It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
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 😎
❝I read about probiotics and got myself some from amazon but having started them, now I have a lot of gas, is this normal?❞
As Tom Jones would say: it’s not unusual.
However, it’s also not necessary, and it is easy enough to get past!
And probiotics certainly have their place; see: How Much Difference Do Probiotic Supplements Make, Really?
What’s going on with your gas is…
We interrupt this article to bring back attention to our regular legal/medical disclaimer; please do remember that we can only speak in general health terms, cannot diagnose you, nor make any firm assurances about your health, nor prescribe treatment. What we can do is share information that we hope is educational, and if it helps you, so much the better. Always speak to your own doctor if you have concerns about your health.
Now, back to the article,,,
What’s going on with your gas is most probably what happens for a lot of people: you’ve just put a lot of bacteria into your gut, and congratulations, they survived (which is definitely not a given, more on that later, but their survival is what you wanted), and they are now thriving sufficiently that the output of their respiratory processes is tangible to you—in the form of abdominal bloating/gas.
Because your gut is a semi-closed system (literally there’s an opening at both ends, but it’s mostly quite self-contained in terms of its ecosystem, unless you have leaky gut syndrome, which is Very Bad™), this will generally fix itself within a few days at most—perhaps it even has by the time you’re reading this.
How does it fix itself you wonder? Because there’s only enough resources to sustain so many bacteria, what happens when we take a probiotic supplement (or food) is initially an overload of more bacteria than the gut can support (because unless you recently took antibiotics, the gut is pretty much always running at maximum capacity, because the bacteria there have no evolutionary reason to leave room for newcomers; they just multiply as best they can until the resources run out), and then the excess (i.e., those that are in excess of how many your gut can support) will die, and then the numbers will be back to normal.
Note: the numbers will be back to normal. However, that doesn’t mean the probiotics did nothing—what you’ve done is add diversity, and specifically, you’ve made it so that percentage-wise, you now have slightly more “good” bacteria in the balance than you did previously.
So, unless there are factors out of the ordinary: this is all usually self-correcting quite quickly.
Tips to make things go as smoothly as possible
Firstly, pay attention to recommended doses. If you take one, and think “that was delicious; I’ll have six more” then the initial effect will be a lot more than six times stronger, because of the nature of how bacteria multiply (i.e. exponentially) within minutes of reaching your gut.
Again, this will normally self-correct, but there’s no reason to cause yourself discomfort unnecessarily.
Secondly, if you take probiotics and do not get even a little gas or abdominal bloating even just a little bit, even just briefly… Then probably one of two things happened:
- The probiotics were dead on arrival (i.e. the supplement was a dud, or a “live culture” product in fact died before it got to you)
- The probiotics were fine, but your gut wasn’t prepared for them, and they died upon arrival
The latter happens a lot, especially if the current gut health is not good. What your probiotics need to survive (and bear in mind, because of their life cycle, they need this in minutes of arrival, which is their multiply-or-die-out window), is:
- Fiber, especially insoluble fiber
- In a place they can get at it (i.e. it was the most recent thing you ate, and is not several feet further down your intestines)
- Not too crowded with competitors (i.e. you just ate it, not last night)
Thus, it can be best to take probiotics on a mostly-empty stomach after enjoying a fibrous snack.
See also: What Do The Different Kinds Of Fiber Do? 30 Foods That Rank Highest
And for that matter: Stop Sabotaging Your Gut ← this covers some common probiotics mistakes/problems
If you’d rather take them on an entirely empty stomach, look for probiotic supplements that come with their own prebiotic fiber (usually inulin); these are often marketed as “symbiotics”.
We don’t sell them, but here’s an example product on Amazon for your convenience 😎
Another thing to bear in mind is that there is (unless your case is unusual) no reason to take the same kind of probiotic for more than one course (i.e. one container of however many servings it has). This is because one of two things will be the case:
- The probiotic worked, in which case, you now have thriving colonies of the bacterial species that that supplement provided
- The probiotic didn’t work, in which case, why buy that one again?
So, if supplementing with probiotics, it can be good to do so with new brand each time, with a gap in between each for your gut to get used to the new order of things.
Finally, if you’re making any drastic dietary change, likely this will result in similar gut disturbances.
In particular, if you are moving away from foods that feed C. albicans (the bad fungus that puts holes in your gut), then it will object strongly, cause you to crave sugar/flour/alcohol/etc, give you mood swings, and generally remind you that it has its roots firmly embedded in your nervous system. If that happens, don’t listen to it; it’s just its death throes and it’ll quieten down soon.

