Food in detention is not a privilege; it is a fundamental human right and a core obligation under international humanitarian and human rights law. Across custodial systems globally, food insecurity and diet-related obesity coexist, undermining health, dignity, and rehabilitation while reflecting broader structural inequities. Grounded in ICRC guidance on economic security in detention and United Nations standards including the Mandela Rules, this ICPA webinar examines how correctional systems can move toward nutrition that protects health and human dignity.
