People often balk at the concept that a gluten-free diet may improve the condition of autistic children. For so many who have tried it, the proof is not in academic publications but in the (gluten free) pudding. Nothing is more compelling than seeing improvement with your own eyes, not even a randomized, double-blinded clinical trial.
Along the same lines as "vaccines can’t cause autism," dietary and environmental factors are often written off by conventional medical authorities in favor of a hitherto unavailable genetic explanation. They would much rather label something "idiopathic," a fancy word for "we don’t know," than to embark on a more extensive inquiry, such as exploring the causal factors embedded within everyday chemical exposures or dietary patterns.
But, the reality is that gluten contains a wide range of biologically active peptides, which the accumulating science on wheat toxicity now shows can profoundly affect neurological, endocrine, immune and digestive health, to name but a few body systems prominently affected. The incredulity of the conventional medical community towards the perspective that diet and behavior are intimately connected leaves many wondering how they attained such lofty positions of medical authority, or why we so readily give up our healthcare decision-making powers to them, in the first place.
This is, in fact, why I created GreenMedInfo.com. As an active aggregator and growing index of high-integrity, peer-reviewed and published biomedical research (entirely sourced from the National Library of Medicine), the information we provide the public enables them to access the first-hand science itself, removing the many-layered opacities and distortions of "expert opinion," which too often is compromised either with hidden agendas or outdated thinking, enabling our users to draw their own conclusions from the data itself.
So, let’s look at a study published in the journal of Nutritional Neuroscience in 2004 titled, "Immune response to dietary proteins, gliadin and cerebellar peptides in children with autism."
Researchers set out to illuminate the mechanisms behind the autoimmune reaction to nervous system antigens in autistic subjects. They took the blood of 50 autism patients and 50 healthy controls, and looked at the peptides from gliadin (a wheat protein) and the cerebellum, the part of the brain that plays a vital role in motor control, and cognitive functions such as attention, language and fear and pleasure responses.
The researchers found:
A significant percentage of autism patients showed elevations in antibodies against gliadin and cerebellar peptides simultaneously.
Then, the researchers used an animal model to find out whether these simultaneous elevations were a result of cross-reactivity between dietary proteins and cerebellar proteins (antigens), i.e., whether the immune system produces anti-gliadin antibodies which mistakenly attack brain proteins.
They found rabbit anti-gliadin and anti-cerebellar peptides cross-reacted by greater than 60%, spurning them to conclude the following:
We conclude that a subgroup of patients with autism produce antibodies against Purkinje cells [a GABA-producing neuron from the cerebral cortex] and gliadin peptides, which may be responsible for some of the neurological symptoms in autism.
