Global obesity rates remain high in high-income countries and are rapidly increasing in low- and middle- income countries, while concurrently consumption of unhealthy products continues to rise. The ongoing expansion of multinational food and beverage companies, or 'Big Food', is a key factor behind these trends. This collection provides critical insight into the global expansion of 'Big Food', including its incursion into lower income countries. It examines 'Big Food' marketing strategies, including the way in which they advertise to youths and the rural poor. This book was originally published as a special issue of Critical Public Health.
