OVERVIEW
NUT allows you to record what you eat and analyze your meals for
nutrient composition. The database included is the USDA Nutrient
Database for Standard Reference, Release 22.
This database of food composition tables contains values for
calories, protein, carbohydrates, fiber, total fat, etc., and
includes all the nutrient data in the USDA database, including the
Omega-6 and Omega-3 polyunsaturated fatty acids. Nutrient levels are
expressed as a percentage of the DV or Daily Value, the familiar
standard of food labeling in the United States. The essential fatty
acids, Omega-6 and Omega-3, are not currently mentioned in these
standards, and a reference value has been supplied.
You may search this list of foods and view nutrient values for
different serving sizes; you may also rank foods in order of level
of a particular nutrient. You may change the daily calorie level to
correspond to your personal metabolism, and the levels for fat,
carbohydrates, fiber, and protein are automatically adjusted. You
may customize the ratios of carbohydrates to protein to fat to suit
your personal regimen. You may add your own recipes to the database,
by creating them from the foods in the database. You can also add
foods from the information on commercial food labels. The program is
completely menu-driven and there are no commands to learn.
INSTALLATION
Note: NUT can modify your prior release database files automatically, from
release 8.0 forward. Just follow the steps below and make sure that
the Makefile points to your current ".nutdb". NUT will read in
your recipes and match your meal records to a changed food database,
or else make other changes the new version requires; however, NUT
may be incapable of preserving your former personal options or retaining
meal foods that do not exist in a changed USDA database, so it is a
good idea to make a copy of your "meal.db" file before proceeding.
1) Untar the archive:
tar xvzf nut-15.5.tar.gz
cd nut-15.5/
2) Consider where you want to put the raw data files. In the Makefile, find
the line:
CFLAGS= -O3 -s -Wall -DNUTDIR=\".nutdb\" -DFOODDIR=\"/usr/local/lib/nut\" -ansi -pedantic -fno-inline
You may redefine "FOODDIR" as shown on the Makefile line, and then
create the directory if necessary, and move the contents of the "raw.data"
directory to that directory.
mkdir /usr/local/lib/nut/
mv raw.data/* /usr/local/lib/nut/
The personal database subdirectory "NUTDIR" is relative to your home
directory. If you wish, you may change it to whatever you
want. It will be made automatically the first time the program runs,
if you are not upgrading.
3) Issue the command "make".
4) If all goes well, move the "nut" executable where you want it, and move
"nut.1" to your favorite man directory.
mv nut /usr/local/bin/
mv nut.1 /usr/local/man/man1/
5) When you run NUT the very first time, it will take a minute or so to
come up because it is reading the file "sr22.nut", and creating the files
"food.db", "meal.db", "theusual.db", and "OPTIONS.txt". The USDA-format
files "FOOD_DES.txt", "NUT_DATA.txt", and "WEIGHT.txt" contain the
data for recipes and edits to the database. The USDA-format group in the
directory defined as FOODDIR are for installation-wide changes and the
changes that come in the NUT distribution. The group in the user's
database directory are personal changes to the database. Both
groups will be read only if there is no "food.db" when the program
starts, unless you are upgrading to a release which rebuilds the food
database and re-indexes the meals to it.
The source for the food database is:
U.S. Department of Agriculture, Agricultural Research Service. 2009.
USDA National Nutrient Database for Standard Reference, Release 22.
Nutrient Data Laboratory Home Page, http://www.ars.usda.gov/ba/bhnrc/ndl
When not specified, all PUFAs except 18:2, 20:3, 20:4, 21:5, and 22:4 are
considered to be omega-3; the database does not yet distinguish between
omega-6 and omega-3 for many foods. The omega-6 and omega-3 totals may be
overstated for foods which contain significant trans- fats, such as those
which contain hydrogenated vegetable oils.
Note: There are no DVs for the Omega-6 and Omega-3 polyunsaturated fatty
acids. Reference values shown may be more or less than your personal
needs. Under the Personal Options menu item is a sub-item for causing
the program to look for absolute amounts rather than the default
percentage of calories, or to change the way the program computes
values after an analysis reset.
