In October 1949 the United Nations brought a number of specialists on food on Geneva, to discuss the problems of eating habits and food supplies of people throughout the world. One problem that interested the specialists particularly was a form of illness, about which little was known among the children in Africa.

    Two doctors were chosen to make the study. They flew to Africa and during the next two months visited ten countries. They found that serious diseases of poor eating, often mistaken for other diseases, existed in all parts of Africa. The diseases were similar and could therefore all be named kwashiorkor(恶性营养不良).

    The diseased children are usually from one to four years old. As the illness progresses, the child’s stomach becomes swollen(肿胀的) by liquid collecting in the body. The skin changes colour and may break out in open sores(伤口). The hair changes colour and starts to fall out. The patient loses all interest in his surroundings and even in food, and becomes so weak that he wants to lie down all the time. Stomach liquids are no longer produced.

    The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat. Their mothers, after stopping their breast-feeding, gave them foods full of starches(淀粉) instead of greatly needed proteins(蛋白质). They found that the addition of milk to the food of children suffering from kwashiorkor saved many lives.

    It was necessary that the children of Africa be helped to eat better. The doctors suggested that the production of foods rich in protein be increased; they thought that more fish should be caught and more nuts should be grown. That urged education plans to teach mothers better ways of feeding children. They suggested that the United Nations should send large quantities of powdered milk to hospitals and child-health centres. Finally, they suggested closer study of all the special problems connected with kwashiorkor.

A child's birthday party doesn't have to be a hassle; it can be a basket of fun, according to Beth Anaclerio, an Evaston mother of two, ages 4 and 18 months.

　　"Having a party at home usually requires a lot of running around on the part of the parents, and often the birthday boy or girl gets lost in wild excitement. But it really doesn't have to be that way," said Anaclerio. Last summer, Anaclerio and her friend Jill Garlisle, a Northbrook mother of a 2-year-old, founded a home party-planning business called "A Party in a Basket." Their goal is to help parents and children share in the fun part of party planning, like choosing the subject or making a cake, while they take care of everything.

　　Drawing on their experiences as mothers, they have created（制作）10 ready-to-use, home party packages. Everything a family needs to plan a party, except the cake and ice cream, is delivered to the home in a large basket.

　　"Our parties are aimed for children 2 to 10."Anaclerio said, "and they're very interactive（互动）and creative in that they build a sense of drama based on a subject. For example, at the Soda Shoppe party the guests become waiters and waitresses and build wonderful ice cream creations."

　　The standard ＄200 package for eight children includes a basket filled with invitations, gifts, games and prizes, paper goods, a party planner and the like. For more information, call Anaclerio at 708-864-6584 or Carlisle at 708-205-9141.
