Mushrooms vs Eggplant – Which is Healthier?

Our Verdict
When comparing mushrooms to eggplant, we picked the mushrooms.
Why?
First, you may be wondering: which mushrooms? Button mushrooms? White mushrooms? Chestnut mushrooms? Portobello mushrooms? And the answer is yes. Those (and more; it represents most mushrooms that are commonly sold fresh in western supermarkets) are all the same species at different ages; namely, Agaricus bisporus—not to be mistaken for fly agaric, which despite the name, is not even a member of the Agaricus genus, and is in fact Amanita muscari. This is an important distinction, because fly agaric is poisonous, though fatality is rare, and it’s commonly enjoyed recreationally (after some preparation, which reduces its toxicity) for its psychoactive effects. It’s the famous red one with white spots. Anyway, today we will be talking instead about Agaricus bisporus, which is most popular western varieties of “edible mushroom”.
With that in mind, let’s get down to it:
In terms of macros, mushrooms contain more than 3x the protein, while eggplant contains nearly 2x the carbs and 3x the fiber. We’ll call this a tie for macros.
As for vitamins, mushrooms contain more of vitamins B1, B2, B3, B5, B6, B7, B9, B12, D, and choline, while eggplant contains more of vitamins A, E, and K. Most notably for vegans, mushrooms are a good non-animal source of vitamins B12 and D, which nutrients are not generally found in plants. Mushrooms, of course, are not technically plants. In any case, the vitamins category is an easy win for mushrooms.
When it comes to minerals, mushrooms have more copper, iron, phosphorus, potassium, selenium, and zinc, while eggplant has more calcium, magnesium, and manganese. Another easy win for mushrooms.
One final thing worth noting is that mushrooms are a rich source of the amino acid ergothioneine, which has been called a “longevity vitamin” for its healthspan-increasing effects (see our article below).
Meanwhile, in the category of mushrooms vs eggplant, mushrooms don’t leave much room for doubt and are the clear winner here.

How To Clean Your Brain (Glymphatic Health Primer)

That’s not a typo! The name “glymphatic system” was coined by the Danish neuroscientist Dr. Maiken Nedergaard, and is a nod to its use of glial cells to do a similar job to that of the peripheral lymphatic system—but this time, in the CNS. Today, we have Dr. Jin Sung to tell us more:
Brainwashing (but not like that)
The glymphatic system may sound like a boring job, but so does “sanitation worker” in a city—yet the city would grind to a messy halt very very quickly without them. Same goes for your brain.
Diseases that are prevalent when this doesn’t happen the way it should include Alzheimer’s (beta-amyloid clearance) and Parkinson’s (alpha-synuclein clearance) amongst others.
Things Dr. Sung recommends for optimal glymphatic function include: sleep (7–9 hours), exercise (30–45 minutes daily), hydration (half your bodyweight in pounds, in ounces, so if your body weighs 150 lbs, that means 75 oz of water), good posture (including the use of good ergonomics, e.g. computer monitor at right height, car seat correct, etc), stress reduction (reduces inflammatory cytokines), getting enough omega-3 (the brain needs certain fats to work properly, and this is the one most likely to see a deficit), vagal stimulation (methods include humming, gargling, and gagging—please note we said vagal stimulation; easy to misread at a glance!), LED light therapy, and fasting (intermittent or prolonged).

