Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things. In the hierarchy of foods, snacks are deemed trivial – perhaps even childish – especially in contrast to meals, which are seen as substantial and necessary. The multiple aisles devoted to sweet and savory treats in supermarkets, and the availability of snacks even at places like home improvement and department stores, speak to the popularity of snacking. But the ubiquity of snacks is relatively new and not common to all countries. Eurie Dahn traces the story of snacking culture through specific snacks, including Flamin’ Hot Cheetos, cheese crackers, and Choco Pies, and in the contexts of ethnicity, popular culture, diet culture, and even parenting. Snack is an idiosyncratic cultural history that offers surprisingly filling food for thought.
