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

  • Glucomannan For Weight Loss, Gut Health, & More

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Glucomannan is a water-soluble dietary fiber found in the root of the konjac plant.

    If you’ve had konjac noodles, also called shirataki, that’s what those are mostly made of, and it’s why they have next-to-no calories.

    You may be wondering: if it’s water-soluble, how do the noodles not dissolve in water? And the answer is that the noodle-making process involves making a gel out of the fiber and water, which is then extruded into noodle shapes. In this gelatinous form, they’re fairly stable (it’s one of the most viscous dietary fibers), but yes, if you were to boil them for a long time, they would indeed turn the entire liquid contents of the saucepan into gel.

    How it works for weight loss

    Because of its viscosity, adding even a small amount of powdered* glucomannan to a glass of water will turn the whole thing into gel in seconds. This means that if you take glucomannan capsules with a glass of water, then so far as your stomach is concerned, you just ate a cup of gel, and the water is now processed as food, staying longer in the stomach than it otherwise would, and promoting feelings of fullness.

    *i.e. dry powder, not in a gelatinous form like the noodles

    As for its efficacy in weight loss, see for example:

    ❝Glucomannan was well-tolerated and resulted in significant weight loss in overweight and obese individuals❞

    Read more: Glucomannan and obesity: a critical review

    So, that covers the basic requirements, but may be wondering: does it have other benefits? And the answer is yes, it does:

    ❝Glucomannan appears to beneficially affect total cholesterol, LDL cholesterol, triglycerides, body weight, and fasting blood glucose❞

    Read more: Effect of glucomannan on plasma lipid and glucose concentrations, body weight, and blood pressure: systematic review and meta-analysis

    To further corroborate that and comment on safety…

    ❝Results showed a significant mean weight loss using glucomannan over an eight-week period. Serum cholesterol and low-density lipoprotein cholesterol were significantly reduced in the glucomannan treated group. No adverse reactions to glucomannan were reported.❞

    Read more: Effect of glucomannan on obese patients: a clinical study

    As to whether other gel-making agents work the same way, the answer is no, they don’t seem to:

    ❝Glucomannan induced body weight reduction in healthy overweight subjects, whereas the addition of guar gum and alginate did not seem to cause additional loss of weight❞

    Read more: Experiences with three different fiber supplements in weight reduction

    How it works for gut health

    In the words of Dr. Yu Li et al.,

    ❝Konjaku flour can achieve positive effects on treating obesity, which manifest on reducing BMI, fat mass, blood glucose, and blood lipid, improving hepatic function, and also regulating intestinal microfloral structure.

    Therefore, changes in gut microbiota may explain in part the effects of konjaku flour.❞

    This has extra positive knock-on effects too:

  • The Blood Sugar Solution – by Dr. Mark Hyman

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    The main purpose of this book is combating metabolic disease, the amalgam of what’s often prediabetes (sometimes fully-fledged diabetes) and cardiovascular disease (sometimes fully-fledged heart disease).

    To achieve this (after an introductory section explaining what the sociomedical problems are and why the sociomedical problems are happening), he offers a seven-step program; we’ll not keep those steps a mystery; they are:

    1. Boost your nutrition
    2. Regulate your hormones
    3. Reduce inflammation
    4. Improve your digestion
    5. Maximize detoxification
    6. Enhance energy metabolism
    7. Soothe your mind

    Thereafter, it’s all about leading the reader by the hand through the steps; he also offers a six-week action plan, and a six-week meal plan with recipes.

    The style is very sensationalist (too sensationalist for this reviewer’s personal taste) but nevertheless backed up with hard science when it comes to hard claims. So, if you don’t mind wading through (or skipping) some early chapters that are a bit “used car salesman” in feel, there’s actually a lot of good information, especially in the middle of the book, and useful practical guides in the middle and end.

    Bottom line: if you want a good comprehensive science-based practical guide to addressing the risk of metabolic disease, this is that.

  • Red Light, Go!

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Casting Yourself In A Healthier Light

    In Tuesday’s newsletter, we asked you for your opinion of red light therapy (henceforth: RLT), and got the above-depicted, below-described, set of responses:

    • About 51% said “I have no idea whether light therapy works or not”
    • About 24% said “Red light therapy is a valuable skin rejuvenation therapy”
    • About 23% said “I have not previously heard of red light therapy”
    • One (1) person said: “Red light therapy is a scam to sell shiny gadgets”

    A number of subscribers wrote with personal anecdotes of using red light therapy to beneficial effect, for example:

    ❝My husband used red light therapy after surgery on his hand. It did seem to speed healing of the incision and there is very minimal scarring. I would like to know if the red light really helped or if he was just lucky❞

    ~ 10almonds subscriber

    And one wrote to report having observed mixed results amongst friends, per:

    ❝Some people it works, others I’ve seen it breaks them out❞

    ~ 10almonds subscriber

    So, what does the science say?

