Chickpeas vs Mung Beans – 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 chickpeas to mung beans, we picked the chickpeas.
Why?
Both are great! But there’s a clear winner here:
In terms of macros, chickpeas have more protein, carbs, and fiber, as well as the lower glycemic index. The difference is very small, but it’s a nominal win for chickpeas.
When it comes to vitamins, chickpeas have more of vitamins A, B2, B6, B9, C, E, K, and choline, while mung beans have more of vitamins B1, B3, and B5. Again the differences aren’t huge, but by strength of numbers they’re in chickpeas’ favor, so it’s another win for chickpeas here.
In the category of minerals, chickpeas have more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while mung beans are not higher in any mineral. An easy win for chickpeas on this one.
Adding up the sections makes for a clear overall win for chickpeas, but by all means enjoy either or both; diversity is good!

Cherries vs Blueberries – 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 cherries to blueberries, we picked the blueberries.
Why?
It was close! And blueberries only won by virtue of taking an average value for cherries; we could have (if you’ll pardon the phrase) cherry-picked tart cherries for extra benefits that’d put them ahead of blueberries. That’s how close it is.
In terms of macros, they are almost identical, so nothing to set them apart there.
In the category of vitamins, they are mostly comparable except that blueberries have a lot more vitamin K, and cherries have a lot more vitamin A. Since vitamin K is the vitamin that’s scarcer in general, we’ll call blueberries’ vitamin K content a win.
Blueberries do also have about 6x more vitamin E, with a cup of blueberries containing about 10% of the daily requirement (and cherries containing almost none). Another small win for blueberries.
When it comes to minerals, they are mostly comparable; the largest point of difference is that blueberries contain more manganese while cherries contain more copper; nothing to decide between them here.
We’re down to counting amino acids and antioxidants now, so blueberries have a lot more cystine and tyrosine. They also have slightly more of amino acids that they both only have trace amounts of. And as for antioxidants? Blueberries contain notably more quercetin.
So, blueberries win the day—but if we had specified tart cherries rather than taking an average, they could have come out on top. Enjoy both!

Could Just Two Hours Sleep Per Day Be 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.
Polyphasic Sleep… Super-Schedule Or An Idea Best Put To Rest?
What is it?
Let’s start by defining some terms:
- Monophasic sleep—sleeping in one “chunk” per day. For example, a good night’s “normal” sleep.
- Biphasic sleep—sleeping in two “chunks” per day. Typically, a shorter night’s sleep, with a nap usually around the middle of the day / early afternoon.
- Polyphasic sleep—sleeping in two or more “chunks per day”. Some people do this in order to have more hours awake per day, to do things. The idea is that sleeping this way is more efficient, and one can get enough rest in less time. The most popular schedules used are:
- The Überman schedule—six evenly-spaced 20-minute naps, one every four hours, throughout the 24-hour day. The name is a semi-anglicized version of the German word Übermensch, “Superman”.
- The Everyman schedule—a less extreme schedule, that has a three-hours “long sleep” during the night, and three evenly-spaced 20-minute naps during the day, for a total of 4 hours sleep.
There are other schedules, but we’ll focus on the most popular ones here.
Want to learn about the others? Visit: Polyphasic.Net (a website by and for polyphasic sleep enthusiasts)
Some people have pointed to evidence that suggests humans are naturally polyphasic sleepers, and that it is only modern lifestyles that have forced us to be (mostly) monophasic.
There is at least some evidence to suggest that when environmental light/dark conditions are changed (because of extreme seasonal variation at the poles, or, as in this case, because of artificial changes as part of a sleep science experiment), we adjust our sleeping patterns accordingly.
The counterpoint, of course, is that perhaps when at the mercy of long days/nights at the poles, or no air-conditioning to deal with the heat of the day in the tropics, that perhaps we were forced to be polyphasic, and now, with modern technology and greater control, we are free to be monophasic.
Either way, there are plenty of people who take up the practice of polyphasic sleep.
Ok, But… Why?
The main motivation for trying polyphasic sleep is simply to have more hours in the day! It’s exciting, the prospect of having 22 hours per day to be so productive and still have time over for leisure.
