导语：均衡的饮食胜于一切补品。
A Balanced Diet Is Better than Vitamin Pills
Nowadays, more and more people are taking vitamin supplements¹ for their health. However, the fact is that few people actually need them, according to a British expert, Dr Jane Clarke. She argues that the best way to stay healthy is keeping a balanced diet.
People are often persuaded to buy pills because they're worried that food has fewer nutrients² than it used to. They think the best source of vitamins is freshly picked produce³, and that everybody should grow their own fruit and vegetables and get them straight from the garden. However, people mainly rely on supermarket food that has been kept sometimes for months, and transported great distances.
But Clarke says, “Provided⁴ you have a balanced diet, including five portions⁵ of fruit or vegetables a day, your body doesn't need extra help from a supplement.”
“The fact is that you get far more vitamins from food than from a pill, because the body absorbs food better,” she adds.
So really, it's better just to have a balanced diet than to rely on pills. And as long as you're getting at least one portion of oily fish a week, you don't need a fish-oil supplement either.
That's not to say there's anything wrong with taking a supplement. But what does harm to people is that it's so easy to take much more than the suggested amount.

均衡的饮食胜于维生素片
目前，越来越多的人为了健康补充维生素。可是，据英国专家简·克拉克博士称，事实上没有几个人真正需要它们。她认为保持健康的最佳方式就是维持饮食平衡。
因为担心食物里面不像过去那样含有那么多的营养成分了，人们经常被说服买一些药片(作为补充)。他们认为最好的维生素来源是新采摘的农产品，并且每个人都应该种点自己直接从园子里采摘的水果和蔬菜。然而今天人们主要依赖的是超市食品，这些食品有时被保存了数月，运输了很远的距离。
但是克拉克说：“如果你膳食均衡，包括一天摄入5份水果和蔬菜，那么你的身体就不需要额外的补充了。”
“事实上你从食物中获得的维生素要比从药片中多很多，因为我们的身体吸收食物的效果更好，”她补充说。
所以，说实在的，我们最好要平衡饮食而不要依赖于维生素片。只要你一周摄入至少一份油性鱼，你就不需要鱼油的补充。
这并不是说服用补充剂有什么不对，但是超出建议量的摄取也是对人们的健康有害的，而这种情况是很容易发生的。
