The title of this book is a little misleading, as it’s not really about biohacking; it’s more like a care and maintenance manual for the brain.
This distinction is relevant, because to hack a thing is to use it in a way it’s not supposed to be used, and/or get it to do something it’s not supposed to do.
Intead, what neurobiologist Dr. Kristen Willeumier offers us is much more important: how to keep our brain in good condition.
She takes us through the various things that our brain needs, and what will happen if it doesn’t get them. Some are dietary, some are behavioral, some are even cognitive.
A strength of this book is not just explaining what things are good for the brain, but also: why. Understanding the “why” can be the motivational factor that makes a difference between us doing the thing or not!
For example, if we know that exercise is good for the brain, we think “sounds reasonable” and carry on with what we were doing. If, however, we also understand how increased bloodflow helps with the timely removal of beta-amyloids that are associated with Alzheimer’s, we’re more likely to make time for getting that movement going.
Bottom line: there are key things we can do to keep our brain healthy, and you probably wouldn’t want to miss any. This book is a great care manual for such!

In Defense of Food – by Michael Pollan
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 more like the French. Or the Italians. Or the Japanese. Or…
Somehow, whatever we eat is not good enough, and we should always be doing it differently!
Michael Pollan takes a more down-to-Earth approach.
He kicks off by questioning the wisdom of thinking of our food only in terms of nutritional profiles, and overthinking healthy-eating. He concludes, as many do, that a “common-sense, moderate” approach is needed.
And yet, most people who believe they are taking a “common-sense, moderate” approach to health are in fact over-fed yet under-nourished.
So, how to fix this?
He offers us a reframe: to think of food as a relationship, and health being a product of it:
- If we are constantly stressing about a relationship, it’s probably not good.
- On the other hand, if we are completely thoughtless about it, it’s probably not good either.
- But if we can outline some good, basic principles and celebrate it with a whole heart? It’s probably at the very least decent.
The style is very casual and readable throughout. His conclusions, by the way, can be summed up as “Eat real food, make it mostly plants, and make it not too much”.
However, to summarize it thusly undercuts a lot of the actual value of the book, which is the principles for discerning what is “real food” and what is “not too much”.
Bottom line: if you’re tired of complicated eating plans, this book can help produce something very simple, attainable, and really quite good.

Coughing/Wheezing After Dinner?
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 After-Dinner Activities You Don’t Want
A quick note first: our usual medical/legal disclaimer applies here, and we are not here to diagnose you or treat you; we are not doctors, let alone your doctors. Do see yours if you have any reason to believe there may be cause for concern.
Coughing and/or wheezing after eating is more common the younger or older someone is. Lest that seem contradictory: it’s a U-shaped bell-curve.
It can happen at any age and for any of a number of reasons, but there are patterns to the distribution:
Mostly affects younger people:
Allergies, asthma
Young people are less likely to have a body that’s fully adapted to all foods yet, and asthma can be triggered by certain foods (for example sulfites, a common preservative additive):
Adverse reactions to the sulphite additives
Foods/drinks that commonly contain sulfites include soft drinks, wines and beers, and dried fruit
As for the allergies side of things, you probably know the usual list of allergens to watch out for, e.g: dairy, fish, crustaceans, eggs, soy, wheat, nuts.
However, that’s far from an exhaustive list, so it’s good to see an allergist if you suspect it may be an allergic reaction.
Affects young and old people equally:
Again, there’s a dip in the middle where this doesn’t tend to affect younger adults so much, but for young and old people:
Dysphagia (difficulty swallowing)
For children, this can be a case of not having fully got used to eating yet if very small, and when growing, can be a case of “this body is constantly changing and that makes things difficult”.
For older people, this can can come from a variety of reasons, but common culprits include neurological disorders (including stroke and/or dementia), or a change in saliva quality and quantity—a side-effect of many medications:
Hyposalivation in Elderly Patients
(particularly useful in the article above is the table of drugs that are associated with this problem, and the various ways they may affect it)
Managing this may be different depending on what is causing your dysphagia (as it could be anything from antidepressants to cancer), so this is definitely one to see your doctor about. For some pointers, though:
NHS Inform | Dysphagia (swallowing problems)
Affects older people more:
Gastroesophagal reflux disease (GERD)
This is a kind of acid reflux, but chronic, and often with a slightly different set of symptoms.
