❝Interesting, but… Did you know spinach is high in oxylates? Some people are sensitive and can cause increased inflammation, joint pain or even kidney stones. Moderation is key. My sister and I like to eat healthy but found out by experience that too much spinach salad caused us joint and other aches.❞

It’s certainly good to be mindful of such things! For most people, a daily serving of spinach shouldn’t cause ill effects, and certainly there are other greens to eat.

We wondered whether there was a way to reduce the oxalate content, and we found:

How to Reduce Oxalic Acid in Spinach: Neutralizing Oxalates

…which led us this product on Amazon:

Nephure Oxalate Reducing Enzyme, Low Oxalate Diet Support

We wondered what “nephure” was, and whether it could be trusted, and came across this “Supplement Police” article about it:

Nephure Review – Oxalate Reducing Enzyme Powder Health Benefits?

…which honestly, seems to have been written as a paid advertisement. But! It did reference a study, which we were able to look up, and find:

In vitro and in vivo safety evaluation of Nephure™

…which seems to indicate that it was safe (for rats) in all the ways that they checked. They did not, however, check whether it actually reduced oxalate content in spinach or any other food.

The authors did declare a conflict of interest, in that they had a financial relationship with the sponsor of the study, Captozyme Inc.

All in all, it may be better to just have kale instead of spinach:

  • Get Past Executive Dysfunction

    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 mathematics, there is a thing called the “travelling salesman problem”, and it is hard. Not just subjectively; it is classified in mathematical terms as an “NP-hard problem”, wherein NP stands for “nondeterministic polynomial”.

    The problem is: a travelling salesman must visit a certain list of cities, order undetermined, by the shortest possible route that visits them all.

    To work out what the shortest route is involves either very advanced mathematics, or else solving it by brute force, which means measuring every possible combination order (which number gets exponentially larger very quickly after the first few cities) and then selecting the shortest.

    Why are we telling you this?

    Executive dysfunction’s analysis paralysis

    Executive dysfunction is the state of knowing you have things to do, wanting to do them, intending to do them, and then simply not doing them.

    Colloquially, this can be called “analysis paralysis” and is considered a problem of planning and organizing, as much as it is a problem of initiating tasks.

    Let’s give a simple example:

    You wake up in the morning, and you need to go to the bathroom. But the bathroom will be cold, so you’ll want to get dressed first. However, it will be uncomfortable to get dressed while you still need to use the bathroom, so you contemplate doing that first. Those two items are already a closed loop now. You’re thirsty, so you want to have a drink, but the bathroom is calling to you. Sitting up, it’s colder than under the covers, so you think about getting dressed. Maybe you should have just a sip of water first. What else do you need to do today anyway? You grab your phone to check, drink untouched, clothes unselected, bathroom unvisited.

    That was a simple example; now apply that to other parts of your day that have much more complex planning possible.

    This is like the travelling salesman problem, except that now, some things are better if done before or after certain other things. Sometimes, possibly, they are outright required to be done before or after certain other things.

    So you have four options:

    • Solve the problem of your travelling-salesman-like tasklist using advanced mathematics (good luck if you don’t have advanced mathematics)
    • Solve the problem by brute force, calculating all possible variations and selecting the shortest (good luck getting that done the same day)
    • Go with a gut feeling and stick to it (people without executive dysfunction do this)
    • Go towards the nearest item, notice another item on the way, go towards that, notice a different item on the way there, and another one, get stuck for a while choosing between those two, head towards one, notice another one, and so on until you’ve done a very long scenic curly route that has narrowly missed all of your targetted items (this is the executive dysfunction approach).

    So instead, just pick one, do it, pick another one, do it, and so forth.

    That may seem “easier said than done”, but there are tools available…

    Task zero

    We’ve mentioned this before in the little section at the top of our daily newsletter that we often use for tips.

    One of the problems that leads to executive function is a shortage of “working memory”, like the RAM of a computer, so it’s easy to get overwhelmed with lists of things to do.

    So instead, hold only two items in your mind:

    • Task zero: the thing you are doing right now
    • Task one: the thing you plan to do next

    When you’ve completed task zero, move on to task one, renaming it task zero, and select a new task one.

