Salt’s Health Risks… More Than Just Heart Disease!
It’s been well-established for a long time that too much salt is bad for cardiovascular health. It can lead to high blood pressure, which in turn can lead to many problems, including heart attacks.
A team of researchers has found that in addition to this, it may be damaging your organs themselves.
This is because high salt levels peel away the surfaces of blood vessels. How does this harm your organs? Because it’s through those walls that nutrients are selectively passed to where they need to be—mostly your organs. So, too much salt can indirectly starve your organs of the nutrients they need to survive. And you absolutely do not want your organs to fail!
❝We’ve identified new biomarkers for diagnosing blood vessel damage, identifying patients at risk of heart attack and stroke, and developing new drug targets for therapy for a range of blood vessel diseases, including heart, kidney and lung diseases as well as dementia❞

Diets high in salt are a huge problem in Canada, North America as a whole, and around the world. According to a World Health Organization (WHO) report released March 9, Canadians consume 9.1 grams of salt per day.

You may be wondering: who is eating over 9g of salt per day?
And the answer is: mostly, people who don’t notice how much salt is already in processed foods… don’t see it, and don’t think about it.
Meanwhile, the WHO recommends the average person to consume no more than five grams, or one teaspoon, of salt per day.

The American Heart Association, tasked with improving public health with respect to the #1 killer of Americans (it’s also the #1 killer worldwide—but that’s not the AHA’s problem), goes further! It recommends no more than 2.3g per day, and ideally, no more than 1.5g per day.
Some handy rules-of-thumb
Here are sodium-related terms you may see on food packages:
- Salt/Sodium-Free = Less than 5mg of sodium per serving
- Very Low Sodium = 35mg or less per serving
- Low Sodium = 140mg or less per serving
- Reduced Sodium = At least 25% less sodium per serving than the usual sodium level
- Light in Sodium or Lightly Salted = At least 50% less sodium than the regular product
Confused by milligrams? Instead of remembering how many places to move the decimal point (and potentially getting an “out by an order of magnitude error—we’ve all been there!), think of the 1.5g total allowance as being 1500mg.

So, no question/request too big or small
❝Any idea about the latest research on the most effective exercises for osteoporosis?❞
While there isn’t much new of late in this regard, there is plenty of research!
First, what you might want to avoid:
- Sit-ups, and other exercises with a lot of repeated spinal flexion
- Running, and other high-impact exercises
- Skiing, horse-riding, and other activities with a high risk of falling
- Golf and tennis (both disproportionately likely to result in injuries to wrists, elbows, and knees)
Next, what you might want to bear in mind:
While in principle resistance training is good for building strong bones, good form becomes all the more important if you have osteoporosis, so consider working with a trainer if you’re not 100% certain you know what you’re doing:
Some of the best exercises for osteoporosis are isometric exercises:

What Curiosity Really Kills
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.
Curiosity Kills The Neurodegeneration
Of the seven things that Leonardo da Vinci considered most important for developing and maintaining the mind, number one on his list was curiosity, and we’re going to be focussing on that today.
In case you are curious about what seven things made Leonardo’s* list, they were:
- Curiosità: an insatiably curious approach to life and an unrelenting quest for continuous learning
- Dimostrazione: a commitment to test knowledge through experience, persistence, and a willingness to learn from mistakes
- Sensazione: the continual refinement of the senses, especially sight, as a means to enliven experience
- Sfumato: (lit: “gone up in smoke”) a willingness to embrace ambiguity, paradox, and uncertainty
- Arte/Scienza: the curated balance of art and science, imagination and logic
- Corporalità: the cultivation of physical grace, ambidexterity, and fitness
- Connessione: a recognition of and appreciation for the interconnectedness of phenomena (systems-based thinking)
*In case you are curious why we wrote “Leonardo” and not “da Vinci” as per our usual convention of shortening names to last names, da Vinci is not technically a name, in much the same way as “of Nazareth” was not a name.
You can read more about all 7 of these in a book that we’ve reviewed previously:
How to Think Like Leonardo da Vinci: Seven Steps to Genius Every Day – by Michael J. Gelb
But for now, let’s take on “curiosity”!
If you need an extra reason to focus on growing and nurturing your curiosity, it was also #1 of Dr. Daniel Levitin’s list of…
The Five Keys Of Aging Healthily
…and that’s from a modern-day neuroscientist whose research focuses on aging, the brain, health, productivity, and creativity.
But how do we foster curiosity in the age of Google?
Curiosity is like a muscle: use it or lose it
While it’s true that many things can be Googled to satisfy one’s curiosity in an instant…
- do you? It’s only useful if you do use it
- is the top result on Google reliable?
- there are many things that aren’t available there
In short: douse “fast
foodinformation” sources, but don’t rely on them! Not just for the sake of having correct information, but also: for the actual brain benefits which is what we are aiming for here with today’s article.If you want the best brain benefits, dive in, and go deep
Here at 10almonds we often present superficial information, with links to deeper information (often: scholarly articles). We do this because a) there’s only so much we can fit in our articles and b) we know you only have so much time available, and/but may choose to dive deeper.
Think of it in layers, e.g:
- Collagen is good for joints and bones
- Collagen is a protein made of these amino acids that also requires these vitamins and minerals to be present in order to formulate it
- Those amino acids are needed in these quantities, of which this particular one is usually the weakest link that might need supplementing, and those vitamins and minerals need to be within this period of time, but not these ones at the exact same time, or else it will disrupt the process of collagen synthesis
(in case you’re curious, we covered this here and here and offered a very good, very in-depth book about it here)
Now, this doesn’t mean that to have a healthy brain you need to have the equivalent knowledge of an anatomy & physiology degree, but it is good to have that level of curiosity in at least some areas of your life—and the more, the better.
Top tips for developing a habit of curiosity
As you probably know, most of our endeavors as humans go best when they are habits:
How To Really Pick Up (And Keep!) Those Habits
And as for specifically building a habit of curiosity:
- Make a deal with yourself that when someone is excited to tell you what they know about something (no matter whether it is your grandkid, or the socially awkward nerd at a party, or whoever), listen and learn, no matter the topic.
- Learn at least one language other than your native language (presumably English for most of our readers). Not only does learning a language convey a lot of brain benefits of its own, but also, it is almost impossible to separate language learning from cultural learning, and so you will learn a lot about another culture too, and have whole new worlds opened up to you. Again, more is better, but one second language is already a lot better than none.
- Make a regular habit of going to your local library, and picking out a non-fiction book to take home and read. This has an advantage over a bookshop, by the way (and not just that the library is free): since library books must be returned, you will keep going back, and build a habit of taking out books.
- Pick a skill that you’d like to make into a fully-fledged hobby, and commit to continually learning as much about it as you can. We already covered language-learning above, but others might include: gardening (perhaps a specific kind), cooking (perhaps a specific kind), needlecraft (perhaps a specific kind), dance (perhaps a specific kind). You could learn a musical instrument. Or it could be something very directly useful, like learning to be a first responder in case of emergencies, and committing to continually learning more about it (because there is always more to learn).
And when it comes to the above choices… Pick things that excite you, regardless of how practical or not they are. Because that stimulation that keeps on driving you? That’s what keeps your brain active, healthy, and sharp.
Enjoy!

The Art of Being Unflappable (Tricks For Daily Life)
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 Art of Being Unflappable
From Stoicism to CBT, thinkers through the ages have sought the unflappable life.
Today, in true 10almonds fashion, we’re going to distil it down to some concentrated essentials that we can all apply in our daily lives:
Most Common/Impactful Cognitive Distortions To Catch (And Thus Avoid)
These are like the rhetorical fallacies with which you might be familiar (ad hominem, no true Scotsman, begging the question, tu quoque, straw man, etc), but are about what goes on between your own ears, pertaining to your own life.
If we learn about them and how to recognize them, however, we can catch them before they sabotage us, and remain “unflappable” in situations that could otherwise turn disastrous.
Let’s take a look at a few:
Catastrophizing / Crystal Ball
- Distortion: not just blowing something out of proportion, but taking an idea and running with it to its worst possible conclusion. For example, we cook one meal that’s a “miss” and conclude we are a terrible cook, and in fact for this reason a terrible housewife/mother/friend/etc, and for this reason everyone will probably abandon us and would be right to do so
- Reality: by tomorrow, you’ll probably be the only one who even remembers it happened
Mind Reading
- Distortion: attributing motivations that may or may not be there, and making assumptions about other people’s thoughts/feelings. An example is the joke about two partners’ diary entries; one is long and full of feelings about how the other is surely dissatisfied in their marriage, has been acting “off” with them all day, is closed and distant, probably wants to divorce, may be having an affair and is wondering which way to jump, and/or is just wondering how to break the news—the other partner’s diary entry is short, and reads “motorcycle won’t start; can’t figure out why”
- Reality: sometimes, asking open questions is better than guessing, and much better than assuming!
All-or-Nothing Thinking / Disqualifying the Positive / Magnifying the Negative
- Distortion: having a negative bias that not only finds a cloud in every silver lining, but stretches it out so that it’s all that we can see. In a relationship, this might mean that one argument makes us feel like our relationship is nothing but strife. In life in general, it may lead us to feel like we are “naturally unlucky”.
- Reality: those negative things wouldn’t even register as negative to us if there weren’t a commensurate positive we’ve experienced to hold them in contrast against. So, find and remember that positive too.
For brevity, we put a spotlight on (and in some cases, clumped together) the ones we think have the most bang-for-buck to know about, but there are many more.
So for the curious, here’s some further reading:

Omega-3 Mushroom Spaghetti
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 omega-3 is not the only healthy fat in here; we’re also going to have medium-chain triglycerides, as well as monounsaturates. Add in the ergothioneine from the mushrooms and a stack of polyphenols from, well, most of the ingredients, not to mention the fiber, and this comes together as a very healthy dish. There’s also about 64g protein in the entire recipe, so you do the math for how much that is per serving, depending on how big you want the servings to be.
You will need
- 1lb wholewheat spaghetti (or gluten-free equivalent, such as a legume-based pasta, if avoiding gluten/wheat)
- 12oz mushrooms, sliced (any non-poisonous edible variety)
- ½ cup coconut milk
- ½ onion, finely chopped
- ¼ cup chia seeds
- ¼ bulb garlic, minced (or more, if you like)
- 2 tbsp extra virgin olive oil
- 1 tbsp black pepper, coarse ground
- 1 tbsp lime juice
Method
(we suggest you read everything at least once before doing anything)
1) Cook the spaghetti according to packet instructions, or your own good sense, aiming for al dente. When it’s done, drain it, and lastly rinse it (with cold water), and set it aside.
2) Heat the olive oil in a skillet and add the onion, cooking for 5 minutes
3) Add the garlic, mushrooms, and black pepper, cooking for another 8 minutes.
4) Add the coconut milk, lime juice, and chia seeds, stirring well and cooking for a further two minutes
5) Reheat the spaghetti by passing boiling water through it in a colander (the time it spent cold was good for it; it lowered the glycemic index)
6) Serve, adding the mushroom sauce to the spaghetti:
Enjoy!

Delay Ageing – by Dr. Colin Rose
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.
Note: the title is spelled that way because it is British English. We generally write in US English here at 10almonds, but we’ll first quote directly from Dr. Rose as written:
❝I have written Delay Ageing because there is some very important recent University research on ageing and age related illness that deserves to be made accessible to a general audience.❞
What is this research? Well, there’s quite a lot over its 300-odd pages (exact number depends on the edition and whether we count end matter), and most of it is tweaks and refinements on things with which you’ll probably be at least brushingly familiar if you’re a regular 10almonds reader.
Dr. Rose addresses the nine hallmarks of aging, of which there are ten, ranging from such things as “telomeres get shorter” and “DNA accumulates damage”, to “stem cells become exhausted” and “cells fail to communicate properly”, and asks the question “what if we were to target all these things simultaneously?”.
Rather than going for drugs on drugs on drugs (half of them to deal with undesired side effects of the previous ones), Dr. Cole leaves no stone unturned to find lifestyle interventions that will improve each of these, even if just a little. Because, all those “little” improvements add up and even compound, and on the flipside, mean that factors of aging aren’t adding up and compounding so much or so quickly anymore.
The rather broad umbrella of “lifestyle interventions” obviously includes food under its auspices, and with it, nutraceuticals. So to give one example, if you’re taking a fisetin supplement (a natural senolytic agent), you’ll find science vindicating that here. And much more.
The style is… Less pop-science and more “textbook written for laypersons”, and you may be thinking “isn’t that the same?” and the difference is that the textbook has a lot less polish and finesse, but often more precise information.
Bottom line: if you’d like to combat aging on 10 different fronts with easily implementable lifestyle interventions, and know exactly what is doing what and how, then this is the book for you.

