Artificial sweetener-induced dysbiosis and associated molecular signatures.

Despite their approval for inclusion in beverages, and food products, the safety of artificial sweeteners is still a topic of debate within the scientific community. A significant aspect of this debate focuses on the potential of artificial sweeteners to induce dysbiosis, an imbalance in the intestinal microbiota, which has been associated with many diseases including obesity, Type 2 diabetes, and cardiovascular diseases. The interactions and mechanisms of action of artificial sweeteners within the gut microbiota, as well as the extent of associated molecular alterations, are still under active investigation. This review aims to evaluate recent developments in artificial sweetener-induced dysbiosis with its associated molecular signatures. Importantly, potential future directions for research are proposed, offering insights that could guide further targeted studies and inform dietary recommendations and policy revisions.
