Diet Quality in the United States Improved during the Great Recession and Deteriorated During Economic Recovery Apr 13, 2022

Show notes

Annie Yu-An Chen, DDS, MS, Assistant Policy Researcher at RAND Corporation, discusses a new study that examined cyclical changes in American diet quality related to macroeconomic conditions. She and co-author Roland Sturm, PhD, Senior Economist at RAND Corporation, found that the American diet improved when unemployment peaked after the Great Recession, and then declined significantly. This was particularly true in 2011and 2012, a period with historically high unemployment rates in the United States. However, since recovery began in 2013, the quality of the American diet has declined and is now at a 20-year low. (https://doi.org/10.1016/j.jand.2021.09.019)

Tenforde discuss the first investigation into the prevalence of dietary supplement and sport food use in male and female middle school-aged runners. Researchers found that almost half the study participants used these products on two or more days a week during the prior year. Characteristics associated with supplement use included a prior bone stress injury, following a vegetarian diet and behaviors suggesting dietary restrictions such as losing weight and skipping meals.

Discrimination and safety concerns are barriers to accessing healthy food for food-insecure young adults Jul 19, 2021

Show notes

Study lead Nicole Larson, PhD, MPH, RDN, talks about a University of Minnesota School of Public Health study that found one-third of emerging adults (18-29 years of age) surveyed experienced food insecurity during the COVID-19 pandemic and a disproportionately high prevalence of food insecurity and food insufficiency among those living with children and who identified as Black, Indigenous, or a person of color. The findings show an urgent need for research to address how the processes of racism that are embedded in the policies and practices of society and institutions are directly contributing to food insecurity.
