Household Daily Food Master File
The CHNS Household Daily Food Master File (NUTR1) contains information regarding the household foods that were obtained, consumed and discarded during the CHNS Diet Survey. As a longitudinal file, this file contains multiple years of data for each household. A household can have from 1 to 7 years of data as designated by the WAVE variable which contains the survey year, 1989, 1991, 1993, 1997, 2000, 2004 or 2006. And each year will normally have multiple foods as designated by the FOODCODE variable.
This file consolidates 7 separate diet survey files:

Some variable names have been changed to be consistent across all survey years and not all variables contain information for all years. See the following Variable Name Mapping document.
Some of the older household IDs are no longer current, as all members have moved to different households. If there is a need to merge household level data with individual level data, you will need to use the individuals previous ID depending on the survey year.
NOTE: Food amounts were collected in jin (500 grams) from 1989 through 2000. In 2004, food amounts were collected in grams.
