Why You Can’t Skimp On Amino Acids

Our body requires 20 amino acids (the building blocks of protein), 9 of which it can’t synthesize (thus called: “essential”) and absolutely must get from food. Normally, we get these amino acids from protein in our diet, and we can also supplement them by taking amino acid supplements if we wish.
Specifically, we require (per kg of bodyweight) a daily average of:
- Histidine: 10 mg
- Isoleucine: 20 mg
- Leucine: 39 mg
- Lysine: 30 mg
- Methionine: 10.4 mg
- Phenylalanine*: 25 mg
- Threonine: 15 mg
- Tryptophan: 4 mg
- Valine: 26 mg
*combined with the non-essential amino acid tyrosine
Source: Protein and Amino Acid Requirements In Human Nutrition: WHO Technical Report
Why this matters
A lot of attention is given to protein, and making sure we get enough of it, especially as we get older, because the risk of sarcopenia (muscle mass loss) increases with age:
However, not every protein comes with a complete set of essential amino acids, and/or have only trace amounts of of some amino acids, meaning that a dietary deficiency can arrive if one’s diet is too restrictive.
And, if we become deficient in even just one amino acid, then bad things start to happen quite soon. We only have so much space, so we’re going to oversimplify here, but:
- Histidine: is needed to produce histamine (vital for immune responses, amongst other things), and is also important for maintaining the myelin sheaths on nerve cells.
- Isoleucine: is very involved in muscle metabolism and makes up the bulk of muscle tissue.
- Leucine: is critical for muscle synthesis and repair, as well as wound healing in general, and blood sugar regulation.
- Lysine: is also critical in muscle synthesis, as well as calcium absorption and hormone production, as well as making collagen.
- Methionine: is very important for energy metabolism, zinc absorption, and detoxification.
- Phenylalanine: is a necessary building block of a lot of neurotransmitters, as well as being a building block of some amino acids not listed here (i.e., the ones your body synthesizes, but can’t without phenylalanine).
- Threonine: is mostly about collagen and elastin production, and is also very important for your joints, as well as fat metabolism.
- Tryptophan: is the body’s primary precursor to serotonin, so good luck making the latter without the former.
- Valine: is mostly about muscle growth and regeneration.
So there you see, the ill effects of deficiency can range from “muscle atrophy” to “brain stops working” and “bones fall apart” and more. In short, any essential amino acid deficiency not remedied will ultimately result in death; we literally become non-viable as organisms without these 9 things.
What to do about it (the “life hack” part)
Firstly, if you eat a lot of animal products, those are “complete” proteins, meaning that they contain all 9 essential amino acids in sensible quantities. The reason that all animal products have these, is because they are just as essential for the other animals as they are for us, so they, just like us, must consume (and thus contain) them.
However, a lot of animal products come with other health risks:
Do We Need Animal Products To Be Healthy? ← this covers which animal products are definitely very health-risky, and which are probably fine according to current best science
…so many people may prefer to get more (or possibly all) dietary protein from plants.
However, plants, unlike us, do not need to consume all 9 essential amino acids, and this may or may not contain them all.
Soy is famously a “complete” protein insofar as it has all the amino acids we need.
But what if you’re allergic to soy?
Good news! Peas are also a “complete” protein and will do the job just fine. They’re also usually cheaper.
Final note
An oft-forgotten thing is that some other amino acids are “conditionally essential”, meaning that while we can technically synthesize them, sometimes we can’t synthesize enough and must get them from our diet.
The conditions that trigger this “conditionally essential” status are usually such things as fighting a serious illness, recovering from a serious injury, or pregnancy—basically, things where your body has to work at 110% efficiency if it wants to get through it in one piece, and that extra 10% has to come from somewhere outside the body.
Examples of commonly conditionally essential amino acids are arginine and glycine.
Arginine is critical for a lot of cell-signalling processes as well as mitochondrial function, as well as being a precursor to other amino acids, including creatine.
As for glycine?

When Doctors Make House Calls, Modern-Style!
