There are lots of books on “happy chemicals” and “how to retrain your brain”, so what makes this one different?

Firstly, it focuses on four “happy chemicals”, not just one:

  • Serotonin
  • Dopamine
  • Oxytocin
  • Endorphins

It also looks at the role of cortisol, and how it caps off each of those just a little bit, to keep us just a little malcontent.

Behavioral psychology tends to focus most on dopamine, while prescription pharmaceuticals for happiness (i.e., most antidepressants) tend to focus on serotonin. Here, Dr. Breuning helps us understand the complex interplay of all of the aforementioned chemicals.

She also clears up many misconceptions, since a lot of people misattribute the functions of each of these.

Common examples include “I’m doing this for the serotonin!” when the activity is dopaminergic not serotoninergic, or considering dopamine “the love molecule” when oxytocin, or even something else like phenylethylamine would be more appropriate.

The above may seem like academic quibbles and not something of practical use, but if we want to biohack our brains, we need to do better than the equivalent of a chef who doesn’t know the difference between salt and sugar.

Where things are of less practical use, she tends to skip over or at least streamline them. For example, she doesn’t really discuss the role of post-dopamine prolactin in men—but the discussion of post-happiness cortisol covers the same ground anyway, for practical purposes.

Dr. Breuning also looks at where our evolved neurochemical responses go wrong, and lays out guidelines for such challenges as overcoming addiction, or embracing delayed gratification.

Bottom line: this book is a great user-manual for the brain. If you’d like to be happier and more effective with fewer bad habits, this is the book for you.

  • The Wim Hof Method – by Wim Hof

    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.

    In Wednesday’s main feature, we wrote about the Wim Hof Method, and/but only scratched the surface. Such is the downside of being a super-condensed newsletter! However, it does give us the opportunity to feature the book:

    The Wim Hof Method is definitely loudly trumpeted as “up there” with Atomic Habits or How Not To Die in the category of “life-changing” books. Why?

    Firstly, it’s a very motivational book. Hof is a big proponent of the notion “if you think you can or you think you can’t, you’re right” idea, practises what he preaches, and makes clear he’s not special.

    Secondly, it’s backed up with science. While it’s not a science-heavy book and that’s not the main focus, there are references to studies. Where physiological explanations are given for how certain things work, those explanations are sound. There’s no pseudoscience here, which is especially important for a book of this genre!

    What does the book have that our article didn’t? A good few things:

    • More about Hof’s own background and where it’s taken him. This is generally not a reason people buy books (unless they are biographies), but it’s interesting nonetheless.
    • A lot more advice, data, and information about Cold Therapy and how it can (and, he argues convincingly, should) be built into your life.
    • A lot about breathing exercises that we just didn’t cover at all in our article, but is actually an important part of the Wim Hof Method.
    • More about stepping through the psychological barriers that can hold us back.

    Bottom line: this book offers benefits that stretch into many areas of life, from some simple habits that can be built.

    Falafel is a wonderful snack or accompaniment to a main, and if you’ve only had shop-bought, you’re missing out. Plus, with this quinoa-based recipe, it’s almost impossible to accidentally make them dry.

    You will need

    • 1 cup cooked quinoa
    • 1 cup chopped fresh parsley
    • ½ cup wholewheat breadcrumbs (or rye breadcrumbs if you’re avoiding wheat/gluten)
    • 1 can chickpeas, drained
    • 4 green onions, chopped
    • ½ bulb garlic, minced
    • 2 tbsp extra virgin olive oil, plus more for frying
    • 2 tbsp tomato paste

    • 1 tsp red pepper flakes
    • 1 tsp black pepper, coarse ground
    • 1 tsp dried thyme
    • ½ tsp MSG or 1 tsp low-sodium salt

    Method

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

    1) Blend all the ingredients in a food processor until it has an even, but still moderately coarse, texture.

    2) Shape into 1″ balls, and put them in the fridge to chill for about 20 minutes.

    3) Fry the balls over a medium-high heat until evenly browned—just do a few at a time, taking care to not overcrowd the pan.

    4) Serve! Great with salad, hummus, and other such tasty healthy snack items:

    Enjoy!

  • With all this bird flu around, how safe are eggs, chicken or milk?

    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.

    Enzo Palombo, Swinburne University of Technology

    Recent outbreaks of bird flu – in US dairy herds, poultry farms in Australia and elsewhere, and isolated cases in humans – have raised the issue of food safety.

    So can the virus transfer from infected farm animals to contaminate milk, meat or eggs? How likely is this?

