Q: Why is your newsletter called 10almonds? Maybe I missed it in the intro email, but my curiosity wants to know the significance. Thanks!”

It’s a reference to a viral Facebook hoax! There was a post going around that claimed:

❝HEADACHE REMEDY. Eat 10–12 almonds, the equivalent of two aspirins, next time you have a headache❞ ← not true!

It made us think about how much health-related disinformation there was online… So, calling ourselves 10almonds was a bit of a tongue-in-cheek reference to that story… but also a reminder to ourselves:

We must always publish information with good scientific evidence behind it!

  • How To Build a Body That Lasts – by Adam Richardson

    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 book is written on a premise, and that premise is: “your age doesn’t define your mobility; your mobility defines your age”.

    To this end, we are treated to 328 pages of why and how to improve our mobility (mostly how; just enough on the “why” to keep the motivation flowing).

    Importantly, Richardson doesn’t expect that every reader is a regular gym-bunny or about to become one, doesn’t expect you to have several times your bodyweight in iron to life at home, and doesn’t expect that you’ll be doing the vertical splits against a wall any time soon.

    Rather, he expects that we’d like to not dislocate a shoulder while putting the groceries away, would like to not slip a disk while being greeted by the neighbor’s dog, and would like to not need a 7-step plan for putting our socks on.

    What follows is a guide to “on the good end of normal” mobility that is sustainable for life. The idea is that you might not be winning Olympic gymnastics gold medals in your 90s, but you will be able to get in and out of a car door as comfortably as you did when you were 20, for example.

    Bottom line: if you want to be a superathlete, then you might need something more than this book; if you want to be on the healthy end of average when it comes to mobility, and maintain that for the rest of your life, then this is the book for you.

  • Do you have knee pain from osteoarthritis? You might not need surgery. Here’s what to try instead

    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.

    Most people with knee osteoarthritis can control their pain and improve their mobility without surgery, according to updated treatment guidelines from the Australian Commission on Safety and Quality in Health Care.

    So what is knee osteoarthritis and what are the best ways to manage it?

    Pexels/Kindelmedia

    More than 2 million Australians have osteoarthritis

    Osteoarthritis is the most common joint disease, affecting 2.1 million Australians. It costs the economy A$4.3 billion each year.

    Osteoarthritis commonly affects the knees, but can also affect the hips, spine, hands and feet. It impacts the whole joint including bone, cartilage, ligaments and muscles.

    Most people with osteoarthritis have persistent pain and find it difficult to perform simple daily tasks, such as walking and climbing stairs.

    Is it caused by ‘wear and tear’?

    Knee osteoarthritis is most likely to affect older people, those who are overweight or obese, and those with previous knee injuries. But contrary to popular belief, knee osteoarthritis is not caused by “wear and tear”.

    Research shows the degree of structural wear and tear visible in the knee joint on an X-ray does not correlate with the level of pain or disability a person experiences. Some people have a low degree of structural wear and tear and very bad symptoms, while others have a high degree of structural wear and tear and minimal symptoms. So X-rays are not required to diagnose knee osteoarthritis or guide treatment decisions.

    Telling people they have wear and tear can make them worried about their condition and afraid of damaging their joint. It can also encourage them to try invasive and potentially unnecessary treatments such as surgery. We have shown this in people with osteoarthritis, and other common pain conditions such as back and shoulder pain.

    This has led to a global call for a change in the way we think and communicate about osteoarthritis.

    What’s the best way to manage osteoarthritis?

    Non-surgical treatments work well for most people with osteoarthritis, regardless of their age or the severity of their symptoms. These include education and self-management, exercise and physical activity, weight management and nutrition, and certain pain medicines.

    Education is important to dispel misconceptions about knee osteoarthritis. This includes information about what osteoarthritis is, how it is diagnosed, its prognosis, and the most effective ways to self-manage symptoms.

    Health professionals who use positive and reassuring language can improve people’s knowledge and beliefs about osteoarthritis and its management.

    Many people believe that exercise and physical activity will cause further damage to their joint. But it’s safe and can reduce pain and disability. Exercise has fewer side effects than commonly used pain medicines such as paracetamol and anti-inflammatories and can prevent or delay the need for joint replacement surgery in the future.

