Querying Quercetin

Quercetin is a flavonoid (and thus, antioxidant) pigment found in many plants. Capers, radishes, and coriander/cilantro score highly, but the list is large:

USDA Database for the Flavonoid Content of Selected Foods

Indeed,

❝Their regular consumption is associated with reduced risk of a number of chronic diseases, including cancer, cardiovascular disease (CVD) and neurodegenerative disorders❞

~ Dr. Aleksandra Kozłpwsla & Dr. Dorota Szostak-Wegierek

For this reason, quercetin is often sold/consumed as a supplement on the strength of its health-giving properties.

But what does the science say?

Quercetin and inflammation

In short, it helps:

❝500 mg per day quercetin supplementation for 8 weeks resulted in significant improvements in clinical symptoms, disease activity, hs-TNFα, and Health Assessment Questionnaire scores in women with rheumatoid athritis

~ Dr. Fatemeh Javadi et al.

Quercetin and blood pressure

It works, if antihypertensive (i.e., blood pressure lowering) effect is what you want/need:

❝…significant effect of quercetin supplementation in the reduction of BP, possibly limited to, or greater with dosages of >500 mg/day.❞

~ Dr. Maria-Corina Serban et al.

Quercetin and diabetes

We’re less confident to claim this one, because (almost?) all of the research so far as been in non-human animals or in vitro. As one team of researchers put it:

❝Despite the wealth of in animal research results suggesting the anti-diabetic and its complications potential of quercetin, its efficacy in diabetic human subjects is yet to be explored❞

~ Dr. Guang-Jiang Shi et al.

Quercetin and neuroprotection

Research has been done into the effect of quercetin on the risk of Parkinson’s disease and Alzheimer’s disease, and they found…

❝The data indicate that quercetin is the major neuroprotective component in coffee against Parkinson’s disease and Alzheimer’s disease❞

~ Dr. Moonhee Lee et al.

Summary

Quercetin is a wonderful flavonoid that can be enjoyed as part of one’s diet and by supplementation. In terms of its popular health claims:

  • It has been found very effective for lowering inflammation
  • It has a moderate blood pressure lowering effect
  • It may have anti-diabetes potential, but the science is young
  • It has been found to have a potent neuroprotective effect

  • 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.
