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 😎
❝Hi, is there any important difference between vitamin d2 and vitamin d3? Is one better than the other?❞
There is indeed! And one is better than the other!
Where they come from
You’ll find a lot of sources that will tell you “Vitamin D2 is from plants, D3 is from animals”, and in fact only the second half of that is true.
In nature, there are no plants that are known to produce vitamin D.
Vitamin D2, however, is produced by many fungi, as well as algae, neither of which are part of the Kingdom Plantae.
Vitamin D3, meanwhile, is produced by many animals (including humans).
When “the sun” is sometimes considered a source of vitamin D, that’s true only insofar as the sun is also a source of tomatoes, for example, which required the sun to grow. While we humans (and other animals) cannot photosynthesize in general, producing vitamin D is something we can do if exposed to UV light (such as from the sun).
However, of course exposure to UV light (such as from the sun) comes with other problems, so… Should we get sun exposure or not?
We weighed up the balance of evidence, here: The Sun Exposure Dilemma
If, like this writer, you are a mostly crepuscular being who avoids the sun, we have good news: mushrooms can do the sunbathing for us!
❝Exposing mushrooms to UV (from sunlight or in a laboratory) increases the amount of vitamin D in mushrooms by nearly eightfold. Putting five store-bought button mushrooms in the sun, or just one portobello mushroom, produces 24 µg of vitamin D, which translates to nearly 1000 international units, providing the amount of vitamin D one needs in an entire day, and the equivalent found in most vitamin D supplements.
If you’re wondering if the vitamin D from mushrooms actually makes it into your bloodstream, it does. A recent meta-analysis of randomized controlled trials showed that tanned (UV-exposed) mushrooms may be effective in increasing active vitamin D levels in adults with low levels of vitamin D, and studies (randomised controlled trials) have shown that it may be just as effective as supplements at increasing vitamin D levels in the blood (here, and here).
Some research is very positive, saying that putting your mushrooms in direct sunlight for 10–15 minutes may provide you with 100% of your daily vitamin D needs, and the vitamin D content in sunlight-exposed mushrooms may be retained with refrigeration for up to 8 days.
The production of vitamin D may be increased by a further 30% by placing them in the sun with the underside, or gills, facing up, or by 60% if you slice them.❞
Read all about it: Tan your mushrooms, not your skin
Which is better?
In few words: D3 is better.
They both do the exact same job, but with D3, you simply get more bang-for-buck:
❝The WMD in change in total 25(OH)D based on 12 daily dosed vitamin D2-vitamin D3 comparisons, analyzed using liquid chromatography-tandem mass spectrometry, was 10.39 nmol/L (40%) lower for the vitamin D2 group compared with the vitamin D3 group.
Vitamin D3 leads to a greater increase of 25(OH)D than vitamin D2, even if limited to daily dose studies, but vitamin D2 and vitamin D3 had similar positive impacts on their corresponding 25(OH)D hydroxylated forms.❞
Note: “WMD” here means “weighted mean difference”, not “weapons of mass destruction”
About that “and importance of BMI”, by the way: in persons with a BMI >25, there was no longer a difference between the two forms. Literally, no difference at all; the difference was reduced to 0%.
Another study found similarly, but with different numbers (finding a greater difference), and without recording BMI as a factor:
❝D3 is approximately 87% more potent in raising and maintaining serum 25(OH)D concentrations and produces 2- to 3-fold greater storage of vitamin D than does equimolar D2.❞
See the paper: Vitamin D3 Is More Potent Than Vitamin D2 in Humans
“Well that sucks, because I’m vegan”
Fear not, you can get vegan D3 too.
Much like “you can’t get vegan B12” (but you can; it’s made by yeast), there are vegan D3 supplements, made by lichen.
The trouble with lichen, when it comes to classifying it, it that it’s actually a hybrid colony of many small, strange things (beyond the scope of this article, but they are fascinating, so this writer is holding herself back by the scruff of the neck from explaining in detail), some of which are technically part of Kingdom Animalia, but it is hard to find even the most ardent vegan who will object to consuming bacteria, for example.
Want to try some?