    And what do we need to think about to minimise our risk when shopping for or preparing food?

    AS Foodstudio/Shutterstock

    How safe is milk?

    Bird flu (or avian influenza) is a bird disease caused by specific types of influenza virus. But the virus can also infect cows. In the US, for instance, to date more than 80 dairy herds in at least nine states have been infected with the H5N1 version of the virus.

    Investigations are under way to confirm how this happened. But we do know infected birds can shed the virus in their saliva, nasal secretions and faeces. So bird flu can potentially contaminate animal-derived food products during processing and manufacturing.

    Indeed, fragments of bird flu genetic material (RNA) were found in cow’s milk from the dairy herds associated with infected US farmers.

    However, the spread of bird flu among cattle, and possibly to humans, is likely to have been caused through contact with contaminated milking equipment, not the milk itself.

    The test used to detect the virus in milk – which uses similar PCR technology to lab-based COVID tests – is also highly sensitive. This means it can detect very low levels of the bird flu RNA. But the test does not distinguish between live or inactivated virus, just that the RNA is present. So from this test alone, we cannot tell if the virus found in milk is infectious (and capable of infecting humans).

    Does that mean milk is safe to drink and won’t transmit bird flu? Yes and no.

    In Australia, where bird flu has not been reported in dairy cattle, the answer is yes. It is safe to drink milk and milk products made from Australian milk.

    In the US, the answer depends on whether the milk is pasteurised. We know pasteurisation is a common and reliable method of destroying concerning microbes, including influenza virus. Like most viruses, influenza virus (including bird flu virus) is inactivated by heat.

    Although there is little direct research on whether pasteurisation inactivates H5N1 in milk, we can extrapolate from what we know about heat inactivation of H5N1 in chicken and eggs.

    So we can be confident there is no risk of bird flu transmission via pasteurised milk or milk products.

    However, it’s another matter for unpasteurised or “raw” US milk or milk products. A recent study showed mice fed raw milk contaminated with bird flu developed signs of illness. So to be on the safe side, it would be advisable to avoid raw milk products.

    How about chicken?

    Bird flu has caused sporadic outbreaks in wild birds and domestic poultry worldwide, including in Australia. In recent weeks, there have been three reported outbreaks in Victorian poultry farms (two with H7N3 bird flu, one with H7N9). There has been one reported outbreak in Western Australia (H9N2).

    The strains of bird flu identified in the Victorian and Western Australia outbreaks can cause human infection, although these are rare and typically result from close contact with infected live birds or contaminated environments.

    Therefore, the chance of bird flu transmission in chicken meat is remote.

    Nonetheless, it is timely to remind people to handle chicken meat with caution as many dangerous pathogens, such as Salmonella and Campylobacter, can be found on chicken carcasses.

    Always handle chicken meat carefully when shopping, transporting it home and storing it in the kitchen. For instance, make sure no meat juices cross-contaminate other items, consider using a cool bag when transporting meat, and refrigerate or freeze the meat within two hours.

    Avoid washing your chicken before cooking to prevent the spread of disease-causing microbes around the kitchen.

    Finally, cook chicken thoroughly as viruses (including bird flu) cannot survive cooking temperatures.

    Are eggs safe?

    The recent Australian outbreaks have occurred in egg-laying or mixed poultry flocks, so concerns have been raised about bird flu transmission via contaminated chicken eggs.

    Can flu viruses contaminate chicken eggs and potentially spread bird flu? It appears so. A report from 2007 said it was feasible for influenza viruses to enter through the eggshell. This is because influenza virus particles are smaller (100 nanometres) than the pores in eggshells (at least 200 nm).

    So viruses could enter eggs and be protected from cleaning procedures designed to remove microbes from the egg surface.

    Therefore, like the advice about milk and meat, cooking eggs is best.

    The US Food and Drug Administration recommends cooking poultry, eggs and other animal products to the proper temperature and preventing cross-contamination between raw and cooked food.

    In a nutshell

    If you consume pasteurised milk products and thoroughly cook your chicken and eggs, there is nothing to worry about as bird flu is inactivated by heat.

    The real fear is that the virus will evolve into highly pathogenic versions that can be transmitted from human to human.

    That scenario is much more frightening than any potential spread though food.

  • Do We Simply Not Care About Old People?

    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 covid-19 pandemic would be a wake-up call for America, advocates for the elderly predicted: incontrovertible proof that the nation wasn’t doing enough to care for vulnerable older adults.