    With this approach, you will never:

    • Think “what did I come into this room for?”
    • Get distracted by alluring side-quests

    Do not get corrupted by the cursed artefact

    In fantasy, and occasionally science fiction, there is a trope: an item that people are drawn towards, but which corrupts them, changes their motivations and behaviors for the worse, as well as making them resistant to giving the item up.

    An archetypal example of this would be the One Ring from The Lord of the Rings.

    It’s easy to read/watch and think “well I would simply not be corrupted by the cursed artefact”.

    And then pick up one’s phone to open the same three apps in a cycle for the next 40 minutes.

    This is because technology that is designed to be addictive hijacks our dopamine processing, and takes advantage of executive dysfunction, while worsening it.

    There are some ways to mitigate this:

    Rebalancing Dopamine (Without “Dopamine Fasting”)

    …but one way to avoid it entirely is to mentally narrate your choices. It’s a lot harder to make bad choices with an internal narrator going:

    • “She picked up her phone absent-mindedly, certain that this time it really would be only a few seconds”
    • “She picked up her phone for the eleventy-third time”
    • “Despite her plan to put her shoes on, she headed instead for the kitchen”

    This method also helps against other bad choices aside from those pertaining to executive dysfunction, too:

    • “Abandoning her plan to eat healthily, she lingered in the confectionary aisle, scanning the shelves for sugary treats”
    • “Monday morning will be the best time to start my new exercise regime”, she thought, for the 35th week so far this year

    Get pharmaceutical or nutraceutical help

    While it’s not for everyone, many people with executive dysfunction benefit from ADHD meds. However, they have their pros and cons (perhaps we’ll do a run-down one of these days).

    There are also gentler options that can significantly ameliorate executive dysfunction, for example:

  • Psychedelics and Psychotherapy – Edited by Dr. Tim Read & Maria Papaspyrou

    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 quick note on authorship, first: this book is edited by the psychiatrist and psychotherapist credited above, but after the introductory section, the rest of the chapters are written by experts on the individual topics.As such, the style will vary somewhat, from chapter to chapter.

    What this book isn’t: “try drugs and feel better!”

    Rather, the book explores the various ways in which assorted drugs can help people to—even if just briefly—shed things they didn’t know they were carrying, or otherwise couldn’t put down, and access parts of themselves they otherwise couldn’t.

    We also get to read a lot about the different roles the facilitator can play in guiding the therapeutic process, and what can be expected out of each kind of experience. This varies a lot from one drug to another, so it makes for very worthwhile reading, if that’s something you might consider pursuing. Knowledge makes for much more informed choices!

    Bottom line: if you’re curious about the therapeutic potential of psychedelics, and want a reference that’s more personal than dry clinical studies, but still more “safe and removed” than diving in by yourself, this is the book for you.

  • Vitamin C (Drinkable) vs Vitamin C (Chewable) – 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 vitamin C (drinkable) to vitamin C (chewable), we picked the drinkable.

    Why?

    First let’s look at what’s more or less the same in each:

    • The usable vitamin C content is comparable
    • The bioavailability is comparable
    • The additives to hold it together are comparable

    So what’s the difference?

    With the drinkable, you also drink a glass of water

    If you’d like to read more about how to get the most out of the vitamins you take, you can do so here:

  • How much does your phone’s blue light really delay your sleep? Relax, it’s just 2.7 minutes

    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 one of the most pervasive messages about technology and sleep. We’re told bright, blue light from screens prevents us falling asleep easily. We’re told to avoid scrolling on our phones before bedtime or while in bed. We’re sold glasses to help filter out blue light. We put our phones on “night mode” to minimise exposure to blue light.

    But what does the science actually tell us about the impact of bright, blue light and sleep? When our group of sleep experts from Sweden, Australia and Israel compared scientific studies that directly tested this, we found the overall impact was close to meaningless. Sleep was disrupted, on average, by less than three minutes.

    We showed the message that blue light from screens stops you from falling asleep is essentially a myth, albeit a very convincing one.

    Instead, we found a more nuanced picture about technology and sleep.

    What we did

    We gathered evidence from 73 independent studies with a total of 113,370 participants of all ages examining various factors that connect technology use and sleep.

    We did indeed find a link between technology use and sleep, but not necessarily what you’d think.

    We found that sometimes technology use can lead to poor sleep and sometimes poor sleep can lead to more technology use. In other words, the relationship between technology and sleep is complex and can go both ways.

