Two studies compared food availability and prices in large and small stores across neighborhoods of varying income levels in New Haven, Connecticut. The findings suggest that supermarket access in lower-income neighborhoods has improved since 1971, and average food prices are comparable across income areas. Despite this progress, stores in lower-income neighborhoods (compared to those in higher-income neighborhoods) stock fewer healthier varieties of foods and have fresh produce of much lower quality. Policies are needed not only to improve access to supermarkets, but also to ensure that stores in lower-income neighborhoods provide high-quality produce and healthier versions of popular foods.
两项研究比较了康涅狄格州纽黑文不同收入水平社区的大小商店的食品供应和价格。研究结果表明，自 1971 年以来，低收入社区的超市供应情况有所改善，各个收入地区的平均食品价格也相当。尽管取得了这一进展，但与高收入社区的商店相比，低收入社区的商店（stocks fewer healthier varieties of foods）库存的健康食品种类较少，新鲜农产品的质量也低得多。不仅需要制定政策来改善超市的可达性，还需要确保低收入社区的商店提供高质量的农产品和更健康的大众食品。
