问题     In most corners of the world malnutrition is plainly a matter of outright insufficiency of food for the population--where the majority of the people do not obtain enough food calories to meet minimal needs for support of physical work and for maintenance of health. Elsewhere the problem may be not one of insufficient, calories but of lack of specific nutrients essential for health.
    In Latin America, as in other places, the dread protein deficiency disease kwashiorkor is taking its heavy toll of children’s lives. Strategic vitamins and minerals may be lacking due to traditional diets which are nutritionally imbalanced. Here people continue their eating pattern year after year without knowledge of that their dietary habits are doing to themselves and to future generations.
    With a basic knowledge of nutritional needs and deficiencies, efforts could be directed to finding food substitutes which could meet these needs. Mixtures of vegetable proteins, like soybeans and peanuts, could provide an abundance of cheap, useful protein where meat, eggs, and milk are not within economic reach of large groups in the population. Efforts could also be expended on increasing the agricultural productivity in specific regions; where large areas are given over to relatively inefficient use as grazing land, the intensive production of vegetable protein crops could bring remedial nutrition to an undernourished population.  Elsewhere, enrichment with specific vitamins and minerals of traditional staple foods that are deficient in essential nutritive factors could wipe out disabling deficiency diseases, like beriberi or pellagra, almost overnight. Similarly, addition of minute amounts of inexpensive iodine to salt could benefit large areas where endemic goiter has been accepted as an integral part of life for generations.
Kwashiorkor ______.
选项 A、is especially harmful to children
B、resembles beriberi
C、is caused by starvation
D、affects adults only
答案A
解析 恶性营养不良对儿童尤其有害。根据第二段第一句，正如在其他地区那样，目前，拉丁美洲可怕的蛋白质缺乏症夸希奥科病夺去大量儿童的生命。
