Is your teabag full of toxins?

It's relaxing... refreshing... and in these dog days of winter, it can really warm you up.

I'm talking about a steaming cup of tea.

And whether you prefer black, green, or herbal tea varieties, this ancient beverage is not only tasty -- it's practically "boiling over" with benefits for your body.

Time and again, studies have shown that regularly drinking tea can stave off diabetes, cancer, heart disease, and dementia... and it can shave off pounds, too.

It's even been shown to help keep your bones strong and healthy!

But according to a new study, there may be one caveat to tea's bone benefits.

Some teas are high in fluoride -- the same neurotoxin that's put into tap water and toothpaste to supposedly prevent your teeth from decaying.

And if you drink a lot of tea, all of that excess fluoride could deposit in your bones and cause a painful condition in your bones and joints called "skeletal fluorosis."

In the study, published in Environmental Pollution, researchers brewed up 47 different teas, including both traditional (black/green) and herbal varieties.

It turned out that about 20 percent of these brewed teas contained levels of fluoride that are nearly DOUBLE the maximum amount that is supposedly "safe" for you to have on a daily basis.

The feds over at the EPA have capped the amount of fluoride allowed in water at 4 mg per liter. And some of the teas in the study contained nearly as much as 7 mg per liter!

So, even if you've already switched to a fluoride-free toothpaste and mouthwash... and you've installed a reverse osmosis filtration system at the source of your water supply... you could STILL be getting exposed to this toxin at levels that exceed even what the notoriously permissive feds will allow!

At high levels, fluoride can threaten your bones, heart, liver, and kidneys, as well as your endocrine and nervous systems.

Now, I'm not suggesting that you quit drinking tea entirely -- because the potential benefits of tea are so numerous.

But there are some simple things that you can do to lower your risk of toxicity.

First off, people who get fluorosis from tea drink an awful lot of it -- we're talking 1 to 2 gallons a day for decades. So, use common sense... enjoy your tea in moderation!

Fortunately, not all teas contain fluoride -- or, at least, not as much as the teas in the study. The study found that the teas with the highest amounts of fluoride were also those of the lowest quality... and the oldest leaves.

So, you can dodge the toxic bullet by choosing younger tea leaves, like those found in so-called "white teas," from a high-quality brand. You may spend a little more, but the teas with the lowest amounts of fluoride also tend to have the highest levels of antioxidants.

You can also take your tea with a spot of fruit, because studies have also shown that lycopene -- an antioxidant found in red-hued fruits like tomatoes, pink grapefruit, and watermelon -- can reduce the damage from excess fluoride in your system.
