Excessive black tea

Answered on August 19, 2014
Created May 29, 2013 at 3:20 PM

I drink 1-5 cups of black tea, usually strong, a day. 4-5 is more common than only 1. I realize that due to it's higher level of fermentation it has less anti-oxidants that green and especially white tea, but since I also drink those a few times per week I'm not too worried. I don't drink coffee nor obviously colas so I'm not too worried about the caffeine levels, or should I be? And what about possible other negative effects of such a constant high black tea intake?

(FWIW I generally have about a teaspoon of milk in each cup as well, my only dairy consumption.)

I'm kind of wary of anything to excess - beef, chicken, coffee, vegetables, supplements, even organic tea... I guess because I don't know what organic growing standards mean in china and India, or what the air and land quality is nearby and therefore what could get deposited on the plants, so just be aware, as always!

you might be fine now but a couple of years down the line...also make sure you're not iodine deficient because if you are fluoride will get taken up by the thyroid instead and you could end up hypothyroid...(happened to me, but I was also severly undernourished and deficient on probably every vitamin and mineral)

Thanks. A quick search of dietary folate sources shows me that I do in fact consume high daily amounts, particularily in egg yolk and salad greens. I also seem not exhibit any of the listed signs of folate depletion.

Have you seen this article?

http://well.blogs.nytimes.com/2013/05/23/whats-in-your-green-tea/

Do you use really REALLY high quality tea? If so, I'd be wary of taking so much tea (I know the article is about green tea but the same easily applies to black)...

I know the article says that you're fine unless you're eating the tea leaves concerning lead, but even so, I'm suspicious.

Just to be sure: we're not talking tiny, chinese style cups of tea, right? You're saying you drink 6 american, coffee cup sized cups of tea?

The other thing is that if you're deficient in iron, the tea will prevent any non-heme iron absorption.

The other thing is that if you have any kind of kidney problems, liver problems, etc. I would be wary because of other potential contaminants/pesticides/chemicals from the growing area (maybe China in most cases?):

It's an extreme case but here's a woman who experienced skeletal fluorosis from drinking lots of iced tea per day:

http://detroit.cbslocal.com/2013/03/24/460558/

Also, from this site: http://www.amazing-green-tea.com/drinking-too-much-green-tea.html

"Tea plant accumulates nutritions such as aluminium, manganese and fluoride from soil and water. These minerals can be harmful when consumed in large amounts over many years.

A 2005 study conducted by Dr. Michael Whyte from Washington University raised concerns about the high fluoride content in instant iced tea.

A middle aged woman diagnosed with skeletal fluorosis drank 17 to 33 cups a day, double-strength, because of the hot weather.

This is unusual, but highlight the dangers of drinking too much green tea."

So, just be careful and remember to buy really high quality black tea if you do wish to indulge, maybe try to use reverse osmosis water to make your tea to prevent too much fluoride (which can stain your teeth too).

Unless you're a kid, drinking so much fluoride doesn't really help your teeth anymore and your body has to plow through antioxidants and glutathione to process the fluoride...

It depends on what your concerns are, whether its affects are worse for your issues.

I, too, drink about 6C of black tea (can't do dairy at all, so I use soya -- how's that for rule-breaking? I use it for controlling an errant period; it's that or pop a big pharma pill).

People say it leeches calcium, of course, you're adding dairy, so that may even out. I also see concerns for its caffeine (it affects insulin and causes adrenal issues). You can find a lot of articles but this is a paleo-friendly discussion (though they're talking coffee).

While I have a cadre of autoimmune issues, I've tested tea and coffee (through food challenges during elimination testing). I seem to not have the 'addiction' issue when going off but I go off both a few times a year (believing it's probably good for me due to the adrenal thing).

I don't seem to react badly when I take either up again. However, I'd suggest you get really clean, 100% for a while and then try it yourself. Unless you have health issues that you know are made worse, it's about how you feel.

There are downsides to drinking that much black tea but I do okay with them.

You might need to maintain a higher intake of folate. The catechins in tea inhibit the uptake of folate in the intestines. Also might need to watch your cortisol levels. Black tea has a moderate amount of caffeine which could negatively effect your adrenal glands.