    How is technology supposed to harm sleep?

    Technology is proposed to harm our sleep in a number of ways. But here’s what we found when we looked at the evidence:

    • bright screen light – across 11 experimental studies, people who used a bright screen emitting blue light before bedtime fell asleep an average of only 2.7 minutes later. In some studies, people slept better after using a bright screen. When we were invited to write about this evidence further, we showed there is still no meaningful impact of bright screen light on other sleep characteristics including the total amount or quality of sleep
    • arousal is a measure of whether people become more alert depending on what they’re doing on their device. Across seven studies, people who engaged in more alerting or “exciting” content (for example, video games) lost an average of only about 3.5 minutes of sleep compared to those who engaged in something less exciting (for example, TV). This tells us the content of technology alone doesn’t affect sleep as much as we think
    • we found sleep disruption at night (for example, being awoken by text messages) and sleep displacement (using technology past the time that we could be sleeping) can lead to sleep loss. So while technology use was linked to less sleep in these instances, this was unrelated to being exposed to bright, blue light from screens before bedtime.

    Which factors encourage more technology use?

    Research we reviewed suggests people tend to use more technology at bedtime for two main reasons:

    There are also a few things that might make people more vulnerable to using technology late into the night and losing sleep.

    We found people who are risk-takers or who lose track of time easily may turn off devices later and sacrifice sleep. Fear of missing out and social pressures can also encourage young people in particular to stay up later on technology.

    What helps us use technology sensibly?

    Last of all, we looked at protective factors, ones that can help people use technology more sensibly before bed.

    The two main things we found that helped were self-control, which helps resist the short-term rewards of clicking and scrolling, and having a parent or loved one to help set bedtimes.

    We found having a parent or loved one to help set bedtimes encourages sensible use of technology. fast-stock/Shutterstock

    Why do we blame blue light?

    The blue light theory involves melatonin, a hormone that regulates sleep. During the day, we are exposed to bright, natural light that contains a high amount of blue light. This bright, blue light activates certain cells at the back of our eyes, which send signals to our brain that it’s time to be alert. But as light decreases at night, our brain starts to produce melatonin, making us feel sleepy.

    It’s logical to think that artificial light from devices could interfere with the production of melatonin and so affect our sleep. But studies show it would require light levels of about 1,000-2,000 lux (a measure of the intensity of light) to have a significant impact.

    Device screens emit only about 80-100 lux. At the other end of the scale, natural sunlight on a sunny day provides about 100,000 lux.

    What’s the take-home message?

    We know that bright light does affect sleep and alertness. However our research indicates the light from devices such as smartphones and laptops is nowhere near bright or blue enough to disrupt sleep.

    There are many factors that can affect sleep, and bright, blue screen light likely isn’t one of them.

    The take-home message is to understand your own sleep needs and how technology affects you. Maybe reading an e-book or scrolling on socials is fine for you, or maybe you’re too often putting the phone down way too late. Listen to your body and when you feel sleepy, turn off your device.

  • Vaginal Probiotics: What Does The Science Say?

    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!

    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 😎

    ❝Is there any merit to vaginal probiotics?❞

    What a fun question! First let’s break it down, as this could mean two different things:

    1. Probiotics, which you consume, using your mouth, which are marketed as benefiting vaginal health
    2. Probiotics taken as a vaginal pessary/suppository, to act directly there

    The former has limited evidence for it, but generally speaking, improving one’s gut health improves all other areas of health, so it’s not surprising if it helps this too.

    See for example:

    Ingestion of yogurt containing Lactobacillus acidophilus compared with pasteurized yogurt as prophylaxis for recurrent candidal vaginitis and bacterial vaginosis

    Some notes:

    • candidal vaginitis means a yeast infection causing vaginal inflammation
    • bacterial vaginosis means a vaginal bacterial imbalance (generally also featuring vaginal inflammation, though it can be asymptomatic)

    In the latter case, the “imbalance” in question is usually a shortage of Lactobacillus sp. (that is to say, the diverse species of the Lactobacillus genus) resulting in an overgrowth of other kinds of bacteria, which in turn results in changing the vaginal microbiome to make it warmer and more acidic than it should be.

    While a healthy vagina shouldn’t smell of roses, it shouldn’t smell fishy either; if it does, that’s a sign of bacterial vaginosis.

