Many studies recommend consuming a large quantity of tea daily to see health benefits. However, the quality of the tea may be the most important factor to consider since higher quality, loose leaf tea corresponds to minimizing toxins such as fluoride. Green, black, white and oolong teas naturally have differing levels of fluoride in the leaves.

Fluoride in Tea

As the controversy swells regarding fluoride in drinking water, it's important to look at our diet to minimize other sources of fluoride.

For some tea leaves, the fluoride content is high. The type of tea and quality of tea, however, determine the level of fluoride present. Making a healthier choice in tea will both minimize fluoride intake and maximize overall health benefits.

There are varying levels of fluoride in some popular teas: black tea, white tea, green tea and oolong tea. First you will want to understand the potential dangers of fluoride.

Less Fluoride in Young Tea Leaves

The Camellia sinensis plant is what produces the tea leaves for white, green, black and oolong teas. When this tea plant grows, the roots absorb fluoride from the soil and deposit the majority of it in the leaves.

The tea plant in particular is much more efficient at this process than other plants.

Since older, more mature leaves have had more time for this deposition, they contain up to 20 times more fluoride than younger tea leaves.

Anit-Oxidant EGCG Level in Tea Leaves

The powerful anti-oxidant epigallocatechin gallate (EGCG) present in tea is responsible for health benefits such as lowering LDL and has anti-cancer properties.

The level of EGCG decreases in more mature tea leaves, giving us further reason to prefer younger tea leaves.

Quality of Tea and Fluoride Content

Younger tea leaves are used in higher quality teas and contain lower fluoride levels.

See the list from highest quality to lowest quality.

1. Loose leaf tea ~ Best Quality
2. Tea dust (tea bags)
3. Bottled tea (fluoride in water plus fluoride in tea)
4. Brick tea (oldest leaves formed into brick shape) ~ Lowest Quality

Japanese green tea has lower levels of fluoride than Chinese green tea due to fluoride levels in soil aborbed by the tea plant.

Fluoride Content in Chinese Green Tea vs Japanese Green Tea

Soil in Japan is naturally lower in fluoride compared to China, according to the World Health Organization (WHO). Therefore, Japanese green tea will naturally have lower fluoride levels than Chinese green tea.

WHO lists several areas of the world where high naturally occurring fluoride concentrations affect tea crops and drinking water: India, Sri Lanka, parts of Africa and the Middle East (more information).

How To Brew Loose Leaf Tea

In case the idea of loose leaf tea is new to you, here's how you can incorporate this type of tea into your routine.

  1. Use a traditional teapot.

    Heat water with a tea kettle. Use the strainer basket or infuser on your teapot for the tea leaves. If you don't have a teapot with a strainer, place tea leaves directly in pot. Add the hot water from the tea kettle to the teapot. After the recommended steep time, remove the strainer basket or infuser or use a hand-held strainer to filter out the tea leaves while pouring into your cup.
  2. Use a tea maker.

    After heating water in a tea kettle, pour into the tea maker. Some tea makers have filters set into the pot for the leaves and others filter as you pour the tea out.
  3. Use individual tea filters or tea ball.

    Use water heated in a tea kettle to pour into your tea cup containing a tea filter (is basically a tea bag that you have filled yourself) or tea ball that you filled with loose leaf tea. Some brands sell loose leaf tea already in sachets.

Loose leaf tea is higher quality which corresponds to lower toxins and more health benefits.

So... What is the Healthiest Type of Tea?

We should be limiting our total exposure to fluoride from tea, based on the potential dangers associated with fluoride exposure and the high levels present in many types of tea. At the same time, incorporating benefits from different types of teas provides a wide variety of benefits.

  • White tea is a true tea that contains high antioxidant power and has low fluoride levels, especially in loose-leaf form.
  • Green tea health benefits are well-studied. To incorporate benefits of green tea in the diet, finding a loose leaf option from Japan or a loose leaf option with younger leaves will limit fluoride while providing benefit.
  • Loose-leaf black tea and oolong tea from areas with lower environmental fluoride are best if you prefer black or oolong tea.
  • The fluoride-free options are herbal teas, but then the health benefits from true tea are not felt.

