50岁以上的人最好每天能吃一个苹果 If everyone over the age of 50 ate an apple a day, 8,500 deaths from heart attacks and strokes could be avoided every year in the UK, say researchers. 英国研究人员称，如果国内超过50岁的人每天吃一个苹果，每年死于心脏病和中风的人将减少8500。 ? Apples would give a similar boost to cardiovascular health as medicines, such as statins（他汀类）, yet carry none of the side-effects, the University of Oxford researchers say in the BMJ.? ? They base their assumptions on modelling, not direct scientific study.? ? Any fruit should work, but getting people to comply could be challenging. ? More than two-thirds of adults do not eat the recommended five portions of fruit and veg a day, population surveys suggest.? ? And although nine in 10 of us do manage to eat at least one portion a day, Dr Adam Briggs and colleagues, from the British Heart Foundation Health Promotion Research Group at Oxford University, say we would all benefit from eating more. ? By their calculations, if adults of all ages could manage to eat an extra portion of fruit or veg a day, as many as 11,000 vascular deaths could be averted each year. ? The Victorian mantra of an apple a day to keep the doctor away is particularly important for the over-50s, who are at increased risk of vascular diseases, say the researchers. ? They analysed the effect on the most common causes of vascular mortality - heart attacks and strokes - of prescribing either a statin a day, which lowers cholesterol, or an apple a day to people over 50. ? Assuming at least seven in every 10 complied with the advice, statin drugs could save 9,400 lives and an apple a day 8,500 lives a year, they calculate.? ? The data their work rests on comprises a large body of medical trials and observations involving hundreds of thousands of patients. ? Dr Briggs said: The Victorians had it about right when they came up with their brilliantly clear and simple public health advice, An apple a day keeps the doctor away? ? It just shows how effective small changes in diet can be, and tha
