The 18th Panhellenic Congress of Nutrition & Dietetics took place at the Athens Concert Hall from 4–6 December 2025, bringing together scientists and professionals to discuss the latest developments in nutrition under the central theme “Bridging Research and Practice.”
The Congress covered topics ranging from alternative proteins to eating disorders, through lectures, workshops, and roundtable discussions.
During the session “Co-Creating Health: Participatory Research with Cancer Patients on Nutrition and Mental Resilience”, held on Friday, 5 December in Hall MC3, participants included Andrea Paola Rojas Gil, Associate Professor of Biology – Biochemistry and Director of the Laboratory of Basic Health Sciences at the University of Peloponnese, a close KAPA3 collaborator in the field of nutrition, with the topic “Nutrition as a Tool to Support Treatment and Wellbeing: Comparison of Co-Design Programs for Oncology Patients in Greece and Colombia”; Evagelia Bista on behalf of KAPA3 with “Nutrition as a Social Determinant of Health: Inequalities, Education, Environment and Policies”; and Ioanna Sideri with “Mental Health and Strategies for Empowerment and Resilience”.
Nutrition as a Social Determinant of Health
Evagelia Bista emphasized that nutrition is not merely a personal choice but one of the most critical social determinants of health, directly affecting the prevention, progression, and quality of life of oncology patients. Nearly half of people worldwide lack access to healthy food, and socio-economic inequalities determine who can follow a nutritious diet. Greece is no exception: the economic crisis, the high cost of healthy foods, and the turn towards cheap, highly processed options have worsened the situation.
Key points highlighted in the presentation included:
-
Income, education level, and food availability determine dietary quality, with low-income households experiencing higher rates of obesity and chronic diseases.
-
A shift from the Mediterranean diet towards Western-style options due to economic and social factors.
-
A double burden for vulnerable populations: undernutrition and obesity coexist, particularly affecting those facing food insecurity.
-
Impacts on oncology patients: adequate nutrition is crucial for treatment tolerance, recovery, and quality of life, yet many patients face financial and treatment-related barriers.
Ms. Bista presented KAPA3’s actions with a focus on nutritional support and the participatory approach applied in online Experiential Sessions, conducted in collaboration with the University of Peloponnese. These sessions continue a series dedicated to holistic care for body and mind, emphasizing both nutrition and mental health for oncology patients and their caregivers.
KAPA3 underlines that nutrition cannot be seen as an individual behavior alone but as the result of social, economic, and environmental factors. Reducing inequalities and ensuring access to healthy food for all is essential for better health outcomes, especially in oncology care.
