Metabolical – by Dr. Robert Lustig

The premise of this book itself is not novel: processed food is bad, food giants lie to us, and eating better makes us less prone to disease (especially metabolic disease).
What this book does offer that’s less commonly found is a comprehensive guide, a walkthrough of each relevant what and why and how, with plenty of good science and practical real-world examples.
In terms of unique selling points, perhaps the greatest strength of this book is its focus on two things in particular that affect many aspects of health: looking after our liver, and looking after our gut.
The style is… A little dramatic perhaps, but that’s just the style; there’s no hyperbole, he is stating well-established scientific facts.
Bottom line: very much of chronic disease would be a lot less diseasey if we all ate with these aspects of our health in mind. This book’s a comprehensive guide to that.

Lifespan – by Dr. David Sinclair
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Some books on longevity are science-heavy and heavy-going; others are glorified manifestos with much philosophy but little practical.
This one’s a sciencey-book written for a lay reader. It’s heavily referenced, but not a challenging read.
This book is divided into three parts:
- What we know (the past)
- What we’re learning (the present)
- Where we’re going (the future)
Let us quickly mention: the last part is principally sociology and economics, which are not the author’s wheelhouse. Some readers may enjoy his thoughts regardless, but we’re going to concentrate on where we found the real value of the book to be: in the first and second parts, where he brings his expertise to bear.
The first part lays the foundational knowledge that’s critical for understanding why the second part is so important.
Basically: aging is a genetic disease, and diseases can be cured. No disease has magical properties, even if sometimes it can seem for a while like they do, until we understand them better.
The second part covers a lot of recent and contemporary research into aging. We learn about such things as NAD-agonists that make elderly mice biologically young again, and the Greenland shark that easily lives for 500 years or so (currently the record-holder for vertebrates). And of course, biologically immortal jellyfish.
It’s not all animal studies though…
We learn of how NAD-agonists such as NMN have been promising in human studies too, along with resveratrol and the humble diabetes drug, metformin. These things alone may have the power to extend healthy life by 20%
Other recommendations pertain to lifestyle; the usual five things (diet, exercise, sleep, no alcohol, no smoking), as well as intermittent fasting and cryotherapy (cold showers/baths).
Bottom line: this book is informative and inspiring, and if you’ve been looking for an “in” to understanding the world of biogerontology and/or anti-aging research, this is it.