A secondary motivation for trying polyphasic sleep is that when the brain is sleep-deprived, it will prioritize REM sleep. Here’s where the Überman schedule becomes perhaps most interesting:
The six evenly-spaced naps of the Überman schedule are each 20 minutes long. This corresponds to the approximate length of a normal REM cycle.
Consequently, when your head hits the pillow, you’ll immediately begin dreaming, and at the end of your dream, the alarm will go off.
Waking up at the end of a dream, when one hasn’t yet entered a non-REM phase of sleep, will make you more likely to remember it. Similarly, going straight into REM sleep will make you more likely to be aware of it, thus, lucid dreaming.
Read: Sleep fragmentation and lucid dreaming (actually a very interesting and informative lucid dreaming study even if you don’t want to take up polyphasic sleep)
Six 20-minute lucid-dreaming sessions per day?! While awake for the other 22 hours?! That’s… 24 hours per day of wakefulness to use as you please! What sorcery is this?
Hence, it has quite an understandable appeal.
Next Question: Does it work?
Can we get by without the other (non-REM) kinds of sleep?
According to Überman cycle enthusiasts: Yes! The body and brain will adapt.
According to sleep scientists: No! The non-REM slow-wave phases of sleep are essential
Read: Adverse impact of polyphasic sleep patterns in humans—Report of the National Sleep Foundation sleep timing and variability consensus panel
(if you want to know just how bad it is… the top-listed “similar article” is entitled “Suicidal Ideation”)
But what about, for example, the Everman schedule? Three hours at night is enough for some non-REM sleep, right?
It is, and so it’s not as quickly deleterious to the health as the Überman schedule. But, unless you are blessed with rare genes that allow you to operate comfortably on 4 hours per day (you’ll know already if that describes you, without having to run any experiment), it’s still bad.
Adults typically need 7–9 hours of sleep per night, and if you don’t get it, you’ll accumulate a sleep debt. And, importantly:
When you accumulate sleep debt, you are borrowing time at a very high rate of interest!
And, at risk of laboring the metaphor, but this is important too:
Not only will you have to pay it back soon (with interest), you will be hounded by the debt collection agents—decreased cognitive ability and decreased physical ability—until you pay up.
In summary:
- Polyphasic sleep is really very tempting
- It will give you more hours per day (for a while)
- It will give the promised lucid dreaming benefits (which is great until you start micronapping between naps, this is effectively a mini psychotic break from reality lasting split seconds each—can be deadly if behind the wheel of a car, for instance!)
- It is unequivocally bad for the health and we do not recommend it
Bottom line:
Some of the claimed benefits are real, but are incredibly short-term, unsustainable, and come at a cost that’s far too high. We get why it’s tempting, but ultimately, it’s self-sabotage.
(Sadly! We really wanted it to work, too…)

We Are Such Stuff As Fish Are Made Of

Research Review: Collagen
For something that’s a very popular supplement, not many people understand what collagen is, where it comes from, or what it does.
In a nutshell:
Collagen is a kind of protein. Our bodies make it naturally, and we can also get more in our diet and/or take extra as a supplement.
Our bodies use collagen in connective tissue, skin, tendon, bone, and cartilage. It has many functions, but a broad description would be “holding things together”.
As we get older, our bodies produce less collagen. Signs of this include wrinkles, loss of skin hydration, and joint pain.
Quick test: pinch the skin on the middle of the back of one of your hands, and then watch what happens when you get low. How quickly and easily did your skin returns to its original shape?
If it was pretty much instantanous and flawless, congratulations, you have plenty of collagen (and also elastin). If you didn’t, you are probably low on both!
(they are quite similar proteins and are made from the same base “stuff”, so if you’re low on one, you’ll usually be low on both)
Quick note: A lot of research out there has been funded by beauty companies, so we had our work cut out for us today, and have highlighted where any research may be biased.
More than skin deep
While marketing for collagen is almost exclusively aimed at “reduce wrinkles and other signs of aging”, it does a lot more than that.
You remember we mentioned that many things from the bones outward are held together by collagen? We weren’t kidding…
Read: Osteoporosis, like skin ageing, is caused by collagen loss which is reversible
Taking extra collagen isn’t the only way
We can’t (yet!) completely halt the age-related loss of collagen, but we can slow it, with our lifestyle choices:
- Don’t smoke tobacco
- Drink only in moderation (or not at all)
- Avoid foods with added sugar, and high-processed foods in general
- Wear sunscreen when appropriate
Can I get collagen from food?
