  2. Responsible for: 10-13% of deaths in different parts of the WHO European Region 2-8% of health costs A strong risk factor for most prominent chronic diseases (CDs): Today, 60% of all deaths are due to CDs. By 2020, the contribution of CDs is expected to rise to 73% of all deaths. Problem: Overweight TTC’09

  3. Paradox: Undernutrition One in threepatients in general European hospitals is malnourished! • Reason: Inadequate diet lacking in certain macro- and micronutrients • Consequences:Higher complication rates (approx. 50% increase in length of stay and costs) TTC’09

  4. Measures to combat malnutrition Clinical nutrition: • Nutritional screening & assessment in hospitals and nursing homes • Artificial nutrition as medical therapy: • Very expensive • Beyond reach enteral & parenteral nutrition nutritional supplements TTC’09

  5. Our idea Web applicationfor planning meals with no or minimal artificial nutrition! TTC’09

  6. Many objectives: low cost, high seasonal and high gastronomical quality Many personal constraints that may be mutually exclusive: Energy Nutrients Ratio of certain nutrients Ratio of certain fatty & amino acids Non-nutrients (ORAC) Food pyramid Meal planning is an NP-complete problem multimodal search space TTC’09

  7. Many objectives: low cost, high seasonal and high gastronomical quality Many personal constraints that may be mutually exclusive: Energy Nutrients Ratio of certain nutrients Ratio of certain fatty & amino acids Non-nutrients (ORAC) Food pyramid Meal planning is an NP-complete problem It is expected that NO algorithm can be both correct and fast (polynomial-time) on all cases! multimodal search space TTC’09

  8. Problem translation to a knapsack problem: CO problem: Given foods of different values and volumes, the MFKP is to find the most valuable combination of foods that fits in a knapsack of fixed volumes! Evolutionary computation + linear programming for local optimization Proposed solution chromosome TTC’09

  9. Application & publication in the national guidelines and recommendations Publication in a peer-reviewed journal Cooperative research project for SME Presentation to an international group of experts (EuroFIR, ESPEN): FP7 project proposal Performed researchsteps TTC’09

  10. Performed steps: Presentation given to a group of diabetes experts who supported the idea The Slovene patent (SI 22693 A) Looking for an industrial partner! Personalized nutrition scale First extension Web application for meal planning TTC’09

  11. Mobile application for informing consumers about nutritional value of food items: Performed steps: National research project Looking for a mobile operater and insurance company! Second extension Web application for meal planning TTC’09

  12. Food & physical activity diary for data mining and knowledge discovery Performed steps: Bilateral project Dietary knowledge ontology Third extension Web application for meal planning TTC’09

  13. Steps & decisions to be done Related mandatory activities: • Up-to-date food composition data & reference values • Research work • Permanent education and training • Human-experts as active participants in the social network TTC’09
