What the research says

3 studies

  1. Study: Sweet Surprises: An In-depth Systematic Review of Artificial Sweeteners and Their Association with Cerebrovascular Accidents

    The study looked at people who drink diet sodas and other artificially sweetened drinks and found they have a higher chance of having a stroke, especially if they drink a lot. This supports the idea that some zero-calorie sweeteners might increase stroke risk.

  2. Study: Genetically Predicted Artificial Sweeteners and Stroke Susceptibility: A Multivariable Mendelian Randomization Study.

    The study found that people who use artificial sweeteners, especially in tea or with higher sucralose levels, may have a higher chance of certain types of stroke. This supports the idea that some zero-calorie sweeteners could increase stroke risk.
