Our Verdict
When comparing hazelnuts to cashews, we picked the hazelnuts.
Why?
It’s close! This one’s interesting…
In terms of macros, hazelnuts have more fiber and fats, while cashews have more protein and carbs. All in all, all good stuff all around; maybe a win for one or the other depending on your priorities. We’d pick hazelnuts here, but your preference may vary.
When it comes to vitamins, hazelnuts have more of vitamins A, B1, B2, B3, B5, B6, B9, C, and E, while cashews have more vitamin K. An easy win for hazelnuts here, and the margins weren’t close.
In the category of minerals, hazelnuts have more calcium, manganese, and potassium, while cashews have more copper, iron, magnesium, phosphorus, selenium, and zinc. This is a win for cashews, but it’s worth noting that cup for cup, both of these nuts provide more than the daily requirement of most of those minerals. This means that in practical terms, it doesn’t matter too much that (for example), while cashews provide 732% of the daily requirement for copper, hazelnuts “only” provide 575%. So while this category remains a victory for cashews, it’s something of a “on paper” thing for the most part.
Adding up the sections (ambivalent + clear win for hazelnuts + nominal win for cashews) means that in total today we’re calling it in favour of hazelnuts… But as ever, enjoy both, because both are good and so is diversity!

Staying Alive – by Dr. Jenny Goodman
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.
A lot of “healthy long life” books are science-heavy to the point of being quite challenging to read—they become excellent reference sources, but not exactly “curl up in the armchair” books.
Dr. Goodman writes in a much more reader-friendly fashion, casual yet clear.
She kicks off with season-specific advice. What does that mean? Basically, our bodies need different things at different times of year, and we face different challenges to good health. We may ignore such at our peril!
After a chapter for each of the four seasons (assuming a temperate Northern Hemisphere climate), she goes on to cover the seasons of our life. Once again, our bodies need different things at different times in our life, and we again face different challenges to good health!
There’s plenty of “advice for all seasons”, too. Nutritional dos and don’t, and perennial health hazards to avoid.
As a caveat, she does also hold some unscientific views that may be skipped over. These range from “plant-based diets aren’t sustainable” to “this detox will get rid of heavy metals”. However, the value contained in the rest of the book is more than sufficient to persuade us to overlook those personal quirks.
In particular, she offers very good advice on overcoming cravings (and distinguishing them from genuine nutritional cravings), and taking care of our “trillions of tiny companions” (beneficial gut microbiota) without nurturing Candida and other less helpful gut flora and fauna.
In short, a fine lot of information in a very readable format.

The Bitter Truth About Coffee (or is it?)
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 Bitter Truth About Coffee (or is it?)
Yesterday, we asked you for your (health-related) views on coffee. The results were clear: if we assume the responses to be representative, we’re a large group of coffee-enthusiasts!
One subscriber who voted for “Coffee is a healthy stimulant, hydrating, and full of antioxidants” wrote:
❝Not so sure about how hydrating it is! Like most food and drink, moderation is key. More than 2 or 3 cups make me buzz! Just too much.❞
And that fine point brings us to our first potential myth:
Coffee is dehydrating: True or False?
False. With caveats…
Coffee, in whatever form we drink it, is wet. This may not come as a startling revelation, but it’s an important starting point. It’s mostly water. Water itself is not dehydrating.
Caffeine, however, is a diuretic—meaning you will tend to pee more. It achieves its diuretic effect by increasing blood flow to your kidneys, which prompts them to release more water through urination.
See: Effect of caffeine on bladder function in patients with overactive bladder symptoms
How much caffeine is required to have a diuretic effect? About 4.5 mg/kg.
What this means in practical terms: if you weigh 70kg (a little over 150lbs), 4.5×70 gives us 315.
315mg is about how much caffeine might be in six shots of espresso. We say “might” because while dosage calculations are an exact science, the actual amount in your shot of espresso can vary depending on many factors, including:
- The kind of coffee bean
- How and when it was roasted
- How and when it was ground
- The water used to make the espresso
- The pressure and temperature of the water
…and that’s all without looking at the most obvious factor: “is the coffee decaffeinated?”
If it doesn’t contain caffeine, it’s not diuretic. Decaffeinated coffee does usually contain tiny amounts of caffeine still, but with nearer 3mg than 300mg, it’s orders of magnitude away from having a diuretic effect.
If it does contain caffeine, then the next question becomes: “and how much water?”
For example, an Americano (espresso, with hot water added to make it a long drink) will be more hydrating than a ristretto (espresso, stopped halfway through pushing, meaning it is shorter and stronger than a normal espresso).
A subscriber who voted for “Coffee messes with sleep, creates dependency, is bad for the heart and gut, and is dehydrating too” wrote:
❝Coffee causes tachycardia for me so staying away is best. People with colon cancer are urged to stay away from coffee completely.❞
These are great points! It brings us to our next potential myth:
Coffee is bad for the heart: True or False?
False… For most people.
Some people, like our subscriber above, have an adverse reaction to caffeine, such as tachycardia. An important reason (beyond basic decency) for anyone providing coffee to honor requests for decaff.
For most people, caffeine is “heart neutral”. It doesn’t provide direct benefits or cause direct harm, provided it is enjoyed in moderation.
See also: Can you overdose on caffeine?
Some quick extra notes…
That’s all we have time for in myth-busting, but it’s worth noting before we close that coffee has a lot of health benefits; we didn’t cover them today because they’re not contentious, but they are interesting nevertheless:
- Coffee is the world’s biggest source of antioxidants
- 65% reduced risk of Alzheimer’s for coffee-drinkers
- 67% reduced risk of type 2 diabetes for coffee-drinkers
- 43% reduced risk of liver cancer for coffee-drinkers
- 53% reduced suicide risk for coffee-drinkers
Enjoy!

