Walmart and Other Food Retail Chains: Trends and Disparities in the Nutritional Profile of Packaged Food Purchases.

ABSTRACT:

Introduction

Proliferation of food retail chains has created an environment in which a few food retailers account for the majority of U.S. packaged food purchases (PFPs). Despite the major potential for these food retail chains (FRCs) to impact what U.S. consumers buy and eat, little is known about the nutritional profile of PFPs from these retailers, particularly PFPs from Walmart, the largest U.S. grocer.

Methods

A data set of household PFPs from Nielsen Homescan was linked to data from the Nutrition Facts Panel (N=164,315), analyzed in 2014. Fixed effects models and inverse probability weights accounting for selectivity of shopping at a retailer were used to examine shifts in nutrient densities and key food groups purchased at Walmart and other FRCs from 2000 to 2013, and
