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.

  • Is it OK to lie to someone with dementia?

    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 was disagreement on social media recently after a story was published about an aged care provider creating “fake-away” burgers that mimicked those from a fast-food chain, to a resident living with dementia. The man had such strict food preferences he was refusing to eat anything at meals except a burger from the franchise. This dementia symptom risks malnutrition and social isolation.

    But critics of the fake burger approach labelled it trickery and deception of a vulnerable person with cognitive impairment.

    Dementia is an illness that progressively robs us of memories. Although it has many forms, it is typical for short-term recall – the memory of something that happened in recent hours or days – to be lost first. As the illness progresses, people may come to increasingly “live in the past”, as distant recall gradually becomes the only memories accessible to the person. So a person in the middle or later stages of the disease may relate to the world as it once was, not how it is today.

    This can make ethical care very challenging.

    Is it wrong to lie?

    Ethical approaches classically hold that specific actions are moral certainties, regardless of the consequences. In line with this moral absolutism, it is always wrong to lie.

    But this ethical approach would require an elderly woman with dementia who continually approaches care staff looking for their long-deceased spouse to be informed their husband has passed – the objective truth.

    Distress is the likely outcome, possibly accompanied by behavioural disturbance that could endanger the person or others. The person’s memory has regressed to a point earlier in their life, when their partner was still alive. To inform such a person of the death of their spouse, however gently, is to traumatise them.

    And with the memory of what they have just been told likely to quickly fade, and the questioning may resume soon after. If the truth is offered again, the cycle of re-traumatisation continues.

    A different approach

    Most laws are examples of absolutist ethics. One must obey the law at all times. Driving above the speed limit is likely to result in punishment regardless of whether one is in a hurry to pick their child up from kindergarten or not.

    Pragmatic ethics rejects the notion certain acts are always morally right or wrong. Instead, acts are evaluated in terms of their “usefulness” and social benefit, humanity, compassion or intent.

    The Aged Care Act is a set of laws intended to guide the actions of aged care providers. It says, for example, psychotropic drugs (medications that affect mind and mood) should be the “last resort” in managing the behaviours and psychological symptoms of dementia.

    Instead, “best practice” involves preventing behaviour before it occurs. If one can reasonably foresee a caregiver action is likely to result in behavioural disturbance, it flies in the face of best practice.

    What to say when you can’t avoid a lie?

    What then, becomes the best response when approached by the lady looking for her husband?

    Gentle inquiries may help uncover an underlying emotional need, and point caregivers in the right direction to meet that need. Perhaps she is feeling lonely or anxious and has become focused on her husband’s whereabouts? A skilled caregiver might tailor their response, connect with her, perhaps reminisce, and providing a sense of comfort in the process.

    This approach aligns with Dementia Australia guidance that carers or loved ones can use four prompts in such scenarios:

    • acknowledge concern (“I can tell you’d like him to be here.”)
    • suggest an alternative (“He can’t visit right now.”)
    • provide reassurance (“I’m here and lots of people care about you.”)
    • redirect focus (“Perhaps a walk outside or a cup of tea?”)

    These things may or may not work. So, in the face of repeated questions and escalating distress, a mistruth, such as “Don’t worry, he’ll be back soon,” may be the most humane response in the circumstances.

    Different realities

    It is often said you can never win an argument with a person living with dementia. A lot of time, different realities are being discussed.

    So, providing someone who has dementia with a “pretend” burger may well satisfy their preferences, bring joy, mitigate the risk of malnutrition, improve social engagement, and prevent a behavioural disturbance without the use of medication. This seems like the correct approach in ethical terms. On occasion, the end justifies the means.

  • Insomnia Decoded – by Dr. Audrey Porter

    We’ve written about sleep books before, so what makes this one different? Its major selling point is: most of the focus isn’t on the things that everyone already knows.

    Yes, there’s a section on sleep hygiene and yes it’ll tell you to cut the caffeine and alcohol, but most of the advice here is beyond that.

    Rather, it looks at finding out (if you don’t already know for sure) what is keeping you from healthy sleep, be it environmental, directly physical, or psychological, and breaking out of the stress-sleep cycle that often emerges from such.

    The style is light and conversational, but includes plenty of science too; Dr. Porter knows her stuff.

    Bottom line: if you feel like you know what you should be doing, but somehow life keeps conspiring to stop you from doing it, then this is the book that could help you break out that cycle.