GERD has no known cure once established, but its symptoms can be managed (or avoided in the first place) by:
- Healthy eating (Mediterranean diet is, as usual, great)
- Weight loss (if and only if obese)
- Avoiding trigger foods
- Eating smaller meals
- Practicing mindful eating
- Staying upright for 3–4 hours after eating
And of course, don’t smoke, and ideally don’t drink alcohol.
You can read more about this (and the different ways it can go from there), here:
NICE | Gastro-oesophageal reflux disease
Note: this above page refers to it as “GORD”, because of the British English spelling of “oesophagus” rather than “esophagus”. It’s the exact same organ and condition, just a different spelling.

Food and exercise can treat depression as well as a psychologist, our study found. And it’s cheaper
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.
Around 3.2 million Australians live with depression.
At the same time, few Australians meet recommended dietary or physical activity guidelines. What has one got to do with the other?
Our world-first trial, published this week, shows improving diet and doing more physical activity can be as effective as therapy with a psychologist for treating low-grade depression.
Previous studies (including our own) have found “lifestyle” therapies are effective for depression. But they have never been directly compared with psychological therapies – until now.
Amid a nation-wide shortage of mental health professionals, our research points to a potential solution. As we found lifestyle counselling was as effective as psychological therapy, our findings suggest dietitians and exercise physiologists may one day play a role in managing depression.
What did our study measure?
During the prolonged COVID lockdowns, Victorians’ distress levels were high and widespread. Face-to-face mental health services were limited.
Our trial targeted people living in Victoria with elevated distress, meaning at least mild depression but not necessarily a diagnosed mental disorder. Typical symptoms included feeling down, hopeless, irritable or tearful.
We partnered with our local mental health service to recruit 182 adults and provided group-based sessions on Zoom. All participants took part in up to six sessions over eight weeks, facilitated by health professionals.
Half were randomly assigned to participate in a program co-facilitated by an accredited practising dietitian and an exercise physiologist. That group – called the lifestyle program – developed nutrition and movement goals:
- eating a wide variety of foods
- choosing high-fibre plant foods
- including high quality fats
- limiting discretionary foods, such as those high in saturated fats and added sugars
- doing enjoyable physical activity.
The second group took part in psychotherapy sessions convened by two psychologists. The psychotherapy program used cognitive behavioural therapy (CBT), the gold standard for treating depression in groups and when delivered remotely.
In both groups, participants could continue existing treatments (such as taking antidepressant medication). We gave both groups workbooks and hampers. The lifestyle group received a food hamper, while the psychotherapy group received items such as a colouring book, stress ball and head massager.
Lifestyle therapies just as effective
We found similar results in each program.
At the trial’s beginning we gave each participant a score based on their self-reported mental health. We measured them again at the end of the program.
Over eight weeks, those scores showed symptoms of depression reduced for participants in the lifestyle program (42%) and the psychotherapy program (37%). That difference was not statistically or clinically meaningful so we could conclude both treatments were as good as each other.
There were some differences between groups. People in the lifestyle program improved their diet, while those in the psychotherapy program felt they had increased their social support – meaning how connected they felt to other people – compared to at the start of the treatment.
Participants in both programs increased their physical activity. While this was expected for those in the lifestyle program, it was less expected for those in the psychotherapy program. It may be because they knew they were enrolled in a research study about lifestyle and subconsciously changed their activity patterns, or it could be a positive by-product of doing psychotherapy.
There was also not much difference in cost. The lifestyle program was slightly cheaper to deliver: A$482 per participant, versus $503 for psychotherapy. That’s because hourly rates differ between dietitians and exercise physiologists, and psychologists.
What does this mean for mental health workforce shortages?
Demand for mental health services is increasing in Australia, while at the same time the workforce faces worsening nation-wide shortages.
Psychologists, who provide about half of all mental health services, can have long wait times. Our results suggest that, with the appropriate training and guidelines, allied health professionals who specialise in diet and exercise could help address this gap.
