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。
垃圾食品日是犒劳自己的绝佳时机。在垃圾食品日，你可以吃任何想吃的东西。然而，接下来的一天，你要恢复到健康的饮食。
不同的文化对垃圾食品有自己不同的定义——在一种文化中可能是垃圾食品的食物，在另一种文化中可能被认为是营养食品。许多人认为快餐通常来说是垃圾食品，然而有些快餐是以健康的方式制作的，而且可能很有营养。
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。
人们旅行的情况越来越多，外出吃饭的情况也越来越多，这使快餐连锁店和冷冻食品真正流行起来。有很多不同的食物可供人们选择。然而，直到20世纪70年代，垃圾食品才开始有了一个坏名声。
从那时起，就有了更多关于垃圾食品的知识和信息。许多食品制造商都试图制作出我们最喜欢的垃圾食品的健康版本！如果你偶尔吃吃垃圾食品，然而通常保持健康的饮食习惯，它们应该不会对你造成任何伤害！
