Protein: How Much Do We Need, Really?

Mythbusting Protein!

Yesterday, we asked you for your policy on protein consumption. The distribution of responses was as follows:

  • A marginal majority (about 55%) voted for “Protein is very important, but we can eat too much of it”
  • A large minority (about 35%) voted for “We need lots of protein; the more, the better!”
  • A handful (about 4%) voted for “We should go as light on protein as possible”
  • A handful (6%) voted for “If we don’t eat protein, our body will create it from other foods”

So, what does the science say?

If we don’t eat protein, our body will create it from other foods: True or False?

Contingently True on an absurd technicality, but for all practical purposes False.

Our body requires 20 amino acids (the building blocks of protein), 9 of which it can’t synthesize and absolutely must get from food. Normally, we get those amino acids from protein in our diet, and we can also supplement them by buying amino acid supplements.

Specifically, we require (per kg of bodyweight) a daily average of:

  1. Histidine: 10 mg
  2. Isoleucine: 20 mg
  3. Leucine: 39 mg
  4. Lysine: 30 mg
  5. Methionine: 10.4 mg
  6. Phenylalanine*: 25 mg
  7. Threonine: 15 mg
  8. Tryptophan: 4 mg
  9. Valine: 26 mg

*combined with the non-essential amino acid tyrosine

Source: Protein and Amino Acid Requirements In Human Nutrition: WHO Technical Report

However, to get the requisite amino acid amounts, without consuming actual protein, would require gargantuan amounts of supplementation (bearing in mind bioavailability will never be 100%, so you’ll always need to take more than it seems), using supplements that will have been made by breaking down proteins anyway.

So unless you live in a laboratory and have access to endless amounts of all of the required amino acids (you can’t miss even one; you will die), and are willing to do that for the sake of proving a point, then you do really need to eat protein.

Your body cannot, for example, simply break down sugar and use it to make the protein you need.

On another technical note… Do bear in mind that many foods that we don’t necessarily think of as being sources of protein, are sources of protein.

Grains and grain products, for example, all contain protein; we just don’t think of them as that because their macronutritional profile is heavily weighted towards carbohydrates.

For that matter, even celery contains protein. How much, you may ask? Almost none! But if something has DNA, it has protein. Which means all plants and animals (at least in their unrefined forms).

So again, to even try to live without protein would very much require living in a laboratory.

We can eat too much protein: True or False?

True. First on an easy technicality; anything in excess is toxic. Even water, or oxygen. But also, in practical terms, there is such a thing as too much protein. The bar is quite high, though:

❝Based on short-term nitrogen balance studies, the Recommended Dietary Allowance of protein for a healthy adult with minimal physical activity is currently 0.8 g protein per kg bodyweight per day❞

❝To meet the functional needs such as promoting skeletal-muscle protein accretion and physical strength, dietary intake of 1.0, 1.3, and 1.6 g protein per kg bodyweight per day is recommended for individuals with minimal, moderate, and intense physical activity, respectively❞

❝Long-term consumption of protein at 2 g per kg bodyweight per day is safe for healthy adults, and the tolerable upper limit is 3.5 g per kg bodyweight per day for well-adapted subjects❞

❝Chronic high protein intake (>2 g per kg bodyweight per day for adults) may result in digestive, renal, and vascular abnormalities and should be avoided❞

Source: Dietary protein intake and human health

To put this into perspective, if you weigh about 160lbs (about 72kg), this would mean eating more than 144g protein per day, which grabbing a calculator means about 560g of lean beef, or 20oz, or 1¼lb.

If you’re eating quarter-pounder burgers though, that’s not usually so lean, so you’d need to eat more than nine quarter-pounder burgers per day to get too much protein.

High protein intake damages the kidneys: True or False?

True if you have kidney damage already; False if you are healthy. See for example:

High protein intake increases cancer risk: True or False?

True or False depending on the source of the protein, so functionally false:

  • Eating protein from red meat sources has been associated with higher risk for many cancers
  • Eating protein from other sources has been associated with lower risk for many cancers

Source: Red Meat Consumption and Mortality Results From 2 Prospective Cohort Studies

High protein intake increase risk of heart disease: True or False?

True or False depending on the source of the protein, so, functionally false:

  • Eating protein from red meat sources has been associated with higher risk of heart disease
  • Eating protein from other sources has been associated with lower risk of heart disease

Source: Major Dietary Protein Sources and Risk of Coronary Heart Disease in Women

In summary…

Getting a good amount of good quality protein is important to health.

