Article: The food we eat seems to have profound effects 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 80 percent of all human illness are connected with diet and 40 percent of cancer is connected with the diet. Therefore, that food is connected with illness is not a new discovery. In 1940's scientists realized that nitrates , which are often used to keep color1 of meat, and other additives caused cancer. However these additives remain in our food and it becomes more difficult to know which additives are helpful or harmful. Farmers sometimes give drugs to animals not because the animals are ill but because they want to sell the animals at higher prices. For example, farmers try hard to make animals grow big so that they can sell the big animals for more money. Although the Food and Drug Administration has tried again and again to control farmers to do so, farmers go on doing this. Question: According to the passage, what has science done to mankind? Yes or no, is the answer "As a result of scientific invention, some things that may be harmful have been added to our food."?
Yes
