London - Tea really is the best drink of the day – it can cut your risk of dying prematurely, say researchers.
A study shows that drinking tea reduces the risk of dying from causes unrelated to the heart by a quarter compared with those who don’t drink tea.
Experts say it is better for you than coffee, although habitual coffee drinkers tend to be more unhealthy and smokers.
The benefits of tea are largely due to the flavonoid content, antioxidant ingredients that are thought to be good for the heart.
Study leader Professor Nicolas Danchin said previous research showed “divergent” effects of tea and coffee on heart health.
He added, however: “If you have to choose between tea or coffee it’s probably better to drink tea.”
The study involved 131 401 people aged 18 to 95 at low risk of cardiovascular diseases attending the Paris IPC Preventive Medicine Centre between January 2001 and December 2008.
There were 95 deaths from cardiovascular (CV) causes and 632 deaths from non-CV causes.
Coffee or tea consumption was assessed by a questionnaire and classified as: none, one to four cups per day, or more than four cups. The researchers found that coffee drinkers had a higher CV risk profile than non-drinkers, particularly for smoking, with 57 percent of those drinking more than four cups per day being smokers.
Non-coffee drinkers were more physically active, with 45 percent having a good level of physical activity compared with 41 percent of the heavy coffee drinkers.
“This is highly significant in our large population,” Prof Danchin said at the European Society for Cardiology meeting in Barcelona. Tea had a marked effect on blood pressure, with a significant reduction in the heavy tea drinkers, compared with non-drinkers.
Professor Danchin said: “Overall we tend to have a higher [CV] risk profile for coffee drinkers and a lower risk profile for tea drinkers. We also found big gender differences.
“Men tend to drink coffee much more than women, while women tend to drink more tea than men.” There was a trend for tea drinking to lower cardiovascular deaths but the effect was not statistically significant after adjusting for age, gender and smoking.
But tea lowered the risk of non-CV death, by a quarter for tea drinkers compared with no tea at all.
The study did not define the type of tea, or whether milk was added. Participants were just asked how much tea they drank per day.
Professor Danchin, of the Hôpital Européen Georges Pompidou in Paris, said: “Tea drinking lowered the risk of non-CV death by 24 percent and the trend towards lowering CV mortality was nearly [statistically] significant.”
He added: “Interestingly, most of the effect of tea on non-CV mortality was found in current or ex-smokers, while tea had a neutral effect in non-smokers.”
Coffee significantly increased non-CV mortality but the increased risk disappeared when the effect was adjusted for smoking. - Daily Mail
