The food we eat seems to have a great effect on ourhealth. Although science has made big steps in making food more fit to eat, ithas, at the same time, made many foods unfit to eat. Some research has shownthat perhaps eighty percent of human illness is related to food and fortypercent of cancer is related to food as well. That food is related to illnessis not a new discovery. In 1945, some researchers realized that things commonlyused to keep colour in meats and other food additives（添加剂）caused cancer.

Yet, these additives remain in our food, and it isdifficult to know which things on the wrappings（包装）offoods 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, penicillinhas been found in the milk of cows. Sometimes similar tings are supplied toanimals not for their health, but just to make a profit.

The farmers are simply trying to fatten the animals inorder to get a higher price on the market. Although some countries have triedto control such things, the practice continues.
