How bacteria reduce your cholesterol levels
Scientists have found bacteria in our guts that degrade cholesterol. These bacteria can reduce our overall cholesterol levels and might have health benefits for us.
Some gut bacteria quietly work on molecules from our food before our body even sees them. Eubacterium is one of those useful gut residents, since some of them are specialised fibre degraders involved in cholesterol metabolism.
For example, Eubacterium coprostanoligenes can convert cholesterol into coprostanol. This reduces free cholesterol in the gut, a process potentially relevant for blood cholesterol levels.
Eubacterium also produce short-chain fatty acids, including butyrate. Short-chain fatty acids are products of gut microbes processing food-derived molecules, which contribute to metabolic activity in the gut.

Your gut microbiome is full of helpful and fascinating bacteria. They all work together to keep you healthy, digest your food and fight off intruders. Here, you will learn about what a healthy gut microbiome is, what it does and how to keep it.
