Despite numerous reports of the beneficial effects of black and green tea on human health, the role of tea consumption in the primary prevention of cardiovascular diseases (CVD) remains poorly understood.
Results of a prospective cohort study among Chinese adults showed that compared with never or non-habitual tea drinkers, the hazard ratio and 95% confidence interval among habitual tea drinkers was 0.80 (0.75–0.87), 0.78 (0.69– 0.88), and 0.85 (0.79–0.90) for atherosclerotic cardiovascular disease incidence, atherosclerotic cardiovascular disease mortality, and all-cause mortality, respectively.
In addition, the authors note that habitual tea drinkers had 1.41 years longer of atherosclerotic cardiovascular disease-free years and 1.26 years longer of life expectancy at the index age of 50 years.
More than 100.000 Chinese adults were included in the study (median follow-up of 7.3 years). Information about tea consumption was collected using standardized questionnaires. Participants in the study consumed green tea, black tea, and other types of beverages, except for those drinks that were not prepared using a tea plant (Camellia sinensis).
