Brain Food For Studying

I need to buy some brain food for studying for the bar. Something besides the HoHos and DingDongs in the vending machine at work. I really had to decide whether I wanted a HoHo or a DingDong today. (I decided on a HoHo.) I hear that blueberries are good brain food. I picked some up at the grocery yesterday. I will eat them with vanilla yogurt and granola. Yum. Now I need to inch towards this kind of eating and away from the junk food. Well, maybe a little at a time.
