title: A simple and quick method to evaluate the influence of food price policy on population-based nutrition status and related nutrition intervention.
abstract: Food price policies have a major influence on population food choice and nutritional status, especially for low-income families. Therefore, simple and quick methods to evaluate their influence is desirable. Consistent with nutritional rationality and economical feasibility, a mathematical model was developed by Linear Programming to appraise the influence and rationality of the subsidization of egg and pork in Tianjin, using the data about food varieties and their prices in Tianjin in 1990. It was found that food subsidism to influence choice was not rational for improvement in nutritional status of low-income families. The concept, of "food choice space" was developed and its implications for nutrition intervention explored. The model developed can be used to judge the nutritional effect of food price policies and provide baseline data for nutrition intervention.
