60秒科学:Apple A Day Could Keep Statins Away


60秒科学节目(SSS)是科学美国人网站的一套广播栏目,英文名称:Scientific American – 60 Second Science,节目内容以科学报道为主,节目仅一分钟的时间,主要对当今的科学技术新发展作以简明、通俗的介绍,对于科学的发展如何影响人们的生活环境、健康状况及科学技术,提供了大量简明易懂的阐释。

“An apple a day keeps the doctor away.” Especially the cardiologist, as it turns out. Because an apple a day might save as many lives as cholesterol-lowering statins are thought to. So says a study in the British Medical Journal. [Adam DM Briggs, Anja Mizdrak and Peter Scarborough, A statin a day keeps the doctor away: comparative proverb assessment modelling study]

Using mathematical models, researchers added an apple to the diet of every Brit over the age of 50—a total of 22 million adults—while keeping calorie intake constant. The idea being that calories from a vitamin and fiber-packed apple might displace those from less salubrious snacks.

And they found that upping the apple input could stave off some 8,500 deaths by heart attack or stroke each year—compared with an estimated 9,400 deaths averted by statins in England.

The comparison is not apples-and-oranges. Because some doctors have indeed proposed giving statins to everyone over 50 as a preventive measure. But a small change in diet might do as much good, if people comply. And unlike statins, which can up the risk of diabetes, apples have few side effects: the researchers cite the distress caused by a bruised apple; or the “theoretical risk of identifying half a worm inside.”

So how do you like them apples?
