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.
Helping Loncheras Offer Healthier Meals
A pilot study to see whether loncheras (Hispanic mobile food trucks) are willing to offer healthier meal options and if so, whether this is economically sustainable and profitable.
Evaluating the Los Angeles “Fast Food Ban”
Analysis of geocoded data from the California Health Interview Survey merged with data on food outlets to assess the effect of the 2008 zoning regulation that restricted opening or remodeling a fast food restaurant in South Los Angeles.
