according to the British Daily Mail, University of Glasgow, UK Researchers, who studied more than 6000 men for 37 years, showed that people who drank more than 7 cups of tea a day increased the risk of prostate cancer by 50% more than those who drank 3 cups of tea a day. Their findings are contrary to previous studies suggesting that drinking tea can reduce the risk of cancer, heart disease, diabetes and Parkinson's disease.
Kashif Shafiq (Kashif Shafique) began the study in 1970, when participants were asked to complete a questionnaire of tea, coffee and wine between the ages of 21 and 75, and of course smoking habits and health conditions. At that time, only 6016 people, less than 1/4, had more than 7 cups of tea a day. Of these people, 6.4% of them developed prostate cancer in the next 37 years.
researchers found that people who drink a lot of tea are usually completely abstinence, and have a healthier lifestyle and may be more likely to live longer, so they are more likely to develop prostate cancer. "It's not clear that tea itself is a risk factor, or that tea drinkers are usually healthier and longer, so it's more common to develop prostate cancer," Shafiq said.
it is reported that almost 80% of people in Britain drink tea and consume 165 million cups of tea a day. British tea has an annual value of over 700 million pounds (about 7 billion yuan). In Britain, 40 thousand people suffer from prostate cancer each year, and more than 10 thousand patients die.
