Project: Mapping Lay Theories of Healthy Eating

As crucial as it is to life and health, food can be a source of great anxiety as people worry about what, how, and how much to eat. In his book, Michael Pollan writes that he beliefs Americans struggle with the “omnivore’s dilemma”: since humans can eat anything, we cannot decide what we should eat. How do individuals from different backgrounds and cultures decide what health eating is? As people form their theories of what it means to eat well, they create mental models of “healthy eating”and perceive causal links between what and how one eats and their well-being in different ways.

Our project focuses on these lay perceptions and asks: what does healthy eating mean to individuals, how people rationalize their beliefs, and why do they think differently?
