Neurotoxins, Brain Development, and Toxicity (Study adds six new known agents, including fluoride)

marblesShould you care about toxins that might affect your child’s development and brain in particular? Aren’t these everywhere and thus it’s pointless to worry? If your child was exposed, or mom was exposed during pregnancy, isn’t it just too late?  Yes, please do care. You should be concerned because it’s important to identify exposures that you can avoid. It’s never too late! I use the example of a tin can (represents our bodies) and marbles (representing toxins entering our body).  We are constantly adding marbles from conception and the time in the womb to the day we leave the earth. Other than eating right and getting all the nutrients we need, along with adequate sleep, exercise, and avoiding stress and toxic or dangerous situations; minimizing toxins is THE MOST IMPORTANT ACTIVITY we can do for long term health and well-being. The fewer marbles (toxins) we put in our bucket (body) the better.  The other important aspect, see other blogs on this, is to enhance detoxification so you can eliminate the toxins (marbles) faster.  Have you noticed there is more and more dementia and Alzheimer’s these days?  You might wonder if toxins early in life affect the brains of developing children in a certain way and the lifetime accumulation leads to a different presentation of lost brain function? 


Pregnant moms and moms-to-be, your womb is the whole world for your developing baby. Avoid stress as much as possible.  Families should rally to help keep this a precious time of love and healthy living. Get help if you can’t stop drinking or taking substances that might harm your baby. Double check that any medications you might be taking are ok. Eat organic and, please, absolutely no aspartame (diet drinks, diet food and most gum). I am horrified that the new recommendation in the USA is to give every pregnant mom a Tdap to boost mom’s antibodies against pertussis so babies are born with extra protection.  That is all true and wonderful except that the vaccine has 170-330 or more micrograms of aluminum, which is a known neurotoxin.  Premature babies cannot get more that 10-15 micrograms a day (FDA rules for TPN – Total Parenteral Nutrition), so clearly 170-330 micrograms is a huge toxic dose at a time the brain is just developing. 


After birth, this first year or two of life is most critical for your child’s health and the development of a good immune system. The current vaccine schedule in the USA has 21 vaccines in the first year of life.  This is a huge stimulation of the immune system that artificially shifts it toward allergies, but it also is exposing the developing brain to huge doses of aluminum.  (See other blogs on this topic). I am in favor of individualized vaccine schedules that make sense for your family risk factors, genetics, and situation. 


A systematic review of neurotoxins in 2006 outlined the dangers of lead, methyl mercury, polychlorinated biphenyls, arsenic, and toluene. The current paper by Granjean and Landrigan (you can read it here… ) adds  six additional developmental neurotoxicants—manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachloroethylene, and the polybrominated diphenyl ethers . 


Since that time, the journal Environmental Health Perspectives has published papers outlining 10 top toxins for neurodevelopment listed here:


  1. Lead (Jusko et al. 2008)
  2. Methylmercury (Oken et al. 2008)
  3. Polychlorinated biphenyls (Winneke 2011)
  4. Organophosphate pesticides (Eskenazi et al. 2007London et al. 2012)
  5. Organochlorine pesticides (Eskenazi et al. 2008)
  6. Endocrine disruptors (Braun et al. 2011Miodovnik et al. 2011)
  7. Automotive exhaust (Volk et al. 2011)
  8. Polycyclic aromatic hydrocarbons (Perera et al. 2009)
  9. Brominated flame retardants (Herbstman et al. 2010)
  10. Perfluorinated compounds (Stein and Savitz 2011).

With thousands of untested chemicals in use already and more being added every year, what can you possibly do?  Notice fluoride!  Most pediatricians and family doctors and dentists are still recommending that you give extra fluoride to your children to protect their teeth. With the known neurotoxicity and the fact that fluoride competes with iodine for the thyroid receptors, it just doesn’t make sense anymore to intentionally take extra fluoride. The endocrine disrupters are either pesticides, herbicides, or chemicals of the petroleum industry and plastics, so these can be minimized by avoiding plastics and avoid applying petroleum products to your skin, drinking only charcoal filtered or reverse osmosis processed water.  Eating organic becomes increasingly an important health strategy.