  • Remember – by Dr. Lisa Genova

    Memory is often viewed as one thing—either you have a good memory, or you don’t. At best, a lot of people have a vague idea of selective memory. But, the reality is much more complex—and much more interesting.

    Dr. Genova lays out clearly and simply the various different kinds of memory, how they work, and how they fail. Some of these kinds of memory operate on completely different principles than others, and/or in different parts of the brain. And, it’s not just “a memory for faces” or a “memory for names”, nor even “short term vs long term”. There’s working memory, explicit and implicit memory, semantic memory, episodic memory, muscle memory, and more.

    However, this is not just an interesting book—it’s also a useful one. Dr. Genova also looks at how we can guard against failing memory in later years, and how we can expand and grow the kinds of memory that are most important to us.

    The style of the book is very conversational, and not at all textbook-like. It’s certainly very accessible, and pleasant to read too.

    Bottom line: memory is a weird and wonderful thing, and this book shines a clear light on many aspects of it—including how to improve the various different kinds of memory.

    Fear not, this is not a “think healing thoughts” New Age sort of book. In fact, it’s quite the contrary.

    The most common negative reviews for this on Amazon are that it is too densely packed with scientific studies, and some readers found it hard to get through since they didn’t find it “light reading”.

    Counterpoint: this reviewer found it very readable. A lot of it is as accessible as 10almonds content, and a lot is perhaps halfway between 10almonds content in readability, and the studies we cite. So if you’re at least somewhat comfortable reading academic literature, you should be fine.

    The author, a professor of psychology (tenured at Harvard since 1981), examines a lot of psychosomatic effect. Psychosomatic effect is often dismissed as “it’s all in your head”, but it means: what’s in your head has an effect on your body, because your brain talks to the rest of the body and directs bodily responses and actions/reactions.

    An obvious presentation of this in medicine is the placebo/nocebo effect, but Dr. Langer’s studies (indeed, many of the studies she cites are her own, from over the course of her 40-year career) take it further and deeper, including her famous “Counterclockwise” study in which many physiological markers of aging were changed (made younger) by changing the environment that people spent time in, to resemble their youth, and giving them instructions to act accordingly while there.

    In the category of subjective criticism: the book is not exceptionally well-organized, but if you read for example a chapter a day, you’ll get all the ideas just fine.

    Bottom line: if you want a straightforward hand-holding “how-to” guide, this isn’t it. But it is very much information-packed with a lot of ideas and high-quality science that’s easily applicable to any of us.

  • No Equipment Muscle Gain Routine for Ages 50+

    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.

    Sarcopenia, the loss of muscle mass commonly associated with aging, can be a big problem as it leaves us vulnerable to injury (and also isn’t great for the metabolism—keeping adequate muscle mass ensures keeping the metabolism ticking over nicely). Will Harlow, over-50s specialist physiotherapist, is here to share a routine that works without weights:

    Where it counts

    There’s a fair amount of emphasis here on the lower body and core. That’s because in practical terms, this is what matters more for our health than having bulging biceps:

    • First exercise: donkey calf raises to build strength in the calves using a chair.
    • Second exercise: single-leg elevated lunge to work the quads and glutes, using a step or books for elevation.
    • Third exercise: slow sit-to-stand for quads, glutes, and core strength, focusing on a slow descent.
    • Fourth exercise: wall press-up to strengthen the chest, shoulders, and arms, with a variation using towels for increased resistance.
    • Final exercise: shoulder raises using bottles or similar weights to target the shoulders and rotator cuffs.

    Ok, so that last one was a slight cheat on his part as it does require grabbing a weight, but it’s not specialist equipment at least, and can just be something you grabbed at home. It’s also the least important of the five exercises, and can be skipped if necessary.

  • How Much Does A Vegan Diet Affect Biological Aging?

    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.

    Slow Your Aging, One Meal At A Time

    This one’s a straightforward one today, and the ““life hack” can be summed up:

    Enjoy a vegan diet to enjoy younger biological age.

    First, what is biological age?

    Biological age is not one number, but a collection of numbers, as per different biomarkers of aging, including:

    • Visual markers of aging (e.g. wrinkles, graying hair)
    • Performative markers of aging (e.g. mobility tests)
    • Internal functional markers of aging (e.g. tests for cognitive decline, eyesight, hearing, etc)
    • Cellular markers of aging (e.g. telomere length)

    We wrote more about this here:

    Age & Aging: What Can (And Can’t) We Do About It?

