❓ Q&A With 10almonds Subscribers!

Q: You talked about spearmint as reducing testosterone levels, what about ginseng for increasing them?

A: Hormones are complicated and often it’s not a simple matter of higher or lower levels! It can also be a matter of…

  • how your body converts one thing into another
  • how your body responds (or not) to something according to how the relevant hormone’s receptors are doing
  • …and whether there’s anything else blocking those receptors.

All this to say: spearmint categorically is an anti-androgen, but the mechanism of action remains uncertain.

Panax ginseng, meanwhile, is one of the most well-established mysteries in herbal medicine.

Paradoxically, it seems to improve both male and female hormonal regulation, despite being more commonly associated with the former.

But it also…

Bottom line: Panax ginseng is popularly taken to improve natural hormone function, a task at which it appears to excel.

Scientists are still working out exactly how it does the many things it appears to do.

Progress has been made, and it clearly is science rather than witchcraft, but there are still far more unanswered questions than resolved ones!

  • Rice vs Buckwheat – 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 rice to buckwheat, we picked the buckwheat.

    Why?

    It’s a simple one today:

    • The vitamin and mineral profiles are very similar, so neither of these are a swaying factor
    • In terms of macros, rice is higher in carbohydrates while buckwheat is higher in fiber
    • Buckwheat also has more protein, but not by much
    • Buckwheat has the lower glycemic index, and a lower insulin index, too

    While buckwheat cannot always be reasonably used as a substitute for rice (often because the texture would not work the same), in many cases it can be.

    And if you love rice, well, so do we, but variety is also the spice of life indeed, not to mention important for good health. You know that whole “eat 30 different plants per week” thing? Grains count in that tally! So substituting buckwheat in place of rice sometimes seems like a very good bet.

    Not sure where to buy it?

  • Lacking Motivation? Science Has The Answer

    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.

    The Science Of Motivation (And How To Use It To Your Advantage)

    When we do something rewarding, our brain gets a little (or big!) spike of dopamine. Dopamine is popularly associated with pleasure—which is fair— but there’s more to it than this.

    Dopamine is also responsible for motivation itself, as a prime mover before we do the thing that we find rewarding. If we eat a banana, and enjoy it, perhaps because our body needed the nutrients from it, our brain gets a hit of dopamine.

    (and not because bananas contain dopamine; that dopamine is useful for the body, but can’t pass the blood-brain barrier to have an effect on the brain)

    So where does the dopamine in our brain come from? That dopamine is made in the brain itself.

    Key Important Fact: the brain produces dopamine when it expects an activity to be rewarding.

    If you take nothing else away from today’s newsletter, let it be this!

    It makes no difference if the activity is then not rewarding. And, it will keep on motivating you to do something it anticipated being rewarding, no matter how many times the activity disappoints, because it’ll remember the very dopamine that it created, as having been the reward.

    To put this into an example:

    • How often have you spent time aimlessly scrolling social media, flitting between the same three apps, or sifting through TV channels when “there’s nothing good on to watch”?
    • And how often did you think afterwards “that was a good and rewarding use of my time; I’m glad I did that”?

    In reality, whatever you felt like you were in search of, you were really in search of dopamine. And you didn’t find it, but your brain did make some, just enough to keep you going.

    Don’t try to “dopamine detox”, though.

    While taking a break from social media / doomscrolling the news / mindless TV-watching can be a great and healthful idea, you can’t actually “detox” from a substance your body makes inside itself.

    Which is fortunate, because if you could, you’d die, horribly and miserably.

    If you could “detox” completely from dopamine, you’d lose all motivation, and also other things that dopamine is responsible for, including motor control, language faculties, and critical task analysis (i.e. planning).

