How To Engage Your Whole Brain

The Stroke Of Insight That Nobody Wants

This is Dr. Jill Bolte Taylor. She’s a neuroanatomist, who, at the age of 37 (when she was a post-doctoral fellow at Harvard Medical School), had what she refers to as her “stroke of insight”.

That is to say, she had a massive stroke, and after a major brain surgery to remove a clot the size of a golf ball, she spent the next 8 years re-learning to do everything.

Whereas previously she’d been busy mapping the brain to determine how cells communicate with each other, now she was busy mapping whether socks or shoes should go on first. Needless to say, she got an insight into neuroplasticity that few people would hope for.

What does she want us to know?

Dr. Taylor (now once again a successful scientist, lecturer, and author) advocates for “whole brain living”, which involves not taking parts of our brain for granted.

About those parts…

Dr. Taylor wants us to pay attention to all the parts regardless of size, ranging from the two hemispheres, all the way down to the billions of brain cells, and yet even further, to the “trillions of molecular geniuses”—because each brain cell is itself reliant on countless molecules of the many neurochemicals that make up our brain.

For a quick refresher on some of the key players in that latter category, see our Neurotransmitter Cheatsheet 😎

When it comes to the hemispheres, there has historically been a popular belief that these re divided into:

  • The right brain: emotional, imaginative, creative, fluid feeling
  • The left brain: intellectual, analytical, calculating, crystal thinking

…which is not true, anatomically speaking, because there are cells on both sides doing their part of both of these broad categories of brain processes.

However, Dr. Taylor found, while one hemisphere of her brain was much more damaged than the other, that nevertheless she could recover some functions more quickly than others, which, once she was able to resume her career, inspired her model of four distinct ways of cogitating that can be switched-between and played with or against each other:

Meet The Four Characters Inside Your Brain

Why this matters

As she was re-learning everything, the way forward was not quick or easy, and she also didn’t know where she was going, because for obvious reasons, she couldn’t remember, much less plan.

Looking backwards after her eventual full recovery, she noted a lot of things that she needed during that recovery, some of which she got and some of which she didn’t.

Most notably for her, she needed the right kind of support that would allow all four of the above “characters” as she puts it, to thrive and grow. And, when we say “grow” here we mean that literally, because of growing new brain cells to replace the lost ones (as well as the simple ongoing process of slowly replacing brain cells).

For more on growing new brain cells, by the way, see:

How To Grow New Brain Cells (At Any Age)

In order to achieve this in all of the required brain areas (i.e., and all of the required brain functions), she also wants us to know… drumroll please

When to STFU

Specifically, the ability to silence parts of our brain that while useful in general, aren’t necessarily being useful right now. Since it’s very difficult to actively achieve a negative when it comes to brain-stuff (don’t think of an elephant), this means scheduling time for other parts of our brain to be louder. And that includes:

  • scheduling time to feel (emotionally)
  • scheduling time to feel (gut feelings)
  • scheduling time to feel (kinesthetically)

…amongst others.

Note: those three are presented in that order, from least basic to most basic. And why? Because, clever beings that we are, we typically start from a position that’s not remotely basic, such as “overthinking”, for example. So, there’s a wind-down through thinking just the right amount, thinking through simpler concepts, feeling, noticing one’s feelings, noticing noticing one’s feelings, all the way down to what, kinesthetically, are we actually physically feeling.

❝It is interesting to note that although our limbic system fucntions throughout our lifetime, it does not mature. As a result, when our emotional “buttons” are pushed, we retain the ability to react to incoming stimulation as though we were a two-year-old, even when we are adults.❞

~ Dr. Jill Taylor

Of course, sometimes the above is not useful, which is why the ability to switch between brain modes is a very important and useful skill to develop.

And how do we do that? By practising. Which is something that it’s necessary to take up consciously, and pursue consistently. When children are at school, there are (hopefully, ideally) curricula set out to ensure they engage and train all parts of their brain. As adults, this does not tend to get the same amount of focus.

“Children’s brains are still developing”—indeed, and so are adult brains:

The Brain As A Work-In-Progress

Dr. Taylor had the uncommon experience of having to, in many ways, neurologically speaking, redo childhood. And having had a second run at it, she developed an appreciation of the process that most of us didn’t necessarily get when doing childhood just the once.

