Autism, ADHD, and how my family's diet evolved

My family became gluten-free a few years ago in efforts to try to ease the symptoms of my son's autism. Despite being gluten-free, we still had great difficulty with his sleep and continence issues until recently. Recently, we switched to a dye-free diet. After a couple of days dye-free, my son was able to sleep through the night and begin gaining control over his bladder. The effects of the dietary change were so profound and important to our family that I decided to make the whole house into a dye-free zone, including soaps and cleaning products.
After a couple of weeks I realized that my son was also effected by preservatives and pesticides, so we went all organic. Additionally, I realized he experienced gastrointestinal problems from corn and rice. With all these restrictions I had to learn how to cook in a way that would both satisfy and nourish a six year old boy while staying in budget. Hence, organic, grain-free, soy-free vegan recipes evolved.
