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!

10almonds Subcribers Take The Wheel!
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.
❓ Q&A With 10almonds Subscribers!
Q: What kind of salt is best for neti pots?
A: Non-iodised salt is usually recommended, but really, any human-safe salt is fine. By this we mean for example:
- Sodium chloride (like most kitchen salts),
- Potassium chloride (as found in “reduced sodium” kitchen salts), or
- Magnesium sulfate (also known as epsom salts).
Q: You talked about spearmint as reducing testosterone levels, what about ginseng for increasing them?
A: Hormones are complicated and often it’s not a simple matter of higher or lower levels! It can also be a matter of…
- how your body converts one thing into another
- how your body responds (or not) to something according to how the relevant hormone’s receptors are doing
- …and whether there’s anything else blocking those receptors.
All this to say: spearmint categorically is an anti-androgen, but the mechanism of action remains uncertain.
Panax ginseng, meanwhile, is one of the most well-established mysteries in herbal medicine.
Paradoxically, it seems to improve both male and female hormonal regulation, despite being more commonly associated with the former.
- It doesn’t necessarily increase or decrease testosterone or estrogen levels (but it can, even if indirectly)
- It does improve sexual function
- …and alleviates symptoms associated with conditions as varied as:
- Late-onset hypogonadism (common for men during the andropause)
- Benign prostate hyperplasia (again common for men during the andropause)
- …and also counteracts unwanted side-effects of finasteride. Finasteride is often taken by men as a hair loss remedy or, less often but critically, in the case of an enlarged prostate.
But it also…
- Alleviates symptoms of PCOS (polycystic ovary syndrome, which effects around 20% of women)
- May even be an effective treatment for PCOS (rat model only so far)
- It also may improve female reproductive fertility more generally (the studies are down to fruit flies now though)
Bottom line: Panax ginseng is popularly taken to improve natural hormone function, a task at which it appears to excel.
Scientists are still working out exactly how it does the many things it appears to do.
Progress has been made, and it clearly is science rather than witchcraft, but there are still far more unanswered questions than resolved ones!
Q: I like that the quizzes (I’ve done two so far) give immediate results , with no “give us your email to get your results”. Thanks!
A: You’re welcome! That’s one of the factors that influences what things we include here! Our mission statement is “to make health and productivity crazy simple”, and the unwritten part of that is making sure to save your time and energy wherever we reasonably can!
Q: Do you know if adrafanil is as good as modafinil? It seems to be a lot cheaper for the same result?
A: Adrafinil is the pro-drug of modafinil. What this means is that if you take it, your own liver will use it to make modafinil inside you. So the end result is chemically the same drug.
As to whether it’s as good, it depends what you need. It’s worth noting that anything that taxes liver function can be harmful if you take too much, and/or your liver is already strained for some reason.
If in doubt, consult a doctor! And if it’s something that’s accessible to you, a recent lipids test (a kind of blood test that checks your liver health) is always a good thing to have.
Q: Would love to see your take on polyphasic sleep!
A: Watch this space

Level-Up Your Fiber Intake! (Without Difficulty Or Discomfort)
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.
Why You’re Probably Not Getting Enough Fiber (And How To Fix It)
First things first… How much fiber should we be eating?
- The World Health Organization recommends we each get at least 25g of fiber per day:
- A more recent meta-review of studies, involving thousands of people and decades of time, suggests 25–29g is ideal:
- The British Nutritional Foundation gives 30g as the figure:
- The US National Academy of Sciences’ Institute of Medicine recommends 21g–38g per day, depending on age and sex:
- A large study last year gave 30–40g as the figure:
*This one is also a great read to understand more about the “why” of fiber
Meanwhile, the average American gets 16g of fiber per day.
So, how to get more fiber, without piling on too many carbs?
Foods that contain fiber generally contain carbs (there’s a limit to how much celery most people want to eat), so there are two key ideas here:
- Getting a good carb:fiber ratio
- Making substitutions that boost fiber without overdoing (or in some case, even changing) carbs
Meat → Lentils
Well-seasoned lentils can be used to replaced ground beef or similar. A cup of boiled lentils contains 18g of fiber, so you’re already outdoing the average American’s daily total.
Meat → Beans
Black beans are a top-tier option here (15g per cup, cooked weight), but many kinds of beans are great.
Chicken/Fish → Chickpeas
Yes, chicken/fish is already meat, but we’re making a case for chickpeas here. Cooked and seasoned appropriately, they do the job, and pack in 12g of fiber per cup. Also… Hummus!
Bonus: Hummus, eaten with celery sticks.
White pasta/bread → Wholewheat pasta/bread
This is one where “moderation is key”, but if you’re going to eat pasta/bread, then wholewheat is the way to go. Fiber amounts vary, so read labels, but it will always have far more than white.
Processed salty snacks → Almonds and other nuts
Nuts in general are great, but almonds are top-tier for fiber, amongst other things. A 40g handful of almonds contains about 10g of fiber.
Starchy vegetables → Non-starchy vegetables
Potatoes, parsnips, and their friends have their place. But they cannot compete with broccoli, peas, cabbage, and other non-starchy vegetables for fiber content.
Bonus: if you’re going to have starchy vegetables though, leave the skins on!
Fruit juice → Fruit
Fruit juice has had most, if not all, of its fiber removed. Eat an actual juicy fruit, instead. Apples and bananas are great options; berries such as blackberries and raspberries are even better (at around 8g per cup, compared to the 5g or so depending on the size of an apple/banana)
Processed cereals → Oats
5g fiber per cup. Enough said.
Summary
Far from being a Herculean task, getting >30g of fiber per day can be easily accomplished by a lentil ragù with wholewheat pasta.
If your breakfast is overnight oats with fruit and some chopped almonds, you can make it to >20g already by the time you’ve finished your first meal of the day.
Enjoy!