    Many types of exercise are effective for knee osteoarthritis, such as strength training, aerobic exercises like walking or cycling, Yoga and Tai chi. So you can do whatever type of exercise best suits you.

    Increasing general physical activity is also important, such as taking more steps throughout the day and reducing sedentary time.

    Weight management is important for those who are overweight or obese. Weight loss can reduce knee pain and disability, particularly when combined with exercise. Losing as little as 5–10% of your body weight can be beneficial.

    Pain medicines should not replace treatments such as exercise and weight management but can be used alongside these treatments to help manage pain. Recommended medicines include paracetamol and non-steroidal anti-inflammatory drugs.

    Opioids are not recommended. The risk of harm outweighs any potential benefits.

    What about surgery?

    People with knee osteoarthritis commonly undergo two types of surgery: knee arthroscopy and knee replacement.

    Knee arthroscopy is a type of keyhole surgery used to remove or repair damaged pieces of bone or cartilage that are thought to cause pain.

    However, high-quality research has shown arthroscopy is not effective. Arthroscopy should therefore not be used in the management of knee osteoarthritis.

    Joint replacement involves replacing the joint surfaces with artificial parts. In 2021–22, 53,500 Australians had a knee replacement for their osteoarthritis.

    Joint replacement is often seen as being inevitable and “necessary”. But most people can effectively manage their symptoms through exercise, physical activity and weight management.

    The new guidelines (known as “care standard”) recommend joint replacement surgery only be considered for those with severe symptoms who have already tried non-surgical treatments.

    I have knee osteoarthritis. What should I do?

    The care standard links to free evidence-based resources to support people with osteoarthritis. These include:

    If you have osteoarthritis, you can use the care standard to inform discussions with your health-care provider, and to make informed decisions about your care.

  • Reading At Night: Good Or Bad For Sleep? And Other Questions

    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 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

    ❝Would be interested in your views about “reading yourself to sleep”. I find that current affairs magazines and even modern novels do exactly the opposite. But Dickens – ones like David Copperfield and Great Expectations – I find wonderfully effective. It’s like entering a parallel universe where none of your own concerns matter. Any thoughts on the science that may explain this?!❞

    Anecdotally: this writer is (like most writers) a prolific reader, and finds reading some fiction last thing at night is a good way to create a buffer between the affairs of the day and the dreams of night—but I could never fall asleep that way, unless I were truly sleep-deprived. The only danger is if I “one more chapter” my way deep into the night! For what it’s worth, bedtime reading for me means a Kindle self-backlit with low, soft lighting.

    Scientifically: this hasn’t been a hugely researched area, but there are studies to work from. But there are two questions at hand (at least) here:

    1. one is about reading, and
    2. the other is about reading from electronic devices with or without blue light filters.

    Here’s a study that didn’t ask the medium of the book, and concluded that reading a book in bed before going to sleep improved sleep quality, compared to not reading a book in bed:

    Does reading a book in bed make a difference to sleep in comparison to not reading a book in bed? The People’s Trial-an online, pragmatic, randomised trial

    Here’s a study that concluded that reading on an iPad (with no blue light filter) that found no difference in any metrics except EEG (so, there was no difference on time spent in different sleep states or sleep onset latency), but advised against it anyway because of the EEG readings (which showed slow wave activity being delayed by approximately 30 minutes, which is consistent with melatonin production mechanics):

    Reading from an iPad or from a book in bed: the impact on human sleep. A randomized controlled crossover trial

    Here’s another study that didn’t take EEG readings, and/but otherwise confirmed no differences being found:

    Two hours of evening reading on a self-luminous tablet vs. reading a physical book does not alter sleep after daytime bright light exposure

    We’re aware this goes against general “sleep hygiene” advice in two different ways:

    • General advice is to avoid electronic devices before bedtime
    • General advice is to not do activities besides sleep (and sex) in bed

    …but, we’re committed to reporting the science as we find it!

    Enjoy!

  • Strength training has a range of benefits for women. Here are 4 ways to get into weights

    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.

    Picture a gym ten years ago: the weights room was largely a male-dominated space, with women mostly doing cardio exercise. Fast-forward to today and you’re likely to see women of all ages and backgrounds confidently navigating weights equipment.

