Most of us learned to walk at a very young age and probably haven’t thought much about it since, except perhaps in a case where some injury made it difficult.
Annabel Streets provides a wonderful guide to not just taking up (or perhaps reclaiming) the joy of walking, but also the science of it in more aspects than most of us have considered:
- The physical mechanics of walking—what’s best?
- Boots or shoes? Barefoot?
- Roads, grass, rougher vegetation… Mud?
- Flora & fauna down to the microbiota that affect us
- How much walking is needed, to be healthy?
- Is there such a thing as too much walking?
- What are the health benefits (or risks) of various kinds of weather?
- Is it better to walk quickly or to walk far?
- What about if we’re carrying some injury?
- What’s going on physiologically when we walk?
- And so much more…
Streets writes with a captivating blend of poetic joie-de-vivre coupled with scientific references.
One moment the book is talking about neuroradiology reports of NO-levels in our blood, the impact of Mycobacterium vaccae, and the studied relationship between daily steps taken and production of oligosaccharide 3′-sialyllactose, and the next it’s all:
“As if the newfound lightness in our limbs has crept into our minds, loosening our everyday cares and constraints…”
And all in all, this book helps remind us that sometimes, science and a sense of wonder can and do (and should!) walk hand-in-hand.

Homeopathy: Evidence So Tiny That It’s Not there?
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.
Homeopathy: Evidence So Tiny That It’s Not There?
Yesterday, we asked you your opinions on homeopathy. The sample size of responses was a little lower than we usually get, but of those who did reply, there was a clear trend:
- A lot of enthusiasm for “Homeopathy works on valid principles and is effective”
- Near equal support for “It may help some people as a complementary therapy”
- Very few people voted for “Science doesn’t know how it works, but it works”; this is probably because people who considered voting for this, voted for the more flexible “It may help some people as a complementary therapy” instead.
- Very few people considered it a dangerous scam and a pseudoscience.
So, what does the science say?
Well, let us start our investigation by checking out the position of the UK’s National Health Service, an organization with a strong focus on providing the least expensive treatments that are effective.
Since homeopathy is very inexpensive to arrange, they will surely want to put it atop their list of treatments, right?
❝Homeopathy is a “treatment” based on the use of highly diluted substances, which practitioners claim can cause the body to heal itself.
There’s been extensive investigation of the effectiveness of homeopathy. There’s no good-quality evidence that homeopathy is effective as a treatment for any health condition.❞
The NHS actually has a lot more to say about that, and you can read their full statement here.
But that’s just one institution. Here’s what Australia’s National Health and Medical Research Council had to say:
❝There was no reliable evidence from research in humans that homeopathy was effective for treating the range of health conditions considered: no good-quality, well-designed studies with enough participants for a meaningful result reported either that homeopathy caused greater health improvements than placebo, or caused health improvements equal to those of another treatment❞
You can read their full statement here.
The American FDA, meanwhile, have a stronger statement:
❝Homeopathic drug products are made from a wide range of substances, including ingredients derived from plants, healthy or diseased animal or human sources, minerals and chemicals, including known poisons. These products have the potential to cause significant and even permanent harm if they are poorly manufactured, since that could lead to contaminated products or products that have potentially toxic ingredients at higher levels than are labeled and/or safe, or if they are marketed as substitute treatments for serious or life-threatening diseases and conditions, or to vulnerable populations.❞
You can read their full statement here.
Homeopathy is a dangerous scam and a pseudoscience: True or False?
False and True, respectively, mostly.
That may be a confusing answer, so let’s elaborate:
- Is it dangerous? Mostly not; it’s mostly just water. However, two possibilities for harm exist:
- Careless preparation could result in a harmful ingredient still being present in the water—and because of the “like cures like” principle, many of the ingredients used in homeopathy are harmful, ranging from heavy metals to plant-based neurotoxins. However, the process of “ultra-dilution” usually removes these so thoroughly that they are absent or otherwise scientifically undetectable.
- Placebo treatment has its place, but could result in “real” treatment going undelivered. This can cause harm if the “real” treatment was critically needed, especially if it was needed on a short timescale.
- Is it a scam? Probably mostly not; to be a scam requires malintent. Most practitioners probably believe in what they are practising.
