Do artificial sweeteners increase the risk of diabetes and metabolic disease, or are they a safe alternative to sugar?
Full answer body
Expanded summary
Research on artificial sweeteners and their impact on diabetes risk is mixed. Some studies, such as a meta-analysis of 17 cohorts with 38,253 cases, suggest that artificial sweeteners are associated with a higher risk of type 2 diabetes. However, regulatory reviews and controlled trials generally conclude that artificial sweeteners are safe and may be preferable to sugar for calorie reduction. Limitations include gaps in long-term evidence and differences between sweeteners. The evidence base is substantial but conflicting, with some suggesting potential risks and others supporting safety.
