The Claim
Replacing dietary sugar with artificial sweeteners has no effect on the risk of developing type 2 diabetes, as indicated by a hazard ratio of 1.13 (95% CI 0.98–1.29) in a cohort of 105,588 French adults.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Switching from sugar to artificial sweeteners in the diet does not lower the chance of developing type 2 diabetes.
See the scientific wording
Replacing dietary sugar with artificial sweeteners does not reduce the risk of developing type 2 diabetes, as substitution analyses showed no protective effect (HR 1.13 [95% CI 0.98–1.29]) in a cohort of 105,588 French adults.
Artificial sweeteners change the bacteria in the gut, which causes the body to process sugar less efficiently and reduces insulin production. At the same time, they cause fat cells to grow larger and store more fat while breaking down less fat, which makes the body less responsive to insulin. Together, these changes raise blood sugar levels over time and lead to type 2 diabetes.
What the research says
1 studyStudy: Artificial Sweeteners and Risk of Type 2 Diabetes in the Prospective NutriNet-Santé Cohort
This study found that people who ate or drank more artificial sweeteners were more likely to develop type 2 diabetes, not less — so swapping sugar for sweeteners doesn't help prevent diabetes, and might even make it worse.