In other words: take the time to feel stuff; take the time to quiet down your chatty mind, take the time engage your senses, and take it seriously! Really notice, as though for the first time, what the texture of your carpet is like. Really notice, as though for the first time, what it feels like to swallow some water. Really notice, as though for the first time, what it feels like to experience joy—or sadness, or comfort, or anger, or peace. Exercise your imagination. Make some art (it doesn’t have to win awards; it just has to light up your brain!). Make music (again, it’s about wiring your brain in your body, not about outdoing Mozart in composition and/or performance). Make changes! Make your brain work in the ways it’s not in the habit of doing.

If you need a little help switching off parts of your brain that are being too active, so that you can better exercise other parts of your brain that might otherwise have been neglected, you might want to try:

  • Our Top 5 Spices: How Much Is Enough For Benefits?

    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.

    A spoonful of pepper makes the… Hang on, no, that’s not right…

    We know that spices are the spice of life, and many have great health-giving qualities. But…

    1. How much is the right amount?
    2. What’s the minimum to get health benefits?
    3. What’s the maximum to avoid toxicity?

    That last one always seems like a scary question, but please bear in mind: everything is toxic at a certain dose. Oxygen, water, you-name-it.

    On the other hand, many things have a toxicity so low that one could not physically consume it sufficiently faster than the body eliminates it, to get a toxic build-up.

    Consider, for example, the €50 banknote that was nearly withdrawn from circulation because one of the dyes used in it was found to be toxic. However, the note remained in circulation after scientists patiently explained that a person would have to eat many thousands of them to get a lethal dose.

    So, let’s address these questions in reverse order:

    What’s the maximum to avoid toxicity?

    In the case of the spices we’ll look at today, the human body generally* has high tolerance for them if eaten at levels that we find comfortable eating.

    *IMPORTANT NOTE: If you have (or may have) a medical condition that may be triggered by spices, go easier on them (or if appropriate, abstain completely) after you learn about that.

    Check with your own physician if unsure, because not only are we not doctors, we’re specifically not your doctors, and cannot offer personalized health advice.

    We’re going to be talking in averages and generalizations here. Caveat consumator.

    For most people, unless you are taking the spice in such quantities that you are folding space and seeing the future, or eating them as the main constituents of your meal rather than an embellishment, you should be fine. Please don’t enter a chilli-eating contest and sue us.

    What is the minimum to get health benefits and how much should we eat?

    The science of physiology generally involves continuous rather than discrete data, so there’s not so much a hard threshold, as a point at which the benefits become significant. The usefulness of most nutrients we consume, be they macro- or micro-, will tend to have a bell curve.

    In other words, a tiny amount won’t do much, the right amount will have a good result, and usefulness will tail off after that point. To that end, we’re going to look at the “sweet spot” of peaking on the graph.

    Also note: the clinical dose is the dose of the compound, not the amount of the food that one will need to eat to get that dose. For example, food x containing compound y will not usually contain that compound at 100% rate and nothing else. We mention this so that you’re not surprised when we say “the recommended dose is 5mg of compound, so take a teaspoon of this spice”, for example.

    Further note: we only have so much room here, so we’re going to list only the top benefits, and not delve into the science of them. You can see the related main features for more details, though!

    The “big 5” health-giving spices, with their relevant active compound:

    • Black pepper (piperine)
    • Hot pepper* (capsaicin)
    • Garlic (allicin)
    • Ginger (gingerol)
    • Turmeric (curcumin**)

    *Cayenne pepper is very high in capsaicin; chilli peppers are also great

    **not the same thing as cumin, which is a completely different plant. Cumin does have some health benefits of its own, but not in the same league as the spices above, and there’s only so much we have room to cover today.

    Black pepper

    • Benefits: antioxidant, anti-cancer, boosts bioavailability of other nutrients, aids digestion
    • Dosage: 5–20mg for benefits
    • Suggestion: ½ teaspoon of black pepper is sufficient for benefits. However, this writer’s kitchen dictum in this case is “if you can’t see the black pepper in/on the food, add more”—but that’s more about taste!
    • Related main feature: Black Pepper’s Anti-Cancer Arsenal (And More)

    Hot Pepper

    Garlic

    • Benefits: heart health, blood sugar balancing, anti-cancer
    • Dosage: 4–8µg for benefits
    • Suggestion: 1–2 cloves daily is generally good. However, cooking reduces allicin content (and so does oxidation after cutting/crushing), so you may want to adjust accordingly if doing those things.
    • Related main feature: The Many Health Benefits Of Garlic

    Ginger

    • Benefits: anti-inflammatory, antioxidant, anti-nausea
    • Dosage: 3–4g for benefits
    • Suggestion: 1 teaspoon grated raw ginger or ½ a teaspoon powdered ginger, can be used in baking or as part of the seasoning for a stir-fry
    • Related main feature: Ginger Does A Lot More Than You Think

    Turmeric

    Closing notes

    The above five spices are very healthful for most people. Personal physiology can and will vary, so if in doubt, a) check with your doctor b) start at lowest doses and establish your tolerance (or lack thereof).