    This is more than just anecdotal. According to data from the Australian Sports Commission, the number of women participating in weightlifting (either competitively or not) grew nearly five-fold between 2016 and 2022.

    Women are discovering what research has long shown: strength training offers benefits beyond sculpted muscles.

    Health benefits

    Osteoporosis, a disease in which the bones become weak and brittle, affects more women than men. Strength training increases bone density, a crucial factor for preventing osteoporosis, especially for women negotiating menopause.

    Strength training also improves insulin sensitivity, which means your body gets better at using insulin to manage blood sugar levels, reducing the risk of type 2 diabetes. Regular strength training contributes to better heart health too.

    There’s a mental health boost as well. Strength training has been linked to reduced symptoms of depression and anxiety.

    Improved confidence and body image

    Unlike some forms of exercise where progress can feel elusive, strength training offers clear and tangible measures of success. Each time you add more weight to a bar, you are reminded of your ability to meet your goals and conquer challenges.

    This sense of achievement doesn’t just stay in the gym – it can change how women see themselves. A recent study found women who regularly lift weights often feel more empowered to make positive changes in their lives and feel ready to face life’s challenges outside the gym.

    Strength training also has the potential to positively impact body image. In a world where women are often judged on appearance, lifting weights can shift the focus to function.

    Instead of worrying about the number on the scale or fitting into a certain dress size, women often come to appreciate their bodies for what they can do. “Am I lifting more than I could last month?” and “can I carry all my groceries in a single trip?” may become new measures of physical success.

    Lifting weights can also be about challenging outdated ideas of how women “should” be. Qualitative research I conducted with colleagues found that, for many women, strength training becomes a powerful form of rebellion against unrealistic beauty standards. As one participant told us:

    I wanted something that would allow me to train that just didn’t have anything to do with how I looked.

    Society has long told women to be small, quiet and not take up space. But when a woman steps up to a barbell, she’s pushing back against these outdated rules. One woman in our study said:

    We don’t have to […] look a certain way, or […] be scared that we can lift heavier weights than some men. Why should we?

    This shift in mindset helps women see themselves differently. Instead of worrying about being objects for others to look at, they begin to see their bodies as capable and strong. Another participant explained:

    Powerlifting changed my life. It made me see myself, or my body. My body wasn’t my value, it was the vehicle that I was in to execute whatever it was that I was executing in life.

    This newfound confidence often spills over into other areas of life. As one woman said:

    I love being a strong woman. It’s like going against the grain, and it empowers me. When I’m physically strong, everything in the world seems lighter.

    Feeling inspired? Here’s how to get started

    1. Take things slow

    Begin with bodyweight exercises like squats, lunges and push-ups to build a foundation of strength. Once you’re comfortable, add external weights, but keep them light at first. Focus on mastering compound movements, such as deadlifts, squats and overhead presses. These exercises engage multiple joints and muscle groups simultaneously, making your workouts more efficient.

    2. Prioritise proper form

    Always prioritise proper form over lifting heavier weights. Poor technique can lead to injuries, so learning the correct way to perform each exercise is crucial. To help with this, consider working with an exercise professional who can provide personalised guidance and ensure you’re performing exercises correctly, at least initially.

    3. Consistency is key

    Like any fitness regimen, consistency is key. Two to three sessions a week are plenty for most women to see benefits. And don’t be afraid to occupy space in the weights room – remember you belong there just as much as anyone else.

    4. Find a community

    Finally, join a community. There’s nothing like being surrounded by a group of strong women to inspire and motivate you. Engaging with a supportive community can make your strength-training journey more enjoyable and rewarding, whether it’s an in-person class or an online forum.

    Are there any downsides?

    Gym memberships can be expensive, especially for specialist weightlifting gyms. Home equipment is an option, but quality barbells and weightlifting equipment can come with a hefty price tag.

    Also, for women juggling work and family responsibilities, finding time to get to the gym two to three times per week can be challenging.

    If you’re concerned about getting too “bulky”, it’s very difficult for women to bulk up like male bodybuilders without pharmaceutical assistance.

    The main risks come from poor technique or trying to lift too much too soon – issues that can be easily avoided with some guidance.