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 Tuesday’s newsletter, we asked you foryour opinion of telehealth for primary care consultations*, and got the above-depicted, below-described, set of responses:
- About 46% said “It is no substitute for an in-person meeting with a doctor; let’s keep the human touch”
- About 29% said “It means less waiting and more accessibility, while avoiding transmission of diseases”
- And 25 % said “I find that the pros and cons of telehealth vs in-person balance out, so: no preference”
*We specified that by “primary care” we mean the initial consultation with a non-specialist doctor, before receiving treatment or being referred to a specialist. By “telehealth” we mean by videocall or phonecall.
So, what does the science say?
A quick note first
Because telehealth was barely a thing (statistically speaking) before the first stages of the COVID pandemic, compared to how it is now, most of the science for this is young, and a lot of the science simply hasn’t been done yet, and/or has not been published yet, because the process can take years.
Because of this, some studies we do have aren’t specifically about primary care, and are sometimes about specialists. We think this should not affect the results much, but it bears highlighting.
Nevertheless, we’ll do what we can with the science we have!
Telehealth is more accessible than in-person consultations: True or False?
True, for most people. For example…
❝Data was found from a variety of emergency and non-emergency departments of primary, secondary, and specialised healthcare.
Satisfaction was high among recipients of healthcare, scoring 9-10 on a scale of 0-10 or ranging from 73.3% to 100%.
Convenience was rated high in every specialty examined. Satisfaction of clinicians was high throughout the specialities despite connection failure and concerns about confidentiality of information.❞
whereas…
❝Nonetheless, studies reported perception of increased barriers to accessing care and inequalities for vulnerable patients especially in older people❞
~ Ibid.
Source: Satisfaction with telemedicine use during COVID-19 pandemic in the UK: a systematic review
Now, perception of those things does necessarily equate to an actual increased barrier, but it is reasonable that someone who thinks something is inaccessible will be less inclined to try to access it.
The quality of care provided via telehealth is as good as in-person: True or False?
True, ostensibly, with caveats. The caveats are:
- We’re going offreported patient satisfaction, not objective patient health outcomes (we found little* science as yet for the relative incidence of misdiagnosis, for example—which kind of thing will take time to be revealed).
- We’re also therefore speaking (as statistics do) for the significant majority of people. However, if we happen to be (statistically speaking) an insignificant minority, well, that just sucks for us personally.
*we did find some, but it wasn’t very helpful yet. For example:
An electronic trigger to detect telemedicine-related diagnostic errors
this one does look at the incidence of diagnostic errors, but provides no control group (i.e. otherwise-comparable in-person consultations) for comparison.
While most oft-considered demographic groups reported comparable patient satisfaction (per race, gender, and socioeconomic status, for example), there was one outlier variable, which was age (as we quoted from that first study above).
However!
Looking under the hood of these stats, it seems that age is not the real culprit, so much as technological illiteracy, which is heavily correlated with age:
❝Lower eHealth literacy is associated with more negative attitudes towards I/C technology in healthcare. This trend is consistent across diverse demographics and regions. ❞
Source: Meta-analysis: eHealth literacy and attitudes towards internet/computer technology
There are things that can be done at an in-person consultation that can’t be done by telehealth: True or False?
True, of course. It is incredibly rare that we will cite “common sense”, (as sometimes “common sense” is actually “common mistakes” and is simply and verifiably wrong), but in this case, as one 10almonds subscriber put it:
❝The doctor uses his five senses to assess. This cannot be attained over the phone❞
~ 10almonds subscriber
A quick note first: if your doctor is using their sense of taste to diagnose you, please get a different doctor, because they should definitely not be doing that!
Not in this century, anyway… Once upon a time, diabetes was diagnosed by urine-tasting (and yes, that was a fairly reliable method).
However, nowadays indeed a doctor will use sight, sound, touch, and sometimes even smell.
In a videocall we’re down to two of those senses (sight and sound), and in a phonecall, down to one (sound) and even that is hampered. Your doctor cannot, for example, use a stethoscope over the phone.
With this in mind, it really comes down to what you need from your doctor in that consultation.
- If you’re 99% sure that what you need is to be prescribed an antidepressant, that probably doesn’t need a full physical.
- If you’re 99% sure that what you need is a referral, chances are that’ll be fine by telehealth too.
- If your doctor is 99% sure that what you need is a verbal check-up (e.g. “How’s it been going for you, with the medication that I prescribed for you a month ago?”, then again, a call is probably fine.
If you have a worrying lump, or an unhappy bodily discharge, or an unexplained mysterious pain? These things, more likely an in-person check-up is in order.
Take care!

What immunocompromised people want you to know
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.
While many people in the U.S. have abandoned COVID-19 mitigations like vaccines and masking, the virus remains dangerous for everyone, and some groups face higher risks than others. Immunocompromised people—whose immune systems don’t work as well as they should due to health conditions or medications—are more vulnerable to infection and severe symptoms from the virus.
Public Good News spoke with three immunocompromised people about the steps they take to protect themselves and what they want others to know about caring for each other.
[Editor’s note: The contents of these interviews have been condensed for length.]
PGN: What measures have you been taking to protect yourself since the COVID-19 pandemic began?
Tatum Spears, Virginia
From less than a year old, I had serious, chronic infections and have missed huge chunks of my life. In 2020, I quit my public job, and I have not worked publicly since.
I have a degree in vocal performance and have been singing my whole life, but I haven’t performed publicly since 2019. I feel like a bird without wings. I had to stop traveling. Since no one wears a mask anymore, I can’t go to the movies or social outings or any party.
All my friends live in my phone now. It’s a community of people—a lot of them are immunocompromised or disabled in some way.
There are a good portion of them who just take COVID-19 seriously and want to protect their health, who feel the existential abandonment and the burden of all of this. It’s really isolating having to step back from any sort of social life. I have to assess my risk every single time I leave the house.
Gwendolyn Alyse Bishop, Washington
I was hit by a car when I was very young. I woke up from surgery, and doctors told me I had lost almost all of my spleen. So, I was always the sickest kid in my school.
When COVID-19 hit, I started working from home. At first, I wore cloth masks. I didn’t really learn about KN95 masks until right around the time that COVID-19 disabled me. [Editor’s note: N95 and KN95 masks have been shown to be significantly more effective at preventing the transmission of viral particles than cloth masks.]
I actually don’t get out much anymore because I am disabled by long COVID now, but when I do leave, I wear a respirator in all shared air spaces. My roommate and I have HEPA filters going in every room.And then we test. I have a Pluslife testing dock, and so we keep a weekly testing schedule with that and then test if there are any symptoms. I got reinfected [with COVID-19] last winter, and a Pluslife test helped me catch it early and get Paxlovid. [Editor’s note: Pluslife is a brand of an at-home COVID-19 nucleic acid amplification test, which has been shown to be significantly more effective at detecting COVID-19 than at-home antigen rapid tests.]
Abby Mahler, California
I have lupus, and in 2016, I started taking the drug hydroxychloroquine, which is an immunomodulator. I’m not as immunocompromised as some people, but I certainly don’t have a normal immune system, which has resulted in long-term infections like C. diff.I started masking early. My roommates and I prioritize going outside. We don’t remove our masks inside in public places.
We are in a pod with one other household, and the pod has agreements on the way that we interact with public space. So, we will only unmask with people who have tested ahead of time. We use Metrix, an at-home nucleic acid amplification test.
While it’s not easy and it’s not the life that we had prior to COVID-19’s existence, it is a life that has provided us quite a lot of freedom, in the sense that we are not sick all the time. We are conscientiously making decisions that allow us to have a nice time without a monkey on our backs, which is freeing.
PGN: What do you want people who are not immunocompromised to know?
T.S.: Don’t be afraid to be the only person in a room wearing a mask. Your own health is worth it. And you have to realize how callous [people who don’t wear a mask are] by existing in spaces and breathing [their] air [on immunocompromised people].
People think that vaccines are magic, but vaccines alone are not enough. I would encourage people to look at the Swiss cheese model of risk assessment.
Each slice of Swiss cheese has holes in it in different places, and each layer represents a layer of virus mitigation. One layer is vaccines. Another layer is masks. Then there’s staying home when you’re sick and testing.