We don’t sell it, but here for your convenience is an example product on Amazon 😎
But watch out with the doses, if supplementing vitamin D in either form, because…

Blue Light At Night? Save More Than Just Your Sleep!
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.
Beating The Insomnia Blues
You previously asked us about recipes for insomnia (or rather, recipes/foods to help with easing insomnia). We delivered!
But we also semi-promised we’d cover a bit more of the general management of insomnia, because while diet’s important, it’s not everything.
Sleep Hygiene
Alright, you probably know this first bit, but we’d be remiss if we didn’t cover it before moving on:
- No caffeine or alcohol before bed
- Ideally: none earlier either, but if you enjoy one or the other or both, we realize an article about sleep hygiene isn’t going to be what changes your mind
- Fresh bedding
- At the very least, fresh pillowcase(s). While washing and drying an entire bedding set constantly may be arduous and wasteful of resources, it never hurts to throw your latest pillowcase(s) in with each load of laundry you happen to do.
- Warm bed, cool room = maximum coziness
- Dark room. Speaking of which…
About That Darkness…
When we say the room should be dark, we really mean it:
- Not dark like “evening mood lighting”, but actually dark.
- Not dark like “in the pale moonlight”, but actually dark.
- Not dark like “apart from the light peeking under the doorway”, but actually dark.
- Not dark like “apart from a few LEDs on electronic devices that are on standby or are charging”, but actually dark.
There are many studies about the impact of blue light on sleep, but here’s one as an example.
If blue light with wavelength between 415 nm and 455 nm (in the visible spectrum) hits the retina, melatonin (the sleep hormone) will be suppressed.
The extent of the suppression is proportional to the amount of blue light. This means that there is a difference between starting at an “artificial daylight” lamp, and having the blue LED of your phone charger showing… but the effect is cumulative.
And it gets worse:
❝This high energy blue light passes through the cornea and lens to the retina causing diseases such as dry eye, cataract, age-related macular degeneration, even stimulating the brain, inhibiting melatonin secretion, and enhancing adrenocortical hormone production, which will destroy the hormonal balance and directly affect sleep quality.❞
Read it in full: Research progress about the effect and prevention of blue light on eyes
See also: Age-related maculopathy and the impact of blue light hazard
So, what this means, if we value our health, is:
- Switch off, or if that’s impractical, cover the lights of electronic devices. This might be as simple as placing your phone face-down rather than face-up, for instance.
- Invest in blackout blinds/curtains (per your preference). Serious ones, like these ← see how they don’t have to be black to be blackout! You don’t have to sacrifice style for function
- If you can’t reasonably do the above, consider a sleep mask. Again, a good one. Not the kind you were given on a flight, or got free with some fluffy handcuffs. We mean a full-blackout sleep mask that’s designed to be comfortable enough to sleep in, like this one.
- If you need to get up to pee or whatever, do like a pirate and keep one eye covered/closed. That way, it’ll remain unaffected by the light. Pirates did it to retain their night vision when switching between being on-deck or below, but you can do it to halve the loss of melatonin.
Lights-Out For Your Brain Too
You can have all the darkness in the world and still not sleep if your mind is racing thinking about:
- your recent day
- your next day
- that conversation you wish had gone differently
- what you really should have done when you were 18
- how you would go about fixing your country’s socio-political and economic woes if you were in charge
- Etc.
We wrote about how to hit pause on all that, in a previous edition of 10almonds.
Check it out: The Off-Button For Your Brain—How to “just say no” to your racing mind (this trick really works)
Sweet dreams!

The Coffee-Cortisol Connection, And Two Ways To Tweak It For Health
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.
Health opinions on coffee vary from “it’s an invigorating, healthful drink” to “it will leave you a shaking frazzled wreck”. So, what’s the truth and can we enjoy it healthily? Dr. Alan Mandell weighs in:
Enjoy it, but watch out!