One can get too much, but one would have to go to extremes to do so.

The source of protein matters:

  • Red meat is associated with many health risks, but that’s not necessarily the protein’s fault.
  • Getting plenty of protein from (ideally: unprocessed) sources such as poultry, fish, and/or plants, is critical to good health.
  • Consuming “whole proteins” (that contain all 9 amino acids that we can’t synthesize) are best.

    ❝Question. Suffer from cracked (split) finger tips in the cold weather. Very painful, is there something I can take to ward off this off. Appreciate your daily email.❞

    Ouch, painful indeed! Aside from good hydration (which is something we easily forget in cold weather), there’s no known internal guard against this*, but from the outside, oil-based moisturizers are the way to go.

    Olive oil, coconut oil, jojoba oil, and shea butter are all fine options.

    If the skin is broken such that infection is possible, then starting with an antiseptic ointment/cream is sensible. A good example product is Savlon, unless you are allergic to its active ingredient chlorhexidine.

    *However, if perchance you are also suffering from peripheral neuropathy (a common comorbidity of cracked skin in the extremities), then lion’s main mushroom can help with that.

    Writer’s anecdote: I myself started suffering from peripheral neuropathy in my hands earlier this year, doubtlessly due to some old injuries of mine.

    However, upon researching for the above articles, I was inspired to try lion’s mane mushroom for myself. I take it daily, and have now been free of symptoms of peripheral neuropathy for several months.

    Here’s an example product on Amazon, by the way

    Enjoy!

  • The Modern Art and Science of Mobility – by Aurélien Broussal-Derval

    We’ve reviewed mobility books before, so what makes this one stand out?

    We’ll be honest: the illustrations are lovely.

    The science, the information, the exercises, the routines, the programsAll these things are excellent too, but these can be found in many a book.

    What can’t usually be found is very beautiful (yet no less clear) watercolor paintings and charcoal sketches as anatomical illustrations.

    There are photos too (also of high quality), but the artistry of the paintings and sketches is what makes the reader want to spend time perusing the books.

    At least, that’s what this reviewer found! Because it’s all very well having access to a lot of information (and indeed, I read so much), but making it enjoyable increases the chances of rereading it much more often.

    As for the rest of the content, the book’s information is divided in categories:

    1. Pain (what causes it, what it means, and how to manage it)
    2. Breathing (yes, a whole section devoted to this, and it is aligned heavily to posture also, as well as psychological state and the effect of stress on tension, inflammation, and more)
    3. Movement (this is mostly about kinds of movement and ranges of movement)
    4. Mobility (this is about aggregating movements as a fully mobile human)

    So, each builds on from the previous because any pain needs addressing before anything else, breathing (and with it, posture) comes next, then we learn about movement, then we bring it all together for mobility.

    Bottom line: this is a beautiful and comprehensive book that will make learning a joy

  • Why Everyone You Don’t Like Is A Narcissist

    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.

    We’ve written before about how psychiatry tends to name disorders after how they affect other people, rather than how they affect the bearer, and this is most exemplified when it comes to personality disorders. For example:

    “You have a deep insecurity about never being good enough, and you constantly mess up in your attempt to overcompensate? You may have Evil Bastard Disorder!”

    “You have a crippling fear of abandonment and that you are fundamentally unloveable, so you do all you can to try to keep people close? You must have Manipulative Bitch Disorder!”

    See also: Miss Diagnosis: Anxiety, ADHD, & Women

    Antisocial Diagnoses

    These days, it is easy to find on YouTube countless videos of how to spot a narcissist, with a list of key traits that all mysteriously describe exactly the exes of everyone in the comments.

    And these days it is mostly “narcissist”, because “psychopath” and “sociopath” have fallen out of popular favor a bit:

    • perhaps for coming across as overly sensationalized, and thus lacking credibility
    • perhaps because “Narcissistic Personality Disorder (NPD)” exists in the DSM-5 (the US’s latest “Diagnostic and Statistical Manual of Mental Disorders”), while psychopathy and sociopathy are not mentioned as existing.

    You may be wondering: what do “psychopathy” and “sociopathy” mean?

    And the answer is: they mean whatever the speaker wants them to mean. Their definitions and differences/similarities have been vigorously debated by clinicians and lay enthusiasts alike for long enough that the scientific world has pretty much given up on them and moved on.

