Food and Health 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 are related to the diet as well, especially cancer of the colon (结肠). Different cultures are more likely to develop certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery.

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 food are helpful or harmful. The additives which we eat are not all so direct.

Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue. Nitrates are usually used for keeping the smell of food.
