Many people know the signs of a heart attack when it’s happening, but how about before it’s too late to avoid it?
The signs
- Unusual fatigue: persistent tiredness that doesn’t improve with rest
- Shortness of breath: unexplained breathlessness during light activities or rest, which can be caused by fluid buildup in the lungs (because the heart isn’t circulating blood as well as it should)
- Chest discomfort: pain, pressure, tightness, or aching in the chest due to reduced blood flow to the heart muscle—often occurring during physical exertion or emotional stress
- Frequent indigestion: means that heartburn could be heart-related! This is about persistently reoccurring discomfort or pain in the upper abdomen
- Sleep disturbances: difficulties falling asleep, staying asleep, or waking up abruptly
- Excessive sweating: unexplained cold sweats or sudden sweating without physical exertion or excessive heat, can be a response to the decreased oxygen levels caused by less efficient blood flow
Note: this is a list of warning signs, not a diagnostic tool. Any or even all of these could be caused by something else. Just, don’t ignore the signs and do get yourself checked out.

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!

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!

Which Magnesium? (And: When?)
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.
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
❝Good morning! I have been waiting for this day to ask: the magnesium in my calcium supplement is neither of the two versions you mentioned in a recent email newsletter. Is this a good type of magnesium and is it efficiently bioavailable in this composition? I also take magnesium that says it is elemental (oxide, gluconate, and lactate). Are these absorbable and useful in these sources? I am not interested in taking things if they aren’t helping me or making me healthier. Thank you for your wonderful, informative newsletter. It’s so nice to get non-biased information❞
Thank you for the kind words! We certainly do our best.
For reference: the attached image showed a supplement containing “Magnesium (as Magnesium Oxide & AlgaeCal® l.superpositum)”
Also for reference: the two versions we compared head-to-head were these very good options:
Magnesium Glycinate vs Magnesium Citrate – Which is Healthier?
Let’s first borrow from the above, where we mentioned: magnesium oxide is probably the most widely-sold magnesium supplement because it’s cheapest to make. It also has woeful bioavailability, to the point that there seems to be negligible benefit to taking it. So we don’t recommend that.
As for magnesium gluconate and magnesium lactate:
- Magnesium lactate has very good bioavailability and in cases where people have problems with other types (e.g. gastrointestinal side effects), this will probably not trigger those.
- Magnesium gluconate has excellent bioavailability, probably coming second only to magnesium glycinate.
The “AlgaeCal® l.superpositum” supplement is a little opaque (and we did ntoice they didn’t specify what percentage of the magnesium is magnesium oxide, and what percentage is from the algae, meaning it could be a 99:1 ratio split, just so that they can claim it’s in there), but we can say Lithothamnion superpositum is indeed an algae and magnesium from green things is usually good.
Except…
It’s generally best not to take magnesium and calcium together (as that supplement contains). While they do work synergistically once absorbed, they compete for absorption first so it’s best to take them separately. Because of magnesium’s sleep-improving qualities, many people take calcium in the morning, and magnesium in the evening, for this reason.