The Epigenetics Revolution – by Dr. Nessa Carey
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 enjoyed the book “Inheritance” that we reviewed a couple of days ago, you might love this as a “next read” book. But you can also just dive straight in here, if you like!
This one, as the title suggests, focuses entirely on epigenetics—how our life events can shape our genetic expression, and that of our descendants. Or to look at it in the other direction, how our genetic expression can be shaped by the life experiences of, for example, our grandparents.
The style of this book is very much pop-science, but contains a lot of information from hard science throughout. We learn not just about longitudinal population studies as one might expect, but also about the intricacies of DNA methylation and histone modifications, for example.
Depending on your outlook, you may find some of this very bleak (“great, I am shackled by what my grandparents did”) or very optimism-inducing (“oh wow, I’m not nearly so constrained by genetics as I thought; this stuff is so malleable!”). This is also the same author who wrote “Hacking The Code of Life“, by the way, but we’ll review that another day.
Bottom line: this book is the best one-shot primer on epigenetics that this reviewer has read (you may be wondering how many that is, and the answer is… about seven or so? I’m not good at counting).

What Happens To Your Body When You Eat Raw Garlic Everyday
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.
Garlic’s benefits are not all in its most talked-about active compound, allicin (some are in other parts of the garlic), but the allicin is certainly very potent. However, allicin breaks down easily, which means that cooking reduces its value greatly, meaning that for health purposes, it is best consumed raw. Pickled garlic cloves are great, by the way, and you should try them if you haven’t already.
Garlic’s benefits (aside from being delicious)
Benefits that can be expected include:
- Boosts immunity: allicin enhances white blood cell function, helping fight off colds and flu
- Supports heart health: lowers blood pressure, reduces cholesterol, and prevents blood clots, reducing the risk of heart disease and stroke
- Anti-cancer properties: it contains sulfur compounds that may inhibit cancer cell growth, particularly in the digestive system
- Improves digestion: stimulates digestive enzymes and promotes gut health, helping with better nutrient absorption and digestion
- Enhances brain function: antioxidants in garlic are neuroprotective, reducing cognitive decline
- Good for your skin: its antibacterial and anti-inflammatory properties can help improve skin health
- Regulates blood sugar levels: helps regulate blood sugar and improves insulin sensitivity
- Anti-inflammatory effects: contains compounds that reduce inflammation, helping to combat inflammatory diseases such as arthritis
- Supports weight loss: stimulates metabolism, suppresses appetite, and helps break down fats, aiding in weight management
- May protect against osteoporosis: increases estrogen levels in women, potentially reducing the risk of osteoporosis (no effect on estrogen levels if you don’t have ovaries)
The daily dose that this video recommends is 1–2 cloves of garlic or 3600mg of aged garlic extract as a supplement.

5 Ways To Beat Cancer (And Other Diseases)
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.
A Systematic Approach To Healthy Eating
This is Dr. William Li. He’s a physician, cancer researcher, and educator. He also founded the Angiogenesis Foundation back in 1994.
We recently reviewed one of his books, “Eat To Beat Disease”.
He has another book that we haven’t reviewed at time of writing, “Eat To Beat Your Diet“, which you might like to check out.
What does he want us to know?
He wants us to know how to eat to beat cancer and other diseases, by means of five specific angles:
Angiogenesis
This is about replacing blood vessels, which of course happens all the time, but it becomes a problem when it is feeding a cancer in the process.
Here, based on Dr. Li’s work, is what can be done about it:
A List of Anti-Angiogenic Foods for a Cancer-Fighting Diet
Regeneration
Generally speaking, we want to replace healthy cells early, because if we wait until they get damaged, then that damage will be copied forwards. As well as intermittent fasting, there are other things we can do to promote this—even, Dr. Li’s research shows, for stem cells:
Doctor’s Tip: Regeneration (stem cells)—one of your body’s five defense systems
Microbiome health
Healthy gut, healthy rest of the body. We’ve written about this before:
Making Friends With Your Gut (You Can Thank Us Later)
DNA protection
DNA gets unravelled and damaged with age, the telomere caps get shorter, and mistakes get copied forward. So there more we can protect our DNA, the longer we can live healthily. There are many ways to do this, but Dr. Li was one of the first to bring to light the DNA-protecting benefits of kiwi fruit:
Immunity
Paradoxically, what’s good for your immune system (making it stronger) also helps to protect against autoimmune diseases (for most people, for the most part).
In short: it’s good to have an immune system that’s powerful not just in its counterattacks, but also in its discerning nature. There are dietary and other lifestyle approaches to both, and they’re mostly the same things:

6 Signs Of A Heart Attack… A Month In Advance
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 people know the signs of a heart attack when it’s happening, but how about before it’s too late to avoid it?
The signs
- Unusual fatigue: persistent tiredness that doesn’t improve with rest
- Shortness of breath: unexplained breathlessness during light activities or rest, which can be caused by fluid buildup in the lungs (because the heart isn’t circulating blood as well as it should)
- Chest discomfort: pain, pressure, tightness, or aching in the chest due to reduced blood flow to the heart muscle—often occurring during physical exertion or emotional stress
- Frequent indigestion: means that heartburn could be heart-related! This is about persistently reoccurring discomfort or pain in the upper abdomen
- Sleep disturbances: difficulties falling asleep, staying asleep, or waking up abruptly
- Excessive sweating: unexplained cold sweats or sudden sweating without physical exertion or excessive heat, can be a response to the decreased oxygen levels caused by less efficient blood flow
Note: this is a list of warning signs, not a diagnostic tool. Any or even all of these could be caused by something else. Just, don’t ignore the signs and do get yourself checked out.
