Accessibility is crucial to establishing and maintaining a nutritious and healthy diet. Although much of the literature on access to healthy food has focused on study areas in the Global North, the topic is of growing relevance to other regions across the globe. In Chile, where the prevalence of chronic diseases related to obesity and diet has increased, and over 50 percent of Chileans are considered overweight or obese, improving accessibility to healthy food has been an essential strategy for improving health outcomes, including the food environment. In this article, we analyze walking accessibility from homes and workplaces to open street markets and supermarkets that sell fresh fruits and vegetables and consider the role of price in the Concepción metropolitan area, the second most populated city in Chile. Results suggest that supermarkets and open street markets are distributed in a complementary way. Open street markets have a crucial role in facilitating access to more affordable products for peripheral and low-income areas. Findings also show workplaces increase accessibility in a way that is complementary to residential location.

可及性对于建立和维持营养健康的饮食至关重要。尽管许多关于获取健康食品的文献都集中在北半球的研究领域，但该主题与全球其他地区的相关性越来越大。在智利，与肥胖和饮食相关的慢性疾病的患病率有所增加，超过 50% 的智利人被认为超重或肥胖，改善健康食品的可及性一直是改善健康结果（包括食品环境）的一项重要战略。在本文中，我们分析了从家庭和工作场所到出售新鲜水果和蔬菜的露天市场和超市的步行可达性，并考虑了价格在智利人口第二大城市康塞普西翁大都市区的作用。结果表明，超市和露天市场的分布是互补的。开放的街头市场在促进周边地区和低收入地区获得更实惠的产品方面发挥着至关重要的作用。调查结果还表明，工作场所以与住宅地点互补的方式提高了可达性。
