Antioxidants in green tea - helpful or not?

Green tea, thanks to its relatively high amount of antioxidants (which, depending from origin and processing, has a wide span) is highly prized as protection against numerous diseases. But is it true? Is green tea kind of a wonder-remedy? Sceptical as I am, especially when I see marketers pick up scientific research-results, I sat down and went through a whole bunch of those (not easy to read and understand!) researches/studies.

I was not surprised to find not any evidence that antioxidants in tea do what marketers promise (and what became "reality" by endless repeating by almost everybody who sells, buys or writes about tea). I sat down again and wrote the blog post "Antioxidants in green tea - bad news and good news", published on March 2nd in this blog.

To be sure that everything that I wrote is correct (and helpful) and for that it`s also correct "to put my foot on the green tea is not a wonder-remedy brake", I sent a request to the Linus Pauling Institute, to have a look on my findings, as reported in my last post. The Institute is specialized on micronutrients and a great source when it comes to reliable information about micronutrients in food. Here the response:

Dr. Delage reviewed your blog post.... We don't have any issues with the content; it is scientifically accurate. However, we suggest changing "flavanols" to "flavan-3-ols" in the sentence, "Catechins belong to flavanols, a subclass of flavonoids".

We have updated our Micronutrient Information Center articles on tea and flavonoids, but they are currently out for review by an expert and will be posted once reviewed.

Sincerely,

Conclusion: Antioxidant in green tea may have a positive effect on our health. But more research is needed. If it´s found one day that the regular consumption of green tea reduces the risk of getting cardiovascular or other diseases - great news! If not - let´s simply enjoy our daily "cup of Mary", be it made of green, black tea or whatever! (Oh yes, and I will change now "flavanols" to "flavan-3-ols".)
