Our Verdict
When comparing chestnuts to hazelnuts, we picked the hazelnuts.
Why?
This one’s not close.
In terms of macros, we have some big difference to start with, since chestnuts contain a lot more water and carbs whereas hazelnuts contain a lot more protein, fats, and fiber. The fats, as with most nuts, are healthy; in this case mostly being monounsaturated fat.
Because of the carbs and fiber being so polarized (i.e., chestnuts have most of the carbs and hazelnuts have most of the fiber), there’s a big difference in glycemic index; chestnuts have a GI of 52 while hazelnuts have a GI of 15.
In the category of vitamins, chestnuts contain more vitamin C, while hazelnuts contain more of vitamins A, B1, B2, B3, B5, B6, and B9.
When it comes to minerals, the story is similar: chestnuts contain a tiny bit more potassium, while hazelnuts contain a lot more calcium, copper, iron, magnesium, manganese, phosphorus, and zinc.
All in all, chestnuts aren’t bad for the health, but hazelnuts are a lot better in almost every way.

How much time should you spend sitting versus standing? New research reveals the perfect mix for optimal health
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.
People have a pretty intuitive sense of what is healthy – standing is better than sitting, exercise is great for overall health and getting good sleep is imperative.
However, if exercise in the evening may disrupt our sleep, or make us feel the need to be more sedentary to recover, a key question emerges – what is the best way to balance our 24 hours to optimise our health?
Our research attempted to answer this for risk factors for heart disease, stroke and diabetes. We found the optimal amount of sleep was 8.3 hours, while for light activity and moderate to vigorous activity, it was best to get 2.2 hours each.
Finding the right balance
Current health guidelines recommend you stick to a sensible regime of moderate-to vigorous-intensity physical activity 2.5–5 hours per week.
However mounting evidence now suggests how you spend your day can have meaningful ramifications for your health. In addition to moderate-to vigorous-intensity physical activity, this means the time you spend sitting, standing, doing light physical activity (such as walking around your house or office) and sleeping.
Our research looked at more than 2,000 adults who wore body sensors that could interpret their physical behaviours, for seven days. This gave us a sense of how they spent their average 24 hours.
At the start of the study participants had their waist circumference, blood sugar and insulin sensitivity measured. The body sensor and assessment data was matched and analysed then tested against health risk markers — such as a heart disease and stroke risk score — to create a model.
Using this model, we fed through thousands of permutations of 24 hours and found the ones with the estimated lowest associations with heart disease risk and blood-glucose levels. This created many optimal mixes of sitting, standing, light and moderate intensity activity.
When we looked at waist circumference, blood sugar, insulin sensitivity and a heart disease and stroke risk score, we noted differing optimal time zones. Where those zones mutually overlapped was ascribed the optimal zone for heart disease and diabetes risk.
You’re doing more physical activity than you think
We found light-intensity physical activity (defined as walking less than 100 steps per minute) – such as walking to the water cooler, the bathroom, or strolling casually with friends – had strong associations with glucose control, and especially in people with type 2 diabetes. This light-intensity physical activity is likely accumulated intermittently throughout the day rather than being a purposeful bout of light exercise.
Our experimental evidence shows that interrupting our sitting regularly with light-physical activity (such as taking a 3–5 minute walk every hour) can improve our metabolism, especially so after lunch.
While the moderate-to-vigorous physical activity time might seem a quite high, at more than 2 hours a day, we defined it as more than 100 steps per minute. This equates to a brisk walk.
It should be noted that these findings are preliminary. This is the first study of heart disease and diabetes risk and the “optimal” 24 hours, and the results will need further confirmation with longer prospective studies.
The data is also cross-sectional. This means that the estimates of time use are correlated with the disease risk factors, meaning it’s unclear whether how participants spent their time influences their risk factors or whether those risk factors influence how someone spends their time.
Australia’s adult physical activity guidelines need updating
Australia’s physical activity guidelines currently only recommend exercise intensity and time. A new set of guidelines are being developed to incorporate 24-hour movement. Soon Australians will be able to use these guidelines to examine their 24 hours and understand where they can make improvements.
While our new research can inform the upcoming guidelines, we should keep in mind that the recommendations are like a north star: something to head towards to improve your health. In principle this means reducing sitting time where possible, increasing standing and light-intensity physical activity, increasing more vigorous intensity physical activity, and aiming for a healthy sleep of 7.5–9 hours per night.
