Comments and Notes for the CN21 Release

A record with a date after 3/11/17 in the “date_added” field is a new record in the CN21 release.  A record with a date after 3/23/17 in the “last_modified” field and different from the date in the “date_added” field contains a revised value in one or more of its fields with the CN21 release.

The CNDB is no longer being released in the plain text file format.

Fields for potassium (milligrams) and vitamin D (micrograms) are now provided in the CNDB.

Data for 122 new USDA Standardized Recipes (source code 2) was added to CN21.

379 new source code 3 (food industry) food items, including items from 12 new food companies were added to CN21.

133 source code 4 (USDA Foods) items from nine food companies were added to CN21.

No changes were made to the source code 1 data because SR has not been updated since the release of CN20.

121 source code 3 (FDES) records are marked “d” in CN21 with five weights (WGHT) records and 2,181 nutrient value (NUTVAL) records also marked “d” in CN21.  Source code 1 data marked “d” in CN20, remains “d” in CN21.

For source codes 2 and 4, 443 food item (FDES) records, 526 weights (WGHT) records, and 7,088 nutrient value (NUTVAL) records marked “d” in CN20 were removed from CN21.  No source code 3 items were marked “d” in CN20, so none were removed from CN21.
