Eat beans & greens, take walks, have a purpose; you can probably list off the top of your head some of the “advices from Blue Zones”, so what makes this book stand out?

This is perhaps one of the most thoughtful investigations; the author (a National Geographic researcher) toured and researched all the Blue Zones, took many many notes (we get details), and asked a lot of questions that others skipped.

For example, a lot of books about the Blue Zones mention the importance of community—but they don’t go into much detail of what that looks like… And they certainly don’t tend to explain what we should do about it.

And that’s because community is often viewed as environmental in a way that we can’t control. If we want to take supplements, eat a certain way, exercise, etc, we can do all those things alone if we want. But if we want community? We’re reliant on other people—and that’s a taboo in the US, and US-influenced places.

So, one way this book excels is in describing how exactly people foster community in the Blue Zones (hint: the big picture—the form of the community—is different in each place, but the individual actions taken are similar), with particular attention to the roles actively taken on by the community elders.

In a similar vein, “reduce stress” is good, but what mindsets and mechanisms do they use that are still reproducible if we are not, for example, Okinawan farmers? Again, Buettner delivers in spades.

Bottom line: this is the Blue Zones book that digs deeper than others, and makes the advices much more applicable no matter where we live.

  • One More Resource Against Osteoporosis!

    Your Bones Were Made For Moving Too!

    We know that to look after bone health, resistance training is generally what’s indicated. Indeed, we mentioned it yesterday, and we’ve talked about it before:

    Resistance Is Useful! (Especially As We Get Older)

    We also know that if you have osteoporosis already, some exercises are a better or worse idea than others:

    Osteoporosis & Exercises: Which To Do (And Which To Avoid)

    However! New research suggests that also getting in your recommended 150 minutes per week of moderate exercise slows bone density loss.

    The study by Dr. Tiina Savikangas et al. looked at 299 people in their 70s (just over half being women) and found that, over the course of a year, bone mineral density loss was inversely correlated with moderate exercise as recorded by an accelerometer (as found in most fitness-tracking wearables and smartphones).

    In other words: those who got more minutes of exercise, kept more bone mineral density.

    As well as monitoring bone mineral density, the study also looked at cross-sectional area, but that remained stable throughout.

    As for how much is needed:

    ❝Even short bursts of activity can be significant for the skeleton, so we also looked at movement in terms of the number and intensity of individual impacts. For example, walking and running cause impacts of different intensities.

    We found that impacts that were comparable to at least brisk walking were associated with better preservation of bone mineral density.❞

    ~ Dr. Tiina Savikangas

    On which note, we’ve a small bone to pick…

    As a small correction, the pop-science source says that the subjects’ ages ranged from 70 to 85 years; the paper, meanwhile, clearly shows that the age-range was 74.4±3.9 years (shown in the “Results” table), rounded to 74.4 ± 4 years, in the abstract. So, certainly no participant was older than 78 years and four months.

    Why this matters: the age range itself may be critical or it might not, but what is important is that this highlights how we shouldn’t just believe figures cited in pop-science articles, and it’s always good to click through to the source!

    Read the study: Changes in femoral neck bone mineral density and structural strength during a 12-month multicomponent exercise intervention among older adults – Does accelerometer-measured physical activity matter?

    This paper is a particularly fascinating read if you have time, because—unlike a lot of studies—they really took great care to note what exactly can and cannot be inferred from the data, and how and why.

    Especially noteworthy was the diligence with which they either controlled for, or recognized that they could not control for, far more variables than most studies even bother to mention.

    This kind of transparency is critical for good science, and we’d love to see more of it!

  • How community health screenings get more people of color vaccinated

    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.

    U.S. preventive health screening rates dropped drastically at the height of the COVID-19 pandemic. They have yet to go back to pre-pandemic levels, especially for Black and Latine communities

    Screenings, or routine medical checkups, are important ways to avoid and treat disease. They’re key to finding problems early on and can even help save people’s lives. 

    Community health workers say screenings are also a key to getting more people vaccinated. Screening fairs provide health workers the chance to build rapport and trust with the communities they serve, while giving their clients the chance to ask questions and get personalized recommendations according to their age, gender, and family history.