Beneficial changes could come in the form of reducing screen time in the evening or opting for an active commute over driving commute, or prioritising an earlier bed time over watching television in the evening.
It’s also important to acknowledge these are recommendations for an able adult. We all have different considerations, and above all, movement should be fun.

Meditation That You’ll Actually Enjoy

Meditation That You’ll Actually Enjoy
We previously wrote about…
No-Frills, Evidence-Based Mindfulness
this is a great primer, by the way, for the science and simplicity of mindfulness, along with the simplest mindfulness meditation to get you going.
Today, we’re going to have some fun with meditation.
First: The Problem
Once the usefulness and health benefits of meditation have been established, often people want to meditate, but complain they don’t have the time.
But that’s not the real reason, though, is it?
Let’s face it, a basic meditation can give benefits within two minutes. Or within two breaths, for that matter. So, it’s not really for a lack of time.
The real reason is because it doesn’t feel productive, and it’s not fun. For us to feel motivated to do a thing, usually we need at least one or the other. And even if we know it really is productive, it not feeling that way will hobble us.
So instead, let us make things a little more fun, with…
Meditation games!
As it turns out, there are good kinds of meditation with which one can have a little fun.
Catch the next thought
A common feature of many meditative practices is the experience of having fewer, or ideally no, thoughts.
But it’s hard to enact a negative, and thoughts keep coming.
So instead, make yourself comfortable, settle in, and lie in wait for thoughts. When one comes along, pounce on it in your mind. And then release it, and wait for the next.
At first, your thoughts may be coming thick and fast, but soon, you’ll find the pauses between them lengthening, and you have moments of contented not-knowing of what the next thought will be before it comes along.
This state of relaxed, ready alertness, calm and receptive, is exactly what we’re hoping to find here. But don’t worry about that while you’re busy lying in wait for the next wild thought to come along
Counting breaths
Many meditative practices involve focus on one’s breath. But it’s easy for attention to wander!
This game is a simple one. Count your breaths, not trying to change your rate of breathing at all, just letting it be, and see how high you can get before you lose count.
Breathing in and out, once, counts as one breath, by the way.
You may find that your rate of breathing naturally slows while you’re doing this. That’s fine; let it. It’ll add to the challenge of the game, because before long there will be lengthy pauses between each number.
If you lose count, just start again, and see if you can beat your high score.
This meditation game is an excellent exercise to build for sustained focus, while also improving the quality of breathing (as a side-effect of merely paying attention to it).
Hot spot, cold spot
The above two meditation games were drawn from Japanese and Chinese meditative practices, zen and qigong respectively; this one’s from an Indian meditative practice, yoga nidra. But for now, just approach it with a sense of playful curiosity, for best results.
Make yourself comfortable, lying on your back, arms by your sides.
Take a moment first to pay attention to each part of your body from head to toe, and release any tension that you may be holding along the way.
First part: mentally scan your body for where it feels warmest, or most active, or most wanting of attention (for example if there is pain, or an itch, or some other sensation); that’s your “hot spot” for the moment.
Second part: mentally scan your body for where it feels coolest, or most inert, or almost like it’s not a part of your body at all; that’s your “cold spot” for the moment.
Now, see if you can flip them. Whether you can or can’t, notice if your “hot spot” or “cold spot” moves, or if you can move them consciously.
This meditation game is a great exercise to strengthen interoception and somatic awareness in general—essential for being able to “listen to your body”!
Closing thoughts
All three practices above have very serious reasons and great benefits, but make sure you don’t skip enjoyment of the fun aspects!
Being “young at heart” is, in part, to do with the ability to enjoy—literally, to take joy in—the little things in life.
With that in mind, all we have left to say here is…
Enjoy!

Sleep Smarter – by Shawn Stevenson

You probably know to avoid blue light before bed, put a curfew on the caffeine, and have fresh bedding. So, what does this book offer that’s new?
As the subtitle suggests, it’s 21 tips for better sleep, so if even half of them are new, then it’ll still be adding value.
This is a book review, not a book summary, but to give an idea of the kind of thing you might not already know: there’s a section on bedroom houseplants! For example…
- Which plants filter the air best according to NASA, rather than “according to tradition”
- Which plants will thrive in what will hopefully be a cool dark environment
- Which plants produce oxygen even at night, rather than just during the day
The writing style is personable without losing clarity or objectivity:
- We read personal anecdotes, and we read science
- We get “I tried this”, and we get “this sleep study found such-and-such”
- We get not just the “what”, but also the “why” and the “how”
We get the little changes that make a big difference—sometimes the difference between something working or not!
