Get PEA-Brained!

Today we’ll be looking at phenylethylamine, or PEA, to its friends.

Not to be mistaken for the related amino acid phenylalanine! Both ultimately have effects on the dopaminergic system, but the process and benefits are mostly quite different.

We thought we’d do this one in the week of Valentine’s Day, because of its popular association with love:

❝Phenylethylamine (PEA), an amphetamine-like substance that has been alluringly labeled the “chemical of love,” makes the best case for the love-chocolate connection since it has been shown that people in love may actually have higher levels of PEA in their brain, as surmised from the fact that their urine is richer in a metabolite of this compound. In other words, people thrashing around in the throes of love pee differently from others.❞

What is it?

It’s an amino acid. Because we are mammals, we can synthesize it inside our bodies, so it’s not considered an “essential amino acid”, i.e. one that we need to get from our diet. It is found in some foods, though, including:

  • Other animals, especially other mammals
  • Various beans, legumes, nuts, seeds. In particular almonds, soybeans, lentils, and chickpeas score highly
  • Fermented foods
  • Chocolate (popular lore holds this to be a good source of PEA; science finds it to be a fair option, but not in the same ballpark as the other items)

Fun fact: the reason Marvel’s Venom has a penchant for eating humans and chocolate is (according to the comics) because phenylethylamine is an essential amino acid for it.

What does it do for us?

It’s a Central Nervous System (CNS) stimulant, and also helps us synthesize critical neurotransmitters such as dopamine, norepinephrine (adrenaline) and serotonin:

β-Phenylethylamine Alters Monoamine Transporter Function via Trace Amine-Associated Receptor 1: Implication for Modulatory Roles of Trace Amines in Brain

It works similarly, but not identically, to amphetamines:

Amphetamine potentiates the effects of β-phenylethylamine through activation of an amine-gated chloride channel

Is it safe?

We normally do this after the benefits, but “it works similarly to amphetamines” may raise an eyebrow or two, so let’s do it here:

  • It is recommended to take no more than 500mg/day, with 100mg–500mg being typical doses
  • It is not recommended to take it at all if you have, or have a predisposition to, any kind of psychotic disorder (especially schizophrenia, or bipolar disorder wherein you sometimes experience mania)
    • This isn’t a risk for most people, but if you fall into the above category, the elevated dopamine levels could nudge you into a psychotic/manic episode that you probably don’t want.

See for example: Does phenylethylamine cause schizophrenia?

There are other contraindications too, so speak with your doctor/pharmacist before trying it.

On the other hand, if you are considering ADHD medication, then phenylethylamine could be a safer thing to try first, to see if it helps, before going to the heavy guns of actual amphetamines (as are commonly prescribed for ADHD). Same goes for depression and antidepressants.

What can I expect from PEA?

More dopamine, norepinephrine, and serotonin. Mostly the former two. Which means, you can expect stimulation.

For focus and attention, it’s so effective that it has been suggested (as we mentioned above) as a safer alternative to ADHD meds:

β-phenylethylamine, a small molecule with a large impact

…and may give similar benefits to people without ADHD, namely improved focus, attention, and mental stamina:

Integrative Psychiatry | The Many Health Benefits of Phenylethylamine (PEA) – The Brain’s Natural Stimulant

It also improves mood:

❝Phenylethylamine (PEA), an endogenous neuroamine, increases attention and activity in animals and has been shown to relieve depression in 60% of depressed patients. It has been proposed that PEA deficit may be the cause of a common form of depressive illness.

Effective dosage did not change with time. There were no apparent side effects. PEA produces sustained relief of depression in a significant number of patients, including some unresponsive to the standard treatments. PEA improves mood as rapidly as amphetamine but does not produce tolerance.

  • Lacking Motivation? Science Has The Answer

    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 Science Of Motivation (And How To Use It To Your Advantage)

    When we do something rewarding, our brain gets a little (or big!) spike of dopamine. Dopamine is popularly associated with pleasure—which is fair— but there’s more to it than this.

    Dopamine is also responsible for motivation itself, as a prime mover before we do the thing that we find rewarding. If we eat a banana, and enjoy it, perhaps because our body needed the nutrients from it, our brain gets a hit of dopamine.

    (and not because bananas contain dopamine; that dopamine is useful for the body, but can’t pass the blood-brain barrier to have an effect on the brain)

    So where does the dopamine in our brain come from? That dopamine is made in the brain itself.

