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 😎
❝Skip the video & tell more about olive oil please.❞
We love requests!
We can’t really do anti-requests (e.g. “skip the video”) because for every one person who doesn’t care for one particular element of the newsletter, there will be thousands who do—and indeed, the video segment is a popular one, so it will certainly remain.
However! Let us reassure you that you personally are not obliged to watch the video if you don’t want to 🙂 In fact, our general hope with 10almonds is that there will be at least one feature that is of value to each reader, each day.
Writer’s note: I’m a very bookish person, and in honesty do not love videos personally either. You know what I do love though? Olive oil. So let’s get onto that 😎
Why olive oil?
Let’s quickly address the taste/culinary side of things first, and then spend more time on the health aspects. Olive oil’s strong punchy flavor (as oils go, anyway) makes it a big winner with those of us who love strong punchy flavors. However, it does mean that it can overwhelm some more delicate dishes if one isn’t careful, meaning that it’s not perfect for everything all the time.
Healthwise, olive oil is one of the healthiest oils around, along with avocado oil. In fact, we compared them previously:
Avocado Oil vs Olive Oil – Which is Healthier?
…and it’s worth noting that their (excellent) lipids profiles are very similar, meaning that the main factor between them is that olive oil usually retains vitamins that avocado oil doesn’t.
Meanwhile, another popular contender for “healthy oil” is coconut oil, but this doesn’t have nearly as unambiguously good a lipids profile, because of coconut oil’s high saturated fat content—though lauric acid can have a cardioprotective effect, so the jury is out on that one:
Olive Oil vs Coconut Oil – Which is Healthier?
Interestingly, this article from The Conversation considered seed oils (canola, sunflower, sesame) to be next-best options:
I can’t afford olive oil. What else can I use?
…but it’s worth noting that the way those seed oils are made varies a lot from country to country, and can affect their health impact considerably.
It’s not just about the fats
Olives, especially green olives with their stronger more pungent flavor, are rich in assorted polyphenols that have many health-giving properties:
Black Olives vs Green Olives – Which is Healthier
…and olive oil is almost always made from green olives. Note that while we picked black olives in the above comparison, that’s mainly because green olives are “cured” for longer and thus are much higher in sodium… Which, guess what, isn’t in olive oil, so with olive oil we can enjoy all of the polyphenols with almost none of the sodium!
Let’s talk virginity
When it comes to olive oil, definitely not everything labelled as olive oil in the supermarket is of the same quality. Mostly, however, it’s not whether it’s “extra virgin” (i.e. the oil from the first mechanical pressing) or not that actually makes the biggest health difference, so much as that olive oils are often adulterated with other cheaper oils, so it’s important to check labels for that, even when they say “extra virgin”, in case it’s something like:
a blend of
EXTRA VIRGIN OLIVE OIL
and other oils
We talk about this, and the various different levels of quality of olive oil and how you can tell them apart for yourself in the supermarket (and be wise to the ways they may try to trick you), here:
What to enjoy it with?
Olive oil is the single largest source of fat in the Mediterranean diet, and by that we mean not just “food that is eaten in the Mediterranean”, but rather, the well-defined dietary approach that has for a long time now been considered “the gold standard” of what a healthy diet looks like, scientifically. You can read more about what is and isn’t included in the definition, here:

Fluoride Toothpaste vs Non-Fluoride Toothpaste – 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 fluoride toothpaste to non-fluoride toothpaste, we picked the fluoride.
Why?
Fluoride is indeed toxic; that’s why it’s in toothpaste (to kill things; namely, bacteria whose waste products would harm our teeth). However, we are much bigger than those bacteria.
Given the amount of fluoride in toothpaste (usually under 1mg per strip of toothpaste to cover a toothbrush head), the amount that people swallow unintentionally (about 1/20th of that, so about 0.1mg daily if brushing teeth twice daily), and the toxicity level of fluoride (32–64mg/kg), then even if we take the most dangerous ends of all those numbers (and an average body size), to suffer ill effects from fluoride due to brushing your teeth, would require that you brush your teeth more than 23,000 times per day.