Bottom line: if you’d like to get better sleep and a blue light filter hasn’t wowed you and changed your life, this book will bring your sleep knowledge (and practice) to the next level.

HRT: Bioidentical vs Animal
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.
HRT: A Tale Of Two Approaches
In yesterday’s newsletter, we asked you for your assessment of menopausal hormone replacement therapy (HRT).
- A little over a third said “It can be medically beneficial, but has some minor drawbacks”
- A little under a third said “It helps, but at the cost of increased cancer risk; not worth it”
- Almost as many said “It’s a wondrous cure-all that makes you happier, healthier, and smell nice too”
- Four said “It is a dangerous scam and a sham; “au naturel” is the way to go”
So what does the science say?
Which HRT?
One subscriber who voted for “It’s a wondrous cure-all that makes you healthier, happier, and smell nice too” wrote to add:
❝My answer is based on biodentical hormone replacement therapy. Your survey did not specify.❞
And that’s an important distinction! We did indeed mean bioidentical HRT, because, being completely honest here, this European writer had no idea that Premarin etc were still in such wide circulation in the US.
So to quickly clear up any confusion:
- Bioidentical hormones: these are (as the name suggests) identical on a molecular level to the kind produced by humans.
- Conjugated Equine Estrogens: such as Premarin, come from animals. Indeed, the name “Premarin” comes from “pregnant mare urine”, the substance used to make it.
There are also hormone analogs, such as medroxyprogesterone acetate, which is a progestin and not the same thing as progesterone. Hormone analogs such as the aforementioned MPA are again, a predominantly-American thing—though they did test it first in third-world countries, after testing it on animals and finding it gave them various kinds of cancer (breast, cervical, ovarian, uterine).
A quick jumping-off point if you’re interested in that:
Depot medroxyprogesterone acetate and the risk of breast and gynecologic cancer
this is about its use as a contraceptive (so, much lower doses needed), but it is the same thing sometimes given in the US as part of menopausal HRT. You will note that the date on that research is 1996; DMPA is not exactly cutting-edge and was first widely used in the 1950s.
Similarly, CEEs (like Premarin) have been used since the 1930s, while estradiol (bioidentical estrogen) has been in use since the 1970s.
In short: we recommend being wary of those older kinds and mostly won’t be talking about them here.
Bioidentical hormones are safer: True or False?
True! This is an open-and-shut case:
❝Physiological data and clinical outcomes demonstrate that bioidentical hormones are associated with lower risks, including the risk of breast cancer and cardiovascular disease, and are more efficacious than their synthetic and animal-derived counterparts.
Until evidence is found to the contrary, bioidentical hormones remain the preferred method of HRT. ❞
Further research since that review has further backed up its findings.
Source: Are Bioidentical Hormones Safer or More Efficacious than Other Commonly Used Versions in HRT?
So simply, if you’re going on HRT (estrogen and/or progesterone), you might want to check it’s the bioidentical kind.
HRT can increase the risk of breast cancer: True or False?
Contingently True, but for most people, there is no significant increase in risk.
First: again, we’re talking bioidentical hormones, and in this case, estradiol. Older animal-derived attempts had much higher risks with much lesser efficaciousness.
There have been so many studies on this (alas, none that have been publicised enough to undo the bad PR in the wake of old-fashioned HRT from before the 70s), but here’s a systematic review that highlights some very important things:
❝Estradiol-only therapy carries no risk for breast cancer, while the breast cancer risk varies according to the type of progestogen.
Estradiol therapy combined with medroxyprogesterone, norethisterone and levonorgestrel related to an increased risk of breast cancer, estradiol therapy combined with dydrogesterone and progesterone carries no risk❞
In fewer words:
- Estradiol by itself: no increased risk of breast cancer
- Estradiol with MDPA or other progestogens that aren’t really progesterone: increased risk of breast cancer
- Estradiol with actual progesterone: back to no increased risk of breast cancer
So again, you might want to make sure you are getting actual bioidentical hormones, and not something else!
However! If you are aware that you already have an increased risk of breast cancer (e.g. family history, you’ve had it before, you know you have certain genes for it, etc), then you should certainly discuss that with your doctor, because your personal circumstances may be different:
❝Tailored HRT may be used without strong evidence of a deleterious effect after ovarian cancer, endometrial cancer, most other gynecological cancers, bowel cancer, melanoma, a family history of breast cancer, benign breast disease, in carriers of BRACA mutations, after breast cancer if adjuvant therapy is not being used, past thromboembolism, varicose veins, fibroids and past endometriosis.
