The Immunostimulant Superfood –

First, what this book is not: a “detox cleanse” book of the kind that claims you can flush out the autism if you just eat enough celery.
What it rather is: an overview brain chemistry, gut microbiota, and the very many other bodily systems that interact with these “two brains”.
She also does some mythbusting of popular misconceptions (for example with regard to tryptophan), and explains with good science just what exactly such substances as gluten and casein can and can’t do.
The format is less of a textbook and more a multipart (i.e., chapter-by-chapter) lecture, in pop-science style though, making it very readable. There are a lot of practical advices too, and options to look up foods by effect, and what to eat for/against assorted mental states.
Bottom line: anyone who eats food is, effectively, drugging themselves in one fashion or another—so you might as well make a conscious choice about how to do so.

The Cold Truth About Respiratory Infections
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 Pathogens That Came In From The Cold
Yesterday, we asked you about your climate-themed policy for avoiding respiratory infections, and got the above-depicted, below-described, set of answers:
- About 46% of respondents said “Temperature has no bearing on infection risk”
- About 31% of respondents said “It’s important to get plenty of cold, fresh air, as this kills/inactivates pathogens”
- About 22% of respondents said “It’s important to stay warm to avoid getting colds, flu, etc”
Some gave rationales, including…
For “stay warm”:
❝Childhood lessons❞
For “get cold, fresh air”:
❝I just feel that it’s healthy to get fresh air daily. Whether it kills germs, I don’t know❞
For “temperature has no bearing”:
❝If climate issue affected respiratory infections, would people in the tropics suffer more than those in colder climates? Pollutants may affect respiratory infections, but I doubt just temperature would do so.❞
So, what does the science say?
It’s important to stay warm to avoid getting colds, flu, etc: True or False?
False, simply. Cold weather does increase the infection risk, but for reasons that a hat and scarf won’t protect you from. More on this later, but for now, let’s lay to rest the idea that bodily chilling will promote infection by cold, flu, etc.
In a small-ish but statistically significant study (n=180), it was found that…
❝There was no evidence that chilling caused any acute change in symptom scores❞
Read more: Acute cooling of the feet and the onset of common cold symptoms
Note: they do mention in their conclusion that chilling the feet “causes the onset of cold symptoms in about 10% of subjects who are chilled”, but the data does not support that conclusion, and the only clear indicator is that people who are more prone to colds generally, were more prone to getting a cold after a cold water footbath.
In other words, people who were more prone to colds remained more prone to colds, just the same.
It’s important to get plenty of cold, fresh air, as this kills/inactivates pathogens: True or False?
Broadly False, though most pathogens do have an optimal operating temperature that (for obvious reasons) is around normal human body temperature.
However, given that they don’t generally have to survive outside of a host body for long to get passed on, the fact that the pathogens may be a little sluggish in the great outdoors will not change the fact that they will be delighted by the climate in your respiratory tract as soon as you get back into the warm.
With regard to the cold air not being a reliable killer/inactivator of pathogens, we call to the witness stand…
Polar Bear Dies From Bird Flu As H5N1 Spreads Across Globe
(it was found near Utqiagvik, one of the northernmost communities in Alaska)
Because pathogens like human body temperature, raising the body temperature is a way to kill/inactivate them: True or False?
True! Unfortunately, it’s also a way to kill us. Because we, too, cannot survive for long above our normal body temperature.
So, for example, bundling up warmly and cranking up the heating won’t necessarily help, because:
- if the temperature is comfortable for you, it’s comfortable for the pathogen
- if the temperature is dangerous to the pathogen, it’s dangerous to you too
This is why the fever response evolved, and/but why many people with fevers die anyway. It’s the body’s way of playing chicken with the pathogen, challenging “guess which of us can survive this for longer!”
Temperature has no bearing on infection risk: True or False?
True and/or False, circumstantially. This one’s a little complex, but let’s break it down to the essentials.
