Lead Contamination of Tea
Subscribe to Dr. Greger’s free nutrition newsletter at http://www.nutritionfacts.org/subscribe and get a free excerpt from his latest NYT Bestseller HOW NOT TO DIE. (All proceeds Dr. Greger receives from his books, DVDs, and speaking go to charity). DESCRIPTION: At what level of tea consumption might the benefits of tea start to be countered by the risks of lead contamination for green, white, black, and oolong tea for children, pregnant women, and adults in general? This is one of the things that changed my daily diet. If you look at my smoothie recipe, for example (A Better Breakfast http://nutritionfacts.org/video/a-better-breakfast/), I’ve recommended throwing in tea leaves, and I’ve been a big fan of matcha (Is Matcha Good for You? http://nutritionfacts.org/video/is-matcha-good-for-you/). I still enjoy doing both, but am now more careful where my tea is sourced. Note, as soon as I learned of this I made announcements on Facebook (http://facebook.com/NutritionFacts.org), Twitter (http://twitter.com/nutrition_facts), and Google+ (https://plus.google.com/+NutritionfactsOrgMD/) to inform everyone before I even started making this video. So, if you closely follow my recommendations (which I elaborate on extensively in my new book How Not to Die http://nutritionfacts.org/book), please make sure to keep an eye on our social media where I can post things within minutes of learning about them. I’ve got a whole slew of new tea videos coming out, but here’s some of the ones I’ve done over the last year or two: • Is Caffeinated Tea Dehydrating?

"the use of coal in china has increased to 3.8 billion tons or about 47% of global coal consumption" Which article is that from? -it's not in Tang et al 2008 (as per vid)

Hello Dr. Greger, can you compare and contrast cold brewed versus hot brewed tea. I prefer cold brewed but am curious about the benefits of each.
-
So basically, Fuck Chinese Black Tea.
Thanks Doc appreciate the info and will utilize it when I go shopping for tea. -
I keep vommiting after drinking tea (about 20% of the time), and I thought it was the tannins. Could it be lead then?
-
Tea sounds unhealthy so I'll stick to a drop of whiskey to warm me up.
-
Can you do a video about avoiding parasites in organic fruit? Lol or am I being too much of a hypochondriac. Thanks in advance!
-
I drink hibiscus tea - it's lovely and looks like ribena

You'd think the entire population of England would be suffering from lead poisoning?
This reference was from 2003 ..It's 2016{ Was this reference Study done (With a bias) by persons interested in promoting green tea? Were the samples taken selectively by the researchers,from the plants (next to the highways)or from samples picked from the growers/producers;As Premium Black teas are all produced from young buds.
I'd have to see a second ,recent,unbiased,corroborating study before giving this any real credence.
This is all based on brewed tea ,What about cold steeped tea (Steeping overnight in cold water) Is the Hot Brewing process required to release the lead?
What about Assam- Black tea from India and Ceylon Black tea from Sri Lank ...No mention?(I want the Benefits of Tea and I don't like Green !) I guess I'll have to go with Assam and Ceylon Teas. -
Another great video. Thanks doc.
-
Well that really sucks - especially for is little ole southern belles
-
Considering Fukushima is still melting down, their secrecy regarding that, Japan would not be country of my choice for anything.
-
Looks like India and Sri Lanka are safer than Japan: http://www.hindawi.com/journals/jt/2013/370460/tab4/
-
thanks for making the numbers so visual!! love your channel!
-
amazing infos thx ^^
-
Cheers for home grown mint tea, happy healthy new year doc!
-
Ill stick too beer.

Turns out what you think is helping you could be doing more harm than good,like organic food produce is much more likely to contain harmful bacteria from animal feces sprayed on the produce,if I cook the food some of the enzymes are lost,this is a lose ,lose situation,it seems the only way to be totally safe is to grow your own food and most people don't want to do that.

ugh I thought about the market that I get my veggies from all those countries outside of the USA.....non USA veggies
-
No info on Indian Darjeeling, for example? Or Ceylon?
