The Magic of Mushrooms
“The Longevity Vitamin that’s not a vitamin” is a great tagline for what’s actually an antioxidant amino acid nutraceutical, but in this case, we’re not the ones spearheading its PR, but rather, the Journal of Nutritional Science:
Is ergothioneine a “longevity vitamin” limited in the American diet?
It can be found in all foods, to some extent, but usually in much tinier amounts than would be useful. The reason for this is that it’s synthesized by a variety of microbes (mostly fungi and actinobacteria), and enters the food chain via vegetables that are grown in soil that contain such (which is basically all soil, unless you were to go out of your way to sterilize it, or something really unusually happened).
About those fungi? That includes common popular edible fungi, where it is found quite generously. An 85g (3oz) portion of (most) mushrooms contains about 5mg of ergothioneine, the consumption of which is associated with a 16% reduced all-cause mortality:
However… Most Americans don’t eat that many mushrooms, and those polled averaged 1.1mg/day ergothioneine (in contrast with, for example, Italians’ 4.6mg/day average).
Antioxidant properties
While its antioxidant properties aren’t the most exciting quality, they are worth a mention, on account of their potency:
The biology of ergothioneine, an antioxidant nutraceutical
This is also part of its potential bid to get classified as a vitamin, because…
❝Decreased blood and/or plasma levels of ergothioneine have been observed in some diseases, suggesting that a deficiency could be relevant to the disease onset or progression❞

Healthy aging
Building on from the above, ergothioneine has been specifically identified as being associated with healthy aging and the prevention of cardiometabolic diseases:
❝An increasing body of evidence suggests ergothioneine may be an important dietary nutrient for the prevention of a variety of inflammatory and cardiometabolic diseases and ergothioneine has alternately been suggested as a vitamin, “longevity vitamin”, and nutraceutical❞
~ Dr. Bernadette Moore et al., citing more references every few words there

Good for the heart = good for the brain
As a general rule of thumb, “what’s good for the heart is good for the brain” is almost always true, and it appears to be so in this case, too:
❝Ergothioneine crosses the blood–brain barrier and has been reported to have beneficial effects in the brain. In this study, we discuss the cytoprotective and neuroprotective properties of ergotheioneine, which may be harnessed for combating neurodegeneration and decline during aging.❞

