The GFCF Diet – ”The Autism Diet”

Previously, I mentioned that we had changed Aidan’s diet in the past few months. I came across the GFCF diet purely by accident and decided to give it a go. It is a struggle to find too many resources on the GFCF lifestyle other than a handful of websites. So, I decided to talk a little bit about it on the blog to help any other parents who may be thinking of giving it a try.

*I am not suggesting that you should put your child on a GFCF diet, I am simply talking about our decision and results. I obviously cannot guarantee any changes or results should you choose the GFCF diet.*

What is the GFCF Diet?

The GFCF diet is a diet whereby you eliminate all gluten and casein products from your diet. Casein is a protein found in dairy. Therefore, it is basically a gluten and dairy free diet.

Why does GFCF help people with autism?

The theory behind the diet is that people with autism have an underlying digestive issue. In recent years there have been more and more reports on a gut to brain relationship. This means that what you eat affects how your brain works. It is believed that in people with autism cannot break down the peptide bonds within gluten and casein to their simplest form. They can only break them down to a form with is similar to an opioid (like morphine or heroin) which intercepts the brain function. This would explain their random bouts of hysterical laughter, high pain tolerance, prolonged or irregular sleep patterns, and much more.

For it to work you need to stick to it 100%. Dairy will leave the system within 2-3 days but gluten can take up to 6 months to be completely gone so it is recommended to try the diet for at least 6 months.
