问题     Systematic efforts at national nutrition planning in developing
countries go back barely a decade. During that brief time there has
been considerate progress in establishing the extent and causes of【M1】______
malnutrition and what can be done to reduce it.
    Ten years ago, malnutrition was often thought of to reflect【M2】______
primarily a shortage of protein(and in some cases, vitamins or
minerals). Most nutrition programs concentrated on providing
high-protein food to children, usually in schools. However, emphasis【M3】______
today is similar. There is now a wide measure of agreement on several
broad propositions. Serious and extensive nutritional deficiencies
occur in virtually all developed countries, though they are worst in【M4】______
low-income countries. They are usually caused by undernourishment,
not by an imbalance of calories and protein. There may often be【M5】______
shortage of specific micronutrients and of protein, especially with【M6】______
young children.
    But giving the typical composition of the diets of the poor, to【M7】______
the extent that calorie requirements(as estimated by the FAO and the
WHO)are met, it is unlikely that other nutritional needs will also be【M8】______
satisfied. Malnutrition affects old and young, male and female, urban
and rural dwellers; particularly prevalent among children under five,
it reduces their resistance of diseases and is a major cause of their【M9】______
death. In many societies, girls suffer more than boys. Malnutrition
is largely a reflection of poverty; people do not have enough ample【M10】______
income for food. On the condition of the slow income growth that
is likely for poverty-struck people in the foreseeable future, a large
number of people will remain malnourished for decades to come.
