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:

  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

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:

Protein vs Sarcopenia

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:

  1. 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.
  2. Isoleucine: is very involved in muscle metabolism and makes up the bulk of muscle tissue.
  3. Leucine: is critical for muscle synthesis and repair, as well as wound healing in general, and blood sugar regulation.
  4. Lysine: is also critical in muscle synthesis, as well as calcium absorption and hormone production, as well as making collagen.
  5. Methionine: is very important for energy metabolism, zinc absorption, and detoxification.
  6. 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).
  7. Threonine: is mostly about collagen and elastin production, and is also very important for your joints, as well as fat metabolism.
  8. Tryptophan: is the body’s primary precursor to serotonin, so good luck making the latter without the former.
  9. 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?

  • Buckwheat vs Bulgur Wheat – 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 buckwheat to bulgur, we picked the buckwheat.

    Why?

    First, some things to know up front:

    • Bulgur wheat is a kind of cracked wheat product. As such, it contains wheat, and yes, gluten.
    • Buckwheat is not a wheat, nor even a grass, but a flowering plant. Buckwheat is as related to wheat as a lionfish is to a lion. It does not contain gluten.
    • Buckwheat can be purchased whole or hulled. We went with whole. If you go with hulled, the percentages of vitamins and minerals will be relatively higher, and/but this will be because you lost the fibrous husk, so they’ll be commensurately lower in fiber. If you were to go with hulled, we’d still pick it over bulgur wheat though, just for a different reason (as in that case, the vitamin and mineral contents would be more overwhelmingly in buckwheat’s favor, even though it’d have less fiber).

    Ok, now that those things are covered…

    Looking at the macronutrients, there’s not a lot between them, except that buckwheat has the much lower glycemic index (this is only the case if you got whole, not hulled—if you got hulled, the glycemic index would be about the same).

    In terms of vitamins, buckwheat has more of vitamins B2, B5, B9, E, K, and choline, while bulgur wheat technically has more vitamin A, but the numbers are tiny; a cup of bulgur wheat will give you 0.12% of the RDA. So, an easy win (functionally: 5:0) for buckwheat.

    When it comes to minerals, buckwheat has more copper, magnesium, potassium, and selenium, while bulgur wheat has more calcium and manganese. They’re equal on iron and phosphorus, making this a 4:2 win for buckwheat.

    Adding up the categories makes this a clear win for buckwheat!

  • Five Supplements That Actually Work Vs Arthritis

    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 Dr. Diana Girnita, a double board-certified physician (internal medicine & rheumatology) who, in addition to her MD, also has a PhD in immunology—bearing in mind that rheumatoid arthritis is an autoimmune condition.

    Her mission is to help people with any form of arthritis (rheumatoid or otherwise) and those with many non-arthritic autoimmune conditions (ranging from tendonitis to lupus) to live better.

    Today, we’ll be looking at her recommendations of 5 supplements that actually help alleviate arthritis:

    Collagen

    Collagen famously supports skin, nails, bones, and joint cartilage; Dr. Girnita advises that it’s particularly beneficial for osteoarthritis.

    Specifically, she recommends either collagen peptides or hydrolyzed collagen, as they are most absorbable. However, collagen can also be sourced from foods like bone broth, fish with skin and bones, and gelatin-based foods.

    If you’re vegetarian/vegan, then it becomes important to simply consume the ingredients for collagen, because like most animals, we can synthesize it ourselves provided we get the necessary nutrients. For more on that, see:

    We Are Such Stuff As Fish Are Made Of

    Glucosamine & chondroitin

    Technically two things, but almost always sold/taken together. Naturally found in joint cartilage, it can slow cartilage breakdown and reduce pain in osteoarthritis.

    Studies show pain relief, especially in moderate-to-severe cases; best taken long-term. Additionally, it’s a better option than NSAIDs for patients with heart or gastrointestinal issues.

    10almonds tip: something that’s tricker to find as a supplement than glucosamine and chondroitin, but you might want to check it out:

    Omega-3 fatty acids

    Dr. Girnita recommends this one because unlike the above recommendations that mainly help reduce/reverse the joint damage itself, omega-3 reduces inflammation, pain, and stiffness, and can decrease or eliminate the need for NSAIDs in rheumatoid arthritis and psoriatic arthritis.

    She recommends 2-4g EPA/DHA daily; ideally taken with a meal for better absorption.

    She also recommends to look for mercury-free options—algae-derived are usually better than fish-derived, but check for certification either way! See also:

    What Omega-3 Fatty Acids Really Do For Us

    Boswellia serrata (frankincense)

    Popularly enjoyed as an incense but also available in supplement form, it contains boswellic acid, which reduces inflammation and cartilage damage.

    Dr. Girnita recommends 100 mg daily, but advises that it may interact with some antidepressants, anti-anxiety medications, and NSAIDs—so speak with your pharmacist/doctor if unsure.

    We also wrote about this one here:

    Science-Based Alternative Pain Relief

    Curcumin (turmeric)

    Well-known for its potent anti-inflammatory properties, it’s comparable to NSAIDs in pain relief for most common forms of arthritis.

    Dr. Girnita recommends 1–1.5g of curcumin daily, ideally combined with black pepper for better absorption:

    Why Curcumin (Turmeric) Is Worth Its Weight In Gold

    Lastly…

    Dr. Girnita advises to not blindly trust supplements, but rather, to test them for 2–3 months while keeping a journal of your symptoms. If it improves things for you, keep it up, if not, discontinue. Humans can be complicated and not everything will work exactly the same way for everyone!

  • 8 Signs Of High Cortisol & How To Reverse “Cortisol Face”

    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.

