Why Zebras Don’t Get Ulcers – by Dr. Robert M. Sapolsky

The book does kick off with a section that didn’t age well—he talks of the stress induced globally by the Spanish Flu pandemic of 1918, and how that kind of thing just doesn’t happen any more. Today, we have much less existentially dangerous stressors!

However, the fact we went and had another pandemic really only adds weight to the general arguments of the book, rather than detracting.

We are consistently beset by “the slings and arrows of outrageous fortune” as Shakespeare would put it, and there’s a reason (or twenty) why many people go grocery-shopping with the cortisol levels of someone being hunted for sport.

So, why don’t zebras get ulcers, as they actually are hunted for food?

They don’t have rent to pay or a mortgage, they don’t have taxes, or traffic, or a broken washing machine, or a project due in the morning. Their problems come one at a time. They have a useful stress response to a stressful situation (say, being chased by lions), and when the danger is over, they go back to grazing. They have time to recover.

For us, we are (usually) not being chased by lions. But we have everything else, constantly, around the clock. So, how to fix that?

Dr. Sapolsky comprehensively describes our physiological responses to stress in quite different terms than many. By reframing stress responses as part of the homeostatic system—trying to get the body back into balance—we find a solution, or rather: ways to help our bodies recover.

The style is “pop-science” and is very accessible for the lay reader while still clearly coming from a top-level academic who is neck-deep in neuroendocrinological research. Best of both worlds!

Bottom line: if you try to take very day at a time, but sometimes several days gang up on you at once, and you’d like to learn more about what happens inside you as a result and how to fix that, this book is for you!

  • Hate salad or veggies? Just keep eating them. Here’s how our tastebuds adapt to what we eat

    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.

    Do you hate salad? It’s OK if you do, there are plenty of foods in the world, and lots of different ways to prepare them.

    But given almost all of us don’t eat enough vegetables, even though most of us (81%) know eating more vegetables is a simple way to improve our health, you might want to try.

    If this idea makes you miserable, fear not, with time and a little effort you can make friends with salad.

    Why don’t I like salads?

    It’s an unfortunate quirk of evolution that vegetables are so good for us but they aren’t all immediately tasty to all of us. We have evolved to enjoy the sweet or umami (savoury) taste of higher energy foods, because starvation is a more immediate risk than long-term health.

    Vegetables aren’t particularly high energy but they are jam-packed with dietary fibre, vitamins and minerals, and health-promoting compounds called bioactives.

    Those bioactives are part of the reason vegetables taste bitter. Plant bioactives, also called phytonutrients, are made by plants to protect themselves against environmental stress and predators. The very things that make plant foods bitter, are the things that make them good for us.

    Unfortunately, bitter taste evolved to protect us from poisons, and possibly from over-eating one single plant food. So in a way, plant foods can taste like poison.

    For some of us, this bitter sensing is particularly acute, and for others it isn’t so bad. This is partly due to our genes. Humans have at least 25 different receptors that detect bitterness, and we each have our own genetic combinations. So some people really, really taste some bitter compounds while others can barely detect them.

    This means we don’t all have the same starting point when it comes to interacting with salads and veggies. So be patient with yourself. But the steps toward learning to like salads and veggies are the same regardless of your starting point.

    It takes time

    We can train our tastes because our genes and our receptors aren’t the end of the story. Repeat exposures to bitter foods can help us adapt over time. Repeat exposures help our brain learn that bitter vegetables aren’t posions.

    And as we change what we eat, the enzymes and other proteins in our saliva change too. This changes how different compounds in food are broken down and detected by our taste buds. How exactly this works isn’t clear, but it’s similar to other behavioural cognitive training.

    Add masking ingredients

    The good news is we can use lots of great strategies to mask the bitterness of vegetables, and this positively reinforces our taste training.

    Salt and fat can reduce the perception of bitterness, so adding seasoning and dressing can help make salads taste better instantly. You are probably thinking, “but don’t we need to reduce our salt and fat intake?” – yes, but you will get more nutritional bang-for-buck by reducing those in discretionary foods like cakes, biscuits, chips and desserts, not by trying to avoid them with your vegetables.

    Adding heat with chillies or pepper can also help by acting as a decoy to the bitterness. Adding fruits to salads adds sweetness and juiciness, this can help improve the overall flavour and texture balance, increasing enjoyment.

    Pairing foods you are learning to like with foods you already like can also help.

    The options for salads are almost endless, if you don’t like the standard garden salad you were raised on, that’s OK, keep experimenting.

    Experimenting with texture (for example chopping vegetables smaller or chunkier) can also help in finding your salad loves.

