The food we eat seems to have a profound impact 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 diet and forty percent of
cancer is related to the diet as well, especially cancer of the colon. Different
cultures are more prone to contract certain 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 nitrates and
nitrites, 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 in 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 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 control these procedures, the practices continue.
