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?

Perfectionism, And How To Make Yours Work For You
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.
Harness The Power Of Your Perfectionism
A lot of people see perfectionism as a problem—and it can be that!
We can use perfectionism as a would-be shield against our fear of failure, by putting things off until we’re better prepared (repeat forever, or at least until the deadliniest deadline that ever deadlined), or do things but really struggle to draw a line under them and check them off as “done” because we keep tweaking and improving and improving… With diminishing returns (forever). So, that’s not helpful.
But, if we’re mindful, we can also leverage our perfectionism to our benefit.
Great! How?
First we need to be able to discern the ways in which perfectionism can be bad or good for us. Or as it’s called in psychology, ways in which our perfectionism can be maladaptive or adaptive.
- Maladaptive: describing a behavioral adaptation to our environment—specifically, a reactive behavioral adaptation that is unhealthy and really is not a solution to the problem at hand
- Adaptive: describing a behavioral adaptation to our environment—specifically, a responsive behavioral adaptation that is healthy and helps us to thrive
So in the case of perfectionism, one example for each might be:
- Maladaptive: never taking up that new hobby, because you’re just going to suck at it anyway, and what’s the point if you’re not going to excel? You’re a perfectionist, and you don’t settle for anything less than excellence.
- Adaptive: researching the new hobby, learning the basics, and recognizing that even if the results are not immediately perfect, the learning process can be… Yes, even with mistakes along the way, for they too are part of learning! You’re a perfectionist, and you’re going to be the best possible student of your new hobby.
Did you catch the key there?
When it comes to approaching things we do in life—either because we want to or because we must—there are two kinds of mindset: goal-oriented, and task-oriented.
Broadly speaking, each has their merits, and as a general topic, it’s beyond the scope of today’s main feature. Here we’re looking at it in the context of perfectionism, and in that frame, there’s a clear qualitative difference:
- The goal-oriented perfectionist will be frustrated to the point of torment, at not immediately attaining the goal. Everything short of that will be a means to an end, at best. Not fun.
- The task-oriented perfectionist will take joy in going about the task in the best way possible, and optimizing their process as they go. The journey itself will be rewarding and a tangible product of their consistent perfectionism.
The good news is: you get to choose! You’re not stuck in a box.
If you’re thinking “I’m a perfectionist and I’m generally a goal-oriented person”, that’s fine. You’re just going to need to reframe your goals.
- Instead of: my goal is to be fluent in Arabic
- …so you never speak it, because to err is human, all too human, and you’re a perfectionist, so you don’t want that!
- Let’s try: my goal is to study Arabic for at least 15 minutes per day, every day, without fail, covering at least some new material each time, no matter how small the increase
- …and then you go and throw yourself into conversation way out of your depth, make mistakes, and get corrections, because that’s how you learn, and you’re a perfectionist, so you want that!
This goes for any field of expertise, of course.
- If you want to play the violin solo in Carnegie Hall, you have to pick up your violin and practice each day.
- If you want to be a world-renowned pastry chef, you have to make a consistent habit of baking.
- If you want to write a bestselling book, you have to show up at your keyboard.
Be perfect all you want, but be the perfect student.
And as your skills grow, maybe you’ll upgrade that to also being the perfect practitioner, and perhaps later still, the perfect teacher.
But just remember:
Perfection comes not from the end goal (that would be backwards thinking!) but from the process (which includes mistakes; they’re an important part of learning; embrace them and grow!), so perfect that first.

