Summary

This study looks at whether drinking a beverage with artificial sweeteners (erythritol or xylitol) changes how blood platelets clump together, which could affect heart attack or stroke risk. Researchers will measure platelet activity and blood levels of these sweeteners in 50 healthy adults before and after consumption. The goal is to understand if these common sugar substitutes might increase cardiovascular risk.
