How good bacteria can prevent obesityA new study has discovered that good bacteria can play an important role to prevent obesity and type -2 diabetes. These findings suggest that foods that stimulate the production of bacteria in the digestive system could help to facilitate faster weight loss than eating less and exercising more.

The study published in Proceedings of the National Academy of Sciences, found that the levels of bacteria Akkermansia muciniphila were much lower in mice who were obese and with type-2 diabetes.

Feeding these mice oligofructose prebiotics increased the growth of good bacteria and re-balanced levels back to normal levels. This stimulated metabolism in the mice which caused weight loss. Other benefits were a reduction in inflammation and a reduction in insulin resistance.

Prebiotics should not be confused with probiotics. Prebiotics do not replace bad bacteria in the gut, but they serve as food for friendly bacteria such as lactobacillus and bifidus. Prebiotics help the probiotics to multiply which leads to a healthier digestive system and immune system.

Prebiotics are found in many foods such as banana’s, chicory, onions, leeks, asparagus and artichokes.

The researchers suggest that the bacteria, Akkermansiamuciniphila, could play an important role in reducing inflammation, weight loss and maintaining blood sugar balance.

Professor Patrice Cani, of the Catholic University of Leuvenin Belgium, said: ‘This study demonstrated the abundance of A. muciniphila decreased in obese and type 2 diabetic mice.

‘In summary this study provides substantial insight into the intricate mechanisms of A. muciniphila regulation of the cross-talk between the host and gut microbiota.

‘These results also provide a rationale for the development of a treatment that uses this human mucus coloniser for the prevention or treatment of obesity and its associated metabolic disorders.’
