"I could tell something was wrong with him as soon as he began eating solids as a baby. It was if the food was draining him," says Rita, 50, describing how her son Christoffer had yoyoed between passive and hyperactive behaviour until she had removed several staples from his diet including milk and grains.
Christoffer, today a normally developed 14-year-old, is one of 23 children suffering from hyperactive disorders who were put on milk-free diets in 1996-1997 and whose development has been tracked ever since by a small group of educators and researchers in the southwestern Norwegian town of Stavanger.
The group set out to prove a theory by Oslo-based scientist Karl Ludvig Reichelt that a metabolic disorder making it difficult to break down certain proteins, including casein (the protein in milk that makes it possible to make cheese), could cause mental problems like Attention Deficit Hyperactivity Disorder (ADHD).

"It's incredible. We've seen intelligence tests that had gone steadily down suddenly turn around and go back up" after a change of diet, says Ann-Mari Knivsberg, who covers the research end of the Stavanger project.
