Just One Thing – by Dr. Michael Mosley

This is a collection of easy-to-implement changes that have good science behind them to show how they can benefit us. Some things are obvious (e.g: drink water); others, less so (e.g: sing, to reduce inflammation).
The book is divided thematically into times of the day, though in many cases it’s not a hard rule that a thing needs to be done at a certain time. Others are, like a cold shower in the morning and hot bath before bed—you might not want to switch those around!
The style is very pop-science, and does not have in-line citations for claims, but it does have a bibliography in the bag organized by each “one thing”, e.g. it might say “get some houseplants” and then list a number of references supporting that, with links to the studies showing how that helps. For those with the paper version, don’t worry, you can copy the URL from the book into your browser and see it that way. In any case, there are 2–6 scientific references for each claim, which is very respectable for a pop-sci book.
Bottom line: if you’re looking for evidence-based “one little thing” changes that can make a big difference, this book has lots!

Hypertension: Factors Far More Relevant Than Salt
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.
Hypertension: Factors Far More Relevant Than Salt
Firstly, what is high blood pressure vs normal, and what do those blood pressure readings mean?
Rather than take up undue space here, we’ll just quickly link to…
Blood Pressure Readings Explained (With A Colorful Chart)
More details of specifics, at:
Hypotension | Normal | Elevated | Stage 1 | Stage 2 | Danger zone
Keeping Blood Pressure Down
As with most health-related things (and in fact, much of life in general), prevention is better than cure.
People usually know “limit salt” and “manage stress”, but there’s a lot more to it!
Salt isn’t as big a factor as you probably think
That doesn’t mean go crazy on the salt, as it can cause a lot of other problems, including organ failure. But it does mean that you can’t skip the salt and assume your blood pressure will take care of itself.
This paper, for example, considers “high” sodium consumption to be more than 5g per day, and urinary excretion under 3g per day is considered to represent a low sodium dietary intake:
Sodium Intake and Hypertension
Meanwhile, health organizations often recommend to keep sodium intake to under 2g or under 1.5g
Top tip: if you replace your table salt with “reduced sodium” salt, this is usually sodium chloride (regular table salt) cut with potassium chloride, which is almost as “salty” tastewise, but obviously contains less sodium. Not only that, but potassium actually helps the body eliminate sodium, too.
The rest of what you eat is important too
The Mediterranean Diet is as great for this as it is for most health conditions.
If you sometimes see the DASH diet mentioned, that stands for “Dietary Approaches to Stop Hypertension”, and is basically the Mediterranean Diet with a few tweaks.
What are the tweaks?
- Beans went down a bit in priority
- Red meat got removed entirely instead of “limit to a tiny amount”
- Olive oil was deprioritized, and/but vegetable oil is at the bottom of the list (i.e., use sparingly)
You can check out the details here, with an overview and examples:
DASH Eating Plan—Description, Charts, and Recipes
Don’t drink or smoke
And no, a glass of red a day will not help your heart. Alcohol does make us feel relaxed, but that is because of what it does to our brain, not what it does to our heart.
In reality, even a single drink will increase blood pressure. Yes, really:
And smoking? It’s so bad that even second-hand smoke increases blood pressure:
Get those Zs in
Sleep is a commonly underestimated/forgotten part of health, precisely because in a way, we’re not there for it when it happens. We sleep through it! But it is important, including to protect against hypertension:
Short- and long-term health consequences of sleep disruption
Move your body!
Moving your body often is far more important for your heart than running marathons or bench-pressing your spouse.
Those 150 minutes “moderate exercise” (e.g. walking) per week are important, and can be for example:
- 22 minutes per day, 7 days per week
- 25 minutes per day, 6 days per week
- 30 minutes per day, 5 days per week
- 75 minutes per day, 2 days per week

