This book critically examines contemporary health and wellness culture through the lens of personalization, genetification and functional foods. These developments have had a significant impact on the intersecting categories of gender, race, and class in light of the increasing adoption of digital health and surveillance technologies like MyFitnessPal, Lifesum, HealthyifyMe, and Fooducate. These three vectors of identity, when analysed in relation to food, diet, health, and technology, reveal significant new ways in which inequality, hierarchy, and injustice become manifest. In the book, Tina Sikka argues that the corporate-led trends associated with health apps, genetic testing, superfoods, and functional foods have produced a kind of dietary-genomic-functional food industrial complex. She makes the positive case for a prosocial, food secure, and biodiverse health and food culture that is rooted in community action, supported by strong public provisioning of health care, and grounded in principles of food justice and sovereignty.
