Saturated Fat: What’s The Truth?
We asked you for your health-related opinion of saturated fat, and got the above-pictured, below-described, set of results.
- Most recorded votes were for “Saturated fat is good, but only some sources, and/or in moderation”
- This is an easy one to vote for, because of the “and/or in moderation” part, which tends to be a “safe bet” for most things.
- Next most popular was “Saturated fat is terrible for the health and should be avoided”
- About half as many recorded votes were for “I’m not actually sure what makes saturated fat different”, which is a very laudable option to click. Admitting when we don’t know things (and none of us know everything) is a very good first step to learning about them!
- Fewest recorded votes were for “Saturated fat is the best source of energy; we should get plenty”.
So, what does the science say?
First, a bit of physics, chemistry, and biology
You may be wondering what, exactly, saturated fats are “saturated” with. That’s a fair question, so…
All fats have a molecular structure made up of carbon, hydrogen, and oxygen atoms. Saturated fats are saturated with hydrogen, and thus have only single bonds between carbon atoms (unsaturated fats have at least one double-bond between carbon atoms).
The observable effect this has on them, is that fats that are saturated with hydrogen are solid at room temperature, whereas unsaturated fats are liquid at room temperature. Their different properties also make for different interactions inside the human body, including how likely or not they are to (for example) clog arteries.

Saturated fat is the best source of energy; we should get plenty: True or False?
False, in any reasonable interpretation, anyway. That is to say, if your idea of “plenty” is under 13g (e.g: two tablespoons of butter, and no saturated fat from other sources, e.g. meat) per day, then yes, by all means feel free to eat plenty. More than that, though, and you might want to consider trimming it down a bit.
The American Heart Association has this to say:
❝When you hear about the latest “diet of the day” or a new or odd-sounding theory about food, consider the source.
The American Heart Association recommends limiting saturated fats, which are found in butter, cheese, red meat and other animal-based foods, and tropical oils.
Decades of sound science has proven it can raise your “bad” cholesterol and put you at higher risk for heart disease.❞
Source: The American Heart Association Diet and Lifestyle Recommendations on Saturated Fat
The British Heart Foundation has a similar statement:
❝Despite what you read in the media, our advice is clear: replace saturated fats with unsaturated fats and avoid trans fats. Saturated fat is the kind of fat found in butter, lard, ghee, fatty meats and cheese. This is linked to an increased risk of heart and circulatory disease❞
Source: British Heart Foundation: What does fat do and what is saturated fat?
As for the World Health Organization:
❝1. WHO strongly recommends that adults and children reduce saturated fatty acid intake to 10% of total energy intake
2. WHO suggests further reducing saturated fatty acid intake to less than 10% of total energy intake
3. WHO strongly recommends replacing saturated fatty acids in the diet with polyunsaturated fatty acids; monounsaturated fatty acids from plant sources; or carbohydrates from foods containing naturally occurring dietary fibre, such as whole grains, vegetables, fruits and pulses.❞
Source: Saturated fatty acid and trans-fatty acid intake for adults and children: WHO guideline
Please note, organizations such as the AHA, the BHF, and the WHO are not trying to sell us anything, and just would like us to not die of heart disease, the world’s #1 killer.
As for “the best source of energy”…
We evolved to eat (much like our nearest primate cousins) a diet consisting mostly of fruits and other edible plants, with a small supplementary amount of animal-source protein and fats.
That’s not to say that because we evolved that way we have to eat that way—we are versatile omnivores. But for example, we are certainly not complete carnivores, and would quickly sicken and die if we tried to live on only meat and animal fat (we need more fiber, more carbohydrates, and many micronutrients that we usually get from plants)
The closest that humans tend to come to doing such is the ketogenic diet, which focuses on a high fat, low carbohydrate imbalance, to promote ketosis, in which the body burns fat for energy.
The ketogenic diet does work, and/but can cause a lot of health problems if a lot of care is not taken to avoid them.
See for example: 7 Keto Risks To Keep In Mind
Saturated fat is terrible for the health and should be avoided: True or False?
False, if we are talking about “completely”.