Walnut, Apricot, & Sage Nut Roast
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.
It’s important to have at least one good nut roast recipe in your repertoire. It’s something that’s very good for making a good dish out of odds and ends that are in your house, and done well, it’s not only filling and nutritious, but a tasty treat too. Done badly, everyone knows the results can be unfortunate… Making this the perfect way to show off your skills!
You will need
- 1 cup walnuts
- ½ cup almonds
- ¼ cup whole mixed seeds (chia, pumpkin, & poppy are great)
- ¼ cup ground flax (also called flax meal)
- 1 medium onion, finely chopped
- 1 large carrot, grated
- 4 oz dried apricots, chopped
- 3 oz mushrooms, chopped
- 1 oz dried goji berries
- ½ bulb garlic, crushed
- 2 tbsp fresh sage, chopped
- 1 tbsp nutritional yeast
- 2 tsp dried rosemary
- 2 tsp dried thyme
- 2 tsp black pepper, coarse ground
- 1 tsp yeast extract (even if you don’t like it; trust us; it will work) dissolved in ¼ cup hot water
- ½ tsp MSG or 1 tsp low-sodium salt
- Extra virgin olive oil
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 350℉ / 180℃, and line a 2 lb loaf tin with baking paper.
2) Heat some oil in a skillet over a moderate heat, and fry the onion for a few minutes until translucent. Add the garlic, carrot, and mushrooms, cooking for another 5 minutes, stirring well. Set aside to cool a little once done.
3) Process the nuts in a food processor, pulsing until they are well-chopped but not so much that they turn into flour.
4) Combine the nuts, vegetables, and all the other ingredients in a big bowl, and mix thoroughly. If it doesn’t have enough structural integrity to be thick and sticky and somewhat standing up by itself if you shape it, add more ground flax. If it is too dry, add a little water but be sparing.
5) Spoon the mixture into the loaf tin, press down well (or else it will break upon removal), cover with foil and bake for 30 minutes. Remove the foil, and bake for a further 15 minutes, until firm and golden. When done, allow it to rest in the tin for a further 15 minutes, before turning it out.
6) Serve, as part of a roast dinner (roast potatoes, vegetables, gravy, etc).
Enjoy!

The Science Of New Year’s Pre-Resolutions
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 Science Of New Year’s Pre-Resolutions
There’s a military dictum that “prior preparation and planning prevents piss-poor performance”.
Would it surprise you to know that soldiers going on the attack are not focused on the goal? Rather, they are focused on the process.
With drills and mnemonics, everything that can be controlled for in advance is; every action, every reaction, everything that can go wrong, and all the “if x then y” decisions in between pre-battle PREWAR and PAWPERSO and post-battle PACESDO (all mnemonic acronyms; the content is not important here but the principle is).
In short: take Murphy’s Law into account now, and plan accordingly!
The same goes for making your plans the winning kind
If you want your resolutions to work, you may need to make pre-resolutions now, so that you’re properly prepared:
- Do you want to make an exercise habit? Make sure now that you have the right clothes/shoes/etc, make sure that they fit you correctly, make sure you have enough of them that you can exercise when one set’s in the wash, etc.
- What grace will you allow yourself if tired, unwell, busy? What’s your back-up plan so that you still do what you can at those times when “what you can” is legitimately a bit less?
- If it’s an outdoors plan, what’s your plan for when it’s rainy? Snowy? Dangerously hot?
- What are the parameters for what counts? Make it measurable. How many exercise sessions per week, what duration?
- Do you want to make a diet habit? Make sure that you have in the healthy foods that you want to eat; know where you can and will get things. We’re often creatures of habit when it comes to shopping, so planning will be critical here!
- Do you want to cut some food/drink/substance out? Make sure you have a plan to run down or otherwise dispose of your current stock first. And make sure you have alternatives set up, and if it was something you were leaning on as a coping strategy of some kind (e.g. alcohol, cannabis, comfort-eating, etc), make sure you have an alternative coping strategy, too!
See also: How To Reduce Or Quit Alcohol
We promised science, so here it comes
Approach-oriented resolutions work better than avoidance-oriented ones.
This means: positively-framed resolutions work better than negatively-framed ones.
On a simple level, this means that, for example, resolving to exercise three times per week is going to work better than resolving to not consume alcohol.
But what if you really want to quit something? Just frame it positively. There’s a reason that Alcoholics Anonymous (and similar Thing Anonymous groups) measure days sober, not relapses.
So it’s not “I will not consume alcohol” but “I will get through each day alcohol-free”.
Semantics? Maybe, but it’s also science:
Why January the 1st? It’s a fresh start
Resolutions started on the 1st of January enjoy a psychological boost of a feeling of a fresh start, a new page, a new chapter.
Similar benefits can be found from starting on the 1st of a month in general, or on a Monday, or on some date that is auspicious to the person in question (religious fasts tied to calendar dates are a fine example of this).
Again, this is borne-out by science:
The Fresh Start Effect: Temporal Landmarks Motivate Aspirational Behavior
Make it a habit
Here be science:
How do people adhere to goals when willpower is low? The profits (and pitfalls) of strong habits
As for how to do that?
How To Really Pick Up (And Keep!) Those Habits
Trim the middle
No, we’re not talking about your waistline. Rather, what Dr. Ayelet Fischbach refers to as “the middle problem”:
❝We’re highly motivated at the beginning. Over time, our motivation declines as we lose steam. To the extent that our goal has a clear end point, our motivation picks up again toward the end.
Therefore, people are more likely to adhere to their standards at the beginning and end of goal pursuit—and slack in the middle. We demonstrate this pattern of judgment and behavior in adherence to ethical standards (e.g., cheating), religious traditions (e.g., skipping religious rituals), and performance standards (e.g., “cutting corners” on a task).
We also show that the motivation to adhere to standards by using proper means is independent and follows a different pattern from the motivation to reach the end state of goal pursuit❞
Read: The end justifies the means, but only in the middle
How to fix this, then?
Give yourself consistent, recurring, short-term goals, with frequent review points. That way, it’s never “the middle” for long:

How Internal Organs Can Be Affected By Spicy Foods (Doctor Explains)
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.
Capsaicin has an array of health-giving properties in moderation, but consumed in immoderation and/or without building up tolerance first, can cause problems—serious health issues such as heart attacks, brain spasms, torn esophagus, and even death can occur.
Heating up
Capsaicin, the compound that gives peppers their “heat”, is a chemical irritant and neurotoxin that activates pain receptors (TRPV1) tricking the brain into sensing heat, leading to a burning sensation, sweating, and flushing. The pain signal can also trigger the fight-or-flight response, causing a surge of adrenaline. Endorphins are eventually released, creating a pain-relief effect similar to a runner’s high, and ultimately it reduces systemic inflammation, boosts the metabolism, and increases healthy longevity.
However, in cases of extreme consumption and/or lack of preparation, woe can befall, for example:
- A man ruptured his esophagus after vomiting from eating a ghost pepper.
- A participant experienced severe brain blood vessel constriction (reversible cerebral vasoconstriction syndrome) after eating a Carolina reaper.
- A 25-year-old suffered permanent heart damage from cayenne pepper pills due to restricted blood flow.
- A teenager died after the “one chip challenge,” although the cause of death was undetermined.
So, what does moderation and preparation look like?
Moderation can be different to different people, since genetics do play a part—some people have more TRPV1 receptors than other people. However, for all people (unless in case of having an allergy or similar), acclimatization is important, and a much bigger factor than genetics.
Writer’s anecdote: on the other hand, when my son was a toddler I once left the room and came back to find him cheerfully drinking hot sauce straight from the bottle, so it can be suspected that genetics are definitely relevant too, as while I did season his food and he did already enjoy curries and such, he didn’t exactly have a background of entering chili-eating competitions.
Still, regardless of genes (unless you actually have a medical condition that disallows this), a person who regularly eats spicy food will develop an increasing tolerance for spicy food, and will get to enjoy the benefits without the risks, provided they don’t suddenly jump way past their point of tolerance.
On which note, in this video you can also see what happens when Dr. Deshauer goes from biting a jalapeño (relatively low on the Scoville heat scale) to biting a Scotch bonnet pepper (about 10x higher on the Scoville heat scale):