    This doesn’t just mean that you’d not be able to plan a wedding; it also means:

    • you wouldn’t be able to plan how to get a drink of water
    • you wouldn’t have any motivation to get water even if you were literally dying of thirst
    • you wouldn’t have the motor control to be able to physically drink it anyway

    Read: Dopamine and Reward: The Anhedonia Hypothesis 30 years on

    (this article is deep and covers a lot of ground, but is a fascinating read if you have time)

    Note: if you’re wondering why that article mentions schizophrenia so much, it’s because schizophrenia is in large part a disease of having too much dopamine.

    Consequently, antipsychotic drugs (and similar) used in the treatment of schizophrenia are generally dopamine antagonists, and scientists have been working on how to treat schizophrenia without also crippling the patient’s ability to function.

    Do be clever about how you get your dopamine fix

    Since we are hardwired to crave dopamine, and the only way to outright quash that craving is by inducing anhedonic depression, we have to leverage what we can’t change.

    The trick is: question how much your motivation aligns with your goals (or doesn’t).

    So if you feel like checking Facebook for the eleventieth time today, ask yourself: “am I really looking for new exciting events that surely happened in the past 60 seconds since I last checked, or am I just looking for dopamine?”

    You might then realize: “Hmm, I’m actually just looking for dopamine, and I’m not going to find it there”

    Then, pick something else to do that will actually be more rewarding. It helps if you make a sort of dopa-menu in advance, of things to pick from. You can keep this as a list on your phone, or printed and pinned up near your computer.

    Examples might be: Working on that passion project of yours, or engaging in your preferred hobby. Or spending quality time with a loved one. Or doing housework (surprisingly not something we’re commonly motivated-by-default to do, but actually is rewarding when done). Or exercising (same deal). Or learning that language on Duolingo (all those bells and whistles the app has are very much intentional dopamine-triggers to make it addictive, but it’s not a terrible outcome to be addicted to learning!).

    Basically… Let your brain’s tendency to get led astray work in your favor, by putting things in front of it that will lead you in good directions.

    Things for your health and/or education are almost always great things to allow yourself the “ooh, shiny” reaction and pick them up, try something new, etc.

  • I’ve been given opioids after surgery to take at home. What do I need to know?

    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.

    Opioids are commonly prescribed when you’re discharged from hospital after surgery to help manage pain at home.

    These strong painkillers may have unwanted side effects or harms, such as constipation, drowsiness or the risk of dependence.

    However, there are steps you can take to minimise those harms and use opioids more safely as you recover from surgery.

    Flystock/Shutterstock

    Which types of opioids are most common?

    The most commonly prescribed opioids after surgery in Australia are oxycodone (brand names include Endone, OxyNorm) and tapentadol (Palexia).

    In fact, about half of new oxycodone prescriptions in Australia occur after a recent hospital visit.

    Most commonly, people will be given immediate-release opioids for their pain. These are quick-acting and are used to manage short-term pain.

    Because they work quickly, their dose can be easily adjusted to manage current pain levels. Your doctor will provide instructions on how to adjust the dosage based on your pain levels.

    Then there are slow-release opioids, which are specially formulated to slowly release the dose over about half to a full day. These may have “sustained-release”, “controlled-release” or “extended-release” on the box.

    Slow-release formulations are primarily used for chronic or long-term pain. The slow-release form means the medicine does not have to be taken as often. However, it takes longer to have an effect compared with immediate-release, so it is not commonly used after surgery.

    Controlling your pain after surgery is important. This allows you get up and start moving sooner, and recover faster. Moving around sooner after surgery prevents muscle wasting and harms associated with immobility, such as bed sores and blood clots.

    Everyone’s pain levels and needs for pain medicines are different. Pain levels also decrease as your surgical wound heals, so you may need to take less of your medicine as you recover.

    But there are also risks

    As mentioned above, side effects of opioids include constipation and feeling drowsy or nauseous. The drowsiness can also make you more likely to fall over.

    Opioids prescribed to manage pain at home after surgery are usually prescribed for short-term use.

    But up to one in ten Australians still take them up to four months after surgery. One study found people didn’t know how to safely stop taking opioids.

