Do you ever find that your feelings (or occasionally: lack thereof) sometimes can seem mismatched with the observed facts of your situation? This book unravels that mystery—or rather, that stack of mysteries.
Dr. Porges’ work on this topic is, by the way, the culmination of 40 years of research. While he’s not exactly a household name to the layperson, he’s very respected in his field, and this book is his magnum opus.
Here he explains the disparate roles of the two branches of the vagus nerve (hence: polyvagal theory). At least, the two branches that we mammals have; non-mammalian vertebrates have only one. This makes a big difference, because of the cascade of inhibitions that this allows.
The answer to the very general question “What stops you from…?” is usually found somewhere down this line of cascade of inhibitions.
These range from “what stops you from quitting your job/relationship/etc” to “what stops you from freaking out” to “what stops you from relaxing” to “what stops you from reacting quickly” to “what stop you from giving up” to “what stops you from gnawing your arm off” and many many more.
And because sometimes we wish we could do something that we can’t, or wish we wouldn’t do something that we do, understanding this process can be something of a cheat code to life.
A quick note on style: the book is quite dense and can be quite technical, but should be comprehensible to any layperson who is content to take their time, because everything is explained as we go along.
Bottom line: if you’d like to better understand the mysteries of how you feel vs how you actually are, and what that means for what you can or cannot wilfully do, this is a top-tier book

9 Reasons To Avoid Mobility Training
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.
Why might someone not want to do mobility training? Here are some important reasons:
Make an informed choice
Here’s Liv’s hit-list of reasons to skip mobility training:
- Poor Circulation: Avoid mobility training if you don’t want to improve or maintain good blood circulation, which aids muscle recovery and reduces soreness.
- Low Energy Levels: Mobility training increases oxygen flow to the brain and muscles, boosting energy. Skip it if you prefer feeling sluggish!
- Digestive Health: Stretches that rotate the torso aid digestion and relieve bloating. Definitely best to avoid it if you’re uninterested in improving digestive health.
- Joint Health: Mobility work stimulates synovial fluid production, reducing joint friction and promoting longevity. You can skip it if you don’t care about comfortable movement.
- Sleep Quality: Gentle stretching triggers relaxation, aiding restful sleep. Avoid it if you enjoy restless nights!
- Pain Tolerance: Stretching trains the nervous system to handle discomfort better. Skip it if you prefer suffering 🙂
- Headache Reduction: Mobility work relieves tension in the neck and shoulders, reducing the occurrence and severity of headaches. No need to do it if you’re fine with frequent headaches.
- Immune System Support: Mobility training boosts lymphatic circulation, aiding the immune system. Avoid it if you prefer your immune system to get exciting in a bad way.
- Stress Reduction: Mobility exercises release endorphins and lower cortisol levels, reducing stress. So, it is certainly best to skip it if you prefer feeling stressed and enjoy the many harmful symptoms of high cortisol levels!

The Immunostimulant Superfood

Eat These Greens!
Chlorella vulgaris, henceforth “chlorella”, is a simple green algae that has a lot of health benefits.
Note: most of the studies here are for Chlorella vulgaris specifically. However, some are for other species of the Chlorella genus, of which Chlorella vulgaris is by far the most common, hence the name (vulgaris = common). The relevant phytochemical properties appear to be the same regardless.
Superfood
While people generally take it as a supplement rather than a food item in any kind of bulk, it is more than 50% protein and contains all 9 essential amino acids.
As you might expect of a green superfood, it’s also full of many antioxidants, most of them carotenoids, and these pack a punch, for example against cancer:
It also has a lot of vitamins and minerals, and even omega-3.
Which latter also means it helps improve lipids and is thus particularly…
Heart healthy
❝Daily consumption of Chlorella supplements provided the potential of health benefits reducing serum lipid risk factors, mainly triglycerides and total cholesterol❞
Its heart-healthy benefits don’t stop at lipids though, and include blood pressure management, as in this study that found…
❝GABA-rich Chlorella significantly decreased high-normal blood pressure and borderline hypertension, and is a beneficial dietary supplement for prevention of the development of hypertension. ❞
About that GABA, if you’re curious about that, check out:
GABA Against Stress, Anxiety, & More
May remove heavy metals
We’re going with “may” for this one as we could only find animal studies so far (probably because most humans don’t have megadoses of heavy metals in them, which makes testing harder).
Here’s an example animal study, though:
Enhanced elimination of tissue methyl mercury in [Chlorella]-fed mice
Immunostimulant
This one’s clearer, for example in this 8-week study (with humans) that found…
❝Serum concentrations of interferon-γ (p<0.05) and interleukin-1β (p<0.001) significantly increased and that of interleukin-12 (p<0.1) tended to increase in the Chlorella group.
The increments of these cytokines after the intervention were significantly bigger in the Chlorella group than those in the placebo group. In addition, NK cell activities (%) were significantly increased in Chlorella group, but not in Placebo group.
The increments of NK cell activities (%) were also significantly bigger in the Chlorella group than the placebo group.
Additionally, changed levels of NK cell activity were positively correlated with those of serum interleukin-1β (r=0.280, p=0.047) and interferon-γ (r=0.271, p<0.005).❞
tl;dr = it boosts numerous different kinds of immune cells
PS, if you click though to the study, you may be momentarily alarmed by the first paragraph of the abstract that says “However, there were no direct evidences for the effect of Chlorella supplementation on immune/inflammation response in healthy humans“
this is from the “Background” section of the abstract, so what they are saying is “before we did this study, nobody had done this yet”.
So, be assured that the results are worthwhile and compelling.
Is it safe?
Based on the studies, it has a good safety profile. However, as it boosts the immune system, you may want to check with your doctor if you have an autoimmune disorder, and/or you are on immunosuppressants.
And in general, of course always check with your doctor/pharmacist if unsure about any potential drug interactions.

