What Omega-3 Fatty Acids Really Do For Us

Shockingly, we’ve not previously covered this in a main feature here at 10almonds… Mostly we tend to focus on less well-known supplements. However, in this case, the supplement may be well known, while some of its benefits, we suspect, may come as a surprise.

So…

What is it?

In this case, it’s more of a “what are they?”, because omega-3 fatty acids come in multiple forms, most notably:

  • Alpha-linoleic acid (ALA)
  • Eicosapentaenoic acid (EPA)
  • Docosahexanoic acid (DHA)

ALA is most readily found in certain seeds and nuts (chia seeds and walnuts are top contenders), while EPA and DHA are most readily found in certain fish (hence “cod liver oil” being a commonly available supplement, though actually cod aren’t even the best source—salmon and mackerel are better; cod is just cheaper to overfish, making it the cheaper supplement to manufacture).

Which of the three is best, or do we need them all?

There are two ways of looking at this:

  • ALA is sufficient alone, because it is a precursor to EPA and DHA, meaning that the body will take ALA and convert it into EPA and DHA as required
  • EPA and DHA are superior because they’re already in the forms the body will use, which makes them more efficient

As with most things in health, diversity is good, so you really can’t go wrong by getting some from each source.

Unless you have an allergy to fish or nuts, in which case, definitely avoid those!

What do omega-3 fatty acids do for us, according to actual research?

Against inflammation

Most people know it’s good for joints, as this is perhaps what it’s most marketed for. Indeed, it’s good against inflammation of the joints (and elsewhere), and autoimmune diseases in general. So this means it is indeed good against common forms of arthritis, amongst others:

Against menstrual pain

Linked to the above-referenced anti-inflammatory effects, omega-3s were also found to be better than ibuprofen for the treatment of severe menstrual pain:

Against cognitive decline

This one’s a heavy-hitter. It’s perhaps to be expected of something so good against inflammation (bearing in mind that, for example, a large part of Alzheimer’s is effectively a form of inflammation of the brain); as this one’s so important and such a clear benefit, here are three particularly illustrative studies:

Against heart disease

The title says it all in this one:

A meta-analysis shows that docosahexaenoic acid from algal oil reduces serum triglycerides and increases HDL-cholesterol and LDL-cholesterol in persons without coronary heart disease

But what about in patients who do have heart disease?

Mozaffarian and Wu did a huge meta-review of available evidence, and found that in fact, of all the studied heart-related effects, reducing mortality rate in cases of cardiovascular disease was the single most well-evidenced benefit:

How much should we take?

There’s quite a bit of science on this, and—which is unusual for something so well-studied—not a lot of consensus.

However, to summarize the position of the academy of nutrition and dietetics on dietary fatty acids for healthy adults, they recommend a minimum of 250–500 mg combined EPA and DHA each day for healthy adults. This can be obtained from about 8 ounces (230g) of fatty fish per week, for example.

If going for ALA, on the other hand, the recommendation becomes 1.1g/day for women or 1.6g/day for men.

  • How to Fall Back Asleep After Waking Up in the Middle of the Night

    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. Michael Bruce, the Sleep Doctor, addresses a common concern: waking up in the middle of the night and struggling to fall back asleep.

    Understanding the Wake-Up

    Firstly, why are we waking up during the night?

    Waking up between 2 AM and 3 AM is said to be normal, and linked to your core body temperature. As your body core temperature drops, to trigger melatonin release, and then rises again, you get into a lighter stage of sleep. This lighter stage of sleep makes you more prone to waking up.

    Note, there are also some medical conditions (such as sleep apnea) that can cause you to wake up during the night.

    But, what can we do about it? Aside from constantly shifting sleeping position (Should I be sleeping on my back? On my left? Right?)

    Avoid the Clock

    The first step is to resist the urge to check the time. It’s easy to be tempted to have a look at the clock, however, doing so can increase anxiety, making it harder to fall back asleep. As Dr. Bruce says, sleep is like love—the less you chase it, the more it comes.

    It may be useful to point your alarm clock (if you still have one of those) the opposite direction to your bed.

    Embracing Non-Sleep Deep Rest (NSDR)

    Whilst this may not help you fall back asleep, it’s worth pointing out that just lying quietly in the dark without moving still offers rejuvenation. This revujenating stage is called Non-Sleep Deep Rest (otherwise known as NSDR)

    If you’re not familiar with NSDR, check out our overview of Andrew Huberman’s opinions on NSDR here.

    So, you can reassure yourself that whilst you may not be asleep, you are still resting.

    Keep Your Heart Rate Down

    To fall back asleep, it’s best if your heart rate is below 60 bpm. So, Dr. Bruce advises avoiding void getting up unnecessarily, as moving around can elevate your heart rate.

