Presentation
垃圾食品(Junk Food)，是指仅仅提供一些热量，别无其它营养素的食物，或是提供超过人体需要，变成多余成分的食品。垃圾食品包括：油炸类食品、腌制类食品、加工类肉食品（肉干、肉松、香肠、火腿等）、饼干类食品（包括所有加工饼干）、汽水可乐类饮料、方便类食品（主要指方便面和膨化食品）、罐头类食品（包括鱼肉类和水果类）、话梅蜜饯果脯类食品、冷冻甜品类食品（冰淇淋、冰棒、雪糕等）、烧烤类食品。
Background
junk food的说法来自于葡萄牙语。大约500年前，在葡萄牙语里有一个词“junk”，意思是“old pieces of rope（旧缆绳）”。天长日久，这个词的意思逐渐演变为任何可利用的废弃材料。最后，“junk”用来指价值不高或根本没有任何价值的东西。于是，人们就称没有多少营养的食物为“junk food”。
