GABA Against Stress/Anxiety

A Neurotransmitter Less Talked-About

GABA is taken by many people as a supplement, mostly as a mood modifier, though its health claims go beyond the recreational—and also, we’re of the opinion that mental health is also just health, and if it works, it works. We’ll explore some of the claims and science behind them today…

What is GABA?

GABA stands for gamma-aminobutyric acid, and it’s a neurotransmitter. It’s a lot less talked-about than for example dopamine or serotonin, but it’s very important nonetheless.

We make it ourselves inside our body, and we can also get it from our food, or supplement it, and some drugs will also have an effect on its presence and/or activity in our body.

What foods is it found in?

  • Animals, obviously (just like in human brains*)
  • Fermented foods (many kinds)
  • Yeast
  • Tea
  • Tomatoes
  • Mulberries

For more details, see:

γ-Aminobutyric acid found in fermented foods and beverages: current trends

*However, we do not recommend eating human brains, due to the risk of CJD and prion diseases in general.

What claims are made about it and are they true?

For brevity, we’ll give a little spoiler up-front: all the popular claims for it appear to be valid, though there’s definitely room for a lot more human trials (we skipped over a lot of rodent studies today!).

So we’ll just drop some of its main benefits, and human studies to back those.

Reduction of stress and anxiety

GABA decreases task-related stress and anxiety within 30 minutes of being taken, both in subjective measures (i.e., self-reports) and in objective clinical physiological measures:

Oral intake of γ-aminobutyric acid affects mood and activities of central nervous system during stressed condition induced by mental tasks

Cognitive enhancement

It’s not a does-everything nootropic like some, but it does have clear benefits to episodic memory:

❝GABA intake might help to distribute limited attentional resources more efficiently, and can specifically improve the identification and ordering of visual events that occur in close temporal succession

One of the things that makes this one important is that it also deals with the often-asked question of “does GABA pass the blood-brain barrier”:

❝The present findings do give further credence to the idea that oral ingestion does allow GABA to reach the brain and exert direct effects on cognition, which in the present case were specific to temporal attention.❞

Potential for more

We take care to give good quality sources, so the following study comes with a big caveat that it has since been retracted. Why was it retracted, you wonder?

It’s about the sample; they cite “30 healthy adults”, but neglected tp mention that this figure was initially 46. What happened to the other 16 participants is unclear, but given that this was challenged and the challenge not answered, it was sufficient for the journal (Nature) to pull the study, in case of deliberate sample bias.

However! Running the numbers in their results section, a probability of 0.03 is very compelling unless the disappearance of 16 subjects was outright fraudulent (which we regrettably cannot know either way).

Here’s the study (so take it with a pinch of salt, considering the above), and taken at face value, it shows how GABA supplementation improves accurate reactions to fast-moving visual and auditory stimuli:

RETRACTED ARTICLE: γ-Aminobutyric acid (GABA) administration improves action selection processes: a randomised controlled trial

…so, hopefully this experiment will be repeated, without disappearing participants!

The sweet spot

You may be wondering how something that slows a person down (having a relaxing effect) can also speed a person up. This has to do with what it is and isn’t affecting; think of it like a “focus mode” on your computer or other device that greys-out everything else a bit so that you can focus on what you’re doing.

It’s in some ways (by different neurochemical pathways, though) a similar effect to the “relaxed alertness” created by l-theanine supplementation.

There’s also a sweet spot whereby GABA is toning some things down just the right amount, without adversely affecting performance in areas we don’t want slowed down. For the science of this, see:

Too Little and Too Much: Hypoactivation and Disinhibition (Reduced GABAergic Inhibition) of Medial Prefrontal Cortex Cause Attentional Deficits

Is it safe?

GABA is “Generally Recognized As Safe”. However:

  • you should speak with your pharmacist if you are taking any medications for blood pressure or epilepsy, as GABA supplementation may cause them to work too well.
  • you should absolutely not take GABA with alcohol or opioids as (dose-dependent for all the substances involved, and also depending on your metabolic base rate and other factors) its acute depression of the CNS can mean you relax and slow down too much, and you may find yourself not breathing often enough to sustain life.

