If you read your thread again, here is a suggestion - try getting your hands on an issue of "Living Without" magazine, it is commonly sold at health food stores.
My daughter has real issues with both gluten and dairy, and at one point in her life, was awfully bitter about it, no matter what I said or did. One issue of this mag in her hands just to peruse at her leisure, and she felt much, much better. It is dedicated to folks, especially kids, with multiple food sensitivities/allergies/intolerances, and includes recent research, recipes, real-life social life trouble shooting, sources of ingredients, reworking recipes, personal stories of living with eating differently, you name it. Fabulous mag that we subscribe to.
I have a mantra that I have spouted for years... "If I eat right, I feel right. If I feel right, I exercise right. If I exercise right, I think right. If I think right, I eat right..." Phil-SC
