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 , atthe
same time, made many foods unfit to eat. Some research has shown that perhaps
eighty percent of cancer is related to the diet as well, especially cancer the
colon . Different cultures are more prone to contract certain illnesses because
of the food that is characteristic in these cultures. That food related to
llness is not a new discovery. In 1945 , government researchers realized that
itrates and nitrites, commonly used to preserve color in meats, and other food
dditives, caused cancer. Yet, these carcinogenic additives remain in our food,
nd it becomes more difficult all the time to know which things on the pack ging
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 poultry, and
because of this, penicillin has been found in the milk of treated cows.
Sometimes similar drugs are administered to animals not for medicinal 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 controlthese procedures, the
practices continue.
