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.❞
Enjoy!

Which Vitamin Brands Are Effective?
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.
It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝As far as specific brands of vitamin…some are good some not. I don’t like being told what buy but I guess I want to know which are effective. Could there be some brands recognized as good given to us?❞
The most reliable brands are generally those with the most transparency:
- They tell you what is in the supplement; not just the active ingredient(s), with doses, but also any buffers etc.
- They tell you, in the case of ingredients that can have various different sources, what the source is.
- They are, ideally, well-certified and independently tested.
Our previous sponsor Ora is a good example of a company that does this.
Additionally, in terms of bioavailability, generally speaking the order of preference goes liquid > capsule/softgel > tablet, so that’s something to look out for, too.
Note: “liquid” includes powders that are ingested when dissolved/suspended in water, and also includes tablets that become a liquid when dissolved/dispersed in water and ingested that way.

Scarcity Brain – by Michael Easter
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.
After a brief overview of theevolutionary psychology underpinnings of the scarcity brain, the author grounds the rest of this book firmly in the present. He explains how the scarcity loop hooks us and why we crave more, and what factors can increase or lessen its hold over us.
As for what things we are wired to consider “potentially scarce any time now” no matter how saturated we are in them, he looks at an array of categories, each with their nuances. From the obvious such as “food” and “stuff“, to understandable “information” and “happiness“, to abstractions like “influence“, he goes to many sources—experts of various kinds from around the world—to explore how we can know “how much is enough”, and—which can be harder—act accordingly.
The key, he argues, is not in simply wanting less, but in understanding why we crave more in the first place, get rid of our worst habits, and use what we already have, better.
Bottom line: if you feel a gnawing sense of needing more “to be on the safe side”, this book can help you to be a little more strategic (and at the same time, less stressed!) about that.

Sleep wrinkles are real. Here’s how they leave their mark
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.
You wake up, stagger to the bathroom and gaze into the mirror. No, you’re not imagining it. You’ve developed face wrinkles overnight. They’re sleep wrinkles.
Sleep wrinkles are temporary. But as your skin loses its elasticity as you age, they can set in.
Here’s what you can do to minimise the chance of them forming in the first place.
How side-sleeping affects your face
Your skin wrinkles for a number of reasons, including ageing, sun damage, smoking, poor hydration, habitual facial expressions (such as grinning, pouting, frowning, squinting) and sleeping positions.
When you sleep on your side or stomach, your face skin is squeezed and crushed a lot more than if you sleep on your back. When you sleep on your side or stomach, gravity presses your face against the pillow. Your face skin is distorted as your skin is stretched, compressed and pulled in all directions as you move about in your sleep.
You can reduce these external forces acting on the face by sleeping on your back or changing positions frequently.
Doctors can tell which side you sleep on by looking at your face
In a young face, sleep wrinkles are transient and disappear after waking.
Temporary sleep wrinkles can become persistent with time and repetition. As we age, our skin loses elasticity (recoil) and extensibility (stretch), creating ideal conditions for sleep wrinkles or lines to set in and last longer.
The time spent in each sleeping position, the magnitude of external forces applied to each area of the face, as well as the surface area of contact with the pillow surface, also affects the pattern and rate of sleep wrinkle formation.
Skin specialists can often recognise this. People who favour sleeping on one side of their body tend to have a flatter face on their sleeping side and more visible sleep lines.
Can a night skincare routine avoid sleep wrinkles?
Collagen and elastin are two primary components of the dermis (inner layer) of skin. They form the skin structure and maintain the elasticity of skin.
The dermis is the inner layer of skin. mermaid3/Shutterstock Supplementing collagen through skincare routines to enhance skin elasticity can help reduce wrinkle formation.
Hyaluronic acid is a naturally occurring molecule in human bodies. It holds our skin’s collagen and elastin in a proper configuration, stimulates the production of collagen and adds hydration, which can help slow down wrinkle formation. Hyaluronic acid is one of the most common active ingredients in skincare creams, gels and lotions.
Moisturisers can hydrate the skin in different ways. “Occlusive” substances produce a thin layer of oil on the skin that prevents water loss due to evaporation. “Humectants” attract and hold water in the skin, and they can differ in their capacity to bind with water, which influences the degree of skin hydration.
Do silk pillowcases actually make a difference?
Can they help? New Africa/Shutterstock Silk pillowcases can make a difference in wrinkle formation, if they let your skin glide and move, rather than adding friction and pressure on a single spot. If you can, use silk sheets and silk pillows.
Studies have also shown pillows designed to reduce mechanical stress during sleep can prevent skin deformations. Such a pillow could be useful in slowing down and preventing the formation of certain facial wrinkles.
Sleeping on your back can reduce the risk of sleep lines, as can a nighttime routine of moisturising before sleep.
Otherwise, lifestyle choices and habits, such quitting smoking, drinking plenty of water, a healthy diet (eating enough vegetables, fruits, nuts, seeds, healthy fats, yogurt and other fermented foods) and regular use of sunscreens can help improve the appearance of the skin on our face.

