A

The food we eat seems to have far-reaching effects on our health. Although science has made great 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 all human illnesses are related to diet and forty percent of cancer is related to diet as well, especially cancer of the colon(结肠). Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that carcinogenic nitrates, commonly used to preserve color in meats, and other food additives(添加剂), caused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed(经过加工的) food are helpful or harmful. The additives, which we eat, are not all so direct. Farmers often give penicillin(青酶素) to beef and living animals, and because of this, penicillin has been found in the milk of treated cows. Sometimes, similar drugs are given to animals not for medical purposes, but for financial(财政的) reasons. The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although the Food and Drug Administration has tried repeatedly to control these behaviors, the practices continue.
