Tea drinkers enjoy possible health benefits, study suggests

A cup of tea just got a bit more relaxing.
Tea can be part of a healthy diet and people who drink tea may even be a little more likely to live longer than those who donít, according to a large study.
Tea contains helpful substances known to reduce inflammation. Past studies in China and Japan, where green tea is popular, suggested health benefits. The new study extends the good news to the U.K.ís favorite drink: black tea.
Scientists from the U.S. National Cancer Institute used a large database project that asked about the tea habits of nearly a half million adults in the United Kingdom, then followed them for up to 14 years. They adjusted for risk factors such as health, socioeconomics, smoking, alcohol intake, diet, age, race, and gender.
Higher tea intake ó two or more cups daily ó was linked to a modest benefit: a 9% to 13% lower risk of death from any cause vs. non-tea drinkers. Tea temperature, or adding milk or sugar, didnít change the results.
The study, published in Annals of Internal Medicine, found the association held up for heart disease deaths, but there was no clear trend for cancer deaths. Researchers werenít sure why, but itís possible there werenít enough cancer deaths for any effect to show up, said Maki Inoue-Choi, who led the study.
A study like this, based on observing peopleís habits and health, canít prove cause and effect.
"Observational studies like this always raise the question: Is there something else about tea drinkers that makes them healthier?" said Marion Nestle, a professor of food studies at New York University. "I like tea. Itís great to drink. But a cautious interpretation seems like a good idea."
Thereís not enough evidence to advise changing tea habits, said Inoue-Choi.
"If you drink one cup a day already, I think that is good," she said. "And please enjoy your cup of tea."
