Non-caloric artificial sweeteners (NAS), widely used food additives considered to be safe and beneficial alternatives to sugars, are shown here to lead to the development of glucose intolerance through compositional and functional changes in the gut microbiota of mice, and the deleterious metabolic effects are transferred to germ-free mice by faecal transplant; NAS-induced dysbiosis and glucose intolerance are also demonstrated in healthy human subjects.
