Limited Diet for High Functioning Autism

Autism is a complex neurological disorder that is characterized by communication difficulties, poor social development and repetitive patterns of behavior. Autism affects approximately three to six children out of 1,000. There is no cure for autism, but its symptoms can be managed with behavioral and educational interventions, therapy and medication. Many doctors and professionals in the autism community also believe that a diet free of gluten and casein can be used to manage the symptoms of autism.

Gluten-Free, Casein-Free Diet

Gluten is a generic term that is used to describe storage proteins that are found within grains. These proteins are known as zein in corn, oryzenin in rice, gliadin in wheat, avenin in oats, secalin in rye and hordein in barley. Gluten can also be found in artificial colors, flavorings, hydrolyzed vegetable proteins and food starches.

Casein is a protein that is found in milk and products that contain milk, such as yogurt, ice cream, whey, cheese, butter and certain margarines. Many non-milk products, such as hot dogs, may also contain casein, though it is in caseinate form.

It is thought that autistic individuals cannot properly digest gluten and casein. The undigested proteins form peptides, which are substances that act like opiates within the body. The presence of the peptides alter the individual's responses to the environment and general behavior and perceptions. According to AutismWeb, some scientists believe that the peptides can also adversely affect the immune system's response.

Following a gluten-free, casein-free diet, or GFCF diet, requires a lot of food modifications. Begin by removing milk and other dairy products, as the body will rid itself of the casein quickly. Follow up a month later by eliminating products that contain gluten. It can take up to six months of following a GFCF diet for your body to eliminate all traces of casein and gluten, so it's important that you stick to it and do not suddenly introduce foods that contain casein or gluten.

Precautions

Keep a journal that documents any behavioral improvements while following the GFCF diet.
Consider taking vitamin and calcium supplements to replace the nutrients that may be lost by following the GFCF diet.
Speak to your physician before you begin any type of diet.