What immunocompromised people want you to know
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.
While many people in the U.S. have abandoned COVID-19 mitigations like vaccines and masking, the virus remains dangerous for everyone, and some groups face higher risks than others. Immunocompromised people—whose immune systems don’t work as well as they should due to health conditions or medications—are more vulnerable to infection and severe symptoms from the virus.
Public Good News spoke with three immunocompromised people about the steps they take to protect themselves and what they want others to know about caring for each other.
[Editor’s note: The contents of these interviews have been condensed for length.]
PGN: What measures have you been taking to protect yourself since the COVID-19 pandemic began?
Tatum Spears, Virginia
From less than a year old, I had serious, chronic infections and have missed huge chunks of my life. In 2020, I quit my public job, and I have not worked publicly since.
I have a degree in vocal performance and have been singing my whole life, but I haven’t performed publicly since 2019. I feel like a bird without wings. I had to stop traveling. Since no one wears a mask anymore, I can’t go to the movies or social outings or any party.
All my friends live in my phone now. It’s a community of people—a lot of them are immunocompromised or disabled in some way.
There are a good portion of them who just take COVID-19 seriously and want to protect their health, who feel the existential abandonment and the burden of all of this. It’s really isolating having to step back from any sort of social life. I have to assess my risk every single time I leave the house.
Gwendolyn Alyse Bishop, Washington
I was hit by a car when I was very young. I woke up from surgery, and doctors told me I had lost almost all of my spleen. So, I was always the sickest kid in my school.
When COVID-19 hit, I started working from home. At first, I wore cloth masks. I didn’t really learn about KN95 masks until right around the time that COVID-19 disabled me. [Editor’s note: N95 and KN95 masks have been shown to be significantly more effective at preventing the transmission of viral particles than cloth masks.]
I actually don’t get out much anymore because I am disabled by long COVID now, but when I do leave, I wear a respirator in all shared air spaces. My roommate and I have HEPA filters going in every room.And then we test. I have a Pluslife testing dock, and so we keep a weekly testing schedule with that and then test if there are any symptoms. I got reinfected [with COVID-19] last winter, and a Pluslife test helped me catch it early and get Paxlovid. [Editor’s note: Pluslife is a brand of an at-home COVID-19 nucleic acid amplification test, which has been shown to be significantly more effective at detecting COVID-19 than at-home antigen rapid tests.]
Abby Mahler, California
I have lupus, and in 2016, I started taking the drug hydroxychloroquine, which is an immunomodulator. I’m not as immunocompromised as some people, but I certainly don’t have a normal immune system, which has resulted in long-term infections like C. diff.I started masking early. My roommates and I prioritize going outside. We don’t remove our masks inside in public places.
We are in a pod with one other household, and the pod has agreements on the way that we interact with public space. So, we will only unmask with people who have tested ahead of time. We use Metrix, an at-home nucleic acid amplification test.
While it’s not easy and it’s not the life that we had prior to COVID-19’s existence, it is a life that has provided us quite a lot of freedom, in the sense that we are not sick all the time. We are conscientiously making decisions that allow us to have a nice time without a monkey on our backs, which is freeing.
PGN: What do you want people who are not immunocompromised to know?
T.S.: Don’t be afraid to be the only person in a room wearing a mask. Your own health is worth it. And you have to realize how callous [people who don’t wear a mask are] by existing in spaces and breathing [their] air [on immunocompromised people].
People think that vaccines are magic, but vaccines alone are not enough. I would encourage people to look at the Swiss cheese model of risk assessment.
Each slice of Swiss cheese has holes in it in different places, and each layer represents a layer of virus mitigation. One layer is vaccines. Another layer is masks. Then there’s staying home when you’re sick and testing.
G.A.B.: I wish people were masking. I wish people understood how likely it is that they are also now immunocompromised and vulnerable because of the widespread immune dysregulation that COVID-19 is causing. [Editor’s note: Research shows that COVID-19 infections may cause long-term harm to the immune system in some people.]
I want people to be invested in being good community members, and part of that is understanding that COVID-19 hits the poorest the hardest—gig workers, underpaid employees, frontline service workers, people who were already disabled or immunocompromised.
If people want to be good community members, they not only need to protect immunocompromised and disabled people by wearing a mask when they leave their homes, but they also need to actually start taking care of their community members and participating in mutual aid. [Editor’s note: Mutual aid is the exchange of resources and services within a community, such as people sharing extra N95 masks.]
I spend pretty much all of my time working on LongCOVIDAidBot, which promotes mutual aid for people who have been harmed by COVID-19.
A.M.: An important thing to think about when you’re not disabled is that it becomes a state of being for all people, if they’re lucky. You will become disabled, or you will die.
It is a privilege, in my opinion, to become disabled because I can learn different ways of living my life. And being able to see yourself as a body that changes over time, I hope, opens up a way of looking at your body as the porous reality that it is.
Some people think of themselves as being willing to make concessions or change their behavior when immunocompromised people are around, but you don’t always know when someone is immunocompromised.
So, if you’re not willing to change the way that you think about yourself as a person who is susceptible [to illness], then you should change the way that you consider other people around you. Wearing a mask—at the very least in public indoor spaces—means considering the unknown realities of all the people who are interacting with that space.