Firstly, it’s practically impossible to cut out all saturated fats, given that most dietary sources of fat are a mix of saturated, unsaturated (mono- and poly-), and trans fats (which are by far the worst, but beyond the scope of today’s main feature).
Secondly, a lot of research has been conducted and found insignificant or inconclusive results, in cases where saturated fat intake was already within acceptable levels (per the recommendations we mentioned earlier), and then cut down further.
Rather than fill up the newsletter with individual studies of this kind here’s a high-quality research review, looking at 19 meta-analyses, each of those meta-analyses having looked at many studies:
Dietary saturated fat and heart disease: a narrative review
Saturated fat is good, but only some sources, and/or in moderation: True or False?
True! The moderation part is easy to guess, so let’s take a look at the “but only some sources”.
We were not able to find any convincing science to argue for health-based reasons to favor plant- or animal-sourced saturated fat. However…
Not all saturated fats are created equal (there are many kinds), and also many of the foods containing them have additional nutrients, or harmful compounds, that make a big difference to overall health, when compared gram-for-gram in terms of containing the same amount of saturated fat.
For example:
- Palm oil’s saturated fat contains a disproportionate amount of palmitic acid, which raises LDL (“bad” cholesterol) without affecting HDL (“good” cholesterol), thus having an overall heart-harmful effect.
- Most animal fats contain a disproportionate amount of stearic acid, which has statistically insignificant effects on LDL and HDL levels, and thus is broadly considered “heart neutral” (in moderation!)
- Coconut oil’s saturated fat contains a disproportionate amount of lauric acid, which raises total cholesterol, but mostly HDL without affecting LDL, thus having an overall heart-beneficial effect (in moderation!)

Glucose Revolution – by Jessie Inchauspé
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.
While we all know that keeping balanced blood sugars is important for all us (be we diabetic, pre-diabetic, or not at all), it can be a mystifying topic!
Beyond a generic “sugar is bad”…
- What does it all mean and how does it all work?
- Should we go low-carb?
- What’s the deal with fruit?
- Carbs or protein for breakfast?
- Is “quick energy” ever a good thing?
- How do starches weigh in again?
It’s all so confusing!
Happily, Jessie Inchauspé has the incredible trifecta of qualifications to help us: she’s a biochemist, a keen cook, and a great educator. What we mean by this latter is:
Instead of dry textbook explanations, or “trust me” hand-waives, she explains biochemistry in a clear, simple, digestible (if you’ll pardon the pun) way with very helpful diagrams what things cause (or flatten) blood sugar spikes and how and why. If you read this book, you will understand, without guesswork or gaps, exactly what is happening on a physical level, and why and how her “10 hacks” work.
Her “10 hacks” are explained so thoroughly that each gets a chapter of its own, but we’ll not keep them a mystery from you meanwhile, they are:
- Eat foods in the right order
- Add a green starter to your meals
- Stop counting calories
- Flatten your breakfast curve
- Have any type of sugar you like—they’re all the same
- Pick dessert over a sweet snack
- Reach for the vinegar before you eat
- After you eat, move
- If you have to snack, go savoury
- Put some clothes on your carbs
She then finishes up with a collection of handy cheat-sheets and some of her own recipes.
Bottom line: this isn’t just a “how-to” book. It gives the how-to, yes, but it also gives such good explanations that you’ll never be confused again by what’s going on in your glucose-related health.

How Are You?
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.
Answering The Most Difficult Question: How Are You?
Today’s feature is aimed at helping mainly two kinds of people:
- “I have so many emotions that I don’t always know what to do with them”
- “What is an emotion, really? I think I felt one some time ago”
So, if either those describe you and/or a loved one, read on…
Alexithymia
Alexi who? Alexithymia is an umbrella term for various kinds of problems with feeling emotions.
That could be “problems feeling emotions” as in “I am unable to feel emotions” or “problems feeling emotions” as in “feeling these emotions is a problem for me”.
It is most commonly used to refer to “having difficulty identifying and expressing emotions”.
