Does the consumption of artificial sweeteners as a replacement for sugar increase the risk of diabetes or hyperinsulinemia? Have there been any clinical trials studying this?

1 Answer 1



There is a strong link between the consumption of sugar-sweetened beverages (SSB), obesity, and Type 2 diabetes, recognized by multiple studies, for example this survey (1).

This article (2) compares the consumption of SSBs with that of artificially sweetened beverages, and finds SSBs significantly worse. The study, however, is only a 10-week study.

This article (3) shows that one dose of sucralose does not cause insulin production.

This article (4) tends to show that ongoing use of artificial sweeteners does not control weight, but it is not conclusive evidence that it causes an increase in weight (self-selection issue).

This article (5), however, discusses a cohort where higher consumption of diet soda is associated with a significant increase of the risk of metabolic syndrome and the development of T2 diabetes. It is not, however, a smoking gun, because it does not prove causality but association (there could be self-selection: people at risk for metabolic syndrome may tend to drink more diet soda).


I would say that there is weak evidence of an association between the consumption of artificial sweeteners and diabetes risk. There is also some evidence that using artificial sweeteners is better than SSBs. On the whole, it seems to me that evidence is mixed at this stage.

For myself, I will continue -- carefully -- to use artificial sweeteners (sucralose in my case), but I will keep an eye on additional evidence when it comes up.

    If you agree with Narusan's edit you can click on "review" at the top of the page and approve the edit. Otherwise it needs approval of two high-rep users (I have approved it but it needs one more). This is required by the SE system - certain "privileges" such as editing a question, require a certain amount of reputation points.
