During the Second World War, as Canada struggled to provide its allies with food, public health officials warned that malnutrition could derail the war effort. Posters admonished Canadians to "Eat Right" because "Canada Needs You Strong" while cookbooks helped housewives become "housoldiers" through food rationing, menu substitutions, and household production. Ian Mosby explores the symbolic and material transformations that food and eating underwent as the Canadian state took unprecedented steps into the kitchens of the nation, changing the way women cooked, what their families ate, and how people thought about food. Canadians, in turn, rallied around food and nutrition to articulate new visions of citizenship for a new peacetime social order.