How Metformin Slows Aging

Metformin And How It Slows Down Aging
That’s a bold claim for a title, but the scientific consensus is clear, and this Research Review Monday we’re going to take a look at exactly that!
Metformin is a common diabetes-management drug, used to lower blood sugar levels in people who either don’t have enough insulin or the insulin isn’t being recognized well enough by the body.
However, it also slows aging, which is a quality it’s also been studied for for more than a decade. We’ll look at some of the more recent research, though. Let’s kick off with an initial broad statement, from the paper “The Use of Metformin to Increase the Human Healthspan”, as part of the “Advances in Experimental Medicine and Biology” series:
In recent years, more attention has been paid to the possibility of using metformin as an anti-aging drug. It was shown to significantly increase the lifespan in some model organisms and delay the onset of age-associated declines. Growing amounts of evidence from clinical trials suggest that metformin can effectively reduce the risk of many age-related diseases and conditions, including cardiometabolic disorders, neurodegeneration, chronic inflammation and frailty.
How does it work?
That’s still being studied, but the scientific consensus is that it works by inducing hormesis—the process by which minor stress signals cells to start repairing themselves. How does it induce that hormesis? Again, still being studied, but it appears to do it by activating a specific enzyme; namely, the AMP-activated protein kinase:
Read: Metformin-enhances resilience via hormesis
It also has been found to slow aging by means of an anti-inflammatory effect, as a bonus!
Any bad news?
Well, firstly, in most places it’s only prescribed for diabetes management, not for healthy life extension. A lot of anti-aging enthusiasts have turned to the grey market online to get it, and we can’t recommend that.
Secondly, it does have some limitations:
- Its bioavailability isn’t great in tablet form (the form in which it is most commonly given)
- It has quite a short elimination half-life (around 6 hours), which makes it great to fix transient hyperglycemia in diabetics—job done and it’s out—but presents a logistical challenge when it comes to something so pernicious as aging.
- Some people are non-responders (a non-responder, in medicine, is someone for whom a drug simply doesn’t work, for no obvious reason)

No-Exercise Exercise!
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.
Do you love to go to the gym?
If so, today’s article might not be for you so much. Or maybe it will, because let’s face it, exercise is fun!
At least… It can be, and should be 😎
So without further ado, here’s a slew of no-exercise exercise ideas; we’re willing to bet that somewhere in the list there’s at least some you haven’t tried before, and probably some you haven’t done in a while but might enjoy making a reprise!
Walking
No surprises here: walking is great. Hopefully you have some green spaces near you, but if you don’t, [almost] any walking is better than no walking. So unless there’s some sort of environmental disaster going on outside, lace up and get stepping.
If you struggle to “walk for walking’s sake” give yourself a little mission. Walk to the shop to buy one item. Walk to the park and find a flower to photograph. Walk to the library and take out a book. Whatever works for you!

Take the stairs
This one doesn’t need many words, just: make it a habit.
Treat the elevators as though they aren’t there!

Dance
Dance is amazing! Any kind of dance, whatever suits your tastes. This writer loves salsa and tango, but no matter whether for you it’s zouk or zumba, breakdancing or line dancing, whatever gets you moving is going to be great for you.
If you don’t know how, online tutorials abound, and best of all is to attend local classes if you can, because they’re always a fun social experience too.
Make music
Not something often thought of as an exercise, but it is! Most instruments require that we be standing or siting with good posture, focusing intently on our movements, and often as not, breathing very mindfully too. And yes, it’s great for the brain as well!
Check out: This Is Your Brain on Music: The Science of a Human Obsession – by Dr. Daniel Levitin
Take a stand
If you spend a lot of time at a desk, please consider investing in a standing desk; they can be truly life-changing. Not only is it so much better for your back, hips, neck, and internal organs, but also it burns hundreds more calories than sitting, due to the no-exercise exercise that is keeping your body constantly stabilized while on your feet.
(or, if you’re like this writer: on your foot. I do have two feet, I just spend an inordinate amount of time at my desk standing on one leg at a time; I’m a bit of a flamingo like that)

Sit, but…
Sit in a sitting squat! Sometimes called a Slav squat, or an Asian squat, or a resting squat, or various other names:

Alternatively, sitting in seiza (the traditional Japanese sitting position) is also excellent, but watch out! While it’s great once your body is accustomed to it, if you haven’t previously sat this way much, you may cut off your own circulation, hurt your knees, and (temporarily) lose feeling in your feet. So if you don’t already sit in seiza often, gradually work up the time period you spend sitting in seiza, so that your vasculature can adapt and improve, which honestly, is a very good thing for your legs and feet to have.
Breathe
Perhaps the absolute most “no-exercise exercise” there is. And yes, of course you are (hopefully) breathing all the time, but how you are breathing matters a lot:

Clean
This doesn’t have to mean scrubbing floors like a sailor—even merely giving your house the Marie Kondo treatment counts, because while you’re distracted with all the objects, you’re going to be going back and forth, getting up and down, etc, clocking up lots of exercise that you barely even notice!
PS, check out: The Life-Changing Manga Of Tidying Up – by Marie Kondo
Garden
As with the above, it’s lots of activity that doesn’t necessarily feel like it (assuming you’re doing more pruning and weeding etc, and less digging ditches etc), and as a bonus, there are a stack of mental health benefits to being in a green natural environment and interacting with soil:

Climb
Depending on where you live, this might mean an indoor climbing wall, but give it a go! They have color-coded climbs from beginner to advanced, so don’t worry about being out of your depth.
And the best thing is, the beginner climbs will be as much a workout to a beginner as the advanced climbs will be to an advanced climber, because at the end of the day, you’re still clinging on for dear life, no matter whether it’s a sizeable handhold not far from the ground, or the impression of a fingernail crack in an overhang 100ft in the air.
Video games (but…)
Less in the category of Stardew Valley, and more in the category of Wii Fit.
So, dust off that old controller (or treat yourself to one if you didn’t have one already), and get doing a hundred sports and other physical activities in the comfort of your living room, with a surprisingly addictive gaming system!
Sex!
You probably don’t need instructions here, and if you do, well honestly, we’re running out of space today. But the answer to “does xyz count?” is “did it get your heart racing?” because if so, it counts
Take care!

It Didn’t Start with You – by Mark Wolynn

There is a trend in psychology to “blame the parents” for “childhood trauma” that can result in problems later in life. Sometimes fairly, sometimes not. This book’s mostly not about that.
It does touch on our own childhood trauma, if applicable. But mostly, it’s about epigenetic trauma inheritance. In other words, not just trauma that’s passed on in terms of “the cycle of abuse”, but trauma that’s passed on in terms of “this generation experienced trauma x, developed trauma response y, encoded it epigenetically, and passed it on to their offspring”.
So, how does one heal from a trauma one never directly experienced, and just inherited the response to it? That’s what most of this book is about, after establishing how epigenetic trauma inheritance works.
The author, a therapist, provides practical advice for how to do the things that can be done to rewrite the epigenetic code we inherited. Better late than never!
Bottom line: it is well-established that trauma is inheritable. But unlike one’s eye color or the ability to smell asparagus metabolites in urine, we can rewrite epigenetic things, to a degree. This book explains how.