    Challenge your biases

    Challenging your biases can also help the salad situation. A phenomenon called the “unhealthy-tasty intuition” makes us assume tasty foods aren’t good for us, and that healthy foods will taste bad. Shaking that assumption off can help you enjoy your vegetables more.

    When researchers labelled vegetables with taste-focused labels, priming subjects for an enjoyable taste, they were more likely to enjoy them compared to when they were told how healthy they were.

    The bottom line

    Vegetables are good for us, but we need to be patient and kind with ourselves when we start trying to eat more.

    Try working with biology and brain, and not against them.

    And hold back from judging yourself or other people if they don’t like the salads you do. We are all on a different point of our taste-training journey.The Conversation

  • Tuna Steak with Protein Salad

    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.

    Yes, it’s protein on protein today, and it’s all healthy.

    You will need (per person)

    • 1 tuna steak
    • 1 400g/12oz can mixed beans, drained & rinsed
    • 1 tsp capers
    • 2 tsp black pepper, coarse ground
    • 1 red chili, chopped
    • 1 lime, cut into wedges
    • ½ tsp white wine vinegar
    • Extra virgin olive oil, for cooking
    • Garnish: chopped parsley

    Method

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

    1) Put the beans in a bowl, mixing in the capers, vinegar, and 1 tsp of the black pepper

    2) Gently rub a little olive oil onto each side of the tuna steak, and season with the remainder of the black pepper (as in, the other tsp, not the rest of what you have in the house).

    3) Heat a ridged grill pan until hot, and then cook the tuna for around 3 minutes on each side. Do not jiggle it! Do not slide it, and definitely do not stir it. Just gently turn it over when necessary. The edges should be cooked, and the inside should still be pink (it’s easy to forget when it comes from a can, but remember tuna is usually eaten raw)

    4) Serve, sprinkling with the chopped chili and garnishing with the parsley. The lime wedges go on the side for squeezing at the table.

    Enjoy!

  • Blood-Sugar Balancing Beetroot Cutlets

    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.

    These beetroot cutlets are meaty and proteinous and fibrous and even have a healthy collection of fats, making these much better for your heart and blood than an animal-based equivalent.

    You will need

    • 1 can kidney beans, drained and rinsed (or 1 cup same, cooked, drained, and rinsed)
    • ½ cup chopped roasted or steamed beetroot, blotted dry
    • ½ cup chopped walnuts (if allergic, substitute with ¼ cup pumpkin seeds)
    • ½ cup cooked (ideally: mixed) grains of your choice (if you need gluten-free, there are plenty of gluten-free grains and pseudocereals)
    • ¼ cup finely chopped onion
    • ¼ bulb garlic, minced or crushed
    • 2 tbsp nutritional yeast
    • 2 tbsp ground flaxseeds
    • 2 tbsp ground chia seeds
    • 2 tsp tomato purée
    • 1 tsp black pepper
    • ½ tsp white miso paste
    • ½ tsp smoked paprika
    • ½ tsp cayenne pepper
    • ¼ tsp MSG or ½ tsp low-sodium salt

    Method

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

    1) Combine the beetroot, beans, walnuts, grains, and onion in a food processor, and process until a coarse even mixture.

    2) Add the remaining ingredients and process to mix thoroughly.

    3) Transfer the mixture to a clean work surface and divide into six balls. If the structural integrity is not good (i.e. too soft), add a little more of any or all of these ingredients: chopped walnuts, ground flax, ground chia, nutritional yeast.

    4) Press the balls firmly into cutlets, and refrigerate for at least 1 hour, but longer is even better if you have the time. Alternatively, if you’d like to freeze them for later use, then this is the point at which to do that.

    5) Preheat the oven to 375℉ / 190℃.

    6) Roast the cutlets on a baking tray lined with baking paper, for about 30 minutes, turning over carefully with a spatula halfway through. They should be firm when done; if they’re not, give them a little longer.

    7) Serve hot, for example on a bed of greens and with a drizzle of aged balsamic vinegar.

    Enjoy!

  • Imposter Syndrome (and why almost everyone has it)

    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.

    Imposter Syndrome (and why almost everyone has it)

    Imposter syndrome is the pervasive idea that we’re not actually good enough, people think we are better than we are, and at any moment we’re going to get found out and disappoint everyone.

    Beyond the workplace

    Imposter syndrome is most associated with professionals. It can range from a medical professional who feels like they’ve been projecting an image of confidence too much, to a writer or musician who is sure that their next piece will never live up to the acclaim of previous pieces and everyone will suddenly realize they don’t know what they’re doing, to a middle-manager who feels like nobody above or below them realizes how little they know how to do.

