Eggs: All Things In Moderation?
We asked you for your (health-related) opinion on eggs. We specified that, for the sake of simplicity, let’s say that they are from happy healthy backyard hens who enjoy a good diet.
Apparently this one wasn’t as controversial as it might have been! We (for myth-busting purposes) try to pick something polarizing and sometimes even contentious for our Friday editions, and pick apart what science lies underneath public perceptions.
However, more than half (in fact, 60%) of the subscribers who voted in the poll voted for “Eggs are nutritionally beneficial as part of a balanced diet”, which very moderate statement is indeed pretty much the global scientific consensus.
Still, we’ve a main feature to write, so let’s look at the science, and what the other 40% had in mind:
Eggs are ruinous to health, especially cardiometabolic health: True or False?
False, per best current science, anyway!
Scientific consensus has changed over the years. We learned about cholesterol, then we learned about different types of cholesterol, and now we’ve even learned about in some instances even elevated levels of “bad” cholesterol aren’t necessarily a cause of cardiometabolic disorders so much as a symptom—especially in women.
Not to derail this main feature about eggs (rather than just cholesterol), but for those who missed it, this is actually really interesting: basically, research (pertaining to the use of statins) has found that in women, higher LDL levels aren’t anywhere near the same kind of risk factor as they are for men, and thus may mean that statins (whose main job is reducing LDL) may be much less helpful for women than for men, and more likely to cause unwanted serious side effects in women.
Check out our previous main feature about this: Statins: His & Hers?
But, for back on topic, several large studies (totalling 177,000 people in long-term studies in 50 countries) found:
❝Results from the three cohorts and from the updated meta-analysis show that moderate egg consumption (up to one egg per day) is not associated with cardiovascular disease risk overall, and is associated with potentially lower cardiovascular disease risk in Asian populations.❞
Egg whites are healthy (protein); egg yolks are not (cholesterol): True or False?
True and False, respectively. That is to say, egg whites are healthy (protein), and egg yolks are also healthy (many nutrients).
We talked a bit already about cholesterol, so we’ll not rehash that here. As to the rest:
Eggs are one of the most nutritionally dense foods around. After all, they have everything required to allow a cluster of cells to become a whole baby chick. That’s a lot of body-building!
They’re even more nutritionally heavy-hitters if you get omega-3 enriched eggs, which means the hens were fed extra omega-3, usually in the form of flax seeds.
Also, free-range is better healthwise than others. Do bear in mind that unless they really are from your backyard, or a neighbor’s, chances are that the reality is not what the advertising depicts, though. There are industry minimum standards to be able to advertise as “free-range”, and those standards are a) quite low b) often ignored, because an occasional fine is cheaper than maintaining good conditions.
So if you can look after your own hens, or get them from somewhere that you can see for yourself how they are looked after, so much the better!
Check out the differences side-by-side, though:
Pastured vs Omega-3 vs “Conventional” Eggs: What’s the Difference?
Stallone-style 12-egg smoothies are healthy: True or False?
False, at least if taken with any regularity. One can indeed have too much of a good thing.
So, what’s the “right amount” to eat?
It may vary depending on individual factors (including age and ethnicity), but a good average, according to science, is to keep it to 3 eggs or fewer per day. There are a lot of studies, but we only have so much room here, so we’ll pick one. Its findings are representative of (and in keeping with) the many other studies we looked at, so this seems uncontroversial scientifically:
❝Intake of 1 egg/d was sufficient to increase HDL function and large-LDL particle concentration; however, intake of 2-3 eggs/d supported greater improvements in HDL function as well as increased plasma carotenoids. Overall, intake of ≤3 eggs/d favored a less atherogenic LDL particle profile, improved HDL function, and increased plasma antioxidants in young, healthy adults.❞

