Harvard Medical School has more on the health benefits of tea.
The researchers gathered data from standardized questionnaires from the China-PAR Project, which included information on tea consumption. Now, there are more reasons to drink green tea, as scientists found consuming tea at least three times a week could help reduce the risk of premature death, living a longer and healthier life. For instance, the analyses estimated that 50-year-old routine tea drinkers would develop coronary coronary heart illness and stroke 1.41 years later and reside 1.26 years longer than those that by no means or seldom drank tea. The average duration between the two surveys was 8.2 years, and the median follow-up after the second survey was 5.3 years.
By the end, the researchers found that regular tea drinks had a 20 percent lower risk of suffering from heart disease or stroke, and a 22 percent lower risk of dying from heart disease and stroke.
Regular drinkers were those who consumed tea three or more times or week - any less and people were considered non-drinkers. Mechanism studies have suggested that the main bioactive compounds in tea, namely polyphenols, are not stored in the body long-term.More news: Ring says it fired four employees for improperly accessing customers' video footage
"Thus, frequent tea intake over an extended period may be necessary for the cardioprotective effect", Gu added. This difference in the benefits that you can get from varying types of teas is because of the difference in their making and ingredients.
Smoking, drinking, physical activity, diet and other potential confounding factors were accounted for and not likely to have biased the results, says the study's senior author, Dr. Dongfeng Gu, an epidemiologist at Fuwai Hospital in Beijing and member of the Chinese Academy of Medical Sciences. Research in the United States has found that tea drinkers - all types of tea - generally have healthier diets than non-drinkers, said Whitney Linsenmeyer, an assistant professor of nutrition at Saint Louis University.
The study did not look specifically at green tea, but only eight per cent of people in the experiment drank black tea and that had no significant health benefits, it said. "The favorable health effects are the most robust for green tea and for long-term habitual tea drinkers".
The Chinese researchers said past evidence has suggested polyphenols can protect against heart disease, high blood pressure and high cholesterol. Black tea, unlike green tea, is fully fermented, which oxidizes polyphenols and may lead to the loss of their antioxidant qualities.More news: Neil Peart, the drummer and lyricist of Rush, has died at 67
Routine tea consumption was related to extra wholesome years of life and longer life expectancy.
Compared with non-habitual tea drinkers or people who never drink tea, the hazard ratio and 95 percent 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.
These numbers pointed to a link between greater levels of tea consumption and reduced risks of atherosclerotic cardiovascular disease and all-cause mortality.
The findings were published online January 9 in the European Journal of Preventive Cardiology. 2019. doi:10.1177/2047487319894685.More news: Iran's supreme leader says missile attacks were slap in face for US
