How Are You, Really? The Free NHS Health Test

We took this surprisingly incisive 10-minute test from the UK’s famous National Health Service—the test is part of the “Better Health” programme, a free-to-all (yes, even those from/in other countries) initiative aimed at keeping people healthy enough to have less need of medical attention.

As one person who took the test wrote:

❝I didn’t expect that a government initiative would have me talking about how I need to keep myself going to be there for the people I love, let alone that a rapid-pace multiple-choice test would elicit these responses and give personalized replies in turn, but here we are❞

It goes beyond covering the usual bases, in that it also looks at what’s most important to you, and why, and what might keep you from doing the things you want/need to do for your health, AND how those obstacles can be overcome.

Pretty impressive for a 10-minute test!

How old are you, in your heart?

Poetic answers notwithstanding (this writer sometimes feels so old, and yet also much younger than she is), there’s a biological answer here, too.

Again free for the use of all*, here’s a heart age calculator.

*It is suitable for you if you are aged 30–95, and do not have a known complicating cardiovascular disease.

It will ask you your (UK) postcode; just leave that field blank if you’re not in the UK; it’ll be fine.

  • As The Summer Gets Hotter Still…

    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

    ❝I would love to see an article about heat dehydrated illness….so much of the US is under hot conditions. I had an fainting sweating episode and now trying to recoup from it. What should we do? Drink water,rest…???❞

    We have done some of this, but it’s always a good one to revisit! Last summer (N. Hemisphere summer), we wrote this:

    Stay Safe From Heat Exhaustion & Heatstroke!

    …and this year, it’s getting hotter still (and is already the hottest summer on record), with certainly much of the US seriously affected, as you say. Next year, it will probably be worse again; climate change is getting predictable like that, and likely will continue until fixed. We are but a health science publication, so we can’t fix the world’s climate, but we can reiterate the above advice, and urge everyone to take it seriously.

    Note: heat exhaustion and heatstroke kill. Yes, we’re including heat exhaustion in that, because by the time you get heat exhaustion, you’re often not in the best state of mind to take the correct steps to avoid the heatstroke that follows.

    To think otherwise would be akin to thinking “falling never killed anyone; it’s only when you stop falling that it’s dangerous”.

    This summer, we did also write this more niche article:

    Surviving Summer While Fat

    …whose advice won’t apply to everyone, but will be helpful to some, and honestly, some of that advice does go for everyone.

    One thing we didn’t write about in those articles that we’ll add here:

    Humidity is dangerous:

    • Dry heat: you sweat, the sweat evaporates, cooling you. As well as losing heat, you’ve also now lost water and salts, which you’ll need to replenish, but your body is operating correctly.
    • Humid heat: you sweat, and now you are just sweaty until further notice. It doesn’t evaporate because the surrounding humidity doesn’t provide the physics for that. Not only are you not losing heat through evaporating sweat, but also, if you’re wearing clothes, that’s now an insulating layer you’re wearing.

    …so that means, watch the humidity as carefully as you watch the temperature, and when it’s high, get extra serious about finding ways to keep yourself cool (e.g. shade, rest, cooling showers etc if you can, that kind of thing).

    Take care!

  • The Immunostimulant Superfood

    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.

    Eat These Greens!

    Chlorella vulgaris, henceforth “chlorella”, is a simple green algae that has a lot of health benefits.

    Note: most of the studies here are for Chlorella vulgaris specifically. However, some are for other species of the Chlorella genus, of which Chlorella vulgaris is by far the most common, hence the name (vulgaris = common). The relevant phytochemical properties appear to be the same regardless.

    Superfood

    While people generally take it as a supplement rather than a food item in any kind of bulk, it is more than 50% protein and contains all 9 essential amino acids.

    As you might expect of a green superfood, it’s also full of many antioxidants, most of them carotenoids, and these pack a punch, for example against cancer:

    Antiproliferative effects of carotenoids extracted from Chlorella ellipsoidea and Chlorella vulgaris on human colon cancer cells

    It also has a lot of vitamins and minerals, and even omega-3.

    Which latter also means it helps improve lipids and is thus particularly…

    Heart healthy

    ❝Daily consumption of Chlorella supplements provided the potential of health benefits reducing serum lipid risk factors, mainly triglycerides and total cholesterol❞

    ~ Dr. Na Hee Ryu et al.