G.A.B.: I wish people were masking. I wish people understood how likely it is that they are also now immunocompromised and vulnerable because of the widespread immune dysregulation that COVID-19 is causing. [Editor’s note: Research shows that COVID-19 infections may cause long-term harm to the immune system in some people.]
I want people to be invested in being good community members, and part of that is understanding that COVID-19 hits the poorest the hardest—gig workers, underpaid employees, frontline service workers, people who were already disabled or immunocompromised.
If people want to be good community members, they not only need to protect immunocompromised and disabled people by wearing a mask when they leave their homes, but they also need to actually start taking care of their community members and participating in mutual aid. [Editor’s note: Mutual aid is the exchange of resources and services within a community, such as people sharing extra N95 masks.]
I spend pretty much all of my time working on LongCOVIDAidBot, which promotes mutual aid for people who have been harmed by COVID-19.
A.M.: An important thing to think about when you’re not disabled is that it becomes a state of being for all people, if they’re lucky. You will become disabled, or you will die.
It is a privilege, in my opinion, to become disabled because I can learn different ways of living my life. And being able to see yourself as a body that changes over time, I hope, opens up a way of looking at your body as the porous reality that it is.
Some people think of themselves as being willing to make concessions or change their behavior when immunocompromised people are around, but you don’t always know when someone is immunocompromised.
So, if you’re not willing to change the way that you think about yourself as a person who is susceptible [to illness], then you should change the way that you consider other people around you. Wearing a mask—at the very least in public indoor spaces—means considering the unknown realities of all the people who are interacting with that space.

Elderhood – by Dr. Louise Aronson
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.
Where does “middle age” end, and “old age” begin? By the United States’ CDC’s categorization, human life involves:
- 17 stages of childhood, deemed 0–18
- 5 stages of adulthood, deemed 18–60
- 1 stage of elderhood, deemed 60+
Isn’t there something missing here? Do we just fall off some sort of conveyor belt on our sixtieth birthdays, into one big bucket marked “old”?
Yesterday you were 59 and enjoying your middle age; today you have, apparently, the same medical factors and care needs as a 114-year-old.
Dr. Louise Aronson, a geriatrician, notes however that medical science tends to underestimate the differences found in more advanced old age, and underresearch them. That elders consume half of a country’s medicines, but are not required to be included in clinical trials. That side effects not only are often different than for younger adults, but also can cause symptoms that are then dismissed as “Oh she’s just old”.
She explores, mostly through personal career anecdotes, the well-intentioned disregard that is frequently given by the medical profession, and—importantly—how we might overcome that, as individuals and as a society.
Bottom line: if you are over the age of 60, love someone over the age of 60, this is a book for you. Similarly if you and/or they plan to live past the age of 60, this is also a book for you.

Scattered Minds – by Dr. Gabor Maté
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
This was not the first book that Dr. Maté sat down to write, by far. But it was the first that he actually completed. Guess why.
Writing from a position of both personal and professional experience and understanding, Dr. Maté explores the inaptly-named Attention Deficit Disorder (if anything, there’s often a surplus of attention, just, to anything and everything rather than necessarily what would be most productive in the moment), its etiology, its presentation, and its management.
This is a more enjoyable book than some others by the same author, as while this condition certainly isn’t without its share of woes (often, for example, a cycle of frustration and shame re “why can’t I just do the things; this is ruining my life and it would be so easy if I could just do the things!”), it’s not nearly so bleak as entire books about trauma, addiction, and so forth (worthy as those books also are).
Dr. Maté frames it specifically as a development disorder, and one whereby with work, we can do the development later that (story of an ADHDer’s life) we should have done earlier but didn’t. In terms of practical advice, he includes a program for effecting this change, including as an adult.
The style is easy-reading, in small chapters, with ADHD’d-up readers in mind, giving a strong sense of speeding pleasantly through the book.
Bottom line: when it’s a book by Dr. Gabor Maté, you know it’s going to be good, and this is no exception. Certainly read it if you, anyone you care about, or even anyone you just spend a lot of time around, has ADHD or similar.

Pomegranate’s Health Gifts Are Mostly In Its Peel
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.