When Age Is A Flexible Number

Aging, Counterclockwise!
In the late 1970s, Dr. Ellen Langer hypothesized that physical markers of aging could be affected by psychosomatic means.
Note: psychosomatic does not mean “it’s all in your head”.
Psychosomatic means “your body does what your brain tells it to do, for better or for worse”
She set about testing that, in what has been referred to since as…
The Counterclockwise Study
A small (n=16) sample of men in their late 70s and early 80s were recruited in what they were told was a study about reminiscing.
Back in the 1970s, it was still standard practice in the field of psychology to outright lie to participants (who in those days were called “subjects”), so this slight obfuscation was a much smaller ethical aberration than in some famous studies of the same era and earlier (cough cough Zimbardo cough Milgram cough).
Anyway, the participants were treated to a week in a 1950s-themed retreat, specifically 1959, a date twenty years prior to the experiment’s date in 1979. The environment was decorated and furnished authentically to the date, down to the food and the available magazines and TV/radio shows; period-typical clothing was also provided, and so forth.
- The control group were told to spend the time reminiscing about 1959
- The experimental group were told to pretend (and maintain the pretense, for the duration) that it really was 1959
The results? On many measures of aging, the experimental group participants became quantifiably younger:
❝The experimental group showed greater improvement in joint flexibility, finger length (their arthritis diminished and they were able to straighten their fingers more), and manual dexterity.
On intelligence tests, 63 percent of the experimental group improved their scores, compared with only 44 percent of the control group. There were also improvements in height, weight, gait, and posture.
Finally, we asked people unaware of the study’s purpose to compare photos taken of the participants at the end of the week with those submitted at the beginning of the study. These objective observers judged that all of the experimental participants looked noticeably younger at the end of the study.❞
Remember, this was after one week.
Her famous study was completed in 1979, and/but not published until eleven years later in 1990, with the innocuous title:
Higher stages of human development: Perspectives on adult growth
You can read about it much more accessibly, and in much more detail, in her book:
Counterclockwise: A Proven Way to Think Yourself Younger and Healthier – by Dr. Ellen Langer
We haven’t reviewed that particular book yet, so here’s Linda Graham’s review, that noted:
❝Langer cites other research that has made similar findings.
In one study, for instance, 650 people were surveyed about their attitudes on aging. Twenty years later, those with a positive attitude with regard to aging had lived seven years longer on average than those with a negative attitude to aging.
(By comparison, researchers estimate that we extend our lives by four years if we lower our blood pressure and reduce our cholesterol.)
In another study, participants read a list of negative words about aging; within 15 minutes, they were walking more slowly than they had before.❞
Read the review in full:
Aging in Reverse: A Review of Counterclockwise
The Counterclockwise study has been repeated since, and/but we are still waiting for the latest (exciting, much larger sample, 90 participants this time) study to be published. The research proposal describes the method in great detail, and you can read that with one click over on PubMed:
It was approved, and has now been completed (as of 2020), but the results have not been published yet; you can see the timeline of how that’s progressing over on ClinicalTrials.gov:
Clinical Trials | Ageing as a Mindset: A Counterclockwise Experiment to Rejuvenate Older Adults
Hopefully it’ll take less time than the eleven years it took for the original study, but in the meantime, there seems to be nothing to lose in doing a little “Citizen Science” for ourselves.
Maybe a week in a 20 years-ago themed resort (writer’s note: wow, that would only be 2004; that doesn’t feel right; it should surely be at least the 90s!) isn’t a viable option for you, but we’re willing to bet it’s possible to “microdose” on this method. Given that the original study lasted only a week, even just a themed date-night on a regular recurring basis seems like a great option to explore (if you’re not partnered then well, indulge yourself how best you see fit, in accord with the same premise; a date-night can be with yourself too!).
Just remember the most important take-away though:
Don’t accidentally put yourself in your own control group!
In other words, it’s critically important that for the duration of the exercise, you act and even think as though it is the appropriate date.
If you instead spend your time thinking “wow, I miss the [decade that does it for you]”, you will dodge the benefits, and potentially even make yourself feel (and thus, potentially, if the inverse hypothesis holds true, become) older.
This latter is not just our hypothesis by the way, there is an established potential for nocebo effect.
For example, the following study looked at how instructions given in clinical tests can be worded in a way that make people feel differently about their age, and impact the results of the mental and/or physical tests then administered:
❝Our results seem to suggest how manipulations by instructions appeared to be more largely used and capable of producing more clear performance variations on cognitive, memory, and physical tasks.
Age-related stereotypes showed potentially stronger effects when they are negative, implicit, and temporally closer to the test of performance. ❞
(and yes, that’s the same Dr. Francesco Pagnini whose name you saw atop the other study we cited above, with the 90 participants recreating the Counterclockwise study)

How to Fall Asleep Faster: CBT-Insomnia Treatment
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.
Insomnia affects a lot of people, and is even more common as we get older. Happily, therapist Emma McAdam is here with a drug-free solution that will work for most people most of the time.
Cognitive Behavioral Therapy for Insomnia (CBTI)
While people think of causes of insomnia as being things such as stress, anxiety, overthinking, disturbances, and so forth, these things affect sleep in the short term, but don’t directly cause chronic insomnia.
We say “directly”, because chronic insomnia is usually the result of the brain becoming accustomed to the above, and thus accidentally training itself to not sleep.
The remedy: cut the bad habit of staying in bed while awake. Lying in bed awake trains the brain to associate lying in bed with wakefulness (and any associated worrying, etc). In essence, we lie down, and the brain thinks “Aha, we know this one; this is the time and place for worrying, ok, let’s get to work”.
So instead: if you’re in bed and not asleep within 15 minutes, get up and do something non-stimulating until you feel sleepy, then return to bed. This may cause some short term tiredness, but it will usually correct the chronic insomnia within a week.

Heart Health vs Systemic Stress
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.
At The Heart Of Good Health
This is Dr. Michelle Albert. She’s a cardiologist with a decades-long impressive career, recently including a term as the president of the American Heart Association. She’s the current Admissions Dean at UCSF Medical School. She’s accumulated enough awards and honors that if we list them, this email will not fit in your inbox without getting clipped.
What does she want us to know?
First, lifestyle
Although Dr. Albert is also known for her work with statins (which found that pravastatin may have anti-inflammatory effects in addition to lipid-lowering effects, which is especially good news for women, for whom the lipid-lowering effects may be less useful than for men), she is keen to emphasize that they should not be anyone’s first port-of-call unless “first” here means “didn’t see the risk until it was too late and now LDL levels are already ≥190 mg/dL”.
Instead, she recommends taking seriously the guidelines on:
- getting plenty of fruit, vegetables, whole grains, lean protein
- avoiding red meat, processed meats, refined carbohydrates, and sweetened beverages
- getting your 150 minutes per week of moderate exercise
- avoiding alcohol, and definitely abstaining from smoking

