An article from keepmecurrent.com reveals a study from Norway that connects an enzyme deficiency with hyperactivity in children.
In the trial, 23 children with hyperactivity disorders were given milk- and/or gluten-free diets.
It takes a certain enzyme to break down proteins, such as casein, found in dairy products and foods that contain gluten. Children with conditions such as attention deficit hyperactivity disorder (ADHD) are believed to lack that enzyme, and therefore the restricted diet was intended to provide symptom relief.
In fact, in the Norwegian study, 22 of the children had improved symptoms, including positive behavioral changes, enhanced attention and better learning abilities. When the suspect foods were reintroduced, symptoms returned.
Autism and schizophrenia also have been linked to casein and gluten digestive disorders.
