Abstract

The rapid urbanization and income growth have led to changes in the global food systems and nutrition transition in many developing countries. The prevalence of obesity and dietary-related diseases has become an urgent issue in developing national health policies. Taiwan is a rapidly aging society and its highest prevalence of obesity is observed in adults above 65 years old. This paper aims to find the optimal age- specific dietary intake pattern for both sexes based on the data from Nutrition and Health Surveys in Taiwan (NAHSIT). Goal programming approach is adopted to minimize the gap between observed diet and the dietary recommendation intakes (DRIs) from the public health authorities. Food consumption constraints is added to prevent diet plans from including unreasonable pattern and to minimize impacts on household food expenditures. Our result suggests that lack of calcium intake is a common problem for all age groups and both sexes in Taiwan and a shift from meat and oil products to more fish, nuts and vegetables is required. The age- and gender-specific results also show how goal programming modelling can be used to translate the DRIs into economically acceptable food plans.
