Hypertension kills a lot of people, and does so with little warning—it can be asymptomatic before it gets severe enough to cause harm, and once it causes harm, well, one heart attack or stroke is already one too many.

Aimed more squarely at people in the 35–45 danger zone (young enough to not be getting regular blood pressure checks, old enough that it may have been building up for decades), this is a very good primer on blood pressure, factors affecting it, what goes wrong, what to do about it, and how to make a good strategy for managing it for life.

The style is easy-reading, making this short (91 pages) book a very quick read, but an informative one.

Bottom line: if you are already quite knowledgeable about blood pressure and blood pressure management, this one’s probably not for you. But if you’re in the category of “what do those numbers mean again?”, then this is a very handy book to have, to get you up to speed so that you can handle things as appropriate.

  • Going for a bushwalk? 3 handy foods to have in your backpack (including muesli bars)

    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 time of year, many of us love to get out and spend time in nature. This may include hiking through Australia’s many beautiful national parks.

    Walking in nature is a wonderful activity, supporting both physical and mental health. But there can be risks and it’s important to be prepared.

    You may have read the news about hiker, Hadi Nazari, who was recently found alive after spending 13 days lost in Kosciuszko National Park.

    He reportedly survived for almost two weeks in the Snowy Mountains region of New South Wales by drinking fresh water from creeks, and eating foraged berries and two muesli bars.

    So next time you’re heading out for a day of hiking, what foods should you pack?

    Here are my three top foods to carry on a bushwalk that are dense in nutrients and energy, lightweight and available from the local grocery store.

    1. Muesli bars

    Nazari reportedly ate two muesli bars he found in a mountain hut. Whoever left the muesli bars there made a great choice.

    Muesli bars come individually wrapped, which helps them last longer and makes them easy to transport.

    They are also a good source of energy. Muesli bars typically contain about 1,5001,900 kilojoules per 100 grams. The average energy content for a 35g bar is about 614kJ.

    This may be a fraction of what you’d usually need in a day. However, the energy from muesli bars is released at a slow to moderate pace, which will help keep you going for longer.

    Muesli bars are also packed with nutrients. They contain all three macronutrients (carbohydrate, protein and fat) that our body needs to function. They’re a good source of carbohydrates, in particular, which are a key energy source. An average Australian muesli bar contains 14g of whole grains, which provide carbohydrates and dietary fibre for long-lasting energy.

    Muesli bars that contain nuts are typically higher in fat (19.9g per 100g) and protein (9.4g per 100g) than those without.

    Fat and protein are helpful for slowing down the release of energy from foods and the protein will help keep you feeling full for longer.

    There are many different types of muesli bars to choose from. I recommend looking for those with whole grains, higher dietary fibre and higher protein content.

    2. Nuts

    Nuts are nature’s savoury snack and are also a great source of energy. Cashews, pistachios and peanuts contain about 2,300-2,400kJ per 100g while Brazil nuts, pecans and macadamias contain about 2,700-3,000kJ per 100g. So a 30g serving of nuts will provide about 700-900kJ depending on the type of nut.

    Just like muesli bars, the energy from nuts is released slowly. So even a relatively small quantity will keep you powering on.

    Nuts are also full of nutrients, such as protein, fat and fibre, which will help to stave off hunger and keep you moving for longer.

    When choosing which nuts to pack, almost any type of nut is going to be great.

    Peanuts are often the best value for money, or go for something like walnuts that are high in omega-3 fatty acids, or a nut mix.

    Whichever nut you choose, go for the unsalted natural or roasted varieties. Salted nuts will make you thirsty.

    Nut bars are also a great option and have the added benefit of coming in pre-packed serves (although nuts can also be easily packed into re-usable containers).

    If you’re allergic to nuts, roasted chickpeas are another option. Just try to avoid those with added salt.

    3. Dried fruit

    If nuts are nature’s savoury snack, fruit is nature’s candy. Fresh fruits (such as grapes, frozen in advance) are wonderfully refreshing and perfect as an everyday snack, although can add a bit of weight to your hiking pack.

    So if you’re looking to reduce the weight you’re carrying, go for dried fruit. It’s lighter and will withstand various conditions better than fresh fruit, so is less likely to spoil or bruise on the journey.