Pistachios vs Walnuts – 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 pistachios to walnuts, we picked the pistachios.
Why?
Pistachios have more protein and fiber, while walnuts have more fat (though the fats are famously healthy, the same is true of the fats in pistachios).
In the category of vitamins, pistachios have several times more* of vitamins A, B1, B6, C, and E, while walnuts boast only a little more of vitamin B9. They are approximately equal on other vitamins they both contain.
*actually 25x more vitamin A, but the others are 2x, 3x, 4x more.
When it comes to minerals, things are more even; pistachios have more iron, phosphorus, potassium, and selenium, while walnuts have more copper, magnesium, manganese, and zinc. So this category’s a tie.
So given two clear wins for pistachios, and one tie, it’s evident that pistachios win the day.
However! Do enjoy both of these nuts; we often mention that diversity is good in general, and in this case, it’s especially true because of the different mineral profiles, and also because in terms of the healthy fats that they offer, pistachios offer more monounsaturated fats and walnuts offer more polyunsaturated fats; both are healthy, just different.
They’re about equal on saturated fat, in case you were wondering, as it makes up about 6% of the total fats in both cases.

What Mattress Is Best, By Science?
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 Foundations of Good Sleep
You probably know the importance of good sleep for good health. If not, here’s a quick refresher:
- Why You Probably Need More Sleep
- How Sleep-Deprived Are You, Really?
- The 6 Dimensions Of Sleep (And Why They Matter)
You should also definitely check out this quite famous book on the topic:
Why We Sleep – by Dr Matthew Walker
What helps, to get that good sleep
We’ve covered this a little before too, for example:
- Safe Effective Sleep Aids For Seniors
- Sleep Better With Better Air
- How To Nap Like A Pro (No More “Sleep Hangovers”!)
How to level-up from there
One of the biggest barriers to good sleep for many people is obstructive sleep apea:
Healthier, Natural Sleep Without Obstruction!
We covered (in the above article) a whole lot of ways of mitigating/managing obstructive sleep apnea. One of the things we mentioned as beneficial was avoiding sleeping on one’s back, and this is something Mayo Clinic’s Dr. Somers agreed with:
Back Sleeping, And Sleeping Differently After 50
“But side-sleeping is uncomfortable”
If this is you, then chances are you have the wrong mattress.
If your mattress is too firm, you can get around it by using this “five pillow” method:

If your mattress is too soft, then sorry, you really just have to throw that thing out and start again.
The Goldilocks mattress
While different people will have different subjective preferences, the science is quite clear on what is actually best for people’s spines. As this review of 39 qualified scholarly articles concluded:
❝Results of this systematic review show that a medium-firm mattress promotes comfort, sleep quality and rachis alignment❞
~ Dr. Gianfilippo Caggiari et al.
Read in full: What type of mattress should be chosen to avoid back pain and improve sleep quality? Review of the literature
Note: to achieve “medium-firm” that remains “medium firm” has generally been assumed to require a memory-foam mattress.
How memory-foam works: memory-foam is a moderately thermosoftening material, designed to slightly soften at the touch of human body temperature, and be firmer at room temperature. This will result in it molding itself to the form of a human body, providing what amounts to personalized support for your personal shape and size, meaning your spine can stay exactly as it’s supposed to when you’re sleeping on your side, instead of (for example) your hips being wider meaning that your lumbar vertebrae are raised higher than your thoracic vertebrae, giving you the equivalent of a special nocturnal scoliosis.
It will, therefore, stop working if
- the ambient temperature is comparable to human body temperature (as happens in some places sometimes, and increasingly often these days)
- you die, and thus lose your body temperature (but in that case, your spinal alignment will be the least of your concerns)
Here’s a good explanation of the mechanics of memory foam from the Sleep Foundation:
Sleep Foundation | What is Memory Foam?
An alternative to memory foam?
If you don’t like memory foam (one criticism is that it doesn’t allow good ventilation underneath the body), there is an alterative, the grid mattress.
It’s very much “the new kid on the block” and the science is young for this, but for example this recent (April 2024) study that concluded:
❝The grid mattress is a simple, noninvasive, and nonpharmacological intervention that improved adults sleep quality and health. Controlled trials are encouraged to examine the effects of this mattress in a variety of populations and environments.❞
~ Dr. Heather Hausenblas et al.
Read in full: Effectiveness of a grid mattress on adults’ sleep quality and health: A quasi-experimental intervention study
However, that was a small (n=39) uncontrolled (i.e. there was no control group) study, and the conflict of interest statement is, well, interesting:
❝Heather A. Hausenblas, Stephanie L. Hooper, Martin Barragan, and Tarah Lynch declare no conflict of interest. Michael Breus served as a former consultant for Purple, LLC.❞
~ Ibid.
…which is a fabulous way of distracting from the mention in the “Acknowledgements” section to follow, that…
❝Purple, LLC, provided financial support for the study❞
~ Ibid.
Purple is the company that invented the mattress being tested. So while this doesn’t mean the study is necessarily dishonest and/or corrupt, it does at the very least raise a red flag for a potential instance of publication bias (because Purple may have funded multiple studies and then pulled funding of the ones that weren’t going their way).
If you are interested in Purple’s mattress and how it works, you can check it out here ← this is a link for your interest and information; not an advertisement or an endorsement. We look forward to seeing more science for this though, and echo their own call for randomized controlled trials!
Summary
Sleep is important, and while it’s a popular myth that we need less as we get older, the truth is that we merely get less on average, while still needing the same amount.
A medium-firm memory-foam mattress is a very good, well-evidenced way to support that (both figuratively and literally!).
A grid mattress is an interesting innovation, and/but we’d like to see more science for it.
Take care!

