Reishi Mushrooms
Another Monday Research Review, another mushroom! If we keep this up, we’ll have to rename it “Mushroom Monday”.
But, there’s so much room for things to say, and these are fun guys to write about, as we check the science for any spore’ious claims…
Why do people take reishi?
Popular health claims for the reishi mushroom include:
- Immune health
- Cardiovascular health
- Protection against cancer
- Antioxidant qualities
- Reduced fatigue and anxiety
And does the science agree?
Let’s take a look, claim by claim:
Immune health
A lot of research for this has been in vitro (ie, with cell cultures in labs), but promising, for example:
Immunomodulating Effect of Ganoderma lucidum (Lingzhi) and Possible Mechanism
(that is the botanical name for reishi, and the Chinese name for it, by the way)
That’s not to say there are no human studies though; here it was found to boost T-cell production in stressed athletes:
Cardiovascular health
Here we found a stack of evidence for statistically insignificant improvements in assorted measures of cardiovascular health, and some studies where reishi did not outperform placebo.
Because the studies were really not that compelling, instead of taking up room (and your time) with them, we’re going to move onto more compelling, exciting science, such as…
Protection against cancer
There’s a lot of high quality research for this, and a lot of good results. The body of evidence here is so large that even back as far as 2005, the question was no longer “does it work” or even “how does it work”, but rather “we need more clinical studies to find the best doses”. Researchers even added:
❝At present, lingzhi is a health food supplement to support cancer patients, yet the evidence supporting the potential of direct in vivo anticancer effects should not be underestimated.❞
Check it out:
Anticancer effects of Ganoderma lucidum: a review of scientific evidence
Just so you know we’re not kidding about the weight of evidence, let’s drop a few extra sources:
- Ganoderma lucidum: a rational pharmacological approach to surmount cancer
- Ganoderma lucidum as an anti-cancer agent
- Extract from Ganoderma lucidum suppresses cervical cancer cell malignancy
- Ganoderma lucidum spore oil induces apoptosis of breast cancer cells
- Ganoderma lucidum enhances carboplatin chemotherapy effect
- Ganoderma lucidum inhibits prostate cancer cell migration
- Ganoderma lucidum fruiting body extracts inhibit colorectal cancer
- Inhibitory activity of medicinal mushroom Ganoderma lucidum on colorectal cancer
- Ganoderma lucidum (reishi mushroom) for cancer treatment
By the way, we shortened most of those titles for brevity, but almost all of the continued with “by” followed by a one-liner of how it does it.
So it’s not a “mysterious action” thing, it’s a “this is a very potent medicine and we know how it works” thing.
Antioxidant qualities
Here we literally only found studies to say no change was found, one that found a slight increase of antioxidant levels in urine. It’s worth noting that levels of a given thing (or its metabolites, in the case of some things) in urine are often quite unhelpful regards knowing what’s going on in the body, because we get to measure only what the body lost, not what it gained/kept.
So again, let’s press on:
Reduced fatigue and anxiety
Most of the studies for this that we could find pertained to health-related quality of life for cancer patients specifically, so (while they universally give glowing reports of reishi’s benefits to health and happiness of cancer patients), that’s a confounding factor when it comes to isolating its effects on reduction of fatigue and anxiety in people without cancer.
Here’s one that looked at it in the case of reduction of fatigue, anxiety, and other factors, in patients without cancer (but with neurathenia), in which they found it was “significantly superior to placebo with respect to the clinical improvement of symptoms”.
Summary:
- Reishi mushroom’s anti-cancer properties are very, very clear
- There is also good science to back immune health claims
- It also has been found to significantly reduce fatigue and anxiety in unwell patients (we’d love to see more studies on its benefits in otherwise healthy people, though)

Keep Inflammation At Bay
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 Prevent (or Reduce) Inflammation
You asked us to do a main feature on inflammation, so here we go!
