  Passage 2

  The food we eat seems to have profound effects on our health.  Although science has made enormous steps inmaking 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.Difficult cultures are some 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 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 poultry and because of this,penicillin has been  found in the milk of treated cows.Sometimes similar drugs are  administered(given) 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 has tried repeatedly to control these procedures,the  practices continue.
