Mobile health applications (apps) have been shown to be effective for improving eating habits. However, most of the existing apps rely on calorie and nutrient counting which have several limitations including the difficulty in sustaining long-term use, inaccuracy, and the risk of developing eating disorders. We designed and developed a mHealth framework for nutritional behaviour change, integrated into the CarpeDiem app, that focuses on the intake of key food groups which are known to have a higher impact on health indicators instead of the intake of nutrients. This framework is mainly based on a gamified system that delivers personalized dietary missions to the user and provides motivational recommendations that help the user to achieve these missions. Its design was guided by an evidenced-based theory of behavioural change, the HAPA model, and it is also characterized by the personalization of the system and the use of a recommender system based on advanced artificial intelligence techniques. Overall, the approach used in the present app could foster a sustained improvement of eating habits among the general population, which is the main challenge of dietary interventions, decreasing the risk of developing the chronic diseases associated with unhealthy dietary habits.
移动健康应用程序（apps）已被证明可以有效改善饮食习惯。然而，大多数现有的应用程序依赖于卡路里和营养计数，这存在几个限制，包括难以长期使用、不准确和饮食失调的风险。我们设计并开发了一个用于营养行为改变的移动健康框架，集成到 CarpeDiem 应用程序中，该框架侧重于摄入关键食物组，这些食物组已知对健康指标有更高的影响，而不是摄入营养物。该框架主要基于一个游戏化系统，为用户提供个性化的饮食任务，并提供激励性建议，帮助用户完成这些任务。它的设计是由行为改变的循证理论 HAPA 模型指导的，其特点还包括系统的个性化和使用基于先进人工智能技术的推荐系统。总的来说，本应用程序中使用的方法可以促进普通人群饮食习惯的持续改善，这是饮食干预的主要挑战，可以降低与不健康饮食习惯相关的慢性疾病的风险。