    Such long-term opioid use may lead to dependence and overdose. It can also reduce the medicine’s effectiveness. That’s because your body becomes used to the opioid and needs more of it to have the same effect.

    Dependency and side effects are also more common with slow-release opioids than immediate-release opioids. This is because people are usually on slow-release opioids for longer.

    Then there are concerns about “leftover” opioids. One study found 40% of participants were prescribed more than twice the amount they needed.

    This results in unused opioids at home, which can be dangerous to the person and their family. Storing leftover opioids at home increases the risk of taking too much, sharing with others inappropriately, and using without doctor supervision.

    How to mimimise the risks

    Before using opioids, speak to your doctor or pharmacist about using over-the-counter pain medicines such as paracetamol or anti-inflammatories such as ibuprofen (for example, Nurofen, Brufen) or diclofenac (for example, Voltaren, Fenac).

    These can be quite effective at controlling pain and will lessen your need for opioids. They can often be used instead of opioids, but in some cases a combination of both is needed.

    Other techniques to manage pain include physiotherapy, exercise, heat packs or ice packs. Speak to your doctor or pharmacist to discuss which techniques would benefit you the most.

    However, if you do need opioids, there are some ways to make sure you use them safely and effectively:

    • ask for immediate-release rather than slow-release opioids to lower your risk of side effects
    • do not drink alcohol or take sleeping tablets while on opioids. This can increase any drowsiness, and lead to reduced alertness and slower breathing
    • as you may be at higher risk of falls, remove trip hazards from your home and make sure you can safely get up off the sofa or bed and to the bathroom or kitchen
    • before starting opioids, have a plan in place with your doctor or pharmacist about how and when to stop taking them. Opioids after surgery are ideally taken at the lowest possible dose for the shortest length of time.

    If you’re concerned about side effects

    If you are concerned about side effects while taking opioids, speak to your pharmacist or doctor. Side effects include:

    • constipation – your pharmacist will be able to give you lifestyle advice and recommend laxatives
    • drowsiness – do not drive or operate heavy machinery. If you’re trying to stay awake during the day, but keep falling asleep, your dose may be too high and you should contact your doctor
    • weakness and slowed breathing – this may be a sign of a more serious side effect such as respiratory depression which requires medical attention. Contact your doctor immediately.

    If you’re having trouble stopping opioids

    Talk to your doctor or pharmacist if you’re having trouble stopping opioids. They can give you alternatives to manage the pain and provide advice on gradually lowering your dose.

    You may experience withdrawal effects, such as agitation, anxiety and insomnia, but your doctor and pharmacist can help you manage these.

    How about leftover opioids?

    After you have finished using opioids, take any leftovers to your local pharmacy to dispose of them safely, free of charge.

    Do not share opioids with others and keep them away from others in the house who do not need them, as opioids can cause unintended harms if not used under the supervision of a medical professional. This could include accidental ingestion by children.

    For more information, speak to your pharmacist or doctor. Choosing Wisely Australia also has free online information about managing pain and opioid medicines.

    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

    I am interested in what I can substitute for ham in bean soup?

    Well, that depends on what the ham was like! You can certainly buy ready-made vegan lardons (i.e. small bacon/ham bits, often in tiny cubes or similar) in any reasonably-sized supermarket. Being processed, they’re not amazing for the health, but are still an improvement on pork.

    Alternatively, you can make your own seitan! Again, seitan is really not a health food, but again, it’s still relatively less bad than pork (unless you are allergic to gluten, in which case, definitely skip this one).

    Alternatively alternatively, in a soup that already contains beans (so the protein element is already covered), you could just skip the ham as an added ingredient, and instead bring the extra flavor by means of a little salt, a little yeast extract (if you don’t like yeast extract, don’t worry, it won’t taste like it if you just use a teaspoon in a big pot, or half a teaspoon in a smaller pot), and a little smoked paprika. If you want to go healthier, you can swap out the salt for MSG, which enhances flavor in a similar fashion while containing less sodium.

