FDA approved artificial sweeteners and some sports supplements were found to be toxic to digestive gut bacteria in new studies. Their consumption can adversely affect gut microbial activity, causing a wide range of health issues from cancers, weight gain, metabolic disorders, type-2 diabetes and alteration of gut microbiota activity. The research was published in Molecules by researchers at Ben-Gurion University of the Negev (BGU) in Israel and Nanyang Technological University in Singapore.
