      The food we eat seems to have a great effect on our health. Although science has made big steps in

making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has

shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is

related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers

realized that things commonly used to keep colour in meats and other food additives (添加剂) caused

cancer.

     Yet, these additives remain in our food, and it is difficult to know which things on the wrappings (包

装) of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give

penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes

similar tings are supplied to animals not for their health, but just to make a profit.

     The farmers are simply trying to fatten the animals in order to get a higher price on the market.

Although some countries have tried to control such things, the practice continues.
