Regular Nail Polish vs Gel Nail Polish – Which is Healthier?

Our Verdict
When comparing regular nail polish to gel nail polish, we picked the regular.
Why?
This one’s less about what’s in the bottle, and more about what gets done to your hands:
- Regular nail polish application involves carefully brushing it on.
- Regular nail polish removal involves wiping with acetone.
…whereas:
- Gel nail polish application involves deliberately damaging (roughing up) the nail to allow the color coat to adhere, then when the top coat is applied, holding the nails (and thus, the attached fingers) under a UV light to set it. That UV lamp exposure is very bad for the skin.
- Gel nail polish removal involves soaking in acetone, which is definitely worse than wiping with acetone. Failure to adequately soak it will result in further damage to the nail while trying to get the base coat off the nail that you already deliberately damaged when first applying it.
All in all, regular nail polish isn’t amazing for nail health (healthiest is for nails to be free and naked), but for those of us who like a little bit of color there, regular is a lot better than gel.
Gel nail polish damages the nail itself by necessity, and presents a cumulative skin cancer risk and accelerated aging of the skin, by way of the UV lamp use.
For your interest, here are the specific products that we compared, but the above goes for any of this kind:

Food for Life – by Dr. Tim Spector
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.
This book is, as the author puts it, “an eater’s guide to food and nutrition”. Rather than telling us what to eat or not eat, he provides an overview of what the latest science has to say about various foods, and leaves us to make our own informed decisions.
He also stands firmly by the “personalized nutrition” idea that he introduced in his previous book which we reviewed the other day, and gives advice on what tests we might like to perform.
The writing style is accessible, without shying away from reference to hard science. Dr. Spector provides lots of information about key chemicals, genes, gut bacteria, and more—as well as simply providing a very enjoyable read along the way.
Bottom line: if you’d like a much better idea of what food is (and isn’t) doing what, this book is an invaluable resource.

Caramelized Caraway Cabbage
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.
Cabbage is an underrated vegetable for its many nutrients and its culinary potential—here’s a great way to make it a delectable starter or respectable side.
You will need
- 1 medium white cabbage, sliced into 1″ thick slabs
- 1 tbsp extra-virgin olive oil
- 1 tbsp caraway seeds
- 1 tsp black pepper
- ½ tsp turmeric
- ¼ tsp MSG or ½ tsp low-sodium salt
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 400℉ / 200℃.
2) Combine the non-cabbage ingredients in a small bowl, whisking to mix thoroughly—with a tiny whisk if you have one, but a fork will work if necessary.
3) Arrange the cabbage slices on a lined baking tray and brush the seasoning-and-oil mixture over both sides of each slice.
4) Roast for 20–25 minutes until the cabbage is tender and beginning to caramelize.
5) Serve warm.
Enjoy!

Most People Try The Wrong Way To Unshrimp Their Posture (Here’s How To Do It Better)
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.
Many people try to correct posture by pulling the shoulders back and tucking in the chin, but that doesn’t work. Happily, there is a way that does! Kinesiologist Kyle Waugh demonstrates:
Defying gravity
The trick is simple, and is about how maintaining good posture needs to be unconscious and natural, not forced. After all, who is maintaining singular focus for 16 waking hours a day?
Instead, pay attention to how the body relates to gravity without excessive muscle tension, aligning the (oft-forgotten!) hips, and maintaining balance. The importance of hip position is really not to be underestimated, since in many ways the hips are a central axis of the body just as the spine is, and the spine itself sits in the hips.
A lot of what holds the body in poor posture tends to be localized muscle tensions, so address those with stretches and relaxation exercises.

