Recipe websites are becoming increasingly popular to support people in their home cooking. However, most of these websites prioritize popular recipes, which tend to be unhealthy. Drawing upon research on visual biases and nudges, this paper investigates whether healthy food choices can be supported in food search by depicting attractive images alongside recipes, as well as by re-ranking search results on health. After modelling the visual attractiveness of recipe images, we asked 239 users to search for specific online recipes and to select those they liked the most. Our analyses revealed that users tended to choose a healthier recipe if a visually attractive image was depicted alongside it, as well as if it was listed at the top of a list of search results. Even though less popular recipes were promoted this way, it did not come at the cost of a user's level of satisfaction.
食谱网站在支持人们家庭烹饪方面越来越受欢迎。然而，这些网站大多优先推荐受欢迎的食谱，而这些食谱往往不健康。本文借鉴了关于视觉偏见和助推的研究，调查在食谱旁边展示吸引人的图片以及对健康相关的搜索结果进行重新排序，是否能在食物搜索中支持人们做出健康的食物选择。在对食谱图片的视觉吸引力进行建模后，我们让239名用户搜索特定的在线食谱并选择他们最喜欢的食谱。我们的分析表明，如果食谱旁边配有视觉上吸引人的图片，或者它列在搜索结果列表的顶部，用户往往会选择更健康的食谱。尽管通过这种方式推广的食谱不太受欢迎，但这并没有以用户的满意度为代价。