Before we start, it’s worth noting an important difference between acute and chronic inflammation:
- Acute inflammation is generally when the body detects some invader, and goes to war against it. This (except in cases such as allergic responses) is usually helpful.
- Chronic inflammation is generally when the body does a civil war. This is almost never helpful.
We’ll be tackling the latter, which frees up your body’s resources to do better at the former.
First, the obvious…
These five things are as important for this as they are for most things:
- Get a good diet—the Mediterranean diet is once again a top-scorer
- Exercise—move and stretch your body; don’t overdo it, but do what you reasonably can, or the inflammation will get worse.
- Reduce (or ideally eliminate) alcohol consumption. When in pain, it’s easy to turn to the bottle, and say “isn’t this one of red wine’s benefits?” (it isn’t, functionally*). Alcohol will cause your inflammation to flare up like little else.
- Don’t smoke—it’s bad for everything, and that goes for inflammation too.
- Get good sleep. Obviously this can be difficult with chronic pain, but do take your sleep seriously. For example, invest in a good mattress, nice bedding, a good bedtime routine, etc.
*Resveratrol (which is a polyphenol, by the way), famously found in red wine, does have anti-inflammatory properties. However, to get enough resveratrol to be of benefit would require drinking far more wine than will be good for your inflammation or, indeed, the rest of you. So if you’d like resveratrol benefits, consider taking it as a supplement. Superficially it doesn’t seem as much fun as drinking red wine, but we assure you that the results will be much more fun than the inflammation flare-up after drinking.
About the Mediterranean Diet for this…
There are many causes of chronic inflammation, but here are some studies done with some of the most common ones:
- Beneficial effect of Mediterranean diet in systemic lupus erythematosus patients
- How the Mediterranean diet and some of its components modulate inflammatory pathways in arthritis
- The effects of the Mediterranean diet on biomarkers of vascular wall inflammation and plaque vulnerability in subjects with high risk for cardiovascular disease
- Adherence to Mediterranean diet and 10-year incidence of diabetes: correlations with inflammatory and oxidative stress biomarkers*
*Type 1 diabetes is a congenital autoimmune disorder, as the pancreas goes to war with itself. Type 2 diabetes is different, being a) acquired and b) primarily about insulin resistance, and/but this is related to chronic inflammation regardless. It is also possible to have T1D and go on to develop insulin resistance, and that’s very bad, and/but beyond the scope of today’s newsletter, in which we are focusing on the inflammation aspects.
Some specific foods to eat or avoid…
Eat these:
- Leafy greens
- Cruciferous vegetables
- Tomatoes
- Fruits in general (berries in particular)
- Healthy fats, e.g. olives and olive oil
- Almonds and other nuts
- Dark chocolate (choose high cocoa, low sugar)
Avoid these:
- Processed meats (absolute worst offenders are hot dogs, followed by sausages in general)
- Red meats
- Sugar (includes most fruit juices, but not most actual fruits—the difference with actual fruits is they still contain plenty of fiber, and in many cases, antioxidants/polyphenols that reduce inflammation)
- Dairy products (unless fermented, in which case it seems to be at worst neutral, sometimes even a benefit, in moderation)
- White flour (and white flour products, e.g. white bread, white pasta, etc)
- Processed vegetable oils

Supplements?
Some supplements that have been found to reduce inflammation include:
(links are to studies showing their efficacy)
Consider Intermittent Fasting
Remember when we talked about the difference between acute and chronic inflammation? It’s fair to wonder “if I reduce my inflammatory response, will I be weakening my immune system?”, and the answer is: generally, no.
Often, as with the above supplements and dietary considerations, reducing inflammation actually results in a better immune response when it’s actually needed! This is because your immune system works better when it hasn’t been working in overdrive constantly.
Here’s another good example: intermittent fasting reduces the number of circulating monocytes (a way of measuring inflammation) in healthy humans—but doesn‘t compromise antimicrobial (e.g. against bacteria and viruses) immune response.
