Of the two authors, the former is a professional public speaker, and the latter is a professional dietician. As a result, we get a book that is polished and well-presented, while actually having a core of good solid science (backed up with plenty of references).
The book is divided into two parts; the first part has 9 chapters pertaining to 9 categories of superfood (with more details about top-tier examples of each, within), and the second part has 143 pages of recipes.
And yes, as usual, a couple of the recipes are “granola” and “smoothie”, but when are they not? Most of the recipes are worthwhile, though, with a lot of good dishes that should please most people.
Bottom line: this is half pop-science presentation of superfoods, and half cookbook featuring those ingredients. Definitely a good way to increase your consumption of superfoods, and get the most out of your diet.

Why Some Friendships Last And Others Don’t
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.
Friendships matter a lot, playing a significant role in our wellbeing, physical as well as mental. They bring additional meaning to our lives, help us cope with setbacks, and hopefully will be at our side through the highs and lows of life. And yet, for something that’s in principle good for everyone involved, there can be problems:
Friend to the end?
Firstly, some people find it harder to make (and then further deepen) friendships with others, which can be for a whole host of reasons.
Approaching new people can feel intimidating, but it’s a common struggle. Research shows that people often underestimate how much others enjoy their company, a phenomenon known as the “liking gap.” By reminding ourselves that others are likely to appreciate our presence and expecting to be well-received (the “acceptance prophecy”), we can approach social interactions with greater confidence.
As relationships grow, they often deepen through companionship and closeness:
- Companionship arises from shared hobbies, interests, or values, and it builds rapport.
- Closeness involves sharing thoughts, feelings, and experiences, which can build intimacy together.
An important key to these is consistency, which—whether through regular chats, honoring plans, or showing support—helps strengthen bonds, even in long-distance friendships (something often considered a barrier to closeness).
Even the strongest friendships can face challenges, of course. Conflicts may arise from a lack of support during difficult moments, or worse, betrayal. Or it could all be a misunderstanding. These situations are best addressed through honest, non-judgmental conversations. Avoiding defensiveness or accusations, and instead focusing on sharing feelings and understanding the other person’s perspective, can turn these tough discussions into opportunities for growth and stronger connections.

10 Oft-Ignored Symptoms Of Diabetes
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.
Due in part to its prevalence and manageability, diabetes is often viewed as more of an inconvenience than an existential threat. While very few people in countries with decent healthcare die of diabetes directly (such as by diabetic ketoacidosis, which is very unpleasant, and happens disproportionately in the US where insulin is sold with a 500%–3000% markup in price compared to other countries), many more die of complications arising from comorbidities, and as for what comorbidities come with diabetes, well, it increases your risk for almost everything.
So, while for most people diabetes is by no means a death sentence, it is something that means you’ll now have to watch out for pretty much everything else too. On which note, Dr. Siobhan Deshauer is here with things to be aware of:
More than your waistline
Some of these are early symptoms (even appearing in the prediabetic stage, so can be considered an early warning for diabetes), some are later risks (it’s unlikely you’ll lose your feet from diabetic neuropathy complications before noticing that you are diabetic), but all and any of them are good reason to speak with your doctor sooner rather than later:
- Polyuria: waking up multiple times at night to urinate due to excess glucose spilling into the urine.
- Increased thirst: dehydration from frequent urination leads to excessive thirst, creating a cycle.
- Acanthosis nigricans: dark, velvety patches on areas like the neck, armpits, or groin, signalling insulin resistance.
- Skin tags: multiple skin tags in areas of friction may indicate insulin resistance.
- Recurrent Infections: high blood sugar weakens the immune system, making skin infections, UTIs, and yeast infections more common.
- Diabetic stiff hand syndrome: stiffness in hands, limited movement, or a “positive prayer sign” caused by sugar binding to skin and tendon proteins.
- Frozen shoulder and trigger finger: pain and limited movement in the shoulder or fingers, with a snapping sensation when moving inflamed tendons.
- Neuropathy: numbness, tingling, or pain in hands and feet due to nerve and blood vessel damage, often leading to foot deformities like Charcot foot.
- Diabetic foot infections: poor sensation, weakened immune response, and slow healing can result in severe infections and potential amputations.
- Gastroparesis: damage to stomach nerves causes delayed digestion, leading to bloating, nausea, and erratic blood sugar levels.