- Temperature has no direct effect, for the reasons we outlined above
- Temperature is often related to humidity, which does have an effect
- Temperature does tend to influence human behavior (more time spent in open spaces with good ventilation vs more time spent in closed quarters with poor ventilation and/or recycled air), which has an obvious effect on transmission rates
The first one we covered, and the third one is self-evident, so let’s look at the second one:
Temperature is often related to humidity, which does have an effect
When the environmental temperature is warmer, water droplets in the air will tend to be bigger, and thus drop to the ground much more quickly.
When the environmental temperature is colder, water droplets in the air will tend to be smaller, and thus stay in the air for longer (along with any pathogens those water droplets may be carrying).
Some papers on the impact of this:
- Cold temperature and low humidity are associated with increased occurrence of respiratory tract infections
- A Decrease in Temperature and Humidity Precedes Human Rhinovirus Infections in a Cold Climate
So whatever temperature you like to keep your environment, humidity is a protective factor against respiratory infections, and dry air is a risk factor.
So, for example:
- If the weather doesn’t suit having good ventilation, a humidifier is a good option
- Being in an airplane is one of the worst places to be for this, outside of a hospital
Don’t have a humidifier? Here’s an example product on Amazon, but by all means shop around.
A crock pot with hot water in and the lid off is also a very workable workaround too
Take care!

The Purple Parsnip’s Bioactive Brain Benefits (& 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.
This Root Might Be A Guardian Angel
Sometimes we go searching for supplements to research; sometimes supplements present themselves for examination! In this case, our attention was grabbed by a headline:
Angelica gigas extract emerges as a potential treatment for vascular disease
Angelica who?
Angelica gigas, also called the purple parsnip (amongst other names), is a flowering plant native to Korea. It has assorted medicinal properties, and in this case, it was its heart-healthy benefits that were making news:
❝Ultimately, this study presents clearly evidence that Angelica gigas extract is a promising natural product-based functional food/herbal medicine candidate for preventing or regulating hyperlipidemic cardiovascular complications❞
But it has a lot more to offer…
The root has various bioactive metabolites, but the compounds that most studies are most interested in are decursin and decursinol, for their neuroprotective and cognitive enhancement effects:
❝[C]rude extracts and isolated components from the root of A. gigas exhibited neuroprotective and cognitive enhancement effects.
Neuronal damage or death is the most important factor for many neurodegenerative diseases.
In addition, recent studies have clearly demonstrated the possible mechanisms behind the neuroprotective action of extracts/compounds from the root of A. gigas.❞
That middle paragraph there? That’s one of the main pathogenic processes of Alzheimer’s, Parkinson’s, Huntington’s, and Multiple Sclerosis.
Angelica gigas attenuates (reduces the force of) that process:
❝The published reports revealed that the extracts and isolated components from the root of A. gigas showed neuroprotective and cognitive enhancement properties through various mechanisms such as anti-apoptosis, antioxidative actions, inhibiting mRNA and protein expressions of inflammatory mediators and regulating a number of signaling pathways.
In conclusion, the A. gigas root can serve as an effective neuroprotective agent by modulating various pathophysiological processes❞
Read more: Neuroprotective and Cognitive Enhancement Potentials of Angelica gigas Nakai Root: A Review
Beyond neuroprotection & cognitive enhancement
…and also beyond its protection against vascular disease, which is what got our attention…
Angelica gigas also has antioxidant properties, anti-cancer properties, and general immune-boosting properties.
We’ve only so much room, so: those links above will take you to example studies for those things, but there are plenty more where they came from, so we’re quite confident in this one.
Of course, what has antioxidant properties is usually anti-inflammatory, anti-cancer, and anti-aging, because these things are reliant on many of the same processes as each other, with a lot of overlap.
Where can we get it?
We don’t sell it, but here’s an example product on Amazon, for your convenience
Enjoy!

