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)

What the Most Successful People Do Before Breakfast – by Laura Vanderkram
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.
First, what this is not:this is not a rehash of “The 5AM Club”, and nor is it a rehash of “The Seven Habits of Highly Effective People”.
What it is: packed with tips about time management for real people operating here in the real world. The kind of people who have non-negotiable time-specific responsibilities, and frequent unavoidable interruptions. The kind of people who have partners, families, and personal goals and aspirations too.
The “two other short guides” mentioned in the subtitle are her other books, whose titles start the same but instead of “…before Breakfast”, substitute:
- …on the Weekend
- …at Work
However, if you’re retired (we know many of our subscribers are), this still applies to you:
- The “weekend” book is about getting the most out of one’s leisure time, and we hope you have that too!
- The “work” book is about not getting lost in the nitty-gritty of the daily grind, and instead making sure to keep track of the big picture. You probably have this in your personal projects, too!
Bottom line: if, in the mornings, it sometimes seems like your get-up-and-go has got up and gone without you, then you will surely benefit from this book that outstrips its competitors in usefulness and applicability.

Resistance Is Useful! (Especially As We Get Older)
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.
Resistance Is Useful!
At 10almonds we talk a lot about the importance of regular moderate exercise (e.g. walking, gardening, housework, etc), and with good reason: getting in those minutes (at least 150 minutes per week, so, a little over 20 minutes per day, or 25 minutes per day with one day off) is the exericise most consistently linked to better general health outcomes and reduced mortality risk.
We also often come back to mobility, because at the end of the day, being able to reach for something from a kitchen cabinet without doing oneself an injury is generally more important in life than being able to leg-press a car.
Today though, we’re going to talk about resistance training.
What is resistance training?
It can be weight-lifting, or it can be bodyweight exercises. In those cases, what you’re resisting is gravity. It can also be exercises with resistance bands or machines. In all cases, it’s about building and/or maintaining strength.
Why does it matter?
Let’s say you’re not an athlete, soldier, or laborer, and the heaviest thing you have to pick up is a bag of groceries. Strength still matters, for two main reasons:
- Muscle strength correlates to bone strength. You can’t build (or maintain) strong muscles on weak bones, so if you take care of your muscles, then your body will keep your bones strong too.
- That’s assuming you have a good diet as well—but today’s not about that. If you’d like to know more about eating for bone health though, do check out this previous article about that!
- Muscle strength correlates to balance and stability. You can’t keep yourself from falling over if you are physically frail.
Both of those things matter, because falls and fractures often have terrible health outcomes (e.g., slower recovery and more complications) the older we get. So, we want to:
- Ideally, not fall in the first place
- If we do fall, have robust bones
See also: Effects of Resistance Exercise on Bone Health
How much should we do?
Let’s go to the Journal of Strength and Conditioning Research on this one:
❝There is strong evidence to support the benefits of resistance exercise for countering many age-related processes of sarcopenia, muscle weakness, mobility loss, chronic disease, disability, and even premature mortality.
In addition, this Position Statement provides specific evidence-based practice recommendations to aid in the implementation of resistance exercise programs for healthy older adults and those with special considerations.
While there are instances where low-intensity, low-volume programs are appropriate (i.e., beginning programs for individuals with frailty or CVDs), the greatest benefits are possible with progression to moderate to higher intensity programs.❞
~ Fragala et al
Read the statement in full:
There’s a lot of science there and it’s well worth reading if you have the time. It’s particularly good at delineating how much is not enough vs how much is too much, and the extent to which we should (or shouldn’t) train to exhaustion.
If you don’t fancy that, though, and/or just want to start with something accessible and work your way up, the below is a very good (and also evidence-based) start-up plan:

It’s Q&A Day!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
This newsletter has been growing a lot lately, and so have the questions/requests, and we love that! 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
Q: I am now in the “aging” population. A great concern for me is Alzheimers. My father had it and I am so worried. What is the latest research on prevention?
Very important stuff! We wrote about this not long back:
(one good thing to note is that while Alzheimer’s has a genetic component, it doesn’t appear to be hereditary per se. Still, good to be on top of these things, and it’s never too early to start with preventive measures!)
Q: Foods that help build stronger bones and cut inflammation? Thank you!
We’ve got you…
For stronger bones / To cut inflammation
That “stronger bones” article is about the benefits of collagen supplementation for bones, but there’s definitely more to say on the topic of stronger bones, so we’ll do a main feature on it sometime soon!
Q: Veganism, staying mentally sharp, best exercises for weight gain?
All great stuff! Let’s do a run-down:
- Veganism? As a health and productivity newsletter, we’ll only be focusing veganism’s health considerations, but it does crop up from time to time! For example:
- Which Plant Milk? (entirely about such)
- Plant vs Animal Protein (mostly about such)
- Making Friends With Your Gut (You Can Thank Us Later) (discusses one benefit of such)
- Staying mentally sharp? You might like the things-against-dementia pieces we linked to in the previous response!
- It’s also worth noting that some kinds of dementia, such as Alzheimer’s, can begin the neurodegenerative process 20 years before symptoms show, and can be influenced by lifestyle choices 20 years before that, so it’s definitely never too early be on top of these things!
- Best exercises for weight gain? We’ll do a main feature one of these days (filled with good science and evidence), but in few words meanwhile: core exercises, large muscle groups, heavy weights, few reps, build up slowly. Squats are King.
Q: I am interested in the following: Aging, Exercise, Diet, Relationships, Purpose, Lowering Stress
You’re going to love our Psychology Sunday editions of 10almonds! You might like some of these…

Q: I’d like to know more about type 2 diabetic foot problems
You probably know that the “foot problems” thing has less to do with the feet and more to do with blood and nerves. So, why the feet?
The reason feet often get something like the worst of it, is because they are extremities, and in the case of blood sugars being too high for too long too often, they’re getting more damage as blood has to fight its way back up your body. Diabetic neuropathy happens when nerves are malnourished because the blood that should be keeping them healthy, is instead syrupy and sluggish.
We’ll definitely do a main feature sometime soon on keeping blood sugars healthy, for both types of diabetes plus pre-diabetes and just general advice for all.
In the meantime, here’s some very good advice on keeping your feet healthy in the context of diabetes. This one’s focussed on Type 1 Diabetes, but the advice goes for both:

Water’s Counterintruitive Properties

❝Why are we told to drink more water for everything, even if sometimes it seems like the last thing we need? Bloated? Drink water. Diarrhea? Drink water. Nose running like a tap? Drink water❞
While water will not fix every ill, it can fix a lot, or at least stop it from being worse!
Our bodies are famously over 60% water (exact figure will depend on how well-hydrated you are, obviously, as well as your body composition in terms of muscle and fat). Our cells (which are mostly full of mostly water) need replacing all the time, and almost everything that needs transporting almost anywhere is taken there by blood (which is also mostly water). And if we need something moving out of the body? Water is usually going to be a large part of how it gets ejected.
In the cases of the examples you gave…
- Bloating: bloating is often a matter of water retention, which often happens as a result of having too much salt, and/or sometimes too much fat. So the body’s homeostatic system (the system that tries to maintain all kinds of equilibrium, keeping salt balance, temperature, pH, and many other things in their respective “Goldilocks zones”) tries to add more water to where it’s needed to balance out the salt etc.
- Consequently, drinking more water means the body will note “ok, balance restored, no need to keep retaining water there, excess salts being safely removed using all this lovely water”.
- Diarrhea: this is usually a case of a bacterial infection, though there can be other causes. Whether for that reason or another, the body has decided that it needs to give your gut an absolute wash-out, and it can only do that from the inside—so it uses as much of the body’s water as it needs to do that.
- Consequently, drinking more water means that you are replenishing the water that the body has already 100% committed to using. If you don’t drink water, you’ll still have diarrhea, you’ll just start to get dangerously dehydrated.
- Runny nose: this is usually a case of either fighting a genuine infection, or else fighting something mistaken for a pathogen (e.g. pollen, or some other allergen). The mucus is an important part of the body’s defense: it traps the microbes (be they bacteria, virus, whatever) and water-slides them out of the body.
- Consequently, drinking more water means the body can keep the water-slide going. Otherwise, you’ll just get gradually more dehydrated (because as with diarrhea, your body will prioritize this function over maintaining water reserves—water reserves are there to be used if necessary, is the body’s philosophy) and if the well runs dry, you’ll just be dehydrated and have a higher pathogen-count still in your body.

