The six-food elimination diet (SFED), where dairy, wheat, eggs, soy, nuts, and seafood are avoided, is an effective treatment for eosinophilic esophagitis (EoE). Patient-related costs of this approach, however, are unknown. We aimed to assess the cost of and ease of shopping for an SFED compared to an unrestricted diet. A dietitian with expertise in EoE generated menus meeting dietary requirements for a week's worth of meals for the SFED and an unrestricted diet. We compared prices and the number of missing items for both diets at standard and specialty grocery stores. The average weekly price of the SFED at a standard supermarket was $92.54 compared to $79.84 for an unrestricted diet (p = 0.0001). A patient shopping at a standard grocery store needed a higher proportion of items from a second store compared to an unrestricted diet (32 vs. 3 %, p = 0.0001). The prices of the SFED and unrestricted diet using a specialty supermarket were comparable ($106.47 vs. $105.96, p = 0.81), as was the percentage of items requiring a trip to a second store (6 vs. 2 % items, p = 0.03). Shopping at a specialty grocery store increased weekly grocery costs by $13.93 (p = 0.04) for the SFED and $26.12 (p = 0.03) for the unrestricted diet. In conclusion, for patients shopping at standard grocery stores, the cost of an SFED is higher, and an SFED requires more items from a second store. These differences disappear at specialty grocery stores, but costs were significantly higher. This cost and logistical burden can inform patients when selecting dietary therapy.
六食物排除饮食法（SFED），即避免食用乳制品、小麦、鸡蛋、大豆、坚果和海鲜，是治疗嗜酸性食管炎（EoE）的一种有效方法。然而，这种方法与患者相关的成本尚不清楚。我们旨在评估与无限制饮食相比，SFED的成本以及购物便利性。一位在EoE方面有专业知识的营养师制定了符合SFED和无限制饮食一周膳食营养需求的菜单。我们比较了标准杂货店和特色杂货店中两种饮食的价格以及缺货商品数量。标准超市中SFED的平均每周价格为92.54美元，而无限制饮食为79.84美元（p = 0.0001）。与无限制饮食相比，在标准杂货店购物的患者需要从第二家商店购买更高比例的商品（32%对3%，p = 0.0001）。使用特色超市时，SFED和无限制饮食的价格相当（106.47美元对105.96美元，p = 0.81），需要前往第二家商店购买的商品百分比也相当（6%对2%的商品，p = 0.03）。在特色杂货店购物使SFED的每周食品杂货成本增加了13.93美元（p = 0.04），无限制饮食增加了26.12美元（p = 0.03）。总之，对于在标准杂货店购物的患者来说，SFED的成本更高，并且需要从第二家商店购买更多商品。这些差异在特色杂货店中消失，但成本显著更高。这种成本和后勤负担可为患者选择饮食疗法提供参考。