    RLT rejuvenates skin, insofar as it reduces wrinkles and fine lines: True or False?

    True! This one’s pretty clear-cut, so we’ll just give one example study of many, which found:

    ❝The treated subjects experienced significantly improved skin complexion and skin feeling, profilometrically assessed skin roughness, and ultrasonographically measured collagen density.

    The blinded clinical evaluation of photographs confirmed significant improvement in the intervention groups compared with the control❞

    ~ Dr. Alexander Wunsch & Dr. Karsten Matuschka

    Read in full: A Controlled Trial to Determine the Efficacy of Red and Near-Infrared Light Treatment in Patient Satisfaction, Reduction of Fine Lines, Wrinkles, Skin Roughness, and Intradermal Collagen Density Increase

    RLT helps speed up healing of wounds: True or False?

    True! There is less science for this than the above claim, but the studies that have been done are quite compelling, for example this NASA technology study found that…

    ❝LED produced improvement of greater than 40% in musculoskeletal training injuries in Navy SEAL team members, and decreased wound healing time in crew members aboard a U.S. Naval submarine.❞

    ~ Dr. Harry Whelan et al.

    Read more: Effect of NASA light-emitting diode irradiation on wound healing

    RLT’s benefits are only skin-deep: True or False?

    False, probably, but we’d love to see more science for this, to be sure.

    However, it does look like wavelengths in the near-infrared spectrum reduce the abnormal tau protein and neurofibrillary tangles associated with Alzheimer’s disease, resulting in increased blood flow to the brain, and a decrease in neuroinflammation:

    Therapeutic Potential of Photobiomodulation In Alzheimer’s Disease: A Systematic Review

    Would you like to try RLT for yourself?

    There are some contraindications, for example:

    • if you have photosensitivity (for obvious reasons)
    • if you have Lupus (mostly because of the above)
    • if you have hyperthyroidism (because if you use RLT to your neck as well as face, it may help stimulate thyroid function, which in your case is not what you want)

    As ever, please check with your own doctor if you’re not completely sure; we can’t cover all bases here, and cannot speak for your individual circumstances.

    For most people though, it’s very safe, and if you’d like to try it, here’s an example product on Amazon, and by all means do read reviews and shop around for the ideal device for you

    Take care! 😎

    Q&A with the 10almonds Team

    Q: Very interested in this article on CBD oil in the states. hope you do another one in the future with more studies done on people and more information on what’s new as far as CBD oil goes

    A: We’re glad you enjoyed it! We’ll be sure to revisit CBD in the future—partly because it was a very popular article, and partly because, as noted, there is a lot going on there, research-wise!

    And yes, we prefer human studies rather than mouse/rat studies where possible, too, and try to include those where we find them. In some cases, non-human animal studies allow us to know things that we can’t know from human studies… because a research institution’s ethics board will greenlight things for mice that it’d never* greenlight for humans.

    Especially: things that for non-human animals are considered “introduction of external stressors” while the same things done to humans would be unequivocally called “torture”.

    Animal testing in general is of course a moral quagmire, precisely because of the suffering it causes for animals, while the research results (hopefully) can be brought to bear to reduce to suffering of humans. We’re a health and productivity newsletter, not a philosophical publication, but all this to say: we’re mindful of such too.

    And yes, we agree, when studies are available on humans, they’re always going to be better than the same study done on mice and rats.

    As a topical aside, did you know there’s a monument to laboratory mice and all they’ve (however unintentionally) done for us?

    ❝The quirky statue depicts an anthropomorphic mouse as an elderly woman, complete with glasses balanced atop its nose. Emerging from two knitting needles in its hands is the recognizable double-helix of a strand of DNA.❞

  • Eat To Beat Chronic Fatigue!

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    How To Eat To Beat Chronic Fatigue

    Chronic fatigue is on the rise, and it can make life a living Hell. Days blur into one, and you try to take each day as it comes, but sometimes several days gang up on you at once.

    You probably know some lifestyle changes that might help—if only you had the energy to implement them.