    Read more: Impact of daily Chlorella consumption on serum lipid and carotenoid profiles in mildly hypercholesterolemic adults: a double-blinded, randomized, placebo-controlled study

    Its heart-healthy benefits don’t stop at lipids though, and include blood pressure management, as in this study that found…

    ❝GABA-rich Chlorella significantly decreased high-normal blood pressure and borderline hypertension, and is a beneficial dietary supplement for prevention of the development of hypertension. ❞

    ~ Dr. Morio Shimada et al.

    Read more: Anti-hypertensive effect of gamma-aminobutyric acid (GABA)-rich Chlorella on high-normal blood pressure and borderline hypertension in placebo-controlled double blind study

    About that GABA, if you’re curious about that, check out:

    GABA Against Stress, Anxiety, & More

    May remove heavy metals

    We’re going with “may” for this one as we could only find animal studies so far (probably because most humans don’t have megadoses of heavy metals in them, which makes testing harder).

    Here’s an example animal study, though:

    Enhanced elimination of tissue methyl mercury in [Chlorella]-fed mice

    Immunostimulant

    This one’s clearer, for example in this 8-week study (with humans) that found…

    ❝Serum concentrations of interferon-γ (p<0.05) and interleukin-1β (p<0.001) significantly increased and that of interleukin-12 (p<0.1) tended to increase in the Chlorella group.

    The increments of these cytokines after the intervention were significantly bigger in the Chlorella group than those in the placebo group. In addition, NK cell activities (%) were significantly increased in Chlorella group, but not in Placebo group.

    The increments of NK cell activities (%) were also significantly bigger in the Chlorella group than the placebo group.

    Additionally, changed levels of NK cell activity were positively correlated with those of serum interleukin-1β (r=0.280, p=0.047) and interferon-γ (r=0.271, p<0.005).❞

    ~ Dr. Jung Hyun Kwak et al.

    tl;dr = it boosts numerous different kinds of immune cells

    Read more: Beneficial immunostimulatory effect of short-term Chlorella supplementation: enhancement of natural killer cell activity and early inflammatory response (randomized, double-blinded, placebo-controlled trial)

    PS, if you click though to the study, you may be momentarily alarmed by the first paragraph of the abstract that says “However, there were no direct evidences for the effect of Chlorella supplementation on immune/inflammation response in healthy humans“

    this is from the “Background” section of the abstract, so what they are saying is “before we did this study, nobody had done this yet”.

    So, be assured that the results are worthwhile and compelling.

    Is it safe?

    Based on the studies, it has a good safety profile. However, as it boosts the immune system, you may want to check with your doctor if you have an autoimmune disorder, and/or you are on immunosuppressants.

    And in general, of course always check with your doctor/pharmacist if unsure about any potential drug interactions.

    Want some?

    We don’t sell it, but here for your convenience is an example product on Amazon

    Enjoy!

  • Gut Renovation – by Dr. Roshini Raj, with Sheila Buff

    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.

    Unless we actually feel something going on down there, gut health is an oft-neglected part of overall health—which is unfortunate, because invisible as it may often be, it affects so much.

    Gastroenterologist Dr. Roshini Raj gives us all the need-to-know information, explanations of why things happen the way they do with regard to the gut, and tips, tricks, and hacks to improve matters.

    She also does some mythbusting along the way, and advises about what things don’t make a huge difference, including what medications don’t have a lot of evidence for their usefulness.

    The style is easy-reading pop-science, with plenty of high-quality medical content.

    Reading between the lines, a lot of the book as it stands was probably written by the co-author, Sheila Buff, who is a professional ghostwriter and specializes in working closely with doctors to produce works that are readable and informative to the layperson while still being full of the doctor’s knowledge and expertise. So a reasonable scenario is that Dr. Raj gave her extensive notes, she took it from there, passed it back to her for medical corrections, and they had a little back and forth until it was done. Whatever their setup, the end result was definitely good!

    Bottom line: if you’d like a guide to gut health that’s practical and easy to read, while being quite comprehensive and certainly a lot more than “eat probiotics and fiber”, then this book is a fine choice.

  • The Sucralose News: Scaremongering Or Serious?

    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 news on sucralose?

    These past days the press has been abuzz with frightening tales:

    How true and/or serious is this?

    Firstly, let’s manage expectations. Pineapple juice also breaks down DNA, but is not generally considered a health risk. So let’s keep that in mind, while we look into the science.

    Is sucralose as scary as pineapple juice, or is it something actually dangerous?

