Good question.
Here are the foods that I reccomend:
1. peanut butter, but not too much (as peanuts are potential carriers of the carcinogenic mold aflotoxin)
2. nuts--almonds, walnuts (good source of omega 3 fatty acid, which has a myriad of health benefits)
3. yogurt (actually better than milk)
4. milk (has casein and whey, too excellent protein sources)
5. eggs
6. cottage cheese
7. oatmeal
8. brown rice, white rice (try to eat brown rice, too, but white rice is alright once in a while too)
9. pasta
10. tuna (limit your tuna intake due to environmental contamination involving mercury from coal plants)
11. chicken
12. cheese
13. beef, buffalo, bison