Alternatively, if you were to ravenously eat the toothpaste instead of spitting it out, you’d only need to brush your teeth a little over 1,000 times per day.
All the same, please don’t eat toothpaste; that’s not the message here.
However! In head-to-head tests, fluoride toothpaste has almost always beaten non-fluoride toothpaste.
Almost? Yes, almost: hydroxyapatite performed equally in one study, but that’s not usually an option on as many supermarket shelves.
We found some on Amazon, though, which is the one we used for today’s head-to-head. Here it is:
However, before you rush to buy it, do be aware that the toxicity of hydroxyapatite appears to be about twice that of fluoride:
Scientific Committee on Consumer Safety Opinion On Hydroxyapatite (Nano)
…which is still very safe (you’d need to brush your teeth, and eat all the toothpaste, about 500 times per day, to get to toxic levels, if we run with the same numbers we discussed before. Again, please do not do that, though).
But, since the science so far suggests it’s about twice as toxic as fluoride, then regardless of that still being very safe, the fluoride is obviously (by the same metric) twice as safe, hence picking the fluoride.

Is still water better for you than sparkling water?
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.
Still or sparkling? It’s a question you’ll commonly hear in a café or restaurant and you probably have a preference. But is there any difference for your health?
If you love the fizz, here’s why you don’t have to pass on the sparkling water.
Brent Hofacker/Shutterstock What makes my water sparkle?
This article specifically focuses on comparing still filtered water to carbonated filtered water (called “sparkling water” or “unflavoured seltzer”). Soda water, mineral water, tonic water and flavoured water are similar, but not the same product.
The bubbles in sparkling water are created by adding carbon dioxide to filtered water. It reacts to produce carbonic acid, which makes sparkling water more acidic (a pH of about 3.5) than still (closer to neutral, with a pH around 6.5-8.5).
Which drink is healthiest?
Water is the best way to hydrate our bodies. Research shows when it comes to hydration, still and sparkling water are equally effective.
Some people believe water is healthier when it comes from a sealed bottle. But in Australia, tap water is monitored very carefully. Unlike bottled water, it also has the added benefit of fluoride, which can help protect young children against tooth decay and cavities.
Sparkling or still water is always better than artificially sweetened flavoured drinks or juices.
Isn’t soda water bad for my teeth and bones?
There’s no evidence sparkling water damages your bones. While drinking a lot of soft drinks is linked to increased fractures, this is largely due to their association with higher rates of obesity.
Sparkling water is more acidic than still water, and acidity can soften the teeth’s enamel. Usually this is not something to be too worried about, unless it is mixed with sugar or citrus, which has much higher levels of acidity and can harm teeth.
However, if you grind your teeth often, the softening could enhance the damage it causes. If you’re undertaking a home whitening process, sparkling water might discolour your teeth.
In most other cases, it would take a lot of sparkling water to pass by the teeth, for a long period of time, to cause any noticeable damage.
How does drinking water affect digestion?
There is a misconception drinking water (of any kind) with a meal is bad for digestion.
While theoretically water could dilute stomach acid (which breaks down food), the practice of drinking it doesn’t appear to have any negative effect. Your digestive system simply adapts to the consistency of the meal.
Some people do find that carbonated beverages cause some stomach upset. This is due to the build-up of gases, which can cause bloating, cramping and discomfort. For people with an overactive bladder, the acidity might also aggravate the urinary system.
Interestingly, the fizzy “buzz” you feel in your mouth from sparkling water fades the more you drink it.
Is cold water harder to digest?
You’ve chosen still or sparkling water. What about its temperature?
There are surprisingly few studies about the effect of drinking cold water compared to room temperature. There is some evidence colder water (at two degrees Celsius) might inhibit gastric contractions and slow down digestion. Ice water may constrict blood vessels and cause cramping.
However other research suggests drinking cold water might temporarily boost metabolism, as the body needs to expend energy to warm it up to body temperature. This effect is minimal and unlikely to lead to significant weight loss.