Escape Self-Sabotage

Stop Making The Same Mistakes
It’s easy to think that a self-destructive cycle is easy to avoid if you have no special will to self-destruction. However, the cycle is sneaky.
It’s sneaky because it can be passive, and/or omissions rather than actions, procrastinations rather than obvious acts of impulse, and so forth.
So, they’re often things that specifically aren’t there to see.
How to catch them
How often do you think “I wish I had [done xyz]” or “I wish I had [done yxz] sooner”?
Now, how often have you thought that about the same thing more than once? For example, “I should have kept up my exercise”.
For things like this, habit-trackers are a great way to, well, keep track of habits. If for example you planned to do a 10-minute exercise session daily but you’ve been postponing it since you got distracted on January the 2nd, then it’ll highlight that. See also:
How To Really Pick Up (And Keep!) Those Habits
Speaking of habits, this goes for other forms of procrastination, too. For example, if you are always slow to get medical check-ups, or renew your prescriptions, or get ready for some regularly-occurring thing in your schedule, then set a reminder in your preferred way (phone app, calendar on the wall, whatever) and when the appointed time arrives (to book the check-up, renew the prescription, do your taxes, whatever), do it on the day you set your reminder for, as a personal rule for you that you keep to, barring extreme calamity.
By “extreme calamity” we mean less “running late today” and more “house burned down”.
Digital traps
Bad habits can be insidious in other ways too, like getting sucked into social media scrolling (it is literally designed to do that to you; you are not immune modern programming hijacking evolutionary dopamine responses).
Setting a screentime limit (you can specify “just these apps” if you like) will help with this. On most devices, this feature includes a sticky notification in the notification bar, that’ll remind you “27 out of 30 minutes remaining” or whatever you set it for. That’ll remind you to do what you went there to do, instead of getting caught in the endless scroll (and if you went there to just browse, to do so briefly).
Here’s how to set that:
Instructions for iOS devices | Instructions for Android devices
Oh, and on the topic of social media? If you find yourself getting caught up in unproductive arguments on the Internet, try the three-response rule:
- You reply; they reply (no progress made)
- You reply; they reply (still no progress made)
- You reply; they reply (still yet no progress made)
You reply just one more time: “I have a personal rule that if I’m arguing on the Internet and no progress has been made after three replies, I don’t reply further—I find this is helpful to avoid a lot of time lost to pointless arguing that isn’t going anywhere. Best wishes.”
(and then stick to it, no matter how they try to provoke you; best is to just not look until at least the next day)
When “swept up in love” gets to one of those little whirlpools…
The same works in personal relationships, by the way. If for example you are arguing with a loved one and not making progress, it can be good if you both have a pre-arranged agreement that either of you can, up to once on any given day, invoke a “time-out” (e.g. 30 minutes, but you agree the time between you when you first make this standing policy) during which you will both keep out of the other’s way, and come back with a more productive head on (remembering that things go best when it’s you both vs the problem, rather than vs each other).

Seriously Useful Communication Skills: Conflict Resolution
What if the self-sabotaging cycle is active and apparent?
Well, that is less sneaky, but certainly no less serious, and sometimes moreso. An obvious example is drinking too much; this is often cyclical in nature. We wrote about this one previously:
That article’s alcohol-specific, but the same advices go for other harmful activities, including other substance abuse (which in turn includes binge-eating), as well psychological addictions (such as gambling, for example).
Finally…
If your destructive cycle is more of a rut you’ve got stuck in, a common advice is to change something, anything, to get out of the rut.
That can be very bad advice! Because sometimes the change you go for is absolutely not the change that was needed, and is rather just cracking under pressure and doing something impulsive.
Here’s one way to actively get out of a slump:
Behavioral Activation Against Depression & Anxiety
Note: you do not have to be depressed or anxious to do this. But the point is, it’s a tool you can use even if you are depressed and/or anxious, so it’s a good thing to try for getting out of most kinds of slumps.
And really finally, here’s a resource for, well, the title speaks for itself:

The Brain Alarm Signs That Warn Of Dementia

When it comes to predicting age-related cognitive impairment:
First there are genetic factors to take into account (such as the APOE4 gene for Alzheimer’s), as well as things such as age and sex.
When it comes to sex, by the way, what matters here is hormones, which is why [it seems; this as technically as yet unproven with full rigor, but the hypothesis is sound and there is a body of evidence gradually being accumulated to support it] postmenopausal women with untreated menopause get Alzheimer’s at a higher rate and deteriorate more quickly:
Alzheimer’s Sex Differences May Not Be What They Appear
Next, there are obviously modifiable lifestyle factors to take into account, things that will reduce your risk such as getting good sleep, good diet, good exercise, and abstaining from alcohol and smoking, as well as oft-forgotten things such as keeping cognitively active and, equally importantly, socially active:
How To Reduce Your Alzheimer’s Risk
(the article outlines what matters the most in each of the above areas, by the way, so that you can get the most bang-for-buck in terms of lifestyle adjustments)
Lastly (in the category of risk factors), there are things to watch out for in the blood such as hypertension and high cholesterol.
Nipping it in the blood
In new research (so new it is still ongoing, but being at year 2 of a 4-year prospective study, they have published a paper with their results so far), researchers have:
- started with the premise “dementia is preceded by mild cognitive impairment”
- then, asked the question “what are the biometric signs of mild cognitive impairment?”
Using such tools as functional near-infrared spectroscopy (fNIRS) while the participants performed cognitive tasks, they were able to record changes in plasma levels of extracellular vesicles, assessing them with small-particle flow cytometry.
Translating from sciencese: they gave the participants mental tasks, and while they completed them, the researchers scanned their brains and monitored blood flow and the brain’s ability to compensate for any lack of it.
What they found:
- in young adults, blood flow increased, facilitating neurovascular coupling (this is good)
- in older adults, blood flow did not increase as much, but they engaged other areas of the brain to compensate, by what’s called functional connectivity (this is next best)
- in those with mild cognitive impairment, blood flow was reduced, and they did not have the ability to compensate by functional connectivity (this is not good)
They also performed a liquid biopsy, which sounds alarming but it just means they took some blood, and tested this for density of cerebrovascular endothelial extracellular vesicles (CEEVs), which—in more prosaic words—are bits from the cells lining the blood vessels in the brain.
People with mild cognitive impairment had more of these brain bits in their blood than those without.
You can read the paper itself here:
What this means
The science here is obviously still young (being as it is still in progress), but this will likely contribute greatly to early warning signs of dementia, by catching mild cognitive impairment in its early stages, by means of a simple blood test, instead of years of wondering before getting a dementia diagnosis.
And of course, forewarned is forearmed, so if this is something that could be done as a matter of routine upon hitting the age of, say, 65 and then periodically thereafter, it would catch a lot of cases while there’s still more time to turn things around.
As for how to turn things around, well, we imagine you have now read our “How To Reduce Your Alzheimer’s Risk” article linked up top (if not, we recommend checking it out), and there is also…

Health Simplified – by Daniel Cottmeyer
A lot of books focus on the most marketable aspects of health, such as fat loss or muscle gain. Instead, Cottmeyer takes a “birds-eye-view” of health in all its aspects, and then boils it down to the most critical key parts.
Rather than giving a science-dense tome that nobody reads, or a light motivational piece that everyone reads but it amounts to “you can do it!”, here we get substance… but in a digestible form.
Which we at 10almonds love.
The book presents a simple action plan to:
- Improve your relationship with food/exercise
- Actually get better sleep
- Understand how nutrition really works
- Set up helpful habits that are workable and sustainable
- Bring these components together synergistically
Bottom line: if you’re going to buy only one health/fitness book, this is a fine contender.

Fast. Feast. Repeat – by Dr. Gin Stephens
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’ve reviewed intermittent fasting books before, so what makes this one different?
The title “Fast. Feast. Repeat.” doesn’t give much away; after all, we already know that that’s what intermittent fasting is.
After taking the reader though the basics of how intermittent fasting works and what it does for the body, much of the rest of the book is given over to improvements.
That’s what the real strength of this book is: ways to make intermittent fasting more efficient, including how to avoid plateaus. After all, sometimes it can seem like the only way to push further with intermittent fasting is to restrict the eating window further. Not so!
Instead, Dr. Stephens gives us ways to keep confusing our metabolism (in a good way) if, for example, we had a weight loss goal we haven’t met yet.
Best of all, this comes without actually having to eat less.
Bottom line: if you want to be in good physical health, and/but also believe that life is for living and you enjoy eating food, then this book can resolve that age-old dilemma!

