Americans spend more than $20 billion a year on supplements in hopes of staving off cancer, heart disease, and dementia. Trouble is, the latest research shows they provide no benefit — and they may even be hazardous to our health. But given our nutrient-deprived diets, should we really stop taking these pills altogether? 美国人每年买补品花费超过200亿美元，希望能避免癌症、心脏病和痴呆症。麻烦的是，最新研究表明它们没任何好处——甚至可能对我们的健康有害。但鉴于我们饮食营养不均衡，我们真的要完全停止服用这些营养片吗？ These are the startling findings of three articles just published in the highly influential Annals of Internal Medicine. 下面是刚发表在影响力颇高的《内科医学年鉴》上的三篇文章的惊人发现。 The researchers involved in the studies didn't mince words; they're concerned that people are spending too much money on pills that confer no benefit, and in some cases may even be harmful. What's more, they even hinted that companies selling supplements are fueling health anxieties to offer unnecessary cures. 参与研究的人员不拐弯抹角说话，他们担心人们花了很多钱在没有好处、而且某些情况下甚至会有害的药片上。更重要的是，他们还暗示公司销售补品正在助长大家对健康的焦虑，从而可以提供不必要的治疗。 |
