Gustabor Phase 2 - Treating Taste Changes During Cancer Therapy: A Randomized Study Evaluating an AI- Based Nutrition Intervention

The study investigates taste disorders that commonly occur during or after cancer treatment, often leading to issues such as malnutrition and treatment discontinuation. Although many non-pharmacological recommendations exist, it is unclear which methods are suitable for which individuals. This randomized study aims to compare the effectiveness of individualized dietary recommendations (Gustabor group) with the current standard of care -general recommendations (Control group). Participants will undergo an objective assessment of taste disorders using taste strips and questionnaires. Based on the results, the Gustabor group will receive both general and specific dietary suggestions. These will be accomapnied by AI-generated recipe suggestions tailored to specific taste disorders (e.g., more cold foods in cases of metallic taste). The control group will receive the current standard: a flyer containing general dietary advice for oncology patients previously shown to be beneficial for managing taste alterations. The primary endpoint is the PG-SGA score within 12 weeks of inclusion.
