Area of Science:

  • Public Health Nutrition
  • Food Science
  • Operations Research

Background:

  • Large-scale supplementary feeding programs face challenges in providing diverse, acceptable, and nutritionally complete foods.
  • The Indian Supplementary Nutrition Program (SNP) offers dry take-home rations or hot cooked meals but requires optimization tools for local recipes.

Purpose of the Study:

  • To develop a linear programming (LP) model for optimizing food provisions in supplementary feeding programs.
  • To ensure diverse food options meet program guidelines and budget constraints using locally available ingredients.

Main Methods:

  • An LP algorithm was employed to generate optimized dry take-home rations or weekly hot cooked meal menus.
  • A comprehensive food database was created from a nationwide survey to ensure recipe diversity and adherence to beneficiary guidelines.

Main Results:

  • An interactive web-based application was developed to optimize feeding programs at any population scale.
  • Optimized diets met SNP guidelines for nutritional completeness and diversity, but costs were approximately 25% higher than current allocations.

Conclusions:

  • The developed optimization model can create contextual supplementary feeding program diets meeting essential nutrient needs.
  • Achieving appropriate food diversification within large-scale feeding programs necessitates increased budget allocations.