Aside from that, it is considered safe up to at least 1g/kg/day*. Given that popular doses are 120–750mg, and most people weigh more than 750g, this is very safe for most people:

  • How To Stay Alive (When You Really Don’t Want To)

    How To Stay Alive (When You Really Don’t Want To)

    A subscriber recently requested:

    ❝Request: more people need to be aware of suicidal tendencies and what they can do to ward them off❞

    …and we said we’d do that one of these Psychology Sundays, so here we are, doing it!

    First of all, we’ll mention that we did previously do a main feature on managing depression (in oneself or a loved one); here it is:

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

    Now, not all depression leads to suicidality, and not all suicide is pre-empted by depression, but there’s a large enough crossover that it seems sensible to put that article here, for anyone who might find it of use, or even just of interest.

    Now, onwards, to the specific, and very important, topic of suicide.

    This should go without saying, but some of today’s content may be a little heavy.

    We invite you to read it anyway if you’re able, because it’s important stuff that we all should know, and not talking about it is part of what allows it to kill people.

    So, let’s take a deep breath, and read on…

    The risk factors

    Top risk factors for suicide include:

    • Not talking about it
    • Having access to a firearm
    • Having a plan of specifically how to commit suicide
    • A lack of social support
    • Being male
    • Being over 40

    Now, some of these are interesting sociologically, but aren’t very useful practically; what a convenient world it’d be if we could all simply choose to be under 40, for instance.

    Some serve as alarm bells, such as “having a plan of specifically how to commit suicide”.

    If someone has a plan, that plan’s never going to disappear entirely, even if it’s set aside!

    (this writer is deeply aware of the specifics of how she has wanted to end things before, and has used the advice she gives in this article herself numerous times. So far so good, still alive to write about it!)

    Specific advices, therefore, include:

    Talk about it / Listen

    Depending on whether it’s you or someone else at risk:

    • Talk about it, if it’s you
    • Listen attentively, if it’s someone else

    There are two main objections that you might have at this point, so let’s look at those:

    “I have nobody to talk to”—it can certainly feel that way, sometimes, but you may be surprised who would listen if you gave them the chance. If you really can’t trust anyone around you, there are of course suicide hotlines (usually per area, so we’ll not try to list them here; a quick Internet search will get you what you need).

    If you’re worried it’ll result in bad legal/social consequences, check their confidentiality policy first:

    • Some hotlines can and will call the police, for instance.
    • Others deliberately have a set-up whereby they couldn’t even trace the call if they wanted to.
      • On the one hand, that means they can’t intervene
      • On the other hand, that means they’re a resource for anyone who will only trust a listener who can’t intervene.

    “But it is just a cry for help”—then that person deserves help. What some may call “attention-seeking” is, in effect, care-seeking. Listen, without judgement.

    Remove access to firearms, if applicable and possible

    Ideally, get rid of them (safely and responsibly, please).

    If you can’t bring yourself to do that, make them as inconvenient to get at as possible. Stored securely at your local gun club is better than at home, for example.

    If your/their plan isn’t firearm-related, but the thing in question can be similarly removed, remove it. You/they do not need that stockpile of pills, for instance.

    And of course you/they could get more, but the point is to make it less frictionless. The more necessary stopping points between thinking “I should just kill myself” and being able to actually do it, the better.

    Have/give social support

    What do the following people have in common?

    • A bullied teenager
    • A divorced 40-something who just lost a job
    • A lonely 70-something with no surviving family, and friends that are hard to visit

    Often, at least, the answer is: the absence of a good social support network

    So, it’s good to get one, and be part of some sort of community that’s meaningful to us. That could look different to a lot of people, for example:

    • A church, or other religious community, if we be religious
    • The LGBT+ community, or even just a part of it, if that fits for us
    • Any mutual-support oriented, we-have-this-shared-experience community, could be anything from AA to the VA.

    Some bonus ideas…

    If you can’t live for love, living for spite might suffice. Outlive your enemies; don’t give them the satisfaction.

    If you’re going to do it anyway, you might as well take the time to do some “bucket list” items first. After all, what do you have to lose? Feel free to add further bucket list items as they occur to you, of course. Because, why not? Before you know it, you’ve postponed your way into a rich and fulfilling life.

