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:

Effect of Ganoderma lucidum capsules on T lymphocyte subsets in football players on “living high-training low”

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.❞

~ Yuen et al.

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:

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)

  • Be Your Future Self Now – by Dr. Benjamin Hardy

    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.

    Affirmations in the mirror are great and all, but they can only get you so far! And if you’re a regular reader of our newsletter, you probably know about the power of small daily habits adding up and compounding over time. So what does this book offer, that’s different?

    “Be Your Future Self Now” beelines the route “from here to there”, with a sound psychological approach. On which note…

    The book’s subtitle mentions “the science of intentional transformation”, and while Dr. Hardy is a psychologist, he’s an organizational psychologist (which doesn’t really pertain to this topic). It’s not a science-heavy book, but it is heavy on psychological rationality.

    Where Dr. Hardy does bring psychology to bear, it’s in large part that! He teaches us how to overcome our biases that cause us to stumble blindly into the future… rather than intentfully creating our own future to step into. For example:

    Most people (regardless of age!) acknowledge what a different person they were 10 years ago… but assume they’ll be basically the same person 10 years from now as they are today, just with changed circumstances.

    Radical acceptance of the inevitability of change is the first step to taking control of that change.

    That’s just one example, but there are many, and this is a book review not a book summary!

    In short: if you’d like to take much more conscious control of the direction your life will take, this is a book for you.

  • Edam vs Gouda – Which is Healthier?

    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.

    Our Verdict

    When comparing edam to gouda, we picked the edam.

    Why?

    There’s not a lot between them, but there are some differences:

    In terms of macros, their numbers are all close enough that one may beat the other by decimal place rounding, so we’ll call this a tie. Same goes for their fat type breakdowns; per 100g they both have 18g saturated, 8g monounsaturated, and 1g polyunsaturated.

    In the category of vitamins, edam has slightly more of vitamins A, B1, B2, and B3, while gouda has slightly more of vitamins B5 and B9. A modest 4:2 win for edam.

    When it comes to minerals, edam has more calcium, iron, and potassium, while gouda is not higher in any minerals. A more convincing win for edam.

    In short, enjoy either or both in moderation, but if you’re going to choose one over the other, edam is the way to go.

  • The Not-So-Sweet Science Of Sugar Addiction

    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.

    One Lump Mechanism Of Addiction Or Two?

    In Tuesday’s newsletter, we asked you to what extent, if any, you believe sugar is addictive; we got the above-depicted, below-described, set of responses:

    • About 47% said “Sugar is chemically addictive, comparable to alcohol”
    • About 34% said “Sugar is chemically addictive, comparable to cocaine”
    • About 11% said “Sugar is not addictive; that’s just excuse-finding hyperbole”
    • About 9% said “Sugar is a behavioral addiction, comparable to video gaming”

    So what does the science say?

    Sugar is not addictive; that’s just excuse-finding hyperbole: True or False?

    False, by broad scientific consensus. As ever, the devil’s in the details definitions, but while there is still discussion about how best to categorize the addiction, the scientific consensus as a whole is generally: sugar is addictive.

    That doesn’t mean scientists* are a hive mind, and so there will be some who disagree, but most papers these days are looking into the “hows” and “whys” and “whats” of sugar addiction, not the “whether”.

    *who are also, let us remember, a diverse group including chemists, neurobiologists, psychologists, social psychologists, and others, often collaborating in multidisciplinary teams, each with their own focus of research.

    Here’s what the Center of Alcohol and Substance Use Studies has to say, for example:

    Sugar Addiction: More Serious Than You Think

    Sugar is a chemical addiction, comparable to alcohol: True or False?

    True, broadly, with caveats—for this one, the crux lies in “comparable to”, because the neurology of the addiction is similar, even if many aspects of it chemically are not.

    In both cases, sugar triggers the release of dopamine while also (albeit for different chemical reasons) having a “downer” effect (sugar triggers the release of opioids as well as dopamine).

    Notably, the sociology and psychology of alcohol and sugar addictions are also similar (both addictions are common throughout different socioeconomic strata as a coping mechanism seeking an escape from emotional pain).

    See for example in the Journal of Psychoactive Drugs:

    Sweet Preference, Sugar Addiction and the Familial History of Alcohol Dependence: Shared Neural Pathways and Genes

    On the other hand, withdrawal symptoms from heavy long-term alcohol abuse can kill, while withdrawal symptoms from sugar are very much milder. So there’s also room to argue that they’re not comparable on those grounds.

    Sugar is a chemical addiction, comparable to cocaine: True or False?

    False, broadly. There are overlaps! For example, sugar drives impulsivity to seek more of the substance, and leads to changes in neurobiological brain function which alter emotional states and subsequent behaviours:

    The impact of sugar consumption on stress driven, emotional and addictive behaviors

    However!

