I started Missy on the Feingold diet. It made a big difference. Gradually, as the diet states, I began introducing things back into her diet. I found that her biggest triggers are corn syrup (chemically altered corn starch) and food coloring. (To be quite honest, I think those things trigger easy child's too. It does with mine, but just not to the extremes and he just gets a bit hyper. I've never had raging with him.) I have even found out that too much of natural food colorants can cause problems and even the products that are found in "organic" gum.
Feingold is going to be tough on a 10 year old. I started Missy when she was four and it wasn't so bad. She knows what she's not supposed to have now, even though she does sneak things in once in a while. I can always tell, because she either rages, gets extremely moody or gets extremely emotional.
You can check out feingold.com and it explains the diet in more detail.