Lifestyle therapies can be combined with psychology sessions for multi-disciplinary care. But diet and exercise therapies could prove particularly effective for those on waitlists to see a psychologists, who may be receiving no other professional support while they wait.
Many dietitians and exercise physiologists already have advanced skills and expertise in motivating behaviour change. Most accredited practising dietitians are trained in managing eating disorders or gastrointestinal conditions, which commonly overlap with depression.
There is also a cost argument. It is overall cheaper to train a dietitian ($153,039) than a psychologist ($189,063) – and it takes less time.
Potential barriers
Australians with chronic conditions (such as diabetes) can access subsidised dietitian and exercise physiologist appointments under various Medicare treatment plans. Those with eating disorders can also access subsidised dietitian appointments. But mental health care plans for people with depression do not support subsidised sessions with dietitians or exercise physiologists, despite peak bodies urging them to do so.
Increased training, upskilling and Medicare subsidies would be needed to support dietitians and exercise physiologists to be involved in treating mental health issues.
Our training and clinical guidelines are intended to help clinicians practising lifestyle-based mental health care within their scope of practice (activities a health care provider can undertake).
Future directions
Our trial took place during COVID lockdowns and examined people with at least mild symptoms of depression who did not necessarily have a mental disorder. We are seeking to replicate these findings and are now running a study open to Australians with mental health conditions such as major depression or bipolar disorder.

Burned Out By Tuesday?
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.
Avoiding Burnout, The Active Way
This is Dr. Claudine Holt. She’s double board-certified, in Occupational & Environmental Medicine, and Lifestyle Medicine.
In short: preventative medicine in all parts of our life.
Hopefully, you are reading this bright-eyed and bushy-tailed and ready to take on another exciting day in this wonderful, beautiful world!
On the other hand, it’s possible that you’re reading this semi-focussed, looking for a crumb of dopamine as much as you are looking for information.
If you’ve ever had the “What a week!” / “It’s only Tuesday” moment, this one’s for you.
What does Dr. Holt want us to know?
You can recover from burnout without guilt
Sometimes, we overreach ourselves. Sometimes, life overreaches us! Sometimes it’s not that we overcommitted—it’s just that we were taking each day as it comes, but sometimes several days gang up on us at once.
Sometimes, even, we can feel exhausted when it seems like we haven’t done anything.
Note: if you feel exhausted and it seems like you haven’t done anything, then be aware: you are exhausted for a reason!
What that reason might be may vary, but contrary to popular belief, energy does not just vanish. It went somewhere.
This goes double if you have any chronic illness(es), even if you’re not aware of having had a flare-up, chances are you were just exceptionally busy (on a cellular level).
And it’s easy to think that “mere” cellular activity shouldn’t be exhausting, but that is 100% of where our energy transactions happen—whether or not we are consciously aware of them!
See also: Eat To Beat Chronic Fatigue ← yes, this also covers when you are too exhausted to shop and cook like a TV chef
Dr. Holt specializes in working with burned out medical professionals (and also specifically specializes in working with women), but there are lessons for everyone in her advice. For example:
Fiction: ”Medicine is my calling–it’s who I am.”
Fact: You are more than medicine! Remember that your career is just one aspect of your life. Don’t forget to create your big-picture vision and tend the garden of the other areas of your life too.
Read more: Dr. Claudine Holt | Burnout: Fact vs Fiction
This same thing can go for whatever part of your identity frequently follows “I’m a…”, and is somewhere that you put a lot of your energy; it could equally be a non-professional job like “homemaker”, or a relational status like “husband”, or a cultural identifier like “Christian”, or a hobby like “gardener” (assuming that is not also your profession, in which case, same item, different category).
Indeed, a lot of women especially get hit by “the triple burden” of professional work, housework, and childcare. And it’s not even necessarily that we resent any of those things or feel like they’re a burden; we (hopefully) love our professions, homes, children. But, here’s the thing:
No amount of love will add extra hours to the day.
So what does she recommend doing about it, when sometimes we’re juggling things that can’t be dropped?
Start simple, but start!