The Keys to Good Mental Wellbeing
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 Nine Keys To Good Mental Wellbeing
Today’s main feature is a bit “pop psychology”, but it has its underpinnings in actual psychology, and is especially useful if approached from that angle.
What it’s most popularly enjoyed as:
- A personality-typing system.
- People love little quizzes and identifiers and such.
What it’s actually really useful as:
- A tool for understanding why people (including ourselves) are the way we are
- A foundational knowledge for living better ourselves, and helping others too
This stems from the fairly simple principle, uncontroversial in psychology:
- We have needs, desires, and aversions
- We act in a way that tries to get our needs met and avoid suffering
- Thus: Need/Fear → Motivation → Action
The Enneagram
The Enneagram (ἐννέα = “nine” in Ancient Greek) system posits that we each have one fundamental need/fear (from a list of nine) that’s strongest for us. A deep-seated insecurity/longing, that we’ll go to almost any lengths to try to meet. Sometimes, in good ways, sometimes, bad.
The Nine Basic Fears/Insecurities, And Their Corresponding Needs/Desires:
- Fear of being a fundamentally bad, wrong person / Need to be good and correct
- Fear of being fundamentally unloveable / Need to be loved
- Fear of being fundamentally worthless / Need to be valued
- Fear of being like everyone else / Need to be different
- Fear of being useless / Need to be useful
- Fear of being outcast / Need to have a set place in the group
- Fear of missing out / Need to experience things
- Fear of being hurt or controlled / Need to be in control
- Fear of conflict / Need to be at peace
Of course, most of us have most of these fears/needs to some extent, though usually one will stand out—especially if we aren’t managing it well. The less healthy our coping mechanisms, the more obvious it is how we’re trying to overcompensate in some fashion. For example:
- A person who fears being wrong and so becomes a perfectionist rules-abider to a fault
- A person who fears being unloveable, and so exaggerates problems to get pity, as the next best thing
- A person who fears being worthless, and so exaggerates their accomplishments in order to be admired and valued
- A person who fears being like everyone else, and so descends into a “nobody could ever possibly understand me” black hole of pathos.
- A person who fears being useless, so burns themself out trying to be an omnicompetent Leonardo da Vinci without ever actually taking the time to stop and smell the flowers as Leonardo did.
- A person who fears being outcast, so becomes clingy, passive-aggressive, and suspicious
- A person who fears missing out, so tries to experience all the things all the time, ruining their health with dizzying highs and crushing lows.
- A person who fears being hurt or controlled, so becomes aggressive and domineering
- A person who fears conflict, so shuts down at the slightest hint of it
If we have healthier coping mechanisms, these same nine people can look a lot different, but in much more subtle ways because we’re not trying to overcompensate so badly:
- A person who lives their life rationally by principles that can be adapted as they learn
- A person who loves and is loved, as perhaps the most notable part of their character
- A person who sets reasonable goals and accomplishes them, and seeks to uplift others
- A person who creates and innovates, enriching their own life and the lives of others
- A person who is simply very competent and knowledgeable, without overstretching
- A person who is dependable and loyal, and a reliable part of something bigger than themself
- A person who is fun to be around and loves trying new things, while also knowing how to relax
- A person who develops their leadership skills and is a tower of strength for others
- A person who knows how to make peace and does so—by themself, and with others
By being aware of our own fears/insecurities that may drive our motivations and thus underpin our behaviors, we can usually manage them in a much more mindful fashion. Same goes when it comes to managing interactions with other people, too:
- Letting the Type 3 know you value them, not their accomplishments or what they can do for you.
- Appreciating the Type 5’s (varied or specialist) skills and knowledge.
- Giving love to a Type 2 unprompted, but on your own terms, with your own boundaries.
- And so on for other types
Or for yourself…
- As a Type 8, remembering that you can let go sometimes and let someone else be in charge.
- As a Type 1, catching yourself holding yourself (or others) to impossible standards, and then easing up on that a little.