The Sucralose News: Scaremongering Or Serious?
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.
What’s the news on sucralose?
These past days the press has been abuzz with frightening tales:
- This Common Artificial Sweetener Can Break Down DNA, Scientists Warn
- Sucralose Damages DNA, Linked to Leaky Gut
- Chemical found in common sweetener damages DNA
- Chemical found in widely used sweetener breaks up DNA
- Chemical from Splenda breaks up DNA
How true and/or serious is this?
Firstly, let’s manage expectations. Pineapple juice also breaks down DNA, but is not generally considered a health risk. So let’s keep that in mind, while we look into the science.
Is sucralose as scary as pineapple juice, or is it something actually dangerous?
The new study (that sparked off these headlines)
The much-referenced study is publicly available to read in full—here it is:
You may notice that this doesn’t have quite the snappy punchiness of some of the headlines, but let’s break this down, if you’ll pardon the turn of phrase:
- Toxicological: pertaining to whether or not it has toxic qualities
- Pharmacokinetic: the science of asking, of chemicals in bodies, “where did it come from; where did it go; what could it do there; what can we know?”
- Sucralose-6-acetate: an impurity that can be found in sucralose. For perspective, the study found that the sucralose in Splenda contained “up to” 0.67% sucralose-6-acetate.
- Sucralose: a modified form of sucrose, that makes it hundreds of times sweeter, and non-caloric because the body cannot break it down so it’s treated as a dietary fiber and just passes through
- In vitro: things are happening in petri dishes, not in animals (human or otherwise), which would be called “in vivo”
- Screening assays: “we set up a very closed-parameters chemical test, to see what happens when we add this to this” ⇽ oversimplification, but this is the basic format of a screening assay
Great, now we understand the title, but what about the study?
Researchers looked primarily at the effects of sucralose-6-acetate and sucralose (together and separately) on epithelial cells (these are very simple cells that are easy to study; conveniently, they are also most of what makes up our intestinal walls). For this, they used a fancy way of replicating human intestinal walls, that’s actually quite fascinating but beyond the scope of today’s newsletter. Suffice it to say: it’s quite good, and/but has its limitations too. They also looked at some in vivo rat studies.
What they found was…
Based on samples from the rat feces (somehow this didn’t make it into the headlines), it appears that sucralose may be acetylated in the intestines. What that means is that we, if we are like the rats (definitely not a given, but a reasonable hypothesis), might convert up to 10% of sucralose into sucralose-6-acetate inside us. Iff we do, the next part of the findings become more serious.
Based on the in vitro simulations, both sucralose and sucralose-6-acetate reduced intestinal barrier integrity at least a little, but sucralose-6-acetate was the kicker when it came to most of the effects—at least, so we (reasonably!) suppose.
Basically, there’s a lot of supposition going on here but the suppositions are reasonable. That’s how science works; there’s usually little we can know for sure from a single study; it’s when more studies roll in that we start to get a more complete picture.
What was sucralose-6-acetate found to do? It increased the expression of genes associated with inflammation, oxidative stress, and cancer (granted those three things generally go together). So that’s a “this probably has this end result” supposition.
More concretely, and which most of the headlines latched onto, it was found (in vitro) to induce cytogenic damage, specifically, of the clastogenic variety (produces DNA strand breaks—so this is different than pineapple’s bromelain and DNA-helicase’s relatively harmless unzipping of genes).
The dose makes the poison
So, how much is too much and is that 0.67% something to worry about?
- Remembering the rat study, it may be more like 10% once our intestines have done their thing. Iff we’re like rats.
- But, even if it’s only 0.67%, this will still be above the “threshold of toxicological concern for genotoxicity”, of 0.15µg/person/day.
- On the other hand, the fact that these were in vitro studies is a serious limitation.
- Sometimes something is very dangerous in vitro, because it’s being put directly onto cells, whereas in vivo we may have mechanisms for dealing with that.
We won’t know for sure until we get in vivo studies in human subjects, and that may not happen any time soon, if ever, depending on the technical limitations and ethical considerations that sometimes preclude doing certain studies in humans.
Bottom line:
- The headlines are written to be scary, but aren’t wrong; their claims are fundamentally true
- What that means for us as actual humans may not be the same, however; we don’t know yet
- For now, it is probably reasonable to avoid sucralose just in case