    There are lots of varieties of dried fruits, such as sultanas, dried mango, dried apricots and dried apple slices.

    These are good sources of sugar for energy, fibre for fullness and healthy digestion, and contain lots of vitamins and minerals. So choose one (or a combination) that works for you.

    Don’t forget water

    Next time you head out hiking for the day, you’re all set with these easily available, lightweight, energy- and nutrient-dense snacks.

    This is not the time to be overly concerned about limiting your sugar or fat intake. Hiking, particularly in rough terrain, places demands on your body and energy needs. For instance, an adult hiking in rough terrain can burn upwards of about 2,000kJ per hour.

    And of course, don’t forget to take plenty of water.

    Having access to even limited food, and plenty of fresh water, will not only make your hike more pleasurable, it can save your life.

  • Eating on the Wild Side: – by Jo Robinson

    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 author is an investigative journalist, and it shows here, as she leaves no stone unturned in her quest for the truth in the face of many food myths.

    She covers a lot of “popular wisdom” things that are varyingly true or false, or sometimes even both—in the case of food lore that’s a good rule of thumb, but has notable exceptions (e.g. “more colorful and/or darker-colored fruits/vegetables contain more nutrients”, which is a very good rule of thumb until one meets a cauliflower, for example).

    She also covers food preparation myths, and how, to give one example, in spite of the popularity of “less cooked is better”, in some cases certain cooking methods will indeed destroy nutrients; in others, certain cooking methods will improve nutritional availability. Either by destroying an adjacent antinutrient (e.g. phytates), or by breaking something down into a more manageable form that our body can absorb. Knowing which is which, is important.

    The book is organized by kinds of food, and does exclusively cover plants, but there’s more than enough material for any omnivore to enjoy.

    The style is… Journalistic, it would be fair to say. Which is not surprising, given the author. But it means that it is written in a fairly narrative way, to draw the reader in and make it an enjoyable read while still being informative in all parts (there is no padding). In terms of science, the in-the-prose science is as minimal as possible to still convey what needs to be conveyed, while 25 pages of bibliography stack up at the end to show that indeed, this journalist cites sources.

    Bottom line: this is a really enjoyable book, packed with a wealth of knowledge, and is perfect to uplift your cooking by knowing your ingredients a little more intimately!

  • Hormones & Health, Beyond The Obvious

    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.

    Wholesome Health

    This is Dr. Sara Gottfried, who some decades ago got her MD from Harvard and specialized as an OB/GYN at MIT. She’s since then spent the more recent part of her career educating people (mostly: women) about hormonal health, precision, functional, & integrative medicine, and the importance of lifestyle medicine in general.

    What does she want us to know?

    Beyond “bikini zone health”

    Dr. Gottfried urges us to pay attention to our whole health, in context.

    “Women’s health” is often thought of as what lies beneath a bikini, and if it’s not in those places, then we can basically treat a woman like a man.

    And that’s often not actually true—because hormones affect every living cell in our body, and as a result, while prepubescent girls and postmenopausal women (specifically, those who are not on HRT) may share a few more similarities with boys and men of similar respective ages, for most people at most ages, men and women are by default quite different metabolically—which is what counts for a lot of diseases! And note, that difference is not just “faster” or “slower””, but is often very different in manner also.

    That’s why, even in cases where incidence of disease is approximately similar in men and women when other factors are controlled for (age, lifestyle, medical history, etc), the disease course and response to treatment may vary considerable. For a strong example of this, see for example:

    • The well-known: Heart Attack: His & Hers ← most people know these differences exist, but it’s always good to brush up on what they actually are
    • The less-known: Statins: His & Hers ← most people don’t know these differences exist, and it pays to know, especially if you are a woman or care about one

    Nor are brains exempt from his…

    The female brain (kinda)

    While the notion of an anatomically different brain for men and women has long since been thrown out as unscientific phrenology, and the idea of a genetically different brain is… Well, it’s an unreliable indicator, because technically the cells will have DNA and that DNA will usually (but not always; there are other options) have XX or XY chromosomes, which will usually (but again, not always) match apparent sex (in about 1/2000 cases there’s a mismatch, which is more common than, say, red hair; sometimes people find out about a chromosomal mismatch only later in life when getting a DNA test for some unrelated reason), and in any case, even for most of us, the chromosomal differences don’t count for much outside of antenatal development (telling the default genital materials which genitals to develop into, though this too can get diverted, per many intersex possibilities, which is also a lot more common than people think) or chromosome-specific conditions like colorblindness…

    The notion of a hormonally different brain is, in contrast to all of the above, a reliable and easily verifiable thing.

