Diet and Nutrition: Research in Progress

RAND Health researchers are currently working on the following projects related to obesity, diet, and nutrition.

Supermarket Experiment to Improve Dietary Behaviors

A natural experiment, called PHRESH (Pittsburgh Hill/Homewood Research on Eating, Shopping & Health), that examines the extent to which the opening of a full-service grocery store in a low-income, predominantly African-American neighborhood in Pittsburgh, PA, influences changes in residents' diet and food purchasing over a three-year period.

Evaluation of the Healthy Food Program

An analysis of changes in purchasing behavior, self-reported diets, and other health outcomes among participants in the Healthy Food benefit program, started by the South African health insurance company Discovery, to understand the effect of meaningful price discounts for healthier foods at the population level.