If you are really more of a coffee drinker, find out about toxins and health benefits of different types of coffee.

      I've even heard that drinking too much green tea is bad for you. There was a teenage girl in the UK, I think, who recently got jaundice and liver problems from too much matcha tea intake.

      Thanks for that information Jonathan. Fluoride also binds to calcium in the diet.

      Good amounts of Iodine might help with Fluoride issues. So eating plenty of seafood that has a good Selenium to Mercury ratio would be good.

      Selenium matters because if you have enough Selenium it binds to the Mercury thus making it benign. What makes Mercury such a problem is that it can muck up the works by binding to receptors. It can't do that if its already bound to Selenium.

      Things like Shark, Swordfish, some types of Tuna have more Mercury than Selenium.

      I'm not surprised you found relief from asthma symptoms by eliminating toxins freda. I'm wondering if you would still be able to drink white tea or herbal tea as the levels of fluoride are reported to be significantly lower for white and none for herbal except what you would get from your water source.

      im sorry to say that in my personal quest to improve asthma, by removing as much fluoride as i can from my body, i have given up tea. but i love the effects of tea so now i buy L-Theanine.

      I actually find a dose of Theanine to be better than tea in term of the mental facilitation, but i do miss the warm stimulating beverage. Hopefully one day we have growers who actively control the level of toxic elements.

      That is exactly the problem Brett. Quality leaves provide such a great benefit. Unfortunately, the convenience in tea has lead to less quality and thus less benefits.

      Green tea is actually very nice. It is extremely popular in Thailand and the older generation still brew from fresh leaves. However, unfortunately the presence of convenience stores now has lead to more and more buying instant versions ... which I doubt have the benefits and probably get loaded with chemicals.

      SHARED, up and interesting.

      Thanks Arnold for your comment.

      The UK Department of Health commissioned a study in 2004 from which they concluded there is no difference in the bioavailability of fluoride from 'natural sources' versus artificial fluoride compounds. The Australian Dental Association references this study http://www.ada.org.au/oralhealth/fln/flfaqs.aspx#F...

      One of my other hubs titled 'Drinking Water Fluoridation and Dental Fluorosis' (link above) touches on the different fluoride compounds that are by-products of the fertilizer industry. These compounds, when added to the drinking water, dissolve in water, separating the element of fluoride from the other contaminants to act within the body once ingested (these by-products are contaminated with other chemicals as you mentioned).

      Also discussed in my other hub ~ different ways that fluoride is used to help teeth. Ingesting fluoride, no matter which form, can be toxic. However, topically applying fluoride has been shown to help prevent cavities.

      Although other minerals such as calcium can bind to fluoride compounds so they are not used by the body, there needs to be enough calcium ingested along with the fluoride during the same meal. In the case of tea, calcium may also bind to some of the beneficial components of tea.

      I appreciate the points you brought up Arnold ~ all good topics to explore.

      The chemical properties of the fluoride naturally absorbed in through the root structure are much different and safer than the added fluoride, usually hydrofuslic acid obtained from the industrial wastes of phosphate fertilizer and aluminum plants.Where fluoride trace elements occur in nature thet usually are counterbalanced with healthy trace minerals such as magnesium and calcium.

      Mekenzie ~ I'm glad you brought up the issue of organic since, like you said, it has nothing to do with the fluoride that the tea plant absorbs from the soil. In a general sense, India does have high levels of fluroide in the soil according to WHO (see link in text to see more specifics and other countries listed). For herbal tea and white tea, the fluoride is low to absent anyway so the country of origin doesn't matter as much as green, black or oolong for example.

      Cheers ~ Melis Ann

      Once again you have taught me something I did not know. I have always bought organic teas (and coffee) such as Organic India teas because I have a concern about the chemicals used on tea leaves. I never thought about fluoride in tea. What do you know about tea grown in India?

      Thanks!