    On a similar vain, he introduces the 4-7-8 breathing technique, which is designed to lower your heart rate. The technique is simple:

    • Breathe in for 4 seconds.
    • Hold for 7 seconds.
    • Exhale for 8 seconds.

    Repeat this cycle gently to calm your body and mind.

  • Purpose – by Gina Bianchini

    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.

    To address the elephant in the room, this is not a rehash of Rick Warren’s best-selling “The Purpose-Driven Life”. Instead, this book is (in this reviewer’s opinion) a lot better. It’s a lot more comprehensive, and it doesn’t assume that what’s most important to the author will be what’s most important to you.

    What’s it about, then? It’s about giving your passion (whatever it may be) the tools to have an enduring impact on the world. It recommends doing this by leveraging a technology that would once have been considered magic: social media.

    Far from “grow your brand” business books, this one looks at what really matters the most to you. Nobody will look back on your life and say “what a profitable second quarter that was in such-a-year”. But if you do your thing well, people will look back and say:

    • “he was a pillar of the community”
    • “she raised that community around her”
    • “they did so much for us”
    • “finding my place in that community changed my life”
    • …and so forth. Isn’t that something worth doing?

    Bianchini takes the position of both “idealistic dreamer” and “realistic worker”.

    Further, she blends the two beautifully, to give practical step-by-step instructions on how to give life to the community that you build.

  • Bright Line Eating – by Dr. Susan Peirce Thompson

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    This is a great title! It’s a great book too, but let’s talk about the title for a moment:

    The “Bright Line” referenced (often used in the plural within the book) is the line one draws between what one will and will not do. It’s a line one doesn’t cross, and it’s a bright line, because it’s not a case of “oh woe is me I cannot have the thing”, but rather “oh yay is me for I being joyously healthy”.

    And as for living happy, thin, and free? The author makes clear that “thin” is only a laudable goal if it’s bookended by “happy” and “free”. Eating things because we want to, and being happy about our choices.

    To this end, while some of the book is about nutrition (and for example the strong recommendation to make the first “bright lines” one draws cutting out sugar and flour), the majority of it is about the psychology of eating.

    This includes, hunger and satiety, willpower and lack thereof, disordered eating and addictions, body image issues and social considerations, the works. She realizes and explains, that if being healthy were just a matter of the right diet plan, everyone would be healthy. But it’s not; our eating behaviors don’t exist in a vacuum, and there’s a lot more to consider.

    Despite all the odds, however, this is a cheerful and uplifting book throughout, while dispensing very practical, well-evidenced methods for getting your brain to get your body to do what you want it to.

    Bottom line: this isn’t your average diet book, and it’s not just a motivational pep talk either. It’s an enjoyable read that’s also full of science and can make a huge difference to how you see food.

  • Knitting helps Tom Daley switch off. Its mental health benefits are not just for Olympians

    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.

    Olympian Tom Daley is the most decorated diver in Britain’s history. He is also an avid knitter. At the Paris 2024 Olympics Daley added a fifth medal to his collection – and caught the world’s attention knitting a bright blue “Paris 24” jumper while travelling to the games and in the stands.

    At the Tokyo Olympics, where Daley was first spotted knitting, he explained its positive impact on his mental health.

    It just turned into my mindfulness, my meditation, my calm and my way to escape the stresses of everyday life and, in particular, going to an Olympics.

    The mental health benefits of knitting are well established. So why is someone famous like Daley knitting in public still so surprising?

    Knitting is gendered

    Knitting is usually associated with women – especially older women – as a hobby done at home. In a large international survey of knitting, 99% of respondents identified as female.

    But the history of yarn crafts and gender is more tangled. In Europe in the middle ages, knitting guilds were exclusive and reserved for men. They were part of a respected Europe-wide trade addressing a demand for knitted products that could not be satisfied by domestic workers alone.

    The industrial revolution made the production of clothed goods cheaper and faster than hand-knitting. Knitting and other needle crafts became a leisure activity for women, done in the private sphere of the home.

    World Wars I and II turned the spotlight back on knitting as a “patriotic duty”, but it was still largely taken up by women.

    During COVID lockdowns, knitting saw another resurgence. But knitting still most often makes headlines when men – especially famous men like Daley or actor Ryan Gosling – do it.

    Men who knit are often seen as subverting the stereotype it’s an activity for older women.

    Knitting the stress away

    Knitting can produce a sense of pride and accomplishment. But for an elite sportsperson like Daley – whose accomplishments already include four gold medals and one silver – its benefits lie elsewhere.

    Olympics-level sport relies on perfect scores and world records. When it comes to knitting, many of the mental health benefits are associated with the process, rather than the end result.