    Wondering about the health aspects of MSG? Check out our main feature on this, from last month:

    What’s the deal with MSG?

    I thoroughly enjoy your daily delivery. I’d love to see one for teens too!

    That’s great to hear! The average age of our subscribers is generally rather older, but it’s good to know there’s an interest in topics for younger people. We’ll bear that in mind, and see what we can do to cater to that without alienating our older readers!

    That said: it’s never too soon to be learning about stuff that affects us when we’re older—there are lifestyle factors at 20 that affect Alzheimer’s risk at 60, for example (e.g. drinking—excessive drinking at 20* is correlated to higher Alzheimer’s risk at 60).

    *This one may be less of an issue for our US readers, since the US doesn’t have nearly as much of a culture of drinking under 21 as some places. Compare for example with general European practices of drinking moderately from the mid-teens, or the (happily, diminishing—but historically notable) British practice of drinking heavily from the mid-teens.

    How much turmeric should I take each day?

    Dr. Michael Greger’s research (of “Dr. Greger’s Daily Dozen” and “How Not To Die” fame) recommends getting at least ¼ tsp turmeric per day

    Remember to take it with black pepper though, for a 2000% absorption bonus!

    A great way to get it, if you don’t want to take capsules and don’t want to eat spicy food every day, is to throw a teaspoon of turmeric in when making a pot of (we recommend wholegrain!) rice. Turmeric is very water-soluble, so it’ll be transferred into the rice easily during cooking. It’ll make the rice a nice golden yellow color, and/but won’t noticeably change the taste.

    Again remember to throw in some black pepper, and if you really want to boost the nutritional content,some chia seeds are a great addition too (they’ll get cooked with the rice and so it won’t be like eating seeds later, but the nutrients will be there in the rice dish).

    You can do the same with par-boiled potatoes or other root vegetables, but because cooking those has water to be thrown away at the end (unlike rice), you’ll lose some turmeric in the water.

    Request: more people need to be aware of suicidal tendencies and what they can do to ward them off

    That’s certainly a very important topic! We’ll cover that properly in one of our Psychology Sunday editions. In the meantime, we’ll mention a previous special that we did, that was mostly about handling depression (in oneself or a loved one), and obviously there’s a degree of crossover:

  • What’s Lurking In Your Household Air?

    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.

    As individuals, we can’t do much about the outside air. We can try to spend more time in green spaces* and away from traffic, and we can wear face-masks—as was popular in Tokyo and other such large cities long before the pandemic struck.

    *The well-known mental health benefits aside (and contrary to British politician Amber Rudd’s famous assertion in a televised political debate that “clean air doesn’t grow on trees”), clean air comes mostly from trees—their natural process of respiration scrubs not only carbon dioxide, but also pollutants, from the air before releasing oxygen without the pollutants. Neat!

    See also this study: Site new care homes near trees and away from busy roads to protect residents’ lungs

    We are fortunate to be living in a world where most of us in industrialized countries can exercise a great degree of control over our home’s climate. But, what to do with all that power?

    Temperature

    Let’s start with the basics. Outside temperature may vary, but you probably have heating and air conditioning. There’s a simple answer here; the optimal temperature for human comfort and wellbeing is 20℃ / 68℉:

    Scientists Identify a Universal Optimal Temperature For Life on Earth

    Note: this does not mean that that is the ideal global average temperature, because that would mean the polar caps are completely gone, the methane stored there released, many large cities underwater, currently hot places will be too hot for human life (e.g. outside temperatures above human body temperature), there will be mass extinctions of many kinds of animals and plants, including those we humans require for survival, and a great proliferation of many bugs that will kill us. Basically we need diversity for the planet to survive, arctic through to tropical and yes, even deserts (deserts are important carbon sinks!). The ideal global average temperature is about 14℃ (we currently have about 15℃ and rising).

