What are the commonest foods on the American menu? Hamburgers and French fries,sugar-laden drinks;pies andwhipped cream,malts and ice-cream. Apart from an occasional broiledhamburger,all the things on that list are bad for us.And there are certain prophets of doomwho predict that all those fatladen fast foods provide us with only one thing-a faster road tothe grave.

　　On the other hand, there are those who claim that the basic fast-food meal contains all thenourishment you need. After all, there are meat. milk, salad (if you have the extras), and bread.And if you have a cheeseburger instead of a hamburger, you are doing yourself an extra favorby adding additional protein.What these good news gossips are overlooking is the usuallypulpy bun; the excess of sugar in the maltose or Coke;and overdose of salt that is sprinkledon the hamburger to make palatable (美味的).

　　So you decide to stay away from the hamburger joint, and buy your food from thesupermarket. Are you any better off? Not if you buy frozen or canned food. The experts tell usthat canned and frozen vegetables contain sugar, as well as all sorts of perspectives that arenot doing anything to improve your health. According to these people. the only way to be sureyour food is good for you is to buy it and cook it fresh. And then. of course. you have to eat it-and that creates another problem. The speed of today's world has encouraged many of us toeat far too fast. We do not chew our food enough, and we eat on the run or we jump andstart running the minutc we finish eating.

　　我們都聽說過這樣一句話：吃什么，就長成什么樣。但是有多少人愿意承認這句話不僅適用于那些不在這里的不相識的人，還適用于我們自己呢?[1]當前的調查結果表明大多數美國人的飲食習慣糟糕，而有些習慣是我們的生活方式決定的。這種生活方式迫使我們吃便宜的快餐類食品。

　　那么美國人食譜上最常見的食品有哪些呢?漢堡包和炸薯條，富糖飲料。餡餅和生奶油，麥牙和冰淇淋。除了人們偶爾一吃的烤肉漢堡包外，單子上所有的其他食物都對我們的健康不好。[2]有一些悲觀的預言家斷言說這些高脂肪快餐只能提供給我們一樣東西——通向死亡的捷徑。

　　另一方面，有些人認為基本的快餐食品中含有我們需要的所有營養。畢竟，這些食品中有肉、牛奶、色拉(如果你額外買了的話)和面包。[3]如果你用夾干酪的漢堡包代替普通漢堡包，你就額外多吸收了一些于已有益的蛋白質。這些褒獎之辭所忽略的是那些小面包通常太過柔軟;麥芽糖和可樂里的糖份過多;以及漢堡包，為了使其變得可口，里面加入了過量的鹽。

　　你于是決定遠離漢堡包連鎖店，只從超市里買食物。這樣你就更加安全了嗎?答案是除非你要的不是冷凍或罐頭食品。專家告訴我們罐裝和冷凍蔬菜含有糖和其他各種對人的身體健康無益的東西。[4]根據這些人的觀點，保證食品對健康有益的唯一戰術就是自己現買現做。接下來，當然嘍，你要吃掉它——這會產生另外一個問題。[5]當今社會的速度促使大家吃得太快了。我們沒有把食物嚼爛，匆匆忙忙地吃，或者剛剛吃完飯就一躍而起，去趕時間。
