Small, sick, listless children have long been India’s scourge — “a national shame,” in the words of its prime minister, Manmohan Singh. But even after a decade of galloping economic growth, child malnutrition rates are worse here than in many sub-Saharan African countries, and they stand out as a paradox in a proud democracy. [...] A World Food Program report last month noted that India remained home to more than a fourth of the world’s hungry, 230 million people in all. It also found anemia to be on the rise among rural women of childbearing age in eight states across India. Indian women are often the last to eat in their homes and often unlikely to eat well or rest during pregnancy.
