Re: Green Tea, Fluoride & the Thyroi

[Guest guest]

I have a question...

Since flouride can substitute for iodine... If tea is grown in iodine rich

soil that doesn't have much flouride - can it have as much iodine as

conventional tea has flouride? (.8 mg per 8 oz cup)

Thanks!

Lana, according to this article, fluoride in plant leaves comes mainly

from the air. I'm not sure if that is true for tea as well.

http://www.greenfacts.org/en/fluoride/fluorides-3/02-environment.htm

================================================================

Most of the fluoride in the soil is insoluble and, therefore, less

available to plants. However, high soil fluoride concentrations or low

pH, clay and/or organic matter can increase fluoride levels in soil

solution, increasing uptake via the plant root. If fluoride is taken

up through the root, its concentrations are often higher in the root

than in the shoot, due to the low mobility of fluoride in the plant.

Most fluorides enter plant tissues as gases through the stomata and

accumulate in leaves. Small amounts of airborne particulate fluoride

can enter the plant through the epidermis and cuticle. Vegetation has

been widely monitored in the vicinity of anthropogenic fluoride

emission sources. Correlations between fluoride concentrations in

vegetation and annual growth increments, wind pattern, distance from

fluoride source and hydrogen fluoride concentrations in aerial

emissions have been observed.

Here's the full article:

I'm also not sure this information is correct, since the article was

funded by governments and the " Green Facts " organization was founded

by the Solvay Group and appears to be funded largely by industry and

government.

However, it would be great to find a way to produce tea and kombucha

with iodine instead of fluoride

Apparently fluoride in tea leaves does come mainly from the soil and

is enhanced by aluminum in the soil: " Uptake of fluoride by tea plant

(Camellia sinensis L) and the impact of aluminium "
