Dr. Rupy Aujla: The Kitchen Doctor

This is Dr. Rupy Aujla, and he’s a medical doctor. He didn’t set out to become a “health influencer”.

But then, a significant heart condition changed his life. Having a stronger motivation to learn more about nutritional medicine, he did a deep dive into the scientific literature, because that’s what you do when your life is on the line, especially if you’re a doctor!

Using what he learned, he was able to reverse his condition using a food and lifestyle approach. Now, he devotes himself to sharing what he learned—and what he continues to learn as he goes along.

One important thing he learned because of what happened to him, was that he hadn’t been paying enough attention to what his body was trying to tell him.

He wants us to know about interoception—which isn’t a Chris Nolan movie. Rather, interoception is the sense of what is going on inside one’s own body.

The counterpart of this is exteroception: our ability to perceive the outside world by means of our various senses.

Interoception is still using the senses, but is sensing internal body sensations. Effectively, the brain interprets and integrates what happens in our organs.

When interoception goes wrong, researchers found, it can lead to a greater likelihood of mental health problems. Having an anxiety disorder, depression, mood disorder, or an eating disorder often comes with difficulties in sensing what is going on inside the body.

Improving our awareness of body cues

Those same researchers suggested therapies and strategies aimed at improving awareness of mind-body connections. For example, mindfulness-based stress reduction, yoga, meditation and movement-based treatments. They could improve awareness of body cues by attending to sensations of breathing, cognitions and other body states.

But where Dr. Aujla puts his focus is “the heart of the home”, the kitchen.

The pleasure of food

❝Eating is not simply ingesting a mixture of nutrients. Otherwise, we would all be eating astronaut food. But food is not only a tool for health. It’s also an important pleasure in life, allowing us to connect to others, the present moment and nature.❞

Dr. Rupy Aujla

Dr. Aujla wants to help shift any idea of a separation between health and pleasure, because he believes in food as a positive route to well-being, joy and health. For him, it starts with self-awareness and acceptance of the sensory pleasures of eating and nourishing our bodies, instead of focusing externally on avoiding perceived temptations.

Most importantly:

We can use the pleasure of food as an ally to healthy eating.

Instead of spending our time and energy fighting the urge to eat unhealthy things that may present a “quick fix” to some cravings but aren’t what our body actually wants, needs, Dr. Aujla advises us to pay just a little more attention, to make sure the body’s real needs are met.

His top tips for such are:

  • Create an enjoyable relaxing eating environment

To help cultivate positive emotions around food and signal to the nervous system a shift to food-processing time. Try setting the table with nothing else on it beyond what’s relevant to the dinner, putting away distractions, using your favorite plates, tablecloth, etc.

  • Take 3 deep abdominal breaths before eating

To help you relax and ground yourself in the present moment, which in turn is to prepare your digestive system to receive and digest food.

  • Pay attention to the way you sit

Take some time to sit comfortably with your feet grounded on the floor, not slouching, to give your stomach space to digest the food.

  • Appreciate what it took to bring this food to your plate

Who was involved in the growing process and production, the weather and soil it took to grow the food, and where in the world it came from.

  • Enjoy the sensations

When you’re cooking, serving, and eating your food, be attentive to color, texture, aroma and even sound. Taste the individual ingredients and seasonings along the way, when safe and convenient to do so.

  • Journal

If you like journaling, you can try adding a mindful eating section to that. Ask questions such as: “how did I feel before, during, and after the meal?”

In closing…

Remember that this is a process, not only on an individual level but as a society too.

Oftentimes it’s hard to eat healthily… We can be given to wonder even “what is healthy, after all?”, and we can be limited by what is available, what is affordable, and what we have time to prepare.

But if we make a conscious commitment to make the best choices we reasonably can as we go along, then small changes can soon add up.

  • Women take more antidepressants after divorce than men but that doesn’t mean they’re more depressed

    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.

    Research out today from Finland suggests women may find it harder to adjust to later-life divorce and break-ups than men.

    The study used population data from 229,000 Finns aged 50 to 70 who had undergone divorce, relationship break-up or bereavement and tracked their use of antidepressants before and after their relationship ended.

