Helpen zoetstoffen om gewicht kwijt te raken en diabetes te voorkomen?
Nee, dat bevorderen ze juist.
Nieuwe studie: als onze ingewandsbacterieën blootgesteld worden aan zoetstoffen veroorzaken ze schadelijke veranderingen in onze stofwisseling.
Eén van de mogelijke gevolgen: het bevorderen van glucose (suiker) intolerantie, beginnende diabetes. Daarmee komen ook andere metabole ziekten in beeld.

Certain gut bacteria may induce metabolic changes following exposure to artificial sweeteners

Summary:
Artificial sweeteners have long been promoted as diet and health aids. But breaking research shows that these products may be leading to the very diseases they were said to help prevent: scientists have discovered that, after exposure to artificial sweeteners, our gut bacteria may be triggering harmful metabolic changes.
Artificial sweeteners -- promoted as aids to weight loss and diabetes prevention -- could actually hasten the development of glucose intolerance and metabolic disease, and they do so in a surprising way: by changing the composition and function of the gut microbiota -- the substantial population of bacteria residing in our intestines.
These findings, the results of experiments in mice and humans, were published September 17 in Nature. Dr. Eran Elinav of the Weizmann Institute of Science's Department of Immunology, who led this research together with Prof. Eran Segal of the Department of Computer Science and Applied Mathematics, says that the widespread use of artificial sweeteners in drinks and food, among other things, may be contributing to the obesity and diabetes epidemic that is sweeping much of the world.

The findings showed that many -- but not all -- of the volunteers had begun to develop glucose intolerance after just one week of artificial sweetener consumption. The composition of their gut microbiota explained the difference: the researchers discovered two different populations of human gut bacteria -- one that induced glucose intolerance when exposed to the sweeteners, and one that had no effect either way.
