Developing only in children, autism is a serious, lifelong neurodevelopmental disorder. One of the causes of autism is heavy metal exposure from baby food. However, in addition to causing autism, frequent exposure to toxic metals was also found to increase the severity of symptoms in children with the disorder.
By now, it is a known fact that exposure to cadmium, arsenic, lead, and mercury can contribute to the onset of autism in children, as these harmful metals act as neurotoxins. Neurotoxins directly target the brain and the nervous system and can negatively affect function in both developing and mature nervous tissue. However, children are extremely vulnerable to the effect of neurotoxin, as their brain and nervous system are still developing. Furthermore, neurotoxins can inhibit the ability of neurons to perform their usual intracellular functions or pass a signal to a neighboring cell. They can also induce systemic nervous system arrest or even nervous tissue death. All of these changes are strongly associated with autism.
Nevertheless, what few people know is that the higher the concentration of heavy metals in the body of a child with autism is, the more severe their symptoms will be, according to a study from the Journal of Toxicology. The study examined the relationship of autism symptoms in children with a heavy metal body burden and red blood cell glutathione levels, and the former was assessed by measuring urinary excretion of toxic metals. Researchers found numerous positive correlations between the severity of autism and the urinary excretion of heavy metals. Ultimately, the study demonstrates a considerable positive association between the severity of autism and the body burden of toxic metals.
In addition to discovering that children with a greater concentration of heavy metals in their bodies experienced more severe autism symptoms, the study from the Journal of Toxicology also found a striking similarity between the symptoms of children with autism and those with mercury poisoning. This is because the symptoms, which include mood changes, irritability, memory problems, lack of motor skills, feeling uncoordinated, and muscle weakness, overlap. The following are the most compelling findings of other studies on the subject:
Returning to the initial study from the Journal of Toxicology, the correlation assessment found multiple significant connections between the severity of autism and the urinary excretion of heavy metals. A higher body burden of toxic metals was linked to more severe autistic symptoms. The results of the analyses indicate that variations in the severity of autism might be partially explained by the toxic metal body burden. Nonetheless, the finding of a single relationship is not enough to establish causality.
A more recent study on the same subject - assessing the concentration of toxic metals in the hair samples of children with autism and correlating the level of these elements with the severity of autism - was published in the journal Maedica. The participants were 44 children between the ages of 3 and 9 with an autistic spectrum disorder. The severity of their autistic symptoms was measured by the Childhood Autism Rating Scale. These are the key findings of the research:
The results of the study were clear - the data supports the evidence that heavy metals play a role in the occurrence of autism and in combination with inadequate nutritional status. Inadequate nutritional status refers to feeding your infant or toddler toxic baby food or food with little to no nutritional value. The toxic consequences of these metals increase along with the severity of autistic symptoms. Lastly, the hair metal concentration was high for aluminum, cadmium, arsenic, mercury, antimony, nickel, and lead. 13 out of the 44 children showed values of vanadium above the reference range. None of the participants showed significant values for uranium and traces of chromium.