Escape Self-Sabotage

Stop Making The Same Mistakes
It’s easy to think that a self-destructive cycle is easy to avoid if you have no special will to self-destruction. However, the cycle is sneaky.
It’s sneaky because it can be passive, and/or omissions rather than actions, procrastinations rather than obvious acts of impulse, and so forth.
So, they’re often things that specifically aren’t there to see.
How to catch them
How often do you think “I wish I had [done xyz]” or “I wish I had [done yxz] sooner”?
Now, how often have you thought that about the same thing more than once? For example, “I should have kept up my exercise”.
For things like this, habit-trackers are a great way to, well, keep track of habits. If for example you planned to do a 10-minute exercise session daily but you’ve been postponing it since you got distracted on January the 2nd, then it’ll highlight that. See also:
How To Really Pick Up (And Keep!) Those Habits
Speaking of habits, this goes for other forms of procrastination, too. For example, if you are always slow to get medical check-ups, or renew your prescriptions, or get ready for some regularly-occurring thing in your schedule, then set a reminder in your preferred way (phone app, calendar on the wall, whatever) and when the appointed time arrives (to book the check-up, renew the prescription, do your taxes, whatever), do it on the day you set your reminder for, as a personal rule for you that you keep to, barring extreme calamity.
By “extreme calamity” we mean less “running late today” and more “house burned down”.
Digital traps
Bad habits can be insidious in other ways too, like getting sucked into social media scrolling (it is literally designed to do that to you; you are not immune modern programming hijacking evolutionary dopamine responses).
Setting a screentime limit (you can specify “just these apps” if you like) will help with this. On most devices, this feature includes a sticky notification in the notification bar, that’ll remind you “27 out of 30 minutes remaining” or whatever you set it for. That’ll remind you to do what you went there to do, instead of getting caught in the endless scroll (and if you went there to just browse, to do so briefly).
Here’s how to set that:
Instructions for iOS devices | Instructions for Android devices
Oh, and on the topic of social media? If you find yourself getting caught up in unproductive arguments on the Internet, try the three-response rule:
- You reply; they reply (no progress made)
- You reply; they reply (still no progress made)
- You reply; they reply (still yet no progress made)
You reply just one more time: “I have a personal rule that if I’m arguing on the Internet and no progress has been made after three replies, I don’t reply further—I find this is helpful to avoid a lot of time lost to pointless arguing that isn’t going anywhere. Best wishes.”
(and then stick to it, no matter how they try to provoke you; best is to just not look until at least the next day)
When “swept up in love” gets to one of those little whirlpools…
The same works in personal relationships, by the way. If for example you are arguing with a loved one and not making progress, it can be good if you both have a pre-arranged agreement that either of you can, up to once on any given day, invoke a “time-out” (e.g. 30 minutes, but you agree the time between you when you first make this standing policy) during which you will both keep out of the other’s way, and come back with a more productive head on (remembering that things go best when it’s you both vs the problem, rather than vs each other).

Seriously Useful Communication Skills: Conflict Resolution
What if the self-sabotaging cycle is active and apparent?
Well, that is less sneaky, but certainly no less serious, and sometimes moreso. An obvious example is drinking too much; this is often cyclical in nature. We wrote about this one previously:
That article’s alcohol-specific, but the same advices go for other harmful activities, including other substance abuse (which in turn includes binge-eating), as well psychological addictions (such as gambling, for example).
Finally…
If your destructive cycle is more of a rut you’ve got stuck in, a common advice is to change something, anything, to get out of the rut.
That can be very bad advice! Because sometimes the change you go for is absolutely not the change that was needed, and is rather just cracking under pressure and doing something impulsive.
Here’s one way to actively get out of a slump:
Behavioral Activation Against Depression & Anxiety
Note: you do not have to be depressed or anxious to do this. But the point is, it’s a tool you can use even if you are depressed and/or anxious, so it’s a good thing to try for getting out of most kinds of slumps.
And really finally, here’s a resource for, well, the title speaks for itself:

Superfood Kale & Dill Pâté
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.
Most of us could do with eating more greens a lot of the time, but it’s not always easy to include them. This kale and dill pâté brings a healthy dose of green in luxurious style, along with abundant phytochemicals and more!
You will need
- 2 handfuls kale, stalks removed
- 1 cup soft cheese (you can use our Healthy Plant-Based Cream Cheese recipe if you like)
- 2 tbsp fresh dill, chopped
- 1 tsp capers
- 1 tsp black pepper, coarse ground
- ½ tsp MSG, or 1 tsp low-sodium salt
Method
(we suggest you read everything at least once before doing anything)
1) Steam the kale for about 5 minutes or until wilted and soft. Run under cold water to halt the cooking process.
2) Combine all the ingredients, including the kale you just blanched, in a food processor and blitz to make a smooth pâté.
3) Serve with oatcakes or vegetable sticks, or keep in the fridge to enjoy it later:
Enjoy!
