In terms of nutrition info, the Precision Nutrition system/manual is really the best commercial product when it comes to a scientifically backed program, that's written in a way for a lay person to read. It's not perfect by any stretch of the imagination, but they are so far ahead of everyone else in terms of completeness.

Then some other resources that I've recommended in the past:
World's Healthiest Foods: (check out their food list in particular)
150 Healthiest Foods on Earth:

There are many others, but these are all relatively unbiased (everyone has a bias unfortunately...) so they give a reasonably neutral view.