    They found antidepressant use increased in the four years leading to the relationship dissolution in both genders, with women experiencing a more significant increase.

    But it’s too simplistic to say women experience poorer mental health or tend to be less happy after divorce than men.

    Remind me, how common is divorce?

    Just under 50,000 divorces are granted each year in Australia. This has slowly declined since the 1990s.

    More couple are choosing to co-habitate, instead of marry, and the majority of couples live together prior to marriage. Divorce statistics don’t include separations of cohabiting couples, even though they are more likely than married couples to separate.

    Those who divorce are doing so later in life, often after their children grow up. The median age of divorce increased from 45.9 in 2021 to 46.7 in 2022 for men and from 43.0 to 43.7 for women.

    The trend of late divorces also reflects people deciding to marry later in life. The median duration from marriage to divorce in 2022 was around 12.8 years and has remained fairly constant over the past decade.

    Why do couples get divorced?

    Changes in social attitudes towards marriage and relationships mean divorce is now more accepted. People are opting not to be in unhappy marriages, even if there are children involved.

    Instead, they’re turning the focus on marriage quality. This is particularly true for women who have established a career and are financially autonomous.

    Similarly, my research shows it’s particularly important for people to feel their relationship expectations can be fulfilled long term. In addition to relationship quality, participants reported needing trust, open communication, safety and acceptance from their partners.

    Grey divorce” (divorce at age 50 and older) is becoming increasingly common in Western countries, particularly among high-income populations. While factors such as an empty nest, retirement, or poor health are commonly cited predictors of later-in-life divorce, research shows older couples divorce for the same reasons as younger couples.

    What did the new study find?

    The study tracked antidepressant use in Finns aged 50 to 70 for four years before their relationship breakdown and four years after.

    They found antidepressant use increased in the four years leading to the relationship break-up in both genders. The proportion of women taking antidepressants in the lead up to divorce increased by 7%, compared with 5% for men. For de facto separation antidepressant use increased by 6% for women and 3.2% for men.

    Within a year of the break-up, antidepressant use fell back to the level it was 12 months before the break-up. It subsequently remained at that level among the men.

    But it was a different story for women. Their use tailed off only slightly immediately after the relationship breakdown but increased again from the first year onwards.

    Women’s antidepressant use increased again.

    The researchers also looked at antidepressant use after re-partnering. There was a decline in the use of antidepressants for men and women after starting a new relationship. But this decline was short-lived for women.

    But there’s more to the story

    Although this data alone suggest women may find it harder to adjust to later-life divorce and break-ups than men, it’s important to note some nuances in the interpretation of this data.

    For instance, data suggesting women experience depression more often than men is generally based on the rate of diagnoses and antidepressant use, which does not account for undiagnosed and unmedicated people.

    Women are generally more likely to access medical services and thus receive treatment. This is also the case in Australia, where in 2020–2022, 21.6% of women saw a health professional for their mental health, compared with only 12.9% of men.

    Why women might struggle more after separating

    Nevertheless, relationship dissolution can have a significant impact on people’s mental health. This is particularly the case for women with young children and older women.

    So what factors might explain why women might experience greater difficulties after divorce later in life?

    Research investigating the financial consequences of grey divorce in men and women showed women experienced a 45% decline in their standard of living (measured by an income-to-needs ratio), whereas men’s dropped by just 21%. These declines persisted over time for men, and only reversed for women following re-partnering.

    Another qualitative study investigating the lived experiences of heterosexual couples post-grey divorce identified financial worries as a common theme between female participants.

    A female research participant (age 68) said:

    [I am most worried about] the money, [and] what I’m going to do when the little bit of money I have runs out […] I have just enough money to live. And, that’s it, [and if] anything happens I’m up a creek. And Medicare is incredibly expensive […] My biggest expense is medicine.

    Another factor was loneliness. One male research participant (age 54) described he preferred living with his ex-wife, despite not getting along with her, than being by himself:

    It was still [good] knowing that [the] person was there, and now that’s gone.

    Other major complications of later-life divorce are possible issues with inheritance rights and next-of-kin relationships for medical decision-making.

    Separation can be positive

    For some people, divorce or separation can lead to increased happiness and feeling more independent.

