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, at the same time, made many foods unfit to eat. Some research has shown that perhaps 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 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 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. What is the main topic of the passage（）

Brazil has become one of the developing world’’s great successes at reducing population growth—but more by accident than design. While countries such as India have made joint efforts to reduce birth rates, Brazil has had better result without really trying, says George Martine at Harvard. Brazil’’s population growth rate has dropped from 2.99% a year between 1951 and 1960 to 1.93% a year between 1981 and 1990, and Brazilian women now have only 2.7 children on average. Martine says this figure may have fallen still further since 1990, an achievement that makes it the envy of many other Third World countries. Martine puts it down to, among other things, soap operas (通俗电视连续剧，肥皂剧) and installment (分期付款) plans introduced in the 1970s. Both played an important, although indirect, role in lowering the birth rate. Brazil is one of the world’’s biggest producers of soap operas. Globo, Brazil’’s most popular television network, shows three hours of soaps six nights a week, while three others show at least one hour a night. Most soaps are based on wealthy characters living the high life in big cities. "Although they have never really tried to work in a message towards the problems of reproduction, they describe middle and upper class values not many children, different attitudes towards sex, women working," says Martine. "They sent this image to all parts of Brazil and made people conscious of other patterns of behavior and other values, which were put into a very attractive package." Meanwhile, the installment plans tried to encourage the poor to become consumers. "This led to an enormous change in consumption patterns and consumption was in compatible (不相容的) with unlimited reproduction," says Martine. According to the passage, Brazil has cut back its population growth ______.