    Finally, some gems from Matt Haig’s “The Comfort Book”:
    • “The hardest question I have been asked is: “How do I stay alive for other people if I have no one?” The answer is that you stay alive for other versions of you. For the people you will meet, yes, but also the people you will be.”
    • “Stay for the person you will become”
    • “You are more than a bad day, or week, or month, or year, or even decade”
    • “It is better to let people down than to blow yourself up”
    • “Nothing is stronger than a small hope that doesn’t give up”
    • “You are here. And that is enough.”

    You can find Matt Haig’s excellent “The Comfort Book” on Amazon, as well as his more well-known book more specifically on the topic we’ve covered today, “Reasons To Stay Alive“.

  • The Tiniest Seeds With The Most Value

    If You’re Not Taking Chia, You’re Missing Out

    Last Tuesday, we wrote about nutritional psychiatry, and the benefits of eating for one’s mental health.

    You can check out Dr. Uma Naidoo’s to-dos, here:

    The 6 Pillars Of Nutritional Psychiatry

    In response, one of our subscribers wrote to mention:

    ❝Really interesting….just put chia seeds in my diet love them……taking the Drs advice.❞

    ~ Cindy, 10almonds subscriber

    And then! On Friday, our tip at the top of the newsletter was:

    Not sure how to incorporate chia seeds into your diet? It’s easier to want the benefits of their many brain-healthy (and otherwise-healthy, too) nutrients, than it is to know what to do with them necessarily, and not everyone enjoys seeds as a snack. So…

    When you cook rice, throw in a tablespoon of chia seeds too. The cooking process will soften them and they won’t be texturally any different than the rice, but the nutrients will be all there.

    They can also be thrown in with lentils, in the same fashion! Or oatmeal, when cooking it or making overnight oats.

    We’ll be honest, it was Cindy’s comment that prompted us to suggest it. But wait! There was more to come in response:

    ❝You had a teaser ..on Chia seed.would of liked a article on the benefits . I’ve just discovered Chia seeds…❞

    ~ Cindy, 10almonds subscriber

    So, Cindy, this one’s for you:

    Nutritional powerhouse

    First things first, these tiny seeds have a lot of nutrients. There are not many more nutrient-dense foods than this (there’s a kind of seaweed that might be a contender; we’ll have to do some research and get back to you).

    Check them out:

    USDA Nutritional Factsheet: Chia Seeds

    So much protein and healthy fat, so many vitamins and minerals, and so many miscellaneous other micronutrients that we’d be here all day to list them (which is why we linked the above factsheet instead).

    Antioxidants in abundance

    These deserve a special mention, because they include quercetin which we’ve written about previously:

    Fight Inflammation & Protect Your Brain, With Quercetin

    …as well as quite a collection of others (including chlorogenic acid and caffeic acid, which may sound alarming but are great for lowering your blood pressure and against inflammation, respectively):

    There are others too, with cardioprotective effects, liver-healthy effects, and anticancer properties:

    Regular 10almonds readers will know that “what’s good for the blood, is good for the brain” is a very good rule of thumb already, but their highomega-3 content makes them especially so:

  • Carrots vs Parsnips – 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 carrots to parsnips, we picked the parsnips.

    Why?

    There are arguments for both! But we say parsnips win on overall nutritional density.

    In terms of macros, parsnips vary quite a lot from region to another, but broadly speaking, parsnips have more carbs and fiber, and/but the ratios are such that carrots have the lower glycemic index. We’ll call this one a win for carrots.

    When it comes to vitamins, carrots have more of vitamins A, B2, B3, B6, and choline, while parsnips have more of vitamins B1, B5, B9, C, E, and K. A small win for parsnips here.

    In the category of minerals, carrots are not higher in any minerals, while parsnips are higher in calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. An overwhelming win for parsnips.

    While the overall vitamin and mineral content puts parsnips ahead, it’s still worth noting that carrots have highly bioavailable megadoses of vitamin A.