    And the mental health impact and emotional distress of a relationship dissolution is something that can be counterattacked with resilience. Resilience to dramatic events built from life experience means older adults often do respond better to emotional distress and might be able to adjust better to divorce than their younger counterparts.The Conversation

  • AI: The Doctor That Never Tires?

    AI: The Doctor That Never Tires?

    We asked you for your opinion on the use of Artificial Intelligence (AI) in healthcare, and got the above-depicted, below-described set of results:

    • A little over half of respondents to the poll voted for “It speeds up research, and is more methodical about diagnosis, so it’s at least a good extra tool”
    • A quarter of respondents voted for “I’m on the fence—it seems to make no more nor less mistakes than human doctors do”
    • A little under a fifth of respondents voted for “AI is less prone to fatigue/bias than human doctors, making it an essential new tech”
    • Three respondents voted for “AI is a step too far in medical technology, and we’re not ready for it”

    Writer’s note: I’m a professional writer (you’d never have guessed, right?) and, apparently, I really did write “no more nor less mistakes”, despite the correct grammar being “no more nor fewer mistakes”. Now, I know this, and in fact, people getting less/fewer wrong is a pet hate of mine. Nevertheless, I erred.

    Yet, now that I’m writing this out in my usual software, and not directly into the poll-generation software, my (AI!) grammar/style-checker is highlighting the error for me.

    Now, an AI could not do my job. ChatGPT would try, and fail miserably. But can technology help me do mine better? Absolutely!

    And still, I dismiss a lot of the AI’s suggestions, because I know my field and can make informed choices. I don’t follow it blindly, and I think that’s key.

    AI is less prone to fatigue/bias than human doctors, making it an essential new tech: True or False?

    True—with one caveat.

    First, a quick anecdote from a subscriber who selected this option in the poll:

    ❝As long as it receives the same data inputs as my doctor (ie my entire medical history), I can see it providing a much more personalised service than my human doctor who is always forgetting what I have told him. I’m also concerned that my doctor may be depressed – not an ailment that ought to affect AI! I recently asked my newly qualified doctor goddaughter whether she would prefer to be treated by a human or AI doctor. No contest, she said – she’d go with AI. Her argument was that human doctors leap to conclusions, rather than properly weighing all the evidence – meaning AI, as long as it receives the same inputs, will be much more reliable❞

    Now, an anecdote is not data, so what does the science say?

    Well… It says the same:

    ❝Of 6695 responding physicians in active practice, 6586 provided information on the areas of interest: 3574 (54.3%) reported symptoms of burnout, 2163 (32.8%) reported excessive fatigue, and 427 (6.5%) reported recent suicidal ideation, with 255 of 6563 (3.9%) reporting a poor or failing patient safety grade in their primary work area and 691 of 6586 (10.5%) reporting a major medical error in the prior 3 months. Physicians reporting errors were more likely to have symptoms of burnout (77.6% vs 51.5%; P<.001), fatigue (46.6% vs 31.2%; P<.001), and recent suicidal ideation (12.7% vs 5.8%; P<.001).❞

    See the damning report for yourself: Physician Burnout, Well-being, and Work Unit Safety Grades in Relationship to Reported Medical Errors

    AI, of course, does not suffer from burnout, fatigue, or suicidal ideation.

    So, what was the caveat?

    The caveat is about bias. Humans are biased, and that goes for medical practitioners just the same. AI’s machine learning is based on source data, and the source data comes from humans, who are biased.

    See: Bias and Discrimination in AI: A Cross-Disciplinary Perspective

    So, AI can perpetuate human biases and doesn’t have a special extra strength in this regard.

    The lack of burnout, fatigue, and suicidal ideation, however, make a big difference.

    AI speeds up research, and is more methodical about diagnosis: True or False?

    True! AI is getting more and more efficient at this, and as has been pointed out, doesn’t make errors due to fatigue, and often comes to accurate conclusions near-instantaneously. To give just one example:

    ❝Deep learning algorithms achieved better diagnostic performance than a panel of 11 pathologists participating in a simulation exercise designed to mimic routine pathology workflow; algorithm performance was comparable with an expert pathologist interpreting whole-slide images without time constraints. The area under the curve was 0.994 (best algorithm) vs 0.884 (best pathologist).❞

    Read: Diagnostic Assessment of Deep Learning Algorithms for Detection of Lymph Node Metastases in Women With Breast Cancer

    About that “getting more and more efficient at this”; it’s in the nature of machine learning that every new piece of data improves the neural net being used. So long as it is getting fed new data, which it can process at rate far exceeding humans’ abilities, it will always be constantly improving.

