Josette sheeran , the head of the united nations world food program says that many of the world 's poorest people cannot buy food because of soaring prices .
联合国世界粮食计划署负责人约瑟特.施林说，很多世界上最贫困的人都由于飞涨的物价而买不起粮食。
Ms sheeran said that in response to rising food costs , families in developing countries were moving in some cases from three meals a day to just one , or dropping a diverse diet to rely on one staple food .
" And so what we 're finding is that often energy bidders can outbid food buyers and consumers , and the higher the price of oil is the higher the price the energy producers are willing to pay , " said josette sheeran .
The world food programme , whose head josette sheeran took part in a meeting of experts brown called yesterday to discuss the crisis , said a " silent tsunami " threatened to plunge over 100 million people on every continent into hunger .
