Dangerous Levels Fluoride
Fluoride found in toothpaste, fluoridated water, and non-organic food have proven to be very dangerous for humans. Conventionally grown iceberg lettuce can contain as much as 180 ppm of fluoride, which is 180 times higher than the levels found in household pipe water.
According to many scientists, fluoride leads to damage of the brain, dental fluorosis, weaken bones and many other health issues.
