Remember the lady last time who wanted to provide her doctor husband with convincing, scientific evidence that food intolerances really can affect their children's health?
One reader suggests he reads The Nutrition Solution by H. Kristal, or Breaking The Vicious Cycle by Elaine Gottshall. Another suggests that our questioner undertake a six-week trial of removing foods from her children's diet. Start by taking all dairy out of the diet for at least six weeks, then remove wheat for the same amount of time. Then tell him to monitor the results.
