Living in Grand Rapids, MI, one of the call to fame of this city is that it proudly touts itself as the "First City in the World to Flouridate its Drinking Water." The idea was that it would help with kids teeth and prevent cavities.
There exists a second camp that thinks Flouridated water is bad for you. That fluoride will accumulate in the Pineal gland. It will calcify and prevent the pineal gland from producing melatonin. Melatonin is important for sleep and potentially other health benefits.
Both of these statements seem to be true. The website Flouridealert.org, contains pros and cons and in fact I found the most information about the pros and cons from them. Pineal Gland. It also shows research that perhaps fluoridated water speeds up puberty for girls.
This article from them states that fluoride is great and it's like getting vitamin fortified food. Flouridation: Science over Propoganda.
This video I found of bodybuilding legend Dorian Yates talking about his refusal to drink the tap water. The importance of the Pineal Gland and it's other implications as a spiritual "third eye."
Where do you stand on fluoridated water? I think I fall on more of the I'll skip the water and drink filtered water. I'm not comfortable for people making health choices for me. The difference being I have a choice if I want fortified food. The risk of a cavity to me seems small compared to risking the health of your pineal gland.
Perhaps I'm just falling for the propaganda. I do love conspiracy theories.