    Daley says knitting is the “one thing” that allows him to switch off completely, describing it as “my therapy”. https://www.youtube.com/embed/6wwXGOki–c?wmode=transparent&start=0

    The Olympian says he could

    knit for hours on end, honestly. There’s something that’s so satisfying to me about just having that rhythm and that little “click-clack” of the knitting needles. There is not a day that goes by where I don’t knit.

    Knitting can create a “flow” state through rhythmic, repetitive movements of the yarn and needle. Flow offers us a balance between challenge, accessibility and a sense of control.

    It’s been shown to have benefits relieving stress in high-pressure jobs beyond elite sport. Among surgeons, knitting has been found to improve wellbeing as well as manual dexterity, crucial to their role.

    For other health professionals – including oncology nurses and mental health workers – knitting has helped to reduce “compassion fatigue” and burnout. Participants described the soothing noise of their knitting needles. They developed and strengthened team bonds through collective knitting practices. https://www.youtube.com/embed/dTTJjD_q2Ik?wmode=transparent&start=0 A Swiss psychiatrist says for those with trauma, knitting yarn can be like “knitting the two halves” of the brain “back together”.

    Another study showed knitting in primary school may boost children’s executive function. That includes the ability to pay attention, remember relevant details and block out distractions.

    As a regular creative practice, it has also been used in the treatment of grief, depression and subduing intrusive thoughts, as well countering chronic pain and cognitive decline.

    Knitting is a community

    The evidence for the benefits of knitting is often based on self-reporting. These studies tend to produce consistent results and involve large population samples.

    This may point to another benefit of knitting: its social aspect.

    Knitting and other yarn crafts can be done alone, and usually require simple materials. But they also provide a chance to socialise by bringing people together around a common interest, which can help reduce loneliness.

    The free needle craft database and social network Ravelry contains more than one million patterns, contributed by users. “Yarn bombing” projects aim to engage the community and beautify public places by covering objects such as benches and stop signs with wool.

    The interest in Daley’s knitting online videos have formed a community of their own.

    In them he shows the process of making the jumper, not just the finished product. That includes where he “went wrong” and had to unwind his work.

    His pride in the finished product – a little bit wonky, but “made with love” – can be a refreshing antidote to the flawless achievements often on display at the Olympics.

  • 8 Signs Of Iodine Deficiency You Might Not Expect

    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.

    Health Coach Kait (BSc Nutrition & Exercise) is a certified health and nutrition coach, and today she’s here to talk about iodine—which is important for many of our body functions, from thyroid hormone production to metabolic regulation to heart rate management, as well as more superficial-but-important-too things like our skin and hair.

    Kait’s hitlist

    Here’s what she recommends we look out for:

    • Swollen neck: even a slightly swollen neck might indicate low iodine levels (this is because that’s where the thyroid glands are)
    • Hair loss: iodine is needed for healthy hair growth, so a deficiency can lead to hair loss / thinning hair
    • Dry and flaky skin: with iodine’s role in our homeostatic system not being covered, our skin can dry out as a result
    • Feeling cold all the time: because of iodine’s temperature-regulating activities
    • Slow heart rate: A metabolic slump due to iodine deficiency can slow down the heart rate, leading to fatigue and weakness (and worse, if it persists)
    • Brain fog: trouble focusing can be a symptom of the same metabolic slump
    • Fatigue: this is again more or less the same thing, but she said eight signs, so we’re giving you the eight!
    • Irregular period (if you normally have such, of course): because iodine affects reproductive hormones too, an imbalance can disrupt menstrual cycles.

  • The Diabetes Code – by Dr. Jason Fung

    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.

    Cure this serious disease with diet!” is often a bold-claim that overreaches scientific rigor, but in this case, it’s well-established as scientifically valid.

    Caveat up-front: the only known circumstance in which this won’t work is if you have comorbidities that prevent you from following the advice.

    You may be wondering: is this just the Mediterranean diet again? The answer is that the Mediterreanean diet (or similar) is part of it. But there’s a lot more to this book than that.

    Dr. Fung explains to us a lot of the physiology of type 2 diabetes; how insulin resistance occurs, how it becomes a vicious cycle that we get locked into, and how to escape it.

    • We learn about the role of fructose, and why fruit is very healthful whereas high-fructose corn syrup and similars are very much not.
    • We learn about the role of the liver in glycogen metabolism, and how to un-fatty a fatty liver. Good news: the liver has famously strong self-regenerative abilities, if we give it a break to allow it to do so!
    • We learn why portion control doesn’t work, and why intermittent fasting does (here be science).

    Dr. Fung’s very readable explanations are free from needless jargon while not dumbing down. The writing style is clear and direct: “this happens this way”, “do this, not that”, etc.

    Bottom line: if you have type 2 diabetes and would like to not have that (or if you are pre-diabetic and would like to avoid diabetes) this is a book for you. If you are in great metabolic health and would like to stay that way as you get older, then this is a book for you too.