    Dr. Shereene Idriss has insights about the facial features that might indicate chronically elevated cortisol levels, and what to do about same:

    At face value

    Dr. Idriss notes that for most people, this should not be cause for undue concern, although hypercortisolism can also be associated with genetic disorders such as Cushing’s syndrome, as well as prolonged use of certain medication, or the presence of certain tumors. As well as facial swelling, hypercortisolism can also result in other physical changes like acne, weight gain, skin thinning, stretch marks, infections, and hair loss.

    As for what to do about it, she recommends addressing lifestyle factors like poor sleep, unhealthy diet, alcohol consumption, and lack of hydration to reduce facial puffiness related to stress. Diet suggestions include incorporating foods rich in magnesium, vitamin C, and omega-3s, such as leafy greens, fatty fish, nuts and seeds, and berries.

    She also suggests some supplements to consider, such as ashwagandha, magnesium, omega-3s, and/or l-theanine, but you might want to speak to your doctor/pharmacist to check in case of contraindications per any other conditions you may have, or medications you may be on.

    When Age’s Brain-Changes Come Knocking

    A woman guarding in a red dress.

    This is Dr. Amy Friday. She’s a psychologist, specializing in geropsychology and neuropsychological assessments.

    In other words, she helps people optimize their aging experience, particularly in the context of brain changes as we get older.

    What does she want us to know?

    First: be not afraid

    Ominous first words, but the fact is, there’s a lot to find scary about the prospect of memory loss, dementia, and death.

    However, as she points out:

    • Death will come for us all sooner or later, barring technology as yet unknown
    • Dementia can be avoided, or at least stalled, or at least worked around
    • Memory loss, as per the above, can be avoided/stalled/managed

    We’ve written a little on these topics too:

    Managing Your Mortality

    …or if the death is not yours:

    Bereavement & Managing Grief

    As for avoiding dementia, the below-linked feature is about Alzheimer’s in particular (which accounts for more than half of all cases of dementia), but the advice goes for most of the other kinds too:

    How To Reduce Your Alzheimer’s Risk

    And finally, about memory loss specifically:

    How To Boost Your Memory Immediately (Without Supplements)

    this one is especially about cementing into one’s brain the kinds of memories that people most fear losing with age. People don’t worry about forgetting their PIN codes; they worry about forgetting their cherished memories with loved ones. So, if that’s important to you, do consider checking out this one!

    What is that about managing or working around the symptoms?

    If we’re missing a limb, we (usually) get a prosthetic, and/or learn how to operate without that limb.

    If we’re missing sight or hearing, partially or fully, there are disability aids for those kinds of things too (glasses are a disability aid! Something being very common does not make it not a disability; you literally have less of an ability—in this case, the ability to see), and/or we learn how to operate with our different (or missing) sense.

    Dr. Friday makes the case for this being the same with memory loss, dementia, and other age-related symptoms (reduced focus, increased mental fatigue, etc):

    ❝We are all screwed up. Here’s my flavor … what’s yours? This is a favorite saying of mine, because we ARE all screwed up in one way or another, and when we acknowledge it we can feel closer in our screwed-up-edness.

    We are all experiencing “normal aging,” so that tip-of-the-tongue phenomenon that starts in our thirties and slowly gets worse is REAL. But what if you’re having more problems than normal aging? Is it time to throw in the towel and hide? I’m hoping that there is a group of people who say HELL NO to that idea.

    Let’s use lessons from research and clinical practice to help all of us work around our weaknesses, and capitalize on our strengths.  ❞

    ~ Dr. Amy Friday

    Examples of this might include:

    • Writing down the things most important to you (a short list of information and/or statements that you feel define you and what matters most to you), so that you can read it later
    • Making sure you have support (partner, family, friends, etc) who are on the same page about this topic—and thus will actually support you and advocate for you, instead of arguing about what is in your best interest without consulting you.
    • Labelling stuff around the house, so that you get less confused about what is what and where it is
    • Having a named go-to advocate that you can call / ask to be called, if you are in trouble somewhere and need help that you can rely on
    • Getting a specialized, simpler bank account; hiring an accountant if relevant and practicable.

    The thing is, we all want to keep control. Sometimes we can do that! Sometimes we can’t, and if we’re going to lose some aspect of control, it’ll generally go a lot better if we do it on our own terms, so that we ourselves can look out for future-us in our planning.

  • What Menopause Does To The Heart

    World Menopause Day: Menopause & Cardiovascular Disease Risk

    Today, the 18th of October, is World Menopause Day.

    The theme for this year is cardiovascular disease (CVD), and if your first reaction is to wonder what that has to do with the menopause, then this is the reason why it’s being featured. Much of the menopause and its effects are shrouded in mystery; not because of a lack of science (though sometimes a bit of that too), but rather, because it is popularly considered an unimportant, semi-taboo topic.

    So, let’s be the change we want to see, and try to fix that!

    What does CVD have to do with the menopause?

    To quote Dr. Anjana Nair:

    ❝The metabolic and clinical factors secondary to menopause, such as dyslipidemia, insulin resistance, fat redistribution and systemic hypertension, contribute to the accelerated risk for cardiovascular aging and disease.

    Atherosclerosis appears to be the end result of the interaction between cardiovascular risk factors and their accentuation during the perimenopausal period.

    The increased cardiovascular risk in menopause stems from the exaggerated effects of changing physiology on the cardiovascular system.❞

    Can we do anything about it?

    Yes, we can! Here be science:

    This (in few words: get your hormone levels checked, and consider HRT if appropriate) is consistent with the advice from gynecologist Dr. Jen Gunter, whom we featured back in August:
