So, no question/request too big or small

❝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:

    We Are Such Stuff As Bottles Are Made Of

    We’ve written before about PFAS, often found in non-stick coatings and the like:

    PFAS Exposure & Cancer: The Numbers Are High

    Today we’re going to be talking about microplastics & nanoplastics!

    What are microplastics and nanoplastics?

    Firstly, they’renot just the now-banned plastic microbeads that have seen some use is toiletries (although those are classified as microplastics too).

    Many are much smaller than that, and if they get smaller than a thousandth of a millimeter, then they get the additional classification of “nanoplastic”.

    In other words: not something that can be filtered even if you were to use a single-micron filter. The microplastics would still get through, for example:

    Scientists find about a quarter million invisible nanoplastic particles in a liter of bottled water

    And unfortunately, that’s bad:

    ❝What’s disturbing is that small particles can appear in different organs and may cross membranes that they aren’t meant to cross, such as the blood-brain barrier❞

    ~ Dr. Zoie Diana

    Note: they’re crossing the same blood-brain barrier that many of our nutrients and neurochemicals are too big to cross.

    These microplastics are also being found in arterial plaque

    What makes arterial plaque bad for the health is precisely its plasticity (the arterial walls themselves are elastic), so you most certainly do not want actual plastic being used as part of the cement that shouldn’t even be lining your arteries in the first place:

    Microplastics found in artery plaque linked with higher risk of heart attack, stroke and death

    ❝In this study, patients with carotid artery plaque in which MNPs were detected had a higher risk of a composite of myocardial infarction, stroke, or death from any cause at 34 months of follow-up than those in whom MNPs were not detected❞

    ~ Dr. Raffaele Marfella et al.

    (MNP = Micro/Nanoplastics)

    Source: Microplastics and Nanoplastics in Atheromas and Cardiovascular Events

    We don’t know how bad this is yet

    There are various ways this might not be as bad as it looks (the results may not be repeated, the samples could have been compromised, etc), but also, perhaps cynically but nevertheless honestly, it could also be worse than we know yet—only more experiments being done will tell us which.

    In the meantime, here’s a rundown of what we do and don’t know:

    Study links microplastics with human health problems—but there’s still a lot we don’t know

  • Vaccines and cancer: The myth that won’t die

    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.

    Two recent studies reported rising cancer rates among younger adults in the U.S. and worldwide. This prompted some online anti-vaccine accounts to link the studies’ findings to COVID-19 vaccines. 

    But, as with other myths, the data tells a very different story. 

    What you need to know 

    • Baseless claims that COVID-19 vaccines cause cancer have persisted online for several years and gained traction in late 2023.
    • Two recent reports finding rising cancer rates among younger adults are based on pre-pandemic cancer incidence data. Cancer rates in the U.S. have been on the rise since the 1990s.
    • There is no evidence of a link between COVID-19 vaccination and increased cancer risk.

    False claims about COVID-19 vaccines began circulating months before the vaccines were available. Chief among these claims was misinformed speculation that vaccine mRNA could alter or integrate into vaccine recipients’ DNA. 

    It does not. But that didn’t prevent some on social media from spinning that claim into a persistent myth alleging that mRNA vaccines can cause or accelerate cancer growth. Anti-vaccine groups even coined the term “turbo cancer” to describe a fake phenomenon of abnormally aggressive cancers allegedly linked to COVID-19 vaccines. 

    They used the American Cancer Society’s 2024 cancer projection—based on incidence data through 2020—and a study of global cancer trends between 1999 and 2019 to bolster the false claims. This exposed the dishonesty at the heart of the anti-vaccine messaging, as data that predated the pandemic by decades was carelessly linked to COVID-19 vaccines in viral social media posts.

    Some on social media cherry-pick data and use unfounded evidence because the claims that COVID-19 vaccines cause cancer are not true. According to the National Cancer Institute and American Cancer Society, there is no evidence of any link between COVID-19 vaccines and an increase in cancer diagnosis, progression, or remission. 

    Why does the vaccine cancer myth endure?

    At the root of false cancer claims about COVID-19 vaccines is a long history of anti-vaccine figures falsely linking vaccines to cancer. Polio and HPV vaccines have both been the target of disproven cancer myths. 

