If a recall was coded reliable, but incomplete, (DRPSTAT=2) the meal numbers may not be consecutive; information is reported for meals that were reported during the dietary interview. Meal numbers are not sorted by the time of day. DRPFN Food number Every food has a food number. Foods are numbered within meals. If the recall was coded complete and reliable (DRPSTAT=1), the first food in each meal has a food number=1, and the other foods reported in the same meal are numbered consecutively. If the recall was coded reliable, but incomplete, (DRPSTAT=2) the food numbers may not be consecutive; information is reported for all foods that were reported by the respondent. DRPCN Component number Foods are comprised of one or more components. An example of a single component food is a slice of bread. A sandwich is an example of a multiple component food or combination food; in this example, the component foods consist of bread and sandwich filling components. If a recall was coded reliable and complete (DRPSTAT=1), all components are numbered consecutively within a given food; the component numbering sequence for the first food begins with component number=1 and increases by one for each additional component in the food. The numbering sequence is repeated for each additional food reported. If the recall was coded reliable, but incomplete,(DRPSTAT=2) the component numbers may not be consecutive; information is reported for the components that were reported by the respondent. DRPIN Ingredient number Component foods may have ingredient records associated with them. The first ingredient of a component has ingredient number =1; ingredient numbers increase by one for each additional ingredient of the component food. Variable ingredients are reported in the Variable Ingredients File. DRPICODE Ingredient food code An ingredient food code was assigned to all ingredients that were used to prepare recipe foods. Most of the ingredient food codes were USDA Survey Nutrient Data Base food codes; NCC food codes were used to code some ingredients. NCC nutrient values were used for the ingredients that were assigned NCC food codes. Text descriptions for the ingredient food codes are listed in a look-up table called "Codebook". Blank Blank values in the DRPICODE field denote that one or more variable ingredients were omitted during food preparation. The ingredient food identification code (DRPINGID) provides a unique food identification code for variable ingredients that were omitted during food preparation; text descriptions for DRPINGID are found in the look-up table called "IDCODE". DRPINGID Ingredient ID code A unique 4-digit code that provides additional descriptive information about the ingredients that were used to prepare recipe foods. All ingredient ID codes have a corresponding text description found in the look-up table called "IDCODE". DRPCOMM Brand ID or fast food code All brand name and fast food restaurant items reported during NHANES III were assigned a 5-digit DRPCOMM. DRPCOMM codes are linked to a table of commercial foods text descriptions in the look-up table called "Brands". DRPVIDC Variable ingredient default code The DDC System assigned variable ingredients to foods automatically when the respondent was unable to specify the ingredients that were used to prepare recipe foods. Each DRPVIDC has a text description associated with it in the data file documentation.
