Answer 1

科学家们掌握了很多种人体需要的食物。他们说有一些种类的食物是人们每天都应该吃的。它们是：1. 各种绿色和黄色的蔬菜 2. 柑橘类的水果和西红柿 3. 土豆，还有其它的水果及蔬菜 4. 各种肉、鱼和蛋类 5. 牛奶和奶制品 6. 面包或早餐片，米饭也属于此类 7. 黄油或类似食物。

不同国家和地区的人食用不同种类的食品，食品的烹调和食用方式也各不相同。不同国家的人在不同时间吃饭。在一些地方的人每天只吃一顿到两顿饭；在另一些国家，人们每天吃三到四顿饭。科学家们说这些差异都没什么大不了的。食物是生着吃还是被弄熟了吃，是罐头装的还是冷藏的并不重要。一个人是在4点吃晚饭还是在晚上11点吃也不重要。

目前对于全球广大人众的饮食问题，尚有两大难题。第一是想方设法让全世界的人都不饿肚子。另一个则是确保各地的人们吃恰当的食物以使他们健康强壮地成长。
