</u><u> intervenes in </u><u>cellular metabolism</u>.
