Last year, four scientists announced that some autistic children were found to have a zinc deficiency.
Scientist Hiroshi Yasuda and colleagues published this discovery in the study, Infantile Zinc Deficiency: Association with Autism Spectrum Disorders.
According to Yasuda and co-authors, they compiled the information by testing hair samples from 1,967 children who had autistic disorders, which impair the ability to communicate and socialize.
“In particular, nearly one half (male: 43.5 %; female: 52.5 %) of the autistic infants aged 0–3 [years old] were found to suffer from marginal to severe zinc deficiency…,” the scientists noted in the published research.
Why is zinc so important? As the Linus Pauling Institute has noted, this mineral is involved in nerve impulse transmission.2 And scientists have found that patients with autism have abnormalities that inhibit the ability of brain cells to transmit nerve impulses properly.3
There are also indications that a zinc deficiency can lead to a build-up of toxic metals. The autism study from Yasuda and colleagues stated that “patients with zinc deficiency have a low excretion ability of toxic metals and [this results] in a higher body burden with them.”
