Accounting for the Social Gradient in Diet Quality & Health

The purpose of this research is to assess the relationship between the cost and quality of diets consumed by groups differing in socioeconomic and demographic characteristics. The study is made possible by merging new national data on food prices with the National Health and Nutrition Examination Survey (NHANES), a population-based survey of diet and health.

This work addresses economic barriers to nutritious diets and thus provides a vital part of the research on socio-economic disparities in health. The long term goal of this research is to establish a new approach to estimating diet cost that links directly to estimates of nutrient intake. The approach will allow investigators to assess food cost as a factor influencing the dietary behaviors of individuals and large populations.
