The best tea, backed by science for optimal health.

What kind of tea is best for the health?

It’s popular knowledge that tea is a healthful drink, and green tea tends to get the popular credit for “healthiest”.

Is that accurate? It depends on what you’re looking for…

Black

Its strong flavor packs in lots of polyphenols, often more than other kinds of tea. This brings some great benefits:

As well as effects beyond the obvious:

…and its cardioprotective benefits aren’t just about lowering blood pressure; it improves triglyceride levels as well as improving the LDL to HDL ratio:

The effect of black tea on risk factors of cardiovascular disease in a normal population

Finally (we could say more, but we only have so much room), black tea usually has the highest caffeine content, compared to other teas.

That’s good or bad depending on your own physiology and preferences, of course.

White

White tea hasn’t been processed as much as other kinds, so this one keeps more of its antioxidants, but that doesn’t mean it comes out on top; in this study of 30 teas, the white tea options ranked in the mid-to-low 20s:

White tea is also unusual in its relatively high fluoride content, which is consider a good thing:

Green

Green tea ranks almost as high as black tea, on average, for polyphenols.

Its antioxidant powers have given it a considerable anti-cancer potential, too:

…and many others, but you get the idea. Notably:

…or to expand on that:

About green tea’s much higher levels of catechins, they also have a neuroprotective effect:

Green tea of course is also a great source of l-theanine, which we could write a whole main feature about, and we did:

Red

Also called “rooibos” or (literally translated from Afrikaans to English) “redbush”, it’s quite special in that despite being a “true tea” botanically and containing many of the same phytochemicals as the other teas, it has no caffeine.

There’s not nearly as much research for this as green tea, but here’s one that stood out:

Effects of rooibos (Aspalathus linearis) on oxidative stress and biochemical parameters in adults at risk for cardiovascular disease

However, in the search for the perfect cup of tea (in terms of phytochemical content), another set of researchers found:

❝The optimal cup was identified as sample steeped for 10 min or longer. The rooibos consumers did not consume it sufficiently, nor steeped it long enough. ❞

~ Dr. Hannelise Piek et al.

Bottom line

Black, white, green, and red teas all have their benefits, and ultimately the best one for you will probably be the one you enjoy drinking, and thus drink more of.

If trying to choose though, we offer the following summary:

  • 🖤Black tea: best for total beneficial phytochemicals
  • 🤍 White tea:best for your oral health
  • 💚 Green tea: best for your brain
  • ❤️ Red tea: best if you want naturally caffeine-free

  • Stop Cancer 20 Years Ago

    Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.

    Get Abreast And Keep Abreast

    This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.

    What does she want us to know?

    Start now

    If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.

    What this means for those of us without breast cancer (or a history therof) is: start now

    Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.

    Start what, you ask? Taking away its roots. And how?

    Inflammation as the root of cancer

    To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.

    Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:

    “and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”

    So, fight inflammation now, and have a reduced risk of a lot of other woes later.

    See: How to Prevent (or Reduce) Inflammation

    Don’t settle for “normal”

    People are told, correctly but not always helpfully, such things as:

    • It’s normal to have less energy at your age
    • It’s normal to have a weaker immune system at your age
    • It’s normal to be at a higher risk of diabetes, heart disease, etc

    …and many more. And these things are true! But that doesn’t mean we have to settle for them.

    We can be all the way over on the healthy end of the distribution curve. We can do that!

    (so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)

    If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.

    So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:

    See: Focusing On Health In Our Sixties

    Fast to live

    Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.

    This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.

    See: Intermittent Fasting: We Sort The Science From The Hype

    While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.

    It’s never too late

    All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”

    The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.

    Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.

    Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:

    1. Knowing stuff
    2. Doing stuff

    So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