    AI makes no more nor less fewer mistakes than humans do: True or False?

    False! AI makes fewer, now. This study is from 2021, and it’s only improved since then:

    ❝Professionals only came to the same conclusions [as each other] approximately 75 per cent of the time. More importantly, machine learning produced fewer decision-making errors than did all the professionals❞

    See: AI can make better clinical decisions than humans: study

    All that said, we’re not quite at Star Trek levels of “AI can do a human’s job entirely” just yet:

    BMJ | Artificial intelligence versus clinicians: pros and cons

    To summarize: medical AI is a powerful tool that:

    • Makes healthcare more accessible
    • Speeds up diagnosis
    • Reduces human error

    …and yet, for now at least, still requires human oversights, checks and balances.

    Essentially: it’s not really about humans vs machines at all. It’s about humans and machines giving each other information, and catching any mistakes made by the other. That way, humans can make more informed decisions, and still keep a “hand on the wheel”.

  • Licorice, Digestion, & Hormones

    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.

    Let’s Take A Look At Licorice…

    Licorice, as a confectionary, is mostly sugar and is useless for medicinal purposes.

    Licorice (Glycyrrhiza sp., most often Glycyrrhiza glabra), in the form of either the root extract (which can be taken as a supplement, or used topically) or the whole root (which can be taken as a powder/capsule, or used to make tea), is a medicinal plant with a long history of use.

    How well-evidenced is it for its popular uses?

    Licorice for digestion

    In this case, it is more accurate to say that it combats indigestion, including acid reflux and ulcerative colitis:

    Systematic Review on Herbal Preparations for Controlling Visceral Hypersensitivity in Functional Gastrointestinal Disorders ← licorice was a top-tier performer in this review

    Network pharmacology mechanisms and experimental verification of licorice in the treatment of ulcerative colitis ← looking at the mechanism of action; ultimately they concluded that “licorice improves ulcerative colitis, which may be related to the activation of the Nrf2/PINK1 signaling pathway that regulates autophagy.“

    Licorice vs menopause symptoms

    This one, while a popular use, isn’t so clear. Here’s a study that examines the compounds in licorice (in this case, Glycyrrhiza uralensis) that interact with estrogen receptors, notes that the bioavailability is poor, and proposes, tests, and recommends a way to make it more bioavailable:

    Development of an Improved Menopausal Symptom-Alleviating Licorice (Glycyrrhiza uralensis) by Biotransformation Using Monascus albidulus

    On the other hand, it is established that it will lower serum testosterone levels, which may make it beneficial for menopause and/or PCOS:

    Polycystic ovaries and herbal remedies: A systematic review

    Licorice for men

    You may be wondering: what about for men? Well, the jury is out on whether it meaningfully reduces free testosterone levels:

    Licorice consumption and serum testosterone in healthy men

    See also:

    Liquorice in moderate doses does not affect sex steroid hormones of biological importance although the effect differs between the genders

    And finally, it may (notwithstanding its disputed effect on testosterone itself) be useful as a safer alternative to finasteride (an antiandrogen mostly commonly used to treat benign prostatic hyperplasia, also used to as a hair loss remedy), since it (like finasteride) modulates 5α-reductase activity (this enzyme converts testosterone to the more potent dihydrogen testosterone, DHT), without lowering sperm count:

    Therapeutic role of Glycyrrhiza Uralensis fisher on benign prostatic hyperplasia through 5 alpha reductase regulation and apoptosis

    Licorice for the skin

    As well as its potentially estrogenic activity, its anti-inflammatory and antioxidant powers make it comparable to hydrocortisone cream for treating eczema, psoriasis, and other such skin conditions:

    New Herbal Biomedicines for the Topical Treatment of Dermatological Disorders

    Is it safe?

    It is “generally recognized as safe”, as the classification goes.

