Blueberries and organic (bulk bin) oatmeal. Get the frozen ones, their cheaper and have lots of antioxidants.
Beans, rice, cheese, and guac burrittos. Several a week, alternate without the cheese. Beer. Beer. Lots of greens, spinach, mixed greens. You can put this under most food, ie: pasta on greens. You don't even know its there but your colon will.