Yep! Just as collagen holds our bodies together, it holds the bodies of other animals together. And, just like collagen is found in most parts of our body but most plentifully in our skin and bones, that’s what to eat to get collagen from other animals, e.g:
- Chicken skin
- Fish skin
- Bone broth ← health benefits and recipes at this link!
What about vegans?
Yes, vegans are also held together by collagen! We do not, however, recommend eating their skin or boiling their bones into broth. Ethical considerations aside, cannibalism can give you CJD!
More seriously, if you’re vegan, you can’t get collagen from a plant-based diet, but you can get the stuff your body uses to make collagen. Basically, you want to make sure you get plenty of:
- Protein (beans, pulses, nuts, etc are all fine; it’s hard to go wrong with this)
- Vitamin C
- Vitamin D
- and Zinc
Just be sure to continue to remember to avoid highly-processed foods. So:
- Soy mince/chunks whose ingredients list reads: “soya”? Yes!
- The Incredible Burger or Linda McCartney’s Sausages? Sadly less healthy
Read: Advanced Glycation End Products in Foods and a Practical Guide to Their Reduction in the Diet
Meat-eaters might want to read that one too. By far the worst offenders for AGEs (Advanced Glycation End Products, which can not only cause collagen to stiffen, but also inactivate proteins responsible for collagen repair, along with doing much more serious damage to your body’s natural functions) include:
- Hot dogs
- Bacon
- Fried/roasted/grilled meats
Is it worth it as a supplement?
That depends on you, your age, and your lifestyle, but it’s generally considered safe*
*if you have a seafood allergy, be careful though, as many supplements are from fish or shellfish—you will need to find one that’s free from your allergen
Also, all collagen is animal-derived. So if you’re a vegan, decide for yourself whether this constitutes medicine and if so, whether that makes it ethically permissible to you.
With that out of the way:
What the science says on collagen supplementation
Collagen for skin
Read: Effects of collagen supplementation on skin aging (systematic review and meta-analysis)
The short version is that they selected 19 studies with over a thousand participants in total, and they found:
In the meta-analysis, a grouped analysis of studies showed favorable results of hydrolyzed collagen supplementation compared with placebo in terms of skin hydration, elasticity, and wrinkles.
The findings of improved hydration and elasticity were also confirmed in the subgroup meta-analysis.
Based on results, ingestion of hydrolyzed collagen for 90 days is effective in reducing skin aging, as it reduces wrinkles and improves skin elasticity and hydration.
Caveat: while that systematic review had no conflicts of interests, at least some of the 19 studies will have been funded by beauty companies. Here are two, so that you know what that looks like:
Funded by Quiris to investigate their own supplement, Elasten®:
A Collagen Supplement Improves Skin Hydration, Elasticity, Roughness, and Density
Funded by BioCell to investigate their own supplement, BioCell Collagen:
The Effects of Skin Aging Associated with the Use of BioCell Collagen
A note on funding bias: to be clear, the issue is not that the researchers might be corrupt (though that could happen).
The issue is more that sometimes companies will hire ten labs to do ten research studies… and then pull funding from ones whose results aren’t going the way they’d like.
So the “best” (for them) study is the one that gets published.
Here’s another systematic review—like the one at the top of this section—that found the same, with doses ranging from 2.5g–15g per day for 8 weeks or longer:
Read: Oral Collagen Supplementation: A Systematic Review of Dermatological Applications
Again, some of those studies will have been funded by beauty companies. The general weight of evidence does seem clear and favorable, though.
Collagen for bones
Here, we encountered a lot less in the way of potential bias, because this is simply marketed a lot less. Despite being arguably far more important!
We found a high quality multi-vector randomized controlled study with a sample size of 131 postmenopausal women. They had these women take 5g collagen supplement (or placebo), and studied the results over the course of a year.
They found:
- The intake of the supplement increased bone mineral density (BMD)
- Supplementation was also associated with a favorable shift in bone markers, indicating:
- increased bone formation
- reduced bone degradation
Read: Specific Collagen Peptides Improve Bone Mineral Density and Bone Markers in Postmenopausal Wome
A follow-up study with 31 of these women found that taking 5 grams of collagen daily for a total of 4 years was associated with a progressive increase in BMD.
