Sameesh,

Your first source is close to another source that I prefer to use when there is a doubt; although, it is quite generous with respect to some of the vitamins, especially Vitamin A.

The source I will use routinely is the USDA National Agriculture library database--you can search many different food items there and get a huge breakdown on the composition.

This is a *.gov website, so it should be alright for me to post it here.