    Cocaine triggers a release of dopamine (as does sugar), but cocaine also acts directly on our brain’s ability to remove dopamine, serotonin, and norepinephrine:

    The Neurobiology of Cocaine Addiction

    …meaning that in terms of comparability, they (to use a metaphor now, not meaning this literally) both give you a warm feeling, but sugar does it by turning up the heating a bit whereas cocaine does it by locking the doors and burning down the house. That’s quite a difference!

    Sugar is a behavioral addiction, comparable to video gaming: True or False?

    True, with the caveat that this a “yes and” situation.

    There are behavioral aspects of sugar addiction that can reasonably be compared to those of video gaming, e.g. compulsion loops, always the promise of more (without limiting factors such as overdosing), anxiety when the addictive element is not accessible for some reason, reduction of dopaminergic sensitivity leading to a craving for more, etc. Note that the last is mentioning a chemical but the mechanism itself is still behavioral, not chemical per se.

    So, yes, it’s a behavioral addiction [and also arguably chemical in the manners we’ve described earlier in this article].

    For science for this, we refer you back to:

    The impact of sugar consumption on stress driven, emotional and addictive behaviors

    Clarke’s focus here is on what she calls “stealthy healthy”, with the idea of dishes that feel indulgent while being great for the health.

    The recipes, of which there are well over 100, are indeed delicious and easy to make without being oversimplified, and since she encourages the use of in-season ingredients, many recipes come with a “market swaps” substitution guide, to make each recipe seasonal.

    The book is largely not vegetarian, let alone vegan, but the required substitutions will be second-nature to any seasoned vegetarian or vegan. Indeed, “skip the meat sometimes” is one of the advices she offers near the beginning of the book, in the category of tips to make things even healthier.

    Bottom line: if you want to add dishes to your repertoire that are great for entertaining and still super-healthy, this book will be a fine addition to your collection.

  • Artichoke vs Brussels Sprouts – Which is Healthier?

    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.

    Our Verdict

    When comparing artichoke to Brussels sprouts, we picked the sprouts.

    Why?

    Finally, a vegetable that beats artichoke—after it previously beat heart-of-palm, asparagus, and even cabbage! It was still close though, which is impressive for artichoke, considering what a nutritional powerhouse Brussels sprouts are:

    In terms of macros, the only meaningful difference is that artichoke has slightly more carbs and fiber, so artichoke gets the most marginal of nominal wins in this category.

    In the category of vitamins, however, artichoke has more of vitamins B3, B9, and choline, while Brussels sprouts have more of vitamins A, B1, B2, B6, C, E, and K, giving sprouts the clear victory here, especially with much higher margins of difference (e.g. 58x more vitamin A, as well as 7x more vitamin C, and 10x more vitamin K).

    When it comes to minerals, artichoke has more copper, magnesium, phosphorus, and zinc, while Brussels sprouts have more iron, manganese, potassium, and selenium, resulting in a 4:4 tie, and the small margins of difference are mostly comparable, with the exception that sprouts have 8x more selenium. So, Brussels sprouts win this category very marginally on that tie-breaker.

    Adding up the sections we see that macros and minerals gave a small win each to artichoke and sprouts respectively, while the vitamins category was an overwhelming win for sprouts, so—with this deciding factor in mind—sprouts win the day today.

  • Lobster vs Crab – Which is Healthier?

    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.

    Our Verdict

    When comparing lobster to crab, we picked the crab.

    Why?

    Generally speaking, most seafood is healthy in moderation (assuming it’s well-prepared, not poisonous, and you don’t have an allergy), and for most people, these two sea creatures are indeed considered a reasonable part of a healthy balanced diet.

    In terms of macros, they’re comparable in protein, and technically crab has about 2x the fat, but in both cases it’s next to nothing, so 2x almost nothing is still almost nothing. And, if we break down the lipids profiles, crab has a sufficiently smaller percentage of saturated fat (compared to monounsaturated and polyunsaturated), that crab actually has less saturated fat than lobster. In balance, the category of macros is either a tie or a slight win for crab, depending on your personal priorities.

    When it comes to vitamins, crab wins easily with more of vitamins A, B1, B2, B6, B9, B12, and C, in most cases by considerable margins (we’re talking multiples of what lobster has). Lobster, meanwhile, has more of vitamin B3 (tiny margin) and vitamin B5 (pantothenic acid, as in, the vitamin that’s in basically everything edible, and thus almost impossible to be deficient in unless literally starving).

    The minerals scene is more balanced; lobster has more calcium, copper, manganese, and selenium, while crab has more iron, magnesium, phosphorus, potassium, and zinc. The margins are comparable from one creature to another, so all in all the 4:5 score means a modest win for crab.

    Both of these creatures are good sources of omega-3 fatty acids, but crab is better.

    Lobster and crab are both somewhat high in cholesterol, but crab is the relatively lower of the two.

    In short: for most people most of the time, both are fine to enjoy in moderation, but if picking one, crab is the healthier by most metrics.