- Is it a pseudoscience? With the exception that placebo effect has been highly studied and is a very valid complementary therapy… Yes, aside from that it is a pseudoscience. There is no scientific evidence to support homeopathy’s “like cures like” principle, and there is no scientific evidence to support homeopathy’s “water memory” idea. On the contrary, they go against the commonly understood physics of our world.
It may help some people as a complementary therapy: True or False?
True! Not only is placebo effect very well-studied, but best of all, it can still work as a placebo even if you know that you’re taking a placebo… Provided you also believe that!
Science doesn’t know how it works, but it works: True or False?
False, simply. At best, it performs as a placebo.
Placebo is most effective when it’s a remedy against subjective symptoms, like pain.
However, psychosomatic effect (the effect that our brain has on the rest of our body, to which it is very well-connected) can mean that placebo can also help against objective symptoms, like inflammation.
After all, our body, directed primarily by the brain, can “decide” what immunological defenses to deploy or hold back, for example. This is why placebo can help with conditions as diverse as arthritis (an inflammatory condition) or diabetes (an autoimmune condition, and/or a metabolic condition, depending on type).
Here’s how homeopathy measures up, for those conditions:
(the short answer is “no better than placebo”)
Homeopathy works on valid principles and is effective: True or False?
False, except insofar as placebo is a valid principle and can be effective.
The stated principles of homeopathy—”like cures like” and “water memory”—have no scientific basis.
We’d love to show the science for this, but we cannot prove a negative.
However, the ideas were conceived in 1796, and are tantamount to alchemy. A good scientific attitude means being open-minded to new ideas and testing them. In homeopathy’s case, this has been done, extensively, and more than 200 years of testing later, homeopathy has consistently performed equal to placebo.
In summary…
- If you’re enjoying homeopathic treatment and that’s working for you, great, keep at it.
- If you’re open-minded to enjoying a placebo treatment that may benefit you, be careful, but don’t let us stop you.
- If your condition is serious, please do not delay seeking evidence-based medical treatment.

How To Prevent And Reverse Type 2 Diabetes
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.
Turn back the clock on insulin resistance
This is Dr. Jason Fung. He’s a world-leading expert on intermittent fasting and low carbohydrate approaches to diet. He also co-founded the Intensive Dietary Management Program, later rebranded to the snappier title: The Fasting Method, a program to help people lose weight and reverse type 2 diabetes. Dr. Fung is certified with the Institute for Functional Medicine, for providing functional medicine certification along with educational programs directly accredited by the Accreditation Council for Continuing Medical Education (ACCME).
Why Intermittent Fasting?
Intermittent fasting is a well-established, well-evidenced, healthful practice for most people. In the case of diabetes, it becomes complicated, because if one’s blood sugars are too low during a fasting period, it will need correcting, thus breaking the fast.
Note: this is about preventing and reversing type 2 diabetes. Type 1 is very different, and sadly cannot be prevented or reversed in this fashion.
However, these ideas may still be useful if you have T1D, as you have an even greater need to avoid developing insulin resistance; you obviously don’t want your exogenous insulin to stop working.
Nevertheless, please do confer with your endocrinologist before changing your dietary habits, as they will know your personal physiology and circumstances in ways that we (and Dr. Fung) don’t.
In the case of having type 2 diabetes, again, please still check with your doctor, but the stakes are a lot lower for you, and you will probably be able to fast without incident, depending on your diet itself (more on this later).
Intermittent Fasting can be extra helpful for the body in the case of type 2 diabetes, as it helps give the body a rest from high insulin levels, thus allowing the body to become gradually re-sensitised to insulin.
Why low carbohydrate?
Carbohydrates, especially sugars, especially fructose*, cause excess sugar to be quickly processed by the liver and stored there. When the body’s ability to store glycogen is exceeded, the liver stores energy as fat instead. The resultant fatty liver is a major contributor to insulin resistance, when the liver can’t keep up with the demand; the blood becomes spiked full of unprocessed sugars, and the pancreas must work overtime to produce more and more insulin to deal with that—until the body starts becoming desensitized to insulin. In other words, type 2 diabetes.
