Top 10 Causes Of High Blood Pressure

As Dr. Frita Fisher explains, these are actually the top 10 known causes of high blood pressure. Number zero on the list would be “primary hypertension”, which means high blood pressure with no clear underlying cause.

Superficially, this feels a little like the sometime practice of writing the catch-all “heart failure” as the cause of death on a death certificate, because yes, that heart sure did stop beating. But in reality, primary hypertension is most likely often caused by such things as unmanaged chronic stress—something that doesn’t show up on most health screenings.

Dr. Fisher’s Top 10

  • Thyroid disease: both hyperthyroidism and hypothyroidism can cause high blood pressure.
  • Obstructive sleep apnea: characterized by snoring, daytime sleepiness, and headaches, this condition can lead to hypertension.
  • Chronic kidney disease: diseases ranging from diabetic nephropathy to renal vascular disease can cause high blood pressure.
  • Elevated cortisol levels: conditions like Cushing’s syndrome or disease, which involve high cortisol levels, can lead to hypertension—as can a lifestyle with a lot of chronic stress, but that’s less readily diagnosed as such than something one can tell from a blood test.
  • Elevated aldosterone levels: excess aldosterone from the adrenal glands causes the body to retain salt and water, increasing blood pressure, because more stuff = more pressure.
  • Brain tumor: tumors that increase intracranial pressure can cause a rise in blood pressure to ensure adequate brain perfusion. In these cases, the hypertension is keeping you alive—unless it kills you first. If this seems like a strange bodily response, remember that our bodily response to an infection is often fever, to kill off the infection which can’t survive at such high temperatures (but neither can we, so it becomes a game of chicken with our life on the line), so sometimes our body does kill us with one thing while trying to save us from another.
  • Coarctation of the aorta: this congenital heart defect results in narrowing of the aorta, leading to hypertension, especially in the upper body.
  • Pregnancy: pregnancy can either induce or worsen existing hypertension.
  • Obesity: excess weight increases blood flow and pressure on arteries, raising the risk of hypertension and associated conditions, e.g. diabetes etc.
  • Drugs: certain medications and recreational drugs (including, counterintuitively, alcohol!) can elevate blood pressure.

  • Oats vs Pearl Barley – 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 oats to pearl barley, we picked the oats.

    Why?

    In terms of macronutrients first, pearl barley has about three times the carbs for only the same amount of protein and fiber—if it had been regular barley rather than pearl parley, it’d have about twice the fiber, but pearl barley has had the fibrous husk removed.

    Vitamins really set the two part, though: oats have a lot more (60x more) vitamin A, and notably more of vitamins B1, B2, B3, B5, B6, and B9, as well as 6x more vitamin E. In contrast, pearl barley has a little more vitamin K and choline. An easy win for oats in this section.

    In the category of minerals, oats have over 6x more calcium, 3x more iron, and a little more magnesium, manganese, and phosphorus. Meanwhile, pearl barley boats a little more copper, potassium, selenium, and zinc. So, a more moderate win for oats in this category.

    They are both very good for the gut, unless you have a gluten intolerance/allergy, in which case, oats are the only answer here since pearl barley, as per barley in general, has gluten as its main protein (oats, meanwhile, do not contain gluten, unless by cross-contamination).

    Adding up all the sections, this one’s a clear win for oats.

  • Blood-Sugar Balancing Beetroot Cutlets

    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.

    These beetroot cutlets are meaty and proteinous and fibrous and even have a healthy collection of fats, making these much better for your heart and blood than an animal-based equivalent.

    You will need

    • 1 can kidney beans, drained and rinsed (or 1 cup same, cooked, drained, and rinsed)
    • ½ cup chopped roasted or steamed beetroot, blotted dry
    • ½ cup chopped walnuts (if allergic, substitute with ¼ cup pumpkin seeds)
    • ½ cup cooked (ideally: mixed) grains of your choice (if you need gluten-free, there are plenty of gluten-free grains and pseudocereals)
    • ¼ cup finely chopped onion
    • ¼ bulb garlic, minced or crushed
    • 2 tbsp nutritional yeast
    • 2 tbsp ground flaxseeds
    • 2 tbsp ground chia seeds
    • 2 tsp tomato purée
    • 1 tsp black pepper
    • ½ tsp white miso paste
    • ½ tsp smoked paprika
    • ½ tsp cayenne pepper
    • ¼ tsp MSG or ½ tsp low-sodium salt

    Method

    (we suggest you read everything at least once before doing anything)

    1) Combine the beetroot, beans, walnuts, grains, and onion in a food processor, and process until a coarse even mixture.