Which water wins?
The bottom line is water is essential, hydrates us and has countless other health benefits. Water, with carbonated bubbles or without, will always be the healthiest drink to choose.
And if you’re concerned about any impact to teeth enamel, one trick is to follow sparkling water with a glass of still. This helps rinse the teeth and return your mouth’s acidity back to normal.

The Fascinating Truth About Aspartame, Cancer, & Neurotoxicity
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.
Is Aspartame’s Reputation Well-Deserved?
In Tuesday’s newsletter, we asked you for your health-related opinions on aspartame, and got the above-depicted, below-described, set of responses:
- About 47% said “It is an evil carcinogenic neurotoxin”
- 20% said “It is safe-ish, but has health risks that are worse than sugar”
- About 19% said “It is not healthy, but better than sugar”
- About 15% said “It’s a perfectly healthy replacement for sugar”
But what does the science say?
Aspartame is carcinogenic: True or False?
False, assuming consuming it in moderation. In excess, almost anything can cause cancer (oxygen is a fine example). But for all meaningful purposes, aspartame does not appear to be carcinogenic. For example,
❝The results of these studies showed no evidence that these sweeteners cause cancer or other harms in people.❞
~ NIH | National Cancer Institute
Source: Artificial Sweeteners and Cancer
Plenty of studies and reviews have also confirmed this; here are some examples:
- Evaluation of aspartame cancer epidemiology studies based on quality appraisal criteria
- Aspartame, low-calorie sweeteners and disease: Regulatory safety and epidemiological issues
- Aspartame: A review of genotoxicity data
Why then do so many people believe it causes cancer, despite all the evidence against it?
Well, there was a small study involving giving megadoses to rats, which did increase their cancer risk. So of course, the popular press took that and ran with it.
But those results have not been achieved outside of rats, and human studies great and small have all been overwhelmingly conclusive that moderate consumption of aspartame has no effect on cancer risk.
Aspartame is a neurotoxin: True or False?
False, again assuming moderate consumption. If you’re a rat being injected with a megadose, your experience may vary. But a human enjoying a diet soda, the aspartame isn’t the part that’s doing you harm, so far as we know.
For example, the European Food Safety Agency’s scientific review panel concluded:
❝there is still no substantive evidence that aspartame can induce such effects❞
~ Dr. Atkin et al (it was a pan-European team of 21 experts in the field)
Source: Report on the Meeting on Aspartame with National Experts
See also,
❝The data from the extensive investigations into the possibility of neurotoxic effects of aspartame, in general, do not support the hypothesis that aspartame in the human diet will affect nervous system function, learning or behavior.
The weight of existing evidence is that aspartame is safe at current levels of consumption as a nonnutritive sweetener.❞
and
❝The safety testing of aspartame has gone well beyond that required to evaluate the safety of a food additive.
When all the research on aspartame, including evaluations in both the premarketing and postmarketing periods, is examined as a whole, it is clear that aspartame is safe, and there are no unresolved questions regarding its safety under conditions of intended use.❞
Source: Regulatory Toxicology & Pharmacology | Aspartame: Review of Safety
Why then do many people believe it is a neurotoxin? This one can be traced back to a chain letter hoax from about 26 years ago; you can read it here, but please be aware it is an entirely debunked hoax:

7 Kinds Of Rest When Sleep Is Not Enough
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.
Taking Rest Seriously (More Than Just Sleep)
This is Dr. Matthew Edlund. He has 44 years experience as a psychiatrist, and is also a sleep specialist. He has a holistic view of health, which is reflected in his practice; he advocates for “a more complete health: physical, mental, social, and spiritual well-being”.
What does he want us to know?
Sleep, yes
Sleep cannot do all things for us in terms of rest, but it can do a lot, and it is critical. It is, in short, a necessary-but-not-sufficient condition for being well-rested.
See also: Why You Probably Need More Sleep
Rest actively
Rest is generally thought of as a passive activity, if you’ll pardon the oxymoron. Popular thinking is that it’s not something defined by what we do, so much what we stop doing.