    You’d like to eat well, but you need to…

    1. Buy the fresh produce (and take a little rest after)
    2. Put the groceries away (and take a little rest after)
    3. Wash the vegetables (and take a little rest after)
    4. Chop the things as necessary (and take a little rest after)
    5. Cook dinner (and take a little rest after)

    …and now you’re too exhausted to eat it.

    So, what can be done?

    First, avoid things that cause inflammation, as this is a major contributor to chronic fatigue. You might like our previous main feature:

    Keep Inflammation At Bay!

    Next up, really do stay hydrated. It’s less about quantity, and more about ubiquity. Hydrate often.

    Best is if you always have some (hydrating) drink on the go.

    Do experiment with your diet, and/but keep a food journal of what you eat and how you feel 30–60 minutes after eating it. Only make one change at a time, otherwise you won’t know which change made the difference.

    Notice what patterns emerge over time, and adjust your ingredients accordingly.

    Limit your caffeine intake. We know that sometimes it seems like the only way to get through the day, but you will always crash later, because it was only ever taxing your adrenal system (thus: making you more tired in the long run) and pulling the wool over the eyes of your adenosine receptors (blocking you from feeling how tired you are, but not actually reducing your body’s tiredness).

    Put simply, caffeine is the “payday loan” of energy.

    Eat more non-starchy vegetables, and enjoy healthy fats. Those healthy fats can come from nuts and seeds, avocado, or fish (not fried, though!).

    The non-starchy vegetables will boost your vitamins and fiber while being easy on your beleaguered metabolism, while the healthy fats will perk up your energy levels without spiking insulin like sugars would.

    Pay the fatigue tax up front. What this means is… Instead of throwing away vegetables that didn’t get used because it would take too much effort and you just need an easier dinner today, buy ready-chopped vegetables, for example.

    And if you buy vegetables frozen, they’re also often not only cheaper, but also (counterintuitively) contain more nutrients.

    A note of distinction:

    Many more people have chronic fatigue (the symptom: being exhausted all the time) than have chronic fatigue syndrome (the illness: myalgic encephalomyelitis).

    This is because fatigue can be a symptom of many, many other conditions, and can be heavily influenced by lifestyle factors too.

    A lot of the advice for dealing with chronic fatigue is often the same in both cases, but some will be different, because for example:

    • If your fatigue is from some other condition, that condition probably impacts what lifestyle factors you are (and are not) able to change, too
    • If your fatigue is from lifestyle factors, that hopefully means you can change those and enjoy less fatigue…
      • But if it’s not from lifestyle factors, as in ME/CFS, then advice to “exercise more” etc is not going to help so much.

    There are ways to know the difference though:

  • Oven-Roasted Ratatouille

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    This is a supremely low-effort, high-yield dish. It’s a nutritional tour-de-force, and very pleasing to the tastebuds too. We use flageolet beans in this recipe; they are small immature kidney beans. If they’re not available, using kidney beans or really any other legume is fine.

    You will need

    • 2 large zucchini, sliced
    • 2 red peppers, sliced
    • 1 large eggplant, sliced and cut into semicircles
    • 1 red onion, thinly sliced
    • 2 cans chopped tomatoes
    • 2 cans flageolet beans, drained and rinsed (or 2 cups same, cooked, drained, and rinsed)
    • ½ bulb garlic, crushed
    • 2 tbsp extra virgin olive oil
    • 1 tbsp balsamic vinegar
    • 1 tbsp black pepper, coarse ground
    • 1 tbsp nutritional yeast
    • 1 tbsp red chili pepper flakes (omit or adjust per your heat preferences)
    • ½ tsp MSG or 1 tsp low-sodium salt
    • Mixed herbs, per your preference. It’s hard to go wrong with this one, but we suggest leaning towards either basil and oregano or rosemary and thyme. We also suggest having some finely chopped to go into the dish, and some held back to go on the dish as a garnish.

    Method

    (we suggest you read everything at least once before doing anything)

    1) Preheat the oven to 350℉ / 180℃.

    2) Mix all the ingredients (except the tomatoes and herbs) in a big mixing bowl, ensuring even distribution.

    2) Add the tomatoes. The reason we didn’t add these before is because it would interfere with the oil being distributed evenly across the vegetables.

    3) Transfer to a deep-walled oven tray or an ovenproof dish, and roast for 30 minutes.

    4) Stir, add the chopped herbs, stir again, and return to the oven for another 30 minutes.

    5) Serve (hot or cold), adding any herb garnish you wish to use.

    Enjoy!