War in Ukraine affected wellbeing worldwide, but people’s speed of recovery depended on their personality
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 war in Ukraine has had impacts around the world. Supply chains have been disrupted, the cost of living has soared and we’ve seen the fastest-growing refugee crisis since World War II. All of these are in addition to the devastating humanitarian and economic impacts within Ukraine.
Our international team was conducting a global study on wellbeing in the lead up to and after the Russian invasion. This provided a unique opportunity to examine the psychological impact of the outbreak of war.
As we explain in a new study published in Nature Communications, we learned the toll on people’s wellbeing was evident across nations, not just in Ukraine. These effects appear to have been temporary – at least for the average person.
But people with certain psychological vulnerabilities struggled to recover from the shock of the war.
Tracking wellbeing during the outbreak of war
People who took part in our study completed a rigorous “experience-sampling” protocol. Specifically, we asked them to report their momentary wellbeing four times per day for a whole month.
Data collection began in October 2021 and continued throughout 2022. So we had been tracking wellbeing around the world during the weeks surrounding the outbreak of war in February 2022.
We also collected measures of personality, along with various sociodemographic variables (including age, gender, political views). This enabled us to assess whether different people responded differently to the crisis. We could also compare these effects across countries.
Our analyses focused primarily on 1,341 participants living in 17 European countries, excluding Ukraine itself (44,894 experience-sampling reports in total). We also expanded these analyses to capture the experiences of 1,735 people living in 43 countries around the world (54,851 experience-sampling reports) – including in Australia.
A global dip in wellbeing
On February 24 2022, the day Russia invaded Ukraine, there was a sharp decline in wellbeing around the world. There was no decline in the month leading up to the outbreak of war, suggesting the change in wellbeing was not already occurring for some other reason.
However, there was a gradual increase in wellbeing during the month after the Russian invasion, suggestive of a “return to baseline” effect. Such effects are commonly reported in psychological research: situations and events that impact our wellbeing often (though not always) do so temporarily.
Unsurprisingly, people in Europe experienced a sharper dip in wellbeing compared to people living elsewhere around the world. Presumably the war was much more salient for those closest to the conflict, compared to those living on an entirely different continent.
Interestingly, day-to-day fluctuations in wellbeing mirrored the salience of the war on social media as events unfolded. Specifically, wellbeing was lower on days when there were more tweets mentioning Ukraine on Twitter/X.
Our results indicate that, on average, it took around two months for people to return to their baseline levels of wellbeing after the invasion.
Different people, different recoveries
There are strong links between our wellbeing and our individual personalities.
However, the dip in wellbeing following the Russian invasion was fairly uniform across individuals. None of the individual factors assessed in our study, including personality and sociodemographic factors, predicted people’s response to the outbreak of war.
On the other hand, personality did play a role in how quickly people recovered. Individual differences in people’s recovery were linked to a personality trait called “stability”. Stability is a broad dimension of personality that combines low neuroticism with high agreeableness and conscientiousness (three traits from the Big Five personality framework).
Stability is so named because it reflects the stability of one’s overall psychological functioning. This can be illustrated by breaking stability down into its three components:
- low neuroticism describes emotional stability. People low in this trait experience less intense negative emotions such as anxiety, fear or anger, in response to negative events
- high agreeableness describes social stability. People high in this trait are generally more cooperative, kind, and motivated to maintain social harmony
- high conscientiousness describes motivational stability. People high in this trait show more effective patterns of goal-directed self-regulation.
So, our data show that people with less stable personalities fared worse in terms of recovering from the impact the war in Ukraine had on wellbeing.
In a supplementary analysis, we found the effect of stability was driven specifically by neuroticism and agreeableness. The fact that people higher in neuroticism recovered more slowly accords with a wealth of research linking this trait with coping difficulties and poor mental health.
These effects of personality on recovery were stronger than those of sociodemographic factors, such as age, gender or political views, which were not statistically significant.
Overall, our findings suggest that people with certain psychological vulnerabilities will often struggle to recover from the shock of global events such as the outbreak of war in Ukraine.