You might be wondering if collagen also helps against osteoarthritis.
The answer is: yes, it does (at least, it significantly reduces the symptoms)
Read: Effect of collagen supplementation on osteoarthritis symptoms
In summary:
- You need collagen for health skin, bones, joints, and more
- Your body makes collagen from your food
- You can help it by getting plenty of protein, vitamins, and minerals
- You can also help it by not doing the usual Bad Things™ (smoking, drinking, eating processed foods, especially processed meats)
- You can also eat collagen directly in the form of other animals’ skin and bones
- You can also buy collagen supplements (but watch out for allergens)
Want to try collagen supplementation?
We don’t sell it (or anything else), but for your convenience…
Check it out: Hydrolyzed Collagen Peptides (the same as in most of the above studies), 90 days supply at 5g/day
We selected this one because it’s the same kind used in many of the studies, and it doesn’t contain any known allergens.
It’s bovine collagen, meaning it’s from cows, so it’s not vegan, and also some subscribers may want to abstain for religious reasons. We respect that, and/but make our recommendations based solely on the science of health and productivity.

The Polyvagal Theory – by Dr. Stephen Porges
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.
Do you ever find that your feelings (or occasionally: lack thereof) sometimes can seem mismatched with the observed facts of your situation? This book unravels that mystery—or rather, that stack of mysteries.
Dr. Porges’ work on this topic is, by the way, the culmination of 40 years of research. While he’s not exactly a household name to the layperson, he’s very respected in his field, and this book is his magnum opus.
Here he explains the disparate roles of the two branches of the vagus nerve (hence: polyvagal theory). At least, the two branches that we mammals have; non-mammalian vertebrates have only one. This makes a big difference, because of the cascade of inhibitions that this allows.
The answer to the very general question “What stops you from…?” is usually found somewhere down this line of cascade of inhibitions.
These range from “what stops you from quitting your job/relationship/etc” to “what stops you from freaking out” to “what stops you from relaxing” to “what stops you from reacting quickly” to “what stop you from giving up” to “what stops you from gnawing your arm off” and many many more.
And because sometimes we wish we could do something that we can’t, or wish we wouldn’t do something that we do, understanding this process can be something of a cheat code to life.
A quick note on style: the book is quite dense and can be quite technical, but should be comprehensible to any layperson who is content to take their time, because everything is explained as we go along.
Bottom line: if you’d like to better understand the mysteries of how you feel vs how you actually are, and what that means for what you can or cannot wilfully do, this is a top-tier book

Anchovies vs Sardines – 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 anchovies to sardines, we picked the sardines.
Why?
In terms of macros, sardines have slightly more protein and more than 2x the fat, but the fat profile is healthier than that of anchovies, meaning that the amount of saturated fat is the same, and sardines have more poly- and monounsaturated fats. Breaking it down further, sardines also have more omega-3. Unless you are for whatever reason especially keen to keep your total fat* intake down, sardines win here.
*or calories, which in this case come almost entirely from the fat, and sardines are consequently nearly 2x higher in calories.
When it comes to vitamins, sardines further distinguish themselves; anchovies have more of vitamins B2 and B3, while sardines have more of vitamins A, B1, B6, B12, B9, E, and K—in some cases, by quite large margins (especially the B12 and K, being 14x more and 26x more, respectively). A clear win for sardines.
Minerals are closer to even; anchovies have more copper, iron, and zinc, while sardines have more calcium, manganese, phosphorus, and selenium. That’s already a slight win for sardines, before we take into account that sardines’ margins of difference are also much greater than anchovies’.
In short, enjoy either in moderation if you are so inclined, but sardines win on overall nutritional density.

When Age Is A Flexible Number
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.
Aging, Counterclockwise!
In the late 1970s, Dr. Ellen Langer hypothesized that physical markers of aging could be affected by psychosomatic means.
Note: psychosomatic does not mean “it’s all in your head”.
Psychosomatic means “your body does what your brain tells it to do, for better or for worse”
She set about testing that, in what has been referred to since as…
The Counterclockwise Study
A small (n=16) sample of men in their late 70s and early 80s were recruited in what they were told was a study about reminiscing.
