Check out the USDA National Nutrient Database at their website
to find the nutrient info for food that you may not be able to find otherwise. I've used this a few times to verify the info I had available. The nutrient info provided is easy to read and very, very extensive.
This website http://www.nal.usda.gov/fnic
is relatively easy to use and can be invaluable if you are looking for a particular nutrient in a food that you may not be able to find anywhere else.
