Problem: Overweight
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.

Paradox: Undernutrition
One in three patients 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)

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

Our idea
Web application for planning meals with no or minimal artificial nutrition!

Meal planning is an NP-complete problem
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
multimodal search space

It is expected that NO algorithm can be both
correct and fast (polynomial-time) on all cases!

Proposed solution
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
