Food Security Among South Asian Americans: The Role of Availability, Affordability, and Quality of Culturally Appropriate Food

<b>Background:</b> South Asian Americans (SAA) are one of the fastest-growing immigrant groups in the U.S. and face significant health disparities, particularly regarding chronic diseases like diabetes, hypertension, and cardiovascular disease. Dietary patterns play a crucial role in these disparities, with acculturation to Western diets linked to poorer health outcomes. Despite this, the impact of food insecurity on dietary habits among SAAs remains underexplored. This study aims to examine the availability, cost, and quality of ethnic food items and how food insecurity influences dietary practices in Southern California's SAA population. <b>Methods:</b> The study was conducted in San Bernardino County, California, with field data collection focused on five South Asian ethnicity-specific grocery stores and three Western grocery stores. We assessed the availability and cost of key ingredients for commonly prepared SAA dishes. Additionally, focus group interviews were held with South Asian immigrants to understand food insecurity challenges and dietary adaptations. <b>Results:</b> The study found significant disparities in food availability and cost between SAA-ethnic grocery stores and Western stores. SAA stores were less accessible and more widely dispersed, with an average distance of 10 miles between them. While ingredients like ginger paste and cumin powder were available in both types of stores, items such as ghee, fenugreek seeds, and black gram were harder to find in Western stores. Focus group participants noted that ethnic foods, especially vegetarian ingredients, were more expensive than Western alternatives, leading many to substitute traditional meals with cheaper, less nutritious options. Participants also raised concerns about the poor quality of items in ethnic stores, such as expired produce, which further limited their food choices. <b>Conclusions:</b> Food insecurity, driven by limited availability, high cost, and poor quality of ethnic foods, poses significant challenges to the SAA community's diet and health. Addressing these barriers could improve food security and health outcomes among SAA immigrants.