    Not only do HPV vaccines not cause cancer, they are one of only two vaccines that prevent cancer.

    In the case of polio vaccines, some early batches were contaminated with simian virus 40 (SV40), a virus that is known to cause cancer in some mammals but not humans. The contaminated batches were discovered, and no other vaccine has had SV40 contamination in over 60 years

    Follow-up studies found no increase in cancer rates in people who received the SV40-contaminated polio vaccine. Yet, vaccine opponents have for decades claimed that polio vaccines cause cancer.

    Recycling of the SV40 myth

    The SV40 myth resurfaced in 2023 when vaccine opponents claimed that COVID-19 vaccines contain the virus. In reality, a small, nonfunctional piece of the SV40 virus is used in the production of some COVID-19 vaccines. This DNA fragment, called the promoter, is commonly used in biomedical research and vaccine development and doesn’t remain in the finished product. 

    Crucially, the SV40 promoter used to produce COVID-19 vaccines doesn’t contain the part of the virus that enters the cell nucleus and is associated with cancer-causing properties in some animals. The promoter also lacks the ability to survive on its own inside the cell or interact with DNA. In other words, it poses no risk to humans.

    Over 5.6 billion people worldwide have received COVID-19 vaccines since December 2020. At that scale, even the tiniest increase in cancer rates in vaccinated populations would equal hundreds of thousands of excess cancer diagnoses and deaths. The evidence for alleged vaccine-linked cancer would be observed in real incidence, treatment, and mortality data, not social media anecdotes or unverifiable reports.

  • The Evidence-Based Skincare That Beats Product-Specific Hype

    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 million videos on YouTube will try to sell you a 17-step skincare routine, or a 1-ingredient magical fix that’s messy and inconvenient enough you’ll do it once and then discard it. This one takes a simple, scientific approach instead.

    The Basics That Count

    Ali Abdaal, known for his productivity hacks channel, enlisted the help of his friend, dermatologist Dr. Usama Syed, who recommends the following 3–4 things:

    1. Moisturize twice per day. Skin acts as a barrier, locking in moisture and protecting against irritants. Moisturizers replenish fats and proteins, maintaining this barrier and preventing dry, inflamed, and itchy skin. He uses CeraVe, but if you have one you know works well with your skin, stick with that, because skin comes in many varieties and yours might not be like his.
    2. Use sunscreen every day. Your phone’s weather app should comment on your local UV index. If it’s “moderate” or above, then sunscreen is a must—even if you aren’t someone who burns easily at all, the critical thing here is avoiding UV radiation causing DNA mutations in skin cells, leading to wrinkles, dark spots, and potentially skin cancer. Use a broad-spectrum sunscreen, ideally SPF 50.
    3. Use a retinoid. Retinoids are vitamin A-based and offer anti-aging benefits by promoting collagen growth, reducing pigmentation, and accelerating skin cell regeneration. Retinols are weaker, over-the-counter options, while stronger retinoids may require a prescription. Start gently with low dosage, whatever you choose, as initially they can cause dryness or sensitivity, before making everything better. He recommends adapalene as a starter retinoid (such as Differen gel, to give an example brand name).
    4. Optional: use a cleanser. Cleansers remove oils and dirt that water alone can’t. He recommends using a hydrating cleanser, to avoid stripping natural healthy oils as well as unwanted ones. That said, a cleanser is probably only beneficial if your skin tends towards the oily end of the dry-to-oily spectrum.

  • Butternut Squash vs Pumpkin – Which is Healthier?

    Our Verdict

    When comparing butternut squash to pumpkin, we picked the butternut squash.

    Why?

    Both are great! But the butternut squash manages a moderate win in most categories.

    In terms of macros, butternut squash has more of everything except water. Most notably, it has more protein and more fiber. Yes, more carbs too, but the fiber content means that it also has the lower glycemic index, by quite a bit.

    When it comes to vitamins, pumpkin does have a little more of vitamin B1 and a lot more of vitamin E, while butternut squash has more of vitamins B3, B5, B9, C, K, and choline. They’re about equal in the other vitamins they both contain. A fair win for butternut squash.