See for yourself: Dietary Intake Regulates the Circulating Inflammatory Monocyte Pool ← the study is about the anti-inflammatory effects of fasting

Small Changes For A Healthier Life

It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
I am interested in what I can substitute for ham in bean soup?
Well, that depends on what the ham was like! You can certainly buy ready-made vegan lardons (i.e. small bacon/ham bits, often in tiny cubes or similar) in any reasonably-sized supermarket. Being processed, they’re not amazing for the health, but are still an improvement on pork.
Alternatively, you can make your own seitan! Again, seitan is really not a health food, but again, it’s still relatively less bad than pork (unless you are allergic to gluten, in which case, definitely skip this one).
Alternatively alternatively, in a soup that already contains beans (so the protein element is already covered), you could just skip the ham as an added ingredient, and instead bring the extra flavor by means of a little salt, a little yeast extract (if you don’t like yeast extract, don’t worry, it won’t taste like it if you just use a teaspoon in a big pot, or half a teaspoon in a smaller pot), and a little smoked paprika. If you want to go healthier, you can swap out the salt for MSG, which enhances flavor in a similar fashion while containing less sodium.
Wondering about the health aspects of MSG? Check out our main feature on this, from last month:
I thoroughly enjoy your daily delivery. I’d love to see one for teens too!
That’s great to hear! The average age of our subscribers is generally rather older, but it’s good to know there’s an interest in topics for younger people. We’ll bear that in mind, and see what we can do to cater to that without alienating our older readers!
That said: it’s never too soon to be learning about stuff that affects us when we’re older—there are lifestyle factors at 20 that affect Alzheimer’s risk at 60, for example (e.g. drinking—excessive drinking at 20* is correlated to higher Alzheimer’s risk at 60).
*This one may be less of an issue for our US readers, since the US doesn’t have nearly as much of a culture of drinking under 21 as some places. Compare for example with general European practices of drinking moderately from the mid-teens, or the (happily, diminishing—but historically notable) British practice of drinking heavily from the mid-teens.
How much turmeric should I take each day?
Dr. Michael Greger’s research (of “Dr. Greger’s Daily Dozen” and “How Not To Die” fame) recommends getting at least ¼ tsp turmeric per day
Remember to take it with black pepper though, for a 2000% absorption bonus!
A great way to get it, if you don’t want to take capsules and don’t want to eat spicy food every day, is to throw a teaspoon of turmeric in when making a pot of (we recommend wholegrain!) rice. Turmeric is very water-soluble, so it’ll be transferred into the rice easily during cooking. It’ll make the rice a nice golden yellow color, and/but won’t noticeably change the taste.
Again remember to throw in some black pepper, and if you really want to boost the nutritional content,some chia seeds are a great addition too (they’ll get cooked with the rice and so it won’t be like eating seeds later, but the nutrients will be there in the rice dish).
You can do the same with par-boiled potatoes or other root vegetables, but because cooking those has water to be thrown away at the end (unlike rice), you’ll lose some turmeric in the water.
Request: more people need to be aware of suicidal tendencies and what they can do to ward them off
That’s certainly a very important topic! We’ll cover that properly in one of our Psychology Sunday editions. In the meantime, we’ll mention a previous special that we did, that was mostly about handling depression (in oneself or a loved one), and obviously there’s a degree of crossover:

Does Your Butt…Wink?
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.
What is a Butt Wink?
A “butt wink” is a common issue that occurs during squatting exercises.
Now, we’ve talked about the benefits of squatting countless times (see here or here for just a few examples). As with all exercises, using the correct technique is imperative, helping to both reduce injury and maximize gain.
Given butt winks are a common issue when squatting, we thought it natural to devote an article to it.
So, a butt wink happens when, at the bottom of your squat position, your pelvis tucks rotates backward (otherwise known as a “posterior pelvic tilt”) and the lower back rounds. This motion looks like a slight ‘wink’, hence the name.
