Parents of young children, and even some pet owners, will pay high prices for organic food if they think it's healthier. But many others think organic food is just a waste of money.

B. There is one main difference between organic and non-organic food. Organic farms do not use agricultural chemicals such as pesticides that stop insects from damaging crops. In many countries foods that claim to be organic must have special labels that guarantee that they are organic.

C. Is organic food safer and more nutritious? This is an important part of the debate. Many farmers and consumers believe it is. They think agricultural chemicals can cause serious illnesses like cancer, but there isn't much evidence proving this is true. However, recent studies have shown that eating organically-grown produce reduces your chances of developing heart disease.

D. Many doctors think it's more important to stop dangerous bacteria from contaminating foods. These bacteria can contaminate both organic and non-organic fruit and vegetables, and doctors recommend washing carefully before eating it. Meat, fish and chicken can also become contaminated, so washing them is also very important. Many doctors also believe we should reduce the amount of sugar in our diets, and there is a lot of evidence to support this idea.
