In this paper, we describe a formative study to learn how one chronically ill population thinks about food, mentally organizes food, and interprets consumption-level icons. We found that many participants let their pride influence their choices, resulting in preferred interfaces that they could not accurately interpret. The results indicate that participants organized food in similar ways, had difficulty reading from their preferred consumption-level icons, and wanted to combine multiple interface designs when searching for food.