    The death toll was shocking, as were reports of chaos in nursing homes and seniors suffering from isolation, depression, untreated illness, and neglect. Around 900,000 older adults have died of covid-19 to date, accounting for 3 of every 4 Americans who have perished in the pandemic.

    But decisive actions that advocates had hoped for haven’t materialized. Today, most people — and government officials — appear to accept covid as a part of ordinary life. Many seniors at high risk aren’t getting antiviral therapies for covid, and most older adults in nursing homes aren’t getting updated vaccines. Efforts to strengthen care quality in nursing homes and assisted living centers have stalled amid debate over costs and the availability of staff. And only a small percentage of people are masking or taking other precautions in public despite a new wave of covid, flu, and respiratory syncytial virus infections hospitalizing and killing seniors.

    In the last week of 2023 and the first two weeks of 2024 alone, 4,810 people 65 and older lost their lives to covid — a group that would fill more than 10 large airliners — according to data provided by the CDC. But the alarm that would attend plane crashes is notably absent. (During the same period, the flu killed an additional 1,201 seniors, and RSV killed 126.)

    “It boggles my mind that there isn’t more outrage,” said Alice Bonner, 66, senior adviser for aging at the Institute for Healthcare Improvement. “I’m at the point where I want to say, ‘What the heck? Why aren’t people responding and doing more for older adults?’”

    It’s a good question. Do we simply not care?

    I put this big-picture question, which rarely gets asked amid debates over budgets and policies, to health care professionals, researchers, and policymakers who are older themselves and have spent many years working in the aging field. Here are some of their responses.

    The pandemic made things worse. Prejudice against older adults is nothing new, but “it feels more intense, more hostile” now than previously, said Karl Pillemer, 69, a professor of psychology and gerontology at Cornell University.

    “I think the pandemic helped reinforce images of older people as sick, frail, and isolated — as people who aren’t like the rest of us,” he said. “And human nature being what it is, we tend to like people who are similar to us and be less well disposed to ‘the others.’”

    “A lot of us felt isolated and threatened during the pandemic. It made us sit there and think, ‘What I really care about is protecting myself, my wife, my brother, my kids, and screw everybody else,’” said W. Andrew Achenbaum, 76, the author of nine books on aging and a professor emeritus at Texas Medical Center in Houston.

    In an environment of “us against them,” where everybody wants to blame somebody, Achenbaum continued, “who’s expendable? Older people who aren’t seen as productive, who consume resources believed to be in short supply. It’s really hard to give old people their due when you’re terrified about your own existence.”

    Although covid continues to circulate, disproportionately affecting older adults, “people now think the crisis is over, and we have a deep desire to return to normal,” said Edwin Walker, 67, who leads the Administration on Aging at the Department of Health and Human Services. He spoke as an individual, not a government representative.

    The upshot is “we didn’t learn the lessons we should have,” and the ageism that surfaced during the pandemic hasn’t abated, he observed.

    Ageism is pervasive. “Everyone loves their own parents. But as a society, we don’t value older adults or the people who care for them,” said Robert Kramer, 74, co-founder and strategic adviser at the National Investment Center for Seniors Housing & Care.

    Kramer thinks boomers are reaping what they have sown. “We have chased youth and glorified youth. When you spend billions of dollars trying to stay young, look young, act young, you build in an automatic fear and prejudice of the opposite.”

    Combine the fear of diminishment, decline, and death that can accompany growing older with the trauma and fear that arose during the pandemic, and “I think covid has pushed us back in whatever progress we were making in addressing the needs of our rapidly aging society. It has further stigmatized aging,” said John Rowe, 79, professor of health policy and aging at Columbia University’s Mailman School of Public Health.

    “The message to older adults is: ‘Your time has passed, give up your seat at the table, stop consuming resources, fall in line,’” said Anne Montgomery, 65, a health policy expert at the National Committee to Preserve Social Security and Medicare. She believes, however, that baby boomers can “rewrite and flip that script if we want to and if we work to change systems that embody the values of a deeply ageist society.”

    Integration, not separation, is needed. The best way to overcome stigma is “to get to know the people you are stigmatizing,” said G. Allen Power, 70, a geriatrician and the chair in aging and dementia innovation at the Schlegel-University of Waterloo Research Institute for Aging in Canada. “But we separate ourselves from older people so we don’t have to think about our own aging and our own mortality.”

    The solution: “We have to find ways to better integrate older adults in the community as opposed to moving them to campuses where they are apart from the rest of us,” Power said. “We need to stop seeing older people only through the lens of what services they might need and think instead of all they have to offer society.”

