This book’s blurb contains a bold claim:
❝If you want to fix your sleep problems, Internet tips and tricks aren’t going to do it for you. You need to really understand what’s going on with your sleep—both what your problems are and how to solve them.❞
So, how well does it deliver, on the strength of being a whole book rather than an Internet article?
Well, for sure we wouldn’t have the room to include all the information that Dr. Winter does, in one of our main feature articles here (we’d need to spread it out over several weeks, at least).
He examines very thoroughly what is going on with sleep, sleep disturbance, and sleep deprivation. What’s going on with the different phases of sleep (far more than your phone’s sleep app will), and how imbalances in these can cause problems.
While the usual sleep hygiene tips do get a mention, he broadly assumes we know that part already. Instead, he focuses on aligning as many components as possible of our rich and interesting circadian rhythm. Yes, even if that means clawing our way out of insomnia and/or a bad sleep schedule (or lack of coherent sleep schedule) first. He gives plenty of practical advice on how to do that.
Bottom line: if you’d like to more deeply understand sleep, what is or isn’t wrong with yours, and how you can fix it, this book is a great resource.

I’m iron deficient. Which supplements will work best for me and how should I take them?
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.
Iron deficiency is common and can be debilitating. It mainly affects women. One in three premenopausal women are low in iron compared to just 5% of Australian men. Iron deficiency particularly affects teenage girls, women who do a lot of exercise and those who are pregnant.
The body needs iron to make new red blood cells, and to support energy production, the immune system and cognitive function. If you’re low, you may experience a range of symptoms including fatigue, weakness, shortness of breath, headache, irregular heartbeat and reduced concentration.
If a blood test shows you’re iron deficient, your doctor may recommend you start taking an oral iron supplement. But should you take a tablet or a liquid? With food or not? And when is the best time of day?
Here are some tips to help you work out how, when and what iron supplement to take.
How do I pick the right iron supplement?
The iron in your body is called “elemental iron”. Choosing the right oral supplement and dose will depend on how much elemental iron it has – your doctor will advise exactly how much you need.
The sweet spot is between 60-120 mg of elemental iron. Any less and the supplement won’t be effective in topping up your iron levels. Any higher and you risk gastrointestinal symptoms such as diarrhoea, cramping and stomach pain.
In Australia, iron salts are the most common oral supplements because they are cheap, effective and come in different delivery methods (tablets, capsules, liquid formulas). The iron salts you are most likely to find in your local chemist are ferrous sulfate (~20% elemental iron), ferrous gluconate (~12%) and ferrous fumarate (~33%).
These formulations all work similarly, so your choice should come down to dose and cost.
Many multivitamins may look like an iron supplement, but it’s important to note they usually have too little iron – usually less than 20 mg – to correct an iron deficiency.
Should I take tablets or liquid formulas?
Iron contained within a tablet is just as well absorbed as iron found in a liquid supplement. Choosing the right one usually comes down to personal preference.
The main difference is that liquid formulas tend to contain less iron than tablets. That means you might need to take more of the product to get the right dose, so using a liquid supplement could work out to be more expensive in the long term.
What should I eat with my iron supplement?
Research has shown you will absorb more of the iron in your supplement if you take it on an empty stomach. But this can cause more gastrointestinal issues, so might not be practical for everyone.
If you do take your supplement with meals, it’s important to think about what types of food will boost – rather than limit – iron absorption. For example, taking the supplement alongside vitamin C improves your body’s ability to absorb it.
Some supplements already contain vitamin C. Otherwise you could take the supplement along with a glass of orange juice, or other vitamin C-rich foods.
On the other hand, tea, coffee and calcium all decrease the body’s ability to absorb iron. So you should try to limit these close to the time you take your supplement.
Should I take my supplement in the morning or evening?
The best time of day to take your supplement is in the morning. The body can absorb significantly more iron earlier in the day, when concentrations of hepcidin (the main hormone that regulates iron) are at their lowest.
Exercise also affects the hormone that regulates iron. That means taking your iron supplement after exercising can limit your ability to absorb it. Taking your supplement in the hours following exercise will mean significantly poorer absorption, especially if you take it between two and five hours after you stop.
Our research has shown if you exercise every day, the best time to take your supplement is in the morning before training, or immediately after (within 30 minutes).
