Four scientists have won the 2016 World Food Prize. The scientists are from the global agricultural research group the International Potato Center. They won the prize for enriching sweet potatoes. This has resulted in health benefits for millions of people across the world. The scientists developed a way to grow sweet potatoes that have extra amounts of Vitamin A in them. More Vitamin A means the sweet potato contains extra nutrition. One researcher said it was difficult to get farmers to help him with his work. Many farmers did not think it was a good idea. The researcher said: "They told me it was a bad idea. Their job was to increase yields, pest resistance and reduce poverty; it wasn't to improve nutrition."

四位科學(xué)家贏得2016年世界糧食獎。這些科學(xué)家來自全球農(nóng)業(yè)研究小組國際馬鈴薯中心。他們因為讓紅薯更加富有營養(yǎng)而贏得該獎項。他們的研究使全世界數(shù)百萬人的健康收益。這些科學(xué)家研究了一種可以增加紅薯維生素A含量種植方法。維生素A含量增加意味著紅薯更有營養(yǎng)。一位研究人員表示，讓農(nóng)民幫助他進行這項工作非常困難。許多農(nóng)民不認為這是一個好主意。這位研究院表示：“他們告訴我，這個主意很糟糕。他們的工作是增加產(chǎn)量，防御害蟲，減輕貧困，而不是增加營養(yǎng)。”

The sweet potato could change the lives of many people across the globe. People without food can die of malnutrition – not having enough to eat. A lack of Vitamin A is one of the most harmful examples of malnutrition. Scientists say malnutrition affects more than 140 million children up to the age of four in 118 countries. It also affects more than seven million pregnant women. Scientists also say it is a big reason for children becoming blind in developing countries. Jan Low, from the International Potato Center, said the prize-winning sweet potatoes could make a big difference in making sure hungry people get enough Vitamin A. She hopes more scientists will focus on increasing nutrition in vegetables.

紅薯可以改變?nèi)蛟S多人的生活。許多沒有食物的人會死于營養(yǎng)不良，因為沒有足夠的吃的。缺乏維生素A是營養(yǎng)不良中最有害的情況?？茖W(xué)家表示，營養(yǎng)不良影響著118個國家超過1.4億名4歲以下兒童。還影響著超過700萬孕婦?？茖W(xué)家還表示，缺乏維生素A也是發(fā)展中國家許多兒童眼盲的原因。來自國際馬鈴薯中心的Jan Low表示，贏得世界糧食獎的紅薯可以確保饑餓的人們獲得足夠的維生素A。她希望更多科學(xué)家能夠關(guān)注如何增加蔬菜中的營養(yǎng)。
