Area of Science:

  • Nutritional Science
  • Computer Science
  • Cardiovascular Health

Background:

  • Personalized lifestyle counseling is crucial for preventing cardiovascular diseases.
  • Automated tools can support tailored dietary recommendations.

Purpose of the Study:

  • To describe the results of MenuGene, an automated menu generator within the Cordelia web-based lifestyle counseling system.
  • To evaluate MenuGene's effectiveness in generating personalized menu plans for cardiovascular disease prevention.

Main Methods:

  • MenuGene employs genetic algorithms to construct weekly menus for web users.
  • Nutritional objectives are based on personal medical data and general guidelines.
  • The menu structure is modeled in a multilevel format.

Main Results:

  • The genetic algorithm successfully generated menus adhering to strict nutritional constraints across meal, daily, and weekly levels.
  • A rule-based assessment effectively adjusted nutritional component occurrence, enhancing menu variety and harmony.

Conclusions:

  • A unified method can generate weekly, daily, and meal-level menu plans that meet nutritional requirements.
  • Splitting the problem into sub-problems allows for the creation of well-assorted and nutritionally sound menu plans.
