It’s Q&A Day at 10almonds!

Have a question or a request? We love to hear from you!

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

❝Do we really need pores, and why are they bigger on the face?❞

Pores secrete sweat or sebum (there are different kinds of pores for each).

If we didn’t have sweat pores, we’d be unable to sweat, which superficially may seem like a bonus, but it’d make us prone to overheating (like dogs, pigs, and other mammals that cannot sweat).

If we didn’t have sebum pores (usually called hair follicles, which are supplied by a sebaceous gland), we’d be completely hairless, and also unable to supply our skin with natural oils that keep it healthy. So we’d have no hair and very unhappy skin.

Which is ironic, because to believe beauty magazines, we must at all costs minimize our pores (and indeed, interventions like botox* can kill them).

*Let’s give that its full name though:

Botulinum Neurotoxin Type A in the Treatment of Facial Seborrhea and Acne: Evidence and a Proposed Mechanism

Suffice it to say, we do not recommend getting injected with neurotoxins unless it is truly necessary to ward off a greater harm.

As for being bigger on the face, they need not be, but sebaceous glands are more active and numerous there, being most active and numerous in the face/forehead—which is why oily skin is more likely to appear there than other parts of the body.

If your facial sebaceous glands are too active for your liking…

…there are ways to reduce that, a simple and relatively gentle way (relative, for example, botox) is with retinoids, including retinols or retinoic acids. Here’s some of the science of that; the paper is about treating acne, but the mechanism of action is the same (down-regulating the sebaceous glands’ action):

The treatment of severe cystic acne with 13-cis-retinoic acid: evaluation of sebum production and the clinical response in a multiple-dose trial

The potential side-effects, however were noted as:

  • Cheilitis
  • Desquamation of the skin
  • Pruritus

Which, in translation from sciencese, means:

  • Chapped lips
  • Flaky skin
  • Itchiness

Which aren’t necessarily fun, which is why with retinoids are best taken in very small doses at first to see how your skin reacts.

Remember when we said what your skin would be like without pores? This is what would happen, only much worse.

Take care!

  • Are Brain Chips Safe?

    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.

    Ready For Cyborgization?

    A bar chart showing the percentage of people who use social media, emphasizing its safety.

    In yesterday’s newsletter, we asked you for your views on Brain-Computer Interfaces (BCIs), such as the Utah Array and Neuralink’s chips on/in brains that allow direct communication between brains and computers, so that (for example) a paralysed person can use a device to communicate, or manipulate a prosthetic limb or two.

    We didn’t get as many votes as usual; it’s possible that yesterday’s newsletter ended up in a lot of spam filters due to repeated use of a word in “extra ______ olive oil” in its main feature!

    However, of the answers we did get…

    • About 54% said “It’s bad enough that our phones spy on us, without BCI monitoring our thoughts as well!”
    • About 23% said “Sounds great in principle, but I don’t think we’re there yet safetywise”
    • About 19% said “Sign me up for technological telepathy! I am ready for assimilation”
    • One (1) person said “Electrode outside the skull are good; chips on the brain are bad”

    But what does the science say?

    We’re not there yet safetywise: True or False?

    True, in our opinion, when it comes to the latest implants, anyway. While it’s very difficult to prove a negative (it could be that everything goes perfectly in human trials), “extraordinary claims require extraordinary evidence”, and so far this seems to be lacking.

    The stage before human trials is usually animal trials, starting with small creatures and working up to non-human primates if appropriate, before finally humans.

    • Good news: the latest hot-topic BCI device (Neuralink) was tested on animals!
    • Bad news: to say it did not go well would be an understatement

    The Gruesome Story of How Neuralink’s Monkeys Actually Died

    The above is a Wired article, and we tend to go for more objective sources, however we chose this one because it links to very many objective sources, including an open letter from the Physicians’ Committee for Responsible Medicine, which basically confirms everything in the Wired article. There are lots of links to primary (medical and legal) sources, too.

