The Claim

Substituting artificial sweeteners for added sugars has no effect on the risk of cardiovascular disease in the general population, with a hazard ratio of 1.00 (95% CI: 0.99–1.01).

Replacing added sugars with artificial sweeteners does not change the risk of developing cardiovascular disease in the general population.

See the scientific wording

Substituting artificial sweeteners for added sugars does not reduce the risk of cardiovascular disease, with a hazard ratio of 1.00 (95% CI: 0.99–1.01), indicating that replacing sugar with artificial sweeteners offers no cardiovascular benefit in the general population.

Why this might work

When people replace sugar with artificial sweeteners, their bodies still respond as if sugar is present, which keeps blood sugar levels unstable and damages blood vessel lining. This prevents any improvement in heart health.

  1. Study: Artificial sweeteners and risk of cardiovascular diseases: results from the prospective NutriNet-Santé cohort

    This study found that people who ate or drank more artificial sweeteners had a higher chance of having heart problems or strokes, not lower. So switching from sugar to artificial sweeteners might not help your heart — it could even hurt it.
