Gut Bacteria May Influence Body Weight, Fat and Cholesterol Levels: Study

Trillions of bacteria and other microbes present in our gut play a significant role in overall health. These microbes influence everything from digestion to immune system and hence also referred as an extra organ of the body.

New research highlights the impact of gut bacteria on our body weight, fat and HDL (good cholesterol levels), which are the main factors  necessary for maintaining a healthy heart, according to the  Circulation Research, an American Heart Association Journal.

"As less than 30 percent of bacteria in the human gut have been cultured, we know very little about who they are and what they do. With state-of-art deep sequencing technology, we are now able to identify them,” said Dr Jingyuan Fu, an associate professor of genetics at University Medical Center Groningen.

Researchers analyzed the relationship between the microbes and blood lipid levels in 893 people using data collected from the Netherlands. They found 34 different types of bacteria that lead to the differences in BMI (Body Mass Index) and blood lipids: triglycerides and high-density lipoprotein (good cholesterol levels). The results showed that bacteria contributed to 4.6%, 6% and 4% respectively of the difference in body fat, triglycerides and HDL.

"Our study provides new evidence that microbes in the gut are strongly linked to the blood level of HDL (good cholesterol) and triglycerides and may be added as a new risk factor for abnormal blood lipids, in addition to age, gender, BMI and genetics," said Fu.

Although more diverse and comprehensive studies are required, our hope is for the identification of the bacteria to aid in the development of new therapies as a means to prevent heart disease, researchers add.