    In the category of minerals, butternut squash has more calcium, magnesium, manganese, and selenium, while pumpkin has more copper, iron, and phosphorus. They’re about equal in potassium and zinc. A marginal win for butternut squash.

    Adding up the strong win, the fair win, and the marginal win, makes for an easy overall win for butternut squash!

    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

    Q: What’s a healthy sex drive for someone in their 50s?

    A: If you’re happy with it, it’s healthy! If you’re not, it’s not.

    This means… If you’re not (happy) and thus it’s not (healthy), you have two main options:

    1. Find a way to be happier without changing it (i.e., change your perspective)
    2. Find a way to change your sex drive (presumably: “increase it”, but we don’t like to assume)

    There are hormonal and pharmaceutical remedies that may help (whatever your sex), so do speak with your doctor/pharmacist.

    Additionally, if a boost to sex drive is what’s wanted, then almost anything that is good for your heart will help.

    We wrote about heart health yesterday:

  • Make Your Negativity Work For You

    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.

    What’s The Right Balance?

    We’ve written before about positivity the pitfalls and perils of toxic positivity:

    How To Get Your Brain On A More Positive Track (Without Toxic Positivity)

    …as well as the benefits that can be found from selectively opting out of complaining:

    A Bone To Pick… Up And Then Put Back Where We Found It

    So… What place, if any, does negativity usefully have in our lives?

    Carrot and Stick

    We tend to think of “carrot and stick” motivation being extrinsic, i.e. there is some authority figure offering is reward and/or punishment, in response to our reactions.

    In those cases when it really is extrinsic, the “stick” can still work for most people, by the way! At least in the short term.

    Because in the long term, people are more likely to rebel against a “stick” that they consider unjust, and/or enter a state of learned helplessness, per “I’ll never be good enough to satisfy this person” and give up trying to please them.

    But what about when you have your own carrot and stick? What about when it comes to, for example, your own management of your own healthy practices?

    Here it becomes a little different—and more effective. We’ll get to that, but first, bear with us for a touch more about extrinsic motivation, because here be science:

    We will generally be swayed more easily by negative feelings than positive ones.

    For example, a study was conducted as part of a blood donation drive, and:

    • Group A was told that their donation could save a life
    • Group B was told that their donation could prevent a death

    The negative wording given to group B boosted donations severalfold:

    Read the paper: Life or Death Decisions: Framing the Call for Help

    We have, by the way, noticed a similar trend—when it comes to subject lines in our newsletters. We continually change things up to see if trends change (and also to avoid becoming boring), but as a rule, the response we get from subscribers is typically greater when a subject line is phrased negatively, e.g. “how to avoid this bad thing” rather than “how to have this good thing”.

    How we can all apply this as individuals?

    When we want to make a health change (or keep up a healthy practice we already have)…

    • it’s good to note the benefits of that change/practice!
    • it’s even better to note the negative consequences of not doing it

    For example, if you want to overcome an addiction, you will do better for your self-reminders to be about the bad consequences of using, more than the good consequences of abstinence.

    See also: How To Reduce Or Quit Alcohol

    This goes even just for things like diet and exercise! Things like diet and exercise can seem much more low-stakes than substance abuse, but at the end of the day, they can add healthy years onto our lives, or take them off.

    Because of this, it’s good to take time to remember, when you don’t feel like exercising or do feel like ordering that triple cheeseburger with fries, the bad outcomes that you are planning to avoid with good diet and exercise.

    Imagine yourself going in for that quadruple bypass surgery, asking yourself whether the unhealthy lifestyle was worth it. Double down on the emotions; imagine your loved ones grieving your premature death.

    Oof, that was hard-hitting

    It was, but it’s effective—if you choose to do it. We’re not the boss of you! Either way, we’ll continue to send the same good health advice and tips and research and whatnot every day, with the same (usually!) cheery tone.

    One last thing…

    While it’s good to note the negative, in order to avoid the things that lead to it, it’s not so good to dwell on the negative.

    So if you get caught in negative thought spirals or the like, it’s still good to get yourself out of those.
