Special diets free of artificial colors/flavors, etc

Has anyone found it helpful to take out artificial flavors, artificial colors from a child's diet?  Let me know about your successes. I was watching a video about the Feingold diet.

Hi, my son has adhd and odd amongst other things. I put him on an e-free diet from the age of 2yrs, it does help a little but i think it helps really because it's more healthy. Because of his meds though I had to relax this but still don't give him fizzy drinks or sweets he has cakes though as a treat for being listening and generaly being good but limit this to 'end of the week treat. I have not heard about the diet you mention though.
Good luck.
