I found this great article:

ADHD Diet: WHAT TO EAT TO OPTIMIZE THE ADHD BRAIN
Just as some foods make the brain "foggy," other foods can enhance and optimize brain performance. Here are some things to eat to feed the ADHD brain...

• FOR BREAKFAST SERVE HIGH PROTEIN, LOW CARBOHYDRATE MEALS. Say, “Good-bye,” to Breakfast cereals and milk. Breakfast cereals are mostly carbohydrate and sugar, which is a bad combination for the ADHD brain. And many children are allergic to milk. So the classic American breakfast of cereal with milk is a bad idea.
  Instead, serve 60% to 70% Protein and 30% to 40% Carbohydrates for Breakfast. Eggs, breakfast meats, and some toast would be fine. Other meals of the day could be 50% Protein and 50% Carbohydrate.
• PROTEIN SUPPLEMENTS might be needed to get the added protein for Breakfast. They are often very helpful in the afternoon as well. Here is our favorite recipe for a Protein Shake: a) Make a cup of coffee with a flavor that you or your child will like (yes, I know I'm breaking my own rules here, as these flavors will have some sugar, but I'm trying to get your kid to actually drink the thing, and also get some caffeine mixed with the protein.). Pour the hot coffee into a blender with about 6 oz of ice. Turn on the blender for a bit.
  b) Add a good quality protein powder. There are many good ones available. If you can't find one that you like, ask at your local health food store. Get protein powders that are mostly protein and very little carbohydrate. Add between 15 and 20 grams of protein to the cold coffee in the blender.
  c) Turn on the blender again.
  d) Drink it up.
  This protein shake is helpful for a lot of people. For many small kids, and many adults, this recipe works about as well as a small dose of Ritalin (100 mg of caffeine is roughly the same as 5 mg of Ritalin). So many who might just take a small dose of Ritalin might get away with just doing this.
  Don't forget, though, that even caffeine can have some side effects. Every once in a while we find someone that has problems with the caffeine in the coffee. Usually, though, the caffeine in the coffee helps the person to focus better. The protein helps to feed the brain. If you find this helpful, have one with Breakfast, and one around 3 pm. If it is not helpful, then don't bother with it.
• DRINK LOTS OF WATER. The brain is about 80% water, and increasing your water intake to 7 to 10 glasses per day might be very helpful all by itself. Sodas, Gatorade, teas, icees, etc., do not count as water. Only water counts as water.