My supplements are upsetting my stomach. What should I do?
If you experience gastrointestinal side effects such as diarrhoea or cramps when you take iron supplements, you may want to consider taking your supplement every second day, rather than daily.
Taking a supplement every day is still the fastest way to restore your iron levels. But a recent study has shown taking the same total dose can be just as effective when it’s taken on alternate days. For example, taking a supplement every day for three months works as well as every second day for six months. This results in fewer side effects.
Oral iron supplements can be a cheap and easy way to correct an iron deficiency. But ensuring you are taking the right product, under the right conditions, is crucial for their success.
It’s also important to check your iron levels prior to commencing iron supplementation and do so only under medical advice. In large amounts, iron can be toxic, so you don’t want to be consuming additional iron if your body doesn’t need it.
If you think you may be low on iron, talk to your GP to find out your best options.

‘I can’t quite shut it off’: Prevalence of insomnia a growing concern for women
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.
Tasha Werner, 43, gets up at 3:30 a.m. twice a week for her part-time job at a fitness centre in Calgary. After a five-hour shift, she is back home by 9 a.m. to homeschool her two children, aged 9 and 12. The hardest part of her position – stay-at-home mom, homeschool teacher and part-time worker – is the downtime “lost from my life,” says Werner.
A study by Howard M. Kravitz, a psychiatrist in Chicago, showed that up to 60 per cent of women experience sleep disorders due to hormonal changes linked to menopause. But there is an increasing prevalence of insomnia symptoms in women that may be attributed, in part, to societal changes.
“We live in a world that didn’t exist a generation ago. Now everyone is trying to figure it out,” says Michael Grandner, director of the Sleep and Health Research Program at the University of Arizona.
While women are no longer expected to stay at home, many who are employed outside the home also have the primary responsibility for family matters. And women aged 40 to 60 commonly fall within the “sandwich generation,” caring for both children and parents.
As women juggle their responsibilities, these duties can take a toll, both emotionally and practically.
Both Werner and her husband were raised in traditional homes; their mothers stayed at home to oversee childcare, cooking, grocery shopping and household duties. Initially, Werner and her husband followed a similar path, mirroring their parents’ lives as homemakers. “I think we just fell into what we were used to,” says Werner.
However, a notable shift in their family dynamics occurred once she started working outside the home.
Her children’s physical needs and illnesses have had major consequences on her sleep. If one of the children is sick with the flu, that’s “a week of not a lot of sleep during the night,” she says, “because that’s my job.” Many nights, she finds herself waking up between 1 a.m. and 3 a.m., worrying about how the kids are doing academically or behaviourally.
“We face a specific set of anxieties and a different set of pressures than men,” says Emma Kobil, who has been a therapist in Denver, Colo., for 15 years and is now an insomnia coach. There is so much pressure to be everything as a woman – to be an amazing homemaker and worker while maintaining a hot-rocking body and having a cool personality, to “be the cool mom but also the CEO, to follow your dreams and be the boss b****,” says Kobil.
And there’s an appeal to that concept. Daughters grow up viewing their moms as superwomen juggling responsibilities. But what isn’t always obvious are the challenges women face while managing their lives and the health issues they may encounter.
A study revealed that women are 41 per cent more at risk of insomnia than men.
A thorough study revealed that women are 41 per cent more at risk of insomnia than men. Beyond menopausal hormonal shifts, societal pressures, maternal concerns and the challenge of balancing multiple roles contribute to women’s increased susceptibility to insomnia.
Cyndi Aarrestad, 57, lives on a farm in Saskatchewan with her husband, Denis. Now an empty nester, Aarrestad fills her time working on the farm, keeping house, volunteering at her church and managing her small woodworking business. And she struggles with sleep.
Despite implementing some remedies, including stretching, drinking calming teas and rubbing her feet before bed, Aarrestad says achieving restful sleep has remained elusive for the past decade.
Two primary factors contribute to her sleep challenges — her inability to quiet her mind and hormonal hot flashes due to menopause. Faced with family and outside commitments, Aarrestad finds it challenging to escape night time’s mental chatter. “It’s a mom thing for me … I can’t quite shut it off.” Even as her children transitioned to young adulthood and moved out, the worries persisted, highlighting the lasting concerns moms have about their kids’ jobs, relationships and overall well-being.
