Artificial sweeteners are used as an additive in both beverages, as well as food, to improve taste since most people prefer a sweet taste.Since these sweeteners contain very few calories, they are also popular in diet beverages and diet foods. They are even used in products marketed to people with diabetes and promoted as a good alternative to sugar.This seems to be a big mistake according to the reviewed research(Suez J, et al. 2014). The results demonstrated that consumption of these sweeteners are causing glucose intolerance because they alter the composition of the intestinal bacterial flora in a negative way. These results have been reproduced in both humans and mice.The last thing you want to do is to consume a substance that will make you more glucose intolerant. This is very important for diabetics, but also for non diabetics because you don't want to develop diabetes.