The Off-Button For Your Brain
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 Off-Button For Your Brain
We evolved our emotions for our own benefit as a species. Even the “negative” ones:
- Stress keeps us safe by making sure we take important situations seriously
- Anger keeps us safe by protecting us from threats
- Disgust keeps us safe by helping us to avoid things that might cause disease
- Anxiety keeps us safe by ensuring we don’t get complacent
- Guilt keeps us safe by ensuring we can function as a community
- Sadness keeps us safe by ensuring we value things that are important to us, and learn to become averse to losing them
- …and so on
But that’s not always useful. What was once a very good response to a common source of fear (for example, a sabre-toothed tiger) is no longer a helpful response to a modern source of fear (for example, an important interview).
Sometimes it’s good to take the time and energy to process our feelings and the event(s) that prompted those feelings. Sometimes, we don’t have that luxury.
For example, if you are stressed about your workload? Then staying awake half the night thinking about it is only going to make your problems worse the next day.
So, how to switch that off, or at least put a pause on it?
The human mind tends to have a “negative bias”, evolved for our own protection. If something is “good enough”, we don’t need to worry about it, so we move on to the next thing, until we find something that is a problem, then we dwell on that. That’s not always helpful, and the good news is, there’s a way to flip the switch on this process:
Identifying the positive, and releasing the rest
This exercise can be done when you’re trying to sleep, or at any time you need a calmer, quieter mind.
Take a moment to notice whatever you’re experiencing.
If it’s something that feels good, or neutral, identify it with a single word. For example:
- Warmth
- Soft
- Security
- Smile
- Peace
If it’s something that feels bad, then instead of identifying it, simply say (or think) to yourself “release”.
You can’t fight bad feelings with force, and you can’t “just not think about them”, but you can dismiss them as soon as they arrive and move onto the next thing. So where your train of thought may previously have been:
It’s good to be in bed ➔ I have eight hours to sleep before my meeting ➔ Have I done everything I was supposed to? ➔ I hope that what I’ve done is good enough ➔ [Mentally rehearsing how the meeting might go] ➔ [various disaster preparations] ➔ What am I even going to wear? ➔ Ugh I forgot to do the laundry ➔ That reminds the electricity bill is due ➔ Etc
Now your train of thought may be more like:
Relief ➔ Rest ➔ But my meeti—release ➔ If I—release ➔ soft ➔ comfort ➔ release ➔ pillow ➔ smile ➔ release ➔ [and before you know it you’re asleep]
And if you do this in a situation where you’re not going to sleep? Same process, just a more wakeful result, for example, let’s move the scene to an office where your meeting will shortly take place:
Five minutes to go ➔ What a day ➔ Ok, I’d better clear my head a bit ➔ release ➔ release ➔ breath ➔ light ➔ chair ➔ what if—release ➔ prepared ➔ ready ➔ calm ➔ [and before you know it you’re impressing your work associate with your calm preparedness]
In summary:
If you need to stop a train of thought, this method may help. Especially if you’re in a situation where you can’t use some external distraction to keep you from thinking about the bad thing!
You’re probably still going to have to deal with the Bad Thing™ at some point—you’ve just recognized that now isn’t the time for that. Mentally postpone that so that you will be well-rested when you choose to deal with the Bad Thing™ later at your convenience.
So remember: identify the positive (with a single word), and anything else, just release.

