This book explores the role of digital media technologies in creating new forms of consumer activism and engagement with food, eating and food systems. Food is an increasingly prominent subject of engagement online, from the aesthetics of cooking to the ethics of shopping. This book adopts a multi-disciplinary approach, bringing together food studies, and science and technology studies. The role of social media, apps, and other online technologies is considered in relation to activist and consumer issues in the UK, Australia, Europe and South America. Digital Food Activism explores a variety of contemporary topics, including Twitter and diabetes, hashtag activism and the prospect of 3D printed food.
