Diet impacted by different balance of microbes in the gut

A new study, published by the Sahlgrenska Academy in the journal Cell , has revealed that a dietary treatment works for some individuals and it depends on interactions between the gut and the diet.

“Our findings clearly show the importance of the interaction between the gut and the diet and contribute to our understanding of in and disease. The results may help to explain why responses to different dietary treatments are so individual,” says Professor Fredrik Bäckhed at the Sahlgrenska Academy, University of Gothenburg.

The study evaluated 39 who ate barley kernel bread for three days followed by control bread for three days. Barely kernel bread consumption improved control of blood sugar in some individuals but not in others.

Prevotella bacteria was present in higher proportions in those individuals who responded to barley kernel bread than in those people who did not respond to this . Previous studies have indicated that altered gut is involved in such as , and that the gut contributes to obesity, diabetes and .

“It is incredibly exciting to see the link between the gut and various dietary fibers, which can help us develop more individualized dietary guidelines,” said Professor Inger Björk at .

“Our results also show that control of blood sugar is improved in mice supplemented with Prevotella if they are given a high-fiber diet. Our findings could lead to a combination product with Prevotella and fiber from grains,” said Fredrik Bäckhed at the Sahlgrenska Academy.