How to Avoid Butt Winking
When the pelvis tucks under and the spine rounds, it can put undue pressure on the lumbar discs. This is especially risky when squatting with weights, as it can exacerbate the stress on the spine.
To avoid a butt wink, it’s important to maintain a neutral spine throughout the squat and to work on flexibility and strength in the hips, glutes, and hamstrings. Adjusting the stance width or foot angle during squats can also help in maintaining proper form.
A visual representation would likely work better than our attempt at describing what to do, so without further ado, here’s today’s video:

True Age – by Dr. Morgan Levine
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.
Yesterday’s book review (Counterclockwise) was about psychological factors affecting physical aging (progression or reversal thereof); today we have a book about the physiological factors affecting physical aging (progression or reversal thereof).
Dr. Levine is first and foremost a gerontological epigeneticist, and a lot of this book touches on her research in that field and that of her colleagues.
She does also discuss direct environmental factors also though, and—as you might well expect—lifestyle factors.
Regular readers of 10almonds are unlikely to gain anything new in the category of lifestyle matters, but a lot of the other material will be enlightening, especially with regard to the things that might at first glance seem set in stone, but we can in fact modify, and thus “choose our own adventure” when it comes to how the rest of our life plays out, healthwise (so: choose wisely!).
The book is mostly an overview on the (at time of writing: 2022) current state of affairs in the world of longevity research, and although it’s not a “how to” manual, there is plenty in the category of practical takeaways to be gleaned too.
The style is is mostly light pop science, but with a lot of hard science woven in—she is a good explainer, and has clearly made a notable effort to explain complex concepts in simple ways, while still delivering the complex concepts too (i.e. not overly “dumbing down”).
Bottom line: if you’d like to know about what can be done to increase your healthspan and general longevity, this book has a lot of answers!

The Subtle Art of Not Giving a F*ck – by Mark Manson
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.
You may wonder from the title: is this book arguing that we should all be callous heartless monsters? And no, it is not.
Instead, author Mark Manson advocates for cynicism, but less in the manner of Scrooge, and more in the manner of Diogenes:
- That life will involve struggle, so we might as well at least choose our struggles.
- That we will make mistakes, so we might as well accept them as learning experiences.
- That we will love and we will lose, so we might as well do it right while we can.
In short, the book is less about not caring… And more about caring about the right things only.
So, what are “the right things”? Manson bids us decide for ourselves, but certainly has ideas and pointers, with regard to what may or may not be healthy values to pursue.
The style throughout is casual and almost conversational, without being overly padded. It makes for very easy reading.
If the book has a weak point, it’s that when it briefly makes a suprisingly prescriptive turn into recommending we take up Buddhism, it may feel a bit like our friend who wants us to join in the latest MLM scheme. But, he’s soon back on track.
Bottom line: if you ever find yourself stressed with living up to unwanted expectations—your own, other people’s, and society’s—this book can really help streamline things.

Colloidal Gold’s Impressive Claims
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.
All That Glitters…
Today we’ll be examining colloidal gold supplementation.
This issue of 10almonds brought to you by the writer suddenly getting lots of advertisements for this supplement. It’s not a new thing though, and has been around in one form or another since pretty much forever.
Colloidal gold is…
- Gold, as in the yellow metal
- Colloidal, as in “very tiny insoluble particles dispersed though another substance (such as water)”
What are the claims made for it?
Honestly, just about everything is claimed for it. But to go with some popular claims:
- Reduces inflammation
- Supports skin health
- Boosts immune function
- Combats aging
- Improves cognitive function
So, what does the science say?
Does it do those things?
The short and oversimplified answer is: no
However, there is a little bit of tangential merit, so we’re going to talk about the science of it, and how the leap gets made between what the science says and what the advertisements say.
First… What makes gold so special, in general? Historically, three things:
- It’s quite rare
- It’s quite shiny
- It’s quite unreactive
- The first is about supply and demand, so that’s not very important to us in this article.
- The second is an aesthetic quality, which actually will have a little bit of relevance, but not much.
