What the research says

3 studies

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

    The study looked at people who eat or drink things with zero-calorie sweeteners and found they had a higher chance of heart problems, including heart attacks. This supports the idea that these sweeteners might increase heart attack risk.

  2. Study: High consumption of artificially sweetened beverages and associated risk of cardiovascular events: A systematic review and meta-analysis.

    The study looked at people who drink a lot of diet sodas and found they have a higher chance of dying from heart problems or having a stroke, which supports the idea that some zero-calorie sweeteners might harm heart health.
