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
❝Loved the article on goji berries! I read they are good for blood sugars, is that true despite the sugar content?❞
Most berries are! Fruits that are high in polyphenols (even if they’re high in sugar), like berries, have a considerable net positive impact on glycemic health:

- Dietary polyphenols as antidiabetic agents: Advances and opportunities
And more specifically:

As for goji berries specifically, they’re very high indeed in polyphenols, and also have a hypoglycemic effect, i.e., they lower blood sugar levels (and as a bonus, increases HDL (“good” cholesterol) levels too, but that’s not the topic here):
❝The results of our study indicated a remarkable protective effect of LBP in patients with type 2 diabetes. Serum glucose was found to be significantly decreased and insulinogenic index increased during OMTT after 3 months administration of LBP. LBP also increased HDL levels in patients with type 2 diabetes. It showed more obvious hypoglycemic efficacy for those people who did not take any hypoglycemic medicine compared to patients taking hypoglycemic medicines. This study showed LBP to be a good potential treatment aided-agent for type 2 diabetes.❞
- LBP = Lycium barbarum polysaccharide, i.e. polysaccharide in/from goji berries
- OMTT = Oral metabolic tolerance test, a test of how well the blood sugars avoid spiking after a meal

Brazil Nuts vs Cashews – 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 Brazil nuts to cashews, we picked the cashews.
Why?
Looking at the macros first, Brazil nuts have more fat and fiber, while cashews have more carbs and protein. So, it really comes down to what you want to prioritize. We’d generally consider fiber the tie-breaker, making this category a subjective marginal win for Brazil nuts—and especially marginal since they are both low glycemic index foods in any case.
When it comes to vitamins, Brazil nuts have more of vitamins C, E, and choline, while cashews have more of vitamins B2, B3, B5, B6, B7, B9, and K, so while both are great, this category is a clear by-the-numbers win for cashews.
The category of minerals is an interesting one. Brazil nuts have more calcium, magnesium, phosphorus, and selenium, while cashews have more copper, iron, manganese, and zinc. That would be a 4:4 tie, but let’s take a closer look at those selenium levels:
- A cup of cashews contains 109% of the RDA of selenium. Your hair will be luscious and shiny.
- A cup of Brazil nuts contains 10,456% of the RDA of selenium. This is way past the point of selenium toxicity, and your (luscious, shiny) hair will fall out.
For this reason, it’s recommended to eat no more than 3–4 Brazil nuts per day.
We consider that a point against Brazil nuts.
Adding up the section makes for a win for cashews. Of course, enjoy Brazil nuts too if you will, but in careful moderation please!

How To Gain Weight (Healthily!)
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 Do You Have To Gain?
We have previously promised a three-part series about changing one’s weight:
- Losing weight (specifically, losing fat)
- Gaining weight (specifically, gaining muscle)
- Gaining weight (specifically, gaining fat)
There will be, however, no need for a “losing muscle” article, because (even though sometimes a person might have some reason to want to do this), it’s really just a case of “those things we said for gaining muscle? Don’t do those and the muscle will atrophy naturally”.
Here’s our first article: How To Lose Weight (Healthily!)
While some people will want to lose fat, please do be aware that the association between weight loss and good health is not nearly so strong as the weight loss industry would have you believe:
And, while BMI is not a useful measure of health in general, it’s worth noting that over the age of 65, a BMI of 27 (which is in the high end of “overweight”, without being obese) is associated with the lowest all-cause mortality:
BMI and all-cause mortality in older adults: a meta-analysis
Here was our second article: How To Build Muscle (Healthily!)
And now, it’s time for the last part, which yes, is also something that some people want/need to do (healthily!), and want/need help with that.
How to gain fat, healthily
Fat gets a bad press, but when it comes to health, we would die without it.
Even in the case of having excess fat, the fat itself is not generally the problem, so much as comorbid metabolic issues that are often caused by the same things as the excess fat.
So, how to gain fat healthily?
- Obvious but potentially dangerously misleading answer: “in moderation”
- More useful answer: “carefully”
Because, you can “in moderation” put on less than one pound per week for a few years and be in very bad health by the end of it. So how does this “carefully” work any differently to “in moderation”?
