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
❝Does nicotine have any benefits at all? I know it’s incredibly addictive but if you exclude the addiction, does it do anything?❞
Good news: yes, nicotine is a stimulant and can be considered a performance enhancer, for example:
❝Compared with the placebo group, the nicotine group exhibited enhanced motor reaction times, grooved pegboard test (GPT) results on cognitive function, and baseball-hitting performance, and small effect sizes were noted (d = 0.47, 0.46 and 0.41, respectively).❞

However, another study found that its use as a cognitive enhancer was only of benefit when there was already a cognitive impairment:
❝Studies of the effects of nicotinic systems and/or nicotinic receptor stimulation in pathological disease states such as Alzheimer’s disease, Parkinson’s disease, attention deficit/hyperactivity disorder and schizophrenia show the potential for therapeutic utility of nicotinic drugs.
In contrast to studies in pathological states, studies of nicotine in normal-non-smokers tend to show deleterious effects.
This contradiction can be resolved by consideration of cognitive and biological baseline dependency differences between study populations in terms of the relationship of optimal cognitive performance to nicotinic receptor activity.
Although normal individuals are unlikely to show cognitive benefits after nicotinic stimulation except under extreme task conditions, individuals with a variety of disease states can benefit from nicotinic drugs❞

Bad news: its addictive qualities wipe out those benefits due to tolerance and thus normalization in short order. So you may get those benefits briefly, but then you’re addicted and also lose the benefits, as well as also ruining your health—making it a lose/lose/lose situation quite quickly.
As an aside, while nicotine is poisonous per se, in the quantities taken by most users, the nicotine itself is not usually what kills. It’s mostly the other stuff that comes with it (smoking is by far and away the worst of all; vaping is relatively less bad, but that’s not a strong statement in this case) that causes problems.

However, this is still not an argument for, say, getting nicotine gum and thinking “no harmful effects” because then you’ll be get a brief performance boost yes before it runs out and being addicted to it and now being in a position whereby if you stop, your performance will be lower than before you started (since you now got used to it, and it became your new normal), before eventually recovering:
In summary
We recommend against using nicotine in the first place, and for those who are addicted, we recommend quitting immediately if not contraindicated (check with your doctor if unsure; there are some situations where it is inadvisable to take away something your body is dependent on, until you correct some other thing first).

How to Do the Work – by Dr. Nicole LaPera
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 have reviewed some self-therapy books before, and they chiefly have focused on CBT and mindfulness, which are great. This one’s different.
Dr. Nicole LaPera has a bolder vision for what we can do for ourselves. Rather than giving us some worksheets for unraveling cognitive distortions or clearing up automatic negative thoughts, she bids us treat the cause, rather than the symptom.
For most of us, this will be the life we have led. Now, we cannot change the parenting style(s) we received (or didn’t), get a redo on childhood, avoid mistakes we made in our adolescence, or face adult life with the benefit of experience we gained right after we needed it most. But we can still work on those things if we just know how.
The subtitle of this book promsies that the reader can/will “recognise your patterns, heal from your past, and create your self”.
That’s accurate, for the content of the book and the advice it gives.
Dr. LaPera’s focus is on being our own best healer, and reparenting our own inner child. Giving each of us the confidence in ourself; the love and care and/but also firm-if-necessary direction that a (good) parent gives a child, and the trust that a secure child will have in the parent looking after them. Doing this for ourselves, Dr. LaPera holds, allows us to heal from traumas we went through when we perhaps didn’t quite have that, and show up for ourselves in a way that we might not have thought about before.
If the book has a weak point, it’s that many of the examples given are from Dr. LaPera’s own life and experience, so how relatable the specific examples will be to any given reader may vary. But, the principles and advices stand the same regardless.
Bottom line: if you’d like to try self-therapy on a deeper level than CBT worksheets, this book is an excellent primer.

Healthy Heart, Healthy Brain – by Dr. Bradley Bale & Dr. Amy Doneen
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 often written that “what’s good for your heart is good for your brain”, because the former feeds the latter and takes away detritus. You cannot have a healthy brain without a healthy heart.
This book goes into that in more detail than we have ever had room to here! This follows from their previous book “Beat The Heart Attack Gene”, but we’re jumping in here because that book doesn’t really contain anything not also included in this one.
The idea is the same though: it is the authors’ opinion that far too many interventions are occurring far too late, and they want to “wake everyone up” (including their colleagues in the field) to encourage earlier (and broader!) testing.
Fun fact: that also reminded this reviewer that she had a pending invitation for blood tests to check these kinds of things—phlebotomy appointment now booked, yay!
True the spirit of such exhortation to early testing, this book does include diagnostic questionnaires, to help the reader know where we might be at. And, interestingly, while the in-book questionnaire format of “so many points for this answer, so many for that one”, etc is quite normal, what they do differently in the diagnostics is that in cases of having to answer “I don’t know”, it assigns the highest-risk point value, i.e. the test will err on the side of assume the worst, in the case of a reader not knowing, for example, what our triglycerides are like. Which, when one thinks about it, is probably a very sensible reasoning.
There’s a lot of advice about specific clinical diagnostic tools and things to ask for, and also things that may raise an alarm that most people might overlook (including doctors, especially if they are only looking for something else at the time).
You may be wondering: do they actually give advice on what to actually do to improve heart and brain health, or just how to be aware of potential problems? And the answer is that the latter is a route to the former, and yes they do offer comprehensive advice—well beyond “eat fiber and get some exercise”, and even down to the pros and cons of various supplements and medications. When it comes to treating a problem that has been identified, or warding off a risk that has been flagged, the advice is a personalized, tailored, approach. Obviously there’s a limit to how much they can do that in the book, but even so, we see a lot of “if this then that” pointers to optimize things along the way.
The style is… a little salesy for this reviewer’s tastes. That is to say, while it has a lot of information of serious value, it’s also quite padded with self-congratulatory anecdotes about the many occasions the authors have pulled a Dr. House and saved the day when everyone else was mystified or thought nothing was wrong, the wonders of their trademarked methodology, and a lot of hype for their own book, as in, the book that’s already in your hands. Without all this padding, the book could have been cut by perhaps a third, if not more. Still, none of that takes away from the valuable insights that are in the book too.
Bottom line: if you’d like to have a healthier heart and brain, and especially if you’d like to avoid diseases of those two rather important organs, then this book is a treasure trove of information.

Serotonin vs Dopamine (Know The Differences)
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.
Of the various neurotransmitters that people confuse with each other, serotonin and dopamine are the two highest on the list (with oxytocin coming third as people often attribute its effects to serotonin). But, for all they are both “happiness molecules”, serotonin and dopamine are quite different, and are even opposites in some ways:
More than just happiness
Let’s break it down:
Similarities:
- Both are neurotransmitters, neuromodulators, and monoamines.
- Both impact cognition, mood, energy, behavior, memory, and learning.
- Both influence social behavior, though in different ways.
Differences (settle in; there are many):
- Chemical structure:
- Dopamine: catecholamine (derived from phenylalanine and tyrosine)
- Serotonin: indoleamine (derived from tryptophan)
- Derivatives:
- Dopamine → noradrenaline and adrenaline (stress and alertness)
- Serotonin → melatonin (sleep and circadian rhythm)
- Effects on mental state:
- Dopamine: drives action, motivation, and impulsivity.
- Serotonin: promotes calmness, behavioral inhibition, and cooperation.
- Role in memory and learning:
- Dopamine: key in attention and working memory
- Serotonin: crucial for hippocampus activation and long-term memory
Symptoms of imbalance:
- Low dopamine:
- Loss of motivation, focus, emotion, and activity
- Linked to Parkinson’s disease and ADHD
- Low serotonin:
- Sadness, irritability, poor sleep, and digestive issues
- Linked to PTSD, anxiety, and OCD
- High dopamine:
- Excessive drive, impulsivity, addictions, psychosis
- High serotonin:
- Nervousness, nausea, and in extreme cases, serotonin syndrome (which can be fatal)
Brain networks:
- Dopamine: four pathways controlling movement, attention, executive function, and hormones.
- Serotonin: widely distributed across the cortex, partially overlapping with dopamine systems.
Speed of production:
- Dopamine: can spike and deplete quickly; fatigues faster with overuse.
- Serotonin: more stable, releasing steadily over longer periods.
Illustrative examples:
- Coffee boosts dopamine but loses its effect with repeated use.
- Sunlight helps maintain serotonin levels over time.
If you remember nothing else, remember this:
- Dopamine: action, motivation, and alertness.
- Serotonin: contentment, happiness, and calmness.

Bananas vs Grapes – 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 bananas to grapes, we picked the bananas.
Why?
In terms of macros, bananas have more fiber and carbs, the ratio of which gives them the (very slightly) lower glycemic index. The difference in GI is marginal enough that it’d be tied on that point alone, but looking at total fiber figures, we say that having nearly 3x the fiber counts for a win here.
In the category of vitamins, bananas have more of vitamins B2, B3, B5, B6, B7, B9, C, and choline, while grapes have more of vitamins A, B1, E, and K. Thus, an 8:4 win for bananas (and with considerable margins of difference, too).
When it comes to minerals, bananas have more copper, magnesium, phosphorus, potassium*, selenium, and zinc, while grapes have more calcium and manganese. Thus, a 6:2 win for bananas this time.
*because of some popular mentions in TV shows, people get hung up on bananas being a good source of potassium. Which they are, but they’re not even in the top 10 of fruits for potassium. Here’s a non-exhaustive list of fruits that have more potassium than bananas, portion for portion:
- Honeydew melon
- Papaya
- Mango
- Prunes
- Figs
- Dates
- Nectarine
- Cantaloupe melon
- Kiwi
- Orange

It’s worth mentioning polyphenols: black/red grapes do have more abundant polyphenols than bananas, and this is very much a point in their favor; however, we don’t think it’s enough to compensate for bananas beating them in every other category, so we still declare bananas the winner.
Of course, the solution to this dilemma is to enjoy both!

Can We Drink To Good Health? ← while there are polyphenols such as resveratrol in red wine that per se would boost heart health, there’s so little per glass that you may need 100–1000 glasses per day to get the dosage that provides benefits in mouse studies.
If you’re not a mouse, you might even need more than that!

Human Connection In An All-Too-Busy World
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.
Many of us, in many ways, have more discretionary time than ever… On paper.
But rather than the 8-hour block of work of yesteryear, nowadays the things that take our time often come in a series of short bursts that punctuate our day.
This means that while in theory, we have n hours of “free” time per day, we actually have 9 minutes here, 23 minutes there, 1 hour 6 minutes somewhere else, and so on.
Social commitments, meanwhile, tend to require not only that we have time in a block, but also, that the time around that block also be sufficiently free, for travelling, preparation, etc.
The result? “We must do this again, and not leave it so long next time!” we say, sincerely, to the friend whom we will next see again in approximately 17 months’ time.
The problem is how our many theoretically-small obligations reduce the rest of our time to “time confetti”, and that happens on the large scale like we saw above, as well as on the small scale of “Ah, I have an hour to relax between these two things” and then suddenly the time is gone, once again reduced to time confetti:
Time Confetti and the Broken Promise of Leisure
So, how to maintain human connection with people beyond those with whom we live?
Some is infinitely better than none
Let’s say you want to call a friend or relative. There may be generational differences in how much one is expected to arrange this by text first, vs just calling, but either way, you don’t have to have an open-ended block of time, and sometimes, it’s better if you don’t.
Establish, at the start of the call, “Before we get into catching up, how are we for time, by the way? For my part, I’ll have to go by such-and-such a time”, and then work with that.
The benefit of doing this is that you’ll both know enough about the time constraints to use the time appropriately; you won’t run out the clock on smalltalk before getting to something big, and you’ll both come away feeling satisfied that you shared and were shared-with in a meaningful fashion.
In contrast, guessing at time constraints can leave big things clipped off, or else result in someone “looking for a way to politely end this conversation that stopped being interesting a while ago but it’ll seem rude if I say I have to go now”, of the kind that results in someone not being so open to a call next time.
Don’t rush to dismiss texts as a medium for meaningful connection
When text messages were first a thing, you’ll remember how we were all working within a very short character limit and a cost-per-message. It was telegrams for the modern age, basically.
Nowadays, that isn’t so; we can write as much or as little as we like, and this has two benefits:
- We can have longer, meaningful conversations around the other stuff in our life. We can reply in seconds, or after making a cup of tea and thinking about it, or after our grocery-chopping trip, or whenever suits us. Suddenly, time confetti isn’t such a barrier to human connection. Writer’s example: my prime social time in this manner is when I’m cooking dinner (which is often about an hour). There’s no way I could have a phonecall while doing that; my bad hearing notwithstanding, I just have my hands full too often with much else going on. But texting? I can do that in the several-minute gaps between assorted culinary tasks, while I’m waiting for the kettle to boil or the onions to brown or whatever.
- Sometimes, the brevity makes it easier. A quick text saying “Hey, just to let you know I’m thinking of you, and hope your day is going well!”, or “Unrelated to anything: I was just thinking about how I’m glad to have you in my life; you’re a good friend, and I appreciate that more than I often remember to say. Anyway, that’s all; it was just on my mind. I hope your day is going well!”
(The cheery closing words in those last two text message examples help signify: “don’t worry, I’m fine and am not looking for anything from you”, which will help the recipient to relax, and counterintuitively, more likely to reply with some kind words of their own, knowing that they’re not signing up for a potentially deep talk when they also have time confetti issues going on)
Seize the moment (and also let it go)
You probably have many small interactions with strangers, most days. In the store, walking the dog, at the doctor’s office, etc. So, two things:
- Make smalltalk. And if you’re not one for traditional smalltalk topics (weather etc), or even if you are, a level-up is:
- Compliment sincerely. Straight out of “How To Win Friends And Influence People”, of course, but it creates a moment of genuine connection; you say a thing, their day is improved, they smile, you complete your business with a smile of your own and go about your day.
(of course, do steer clear of anything that could be interpreted as flirting, if that is not your intent, and really it should never be your intent when it comes to the captive audience of someone who will get fired if they’re not nice to you)
But, with a little practice, these little moments add up to a lot more human connection than if we treat the strangers with whom we interact as though they were merely part of the scenery.

“Skinny Fat” Explained (& How To Fix 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.
“Skinny fat” is a term you may have seen floating around social media. It describes people who have a low body weight but a high body fat percentage, often resulting in flabby appearance despite being within a weight range considered healthy. Many try dieting and exercising, only to find that neither work.
This video explains what’s going wrong, and how to fix it:
Diet & exercise won’t work if it’s not right
This problem occurs because common weight-loss approaches, such as restrictive dieting and excessive cardio, fail to improve body composition:
- Restrictive dieting reduces both fat and lean mass, keeping the body fat percentage unchanged
- Cardio burns some calories but the underlying metabolic issue hasn’t meaningfully changed, so any loss will be temporary (and most of any immediate loss will be water weight, anyway)
The key to overcoming skinny fat is resistance training. Lifting weights or doing bodyweight exercises helps build muscle, which not only lowers body fat percentage (by simple mathematics; add more muscle and the percentages of other things must go down even if the total amount is the same) and improves overall definition, which is something most people consider nice. However, the real value here is that it actually addresses the underlying metabolic issue—because muscle costs calories to maintain, one’s basal metabolic rate will now be faster, even when you’re sleeping.
This then becomes… Not quite a self-sustaining system, because you do have to still eat well and continue to do resistance training, but your body will be doing most of the work for you, and you’ll find it’s a lot easier to maintain a healthy body composition than to get one in the first place, for exactly the metabolic reason we described.