Evidence doesn’t support spinal cord stimulators for chronic back pain – and they could cause harm
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.
In an episode of ABC’s Four Corners this week, the use of spinal cord stimulators for chronic back pain was brought into question.
Spinal cord stimulators are devices implanted surgically which deliver electric impulses directly to the spinal cord. They’ve been used to treat people with chronic pain since the 1960s.
Their design has changed significantly over time. Early models required an external generator and invasive surgery to implant them. Current devices are fully implantable, rechargeable and can deliver a variety of electrical signals.
However, despite their long history, rigorous experimental research to test the effectiveness of spinal cord stimulators has only been conducted this century. The findings don’t support their use for treating chronic pain. In fact, data points to a significant risk of harm.
What does the evidence say?
One of the first studies used to support the effectiveness of spinal cord stimulators was published in 2005. This study looked at patients who didn’t get relief from initial spinal surgery and compared implantation of a spinal cord stimulator to a repeat of the spinal surgery.
Although it found spinal cord stimulation was the more effective intervention for chronic back pain, the fact this study compared the device to something that had already failed once is an obvious limitation.
Later studies provided more useful evidence. They compared spinal cord stimulation to non-surgical treatments or placebo devices (for example, deactivated spinal cord stimulators).
A 2023 Cochrane review of the published comparative studies found nearly all studies were restricted to short-term outcomes (weeks). And while some studies appeared to show better pain relief with active spinal cord stimulation, the benefits were small, and the evidence was uncertain.
Only one high-quality study compared spinal cord stimulation to placebo up to six months, and it showed no benefit. The review concluded the data doesn’t support the use of spinal cord stimulation for people with back pain.
What about the harms?
The experimental studies often had small numbers of participants, making any estimate of the harms of spinal cord stimulation difficult. So we need to look to other sources.
A review of adverse events reported to Australia’s Therapeutic Goods Administration found the harms can be serious. Of the 520 events reported between 2012 and 2019, 79% were considered “severe” and 13% were “life threatening”.
We don’t know exactly how many spinal cord stimulators were implanted during this period, however this surgery is done reasonably widely in Australia, particularly in the private and workers compensation sectors. In 2023, health insurance data showed more than 1,300 spinal cord stimulator procedures were carried out around the country.
In the review, around half the reported harms were due to a malfunction of the device itself (for example, fracture of the electrical lead, or the lead moved to the wrong spot in the body). The other half involved declines in people’s health such as unexplained increased pain, infection, and tears in the lining around the spinal cord.
More than 80% of the harms required at least one surgery to correct the problem. The same study reported four out of every ten spinal cord stimulators implanted were being removed.
Chronic back pain can be debilitating. CGN089/Shutterstock High costs
The cost here is considerable, with the devices alone costing tens of thousands of dollars. Adding associated hospital and medical costs, the total cost for a single procedure averages more than $A50,000. With many patients undergoing multiple repeat procedures, it’s not unusual for costs to be measured in hundreds of thousands of dollars.
Rebates from Medicare, private health funds and other insurance schemes may go towards this total, along with out-of-pocket contributions.
Insurers are uncertain of the effectiveness of spinal cord stimulators, but because their implantation is listed on the Medicare Benefits Schedule and the devices are approved for reimbursement by the government, insurers are forced to fund their use.
Industry influence
If the evidence suggests no sustained benefit over placebo, the harms are significant and the cost is high, why are spinal cord stimulators being used so commonly in Australia? In New Zealand, for example, the devices are rarely used.
Doctors who implant spinal cord stimulators in Australia are well remunerated and funding arrangements are different in New Zealand. But the main reason behind the lack of use in New Zealand is because pain specialists there are not convinced of their effectiveness.
In Australia and elsewhere, the use of spinal cord stimulators is heavily promoted by the pain specialists who implant them, and the device manufacturers, often in unison. The tactics used by the spinal cord stimulator device industry to protect profits have been compared to tactics used by the tobacco industry.
A 2023 paper describes these tactics which include flooding the scientific literature with industry-funded research, undermining unfavourable independent research, and attacking the credibility of those who raise concerns about the devices.
It’s not all bad news
Many who suffer from chronic pain may feel disillusioned after watching the Four Corners report. But it’s not all bad news. Australia happens to be home to some of the world’s top back pain researchers who are working on safe, effective therapies.
New approaches such as sensorimotor retraining, which includes reassurance and encouragement to increase patients’ activity levels, cognitive functional therapy, which targets unhelpful pain-related thinking and behaviour, and old approaches such as exercise, have recently shown benefits in robust clinical research.
If we were to remove funding for expensive, harmful and ineffective treatments, more funding could be directed towards effective ones.

Peace Is Every Step – by Thích Nhất Hạnh
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.
Mindfulness is one of the few practices to make its way from religion (in this case, Buddhism) into hard science. We’ve written before about its many evidence-based benefits, and many national health information outlets recommend it. So, what does this book have to add?
Thích Nhất Hạnh spent most of his 95 years devoted to the practice and teaching of mindfulness and compassion. In this book, the focus is on bringing mindfulness off the meditation mat and into general life.
After all, what if we could extend that “unflappability” into situations that pressure and antagonize us? That would be some superpower!
The author offers techniques to do just that, simple exercises to transform negative emotions, and to make us more likely to remember to do so.
After all, “in the heat of the moment” is rarely when many of us are at our best, this book gives way to allow those moments themselves to serve as immediate triggers to be our best.
The title “Peace Is Every Step” is not a random collection of words; the goal of this book is to enable to reader to indeed carry peace with us as we go.
Not just “peace is always available to us”, but if we do it right: “we have now arranged for our own peace to automatically step in and help us when we need it most”.
Bottom line: if you’d like to practice mindfulness, or practice it more consistently, this book offers some powerful tools.
