Lecture 3 - Biology, Nutrition and Health I: What We Eat

This video was recorded at YALE PSYC 123 The Psychology, Biology and Politics of Food with Professor Kelly D. Brownell. This lecture focuses on how people measure nutrition and what it means for health. Professor Brownell reviews methods to track food intake, from a population level to an individual level, emphasizing methods and measurement error as well as portion underestimation. The definition of a calorie and how it is measured are also discussed, as well as people's changing relationships with macronutrients and micronutrients in food and with water.