- As a Type 9, remembering to stand up for yourself and others, however gently, but firmly.
- And so on for other types
If you’re unsure what to focus on, ask yourself: what’s your worst nightmare or greatest daydream? Then work out what it is about that, that makes it feel so bad or good.
Then, approach things mindfully. Catch yourself in your unhealthy coping mechanisms, and find healthy ones instead.
What if I get my type wrong? Or I get someone else’s type wrong?
Obviously it’s better to get them right for maximum effect, but you can never go too far wrong anyway… because we all have all nine of those qualities in us, it’s just a matter of how strong a factor each is for us. So in the worst case scenario, you’ll make someone feel more secure about something that was only a very minor insecurity for them, for example.
Or in the case of your own type, you may mistakenly think you’re acing being the world’s healthiest Type 5, until you realize you’re actually a Type 3 who thought learning all those things would make you more worthy (spoiler: those things are great, but you’re worthy already). Again, not the end of the world! No matter what, you’re learning and growing, and that’s good.
Want to delve further?
Read: The Nine Enneagram Type Descriptions (Basic, but more detailed descriptions than the above)
Read: How The Enneagram System Works (More complex. Now we’re getting into the more arcane stuff we didn’t have time for today—wings and lines, triads, health levels, directions of integration and disintegration, and more)
Like learning from books? Here are our top two picks, depending on your learning style:
- The Wisdom of the Enneagram – Very comprehensive textbook and guide to improving your coping mechanism and growing as a person.
- The Enneagram Made Easy – it explains it with cartoons!
We’d love to offer a quick free test here, but all the tests we could find either require paid registration or are wildly inaccurate, so we’ll not waste your time.
However, we do also think that working it out for yourself is better, as it means you have a handle on what those ideas, fears, insecurities, desires, needs, really mean to you—that way you can actually use the information!
We’ll close by repeating our previous advice: If you’re unsure what to focus on, ask yourself: what’s your worst nightmare or greatest daydream? Then work out what it is about those scenarios that make them so bad or good. That’ll help you find your real fears/needs, such that you can work on them.
Good luck!

You Are the One You’ve Been Waiting For – by Dr. Richard Schwartz
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.
As self-therapy approaches go, the title here could be read two ways: as pop-psychology fluff, or a suggestion of something deeper. And, while written in a way to make it accessible to all, we’re happy to report the content consists of serious therapeutic ideas, presented clearly.
Internal Family Systems (IFS) is a large, internationally recognized, and popular therapeutic approach. It’s also an approach that lends itself quite well to self-therapy, as this book illustrates.
Dr. Schwartz kicks off by explaining not IFS, but the problem that it solves… We (most of us, anyway) have over the course of our lives tried to plug the gaps in our own unmet psychological needs. And, that can cause resentment, strain, and can even be taken out on others if we’re not careful.
The real meat of the book, however, is in its illustrative explanations of how IFS works, and can be applied by an individual. The goal is to recognize all the parts that make us who we are, understand what they need in order to be at peace, and give them that. Spoiler: most what they will need is just being adequately heard, rather than locked in a box untended.
One of the benefits of using this book for self-therapy, of course, is that it requires a lot less vulnerability with a third party.
But, speaking of which, what of these intimate relationships the subtitle of the book referenced? Mostly the benefits to such come from a “put your own oxygen mask on first” angle… but the book does also cover discussions between intimate partners, and approaches to love, including what the author calls “courageous love”.
Bottom line: this is a great book if you want to do some “spring-cleaning of the soul” and live a little more lightly as a result.

How Much Can Hypnotherapy Really Do?
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.
Sit Back, Relax, And…
In Tuesday’s newsletter, we asked you for your opinions of hypnotherapy, and got the above-depicted, below-described, set of responses:
- About 58% said “It is a good, evidenced-based practice that can help alleviate many conditions”
- Exactly 25% said “It is a scam and sham and/or wishful thinking at best, and should be avoided by all”
- About 13% said “It works only for those who are particularly suggestible—but it does work for them”
- One (1) person said “It is useful only for brain-centric conditions e.g. addictions, anxiety, phobias, etc”
So what does the science say?