    Another thing to note is that the glycemic index recorded for both is when peeled and boiled, whereas both of these root vegetables can be enjoyed raw if you wish, which has a much lower GI.

    In short, enjoy either or both, but parsnips are the more nutritionally dense overall.

  • Burn! How To Boost Your Metabolism

    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.

    Let’s burn! Metabolic tweaks and hacks

    Our metabolism is, for as long as we live, a constantly moving thing. And it’s not a monolith either; there are parts of our metabolism that can speed up or slow down independently of others.

    If we talk about metabolism without clarifying context, though, this is usually about one’s “basal metabolic rate”, that is, how many calories we burn just by being alive.

    Why do we want to speed it up? Might we ever want to slow it down?

    We might want to slow our metabolism down in survival circumstances, but generally speaking, a faster metabolism is a better one.

    Yes, even when it comes to aging. Because although metabolism comes with metabolizing oxygen (which, ironically, tends to kill us eventually, since this is a key part of cellular aging), it is still beneficial to replace cells sooner rather than later. The later we replace a given cell (ie, the longer the cell lives), the more damaged it gets, and then the copy is damaged from the start, because the damage was copied along with it. So, best to have a fast metabolism to replace cells quickly when they are young and healthy.

    A quick metabolism helps the body to do this.

    Most people, of course, are interested in a fast metabolism to burn off fat, but beware: if you increase your metabolism without consideration to how and when you consume calories, you will simply end up eating more to compensate.

    One final quick note before we begin:

    Limitations

    There’s a lot we can do to change our metabolism, but there are some things that may be outside of our control. They include:

    • Age—we can influence our biological age, but we cannot (yet!) halt aging, so this will happen
    • Body size—and yes we can change this a bit, but we all have our own “basic frame” to work with. Someone who is 6’6” is never going to be able to have the same lower-end-of-scale body mass of someone who is 5’0”, say.
    • Sex—this is about hormones, and HRT is a thing, but for example, broadly speaking, men will have faster metabolisms than women, because of hormonal differences.
    • Medical conditions—often also related to other hormones, but for example someone with Type 1 Diabetes is going to have a very different relationship with their metabolism than someone without, and someone with a hypo- or hyperactive thyroid will again have a very different metabolism in a way that that lifestyle factors can’t completely compensate for.

    The tips and tricks

    Intermittent fasting

    Intermittent fasting has been found to, amongst other things, promote healthy apoptosis and autophagy (in other words: early programmed cell death and recycling—these are good things).

    It also has anti-inflammatory benefits and decreases the risk of insulin resistance. In other words, intermittent fasting boosts the metabolism while simultaneously guarding against some of the dangers of a faster metabolism (harms you’d get if you instead increased your metabolism by doing intense exercise and then eating a mountain of convenience food to compensate)

    Read the science: Intermittent Fasting: Is the Wait Worth the Weight?

    Read our prior article: Fasting Without Crashing? We Sort The Science From The Hype

    Enjoy plenty of protein

    This one won’t speed your metabolism up, so much as help it avoid slowing down as a result of fat loss.

    Because of our body’s marvelous homeostatic system trying to keep our body from changing status at any given time, often when we lose fat, our body drops our metabolism to compensate, thinking we are in an ongoing survival situation and food is scarce so we’d better conserve energy (as fat). That’s a pain for would-be weight-loss dieters!

    Eating protein can let our body know that we’re perfectly safe and not starving, so it will keep the metabolism ticking over nicely, without putting on fat.

    Read the science: The role of protein in weight loss and maintenance

    Stay hydrated

    People think of drinking water as part of a weight loss program being just about filling oneself up, and that is a thing, but it also has a role to play in our metabolism. Specifically, lipolysis (the process of removing fat).

    Because, we are mostly water. Not only is it the main content of our various body tissue cells, but also, of particular note, our blood (the means by which everything is transported around our body) is mostly water, too.

    It’s hard for the body to keep everything ticking over like a well-oiled machine if its means of transportation is sluggish!

    Check it out: Increased Hydration Can Be Associated with Weight Loss

    Take a stand

    That basal metabolic rate we talked about?