In contrast, Dr. Edlund argues that to take rest seriously, we need do restful things.
Rest is as important as eating, and we wouldn’t want for that to “just happen”, would we?
Dr. Edlund advocates for restful activities such as going to the garden (or a nearby park) to relax. He also suggests we not underestimate the power of sex as an actively restful activity—this one is generally safer in the privacy of one’s home, though!
Rest physically
This is about actively relaxing our body—yoga is a great option here, practised in a way that is not physically taxing, but is physically rejuvenating; gentle stretches are key. Without such things, our body will keep tension, and that is not restful.
For the absolute most restful yogic practice? Check out:
Non-Sleep Deep Rest: A Neurobiologist’s Take
this is about yoga nidra!
Rest mentally
The flipside of the above is that we do need to rest our mind also. When we try to rest from a mental activity by taking on a different mental activity that uses the same faculties of the brain, it is not restful.
Writer’s example: as a writer, I could not rest from my writing by writing recreationally, or even by reading. An accountant, however, could absolutely rest from accounting by picking up a good book, should they feel so inclined.
Rest socially
While we all have our preferences when it comes to how much or how little social interaction we like in our lives, humans are fundamentally social creatures, and it is hardwired into us by evolution to function at our best in a community.
This doesn’t mean you have to go out partying every night, but it does mean you should take care to spend at least a little time with friends, even if just once or twice per week, and yes, even if it’s just a videocall (in person is best, but not everyone lives close by!)
If your social life is feeling a little thin on the ground these days, that’s a very common thing—not only as we get older, but also as many social institutions took a dive in functionality on account of the pandemic, and many are still floundering. Nevertheless, there are more options than you probably realize; yes, even for the naturally reclusive:
How To Beat Loneliness & Isolation
Rest spiritually
Be we religious or not, there are scientifically well-evidenced benefits to religious practices—some are because of the social aspect, and follow on from what we talked about just above. Other benefits come from activities such as prayer or meditation (which means that having some kind of faith, while beneficial, is not actually a requirement for spiritual rest—comparable practices without faith are fine too).
We discussed the overlapping practices of prayer and meditation, here:
The Science Of Mantra Meditation
Rest at home
Obviously, most people sleep at home. But…
Busy family homes can sometimes need a bit of conscious effort to create a restful environment, even if just for a while. A family dinner together is one great way to achieve this, and also ties in with the social element we mentioned before!
A different challenge faced by a lot of older people without live-in families, on the other hand, is the feeling of too much opportunity for rest—and then a feeling of shame for taking it. The view is commonly held that, for example, taking an afternoon nap is a sign of weakness.
On the contrary: taking an afternoon nap can be a good source of strength! Check out:
How To Nap Like A Pro (No More “Sleep Hangovers”!)
Rest at work
Our readership has a lot of retirees, but we know that’s not the case for everyone. How then, to rest while at work? Ideally we have breaks, of course, but most workplaces do not exactly have an amusement arcade in the break room. Nevertheless, there are some quick resets that can be done easily, anywhere, and (almost) any time:

The Humor Habit – by Paul Osincup
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.
Ask not for whom the bell tolls… It could be tolling for anyone. Don’t worry about it.It’s probably fine.
More seriously (heh), laughter is good for healthy lifespan, also called healthspan. It eases stress and anxiety, gives our brains neurochemicals they need to function well, and is very pro-social too, which in turn has knock-on positive effects for our own mental health as well as those around us.
This book is a guide to cultivating that humor, finding the funny side in difficult times, and bringing a light-hearted silliness to moments where it helps.
The title suggests it’s about habit-building (and it is!) but it’s also about knowing where to look in your daily life for humorous potential and how to find it, and how to bring that into being in the moment.
The style is that of an instruction manual with a healthy dose of pop-science; first and foremost this is a practical guide, not a several-hundred page exhortation on “find things funny!”, but rather a “hey, psst, here are many sneaky insider tricks for finding the funny“.
