Although encouraging people to eat more nutritiously can promote better health, most efforts by companies, health professionals, and even parents are disappointingly ineffective. Brian Wansink’s Marketing Nutrition focuses on why people eat the foods they do, and what can be done to improve their nutrition. Wansink argues that the true challenge in marketing nutrition lies in leveraging new tools of consumer psychology (which he specifically demonstrates) and by applying lessons from other products’ failures and successes. The key problem with marketing nutrition remains, after all, marketing.
