It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
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 😎
❝Do essential oils really have scientific merit?❞
Great question! Assuming you mean “…for medicinal purposes” then it really depends on the oil in question.
For example, one can probably buy a big book of essential oils from a New Age store, and a lot of claims for different oils will not have any scientific backing whatsoever.
However! Some definitely do. For example, we wrote a little while back about ginger:
Ginger Does A Lot More Than You Think
Now, the active compound that gives ginger those properties and more is gingerol. Which is usually found as pure ginger oil, in other words, ginger essential oil.
Another essential oil that definitely does have benefits is that of Boswellia serrata, commonly known as frankincense. It can be used in various forms, and the essential oil is one of them; see:

- When Painkillers Aren’t Helping, These Things Might: Science-Based Alternative Pain Relief
Meanwhile, menthol, the essential oil of peppermint, has its pros and cons:

And lavender essential oil does really have a sedative effect:

If you have a different, particular essential oil in mind, let us know, and we can do a deep-dive on it for one of our “Research Review” editions!
A note on safety
Essential oils are pure and undiluted extracts of what’s usually a particularly potent chemical from a plant. Two things to bear in mind about this:
- Just because a chemical is potent, does not mean it will necessarily help you in a specific way, or indeed at all. On the contrary, many potent chemicals are simply harmful. So, be careful.
- Essential oils being so strong means that usually only a drop or two is required for effects; consult available literature (or ask us to do that for you!), and employ good safety practices such as:
- Do not use undiluted essential oils on your skin or internally
- If you are going to use it internally (diluted, following instructions from a reputable source, and with your doctor’s blessing, please) then test it on your skin first at the same dilution, in case of any adverse reaction.
- However you are using it, if you have any kind of adverse reaction, stop, and seek medical attention if it’s severe and/or it persists.
Take care!

Resistance Is Useful! (Especially As We Get Older)
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.
Resistance Is Useful!
At 10almonds we talk a lot about the importance of regular moderate exercise (e.g. walking, gardening, housework, etc), and with good reason: getting in those minutes (at least 150 minutes per week, so, a little over 20 minutes per day, or 25 minutes per day with one day off) is the exericise most consistently linked to better general health outcomes and reduced mortality risk.
We also often come back to mobility, because at the end of the day, being able to reach for something from a kitchen cabinet without doing oneself an injury is generally more important in life than being able to leg-press a car.
Today though, we’re going to talk about resistance training.
What is resistance training?
It can be weight-lifting, or it can be bodyweight exercises. In those cases, what you’re resisting is gravity. It can also be exercises with resistance bands or machines. In all cases, it’s about building and/or maintaining strength.
Why does it matter?
Let’s say you’re not an athlete, soldier, or laborer, and the heaviest thing you have to pick up is a bag of groceries. Strength still matters, for two main reasons:
- Muscle strength correlates to bone strength. You can’t build (or maintain) strong muscles on weak bones, so if you take care of your muscles, then your body will keep your bones strong too.
- That’s assuming you have a good diet as well—but today’s not about that. If you’d like to know more about eating for bone health though, do check out this previous article about that!
- Muscle strength correlates to balance and stability. You can’t keep yourself from falling over if you are physically frail.
Both of those things matter, because falls and fractures often have terrible health outcomes (e.g., slower recovery and more complications) the older we get. So, we want to:
- Ideally, not fall in the first place
- If we do fall, have robust bones
See also: Effects of Resistance Exercise on Bone Health
How much should we do?
Let’s go to the Journal of Strength and Conditioning Research on this one:
❝There is strong evidence to support the benefits of resistance exercise for countering many age-related processes of sarcopenia, muscle weakness, mobility loss, chronic disease, disability, and even premature mortality.
In addition, this Position Statement provides specific evidence-based practice recommendations to aid in the implementation of resistance exercise programs for healthy older adults and those with special considerations.
While there are instances where low-intensity, low-volume programs are appropriate (i.e., beginning programs for individuals with frailty or CVDs), the greatest benefits are possible with progression to moderate to higher intensity programs.❞
~ Fragala et al
Read the statement in full:
There’s a lot of science there and it’s well worth reading if you have the time. It’s particularly good at delineating how much is not enough vs how much is too much, and the extent to which we should (or shouldn’t) train to exhaustion.
If you don’t fancy that, though, and/or just want to start with something accessible and work your way up, the below is a very good (and also evidence-based) start-up plan:

Dr. Jaime Seeman: Hard To Kill?
This is Dr. Jaime Seeman. She’s a board-certified obstetrician-gynecologist with a background in nutrition, exercise, and health science. She’s also a Fellow in Integrative Medicine, and a board-certified nutrition specialist.
However, her biggest focus is preventative medicine.
What does she want us to know?
The Five Pillars of being “Hard to Kill”!
As an athlete when she was younger, she got away with poor nutrition habits with good exercise, but pregnancy (thrice) brought her poor thyroid function, other hormonal imbalances, and pre-diabetes.
So, she set about getting better—not something the general medical establishment focuses on a lot! Doctors are pressured to manage symptoms, but are under no expectation to actually help people get better.
So, what are her five pillars?
Nutrition
Dr. Seeman unsurprisingly recommends a whole-foods diet with lots of plants, but unlike many plant-enjoyers, she is also an enjoyer of the ketogenic diet.
While keto-enthusiasts say “carbs are bad” and vegans say “meat is bad”, the reality is: both of those things can be bad, and in both cases, avoiding the most harmful varieties is a very good first step:
Movement
This is in two parts:
- get your 150 minutes of moderate exercise per week
- keep your body mobile!
See also:
Sleep
This one’s quite straightforward, and Dr. Seeman uncontroversially recommends getting 7–9 hours per night; yes, even you:
Mindset
This is key to Dr. Seeman’s approach, and it is about not settling for average, because the average is undernourished, overmedicated, sedentary, and suffering.
She encourages us all to keep working for better health, wherever we’re at. To not “go gentle into that good night”, to get stronger whatever our age, to showcase increasingly robust vitality as we go.
To believe we can, and then to do it.
Environment
That previous item usually won’t last beyond a 10-day health-kick without the correct environment.
As for how to make sure we have that? Check out:

How to Eat 30 Plants a Week – by Hugh Fearnley-Whittingstall
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.
If you’re used to eating the same two fruits and three vegetables in rotation, the “gold standard” evidence-based advice to “eat 30 different plants per week” can seem a little daunting.
Where this book excels is in reminding the reader to use a lot of diverse plants that are readily available in any well-stocked supermarket, but often get forgotten just because “we don’t buy that”, so it becomes invisible on the shelf.
It’s not just a recipe book (though yes, there are plenty of recipes here); it’s also advice about stocking up and maintaining that stock, advice on reframing certain choices to inject a little diversity into every meal without it become onerous, meal-planning rotation advice, and a lot of recipes that are easy but plant-rich, for example “this soup that has these six plants in it”, etc.
He also gives, for those eager to get started, “10 x 3 recipes per week to guarantee your 30”, in other words, 10 sets of 3 recipes, wherein each set of 3 recipes uses >30 different plants between them, such that if we have each of these set-of-three meals over the course of the week, then what we do in the other 4–18 meals (depending on how many meals per day you like to have) is all just a bonus.
The latter is what makes this book an incredibly stress-free approach to more plant-diverse eating for life.
Bottom line: if you want to be able to answer “do you get your five-a-day?” with “you mean breakfast?” because you’ve already hit five by breakfast each day, then this is the book for you.
Click here to check out How To Eat 30 Plants A Week, and indeed eat 30+ different plants per week!

The Alzheimer’s Gene That Varies By Race & Sex
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 Alzheimer’s Gene That Varies By Race & Sex
You probably know that there are important genetic factors that increase or decrease Alzheimer’s Risk. If you’d like a quick refresher before we carry on, here are two previous articles on this topic:
- Genetic Testing: Health Benefits & Methods (about personal genomics and health, including Alzheimer’s)
- The Surprising Link Between Type 2 Diabetes & Alzheimer’s (about the APOE-ε4 allele that is implicated in both)
A Tale of Two Alleles
It has generally been understood that APOE-ε2 lowers Alzheimer’s disease risk, and APOE-ε4 increases it.
However, for reasons beyond the scope of this article, research populations for genetic testing are overwhelmingly white. If you, dear reader, are white, you may be thinking “well, I’m white, so this isn’t a problem for me”, you might still want to read on…
An extensive new study, published days ago, by Dr. Belloy et al., looked at how these correlations held out per race and sex. They found:
- The “APOE-ε2 lowers; APOE-ε4 increases” dictum held out strongest for white people.
- In the case of Hispanic people, there was only a small correlation on the APOE-ε4 side of things, and none on the APOE-ε2 side of things per se.
- East Asians also saw no correlation with regard to APOE-ε2 per se.
- But! Hispanic and East Asian people had a reduced risk of Alzheimer’s if and only if they had both APOE-ε2 and APOE-ε4.
- Black people, meanwhile, saw a slight correlation with regard to the protective effect of APOE-ε2, and as for APOE-ε4, if they had any European ancestry, increased European ancestry meant a higher increased risk factor if they had APOE-ε4. African ancestry, on the other hand, had a protective effect, proportional to the overall amount of that ancestry.
And as for sex…
- Specifically for white people with the APOE-ε3/ε4 genotype, especially in the age range of 60–70, the genetic risk for Alzheimer’s was highest in women.

