Nonnutritive sweeteners and the gut microbiome Original paper

    In adults without diabetes, two weeks of consuming saccharin or sucralose resulted in higher blood glucose responses, whereas consuming stevia or aspartame did not. All four nonnutritive sweeteners altered the gut microbiome. A subsequent mouse study using fecal transplants from the study participants suggested that glycemic responses were related to changes in the gut microbiome.
