科学家已经了解了有关人类必需的食物的种类。据说，有7种食物是人类每日必需摄入的。它们是：（1）绿色及黄色的蔬菜类的食物，比如说青豆、胡萝卜、荷兰豆；（2）柑橘水果和西红柿；（3）土豆及其它水果和蔬菜；（4）肉类的食物，鱼以及蛋类；（5）牛奶及各种奶制品如奶酪和冰激淋；（6）面粉和谷物，米饭也包括在内；（7）黄油和像黄油那样的油脂类食物。
不同国家、不同地域的人们吃不同的食物，并且有着不同的饮食方式。然而最重要的是，我们说，一个人每天都要进食以上所说的7种类型中每个类型里的食物。
要养活世界上持续增长的人口，我们面临两个问题，一是如何控制人口使每个人都得到温饱；二是保证世界各地的人们都能够得到适当的饮食分配，使他们看起来既健康又强壮。
