NAME

update-nut - create or upgrade NUT database

SYNOPSIS

update-nut

DESCRIPTION

Download the full ascii version of the USDA Nutrient Database, available from http://www.ars.usda.gov/nutrientdata or from http://nut.sourceforge.net, and unzip it in some directory.

Then, run "update-nut" to create or upgrade the NUT code in the SQLite database that runs the application in the same directory as the USDA Nutrient Database. If upgrading, you have to be in the same directory as the "nut.db" file. After this step, "update-nut" is not required for anything. Updating the NUT code with "update-nut" is independent of updating the USDA database, although it is certainly possible that the USDA could change the format of their tables, so that a later version of "update-nut" would be required in order to read their tables or display new nutrients. The main idea is that your personal data is permanent, even though the application code and USDA tables can change as necessary.
