Food Allergies–a correlation has been found between the number of allergies hyperactive children had and their teachers’ ratings of hyperactivity. Approximately one out of every two hyperactive children seemed particularly sensitive to plant and animal proteins such as oats, rye, beef, chicken, and eggs. However, for most of these children, taking the allergy-producing foods out of their diets had no greater effect than simply placing them on a new diet, unrelated to their allergies.
Dr. Doris Rapp, on the other hand, obtained some promising results in giving hyperactive children food allergy extracts. She devised this approach because many parents had difficulty following through on diet restrictions for their children. You can read further on her food allergy treatment in The Impossible Child, by Doris Rapp and Dorothy Bamberg, 1986.