The key is in how we store the fat
Not merely where we store it (though that’ll follow from the “how”), but specifically: how we store it.
- When we consume energy from food in excess of our immediate survival needs, our body stores what it can. This is good!
- When our body is receiving energy from food faster than it can physically process it to store it healthily, it will start shoving it wherever it can instead. This is bad!
This is the physiological equivalent of the difference between tidying a room carefully, and cramming everything into one cupboard in 30 seconds just to get it out of sight.
So, you do need to consume calories yes, but you need to consume them in a way your body can take its time about storing them.
We’ve written before about the science of this, so we’ll share some links to that in a moment, but first, here are the practical tips:
- Do not drink your calories. Drinking calories tends to be the equivalent of injecting sugars directly into your veins, in terms of how quickly it gets received.
- See also: How To Unfatty A Fatty Liver ← this is highly relevant, because the same process that results in unhealthy weight gain, results in liver disease, by the same mechanism (the liver gets overwhelmed).
- Eat your greens. No, they won’t provide many calories, but they are critical to your body not being overwhelmed by the arrival of sugars.
- See also: 10 Ways To Balance Blood Sugars ← the other 9 things are also helpful for not putting on fat unhealthily, so using these alongside a calorie-dense diet can result in healthy fat gain as needed
- Get more of your calories from fats than carbs. Fats will not overwhelm your body’s glycemic response in the same way that carbs will.
- Again this is about getting calories while not getting metabolic disease. See also: How To Prevent And Reverse Type Two Diabetes as the advice is the same for that, for the same reason!
- Consider going low-carb, but even if you choose not to, go for carbs with a low glycemic index instead of a high glycemic index.
- For reference, see: Glycemic Index Chart: Glycemic index and glycemic load ratings for 500+ foods
- Need healthy fats in a snack? Enjoy nuts (unless you have an allergy); they will be your best friend in this regard. As an example, a mere 1oz portion of cashew nuts has 157 calories.
- See also: Why You Should Diversify Your Nuts
- Need health fats for cooking? Enjoy olive oil, as it has one of the healthiest lipids profiles available, and is a great way to increase the calorific content of many meals.
Lastly…
Be patient, enjoy your food, and stick as best you can to the above considerations. All strength to you.
Take care!

Avoiding Razor Burn, Ingrown Hairs & Other Shaving Irritation
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.
How Does The Video Help?
Dr. Simi Adedeji’s incredibly friendly persona makes this video (below) on avoiding skin irritation, ingrown hairs, and razor burn after shaving a pleasure to watch.
To keep things simple, she breaks down her guide into 10 simple tips.
What Are The 10 Simple Tips?
Tip 1: Prioritize Hydration. Shaving dry hair can lead to increased skin irritation, so Dr. Simi recommends moistening the hair by showering or using a warm, wet towel for 2-4 minutes before getting the razor out.
Tip 2: Avoid Dry Shaving. Dry shaving not only removes hair but can also remove the protective upper layer of skin, which contributes to razor burn. To prevent this, simply use some shaving gel or cream.
Tip 3: Keep Blades New and Sharp. This one’s simple: dull blades can cause skin irritation, whilst a sharp blade ensures a smoother and more comfortable shaving experience.
Tip 4: Avoid Shaving the Same Area Repeatedly. Multiple passes over the same area can remove skin layers, leading to cuts and irritation. Aim to shave each area only once for safer results.
Tip 5: Consider Hair Growth Direction. Shaving in the direction of hair growth results in less irritation, although it may not provide the closest shave.
Tip 6: Apply Gentle Pressure While Shaving. Excessive pressure can lead to cuts and nicks. Use a gentle touch to reduce these risks.
Tip 7: Incorporate Exfoliation into Your Routine. Exfoliating helps release trapped hairs and reduces the risk of ingrown hairs. For those with sensitive skin, it’s recommended to exfoliate either two days before or after shaving.
Tip 8: Avoid Excessive Skin Stretching. Over-stretching the skin during shaving can cause hairs to become ingrown.
Tip 9: Moisturize After Shaving. Shaving can compromise the skin barrier, leading to dryness. Using a moisturizer can be a simple fix.
Tip 10: Regularly Rinse Your Blade. Make sure that, during the shaving process, you are rinsing your blade frequently to remove hair and skin debris. This keeps it sharp during your shave.