    Electrodes outside the skull are good; chips on/in the brain are bad: True or False?

    True or False depending on how they’re done. The Utah Array (an older BCI implant, now 20 years old, though it’s been updated many times since) has had a good safety record, after being used by a few dozen people with paralysis to control devices:

    How the Utah Array is advancing BCI science

    The Utah Array works on the same general principle as Neuralink, but the mechanics of its implementation are very different:

    • The Utah Array involves a tiny bundle of microelectrodes (held together by a rigid structure that looks a bit like a nanoscale hairbrush) put in place by a brain surgeon, and that’s that.
    • The Neuralink has a dynamic web of electrodes, implanted by a little robot that acts like a tiny sewing machine to implant many polymer threads, each containing its own a bunch of electrodes.

    In theory, the latter is much more advanced. In practice, so far, the former has a much better safety record.

    I am right to be a little worried about giving companies access to my brain: True or False?

    True or False, depending on the nature of your concern.

    For privacy: current BCI devices have quite simple switches operated consciously by the user. So while technically any such device that then runs its data through Bluetooth or WiFi could be hacked, this risk is no greater than using a wireless mouse and/or keyboard, because it has access to about the same amount of information.

    For safety: yes, probably there is cause to be worried. Likely the first waves of commercial users of any given BCI device will be severely disabled people who are more likely to waive their rights in the hope of a life-changing assistance device, and likely some of those will suffer if things go wrong.

    Which on the one hand, is their gamble to make. And on the other hand, makes rushing to human trials, for companies that do that, a little more predatory.

    Take care!

  • Fiber Fueled – by Dr. Will Bulsiewicz

    We generally know that for gut health we should eat fiber, but what of the balances of different sorts of fiber?

    That’s one of the main things that make this book stand out—fostering diversity in our microbiome by fostering diversity in our diet. Specifically, diversity of fiber-containing foods.

    The book is part “science made easy for the lay reader”, and part recipe book. The recipes come with shopping lists and a meal planner, though we would recommend to use those as a guide rather than to try to adhere perfectly to them.

    In particular, this reviewer would encourage much more generous use of healthful seasonings… and less reliance on there being leftovers several days later (tasty food gets gone quickly in this house!)

    As for the science, the feel of this is more like reading a science-based observational documentary with explanations, than of reading a science textbook. Studies are mentioned in passing, but not dissected in any detail, and the focus is more on getting the key learnings across.

    Bottom line: if you’d like to boost not just the amount, but also the diversity, of fiber in your diet, and reap the gut-health rewards, this book is a great guide for that!

  • How To Avoid Age-Related Macular Degeneration

    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.

    Avoiding Age-Related Macular Degeneration

    Eye problems can strike at any age, but as we get older, it becomes a lot more likely. In particular, age-related macular degeneration is, as the name suggests, an age-bound disease.

    Is there no escaping it, then?

    The risk factors for age-related macular degeneration are as follows:

    • Being over the age of 55 (can’t do much about this one)
    • Being over the age of 65 (risk climbs sharply now)
    • Having a genetic predisposition (can’t do much about this one)
    • Having high cholesterol (this one we can tackle)
    • Having cardiovascular disease (this one we can tackle)
    • Smoking (so, just don’t)

    Genes predispose; they don’t predetermine. Or to put it another way: genes load the gun, but lifestyle pulls the trigger.

    Preventative interventions against age-related macular degeneration

    Prevention is better than a cure in general, and this especially goes for things like age-related macular degeneration, because the most common form of it has no known cure.

    So first, look after your heart (because your heart feeds your eyes).

    See also: The Mediterranean Diet

    Next, eat to feed your eyes specifically. There’s a lot of research to show that lutein helps avoid age-related diseases in the eyes and the rest of the brain, too:

    See also: Brain Food? The Eyes Have It

    Do supplements help?

    They can! There was a multiple-part landmark study by the National Eye Institute, a formula was developed that reduced the 5-year risk of intermediate disease progressing to late disease by 25–30%. It also reduced the risk of vision loss by 19%.