    That point is a core precept of the National Academy of Medicine’s 2022 report Global Roadmap for Healthy Longevity. Older people are a “natural resource” who “make substantial contributions to their families and communities,” the report’s authors write in introducing their findings.

    Those contributions include financial support to families, caregiving assistance, volunteering, and ongoing participation in the workforce, among other things.

    “When older people thrive, all people thrive,” the report concludes.

    Future generations will get their turn. That’s a message Kramer conveys in classes he teaches at the University of Southern California, Cornell, and other institutions. “You have far more at stake in changing the way we approach aging than I do,” he tells his students. “You are far more likely, statistically, to live past 100 than I am. If you don’t change society’s attitudes about aging, you will be condemned to lead the last third of your life in social, economic, and cultural irrelevance.”

    As for himself and the baby boom generation, Kramer thinks it’s “too late” to effect the meaningful changes he hopes the future will bring.

    “I suspect things for people in my generation could get a lot worse in the years ahead,” Pillemer said. “People are greatly underestimating what the cost of caring for the older population is going to be over the next 10 to 20 years, and I think that’s going to cause increased conflict.”

  • Functional Exercise For Seniors – by James Atkinson

    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 lot of exercises books are tailored to 20-year-old athletes training for their first Tough Mudder. Others, that the only thing standing between us and a perfect Retroflex Countersupine Divine Pretzel position is a professionally-lit Instagrammable photo.

    This one’s not like that.

    But! Nor does it think being over a certain age is a reason to not have genuinely robust health, of the kind that may make some younger people envious. So, it lays out, in progressive format, guidelines for exercises targeted at everything we need to build and maintain as we get older.

    The writing style is clear, and the illustrations too (the cover art is the same style as the illustrations inside).

    Bottom line: if you’re looking for a workout guide that understands you are nearer 80 than 18, and/but also doesn’t assume your age limits your exercise potential to “wrist exercises in chair”, then this book is a fine pick.

  • Sesame & Peanut Tofu

    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.

    Yesterday we learned how to elevate tofu from “nutrition” to “nutritious tasty snack” with our Basic Baked Tofu recipe; today we’re expanding on that, to take it from “nutritious tasty snack” to “very respectable meal”.

    You will need

    For the tofu:

    • The Basic Baked Tofu that we made yesterday (consider making this to be “step zero” of today’s recipe if you don’t already have a portion in the fridge)

    For the sauce:

    • ⅓ cup peanut butter, ideally with no added sugar or salt (if allergic to peanuts specifically, use almond butter; if allergic to nuts generally, use tahini)
    • ¼ bulb garlic, grated or crushed
    • 1 tbsp tamarind paste
    • 1½ tbsp tamari sauce (or low-sodium soy sauce, if a substitution is necessary)
    • 1 tbsp sambal oelek (or sriracha sauce, if a substitution is necessary)
    • 1 tsp ground coriander
    • 1 tsp ground black pepper
    • ½ tsp ground sweet cinnamon
    • ½ tsp MSG (or else omit; do not substitute with salt in this case unless you have a particular craving)
    • zest of 1 lime

    For the vegetables:

    • 14 oz broccolini / tenderstem broccoli, thick ends trimmed (failing that, any broccoli)
    • 6 oz shelled edamame
    • 1½ tsp toasted sesame oil

    For serving:

    • 4 cups cooked rice (we recommend our Tasty Versatile Rice recipe)
    • ½ cup raw cashews, soaked in hot water for at least 5 minutes and then drained (if allergic, substitute cooked chickpeas, rinsed and drained)
    • 1 tbsp toasted sesame seeds
    • 1 handful chopped cilantro, unless you have the “this tastes like soap” gene, in which case substitute chopped parsley

    Method

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

    1) Combine the sauce ingredients in a bowl and whisk well (or use a blender if you have one that’s comfortable with this relatively small quantity of ingredients). Taste it, and adjust the ingredient ratios if you’d like more saltiness, sweetness, sourness, spiciness, umami.

    2) Prepare a bowl with cold water and some ice. Steam the broccolini and edamame for about 3 minutes; as soon as they become tender, dump them into the ice bathe to halt the cooking process. Let them chill for a few minutes, then drain, dry, and toss in the sesame oil.

    3) Reheat the tofu if necessary (an air fryer is great for this), and then combine with half of the sauce in a bowl, tossing gently to coat well.

    4) Add a little extra water to the remaining sauce, enough to make it pourable, whisking to an even consistency.

    5) Assemble; do it per your preference, but we recommend the order: rice, vegetables, tofu, cashews, sauce, sesame seeds, herbs.

    Enjoy!
