Development blogger Tom Murphy reports in Humanosphere about a recent report looking at malnutrition and micronutrient deficiencies. “Researchers collected data on micronutrient deficiencies in young children to map areas where the problem is concentrated,” and they developed the Hidden Hunger Index, published recently in PLOS One, he notes. Klaus Kraemer, director of Sight and Life and co-author of the paper, said the private sector and civil society have roles to play in helping improve micronutrient uptake, and he “hopes that the index can help bring hidden hunger to the greater malnutrition discussion,” according to Murphy (6/26).
