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
We had several requests pertaining to veganism, meatless mondays, and substitutions in recipes—so we’re going to cover those on a different day!
As for questions we’re answering today…
Q: Is there any data on immediate and long term effects of running marathons in one’s forties?
An interesting and very specific question! We didn’t find an overabundance of studies specifically for the short- and long-term effects of marathon-running in one’s 40s, but we did find a couple of relevant ones:
The first looked at marathon-runners of various ages, and found that…
- there are virtually no relevant running time differences (p<0.01) per age in marathon finishers from 20 to 55 years
- the majority of middle-aged and elderly athletes have training histories of less than seven years of running
From which they concluded:
❝The present findings strengthen the concept that considers aging as a biological process that can be considerably speeded up or slowed down by multiple lifestyle related factors.❞
See the study: Performance, training and lifestyle parameters of marathon runners aged 20–80 years: results of the PACE-study
The other looked specifically at the impact of running on cartilage, controlled for age (45 and under vs 46 and older) and activity level (marathon-runners vs sedentary people).
The study had the people, of various ages and habitual activity levels, run for 30 minutes, and measured their knee cartilage thickness (using MRI) before and after running.
They found that regardless of age or habitual activity level, running compressed the cartilage tissue to a similar extent. From this, it can be concluded that neither age nor marathon-running result in long-term changes to cartilage response to running.
Or in lay terms: there’s no reason that marathon-running at 40 should ruin your knees (unless you are doing something wrong).
That may or may not have been a concern you have, but it’s what the study looked at, so hey, it’s information.
Here’s the study: Functional cartilage MRI T2 mapping: evaluating the effect of age and training on knee cartilage response to running
Q: Information on [e-word] dysfunction for those who have negative reactions to [the most common medications]?
When it comes to that particular issue, one or more of these three factors are often involved:
- Hormones
- Circulation
- Psychology
The most common drugs (that we can’t name here) work on the circulation side of things—specifically, by increasing the localized blood pressure. The exact mechanism of this drug action is interesting, albeit beyond the scope of a quick answer here today. On the other hand, the way that they work can cause adverse blood-pressure-related side effects for some people; perhaps you’re one of them.
To take matters into your own hands, so to speak, you can address each of those three things we just mentioned:
Hormones
Ask your doctor (or a reputable phlebotomy service) for a hormone test. If your free/serum testosterone levels are low (which becomes increasingly common in men over the age of 45), they may prescribe something—such as testosterone shots—specifically for that.
This way, it treats the underlying cause, rather than offering a workaround like those common pills whose names we can’t mention here.
Circulation
Look after your heart health; eat for your heart health, and exercise regularly!
Cold showers/baths also work wonders for vascular tone—which is precisely what you need in this matter. By rapidly changing temperatures (such as by turning off the hot water for the last couple of minutes of your shower, or by plunging into a cold bath), your blood vessels will get practice at constricting and maintaining that constriction as necessary.
Psychology
[E-word] dysfunction can also have a psychological basis. Unfortunately, this can also then be self-reinforcing, if recalling previous difficulties causes you to get distracted/insecure and lose the moment. One of the best things you can do to get out of this catch-22 situation is to not worry about it in the moment. Depending on what you and your partner(s) like to do in bed, there are plenty of other equally respectable options, so just switch track!
Having a conversation about this in advance will probably be helpful, so that everyone’s on the same page of the script in that eventuality, and it becomes “no big deal”. Without that conversation, misunderstandings and insecurities could arise for your partner(s) as well as yourself (“aren’t I desirable enough?” etc).
So, to recap, we recommend:
- Have your hormones checked
- Look after your circulation
- Make the decision to have fun!

Healing Arthritis – by Dr. Susan Blum
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 by this author, her Immune System Recovery Plan, and today it’s more specific: healing arthritis
Of course, not all arthritis is rooted in immune dysfunction, but a) all of it is made worse by immune dysfunction and b) rheumatoid arthritis, which is an autoimmune disease, affects 1% of the population.
This book tackles all kinds of arthritis, by focusing on addressing the underlying causes and treating those, and (whether it was the cause or not) reducing inflammation without medication, because that will always help.
The “3 steps” mentioned in the subtitle are three stages of a plan to improve the gut microbiome in such a way that it not only stops worsening your arthritis, but starts making it better.
The style here is on the hard end of pop-science, so if you want something more conversational/personable, then this won’t be so much for you, but if you just want the information and explanation, then this does it just fine, and it has frequent references to the science to back it up, with a reassuringly extensive bibliography.
Bottom line: if you have arthritis and want a book that will help you to get either symptom-free or as close to that as is possible from your current condition (bearing in mind that arthritis is generally degenerative), then this is a great book for that.

Vision for Life, Revised Edition – by Dr. Meir Schneider
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 “ten steps” would be better called “ten exercises”, as they’re ten things that one can (and should) continue to do on an ongoing basis, rather than steps to progress through and then forget about.
We can’t claim to have tested the ten exercises for improvement (this reviewer has excellent eyesight and merely hopes to maintain such as she gets older) but the rationale is compelling, and the public testimonials abundant.
Dr. Schneider also talks about improving and correcting errors of refraction—in other words, doing the job of any corrective lenses you may currently be using. While he doesn’t claim miracles, it turns out there is a lot that can be done for common issues such as near-sightedness and far-sightedness, amongst others.
There’s a large section on managing more chronic pathological eye conditions than this reviewer previously knew existed; in some cases it’s a matter of making sure things don’t get worse, but in many others, there’s a recurring of theme of “and here’s an exercise for correcting that”.
The writing style is a little more “narrative prose” than we’d have liked, but the quality of the content more than makes up for any style preference issues.
Bottom line: the human body is a highly adaptive organism, and sometimes it just needs a little help to correct itself. This book can help with that.

Melatonin: A Safe, Natural Sleep Aid?
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.
Melatonin: A safe sleep supplement?
Melatonin is a hormone normally made in our pineal gland. It helps regulate our circadian rhythm, by making us sleepy.
It has other roles too—it has a part to play in regulating immune function, something that also waxes and wanes as a typical day goes by.
Additionally, since melatonin and cortisol are antagonistic to each other, a sudden increase in either will decrease the other. Our brain takes advantage of this, by giving us a cortisol spike in the morning to help us wake up.
As a supplement, it’s generally enjoyed with the intention of inducing healthy, natural, restorative sleep.
Does it really induce healthy, natural, restorative, sleep?
Yes! Well, “natural” is a little subject and relative, if you’re taking it as a supplement, but it’s something your body produces naturally anyway.
Contrast with, for example, benzodiazepines (that whole family of medications with names ending in -azopan or -alozam), or other tranquilizing drugs that do not so much induce healthy sleep, but rather reduce your brain function and hopefully knock you out, and/but often have unwanted side effects, and a tendency to create dependency.
Melatonin, unlike most of those drugs, does not create dependency, and furthermore, we don’t develop tolerance to it. In other words, the same dose will continue working (we won’t need more and more).
In terms of benefits, melatonin not only reduces the time to fall asleep and increases total sleep time, but also (quite a bonus) improves sleep quality, too:
Meta-Analysis: Melatonin for the Treatment of Primary Sleep Disorders
Because it is a natural hormone rather than a drug with many side effects and interactions, it’s also beneficial for those who need good sleep and/but don’t want tranquilizing:
Any other benefits?
Yes! It can also help guard against Seasonal Affective Disorder, also called seasonal depression. Because SAD is not just about “not enough light = not enough serotonin”, but also partly about circadian rhythm and (the body is not so sure what time of day it is when there are long hours of darkness, or even, in the other hemisphere / other time of year, long hours of daylight), melatonin can help, by giving your brain something to “anchor” onto, provided you take it at the same time each day. See:
- Is seasonal affective disorder a disorder of circadian rhythms?
- The circadian basis of winter depression: the case for low-dose melatonin use
As a small bonus, melatonin also promotes HGH production (important for maintaining bone and muscle mass, especially in later life):
Anything we should worry about?
Assuming taking a recommended dose only (0.5mg–10mg per day), toxicity is highly unlikely, especially given that it has a half-life of only 40–60 minutes, so it’ll be eliminated quite quickly.
However! It does indeed induce sleepiness, so for example, don’t take melatonin and then try to drive or operate heavy machinery—or, ideally, do anything other than go to bed.
It can interfere with some medications. We mentioned that melatonin helps regulate immune function, so for example that’s something to bear in mind if you’re on immunosuppressants or otherwise have an autoimmune disorder. It can also interfere with blood pressure medications and blood thinners, and may make epilepsy meds less effective.
As ever, if in doubt, please speak with your doctor and/or pharmacist.
Where to get it?
As ever, we don’t sell it (or anything else), but for your convenience, here is an example product on Amazon.
Enjoy!

Laziness Does Not Exist – by Dr. Devon Price
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.
Some cultures prize productivity as an ideal above most other things, and it’s certainly so in the US. Not only is this not great for mental health in general, but also—as Dr. Price explains—it’s based on a lie.
Generally speaking, when a person appears lazy there is something stopping them/you from doing better, and it’s not some mystical unseen force of laziness, not a set character trait, not a moral failing. Rather, the root cause may be physical, psychological, socioeconomic, or something else entirely.
Those causes can in some cases be overcome (for example, a little CBT can often set aside perfectionist anxiety that results in procrastination), and in some cases they can’t, at least on an individual level (disabilities often stubbornly remain disabling, and societal problems require societal solutions).
This matters for our mental health in areas well beyond the labor marketplace, of course, and these ideas extend to personal projects and even personal relationships. Whatever it is, if it’s leaving you exhausted, then probably something needs to be changed (even if the something is just “expectations”).
The book does offer practical solutions to all manner of such situations, improving what can be improved, making easier what can be made easier, and accepting what just needs to be accepted.
The style of this book is casual yet insightful and deep, easy-reading yet with all the acumen of an accomplished social psychologist.
Bottom line: if life leaves you exhausted, this book can be the antidote and cure

Sunflower Seeds vs Sesame Seeds – 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 sunflower seeds to sesame seeds, we picked the sunflower.
Why?
In moderation, both are very healthy. We say “in moderation” because they’re both about 50% fat and such fats, while vital for life, are generally best enjoyed in small portions. Of that fat, sunflower has the slightly better fat profile; they’re both mostly poly- and monounsaturated fats, but sunflower has 10% saturated fat while sesame has 15%. Aside from fats, sunflower has slightly more protein and sesame has slightly more carbs. While sesame has slightly more fiber, because of the carb profile sunflower still has the lower glycemic index. All in all, a moderate win for sunflower in the macros category.
You may be wondering, with all that discussion of fats, what they’re like for omega-3, and sesame seeds have more omega-3, though sunflower seeds contain it too. Still, a point in sesame’s favor here.
When it comes to vitamins, sunflower has more of vitamins A, B1, B2, B3, B5, B6, B9, C, E, and choline, while sesame is not higher in any vitamins.
In the category of minerals, sunflower has more phosphorus, potassium, and selenium, while sesame has more calcium, copper, iron, and zinc. This is nominally a marginal win for sesame, but it should be noted that sunflower is still very rich in copper, iron, and zinc too (but not calcium).
Adding up the categories makes for a moderate win for sunflower seeds, but as ever, enjoy both; diversity is best!

Guava vs Passion Fruit – 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 guava to passion fruit, we picked the guava.
Why?
There aren’t many fruits that can beat passion fruit for nutritional density! And even in this case, it wasn’t completely so in every category:
In terms of macros, passion fruit has more carbs and fiber, the ratio of which give it the slightly lower glycemic index. Thus, a modest win for passion fruit in this category.
In the category of vitamins, guava has more of vitamins B1, B5, B6, B9, C, E, and K, while passion fruit has more of vitamins A, B2, and B3. A clear win for guava this time.
When it comes to minerals, it’s a little closer, but: guava has more calcium, copper, manganese, potassium, and zinc, while passion fruit has more iron, magnesium, and phosphorus. So, another win for guava.
Adding up the sections makes for guava winning the day, but by all means enjoy either or both; diversity is good!
