The Claim

Among 105,588 French adults, sucralose intake above the sex-specific median is associated with a 34% higher risk of developing type 2 diabetes over a 9.1-year follow-up period, with reduced effect size in sensitivity analyses and when modeled as a continuous variable.

In plain English

In a study of over 105,000 French adults, those who consumed more sucralose than the median amount for their sex had a 34% higher rate of developing type 2 diabetes over 9.1 years, though the strength of this link decreased in some statistical tests.

See the scientific wording

Sucralose intake above the sex-specific median is associated with a 34% higher risk of developing type 2 diabetes over 9.1 years in a cohort of 105,588 French adults, though this association was less robust in sensitivity analyses and weakened when modeled as a continuous variable.

Why this might work

When sucralose is consumed, it changes the bacteria in the gut, which leads to the production of chemicals that interfere with how the body handles sugar. This causes the pancreas to release less insulin and makes the body less able to clear sugar from the blood, eventually leading to high blood sugar and type 2 diabetes.

    People who drank a lot of diet soda with sucralose were more likely to get type 2 diabetes over 9 years, even after accounting for weight and other factors — though the link wasn’t as strong as with other sweeteners.
