Description:

The file NDB_SR10.MDB is a Microsoft Access relational database, comprised
of over 5200 individual food items, ported from flat files released from
the USDA.  These flat files (AH8-01.DAT through AH8-21.DAT) were ftp'ed from
the University of Maryland, and converted using a C program (source available
from the author) and custom Microsoft Word macros.

The author takes no responsibility for the accuracy of the port, nor for the
content of the database itself.

The database consists of four tables:

   CATEGORY
      A list of categories that the food items are arranged into

   DESCRIP
      The full text description of each food item

   NDB_SR10
      The food item data, consisting of:
         Category
         Food item number
         Short Description
         Common household measure 'E', e.g. "1 cup"
         Number grams in 'E' measure
         Common household measure 'F', e.g. "1 pound"
         Number grams in 'F' measure
         % refuse
         Amount of nutrient #203 in 100g
         Amount of nutrient #204 in 100g
         ... <80 nutrients total>
         Amount of nutrient #654 in 100g

   NUTRIENT
      The name for each nutrient and nutrient measure (e.g., milligrams)

No joins or relations for the tables have been defined in the database
as of yet, but are intuitively obvious, and are left for the interested user.
