Artificial sweeteners are toxic to gut flora

October 2, 2018


Artificial sweeteners have toxic effects on gut microbes…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 found in the digestive system became toxic when exposed to concentrations of only one mg./ml. of the artificial sweeteners…FDA-approved artificial sweeteners and sport supplements were found to be toxic to digestive gut microbes, according to a new paper published in Molecules by researchers at Ben-Gurion University of the Negev (BGU) in Israel and Nanyang Technological University in Singapore…Artificial sweeteners are used in countless food products and soft drinks with reduced sugar content…”

“...Recent research found even more evidence that artificial sweeteners can harm you. Scientists at Ben-Gurion University of the Negev in Israel, and Nanyang Technological University in Singapore, analyzed how FDA-approved artificial sweeteners and sport supplements could affect E. coli bacteria. Published in Molecules on September 25, the study revealed that they could have toxic effects on E. coli, and therefore on human health…The team looked at six artificial sweeteners: aspartame, sucralose, saccharine, neotame, advantame and acesulfame potassium-k. They also analyzed 10 sport supplements containing those sweeteners to determine their toxicity…some whole wheat breads at grocery stores contain sucralose, which is the main ingredient in Splenda, to help sweeten the taste of whole wheat. Pedialyte contains acesulfame potassium-k, and aspartame is used to sweeten some diet drinks. Those artificial sweeteners are also found in microwave popcorn, fruit juice, yogurt and many other items, even when the label reads ‘natural sweeteners,’ since the FDA doesn’t have a legal definition of the word ‘natural.’ The scientists looked specifically at how they affected E. coli...The study confirmed the results of a 2014 study in Nature, which looked at how the sweeteners can lead to glucose intolerance, likely due to their effect on the gut microbiome. Prior research found that artificial sweeteners lead to obesity and diabetes in mice and might even make gut issues stemming from Chron’s disease even worse…”
