Authors: Kara A. Christensen, PhD, Vivienne M. Hazzard, PhD, MPH, RD, Brianne N. Richson, MA, and Kelsey E. Hagan, PhD
Lead author Lindsey Parnarouskis, MS, reviews a secondary analysis of data collected in two earlier studies: Maternal Adiposity, Metabolism and Stress (MAMAS) the Family Food Study (FFS). This new study found that women experiencing food insecurity and greater access to highly processed foods more frequently report symptoms of food addiction, such as compulsive eating of certain types of food, unsuccessful attempts to cut down and withdrawal symptoms.

Diet Quality in the United States Improved during the Great Recession and Deteriorated During Economic Recovery
Authors: Annie Yu-An Chen, DDS, MS, and Roland Sturm, PhD
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 2011 and 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.

Lead author Michelle Barrack and principal investigator Adam S. 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.

Barriers to Accessing Healthy Food and Food Assistance During the COVID-19 Pandemic and Racial Justice Uprisings: A Mixed-Methods Investigation of Emerging Adults' Experiences
Authors: Nicole Larson, PhD, MPH, RDN, Tricia Alexander, Jaime C. Slaughter-Acey, PhD, MPH, Jerica Berge, PhD, MPH, Rachel Widome, PhD, MHS, and Dianne Neumark-Sztainer, PhD, MPH, RD
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.

Evidence That Changes in Community Food Environments Lead to Changes in Children’s Weight: Results from a Longitudinal Prospective Cohort Study
Authors: by Punam Ohri-Vachaspati, PhD, RD; Francesco Acciai, PhD; Kristen Lloyd, MPH; David Tulloch, PhD; Robin S. DeWeese, PhD, RDN; Derek DeLia, PhD; Michael Todd, PhD; and Michael J. Yedidia, PhD
An innovative new study in the Journal of the Academy of Nutrition and Dietetics provides data on how changes in the food environment around low-income and high-ethnic/racial minority populations impact childhood obesity over time. It shows that increased availability of small grocery stores selling a selection of healthy items in close proximity to children’s homes improves their weight status, whereas increased availability of convenience stores selling predominantly unhealthy foods is likely to be detrimental.

Location, Location, Location: Eye-Tracking Evidence that Consumers Preferentially View Prominently Positioned Nutrition Information
Authors: Dan J. Graham, PhD and Robert W. Jeffery, PhD
Video: Watch firsthand as investigators from the University of Minnesota used a computer equipped with an eye-tracking device to determine that most consumers pay less attention to Nutrition Facts labels than they report. Further data suggest that average consumers view label components at the top more than those at the bottom and read only the top five lines on a Nutrition Facts label. Prominently positioning key nutrients, and labels themselves, could substantially impact public health. Video provides supplemental content to the article published in the Journal.