If this summary doesn’t do it for you, then you can watch the full video here:

How To Grow New Brain Cells (At Any Age)
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.
How To Grow New Brain Cells (At Any Age)
It was long believed that brain growth could not occur later in life, due to expending our innate stock of pluripotent stem cells. However, this was mostly based on rodent studies.
Rodent studies are often used for brain research, because it’s difficult to find human volunteers willing to have their brains sliced thinly (so that the cells can be viewed under a microscope) at the end of the study.
However, neurobiologist Dr. Maura Boldrini led a team that did a lot of research by means of autopsies on the hippocampi of (previously) healthy individuals ranging in age from 14 to 79.
What she found is that while indeed the younger subjects did predictably have more young brain cells (neural progenitors and immature neurons), even the oldest subject, at the age of 79, had been producing new brain cells up until death.
Read her landmark study: Human Hippocampal Neurogenesis Persists throughout Aging
There was briefly a flurry of news articles about a study by Dr. Shawn Sorrels that refuted this, however, it later came to light that Dr. Sorrels had accidentally destroyed his own evidence during the cell-fixing process—these things happen; it’s just unfortunate the mistake was not picked up until after publication.
A later study by a Dr. Elena Moreno-Jiménez fixed this flaw by using a shorter fixation time for the cell samples they wanted to look at, and found that there were tens of thousands of newly-made brain cells in samples from adults ranging from 43 to 87.
Now, there was still a difference: the samples from the youngest adult had 30% more newly-made braincells than the 87-year-old, but given that previous science thought brain cell generation stopped in childhood, the fact that an 87-year-old was generating new brain cells 30% less quickly than a 43-year-old is hardly much of a criticism!
As an aside: samples from patients with Alzheimer’s also had a 30% reduction in new braincell generation, compared to samples from patients of the same age without Alzheimer’s. But again… Even patients with Alzheimer’s were still growing some new brain cells.
Read it for yourself: Adult hippocampal neurogenesis is abundant in neurologically healthy subjects and drops sharply in patients with Alzheimer’s disease
Practical advice based on this information
Since we can do neurogenesis at any age, but the rate does drop with age (and drops sharply in the case of Alzheimer’s disease), we need to:
Feed your brain. The brain is the most calorie-consuming organ we have, by far, and it’s also made mostly of fat* and water. So, get plenty of healthy fats, and get plenty of water.
*Fun fact: while depictions in fiction (and/or chemically preserved brains) may lead many to believe the brain has a rubbery consistency, the untreated brain being made of mostly fat and water gives it more of a blancmange-like consistency in reality. That thing is delicate and spatters easily. There’s a reason it’s kept cushioned inside the strongest structure of our body, far more protected than anything in our torso.
Exercise. Specifically, exercise that gets your blood pumping. This (as our earlier-featured video today referenced) is one of the biggest things we can do to boost Brain-Derived Neurotrophic Factor, or BDNF.
Here be science: Brain-Derived Neurotrophic Factor, Depression, and Physical Activity: Making the Neuroplastic Connection
However, that’s not the only way to increase BDNF; another is to enjoy a diet rich in polyphenols. These can be found in, for example, berries, tea, coffee, and chocolate. Technically those last two are also botanically berries, but given how we usually consume them, and given how rich they are in polyphenols, they merit a special mention.
See for example: Effects of nutritional interventions on BDNF concentrations in humans: a systematic review
Some supplements can help neuron (re)growth too, so if you haven’t already, you might want to check out our previous main feature on lion’s mane mushroom, a supplement which does exactly that.

No, taking drugs like Ozempic isn’t ‘cheating’ at weight loss or the ‘easy way out’
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.
Hundreds of thousands of people worldwide are taking drugs like Ozempic to lose weight. But what do we actually know about them? This month, The Conversation’s experts explore their rise, impact and potential consequences.
Obesity medication that is effective has been a long time coming. Enter semaglutide (sold as Ozempic and Wegovy), which is helping people improve weight-related health, including lowering the risk of a having a heart attack or stroke, while also silencing “food noise”.
As demand for semaglutide increases, so are claims that taking it is “cheating” at weight loss or the “easy way out”.
