title: [Estimating and forecasting of the minimum consumption expenditure when meet with the needed nutrients in 8 provinces in China].
abstract: 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