Hypnotherapy is all in the patient’s head: True or False?
True! But guess which part of your body controls much of the rest of it.
So while hypnotherapy may be “all in the head”, its effects are not.
Since placebo effect, nocebo effect, and psychosomatic effect in general are well-documented, it’s quite safe to say at the very least that hypnotherapy thus “may be useful”.
Which prompts the question…
Hypnotherapy is just placebo: True or False?
False, probably. At the very least, if it’s placebo, it’s an unusually effective placebo.
And yes, even though testing against placebo is considered a good method of doing randomized controlled trials, some placebos are definitely better than others. If a placebo starts giving results much better than other placebos, is it still a placebo? Possibly a philosophical question whose answer may be rooted in semantics, but happily we do have a more useful answer…
Here’s an interesting paper which: a) begins its abstract with the strong, unequivocal statement “Hypnosis has proven clinical utility”, and b) goes on to examine the changes in neural activity during hypnosis:
Brain Activity and Functional Connectivity Associated with Hypnosis
It works only for the very suggestible: True or False?
False, broadly. As with any medical and/or therapeutic procedure, a patient’s expectations can affect the treatment outcome.
And, especially worthy of note, a patient’s level of engagement will vastly affect it treatment that has patient involvement. So for example, if a doctor prescribes a patient pills, which the patient does not think will work, so the patient takes them intermittently, because they’re slow to get the prescription refilled, etc, then surprise, the pills won’t get as good results (since they’re often not being taken).
How this plays out in hypnotherapy: because hypnotherapy is a guided process, part of its efficacy relies on the patient following instructions. If the hypnotherapist guides the patient’s mind, and internally the patient is just going “nope nope nope, what a lot of rubbish” then of course it will not work, just like if you ask for directions in the street and then ignore them, you won’t get to where you want to be.
For those who didn’t click on the above link by the way, you might want to go back and have a look at it, because it included groups of individuals with “high/low hypnotizability” per several ways of scoring such.
It works only for brain-centric things, e.g. addictions, anxieties, phobias, etc: True or False?
False—but it is better at those. Here for example is the UK’s Royal College of Psychiatrists’ information page, and if you go to “What conditions can hypnotherapy help to treat”, you’ll see two broad categories; the first is almost entirely brain-stuff; the second is more varied, and includes pain relief of various kinds, burn care, cancer treatment side effects, and even menopause symptoms. Finally, warts and other various skin conditions get their own (positive) mention, per “this is possible through the positive effects hypnosis has on the immune system”:

You, Happier – by Dr. Daniel Amen
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 implicit question “what’s your brain type?” makes this book sound a little like a horoscope for science-enjoyers, but really, the “brain type” in question is simply a way of expressing which neurochemicals one’s brain makes most and/or least easily.
That’s something that a) really does differ from one person to another b) isn’t necessarily fixed forever, but will tend to remain mostly the same most of the time for most people.
And yes, the book does cover figuring out which neurotransmitter(s) it might be for you. On a secondary level, it also talks about more/less active parts of the brain for each of us, but the primary focus is on neurotransmitters.
It’s easy to assume “everyone wants more [your favorite neurotransmitter here]” but in fact, most people most of the time have most of what they need.
For those of us who don’t, those of us who perhaps have to work more to keep our level(s) of one or more neurotransmitters where they should be, this book is a great guide to optimizing aspects of our diet and lifestyle to compensate for what our brains might lack—potentially reducing the need to go for pharmaceutical approaches.
The style of the book is very much pop-science, but it is all well-informed and well-referenced.
Bottom line: if you sometimes (or often!) think “if only my brain would just make/acknowledge more [neurotransmitter], this book is for you.
Click here to check out You, Happier, and discover a happier you!
