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 😎
❝What is the best form of sugar for an energy kick during exercise? Both type of sugar eg glicoae fructose dextrose etc and medium, ie drink, gel, solids etc❞
Great question! Let’s be clear first that we’re going to answer this specifically for the context of during exercise.
Because, if you’re not actively exercising strenuously right at the time when you’re taking the various things we’re going to be talking about, the results will not be the same.
For scenarios that are anything less than “I am exercising right now and my muscles (not joints, or anything else) are feeling the burn”, then instead please see this:
Snacks & Hacks: Eating For Energy (In Ways That Actually Work)
Because, to answer your question, we’re going to be going 100% against the first piece of advice in that article, which was “Skip the quasi-injectables”, i.e., anything marketed as very quick release. Those things are useful for diabetics to have handy just in case of needing to urgently correct a hypo, but for most people most of the time, they’re not. See also:
Which Sugars Are Healthier, And Which Are Just The Same?
However…
When strenuously exercising in a way that is taxing our muscles, we do not have to worry about the usual problem of messing up our glucose metabolism by overloading our body with sugars faster than it can use it (thus: it has to hurriedly convert glucose and shove it anywhere it’ll fit to put it away, which is very bad for us), because right now, in the exercise scenario we’re describing, the body is already running its fastest metabolism and is grabbing glucose anywhere it can find it.
Which brings us to our first key: the best type of sugar for this purpose is glucose. Because:
- glucose: the body can use immediately and easily convert whatever’s spare to glycogen (a polysaccharide of glucose) for storage
- fructose: the body cannot use immediately and any conversion of fructose to glycogen has to happen in the liver, so if you take too much fructose (without anything to slow it down, such as the fiber in whole fruit), you’re not only not going to get usable energy (the sugar is just going to be there in your bloodstream, circulating, not getting used, because it doesn’t trigger insulin release and insulin is the gatekeeper that allows sugar to be used), but also, it’s going to tax the liver, which if done to excess, is how we get non-alcoholic fatty liver disease.
- sucrose: is just a disaccharide of glucose and fructose, so it first gets broken down into those, and then its constituent parts get processed as above. Other disaccharides you’ll see mentioned sometimes are maltose and lactose, but again, they’re just an extra step removed from useful metabolism, so to save space, we’ll leave it at that for those today.
- dextrose: is just glucose, but when the labeller is feeling fancy. It’s technically informational because it specifies what isomer of glucose it is, but basically all glucose found in food is d-glucose, i.e. dextrose. Other isomers of glucose can be synthesized (very expensively) in laboratories or potentially found in obscure places (the universe is vast and weird), but in short: unless someone’s going to extreme lengths to get something else, all glucose we encounter is dextrose, and all (absolutely all) dextrose is glucose.
We’d like to show scientific papers contesting these head-to-head for empirical proof, but since the above is basic chemistry and physiology, all we could find is papers taking this for granted and stating in their initial premise that sports drinks, gels, bars usually contain glucose as their main sugar, potentially with some fructose and sucrose. Like this one:
A Comprehensive Study on Sports and Energy Drinks
As for how to take it, again this is the complete opposite of our usual health advice of “don’t drink your calories”, because in this case, for once…
(and again, we must emphasize: only while actively doing strenuous exercise that is making specifically your muscles burn, not your joints or anything else; if your joints are burning you need to rest and definitely don’t spike your blood sugars because that will worsen inflammation)
…just this once, we do want those sugars to be zipping straight into the blood. Which means: liquid is best for this purpose.
And when we say liquid: gel is the same as a drink, so far as the body is concerned, provided the body in question is adequately hydrated (i.e., you are also drinking water).
Here are a pair of studies (by the same team, with the same general methodology), testing things head-to-head, with endurance cyclists on 6-hour stationary cycle rides:
CHO Oxidation from a CHO Gel Compared with a Drink during Exercise
Meanwhile, liquid beat solid, but only significantly so from the 90-minute mark onwards, and even that significant difference was modest (i.e. it’s clinically significant, it’s a statistically reliable result and improbable as random happenstance, but the actual size of the difference was not huge):
Oxidation of Solid versus Liquid CHO Sources during Exercise
We would hypothesize that the reason that liquids only barely outperformed solids for this task is precisely because the solids in question were also designed for the task. When a company makes a fast-release energy bar, they don’t load it with fiber to slow it down. Which differentiates this greatly from, say, getting one’s sugars from whole fruit.
If the study had compared apples to apple juice, we hypothesize the results would have been very different. But alas, if that study has been done, we couldn’t find it.
Today has been all about what’s best during exercise, so let’s quickly finish with a note on what’s best before and after:

Make Your Negativity Work 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.
What’s The Right Balance?
We’ve written before about positivity the pitfalls and perils of toxic positivity:
How To Get Your Brain On A More Positive Track (Without Toxic Positivity)
…as well as the benefits that can be found from selectively opting out of complaining:
A Bone To Pick… Up And Then Put Back Where We Found It
So… What place, if any, does negativity usefully have in our lives?
Carrot and Stick
We tend to think of “carrot and stick” motivation being extrinsic, i.e. there is some authority figure offering is reward and/or punishment, in response to our reactions.
In those cases when it really is extrinsic, the “stick” can still work for most people, by the way! At least in the short term.
Because in the long term, people are more likely to rebel against a “stick” that they consider unjust, and/or enter a state of learned helplessness, per “I’ll never be good enough to satisfy this person” and give up trying to please them.
But what about when you have your own carrot and stick? What about when it comes to, for example, your own management of your own healthy practices?
Here it becomes a little different—and more effective. We’ll get to that, but first, bear with us for a touch more about extrinsic motivation, because here be science:
We will generally be swayed more easily by negative feelings than positive ones.
For example, a study was conducted as part of a blood donation drive, and:
- Group A was told that their donation could save a life
- Group B was told that their donation could prevent a death
The negative wording given to group B boosted donations severalfold:
Read the paper: Life or Death Decisions: Framing the Call for Help
We have, by the way, noticed a similar trend—when it comes to subject lines in our newsletters. We continually change things up to see if trends change (and also to avoid becoming boring), but as a rule, the response we get from subscribers is typically greater when a subject line is phrased negatively, e.g. “how to avoid this bad thing” rather than “how to have this good thing”.
How we can all apply this as individuals?
When we want to make a health change (or keep up a healthy practice we already have)…
- it’s good to note the benefits of that change/practice!
- it’s even better to note the negative consequences of not doing it
For example, if you want to overcome an addiction, you will do better for your self-reminders to be about the bad consequences of using, more than the good consequences of abstinence.
See also: How To Reduce Or Quit Alcohol
This goes even just for things like diet and exercise! Things like diet and exercise can seem much more low-stakes than substance abuse, but at the end of the day, they can add healthy years onto our lives, or take them off.
Because of this, it’s good to take time to remember, when you don’t feel like exercising or do feel like ordering that triple cheeseburger with fries, the bad outcomes that you are planning to avoid with good diet and exercise.
Imagine yourself going in for that quadruple bypass surgery, asking yourself whether the unhealthy lifestyle was worth it. Double down on the emotions; imagine your loved ones grieving your premature death.
Oof, that was hard-hitting
It was, but it’s effective—if you choose to do it. We’re not the boss of you! Either way, we’ll continue to send the same good health advice and tips and research and whatnot every day, with the same (usually!) cheery tone.
One last thing…
While it’s good to note the negative, in order to avoid the things that lead to it, it’s not so good to dwell on the negative.
So if you get caught in negative thought spirals or the like, it’s still good to get yourself out of those.

The Book Of Hormones – by Dr. Shweta Patel
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 subtitle promising “through every stage of life” is a slight overstatement, as the book barely touches on puberty, but we know that the vast majority of our readers have left that one far behind in the past, so probably this is not such an issue.
Where the book gives more attention is in general adult life, through the years of potential fertility, into menopause and beyond. This means lots about the hormonal fluctuations inherent to the menstrual cycle (both the normal, and the still-quite-commonly abnormal, e.g. in cases of PCOS etc), the before-during-after of pregnancy, and many hormonal matters that are not related to sex hormones, such as stress-related hormones and food-related hormones. As such, the book certainly lives up to its title; it is indeed “the book of hormones”.
The style is light and conversational; we get a lot of lessons in chemistry here, but it never feels like it, and there’s certainly no hard science, just clear and easy explanations.
Bottom line: if you’d like to understand hormones quite comprehensively but in a light-hearted manner, this book is a very pleasant and educational read.

Invigorating Sabzi Khordan
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.
Have you ever looked at the nutritional values and phytochemical properties of herbs, and thought “well that’s all well and good, but we only use a tiny amount”? Sabzi khordan is a herb-centric traditional Levantine sharing platter served most commonly as an appetizer, and it is indeed appetizing! Never again will “start your meal with a green salad to ensure a gentle blood sugar curve” seem like a chore:
You will need
- Large bunch of parsley
- Small bunch of tarragon leaves
- Small bunch of basil leaves
- Small bunch of mint
- Small bunch of sorrel leaves
- 7 oz block of feta cheese (if vegan, a plant-based substitution is fine in culinary terms, but won’t have the same gut-healthy benefits, as plant-based cheeses are not fermented)
- 9 oz labneh-stuffed vine leaves in olive oil (if vegan, same deal as the above, except it’s harder to find plant-based substitutes for labneh (strained yogurt cheese), so you might want to use our Plant-Based Healthy Cream Cheese recipe instead and make your own)
- 2 tbsp za’atar (you can make your own by blending dried hyssop, dried sumac berries, sesame seeds, dried thyme, and salt—but if you haven’t had za’atar before, we recommend first buying some like the one that we linked, so that next time you know what you’re aiming for)
- 3 tbsp extra virgin olive oil
- 10 radishes
- 6 scallions
- 9 oz walnuts, soaked in water overnight and drained
- 1 cucumber, cut into batons
- Warm flatbreads (you can use our Healthy Homemade Flatbreads recipe)
Method
(we suggest you read everything at least once before doing anything)
1) Arrange the feta, labneh, za’atar, and olive oil in separate little serving dishes.
2) Arrange everything else around them on a platter.
3) Serve! You may be thinking: did we really need a recipe to tell us “put the things on a plate”? The answer here is that this one today was shared mostly as a matter of inspiration, because when was the last time you thought to serve herbs as the star of the dish? Plus, it’s an excuse to try za’atar, not something so commonly seen outside of the Levant.

Enjoy!

Discipline is Destiny – by Ryan Holiday
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.
We’ve previously reviewed another of Holiday’s books, The Daily Stoic, and here is another excellent work from the same author.
We’re not a philosophy newsletter, but there are some things that make a big difference to physical and mental health, the habits we build, and the path we take in life for better or for worse.
Self-discipline is one of those things. A lot of the time, we know what we need to do, but knowing isn’t the problem. We need to actually do it! This applies to diet, exercise, sleep, and more.
Holiday gives us, in a casual easy-reading style, timeless principles to lock in strong discipline and good habits for life.
The book’s many small chapters, by the way, are excellent for reading a chapter-per-day as a healthy dose of motivation each morning, if you’re so inclined.
Bottom line: if you’ve noticed that one of the biggest barriers between you and your goals is actually doing the necessary things in a disciplined fashion, then this book will help you become more efficient, and actually get there.

How To Engage Your Whole Brain
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 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:

Are Supplements Worth Taking?
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.
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 😎
❝There seems to be a lot of suggestions to take supplements for every thing, from your head to your toes. I know it’s up to the individual but what are the facts or stats to support taking them versus not?❞
Short answer:
- supplementary vitamins and minerals are probably neither needed nor beneficial for most (more on this later) people, with the exception of vitamin D which most people over a certain age need unless they are white and getting a lot of sun.
- other kinds of supplement can be very beneficial or useless, depending on what they are, of course, and also your own personal physiology.
With regard to vitamins and minerals, in most cases they should be covered by a healthy balanced diet, and the bioavailability is usually better from food anyway (bearing in mind, we say vitamin such-and-such, or name an elemental mineral, but there are usually multiple, often many, forms of each—and supplements will usually use whatever is cheapest to produce and most chemically stable).
However! It is also quite common for food to be grown in whatever way is cheapest and produces the greatest visible yield, rather than for micronutrient coverage.
This goes for most if not all plants, and it goes extra for animals (because of the greater costs and inefficiencies involved in rearing animals).
We wrote about this a while back in a mythbusting edition of 10almonds, covering:
- Food is less nutritious now than it used to be: True or False?
- Supplements aren’t absorbed properly and thus are a waste of money: True or False?
- We can get everything we need from our diet: True or False?
You can read the answers and explanations, and see the science that we presented, here:
Do We Need Supplements, And Do They Work?
You may be wondering: what was that about “most (more on this later) people”?
Sometimes someone will have a nutrient deficiency that can’t be easily remedied with diet. Often this occurs when their body:
- has trouble absorbing that nutrient, or
- does something inconvenient with it that makes a lot of it unusable when it gets it.
…which is why calcium, iron, vitamin B12, and vitamin D are quite common supplements to get prescribed by doctors after a certain age.
Still, it’s best to try getting things from one’s diet first all of all, of course.
Things we can’t (reasonably) get from food
This is another category entirely. There are many supplements that are convenient forms of things readily found in a lot of food, such as vitamins and minerals, or phytochemicals like quercetin, fisetin, and lycopene (to name just a few of very many).
Then there are things not readily found in food, or at least, not in food that’s readily available in supermarkets.
For example, if you go to your local supermarket and ask where the mimosa is, they’ll try to sell you a cocktail mix instead of the roots, bark, or leaves of a tropical tree. It is also unlikely they’ll stock lion’s mane mushroom, or reishi.
If perchance you do get the chance to acquire fresh lion’s mane mushroom, by the way, give it a try! It’s delicious shallow-fried in a little olive oil with black pepper and garlic.
In short, this last category, the things most of us can’t reasonably get from food without going far out of our way, are the kind of thing whereby supplements actually can be helpful.
And yet, still, not every supplement has evidence to support the claims made by its sellers, so it’s good to do your research beforehand. We do that on Mondays, with our “Research Review Monday” editions, of which you can find in our searchable research review archive ← we also review some drugs that can’t be classified as supplements, but mostly, it’s supplements.
Take care!