    Enjoy, and stay well!

  • Is chocolate milk a good recovery drink after a workout? A dietitian reviews the evidence

    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.

    Whether you enjoy chocolate milk regularly, as a weekend treat, or as an occasional dose of childhood nostalgia, it probably wouldn’t be the first option you think of for post-workout recovery.

    Unless you’re on TikTok, perhaps. According to many people on the social media platform, chocolate milk is not only delicious, but it offers benefits comparable to sports drinks after a workout.

    So is there any evidence to support this? Let’s take a look.

    eldar nurkovic/Shutterstock

    Rehydrating after a workout is important

    Water accounts for somewhere between 50% and 60% of our body weight. Water has many important functions in the body, including helping to keep our body at the right temperature through sweating.

    We lose water naturally from our bodies when we sweat, as well as through our breathing and when we go to the toilet. So it’s important to stay hydrated to replenish the water we lose.

    When we don’t, we become dehydrated, which can put a strain on our bodies. Signs and symptoms of dehydration can range from thirst and dizziness to low blood pressure and confusion.

    Athletes, because of their higher levels of exertion, lose more water through sweating and from respiration (when their breathing rate gets faster). If they’re training or competing in hot or humid environments they will sweat even more.

    Dehydration impacts athletes’ performance and like for all of us, can affect their health.

    So finding ways to ensure athletes rehydrate quickly during and after they train or compete is important. Fortunately, sports scientists and dietitians have done research looking at the composition of different fluids to understand which ones rehydrate athletes most effectively.

    The beverage hydration index

    The best hydrating drinks are those the body retains the most of once they’ve been consumed. By doing studies where they give people different drinks in standardised conditions, scientists have been able to determine how various options stack up.

    To this end, they’ve developed something called the beverage hydration index, which measures to what degree different fluids hydrate a person compared to still water.

    According to this index beverages with similar fluid retention to still water include sparkling water, sports drinks, cola, diet cola, tea, coffee, and beer below 4% alcohol. That said, alcohol is probably best avoided when recovering from exercise.

    Beverages with superior fluid retention to still water include milk (both full-fat and skim), soy milk, orange juice and oral rehydration solutions.

    This body of research indicates that when it comes to rehydration after exercise, unflavoured milk (full fat, skim or soy) is better than sports drinks.

    But what about chocolate milk?

    A small study looked at the effects of chocolate milk compared to plain milk on rehydration and exercise performance in futsal players (futsal is similar to soccer but played on a court indoors). The researchers found no difference in rehydration between the two. There’s no other published research to my knowledge looking at how chocolate milk compares to regular milk for rehydration during or after exercise.

    But rehydration isn’t the only thing athletes look for in sports drinks. In the same study, drinking chocolate milk after play (referred to as the recovery period) increased the time it took for the futsal players to become exhausted in further exercise (a shuttle run test) four hours later.

    This was also shown in a review of several clinical trials. The analysis found that, compared to different placebos (such as water) or other drinks containing fat, protein and carbohydrates, chocolate milk lengthened the time to exhaustion during exercise.

    What’s in chocolate milk?

    Milk contains protein, carbohydrates and electrolytes, each of which can affect hydration, performance, or both.

    Protein is important for building muscle, which is beneficial for performance. The electrolytes in milk (including sodium and potassium) help to replace electrolytes lost through sweating, so can also be good for performance, and aid hydration.

    Compared to regular milk, chocolate milk contains added sugar. This provides extra carbohydrates, which are likewise beneficial for performance. Carbohydrates provide an immediate source of energy for athletes’ working muscles, where they’re stored as glycogen. This might contribute to the edge chocolate milk appears to have over plain milk in terms of athletic endurance.

    Coffee-flavoured milk has an additional advantage. It contains caffeine, which can improve athletic performance by reducing the perceived effort that goes into exercise.

    One study showed that a frappe-type drink prepared with filtered coffee, skim milk and sugar led to better muscle glycogen levels after exercise compared to plain milk with an equivalent amount of sugar added.

    So what’s the verdict?