    2) Add the remaining ingredients and process to mix thoroughly.

    3) Transfer the mixture to a clean work surface and divide into six balls. If the structural integrity is not good (i.e. too soft), add a little more of any or all of these ingredients: chopped walnuts, ground flax, ground chia, nutritional yeast.

    4) Press the balls firmly into cutlets, and refrigerate for at least 1 hour, but longer is even better if you have the time. Alternatively, if you’d like to freeze them for later use, then this is the point at which to do that.

    5) Preheat the oven to 375℉ / 190℃.

    6) Roast the cutlets on a baking tray lined with baking paper, for about 30 minutes, turning over carefully with a spatula halfway through. They should be firm when done; if they’re not, give them a little longer.

    7) Serve hot, for example on a bed of greens and with a drizzle of aged balsamic vinegar.

    Enjoy!

  • Fall Special

    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.

    Some fall-themed advice…

    It is now, nominally at least, fall. We’re going to talk about the other kind of “fall” though, the kind that results in broken hips and more.

    If you’re thinking “not me; that happens to older more infirm people”, rest assured, it can and statistically probably will happen to you at some point. So, how to play the odds?

    First, be robust!

    We may not be able to make ourselves like children who bounce easily, but we also don’t have to crumble into dust at the slightest knock, either. There are two important ways we can start to make ourselves robust from the inside out, and they are simple: diet and exercise.

    “But I don’t have osteoporosis”—great! But osteoporosis is preceded by osteopenia, which is generally asymptomatic at first, and also if we’re not very careful about it, we will lose about 1% bone density per year from the age of about 35 onwards, with that rate of loss climbing sharply from the age of 50 onwards, and even more steeply in cases of untreated menopause.

    So in other words, don’t take your bone strength for granted; there’s a first time for everything, and you don’t want to find out the hard (and yet, dare we say it, brittle) way.

    Second, be dynamic!

    Be able to fall and get up safely. If your later life is going to be a triathlon of things you need to train for now, then being able to fall and get up safely should be at the top of the list.

    Being able to “deep squat” will help you a lot here, in being able to get up with minimal (or no) use of your hands. We shared a great instructional video about this last week.

    It also means that the more your lower body can still take your weight while your torso is closer to the ground (without your legs buckling and collapsing, for instance), the softer and gentler you’ll hit the floor if you do fall, because the final “drop” will be from a lower height.

    If at all possible, consider taking some classes of a martial art that involves safely falling—aikido is typically the softest and gentlest and is famously great for people of all ages, but judo or jujitsu will suffice if aikido isn’t available where you are. You don’t have to get a black belt (unless you want to), and any decent instructor will be happy to guide you through the basics of safely falling and then send you on your merry way, if that’s all you wanted.

    The benefits of this are twofold:

    • Obviously, if you fall, you will have better technique and thus be less likely to incur injury
    • As you are falling, you will be less afraid, and thus less likely to tense up mid-fall (tensing up will exacerbate any falling injury)

    Third, be balanced!

    Spending even just a few minutes each day working on your balance can go a long way.

    Standing on one leg (and then the other) is a very good obvious starting point. Please, do so safely. The shower is not the best place to take up this practice, for instance. A nice safe grassy area is great. Your carpeted living room or bedroom is next-best.

    Another great approach is the practice of bāguàzhǎng circle-walking.

    Bāguà is tai chi’s lesser-known cousin, and those arts are two of the three main schools of wǔdāngquán. But, fear not, you don’t have to don orange robes and live atop the Wudang mountains to get what you need in this case.

    To give a text-based summary: bāguàzhǎng circle-walking involves walking in a small circle, with a low center of gravity, moving one’s weight very purposefully from one leg to the other, keeping complete stability the whole time that one is (often!) on one leg.

    Once you get good at this, you’ll see that this is essentially a super-enhanced version of the “standing on one leg” exercise, because it’s about keeping balance while on one leg, and/but while moving also.

    Naturally, if you do get good at this, you’ll be very unlikely to fall in the first place.

