Quote From: larisa67My son's behavior changes drastically when he eats artificial additives (colors, flavors or preservatives). He is on the Feingold Program which eliminates all these things. We have had great success as long as I have complete control. When he goes to school, I won't and I don't want to home school. I don't know what to do. Most school lunch programs are loaded with junk and additives. I guess I could start now and try to urge them to make changes. It would benefit the behavior and learning of all children to take this stuff out of their diet, at least at school. Many, Many studies show that these additives cause learning & behavior problems. You would think schools would know this and do something about it. Maybe I can make them change. We'll see! 
I don't know how your public school's lunch program works but ours is not mandatory. In other words, you pack the foods that you want your child to eat. The school lunch here is semi healthy, they serve veggies and fruits, but I bet most kids don't eat them. At least when I pack the lunch I know what she is eating.
While the Feingold Program may work for your son, it made no difference with my daughter's ADD. We limit "junk" food in our home anyway and it is considered a treat and not the norm. My daughter's issue is focus and not behavior. Don't know if the program has more effect on hyperactivity or not.
It will an uphill battle trying to change the school district. Most programs are budget driven and major changes can prove costly to the schools. Best way to make any changes is with a group of like minded parents. If one person complains, they are a pain in the neck, if a group complains, they are more likely to be listened to. Good luck if you do try to change the schools and in the meantime I suggest a good lunchbox!!