Future-Proof 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.
This is Kimberly Wilson. She’s a psychologist, not a doctor, and/but her speciality is neurophysiology and brain health.
Here’s what she wants us to know…
Avoid this very common killer
As you’re probably aware, the #1 killer in the US is heart disease, followed by COVID, which effectively pushed everything down a place. Thereafter, we see cancer, followed by accidental injuries, stroke, and dementia (including Alzheimer’s).
Over in the UK, where Wilson is from, dementia (including Alzheimer’s disease) is the #1 killer, followed by heart disease and then respiratory diseases (including COVID), and then stroke, then cancer.
As ever, what’s good for the heart is good for the brain, so many of the same interventions will help avoid both. With regard to some of the other differences in order, the reasons are mostly due to differences in the two countries’ healthcare systems and firearms laws.
It’s worth noting, though, that the leading cause of death in young people (aged 15–19) is suicide in the UK; in the US it’s nominally accidental injuries first (e.g. accidental shootings) with intentional suicide in the second spot.
In other words… Young or old, mental health is a serious health category that kills literally the most people in the UK, and also makes the top spots in the US.
Avoid the early killer
Given the demographics of most of our readership, chances are you’ve already lived past your teens and twenties. That’s not to say that suicide is no longer a risk, though, and it’s also worth noting that while mental health issues are invisible, they’re still physical illnesses (the brain is also an organ, after all!), so this isn’t something where you can simply “decide not to” and that’s you set, safe for life. So, please do continue to take good care in that regard.
We wrote about this previously, here:
How To Stay Alive (When You Really Don’t Want To)
Avoid the later killer
Wilson talks about how a recent survey found that…
- while nearly half of adults say dementia is the disease they fear most,
- only a third of those thought you could do anything to avoid it, and
- just 1% could name the 7 known risk factors.
Quick test: can you name the 7 known risk factors?
Please take a moment to actually try (this kind of mental stimulation is good in any case), and count them out on your fingers (or write them down), and then…
When you’re ready: click here to see the answer!
How many did you get? If you got them all, well done. If not, then well, now you know, so that’s good.
So, with those 7 things in mind, the first obvious advice is to take care of those things.
Taking an evidence-based medicine approach, Wilson recommends some specific interventions that will each improve one or more of those things, directly or indirectly:
Eating right
Wilson is a big fan of “nutritional psychiatry” and feeding one’s brain properly. We wrote about this, here:
The 6 Pillars Of Nutritional Psychiatry
As well as agreeing with the obvious “eat plenty of fiber, different-colored plants, and plenty of greens and beans”, Wilson specifically also champions getting enough of vitamins B9, B12, and D, as well as getting a healthy dose of omega-3 fatty acids.
She also recommends intermittent fasting, if that’s a reasonable option for you—but advocates for not worrying about it, if it’s not easy for you. For example, if you are diabetic, or have (or have a history with) some kind of eating disorder(s), then it’s probably not usefully practicable. But for most people, it can reduce systemic inflammation, which means also reducing neuroinflammation.
Managing stress right
Here she advocates for three main things:
- Mindful meditation (see: Evidence-Based, No-Frills Mindfulness)
- Psychological resilience (see: Building Psychological Resilience)
- Mindful social media use (see: Making Social Media Work For Your Mental Health)
Managing money right
Not often we talk about this in a health science publication as opposed to a financial planning publication, but the fact is that a lot of mental distress, which goes on to have a huge impact on the brain, is rooted in financial stresses.
And, of course, it’s good to be able to draw on financial resources to directly fund one’s good health, but that is the secondary consideration here—the financial stress is the biggest issue, and you can’t CBT your way out of debt, for example.
Therapists often face this, and what has been referred to informally by professionals in the field as “Shit Life Syndrome”—and there’s only so much that therapy can do about that.
We’re not a financial publication, but one recommendation we’ll drop is that if you don’t currently have budgeting software that you use, this writer personally uses and swears by YNAB (You Need A Budget), so maybe check that out if you don’t already have everything covered in that regard. It’s not free, but there is a 34-day free trial.
Therapy can be very worthwhile nonetheless
Wilson notes that therapy is like non-invasive brain surgery (because of neuroplasticity, it’s literally changing physical things in your brain).
It’s not a magic bullet and it’s not the right choice for everyone, but it’s worth considering, and even self-therapy can yield benefits for many:

Sleeping right
Sleep is not only critical for health in general and brain health in particular, it’s also most of when our glymphatic system does clean-up in the brain (essential for avoiding Alzheimer’s & Parkinson’s, amongst other diseases):

A Fresh Take On Hypothyroidism
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 Three Rs To Boost Thyroid-Related Energy Levels
This is Dr. Izabella Wentz. She’s a doctor of pharmacology, and after her own diagnosis with Hashimoto’s thyroiditis, she has taken it up as her personal goal to educate others on managing hypothyroidism.
Dr. Wentz is also trained in functional medicine through The Institute for Functional Medicine, Kalish Functional Medicine, and the American Academy of Anti-Aging Medicine. She is a Fellow of the American Society of Consultant Pharmacists, and holds certifications in Medication Therapy Management as well as Advanced Diabetes Care through the American Pharmacists Association. In 2013, she received the Excellence in Innovation Award from the Illinois Pharmacists Association.
Dr. Wentz’s mission
Dr. Wentz was disenchanted by the general medical response to hypothyroidism in three main ways. She tells us:
- Thyroid patients are not diagnosed appropriately.
- For this, she criticises over-reliance on TSH tests that aren’t a reliable marker of thyroid function, especially if you have Hashimoto’s.
- Patients should be better optimized on their medications.
- For this, she criticizes many prescribed drugs that are actually pro-drugs*, that don’t get converted adequately if you have an underactive thyroid.
- Lifestyle interventions are often ignored by mainstream medicine.
- Medicines are great; they truly are. But medicating without adjusting lifestyle can be like painting over the cracks in a crumbling building.
*a “pro-drug” is what it’s called when the drug we take is not the actual drug the body needs, but is a precursor that will get converted to that actual drug we need, inside our body—usually by the liver, but not always. An example in this case is T4, which by definition is a pro-drug and won’t always get correctly converted to the T3 that a thyroid patient needs.
Well that does indeed sound worthy of criticism. But what does she advise instead?
First, she recommends a different diagnostic tool
Instead of (or at least, in addition to) TSH tests, she advises to ask for TPO tests (thyroid peroxidase), and a test for Tg antibodies (thyroglobulin). She says these are elevated for many years before a change in TSH is seen.
Next, identify the root cause and triggers
These can differ from person to person, but in countries that add iodine to salt, that’s often a big factor. And while gluten may or may not be a factor, there’s a strong correlation between celiac disease and Hashimoto’s disease, so it is worth checking too. Same goes for lactose.
By “checking”, here we mean testing eliminating it and seeing whether it makes a difference to energy levels—this can be slow, though, so give it time! It is best to do this under the guidance of a specialist if you can, of course.
Next, get to work on repairing your insides.
Remember we said “this can be slow”? It’s because your insides won’t necessarily bounce back immediately from whatever they’ve been suffering from for what’s likely many years. But, better late than never, and the time will pass anyway, so might as well get going on it.
For this, she recommends a gut-healthy diet with specific dietary interventions for hypothyroidism. Rather than repeat ourselves unduly here, we’ll link to a couple of previous articles of ours, as her recommendations match these:
She also recommends regular blood testing to see if you need supplementary TSH, TPO antibodies, and T3 and T4 hormones—as well as vitamin B12.
Short version
After diagnosis, she recommends the three Rs:
- Remove the causes and triggers of your hypothyroidism, so far as possible
- Repair the damage caused to your body, especially your gut
- Replace the thyroid hormones and related things in which your body has become deficient
Learn more
If you’d like to learn more about this, she offers a resource page, with resources ranging from on-screen information, to books you can get, to links to hook you up with blood tests if you need them, as well as recommended supplements to consider.
She also has a blog, which has an interesting relevant article added weekly.
Enjoy, and take care of yourself!