The Lifestyle Factors That Matter >8 Times More Than Genes
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 said before that “genes predispose; they don’t predetermine”. It can be good to know one’s genes, of course, and we’ve written about this here:
Genetic Testing: Health Benefits & Methods
…which can include some quite contemporary risks, such as:
Genetic Risk Factors For Long COVID
And yet…
Nurture Over Nature
A very large (n=492,567) study looked into the impact of 25 lifestyle/environmental factors, of which 23 are considered modifiable, and found that lifestyle/environmental factors accounted for 17% of the variation in mortality risk, while genetic predisposition accounted for less than 2%.
Which is good news, because it means we can improve our lot.
But how?
The strongest negative factors (that increased mortality the most) were:
- Smoking
- Not owning your home (interestingly, “live in accommodation rent-free vs own” performed just as badly as various kinds of “renting home vs own”, while “own house with mortgage, vs own outright” had only a marginal negative effect)
- Sleeping more than 9 hours per day (performed even worse than sleeping under 7 hours per day, which also increased mortality risk, but not by as much as oversleeping)
- Financial difficulties in the past two years
- Homosexuality
- Unemployment
- Being an evening person
- Lonely lifestyle
- Frequent napping
We may hypothesize that homosexuality probably makes the list because of how it makes one more likely to have other items on the list, especially unemployment, and the various poverty-related indicators that come from unemployment.
Being an evening person, whatever its pathology, is a well-established risk factor that we’ve talked about before:
Early Bird Or Night Owl? Genes vs Environment ← this is also, by the way, an excellent example of how “genes predispose; they don’t predetermine”, because there is a genetic factor involved, and/but we absolutely can switch it up, if we go about it correctly, and become a morning person without trying to force it.
The strongest positive factors (that decreased mortality the most) were:
- The inverse of all of the various above things, e.g. never having smoked, owning your own home, etc
- Household income, specifically
- Living with a partner
- Having oil central heating
- Gym use
- Sun protection use
- Physical activity, especially if in leisure time rather than as part of one’s work
- Glucosamine supplements
- Family visit frequency
- Cereal fiber intake (i.e. whole grains)
We may hypothesize that having oil central heating is simply a more expensive option to install than many, and therefore likely one enjoyed by homeowners more often than renters.
We may hypothesize that glucosamine supplementation is an indication of the type of person who takes care of a specific condition (inflammation of the joints) without an existential threat; notably, multivitamin supplements don’t get the same benefit, probably because of their ubiquity.
We may hypothesize that “family visit frequency” is highly correlated to having a support network, being social (and thus not lonely), and likely is associated with household income too.
You can see the full list of factors and their impacts, here:
Environmental architecture of mortality in the UKB ← that’s the UK Biobank
You can read the paper in full, here:
Integrating the environmental and genetic architectures of aging and mortality
Practical takeaways
The priorities seem to be as follows:
Don’t smoke. Ideally you will never have smoked, but short of a time machine, you can’t change that now, so: what you can do is quit now if you haven’t already.
See also: Which Addiction-Quitting Methods Work Best?
Note that other factors often lumped in with such, for example daily alcohol consumption, red meat intake, processed meat intake, and salt intake, all significantly increased mortality risk, but none of them in the same league of badness as smoking.
See also: Is Sugar The New Smoking? ← simply put: no, it is not. Don’t get us wrong; added sugar is woeful for the health, but smoking is pretty much the worst thing you can do for your health, short of intentionally (and successfully) committing suicide.
Be financially secure, ideally owning your own home. For many (indeed, for most people in the world) this may be an “easier said than done” thing, but if you can make decisions that will improve your financial security, the mortality numbers are very clear on this matter.
Be social, as loneliness indeed kills, in numerous ways. Loneliness means a lack of a support network, and it means a lack of social contact (thus increased risk of cognitive decline), and likely decreased ikigai, unless your life’s purpose is something inherently linked to solitude (e.g. the “meditating on top of a mountain” archetype).

And to fix it: How To Beat Loneliness & Isolation
Be active: especially in your leisure time; being active because you have to does convey benefits, but on the same level as physical activity because you want to.
See also: No-Exercise Exercises (That Won’t Feel Like “Having To Do” Exercise)
Use sunscreen: we’re surprised this one made the list; it’s important to avoid skin cancer of course, but we didn’t think it’d be quite such a driver of mortality risk mitigation as the numbers show it is, and we can’t think of a clear alternative explanation, as we could with some of the other “why did this make the list?” items. At worst, it could be a similar case to that of glucosamine use, and thus is a marker of a conscientious person making a regular sustained effort for their health. Either way, it seems like a good idea based on the numbers.