    But, for setting the thermostat in your home, 20℃ / 68℉ is perfect for most people, though down as far as 17℃ / 61℉ is fine too, provided other things such as humidity are in order. In fact, for sleeping, 18℃ / 62℉ is ideal. This is because the cooler temperature is one of the several things that tell our brain it is nighttime now, and thus trigger secretion of melatonin.

    If you’re wondering about temperatures and respiratory viruses, by the way, check out:

    The Cold Truth About Respiratory Infections: The Pathogens That Came In From The Cold

    Humidity

    Most people pay more attention to the temperature in their home than the humidity, and the latter is just as important:

    ❝Conditions that fall outside of the optimal range of 40–60% can have significant impacts on health, including facilitating infectious transmission and exacerbating respiratory diseases.

    When humidity is too low, it can cause dryness and irritation of the respiratory tract and skin, making individuals more susceptible to infections.

    When humidity is too high, it can create a damp environment that encourages the growth of harmful microorganisms like mould, bacteria, and viruses.❞

    ~ Dr. Gabriella Guarnieri et al.

    So, if your average indoor humidity falls outside of that range, consider getting a humidifier or dehumidifier, to correct it. Example items on Amazon, for your convenience:

    Humidity monitor | Humidifier | Dehumidifier

    See also, about a seriously underestimated killer:

    Pneumonia: Prevention Is Better Than Cure

    Now, one last component to deal with, for perfect indoor air:

    Pollution

    We tend to think of pollution as an outdoors thing, and indeed, the pollution in your home will (hopefully!) be lower than that of a busy traffic intersection. However…

    • The air you have inside comes from outside, and that matters if you’re in an urban area
    • Even in suburban and rural areas, general atmospheric pollutants will reach you, and if you’ve ever been subject to wildfire smoke, you’ll know that’s no fun either.
    • Gas appliances in the home cause indoor pollution, even when carbon monoxide is within levels considered acceptable. This polluting effect is much stronger for open gas flames (such as on gas cookers/stoves, or gas fires), than for closed gas heating systems (such as a gas-powered boiler for central heating).
    • Wood stoves/fireplaces are not an improvement, in fact they are worse, and don’t get us started on coal. You should not be breathing these things, and definitely should not be burning them in an enclosed space.
    • That air conditioning, humidifier, dehumidifier? They may be great for temperature and humidity, but please clean/change the filter more often than you think is necessary, or things will grow there and then your device will be adding pathogens to the air as it goes.
    • Plug-in air-freshening devices? They may smell clean, but they are effectively spraying cleaning fluids into your lungs. So please don’t.

    So, what of air purifiers? They can definitely be of benefit. for example:

    Air Purifiers & Sleep

    But watch out! Because if you don’t clean/change the filter regularly, guess what happens! That’s right, it’ll be colonized with bacteria/fungus and then be blowing those at you.

    And no, not all of them will be visible to the naked eye:

  • Drug companies pay doctors over A$11 million a year for travel and education. Here’s which specialties received the most

    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.

    Drug companies are paying Australian doctors millions of dollars a year to fly to overseas conferences and meetings, give talks to other doctors, and to serve on advisory boards, our research shows.

    Our team analysed reports from major drug companies, in the first comprehensive analysis of its kind. We found drug companies paid more than A$33 million to doctors in the three years from late 2019 to late 2022 for these consultancies and expenses.

    We know this underestimates how much drug companies pay doctors as it leaves out the most common gift – food and drink – which drug companies in Australia do not declare.

    Due to COVID restrictions, the timescale we looked at included periods where doctors were likely to be travelling less and attending fewer in-person medical conferences. So we suspect current levels of drug company funding to be even higher, especially for travel.

    Monster Ztudio/Shutterstock

    What we did and what we found

    Since 2019, Medicines Australia, the trade association of the brand-name pharmaceutical industry, has published a centralised database of payments made to individual health professionals. This is the first comprehensive analysis of this database.