Heavy Metal Detox In A Pill?
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 have previous discussed assorted approaches to “detoxing”:
Detox: What’s Real, What’s Not, What’s Useful, What’s Dangerous?
Today we’re going to be looking at one we didn’t cover there, which is zeolite.
What is zeolite?
Zeolite is a mineral that occurs naturally and can also be synthesized, and it’s famous for absorbing other stuff from around it. Because of this property, it’s used in many things, including:
- Petrochemical catalysis
- Water treatment
- Nuclear waste reprocessing
- Cat litter
- Supplements (for detox purposes)
That’s, uh… An interesting list, isn’t it? So, we were curious as to whether this mineral that’s also used in fish tank filters is, in fact, overpriced gravel being sold to the gullible as a health supplement.
We had to do some digging on this one
Our journey didn’t start well, with this very dubious-looking paper being cited by a company selling zeolite supplements:
This immediately prompted two questions:
- Who is eating graphene?!* That stuff does not occur in nature (or at least; it hasn’t ever been found; the universe is a big place so it might exist elsewhere), has only relatively recently been synthesized, is very difficult to produce, is two-dimensional while being hard as diamonds, and exists only in truly tiny lab-made quantities worldwide. It would be orders of magnitude easier to find and eat uranium.
- Is this a reputable journal? Which question was easier to answer than the former one, and the answer is “no”; we hadn’t heard of this journal (ACTA Scientific), and neither it seems had most of the Internet, but we did find it on a list of predatory journals, here.
*The citation given in the above paper should by rights answer the question of who is eating graphene, since by rights they must have demonstrated it somehow, but it just doesn’t. Instead, it links to what it claims is a paper titled “Oxygenated Zeolite (Clinoptilite) Efficiently Removes Aluminum & Graphene Oxide”, but is in reality just someone’s blog post with a screenshot of an actual paper entitled “Novel, oxygenated clinoptilolite material efficiently removes aluminium from aluminium chloride-intoxicated rats in vivo”). Looking up this real paper in its real journal, it does not mention graphene.
All this to say: sometimes, unscrupulous people will just plain lie to you, which is why peer review is important, as is sourcing data from reputable journals. Which is what we do for you so that you don’t have to 🙂
It does, actually, work though (for heavy metal detox)
Notwithstanding the aforementioned bunk, we found this from a more reputable publisher:
❝In this study, we have presented clinical evidence supporting the use of an activated clinoptilolite (zeolite) suspension to safely and effectively increase the urinary excretion of potentially toxic heavy metals in healthy volunteers without negatively impacting the electrolyte profiles of the participants.
Significant increases in the urinary excretion of aluminum, antimony, arsenic, bismuth, cadmium, lead, mercury, nickel and tin were observed in the subjects participating in the two study groups as compared to placebo controls.❞
Also good for the gut and against inflammation
Specifically, it’s good for gut barrier integrity, i.e., against “leaky gut syndrome”:
❝Twelve weeks of zeolite supplementation exerted beneficial effects on intestinal wall integrity as indicated via decreased concentrations of the tight junction modulator zonulin.
This was accompanied by mild anti-inflammatory effects in this cohort of aerobically trained subjects.❞
May also be good against neurodegenerative diseases
If it is (which is plausible), it’ll probably because of removing heavy metals and improving gut barrier integrity—in other words, the things we just looked at in the two reputable peer-reviewed studies we examined above.
But the science is young for this one; here’s the current state of things:
Zeolite and Neurodegenerative Diseases
Is it safe?
Safety reviews have found it to be safe, for example:
Critical Review on Zeolite Clinoptilolite Safety and Medical Applications in vivo
However, if you are taking regular medications, we recommend checking with your pharmacist or doctor to ensure that zeolite will not also remove those medications from your system!

The Lupus Solution – by Dr. Tiffany Caplan & Dr. Brent Caplan
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.
Lupus is not fun, and this book sets out to make it easier.
Starting off by explaining the basics of autoimmunity and how lupus works, the authors go on the address the triggers of lupus and how to avoid them—which if you’ve been suffering from lupus for a while, you probably know this part already, but it’s as well to give them a look over just in case you missed something.
The real value of the book though comes in the 8 chapters of the section “Tools & Therapies” which are mostly lifestyle adjustments though there are additionally some pharmaceutical approaches that can also help, and they are explained too. And no, it’s not just “reduce inflammation” (but yes, also that); rather, a whole array of things are examined that often aren’t thought of as related to lupus, but in fact can have a big impact.
The style is to-the-point and informational, and formatted for ease of reading. It doesn’t convey more hard science than necessary, but it does have a fair bibliography at the back.
It’s a short book, weighing in at 182 pages. If you want something more comprehensive, check out our review of The Lupus Encyclopedia, which is 848 pages of information-dense text and diagrams.
Bottom line: if you have lupus and would like fewer symptoms, this book can help you with that quite a bit without getting so technical as the aforementioned encyclopedia.