Relative contraindications are existing cardiovascular and cerebrovascular disease and breast cancer being treated with adjuvant therapies❞
Source: HRT in difficult circumstances: are there any absolute contraindications?
HRT makes you happier, healthier, and smell nice too: True or False?
Contingently True, assuming you do want its effects, which generally means the restoration of much of the youthful vitality you enjoyed pre-menopause.
The “and smell nice too” was partly rhetorical, but also partly literal: our scent is largely informed by our hormones, and higher estrogen results in a sweeter scent; lower estrogen results in a more bitter scent. Not generally considered an important health matter, but it’s a thing, so hey.
More often, people take menopausal HRT for more energy, stronger bones (reduced osteoporosis risk), healthier heart (reduced CVD risk), improved sexual health, better mood, healthier skin and hair, and general avoidance of menopause symptoms:
Read more: Skin, hair and beyond: the impact of menopause
We’d need another whole main feature to discuss all the benefits properly; today we’re just mythbusting.
HRT does have some drawbacks: True or False?
True, and/but how serious they are (beyond the aforementioned consideration in the case of an already-increased risk of breast cancer) is a matter of opinion.
For example, it is common to get a reprise of monthly cramps and/or mood swings, depending on how one is taking the HRT and other factors (e.g. your own personal physiology and genetic predispositions). For most people, these will even out over time.
It’s also even common to get a reprise of (much slighter than before) monthly bleeding, unless you have for example had a hysterectomy (no uterus = no bleeding). Again, this will usually settle down in a matter of months.
If you experience anything more alarming than that, then indeed check with your doctor.
HRT is a dangerous scam and sham: True or False?
False, simply. As described above, for most people they’re quite safe. Again, talking bioidentical hormones.
The other kind are in the most neutral sense a sham (i.e. they are literally sham hormones), though they’re not without their merits and for many people they may be better than nothing.
As for being a scam, biodentical hormones are widely prescribed in the many countries that have universal healthcare and/or a single-payer healthcare system, where there would be no profit motive (and considerable cost) in doing so.
They’re prescribed because they are effective and thus reduce healthcare spending in other areas (such as treating osteoporosis or CVD after the fact) and improve Health Related Quality of Life, and by extension, health-adjusted life-years, which is one of the top-used metrics for such systems.
See for example:
Our apologies, gentlemen
We wanted to also talk about testosterone therapy for the andropause, but we’ve run out of room today (because of covering the important distinction of bioidentical vs old-fashioned HRT)!
To make it up to you, we’ll do a full main feature on it (it’s an interesting topic) in the near future, so watch this space
Ladies, we’ll also at some point cover the pros and cons of different means of administration, e.g. pills, transdermal gel, injections, patches, pessaries, etc—which often have big differences.
That’ll be in a while though, because we try to vary our topics, so we can’t talk about menopausal HRT all the time, fascinating and important a topic it is.
Meanwhile… take care, all!

Smart Sex – by Dr. Emily Morse
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.
First, what this isn’t: this isn’t a mere book of sex positions and party tricks, nor is it a book of Cosmo-style “drive your man wild by using hot sauce as lube” advice.
What it offers instead, is a refreshingly mature take on sex, free from the “teehee” titillations and blushes that many books of the genre go for.
Dr. Emily Morse outlines five pillars of sex:
- Embodiment
- Health
- Collaboration
- Self-knowledge
- Self-acceptance
…and talks about each of them in detail, and how we can bring them together. And, of course, how we or our partner(s) could accidentally sabotage ourselves or each other, and the conversations we can (and should!) have, to work past that.
She also, critically, and this is a big source of value in the book, looks at “pleasure thieves”: stress, trauma, and shame. The advice for overcoming these is not “don’t worry; be happy” but rather is actual practical steps one can take.
The style throughout is direct and unpatronizing. Since the advice within pertains to everyone who has and/or wants an active sex life, very little is divided by gender etc.
There is some attention given to anatomy and physiology, complete with clear diagrams. Honestly, most people could benefit from these, because most people’s knowledge of the relevant anatomy stopped with a very basic high school text book diagram that missed a lot out.