    We downloaded the data and matched doctors’ names with listings with the Australian Health Practitioner Regulation Agency (Ahpra). We then looked at how many doctors per medical specialty received industry payments and how much companies paid to each specialty.

    We found more than two-thirds of rheumatologists received industry payments. Rheumatologists often prescribe expensive new biologic drugs that suppress the immune system. These drugs are responsible for a substantial proportion of drug costs on the Pharmaceutical Benefits Scheme (PBS).

    The specialists who received the most funding as a group were cancer doctors (oncology/haematology specialists). They received over $6 million in payments.

    This is unsurprising given recently approved, expensive new cancer drugs. Some of these drugs are wonderful treatment advances; others offer minimal improvement in survival or quality of life.

    A 2023 study found doctors receiving industry payments were more likely to prescribe cancer treatments of low clinical value.

    Our analysis found some doctors with many small payments of a few hundred dollars. There were also instances of large individual payments.

    Why does all this matter?

    Doctors usually believe drug company promotion does not affect them. But research tells a different story. Industry payments can affect both doctors’ own prescribing decisions and those of their colleagues.

    A US study of meals provided to doctors – on average costing less than US$20 – found the more meals a doctor received, the more of the promoted drug they prescribed.

    Someone lifting a slice of pizza
    Pizza anyone? Even providing a cheap meal can influence prescribing. El Nariz/Shutterstock

    Another study found the more meals a doctor received from manufacturers of opioids (a class of strong painkillers), the more opioids they prescribed. Overprescribing played a key role in the opioid crisis in North America.

    Overall, a substantial body of research shows industry funding affects prescribing, including for drugs that are not a first choice because of poor effectiveness, safety or cost-effectiveness.

    Then there are doctors who act as “key opinion leaders” for companies. These include paid consultants who give talks to other doctors. An ex-industry employee who recruited doctors for such roles said:

    Key opinion leaders were salespeople for us, and we would routinely measure the return on our investment, by tracking prescriptions before and after their presentations […] If that speaker didn’t make the impact the company was looking for, then you wouldn’t invite them back.

    We know about payments to US doctors

    The best available evidence on the effects of pharmaceutical industry funding on prescribing comes from the US government-run program called Open Payments.

    Since 2013, all drug and device companies must report all payments over US$10 in value in any single year. Payment reports are linked to the promoted products, which allows researchers to compare doctors’ payments with their prescribing patterns.

    Analysis of this data, which involves hundreds of thousands of doctors, has indisputably shown promotional payments affect prescribing.

    Medical students on hospital grounds

    US research also shows that doctors who had studied at medical schools that banned students receiving payments and gifts from drug companies were less likely to prescribe newer and more expensive drugs with limited evidence of benefit over existing drugs.

    In general, Australian medical faculties have weak or no restrictions on medical students seeing pharmaceutical sales representatives, receiving gifts, or attending industry-sponsored events during their clinical training. They also have no restrictions on academic staff holding consultancies with manufacturers whose products they feature in their teaching.

    So a first step to prevent undue pharmaceutical industry influence on prescribing decisions is to shelter medical students from this influence by having stronger conflict-of-interest policies, such as those mentioned above.

    A second is better guidance for individual doctors from professional organisations and regulators on the types of funding that is and is not acceptable. We believe no doctor actively involved in patient care should accept payments from a drug company for talks, international travel or consultancies.

    Third, if Medicines Australia is serious about transparency, it should require companies to list all payments – including those for food and drink – and to link health professionals’ names to their Ahpra registration numbers. This is similar to the reporting standard pharmaceutical companies follow in the US and would allow a more complete and clearer picture of what’s happening in Australia.

    Patients trust doctors to choose the best available treatments to meet their health needs, based on scientific evidence of safety and effectiveness. They don’t expect marketing to influence that choice.