    See for example:

    Alzheimer’s Sex Differences May Not Be What They Appear

    Dr. Gottfried urges us to take the above seriously!

    Because, if women get Alzheimer’s much more commonly than men, and the disease progresses much more quickly in women than men, but that’s based on postmenopausal women not on HRT, then that’s saying “Women, without women’s usual hormones, don’t do so well as men with men’s usual hormones”.

    She does, by the way, advocate for bioidentical HRT for menopausal women, unless contraindicated for some important reason that your doctor/endocrinologist knows about. See also:

    Menopausal HRT: A Tale Of Two Approaches (Bioidentical vs Animal)

    The other very relevant hormone

    …that Dr. Gottfried wants us to pay attention to is insulin.

    Or rather, its scrubbing enzyme, the prosaically-named “insulin-degrading enzyme”, but it doesn’t only scrub insulin. It also scrubs amyloid beta—yes, the same that produces the amyloid beta plaques in the brain associated with Alzheimer’s. And, there’s only so much insulin-degrading enzyme to go around, and if it’s all busy breaking down excess insulin, there’s not enough left to do the other job too, and thus can’t break down amyloid beta.

    In other words: to fight neurodegeneration, keep your blood sugars healthy.

    This may actually work by multiple mechanisms besides the amyloid hypothesis, by the way:

  • Antioxidant Matcha Snack Bars

    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 antioxidants in this come not just from the matcha, but also the cacao nibs and chocolate, as well as lots of nutrients from the hazelnuts and cashews. If you’re allergic to nuts, we’ll give you substitutions that will change the nutritional profile (and flavor), but still work perfectly well and be healthy too.

    You will need

    For the base:

    • ⅔ cup roasted hazelnuts (if allergic, substitute dessicated coconut)
    • ⅔ cup chopped dates

    For the main part:

    • 1 cup raw cashews (if allergic, substitute raw coconut, chopped)
    • ½ cup almond milk (or your preferred milk of any kind)
    • ½ cup cacao nibs
    • 2 tbsp lime juice
    • 1 tbsp matcha powder
    • 1 tbsp maple syrup (omit if you don’t care for sweetness)

    For the topping (optional):

    • 2oz dark chocolate, melted (and if you like, tempered—but this isn’t necessary; it’ll just make it glossier if you do)
    • Spare cacao nibs, chopped nuts, or anything else you might want on there

    Method

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

    1) Blend the base ingredients in a food processor until it has a coarse sticky texture, but isn’t yet a paste or dough.

    2) Line a cake pan with baking paper and spread the base mix on the base; press it down to compact it a little and ensure it is flat. If there’s room, put this in the freezer while you do the next bit. If not, the fridge will suffice.

    3) Blend the main part ingredients apart from the cacao nibs, until smooth. Stir in the cacao nibs with a spoon.

    4) Spread the main part evenly over the base, and allow everything you’ve built (in this recipe, not in life in general) to chill in the fridge for at least 4 hours.

    5) Cut it into blocks of the size and shape you want to eat them, and (if adding the optional topping) separate the blocks slightly from each other, before drizzling with the chocolate topping. Put it back in the fridge to cool this too; an hour should be sufficient.

    6) Serve!

    Enjoy!

  • America’s Health System Isn’t Ready for the Surge of Seniors With Disabilities

    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 number of older adults with disabilities — difficulty with walking, seeing, hearing, memory, cognition, or performing daily tasks such as bathing or using the bathroom — will soar in the decades ahead, as baby boomers enter their 70s, 80s, and 90s.

    But the health care system isn’t ready to address their needs.

    That became painfully obvious during the covid-19 pandemic, when older adults with disabilities had trouble getting treatments and hundreds of thousands died. Now, the Department of Health and Human Services and the National Institutes of Health are targeting some failures that led to those problems.

    One initiative strengthens access to medical treatments, equipment, and web-based programs for people with disabilities. The other recognizes that people with disabilities, including older adults, are a separate population with special health concerns that need more research and attention.

