David Kirby on HuffPo: Rain, Autism and Mercury

Acid_rain2Managing Editor's Note:  Editor at Large Mark Blaxill wrote an Age of Autism post called Mercury is in the Air last spring.

Click HERE to read David Kirby's latest piece at Huffington Post on the Cornell study linking rain and autism. Click here (MERCURY MAPS) to see graphics on mercury in the air. In th HuffPo piece David says:

A new study out of Cornell University says that children growing up in the rainiest or snowiest areas of the country seem to have a higher risk for autism than children living in drier climates.

The authors estimated that removing precipitation as a factor in autism would slice the prevalence of the disorder by 33% to 43%.

Among the possible explanations given were: A lack of vitamin D from a sun-deprived life under the clouds, an increased amount of time spent indoors amid toxic household chemicals, or the presence of dangerous neurotoxins in the precipitation itself, which in turn might trigger a genetic predisposition to ASD.

One of the most omnipresent, growing (and obvious) air-borne neurotoxins in the world to consider, of course, is mercury...

Please read these findings I have researched on the internet, I find them pertinent to our famil, in that I have MS and two children with autism, which are VIT D deficiency diseases. (and toxins, and viruses and fungi, but that's another email). Both on our genomic snps and testing of VIT D to be extremely low, and we live in Oregon, one of the c ountries most rainiest states, or grey if you will, with a rate of autism very high at 1-98. I also believe the common component of low selenium in soils creates a hyper condition for viruses to "mutate". In the presence of humans who ingest low selenium value foods you find HIGH LEVELS of AIDS, CANCERS, MS, and the like. I also found out today that Cystic Fibrosis kids also have very low VIT D. They have also low GLUTATHIONE. Interesting? So here is what I gathered below...

Check these on genomic snps, they are most likely OFF in autism

VDR polymorphisms are simply the different structures of the vitamin D receptor that different people have and they are widely distributed. A highly significant association exists between one VDR polymorphism and larger head size. Mean head circumference is larger in autism.

The first thing to do is stop all vitamin A, multivitamins containing vitamin A, or cod liver oil and start vitamin D. Vitamin A antagonizes the action of vitamin D. I think the easiest way to give vitamin D is powdered capsules, not a cream. You can open the capsule and put the powder in about anything, such as juice.

Vitamin A antagonizes the action of vitamin D. In humans, even the vitamin A in a single serving of liver impairs vitamin D's rapid intestinal calcium response. Furthermore, the consumption of preformed retinols, even in amounts consumed by many Americans in both multivitamins and cod liver oil appears to be causing low-grade, but widespread, bone toxicity, perhaps through its antagonism of vitamin D. In a recent dietary intake study, Kyungwon et al found high retinol intake completely thwarted vitamin D's otherwise protective effect on distal colorectal adenoma (6) and they found a clear relationship between vitamin D and vitamin A intakes as the women in the highest quintile of vitamin D intake also ingested almost 10,000 IU of retinols/day. As early as 1933, Hess et al warned about vitamin A consumption, concluding, "as to a requirement of thousands of units of vitamin A daily, the unquestionable answer is that this constitutes therapeutic absurdity, which, happily, will prove to be only a passing fad."

Hess AF, Lewis JM, Barenberg LH. Does our dietary require vitamin A supplement? JAMA. 1933;101:657-663.

Unfortunately, Hess's prophecy of a passing fad proved premature and many Americans continue to consume "absurd" and dangerous quantities of vitamin A. For example, multivitamins, until recently, had small amounts of vitamin D (200 to 400 IU) but high amounts of preformed retinols (5,000 to 10,000 IU). This pales in comparison to a tablespoon of modern cod liver oil, which contains sub-physiological amounts of vitamin D (400 to 1200 IU) but supra-physiological amounts of completely preformed retinols (5,000 to 15,000 IU or in some cases 30,000 IU).

Abnormal immune responses are associated with both autism and vitamin D deficiency. For example, autistic individuals have immune abnormalities that show a striking similarity to the immune functions affected by vitamin D. Animal evidence indicates some vitamin D deficiency induced brain damage may be malleable, that is, vitamin D may partially reverse the brain damage, if given early enough. These studies offer hope that sunlight or oral vitamin D, especially in young autistic children, may have a treatment effect.

