Outline of Final Research Achievements

Using a linear programming model, the present study explored the optimal food intake patterns and diet cost that meet the nutrient recommendations of the Dietary Reference Intakes while incorporating typical Japanese food selections.
Achieving nutritional goals required minor modifications of existing diets in older groups (50-69 years), while major modifications were required to increase the intake of refined grain, vegetables, soy products and reduced-fat dairy products, and to reduce the intake of salt-containing seasonings in younger group (20-49 years). Across all sex and age groups, diet cost from the current eating habits needed to be increased by 7-18% to meet nutrient recommendations.