    But systemic barriers to health care can often keep people from marginalized communities from accessing recommended screenings, exacerbating racial health disparities. 

    Public Good News spoke with Dr. Marie-Jose Francois, president and chief executive officer, and April Johnson, outreach coordinator, at the Center for Multicultural Wellness and Prevention (CMWP), in Central Florida, to learn how they promote the benefits of screening and leverage screenings for vaccination outreach among their diverse communities. 

    Here’s what they said. 

    [Editor’s note: This content has been edited for clarity and length.]

    PGN: What is CMWP’s mission? How does vaccine outreach fit into the work you do in the communities you serve?

    Dr. Marie-Jose Francois: Since 1995, our mission has been to enhance the health, wellness, and quality of life for diverse populations in Central Florida. At the beginning, our main focus was education, wellness, and screening for HIV/AIDS, and we continue to do case management for HIV screening and testing. 

    When the issue of COVID-19 came into the picture, we included COVID-19 information and education and stressed the importance of screening and receiving vaccinations during all of our outreach activities. 

    We try to meet the community where they are. Because there is so much misconception—and taboo—in regard to immunization. 

    April Johnson: So our job is to disperse accurate information. And how we do that is we go into rural communities. We build partnerships with local apartment complexes, hair salons, nail salons, laundromats, and provide a little community engagement, where people just hang out in different areas. 

    We build gatekeepers in those communities because you first have to get in there. You have to know that they trust you. Being in this field for about 30 years, I’ve [learned that] flexibility is key. Because sometimes you can’t get them from 9 to 5, or [from] Monday through Friday. So, you have to be very flexible in doing the outreach portion in order to get what you need. 

    I’ve built collaborations with senior citizen centers, community centers, schools, clinics, churches in Orlando and [in] different areas in Orange, Osceola, Seminole, and Lake counties. And we also partner with other community-based organizations to try to make it like a one-stop shop. So, partnership is a big thing. 

    PGN: How do you promote the importance of preventive screenings in the communities you serve?

    M.F.: We try to make them view their health in a more comprehensive way, for them to understand the importance of screening. [That] self care is key, and for them to not be afraid. 

    We empower them to know what to ask when they go to the doctor. We ask them, ‘Do you know your status? Do you know your numbers?’ 

    For example, if you go to the doctor, do you know your blood pressure? If you’re diabetic? Do you know your hemoglobin (A1C)? Do you know your cholesterol levels

    And now, [we also ask them]: ‘Have you received your flu shot for the year? Have you received all of your vaccine doses for COVID-19?’ We are even adding the mpox vaccine now, based on risk factors. 

    [We recommend they] ask their provider. For women, [we ask], ‘When do you need to have your mammogram?’ For the men, ‘You need to ask about your PSA and also about when and when to have your colonoscopy based on your age.’ 

    We also try to explain to the community that the more they know their family history, the more they can engage in their own health. Because sometimes you have mom and dad who have a history of cancer. They have a history of diabetes or blood pressure—and they don’t talk to their children. So, we try to [recommend they] talk to their children. Your own family needs to know what’s going on so they can be proactive in their screenings.

    PGN: What strategies or methods have you found most effective in getting people screened? 

    M.F.: Not everybody wants to be screened, not everybody wants to receive vaccines. 

    But with patience, just give them the facts. It goes right back to education, people have to be assured. 

    When you talk to them about COVID, or even HIV, you may hear them say, ‘Oh, I don’t see myself at risk for HIV.’  But we have to repeat to them that the more they get screened to make sure they’re OK, the better it is for them. ‘The more you use condoms, [the] safer it is for you.’ 

    In Haitian culture, they listen to the radio. So we use the radio as a tool to educate and deliver information [to] get vaccinated, wash your hands. ‘If you’re coughing, cover your mouth. If you have a fever, wear your masks. Call your doctor.’ 

    In our target population, we have people who have chronic conditions. We have people with HIV. So, we have to motivate them to receive the flu vaccine, to receive the COVID vaccine, to receive that RSV [vaccine], or to get the mpox vaccine. We have people with diabetes, high blood pressure, high cholesterol, depressed immune systems. We have people with lupus, we have people with sickle cell disease. 