    But! Less talked-about (but no less prevalent) is imposter syndrome in other areas of life. New parents tend to feel this strongly, as can the “elders” of a family that everyone looks to for advice and strength and support. Perhaps worst is when the person most responsible for the finances of a household feels like everyone just trusts them to keep everything running smoothly, and maybe they shouldn’t because it could all come crashing down at any moment and everyone will see them for the hopeless shambles of a human being that they really are.

    Feelings are not facts

    And yet (while everyone makes mistakes sometimes) the reality is that we’re all doing our best. Given that imposter syndrome affects up to 82% of people, let’s remember to have some perspective. Everyone feels like they’re winging it sometimes. Everyone feels the pressure.

    Well, perhaps not everyone. There’s that other 18%. Some people are sure they’re the best thing ever. Then again, there’s probably some in that 18% that actually feel worse than the 82%—they just couldn’t admit it, even in an anonymized study.

    But one thing’s for sure: it’s very, very common. Especially in high-performing women, by the way, and people of color. In other words, people who typically “have to do twice as much to get recognized as half as good”.

    That said, the flipside of this is that people who are not in any of those categories may feel “everything is in my favor, so I really have no excuse to not achieve the most”, and can sometimes take very extreme actions to try to avoid perceived failure, and it can be their family that pays the price.

    Things to remember

    If you find imposter syndrome nagging at you, remember these things:

    • There are people far less competent than you, doing the same thing
    • Nobody knows how to do everything themselves, especially at first
    • If you don’t know how to do something, you can usually find out
    • There is always someone to ask for help, or at least advice, or at least support

    At the end of the day, we evolved to eat fruit and enjoy the sun. None of us are fully equipped for all the challenges of the modern world, but if we do our reasonable best, and look after each other (and that means that you too, dear reader, deserve looking after as well), we can all do ok.

  • Tempeh vs Tofu – 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 tempeh to tofu, we picked the tempeh.

    Why?

    Per 100g, tempeh has about 1.5x as many calories, about 2x as much protein, about 3x as much fiber, and about 4x the carbohydrates.

    Which latter sounds like a lot, but really, the amounts here are small—tempeh is under 12% carbohydrates, and most of that is treated by the body as fiber (e.g. it’s a resistant starch).

    Both have no sugar, and both have more or less the same (tiny) amount of fat.

    Micronutrients, you ask? As they’re both made from soybeans, the micronutrient profiles are similar, but exact amounts will depend on the method used, so by all means check labels if comparing products in store. By and large, there’s usually not much difference, though.

    You can see sample stats here:

    Tempeh | Tofu

    In summary

    Both are great, and/but tempeh is the more nutrient-dense of the two.

    Therefore, tempeh is the healthier option, unless you are on a very strictly calorie-controlled diet, in which case, tofu will give you more quantity per calorie.

    Enjoy!

  • Guinness Is Good For You*

    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.

    Guinness Is Good For You*

    *This is our myth-buster edition, so maybe best not take that at face value!

    To this day, writing the words “Guinness is” into Google will autocomplete to “Guinness is good for you”. The ad campaign proclaiming such launched about a hundred years ago, and was based on Guinness as it was when it was launched another hundred years before that.

    Needless to say, none of this was based on modern science.

    Is there any grain of truth?

    Perhaps its strongest health claim, in terms of what stands up to modern scrutiny, is that it does contain some B vitamins. Famously (as it was once given to pregnant women in Ireland on the strength of such) it contains folate (also known as Vitamin B9). How much?

    A 15oz glass of Guinness contains 12.8µg of folate, which is 3.2% of the RDA. In other words, you could get all the folate your body needs by drinking just 32 glasses of Guinness per day.

    With that in mind, you might want to get the non-alcoholic version!

    “I heard you could live on just Guinness and oranges, because it contains everything but vitamin C?”

    The real question is: how long could you live? Otherwise, a facetious answer here could be akin to the “fun fact” that you can drink lava… once.

    Guinness is missing many essential amino acids and fatty acids, several vitamins, and many minerals. Exactly what it’s missing may vary slightly from region to region, as while the broad recipe is the same, some processes add or remove some extra micronutrients.

    As to what you’d die of first, for obvious reasons there have been no studies done on this, but our money would be on liver failure.

    It would also wreak absolute havoc with your kidneys, but kidneys are tricky beasts—you can be down to 10% functionality and unaware that anything’s wrong yet. So we think liver failure would get you first.

    (Need that 0.0% alcohol Guinness link again? Here it is)

    Fun fact: Top contender in the category of “whole food” is actually seaweed (make sure you don’t get too much iodine, though)!

    Or, should we say, top natural contender. Because foods that have been designed by humans to contain everything we need and more for optimized health, such as Huel, do exactly what they say on the tin.

    And in case you’re curious…
