Passage Two

对话2

Highly processed foods—the kinds made with lots of sugar, fat and salt—make up as much as sixty percent of the average American diet,

深加工食品，也就是大量糖、脂肪和盐制作而成的食品，占普通美国人日常饮食的 60% 之多，

but a new study shows that their low price and convenience come at a cost to health.

但一项新研究表明，这类食品价格低廉、食用便捷的背后，是以损害健康为代价的。

The study found that when people ate a highly processed diet, they consumed about five hundred more calories per day than they did when they ate a less processed diet.

该研究发现，当人们长期吃深加工食品时，每日摄入的热量比食用少加工食品时多出约 500 大卡。

They also gained two pounds over two weeks even though both diets had the same amounts of nutrients like sugar, fat, fiber and salt.

即便两种饮食方案中糖、脂肪、膳食纤维、盐等营养成分含量相同，受试者两周内体重依旧上涨了两磅。

It wasn’t a shock to find highly processed foods weren’t healthy.

深加工食品并不健康，这一结论并不出人意料。

Other research has linked them to a higher risk of cancer and obesity.

其他研究发现，深加工食品会提升癌症与肥胖的患病风险。

What was unexpected was that sugar, fat and salt didn’t seem to be what caused people to overeat.

令人意外的是，导致人们暴饮暴食的元凶似乎并不是糖、脂肪与盐。

This is the first trial that demonstrates that there is something about highly processed foods independent of those nutrients that causes people to overeat.

这是首个证实：深加工食品中存在除上述营养素之外的某种物质，会促使人们过量进食的试验。

The study also found that when eating a highly processed diet, people ate faster.

该研究还发现，人们在吃深加工食品时进食速度更快。

This could be one reason why they gained more weight.

这或许是他们体重增长更多的原因之一。

Highly processed food tends to be softer, which makes it easier to chew and swallow.

深加工食品通常质地更松软，咀嚼和吞咽起来更加容易。

One theory is that if you’re eating more quickly, you’re not giving your gut enough time to signal to your brain that you’ve had enough calories and that you’re full.

有一种理论认为：进食速度过快时，肠胃没有充足时间向大脑传递热量充足、已经饱腹的信号。

By the time the brain gets that signal, you’ve already overeaten.

等大脑接收到饱腹信号时，你已经吃多了。
