Existing studies suggests that immigrants' dietary quality often declines over time after they move to the U.S., despite public and private efforts to provide immigrants and refugees to the U.S. with nutritional resources. Drawing on two interview-based studies with immigrants (n = 30) and refugees (n = 8) in North Carolina, we find that these immigrant/refugee communities often have healthy food traditions from their home countries that they want to maintain, but they lack guidance about how to navigate the U.S. food system in order to do so. Our findings question the notion that "good nutrition" is a universal concept; we argue that by focusing solely on the nutritional components of food, rather than approaching dietary behavior holistically, service providers exacerbate the challenges that immigrants and refugees face in continuing healthy food traditions in the U.S. Our analyzes extend previous research on food socialization by specifically examining the nutrition socialization process of immigrant and refugees, furthering our understanding of how and why immigrants' diets change over time.