    So, this is a way to [ensure that] whomever you’re talking to one-on-one understands the value of being safe.

  • Macadamia Nuts vs Brazil Nuts – 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 macadamia nuts to Brazil nuts, we picked the Brazil nuts.

    Why?

    They’re a lot more nutrient dense! But watch out…

    First, to do due diligence in terms of macros: Brazil nuts have twice as much protein and less fat, as well as being a little higher in fiber and slightly lower in carbs.

    In terms of vitamins, Brazil nuts are about 10x higher in vitamin E, while macadamias are somewhat higher in several B-vitamins.

    The category of minerals is where it gets interesting. Macadamia nuts are a little higher in iron and considerably higher in Manganese. But… Brazil nuts are a lot higher in calcium, copper, magnesium, phosphorus, potassium, selenium, and zinc.

    About that selenium… Specifically, it’s more than 5,000x higher, and a cup of Brazil nuts would give nearly 10,000x the recommended daily amount of selenium. Now, selenium is an essential mineral (needed for thyroid hormone production, for example), and at the RDA it’s good for good health. Your hair will be luscious and shiny. However, go much above that, and selenium toxicity becomes a thing, you may get sick, and it can cause your (luscious and shiny) hair to fall out. For this reason, it’s recommended to eat no more than 3–4 Brazil nuts per day.

    In short… Brazil nuts are much more nutrient dense in general, and thus come out on top here. But, they’re so nutrient dense in the case of selenium, that careful moderation is advised.

  • Exercises for Sciatica Pain Relief

    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.

    Jessica Valant is a physiotherapist and Pilates teacher, and today she’s going to demonstrate some exercise that relieve (and also correct the cause of) sciatica pain.

    Back to good health

    You will need a large strap for one of these exercises; a Pilates strap is great, but you can also use a towel. The exercises are:

    Pelvic Rocking Exercise:

    • Lie on your back, feet flat, knees bent.
    • Gently rock your pelvis forwards and backwards (50% effort, no glute squeezing).

    Leg Stretch with Strap:

    • Straighten your left leg and loop the strap around the ball of your right foot.
    • Gently straighten and bend your right leg while holding the strap.
    • Perform a “nerve glide” by flexing and pointing your foot (not a stretch, just gentle movement).
    • Repeat on the left leg.

    Piriformis Stretch:

    • Bend your right knee and place your left ankle over it (figure-four position).
    • For a deeper stretch, hold your right thigh and pull your legs inwards.

    Lower Back Release:

    • Let your legs fall gently to one side after stretching each leg, opening the lower back.

    Back Extension:

    • Lie on your belly, placing your elbows down, palms flat.
    • Optional: push up slightly into a back bend if it feels comfortable.

    Seated Stretching:

    • Finish by sitting cross-legged or on a chair.
    • Inhale while raising your arms up, exhale while lowering them down, then reach sideways with your arms to stretch.
    • Perform gentle neck stretches by tilting your ear to your shoulder on each side.

    She recommends doing these exercises daily for at least a few weeks, though you should start to see improvement in your symptoms immediately. Nothing here should cause a problem or make things worse, but if it does, stop immediately and consult a local physiotherapist for more personalized advice.

  • Is stress turning my hair grey?

    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.

    When we start to go grey depends a lot on genetics.

    Your first grey hairs usually appear anywhere between your twenties and fifties. For men, grey hairs normally start at the temples and sideburns. Women tend to start greying on the hairline, especially at the front.

    The most rapid greying usually happens between ages 50 and 60. But does anything we do speed up the process? And is there anything we can do to slow it down?

    You’ve probably heard that plucking, dyeing and stress can make your hair go grey – and that redheads don’t. Here’s what the science says.

    Oksana Klymenko/Shutterstock

    What gives hair its colour?

    Each strand of hair is produced by a hair follicle, a tunnel-like opening in your skin. Follicles contain two different kinds of stem cells:

    • keratinocytes, which produce keratin, the protein that makes and regenerates hair strands
    • melanocytes, which produce melanin, the pigment that colours your hair and skin.

    There are two main types of melanin that determine hair colour. Eumelanin is a black-brown pigment and pheomelanin is a red-yellow pigment.