  • How To Rest More Efficiently (Yes, Really)

    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.

    How To Rest More Efficiently (Yes, Really)

    We’ve talked before about how to recover more quickly after a workout, especially if you overdid it. There are a lot of tips in that article, so by all means check it out if you didn’t catch it at the time!

    That was very specific to recovering from exercise, though. Today we’re looking at something a little different, a little more holistic.

    You’re busier than you think

    Maybe your life is an obvious blur of busy-ness. Maybe it’s not. But either way, you’re almost certainly busier than you think. Especially on a cellular level.

    Your resting metabolic rate (RMR), or how many calories you burn while at rest (i.e., calories used just to keep you alive) will depend on various factors including age, sex, weight, body composition, and other things.

    That said, it’ll probably be between 1000 and 2000 calories per day. You can get a rough idea of what it might be for you, using this calculator:

    How Many Calories Do You Burn a Day at Rest (Doing Nothing)?

    So if ever you wonder why you feel so exhausted, despite having done nothing, it could be that your body was busy:

    • Metabolizing, generally (did you have a big meal?)
    • Fighting an illness (bacterial or viral infection, for example)
    • Fighting an imaginary illness and creating a real one in the process (stress, inflammation, etc)
    • Recovering/rebuilding from something you did yesterday or even before that
    • Thinking (your brain is your largest organ by mass, and consumes the most calories by far)

    Your brain does not get a free pass on being part of your body! Just like if a certain muscle group were working out constantly for 16 hours you’d be feeling pretty tired, the same goes for the organ that is your brain, if it’s been working out constantly.

    Your body is a composite organism—take advantage of that

    Dolphins can shut down half of their brain at once, to let each hemisphere of the brain sleep independently in shifts. We (except in the case of split brain patients, where the corpus callosum has been severed) can’t do that, but we can let different parts of the organism that is our body work in shifts.

    This is the real meaning of “a change is as a good as a rest”:

    If you’ve been doing cognitive work (at your desk perhaps, maybe managing a spreadsheet, say), then taking a break to do crosswords will not, actually, give you break. Because you’re still sitting manipulating letters and numbers. As far as your brain (still having to do work!) is concerned, it’s basically the same. Nor will checking out social media; you’re still sitting examining a screen.

    Instead, time to get physically active. Literally just doing the washing up would be a better break! Some yoga or Pilates would be perfect.

    In contrast, if you’ve been doing a vigorous bit of gardening, then for example taking a break to lift weights isn’t going to be a break, because again you just switched to a similar task.

    Better to pick up that book you’ve been meaning to read, or the crosswords we mentioned earlier. Or just lounge in your nicely-gardened garden.

    The important thing is: to not require the same resources from the body (including the brain, it’s still part of the body) that you have been.

    For more specific tips than we have room for here today, check out:

    How to Take Better Breaks at Work, According to Research

    Give your metabolism a break too

    Not completely—you don’t need to be put into cryostasis or anything.

    But, give your metabolism a rest, in relative terms. Intermittent fasting is great for precisely this; it lets your body rest and reset.

    See: Intermittent Fasting: we sort the science from the hype!

    So does the practice of meditation, by the way. You don’t have to get fancy with it, either:

  • Apple Cider Vinegar vs Balsamic Vinegar – 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 apple cider vinegar to balsamic vinegar, we picked the apple cider vinegar.

    Why?

    It’s close! And it’s a simple one today and they’re both great. Taking either for blood-sugar-balancing benefits is fine, as it’s the acidity that has this effect. But:

    • Of the two, balsamic vinegar is the one more likely to contain more sugars, especially if it’s been treated in any fashion, and not by you, e.g. made into a glaze or even a reduction (the latter has no need to add sugar, but sometimes companies do because it is cheaper—so we recommend making your own balsamic vinegar reduction at home)
    • Of the two, apple cider vinegar is the one more likely to contain “the mother”, that is to say, the part with extra probiotic benefits (but if the vinegar has been filtered, it won’t have this—it’s just more common to be able to find unfiltered apple cider vinegar, since it has more popular attention for its health benefits than balsamic vinegar does)

    So, two wins for apple cider vinegar there.
