Nutrition facts label

My question: I have two children who have really gotten into reading the FDA-required "Nutrition Facts" label that appears on packaged food. In particular, my son (age 7) now continually reads the labels and tries to decide "which is healthier?" The problem? The nutrition label is only on things that have packages, which are more likely to be processed foods. Is there a website or other resource that gives you the nutrition facts label for generic (and healthier) things like broccoli, watermelon, apples, dried organic lentils sold in bulk, and the like? I've searched around, but can only find this information in disparate places, and nothing as nifty-looking as that label!! Thanks, Alice!
