One thing I have learnt is when you see something being promoted by the nutter, Dr Eric Mercola, you know its nonsense and pseudoscience. He promotes snake oil and quackery. he misquotes and misinterprets research; he lies about research to suit his agenda. Others do that, but he has to be the worst.
His latest pile of sh*t is this one in the Huff post on fluoridation. He leads off with a study that shows how fluoride affects IQ of kids. What is fails to say is that it was mega does of fluoride that affect IQ, not the miniscule amounts that are in our drinking water. Many people in the comments section point that out. Notice how the fan boys are so blind to what they are being told.
