How gut bacteria influence weight, heart health
CBS News

The trillions of bacteria and other microbes living in our gut play an important role in overall health, influencing everything from the effectiveness of our immune system to cancer risk to our mental health.

Now, new research highlights the impact of the gut’s microbiome on weight and heart health. A study, published in the American Heart Association journal Circulation Research, found that bacteria living in the gut may impact weight, fat and good cholesterol levels, all factors necessary in maintaining a healthy heart.

Researchers from University Medical Center Groningen in the Netherlands used state-of-the-art deep sequencing technology to study the association between gut microbes and blood lipid levels in 893 people.

They identified 34 different types of bacteria that played a role in the differences in body fat (BMI) and blood lipids, such as triglycerides and the good cholesterol known as high-density lipoprotein (HDL). Most of these were new discoveries.