Broccoli vs Cauliflower – 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 broccoli to cauliflower, we picked the broccoli.
Why?
This one is quite straightforward. Superficially, they’re very similar:
Both are great cruciferous vegetables with many health benefits to offer. Even for those keen to avoid oxalates, which cruciferous vegetables in general can be high in, these ones are quite low.
However, if you have IBS, you might want to avoid both, for their raffinose content that may cause problems for you.
For pretty much everyone else, unless you have a special reason why it’s not the case for you, both are a good source of abundant vitamins and minerals, and yet…
Anything cauliflower can do, broccoli can do better!
Broccoli contains more of the vitamins they both contain, and more of the minerals they both contain.
Broccoli also beats cauliflower on amino acids (except lysine), and contains a lot more lutein and zeaxanthin, carotenoids important for healthy eyes and brain.
So by all means enjoy both, but if you’re going to pick one, pick broccoli!

Basic Baked Tofu
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 of the main criticisms of tofu is that it is tasteless. Well, so is flour, but you’re not supposed to eat it plain, and the same goes for tofu. It’s a blank canvas that you get to decide what to do with—not to mention, it’s a canvas that’s very high in protein, and is a complete protein too, containing all essential amino acids. Anyway, here’s a starter recipe that elevates tofu from “nutrition” to “nutritious tasty snack”!
We were going to do a fancier recipe today, but considered that it might be judicious to cover this basic element first, that can be incorporated into a larger recipe later, a bit like we have done with recipes such as our Tasty Versatile Rice, and Plant-Based Healthy Cream Cheese (amongst others).
You will need
- 1 block of extra-firm tofu; these are quite standardized in size; it should be about 12oz; don’t worry if it’s a little more or less.
- 2 tbsp arrowroot powder (or potato starch if you don’t have arrowroot)
- 1½ tbsp extra virgin olive oil
- 1 tbsp nutritional yeast
- 1 tsp black pepper
- ½ tsp MSG or 1 tsp low-sodium salt
- Optional: ½ tsp garlic powder
- Optional: ½ tsp ground turmeric
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 425ºF / 220ºC.
2) Press the tofu for about 15 minutes (to remove excess moisture), using a tofu press if you have one. If you don’t, then here is an example product on Amazon, or alternatively, you can go with the time-honored tradition of cutting the tofu lengthways into slabs, and wrapping it in a lint-free kitchen towel or muslin cloth, and pressing it with heavy books. We don’t recommend pressing for more than about 15 minutes, as you are going to bake the tofu so you don’t want it too dry going in.
3) Cut the tofu into cubes. Size is up to you, but half-inch cubes are very respectable.
4) Combine the tofu cubes in a big bowl with the oil and seasonings, including the nutritional yeast but not the arrowroot powder or potato starch yet. You will need to toss them gently (very gently; they are fragile!) to combine.
5) Add the arrowroot powder or potato starch, and again toss gently to combine. We do this last, because it would stop the other things from sticking properly if we did it earlier.
6) Arrange the tofu on a baking tray lined with baking paper, in a single layer so that the cubes don’t touch. Bake for 15 minutes, turn them over, and bake for a further 15 minutes on the other side. They should now be golden and crisp, but if they’re not, just give them a little more time.
7) Serve as a snack, or set aside for whatever else you’re going to do with them in a larger more complex recipe.
Enjoy!

The SharpBrains Guide to Brain Fitness – by Alvaro Fernandez et al.
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.
We say “et al.” in the by-line, because this one has a flock of authors, including Dr. Pascale Michelon, Dr. Sandra Bond Chapman, Dr. Elkehon Goldberg, and various others if we include the foreword, introduction, etc.
This is relevant, because those who contributed to the meat of the book (i.e., those listed above), it makes the work a lot more scientifically reliable; one skilled science writer might make a mistake; it’s much less likely to make it through to publication when there are a bevy of doctors in the mix, each staking their reputation on the book’s content, and thus having a vested interest in checking each other’s work as well as their own.
As for what this multidisciplinary team have to offer? The book covers such things as:
- how the brain works (especially the possibilities of neuroplasticity), and what that means for such things as memory and attention
- being “a coach not a patient”; i.e., being active rather than passive in one’s approach to brain health
- the relevance of physical exercise, how much, and what kind
- the relevance (and limitations) of diet choices for brain health
- the relevance of such things as learning new languages and musical training
- the relevance of social engagement, and how some (but not all) social engagement can boost cognition
- methods for managing stress and building resilience to same (critical for maintaining a healthy brain)
- “cross-fit for your brain”, that is to say, a multi-vector collection of tools to explore, ranging from meditation to CBT to biofeedback and more.
The style is pop-science without being sensationalist, just communicating ideas clearly, with enough padding to feel casual, and not like a dense read. Importantly, it’s also practical and applicable too, which is something we always look for here.
Bottom line: if you’d like to be given a good overview of what things work (and how much they can be expected to work), along with a good framework to put that knowledge into practice, then this is a great book for you.
