Re: flouride in green tea

[Guest guest]

Shari,

Somewhere back in the message archives, I believe we discussed green tea... I've heard mostly good as i recall. To date, the only negative side effect reported from drinking green tea is insomnia due to the fact that it contains caffeine. However, green tea contains less caffeine than coffee: there are approximately thirty to sixty mg. of caffeine in six - eight ounces of tea, compared to over one-hundred mg. in eight ounces of coffee.

here is another article.

Anti-cancer function of green tea explained

2005-03-15

Researchers at the University of Murcia in Spain (UMU) and the Innes Center (JIC) in Norwich, England, report that EGCG (epigallocatechin-3-gallate) prevents cancer cells from growing by binding to a specific enzyme. "We have shown for the first time that EGCG, which is present in green tea at relatively high concentrations, inhibits the enzyme dihydrofolate reductase (DHFR), which is a recognized, established target for anti-cancer drugs," Professor Thorneley, of JIC, told Reuters. "This is the first time, to our knowledge, a known target for an anti-cancer drug has been identified as being inhibited by EGCG," he added. Green tea has about five times as much EGCG as regular tea, studies have shown. It decreases rates of certain cancers, but scientists were not sure what compounds were involved or how they worked. Nor had they determined

how much green tea a person would have to drink to have a beneficial effect, he said. "We have identified this enzyme in tumour cells that EGCG targets and understand how it stops this enzyme from making DNA. This means we may be able to develop new anti-cancer drugs based on the structure of the EGCG molecule," Thorneley explained. The scientists noted that the structure of ECGC is similar to a cancer drug called methotrexate. "We discovered that EGCG can kill cancer cells in the same way as methotrexate," Dr Neptuno -, of UMU, a joint author of the research published in the journal Cancer Research. EGCG binds strongly to DHFR, which is essential in both healthy and cancerous cells. But it does not bind as tightly as methotrexate, so its side effects on healthy cells could be less severe than those of the drug. EGCG is probably just one of a number of anti-cancer mechanisms in green tea, Thorneley added. The findings could

also explain why women who drink large amounts of green tea around the time they conceive and early in their pregnancy may have an increased risk of having a child with spina bifida or other neural tube disorders. Women are advised to take supplements of folic acid because it protects against spina bifida. But large amounts of green tea could decrease the effectiveness of folic acid. http://www.healthypages.net/newsstory.asp?newsid=4947

Is Green Tea Dangerous to the Thyroid

by J. Shomon <http://thyroid.about.com/mbiopage.htm>March 2001 -- In response to my article on green tea as a weight loss aid <http://thyroid.about.com/library/weekly/aa030701a.htm>, some readers expressed concerns regarding the high fluoride content in tea, and the negative relationship between ingestion of too much fluoride and thyroid problems, as well as other health concerns.

This is definitely something to be considered before deciding to take green tea. While green tea has some definite benefits in the cancer-prevention and metabolism-boosting arena, the fluoride content may, according to some practitioners, be a concern for the public in general, but specifically for thyroid patients. For more information on the green tea/thyroid/fluoride connection, please see s Schuld's letter regarding the issue, which is online at his website.

Huh? I don't think I asked about green tea, did I? Maybe I hit my head when I fell yesterday!!

Thanks anyway, looks like good info.
