英文文献摘要：
The household production approach is used to characterize the household's preference toward nutrients in food consumption. Elasticities of substitution and Hicksian price elasticities are estimated, price- and expenditure-nutrient elasticities are calculated. Results show that protein is the most expensive nutrient, and that nutrients played an important role in determining households' food consumption.
