Artificial sweeteners have been in the spotlight of many investigations by the possibility of having adverse effects on the health. It has been spoken of the influence of some bulk sweeteners in reference to glucose intolerance, as well as in the alterations of the intestinal microbiota. But that, what is scientifically proven?
Aspartame and saccharin are two of the artificial sweeteners most commonly used. Numerous studies have tried to reveal its influence on the changes in the composition of the intestinal microbiota.
As published 20 minutes, the Iberoamerican Nutrition Foundation (FINUT) refers, in the first place, that all sweeteners are subject to a control of food safety, so that all of them are authorized by the corresponding organizations. However, it also notes that the health effects of its consumption can give rise to controversy.
After the analysis of different experiments on this topic, FINUT concludes that sweeteners derived from amino acids such as, for example, one of the most consumed is the aspartame, do not entail any alteration in the intestinal microbiota.
In terms of the low-calorie sweeteners, only the saccharin and sucralose may have the ability to alter the microbiota, but the study concludes that more research is needed to confirm these effects.
Finally, make reference to the sweeteners-type polyol, for example, the e, the maltitol, the lactitol and xylitol. These sweeteners are not absorbed, so they act as prebiotics, and there is a possibility that they reach the intestine and yes increase the number of bifidobacteria.