Pomegranate Peel’s Potent Potential
Pomegranates have been enjoying a new surge in popularity in some parts, widely touted for their health benefits. What’s not so widely touted is that most of the bioactive compounds that give these benefits are concentrated in the peel, which most people in most places throw away.
They do exist in the fruit too! But if you’re discarding the peel, you’re missing out:
Food Applications and Potential Health Benefits of Pomegranate and its Derivatives
“That peel is difficult and not fun to eat though”
Indeed. Drying the peel, especially freeze-drying it, is a good first step:
❝Freeze drying peels had a positive effect on the total phenolic, tannins and flavonoid than oven drying at all temperature range. Moreover, freeze drying had a positive impact on the +catechin, -epicatechin, hesperidin and rutin concentrations of fruit peel. ❞
Once it is freeze-dried, it is easy to grind it into a powder for use as a nutritional supplement.
“How useful is it?”
Studies with 500mg and 1000mg per day in people with cases of obesity and/or type 2 diabetes saw significant improvements in assorted biomarkers of cardiometabolic health, including blood pressure, blood sugar levels, cholesterol, and hemoglobin A1C:
- Effects of pomegranate extract supplementation on inflammation in overweight and obese individuals: A randomized controlled clinical trial
- Beneficial effects of pomegranate peel extract on plasma lipid profile, fatty acids levels and blood pressure in patients with diabetes mellitus type-2: A randomized, double-blind, placebo-controlled study
It also has anticancer properties:
- Punicalagin, a polyphenol from pomegranate fruit, induces growth inhibition and apoptosis in human PC-3 and LNCaP cells
- Punica granatum (Pomegranate) activity in health promotion and cancer prevention
- The extract from Punica granatum (pomegranate) peel induces apoptosis and impairs metastasis in prostate cancer cells
…and neuroprotective benefits:
- Long-term (15 mo) dietary supplementation with pomegranates attenuates cognitive and behavioral deficits
- Neuroprotective Effects of Pomegranate Peel Extract
- An Evaluation of the Effects of a Non-caffeinated Energy Dietary Supplement on Cognitive and Physical Performance
…and it may protect against osteopenia and osteoporosis, but we only have animal or in vitro studies so far, for example:
- Pomegranate Peel Extract Prevents Bone Loss in a Preclinical Model of Osteoporosis and Stimulates Osteoblastic Differentiation in Vitro
- Pomegranate and its derivatives can improve bone health through decreased inflammation and oxidative stress in an animal model of postmenopausal osteoporosis
Want to try it?
We don’t sell it, but you can buy pomegranates at your local supermarket, or buy the peel extract ready-made from online sources; here’s an example on Amazon for your convenience
(the marketing there is for use of the 100% pomegranate peel powder as a face mask; it also has health benefits for the skin when applied topically, but we didn’t have time to cover that today)
Enjoy!

Shoe Wear Patterns: What They Mean, Why It Matters, & How To Fix It
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.
If you look under your shoes, do you notice how the tread is worn more in some places than others? Specific patterns of shoe wear correspond to how our body applies force, weight, and rotational movement. This reveals how we move, and uneven wear can indicate problematic movement dynamics.
The clues in your shoes
Common shoe wear patterns include:
- Diagonal wear on the outside of the heel: caused by foot angle, leg position, and instability, leading to joint stress.
- Rotational wear at specific points: due to internal or external rotation, often originating from the hip, pelvis, or torso.
- Wear above the big toe: caused by excessive toe lifting, often associated with a “lighter” or kicking leg.
Fixing movement issues to prevent wear involves correcting posture, improving balance, and adjusting how the legs land during walking/running.
Key fixes include:
- Aligning the center of gravity properly to prevent leg overcompensation.
- Ensuring feet land under the hips and not far in front.
- Stabilizing the torso to avoid unnecessary rotation.
- Engaging the glutes effectively to reduce hip flexor dominance and improve leg mechanics.
- Maintaining even weight distribution on both legs to prevent excessive lifting or twisting.
Posture and walking mechanics are vital to reducing uneven wear, but meaningful, lasting change takes time and focused effort, to build new habits.
