We all know that exercise is good for mental health as well as physical. So, what’s so revolutionary about this “revolutionary new science of exercise and the brain”?
A lot of it has to do with the specific neuroscience of how exercise has not only a mood-boosting effect (endorphins) and neuroprotective effect (helping to guard against cognitive decline), but also promotes neuroplasticity… e.g., the creation and strengthening of neural pathways, as well as boosting the structure of the brain in some parts such as the cerebellum.
The book also covers not just “exercise has these benefits”, but also the “how this works” of all kinds of brain benefits, including:
- against Alzheimer’s
- mitigating ADHD
- managing menopause
- dealing with addiction
…and more. And once we understand how something works, we’re far more likely to be motivated to actually do the kinds of exercises that give the specific benefits we want/need. Which is very much the important part!
In short: this book will tell you what you need to know to get you doing the exercises you need to enjoy those benefits—very much worth it!

This Chair Rocks: A Manifesto Against Ageism – by Ashton Applewhite
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 easy to think of ageism as being 80% “nobody will hire me because I am three years away from standard retirement age”, but it’s a lot more pervasive than that. And some of it, perhaps the most insidious, is the ageism that we can sometimes internalize without thinking it through.
10almonds readers love to avoid/reverse aging (and this reviewer is no different!), but it’s good once in a while to consider our priorities and motivations, for example:
- There is merit in being able to live without disability or discomfort
- There is harm in feeling a need to pass for younger than we are
And yet, even things such as disabilities are, Applewhite fairly argues, not to be feared. Absolutely avoided if reasonably possible of course, yes, but if they happen they happen and it’s good that we be able to make our peace with that, because most people have at least some kind of disability before the end, and can still strive to make the most of the precious gift that is life. The goal can and should be to play the hand we’re dealt and to live as well as we can—whatever that latter means for us personally.
Many people’s life satisfaction goes up in later years, and Applewhite hypothesizes that while some of that can be put down to circumstances (often no longer overwhelmed with work etc, often more financially stable), a lot is a matter of having come to terms with “losing” youth and no longer having that fear. Thus, a new, freer age of life begins.
The book does cover many other areas too, more than we can list here (but for example: ranging from pro/con brain differences to sex and intimacy), and the idea that long life is a team sport, and that we should not fall into the all-American trap of putting independence on a pedestal. Reports of how aging works with close-knit communities in the supercentenarian Blue Zones can be considered to quash this quite nicely, for instance.
The style is casual and entertaining, and yet peppered with scholarly citations, which stack up to 30 pages of references at the back.
Bottom line: getting older is a privilege that not everyone gets to have, so who are we to squander it? This book shares a vital sense of perspective, and is a call-to-arms for us all to do better, together.

The Dopa-Bean
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.
Mucuna pruriens, also called the “magic velvet bean”, is an established herbal drug used for the management of male infertility, nervous disorders, and also as an aphrodisiac:
The Magic Velvet Bean of Mucuna pruriens
How it works is more interesting than that, though.
It’s about the dopamine
M. pruriens contains levodopa (L-dopa). That’s right, the same as the dopaminergic medication most often prescribed for Parkinson’s disease. Furthermore, it might even be better than synthetic L-dopa, because:
❝M. pruriens seed extract demonstrated acetylcholinesterase inhibitory activity, while synthetic L-dopa enhanced the activity of the enzyme. It can be concluded that the administration of M. pruriens seed might be effective in protecting the brain against neurodegenerative disorders such as Parkinson’s and Alzheimer’s diseases.
M. pruriens seed extract containing L-dopa has shown less acetylcholinesterase activity stimulation compared with L-dopa, suggesting that the extract might have a superior benefit for use in the treatment of Parkinson’s disease.❞
~ Dr. Narisa Kamkaen et al.
Indeed, it has been tested specifically in (human!) Parkinson’s disease patients, which RCT found:
❝The rapid onset of action and longer on time without concomitant increase in dyskinesias on mucuna seed powder formulation suggest that this natural source of l-dopa might possess advantages over conventional l-dopa preparations in the long term management of Parkinson’s disease❞
~ Dr. Regina Katzenschlager et al.

Beyond Parkinson’s disease
M. pruriens has also been tested and found beneficial in cases of disease other than Parkinson’s, thus:
Mucuna pruriens in Parkinson’s and in some other diseases: recent advancement and future prospective
…but the science is less well-established for things not generally considered related to dopamine, such as cancer, diabetes, and cardiometabolic disorders.
Note, however, that the science for it being neuroprotective is rather stronger.
Against depression
Depression can have many causes, and (especially on a neurological level) diverse presentations. As such, sometimes what works for one person’s depression won’t touch another person’s, because the disease and treatment are about completely different neurotransmitter dysregulations. So, if a person’s depression is due to a shortage of serotonin, for example, then perking up the dopamine won’t help much, and vice versa. See also:
Antidepressants: Personalization Is Key!
When it comes to M. pruriens and antidepressant activity, then predictably it will be more likely to help if your depression is due to too little dopamine. Note that this means that even if your depression is dopamine-based, but the problem is with your dopamine receptors and not the actual levels of dopamine, then this may not help so much, depending on what else you have going on in there.
The science for M. pruriens and depression is young, and we only found non-human animal studies so far, for example:
In summary
It’s good against Parkinson’s in particular and is good against neurodegeneration in general.
It may be good against depression, depending on the kind of depression you have.
Is it safe?
That’s a great question! And the answer is: it depends. For most people, in moderation, it should be fine (but, see our usual legal/medical disclaimer). Definitely don’t take it if you have bipolar disorder or any kind of schizoid/psychotic disorder; it is likely to trigger a manic/psychotic episode if you do.
For more on this, we discussed it (pertaining to L-dopa in general, not M. pruriens specifically) at greater length here:

Brain Benefits in 3 Months…through walking?
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.
Keeping it Simple
Today’s video (below) is another Big Think production (can you tell that we love their work?). Wendy Suzuki does a wonderful job of breaking down the brain benefits of exercise into three categories, within three minutes.
The first question to ask yourself is: what is your current level of fitness?
Low Fitness
Exercising, even if it’s just going on a walk, 2-3 times a week improves baseline mood state, as well as enhances prefrontal and hippocampal function. These areas of the brain are crucial for complex behaviors like planning and personality development, as well as memory and learning.
Mid Fitness
The suggested regimen is, without surprise, to slightly increase your regular workouts over three months. Whilst you’re already getting the benefits from the low-fitness routine, there is a likelihood that you’ll increase your baseline dopamine and serotonin levels–which, of course, we love! Read more on dopamine here, here, or here.
High Fitness
If you consider yourself in the high fitness bracket then well done, you’re doing an amazing job! Wendy Suzuki doesn’t make many suggestions for you; all she mentions is that there is the possibility of “too much” exercise actually having negative effects on the brain. However, if you’re not competing at an Olympic level, you should be fine.
Fitness and Exercise in General
Of course, fitness and exercise are both very broad terms. We would suggest that you find an exercise routine that you genuinely enjoy–something that is easy to continue over the long term. Try browsing different areas of exercise to see what resonates with you. For instance, Total Fitness After 40 is a great book on all things fitness in the second half of your life. Alternatively, search through our archive for fitness-related material.
Anyway, without further ado, here is today’s video:

A Statin-Free Life – by Dr. Aseem Malhotra
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.
Here at 10almonds, we’ve written before about the complexities of statins, and their different levels of risk/benefit for men and women, respectively. It’s a fascinating topic, and merits more than an article of the size we write here!
So, in the spirit of giving pointers of where to find a lot more information, this book is a fine choice.
Dr. Malhotra, a consultant cardiologist and professor of evidence-based medicine, talks genes and lifestyle, drugs and blood. He takes us on a tour of the very many risk factors for heart disease, and how cholesterol levels may be at best an indicator, but less likely a cause, of heart disease, especially for women. Further and even better, he discusses various more reliable indicators and potential causes, too.
Rather than be all doom and gloom, he does offer guidance on how to reduce each of one’s personal risk factors and—which is important—keep on top of the various relevant measures of heart health (including some less commonly tested ones, like the coronary calcium score).
The style is light reading andyet with a lot of reference to hard science, so it’s really the best of both worlds in that regard.
Bottom line: if you’re considering statins, or are on statins and are reconsidering that choice, then this book will (notwithstanding its own bias in its conclusion) help you make a more-informed decision.

How To Heal And Regrow Receding Gums

It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
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
❝So, I have a topic that I’d love you guys to discuss: green tea. I used to try + drink it years ago but I always got an allergic reaction to it. So the question I’d like answered is: Will I still get the same allergic reaction if I take the capsules ? Also, because it’s caffeinated, will taking it interfere with iron pills, other vitamins + meds ? I read that the health benefits of the decaffeinated tea/capsules are not as great as the caffeinated. Any info would be greatly appreciated !! Thanks much !!❞
I’ll answer this one in the first person as I’ve had a similar issue:
I found long ago that taking any kind of tea (not herbal infusions, but true teas, e.g. green tea, black tea, red tea, etc) on an empty stomach made me want to throw up. The feeling would subside within about half an hour, but I learned it was far better to circumvent it by just not taking tea on an empty stomach.
However! I take an l-theanine supplement when I wake up, to complement my morning coffee, and have never had a problem with that. Of course, my physiology is not your physiology, and this “shouldn’t” be happening to either of us in the first place, so it’s not something there’s a lot of scientific literature about, and we just have to figure out what works for us.
I’d hypothesize that the reason tea causes a problem but the supplement doesn’t, is because the reaction is not to the l-theanine, but rather to the tannins in the tea.
This last Monday I wrote (inspired in part by your query) about l-theanine supplementation, and how it doesn’t require caffeine to unlock its benefits after all, by the way. So that’s that part in order.
I can’t speak for interactions with your other supplements or medications without knowing what they are, but I’m not aware of any known issue, beyond that l-theanine will tend to give a gentler curve to the expression of some neurotransmitters. So, if for example you’re talking anything that affects that (e.g. antidepressants, antipsychotics, ADHD meds, sleepy/wakefulness meds, etc) then checking with your doctor is best.
❝Can you do something on collagen and keep use posted on pineapple, and yes love and look forward to each issue❞
Glad you’re enjoying! We did write a main feature on collagen a little while back! Here it is:
We Are Such Stuff As Fish Are Made Of
As for pineapple, there’s not a lot to keep you posted about! Pineapple’s protein-digesting, DNA-unzipping action is well-established and considered harmless (if your mouth feels weird when you eat pineapple or drink pineapple juice, this is why, by the way) because no meaningful damage was done.
For example:
- Pineapple’s bromelain action is akin to taking apart a little lego model brick by brick (easy to fix)
- Clastogenic genotoxicity is more like taking a blowtorch to the lego model (less easy to fix)
Fun fact: pineapple is good against inflammation, because of the very same enzyme!
❝I never knew anything about the l- tea. Where can I purchase it?❞
You can get it online quite easily! Here’s an example on Amazon
❝The 3 most important exercises don’t work if you can’t get on the floor. I’m 78, and have knee replacements. What about 3 best chair yoga stretches? Love your articles!❞
Here are six!
We turn the tables and ask you a question!
We’ll then talk about this tomorrow:

Is It Possible To Lose Weight Quickly?
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.
In Victorian England, weight-loss trends like the dangerous tapeworm diet were popular. While modern fad diets can seem less extreme, they often promise similarly fast results. However, these quick fixes can have similarly harmful consequences:
Not so fast
To illustrate the difference between gradual and extreme dieting, the video bids us consider two identical twins, Sam and Felix:
- Sam adopts a gradual approach, slowly reducing calorie intake and exercising regularly. This causes his body to burn glycogen stores before transitioning to fat as an energy source. Regular exercise helps Sam maintain muscle mass, which boosts his metabolism and supports sustained weight loss.
- Felix drastically cuts calories, forcing his body into starvation mode. He quickly depletes glycogen stores, loses muscle mass, and burns fewer calories, making long-term weight loss more difficult. Although Felix might initially lose water weight, this is temporary and unsustainable.
You cannot “just lose it quickly now, and then worry about healthiness once the weight’s gone”, because you will lose health much more quickly than you will lose fat, and that will sabotage, rather than help, your fat loss journey.Healthy weight loss requires gradual, balanced changes in diet and exercise tailored to individual needs. Extreme diets, whether through calorie restriction or things like elimination of carbs or fats, are unsustainable and shock the body. It’s important to prioritize long-term health over societal pressures for quick weight loss and focus on developing a sustainable, healthy lifestyle.
In short, the quickest way to lose weight and keep it off (without dying), is to lose it slowly.
