1 . Drinking your daily cup of coffee may help to lower your risk of stroke（中风）and heart disease, according to a latest research. Researchers at the Heart and Vascular Centre, Budapest, Hungary have found that drinking up to three cups of coffee a day may help protect your cardiovascular（心血管的）system.
The team studied data from nearly 500,000 people registered in the UK Biobank with an average age of 56 and no signs of heart disease at the time of recruitment. They divided them into three categories according to their coffee drinking habits: non-drinkers, up to three-cup-a-day drinkers, and more than three-cup-a-day drinkers.
Considering influencing factors such as age, sex, weight height, physical activity, blood pressure, diabetes, socioeconomic status, and usual intake of alcohol, meat, tea, fruit and vegetables, they found that three-cup-a-day drinkers had a 12 per cent lower risk of death from all causes, a 17 per cent lower risk of death from cardiovascular disease, and a 21 per cent lower risk of stroke
"To our knowledge, this is the largest study to systematically assess the cardiovascular effects of regular coffee consumption in a population without diagnosed heart disease," said study author Dr Judit Simon.
To further investigate the effect, the researchers used data from more than 30, 000 partic-ipants in the UK Biobank who had undergone MRI（核磁共振成像）scans to determine the structure and functioning capacity of their hearts.
Dr Judit Simon said, "The imaging analysis indicated that compared with participants who did not drink coffee regularly, daily coffee consumers had healthier sized and better func-tioning hearts. Our findings suggest that coffee consumption of up to three cups per day is associated with favourable cardiovascular outcomes. While further studies are needed to explain the underlying mechanisms, the observed benefits might be partly explained by positive changes in cardiac structure and function. "
