Low-calories sweeteners might not be as good for us as we thought

Some artificial sweeteners disrupt the microbes in our gut – possibly in ways that increase the risk of weight gain, diabetes, and heart disease, says a recent study.

The disruption to the microbiome occurs because non-nutritional sweeteners, although zero or low calorie for humans, serve as nutrients for some microbes, which then proliferate. This causes an imbalance in microbial populations that can cause chronic intestinal inflammation or colon cancer.