We don’t tell people who need statin medication to treat high cholesterol or drugs to manage high blood pressure they’re cheating or taking the easy way out.
Nor should we shame people taking semaglutide. It’s a drug used to treat diabetes and obesity which needs to be taken long term and comes with risks and side effects, as well as benefits. When prescribed for obesity, it’s given alongside advice about diet and exercise.
How does it work?
Semaglutide is a glucagon-like peptide-1 receptor agonist (GLP-1RA). This means it makes your body’s own glucagon-like peptide-1 hormone, called GLP-1 for short, work better.
GLP-1 gets secreted by cells in your gut when it detects increased nutrient levels after eating. This stimulates insulin production, which lowers blood sugars.
GLP-1 also slows gastric emptying, which makes you feel full, and reduces hunger and feelings of reward after eating.
GLP-1 receptor agonist (GLP-1RA) medications like Ozempic help the body’s own GLP-1 work better by mimicking and extending its action.
Some studies have found less GLP-1 gets released after meals in adults with obesity or type 2 diabetes mellitus compared to adults with normal glucose tolerance. So having less GLP-1 circulating in your blood means you don’t feel as full after eating and get hungry again sooner compared to people who produce more.
GLP-1 has a very short half-life of about two minutes. So GLP-1RA medications were designed to have a very long half-life of about seven days. That’s why semaglutide is given as a weekly injection.
What can users expect? What does the research say?
Higher doses of semaglutide are prescribed to treat obesity compared to type 2 diabetes management (up to 2.4mg versus 2.0mg weekly).
A large group of randomised controlled trials, called STEP trials, all tested weekly 2.4mg semaglutide injections versus different interventions or placebo drugs.
Trials lasting 1.3–2 years consistently found weekly 2.4 mg semaglutide injections led to 6–12% greater weight loss compared to placebo or alternative interventions. The average weight change depended on how long medication treatment lasted and length of follow-up.
Higher doses of semaglutide are prescribed for obesity than for type 2 diabetes. fcm82/Shutterstock Weight reduction due to semaglutide also leads to a reduction in systolic and diastolic blood pressure of about 4.8 mmHg and 2.5 mmHg respectively, a reduction in triglyceride levels (a type of blood fat) and improved physical function.
Another recent trial in adults with pre-existing heart disease and obesity, but without type 2 diabetes, found adults receiving weekly 2.4mg semaglutide injections had a 20% lower risk of specific cardiovascular events, including having a non-fatal heart attack, a stroke or dying from cardiovascular disease, after three years follow-up.
Who is eligible for semaglutide?
Australia’s regulator, the Therapeutic Goods Administration (TGA), has approved semaglutide, sold as Ozempic, for treating type 2 diabetes.
However, due to shortages, the TGA had advised doctors not to start new Ozempic prescriptions for “off-label use” such as obesity treatment and the Pharmaceutical Benefits Scheme doesn’t currently subsidise off-label use.
The TGA has approved Wegovy to treat obesity but it’s not currently available in Australia.
When it’s available, doctors will be able to prescribe semaglutide to treat obesity in conjunction with lifestyle interventions (including diet, physical activity and psychological support) in adults with obesity (a BMI of 30 or above) or those with a BMI of 27 or above who also have weight-related medical complications.
What else do you need to do during Ozempic treatment?
Checking details of the STEP trial intervention components, it’s clear participants invested a lot of time and effort. In addition to taking medication, people had brief lifestyle counselling sessions with dietitians or other health professionals every four weeks as a minimum in most trials.
Support sessions were designed to help people stick with consuming 2,000 kilojoules (500 calories) less daily compared to their energy needs, and performing 150 minutes of moderate-to-vigorous physical activity, like brisk walking, dancing and gardening each week.
STEP trials varied in other components, with follow-up time periods varying from 68 to 104 weeks. The aim of these trials was to show the effect of adding the medication on top of other lifestyle counselling.
Trial participants also exercised for 150 minutes a week. Elena Nichizhenova/Shutterstock A review of obesity medication trials found people reported they needed less cognitive behaviour training to help them stick with the reduced energy intake. This is one aspect where drug treatment may make adherence a little easier. Not feeling as hungry and having environmental food cues “switched off” may mean less support is required for goal-setting, self-monitoring food intake and avoiding things that trigger eating.
