How bacteria reduce our cholesterol levels

Scientists have identified bacteria in our guts that degrade cholesterol. These bacteria can reduce our overall cholesterol levels and might have health benefits for us.

Cholesterol passes through the gut. Hence, researchers already suggested that bacteria might have something to do with the varying cholesterol levels in our plasma. 

But scientists had no idea how cholesterol levels and gut bacteria could be linked.

A previous study looked at the Asian dish Tapai, which is fermented cassava or rice. A special Lactobacilli strain from this dish has probiotic effects in rats and can degrade cholesterol.  

Now, a new study used some fancy techniques to find new bacteria that reduce cholesterol levels.
