一、课文背景知识 随着社会的不断进步,人们对吃什么以及怎么吃也越来越讲究。
过去，人们主要的奋斗目标是一天三餐饭能吃饱就不错了。
现在，人们不仅吃主食而且还吃零食以补充所需的养料。
十多年以前，人们争着在街上买肥肉，然而，今天街上的肥肉没人要，因为肉制品多了，因为生活水平提高了，更因为人们更加了解了体内所需的营养物质。
人们开始选择健康的食品。
如果我们要跟上现代生活的步伐，我们最好学会正确的选择吃什么以及怎么吃。
商店的事物各种各样，我们不得不进行多项选择。
当我们选择我们想要买和想要吃的东西的时候，我们最好想一想这些食物是否提供了我们所需的营养。
但是，事实上，我们做出的选择不仅是营养方面的。
许多人今天的饮食习惯是信什么吃什么。
饮食习惯成了我们信仰中不可分割的部分：素食主义者有的认为不吃肉身体要更健康些，有的则是不主张杀动物为食者。
另外一些严守素食主义者则根本不吃动物制品，甚至连酸奶酪和鸡蛋都不吃。
我们对产品作出的选择还决定于生产和加工方式，要是环保性的或者说是生态性的食物，是厂家用绿色而有清洁的方式生产出来的食物。
有机蔬菜是指生长过程中没有使用对人体和环境有害的化学药品的蔬菜。
因为我们有如此多的东西供选择，因此许多商家对我们吃什么就提出 了一些建议。
书刊杂志和电视媒体向我们介绍不同保健类型需要的食物和药品，然1。