The Insider’s Guide To Making Hospital As Comfortable As Possible
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.
Nobody Likes Surgery, But Here’s How To Make It Much Less Bad
This is Dr. Chris Bonney. He’s an anesthesiologist. If you have a surgery, he wants you to go in feeling calm, and make a quick recovery afterwards, with minimal suffering in between.
Being a patient in a hospital is a bit like being a passenger in an airplane:
- Almost nobody enjoys the thing itself, but we very much want to get to the other side of the experience.
- We have limited freedoms and comforts, and small things can make a big difference between misery and tolerability.
- There are professionals present to look after us, but they are busy and have a lot of other people to tend to too.
So why is it that there are so many resources available full of “tips for travelers” and so few “tips for hospital patients”?
Especially given the relative risks of each, and likelihood, or even near-certainty of coming to at least some harm… One would think “tips for patients” would be more in demand!
Tips for surgery patients, from an insider expert
First, he advises us: empower yourself.
Empowering yourself in this context means:
- Relax—doctors really want you to feel better, quickly. They’re on your side.
- Research—knowledge is power, so research the procedure (and its risks!). Dr. Bonney, himself an anesthesiologist, particularly recommends you learn what specific anesthetic will be used (there are many, and they’re all a bit different!), and what effects (and/or after-effects) that may have.
- Reframe—you’re not just a patient; you’re a customer/client. Many people suffer from MDeity syndrome, and view doctors as authority figures, rather than what they are: service providers.
- Request—if something would make you feel better, ask for it. If it’s information, they will be not only obliged, but also enthusiastic, to give it. If it’s something else, they’ll oblige if they can, and the worst case scenario is something won’t be possible, but you won’t know if you don’t ask.
Next up, help them to help you
There are various ways you can be a useful member of your own care team:
- Go into surgery as healthy as you can. If there’s ever a time to get a little fitter, eat a little healthier, prioritize good quality sleep more, the time approaching your surgery is the time to do this.
- This will help to minimize complications and maximize recovery.
- Take with you any meds you’re taking, or at least have an up-to-date list of what you’re taking. Dr. Bonney has very many times had patients tell him such things as “Well, let me see. I have two little pink ones and a little white one…” and when asked what they’re for they tell him “I have no idea, you’d need to ask my doctor”.
- Help them to help you; have your meds with you, or at least a comprehensive list (including: medication name, dosage, frequency, any special instructions)
- Don’t stop taking your meds unless told to do so. Many people have heard that one should stop taking meds before a surgery, and sometimes that’s true, but often it isn’t. Keep taking them, unless told otherwise.
- If unsure, ask your surgical team in advance (not your own doctor, who will not be as familiar with what will or won’t interfere with a surgery).
Do any preparatory organization well in advance
Consider the following:
- What do you need to take with you? Medications, clothes, toiletries, phone charger, entertainment, headphones, paperwork, cash for the vending machine?
- Will the surgeons need to shave anywhere, and if so, might you prefer doing some other form of depilation (e.g. waxing etc) yourself in advance?
- Is your list of medications ready?
- Who will take you to the hospital and who will bring you back?
- Who will stay with you for the first 24 hours after you’re sent home?
- Is someone available to look after your kids/pets/plants etc?
Be aware of how you do (and don’t) need to fast before surgery
The American Society of Anesthesiologists gives the following fasting guidelines:
- Non-food liquids: fast for at least 2 hours before surgery
- Food liquids or light snacks: fast for at least 6 hours before surgery
- Fried foods, fatty foods, meat: fast for at least 8 hours before surgery
(see the above link for more details)
Dr. Bonney notes that many times he’s had patients who’ve had the worst thirst, or caffeine headache, because of abstaining unnecessarily for the day of the surgery.
Unless told otherwise by your surgical team, you can have black coffee/tea up until two hours before your surgery, and you can and should have water up until two hours before surgery.
Hydration is good for you and you will feel the difference!
Want to know more?
Dr. Bonney has his own website and blog, where he offers lots of advice, including for specific conditions and specific surgeries, with advice for before/during/after your hospital stay.
He also has a book with many more tips like those we shared today:

How To Avoid Age-Related Macular Degeneration
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.
Avoiding Age-Related Macular Degeneration
Eye problems can strike at any age, but as we get older, it becomes a lot more likely. In particular, age-related macular degeneration is, as the name suggests, an age-bound disease.
Is there no escaping it, then?
The risk factors for age-related macular degeneration are as follows:
- Being over the age of 55 (can’t do much about this one)
- Being over the age of 65 (risk climbs sharply now)
- Having a genetic predisposition (can’t do much about this one)
- Having high cholesterol (this one we can tackle)
- Having cardiovascular disease (this one we can tackle)
- Smoking (so, just don’t)
Genes predispose; they don’t predetermine. Or to put it another way: genes load the gun, but lifestyle pulls the trigger.
Preventative interventions against age-related macular degeneration
Prevention is better than a cure in general, and this especially goes for things like age-related macular degeneration, because the most common form of it has no known cure.
So first, look after your heart (because your heart feeds your eyes).
See also: The Mediterranean Diet
Next, eat to feed your eyes specifically. There’s a lot of research to show that lutein helps avoid age-related diseases in the eyes and the rest of the brain, too:
See also: Brain Food? The Eyes Have It
Do supplements help?
They can! There was a multiple-part landmark study by the National Eye Institute, a formula was developed that reduced the 5-year risk of intermediate disease progressing to late disease by 25–30%. It also reduced the risk of vision loss by 19%.
You can read about both parts of the study here:
Age-Related Eye Disease Studies (AREDS/AREDS2): major findings
As you can see, an improvement was made between the initial study and the second one, by replacing beta-carotene with lutein and zeaxanthin.
The AREDS2 formula contains:
- 500 mg vitamin C
- 180 mg vitamin E
- 80 mg zinc
- 10 mg lutein
- 2 mg copper
You can learn more about these supplements, and where to get them, here on the NEI’s corner of the official NIH website:

Reclaiming Body Trust – by Hilary Kinavey & Dana Sturtevant
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.
Authored by a therapist and a dietician, this book draws from both of their extensive professional clinical experiences, to explore how we can (often early in our lives) be led into disordered thinking when it comes to food and our bodies, and how we can “take back that which has been stolen from us”.
More prosaically: the presented goal here is for us to each figure out where we are with our own body, and how we might build our relationship with same going forwards, in the way that will work the best for us.
The style is relaxed and conversational, while taking care to cover topics that are often tricky with no less seriousness. Chapter headings such as “Your coping is rooted in wisdom”, “What does grief have to do with it?” and “Allowing for pleasure and satisfaction” give an idea of the flavors at hand here.
Bottom line: if you think your relationship with food and your body could be better, not only are you probably right, but also, this book can help.

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!