Bottom line: this book spends more time on what’s between your ears than what’s between your legs, and yet is very comprehensive in all areas. Everyone has something to gain from this one.

Neuroaffirming care values the strengths and differences of autistic people, those with ADHD or other profiles. Here’s how
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’ve come a long way in terms of understanding that everyone thinks, interacts and experiences the world differently. In the past, autistic people, people with attention deficit hyperactive disorder (ADHD) and other profiles were categorised by what they struggled with or couldn’t do.
The concept of neurodiversity, developed by autistic activists in the 1990s, is an emerging area. It promotes the idea that different brains (“neurotypes”) are part of the natural variation of being human – just like “biodiversity” – and they are vital for our survival.
This idea is now being applied to research and to care. At the heart of the National Autism Strategy, currently in development, is neurodiversity-affirming (neuroaffirming) care and practice. But what does this look like?
Unsplash Reframing differences
Neurodiversity challenges the traditional medical model of disability, which views neurological differences solely through a lens of deficits and disorders to be treated or cured.
Instead, it reframes it as a different, and equally valuable, way of experiencing and navigating the world. It emphasises the need for brains that are different from what society considers “neurotypical”, based on averages and expectations. The term “neurodivergent” is applied to Autistic people, those with ADHD, dyslexia and other profiles.
Neuroaffirming care can take many forms depending on each person’s needs and context. It involves accepting and valuing different ways of thinking, learning and experiencing the world. Rather than trying to “fix” or change neurodivergent people to fit into a narrow idea of what’s considered “normal” or “better”, neuroaffirming care takes a person-centered, strengths-based approach. It aims to empower and support unique needs and strengths.
Neuroaffirming care can look different in a school or clinical setting. Shutterstock/Inna Reznik Adaptation and strengths
Drawing on the social model of disability, neuroaffirming care acknowledges there is often disability associated with being different, especially in a world not designed for neurodivergent people. This shift focuses away from the person having to adapt towards improving the person-environment fit.
This can include providing accommodations and adapting environments to make them more accessible. More importantly, it promotes “thriving” through greater participation in society and meaningful activities.
At school, at work, in clinic
In educational settings, this might involve using universal design for learning that benefits all learners.
For example, using systematic synthetic phonics to teach reading and spelling for students with dyslexia can benefit all students. It also could mean incorporating augmentative and alternative communication, such as speech-generating devices, into the classroom.
Teachers might allow extra time for tasks, or allow stimming (repetitive movements or noises) for self-regulation and breaks when needed.
In therapy settings, neuroaffirming care may mean a therapist grows their understanding of autistic culture and learns about how positive social identity can impact self-esteem and wellbeing.
They may make efforts to bridge the gap in communication between different neurotypes, known as the double empathy problem. For example, the therapist may avoid relying on body language or facial expressions (often different in autistic people) to interpret how a client is feeling, instead of listening carefully to what the client says.
Affirming therapy approaches with children involve “tuning into” their preferred way of communicating, playing and engaging. This can bring meaningful connection rather than compliance to “neurotypical” ways of playing and relating.
In workplaces, it can involve flexible working arrangements (hours, patterns and locations), allowing different modes of communication (such as written rather than phone calls) and low-sensory workspaces (for example, low-lighting, low-noise office spaces).
In public spaces, it can look like providing a “sensory space”, such as at large concerts, where neurodivergent people can take a break and self-regulate if needed. And staff can be trained to recognise, better understand and assist with hidden disabilities.
Combining lived experience and good practice
Care is neuroaffirmative when it centres “lived experience” in its design and delivery, and positions people with disability as experts.
As a result of being “different”, people in the neurodivergent community experience high rates of bullying and abuse. So neuroaffirming care should be combined with a trauma-informed approach, which acknowledges the need to understand a person’s life experiences to provide effective care.
Culturally responsive care acknowledges limited access to support for culturally and racially marginalised Autistic people and higher rates of LGBTQIA+ identification in the neurodivergent community.
In the workplace, we can acknowledge how difference can fuel ideas. Unsplash/Jason Goodman Authentic selves
The draft National Autism Strategy promotes awareness that our population is neurodiverse. It hopes to foster a more inclusive and understanding society.
It emphasises the societal and public health responsibilities for supporting neurodivergent people via public education, training, policy and legislation. By providing spaces and places where neurodivergent people can be their authentic, unmasked selves, we are laying the foundations for feeling seen, valued, safe and, ultimately, happy and thriving.
