THe US rda's are probably desgned to be close to what one gets with a good diet. The problem is that a good diet is not enough when people are mercury poisoned.

I found a very interesting article with uncommon facts/theories about mercury:http://www.advancedhealthplan.com/mercury.html

among the most interesting:

"Another person, attempting to smelt the silver in dental amalgams he obtained heated them in a frying pan. The mercury vapor thus generated killed him quickly. The two other family members in the house at the time also died." <img src="/ubbthreads/images/graemlins/shocked.gif" alt="" />

"The brain has a house-cleaning protein that removes dangerous waste products, which comes in three varieties: APO-E2, APO-E3, and APO-E4. The APO-E2 protein can carry 2 atoms of mercury out of the brain; APO-3, one; and AOP-E4, none. The genes we acquire from each parent determine which two we have. People with two APO-E4 proteins (and thus no APO-E2 or -E3) have an 80 percent chance of acquiring Alzheimer?s disease. And according to one study, autistic children have a huge preponderance of APO-E4 protein in their brains." <img src="/ubbthreads/images/graemlins/shocked.gif" alt="" />this is VERY interesting and could explain a lot

"The mercury in flu vaccines also plays a role in this disease. One investigator has found that people who received the flu vaccine each year for 3 to 5 years had a ten-fold greater chance of developing Alzheimer?s disease than people who had zero, 1, or 2 shots." this is not so shocking, we all really know that alzheimer and autism are caused by mercury.

"A small dose of mercury that kills 1 in 100 rats and a dose of aluminum that will kill 1 in 100 rats, when combined have a striking effect: all the rats die. Doses of mercury that have a 1 percent mortality will have a 100 percent mortality rate if some aluminum is there. Vaccines contain aluminum." <img src="/ubbthreads/images/graemlins/shocked.gif" alt="" /> this is crazy...