Both the brain and the blood of autistic individuals show evidence of ongoing chronic inflammation and oxidative stress. That is, the disease process is probably increasingly destructive. Further hope for a treatment effect rests in activated vitamin D's powerful anti-inflammatory properties. Its administration reduces production of inflammatory cytokines in the brain, which have consistently been associated with cognitive impairment. Furthermore, activated vitamin D is remarkably neuroprotective by stimulating neurotropin release, reducing toxic cellular calcium levels in the brain, inhibiting the production of nitrous oxide, and by its immunomodulating properties, especially in reducing inflammatory cytokines and by increasing brain glutathione.

This last function of vitamin D, increasing cellular levels of glutathione, may explain the purported link between heavy metals, oxidative stress, and autism. For example, activated vitamin D reduces iron-induced and zinc-induced oxidative injuries in rat brain. The primary route for the neurotoxicity of most heavy metals is through depletion of glutathione and subsequent generation of reactive oxygen and nitrogen species. Besides its function as a master antioxidant, glutathione acts as a chelating (binding) agent to remove heavy metals. Several studies indicate autistic individuals have difficulty excreting heavy metals, especially mercury. If vitamin D deficient brains are unable to utilize glutathione properly, and thus unable to remove heavy metals, they may be oxidatively damaged by heavy metal loads normal children easily excrete. The amount of activated vitamin D in the brain directly depends on how much vitamin D is made in the skin or put in the mouth.

It is too early to say vitamin D has a treatment effect in autism. However, a simple risk/benefit analysis suggests that autistic children should be diagnosed and aggressively treated for vitamin D deficiency.

You can read a similar document for free on the website, where we first published the theory a year ago.

In summation, autistic children should be given enough vitamin D to get their 25(OH)D levels up to the mid to high range of normals, that is, 70 ng/ml (175 nmol/L in countries that use the metric system). In the absence of sun exposure, this usually requires long-term administration of about 1,000 IU/day per 20 pounds of body weight with a loading dose of 2,000 IU of vitamin D/day for every 20 pounds of body weight for the first two weeks. As individual variation in response is very high, they should have 25(OH)D blood tests every month until their level has stabilized around 70 ng/ml. They should stop all products containing preformed retinols (vitamin A), including cod liver oil.

study after study connects mercury with an increase in ASD when will the mainstream stop lying and attempting to decieve the public? In case they havent heard the public is not eating the excrement sandwiches the so called mainstream medical community is dishing out. Now we also have Tayloe jr heading the AAP. This man publically stated he had never seen or personally heard of a child having an adverse reaction to vaccine. Never in his practice. Too bad the interviewer didnt ask him about his fathers practice. Tayloes father had been sued for giving a child a vaccine the child had already had a bad reaction to frying the childs brain. Tayloe will likely direct the AAP to continue ignoring the science,and to continue to dish out excrement sandwiches.

This is more important than it may seem at first. My son, had a mold exposure to penicillin aspergillus at 5 and ended up with developmental regression, an eye condition frequently seen in spectrum kids and a few autistic traits. Two years later, after treatment with chinese herbs his neurotransmitters are normal and his digestion has normalized. I also had the exposure and could not remember our phone number and had a loss of executive function. It has taken a while for us to recover and he is not vaccinated. Mercury can disrupt the flora. Many parents do not realize how damaging mycotoxins can be.

Since Katrina, there have been many cases of kids regressing and then recovering after being treated for mold.

It is so frustrating that researchers fail to connect the dots and ask "Why?".
This, I thought, was the cornerstone to good research.
When investigating children with a 40% rate of mitochondria disorder, heavy metal toxicity from vaccines, with fractured immune systems, it doesn't take a Harvard PhD to figure our why lack of sun light and excessive pollution decreases their break strength.
The question is how did this happen inside a couple decades?
Surely, rain, pollution, older parents have been around for centuries.
No known outbreaks of 1:150 during the industrial revolution.
Blame it on the rain?
No, how about finding what makes a normal child so sick even rain becomes a toxin.
