FDA-approved artificial sweeteners and sport supplements are toxic to digestive gut microbes, according to a new paper published in the journal Molecules by researchers at Ben-Gurion University of the Negev (BGU) in Israel and Nanyang Technological University in Singapore.
The collaborative study indicated relative toxicity of six artificial sweeteners (aspartame, sucralose, saccharine, neotame, advantame, and acesulfame potassium-k) and 10 sport supplements containing these artificial sweeteners. The bacteria in the digestive system became toxic when exposed to concentrations of only one milligram per milliliter of these substances.