Bottom line: this book is not only a very enjoyable read, but also very much the gift that keeps on giving, so treat yourself!

Eggs: Nutritional Powerhouse or Heart-Health Timebomb?
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.
Eggs: All Things In Moderation?
We asked you for your (health-related) opinion on eggs. We specified that, for the sake of simplicity, let’s say that they are from happy healthy backyard hens who enjoy a good diet.
Apparently this one wasn’t as controversial as it might have been! We (for myth-busting purposes) try to pick something polarizing and sometimes even contentious for our Friday editions, and pick apart what science lies underneath public perceptions.
However, more than half (in fact, 60%) of the subscribers who voted in the poll voted for “Eggs are nutritionally beneficial as part of a balanced diet”, which very moderate statement is indeed pretty much the global scientific consensus.
Still, we’ve a main feature to write, so let’s look at the science, and what the other 40% had in mind:
Eggs are ruinous to health, especially cardiometabolic health: True or False?
False, per best current science, anyway!
Scientific consensus has changed over the years. We learned about cholesterol, then we learned about different types of cholesterol, and now we’ve even learned about in some instances even elevated levels of “bad” cholesterol aren’t necessarily a cause of cardiometabolic disorders so much as a symptom—especially in women.
Not to derail this main feature about eggs (rather than just cholesterol), but for those who missed it, this is actually really interesting: basically, research (pertaining to the use of statins) has found that in women, higher LDL levels aren’t anywhere near the same kind of risk factor as they are for men, and thus may mean that statins (whose main job is reducing LDL) may be much less helpful for women than for men, and more likely to cause unwanted serious side effects in women.
Check out our previous main feature about this: Statins: His & Hers?
But, for back on topic, several large studies (totalling 177,000 people in long-term studies in 50 countries) found:
❝Results from the three cohorts and from the updated meta-analysis show that moderate egg consumption (up to one egg per day) is not associated with cardiovascular disease risk overall, and is associated with potentially lower cardiovascular disease risk in Asian populations.❞
Egg whites are healthy (protein); egg yolks are not (cholesterol): True or False?
True and False, respectively. That is to say, egg whites are healthy (protein), and egg yolks are also healthy (many nutrients).
We talked a bit already about cholesterol, so we’ll not rehash that here. As to the rest:
Eggs are one of the most nutritionally dense foods around. After all, they have everything required to allow a cluster of cells to become a whole baby chick. That’s a lot of body-building!
They’re even more nutritionally heavy-hitters if you get omega-3 enriched eggs, which means the hens were fed extra omega-3, usually in the form of flax seeds.
Also, free-range is better healthwise than others. Do bear in mind that unless they really are from your backyard, or a neighbor’s, chances are that the reality is not what the advertising depicts, though. There are industry minimum standards to be able to advertise as “free-range”, and those standards are a) quite low b) often ignored, because an occasional fine is cheaper than maintaining good conditions.
So if you can look after your own hens, or get them from somewhere that you can see for yourself how they are looked after, so much the better!
Check out the differences side-by-side, though:
Pastured vs Omega-3 vs “Conventional” Eggs: What’s the Difference?
Stallone-style 12-egg smoothies are healthy: True or False?
False, at least if taken with any regularity. One can indeed have too much of a good thing.
So, what’s the “right amount” to eat?
It may vary depending on individual factors (including age and ethnicity), but a good average, according to science, is to keep it to 3 eggs or fewer per day. There are a lot of studies, but we only have so much room here, so we’ll pick one. Its findings are representative of (and in keeping with) the many other studies we looked at, so this seems uncontroversial scientifically:
❝Intake of 1 egg/d was sufficient to increase HDL function and large-LDL particle concentration; however, intake of 2-3 eggs/d supported greater improvements in HDL function as well as increased plasma carotenoids. Overall, intake of ≤3 eggs/d favored a less atherogenic LDL particle profile, improved HDL function, and increased plasma antioxidants in young, healthy adults.❞
