Drinking Tea Regularly May Reduce Risk of Atherosclerotic Cardiovascular Disease
Atherosclerotic cardiovascular disease (ASCVD) occurs when cholesterol plaque builds up in the walls of the arteries, causing narrowing and hardening of the arteries. This results in blood flow obstruction, and eventually may lead to heart attack, stroke, and peripheral vascular disease. A recent study has found that people who drink tea on a regular basis may have a up to a 39% reduced risk of ASCVD.
Participants in the study included 100,902 adults who participated in the Prediction for ASCVD Risk in China study. They were followed for an average of 7.3 years, during which time all incidences of ASCVD, mortality due to ASCVD, and all-cause mortality were recorded. Questionnaires were administered at baseline and during follow-up visits to evaluate tea consumption. Participants were grouped as habitual tea drinkers (3 times or more per week) or non-habitual or never (less than 3 times per week).
The researchers found that participants in the habitual group had a 39% lower risk of ASCVD, a 56% lower risk of ASCVD mortality, and a 29% lower risk of all-cause mortality, compared to those in the non-habitual group. They also had an average 1.41 years longer before developing ASCVD, .32 years before developing coronary heart disease, and 1.23 years before developing a stroke compared to those in the non-habitual group. In addition, those in the habitual group also had an average 1.26 years longer life expectancy at the age of 50.
The study was conducted by researchers from Peking Union Medical Center. It was published online ahead of print on January 8, 2020 in the European Journal of Preventive Cardiology.
