The food we eat seems to have profound effects on our health. Although science has made enormous 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 relate to diet and forty percent of cancer relates to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures.

That food is connected with illness is not a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic  additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.

The food we eat seems to have profound effects 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 80 percent of all human illness are connected with diet and 40 percent of cancer is connected with the diet as well that food is connected with illness is not a new discovery. In 1940’s scientists realized that nitrates（硝酸盐）, which are often used to keep color of meat, and other additives（添加剂）caused cancer. However these additives remain in our food and it becomes more difficult to know which additives are helpful or harmful. Farmers sometimes give drugs to animals not because the animals are ill but because they want to sell the animals at higher prices. For example farmers try hard to make animals grow big so that they can sell the big animals for more money. Although the Food and Drug Administration has tried again and again to control farmers to do so, farmers go on doing this.
