Experiments under way in several labs aim to create beneficial types of genetically modified foods, including starchier potatoes and caffeine-free coffee beans. Genetic engineers are even trying to transfer genes from a cold-winter fish to make a frost-resistant tomato. A low-sugar GM strawberry now in the works might one day allow people with health problems such as diabetes   to enjoy the little delicious red fruits again. GM beans and grains rich in protein  might help people at risk of developing kwashiorkor. Kwashiorkor, a disease caused by severe lack of protein, is common in parts of the world where there are severe food shortages. Commenting on GM foods, Jonathon Jones, a British researcher, said: "The future benefits will be enormous , and the best is yet to come". To some people, GM foods are no different from unmodified foods. "A tomato is a tomato," said Brian Sansoni, an American food manufacturer. Critics of GM foods challenge Sansoni's opinion. They worry about the harm that GM crops might do to people, other animals, and plants. In a recent lab study conducted at Cornell University, scientists tested pollen  made by BT corn, which makes up one-fourth of the U.S. corn crop. The scientist dropped the pollen onto milkweed, a plant that is the only known food source of a butterfly caterpillar . Within four days of feeding on the leaves, almost half of a test group of caterpillars died. "This is a warning bell." said Cornell researcher Linda Raynor. Some insects that are not killed by GM foods might find themselves made stronger. How so? The insecticides are used on the crops to kill the pests. But GM plants produce a continuous level of insecticide. Insects relying on those crops may develop resistance to the plants and they may also develop a resistance to the insecticide. At the forum on GM food held last year in Canada. GM crops that have been made resistant to the herbicide might crossbreed with wild plants, creating "superweeds" that could take over whole fields. So where do you stand? Should GM food be banned in the United States, as they are in parts of Europe? Or do their benefits outweigh  any of the risks they might carry? Which of the following statements concerning banning GM foods is true according to the passage?
Underdeveloped countries have banned GM foods. Both Europe and the U.S. have banned GM foods. Most European countries have not banned GM foods. The United States has not banned GM foods.