    Lisa Iezzoni, 69, a professor at Harvard Medical School who has lived with multiple sclerosis since her early 20s and is widely considered the godmother of research on disability, called the developments “an important attempt to make health care more equitable for people with disabilities.”

    “For too long, medical providers have failed to address change in society, changes in technology, and changes in the kind of assistance that people need,” she said.

    Among Iezzoni’s notable findings published in recent years:

    Most doctors are biased. In survey results published in 2021, 82% of physicians admitted they believed people with significant disabilities have a worse quality of life than those without impairments. Only 57% said they welcomed disabled patients.

    “It’s shocking that so many physicians say they don’t want to care for these patients,” said Eric Campbell, a co-author of the study and professor of medicine at the University of Colorado.

    While the findings apply to disabled people of all ages, a larger proportion of older adults live with disabilities than younger age groups. About one-third of people 65 and older — nearly 19 million seniors — have a disability, according to the Institute on Disability at the University of New Hampshire.

    Doctors don’t understand their responsibilities. In 2022, Iezzoni, Campbell, and colleagues reported that 36% of physicians had little to no knowledge of their responsibilities under the 1990 Americans With Disabilities Act, indicating a concerning lack of training. The ADA requires medical practices to provide equal access to people with disabilities and accommodate disability-related needs.

    Among the practical consequences: Few clinics have height-adjustable tables or mechanical lifts that enable people who are frail or use wheelchairs to receive thorough medical examinations. Only a small number have scales to weigh patients in wheelchairs. And most diagnostic imaging equipment can’t be used by people with serious mobility limitations.

    Iezzoni has experienced these issues directly. She relies on a wheelchair and can’t transfer to a fixed-height exam table. She told me she hasn’t been weighed in years.

    Among the medical consequences: People with disabilities receive less preventive care and suffer from poorer health than other people, as well as more coexisting medical conditions. Physicians too often rely on incomplete information in making recommendations. There are more barriers to treatment and patients are less satisfied with the care they do get.

    Egregiously, during the pandemic, when crisis standards of care were developed, people with disabilities and older adults were deemed low priorities. These standards were meant to ration care, when necessary, given shortages of respirators and other potentially lifesaving interventions.

    There’s no starker example of the deleterious confluence of bias against seniors and people with disabilities. Unfortunately, older adults with disabilities routinely encounter these twinned types of discrimination when seeking medical care.

    Such discrimination would be explicitly banned under a rule proposed by HHS in September. For the first time in 50 years, it would update Section 504 of the Rehabilitation Act of 1973, a landmark statute that helped establish civil rights for people with disabilities.

    The new rule sets specific, enforceable standards for accessible equipment, including exam tables, scales, and diagnostic equipment. And it requires that electronic medical records, medical apps, and websites be made usable for people with various impairments and prohibits treatment policies based on stereotypes about people with disabilities, such as covid-era crisis standards of care.

    “This will make a really big difference to disabled people of all ages, especially older adults,” said Alison Barkoff, who heads the HHS Administration for Community Living. She expects the rule to be finalized this year, with provisions related to medical equipment going into effect in 2026. Medical providers will bear extra costs associated with compliance.

    Also in September, NIH designated people with disabilities as a population with health disparities that deserves further attention. This makes a new funding stream available and “should spur data collection that allows us to look with greater precision at the barriers and structural issues that have held people with disabilities back,” said Bonnielin Swenor, director of the Johns Hopkins University Disability Health Research Center.

    One important barrier for older adults: Unlike younger adults with disabilities, many seniors with impairments don’t identify themselves as disabled.

    “Before my mom died in October 2019, she became blind from macular degeneration and deaf from hereditary hearing loss. But she would never say she was disabled,” Iezzoni said.

    Similarly, older adults who can’t walk after a stroke or because of severe osteoarthritis generally think of themselves as having a medical condition, not a disability.

    Meanwhile, seniors haven’t been well integrated into the disability rights movement, which has been led by young and middle-aged adults. They typically don’t join disability-oriented communities that offer support from people with similar experiences. And they don’t ask for accommodations they might be entitled to under the ADA or the 1973 Rehabilitation Act.

    Many seniors don’t even realize they have rights under these laws, Swenor said. “We need to think more inclusively about people with disabilities and ensure that older adults are fully included at this really important moment of change.”

  • Which gut drugs might end up in a lawsuit? Are there really links with cancer and kidney disease? Should I stop taking them?

    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.

    Common medicines used to treat conditions including heartburn, reflux, indigestion and stomach ulcers may be the subject of a class action lawsuit in Australia.

    Lawyers are exploring whether long-term use of these over-the-counter and prescription drugs are linked to stomach cancer or kidney disease.

    The potential class action follows the settlement of a related multi-million dollar lawsuit in the United States. Last year, international pharmaceutical company AstraZeneca settled for US$425 million (A$637 million) after patients made the case that two of its drugs caused significant and potentially life-threatening side effects.

    Specifically, patients claimed the company’s drugs Nexium (esomeprazole) and Prilosec (omeprazole) increased the risk of kidney damage.

    Which drugs are involved in Australia?

    The class of drugs we’re talking about are “proton pump inhibitors” (sometimes called PPIs). In the case of the Australian potential class action, lawyers are investigating:

    • Nexium (esomeprazole)
    • Losec, Asimax (omeprazole)
    • Somac (pantoprazole)
    • Pariet (rabeprazole)
    • Zoton (lansoprazole).

    Depending on their strength and quantity, these medicines are available over-the-counter in pharmacies or by prescription.

    They have been available in Australia for more than 20 years and are in the top ten medicines dispensed through the Pharmaceutical Benefits Scheme.

    They are used to treat conditions exacerbated by stomach acid. These include heartburn, gastric reflux and indigestion. They work by blocking the protein responsible for pumping acid into the stomach.

    These drugs are also prescribed with antibiotics to treat the bacterium Helicobacter pylori, which causes stomach ulcers and stomach cancer.

    This class of drugs is also used with antibiotics to treat Helicobacter pylori infections. nobeastsofierce/Shutterstock

    What do we know about the risks?

    Appropriate use of proton pump inhibitors plays an important role in treating several serious digestive problems. Like all medicines, there are risks associated with their use depending on how much and how long they are used.

    When proton pump inhibitors are used appropriately for the short-term treatment of stomach problems, they are generally well tolerated, safe and effective.

    Their risks are mostly associated with long-term use (using them for more than a year) due to the negative effects from having reduced levels of stomach acid. In elderly people, these include an increased risk of gut and respiratory tract infections, nutrient deficiencies and fractures. Long-term use of these drugs in elderly people has also been associated with an increased risk of dementia.

    In children, there is an increased risk of serious infection associated with using these drugs, regardless of how long they are used.

    How about the cancer and kidney risk?

    Currently, the Australian consumer medicine information sheets that come with the medicines, like this one for esomeprazole, do not list stomach cancer or kidney injury as a risk associated with using proton pump inhibitors.

    So what does the evidence say about the risk?

    Over the past few years, there have been large studies based on observing people in the general population who have used proton pump inhibitors. These studies have found people who take them are almost two times more likely to develop stomach cancer and 1.7 times more likely to develop chronic kidney disease when compared with people who are not taking them.

    In particular, these studies report that users of the drugs lansoprazole and pantoprazole have about a three to four times higher risk than non-users of developing chronic kidney disease.

    While these observational studies show a link between using the drugs and these outcomes, we cannot say from this evidence that one causes the other.

    Researchers have not yet shown these drugs cause kidney disease. crystal light/Shutterstock

    What can I do if I’m worried?

    Several digestive conditions, especially reflux and heartburn, may benefit from simple dietary and lifestyle changes. But the overall evidence for these is not strong and how well they work varies between individuals.

    But it may help to avoid large meals within two to three hours before bed, and reduce your intake of fatty food, alcohol and coffee. Eating slowly and getting your weight down if you are overweight may also help your symptoms.

    There are also medications other than proton pump inhibitors that can be used for heartburn, reflux and stomach ulcers.

    These include over-the-counter antacids (such as Gaviscon and Mylanta), which work by neutralising the acidic environment of the stomach.

    Alternatives for prescription drugs include nizatidine and famotidine. These work by blocking histamine receptors in the stomach, which decreases stomach acid production.

    If you are concerned about your use of proton pump inhibitors it is important to speak with your doctor or pharmacist before you stop using them. That’s because when you have been using them for a while, stopping them may result in increased or “rebound” acid production.
