At “Positive Nutrition, Mediterranean and Nordic Dietary Models: Innovation and Sustainability for Future Food Systems” in Copenhagen on 28 October, Pietro Paganini explored how the principles of the Mediterranean Diet can inform modern prevention: connecting nutrition, movement and well-being with education, scientific innovation and individual choice.
In a nutshell
- The Mediterranean Diet is more than a selection of foods: its broader value lies in moderation, physical activity, social relationships and habits that can adapt to individual needs.
- Prevention requires more than product classifications: labels, taxes and reformulation should be assessed against health outcomes and supported by education and healthier living environments.
- Personalized prevention can make knowledge more useful: AI and wearable technologies offer opportunities to translate information into practical guidance, while preserving individual judgment and autonomy.
Rediscovering the Mediterranean Method
Why do the countries associated with the Mediterranean Diet continue to face major challenges from obesity and diet-related diseases?
While the Mediterranean Diet remains widely celebrated, the circumstances that sustained it have changed. Food is more accessible and convenient, daily routines require less physical effort, and shared meals increasingly compete with fragmented schedules.
For Paganini, responding to these changes requires looking beyond traditional recipes. The ancient Greek concept of diaita, understood as a way of life, offers a broader perspective: food, movement, rest and the surrounding environment belong to the same conversation.
The Mediterranean method draws on this philosophy. Moderation requires understanding quantities, frequency and context, while balance involves adapting habits to needs that change throughout life.
Nutrition, Movement and Well-Being
Paganini identified three interconnected dimensions of prevention: nutrition, movement, and psychological and social well-being.
In nutrition, variety, portions and frequency help explain how individual foods fit within an overall diet. Physical activity extends beyond structured exercise to walking, cycling and everyday movement. Sleep, stress, relationships and the pleasure of sharing meals complete this broader understanding of health.
These habits also depend on the conditions in which people live. Schools, workplaces, transport systems and urban design can make active routines and healthier choices easier or harder.
Prevention therefore needs to address both individual capabilities and living environments. Advice becomes useful when people have the knowledge and practical opportunities to apply it.
From Food Labels to Informed Choices
To illustrate his approach to nutrition policy, Paganini used a simple metaphor: traffic lights and roundabouts.
Traffic lights provide standardized instructions. Roundabouts establish shared rules while requiring people to observe their surroundings and exercise judgment. Applied to prevention, the comparison highlights the importance of helping individuals understand their choices.
Food labels, fiscal measures and reformulation can influence purchasing decisions and product composition. However, changes in purchasing behavior do not automatically demonstrate lasting improvements in health. Their effects depend on substitutions, overall dietary patterns and individual circumstances.
Paganini called for policies to be evaluated against meaningful health outcomes, alongside costs and unintended consequences. Population measures and personalized approaches can complement one another, supported by sustained investment in nutritional literacy.
Education as a Foundation for Prevention
Understanding food takes more than access to nutritional information. It requires the ability to interpret that information and use it in everyday situations.
Paganini argued that nutrition and lifestyle education should begin in schools and continue throughout life. Learning about portions, variety, movement and sleep can help people develop sustainable habits while maintaining a positive relationship with food.
Healthcare professionals also need practical training that connects these dimensions. Educational initiatives should have continuity, adequate resources and measurable outcomes, giving prevention a stronger foundation before disease emerges.
AI and Personalized Prevention
Artificial intelligence, precision nutrition and wearable technologies could help translate general recommendations into guidance that better reflects individual needs.
By connecting information about diet, activity and sleep, these tools may help people understand patterns in their daily lives and participate more actively in prevention. Their reliability, accessibility and long-term health benefits still require rigorous evaluation.
Paganini also raised a question about their purpose: will technology strengthen individual understanding, or become another system of instructions?
Digital tools should support informed decisions and preserve meaningful control over personal data and choices. Prevention must leave room for pleasure, flexibility and different ways of living.
The Mediterranean method offers a guiding principle for this ambition: help people develop the knowledge and judgment to find a balance that works in their own lives.
