Regular consumption of non-nutritive sweeteners (NNS) does not have conclusive evidence for beneficial or harmful effects on major health outcomes including appetite, short-term food intake, cancer risk, diabetes risk, dental caries, weight gain, or obesity in healthy subjects.
Current scientific evidence does not support the idea that non-nutritive sweeteners (like aspartame, sucralose, or stevia) are inherently harmful or beneficial for weight, cancer, or diabetes risk in healthy people. While some studies show mixed results on appetite, the overall body of research does not confirm significant health benefits or harms. You can use them as part of a balanced diet without expecting specific health outcomes based on current data.
In healthy subjects, appetite and short term food intake, risk of cancer, risk of diabetes, risk of dental caries, weight gain and risk of obesity are the most investigated health outcomes. Overall there is no conclusive evidence for beneficial and harmful effects on those outcomes.
Why this rating
Based on a scoping review of 372 studies (including RCTs and cohorts), but the conclusion is that evidence is inconclusive/inconsistent rather than definitive.
