 The file "SNKSWT.DAT" contains updated values for Snacks and Sweets
 which were published in Agriculture Handbook No. 8-19.  These data
 will also be included in Release 10 of the USDA Nutrient Data Base
 for Standard Reference, which will be released in 1992.  However due
 to the high level of interest in these new data on fresh pork, we
 are releasing them early through the Nutrient Data Bank Bulletin Board.

 To update an earlier release of the USDA Nutrient Data Base for Standard
 Reference you will need to perform the following steps:

     1.  Delete the items listed in the first field (columns 1-5) of
         the file "SNKSWT.MCH" from your current version of the data base.
         The second field (columns 7-11) of the file indicate the new
         NDB numbers which you will need to use in any programs
         accessing these data.

     2.  Add all items in the Snacks and Sweets data file to the data
         base file that you edited or created by performing the above step.

 The record containing the nutrient number 000 contains a 20 character
 abbreviated description of the item.  This description is found in columns
 9-28.  Because of its size, this description may not contain all food
 identifiers.  Complete descriptions are included in the coding manual.

 Format:
 
 This file is in free format, with fields delimited by commas.  It consists
 of two record types.  The first record for a food (Header record) contains:

        Field
       Number       Description

         1          Food item number
         2          Short description
         3          Count of nutrient records
         4          Description of the first household measure
         5          Gram weight of the edible portion of the
                    first household measure for this food
         6          Description of the second household measure
         7          Gram weight of the edible portion of the
                    second household measure for this food
         8          Percent refuse

 The remaining records for a food (Nutrient records) contain, in order:

        Field
       Number       Description

         1          Nutrient number
         2          Mean value per 100 grams edible portion
         3          Standard error
         4          Number of observations

 Notes on fiber.  Three types of fiber are reported on the Nutrient Data Base
 for Standard Reference:  Crude fiber (nutrient 206); insoluble dietary fiber,
 nutrient 273, determined by the neutral detergent fiber method (NDF); and
 total dietary fiber (TDF), nutrient 291, determined by the method of the
 Association of Official Analytical Chemists.  Data for all three measures of
 fiber may not be present for each food item.  When more than one measure of
 fiber is present, the values were not derived from the same samples.
 Differences between NDF and TDF values reflect not only differences due to
 methodology but also to variations in cultivars, growing areas, growing years,
 and laboratories.  For most items, NDF and TDF values are based on a limited
 number of analyses.  A note of caution: the difference between NDF and TDF
 values is only a rough estimate of the soluble dietary fiber and should
 never be used as an analytical value.
