The world is full of tea drinkers. For many, they simply enjoy the taste. But new research suggests tea might help those who drink it live longer than those who do not. Tea is known to contain helpful substances known to reduce inflammation. Past studies in China and Japan, where green tea is popular, have suggested several health benefits. Now, scientists say black tea may show similar benefits. Scientists from the United States National Cancer Institute carried out the study. They examined years of data gathered about the tea drinking behavior of almost 500,000 adults in Britain for as many as 14 years. Black tea is the most common kind of tea in Britain. The researchers adjusted for risks that individual may have related to health, living conditions, diet and lifestyle choices, as well as age, race and gender. The 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.