The Dopamine Precursor And More
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.
What Is This Supplement “NALT”?
N-Acetyl L-Tyrosine (NALT) is a form of tyrosine, an amino acid that the body uses to build other things. What other things, you ask?
Well, like most amino acids, it can be used to make proteins. But most importantly and excitingly, the body uses it to make a collection of neurotransmitters—including dopamine and norepinephrine!
- Dopamine you’ll probably remember as “the reward chemical” or perhaps “the motivation molecule”
- Norepinephrine, also called noradrenaline, is what powers us up when we need a burst of energy.
Both of these things tend to get depleted under stressful conditions, and sometimes the body can need a bit of help replenishing them.
What does the science say?
This is Research Review Monday, after all, so let’s review some research! We’re going to dive into what we think is a very illustrative study:
A 2015 team of researchers wanted to know whether tyrosine (in the form of NALT) could be used as a cognitive enhancer to give a boost in adverse situations (times of stress, for example).
They noted:
❝The potential of using tyrosine supplementation to treat clinical disorders seems limited and its benefits are likely determined by the presence and extent of impaired neurotransmitter function and synthesis.❞
More on this later, but first, the positive that they also found:
❝In contrast, tyrosine does seem to effectively enhance cognitive performance, particularly in short-term stressful and/or cognitively demanding situations. We conclude that tyrosine is an effective enhancer of cognition, but only when neurotransmitter function is intact and dopamine and/or norepinephrine is temporarily depleted❞
That “but only”, is actually good too, by the way!
You do not want too much dopamine (that could cause addiction and/or psychosis) or too much norepinephrine (that could cause hypertension and/or heart attacks). You want just the right amount!
So it’s good that NALT says “hey, if you need some more, it’s here, if not, no worries, I’m not going to overload you with this”.
Read the study: Effect of tyrosine supplementation on clinical and healthy populations under stress or cognitive demands
About that limitation…
Remember they said that it seemed unlikely to help in treating clinical disorders with impaired neurotransmitter function and/or synthesis?
Imagine that you employ a chef in a restaurant, and they can’t keep up with the demand, and consequently some of the diners aren’t getting fed. Can you fix this by supplying the chef with more ingredients?
Well, yes, if and only if the problem is “the chef wasn’t given enough ingredients”. If the problem is that the oven (or the chef’s wrist) is broken, more ingredients aren’t going to help at all—something different is needed in those cases.
So it is with, for example, many cases of depression.
See for example: Tyrosine for depression: a double-blind trial
About blood pressure…
You may be wondering, “if NALT is a precursor of norepinephrine, a vasoconstrictor, will this increase my blood pressure adversely?”
Well, check with your doctor as your own situation may vary, but under normal circumstances, no. The effect of NALT is adaptogenic, meaning that it can help keep its relevant neurotransmitters at healthy levels—not too low or high.
See what we mean, for example in this study where it actually helped keep blood pressure down while improving cognitive performance under stress:
Effect of tyrosine on cognitive function and blood pressure under stress
Bottom line:
For most people, NALT is a safe and helpful way to help keep healthy levels of dopamine and norepinephrine during times of stress, giving cognitive benefits along the way.

Magnesium Glycinate vs Magnesium Citrate – 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 magnesium glycinate to magnesium citrate, we picked the citrate.
Why?
Both are fine sources of magnesium, a nutrient in which it’s very common to be deficient—a lot of people don’t eat many leafy greens, beans, nuts, and so forth that contain it.
A quick word on a third contender we didn’t include here: magnesium oxide is probably the most widely-sold magnesium supplement because it’s cheapest to make. It also has woeful bioavailability, to the point that there seems to be negligible benefit to taking it. So we don’t recommend that.
Magnesium glycinate and magnesium citrate are both absorbed well, but magnesium citrate is the most well-absorbed form of magnesium supplement.
In terms of the relative merits of the glycine or the citric acid (the “other part” of magnesium glycinate and magnesium citrate, respectively), both are also great nutrients, but the amount delivered with the magnesium is quite small in each case, and so there’s nothing here to swing it one way or the other.
For this reason, we went with the magnesium citrate, as the most readily bioavailable!