Therapist Kobil says that every woman she’s ever worked with experiences this pressure to do everything, to be perfect. These women feel like they’re not measuring up. They’re encouraged to take on other people’s burdens; to be the confidante and the saviour in many ways; to sacrifice themselves. Sleep disruptions simply reflect the consequences of this pressure.
“They’re trying to fit 20 hours in a 24-hour day, and it doesn’t work,” says Grandner, the sleep specialist.
Grandner says that consistently sleeping six hours or less as an adult makes one 55 per cent more likely to become obese, 20 per cent more likely to develop high blood pressure, and 30 per cent more likely to develop Type 2 diabetes if you didn’t have it already. This lack of sleep makes you more likely to catch the flu. It makes vaccines less effective, and it increases your likelihood of developing depression and anxiety.
When is the time to change? Yesterday. Grandner warns that the sleep sacrifices made at a young age impact health later. But it’s never too late to make changes, he says, and “you do the best with what you’ve got.”
Kobil suggests a practical approach for women struggling with sleep. She emphasizes understanding that sleeplessness isn’t a threat and encourages a shift in mindset about being awake. Instead of fighting sleeplessness, she advises treating oneself kindly, recognizing the difficulty.
Kobil recommends creating a simple playbook with comforting activities for awake moments during the night. Just as you would comfort a child who’s afraid, she suggests being gentle with yourself, gradually changing the perception of wakefulness into a positive experience.

The Case Against Sugar – by Gary Taubes
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 generally already know that sugar is bad for the health. Most people don’t know how bad.
Taubes makes, as the title goes, “the case against sugar”. Implicated in everything from metabolic syndrome to cancer to Alzheimer’s, sugar is ruinous to the health.
It’s hard to review this book without making a comparison to William Duffy’s 1975 bestseller, “Sugar Blues“. Stylistically it’s very similar, and the general gist is certainly the same.
However! Where this book beats Sugar Blues is in content; Duffy’s book often makes bold claims without scientific backing. Some of those claims didn’t stand the test of time and are now disproven. Instead, Taubes’ book leans on actual up-to-date science, and talks more about what we actually know, than what we imagine.
If this book has a weak point, it’s when it veers away from its main topic and starts talking about, for example, saturated fat. In this side-topic, the book makes some good points, but is less well-considered, cherry-picks data, and lacks nuance.
On its main topic, though, the investigation of sugar, it is rather more thorough.
Bottom line: if you want a next-level motivation to reduce or eliminate dietary sugar, this book may certainly provide that.

No-Frills, Evidence-Based Mindfulness
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.
What’s on your mind, really?
We hear a lot about “the evidence-based benefits of mindfulness”, but what actually are they? And what is the evidence? And, perhaps most importantly: how do we do it?
What are the benefits?
The benefits of mindfulness are many, and include:
- reducing stress
- reducing pain
- improving quality of life
- reducing fatigue
- providing relief from digestive disorders
- reducing symptoms of sleep disorders
- improving immune response
- providing support for caregivers
The evidence is also abundant, and includes:
- Effects of mindfulness exercises as stand-alone intervention on symptoms of anxiety and depression: Systematic review and meta-analysis
- Fusing character strengths and mindfulness interventions: Benefits for satisfaction and performance
- Evidence for the Role of Mindfulness in Cancer: Benefits and Techniques
- Effects of mindfulness-based stress reduction on anxiety symptoms: A systematic review and meta-analysis
- The benefits of meditation and mindfulness practices during times of crisis such as COVID-19
Sounds great… What actually is it, though?
Mindfulness is the state of being attentive to one’s mind. This is at its heart a meditative practice, but that doesn’t necessarily mean you have to be sitting in the lotus position with candles—mindfulness can be built into any daily activity, or even no activity at all.
An exercise you can try right now:
Take a moment to notice everything you can hear. For this writer, that includes:
- The noise of my keystrokes as I type
- The ticking of the clock on the wall
- The gentle humming of my computer’s processor
- The higher-pitched noise of my computer’s monitor
- Birdsong outside
- Traffic further away
- My own breathing
- The sound of my eyelids as I blink
Whatever it is for you, notice how much you can notice that you had previously taken for granted.
