Junk food, 指那些没营养的垃圾食物。

美国第一夫人米歇尔.奥巴马呼吁食品工业多生产健康食品。 "She urged the major food makers to produce more healthy food, rather than junk food, for children," 她要求那些大食品生产公司多为儿童生产健康食物，而不是垃圾食物。

在美国， "Some cities have banned junk food in school vending machines," 一些城市已经禁止在学校的自动售货机里卖垃圾食物。还有研究显示， "Taxing high-fat and sugary junk-food is an effective way to fight obesity," 对高脂肪、高糖分的垃圾食物征税有助于打击肥胖。

Junk food你学会了么？