There are other factors that affect whether we get type 2 diabetes, for example a genetic predisposition. But, our carb intake is something we can control, so it’s something that Dr. Fung focuses on.
*A word on fructose: actual fruits are usually diabetes-neutral or a net positive due to their fiber and polyphenols.
Fructose as an added ingredient, however, not so much. That stuff zips straight into your veins with nothing to slow it down and nothing to mitigate it.
The advice from Dr. Fung is simple here: cut the carbs. If you are already diabetic and do this with no preparation, you will probably simply suffer hypoglycemia, so instead:
- Enjoy a fibrous starter (a salad, some fruit, or perhaps some nuts)
- Load up with protein first, during your main meal—this will start to trigger your feelings of satedness
- Eat carbs last (preferably whole, unprocessed carbohydrates), and stop eating when 80% full.
Adapting Intermittent Fasting to diabetes
Dr. Fung advocates for starting small, and gradually increasing your fasting period, until, ideally, fasting 16 hours per day. You probably won’t be able to do this immediately, and that’s fine.
You also probably won’t be able to do this, if you don’t also make the dietary adjustments that help to give your liver a break, and thus by knock-on-effect, give your pancreas a break too.
With the dietary adjustments too, however, your insulin production-and-response will start to return to its pre-diabetic state, and finally its healthy state, after which, it’s just a matter of maintenance.

How (And Why) To Train Your Pre-Frontal Cortex
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.
Dr. Chapman’s Keys For Mental Focus
This is Dr. Sandra Chapman; she’s a cognitive neuroscientist, on a mission to, in her words, further our understanding of:
- what makes the brain stronger, faster and last longer
- what enhances human cognitive capacity, and
- what enhances the underlying brain systems across the lifespan.
To this end, she’s also the founder and Chief Director of the Center For Brain Health, where she has worked on her mission for the past 25 years (clocking up hundreds of peer-reviewed publications to her name), as well as being a professor of Behavioral and Brain Sciences at UT Dallas.
What does she want us to know?
Get your brain into gear
When it comes to your brainpower, it is “use it or lose it”, but it is also perfectly possible to use it and lose it.
Why?
Very often, what we are using our brains for is high-strain, low-yield stuff, such as multitasking, overthinking, or overthinking while multitasking. And to make it worse, we often do it without sufficient rest.
This is the equivalent of owning a Ferrari but trying to drive it in second and third gear at once by switching between the two as rapidly as possible. And doing that for 18 hours each day.
Suffice it to say, you’ll be going nowhere quickly.
An alternative “use” of brainpower is low-strain, low-yield stuff, such as having to pay close attention to a boring conversation. It’s enough to stop your mind from doing anything else, but not enough to actually stimulate you.
This is the equivalent of owning a Ferrari but keeping it idling. The wear and tear is minimal this time, but you’re not actually going anywhere either.
Better, of course, are the other two quadrants:
- low-strain, high-yield: consistently using our brain in relatively non-taxing ways that encourage its development
- high-strain, high-yield: here the Ferrari metaphor definitely fails, because unlike cars, our bodies (including our brains) are machines that benefit from judicious regular progressive overloading (but just by a bit, and with adequate recovery time between overloads).
See also: 12 Weeks To Measurably Boost Your Brain
How to do the “low-strain, low-yield” part
When it comes to “what’s the most important part of the brain to help in the face of cognitive decline?” the usual answer is either to focus on memory (hippocampi) or language (various parts, but for example Wernicke’s area and Broca’s area), since people most fear losing memory, and language is very important both socially and practically.
Those are indeed critical, and we at 10almonds stand by them, but Dr. Chapman (herself having originally trained as speech and language pathologist!) makes a strong case for adding a third brain part to the list.
Specifically, she advocates for strengthening the pre-frontal cortex, which is responsible for inhibition, task-switching, working memory, and cognitive flexibility. If that seems like a lot, do remember it’s a whole cortex and not one of the assorted important-but-small brain bits we mentioned above.
How? She has developed training programs for this, based on what she calls Strategic Memory Advanced Reasoning Tactics (SMART), to support support attention, planning, judgment and emotional management.
