I keep reading about how the obesity epidemic is happening because people eat way more than they used to. That seems to make sense, but is it right? Well, it's certainly true that food is more available than it used to be, at least in the United States. It's also the case that Americans eat out more than they used to, and that restaurant portion sizes have gotten bigger. But it's complicated. There's certainly evidence that people eat more today than they did several decades ago. One study claims that we eat nearly 600 more calories per day than people did in the mid 1970s. At least one other study, though, claims that Americans actually don't eat substantially more now than we used to. Even though restaurant portion sizes are bigger, it's possible that people are compensating by eating less in other ways.
我一直在阅读一些有关人们因食用比以前过多食物而导致肥胖的有关报告。这看似有理，但是真的正确吗？ 食物比以前更容易获得是非常肯定的，至少在美国是这样。这也是美国人比以前吃的多的原因，并使得饭店的面积越来越大。 但是这是复杂的事情。有明确的证据表明人们现在比几十年前吃更多的食物。一项研究称我们每天食用食物比二十世纪七十年代几乎多600卡路里。 至少有一项研究称美国人实际上所食用的食物并不比以前多。即使饭店的面积越来越大，但是人们可能通过其他途径所食用的食物较少。
