Aspartame update: “Diet” and regular soda equally raise insulin levels in saliva, study suggests

10 Nov 2023 — Although it is commonly believed that artificial sweeteners like aspartame do not raise insulin levels in the same way as sugar, a new clinical trial challenges this idea. International researchers found that salivary insulin levels increased one hour after consuming a soft drink, for both regular and diet drinks — sweetened with artificial sweeteners. 

Insulin levels in saliva did not change after consuming test drinks — water or a drink with low sucrose content. Scientific research found a correlation between insulin levels in saliva and blood.