ADHD… As An Adult?
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.
ADHD—not just for kids!
Consider the following:
- If a kid has consistent problems paying attention, it’s easy and common to say “Aha, ADHD!”
- If a young adult has consistent problems paying attention, it’s easy and common to say “Aha, a disinterested ne’er-do-well!”
- If an older adult has consistent problems paying attention, it’s easy and common to say “Aha, a senior moment!”
Yet, if we recognize that ADHD is fundamentally a brain difference in children (and we do; there are physiological characteristics that we can test), and we can recognize that as people get older our brains typically have less neuroplasticity (ability to change) than when we are younger rather than less, then… Surely, there are just as many adults with ADHD as kids!
After all, that rather goes with the linear nature of time and the progressive nature of getting older.
So why do kids get diagnoses so much more often than adults?
Parents—and schools—can find children’s ADHD challenging, and it’s their problem, so they look for an explanation, and ADHD isn’t too difficult to find as a diagnosis.
Meanwhile, adults with ADHD have usually developed coping mechanisms, have learned to mask and/or compensate for their symptoms, and we expect adults to manage their own problems, so nobody’s rushing to find an explanation on their behalf.
Additionally, the stigma of neurodivergence—especially something popularly associated with children—isn’t something that many adults will want for themselves.
But, if you have an ADHD brain, then recognizing that (even if just privately to yourself) can open the door to much better management of your symptoms… and your life.
So what does ADHD look like in adults?
ADHD involves a spread of symptoms, and not everyone will have them all, or have them in the same magnitude. However, very commonly most noticeable traits include:
- Lack of focus (ease of distraction)
- Conversely: high focus (on the wrong things)
- To illustrate: someone with ADHD might set out to quickly tidy the sock drawer, and end up Marie Kondo-ing their entire wardrobe… when they were supposed to doing something else
- Conversely: high focus (on the wrong things)
- Poor time management (especially: tendency to procrastinate)
- Forgetfulness (of various kinds—for example, forgetting information, and forgetting to do things)

Wait, where’s the hyperactivity in this Attention Deficit Hyperactivity Disorder?
It’s often not there. ADHD is simply badly-named. This stems from how a lot of mental health issues are considered by society in terms of how much they affect (and are observable by) other people. Since ADHD was originally noticed in children (in fact being originally called “Hyperkinetic Reaction of Childhood”), it ended up being something like:
“Oh, your brain has an inconvenient relationship with dopamine and you are driven to try to correct that by shifting attention from boring things to stimulating things? You might have trouble-sitting-still disorder”
Hmm, this sounds like me (or my loved one); what to do now at the age of __?
Some things to consider:
- If you don’t want medication (there are pros and cons, beyond the scope of today’s article), you might consider an official diagnosis not worth pursuing. That’s fine if so, because…
- More important than whether or not you meet certain diagnostic criteria, is whether or not the strategies recommended for it might help you.
- Whether or not you talk to other people about it is entirely up to you. Maybe it’s a stigma you’d rather avoid… Or maybe it’ll help those around you to better understand and support you.
- Either way, you might want to learn more about ADHD in adults. Today’s article was about recognizing it—we’ll write more about managing it another time!
In the meantime… We recommended a great book about this a couple of weeks ago; you might want to check it out:

Sarah Raven’s Garden Cookbook – by Sarah Raven
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.
Note: the US Amazon site currently (incorrectly) lists the author as “Jonathan Buckley”. The Canadian, British, and Australian sites all list the author correctly as Sarah Raven, and some (correctly) credit Jonathan Buckley as the photographer she used.
First, what it’s not: a gardening book. Beyond a few helpful tips, pointers, and “plant here, harvest here” instructions, this book assumes you are already capable of growing your own vegetables.
She does assume you are in a temperate climate, so if you are not, this might not be the book for you. Although! The recipes are still great; it’s just you’d have to shop for the ingredients and they probably won’t be fresh local produce for the exact same reason that you didn’t grow them.
If you are in a temperate climate though, this will take you through the year of seasonal produce (if you’re in a temperate climate but it’s in for example Australia, you’ll need to make a six-month adjustment for being in the S. Hemisphere), with many recipes to use not just one ingredient from your garden at a time, but a whole assortment, consistent with the season.
About the recipes: they (which are 450 in number) are (as you might imagine) very plant-forward, but they’re generally not vegan and often not vegetarian. So, don’t expect that you’ll produce everything yourself—just most of the ingredients!
Bottom line: if you like cooking, and are excited by the idea of growing your own food but are unsure how regularly you can integrate that, this book will keep you happily busy for a very long time.