Next, get your house in order
No, not your home gym—though sure, that too!
But rather: after the “Top Five Things” we linked just above, the sixth on the list would be “reduce stress”. Indeed, as Dr. Albert says:
❝Heart health is not just about the physical heart but also about emotional well-being. Stress management is crucial for a healthy heart❞
~ Dr. Michelle Albert
This is where a lot of people would advise mindfulness meditation, CBT, somatic therapies, and the like. And these things are useful! See for example:
No-Frills, Evidence-Based Mindfulness
…and:
However, Dr. Albert also advocates for awareness of what some professionals have called “Shit Life Syndrome”.
This is more about socioeconomic factors. There are many of those that can’t be controlled by the individual, for example:
❝Adverse maternal experiences such as depression, economic issues and low social status can lead to poor cognitive outcomes as well as cardiovascular disease.
Many jarring statistics illuminate a marked wealth gap by race and ethnicity… You might be thinking education could help bridge that gap. But it is not that simple.
While education does increase wealth, the returns are not the same for everyone. Black persons need a post-graduate degree just to attain similar wealth as white individuals with a high school degree.❞
~ Dr. Michelle Albert
Read in full: AHA president: The connection between economic adversity and cardiovascular health
What this means in practical terms (besides advocating for structural change to tackle the things such as the racism that has been baked into a lot of systems for generations) is:
Be aware not just of your obvious health risk factors, but also your socioeconomic risk factors, if you want to have good general health outcomes.
So for example, let’s say that you, dear reader, are wealthy and white, in which case you have some very big things in your favor, but are you also a woman? Because if so…
Women and Minorities Bear the Brunt of Medical Misdiagnosis
See also, relevant for some: Obesity Discrimination In Healthcare Settings ← you’ll need to scroll to the penultimate section for this one.
In other words… If you are one of the majority of people who is a woman and/or some kind of minority, things are already stacked against you, and not only will this have its own direct harmful effect, but also, it’s going to make your life harder and that stress increases CVD risk more than salt.
In short…
This means: tackle not just your stress, but also the things that cause that. Look after your finances, gather social support, know your rights and be prepared to self-advocate / have someone advocate for you, and go into medical appointments with calm well-prepared confidence.
Take care!

Hazelnuts vs Pecans – 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 hazelnuts to pecans, we picked the hazelnuts.
Why?
In terms of macros, hazelnuts have more protein, carbs, and fiber, though the difference is not big in the latter two cases, and the glycemic indices are resultantly about the same. Meanwhile, pecans have a little more fat, but the fat is healthy in both cases. Everything taken into account, we’re calling it a tie on macros.
When it comes to vitamins, hazelnuts have more of vitamins B3, B5, B6, B7, B9, C, E, K, and choline, while pecans have more of vitamins A, B1, and B2. An easy win for hazelnuts here.
In the category of minerals, hazelnuts have more calcium, copper, iron, magnesium, manganese, phosphorus, and potassium, while pecans have more selenium and zinc. Another clear win for hazelnuts.
In short, enjoy either or both (unless you’re allergic, in which case, don’t), but hazelnuts are ultimately the more nutritionally dense of the two.

