垃圾食物真正的定义指的仅仅是提供一些热量，
别无其他营养素的食物。或是提供超过人体需求，
变成多余成分的食品。
如：罐头、酱菜中的盐分常常会造成过多的钠
滞留体内，成为多余的垃圾。
传统小吃就有不少垃圾食物的存在，如葱油饼、
油炸饼、奶油饼，早餐常吃的油条、烧饼，
或是许多人通宵熬夜会吃的泡面，这些东西都是只含有油脂与面粉，没有其他太多的营养素，
只纯粹提供了热量，都是地道的中国口味
的垃圾食物。
????
(junk food)罐头食品，大多提供盐分与其他调味剂如人工香料、防腐剂等，没有太多其他的营养成分在内。
???? ???? 汽水、可乐、巧克力、口香糖、糖果主要由糖、
色素、香料所组成的，除提供糖分热量之外没有
什么其他的营养价值。 ???? ???? 油炸薯条、洋芋片、各式的饼干等休闲食品，
也是一堆面粉加油制成，除提供了淀粉和油的热量之外，没有太多营养成分在其中。
所以，大家为了自己的身体，尽量少吃和不吃这些垃圾食品 你妈妈很健康吗 ?
