What Your Hands Can Tell You About Your Health

Dr. Siobhan Deshauer tells us what our hands say about our health—she’s not practicing palmistry though; she’s a rheumatologist, and everything here is about clinical signs of health/disease.
The signs include…
“Spider fingers” (which your writer here has; I always look like I’m ready to cast a spell of some kind), and that’s really the medical name, or arachnodactyly for those who like to get Greek about it. It’s about elongated digits. Elongated other bones too, typically, but the hands are where it’s most noticeable.
The tests:
- Make a fist with your thumb inside (the way you were told never to punch); does your thumb poke out the side notably past the edge of your hand, unassisted (i.e., don’t poke it, just let it rest where it goes to naturally)?
- Take hold of one of your wrists with the fingers of the other hand, wrapping them around. If they reach, that’s normal; if there’s a notable overlap, we’re in Spidey-territory now.
If both of those are positive results for you, Dr. Deshauer recommends getting a genetic test to see if you have Marfan syndrome, because…
Arachnodactyly often comes from a genetic condition called Marfan syndrome, and as well as the elongated digits of arachnodactyly, Marfan syndrome affects the elastic fibers of the body, and comes with the trade-off of an increased risk of assorted kinds of sudden death (if something goes “ping” where it shouldn’t, like the heart or lungs).
But it can also come from Ehlers-Danlos Syndrome!
EDS is characterized by hypermobility of joints, meaning that they are easily flexed past the normal human limit, and/but also easily dislocated.
The tests:
- Put your hand flat on a surface, and using your other hand, see how far back your fingers will bend (without discomfort, please); do they go further than 90°?
- Can you touch your thumb to your wrist* (on the same side?)
*She says “wrist”; for this arachnodactylic writer here it’s halfway down my forearm, but you get the idea
For many people this is a mere quirk and inconvenience, for others it can be more serious and a cause of eventual chronic pain, and for a few, it can be very serious and come with cardiovascular problems (similar to the Marfan syndrome issues above). This latter is usually diagnosed early in life, though, such as when a child comes in with an aneurysm, or there’s a family history of it. Another thing to watch out for!
Check out the video for more information on these, as well as what our fingerprints can mean, indicators of diabetes (specifically, a test for diabetic cheiroarthropathy that you can do at home, like the tests above), carpal tunnel syndrome, Raynaud phenomenon, and more!

To Pee Or Not To Pee
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 it “strengthening” to hold, or are we doing ourselves harm if we do? Dr. Heba Shaheed explains in this short video:
A flood of reasons not to hold
Humans should urinate 4–6 times daily, but for many people, the demands of modern life often lead to delaying urination, raising questions about its effects on the body.
So first, let’s look at how it all works: the bladder is part of the urinary system, which includes the kidneys, ureters, urethra, and sphincters. Urine is produced by the kidneys and transported via the ureters into the bladder, a hollow organ with a muscular wall. This muscle (called the detrusor) allows the bladder to inflate as it fills with urine (bearing in mind, the main job of any muscle is to be able to stretch and contract).
As the bladder fills, stretch receptors in that muscle signal fullness to the spinal cord. This triggers the micturition reflex, causing the detrusor to contract and the internal urethral sphincter to open involuntarily. Voluntary control over the external urethral sphincter allows a person to delay or release urine as needed.
So, at what point is it best to go forth and pee?
For most people, bladder fullness is first noticeable at around 150-200ml, with discomfort occurring at 400-500ml (that’s about two cups*). Although the bladder can stretch to hold up to a liter, exceeding this capacity can cause it to rupture, a rare but serious condition requiring surgical intervention.
*note, however, that this doesn’t necessarily mean that drinking two cups will result in two cups being in your bladder; that’s not how hydration works. Unless you are already perfectly hydrated, most if not all of the water will be absorbed into the rest of your body where it is needed. Your bladder gets filled when your body has waste products to dispose of that way, and/or is overhydrated (though overhydration is not very common).
Habitually holding urine and/or urinating too quickly (note: not “too soon”, but literally, “too quickly”, we’re talking about the velocity at which it exits the body) can weaken pelvic floor muscles over time. This can lead to bladder pain, urgency, incontinence, and/or a damaged pelvic floor.
In short: while the body’s systems are equipped to handle occasional delays, holding it regularly is not advisable. For the good of your long-term urinary health, it’s best to avoid straining the system and go whenever you feel the urge.

Eat Move Sleep – by Tom Rath
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 subtitle of this book, “how small choices lead to big changes“, is very much the idea that a lot of what we do here at 10almonds is about.
And the title itself, “Eat Move Sleep”? Well, that’s 3/5 of The Usual Five Things™ that we promote here (the other two being: reduce or eliminate alcohol, and don’t smoke). So, naturally this book got our attention.
One of the key ideas that Rath presents is that every action we take leads to a net gain or loss in health. The question then is: what are the biggest point-swingers? In other words, what are the places in our life where the smallest changes can make the biggest difference?
Rath looks at what parts of diet make the biggest difference to our health, and the findings there alone probably make reading the book worthwhile.
When it comes to movement, he actually flips this! For Rath, it’s less about how much exercise you get, and more about minimizing how long we spend not moving… And especially, minimizing how long we spend sitting. So, lots of little tweaks for that.
In the category of sleep: a key idea is that quality is as important as quantity, and there’s an aspect of bringing together as a synergistic routine. To finish off a productive day with good rest, and power up ready for the next morning.
In short: tying these items together—and focusing on the smallest choices that lead to the biggest changes—makes for quite a manifesto that we could describe as “Atomic Habits, for health specifically”.

