Eating habits are influenced by emotional factors. Therefore, persuasion to change bad habits should integrate both rational and emotional strategies appropriately. This article describes a prototype system aimed at simulating user-adapted persuasion dialogues in the healthy-eating domain. They describe how they collected and analyzed a corpus of messages in the domain and compared the persuasion strength of alternative strategies in this corpus. Their prototype system reasons about the participant's beliefs to select an appropriate strategy for a given context, and translates the selected strategy into a natural-language, rhetorically coherent text. This article is part of a special issue on argumentation technology.
