HEALTH Men who drink tea likely to develop cancer
Scientists at University of Glasgow track health of 6,000 tea-drinking men for four decades
London: Men who drink lots of tea are far more likely to develop prostate cancer, researchers have warned.
They found that those who drank seven or more cups a day had a 50 per cent higher risk of contracting the disease than men who had three or fewer.
The warning comes after scientists at the University of Glasgow tracked the health of more than 6,000 men for four decades.
Their findings run counter to previous research, which had suggested that tea-drinking lowers the risk of cancer, as well as heart disease, diabetes and Parkinson’s disease.
The study, led by Dr Kashif Shafique, began in 1970.
Participants aged between 21 and 75 were asked to complete a questionnaire about their usual consumption of tea, coffee and alcohol as well as their smoking habits and general health, and had to attend a screening examination.
Just under a quarter of the 6,016 men were heavy tea drinkers, consuming seven or more cups a day. Of these, 6.4 per cent developed prostate cancer over the next 37 years.
Researchers found that the subjects who drank the most tea were often teetotal and led healthy lifestyles.
As a result, they may have been at a lower risk of death from ‘competing causes’, effectively giving them more time to develop prostate cancer, the journal Nutrition and Cancer reports.
