As I posted in the other thread you started this morning, the best place to start is by setting up your profile in FitDay and start logging food. Have you done that yet? Once you do, you can look at your food log and see what is good to eat and what is not.
Basically, with some personal variation, eat fruits, veggies, lean protein (chicken, lean beef, lowfat dairy), and complex carbs, as well as healthy (monounsaturated) fats (whole wheat, etc.). That's very simplified. Stay away from simple carbs (things made from white flour, sugar).
Google can be your best friend.