    Here’s a visual primer. This video will show the basic footwork, and the video that follows it (it’ll prompt you if you want to watch it) shows how to bring it up to a standard walking speed, without losing fluidity of movement:

    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.

    Let’s get the criticism out of the way first: notwithstanding the subtitle promising over 100 recipes, there are about 80-odd here, if we discount recipes that are no-brainer things like smoothies, sides such as for example “roasted garlic”, or meta-ingredients such as oat flour (instructions: blend the oats and you get oat flour).

    The other criticism is more subjective: if you are like this reviewer, you will want to add more seasonings than recommended to most of the recipes. But that’s easy enough to do.

    As for the rest: this is a very healthy cookbook, and quite wide-ranging and versatile, with recipes that are homely, with a lot of emphasis on comfort foods (but still, healthy), though certainly some are perfectly worthy of entertaining too.

    A nice bonus of this book is that it offers a lot of available substitutions (much like we do at 10almonds), and also ways of turning the recipe into something else entirely with just a small change. This trait more than makes up for the slight swindle in terms of number of recipes, since some of the recipes have bonus recipes snuck in.

    Bottom line: if you’d like to broaden your plant-based cooking range, this book is a fine option for expanding your repertoire.

  • The Science and Technology of Growing Young – by Sergey Young

    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.

    There are a lot of very optimistic works out there that promise the scientific breakthroughs that will occur very soon. Even amongst the hyperoptimistic transhumanism community, there is the joke of “where’s my flying car?” Sometimes prefaced with “Hey Ray, quick question…” as a nod to (or sometimes, direct address to) Ray Kurzweil, the Google computer scientist and futurist.

    So, how does this one measure up?

    Our author, Sergey Young, is not a scientist, but an investor with fingers in many pies. Specifically, pies relating to preventative medicine and longevity. Does that make him an unreliable narrator? Not necessarily, but it means we need to at least bear that context in mind.

    But, also, he’s investing in those fields because he believes in them, and wants to benefit from them himself. In essense, he’s putting his money where his mouth is. But, enough about the author. What of the book?

    It’s a whirlwind tour of the main areas of reseach and development, in the recent past, the present, and the near future. He talks about problems, and compelling solutions to problems.

    If the book has a weak point, it’s that it doesn’t really talk about the problems to those solutions—that is, what can still go wrong. He’s excited about what we can do, and it’s somebody else’s job to worry about pitfalls along the way.

    As to the “and what you can do now?” We’ll summarize:

    • Mediterranean diet, mostly plant-based
    • Get moderate exercise daily
    • Get good sleep
    • Don’t drink or smoke
    • Get your personal health genomics data
    • Get regular medical check-ups
    • Look after your mental health too

    Bottom line: this is a great primer on the various avenues of current anti-aging research and development, with discussion ranging from the the technological to the sociological. It has some health tips too, but the real meat of the work is the insight into the workings of the longevity industry.

  • What Is Earwax & Should You Get Rid Of It?

    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.

    Earwax (cerumen) forms in the outer ear canal when dead skin cells mix with oily sweat (a specialty of the apocrine glands) and sebum, a fatty substance mostly associated with facial oiliness. But, does it have a purpose, or is it just a waste product?

    Nature is (mostly) best in this case

    Earwax plays an important role in ear health, acting as a natural lubricant that prevents dryness and itchiness, trapping debris and microbes, and forming a protective barrier for the ear canal. It even contains proteins that help fight bacterial infections.

    As for removal: the body has a natural mechanism for removing excess earwax: as skin cells grow, they migrate outward, carrying earwax with them.

    In contrast, manual removal of earwax can do more harm than good. Using swabs or other items often pushes wax deeper, risks damaging the ear canal, and disrupts its protective barrier, potentially leading to infection.

    Ear candling, which claims to extract earwax, not only does not work (its main premise has been actively disproven and clinical evidence shows unequivocally that it doesn’t work by any mysterious method either; it just plain doesn’t work), but also can cause injuries and will tend to leave more harmful debris behind than was there originally.

    For those prone to earwax buildup, over-the-counter eardrops can help soften wax for natural removal, and medical professionals have safe methods to clear blockages if necessary.

    To maintain ear health, it’s best to clean only the outer ear with a damp cloth, limit the use of earplugs or earbuds, and generally leave earwax alone unless it causes discomfort or hearing issues.