10almonds Subcribers Take The Wheel!

❓ 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

Robert F. Kennedy Jr says vitamin A protects you from deadly measles. Here’s what the study he cites actually says
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.
Robert F. Kennedy Jr, who oversees the health of more than 340 million Americans, says vitamin A can prevent the worst effects of measles rather than urging more people to get vaccinated.
In an opinion piece for Fox News, the US health secretary said he was “deeply concerned” about the current measles outbreak in Texas. However, he said the decision to vaccinate was a “personal one” and something for parents to discuss with their health-care provider.
Kennedy mentioned updated advice from the Centers for Disease Control (CDC) to treat measles with vitamin A. He also cited a study he said shows vitamin A can reduce the risk of dying from measles.
Here’s what the vitamin A study actually says and why public health officials are so concerned about Kennedy’s latest statement.
RobsPhoto/Shutterstock Why is a measles outbreak so worrying?
Measles is a highly contagious disease caused by a virus. It spreads easily including when an infected person breathes, coughs or sneezes.
Measles initially infects the respiratory tract and then the virus spreads throughout the body. Symptoms include a high fever, cough, red eyes, runny nose and a rash all over the body.
Measles can also be severe, can cause complications including blindness and swelling of the brain, and can be fatal. Measles can affect anyone but is most common in children.
The Texan health department has confirmed 150-plus cases of measles and one death of an unvaccinated child during the current outbreak. While this is by far the largest measles outbreak in the US in 2025, the CDC has reported smaller outbreaks in several other states so far this year.
Why vitamin A?
Vitamin A is essential for our overall health. It has many roles in the body, from supporting our growth and reproduction, to making sure we have healthy vision, skin and immune function.
Foods rich in vitamin A or related molecules include orange, yellow and red coloured fruits and vegetables, green leafy vegetables, as well as dairy, egg, fish and meat. You can take it as a supplement.
Vitamin A can also be used therapeutically. In other words, doctors may prescribe vitamin A to treat a deficiency. Vitamin A deficiency has long been associated with more severe cases of infectious disease, including measles. Vitamin A boosts immune cells and strengthens the respiratory tract lining, which is the body’s first defence against infections.
Because of this, the CDC has recently said vitamin A can also be prescribed as part of treatment for children with severe measles – such as those in hospital – under doctor supervision.
One key message from the CDC’s advice is that people are already sick enough with measles to be in hospital. They’re not taking vitamin A to prevent catching measles in the first place.
The other key message is vitamin A is taken under medical supervision, under specific circumstances, where patients can be closely monitored to prevent toxicity from high doses.
Vitamin A toxicity can cause birth defects and increase the risk of fractures in elderly people. Vitamin A and beta-carotene (which the body turns into vitamin A) from supplements may also increase your risk of cancer, especially if you smoke.
Taking too much vitamin A can lead to toxicity and cause birth defects. ChameleonsEye/Shutterstock How about the study Kennedy cites?
Kennedy cites and links to a 2010 study, a type known as a systematic review and meta-analysis. Researchers reviewed and analysed existing studies, which included ones that looked at the effectiveness of vitamin A in preventing measles deaths.
They found three studies that looked at vitamin A treatment by specific dose. There were different doses depending on the age of the children, measured in IU (international units). Having two doses of vitamin A (200,000IU for children over one year of age or 100,000IU for infants below one year) reduced mortality by 62% compared to children who did not have vitamin A.
The 2010 study did not show vitamin A reduced your risk of getting measles from another infected person. To my knowledge no study has shown this.
To be fair, Kennedy did not say that vitamin A stops you from catching measles from another infected person. Instead, he used the following vague statement:
Studies have found that vitamin A can dramatically reduce measles mortality.
It’s easy to see how a reader could misinterpret this as “take vitamin A if you want to avoid dying from measles”.
We know what works – vaccines
The World Health Organization recommends all children receive two doses of measles vaccine.
The CDC states two doses of the measles vaccine (measles-mumps-rubella or MMR vaccine) is 97% effective against getting measles. This means out of every 100 people who are vaccinated only three will get it, and this will be a milder form.
But these facts were missing from Kennedy’s statement. Should we be surprised? Kennedy is well known for his vaccine sceptism and for undermining vaccination efforts, including for the measles vaccine.
As Sue Kressly, president of the American Academy of Pediatrics, told the Washington Post:
relying on vitamin A instead of the vaccine is not only dangerous and ineffective […] it puts children at serious risk.

