 Research Accomplishments
 
 Adolescent and Adult Perceptions of Their Diet Quality
 Diet quality is improving in some US populations and awareness of recommendations for healthful eating may be increasing. Yet whether adolescents and adults can accurately assess their diet quality is not clear. My colleagues and I analyzed data from nationally representative sample of adolescents (16-19 years) and adults (20+ years)  from the National Health and Nutrition Examination Survey 2015-2018.
 /ARSUserFiles/40006/CatLion.png
 We determined that only 12% of adolescents and 15% of adults can accurately assess the quality of their diet, most notably, those who perceive their diet as poor. Additionally, almost all adolescents and adults who inaccurately assessed their diet quality, overrated it, sometimes to a substantial degree. Although there was a positive relationship between diet quality and perception of one's diet, approximately 85% of adolescents and 70% of adults scored failing grades for diet quality measures. Thus, the tendency of adolescents and adults to overrate the healthfulness of their diet suggests work is needed to educate US adolescents and adults about components of healthful dietary intake.
 
 Food and Nutrition Security
 Food security has been defined as "access by all people at all times to enough food for an active, healthy life" [USDA ERS]. In contrast, nutrition security has been defined as "having consistent access, availability, and affordability of foods and beverages that promote well-being and prevent (and if needed, treat) disease" [Mozaffarian et al. 2021]. While these two concepts are related, similarities and differences between them are not well studied.

 Using data obtained from the Gretchen Swanson Center for Nutrition, my colleagues and I conducted an analysis to quantify and compare causal pathways from food and nutrition security to (1) dietary choice and (2) healthfulness of food choice while also testing for mediation by utilization barriers to healthful meals and limited availability of foods. We discovered that food and nutrition security impact food choices with utilization barriers acting as an intermediary step. Additionally, when environmental and household barriers to food purchasing and preparation are high, the ability to decide what to eat does not differ between households with nutrition security and those without nutrition security.
