Nutrient Database
The NutrientDB is a database containing over 6,000 foods and their complete
nutritional breakdown. The database is compiled by the U.S. Dept of Agriculture
(USDA) and is freely available at their website as a set of
ASCII text files.
In keeping with
this spirit of free information and open source software, this website has taken
this freely available data and developed a web based application to access it.
The code is written in PHP 5 and uses a MySQL 4.x backend database.