Carrot vs Kale – 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 carrot to kale, we picked the kale.
Why?
These are both known as carotene-containing heavyweights, but kale emerges victorious:
In terms of macros, carrot has more carbs while kale has more protein and fiber. An easy win there for kale.
When it comes to vitamins, both are great! But, carrots contain more of vitamins A, B5, and choline, whereas kale contains more of vitamins B1, B2, B3, B6, B9, C, E, and K. And while carrot’s strongest point is vitamin A, a cup of carrots contains around 10x the recommended daily dose of vitamin A, whereas a cup of kale contains “only” 6x the recommended daily dose of vitamin A. So, did we really need the extra in carrots? Probably not. In any case, kale already won on overall vitamin coverage, by a long way.
In the category of minerals, kale again sweeps. On the one hand, carrots contain more sodium. On the other hand, kale contains a lot more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. Not a tricky choice!
But don’t be fooled: carrots really are a nutritional powerhouse and a great food. Kale is just better—nutritionally speaking, in any case. If you’re making a carrot cake, please don’t try substituting kale; it will not work 😉

The Metabolism Reset Diet – by Alan Christianson
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 liver is an incredible organ that does a very important job, but what’s not generally talked about is how we can help it… Beyond the obvious “try to not poison it too much with alcohol, tobacco, etc”. But what can we do that’s actually positive for it?
That’s what Alan Christianson offers in this book.
Now, usually when someone speaks of a “four week cleanse” as this book advertises on its front cover, it’s a lot of bunk. The liver cleanses itself, and the liver and kidneys between them (along with some other organs and processes) detoxify your body for you. No amount of celery juice will do that. However, this book does better than that:
What it’s about, is not really about trying to do a “detox” at all, so much as supporting your liver function by:
- Giving your liver what it needs to regenerate (mostly: protein)
- Not over-taxing your liver while it does so
The liver is a self-regenerating organ (the mythological story of Prometheus aside, here in real life it can regenerate up to 80% of itself, given the opportunity), so whatever the current state of your liver, it’s probably not too late to fix it.
Maybe you’ve been drinking a little too much, or maybe you’ve been taking some meds that have hobbled it a bit (some medications strain the liver rather), or maybe your diet hasn’t been great. Christianson invites you to draw a line under that, and move forwards:
The book gives an overview of the science involved, and explains about the liver’s role in metabolism (hence the promised weight loss benefits) and our dietary habits’ impact on liver function. This is about what we eat, and also about when we eat it, and how and when our body metabolizes that.
Christianson also provides meal ideas and recipes. If we’re honest (and we always are), the science/principles part of the book are worth a lot more than the meal-plan part of the book, though.
In short: a great book for understanding how the liver works and how we can help it do its job effectively.
