Eat something with complex carbs so that it will take longer to digest and yet it will keep supplying your body with energy constantly over time. Avoid high sugar foods because it will give you a shortlasting sugar rush with a longlasting downtime.
Anyways here's an article about the high fat content slowing down your brain...

Snippet:
?Fatty foods slow down the brain and impair mental function, nutrition researchers have found. But they also make people more sociable.? The researchers found ?that a high fat content in the digestive system significantly reduces alertness and affects speed and accuracy in tasks requiring sustained attention.? Even higher calorie lower fat meals did not reduce mental function when compared to a higher fat meal.
One of the researchers, Anita Wells is reported to have said; ?Carbohydrates make you feel assertive and alert . . . Although fat makes you more lethargic and impairs mental performance, we found it does make people feel more friendly.?
Edit: A suggestion would be Kashi Go Lean protein bars. My local Costco carries them and they're advertised/marketed with everything stated above. Delivers constant flow of energy, no sugar spikes, keeps you satisfied for a long time. They taste pretty decent too. Comes in a box of 24 with 3 flavors. I'm pretty sure you can find them elsewhere besides Costco.