    Stigma vs pathology

    Because of the popular media (and social media) representation of NPD, it is easy to armchair diagnose one’s relative/ex/neighbor/in-law/boss/etc as being a narcissist, because the focus is on “narcissists do these bad things that are mean to people”.

    If the focus were instead on “narcissists have cripplingly low self-esteem, and are desperate to not show weakness in a world they have learned is harsh and predatory”, then there may not be so many armchair diagnoses—or at the very least, the labels may be attached with a little more compassion, the same way we might with other mental health issues such as depression.

    Not that those with depression get an easy time of it socially either—society’s response is generally some manner of “aren’t you better yet, stop being lazy”—but at the very least, depressed people are not typically viewed with hatred.

    A quick aside: if you or someone you know is struggling with depression, here are some things that actually help:

    The Mental Health First-Aid You’ll Hopefully Never Need

    The disorder is not the problem

    Maybe your relative, ex, neighbor, etc really is clinically diagnosable as a narcissist. There are still two important things to bear in mind:

    • After centuries of diagnosing people with mental health maladies that we now know don’t exist per se (madness, hysteria, etc), and in recent decades countless revisions to the DSM and similar tomes, thank goodness we now have the final and perfect set of definitions that surely won’t be re-written in the next few years or so ← this is irony; it will absolutely be re-written numerous times yet because of course it’s still not a magically perfect descriptor of the broad spectrum of human nature
    • The disorder is not the problem; the way they treat (or have treated) you is the problem.

    For example, let’s take a key thing generally attributed to narcissists: a lack of empathy

    Now, empathy can be divided into:

    • affective empathy: the ability to feel what other people are feeling
    • cognitive empathy: the ability to intellectually understand what other people are feeling (akin to sympathy, which is the same but with the requisite of having experienced the thing in question oneself)

    A narcissist (as well as various other people without NPD) will typically have negligible affective empathy, and their cognitive empathy may be a little sluggish too.

    Sluggish = it may take them a beat longer than most people, to realize what an external signifier of emotions means, or correctly guess how something will be felt by others. This can result in gravely misspeaking (or inappropriately emoting), after failing to adequately quickly “read the room” in terms of what would be a socially appropriate response. To save face, they may then either deny/minimize the thing they just said/did, or double-down on it and go on [what for them feels like] the counterattack.

    As to why this shutting off of empathy happens: they have learned that the world is painful, and that people are sources of pain, and so—to avoid further pain—have closed themselves off to that, often at a very early age. This will also apply to themselves; narcissists typically have negligible self-empathy too, which is why they will commonly make self-destructive decisions, even while trying to put themselves first.

    Important note on how this impacts other people: the “Golden Rule” of “treat others as you would wish to be treated” becomes intangible, as they have no more knowledge of their own emotional needs than they do of anyone else’s, so cannot make that comparison.

    Consider: if instead of being blind to empathy, they were colorblind… You would probably not berate them for buying green apples when you asked for red. They were simply incapable of seeing that, and consequently made a mistake. So it is when it’s a part of the brain that’s not working normally.

    So… Since the behavior does adversely affect other people, what can be done about it? Even if “hate them for it and call for their eradication from the face of the Earth” is not a reasonable (or compassionate) option, what is?

    Take the bull by the horns

    Above all, and despite all appearances, a narcissist’s deepest desire is simply to be accepted as good enough. If you throw them a life-ring in that regard, they will generally take it.

    So, communicate (gently, because a perceived attack will trigger defensiveness instead, and possibly a counterattack, neither of which are useful to anyone) what behavior is causing a problem and why, and ask them to do an alternative thing instead.

    And, this is important, the alternative thing has to be something they are capable of doing. Not merely something that you feel they should be capable of doing, but that they are actually capable of doing.

    • So not: “be a bit more sensitive!” because that is like asking the colorblind person to “be a bit more observant about colors”; they are simply not capable of it and it is folly to expect it of them, because no matter how hard they try, they can’t.
    • But rather: “it upsets me when you joke about xyz; I know that probably doesn’t make sense to you and that’s ok, it doesn’t have to. I am asking, however, if you will please simply refrain from joking about xyz. Would you do that for me?”

    Presented with such, it’s much more likely that the narcissist will drop their previous attempt to be good enough (by joking, because everyone loves someone with a sense of humor, right?) for a new, different attempt to be good enough (by showing “behold, look, I am a good person and doing the thing you asked, of which I am capable”).

