BEIJING – A study involving 100,902 Chinese adults found an association between tea consumption and reduced risks of atherosclerotic cardiovascular disease and all-cause mortality, especially among consistent, habitual tea drinkers.
Habitual tea drinkers, meaning those who drank tea three or more times per week, had 1.41 years longer of years free of atherosclerotic cardiovascular disease and 1.26 years longer of life expectancy at the index age of 50 years, according to the study that appeared online Jan. 8 in The European Journal of Preventive Cardiology. The hazard ratios among habitual tea drinkers, when compared with never or non-habitual tea drinkers, were 0.80 for atherosclerotic cardiovascular disease incidence, 0.78 for atherosclerotic cardiovascular disease mortality and 0.85 for all-cause mortality.
