If humans are what they eat, it is not so much or only because the substances they gradually incorporate constitute their physical materiality, but also because, from a cultural point of view, the food they prepare and ingest represents them, signifies them, and contributes to their individual and collective identity. Enhancing this signifying function of food, photography is a perfect tool for analyzing and understanding entire civilizations, men and women, society, the environment, and many other subject. This book, which accompanies the fifth edition of the Biennale Foto/Industria, organized by the Fondazione MAST and entirely dedicated to the theme of the food industry, is intended to trigger a series of reflections on the complexity of the food issue.
