Can your school do this???

Yesterday our son decided to try the school lunches in his new school. The menu appears to have healthy options. However, I don't like to take chances because eating or drinking foods with the artificial colors would mean drastically altering my son's behavior from good to dye-induced ugliness. Therefore, our son has a doctor's note explaining that he is not to have any artificial food colors in his food or drink beverage. I was then given the lunch menu for each day of the week and instructed to circle which foods he would like to eat. Next, I would be given the ingredients for each item for my son's doctor to look over. The food dietitian would then make an alternative if needed for each item that our son is not allowed to eat. As more and more people are becoming aware of harmful dyes and food additives, some schools are choosing healthier options. If the word gets out that I was allowed to do this then others might follow suit. It might just be easier to make foods this way to begin with. Don't we all want our children to eat real foods instead of foods that look real?
There is a school in San Juan Island School District that has chosen to stay away from artificial dyes and preservatives. The link is below:
