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!

Meals That Heal – by Dr. Carolyn Williams
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.
Inflammation is implicated as a contributory or casual factor in almost all chronic diseases (and still exacerbates the ones in which it’s not directly implicated causally), so if there’s one area of health to focus on with one’s diet, then reducing inflammation is a top candidate.
This book sets about doing exactly that.
You may be wondering whether, per the book’s subtitle, they can really all be done in 30 minutes or under. The answer is: no, not unless you have a team of sous-chefs to do all the prep work for you, and line up everything mise-en-place style for when you start the clock. If you do have that team of sous-chefs working for you, then you can probably do most of them in under 30 minutes. If you don’t have that team, then budget about an hour in total, sometimes less, sometimes more, depending on the recipe.
The recipes themselves are mostly Mediterranean-inspired, though you might want to do a few swaps where the author has oddly recommended using seed oils instead of olive oil, or plant milk in place of where she has used dairy milk in a couple of “recipes” for smoothies. You might also want to be a little more generous with the seasonings, if you’re anything like this reviewer.
Bottom line: if you’re looking for an anti-inflammatory starter cookbook, you could do worse than this. You could probably do better, too, such as starting with The Inflammation Spectrum – by Dr. Will Cole.

Pomegranate vs Figs – 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 pomegranate to figs, we picked the pomegranate.
Why?
In terms of macros, pomegranate has a lot more protein* and fiber, while the fig has more carbs. Thus, a win for pomegranate.
*Why such protein in a fruit? In both cases, it’s mostly from the seeds, which in both cases, we’re eating. However, pomegranates have a much greater seed-to-mass ratio than figs, and thus, a correspondingly higher amount of protein. Also some fats from the seeds, again more than figs, but the margin of difference is smaller, and not really enough to be of relevance.
In the category of vitamins, pomegranates lead with more of vitamins B1, B5, B9, C, E, K, and choline, while figs have more of vitamins A, B3, and B6. The largest margins of difference are in vitamins B9, E, and K, so all in pomegranate’s favor.
The minerals scene is closer to even; pomegranate has more copper, phosphorus, potassium, selenium, and zinc, while figs have more calcium, iron, magnesium, and manganese. Thus, a 5:4 lead for pomegranate, and the larger margins of difference are again for pomegranate.
In short, enjoy both, but pomegranates are the more nutritionally dense. Also, don’t throw away the peel! Dry it, and turn it into a powdered supplement—see our linked article below, for why:

Artichoke vs Brussels Sprouts – 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 artichoke to Brussels sprouts, we picked the sprouts.
Why?
Finally, a vegetable that beats artichoke—after it previously beat heart-of-palm, asparagus, and even cabbage! It was still close though, which is impressive for artichoke, considering what a nutritional powerhouse Brussels sprouts are:
In terms of macros, the only meaningful difference is that artichoke has slightly more carbs and fiber, so artichoke gets the most marginal of nominal wins in this category.
In the category of vitamins, however, artichoke has more of vitamins B3, B9, and choline, while Brussels sprouts have more of vitamins A, B1, B2, B6, C, E, and K, giving sprouts the clear victory here, especially with much higher margins of difference (e.g. 58x more vitamin A, as well as 7x more vitamin C, and 10x more vitamin K).
When it comes to minerals, artichoke has more copper, magnesium, phosphorus, and zinc, while Brussels sprouts have more iron, manganese, potassium, and selenium, resulting in a 4:4 tie, and the small margins of difference are mostly comparable, with the exception that sprouts have 8x more selenium. So, Brussels sprouts win this category very marginally on that tie-breaker.
Adding up the sections we see that macros and minerals gave a small win each to artichoke and sprouts respectively, while the vitamins category was an overwhelming win for sprouts, so—with this deciding factor in mind—sprouts win the day today.

Grain Brain – by Dr. David Perlmutter
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.
If you’re a regular 10almonds reader, you probably know that refined flour, and processed food in general, is not great for the health. So, what does this book offer more?
Dr. Perlmutter sets out the case against (as the subtitle suggests) wheat, carbs, and sugar. Yes, including wholegrain wheat, and including starchy vegetables such as potatoes and parsnips. Fruit does also come under scrutiny, a clear distinction is made between whole fruits and juices. In the latter case, the lack of fiber (along with the more readily absorbable liquid state) allows for those sugars to zip straight into our blood.
The book includes lots of stats and facts, and many study citations, along with infographics and clear explanations.
If the book has a weakness, it’s when it forgets to clarify something that was obvious to the author. For example, when he talks about our ancestors’ diets being 75% fat and 5% carbs, he neglects to mention that this is 75% by calorie count, not by mass or volume. This makes a huge difference! It’s the difference between a fat-guzzling engine, and someone who eats mostly fruit and oily nuts but also some very high-fat meat/organs.
The book’s strengths, on the other hand, are found in its explanation, backed by good science, of what wheat, along with excessive carbohydrates (especially sugar) can do to our body, including (and most focusedly, hence the title) our brain, leading the way to not just obvious metabolic disorders like diabetes, but also inflammatory diseases like Alzheimer’s.
Bottom line: you don’t have to completely revamp your diet if it’s working for you, but data is data, and this book has lots, making it well-worth a read.

Ageless Athletes – by Dr. Jim Madden
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.
This is an approach to strength and fitness training specifically for the 50+ crowd, and/but even more specifically for the 50+ crowd who do not wish to settle for mediocrity. In short, it’s for those who not only wish to stay healthy and have good mobility, but also who wish to be and remain athletic.
It does not assume extant athleticism, but nor does it assume complete inexperience. It provides a fairly ground-upwards entry to a training program that then quickly proceeds to competitive levels of athleticism.
The author himself details his own journey from being in his 30s, overweight and unfit, to being in his 50s and very athletic, with before and after photos. Granted, those are 20 years in between, but all the same, it’s a good sign when someone gets stronger and fitter with age, rather than declining.
The style of the book is quite casual, and/but after the introductory background and pep talk, is quite pragmatic and drops the additional fluff. In particular, older readers may enjoy the “Old Workhorse” protocol, as a tailored measured progression system.
In terms of expected equipment by the way, some is bodyweight and some is with weights; kettlebells in particular feature strongly, since this is about functional strength and not bodybuilding.
In the category of criticism, he does refer to his other books and generally assumes the reader is reading all his work, so it may not be for everyone as a standalone book.
Bottom line: if you’re 50+ and are wondering how to gain/maintain a high level athleticism, this book can definitely help with that.

Never Too Old?
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.
Age Limits On Exercise?
In Tuesday’s newsletter, we asked you your opinion on whether we should exercise less as we get older, and got the above-depicted, below-described, set of responses:
- About 42% said “No, we must keep pushing ourselves, to keep our youth“
- About 29% said “Only to the extent necessary due to chronic conditions etc”
- About 29% said “Yes, we should keep gently moving but otherwise take it easier”
One subscriber who voted for “No, we must keep pushing ourselves, to keep our youth“ wrote to add:
❝I’m 71 and I push myself. I’m not as fast or strong as I used to be but, I feel great when I push myself instead of going through the motions. I listen to my body!❞
~ 10almonds subscriber
One subscriber who voted for “Only to the extent necessary due to chronic conditions etc” wrote to add:
❝It’s never too late to get stronger. Important to keep your strength and balance. I am a Silver Sneakers instructor and I see first hand how helpful regular exercise is for seniors.❞
~ 10almonds subscriber
One subscriber who voted to say “Yes, we should keep gently moving but otherwise take it easier” wrote to add:
❝Keep moving but be considerate and respectful of your aging body. It’s a time to find balance in life and not put yourself into a positon to damage youself by competing with decades younger folks (unless you want to) – it will take much longer to bounce back.❞
~ 10almonds subscriber
These will be important, because we’ll come back to them at the end.
So what does the science say?
Endurance exercise is for young people only: True or False?
False! With proper training, age is no barrier to serious endurance exercise.
Here’s a study that looked at marathon-runners of various ages, and found that…
- the majority of middle-aged and elderly athletes have training histories of less than seven years of running
- there are virtually no relevant running time differences (p<0.01) per age in marathon finishers from 20 to 55 years
- after 55 years, running times did increase on average, but not consistently (i.e. there were still older runners with comparable times to the younger age bracket)
The researchers took this as evidence of aging being indeed a biological process that can be sped up or slowed down by various lifestyle factors.
See also:
Age & Aging: What Can (And Can’t) We Do About It?
this covers the many aspects of biological aging (it’s not one number, but many!) and how our various different biological ages are often not in sync with each other, and how we can optimize each of them that can be optimized
Resistance training is for young people only: True or False?
False! In fact, it’s not only possible for older people, but is also associated with a reduction in all-cause mortality.
Specifically, those who reported strength-training at least once per week enjoyed longer lives than those who did not.
You may be thinking “is this just the horse-riding thing again, where correlation is not causation and it’s just that healthier people (for other reasons) were able to do strength-training more, rather than the other way around?“
…which is a good think to think of, so well-spotted if you were thinking that!
But in this case no; the benefits remained when other things were controlled for:
❝Adjusted for demographic variables, health behaviors and health conditions, a statistically significant effect on mortality remained.
Although the effects on cardiac and cancer mortality were no longer statistically significant, the data still pointed to a benefit.
Importantly, after the physical activity level was controlled for, people who reported strength exercises appeared to see a greater mortality benefit than those who reported physical activity alone.❞
See the study: Is strength training associated with mortality benefits? A 15 year cohort study of US older adults
And a pop-sci article about it: Strength training helps older adults live longer
Closing thoughts
As it happens… All three of the subscribers we quoted all had excellent points!
Because in this case it’s less a matter of “should”, and more a selection of options:
- We (most of us, at least) can gain/regain/maintain the kind of strength and fitness associated with much younger people, and we need not be afraid of exercising accordingly (assuming having worked up to such, not just going straight from couch to marathon, say).
- We must nevertheless be mindful of chronic conditions or even passing illnesses/injuries, but that goes for people of any age
- We also can’t argue against a “safety first” cautious approach to exercise. After all, sure, maybe we can run marathons at any age, but that doesn’t mean we have to. And sure, maybe we can train to lift heavy weights, but if we’re content to be able to carry the groceries or perhaps take our partner’s weight in the dance hall (or the bedroom!), then (if we’re also at least maintaining our bones and muscles at a healthy level) that’s good enough already.
Which prompts the question, what do you want to be able to do, now and years from now? What’s important to you?