How To Rebuild Your Neurons’ Myelin Sheaths
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.
PS: We Love You
Phosphatidylserine, or “PS” for short, is a phospholipid found in the brain. In other words, a kind of fatty compound that is such stuff as our brains are made of.
In particular, it’s required for healthy nerve cell membranes and myelin (the protective sheath that neurons live in—basically, myelin sheaths do for neurons what telomere caps do for DNA).
For an overview that’s more comprehensive than we have room for here, check out:
Phosphatidylserine and the human brain
Many people take it as a supplement.
Does taking it as a supplement work?
This is a valid question, as a lot of supplements can’t be absorbed well, and/or can’t pass the blood-brain barrier. But, as the above-linked study notes:
❝Exogenous PS (300-800 mg/d) is absorbed efficiently in humans, crosses the blood-brain barrier, and safely slows, halts, or reverses biochemical alterations and structural deterioration in nerve cells. It supports human cognitive functions, including the formation of short-term memory, the consolidation of long-term memory, the ability to create new memories, the ability to retrieve memories, the ability to learn and recall information, the ability to focus attention and concentrate, the ability to reason and solve problems, language skills, and the ability to communicate. It also supports locomotor functions, especially rapid reactions and reflexes.❞
(“Exogenous” means “coming from outside of the body”, as opposed to “endogenous”, meaning “made inside the body”. Effectively, in this context “exogenous” means “taken as a supplement”.)
Why do people take it?
The health claims for phosphatidylserine fall into two main categories:
- Neuroprotection (helping your brain to avoid age-related decline in the long term)
- Cognitive enhancement (helping your brain work better in the short term)
What does the science say?
There’s a lot of science that’s been done on the neuroprotective properties of PS, and there are thousands of studies we could draw from here. The upshot is that regular phosphatidylserine supplementation (most often 300mg/day, but studies are also found for 100–500mg/day) is strongly associated with a reduction in cognitive decline over the course of 12 weeks (a common study duration). Here are a some spotlight studies showing this:
- Effects of phosphatidylserine in Alzheimer’s disease
- Double-blind cross-over study of phosphatidylserine vs. placebo in patients with early dementia of the Alzheimer type
- Effect of Phosphatidylserine on Cerebral Glucose Metabolism in Alzheimer’s Disease
- The effect of soybean-derived phosphatidylserine on cognitive performance in elderly with subjective memory complaints
Note: PS can be derived from various sources, with the two most common forms being bovine (i.e., from cow brains) or soy-derived.
There is no established difference in the efficacy of these.
There have been some concerns raised about the risk of CJD (the human form of BSE, as in “mad cow disease”) from consuming brain matter from cows, but studies have not found any evidence of this actually happening.
There is also some evidence that phosphatidyserine significantly boosts cognitive performance, even in young people with no extant cognitive decline, for example:
(as the title suggests, they did also test for its effect on mood and endocrine response, but found it made no difference to those, just the cognitive function—which enjoyed a boost before exercise, as well as after it, meaning that the boost wasn’t dependent on the exercise)
PS for cognitive enhancement in the young and healthy is not nearly so well-explored as its use as a later-life guard against age-related cognitive decline. However, just because the studies in younger people are dwarfed in number by the studies in older people, doesn’t detract from the validity of the studies in younger people.
Basically: its use in older people has been studied the most, but all available evidence points to it being beneficial to brain health at all ages.

We don’t sell it (or anything else), but for your convenience, here’s an example product on Amazon.

