Overview
- Researchers analysed 485,934 adults over about nine years and recorded 14,863 vascular events in the Journal of Internal Medicine study.
- Overall habitual tea drinkers had an estimated 11% lower risk of vascular disease compared with non‑drinkers according to the analysis.
- The associations varied: black tea and moderate‑strength brews showed the most consistent inverse links and the lowest estimated risk was near 6–8 cups a day among weekly drinkers.
- Drinking very hot or “burning hot” tea was linked with higher vascular risk in the study, but the authors say the result does not prove heat caused the increase.
- The paper is observational and used one self‑reported measure of tea habits with no standard cup size or exact temperatures, so experts urge caution, replication and focus on overall diet, not single foods.