You can read more about those programs here:
Center For Brain Health | Our Programs
Participation in those is mostly not free, however, if you join their…
Center For Brain Health | BrainHealth Project
…then they will periodically invite you to join pilot programs, research programs, and the like, which will either be free or they-pay-you affairs—because this is how science is done, and you can read about yourself (anonymized, of course) later in peer-reviewed papers of the kind we often cite here.
If you’re not interested in any of that though, we will say that according to Dr. Chapman, the keys are:
Inhibition: be conscious of this function of your brain, and develop it. This is the function of your brain that stops you from making mistakes—or put differently: stops you from saying/doing something stupid.
Switching: do this consciously; per “I am now doing this task, now I am switching to this other task”, rather than doing the gear-grinding thing we discussed earlier
Working memory: this is effectively your brain’s RAM. Unlike the RAM of a computer (can be enhanced by adding another chip or replacing with a bigger chip), our brain’s RAM can be increased by frequent use, and especially by judicious use of progressive overloading (with rests between!) which we’ll discuss in the high-strain, high-yield section.
Flexibility: this is about creative problem-solving, openness to new ideas, and curiosity
See also: Curiosity Kills The Neurodegeneration
How to do the “high-strain, high-yield” part
Delighting this chess-playing writer, Dr. Chapman recommends chess. Although, similar games such as go (a Chinese game that looks simpler than chess but actually requires more calculation) work equally well too.
Why?
Games like chess and go cause structural changes that are particularly helpful, in terms of engaging in such foundational tasks as learning, abstract reasoning, problem-solving and self-control:
Chess Practice as a Protective Factor in Dementia
Basically, it checks (so to speak) a lot of boxes, especially for the pre-frontal cortex. Some notes:
- Focusing on the game is required for brain improvement; simply pushing wood casually will not do it. Ideally, calculating several moves ahead will allow for strong working memory use (because to calculate several moves ahead, one will have to hold increasingly many possible positions in the mind while doing so).
- The speed of play must be sufficiently slow as to allow not only for thinking, but also for what in chess is called “blunder-checking”, in other words, having decided on one’s move, pausing to consider whether it is a mistake, and actively trying to find evidence that it is. This is the crucial “inhibition habit”, and when one does it reflexively, one will make fewer mistakes. Tying this to dementia, see for example how one of the common symptoms of dementia is falling for scams that one wouldn’t have previously. How did cognitive decline make someone naïve? It didn’t, per se; it just took away their ability to, having decided what to do, pause to consider whether it was a mistake, and actively trying to find evidence that it is.
- That “conscious switching” that we talked about, rather than multitasking? In chess, there is a difference between strategy and tactics. Don’t worry about what that difference is for now (learn it if you want to take up chess), but know that strong players will only strategize while it is their opponent’s turn, and only calculate (tactics) while it is their own turn. It’s very tempting to flit constantly between one and the other, but chess requires players to have the mental discipline be able to focus on one task or the other and stick with that task until it’s the appointed time to switch.
If you feel like taking up chess, this site (and related app, if you want it) is free (it’s been funded by voluntary donations for a long time now) and good and even comes with free tuition and training tools: LiChess.org
Here’s another site that this writer (hi, it’s me) personally uses—it has great features too, but many are paywalled (I’m mostly there just because I’ve been there nearly since its inception, so I’m baked into the community now): Chess.com

Tell Yourself a Better Lie – by Marissa Peer
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 humans, we generally lie to ourselves constantly. Or perhaps we really believe some of the things we tell ourselves, even if they’re not objectively necessarily true:
- I’ll always be poor
- I’m destined to be alone
- I don’t deserve good things
- Etc.
Superficially, it’s easy to flip those, and choose to tell oneself the opposite. But it feels hollow and fake, doesn’t it? That’s where Marissa Peer comes in.
Our stories that we tell ourselves don’t start where we are—they’re generally informed by things we learned along the way. Sometimes good lessons, sometimes bad ones. Sometimes things that were absolutely wrong and/or counterproductive.
Peer invites the reader to ask “What if…”, unravel how the unhelpful lessons got wired into our brains in the first place, and then set about untangling them.