    The new study (that sparked off these headlines)

    The much-referenced study is publicly available to read in full—here it is:

    Toxicological and pharmacokinetic properties of sucralose-6-acetate and its parent sucralose: in vitro screening assays

    You may notice that this doesn’t have quite the snappy punchiness of some of the headlines, but let’s break this down, if you’ll pardon the turn of phrase:

    • Toxicological: pertaining to whether or not it has toxic qualities
    • Pharmacokinetic: the science of asking, of chemicals in bodies, “where did it come from; where did it go; what could it do there; what can we know?”
    • Sucralose-6-acetate: an impurity that can be found in sucralose. For perspective, the study found that the sucralose in Splenda contained “up to” 0.67% sucralose-6-acetate.
    • Sucralose: a modified form of sucrose, that makes it hundreds of times sweeter, and non-caloric because the body cannot break it down so it’s treated as a dietary fiber and just passes through
    • In vitro: things are happening in petri dishes, not in animals (human or otherwise), which would be called “in vivo”
    • Screening assays: “we set up a very closed-parameters chemical test, to see what happens when we add this to this” ⇽ oversimplification, but this is the basic format of a screening assay

    Great, now we understand the title, but what about the study?

    Researchers looked primarily at the effects of sucralose-6-acetate and sucralose (together and separately) on epithelial cells (these are very simple cells that are easy to study; conveniently, they are also most of what makes up our intestinal walls). For this, they used a fancy way of replicating human intestinal walls, that’s actually quite fascinating but beyond the scope of today’s newsletter. Suffice it to say: it’s quite good, and/but has its limitations too. They also looked at some in vivo rat studies.

    What they found was…

    Based on samples from the rat feces (somehow this didn’t make it into the headlines), it appears that sucralose may be acetylated in the intestines. What that means is that we, if we are like the rats (definitely not a given, but a reasonable hypothesis), might convert up to 10% of sucralose into sucralose-6-acetate inside us. Iff we do, the next part of the findings become more serious.

    Based on the in vitro simulations, both sucralose and sucralose-6-acetate reduced intestinal barrier integrity at least a little, but sucralose-6-acetate was the kicker when it came to most of the effects—at least, so we (reasonably!) suppose.

    Basically, there’s a lot of supposition going on here but the suppositions are reasonable. That’s how science works; there’s usually little we can know for sure from a single study; it’s when more studies roll in that we start to get a more complete picture.

    What was sucralose-6-acetate found to do? It increased the expression of genes associated with inflammation, oxidative stress, and cancer (granted those three things generally go together). So that’s a “this probably has this end result” supposition.

    More concretely, and which most of the headlines latched onto, it was found (in vitro) to induce cytogenic damage, specifically, of the clastogenic variety (produces DNA strand breaks—so this is different than pineapple’s bromelain and DNA-helicase’s relatively harmless unzipping of genes).

    The dose makes the poison

    So, how much is too much and is that 0.67% something to worry about?

    • Remembering the rat study, it may be more like 10% once our intestines have done their thing. Iff we’re like rats.
    • But, even if it’s only 0.67%, this will still be above the “threshold of toxicological concern for genotoxicity”, of 0.15µg/person/day.
    • On the other hand, the fact that these were in vitro studies is a serious limitation.
    • Sometimes something is very dangerous in vitro, because it’s being put directly onto cells, whereas in vivo we may have mechanisms for dealing with that.

    We won’t know for sure until we get in vivo studies in human subjects, and that may not happen any time soon, if ever, depending on the technical limitations and ethical considerations that sometimes preclude doing certain studies in humans.

    Bottom line:

    • The headlines are written to be scary, but aren’t wrong; their claims are fundamentally true
    • What that means for us as actual humans may not be the same, however; we don’t know yet
    • For now, it is probably reasonable to avoid sucralose just in case

    So, no question/request too big or small

    I have a question: what are the pros and cons of older people (60+) taking creatine every day?

    It depends what else you’re doing, as creatine mostly helps the muscles recover after exercise. So:

    • iff you’re doing resistance training (such as weights or bodyweight training), or HIIT (High Intensity Interval Training), then creatine monohydrate may help you keep at that and keep doing well.
    • if you’re just doing light-to-moderate exercises, you might not get much benefit from creatine!

    The topic merits diving deeper though, so we’ll queue that for one of our “Research Review Monday” days!

    I wanted to ask if you think marine collagen is decent to take. I’ve heard a lot of bad press about it

    We don’t know what you’ve heard, but generally speaking it’s been found to be very beneficial to bones, joints, and skin! We wrote about it quite recently on a “Research Review Monday”:

    See: We Are Such Stuff As Fish Are Made Of

    Natural alternatives to medication for depression?