The Polyvagal Theory – by Dr. Stephen Porges
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.
Do you ever find that your feelings (or occasionally: lack thereof) sometimes can seem mismatched with the observed facts of your situation? This book unravels that mystery—or rather, that stack of mysteries.
Dr. Porges’ work on this topic is, by the way, the culmination of 40 years of research. While he’s not exactly a household name to the layperson, he’s very respected in his field, and this book is his magnum opus.
Here he explains the disparate roles of the two branches of the vagus nerve (hence: polyvagal theory). At least, the two branches that we mammals have; non-mammalian vertebrates have only one. This makes a big difference, because of the cascade of inhibitions that this allows.
The answer to the very general question “What stops you from…?” is usually found somewhere down this line of cascade of inhibitions.
These range from “what stops you from quitting your job/relationship/etc” to “what stops you from freaking out” to “what stops you from relaxing” to “what stops you from reacting quickly” to “what stop you from giving up” to “what stops you from gnawing your arm off” and many many more.
And because sometimes we wish we could do something that we can’t, or wish we wouldn’t do something that we do, understanding this process can be something of a cheat code to life.
A quick note on style: the book is quite dense and can be quite technical, but should be comprehensible to any layperson who is content to take their time, because everything is explained as we go along.
Bottom line: if you’d like to better understand the mysteries of how you feel vs how you actually are, and what that means for what you can or cannot wilfully do, this is a top-tier book

100 Things Productive People Do – by Nigel Cumberland
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 is a book of a hundred small chapters (the book is 396 pages, so 2–3 pages per chapter) which makes for a feeling of quick reading, and definitely gives an option of “light bites”, dipping into the book here and there.
Cumberland offers a wide range of practical wisdom here, and while the book is (per the title) focused on productivity, it also includes all due weight to not burning out and/or breaking down. Because things productive people do does not, it turns out, include working themselves directly into an early grave.
But—despite the author’s considerable and obvious starting point of social privilege—nor is this a tome of “offer your genius leadership and otherwise just coast while everyone does your work for you”, either. This is a “brass tacks” book and highly relatable whether your to-do list most prominently features “personally manage the merger of these Fortune 500 companies” or “sort out that junk in the spare room”
Bottom line: we’d be surprised if this book with 100 pieces of advice failed to bring you enough value to more than pay for itself!

Winter Wellness – by Rachel de Thample
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.
Winter is often the season of comfort foods and, in much of the Western world, there’s a holiday season slide of forgotten diets and instead sugar, alcohol, pastry, and the like.
What de Thample does here is an antidote to all that, without sacrificing happiness and celebration.
Before the recipes get started, she has a chapter on “food as medicine“, and to our immense surprise, proceeds to detail, accurately, many categories such as
- Foods for immune health
- Foods against inflammation
- Foods for gut health
- Foods against aging
- Foods for energy levels
- Foods against anxiety
- Foods for hormonal balance
…and so forth, with lists of ingredients that fit into each category.
Then in the rest of the book, she lays out beautiful recipes for wonderful dishes (and drinks) that use those ingredients, without unhealthy additions.
The recipes are, by the way, what could best be categorized as “fancy”. However, they are fancy in the sense that they will be impressive for entertaining, and (again, to our great surprise) they don’t actually call for particularly expensive/rare ingredients, nor for arcane methods and special equipment.Instead, everything’s astonishingly accessible to put together and easy to execute.
Bottom line: if you’d like to indulge this winter, but would like to do so healthily, this is an excellent way to do so.

Red Cabbage vs White Cabbage – 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 red cabbage to white cabbage, we picked the red.
Why?
Perhaps you guessed this one, based on the “darker and/or more colorful foods are usually more nutritionally dense” dictum. That’s not always true, by the way, but it is a good rule of thumb and it is correct here. In the case of cabbages, each type is a nutritional powerhouse, but red does beat white:
In terms of macros, they’re quite comparable. They’re both >90% water with just enough other stuff (carbs, fiber, protein) to hold them together, and the “other stuff” in question is quite similarly proportioned in both cases. Within the carbs, even the sugar breakdown is similar. There are slight differences, but the differences are not only tiny, but also they balance out in any case.
When it comes to vitamins, as you might expect, the colorful red cabbage does better with more of vitamins A, B1, B2, B3, B6, C, and choline, while white has more of vitamins B5, B9, E, and K. So, a 7:4 win for red.
In the category of minerals, it’s even more polarized; red cabbage has more calcium, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. On the other hand, white contains a tiny amount more copper.
In short, both are great (red just makes white look bad by standing next to it, but honestly, white has lots of all those same things too, just not quite as much as red), and this writer will continue to use white when making her favorite shchi, but if you’re looking for the most nutritionally dense option, it’s red.

