In Baby Teeth, Links Between Chemical Exposure in Pregnancy and Autism

Copper zincThis headline in the New York Times seems to indicate that chemical exposure during pregnancy can lead to autism. There are myriad chemicals going into Moms to Be these days - a far cry from when I had my girls and was not allowed even a cup of coffee, let alone anti-depressants and aluminum and mercury laden vaccinations. And yet, look below at the paragraph that veers sharply away from "external exposure" (code! code! code! code!) as the headline would imply.  Also note the sentence that tells Moms this is not about anything "she did." I don't see this as a move away from refrigerator theory so much as a way to convince Mom her intake of chemicals had nothing to do with her child's autism. Share your thoughts.

In Baby Teeth, Links Between Chemical Exposure in Pregnancy and Autism

If you are a parent worrying through pregnancy, or maybe trying to make sense of your child’s neurodevelopmental problems, you aren’t always glad to see another story about a new study looking at possible environmental risk factors. From pesticides in the food to phthalates in the plastics to pollutant particles in the air, so many different exposures have been linked to problems in the developing fetal brain that parents can sometimes feel both bewildered and, inevitably, at fault for failing or having failed to take all possible precautions.

That’s a great pity, because the accumulating research is of tremendous value, particularly to families struggling with an autism diagnosis. But there’s an unfortunate tendency to treat each new study as a single explanatory solution to what is in fact a tremendously complicated and multifactorial issue.

....The record in teeth may show associations with autism but does not mean that the mother did something to cause the condition, experts say.

....Curtin, an assistant professor of environmental medicine and public health at Mount Sinai who was first author on the study, said that in children with autism, regulation of zinc and copper metabolism shows differences beginning early in the course of fetal development. The point of the study was not to look at whether a child had been externally exposed to these metals, but rather at the internal metabolic rhythms of nutrients and possible toxins, at “what are the dynamics of zinc and copper metabolism, and how are those dysregulated in disease.”

I did a cursory search for mercury and zinc/copper and found a study from 2009  linking learning disabilities with low nutrient levels in conjunction with environmental mercury.   Mercury exposure, nutritional deficiencies and metabolic disruptions may affect learning in children

There is evidence to suggest that the body's ability to maintain neuronal plasticity when essential dietary nutrients are lacking can be additionally impaired by exposure to environmental mercury. This article provides a review of such evidence and a model of how this toxic effect of mercury may occur (Figure (Figure11).

This reminds me of hair analysis - looking for “internal metabolic rhythms of nutrients.” Most of the NYT comments are really clueless, unfortunately.

I just don't get it ! mercury Toxicity Model ? Whatever are you talking about ?

The British Dental Association put mercury in all our teeth growing up.
And in fact they still do - to the working classes ONLY mind (to maintain the status quo ?).
And the BDA (as do the ADA) still defend the practice, a full two thousand years after the Roman Senate discussed whether it was ethical or not to send slaves to work in the mercury mines of Italy & Spain (criminals were routinuely sent to them, and to their deaths ! but slaves were not criminals - so the question for the politicians of the day was - was it right to send slaves to their deaths ?)

According to the article: "Curtin, an assistant professor of environmental medicine and public health at Mount Sinai who was first author on the study, said that in children with autism, regulation of zinc and copper metabolism shows differences beginning early in the course of fetal development. The point of the study was not to look at whether a child had been externally exposed to these metals, but rather at the internal metabolic rhythms of nutrients and possible toxins, at “what are the dynamics of zinc and copper metabolism, and how are those dysregulated in disease.”

One can only wonder if these dedicated "environmental scientists" have ever heard of Italian scientists Stefano Montanari and his wife Antonietta Gatti's courageous pursuit of toxic vaccine ingredients they found:

"16 years ago, using an electron-microscopy method based on two European research projects, we began to analyze vaccines and, to date, we have examined 35 different types of those drugs, 10 of which are now mandatory in Italy. The results are well-known: all the samples were found to be polluted by micro- and nanoparticles, none of them compatible with the human organism."

Admittedly .. I am NOT a scientist .. but .. common sense suggests the greater danger of exposing the early developing fetus to "internal metabolic rhythms of nutrients and possible toxins" would occur when the fetus is exposed to the toxins by "injection" .. which deliberately evades the fetus natural defenses against such toxic exposures .. thereby making the minute "micro- and nanoparticles" even more dangerous.

But .. that's just silly old me.
