I've actually been using
www.calorie-count.com to build a diet to go along with my working out.. when you really study it, its HARD and EXPENSIVE to eat correctly in america, and its cheap and easy to eat horrible.
The funniest example I've seen was the sodium intake thing, it needs to be below 2,400 per day, and on my normal days 3,500 is easilly hit. I'm glad I live alone now, so I don't buy stuff that's bad lol
