During WWII, as Canada struggled to provide its allies with food, nutritionists warned that malnutrition could derail the war effort. Posters admonished women and children to “Eat Right, Feel Right” because “Canada Needs You Strong” while cookbooks helped housewives become “housoldiers” through food rationing, menu substitutions, and household production. Food Will Win the War explores the symbolic and material transformations that food and eating underwent during the war and the profound social, political, and cultural changes that took place in the 1940s. Through official food guides and policies, the state took unprecedented steps into the kitchens of the nation, transforming 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 their postwar future.