    What it’s supposed to be like: slightly bitter, slightly salty, distinctly umami, along with a cocktail of personal pheromones (and if menstruating or otherwise* vaginally bleeding, then of course add: iron/”metallic”). The pheromones will also reflect any hormonal changes, but should never make anything smell bad, just different.

    *e.g. due to PCOS, fibroids, etc. Note that in the case of PCOS, it may also smell a little different (if it does, then usually: a little more musky), due to often different hormone levels. Again: it still shouldn’t smell bad, though, just different.

    In the above-linked study, taking more live Lactobacillus acidophilus (in yogurt, eating it, with their mouths) improved levels of L. acidophilus in the vagina. While the study authors concluded “this ingestion of yogurt may have reduced episodes of bacterial vaginosis”, which is rather a weak claim, it can be argued that it merely improving the levels of L. acidophilus in the vagina was already a win.

    That was a small (n=42, and only 7 followed through to completion) and old (1996) study, and it bears mentioning that most of the studies into this seem to be small and old, but conclude similarly with weakly positive statements.

    However, it does make a difference what kind of Lactobacillus is used, for example in this next study…

    • L. fermentum RC-14 worked well (90% success rate)
    • L. rhamnosus GR-1 worked somewhat (40% success rate)
    • L. rhamnosus GG did not work (0% success rate)

    So, diversity is key, and getting a wide range of Lactobacillus sp. seems to be a safe bet.

    Short version: enjoying probiotics as part of your diet probably improves vaginal health, just like it improves pretty much everything else.

    See also: Make Friends With Your Gut (You Can Thank Us Later)

    You would think that this would mean that taking probiotics as a vaginal pessary/suppository would be even better, but the results are weaker, as in this study, which produced temporary improvements in about half the study group, with only 3 out of 28 being free of bacterial vaginosis the next month:

    Treatment of bacterial vaginosis with lactobacilli

    This study got better results, with a 61% success rate:

    Effectiveness of Lactobacillus-containing vaginal tablets in the treatment of symptomatic bacterial vaginosis

    Important note

    Do note that this last category, involving topical treatments (i.e., manually introducing Lactobacillus sp. to the vagina) were all in cases of pre-existing bacterial vaginosis, not as a prophylactic and/or general health-improving thing.

    If your vagina seems happy right now, then do not mess with its happy bacterial balance!

    And at all times (regardless of whether it seems happy right now or not): do not douche (it does not need it and will not benefit from it; the vagina is self-cleaning*) as this will wash out many of your Lactobacilli and will do absolutely nothing against any Candida there (C. albicans being a rooted fungus, whereas Lactobacillus is a sausage-shaped bacterium with many tiny appendages but no actual ability to stay put), so Candida will flourish in the Lactobacillus’s absence.

    *by the vagina, we are referring to the vaginal canal. The vulva—the outside part consisting of the two pairs of labia, the glans clitoris, and clitoral hood—are not self-cleaning, and should just be washed gently per your normal bath/shower routine; that’s perfectly fine and good.

    And definitely don’t put any “cleansing” toiletries inside the vagina (or any toiletries at all, for that matter), even if they are sold and marketed for that purpose; they will not help and they will harm.

    Also, due to their neighborliness, messing up the microbiome inside the vagina is a common way to also get Candida inside the urethra:

    How To Avoid Urinary Tract Infections (UTIs)

    One other option

    Finally, unless you have a “very good friend” you have a pressing urge to swap germs with, you might want to leave this one to the scientists, but we share this paper just for interest:

  • The Missing Links – by Drs Phillip Meade & Laura Gallagher

    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.

    This book looks at what goes wrong in projects, why it goes wrong, and how to fill in those “missing links” so that we don’t make the same mistakes that failed projects before us have made.

    Using the Columbia crash (and NASA’s subsequent investigation and organizational overhaul) as an example, Drs Meade and Gallagher take us through the steps to apply NASA’s resultant model to our own projects.

    The book is aimed squarely at business management, but the lessons within are applicable to any kind of project management, whether the project in question is a Fortune 500 merger or a new patio.

    Bottom line is as per the blurb: “you don’t have to be a rocket scientist to apply this model to your organization to create a culture of accountability, inclusivity, and productivity.”
