The Gluten and Casein Free diet theory understands that people with Autistic Spectrum Disorders (ASD) or associated conditions will show some improvement on such a diet. One Australian study found that necessary gut bacteria (enterococci faeceum) are not present in children with ASD, while another study from the Autism Research Unit at the University of Sunderland explains in the ‘Opiod Excess Theory’ that there is incomplete breakdown of Gluten and Casein releases peptides which as a result of a ‘leaky gut’ gets absorbed and crosses the blood-brain barrier into the central nervous system (CNS). This causes disruption of the normal CNS processes affecting cognition, perception, emotions, mood and behaviour. In children with ASD and other associated conditions the gluten and casein is toxic to their systems. This is not an allergy and therefore allergy tests will not show anything. Indeed, only a proportion of children will show a positive change and therefore not everyone may find it of benefit.
Gluten can be found in bread, pasta, cereals, flour, pizza bases, cakes and biscuits. It can also be an ingredient in soups, sauces, ready meals and processed foods. Casein is a protein found in milk. Milk is used to many commercial products and therefore reading food labels carefully to check for ingredient is important. Avoid anything that contains milk, skimmed milk, condensed milk, milk solids, casein, whey, whey solids, lactose and caseinate.