In Vermont, Where Almost Everyone Has Insurance, Many Can’t Find or Afford Care
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.
RICHMOND, Vt. — On a warm autumn morning, Roger Brown walked through a grove of towering trees whose sap fuels his maple syrup business. He was checking for damage after recent flooding. But these days, his workers’ health worries him more than his trees’.
The cost of Slopeside Syrup’s employee health insurance premiums spiked 24% this year. Next year it will rise 14%.
The jumps mean less money to pay workers, and expensive insurance coverage that doesn’t ensure employees can get care, Brown said. “Vermont is seen as the most progressive state, so how is health care here so screwed up?”
Vermont consistently ranks among the healthiest states, and its unemployment and uninsured rates are among the lowest. Yet Vermonters pay the highest prices nationwide for individual health coverage, and state reports show its providers and insurers are in financial trouble. Nine of the state’s 14 hospitals are losing money, and the state’s largest insurer is struggling to remain solvent. Long waits for care have become increasingly common, according to state reports and interviews with residents and industry officials.
Rising health costs are a problem across the country, but Vermont’s situation surprises health experts because virtually all its residents have insurance and the state regulates care and coverage prices.
For more than 15 years, federal and state policymakers have focused on increasing the number of people insured, which they expected would shore up hospital finances and make care more available and affordable.
“Vermont’s struggles are a wake-up call that insurance is only one piece of the puzzle to ensuring access to care,” said Keith Mueller, a rural health expert at the University of Iowa.
Regulators and consultants say the state’s small, aging population of about 650,000 makes spreading insurance risk difficult. That demographic challenge is compounded by geography, as many Vermonters live in rural areas, where it’s difficult to attract more health workers to address shortages.
At least part of the cost spike can be attributed to patients crossing state lines for quicker care in New York and Massachusetts. Those visits can be more expensive for both insurers and patients because of long ambulance rides and charges from out-of-network providers.
Patients who stay, like Lynne Drevik, face long waits. Drevik said her doctor told her in April that she needed knee replacement surgeries — but the earliest appointment would be in January for one knee and the following April for the other.
Drevik, 59, said it hurts to climb the stairs in the 19th-century farmhouse in Montgomery Center she and her husband operate as an inn and a spa. “My life is on hold here, and it’s hard to make any plans,” she said. “It’s terrible.”
Health experts say some of the state’s health system troubles are self-inflicted.
Unlike most states, Vermont regulates hospital and insurance prices through an independent agency, the Green Mountain Care Board. Until recently, the board typically approved whatever price changes companies wanted, said Julie Wasserman, a health consultant in Vermont.
The board allowed one health system — the University of Vermont Health Network — to control about two-thirds of the state’s hospital market and allowed its main facility, the University of Vermont Medical Center in Burlington, to raise its prices until it ranked among the nation’s most expensive, she said, citing data the board presented in September.
Hospital officials contend their prices are no higher than industry averages.
But for 2025, the board required the University of Vermont Medical Center to cut the prices it bills private insurers by 1%.
The nonprofit system says it is navigating its own challenges. Top officials say a severe lack of housing makes it hard to recruit workers, while too few mental health providers, nursing homes, and long-term care services often create delays in discharging patients, adding to costs.
Two-thirds of the system’s patients are covered by Medicare or Medicaid, said CEO Sunny Eappen. Both government programs pay providers lower rates than private insurance, which Eappen said makes it difficult to afford rising prices for drugs, medical devices, and labor.
Officials at the University of Vermont Medical Center point to several ways they are trying to adapt. They cited, for example, $9 million the hospital system has contributed to the construction of two large apartment buildings to house new workers, at a subsidized price for lower-income employees.
The hospital also has worked with community partners to open a mental health urgent care center, providing an alternative to the emergency room.
In the ER, curtains separate areas in the hallway where patients can lie on beds or gurneys for hours waiting for a room. The hospital also uses what was a storage closet as an overflow room to provide care.
“It’s good to get patients into a hallway, as it’s better than a chair,” said Mariah McNamara, an ER doctor and associate chief medical officer with the hospital.
For the about 250 days a year when the hospital is full, doctors face pressure to discharge patients without the ideal home or community care setup, she said. “We have to go in the direction of letting you go home without patient services and giving that a try, because otherwise the hospital is going to be full of people, and that includes people that don’t need to be here,” McNamara said.
Searching for solutions, the Green Mountain Care Board hired a consultant who recommended a number of changes, including converting four rural hospitals into outpatient facilities, in a worst-case scenario, and consolidating specialty services at several others.
The consultant, Bruce Hamory, said in a call with reporters that his report provides a road map for Vermont, where “the health care system is no match for demographic, workforce, and housing challenges.”
But he cautioned that any fix would require sacrifice from everyone, including patients, employers, and health providers. “There is no simple single policy solution,” he said.
One place Hamory recommended converting to an outpatient center only was North Country Hospital in Newport, a village in Vermont’s least populated region, known as the Northeast Kingdom.
The 25-bed hospital has lost money for years, partly because of an electronic health record system that has made it difficult to bill patients. But the hospital also has struggled to attract providers and make enough money to pay them.
Officials said they would fight any plans to close the hospital, which recently dropped several specialty services, including pulmonology, neurology, urology, and orthopedics. It doesn’t have the cash to upgrade patient rooms to include bathroom doors wide enough for wheelchairs.
On a recent morning, CEO Tom Frank walked the halls of his hospital. The facility was quiet, with just 14 admitted patients and only a couple of people in the ER. “This place used to be bustling,” he said of the former pulmonology clinic.
Frank said the hospital breaks even treating Medicare patients, loses money treating Medicaid patients, and makes money from a dwindling number of privately insured patients.
The state’s strict regulations have earned it an antihousing, antibusiness reputation, he said. “The cost of health care is a symptom of a larger problem.”
About 30 miles south of Newport, Andy Kehler often worries about the cost of providing health insurance to the 85 workers at Jasper Hill Farm, the cheesemaking business he co-owns.
“It’s an issue every year for us, and it looks like there is no end in sight,” he said.
Jasper Hill pays half the cost of its workers’ health insurance premiums because that’s all it can afford, Kehler said. Employees pay $1,700 a month for a family, with a $5,000 deductible.
“The coverage we provide is inadequate for what you pay,” he said.