Dr. Holt recommends to start with a smile (yes even if, and sometimes especially when, the circumstances do not feel like they merit it), and deploy some CBT tools:
Two Hacks to Quickly Rise Above Burnout (Or Any Circumstance)
We’ve expanded on this topic here:
With a more level head on, it becomes easier to take on the next step, which creating healthy boundaries—and that doesn’t just mean with other people!
It also means slaying our own perfectionism and imposter syndrome—both things that will have us chasing our tails 36 hours per day if we let them.
See also:
❝Burnout is the culture of our times. A culture that expects us to do more and think our way out of everything. A culture that asks for more than the body can bear. Unfortunately, even though the situation might not be of our creation, burnout culture is our inheritance.
An inheritance we can either perpetuate—or change—depending on what we embody.❞
Source: The Embodied MD on Burnout with Dr Claudine Holt
That “embodiment” is partly our choices and actions that we bring and own just as we bring and own our body—and it’s partly our relationship with our body itself, and learning to love it, and work with it to achieve wonderful things, instead of just getting through the day.
Which yes, does also mean making space for good diet, exercise, sleep and so forth, per:

DVT Risk Management Beyond The Socks
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 know I am at higher risk of DVT after having hip surgery, any advice beside compression stockings?❞
First of all, a swift and easy recovery to you!
Surgery indeed increases the risk of deep vein thrombosis (henceforth: DVT), and hip or knee surgery especially so, for obvious reasons.
There are other risk factors you can’t control, like genetics (family history of DVT as an indicator) and age, but there are some that you can, including:
- smoking (so, ideally don’t; do speak to your doctor before quitting though, in case withdrawal might be temporarily worse for you than smoking)
- obesity (so, losing weight is good if overweight, but if this is going to happen, it’ll mostly happen in the kitchen not the gym, which may be a relief as you’re probably not the very most up for exercise at present)
- See also: Lose Weight, But Healthily
- sedentariness (so, while you’re probably not running marathons right now, please do try to keep moving, even if only gently)
Beyond that, yes compression socks, but also frequent gentle massage can help a lot to avoid clots forming.
Also, no surprises, a healthy diet will help, especially one that’s good for general heart health. Check out for example the Mediterranean DASH diet:
Four Ways To Upgrade The Mediterranean Diet
Also, obviously, speak with your doctor/pharmacist if you haven’t already about possible medications, including checking whether any of your current medications increase the risk and could be swapped for something that doesn’t.
Take care!

Forget Ringing the Button for the Nurse. Patients Now Stay Connected by Wearing One.
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.
HOUSTON — Patients admitted to Houston Methodist Hospital get a monitoring device about the size of a half-dollar affixed to their chest — and an unwitting role in the expanding use of artificial intelligence in health care.
The slender, battery-powered gadget, called a BioButton, records vital signs including heart and breathing rates, then wirelessly sends the readings to nurses sitting in a 24-hour control room elsewhere in the hospital or in their homes. The device’s software uses AI to analyze the voluminous data and detect signs a patient’s condition is deteriorating.
Hospital officials say the BioButton has improved care and reduced the workload of bedside nurses since its rollout last year.
“Because we catch things earlier, patients are doing better, as we don’t have to wait for the bedside team to notice if something is going wrong,” said Sarah Pletcher, system vice president at Houston Methodist.
But some nurses fear the technology could wind up replacing them rather than supporting them — and harming patients. Houston Methodist, one of dozens of U.S. hospitals to employ the device, is the first to use the BioButton to monitor all patients except those in intensive care, Pletcher said.
“The hype around a lot of these devices is they provide care at scale for less labor costs,” said Michelle Mahon, a registered nurse and an assistant director of National Nurses United, the profession’s largest U.S. union. “This is a trend that we find disturbing,” she said.
The rollout of BioButton is among the latest examples of hospitals deploying technology to improve efficiency and address a decades-old nursing shortage. But that transition has raised its own concerns, including about the device’s use of AI; polls show the public is wary of health providers relying on it for patient care.
In December 2022 the FDA cleared the BioButton for use in adult patients who are not in critical care. It is one of many AI tools now used by hospitals for tasks like reading diagnostic imaging results.
In 2023, President Joe Biden directed the Department of Health and Human Services to develop a plan to regulate AI in hospitals, including by collecting reports of patients harmed by its use.