    That’s just one example, but the same methodology can be applied to most things.

    For tricks pertaining to how to communicate such things without causing undue resistance, see:

    We know genes make a big difference to a lot about us, but how much? And, the genes we have, we’re stuck with, right?

    Dr. Sharon Moalem shines a bright light into some of the often-shadowier nooks and crannies of our genetics, covering such topics as:

    • How much can (and can’t) be predicted from our parents’ genes—even when it comes to genetic traits that both parents have, and Gregor Mendel himself would (incorrectly) think obvious
    • How even something so seemingly simple and clear as genetic sex, very definitely isn’t
    • How traumatic life events can cause epigenetic changes that will scar us for generations to come
    • How we can use our genetic information to look after our health much better
    • How our life choices can work with, or overcome, the hand we got dealt in terms of genes

    The style of the book is conversational, down to how there’s a lot of “I” and “you” in here, and the casual style belies the heavy, sharp, up-to-date science contained within.

    Bottom line: if you’d like insight into the weird and wonderful nuances of genetics as found in this real, messy, perfectly chaotic world, this book is an excellent choice.

  • The Most Anti Aging Exercise

    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.

    We’ve referenced this (excellent) video before, but never actually put it under the spotlight in one of these features, so here we go!

    Deep squats

    It’s about deep squats, also called Slav squats, Asian squats, sitting squats, resting squats, or various other names. However, fear not; you don’t need to be Slavic or Asian to do it; you just need to practice.

    As for why this is called “anti-aging”, by the way, it’s because being able to get up off the ground is one of the main tests of age-related mobility decline, and if you can deep-squat comfortably, then you can do that easily. And so long as you continue being able to deep-squat comfortably, you’ll continue to be able to get up off the ground easily too, because you have the strength in the right muscles, as well as the suppleness, comfort with range of motion, and balance (those stabilizing muscles are used constantly in a deep squat, whereas Western lifestyle sitting leaves those muscles very neglected and thus atrophied).

    Epidemiological note: chairs, couches, and assorted modern conveniences reduce the need for squatting in daily life, leading to stiffness in joints, muscles, tendons, and ligaments. Many adults in developed countries struggle with deep squats due to lack of use, not aging. Which is a problem, because a lack of full range of motion in joints causes wear and tear, leading to chronic pain and degenerative joint diseases. People in countries where squatting is a common resting position have lower incidences of osteoarthritis, for example—contrary to what some might expect, squatting does not harm joints but rather protects them from arthritis and knee pain. Strengthening leg muscles through squatting can alleviate knee pain, whereas knee pain is often worsened by inactivity.

    Notwithstanding the thumbnail, which is showing an interim position, one’s feet should be flat on the ground, by the way, and one’s butt should be nearby, just a few inches off the ground (in other words, the position that we see her in for most of this video).

    Troubleshooting: if you’re accustomed to sitting in chairs a lot, then this may be uncomfortable at first. Zuzka advises us to go gently, and/but gradually increase our range of motion and (equally importantly) duration in the resting position.

    You can use a wall or doorway to partially support you, at first, if you struggle with mobility or balance. Just try to gradually use it less, until you’re comfortable deep-squatting with no support.

    Since this is not an intrinsically very exciting exercise, once you build up the duration for which you’re comfortable deep-squatting, it can be good to get in the habit of “sitting” this way (i.e. deep squatting, still butt-off-the-floor, but doing the job of sitting) while doing other things such as working (if you have an appropriate work set-up for that*), reading, or watching TV.

    *this is probably easiest with a laptop placed on an object/surface of appropriate height, such as a coffee table or such. As a bonus, having your hands in front of you while working will also bring your center of gravity forwards a bit, making the position easier and more comfortable to maintain. This writer (hi, it’s me) prefers her standing desk for work in general, with a nice ergonomic keyboard and all that, but if using a laptop from time to time, then squatting is a very good option.

    In terms of working up duration, if you can only manage seconds to start with, that’s fine. Just do a few more seconds each time, until it’s 30, 60, 120, and so on until it’s 5 minutes, 10, 15, and so on.

    You can even start that habit-forming while you’re still in the “seconds at a time” stage! You can deep-squat just for some seconds while you:

    • pick up something from the floor
    • check on something in the oven
    • get something out of the bottom of the fridge

    …etc!
