In the previous article, I discussed mercury amalgam fillings and anti-D injections as possible causes of autism. Now I will discuss the pregnant mother’s diet and the diet of her child.
Some research, from 1997 has suggested that if a mother-to-be eats fish during her pregnancy, it may cause developmental disabilities in her child. (2)
In the Faroe Islands, the main part of people’s diet is fish, so researchers looked at more than one thousand children born there between 1987-1988. In a study published in 2006, researchers examined cord blood, tissue and samples of the mother’s hair to determine how much mercury infants were exposed to in the womb.
Neuro-behaviorial tests were performed when the child reached seven years of age and again at 14 years of age. They determined that although the cognitive function of the children had not worsened between seven and 14 years (indicating their own fish consumption hadn’t harmed them), there were deficits noticed in infancy, meaning that the risk of neurodevelopmental disorders resulted from pre-natal exposure to mercury in fish.
“Indicators of prenatal methylmercury exposure were significantly associated with deficits in finger tapping speed, reaction time on a continued performance task, and cued naming ... The effects on brain function associated with prenatal methylmercury exposure therefore appear to be multi-focal and permanent.” (1)
In 2005, Environmental Health Perspectives found in their analysis of various studies into mercury and fish consumption, that "These results support findings from some studies that higher mercury exposure in pregnancy is associated with lower offspring cognitive scores, even at these relatively low levels of exposure.” (3)
The risk increases with the amount of mercury in the fish. Because of this, women have been advised to continue eating fish during pregnancy, but to choose varieties that are lower in mercury.
Some medical professionals contend that malnutrition is an underlying cause of autism.