There are a lot of very poor quality pop-science articles out there about it, but here’s a decent one with good examples and minimal sensationalist pathologization:
Alexithymia Might Be the Reason It’s Hard to Label Your Emotions
A somatic start
Because a good level of self-awareness is critical for healthy emotional regulation, let’s start there. We’ll write this in the first person, but you can use it to help a loved one too, just switching to second person:
Simplest level first:
Are my most basic needs met right now? Is this room a good temperature? Am I comfortable dressed the way I am? Am I in good physical health? Am I well-rested? Have I been fed and watered recently? Does my body feel clean? Have I taken any meds I should be taking?
Note: If the answer is “no”, then maybe there’s something you can do to fix that first. If the answer is “no” and also you can’t fix the thing for some reason, then that’s unfortunate, but just recognize it anyway for now. It doesn’t mean the thing in question is necessarily responsible for how you feel, but it’s good to check off this list as a matter of good practice.
Bonus question: it’s cliché, but if applicable… What time of the month is it? Because while hormonal mood swings won’t create moods out of nothing, they sure aren’t irrelevant either and should be listened to too.
Bodyscanning next
What do you feel in each part of your body? Are you clenching your jaw? Are your shoulders tense? Do you have a knot in your stomach? What are your hands doing? How’s your posture? What’s your breathing like? How about your heart? What are your eyes doing?
Your observations at this point should be neutral, by the way. Not “my posture is terrible”, but “my posture is stooped”, etc. Much like in mindfulness meditation, this is a time for observing, not for judging.
Narrowing it down
Now, like a good scientist, you have assembled data. But what does the data mean for your emotions? You may have to conduct some experiments to find out.
Thought experiments: what calls to you? What do you feel like doing? Do you feel like curling up in a ball? Breaking something? Taking a bath? Crying?
Maybe what calls to you, or what you feel like doing, isn’t something that’s possible for you to do. This is often the case with anxiety, for example, and perhaps also guilt. But whatever calls to you, notice it, reflect on it, and if it’s something that your conscious mind considers reasonable and safe for you to do, you can even try doing it.
Your body is trying to help you here, by the way! It will try (and usually succeed) to give you a little dopamine spike when you anticipate doing the thing it wants you to do. Warning: it won’t always be right about what’s best for you, so do still make your own decisions about whether it is a good idea to safely do it.
Practical experiments: whether you have a theory or just a hypothesis (if you have neither make up a hypothesis; that is also what scientists do), you can also test it:
If in the previous step you identified something you’d like to do and are able to safely do it, now is the time to try it. If not…
- Find something that is likely to (safely) tip you into emotional expression, ideally, in a cathartic way. But, whatever you can get is good.
- Music is great for this. What songs (or even non-lyrical musical works) make you sad, happy, angry, energized? Try them.
- Literature and film can be good too, albeit they take more time. Grab that tear-jerker or angsty rage-fest, and see if it feels right.
- Other media, again, can be completely unrelated to the situation at hand, but if it evokes the same emotion, it’ll help you figure out “yes, this is it”.
- It could be a love letter or a tax letter, it could be an outrage-provoking news piece or some nostalgic thing you own.
Ride it out, wherever it takes you (safely)
Feelings feel better felt. It doesn’t always seem that way! But, really, they are.
Emotions, just like physical sensations, are messengers. And when a feeling/sensation is troublesome, one of the best ways to get past it is to first fully listen to it and respond accordingly.
- If your body tells you something, then it’s good to acknowledge that and give it some reassurance by taking some action to appease it.
- If your emotions are telling you something, then it’s good to acknowledge that and similarly take some action to appease it.
There is a reason people feel better after “having a good cry”, or “pounding it out” against a punchbag. Even stress can be dealt with by physically deliberately tensing up and then relaxing that tension, so the body thinks that you had a fight and won and can relax now.
And when someone is in a certain (not happy) mood and takes (sometimes baffling!) actions to stay in that mood rather than “snap out of it”, it’s probably because there’s more feeling to be done before the body feels heard. Hence the “ride it out if you safely can” idea.
How much feeling is too much?
While this is in large part a subjective matter, clinically speaking the key question is generally: is it adversely affecting daily life to the point of being a problem?
