From the news I read about Four scientists have won the 2016 World Food Prize. Scientists are from the International Potato Center. They won prizes for making sweet potatoes healthier. This is beneficial to millions of people around the world. Scientists develop sweet potatoes that have an extra amount of vitamin A. This means it contains more nutrients. One researcher said it was difficult to get a farmer to help him work. Researchers say: "They say that it is a bad idea." Farmers say their job is to plant more potatoes, kill pests and reduce poverty, not improve nutrition. Scientists also say it is a big reason children become blind. Jan Low, of the International Potato Center, says that gift-winning sweet potatoes can make a big difference. People who are hungry can get enough vitamin A. He hopes more scientists will grow vegetables that have extra nutrients.