Cherries vs Blueberries – 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 cherries to blueberries, we picked the blueberries.
Why?
It was close! And blueberries only won by virtue of taking an average value for cherries; we could have (if you’ll pardon the phrase) cherry-picked tart cherries for extra benefits that’d put them ahead of blueberries. That’s how close it is.
In terms of macros, they are almost identical, so nothing to set them apart there.
In the category of vitamins, they are mostly comparable except that blueberries have a lot more vitamin K, and cherries have a lot more vitamin A. Since vitamin K is the vitamin that’s scarcer in general, we’ll call blueberries’ vitamin K content a win.
Blueberries do also have about 6x more vitamin E, with a cup of blueberries containing about 10% of the daily requirement (and cherries containing almost none). Another small win for blueberries.
When it comes to minerals, they are mostly comparable; the largest point of difference is that blueberries contain more manganese while cherries contain more copper; nothing to decide between them here.
We’re down to counting amino acids and antioxidants now, so blueberries have a lot more cystine and tyrosine. They also have slightly more of amino acids that they both only have trace amounts of. And as for antioxidants? Blueberries contain notably more quercetin.
So, blueberries win the day—but if we had specified tart cherries rather than taking an average, they could have come out on top. Enjoy both!

What Is Earwax & Should You Get Rid Of 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.
Earwax (cerumen) forms in the outer ear canal when dead skin cells mix with oily sweat (a specialty of the apocrine glands) and sebum, a fatty substance mostly associated with facial oiliness. But, does it have a purpose, or is it just a waste product?
Nature is (mostly) best in this case
Earwax plays an important role in ear health, acting as a natural lubricant that prevents dryness and itchiness, trapping debris and microbes, and forming a protective barrier for the ear canal. It even contains proteins that help fight bacterial infections.
As for removal: the body has a natural mechanism for removing excess earwax: as skin cells grow, they migrate outward, carrying earwax with them.
In contrast, manual removal of earwax can do more harm than good. Using swabs or other items often pushes wax deeper, risks damaging the ear canal, and disrupts its protective barrier, potentially leading to infection.
Ear candling, which claims to extract earwax, not only does not work (its main premise has been actively disproven and clinical evidence shows unequivocally that it doesn’t work by any mysterious method either; it just plain doesn’t work), but also can cause injuries and will tend to leave more harmful debris behind than was there originally.
For those prone to earwax buildup, over-the-counter eardrops can help soften wax for natural removal, and medical professionals have safe methods to clear blockages if necessary.
To maintain ear health, it’s best to clean only the outer ear with a damp cloth, limit the use of earplugs or earbuds, and generally leave earwax alone unless it causes discomfort or hearing issues.

The Counterintuitive Dos and Don’ts of Nail Health

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
❝I take a vitamin supplement for strengthening my nails (particularly one of my big toes!) – but they are running out! What do you recommend for strengthening nails? What is/are the key ingredient(s)?❞
Vitamin-wise, biotin (vitamin B7) is an underrated and very important one. As a bonus, it’s really good for your hair too (hair and nails being made of fundamentally the same “stuff”. Because it has exceptionally low toxicity, it can be taken up to 10,000% of the NRV, so if shopping for supplements, a high biotin content is better than a low one.
A lot of products marketed as for “skin, hair, and nails” focus on vitamins A and E, which are good for the skin but aren’t so relevant for nails.
Nutritionally, getting plenty of protein (whatever form you normally take it is fine) is also important since keratin (as nails are made of) is a kind of protein.
Outside of nutritional factors, a few other considerations:
- Testosterone strengthens nails, and declining testosterone levels (as experienced by most men over the age of 45) can result in weaker nails. So for men over 45 especially, a diet that favors testosterone (think foods rich in magnesium and zinc) is good.
- Because estrogen doesn’t do for women’s nails what testosterone does for men’s nails, increasing our magnesium and zinc intake won’t help our nails (but it’s still good for other things, including energy levels in the day and good sleep at night, and most people are deficient in magnesium anyway)
- Those of us who enjoy painted nails would do well to let our nails go without polish sometimes, as it can dry them out. And, acrylic nails are truly ruinous to nail health, as are gel nails (the kind that use a UV lamp to harden them—which is also bad for the skin)
- When nails are brittle, it can be tempting to soak them to reduce their brittleness. However, this is actually counterproductive, as the water will leech nutrients from the nails, and by the time you’ve been out of the footbath (for example) for about an hour, your nails will bemore brittle than before you soaked them.
- Use a moisturizing lotion or nail-oil instead—bonus if it contains biotin, keratin, and/or other helpful nutrients.
- Keep yourself hydrated, too! Hydration that comes to your nails from the inside will deliver nutrients, rather than removing them.
About those supplements: we don’t sell them (or anything else) but for your convenience, here are some great ones (this writer takes pretty much the same, just a different brand because I’m in a different country):
Magnesium Gummies (600mg) & Biotin Gummies (10,000µg)
Enjoy!
