[Estimating and forecasting of the minimum consumption expenditure when meet with the needed nutrients in 8 provinces in China].
OBJECTIVE
The purpose of this study is to estimate and forecast the minimum consumption expenditure on food of 8 provinces using linear programming model.


METHODS
Analysis was based on the food data of 2000 of the China Health and Nutrition Survey. The linear programming model's target population was 18 - 49 years old adult with different physical activity level. The mathematical model was established and functioned by GAMS.


RESULTS
It was not a high consumption expenditure on food of 8 provinces when meet with the 13 nutrients and the required amount of food, even in the year of well-to-do.


CONCLUSIONS
We should improve the household' s dietary quality by following the viewpoint of lowest cost but enough nutrients in different income level. The study suggested that we should tell the residents about the lowest cost when we engage nutrition education.