Why is toddler milk so popular? Follow the money
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.
Toddler milk is popular and becoming more so. Just over a third of Australian toddlers drink it. Parents spend hundreds of millions of dollars on it globally. Around the world, toddler milk makes up nearly half of total formula milk sales, with a 200% growth since 2005. Growth is expected to continue.
We’re concerned about the growing popularity of toddler milk – about its nutritional content, cost, how it’s marketed, and about the impact on the health and feeding of young children. Some of us voiced our concerns on the ABC’s 7.30 program recently.
But what’s in toddler milk? How does it compare to cow’s milk? How did it become so popular?
What is toddler milk? Is it healthy?
Toddler milk is marketed as appropriate for children aged one to three years. This ultra-processed food contains:
- skim milk powder (cow, soy or goat)
- vegetable oil
- sugars (including added sugars)
- emulsifiers (to help bind the ingredients and improve the texture)
added vitamins and minerals.
Toddler milk is usually lower in calcium and protein, and higher in sugar and calories than regular cow’s milk. Depending on the brand, a serve of toddler milk can contain as much sugar as a soft drink.
Even though toddler milks have added vitamins and minerals, these are found in and better absorbed from regular foods and breastmilk. Toddlers do not need the level of nutrients found in these products if they are eating a varied diet.
Global health authorities, including the World Health Organization (WHO), and Australia’s National Health and Medical Research Council, do not recommend toddler milk for healthy toddlers.
Some children with specific metabolic or dietary medical problems might need tailored alternatives to cow’s milk. However, these products generally are not toddler milks and would be a specific product prescribed by a health-care provider.
Toddler milk is also up to four to five times more expensive than regular cow’s milk. “Premium” toddler milk (the same product, with higher levels of vitamins and minerals) is more expensive.
With the cost-of-living crisis, this means families might choose to go without other essentials to afford toddler milk.
Toddler milk is more expensive than cow’s milk and contains more sugar.
Dragana Gordic/ShutterstockHow toddler milk was invented
Toddler milk was created so infant formula companies could get around rules preventing them from advertising their infant formula.
When manufacturers claim benefits of their toddler milk, many parents assume these claimed benefits apply to infant formula (known as cross-promotion). In other words, marketing toddler milks also boosts interest in their infant formula.
Manufacturers also create brand loyalty and recognition by making the labels of their toddler milk look similar to their infant formula. For parents who used infant formula, toddler milk is positioned as the next stage in feeding.
How toddler milk became so popular
Toddler milk is heavily marketed. Parents are told toddler milk is healthy and provides extra nutrition. Marketing tells parents it will benefit their child’s growth and development, their brain function and their immune system.
Toddler milk is also presented as a solution to fussy eating, which is common in toddlers.
However, regularly drinking toddler milk could increase the risk of fussiness as it reduces opportunities for toddlers to try new foods. It’s also sweet, needs no chewing, and essentially displaces energy and nutrients that whole foods provide.
Toddler milk is said to help fussy eating, but it may make things worse.
zlikovec/ShutterstockGrowing concern
The WHO, along with public health academics, has been raising concerns about the marketing of toddler milk for years.
In Australia, moves to curb how toddler milk is promoted have gone nowhere. Toddler milk is in a category of foods that are allowed to be fortified (to have vitamins and minerals added), with no marketing restrictions. The Australian Competition & Consumer Commission also has concerns about the rise of toddler milk marketing. Despite this, there is no change in how it’s regulated.
This is in contrast to voluntary marketing restrictions in Australia for infant formula.
What needs to happen?
There is enough evidence to show the marketing of commercial milk formula, including toddler milk, influences parents and undermines child health.
So governments need to act to protect parents from this marketing, and to put child health over profits.
Public health authorities and advocates, including us, are calling for the restriction of marketing (not selling) of all formula products for infants and toddlers from birth through to age three years.
Ideally, this would be mandatory, government-enforced marketing restrictions as opposed to industry self-regulation in place currently for infant formulas.
We musn’t blame parents
Toddlers are eating more processed foods (including toddler milk) than ever because time-poor parents are seeking a convenient option to ensure their child is getting adequate nutrition.
Formula manufacturers have used this information, and created a demand for an unnecessary product.
Parents want to do the best for their toddlers, but they need to know the marketing behind toddler milks is misleading.
Toddler milk is an unnecessary, unhealthy, expensive product. Toddlers just need whole foods and breastmilk, and/or cow’s milk or a non-dairy, milk alternative.
If parents are worried about their child’s eating, they should see a health-care professional.
