Is Too Much Tea Bad For Your Health?

Is Too Much Tea Bad For Your Health?

A recent U.K. study looked at tea and health, and the results might surprise you.

Fluoride is a controversial compound. Here in the U.S., many municipalities add it to the water supply in the name of improving dental health, but some research suggests that too much fluoride could be bad for us. In fact, groups like Fluoride Out advocate against adding fluoride to drinking water for a slough of reasons. So, what does fluoride have to do with tea and health?

No matter what your stance is as far as fluoridated drinking water, there is strong evidence that too much fluoride can be detrimental to our health. More than 4mg per day can cause bone decay, muscle problems, and even chronic pain.

A U.K. study at the University of Derby found that many bulk brands of supermarket black tea contained 75 to 120 percent of your daily value of fluoride. Combine that with other fluoride sources, like fluoridated drinking water or toothpaste, and avid tea-drinkers could be taking in far more than the recommended dosage of fluoride.

Tea and Health

The study compared 38 brands of U.K. tea and found that “economy” teas and instant teas – especially supermarket brands – tended highest in fluoride. The supermarket brands they studied included Asda, Tesco, Morrisons and Sainsbury’s. Infused green tea blends were next highest on the list, with specialty teas like oolong following. closely behind.

This most recent study costs $42 to download, but you can check out excerpts of some previous research into tea and health over at Fluoride Action Network.

Unfortunately, companies don’t have to disclose fluoride levels as part of a product’s nutritional information, but as a result of this research experts are calling for a change in labeling laws.

Whatever is too much, is bad for our health :)

"People now receive fluoride from many other sources besides water. Fluoridated water is not the only way people are exposed to fluoride. Other sources of fluoride include food and beverages processed with fluoridated water (Kiritsy 1996; Heilman 1999), fluoridated dental products (Bentley 1999; Levy 1999), mechanically deboned meat (Fein 2001), tea (Levy 1999), and pesticide residues (e.g., from cryolite) on food (Stannard 1991; Burgstahler 1997). It is now widely acknowledged that exposure to non-water sources of fluoride has significantly increased since the water fluoridation program first began (NRC 2006)."

Um.... seriously Im not going to worry about this article and drink tea when I want too. We have fluoride in our water here and it appears that all of us have pretty good strong teeth etc.

Like are they suggesting people are drinking 20 cups a day? you'd pee yourself silly. I dont think that would happen anyway.

1) In places where flouride is naturally in water the people who live there have great teeth--yellow perhaps but healthy--it has been documented a thousand times over that flouride is good for your teeth. I do question how much is good for the rest of your body. 2) This is a terribly misleading headline! I and my family and friends drink lots of tea. I have never once had "bulk grocery store tea." So a small percentage of tea-drinkers should be concerned. On the flip side, tea has MANY health benefits. Great idea to scare off people from drinking one of the few relatively healthy drinks around. So we should quit drinking anything perhaps? That would certainly shorten our lifespans.

Let's apply a modicum of common sense to this ridiculous tea party. Scaremongering is at the heart of this post. It's all becoming too much. Drink tea if you like it, drink tea with fluoride if it suits you [your teeth will find it a blessing], drink anything else that takes your fancy and please, I beg of you all, STOP WORRYING UNNECESSARILY. The real truth is that worrying for no good reason is the biggest cause of premature death, also it makes its victims so bloody miserable. Ask any trick cyclist....

I only drink tea when I go out and it's included in the cost of my meal - but used to drink it a lot as a kid. Seems like nothing is good anymore.
