Peanut butter. It’s a staple[主食] of childhood sandwiches and a nightmare for parents whose kids have nut

allergies[过敏症]. Now it might also be a cure for hunger in Sub-Saharan Africa注, or so say scientists at the Washington

University School of Medicine in St. Louis. These researchers

have used a nutrient-rich paste[糊] made from peanuts, powdered milk, oil and sugar spiked[掺入] with added

vitamins and minerals to combat[战斗] starvation in thousands

of children in Malawi. Nearly three quarters of the kids there are malnourished[营养不良的], and more than 10% die from it before the age of five. The scientists enlisted[征募]

village health aides to identify those who needed help. Of the two thousand severely malnourished children

who were given the peanut paste, 89% recovered. That’s far better than the 50% recovery rate seen in starving kids who are treated with a porridge[麦片粥]

made of corn or milk, probably because peanut butter

is packed with[以……充满] protein[蛋白质] and calories[卡路里].

A hungry child would have to eat 25 spoonfuls of porridge to equal the calories in just one glob[一团] of peanut paste. Best of all, the peanut butter is produced locally, does not require cooking, and could be administered by doctor “mom.”