Who Screens The Sunscreens?
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.
We Screen The Sunscreens!
Yesterday, we asked you what your sunscreen policy was, and got a spread of answers. Apparently this one was quite polarizing!
One subscriber who voted for “Sunscreen is essential to protect us against skin aging and cancer” wrote:
❝My mom died of complications from melanoma, so we are vigilant about sun and sunscreen. We are a family of campers and hikers and gardeners—outdoors in all seasons—and we never burn❞
Our condolences with regard to your mom! Life is so precious, and when something like that happens, it tends to stick with us. We’re glad you and your family are taking care of yourselves.
Of the subscribers who voted for “I put some on if I think I might otherwise get sunburned”, about half wrote to express uncertainties:
- uncertainty about how safe it is, and
- uncertainty about how helpful it is
…so we’re going to tackle those questions in a moment. But what of those who voted for “Sunscreen is full of harmful chemicals that can cause cancer”?
Of those, only one wrote a message, which was to say one has to be very careful of what is in the formula.
Let’s take a look, then…
Sunscreen is full of harmful chemicals that can cause cancer: True or False?
False—according to current best science. Research is ongoing!
There are four main chemicals (found in most sunscreens) that people tend to worry about:
- Abobenzone
- Oxybenzone
- Octocrylene
- Ecamsule
Now, these two sound like four brands of rocket fuel, but then, dihydrogen monoxide (DHMO), which is also found in most sunscreens, sounds like a deadly toxin too. That’s water, by the way.
But what of these four chemicals? Well, as we say, research is ongoing, but we found a study that measured all four, to see how much got into the blood, and what adverse effects, if any, this caused.
We’ll skip to their conclusion:
❝In this preliminary study involving healthy volunteers, application of 4 commercially available sunscreens under maximal use conditions resulted in plasma concentrations that exceeded the threshold established by the FDA for potentially waiving some nonclinical toxicology studies for sunscreens. The systemic absorption of sunscreen ingredients supports the need for further studies to determine the clinical significance of these findings. These results do not indicate that individuals should refrain from the use of sunscreen.❞
Now, “exceeded the threshold established by the FDA for potentially waiving some nonclinical toxicology studies for sunscreens” sounds alarming, so why did they close with the words “These results do not indicate that individuals should refrain from the use of sunscreen”?
Let’s skip back up to a line from the results:
❝The most common adverse event was rash, which developed in 1 participant with each sunscreen.❞
This was most probably due to the oxybenzone, which can cause allergic skin reactions in some people.
Let us take a moment to remember the most common adverse event that occurs from not wearing sunscreen: sunburn!
You can read the full study here:
None of those ingredients have been found to be carcinogenic, even at the maximal blood plasma concentrations studied, from applications 4x/day to 75% of the body.
UVA rays, on the other hand, are absolutely very much known to cause cancer, and the effect is cumulative.
Sunscreen is essential to protect us against skin aging and cancer: True or False?
True, unequivocally, unless we live indoors and/or otherwise never go about under sunlight.
“But our ancestors—” lived under the same sun we do, and either used sunscreen or got advanced skin aging and cancer.
Sunscreen of times past ranged from mud to mineral lotions, but it’s pretty much always existed. Even non-human animals that have skin and don’t have fur or feathers, tend to take mud-baths in sunny parts of the world.
If you’d like to avoid oxybenzone and other chemicals, though, you might have your reasons. Maybe you’re allergic, or maybe you read that it’s a potential endocrine disruptor with estrogen-like and anti-androgenic properties that you don’t want.
There are other options, to include physical blockers containing zinc and titanium dioxide, which are generally recognized as safe and effective ingredients.
If you’re interested, you can even make your own sunscreen that blocks both UVA and UVB rays (UVA is what causes skin cancer; UVB is “milder” and is what causes sunburn):

It’s Not Fantastic To Be Plastic

We Are Such Stuff As Bottles Are Made Of
We’ve written before about PFAS, often found in non-stick coatings and the like:
PFAS Exposure & Cancer: The Numbers Are High
Today we’re going to be talking about microplastics & nanoplastics!
What are microplastics and nanoplastics?
Firstly, they’renot just the now-banned plastic microbeads that have seen some use is toiletries (although those are classified as microplastics too).
Many are much smaller than that, and if they get smaller than a thousandth of a millimeter, then they get the additional classification of “nanoplastic”.
In other words: not something that can be filtered even if you were to use a single-micron filter. The microplastics would still get through, for example:
Scientists find about a quarter million invisible nanoplastic particles in a liter of bottled water
And unfortunately, that’s bad:
❝What’s disturbing is that small particles can appear in different organs and may cross membranes that they aren’t meant to cross, such as the blood-brain barrier❞
Note: they’re crossing the same blood-brain barrier that many of our nutrients and neurochemicals are too big to cross.
These microplastics are also being found in arterial plaque
What makes arterial plaque bad for the health is precisely its plasticity (the arterial walls themselves are elastic), so you most certainly do not want actual plastic being used as part of the cement that shouldn’t even be lining your arteries in the first place:
Microplastics found in artery plaque linked with higher risk of heart attack, stroke and death
❝In this study, patients with carotid artery plaque in which MNPs were detected had a higher risk of a composite of myocardial infarction, stroke, or death from any cause at 34 months of follow-up than those in whom MNPs were not detected❞
~ Dr. Raffaele Marfella et al.
(MNP = Micro/Nanoplastics)

We don’t know how bad this is yet
There are various ways this might not be as bad as it looks (the results may not be repeated, the samples could have been compromised, etc), but also, perhaps cynically but nevertheless honestly, it could also be worse than we know yet—only more experiments being done will tell us which.
In the meantime, here’s a rundown of what we do and don’t know:
