1The world is full of tea drinkers.
2For many, they simply enjoy the taste.
3But new research suggests tea might help those who drink it live longer than those who do not.
4Tea is known to contain helpful substances known to reduce inflammation.
5Past studies in China and Japan, where green tea is popular, have suggested several health benefits.
6Now, scientists say black tea may show similar benefits.
7Scientists from the United States National Cancer Institute carried out the study.
8They examined years of data gathered about the tea drinking behavior of almost 500,000 adults in Britain for as many as 14 years.
9Black tea is the most common kind of tea in Britain.
10The researchers adjusted for risks that individual may have related to health, living conditions, diet and lifestyle choices, as well as age, race and gender.
11The study found that high tea intake - two or more cups a day - was linked to a moderate benefit: a nine to 13 percent lower risk of death from any cause than non-tea drinkers.
12The research was published in Annals of Internal Medicine.
13The scientists say the lowered risk of death held true for study subjects with heart disease.
14However, researchers said there was no clear finding in connection with deaths from cancer.
15Researchers were not sure why.
16But, it is possible there were too few confirmed cancer deaths to measure, said Maki Inoue-Choi, who led the study.
17All kinds of tea-green, black, oolong, and white-are produced from the Camellia sinensis plant using different methods.
18Tea contains various elements, including polyphenols.
19Experts at the U.S. National Institutes of Health say polyphenols are thought to be responsible for the health benefits that have traditionally been linked to tea, especially green tea.
20Green tea is reported to improve mental ability, ease digestive problems and head pain, and help people with weight loss.
21Green tea has also been studied for possible protective effects against heart disease and cancer.
22The study of British tea drinkers was based on observing people's behaviors and health.
23This kind of methodology cannot prove cause and effect.
24"Observational studies like this always raise the question: Is there something else about tea drinkers that makes them healthier?" said Marion Nestle.
25She is a professor of food studies at New York University.
26The study does not offer enough evidence to advise people to change their tea behaviors, said Inoue-Choi.
27"If you drink one cup a day already, I think that is good," she said. "And please enjoy your cup of tea."