We analysed almost 1,000 social media posts about 5 popular medical tests. Most were utterly misleading
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 Kim Kardashian posted on Instagram about having had a full-body MRI, she enthused that the test can be “life saving”, detecting diseases in the earliest stages before symptoms arise.
What Kardashian neglected to say was there’s no evidence this expensive scan can bring benefits for healthy people. She also didn’t mention it can carry harms including unnecessary diagnoses and inappropriate treatments.
With this post in mind, we wanted to explore what influencers are telling us about medical tests.
In a new study published today in JAMA Network Open, we analysed nearly 1,000 Instagram and TikTok posts about five popular medical tests which can all do more harm than good to healthy people, including the full-body MRI scan.
We found the overwhelming majority of these posts were utterly misleading.
C-R-V/Shutterstock 5 controversial tests
Before we get into the details of what we found, a bit about the five tests included in our study.
While these tests can be valuable to some, all five carry the risk of overdiagnosis for generally healthy people. Overdiagnosis is the diagnosis of a condition which would have never caused symptoms or problems. Overdiagnosis leads to overtreatment, which can cause unnecessary side effects and stress for the person, and wasted resources for the health system.
As an example, estimates suggest 29,000 cancers a year are overdiagnosed in Australia alone.
Overdiagnosis is a global problem, and it’s driven in part by healthy people having tests like these. Often, they’re promoted under the guise of early screening, as a way to “take control” of your health. But most healthy people simply don’t need them.
These are the five tests we looked at:
The full-body MRI scan claims to test for up to 500 conditions, including cancer. Yet there is no proven benefit of the scan for healthy people, and a real risk of unnecessary treatment from “false alarm” diagnoses.
The “egg timer” test (technically known as the AMH, or anti-mullarian hormone test) is often falsely promoted as a fertility test for healthy women. While it may be beneficial for women within a fertility clinic setting, it cannot reliably predict the chance of a woman conceiving, or menopause starting. However, low results can increase fear and anxiety, and lead to unnecessary and expensive fertility treatments.
Multi-cancer early detection blood tests are being heavily marketed as the “holy grail of cancer detection”, with claims they can screen for more than 50 cancers. In reality, clinical trials are still a long way from finished. There’s no good evidence yet that the benefits will outweigh the harms of unnecessary cancer diagnoses.
The gut microbiome test of your stool promises “wellness” via early detection of many conditions, from flatulence to depression, again without good evidence of benefit. There’s also concern that test results can lead to wasted resources.
Testosterone testing in healthy men is not supported by any high-quality evidence, with concerns direct-to-consumer advertising leads men to get tested and take testosterone replacement therapy unnecessarily. Use of testosterone replacement therapy carries its own risk of potential harms with the long-term safety in relation to heart disease and mortality still largely unknown.
Multi-cancer early detection blood tests are heavily marketed. Yuri A/Shutterstock What we found
Together with an international group of health researchers, we analysed 982 posts pertaining to the above tests from across Instagram and TikTok. The posts we looked at came from influencers and account holders with at least 1,000 followers, some with a few million followers. In total, the creators of the posts we included had close to 200 million followers.
Even discounting the bots, that’s a massive amount of influence (and likely doesn’t reflect their actual reach to non-followers too).
The vast majority of posts were misleading, failing to even mention the possibility of harm arising from taking one of these tests. We found:
- 87% of posts mentioned test benefits, while only 15% mentioned potential harms
- only 6% of posts mentioned the risk of overdiagnosis
- only 6% of posts discussed any scientific evidence, while 34% of posts used personal stories to promote the test
- 68% of influencers and account holders had financial interests in promoting the test (for example, a partnership, collaboration, sponsorship or selling for their own profit in some way).
Further analysis revealed medical doctors were slightly more balanced in their posts. They were more likely to mention the harms of the test, and less likely to have a strongly promotional tone.
The vast majority of posts we looked at were misleading. DimaBerlin/Shutterstock As all studies do, ours had some limitations. For example, we didn’t analyse comments connected to posts. These may give further insights into the information being provided about these tests, and how social media users perceive them.
Nonetheless, our findings add to the growing body of evidence showing misleading medical information is widespread on social media.
What can we do about it?
Experts have proposed a range of solutions including pre-bunking strategies, which means proactively educating the public about common misinformation techniques.
However, solutions like these often place responsibility on the individual. And with all the information on social media to navigate, that’s a big ask, even for people with adequate health literacy.
What’s urgently needed is stronger regulation to prevent misleading information being created and shared in the first place. This is especially important given social media platforms including Instagram are moving away from fact-checking.
In the meantime, remember that if information about medical tests promoted by influencers sounds too good to be true, it probably is.