    However, consumed in excess it can cause/worsen hypertension, and other contraindications include if you’re on blood thinners, or have kidney problems.

    As ever, this is a non-exhaustive list, so do speak with your doctor/pharmacist to be sure.

    Life is a marathon, not a sprint. For most of us, at least. But how do we pace ourselves to go the distance, without falling into complacency along the way?

    According to our author Alex Hutchinson, there’s a lot more to it than goal-setting and strategy.

    Hutchinson set out to write a running manual, and ended up writing a manual for life. To be clear, this is still mostly centered around the science of athletic endurance, but covers the psychological factors as much as the physical… and notes how the capacity to endure is the key trait that underlies great performance in every field.

    The writing style is both personal and personable, and parts read like a memoir (Hutchinson himself being a runner and sports journalist), while others are scientific in nature.

    As for the science, the kind of science examined runs the gamut from case studies to clinical studies. We examine not just the science of physical endurance, but the science of psychological endurance too. We learn about such things as:

    • How perception of ease/difficulty plays its part
    • What factors make a difference to pain tolerance
    • How mental exhaustion affects physical performance
    • What environmental factors increase or lessen our endurance
    • …and many other elements that most people don’t consider

    Bottom line: whether you want to run a marathon in under two hours, or just not quit after one minute forty seconds on the exercise bike, or to get through a full day’s activities while managing chronic pain, this book can help.

  • What is reformer pilates? And is it worth the cost?

    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.

    Reformer pilates is steadily growing in popularity, with new studios opening regularly in major cities all over the world.

    But what exactly is reformer pilates? And how does it compare with regular pilates and other types of exercise?

    Classes aren’t cheap so let’s look at the potential benefits and drawbacks to help you decide if it’s right for you.

    Ahmet Kurt/Unsplash

    Pilates with special equipment

    Pilates is a mode of exercise that focuses on core stability and flexibility, while also addressing muscular strength and endurance, balance and general fitness. At first glance, it might look a bit like yoga, with some more traditional weight training components thrown in.

    Reformer pilates uses a piece of equipment called a “reformer”. This looks like a narrow bed that slides along a carriage, has straps to hold onto, and has adjustable springs that add resistance to movement. You perform pilates on the reformer to target specific muscle groups and movement patterns.

    The reformer was first designed to help people recover from injuries. However, it has now become common for general fitness and even sports performance.

    Unlike normal pilates, also known as “mat pilates”, which only uses your body weight, the reformer adds resistance, meaning you can change the difficulty according to your current level of fitness.

    This not only provides a way to overload your muscles, but can make the exercise session more aerobically demanding, which has been proposed to improve cardiovascular fitness.

    What are the benefits of reformer pilates?

    Despite being around for decades, there is surprisingly little research looking at the benefits of reformer pilates. However, what we have seen so far suggests it has a similar effect to other modes of exercise.

    Reformer pilates has been shown to help with weight loss, cause some small increases in muscle mass, and enhance cognitive function. All of these benefits are commonly seen when combining weight training and cardio into the same routine.

    Similarly, among older adults, it has been shown to improve strength, enhance flexibility and may even reduce the risk of falling.

    From a rehabilitation perspective, there is some evidence indicating reformer pilates can improve shoulder health and function, reduce lower back pain and increase flexibility.

    Finally, there is some evidence suggesting a single session of reformer pilates can improve two key markers of cardiovascular health, being flow-mediated dilation and pulse wave velocity, while also improving cholesterol and insulin levels. This suggests reformer pilates could lead to long-term improvements in heart and metabolic health, although more research is needed to confirm this.

    However, there are some key things to consider when discussing these benefits. Most of this research is quite exploratory and comes from a very small number of studies. So we do not know whether these findings will apply to everyone.

    Very few studies compared reformer pilates to other types of exercise. Therefore, while it can improve most aspects of health and function, it’s unlikely reformer pilates provides the optimal mode of exercise for each individual component of physical fitness.

    Traditional weight training, for example, will likely cause larger improvements in strength than reformer pilates. Similarly, stretching will probably make you more flexible. And running or cycling will make you fitter.

    However, if you want a type of exercise that gives you broad overall health benefits, it could be a good option.