For example, if you have to spend half an hour every day actively managing a certain emotion, that’s probably indicative of something unusual, but “unusual” is not inherently pathological. If you’re managing it safely and in a way that doesn’t negatively affect the rest of your life, then that is generally considered fine, unless you feel otherwise about it.
If you do think “I would like to not think/feel this anymore”, then there are tools at your disposal too:
- How To Manage Chronic Stress
- How To Set Anxiety Aside
- How To Stop Revisiting Those Memories
- How To Stay Alive (When You Really Don’t Want To)
Take care!

Dr. Kim Foster’s Method For Balancing Hormones Naturally
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.
Not just sex hormones, but also hormones like cortisol (the stress hormone), and thyroid hormones (for metabolism regulation) too! The body is most of the time self-regulating when it comes to hormones, but there are things that we can do to help our body look after us correctly.
In short, if we give our body what it needs, it will (usually, barring serious illness!) give us what we need.
Dr. Foster recommends…
Foods:
- Healthy fats (especially avocados and nuts)
- Lean proteins (especially poultry, fish, and legumes)
- Fruits & vegetables (especially colorful ones)
- Probiotics (especially fermented foods like sauerkraut, kimchi, etc)
- Magnesium-rich foods (especially dark leafy greens, nuts, and yes, dark chocolate)
Teas:
- Camomile tea (especially beneficial against cortisol overproduction)
- Nettle tea (especially beneficial for estrogen production)
- Peppermint tea (especially beneficial for gut health, thus indirect hormone benefits)
Stress reduction:
- Breathing exercises (especially mindfulness exercises)
- Yoga (especially combining exercise with stretches)
- Spending time in nature (especially green spaces)
Dr. Foster explains more about all of these things, along with more illustrative examples, so if you can, do enjoy her video:

Elderberries vs Cranberries – 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 elderberries to cranberries, we picked the elderberries.
Why?
In terms of macros, elderberry has slightly more carbs and 2x the fiber, the ratio of which gives elderberries the lower glycemic index also. A win for elderberries, then.
Looking at the vitamins, elderberries have more of vitamins A, B1, B2, B3, B6, B9, and C, while cranberries have more vitamin B5. An easy win for elderberries in this category.
In the category of minerals, we see a similar story: elderberries have more calcium, copper, iron, phosphorus, potassium, selenium, and zinc, while cranberries have (barely) more magnesium. Another clear win for elderberries.
Both of these fruits have additional “special” properties, and it’s worth noting that:
- elderberries’ bonus properties include that they significantly hasten recovery from upper respiratory tract viral infections.
- cranberries’ bonus properties (including: famously very good at reducing UTI risk) come with some warnings, including that they may increase the risk of kidney stones if you are prone to such, and also that cranberries have anti-clotting effects, which are great for heart health but can be a risk of you’re on blood thinners or have a bleeding disorder.
You can read about both of these fruits’ special properties in more detail below:

The Sugar Alcohol That Reduces BMI!
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.
Inositol Does-It-Ol’!
First things first, a quick clarification up-front:
Myo-inositol or D-chiro-inositol?
We’re going to be talking about inositol today, which comes in numerous forms, but most importantly:
- Myo-inositol (myo-Ins)
- D-chiro-inositol (D-chiro-Ins)
These are both inositol, (a sugar alcohol!) and for our purposes today, the most relevant form is myo-inositol.
The studies we’ll look at today are either:
- just about myo-inositol, or
- about myo-inositol in the presence of d-chiro-inositol at a 40:1 ratio.
You have both in your body naturally; wherever supplementation is mentioned, it means supplementing with either:
- extra myo-inositol (because that’s the one the body more often needs more of), or
- both, at the 40:1 ratio that we mentioned above (because that’s one way to help balance an imbalanced ratio)
With that in mind…
Inositol against diabetes?
Inositol is known to:
- decrease insulin resistance
- increase insulin sensitivity
- have an important role in cell signaling
- have an important role in metabolism
The first two things there both mean that inositol is good against diabetes. It’s not “take this and you’re cured”, but:
- if you’re pre-diabetic it may help you avoid type 2 diabetes
- if you are diabetic (either type) it can help in the management of your diabetes.
It does this by allowing your body to make better use of insulin (regardless of whether that insulin is from your pancreas or from the pharmacy).
How does it do that? Research is still underway and there’s a lot we don’t know yet, but here’s one way, for example:
❝Evidence showed that inositol phosphates might enhance the browning of white adipocytes and directly improve insulin sensitivity through adipocytes❞
Read: Role of Inositols and Inositol Phosphates in Energy Metabolism
We mentioned its role in metabolism in a bullet-point above, and we didn’t just mean insulin sensitivity! There’s also…
Inositol for thyroid function?
The thyroid is one of the largest endocrine glands in the body, and it controls how quickly the body burns energy, makes proteins, and how sensitive the body should be to other hormones. So, it working correctly or not can have a big impact on everything from your mood to your weight to your energy levels.
How does inositol affect thyroid function?
- Inositol has an important role in thyroid function and dealing with autoimmune diseases.
- Inositol is essential to produce H2O2 (yes, really) required for the synthesis of thyroid hormones.
- Depletion of inositol may lead to the development of some thyroid diseases, such as hypothyroidism.
- Inositol supplementation seems to help in the management of thyroid diseases.
Read: The Role of Inositol in Thyroid Physiology and in Subclinical Hypothyroidism Management
Inositol for PCOS?
A systematic review published in the Journal of Gynecological Endocrinology noted:
- Inositol can restore spontaneous ovarian activity (and consequently fertility) in most patients with PCOS.
- Myo-inositol is a safe and effective treatment to improve:
- ovarian function
- healthy metabolism
- healthy hormonal balance
While very comprehensive (which is why we included it here), that review’s a little old, so…
Check out this cutting edge (Jan 2023) study whose title says it all:
Inositol for fertility?
Just last year, Mendoza et al published that inositol supplementation, together with antioxidants, vitamins, and minerals, could be an optimal strategy to improve female fertility.
This built from Gambiole and Forte’s work, which laid out how inositol is a safe compound for many issues related to fertility and pregnancy. In particular, several clinical trials demonstrated that:
- inositol can have therapeutic effects in infertile women
- inositol can also be useful as a preventive treatment during pregnancy
- inositol could prevent the onset of neural tube defects
- inositol also reduces the occurrence of gestational diabetes
Due to the safety and efficiency of inositol, it can take the place of many drugs that are contraindicated in pregnancy. Basically: take this, and you’ll need fewer other drugs. Always a win!
Read: Myo-Inositol as a Key Supporter of Fertility and Physiological Gestation
Inositol For Weight Loss
We promised you “this alcohol sugar can reduce your BMI”, and we weren’t making it up!
Zarezadeh et al conducited a very extensive systematic review, and found:
- Oral inositol supplementation has positive effect on BMI reduction.
- Inositol in the form of myo-inositol had the strongest effect on BMI reduction.
- Participants with PCOS and/or who were overweight, experienced the most significant improvement of all.
Want some inositol?
As ever, we don’t sell it (or anything else), but for your convenience, here’s myo-inositol and d-chiro-inositol at a 40:1 ratio, available on Amazon!

Ikigai – by Héctor García and Francesc Miralles
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.
Ikigai is the Japanese term for what in English we often call “raison d’être”… in French, because English is like that.
But in other words: ikigai is one’s purpose in life, one’s reason for living.
The authors of this work spend some chapters extolling the virtues of finding one’s ikigai, and the health benefits that doing so can convey. It is, quite clearly, an important and relevant factor.
The rest of the book goes beyond that, though, and takes a holistic look at why (and how) healthy longevity is enjoyed by:
- Japanese people in general,
- Okinawans in particular,
- Residents of Okinawa’s “blue zone” village with the highest percentage of supercentenarians, most of all.
Covering considerations from ikigai to diet to small daily habits to attitudes to life, we’re essentially looking at a blueprint for healthy longevity.
For a book whose title and cover suggests a philosophy-heavy content, there’s a lot of science in here too, by the way! From microbiology to psychiatry to nutrition science to cancer research, this book covers all bases.
In short: this book gives a lot of good science-based suggestions for adjustments we can make to our lives, without moving to an Okinawan village!