    You can read about both parts of the study here:

    Age-Related Eye Disease Studies (AREDS/AREDS2): major findings

    As you can see, an improvement was made between the initial study and the second one, by replacing beta-carotene with lutein and zeaxanthin.

    The AREDS2 formula contains:

    • 500 mg vitamin C
    • 180 mg vitamin E
    • 80 mg zinc
    • 10 mg lutein
    • 2 mg copper

    You can learn more about these supplements, and where to get them, here on the NEI’s corner of the official NIH website:

  • Parents are increasingly saying their child is ‘dysregulated’. What does that actually mean?

    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.

    Welcome aboard the roller coaster of parenthood, where emotions run wild, tantrums reign supreme and love flows deep.

    As children reach toddlerhood and beyond, parents adapt to manage their child’s big emotions and meltdowns. Parenting terminology has adapted too, with more parents describing their child as “dysregulated”.

    But what does this actually mean?

    ShUStudio/Shutterstock

    More than an emotion

    Emotional dysregulation refers to challenges a child faces in recognising and expressing emotions, and managing emotional reactions in social settings.

    This may involve either suppressing emotions or displaying exaggerated and intense emotional responses that get in the way of the child doing what they want or need to do.

    Dysregulation” is more than just feeling an emotion. An emotion is a signal, or cue, that can give us important insights to ourselves and our preferences, desires and goals.

    An emotionally dysregulated brain is overwhelmed and overloaded (often, with distressing emotions like frustration, disappointment and fear) and is ready to fight, flight or freeze.

    Developing emotional regulation

    Emotion regulation is a skill that develops across childhood and is influenced by factors such as the child’s temperament and the emotional environment in which they are raised.

    In the stage of emotional development where emotion regulation is a primary goal (around 3–5 years old), children begin exploring their surroundings and asserting their desires more actively.

    It’s typical for them to experience emotional dysregulation when their initiatives are thwarted or criticised, leading to occasional tantrums or outbursts.

    A typically developing child will see these types of outbursts reduce as their cognitive abilities become more sophisticated, usually around the age they start school.

    Express, don’t suppress

    Expressing emotions in childhood is crucial for social and emotional development. It involves the ability to convey feelings verbally and through facial expressions and body language.

    When children struggle with emotional expression, it can manifest in various ways, such as difficulty in being understood, flat facial expressions even in emotionally charged situations, challenges in forming close relationships, and indecisiveness.

    Several factors, including anxiety, attention-deficit hyperactivity disorder (ADHD), autism, giftedness, rigidity and both mild and significant trauma experiences, can contribute to these issues.

    Common mistakes parents can make is dismissing emotions, or distracting children away from how they feel.

    These strategies don’t work and increase feelings of overwhelm. In the long term, they fail to equip children with the skills to identify, express and communicate their emotions, making them vulnerable to future emotional difficulties.

    We need to help children move compassionately towards their difficulties, rather than away from them. Parents need to do this for themselves too.

    Caregiving and skill modelling

    Parents are responsible for creating an emotional climate that facilitates the development of emotion regulation skills.

    Parents’ own modelling of emotion regulation when they feel distressed. The way they respond to the expression of emotions in their children, contributes to how children understand and regulate their own emotions.

    Children are hardwired to be attuned to their caregivers’ emotions, moods, and coping as this is integral to their survival. In fact, their biggest threat to a child is their caregiver not being OK.

    Unsafe, unpredictable, or chaotic home environments rarely give children exposure to healthy emotion expression and regulation. Children who go through maltreatment have a harder time controlling their emotions, needing more brainpower for tasks that involve managing feelings. This struggle could lead to more problems with emotions later on, like feeling anxious and hypervigilant to potential threats.

    Recognising and addressing these challenges early on is essential for supporting children’s emotional wellbeing and development.