    Evidence shows chocolate milk can rehydrate better than water or sports drinks after exercise. But there isn’t evidence to suggest it can rehydrate better than plain milk. Chocolate milk does appear to improve athletic endurance compared to plain milk though.

    Ultimately, the best drink for athletes to consume to rehydrate is the one they’re most likely to drink.

    While many TikTok trends are not based on evidence, it seems chocolate milk could actually be a good option for recovery from exercise. And it will be cheaper than specialised sports nutrition products. You can buy different brands from the supermarket or make your own at home with a drinking chocolate powder.

    This doesn’t mean everyone should look to chocolate milk when they’re feeling thirsty. Chocolate milk does have more calories than plain milk and many other drinks because of the added sugar. For most of us, chocolate milk may be best enjoyed as an occasional treat.

    Strategic Wellness: planning ahead for a better life!

    This is Dr. Michael Roizen. With hundreds of peer-reviewed publications and 14 US patents, his work has been focused on the importance of lifestyle factors in healthy living. He’s the Chief Wellness Officer at the world-famous Cleveland Clinic, and is known for his “RealAge” test and related personalized healthcare services.

    If you’re curious about that, you can take the RealAge test here.

    (they will require you inputting your email address if you do, though)

    What’s his thing?

    Dr. Roizen is all about optimizing health through lifestyle factors—most notably, diet and exercise. Of those, he is particularly keen on optimizing nutritional habits.

    Is this just the Mediterranean Diet again?

    Nope! Although: he does also advocate for that. But there’s more, he makes the case for what he calls “circadian eating”, optimally timing what we eat and when.

    Is that just Intermittent Fasting again?

    Nope! Although: he does also advocate for that. But there’s more:

    Dr. Roizen takes a more scientific approach. Which isn’t to say that intermittent fasting is unscientific—on the contrary, there’s mountains of evidence for it being a healthful practice for most people. But while people tend to organize their intermittent fasting purely according to convenience, he notes some additional factors to take into account, including:

    • We are evolved to eat when the sun is up
    • We are evolved to be active before eating (think: hunting and gathering)
    • Our insulin resistance increases as the day goes on

    Now, if you’ve a quick mind about you, you’ll have noticed that this means:

    • We should keep our eating to a particular time window (classic intermittent fasting), and/but that time window should be while the sun is up
    • We should not roll out of bed and immediately breakfast; we need to be active for a bit first (moderate exercise is fine—this writer does her daily grocery-shopping trip on foot before breakfast, for instance… getting out there and hunting and gathering those groceries!)
    • We should not, however, eat too much later in the day (so, dinner should be the smallest meal of the day)

    The latter item is the one that’s perhaps biggest change for most people. His tips for making this as easy as possible include:

    • Over-cater for dinner, but eat only one portion of it, and save the rest for an early-afternoon lunch
    • First, however, enjoy a nutrient-dense protein-centric breakfast with at least some fibrous vegetation, for example:
      • Salmon and asparagus
      • Scrambled tofu and kale
      • Yogurt and blueberries

    Enjoy!

  • Calculate (And Enjoy) The Perfect Night’s Sleep

    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 Dr. Michael Breus, a clinical psychologist and sleep specialist, and he wants you to get a good night’s sleep, every night.

    First, let’s assume you know a lot of good advice about how to do that already in terms of environment and preparation, etc. If you want a recap before proceeding, then we recommend:

    Get Better Sleep: Beyond The Basics

    Now, what does he want to add?

    Wake up refreshed

    Of course, how obtainable this is will depend on the previous night’s sleep, but there is something important we can do here regardless, and it’s: beat sleep inertia.

    Sleep inertia is what happens when we wake up groggy (for reasons other than being ill, drugged, etc) rather than refreshed. It’s not actually related to how much sleep we have, though!

    Rather, it pertains to whether we woke up during a sleep cycle, or between cycles:

    • If we wake up between sleep cycles, we’ll avoid sleep inertia.
    • If we wake up during a sleep cycle, we’ll be groggy.

    Deep sleep generally occurs in 90-minute blocks, albeit secretly that is generally 3× 20 minute blocks in a trenchcoat, with transition periods between, during which the brainwaves change frequency.

    REM sleep generally occurs in 20 minute blocks, and will usually arrive in series towards the end of our natural sleep period, to fit neatly into the last 90-minute cycle.

    Sometimes these will appear a little out of order, because we are complicated organic beings, but those are the general trends.

