Many theories about avoiding Alzheimer's are debunked by government released information. Avoiding Alzheimer's disease turns out to be a relatively simple task.
Fluoride poisoning?
Several scientific studies show that fluoride has adverse effects on the brain. It has been implicated as a cause of memory lapses, dementia, ADHD and autism. It is said to reduce IQ and has been named a cause of Altzheimer's Disease. It is linked not only to hypothyroidism, but also to hyperthyroidism, osteoporosis, skeletal fluorosis, kidney disease, and cancer.
It causes a condition of the teeth called dental fluorosis. Although fluoride proponents claim fluoride protects teeth from tooth decay, it actually damages them. In western Europe where fluoridated water was rejected, children's dental health is just as good as here in the USA.
Perhaps the most interesting side effect, it is said that fluoride affects a section of the brain that regulates our reactions to stressful circumstances, making human beings easier to control. This results in a docile population that might otherwise fight against injustice and oppression.
