Equitable access to healthy food is a critical challenge in urban Asia. Food safety governance promotes modern supermarkets over more traditional markets, but supermarkets are associated with unequal access to food. This study investigates how retail policies driven by food safety impact the diets of the urban poor in Hanoi, Vietnam. We do this by linking food retail infrastructures with the food shopping practices and measured dietary intake of 400 women. Our results reveal sub-optimal dietary diversity and reliance on foods sourced through traditional markets, which do not provide formal food safety guarantees. Modern channels supply formal food safety guarantees, but are mainly frequented for purchasing ultra-processed foods. The paper uncovers a conflicting duality governing food security and suggests that the public responsibility for ensuring access of the poor to nutritious and safe foods requires a more diverse retail policy approach.

低收入城市居民的食品安全和营养：探索消费政策中的社会正义困境

公平获得健康食品是亚洲城市地区的一项严峻挑战。食品安全治理促进了现代超市在更多传统市场上的发展，但是超市与获取食物的机会不平等相关。这项研究调查了由食品安全驱动的零售政策如何影响越南河内城市贫民的饮食。为此，我们将食品零售基础设施与食品购物习惯联系在一起，并测量了400名女性的饮食摄入量。我们的结果表明，饮食多样性欠佳，并且依赖传统市场提供的食品，而传统市场并未提供正式的食品安全保证。现代渠道提供了正式的食品安全保证，但主要用于购买超加工食品。