You can repeat this exercise with other senses, by the way! For example:
- Notice five things you can see in your immediate environment that you’ve never noticed before. If you’re at home reading this, you probably think you’re very familiar with everything around you, but now see that mark on the wall you’d never noticed before, or a quirk of some electrical wiring, or the stitching on some furnishing, for example.
- Notice the textures of your clothes, or your face, or perhaps an object you’ve never paid attention to touching before. Your fingertips, unless you have some special reason this doesn’t apply to you, are far more sensitive than you probably give them credit for, and can notice the tiniest differentiation in textures, so take a moment to do that now.
- Mindful eating can be an especially healthful practice because it requires that we pay every attention to what we’re putting in our mouth, tasting, chewing, swallowing. No more thoughtlessly downing a box of cookies; every bite is now an experience. On the one hand, you’ll probably eat less at a sitting. On the other hand, what a sensory experience! It really reminds one that life is for living, not just for zipping through at a speed-run pace!
What about mindfulness as a meditative practice?
Well, those are meditative practices! But yes, mindfulness goes for more formal meditation too. For example:
Sit comfortably, with good posture, whatever that means to you. No need to get too caught up in the physical mechanics here—it’d take a whole article. For now, if you’re sitting and comfortable, that’s enough.
Notice your breathing. No need to try to control it—that’s not what this is about today. Just notice it. The in, the out, whether you breathe to your chest or abdomen, through your nose or mouth, don’t worry about doing it “right”, just notice what you are doing. Observe without judgement.
Notice your thoughts—no need to try to stop them. Notice noticing your thoughts, and again, observe without judgement. Notice your feelings; are you angry, hopeful, stressed, serene? There are no wrong answers here, and there’s nothing you should try to “correct”. Just observe. No judgement, only observe. Watch your thoughts, and watch your thoughts go.
Did you forget about your breathing while watching your thoughts? Don’t worry about that either if so, just notice that it happened. If you have any feelings about that, notice them too, and carry on observing.
We go through so much of our lives in “autopilot”, that it can be an amazing experience to sometimes just “be”—and be aware of being.

Which Sugars Are Healthier, And Which Are Just The Same?
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.
From Apples to Bees, and High-Fructose Cs
We asked you for your (health-related) policy on sugar. The trends were as follows:
- About half of all respondents voted for “I try to limit sugar intake, but struggle because it’s in everything”
- About a quarter of all respondents voted for “Refined sugar is terrible; natural sugars (e.g. honey, agave) are fine”
- About a quarter of all respondents voted for “Sugar is sugar and sugar is bad; I avoid it entirely”
- One (1) respondent voted for “Sugar is an important source of energy, so I consume plenty”
Writer’s note: I always forget to vote in these, but I’d have voted for “I try to limit sugar intake, but struggle because it’s in everything”.
Sometimes I would like to make my own [whatever] to not have the sugar, but it takes so much more time, and often money too.
So while I make most things from scratch (and typically spend about an hour cooking each day), sometimes store-bought is the regretfully practical timesaver/moneysaver (especially when it comes to condiments).
So, where does the science stand?
There has, of course, been a lot of research into the health impact of sugar.
Unfortunately, a lot of it has been funded by sugar companies, which has not helped. Conversely, there are also studies funded by other institutions with other agendas to push, and some of them will seek to make sugar out to be worse than it is.
So for today’s mythbusting overview, we’ve done our best to quality-control studies for not having financial conflicts of interest. And of course, the usual considerations of favoring high quality studies where possible Large sample sizes, good method, human subjects, that sort of thing.
Sugar is sugar and sugar is bad: True or False?
False and True, respectively.
- Sucrose is sucrose, and is generally bad.
- Fructose is fructose, and is worse.
Both ultimately get converted into glycogen (if not used immediately for energy), but for fructose, this happens mostly* in the liver, which a) taxes it b) goes very unregulated by the pancreas, causing potentially dangerous blood sugar spikes.
This has several interesting effects:
- Because fructose doesn’t directly affect insulin levels, it doesn’t cause insulin insensitivity (yay)
- Because fructose doesn’t directly affect insulin levels, this leaves hyperglycemia untreated (oh dear)
- Because fructose is metabolized by the liver and converted to glycogen which is stored there, it’s one of the main contributors to non-alcoholic fatty liver disease (at this point, we’re retracting our “yay”)
Read more: Fructose and sugar: a major mediator of non-alcoholic fatty liver disease
*”Mostly” in the liver being about 80% in the liver. The remaining 20%ish is processed by the kidneys, where it contributes to kidney stones instead. So, still not fabulous.