Nasal Hair; How Far To Go?
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.
t’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
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
❝As a man in his sixties I find I need to trim my nasal hair quite frequently, otherwise it sticks out in an unsightly manner. But I’m never sure how severely I should cut the hairs back, or even how best to do it. Please advise.❞
As you might know, those hairs are really important for our health, so let’s start by mentioning that yes, trimming is the way, not plucking!
In an ideal world, we’d not trim them further back than the entrance to our nostrils, but given the constant nature of hair-growing, that could become a Sisyphean task.
A good compromise, if you’re not up for trimming when you get up and having visible hairs by evening, is to put the scissors away (if you haven’t already) and use a nasal hair trimmer; these are good at a) trimming nasal hairs b) abstaining from trimming them too far back.
By all means shop around, but here’s an example product on Amazon, for your convenience!
- Note 1: despite the product description, please do not stick this in your ear (or any other orifice that’s not your nose, for the love of all that is holey)
- Note 2: we chose that one for a reason; the shape of the head prevents overtrimming.
- In contrast, we do not recommend this cheaper one that has a different shape head for a closer trim, which in this case, is not what we want.
Enjoy!

Wholewheat Bread vs Seeded White – 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 wholewheat bread to seeded bread, we picked the wholewheat.
Why?
First, we will acknowledge that this is a false dichotomy; it is possible to have seeded wholewheat bread. However, it is very common to have wholewheat bread that isn’t seeded, and white bread that is seeded. So, it’s important to be able to decide which is the healthier option, since very often, this false dichotomy is what’s on offer.
We will also advise checking labels (or the baker, if getting from a bakery) to ensure that visibly brown bread is actually wholewheat, and not just dyed brown with caramel coloring or such (yes, that is a thing that some companies do).
Now, as for why we chose the wholewheat over the seeded white…
In terms of macronutrients, wholewheat bread has (on average; individual breads may vary of course) has 2x the protein and a lot more fiber.
Those seeds in seeded bread? They just aren’t enough to make a big impact on the overall nutritional value of the bread in those regards. Per slice, you are getting, what, 10 seeds maybe? This is not a meaningful dietary source of much.
Seeded bread does have proportionally more healthy fats, but the doses are still so low as to make it not worth the while; it just looks like a lot of expressed as a percentage of comparison, because of the wholewheat bread has trace amounts, and the seeded bread has several times those trace amounts, it’s still a tiny amount. So, we’d recommend looking to other sources for those healthy fats.
Maybe dip your bread, of whatever kind, into extra virgin olive oil, for example.
Wholewheat bread of course also has a lower glycemic index. Those seeds in seeded white bread don’t really slow it down at all, because they’re not digested until later.

Think Again – by Adam Grant
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.
Warning: this book may cause some feelings of self-doubt! Ride them out and see where they go, though.
It was Socrates who famously (allegedly) said “ἓν οἶδα ὅτι οὐδὲν οἶδα”—”I know that I know nothing”.
Adam Grant wants us to take this philosophy and apply it usefully to modern life. How?
The main premise is that rethinking our plans, answers and decisions is a good thing… Not a weakness. In contrast, he says, a fixed mindset closes us to opportunities—and better alternatives.
He wants us to be sure that we don’t fall into the trap of the Dunning-Kruger Effect (overestimating our abilities because of being unaware of how little we know), but he also wants us to rethink whole strategies, too. For example:
Grant’s approach to interpersonal conflict is very remniscent of another book we might review sometime, “Aikido in Everyday Life“. The idea here is to not give in to our knee-jerk responses to simply retaliate in kind, but rather to sidestep, pivot, redirect. This is, admittedly, the kind of “rethinking” that one usually has to rethink in advance—it’s too late in the moment! Hence the value of a book.
Nor is the book unduly subjective. “Wishy-washiness” has a bad rep, but Grant gives us plenty in the way of data and examples of how we can, for example, avoid losses by not doubling down on a mistake.
What, then, of strongly-held core principles? Rethinking doesn’t mean we must change our mind—it simply means being open to the possibility in contexts where such makes sense.
Grant borrows, in effect, from:
❝Do the best you can until you know better. Then when you know better… do better!❞
So, not so much undercutting the principles we hold dear, and instead rather making sure they stand on firm foundations.
All in all, a thought-provokingly inspiring read!