“Tell yourself a better lie” does not mean self-deceit. It means that we’re the authors of our own stories, so we might as well make them work for us. Many things in life are genuinely fixed; others are open to interpretation.
Sorting one from the other, and then treating them correctly in a way that’s helpful to us? That’s how we can stop hurting ourselves, and instead bring our own stories around to uplift and fortify us.

Tiramisu Crunch Bites
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.
It’s coffee, it’s creamy, it’s nutty, it’s chocolatey, what’s not to love? It has all the well-loved flavors of tiramisu, but this recipe is a simple one, and it’s essentially stuffed dates in a way you’ve never had them before. They’re delectable, decadent, and decidedly good for your health. These things are little nutrient-bombs that’ll keep you reaching for more.
You will need
- Coffee (we will discuss this)
- 150g (5.5oz) mascarpone (if vegan or lactose-intolerant, can be substituted with vegan varieties, or at a pinch, pressed silken tofu)
- 500g (1lb) dates (Medjool are ideal)
- Twice as many almonds as you have dates
- 50g (2oz) dark chocolate (the darkest, bitterest, you can find)
- Edible flower petals if you can source them (some shops sell dried rose petals for this purpose)
Method
(we suggest you read everything at least once before doing anything)
1) Take the mascarpone and whisk (or blend) it with the coffee. What kind of coffee, you ask? Many will use instant coffee (1tbsp granules mixed with enough boiling water to dissolve it), and that is actually healthiest (counterintuitive but true) but if you care for flavor over health, and have the means to make espresso, make it ristretto (so, stop it halfway through filling up an espresso cup), let it cool, and use that. Absolute bonus for flavor (not for health): if you have the means to make Turkish coffee, use an equivalent amount of that (again, cooled).
You will now have coffee-flavoured mascarpone. It’s great for your gut and full of antioxidant polyphenols. Set it aside for the moment.
2) Take the dark chocolate and melt it. Please don’t microwave it or try to do it in a pan directly over the hob; instead, you will need to use a Bain-Marie. If you don’t have one made-for-purpose, you can place a metal or heatproof glass bowl in a saucepan, with something to stop it from touching the floor of the pan. Then boil water in the pan (without letting the water get into the bowl), and melt the chocolate in the bowl—this will allow you to melt it evenly without burning the chocolate.
You will now have melted dark chocolate. It has its own set of polyphenols, and is great for everything from the brain to the gut microbiome.
3) Cut the dates lengthways on one side and remove the stone. Stuff them carefully with the coffee-flavored mascarpone (you can use a teaspoon, or use a piping kit if you have one). Add a couple of almonds to each one. Place them all on a big plate, and drizzle the melted chocolate over them. Add the petals if you have them.
The dates and almonds deliver extra vitamins and minerals in abundance (not to mention, lots of fiber), and also are an amazing combination even just by themselves. With the mascarpone and chocolate added, this winning on new levels. We’re not done yet, though…
4) Chill them in the fridge for about 30 minutes.
Serve!

Anti-Inflammatory Pineapple Fried Rice
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.
Fried rice is not most people’s go-to when one thinks of health food, but this one is. It’s packed with plenty of nutrients, many of which are anti-inflammatory, but the real star is the pineapple (with its high bromelain content and thus particularly potent benefits).
You will need
- 2½ cups cooked wholegrain basmati rice (you can use our Tasty Versatile Rice recipe if you don’t already have leftovers to use)
- 1 cup pineapple chunks
- ½ red onion, diced
- 1 red bell pepper, diced
- ½ cup sweetcorn
- ½ peas
- 3 green onions, chopped
- 2 serrano peppers, chopped (omit if you don’t care for heat)
- 2 tbsp coconut oil
- 1 tbsp grated fresh ginger
- 1 tbsp black pepper, coarse ground
Method
(we suggest you read everything at least once before doing anything)
1) Fry the red onion, serrano peppers, and ginger in the coconut oil over a medium heat, stirring frequently, for about 3 minutes.
2) Add the pineapple, bell pepper, sweetcorn, peas, and black pepper, stirring frequently, for about another 3 minutes.
3) Add the rice, stirring gently but thoroughly, until fully reheated and mixed in.
4) Serve, garnishing with the green onions.
Enjoy!