    Key Important Fact: the brain produces dopamine when it expects an activity to be rewarding.

    If you take nothing else away from today’s newsletter, let it be this!

    It makes no difference if the activity is then not rewarding. And, it will keep on motivating you to do something it anticipated being rewarding, no matter how many times the activity disappoints, because it’ll remember the very dopamine that it created, as having been the reward.

    To put this into an example:

    • How often have you spent time aimlessly scrolling social media, flitting between the same three apps, or sifting through TV channels when “there’s nothing good on to watch”?
    • And how often did you think afterwards “that was a good and rewarding use of my time; I’m glad I did that”?

    In reality, whatever you felt like you were in search of, you were really in search of dopamine. And you didn’t find it, but your brain did make some, just enough to keep you going.

    Don’t try to “dopamine detox”, though.

    While taking a break from social media / doomscrolling the news / mindless TV-watching can be a great and healthful idea, you can’t actually “detox” from a substance your body makes inside itself.

    Which is fortunate, because if you could, you’d die, horribly and miserably.

    If you could “detox” completely from dopamine, you’d lose all motivation, and also other things that dopamine is responsible for, including motor control, language faculties, and critical task analysis (i.e. planning).

    This doesn’t just mean that you’d not be able to plan a wedding; it also means:

    • you wouldn’t be able to plan how to get a drink of water
    • you wouldn’t have any motivation to get water even if you were literally dying of thirst
    • you wouldn’t have the motor control to be able to physically drink it anyway

    Read: Dopamine and Reward: The Anhedonia Hypothesis 30 years on

    (this article is deep and covers a lot of ground, but is a fascinating read if you have time)

    Note: if you’re wondering why that article mentions schizophrenia so much, it’s because schizophrenia is in large part a disease of having too much dopamine.

    Consequently, antipsychotic drugs (and similar) used in the treatment of schizophrenia are generally dopamine antagonists, and scientists have been working on how to treat schizophrenia without also crippling the patient’s ability to function.

    Do be clever about how you get your dopamine fix

    Since we are hardwired to crave dopamine, and the only way to outright quash that craving is by inducing anhedonic depression, we have to leverage what we can’t change.

    The trick is: question how much your motivation aligns with your goals (or doesn’t).

    So if you feel like checking Facebook for the eleventieth time today, ask yourself: “am I really looking for new exciting events that surely happened in the past 60 seconds since I last checked, or am I just looking for dopamine?”

    You might then realize: “Hmm, I’m actually just looking for dopamine, and I’m not going to find it there”

    Then, pick something else to do that will actually be more rewarding. It helps if you make a sort of dopa-menu in advance, of things to pick from. You can keep this as a list on your phone, or printed and pinned up near your computer.

    Examples might be: Working on that passion project of yours, or engaging in your preferred hobby. Or spending quality time with a loved one. Or doing housework (surprisingly not something we’re commonly motivated-by-default to do, but actually is rewarding when done). Or exercising (same deal). Or learning that language on Duolingo (all those bells and whistles the app has are very much intentional dopamine-triggers to make it addictive, but it’s not a terrible outcome to be addicted to learning!).

    Basically… Let your brain’s tendency to get led astray work in your favor, by putting things in front of it that will lead you in good directions.

    Things for your health and/or education are almost always great things to allow yourself the “ooh, shiny” reaction and pick them up, try something new, etc.

  • Time Smart – by Dr. Ashley Whillans

    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.

    First, what this is not: it’s not a productivity book.

    What is rather: a book of better wellbeing.

    There is a little overlap, insofar as getting “time smart” in the ways that Dr. Whillans recommends will give you more ability to also be more productive—if that’s what you want.

    She talks us through time traps and the “time poverty epidemic”, as well as steps to finding time and funding time. Perhaps most critical idea-wise is the chapter on building a “time-affluence habit”, making decisions that prioritize your time-freedom where you can—which in turn will allow you to build yet more. Kind of like compound interest really, but for time.

    The writing style is a conversational tone, but peppered with bullet-point lists and charts and the like from time to time, and often with citations to back up claims. It makes for a very readable book, and yet one that’s also inspiring of the confidence that it’s more than just one person’s opinion.

    Bottom line: if you sometimes feel like you could do everything you want to if you could just find the time, this book can help you get there.

  • Our Top 5 Spices: How Much Is Enough For Benefits?

    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.

    A spoonful of pepper makes the… Hang on, no, that’s not right…

    We know that spices are the spice of life, and many have great health-giving qualities. But…

    1. How much is the right amount?
    2. What’s the minimum to get health benefits?
    3. What’s the maximum to avoid toxicity?

    That last one always seems like a scary question, but please bear in mind: everything is toxic at a certain dose. Oxygen, water, you-name-it.

    On the other hand, many things have a toxicity so low that one could not physically consume it sufficiently faster than the body eliminates it, to get a toxic build-up.

    Consider, for example, the €50 banknote that was nearly withdrawn from circulation because one of the dyes used in it was found to be toxic. However, the note remained in circulation after scientists patiently explained that a person would have to eat many thousands of them to get a lethal dose.

    So, let’s address these questions in reverse order:

    What’s the maximum to avoid toxicity?

    In the case of the spices we’ll look at today, the human body generally* has high tolerance for them if eaten at levels that we find comfortable eating.

    *IMPORTANT NOTE: If you have (or may have) a medical condition that may be triggered by spices, go easier on them (or if appropriate, abstain completely) after you learn about that.

    Check with your own physician if unsure, because not only are we not doctors, we’re specifically not your doctors, and cannot offer personalized health advice.

    We’re going to be talking in averages and generalizations here. Caveat consumator.

    For most people, unless you are taking the spice in such quantities that you are folding space and seeing the future, or eating them as the main constituents of your meal rather than an embellishment, you should be fine. Please don’t enter a chilli-eating contest and sue us.

    What is the minimum to get health benefits and how much should we eat?

    The science of physiology generally involves continuous rather than discrete data, so there’s not so much a hard threshold, as a point at which the benefits become significant. The usefulness of most nutrients we consume, be they macro- or micro-, will tend to have a bell curve.

    In other words, a tiny amount won’t do much, the right amount will have a good result, and usefulness will tail off after that point. To that end, we’re going to look at the “sweet spot” of peaking on the graph.

    Also note: the clinical dose is the dose of the compound, not the amount of the food that one will need to eat to get that dose. For example, food x containing compound y will not usually contain that compound at 100% rate and nothing else. We mention this so that you’re not surprised when we say “the recommended dose is 5mg of compound, so take a teaspoon of this spice”, for example.

    Further note: we only have so much room here, so we’re going to list only the top benefits, and not delve into the science of them. You can see the related main features for more details, though!

    The “big 5” health-giving spices, with their relevant active compound:

    • Black pepper (piperine)
    • Hot pepper* (capsaicin)
    • Garlic (allicin)
    • Ginger (gingerol)
    • Turmeric (curcumin**)

    *Cayenne pepper is very high in capsaicin; chilli peppers are also great

    **not the same thing as cumin, which is a completely different plant. Cumin does have some health benefits of its own, but not in the same league as the spices above, and there’s only so much we have room to cover today.

    Black pepper

    • Benefits: antioxidant, anti-cancer, boosts bioavailability of other nutrients, aids digestion
    • Dosage: 5–20mg for benefits
    • Suggestion: ½ teaspoon of black pepper is sufficient for benefits. However, this writer’s kitchen dictum in this case is “if you can’t see the black pepper in/on the food, add more”—but that’s more about taste!
    • Related main feature: Black Pepper’s Anti-Cancer Arsenal (And More)

    Hot Pepper

    Garlic

    • Benefits: heart health, blood sugar balancing, anti-cancer
    • Dosage: 4–8µg for benefits
    • Suggestion: 1–2 cloves daily is generally good. However, cooking reduces allicin content (and so does oxidation after cutting/crushing), so you may want to adjust accordingly if doing those things.
    • Related main feature: The Many Health Benefits Of Garlic

    Ginger

    • Benefits: anti-inflammatory, antioxidant, anti-nausea
    • Dosage: 3–4g for benefits
    • Suggestion: 1 teaspoon grated raw ginger or ½ a teaspoon powdered ginger, can be used in baking or as part of the seasoning for a stir-fry
    • Related main feature: Ginger Does A Lot More Than You Think

    Turmeric

    Closing notes

    The above five spices are very healthful for most people. Personal physiology can and will vary, so if in doubt, a) check with your doctor b) start at lowest doses and establish your tolerance (or lack thereof).

    Enjoy, and stay well!

    We’ll Try To Make This Easy To Digest

    Do you have a digestion-related problem?

    If so, you’re far from alone; around 40% of Americans have digestive problems serious enough to disrupt everyday life:

    New survey finds forty percent of Americans’ daily lives are disrupted by digestive troubles

    …which puts Americans just a little over the global average of 35%:

    Global Burden of Digestive Diseases: A Systematic Analysis of the Global Burden of Diseases Study, 1990 to 2019

    Mostly likely on account of the Standard American Diet, or “SAD” as it often gets abbreviated in scientific literature.

    There’s plenty we can do to improve gut health, for example:

    Today we’re going to be examining digestive enzyme supplements!

    What are digestive enzymes?

    Digestive enzymes are enzymes that break down food into stuff we can use. Important amongst them are:

    • Protease: breaks down proteins (into amino acids)
    • Amylase: breaks down starches (into sugars)
    • Lipase: breaks down fats (into fatty acids)

    All three are available as popular supplements to aid digestion. How does the science stack up for them?

    Protease

    For this, we only found animal studies like this one, but the results have been promising:

    Exogenous protease supplementation to the diet enhances growth performance, improves nitrogen utilization, and reduces stress

    Amylase

    Again, the studies for this alone (not combined with other enzymes) have been solely from animal agriculture; here’s an example:

    The Effect of Exogenous Amylase Supplementation on the Nutritional Value of Peas

    Lipase

    Unlike for protease and amylase, now we have human studies as well, and here’s what they had to say:

    ❝Lipase supplementation significantly reduced stomach fullness without change of EGG.

    Furthermore, lipase supplementation may be helpful in control of FD symptom such as postprandial symptoms❞

    ~ Dr. Seon-Young Park & Dr. Jong-Sun Rew

    Read more: Is Lipase Supplementation before a High Fat Meal Helpful to Patients with Functional Dyspepsia?

    (short answer: yes, it is)

    More studies found the same, such as:

    Lipase Supplementation before a High-Fat Meal Reduces Perceptions of Fullness in Healthy Subjects

    All together now!

    When we look at studies for combination supplementation of digestive enzymes, more has been done, and/but it’s (as you might expect) less specific.

    The following paper gives a good rundown:

    Pancrelipase Therapy: A Combination Of Protease, Amylase, & Lipase

    Is it safe?

    For most people it is quite safe, but if taking high doses for a long time it can cause problems, and also there may be complications if you have diabetes, are otherwise immunocompromised, or have some other conditions (listed towards the end of the above-linked paper, along with further information that we can’t fit in here).

    As ever, check with your doctor/pharmacist if you’re not completely sure!

    Have you ever felt you could get everything in your life in order, if you could just get a little breathing room first?

    Notwithstanding the title, this is mostly not a book about breathing exercises. It does cover that too, but there’s a lot more.

    The author’s advices draw from a variety of high quality sources. Well-read readers will certainly recognise sections that are straight from David Allen’s “Getting Things Done”, and Mihaly Czikszentmihalyi’s “Flow”, for example, as well as Francesco Cirillo’s “Pomodoro Technique”, and James Clear’s “Atomic Habits”.

    We also learn about how even simple yoga can help us, and good sleep, and a healthy diet.

    In short, if you’ve been reading 10almonds for a while, you might not actually learn much new! But it’s very nice to have all these things in one book, for sure, and it’s a pleasant, easy read too.

    Bottom line: if you’d like to streamline your life and not have to buy a whole stack of different books to do it, this book is a great composite that will enable you to get the job done efficiently.

    Curcumin (Turmeric) is worth its weight in gold

    Not financially! But, this inexpensive golden spice has an impressive list of well-studied health benefits, for something so freely available in any supermarket, and there’s a reason it gets a place in “Dr. Greger’s Daily Dozen”, right up there with things like “leafy greens” and “berries” when it comes to superfoods.

    Let’s do a quick run-down:

    In short, it’s—like we said—worth its weight in gold.

    Quick advice though before we move on…

    If you take curcumin with black pepper, it allows your body to use the curcumin around 2,000% better. This goes whether you’re cooking with both, or take them as a supplement (they’re commonly sold as a combo-capsule for this reason).