    The amount of the different pigments determines hair colour. Black and brown hair has mostly eumelanin, red hair has the most pheomelanin, and blonde hair has just a small amount of both.

    So what makes our hair turn grey?

    As we age, it’s normal for cells to become less active. In the hair follicle, this means stem cells produce less melanin – turning our hair grey – and less keratin, causing hair thinning and loss.

    As less melanin is produced, there is less pigment to give the hair its colour. Grey hair has very little melanin, while white hair has none left.

    Unpigmented hair looks grey, white or silver because light reflects off the keratin, which is pale yellow.

    Grey hair is thicker, coarser and stiffer than hair with pigment. This is because the shape of the hair follicle becomes irregular as the stem cells change with age.

    Interestingly, grey hair also grows faster than pigmented hair, but it uses more energy in the process.

    Can stress turn our hair grey?

    Yes, stress can cause your hair to turn grey. This happens when oxidative stress damages hair follicles and stem cells and stops them producing melanin.

    Oxidative stress is an imbalance of too many damaging free radical chemicals and not enough protective antioxidant chemicals in the body. It can be caused by psychological or emotional stress as well as autoimmune diseases.

    Environmental factors such as exposure to UV and pollution, as well as smoking and some drugs, can also play a role.

    Melanocytes are more susceptible to damage than keratinocytes because of the complex steps in melanin production. This explains why ageing and stress usually cause hair greying before hair loss.

    Scientists have been able to link less pigmented sections of a hair strand to stressful events in a person’s life. In younger people, whose stems cells still produced melanin, colour returned to the hair after the stressful event passed.

    4 popular ideas about grey hair – and what science says

    1. Does plucking a grey hair make more grow back in its place?

    No. When you pluck a hair, you might notice a small bulb at the end that was attached to your scalp. This is the root. It grows from the hair follicle.

    Plucking a hair pulls the root out of the follicle. But the follicle itself is the opening in your skin and can’t be plucked out. Each hair follicle can only grow a single hair.

    It’s possible frequent plucking could make your hair grey earlier, if the cells that produce melanin are damaged or exhausted from too much regrowth.

    2. Can my hair can turn grey overnight?

    Legend says Marie Antoinette’s hair went completely white the night before the French queen faced the guillotine – but this is a myth.

    Painted portrait of Marie Antoinette with elaborate grey hairstyle.
    It is not possible for hair to turn grey overnight, as in the legend about Marie Antoinette. Yann Caradec/Wikimedia, CC BY-NC-SA

    Melanin in hair strands is chemically stable, meaning it can’t transform instantly.

    Acute psychological stress does rapidly deplete melanocyte stem cells in mice. But the effect doesn’t show up immediately. Instead, grey hair becomes visible as the strand grows – at a rate of about 1 cm per month.

    Not all hair is in the growing phase at any one time, meaning it can’t all go grey at the same time.

    3. Will dyeing make my hair go grey faster?

    This depends on the dye.

    Temporary and semi-permanent dyes should not cause early greying because they just coat the hair strand without changing its structure. But permanent products cause a chemical reaction with the hair, using an oxidising agent such as hydrogen peroxide.

    Accumulation of hydrogen peroxide and other hair dye chemicals in the hair follicle can damage melanocytes and keratinocytes, which can cause greying and hair loss.

    4. Is it true redheads don’t go grey?

    People with red hair also lose melanin as they age, but differently to those with black or brown hair.

    This is because the red-yellow and black-brown pigments are chemically different.

    Producing the brown-black pigment eumelanin is more complex and takes more energy, making it more susceptible to damage.

    Producing the red-yellow pigment (pheomelanin) causes less oxidative stress, and is more simple. This means it is easier for stem cells to continue to produce pheomelanin, even as they reduce their activity with ageing.

    With ageing, red hair tends to fade into strawberry blonde and silvery-white. Grey colour is due to less eumelanin activity, so is more common in those with black and brown hair.

    Your genetics determine when you’ll start going grey. But you may be able to avoid premature greying by staying healthy, reducing stress and avoiding smoking, too much alcohol and UV exposure.

    Eating a healthy diet may also help because vitamin B12, copper, iron, calcium and zinc all influence melanin production and hair pigmentation.
