The Claim

Higher intake of acesulfame potassium is associated with a 40% increased risk of coronary heart disease (hazard ratio 1.40, 95% CI: 1.06–1.84), and higher intake of sucralose is associated with a 31% increased risk of coronary heart disease (hazard ratio 1.31, 95% CI: 1.00–1.71), indicating differential associations between these artificial sweeteners and coronary heart disease risk compared to aspartame.

In plain English

People who consume more acesulfame potassium or sucralose have a higher rate of coronary heart disease compared to those who consume less, and this association differs from the pattern seen with aspartame.

See the scientific wording

Higher intake of acesulfame potassium is associated with a 40% increased risk of coronary heart disease, with a hazard ratio of 1.40 (95% CI: 1.06–1.84), and sucralose is associated with a 31% increased risk (HR 1.31, 95% CI: 1.00–1.71), suggesting these sweeteners may have distinct effects on heart artery health compared to aspartame.

Why this might work

When people consume acesulfame potassium or sucralose, the chemicals change the balance of bacteria in the gut. This imbalance causes the gut lining to become more permeable, allowing bacterial toxins to enter the bloodstream. These toxins trigger widespread inflammation, which damages the inner lining of blood vessels and makes them less able to relax, leading to hardened arteries and increased risk of heart blockages.

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

    This big study found that people who ate or drank more of these artificial sweeteners—acesulfame potassium and sucralose—were more likely to have heart problems like blocked arteries, compared to those who didn’t consume them. It’s like they found a pattern: more sweetener, higher heart risk.