Can We Side-Step Age-Related Alienation?
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.
When The World Moves Without Us…
We’ve written before about how reduced social engagement can strike people of all ages, and what can be done about it:
How To Beat Loneliness & Isolation
…but today we’re going to talk more about a specific aspect of it, namely, the alienation that can come with old age—and other life transitions too, but getting older is something that (unless accident or incident befall us first) all of us will definitely do.
What’s the difference?
Loneliness is a status, alienation is more of a process. It can be the alienation in the sense of an implicit “you don’t belong here” message from the world that’s geared around the average person and thus alienates those who are not that (a lack of accessibility to people with disabilities can be an important and very active example of this), and it can also be an alienation from what we’ve previously considered our “niche” in the world—the loss of purpose many people feel upon retirement fits this bill. It can even be a more generalized alienation from our younger selves; it’s easy to have a self-image that doesn’t match one’s current reality, for instance.
Read more: Estranged by Time: Alienation in the Aging Process
So, how to “un-alienate”?
To “un-alienate”, that is to say, to integrate/reintegrate, can be hard. Some things may even be outright impossible, but most will not be!
Consider how, for example, former athletes become coaches—or for that matter, how former party-goers might become party-hosts (even if the kind of “party” might change with time, give or take the pace at which we like to live our lives).
What’s important is that we take what matters the most to us, and examine how we can realistically still engage with that thing.
This is different from trying to hold on grimly to something that’s no longer our speed.
Letting go of the only thing we’ve known will always be scary; sometimes it’s for the best, and sometimes what we really need is just more of a pivot, like the examples above. The crux lies in knowing which:
- Is our relationship with the thing (whatever it may be) still working for us, or is it just bringing strife now?
- If it’s not working for us, is it because of a specific aspect that could be side-stepped while keeping the rest?
- If we’re going to drop that thing entirely (or be dropped by it, which, while cruel, also happens in life), then where are we going to land?
This latter is one where foresight is a gift, because if we bury our heads in the sand we’re going to land wherever we’re dropped, whereas if we acknowledge the process, we can make a strategic move and land on our feet.
Here’s a good pop-science article about this—it’s aimed at people around retirement age, but honestly the advice is relevant for people of all ages, and facing all manner of life transitions, e.g. career transitions (of which retirement is of course the career transition to end all career transitions), relationship transitions (including B/B/B/B: births, betrothals/break-ups, and bereavements) health transitions (usually: life-changing illnesses and/or disabilities—which again, happens to most of us if something doesn’t get us first), etc. So with all that in mind, this becomes more of a “how to reassess your life at those times when it needs reassessing”:
How to Reassess Your Life in Retirement
But that doesn’t mean that letting go is always necessary
Sometimes, the opposite! Sometimes, the age-old advice to “lean in” really is all the situation calls for, which means:
- Be ready to say “yes” to things, and if nobody’s asking, be ready to “hey, do you wanna…?” and take a “build it and they will come” approach. This includes with people of different ages, too! Intergenerational friendships can be very rewarding for all concerned, if done right. Communities that span age-ranges can be great for this—they might be about special interests (this writer has friends ranging through four generations from playing chess, for instance), they could be religious communities if we be religious, LGBT groups if that fits for us, even mutual support groups such as for specific disabilities or chronic illness if we have such—notice how the very things that might isolate us can also bring us together!
- Be open-minded to new experiences; it’s easy to get stuck in a rut of “I’ve never done that” and mistake that self-assessment for an uncritical assumption of “I’m not the kind of person who does that”. Sometimes, you really won’t be! But at least think about it and entertain the possibility, before dismissing it out of hand. And, here’s a life tip: it can be really good to (within the realms of safety, and one’s personal moral principles, of course) take an approach of “try anything once”. Even if we’re almost certain we won’t like it, and even if we then turn out to indeed not like it, it can be a refreshing experience—and now we can say “Yep, tried that, not doing that again” from a position of informed knowledge. That’s the only way we get to look back on a richly lived life of broad experiences, after all, and it is never too late for such.
- Be comfortable prioritizing quality over quantity. This goes for friends, it goes for activities, it goes for experiences. The topic of “what’s the best number of friends to have?” has been a matter of discussion since at least ancient Greek times (Plato and Aristotle examined this extensively), but whatever number we might arrive at, it’s clear that quality is the critical factor, and quantity after that is just a matter of optimizing.
In short: make sure you’re investing—in your relationships, in your areas of interest, in your community (whatever that may mean for you personally), and most of all, and never forget this: in yourself.
Take care!
