Cheap protein substitutes from milk, eggs and meat________. [br]
In most corners of the world malnutrition is plainly a matter of outright insufficiency of food for 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 on children’s lives. Strategic vitamins and minerals may be lacking due to traditional diets which are nutritionally unbalanced. Here people continue their eating pattern year after year without knowledge of what their dietary habits are doing to themselves and to future generation. With a basic knowledge of nutritional needs and deficiencies, efforts would 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 meats, eggs, and milk are not within economic reach of large groups in the population. Efforts could also be expanded 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.

1)注意开篇第一句,此句中的关键表达部分往往是全篇讨论的重点内容;2)注意篇章中某一类词或短语出现的频度,若频度高则表明这类词或短语表达的内容是全文讨论的重点。本题原文中关于营养不良的词汇和短语出现频度颇高,如有malnutrition,lack of specific nutrients,dread protein deficiency,nutritionally.imbalanced,nutritional needs,deficiencies及remedial nutrition等。
