How gut flora can influence obesity

artikel-2b_header

A rich intestinal flora is crucial for good health. However, when the intestinal flora is disturbed, all sorts of problems can manifest. Although scientists are still trying to discover what comes first, there is a strong link between obesity and poor intestinal flora.

People with a poor bowel culture have fewer bacteria that produce short-chain fatty acids, such as Roseburia and Faecalibacterium. These fatty acids ensure a faster transition of food through the gastrointestinal tract. Therefore, the body is slimmer and due to the absence of obesity, the risk of cardiovascular disease is reduced. These fatty acids also have an effect on our metabolism, as they help regulate the balance of fat.

It’s these fatty acids that operate in the small intestine, with your colon being host to Akkermansia muciniphila. This bacterium lives in the mucous lining of the intestinal wall and influences your weight and fat percentage. The slimmer you are, the more Akkermansia you have in your intestines and vice versa. Indirectly, this means that the risk of diabetes will decrease when your Akkermansia count rises.

Then again, a poor intestinal flora means you are likely to have more potential pro-inflammatory and less anti-inflammatory bacterial species. The bacterium Akkermansia again is hugely beneficial as it encourages its host to release molecules that kill these harmful bacteria and prevent inflammations.
