Drinking tea at least three times a week could increase your chances of living longer, according to a new Chinese study by researchers at the Chinese Academy of Medical Sciences. The study found that people who habitually drink tea were more likely to have a longer life expectancy. Researchers estimated that 50-year-old habitual tea drinkers would develop coronary heart disease and stroke 1.41 years later than other people, as Yahoo News details:
they found that those who maintained their regular tea consumption at both surveys had a 39 percent lower risk of incident heart disease and stroke, 56 percent lower risk of fatal heart disease and stroke, and 29 percent decreased risk of all-cause death, compared to consistent never or non-habitual tea drinkers.
"The protective effects of tea were most pronounced among the consistent habitual tea drinking group," said senior author Dr. Dongfeng Gu. "Mechanism studies have suggested that the main bioactive compounds in tea, namely polyphenols, are not stored in the body long-term. Thus, frequent tea intake over an extended period may be necessary for the cardioprotective effect."
The findings also suggest that drinking green tea was linked with around a 25 percent lower risk of incident heart disease and stroke, fatal heart disease and stroke, and all-cause death, however, no significant associations were found for black tea.
Dr. Gu points out that a preference for green tea is unique to East Asia. "In our study population, 49 percent of habitual tea drinkers consumed green tea most frequently, while only 8 percent preferred black tea. The small proportion of habitual black tea drinkers might make it more difficult to observe robust associations, but our findings hint at a differential effect between tea types."