Metabolical – by Dr. Robert Lustig
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.
The premise of this book itself is not novel: processed food is bad, food giants lie to us, and eating better makes us less prone to disease (especially metabolic disease).
What this book does offer that’s less commonly found is a comprehensive guide, a walkthrough of each relevant what and why and how, with plenty of good science and practical real-world examples.
In terms of unique selling points, perhaps the greatest strength of this book is its focus on two things in particular that affect many aspects of health: looking after our liver, and looking after our gut.
The style is… A little dramatic perhaps, but that’s just the style; there’s no hyperbole, he is stating well-established scientific facts.
Bottom line: very much of chronic disease would be a lot less diseasey if we all ate with these aspects of our health in mind. This book’s a comprehensive guide to that.

One in twenty people has no sense of smell – here’s how they might get it back
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.
During the pandemic, a lost sense of smell was quickly identified as one of the key symptoms of COVID. Nearly four years later, one in five people in the UK is living with a decreased or distorted sense of smell, and one in twenty have anosmia – the total loss of the ability to perceive any odours at all. Smell training is one of the few treatment options for recovering a lost sense of smell – but can we make it more effective?
Smell training is a therapy that is recommended by experts for recovering a lost sense of smell. It is a simple process that involves sniffing a set of different odours – usually essential oils, or herbs and spices – every day.
The olfactory system has a unique ability to regenerate sensory neurons (nerve cells). So, just like physiotherapy where exercise helps to restore movement and function following an injury, repeated exposure to odours helps to recover the sense of smell following an infection, or other cause of smell loss (for example, traumatic head injury).
Several studies have demonstrated the effectiveness of smell training under laboratory conditions. But recent findings have suggested that the real-world results might be disappointing.
One reason for this is that smell training is a long-term therapy. It can take months before patients detect anything, and some people may not get any benefit at all.
In one study, researchers found that after three months of smell training, participation dropped to 88%, and further declined to 56% after six months. The reason given was that these people did not feel as though they noticed any improvement in their ability to smell.
Cross-modal associations
To remedy this, researchers are now investigating how smell training can be improved. One interesting idea is that information from our other senses, or “cross-modal associations”, can be applied to smell training to promote odour perception and improve the results.
Cross-modal associations are described as the tendency for sensory cues from different sensory systems to be matched. For example, brightness tends to be associated with loudness. Pitch is related to size. Colours are linked to temperature, and softness is matched with round shapes, while spiky shapes feel more rough. In previous studies, these associations have been shown to have a considerable influence on how sensory information is processed. Especially when it comes to olfaction.
Recent research has shown that the sense of smell is influenced by a combination of different sensory inputs – not just odours. Sensory cues such as colour, shape, and pitch are believed to play a role in the ability to correctly identify and name odours, and can influence perceptions of odour pleasantness and intensity.
In one study, participants were asked to complete a test that measured their ability to discriminate between different odours while they were presented with the colour red or yellow, an outline drawing of a strawberry or a lemon, or a combination of these colours and shapes. The results suggested that corresponding odour and colour associations (for example, the colour red and strawberry) were linked to increased olfactory performance compared with odours and colours that were not associated (for example, the colour yellow and strawberry).
People who associated strawberries with the colour red performed better on smell tests. GCapture/Shutterstock While projects focusing on harnessing these cross-modal associations to improve treatments for smell loss are underway, research has already started to deliver some promising results.
In a recent study that aimed to investigate whether the effects of smell training could be improved with the addition of cross-modal associations, participants watched a guidance video containing sounds that matched the odours that they were training with. The results suggest that cross-modal interactions plus smell training improved olfactory function compared to smell training alone.
The results reported in recent studies have been promising and offer new insights into the field of olfactory science. It is hoped that this will soon lead to the development of more effective treatment options for smell recovery.
In the meantime, smell training is one of the best things you can do for a lost sense of smell, so patients are encouraged to stick with it so that they give themselves the best chance at recovery.

Pine Nuts vs Macadamia 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 pine nuts to macadamias, we picked the pine nuts.
Why?
In terms of macros, it’s subjective depending on what you want to prioritize; the two nuts are equal in carbs, but pine nuts have more protein and macadamias have more fiber. We’d generally prioritize the fiber, which so far would give macadamias a win in this category, but if you prefer the protein, then consider it pine nuts. Next, we must consider fats; macadamias have slightly more fat, and of which, proportionally more saturated fat, resulting in 3x the total saturated fat compared to pine nuts, gram for gram. With this in mind, we consider this category a tie or a marginal nominal win for pine nuts.
In the category of vitamins, pine nuts have more of vitamins A, B2, B3, B9, E, K, and choline, while macadamias have more of vitamins B1, B5, B6, and C. A clear win for pine nuts this time, especially with pine nuts having more than 17x the vitamin E of macadamias.
When it comes to minerals, pine nuts have more copper, iron, magnesium, manganese, phosphorus, potassium, and zinc, while macadamias have more calcium and selenium. Another easy win for pine nuts.
In short, enjoy either or both (diversity is good), but pine nuts are the healthier by most metrics.