Back in the 1970s, it was still standard practice in the field of psychology to outright lie to participants (who in those days were called “subjects”), so this slight obfuscation was a much smaller ethical aberration than in some famous studies of the same era and earlier (cough cough Zimbardo cough Milgram cough).
Anyway, the participants were treated to a week in a 1950s-themed retreat, specifically 1959, a date twenty years prior to the experiment’s date in 1979. The environment was decorated and furnished authentically to the date, down to the food and the available magazines and TV/radio shows; period-typical clothing was also provided, and so forth.
- The control group were told to spend the time reminiscing about 1959
- The experimental group were told to pretend (and maintain the pretense, for the duration) that it really was 1959
The results? On many measures of aging, the experimental group participants became quantifiably younger:
❝The experimental group showed greater improvement in joint flexibility, finger length (their arthritis diminished and they were able to straighten their fingers more), and manual dexterity.
On intelligence tests, 63 percent of the experimental group improved their scores, compared with only 44 percent of the control group. There were also improvements in height, weight, gait, and posture.
Finally, we asked people unaware of the study’s purpose to compare photos taken of the participants at the end of the week with those submitted at the beginning of the study. These objective observers judged that all of the experimental participants looked noticeably younger at the end of the study.❞
Remember, this was after one week.
Her famous study was completed in 1979, and/but not published until eleven years later in 1990, with the innocuous title:
Higher stages of human development: Perspectives on adult growth
You can read about it much more accessibly, and in much more detail, in her book:
Counterclockwise: A Proven Way to Think Yourself Younger and Healthier – by Dr. Ellen Langer
We haven’t reviewed that particular book yet, so here’s Linda Graham’s review, that noted:
❝Langer cites other research that has made similar findings.
In one study, for instance, 650 people were surveyed about their attitudes on aging. Twenty years later, those with a positive attitude with regard to aging had lived seven years longer on average than those with a negative attitude to aging.
(By comparison, researchers estimate that we extend our lives by four years if we lower our blood pressure and reduce our cholesterol.)
In another study, participants read a list of negative words about aging; within 15 minutes, they were walking more slowly than they had before.❞
Read the review in full:
Aging in Reverse: A Review of Counterclockwise
The Counterclockwise study has been repeated since, and/but we are still waiting for the latest (exciting, much larger sample, 90 participants this time) study to be published. The research proposal describes the method in great detail, and you can read that with one click over on PubMed:
It was approved, and has now been completed (as of 2020), but the results have not been published yet; you can see the timeline of how that’s progressing over on ClinicalTrials.gov:
Clinical Trials | Ageing as a Mindset: A Counterclockwise Experiment to Rejuvenate Older Adults
Hopefully it’ll take less time than the eleven years it took for the original study, but in the meantime, there seems to be nothing to lose in doing a little “Citizen Science” for ourselves.
Maybe a week in a 20 years-ago themed resort (writer’s note: wow, that would only be 2004; that doesn’t feel right; it should surely be at least the 90s!) isn’t a viable option for you, but we’re willing to bet it’s possible to “microdose” on this method. Given that the original study lasted only a week, even just a themed date-night on a regular recurring basis seems like a great option to explore (if you’re not partnered then well, indulge yourself how best you see fit, in accord with the same premise; a date-night can be with yourself too!).
Just remember the most important take-away though:
Don’t accidentally put yourself in your own control group!
In other words, it’s critically important that for the duration of the exercise, you act and even think as though it is the appropriate date.
If you instead spend your time thinking “wow, I miss the [decade that does it for you]”, you will dodge the benefits, and potentially even make yourself feel (and thus, potentially, if the inverse hypothesis holds true, become) older.
This latter is not just our hypothesis by the way, there is an established potential for nocebo effect.
For example, the following study looked at how instructions given in clinical tests can be worded in a way that make people feel differently about their age, and impact the results of the mental and/or physical tests then administered:
❝Our results seem to suggest how manipulations by instructions appeared to be more largely used and capable of producing more clear performance variations on cognitive, memory, and physical tasks.
Age-related stereotypes showed potentially stronger effects when they are negative, implicit, and temporally closer to the test of performance. ❞
(and yes, that’s the same Dr. Francesco Pagnini whose name you saw atop the other study we cited above, with the 90 participants recreating the Counterclockwise study)
