Yellow and orange tomatoes don't contain lycopene, but they still contain a lot of vitamin C and potassium. Yummy
My favorite source of information is a book called Wellness Foods A-Z, published by University of California, Berkeley. It contains nutrition profiles, storage tips and more, for over 500 foods - most of which could probably be considered superfoods
I like it MUCH better than Pratt's book, which ended up in my donation box.
