Commercial determinants of mental health.

An editorial is presented on the impact of multinational companies (MNCs) on mental health, namely how they change policies, surroundings, and social variables that affect people's well-being. It focuses on how MNC advertising and marketing methods, notably in areas such as food, drink, and gambling, lead to physical and mental health difficulties, with a specific emphasis on the rise of obesity in the U.K. as a result of the fast-food business.