More Things Dopamine Does For Us
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.
In this week’s news roundup, we have two dopamine items and one other for variety:
The real “dopamine switch”
Dopamine is well-known as “the reward chemical”, and indeed it is that, but it also plays a central role in many neurological processes, including:
- Linear task processing
- Motivation
- Learning and memory
- Motor functions
- Language faculties
Recent research has now shown its importance in cognitive flexibility, i.e. the ability to adapt to circumstances, and switch approaches appropriately to such, and generally not get stuck in a cognitive rut:

It’s been known for a while that dopamine is involved in learning and memory (as mentioned above), but this has been established largely by associative studies, e.g. “people with lower dopamine levels learn less easily”. But scientists have now mapped out more of how it actually does that.
One more reason to ensure we have and maintain healthy dopamine levels!

Resist Or Run!
When it comes to protecting against bone loss, resistance exercise remains key, but impact-laden activities such as running (but not lower-level everyday activity) can help too. There have been studies on the extent to which walking (a load-bearing activity) may be protective against bone loss, and the results of those studies have mostly been inconclusive.
This study looked into the incidence (or not, as the case may be) of bone-loading impacts in everyday movements, using accelerometers, and measured bone mineral density before and after testing periods. Those that had higher-intensity bone-loading movements (so, resistance training or running, for example) retained the best measures of bone density through menopause into postmenopause:

MSG vs. Salt: Sodium Comparison
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.
It’s Q&A Day at 10almonds!
Q: Is MSG healthier than salt in terms of sodium content or is it the same or worse?
Great question, and for that matter, MSG itself is a great topic for another day. But your actual question, we can readily answer here and now:
- Firstly, by “salt” we’re assuming from context that you mean sodium chloride.
- Both salt and MSG do contain sodium. However…
- MSG contains only about a third of the sodium that salt does, gram-for-gram.
- It’s still wise to be mindful of it, though. Same with sodium in other ingredients!
- Baking soda contains about twice as much sodium, gram for gram, as MSG.
Wondering why this happens?
Salt (sodium chloride, NaCl) is equal parts sodium and chlorine, by atom count, but sodium’s atomic mass is lower than chlorine’s, so 100g of salt contains only 39.34g of sodium.
Baking soda (sodium bicarbonate, NaHCO₃) is one part sodium for one part hydrogen, one part carbon, and three parts oxygen. Taking each of their diverse atomic masses into account, we see that 100g of baking soda contains 27.4g sodium.
MSG (monosodium glutamate, C₅H₈NO₄Na) is only one part sodium for 5 parts carbon, 8 parts hydrogen, 1 part nitrogen, and 4 parts oxygen… And all those other atoms put together weigh a lot (comparatively), so 100g of MSG contains only 12.28g sodium.

Pinto Beans vs Fava 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 pinto beans to fava beans, we picked the pinto beans.
Why?
It wasn’t close!
In terms of macros, pinto beans have more protein and carbs, and much more fiber, resulting in a much lower glycemic index. We mention this, because while often the GI of two similar foods is similar, in this case pinto beans have a GI of 39 (low), while fava beans have a GI of 79 (high). In other words, not at all close, and pinto beans are the clear winner.
When it comes to vitamins, pinto beans have more of vitamins B1, B5, B6, B7, B9, C, E, K, and choline, while fava beans have more of vitamins B2 and B3. Once again, not close, and that’s before we take into account the margins of difference for those vitamins; the margins of difference are much greater on the pinto beans’ side of the scale, for example pinto beans having 47x more vitamin E, while fava beans have only 43% more vitamin B2. So, orders of magnitude less. A clear win for pinto beans in all respects.
In the category of minerals, pinto beans have more calcium, iron, magnesium, manganese, phosphorus, potassium, and selenium, while fava beans have more copper and zinc. This time, the margins of difference were quite moderate across the board, and/but pinto beans win on clear strength of numbers.
All in all, three clear wins for pinto beans add up to one big clear win for pinto beans.
Enjoy!

The Vegan Instant Pot Cookbook – by Nisha Vora
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.
We all know that we should “eat the rainbow” (and that no, Skittles do not count)… So why do we often find ourselves falling into the same familiar habits and well-worn comfort foods?
Nisha Vora, of “Rainbow Plant Life“, is here to make things a lot easier—brightening up our plates is her mission!
In this Instant Pot-authorized, beautifully illustrated cookbook, Vora offers us 90 recipes to do just that. And because it’s an Instant Pot cookbook, they’re all super easy.
What if you don’t have an Instant Pot? Well, don’t tell Instant Pot we said this, but another pressure cooker brand will work too. And if you don’t have any pressure cooker, the recipes are modifiable for regular pots and pans. The recipes also lend themselves well to slow-cooker cooking, for that matter!
Where Vora really excels though is in making mostly-one-pot dishes beautiful and tasty.
The recipes, by the way, are drawn from cuisines from all around the world, and cover:
- summer and winter dishes
- breakfasts, sides, mains, desserts
- the healthy and the decadent (and sometimes both!)
As for the presentation of each recipe, we get at least one full-page photo of the finished dish and sometimes extras of the steps. We get a little intro, the usual information about ingredients etc, and a no-fuss step-by-step method. It’s very easy to use.
If you have allergies or other dietary considerations, this book is pretty mindful of those, making substitutions minimal and easy.
Bottom line: this comprehensive book will seriously brighten up the colors of your cooking!