    Great question! We did a mean feature a while back, but we definitely have much more to say! We’ll do another main feature soon, but in the meantime, here’s what we previously wrote:

    See: The Mental Health First-Aid That You’ll Hopefully Never Need

    ^This covers not just the obvious, but also why the most common advice is not helpful, and practical tips to actually make manageable steps back to wellness, on days when “literally just survive the day” is one’s default goal.

    I am now in the “aging” population. A great concern for me is Alzheimers. My father had it and I am so worried. What is the latest research on prevention?

    One good thing to note is that while Alzheimer’s has a genetic component, it doesn’t appear to be hereditary per se. Still, good to be on top of these things, and it’s never too early to start with preventive measures!

    You might like a main feature we did on this recently:

    Side effects of statins, are they worth it? Depression, are antidepressants worth it?

    About statins, that depends a lot on you, your circumstances, and—as it happens—your gender. We covered this in a main feature recently, but a short answer is: for most people, they may not be the best first choice, and could even make things worse. For some people, however, they really are just what’s needed.

    • Factors that make them more likely better for you: being a man, or having atherosclerosis
    • Factors that make them more likely worse for you: being a woman in general

    Check out the main feature we did: Statins: His & Hers?

    As for antidepressants? That depends a lot on you, your physiology, your depression, your circumstances, and more. We’ll definitely do a main feature on that sometime soon, as there’s a lot that most people don’t know!

    Hair growth strategies for men combing caffeine and minoxidil?

    Well, the strategy for that is to use caffeine and minoxidil! Some more specific tips, though:

    • Both of those things need to be massaged (gently!) into your scalp especially around your hairline.
      • In the case of caffeine, that boosts hair growth. No extra thought or care needed for that one.
      • In the case of minoxidil, it reboots the hair growth cycle, so if you’ve only recently started, don’t be surprised (or worried) if you see more shedding in the first three months. It’s jettisoning your old hairs because new ones were just prompted (by the minoxidil) to start growing behind them. So: it will get briefly worse before it gets better, but then it’ll stay better… provided you keep using it.
    • If you’d like other options besides minoxidil, finasteride is a commonly prescribed oral drug that blocks the conversion of testosterone to DHT, which latter is what tells your hairline to recede.
    • If you’d like other options besides prescription drugs, saw palmetto performs comparably to finasteride (and works the same way).
      • You may also want to consider biotin supplementation if you don’t already enjoy that
    • Consider also using a dermaroller on your scalp. If you’re unfamiliar, this is a device that looks like a tiny lawn aerator, with many tiny needles, and you roll it gently across your skin.
      • It can be used for promoting hair growth, as well as for reducing wrinkles and (more slowly) healing scars.
      • It works by breaking up the sebum that may be blocking new hair growth, and also makes the skin healthier by stimulating production of collagen and elastin (in response to the thousands of microscopic wounds that the needles make).
      • Sounds drastic, but it doesn’t hurt and doesn’t leave any visible marks—the needles are that tiny. Still, practise good sterilization and ensure your skin is clean when using it.

    See: How To Use A Dermaroller ← also explains more of the science of it

    PS: this question was asked in the context of men, but the information goes the same for women suffering from androgenic alepoceia—which is a lot more common than most people think!

  • It’s Not Hysteria – by Dr. Karen Tan

    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.

    Firstly, who this book is aimed at: in case it wasn’t clear, this book assumes you have, or at least have had, a uterus. If that’s not you, then well, it’ll still be an interesting read but it won’t be about your reproductive health.

    Secondly, about that “reproductive health”: it’s mostly not actually about reproductive health literally, but rather, the health of one’s reproductive organs and the things that they affect—which is a lot more than the ability to reproduce!

    Dr. Tang takes us on a (respectably in-depth) tour of the relevant anatomy, before moving on to physiology, before continuing to pathology (i.e. things that can go wrong, and often do), and finally various treatment options, including elective procedures, and the pros and cons thereof.

    She also talks the reader through talking about things with gynecologists and other healthcare providers, and making sure concerns are not dismissed out-of-hand (something that happens a lot, of course).

    The style throughout is quite detailed prose, but without being difficult at all to read, and (assuming one is interested in the topic) it’s very engaging.

    Bottom line: if you would like to know more about uteri and everything that is (or commonly/unfortunately) can be attached to them, the effects they have on the rest of the body and health, and what can be done about things not being quite right, then this is a good book for that.
