Historians of colonial and postcolonial attempts to deal with undernutrition in Africa have generally argued that, after the Second World War, scientists and doctors “medicalized” hunger by emphasizing specific deficiencies that could be medically “cured” or alleviated through dietary supplements, thereby covering up the economic, social, and political causes of (post)colonial hunger. This article argues that this explanation obscures the persistence of a more holistic approach immediately after the Second World War, which rejected this narrow vision of hunger and, on the contrary, framed it as a very broad problem requiring interdisciplinary research and ambitious economic and social solutions. It focuses in particular on the work of British nutrition specialist B. S. Platt and his “experiment” in The Gambia that was meant to devise a replicable recipe to cure colonial malnutrition through mechanization and agricultural development. Like many other such colonial projects, the project ended in dismal failure, but it illustrates how malnutrition was understood at the end of the war as a broad economic and social problem. It also shows how this more holistic approach was tightly associated with the postwar project of colonial “development” and was predicated on an ambition to thoroughly re-engineer colonial landscapes and subjects.