Marathons in Mid- and Later-Life
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? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
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
We had several requests pertaining to veganism, meatless mondays, and substitutions in recipes—so we’re going to cover those on a different day!
As for questions we’re answering today…
Q: Is there any data on immediate and long term effects of running marathons in one’s forties?
An interesting and very specific question! We didn’t find an overabundance of studies specifically for the short- and long-term effects of marathon-running in one’s 40s, but we did find a couple of relevant ones:
The first looked at marathon-runners of various ages, and found that…
- there are virtually no relevant running time differences (p<0.01) per age in marathon finishers from 20 to 55 years
- the majority of middle-aged and elderly athletes have training histories of less than seven years of running
From which they concluded:
❝The present findings strengthen the concept that considers aging as a biological process that can be considerably speeded up or slowed down by multiple lifestyle related factors.❞
See the study: Performance, training and lifestyle parameters of marathon runners aged 20–80 years: results of the PACE-study
The other looked specifically at the impact of running on cartilage, controlled for age (45 and under vs 46 and older) and activity level (marathon-runners vs sedentary people).
The study had the people, of various ages and habitual activity levels, run for 30 minutes, and measured their knee cartilage thickness (using MRI) before and after running.
They found that regardless of age or habitual activity level, running compressed the cartilage tissue to a similar extent. From this, it can be concluded that neither age nor marathon-running result in long-term changes to cartilage response to running.
Or in lay terms: there’s no reason that marathon-running at 40 should ruin your knees (unless you are doing something wrong).
That may or may not have been a concern you have, but it’s what the study looked at, so hey, it’s information.
Here’s the study: Functional cartilage MRI T2 mapping: evaluating the effect of age and training on knee cartilage response to running
Q: Information on [e-word] dysfunction for those who have negative reactions to [the most common medications]?
When it comes to that particular issue, one or more of these three factors are often involved:
- Hormones
- Circulation
- Psychology
The most common drugs (that we can’t name here) work on the circulation side of things—specifically, by increasing the localized blood pressure. The exact mechanism of this drug action is interesting, albeit beyond the scope of a quick answer here today. On the other hand, the way that they work can cause adverse blood-pressure-related side effects for some people; perhaps you’re one of them.
To take matters into your own hands, so to speak, you can address each of those three things we just mentioned:
Hormones
Ask your doctor (or a reputable phlebotomy service) for a hormone test. If your free/serum testosterone levels are low (which becomes increasingly common in men over the age of 45), they may prescribe something—such as testosterone shots—specifically for that.
This way, it treats the underlying cause, rather than offering a workaround like those common pills whose names we can’t mention here.
Circulation
Look after your heart health; eat for your heart health, and exercise regularly!
Cold showers/baths also work wonders for vascular tone—which is precisely what you need in this matter. By rapidly changing temperatures (such as by turning off the hot water for the last couple of minutes of your shower, or by plunging into a cold bath), your blood vessels will get practice at constricting and maintaining that constriction as necessary.
Psychology
[E-word] dysfunction can also have a psychological basis. Unfortunately, this can also then be self-reinforcing, if recalling previous difficulties causes you to get distracted/insecure and lose the moment. One of the best things you can do to get out of this catch-22 situation is to not worry about it in the moment. Depending on what you and your partner(s) like to do in bed, there are plenty of other equally respectable options, so just switch track!
Having a conversation about this in advance will probably be helpful, so that everyone’s on the same page of the script in that eventuality, and it becomes “no big deal”. Without that conversation, misunderstandings and insecurities could arise for your partner(s) as well as yourself (“aren’t I desirable enough?” etc).
So, to recap, we recommend:
- Have your hormones checked
- Look after your circulation
- Make the decision to have fun!
