The USDA has released their nutrient database in convenient searchable format for Windows PCs and PDAs. The nutrients for more than 6,000 food items are listed. The database was already available online, but now you can have your own local copy. The PC version has better filtering with support for “not” and filters for various food types, such as sweets, snacks, baby foods. Various name brand products are included. Although the database is representative of the typical American palate, support for non mainstream foods is not entirely lacking. For example a search on “mushrooms” brings up data for “oyster”, “Crimini”, “enoki”, “portabello”, cooked and dried “shiitake.” Wasabi is also listed. I found listings for various game meats (elk, buffalo, and yes, muskrat, squirrel, and raccoon) but nothing under “frog”.
