The Claim

Higher intake of artificial sweeteners, exceeding 16.4 mg/day in men and 18.5 mg/day in women, is associated with a 69% increased risk of developing type 2 diabetes over a median follow-up of 9.1 years in a large French adult cohort of 105,588 individuals, even after adjusting for weight change, dietary patterns, and other metabolic risk factors.

In plain English

Adults who consume more than 16.4 mg/day of artificial sweeteners if male or 18.5 mg/day if female have a 69% higher incidence of type 2 diabetes over 9.1 years compared to those who consume less, after accounting for weight change, diet, and other metabolic risk factors.

See the scientific wording

Higher intake of artificial sweeteners, exceeding 16.4 mg/day in men and 18.5 mg/day in women, is associated with a 69% increased risk of developing type 2 diabetes over a median follow-up of 9.1 years in a large French adult cohort of 105,588 individuals, even after adjusting for weight change, dietary patterns, and other metabolic risk factors.

Why this might work

Artificial sweeteners change the bacteria in the gut, which leads to the production of chemicals that interfere with how the body uses sugar. This causes the pancreas to release less insulin and makes the body less able to control blood sugar, eventually leading to high blood sugar and type 2 diabetes.

What the research says

2 studies
  1. Study: Artificial Sweeteners and Risk of Type 2 Diabetes in the Prospective NutriNet-Santé Cohort

    People who drank more diet soda or ate more foods with artificial sweeteners than a certain amount each day were much more likely to get type 2 diabetes later, even when scientists accounted for how much they weighed or what else they ate.

  2. Study: Artificial Sweeteners and Risk of Type 2 Diabetes in the Prospective NutriNet-Santé Cohort

    People who drink more than about one-third of a diet soda a day were found to be almost twice as likely to develop type 2 diabetes over the next decade, even if they didn’t gain weight or eat poorly. This suggests artificial sweeteners might not be as harmless as we thought.
