Could the fallout from fukushima be present in Japanese tea?
This by far has been one of the best thought out and edited informative video i have come across, with actual governmental studies and paperwork in the video. Thank you.
Why the hell is there lead in the tea in the first place??
What about Sri Lankan tea (Ceylon Tea)?
So regarding food contamination, what happens with the other half of the world's coal, burned by the US for electricity?
What about teas grown in Hawaii? I saw a Prop 66 on Hawaii Tea Company’s tea bags. Should I be concerned?
excellent info
Does anyone have a good Japanese brand they can recommend?
I’m a green tea addict. I buy expensive Rishi whole leave sencha tea coming from Japan and also eat the leaves. Apparently, there’s a pregnancy concern related to green tea consumption and its antifolate properties. Here it’s said green tea interfeares with folate absorption leading to a reduction of folate levels crucial during pregnancy: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4557736/ any thoughts/recommendations? I wonder if Dr Gregor could elaborate/ comment on the subject. Thanks
What about Darjeeling black tea cultivated in India? Also, does it matter if it's organic black tea?
So…Avoid Chinese and blacks. Got it.
Very informative well made.
Crazy we have to worry about heavy metals in foods and drinks. What a world

Does decaf green tea have health benefitsAs well?
What about Sri Lanka black tea? đŸ™‚
Are there any data from black teas grown in India or Sri Lanka?
Recommended lead? Isn't any amount of lead dangerous to the human body?
How much lead (ppm or ppb) is normal in green tea leaves?
I think you have some good points in here, and I do think it's good to be cautious of these things, but I want to challenge one particular idea you voice.
I'm the editor of RateTea and have researched these topics a fair amount. I think you communicate some misconceptions in how you handle or discuss black tea vs. green and white tea. You say that young leaves are used to make green and white tea, and older leaves are used to make black tea. This is not true as a general rule. Green, white, and black tea differ by production, not portion of tips. The portion of tips / leaf buds and age of the leaves is a function of the tea's grade, or how "tippy" the tea is. There are tippy white teas (silver needle) and tippy black teas (high grades like FTGFOP1, Yunnan Pure Gold, etc) and there are white teas made of mature leaves (Shou Mei or Precious Eyebrows) as well as black teas (Lapsang Souchong, any generic low grades of black tea).
Each type of tea, green tea, black, or white, is diverse, both in terms of the portion of tips, and other factors in production that would influence the risk of contamination by lead or other heavy metals. I would not conclude anything about the lead content of various types of tea unless you've actually studied or tested it, or found reliable studies that do this.
There are some good reasons to prefer tippy teas…but…they also can be MUCH higher in caffeine, which is one reason that people sometimes want to avoid them.
Is Moringa Tree Leaves Tea safe to drink?
I prefer to not drink Japanese tea. In fact: I avoid any East Asian tea nowaydays.
Dang, I bought a big bag of tea from China…. sigh
Thanks for information!
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.
I wouldn't ingest anything from Japan. China is pretty bad too. Stick to your own Country if it's safe. Better yet, if possible, grow your own food with non GMO seeds or go without. Stay away from seafood altogether.
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!