- The third has been important historically (because it meant that shiny gold stayed shiny, because it didn’t tarnish), and now also important industrially too, as gold can be used in many processes where we basically need for nothing to happen (i.e., a very inert component is needed)
That third quality—its unreactivity—has become important in medicine.
When scientists need a way to deliver something (without the delivering object getting eaten by the body’s “eat everything” tendencies), or otherwise not interact chemically with anything around, gold is an excellent choice.
Hence gold teeth, and gold fillings, by the way. They’re not just for the bling factor; they were developed because of their unreactivity and thus safety.
So, what about those health claims we mentioned above?
Here be science (creative interpretations not included)
The most-backed-by-science claim from that list is “reduces inflammation”.
Websites selling colloidal gold cite studies such as:
Gold nanoparticles reduce inflammation in cerebral microvessels of mice with sepsis
A promising title!The results of the study showed:
❝20 nm cit-AuNP treatment reduced leukocyte and platelet adhesion to cerebral blood vessels, prevented BBB failure, reduced TNF- concentration in brain, and ICAM-1 expression both in circulating polymorphonuclear (PMN) leukocytes and cerebral blood vessels of mice with sepsis. Furthermore, 20 nm cit-AuNP did not interfere with the antibiotic effect on the survival rate of mice with sepsis.❞
That “20 nm cit-AuNP” means “20 nm citrate-covered gold nanoparticles”
So it is not so much the antioxidant powers of gold being tested here, as the antioxidant powers of citrate, a known antioxidant. The gold was the carrying agent, whose mass and unreactivity allowed it to get where it needed to be.
The paper does say the words “Gold nanoparticles have been demonstrated to own important anti-inflammatory properties“ in the abstract, but does not elaborate on that, reference it, or indicate how.
Websites selling colloidal gold also cite papers such as:
Anti-inflammatory effect of gold nanoparticles supported on metal oxides
Another promising title! However the abstract mentions:
❝The effect was dependent on the MOx NPs chemical nature
[…]
The effect of Au/TiO2 NPs was not related to Au NPs size❞
MOx NPs = mineral oxide nanoparticles. In this case, the gold was a little more than a carrying agent, though, because the gold is described and explained as being a catalytic agent (i.e., its presence helps the attached mineral oxides react more quickly).
We said that was the most-backed claim, and as you can see, it has some basis but is rather tenuous since the gold by itself won’t do anything; it just helps the mineral oxides.
Next best-backed claim builds from that, which is “supports skin health”.
Sometimes colloidal gold is sold as a facial tonic. By itself it’ll distribute (inert) gold nanoparticles across your skin, and may “give you a healthy glow”, because that’s what happens when you put shiny wet stuff on your face.
Healthwise, if the facial tonic also contains some of the minerals we mentioned above, then it may have an antioxidant effect. But again, no minerals, no effect.
The claim that it “combats aging” is really a tag-on to the “antioxidant” claim.
As for the “supports immune health” claim… Websites selling colloid gold cite studies such as:
To keep things brief: gold can fight infectious diseases in much the same way that forks can fight hunger. It’s an inert carrying agent.
As for “improves cognitive function”? The only paper we could find cited was that mouse sepsis study again, this time with the website saying “researchers found that rats treated with colloidal gold showed improved spatial memory and learning ability“ whereas the paper cited absolutely did not claim that, not remotely, not even anything close to that. It wasn’t even rats, it was mice, and they did not test their memory or learning.
Is it safe?
Colloidal gold supplementation is considered very safe, precisely because gold is one of the least chemically reactive substances you could possibly consume. It is special precisely because it so rarely does anything.
However, impurities could be introduced in the production process, and the production process often involves incredibly harsh reagents to get the gold ions, and if any of those reagents are left in the solution, well, gold is safe but sodium borohydride and chloroauric acid aren’t!
Where can I get some?
In the unlikely event that our research review has given you an urge to try it, here’s an example product on Amazon
Take care!