    A vegan diet may well impact multiple of those categories of aging, but today we’re highlighting a study (hot off the press; published only a few days ago!) that looks at its effect on that last category: cellular markers of aging.

    There’s an interesting paradox here, because this category is:

    • the most easily ignorable; because we all feel it if our knees are giving out or our skin is losing elasticity, but who notices if telomeres’ T/S ratio changed by 0.0407? ← the researchers, that’s who, as this difference is very significant
    • the most far-reaching in its impact, because cellular aging in turn has an effect on all the other markers of aging

    Second, how much difference does it make, and how do we know?

    The study was an eight-week interventional identical twin study. This means several things, to start with:

    • Eight weeks is a rather short period of time to accumulate cellular aging, let alone for an intervention to accumulate a significant difference in cellular aging—but it did. So, just imagine what difference it might make in a year or ten!
    • Doing an interventional study with identical twin pairs already controlled for a lot of factors, that are usually confounding variables in population / cohort / longitudinal / observational studies.

    Factors that weren’t controlled for by default by using identical twins, were controlled for in the experiment design. For example, twin pairs were rejected if one or more twin in a given pair already had medical conditions that could affect the outcome:

    ❝Inclusion criteria involved participants aged ≥18, part of a willing twin pair, with BMI <40, and LDL-C <190 mg/dL. Exclusions included uncontrolled hypertension, metabolic disease, diabetes, cancer, heart/renal/liver disease, pregnancy, lactation, and medication use affecting body weight or energy.

    Eligibility was determined via online screening, followed by an orientation meeting and in-person clinic visit. Randomization occurred only after completing baseline visits, dietary recalls, and questionnaires for both twins❞

    ~ Dr. Varun Dwaraka et al. ← there’s a lot of “et al.” to this one; the paper had 16 collaborating authors!

    As to the difference it made over the course of the 8 weeks…

    ❝Various measures of epigenetic age acceleration (PC GrimAge, PC PhenoAge, DunedinPACE) were assessed, along with system-specific effects (Inflammation, Heart, Hormone, Liver, and Metabolic).

    Distinct responses were observed, with the vegan cohort exhibiting significant decreases in overall epigenetic age acceleration, aligning with anti-aging effects of plant-based diets. Diet-specific shifts were noted in the analysis of methylation surrogates, demonstrating the influence of diet on complex trait prediction through DNA methylation markers.❞

    ~ Ibid.

    You can read the whole paper here (it goes into a lot more detail than we have room to here, and also gives infographics, charts, numbers, the works):

    Unveiling the epigenetic impact of vegan vs. omnivorous diets on aging: insights from the Twins Nutrition Study (TwiNS)

    Were they just eating more healthily, though?

    Well, arguably yes, as the results show, but to be clear:

    The omnivorous diet compared to the vegan diet in this study was also controlled; both groups were given a healthy meal plan for their respective diet. So this wasn’t a case of “any omnivorous diet vs healthy vegan diet”, but rather “healthy omnivorous diet vs healthy vegan diet”.

    Again, the paper itself has the full details—a short version is that it involved a healthy meal kit delivery service, followed by ongoing dietician involvement in an equal and carefully-controlled fashion.

    So, aside from that one group had an omnivorous meal plan and the other vegan, both groups received the same level of “healthy eating” support, guidance, and oversight.

    But isn’t [insert your preferred animal product here] healthy?

    Quite possibly! For general health, general scientific consensus is that eating at least mostly plants is best, red meat is bad, poultry is neutral in moderation, fish is good in moderation, dairy is good in moderation if fermented, eggs are good in moderation if not fried.

    This study looked at the various biomarkers of aging that we listed, and not every possible aspect of health—there’s more science yet to be done, and the researchers themselves are calling for it.

    It also bears mentioning that for some (relatively few, but not insignificantly few) people, extant health conditions may make a vegan diet unhealthy or otherwise untenable. Do speak with your own doctor and/or dietician if unsure.

    See also: Do We Need Animal Products To Be Healthy?

    We would hypothesize, by the way, that the anti-aging benefits of a vegan diet are probably proportional to abstention from animal products—meaning that even if you simply have some “vegan days”, while still consuming animal products other days, you’ll still get benefit for the days you abstained. That’s just our hypothesis though.

    Take care!