    • If you’re lying down at rest, that’s what your metabolism will be like.
    • If you’re sitting up, it’ll be a little quicker, but not much.
    • If you’re standing, suddenly half your body is doing things, and you don’t even notice them because they’re just stabilizing muscles and the like, but on a cellular level, your body gets very busy.

    Read all about it: Cardiometabolic impact of changing sitting, standing, and stepping in the workplace

    Time to invest in a standing desk? Or a treadmill in front of the TV?

    The spice of life

    Capsaicin, the compound in many kinds of pepper that give them their spicy flavor, boosts the metabolism. In the words of Tremblay et al for the International Journal of Obesity:

    ❝[Capsaicin] stimulates the sympathoadrenal system that mediates the thermogenic and anorexigenic effects of capsaicinoids.

    Capsaicinoids have been found to accentuate the impact of caloric restriction on body weight loss.

    Some studies have also shown that capsinoids increase energy expenditure.

    Capsaicin supplementation attenuates or even prevents the increase in hunger and decrease in fullness as well as the decrease in energy expenditure and fat oxidation, which normally result from energy restriction❞

    Read for yourself: Capsaicinoids: a spicy solution to the management of obesity?

    You snooze, you lose (fat)

    While exercising is generally touted as the road to weight loss, and certainly regular exercise does have a part to play, doing so without good rest will have bad results.

    In fact, even if you’re not exercising, if you don’t get enough sleep your metabolism will get sluggish to try to slow you down and encourage you to sleep.

    So, be proactive, and make getting enough good quality sleep a priority.

    Eat for metabolic health

  • The Lupus Solution – by Dr. Tiffany Caplan & Dr. Brent Caplan

    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.

    Lupus is not fun, and this book sets out to make it easier.

    Starting off by explaining the basics of autoimmunity and how lupus works, the authors go on the address the triggers of lupus and how to avoid them—which if you’ve been suffering from lupus for a while, you probably know this part already, but it’s as well to give them a look over just in case you missed something.

    The real value of the book though comes in the 8 chapters of the section “Tools & Therapies” which are mostly lifestyle adjustments though there are additionally some pharmaceutical approaches that can also help, and they are explained too. And no, it’s not just “reduce inflammation” (but yes, also that); rather, a whole array of things are examined that often aren’t thought of as related to lupus, but in fact can have a big impact.

    The style is to-the-point and informational, and formatted for ease of reading. It doesn’t convey more hard science than necessary, but it does have a fair bibliography at the back.

    It’s a short book, weighing in at 182 pages. If you want something more comprehensive, check out our review of The Lupus Encyclopedia, which is 848 pages of information-dense text and diagrams.

    Bottom line: if you have lupus and would like fewer symptoms, this book can help you with that quite a bit without getting so technical as the aforementioned encyclopedia.

  • Pistachios vs Brazil Nuts – 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 pistachios to Brazil nuts, we picked the pistachios.

    Why?

    In terms of macros, pistachios have more protein, carbs, and fiber, while Brazil nuts have more fat. The fats are mostly healthy, although it is worth noting that Brazil nuts have not only more total saturated fat, but also more saturated fat proportionally to total fats. All in all, Brazil nuts’ macro balance isn’t bad, but we say pistachios have it better.

    When it comes to vitamins, pistachios have a lot more of vitamins A, B1, B2, B3, B5, B6, B7, B9, and C, while Brazil nuts have more vitamin E. An easy win for pistachios here.

    In the category of minerals, it gets interesting: pistachios have more iron and potassium, while Brazil nuts have more calcium, copper, magnesium, phosphorus, selenium, and zinc. Sounds great, but… About that selenium:

    • A cup of cashews contains 38% of the RDA of selenium. This will go towards helping your hair be luscious and shiny (also important for energy conversion).
    • A cup of Brazil nuts contains 10,456% of the RDA of selenium. This is way past the point of selenium toxicity, and your (luscious, shiny) hair will fall out.

    For this reason, it’s recommended to eat no more than 3–4 Brazil nuts per day.

    We consider that a point against Brazil nuts.

    Adding up the sections gives us an overall win for pistachios. Of course, enjoy Brazil nuts too if you will, but in careful moderation please!
