The Dopamine Myth

The Dopamine Myth
There’s a popular misconception that, since dopamine is heavily involved in addictions, it’s the cause.
We see this most often in the context of non-chemical addictions, such as:
- gambling
- videogames
- social media
And yes, those things will promote dopamine production, and yes, that will feel good. But dopamine isn’t the problem.
Myth: The Dopamine Detox
There’s a trend we’ve mentioned before (it got a video segment a few Fridays back) about the idea of a “dopamine detox“, and how unscientific the idea is.
For a start…
- You cannot detox from dopamine, because dopamine is not a toxin
- You cannot abstain from dopamine, because your brain regulates your dopamine levels to keep them correct*
- If you could abstain from dopamine (and did), you would die, horribly.
*unless you have a serious mental illness, for example:
- forms of schizophrenia and/or psychosis that involve too much dopamine, or
- forms of depression and/or neurodegenerative diseases such as Parkinson’s (and several kinds of dementia) in which you have too little dopamine
- bipolar disorder in which dopamine levels can swing too far each way

Myth: Dopamine is all about pleasure
Dopamine is a pleasure-giving neurotransmitter, but it serves more purposes than that! It also plays a central role in many neurological processes, including:
- Motivation
- Learning and memory
- Motor functions
- Language faculties
- Linear task processing
Note for example how someone taking dopaminergic drugs (prescription or otherwise; could be anything from modafinil to cocaine) is not blissed out… They’re probably in a good mood, sure, but they’re focused, organized, quick-thinking, and so forth! This is not an ad for cocaine; cocaine is very bad for the health. But you see the features? So, what if we could have a little more dopamine… healthily?
Dopamine—à la carte
Let’s look at the examples we gave earlier of non-chemical addictions that are dopaminergic in nature:
- gambling
- videogames
- social media
They’re not actually that rewarding, are they?
- Gamblers lose more than they win
- Gamers cease to care about a game once they have won
- Social media more often results in “doomscrolling”
This is because what prompts the most dopamine is actually the anticipation of reward… not the thing itself, whose reward-pleasure is very fleeting. Nobody looks back at an hour of doomscrolling and thinks “well, that was fun; I’m glad I did that”.
See the science: Liking, Wanting and the Incentive-Sensitization Theory of Addiction
But what if we anticipated a reward from things that are not deleterious to health and productivity? Things that are neutral, or even good for us?
Examples of this include:
- Sex! (remember though, it’s not a race to the finish-line)
- Good, nourishing food (bonus: some foods boost dopamine production nutritionally)
- Exercise/sport (also prompts release of endorphins, win/win!)
- Gamified learning apps (e.g. Duolingo)
- Gamified health/productivity apps (anything with bells and whistles and things that go “ding” and measure streaks etc)

Almonds vs Cashews – 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 almonds to cashews, we picked the almonds.
Why?
Both are great! But here’s why we picked the almonds:
In terms of macros, almonds have a little more protein and more than 4x the fiber. Given how critical fiber is to good health, and how most people in industrialized countries in general (and N. America in particular) aren’t getting enough, we consider this a major win for almonds.
Things are closer to even for vitamins, but almonds have a slight edge. Almonds are higher in vitamins A, B2, B3, B9, and especially 27x higher in vitamin E, while cashews are higher in vitamins B1, B5, B6, C & K. So, a moderate win for almonds.
In the category of minerals, cashews do a bit better on average. Cashews have moderately more copper, iron, phosphorus, selenium, and zinc, while almonds boast 6x more calcium, and slightly more manganese and potassium. We say this one’s a slight win for cashews.
Adding the categories up, however, makes it clear that almonds win the day.
However, of course, enjoy both! Diversity is healthy. Just, if you’re going to choose between them, we recommend almonds.

Olive Oil vs Coconut Oil – 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 extra virgin olive oil to cold-pressed coconut oil, we picked the olive oil.
Why?
While the cold-pressed coconut oil may offer some health benefits due to its lauric acid content, its 80–90% saturated fat content isn’t great for most people. It’s a great oil when applied topically for healthy skin and hair, though!
The extra virgin olive oil has a much more uncontroversially healthy blend of triglycerides, and (in moderation) is universally recognized as very heart-healthy.
Your local supermarket, most likely, has a good extra virgin olive oil, but if you’d like to get some online, here’s an example product on Amazon for your convenience.

Successful Aging – by Dr. Daniel Levitin
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 all know about age-related cognitive decline. What if there’s a flipside, though?
Neuroscientist Dr. Daniel Levitin explores the changes that the brain undergoes with age, and notes that it’s not all downhill.
From cumulative improvements in the hippocampi to a dialling-down of the (often overfunctioning) amygdalae, there are benefits too.
The book examines the things that shape our brains from childhood into our eighties and beyond. Many milestones may be behind us, but neuroplasticity means there’s always time for rewiring. Yes, it also covers the “how”.
We learn also about the neurogenesis promoted by such simple acts as taking a different route and/or going somewhere new, and what other things improve the brain’s healthspan.
The writing style is very accessible “pop-science”, and is focused on being of practical use to the reader.
Bottom line: if you want to get the most out of your aging wizening brain, this book is a great how-to manual.

Morning Routines That Just FLOW
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.
Morning Routines That Just FLOW
“If the hardest thing you have to do in your day is eat a frog, eat that frog first!”, they say.
And, broadly speaking, it is indeed good to get anything stressful out of the way early, so that we can relax afterwards. But…
- Are we truly best at frog-eating when blurry-eyed and sleepy?
- Is there a spoonful of sugar that could make the medicine go down better?
- What do we need to turn eating the frog into an enjoyable activity?
Flow
“Flow” is a concept brought to public consciousness by psychologist Mihaly Csikszentmihalyi, and it refers to a state in which we feel good about what we’re doing, and just keep doing, at a peak performance level.
Writer’s note: as a writer, for example…
Sometimes I do not want to write, I pace to and fro near my computer, going on side-quests like getting a coffee or gazing out of the window into my garden. But once I get going, suddenly, something magical happens and before I know it, I have to trim my writing down because I’ve written too much. That magical window of effortless productivity was a state of flow.
Good morning!
What is a good morning, to you? Build that into your morning! Set parameters around it so you don’t get carried away timewise and find yourself in the afternoon (unless that would work for you!), but first thing in the morning is the time to light up each part of your brain with appropriate neurotransmitters.
Getting the brain juices flowing
Cortisol
When we wake up, we (unless we have some neurochemical imbalance, such as untreated depression) get a spike of cortisol. Cortisol is much-maligned and feared, and indeed it can be very much deleterious to the health in cases of chronic stress. But a little spike now and again is actually beneficial for us.
Quick Tip: if you want to artificially stimulate (or enhance) a morning cortisol spike, a cold shower is the way to go. Or even just a face-plunge into a bowl of ice-water (put ice in it, give it a couple of minutes to chill the water, then put your face in for a count of 30 seconds, or less if you can’t hold your breath that long).
Serotonin
Serotonin is generally thought of as “the happy chemical”, and it’s stimulated by blue/white light, and also by seeing greenery.
Quick tip: to artificially stimulate (or enhance) a morning serotonin boost, your best friend is sunlight. Even sun through a partly-clouded sky will tend to outperform artificial lighting, including artificial sunlight lighting. Try to get sun between 08:30 and 09:00, if you can. Best of all, do it in your garden or nearby park, as the greenery will be an extra boost!
Dopamine
Generally thought of as “the reward chemical”, but it’s also critical for a lot of kinds of brainwork, including language processing and problem-solving.
Quick Tip: to artificially stimulate* a dopamine surge to get you going, do something that you and/or your body finds rewarding. Examples include:
- Exercise, especially in a vigorous burst
- A good breakfast, a nice coffee, whatever feels right to you
- An app that has motivational bells and whistles, a streak for you to complete, etc
Note: another very enjoyable activity might come to mind that doesn’t even require you getting out of bed. Be aware, however, gentleman-readers specifically, that if you complete that activity, you’ll get a prolactin spike that will wipe out the dopamine you just worked up (because prolactin is antagonistic to dopamine). So that one’s probably better for a lazy morning when you can go back to sleep, than a day when you want to get up and go! Ladies, this is less of a worry for us as the physiology an orgasm driven by estrogen+progesterone rather than testosterone is different; there will not usually be a prolactin spike following the spike of dopamine; our orgasm-related dopamine spike is followed by a wave of oxytocin instead (“the cuddle chemical”), which is much more pleasant than prolactin.
*there’s no “(or enhance)” for this one; you won’t get dopamine from doing nothing, that’s just not how “the reward chemical” works
Flow-building in a stack
When you’ve just woken up and are in a blurry morning haze, that’s not the time to be figuring out “what should I be doing next?”, so instead:
- Work out the things you want to incorporate into your morning routine
- Put them in the order that will be easiest to perform—some things will go a lot better after others!
- Remember to also include things that are simply necessary—morning bathroom ablutions, for example
The goal here is to have a this-and-this-and-this-and-this list of items that you can go through without any deviations, and get in the habit of “after item 1 I automatically do item 2, after which I automatically do item 3, after which…”
Implement this, and your mornings will become practically automated, but in a joyous, life-enhancing way that sets you up in good order for whatever you want/need to do!

Plant-Based Salmon Recipe
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.
From Tofu to Salmon
This video (below) by SweetPotatoSoul isn’t just a recipe tutorial; it’s an inspiring journey into the world of vegan cooking, proving that reducing animal products doesn’t have to mean sacrificing flavor.
The key to her vegan salmon is the tofu. However, there’s a trick to the tofu – you have to press it.
Essentially, this involved putting some paper towel on either side of the tofu, and then placing a heavy object on top; this removes excess water and, more importantly, primes the tofu to absorb the flavor of your marinade!
(You’ll want to press the tofu for around 1 hour)
Find the rest of the recipe in the 12-minute video below!
Other Plant-Based Recipes
With there being so many benefits of cutting meat out of your diet, we’ve spent the time reviewing some of the top books on vegan recipes, including The Green Roasting Tin and The Vegan Instant Pot Cookbook. We hope you enjoy them as much as you’ll enjoy this recipe:

Energize! – by Dr. Michael Breus & Stacey Griffith
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 previously reviewed another book book by Dr. Breus, The Power Of When. So what’s different in this one?
While the chronotypes featured in The Power Of When also feature here (and sufficient explanation is given to make this a fine stand-alone book), this book has a lot to do with metabolism also. By considering a person’s genetically predisposed metabolic rate to be fast, medium, or slow (per being an ectomorph, mesomorph, or endomorph), and then putting that next to one’s sleep chronotype, we get 12 sub-categories that in this book each get an optimized protocol of sleep, exercise (further divided into: what kind of exercise when), and eating/fasting.
Which, in effect, amounts to a personalized coaching program for optimized energy!
The guidance is based on a combination of actual science plus “if this then that” observation-based principles—of the kind that could be described as science if they had been studied clinically instead of informally. Dr. Breus is a sleep scientist, by the way, and his co-author Stacey Griffith is a fitness coach. So between the two of them, they have sleep and exercise covered, and the fasting content is very reasonable and entirely consistent with current consensus of good practice.
The style is very pop-psychology, and very readable, and has a much more upbeat feel than The Power Of When, which seems to be because of Griffith’s presence as a co-author (most of the book is written from a neutral perspective, and some parts have first-person sections by each of the authors, so the style becomes distinct accordingly).
Bottom line: if you’d like to be more energized but [personal reason why not here] then this book may not fix all your problems, but it’ll almost certainly make a big difference and help you to stop sabotaging things and work with your body rather than against it.
