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 the diet as well. 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 illnesses is not a new discovery. In 1945, government researchers realized that carcinogenic nitrates (致癌硝酸盐), commonly used to preserve color in meats, and other food additives (添加剂), caused cancer. However, 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. Farmers often give penicillin to cows and other 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 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 has tried repeatedly to control these procedures, the practices continue.

The results found after taking account of some influential factors, a leading processed food diet at the age of three was associated with a lower IQ at the age of eight and a half, whether the diet was improved after that age.

Every 1 point increase in dietary pattern score was associated with a 1.67 fall in IQ.