    What are the downsides of reformer pilates

    Reformer pilates is not for everyone.

    First and foremost, classes can be expensive compared to other fitness options. You need to be doing at least two to three sessions per week of any type of exercise to maximise the benefits. So even if you can find a class for A$20 or $30, paying for two or three classes a week (or buying a weekly or monthly subscription) is a significant outlay.

    Second, it’s not as accessible as other exercise. Even if you can afford it, not every town or suburb has a reformer pilates studio.

    Third, the effectiveness of your workout is likely to be impacted by how competent your instructor is. There are a host of different pilates qualifications you can get in Australia, and some take much less time than others. With this in mind, it might be best to look for accredited pilates instructors, although this will further reduce the number of options you have available.

    Finally, there is a learning curve. While you will get better over time, the exercise will likely be less effective during those first few weeks (or months) when you are getting used to the machine and the movements.

    Is it right for you?

    Reformer pilates can be a great addition to your fitness routine, especially if you’re looking for a low-impact way to build strength and flexibility.

    But if you have more specific goals, you might need a more specific mode of exercise. For example, if you need to get stronger to improve your ability to manage your daily life, then strength training is probably your best bet. Likewise, if your goal is to run a marathon, you will get more specific benefits from running.

    The cost and availability of reformer pilates make it less accessible for some people. With this in mind, if you are after similar benefits at a lower price point, mat pilates might be a better option. Not only does it have evidence suggesting it can improve strength and fitness, but it is something you can do at home if you find a good resource (YouTube could be a good starting point here).

  • Why 7 Hours Sleep Is Not Enough

    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 Sleep-Deprived Are You, Really?

    This is Dr. Matthew Walker. He’s a neuroscientist and sleep specialist, and is the Director of the Center for Human Sleep Science at UC Berkeley’s Department of Psychology. He’s also the author of the international bestseller “Why We Sleep”.

    What does he want us to know?

    Sleep deprivation is more serious than many people think it is. After about 16 hours without sleep, the brain begins to fail, and needs more than 7 hours of sleep to “reset” cognitive performance.

    Note: note “seven or more”, but “more than seven”.

    After ten days with only 7 hours sleep (per day), Dr. Walker points out, the brain is as dysfunctional as it would be after going without sleep for 24 hours.

    Here’s the study that sparked a lot of Dr. Walker’s work:

    The Cumulative Cost of Additional Wakefulness: Dose-Response Effects on Neurobehavioral Functions and Sleep Physiology From Chronic Sleep Restriction and Total Sleep Deprivation

    Importantly, in Dr. Walker’s own words:

    Three full nights of recovery sleep (i.e., more nights than a weekend) are insufficient to restore performance back to normal levels after a week of short sleeping❞

    ~ Dr. Matthew Walker

    See also: Why You Probably Need More Sleep

    Furthermore: the sleep-deprived mind is unaware of how sleep-deprived it is.

    You know how a drunk person thinks they can drive safely? It’s like that.

    You do not know how sleep-deprived you are, when you are sleep-deprived!

    For example:

    ❝(60.7%) did not signal sleepiness before a sleep fragment occurred in at least one of the four MWT trials❞

    Source: Sleepiness is not always perceived before falling asleep in healthy, sleep-deprived subjects

    Sleep efficiency matters

    With regard to the 7–9 hours band for optimal health, Dr. Walker points out that the sleep we’re getting is not always the sleep we think we’re getting:

    ❝Assuming you have a healthy sleep efficiency (85%), to sleep 9 hours in terms of duration (i.e. to be a long-sleeper), you would need to be consistently in bed for 10 hours and 36 minutes a night. ❞

    ~ Dr. Matthew Walker

    At the bottom end of that, by the way, doing the same math: to get only the insufficient 7 hours sleep discussed earlier, a with a healthy 85% sleep efficiency, you’d need to be in bed for 8 hours and 14 minutes per night.

    The unfortunate implication of this: if you are consistently in bed for 8 hours and 14 minutes (or under) per night, you are not getting enough sleep.

    “But what if my sleep efficiency is higher than 85%?”

    It shouldn’t be.If your sleep efficiency is higher than 85%, you are sleep-deprived and your body is having to enforce things.