Fructose is very bad, so we shouldn’t eat too much fruit: True or False?
False! Fruit is really not the bad guy here. Fruit is good for you!
Fruit does contain fructose yes, but not actually that much in the grand scheme of things, and moreover, fruit contains (unless you have done something unnatural to it) plenty of fiber, which mitigates the impact of the fructose.
- A medium-sized apple (one of the most sugary fruits there is) might contain around 11g of fructose
- A tablespoon of high-fructose corn syrup can have about 27g of fructose (plus about 3g glucose)
Read more about it: Effects of high-fructose (90%) corn syrup on plasma glucose, insulin, and C-peptide in non-insulin-dependent diabetes mellitus and normal subjects
However! The fiber content (in fruit) mitigates the impact of the fructose almost entirely anyway.
And if you take fruits that are high in sugar and/but high in polyphenols, like berries, they now have a considerable net positive impact on glycemic health:
- Polyphenols and Glycemic Control
- Polyphenols and their effects on diabetes management: A review
- Dietary polyphenols as antidiabetic agents: Advances and opportunities
You may be wondering: what was that about “unless you have done something unnatural to it”?
That’s mostly about juicing. Juicing removes much (or all) of the fiber, and if you do that, you’re basically back to shooting fructose into your veins:
- Effect of Fruit Juice on Glucose Control and Insulin Sensitivity in Adults: A Meta-Analysis of 12 Randomized Controlled Trials
- Intake of Fruit, Vegetables, and Fruit Juices and Risk of Diabetes in Women
Natural sugars like honey, agave, and maple syrup, are healthier than refined sugars: True or False?
True… Sometimes, and sometimes marginally.
This is partly because of the glycemic index and glycemic load. The glycemic index scores tail off thus:
- table sugar = 65
- maple syrup = 54
- honey = 46
- agave syrup = 15
So, that’s a big difference there between agave syrup and maple syrup, for example… But it might not matter if you’re using a very small amount, which means it may have a high glycemic index but a low glycemic load.
Note, incidentally, that table sugar, sucrose, is a disaccharide, and is 50% glucose and 50% fructose.
The other more marginal health benefits come from that fact that natural sugars are usually found in foods high in other nutrients. Maple syrup is very high in manganese, for example, and also a fair source of other minerals.
But… Because of its GI, you really don’t want to be relying on it for your nutrients.
Wait, why is sugar bad again?
We’ve been covering mostly the more “mythbusting” aspects of different forms of sugar, rather than the less controversial harms it does, but let’s give at least a cursory nod to the health risks of sugar overall:
- Obesity and associated metabolic risk
- Main contributor to non-alcoholic fatty liver disease
- Increased risk of heart disease
- Insulin resistance and diabetes risk
- Cellular aging (shortened telomeres)
- 95% increased cancer risk
That last one, by the way, was a huge systematic review of 37 large longitudinal cohort studies. Results varied depending on what, specifically, was being examined (e.g. total sugar, fructose content, sugary beverages, etc), and gave up to 200% increased cancer risk in some studies on sugary beverages, but 95% increased risk is a respectable example figure to cite here, pertaining to added sugars in foods.

Buckwheat vs Oats – 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 buckwheat to oats, we picked the oats.
Why?
First of all, for any thinking about the health concerns sometimes associated with wheat: buckwheat is not a kind of wheat, nor is it even in the same family; it’s not a grain, but a flowering plant. Buckwheat is to wheat as a lionfish is to lions.
That said, while these are both excellent foods, one of them is so good it makes the other one look bad in comparison:
In terms of macros, oats have more carbs, but also more protein and more fiber.
When it comes to vitamins, a clear winner emerges: oats have more of vitamins B1, B2, B5, B6, and B9, while buckwheat is higher in vitamin K and choline.
In the category of minerals, things are even more pronounced: oats are higher in calcium, iron, magnesium, manganese, phosphorus, potassium, and zinc. On the other hand, buckwheat is higher in selenium.
All in all: as ever, enjoy both, but if you’re picking one, oats cannot be beaten.
