The food we eat seems to have a great effect on our health.Although science has made big 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 human illness is related to food and forty percent of cancer is related to food as well.That food is related to illness is not a new discovery.In 1945,some researchers realized that things commonly used to keep colours in meats and other food additives caused cancer.Yet,these additives remain in our food,and it is difficult to know which things on the wrappings of foods are helpful or harmful.The additives which we eat are not all so direct.Farmers often give penicillin to their animals,and because of this,penicillin has been found in the milk of cows.Sometimes similar things are supplied to animals not for their health,but just to make a profit.

The farmers are simply trying to fatten the animals in order to get a higher price on the market.Although some countries have tried to control such things,the practice continues.