The leader of BioIntelliSense, which developed the BioButton, said its device is a huge advance compared with nurses walking into a room every few hours to measure vital signs. “With AI, you now move from ‘I wonder why this patient crashed’ to ‘I can see this crash coming before it happens and intervene appropriately,’” said James Mault, CEO of the Golden, Colorado-based company.
The BioButton stays on the skin with an adhesive, is waterproof, and has up to a 30-day battery life. The company says the device — which allows providers to quickly notice deteriorating health by recording more than 1,000 measurements a day per patient — has been used on more than 80,000 hospital patients nationwide in the past year.
Hospitals pay BioIntelliSense an annual subscription fee for the devices and software.
Houston Methodist officials would not reveal how much the hospital pays for the technology, though Pletcher said it equates to less than a cup of coffee a day per patient.
For a hospital system that treats thousands of patients at a time — Houston Methodist has 2,653 non-ICU beds at its eight Houston-area hospitals — such an investment could still translate to millions of dollars a year.
Hospital officials say they have not made any changes in nurse staffing and have no plans to because of implementing the BioButton.
Inside the hospital’s control center for virtual monitoring on a recent morning, about 15 nurses and technicians dressed in scrubs sat in front of large monitors showing the health status of hundreds of patients they were assigned to monitor.
A red checkmark next to a patient’s name signaled the AI software had found readings trending outside normal. Staff members could click into a patient’s medical record, showing patients’ vital signs over time and other medical history. These virtual nurses, if you will, could contact nurses on the floor by phone or email, or even dial directly into the patient’s room via video call.
Nutanben Gandhi, a technician who was watching 446 patients on her monitor that morning, said that when she gets an alert, she looks at the patient’s health record to see if the anomaly can be easily explained by something in the patient’s condition or if she needs to contact nurses on the patient’s floor.
Oftentimes an alert can be easily dismissed. But identifying signs of deteriorating health can be tough, said Steve Klahn, Houston Methodist’s clinical director of virtual medicine.
“We are looking for a needle in a haystack,” he said.
Donald Eustes, 65, was admitted to Houston Methodist in March for prostate cancer treatment and has since been treated for a stroke. He is happy to wear the BioButton.
“You never know what can happen here, and having an extra set of eyes looking at you is a good thing,” he said from his hospital bed. After being told the device uses AI, the Montgomery, Texas, man said he has no problem with its helping his clinical team. “This sounds like a good use of artificial intelligence.”
Patients and nurses alike benefit from remote monitoring like the BioButton, said Pletcher of Houston Methodist.
The hospital has placed small cameras and microphones inside all patient rooms enabling nurses outside to communicate with patients and perform tasks such as helping with patient admissions and discharge instructions. Patients can include family members on the remote calls with nurses or a doctor, she said.
Virtual technology frees up on-duty nurses to provide more hands-on help, such as starting an intravenous line, Pletcher said. With the BioButton, nurses can wait to take routine vital signs every eight hours instead of every four, she said.
Pletcher said the device reduces nurses’ stress in monitoring patients and allows some to work more flexible hours because virtual care can be done from home rather than coming to the hospital. Ultimately it helps retain nurses, not drive them away, she said.
Sheeba Roy, a nurse manager at Houston Methodist, said some members of the nursing staff were nervous about relying on the device and not checking patients’ vital signs as often themselves. But testing has shown the device provides accurate information.
“After we implemented it, the staff loves it,” Roy said.
Serena Bumpus, chief executive officer of the Texas Nurses Association, said her concern with any technology is that it can be more burdensome on nurses and take away time with patients.
“We have to be hypervigilant in ensuring that we are not leaning on this to replace the ability of nurses to critically think and assess patients and validate what this device is telling us is true,” Bumpus said.
Houston Methodist this year plans to send the BioButton home with patients so the hospital can better track their progress in the weeks after discharge, measuring the quality of their sleep and checking their gait.
“We are not going to need less nurses in health care, but we have limited resources and we have to use those as thoughtfully as we can,” Pletcher said. “Looking at projected demand and seeing the supply we have coming, we will not have enough to meet demand, so anything we can do to give time back to nurses is a good thing.”
