Evaluation of the Specialized Clinic for Nutrition and Mental Health: A Pilot Study

The goal of this observational pilot study is to learn how personalized nutrition-focused care can help people with mental and psychosomatic health problems. This study takes place in Europe's first outpatient clinic that focuses on how diet affects mental well-being. The main questions the study aims to answer are: Does care at this clinic help lower participants' stress levels over one year? Do participants report better mental health, resilience, and quality of life during the study? Are improvements in mental health linked to changes in diet and blood markers like inflammation? Participants will: Fill out online questionnaires every 3 months over one year. These ask about stress, physical symptoms, quality of life, diet, and satisfaction with care. Give small blood samples during their regular clinic visits. These samples will be checked for common health markers such as inflammation. This study will help researchers understand whether nutrition-focused care can support mental and physical health, and whether this approach should be tested in larger future studies.
