Re: Green Tea, Fluoride, and the Thyroid
You are overlooking one very important point. Dosage makes the poison. Fluoride does play an essential role in the body, but in excess it can create problems. Just like too much calcium can cause problems. And too much oxygen can kill people.
But the most interesting point of your post was this one sentence:
"Dental fluorosis (mottled teeth) is the first visible sign of fluoride poisoning."
So why are we not seeing massive outbreaks of fluorosis in the US, China, and England especially considering the popularity of teas in these countries? Keep in mind that this would be in addition to the man other sources of fluoride we are exposed to on a daily basis. For example, the water we drink, toothpastes and dental rinses, and refined foods and juices that use concentrated fluoride from the water sources they use.
By the way, I have relatives that live in a small town North of here where the naturally occurring fluoride in the soil has created fluorosis in all of the town's people. Yet they are not suffering from brain damage or an increased risk of cancer, compared to the rest of the country. There are apparently a lot of facts you are overlooking. Like did you know that the treatment for fluoride poisoning is calcium? So calcium intake is one factor. And there are different forms of fluoride. Just like not all chromiums are the same. Trivalent chromium is beneficial to the body as where hexavalent chromium is quite toxic. The fluoride added to drinking water, toothpaste, etc. is a toxic waste product of the aluminum and fertilizer industries. And in my state it is classified as a schedule A poison, which makes it illegal to add to the water supply, even though they added it anyway. Naturally occurring fluoride is not necessarily the same, but as I pointed out it can still be problematic if in high enough concentrations.

Pay attention to the levels of fluoride in lettuce.
Seafoods are also a rich source of fluoride, but again there are other things in these foods that can counter the effects of the fluoride such as
Iodine and calcium. In short you are only telling a small fraction of the whole story and leaving out the important facts that counter your claims.