But what are the side effects?
Semaglutide’s side-effects include nausea, diarrhoea, vomiting, constipation, indigestion and abdominal pain.
In one study these led to discontinuation of medication in 6% of people, but interestingly also in 3% of people taking placebos.
More severe side-effects included gallbladder disease, acute pancreatitis, hypoglycaemia, acute kidney disease and injection site reactions.
To reduce risk or severity of side-effects, medication doses are increased very slowly over months. Once the full dose and response are achieved, research indicates you need to take it long term.
Given this long-term commitment, and associated high out-of-pocket cost of medication, when it comes to taking semaglutide to treat obesity, there is no way it can be considered “cheating”.

Curing Hiccups And Headaches At Home With Actual Science
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.
Quick fixes for bodily annoyances
Do you ever find yourself desperately trying to cure hiccups, and advice on the Internet is like “breathe in through your ears while drinking vinegar upside-down through your nose”?
If so, you’re not alone. So, today we’re going to look at some science-based approaches to dealing with common bodily annoyances.
Hiccups
Unfortunately, most popular advices simply don’t work, and the only near-guaranteed way to cure these is with anti-convulsive medications whose side-effects may be worse than the hiccups.
However, before you head to the pharmacy, there is one breathing exercise that has a very simple scientific underpinning: 4:4 breathing. If you’re unfamiliar, it’s just:
- Breathe slowly in through your nose to a count of four
- Hold your breath for a count of four
- Breathe slowly out through your nose to a count of four
- Hold your breath for a count of four
…and repeat. The slower the better. At first, your hiccups will interrupt this, but just “keep calm and carry on”.
The reason this can work is that breathing is an autonomic function (e.g., it happens without us thinking about it) that, unlike most other autonomic functions, we can all control directly. By taking control of one, others will tend to fall into line with it.
For example, it is normal that your heart rate will tend to slow or quicken as your breathing slows or quickens, respectively.
Your hiccups? Autonomic function. Actually a very, very old evolutionary left-over trait, that’s only useful for protecting lungs while breathing underwater. In other words, it’s the bodily function thinks you’re a fish (or a tadpole-like amphibious creature) in the process of developing lungs. Unfortunately, because hiccuping doesn’t harm our chances of passing on our genes, it never got naturally de-selected so we still have it.
Anyway, the bottom line is: take control of your breathing in the aspects you can directly control, and the aspects you can’t directly control will fall into line. You may need to give it some minutes, don’t give up too quickly.
Headaches
If you ever get a headache and you don’t have painkillers or perhaps they’re not helping or you have another reason for not wanting to take them, there’s “one quick trick” that can cure most headaches in seconds.
First, the limitation: this will only cure headaches that have been caused by increased localized blood pressure in the forehead. However, that’s more than half of most common headaches.
Next, how it works…
We’re mentioning this first, because understanding how it works will give you more confidence in using it.
Your body has a wonderful homeostatic system, which is the system by which your body maintains its “Goldilocks zones” of not too hot or cold, not to acidine or alkaline, not too hydrated or dehydrated, blood pressure not too high or too low, etc. Sometimes, however, it can get confused, and needs a nudge back to where it should be.
One of the ways it maintains blood pressure is biofeedback from receptors in blood vessel walls, called baroreceptors. They are what it sounds like; they measure blood pressure internally.
In certain places, there are clusters of baroreceptors in one place. And if we press on that one place, the body will think “Oh no! Super high blood pressure in this bit!” and reduce the blood pressure immediately.
This is called the baroreflex, and that’s what you need to cure a hypertensive headache.
So, what to do:
With your thumb, carefully feel the upper inside corner of your eye socket. So, at the top, and about ¼ of the way out from the bridge of your nose. You should feel a groove. No, not like the Emperor’s New, but, an actual groove in your eye socket. That’s the supraorbital notch (or foramen), and it allows the supraorbital artery, veins, and nerve to run through.
Press it firmly (you can do both sides at once, assuming you have two thumbs) for about three seconds, and then massage it gently. Repeat as necessary, but it shouldn’t take more than about three goes to have cured the headache.
As a bonus, this is a great party trick for curing other people’s headaches, when the need arises!
