<p>Understanding the effect of food insecurity of vulnerable individuals is necessary to develop strategies for improving lives of those individuals. In this study I explore the effect of a low-cost, unobtrusive intervention on food pantry clients’ choice of healthier food items at a local food pantry. A cross-sectional study was conducted at a food pantry in the Midwest U.S. using the randomized controlled trial method. Participants in the intervention group received a nutrition ranking information about the food items in the pantry during their visit. Both the intervention and control groups reported their food selections. Additionally, client demographic information was collected in surveys. Data were collected from October 2018 to January 2019. A total of 615 adults were recruited and randomized for the nutrition ranking intervention (n=300) and control group (n=315).<b> </b>Multiple linear regression models were used to predict the outcomes of the intervention while controlling for demographic characteristics such as age, gender, household size, and education level. There was no significant response to the nutritional ranking intervention as it appears that the intervention was ineffective at changing behavior. Results suggest that future studies are needed to determine a low-cost intervention for food pantry clients during their short time at the food pantry.</p>

In the United States (U.S.), up to 40% of the entire food supply is lost or wasted, which contributes to negative environmental, economic, and social outcomes, with the majority of food waste occurring in the retail and consumer sectors of the food supply chain. Concurrently, 10.5% of U.S. households experienced food insecurity in 2019. Food insecurity rates are higher among individuals with low income and disproportionately affects ethically and racially diverse people living in poverty. Diverting excess food from retail and institutional settings to people in need is one method to reduce food waste and enhance individual, household, and community food security. This PhD dissertation describes four studies that explored food waste management in the U.S. among households with low-income and within U.S. food pantries, which are a critical component of the emergency food system. Study 1 consisted of a systematic review that examined differences in food waste attitudes and practices among consumers of across income levels. Study 2 was a quantitative research methods approach to examine food waste attitudes and practices of SNAP-eligible households (n=17). Study 3 was a cross-sectional quantitative approach to examine the impact of the novel coronavirus disease (COVID-19) pandemic on food waste management within U.S. food pantries (n=290). Study 4 assessed the feasibility of food pantries in Virginia (n=68) to implement marketing-mix and choice-architecture (MMCA) strategies within their food pantries given the changes they had to make in their food distribution models in response to COVID-19 physical distancing requirements. Collectively, the studies described in this PhD dissertation address knowledge gaps and may be used to inform policies and initiatives to increase food security and decrease food waste among households with low-income and organizations aimed at serving them. / Doctor of Philosophy / Food waste in the U.S. is a major challenge that impacts the environment, economy, and society. The largest amounts of food waste are generated within food retail and consumer household settings. Concurrently, food insecurity, which is defined as obtaining and having access to enough food for an adequate, nutritious diet, is also another complex food systems challenge in the U.S. Food insecurity rates are higher among people with low income and disproportionately affects ethnically and racially diverse people. The novel coronavirus (COVID-19) pandemic placed further pressure on these two food systems challenges. Diverting excess, wholesome food from retail and institutional settings to people with hunger is a preferred method to mitigate both food waste levels and food insecurity rates. The U.S. emergency food system, which is a network of food recovery organizations that aim to receive excess food from retail settings and redistribute the food to people with hunger, play a pivotal role in addressing these two challenges. This PhD dissertation described four studies that address these two challenges. While this dissertation examined food waste management, the first half of the dissertation explored this topic within households and the second half explored food waste management within food pantries, which are a critical component to the U.S. emergency food system. Study 1 utilized a systematic procedure to review previously published consumer food waste research. The purpose of this study was to examine differences in food waste attitudes and practices among consumers of various income levels. Study 2 used a survey to examine food waste attitudes and practices of households eligible for Supplemental Nutrition Assistance Program (SNAP) benefits. Study 3 explored the impact of COVID-19 physical distancing requirements on food waste management within U.S. food pantries. Lastly, study 4 explored the feasibility of food pantry staff/volunteers on implementing behavioral economics strategies, which are changes to a setting that can promote selection of a certain food item, within their food pantry. Collectively, the studies described in this PhD dissertation address knowledge gaps and may inform policies and initiatives to mutually increase food security and decrease food waste among households with low-income and organizations aimed at serving them.

Many senior citizens are surviving on minimal Social Security benefits and as a result, struggle with food security. Metrocrest Services in Farmers Branch, Texas, a suburb of Dallas, is a non-profit organization that provides several food programs to residents of the community including some programs that are specifically tailored to the needs of senior citizens. This project was to provide Metrocrest with an assessment of the food security of their senior clientele as well as other elderly residents of the Metrocrest service area and to evaluate the current senior focused programs. The project utilized qualitative research including both Metrocrest clients and residents who were not Metrocrest clients bot whose demographics were similar. The objectives were to determine the coping skills used by senior citizens in obtaining food, to assess seniors' awareness of the programs offered by Metrocrest, to discover barriers to accessing needed resources and to make recommendations of how programs could be improved or modified if needed. Through my research, I was able to present Metrocrest with a number of recommendations to improve their existing programs. I was also able to recommend some potential new programs that could be designed in conjunction with local senior centers to better serve the community.