    A dysregulated brain and body

    When kids enter “fight or flight” mode, they often struggle to cope or listen to reason. When children experience acute stress, they may respond instinctively without pausing to consider strategies or logic.

    If your child is in fight mode, you might observe behaviours such as crying , clenching fists or jaw, kicking, punching, biting, swearing, spitting or screaming.

    In flight mode, they may appear restless, have darting eyes, exhibit excessive fidgeting, breathe rapidly, or try to run away.

    A shut-down response may look like fainting or a panic attack.

    When a child feels threatened, their brain’s frontal lobe, responsible for rational thinking and problem-solving, essentially goes offline.

    The amygdala, shown here in red, triggers survival mode. pikovit/Shutterstock

    This happens when the amygdala, the brain’s alarm system, sends out a false alarm, triggering the survival instinct.

    In this state, a child may not be able to access higher functions like reasoning or decision-making.

    While our instinct might be to immediately fix the problem, staying present with our child during these moments is more effective. It’s about providing support and understanding until they feel safe enough to engage their higher brain functions again.

    Reframe your thinking so you see your child as having a problem – not being the problem.

    Tips for parents

    Take turns discussing the highs and lows of the day at meal times. This is a chance for you to be curious, acknowledge and label feelings, and model that you, too, experience a range of emotions that require you to put into practice skills to cope and has shown evidence in numerous physical, social-emotional, academic and behavioural benefits.

    Spending even small amounts (five minutes a day!) of quality one-on-one time with your child is an investment in your child’s emotional wellbeing. Let them pick the activity, do your best to follow their lead, and try to notice and comment on the things they do well, like creative ideas, persevering when things are difficult, and being gentle or kind.

    Take a tip from parents of children with neurodiversity: learn about your unique child. Approaching your child’s emotions, temperament, and behaviours with curiosity can help you to help them develop emotion regulation skills.

    When to get help

    If emotion dysregulation is a persistent issue that is getting in the way of your child feeling happy, calm, or confident – or interfering with learning or important relationships with family members or peers – talk to their GP about engaging with a mental health professional.

    Many families have found parenting programs helpful in creating a climate where emotions can be safely expressed and shared.

    Remember, you can’t pour from an empty cup. Parenting requires you to be your best self and tend to your needs first to see your child flourish.

  • Healthy Homemade Flatbreads

    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 recipes sometimes call for the use of flatbreads, or suggest serving with flatbreads. But we want you to be able to have healthy homemade ones! So here’s a very quick and easy recipe. You’ll probably need to order some of the ingredients in, but it’s worth it, and then if you keep a stock of the ingredients, you can whip these up in minutes anytime you want them.

    You will need

    • 1 cup garbanzo bean flour, plus more for dusting
    • 1 cup quinoa flour
    • 2 tbsp ground/milled flaxseed
    • 1 tbsp baking powder
    • 1 tbsp extra virgin olive oil, plus more for the pan
    • ½ tsp MSG, or 1 tsp low-sodium salt, with MSG being the healthier and preferable option
    • ½ tsp onion powder
    • ½ tsp garlic powder
    • ½ tsp dried cumin
    • ½ tsp dried thyme

    Method

    (we suggest you read everything at least once before doing anything)

    1) Mix the flaxseed with ⅓ cup of water and set aside for at least 5 minutes.

    2) Combine the rest of the ingredients in a big bowl, plus the flax mixtures we just made, and an extra ½ cup of water. Knead this into a dough, adding a touch more water if it becomes necessary, but be sparing with it.

    3) Divide the dough into 6 equal portions, shaping each into a ball. Dust a clean surface with the extra garbanzo bean flour, and roll each dough ball into in a thin 6″ circle.

    4) Heat a skillet and add some olive oil for frying; when hot enough, place a dough disk in the pan and cook for a few minutes on each side until golden brown. Repeat with the other 5.

    5) Serve! If you’re looking for a perfect accompaniment to these, try our Hero Homemade Hummus

    Enjoy!
