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

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?

Corn Chips vs Potato Chips: 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 corn chips to potato chips, we picked the corn chips.
Why?
First, let it be said, this was definitely a case of “lesser evil voting” as there was no healthy choice here. But as for which is relatively least unhealthy…
Most of the macronutrient and micronutrient profile is quite similar. Both foods are high carb, moderately high fat, negligible protein, and contain some trace minerals and even some tiny amounts of vitamins. Both are unhealthily salty.
Exact numbers will of course vary from one brand’s product to another, but you can see some indicative aggregate scores here in the USDA’s “FoodData Central” database:
The biggest health-related difference that doesn’t have something to balance it out is that the glycemic index of corn chips averages around 63, whereas the glycemic index of potato chips averages around 70 (that is worse).
That’s enough to just about tip the scales in favor of corn chips.
The decision thus having been made in favor of corn chips (and the next information not having been part of that decision), we’ll mention one circumstantial extra benefit to corn chips:
Corn chips are usually eaten with some kind of dip (e.g. guacamole, sour cream, tomato salsa, etc) which can thus deliver actual nutrients. Potato chips meanwhile are generally eaten with no additional nutrients. So while we can’t claim the dip as being part of the nutritional make-up of the corn chips, we can say:
If you’re going to have a habit of eating one or the other, then corn chips are probably the least unhealthy of the two.
And yes, getting vegetables (e.g. in the dips) in ways that are not typically associated with “healthy eating” is still better than not getting vegetables at all!

Young Mind Young Body – by Sue Ziang
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 very “healthy mind in a healthy body” book, consistent with the author’s status as a holistic health coach. Sometimes that produces a bit of a catch-22 regarding where to start, but for Ziang, the clear answer is to start with the mind, and specifically, one’s perception of one’s own age.
She advocates for building a young mind in a young body, and yes, that’s mind-building much like body-building. This does not mean any kind of wilful self-delusion, but rather, choosing the things that we do get to choose along the way.
The bridge between mind and body, for Ziang, is meditation—which is reasonable, as it’s very much mind-stuff and also very much neurological and has a very real-world impact on the body’s broader health, even simply by such mechanisms as changing breathing, heart rate, neurotransmitter levels, endocrine functions, and the like.
When it comes to the more physical aspects of health, her dietary advice is completely in line with what we write here at 10almonds. Hydrate well, eat more plants, especially beans and greens and whole grains, get good fats in, enjoy spices, practice mindful eating, skip the refined carbohydrates, be mindful of bio-individuality (e.g. one’s own personal dietary quirks that stem from physiology; some of us react differently to this kind of food or that for genetic reasons, and that’s not something to be overlooked).
In the category of exercise, she’s simply about moving more, which while not comprehensive, is not bad advice either.
Bottom line: if you’re looking for an “in” to holistic health and wondering where to start, this book is a fine and very readable option.

Proteins Of The Week
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 week’s news round-up is, entirely by chance, somewhat protein-centric in one form or another. So, check out the bad, the very bad, the mostly good, the inconvenient, and the worst:
Mediterranean diet vs the menopause
Researchers looked at hundreds of women with an average age of 51, and took note of their dietary habits vs their menopause symptoms. Most of them were consuming soft drinks and red meat, and not good in terms of meeting the recommendations for key food groups including vegetables, legumes, fruit, fish and nuts, and there was an association between greater adherence to Mediterranean diet principles, and better health.

Listeria in meat
This one’s not a study, but it is relevant important news. The headline pretty much says it all, so if you don’t eat meat, this isn’t one you need to worry about any further than that. If you do eat meat, though, you might want to check out the below article to find out whether the meat you eat might be carrying listeria:

Brawn and brain?
A study looked at cognitively healthy older adults (of whom, 57% women), and found an association between their muscle strength and their psychological wellbeing. Note that when we said “cognitively healthy”, this means being free from dementia etc—not necessarily psychologically health in all respects, such as also being free from depression and enjoying good self-esteem.

The protein that blocks bone formation
This one’s more clinical but definitely of interest to any with osteoporosis or at high risk of osteoporosis. Researchers identified a specific protein that blocks osteoblast function, thus more of this protein means less bone production. Currently, this is not something that we as individuals can do anything about at home, but it is promising for future osteoporosis meds development.

Rabies risk
People associate rabies with “rabid dogs”, but the biggest rabies threat is actually bats, and they don’t even need to necessarily bite you to confer the disease (it suffices to have licked the skin, for instance—and bats are basically sky-puppies who will lick anything). Because rabies has a 100% fatality rate in unvaccinated humans, this is very serious. This means that if you wake up and there’s a bat in the house, it doesn’t matter if it hasn’t bitten anyone; get thee to a hospital (where you can get the vaccine before the disease takes hold; this will still be very unpleasant but you’ll probably survive so long as you get the vaccine in time).
Read in full: What to know about bats and rabies
Related: Dodging Dengue In The US ← much less serious than rabies, but still not to be trifled with—particularly noteworthy if you’re in an area currently affected by floodwaters or even just unusually heavy rain, by the way, as this will leave standing water in which mosquitos breed.

Healthy Habits for Managing & Reversing Prediabetes – by Dr. Marie Feldman
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.
The book doesn’t assume prior knowledge, and does explain the science of diabetes, prediabetes, the terms and the symptoms, what’s going on inside, etc—before getting onto the main meat of the book, the tips.
The promised 100 tips are varied in their application; they range from diet and exercise, to matters of sleep, stress, and even love.
There are bonus tips too! For example, an appendix covers “tips for healthier eating out” (i.e. in restaurants etc) and a grocery list to ensure your pantry is good for defending you against prediabetes.
The writing style is very accessible pop-science; this isn’t like reading some dry academic paper—though it does cite its sources for claims, which we always love to see.
Bottom line: if you’d like to proof yourself against prediabetes, and are looking for “small things that add up” habits to get into to achieve that, this book is an excellent first choice.

Ghanaian Red Bean & Sweet Potato Groundnut Stew
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 dish popular in principle throughout West Africa. We say “in principle” because that’s a big place, and there is a lot of regional variation. The archetypal peanut stew is from Senegal (as maafe) or Mali (as tigadèguèna), but for its more balanced nutritional profile we’ve chosen one from Ghana—and since there are regional variations within Ghana too, we should specify that this one is from the south.
If you are allergic to nuts, you can substitute a seed butter (or tahini) for the nut butter, and omit the nuts—this will work in culinary terms and be fine healthwise, but we can’t claim it would be the same dish, having lost its defining ingredient. If your allergy is solely to peanuts, then substituting with any oily nut would work. So, not almonds for example, but cashews or even walnuts would be fine.
You will need
- 1½ lbs sweet potatoes, peeled and cut into ½” cubes
- 2 cups low-sodium vegetable stock
- 2 cans kidney beans, drained, cooked, and rinsed (or 2 cups same; cooked, drained, and rinsed)
- 1 can chopped tomatoes
- ½ cup unsalted dry-roasted peanuts
- 1 onion, chopped
- 1 red bell pepper, deseeded and chopped
- ¼ bulb garlic, finely chopped
- 2 heaped tbsp unsalted peanut butter, minimal (ideally: no) additives
- 2 tsp white miso paste
- 2 tsp grated fresh ginger
- 1 tsp ground cumin
- 1 tsp cayenne pepper
- 1 tsp black pepper
- ½ tsp MSG or 1 tsp low-sodium salt
- ½ tsp coarsely ground nigella seeds
- Extra virgin olive oil
Method
(we suggest you read everything at least once before doing anything)
1) Heat some oil in a sauté pan, or other pan suitable for both frying and fitting the entire stew in. Fry the onions until softened, turn the heat down low, and add the garlic, ginger, red bell pepper, cumin, cayenne, black pepper, and MSG/salt.
2) Add ¼ cup of the vegetable stock, and the sweet potato, and turn the heat back up, on high for about 30 seconds to get it to temperature, and then take it down to a simmer.
3) Stir in the miso paste and chopped tomatoes.
4) Add most of the rest of the vegetable stock, keeping ¼ cup aside. Simmer for about 20 minutes.
5) Stir in the kidney beans, and simmer for about 30 minutes more—the sweet potato should be soft now; if it isn’t, let it simmer a while longer until it is.
6) Combine the peanut butter with the remaining ¼ cup vegetable stock, and blend until smooth. Stir it into the stew.
7) If the stew is looking more like a soup than a stew, take out 1 cup and blend this 1 cup to a purée, adding it back in.
8) Add half the peanuts unto the stew. Taste, and adjust the seasonings if necessary.
9) Crush the remaining peanuts using a pestle and mortar; not too much though; you want them broken into bits, not pulverised.
10) Garnish with the crushed nuts and nigella seeds, and serve.
Enjoy!

The Science and Technology of Growing Young – by Sergey Young
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.
There are a lot of very optimistic works out there that promise the scientific breakthroughs that will occur very soon. Even amongst the hyperoptimistic transhumanism community, there is the joke of “where’s my flying car?” Sometimes prefaced with “Hey Ray, quick question…” as a nod to (or sometimes, direct address to) Ray Kurzweil, the Google computer scientist and futurist.
So, how does this one measure up?
Our author, Sergey Young, is not a scientist, but an investor with fingers in many pies. Specifically, pies relating to preventative medicine and longevity. Does that make him an unreliable narrator? Not necessarily, but it means we need to at least bear that context in mind.
But, also, he’s investing in those fields because he believes in them, and wants to benefit from them himself. In essense, he’s putting his money where his mouth is. But, enough about the author. What of the book?
It’s a whirlwind tour of the main areas of reseach and development, in the recent past, the present, and the near future. He talks about problems, and compelling solutions to problems.
If the book has a weak point, it’s that it doesn’t really talk about the problems to those solutions—that is, what can still go wrong. He’s excited about what we can do, and it’s somebody else’s job to worry about pitfalls along the way.
As to the “and what you can do now?” We’ll summarize:
- Mediterranean diet, mostly plant-based
- Get moderate exercise daily
- Get good sleep
- Don’t drink or smoke
- Get your personal health genomics data
- Get regular medical check-ups
- Look after your mental health too
Bottom line: this is a great primer on the various avenues of current anti-aging research and development, with discussion ranging from the the technological to the sociological. It has some health tips too, but the real meat of the work is the insight into the workings of the longevity industry.
