I've recently seen a quote by one William Douglass, MD, making the rounds on facebook. It sounded suspicious, so I found the original quote on his own website:
People who warned against FLUORIDATION used to be ridiculed, but guess what? In Scandinavia, in fact all of Europe, and nearly every other medically advanced nation, they have now banned the practice.
Know why? Because fluoride makes your body absorb extra aluminum . And where does the aluminum go? Your brain. And what metal shows up alarmingly in the brains of Alzheimer’s victims? You guessed it. (Hmm Maybe our health authorities have been drinking too much water?)
The first part of the quote is clearly false, which is perhaps why that part was omitted from the recent meme, which appears as:
Fluoride makes your body absorb extra aluminum . And where does the aluminum go? Your brain. And what metal shows up alarmingly in the brains of Alzheimer’s victims? You guessed it.
I'm skeptical about fluoride's role in "making" your body absorb extra aluminum. Presumably this means that it somehow makes your body more efficient at absorbing aluminum, or less efficient in eliminating aluminum, because that "extra aluminum" must come from somewhere. Is there any research to support this claim?