    In any case, the take-away here is: interrupt them at your peril. You need to wake up between cycles. There are two ways you can do this:

    1. Carefully calculate everything, and set a very precise alarm clock (this will work so long as you are correct in guessing how long it will take you to fall asleep)
    2. Use a “sunrise” lamp alarm clock, that in the hour approaching your set alarm time, will gradually increase the light. Because the body will not naturally wake up during a cycle unless a threat is perceived (loud noise, physical rousing, etc), the sunrise lamp method means that you will wake up between sleep cycles at some point during that hour (towards the beginning or end, depending on what your sleep balance/debt is like).

    Do not sleep in (even if you have a sleep debt); it will throw everything out.

    Caffeine will not help much in the morning

    Assuming you got a reasonable night’s sleep, your brain has been cleansed of adenosine (a sleepy chemical), and if you are suffering from sleep inertia, the grogginess is due to melatonin (a different sleepy chemical).

    Caffeine is an adenosine receptor blocker, so that will do nothing to mitigate the effects of melatonin in your brain that doesn’t have any meaningful quantity of adenosine in it in the morning.

    Adenosine gradually accumulates in the brain over the course of the day (and then gets washed out while we sleep), so if you’re sleepy in the afternoon (for reasons other than: you just had a nap and now have sleep inertia again), then caffeine can block that adenosine in the afternoon.

    Of course, caffeine is also a stimulant (it increases adrenaline levels and promotes vasoconstriction), but its effects at healthily small doses are modest for most people, and you’d do better by splashing cold water on your face and/or listening to some upbeat music.

    Learn more: The Two Sides Of Caffeine

    Time your naps correctly (if you take naps)

    Dr. Breus has a lot to say about this, based on a lot of clinical research, but as it’s entirely consistent with what we’ve written before (based on the exact same research), to save space we’ll link to that here:

    How To Be An Expert Nap-Artist (With No “Sleep-Hangovers”)

    Calculate your bedtime correctly

    Remember what we said about sleep cycles? This means that that famous “7–9 hours sleep” is actually “either 7½ or 9 hours sleep”—because those are multiples of 90 minutes, whereas 8 hours (for example) is not.

    So, consider the time you want to get up (ideally, this should be relatively early, and the same time every day), and then count backwards either 7½ or 9 hours sleep (you choose), add 20–30 minutes to fall asleep, and that’s your bedtime.

    So for example: if you want to have 7½ hours sleep and get up at 6am, then your bedtime is anywhere between 10pm and 10:10pm.

    Remember how we said not to sleep in, even if you have a sleep debt? Now is the time to pay it off, if you have one. If you normally sleep 7½ hours, then make tonight a 9-hour sleep (plus 20–30 minutes to fall asleep). This means you’ll still get up at 6am, but your bedtime is now anywhere between 8:30pm and 8:40pm.

  • Peas vs Broad Beans – 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 peas to broad beans, we picked the peas.

    Why?

    Both are great of course, but…

    Looking at the macros to start with, peas have more protein and more fiber. The differences aren’t huge, but they are clear.

    In terms of vitamins, peas have more of vitamins A, B1, B2, B3, B5, B6, B9, E, K, and choline (some with very large margins, some with small), while broad beans contain a little more vitamin C (the margin is quite narrow though).

    When it comes to minerals, peas have more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while broad beans have more sodium. So this category wasn’t close.

    Adding up the win from each of the categories makes for a clear triple-win for peas.

    Easy-peasy!

  • Dr. Kim Foster’s Method For Balancing Hormones Naturally

    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.

    Not just sex hormones, but also hormones like cortisol (the stress hormone), and thyroid hormones (for metabolism regulation) too! The body is most of the time self-regulating when it comes to hormones, but there are things that we can do to help our body look after us correctly.

    In short, if we give our body what it needs, it will (usually, barring serious illness!) give us what we need.

    Dr. Foster recommends…

    Foods:

    • Healthy fats (especially avocados and nuts)
    • Lean proteins (especially poultry, fish, and legumes)
    • Fruits & vegetables (especially colorful ones)
    • Probiotics (especially fermented foods like sauerkraut, kimchi, etc)
    • Magnesium-rich foods (especially dark leafy greens, nuts, and yes, dark chocolate)

    Teas:

    • Camomile tea (especially beneficial against cortisol overproduction)
    • Nettle tea (especially beneficial for estrogen production)
    • Peppermint tea (especially beneficial for gut health, thus indirect hormone benefits)

    Stress reduction:

    • Breathing exercises (especially mindfulness exercises)
    • Yoga (especially combining exercise with stretches)
    • Spending time in nature (especially green spaces)
