Nutrition plays an important role in promoting health and preventing disease, but where people live or how much money they earn can affect their ability to access or afford healthy food. Understanding the role socio-economic conditions play can help inform prevention efforts. Nutrition Policy Institute director and Cooperative Extension specialist, Lorrene Ritchie, presented at a three-day virtual National Institutes of Health workshop, “Food Insecurity, Neighborhood Food Environment, and Nutrition Health Disparities: State of the Science”. Her talk, “Food Insecurity Across the Lifespan,” provided an overview of current evidence related to racial/ethnic and socioeconomic disparities of food insecurity over the life course. All talks are free and available on-demand for online viewing.
