Lead author Yangbo Sun, MBBS, PhD, The University of Tennessee Health Science Center, shares the results of a large prospective study of American adults 40 years old and older (NHANES). This research contributes much-needed evidence about the association between eating behaviors and mortality in the context of meal timing and duration of the daily prandial period.

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.

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)

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.

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.

Authors: by Kelsey A. Vercammen, MSc, Alyssa J. Moran, ScD, RD, Mark J. Soto, MA, Lee Kennedy-Shaffer, PhD, and Sara N. Bleich, PhD Podcast: Lead author Kelsey A. Vercammen (Harvard T.H. Chan School of Public Health) talks about a new Journal of the Academy of Nutrition and Dietetics study that shows the percentage of heavy sugar-sweetened beverage drinkers trended downwards in most demographic categories, but attention should be paid to several subgroups with high intake for whom trends are not decreasing.

Authors: Elizabeth K. Dunford, PhD; Donna R. Miles, PhD; Shu Wen Ng, PhD, and Barry Popkin, PhD Podcast: Reducing sugar consumption is an important public health strategy. Shu Wen Ng, PhD, discusses a new study from The University of North Carolina at Chapel Hill that shows US household purchases of foods and beverages containing caloric sweeteners declined between 2002 and 2018 but increased for products with both caloric sweeteners and artificial sweeteners.

Authors:Authors: Kirsten A. Herrick, PhD, MSc, Cheryl D. Fryar, MSPH, Heather C. Hamner, PhD, MS, MPH, Sohyun Park, PhD, and Cynthia L. Ogden, PhD, MRP Podcast: Lead investigator Kirsten A. Herrick, PhD, MSc, highlights findings from the first study to look at trends in added sugars consumption by toddlers and infants. Nearly two-thirds of infants (61 percent) and almost all toddlers (98 percent) consumed added sugars in their average daily diets, primarily in the form of flavored yogurts (infants) and fruit drinks (toddlers).

Authors: Aaron C. Miller, PhD; Linnea A. Polgreen, PhD; Elena M. Segre, MD; and Philip M. Polgreen, MD, MPH Podcast: Linnea A. Polgreen, PhD, and Aaron C. Miller, PhD, discuss a new study from the University of Iowa that shows levels of satisfaction derived from food differ among adults who were normal-weight, overweight, and obese and that individuals with obesity get more satisfaction from their food. This quantification of satisfaction from food may help explain why some people eat more than others. July 30, 2019 (https://doi.org/10.1016/j.jand.2019.05.018)

Authors: Megan A. McCrory, PhD; Allen G Harbaugh, PhD; Sarah Appeadu, MS; and Susan B Roberts, PhD Video: Dr. Megan McCrory and colleagues present new insights on how fast food may be helping to fuel the continuing problem of obesity and related chronic conditions in the US. They examined changes over a 30-year period of menu items offered by 10 of the top fast-food restaurants. February 27, 2019 (https://doi.org/10.1016/j.jand.2018.12.004)
