在7月21日这一天，有些人也许会放弃他们的日常饮食，不带任何愧疚感地尽情享用所有最喜欢的不健康零食，因为这天是垃圾食品日。

垃圾食品是指含有大量卡路里但很少有或没有营养价值的食物。但通常情况下，它们都很美味！20世纪50年代，这个词在美国流行起来，被广泛用来指代那些深加工、含有大量糖、脂肪和鹽的食物。

研究表明，偶尔吃垃圾食品对健康没有负面影响——只有当一个人经常吃垃圾食品时，他们的饮食才会被认为是不健康的。食用大量被认为是垃圾食品的食物会导致一些健康问题，包括患肥胖、糖尿病和心脏病的高风险。

垃圾食品是什么时候开始进入我们的生活的？这个时间与整个20世纪末包装食品出现的时间是一致的。当然，在几十年的时间里，家常菜仍然是标准饮食。然而，二战结束后，垃圾食品真的开始走红。