Dr. Mandell is speaking only for caffeinated coffee in this video, and to this end, he’s conflating the health effects of coffee and caffeine. A statistically reasonable imprecision, since most people drink coffee with its natural caffeine in, but we’ll make some adjustment to his comments below, to disambiguate which statements are true for coffee generally, and which are true for caffeine:
- Drinking
coffeecaffeine first thing in the morning may not be ideal due to dehydration from overnight water loss. Coffeecaffeine is a diuretic, which means an increase in urination, thus further dehydrating the body.- Coffee contains great antioxidants, which are of course beneficial for the health in general.
- Cortisol, the body’s stress hormone, is generally at its peak in the morning. This is, in and of itself, good and correct—it’s how we wake up.
Coffeecaffeine consumption raises cortisol levels even more, leading to increased alertness and physical readiness, but it is possible to have too much of a good thing, and in this case, problems can arise because…- Elevated cortisol from early
coffeecaffeine drinking can build tolerance, leading to the need for morecoffeecaffeine over time. - It’s better, therefore, to defer drinking
coffeecaffeine until later in the morning when cortisol levels naturally drop. - All of this means that drinking
coffeecaffeine first thing can disrupt the neuroendocrine system, leading to fatigue, depression, and general woe. - Hydrate first thing in the morning before consuming
coffeecaffeine to keep the body balanced and healthy.
What you can see from this is that coffee and caffeine are not, in fact, interchangeable words, but the basic message is clear and correct: while a little spike of cortisol in the morning is good, natural, and even necessary, a big spike is none of those things, and caffeine can cause a big spike, and since for most people caffeine is easy to build tolerance to, there will indeed consistently be a need for more, worsening the problem.
In terms of hydration, it’s good to have water (or better yet, herbal tea) on one’s nightstand to drink when one wakes up.
If coffee is an important morning ritual for you, consider finding a good decaffeinated version for at least your first cup (this writer is partial to Lavazza’s “Dek Intenso”—which is not the same as their main decaf line, by the way, so do hold out for the “Dek Intenso” if you want to try my recommendation).
Decaffeinated coffee is hydrating and will not cause a cortisol spike (unless for some reason you find coffee as a concept very stressful in which case, yes, the stressor will cause a stress response).

Astrology, Mental health and the Economics of Well Being
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.
Ultimately can the mental health system single-handedly address the concerns of inequality and economic access in society?
Around 75 per cent of the Indian population lives in rural areas, but their access to quality mental health care is limited and traditional approaches continue to be in use. The shortage is to such a large extent that there are only 0.7 physicians per 1000 population and only one psychiatrist for every 343,000 Indians. While over the years the mental health sector has seen major developments, like the 2017 mental health care act. This act establishes equal access for all citizens, to avail government-run or funded mental health services in the country. However, it does not bridge the gap in society as the majority of the population remains deeply unaware or unable to access these services.
While the uncertainties of the pandemic brought mental wellbeing to the forefront, the national budget for the sector dropped, making this an issue of human rights. This accessibility to services is further corroborated by the recurring financial expenses of medications and frequent visits to government clinics. The cost of sessions is steep and a single session is not ideal. Spending exorbitant amounts on healthcare is a burden most families can’t afford leading to debt. In the absence of insurance and healthcare schemes and provisions, therapy remains a luxury to many Indians.
Economic struggles are only one of the causes of this discerning gap in the mental health sector. Barriers caused by sexuality, gender, caste and religion also play a major role in mediating people’s perception and access to therapeutic services. The persistent stigma surrounding mental health, especially in India continues to be a hindrance to seeking help. The supernatural inhibitions and disparity in knowledge across communities only create more confusion. The notion that mental well being is an optional expense is popular, even though the country’s population is in a dire state. Data collected in a WHO report found that nearly 15 per cent of Indian adults need active intervention for one or more mental health issues.
The population disregards the very prevalence of such mental disorders and more than often finds it fruitless to receive treatment. Some who are open-minded fail to afford the hiked fees that therapists in urban settings charge, leaving them with no option. While for years Indians attributed the systemic weakness of the mental health system to the people’s attitudes, a 2016 survey showed more than 42% of people have positive attitudes toward mental wellbeing and treatment. While the skeptics remain, these underprivileged sections of society too struggle to gain the accessibility they deserve.
This is where astrology, tarot card reading and other spiritual practices, have created a market for themselves in the well-being industry. The sceptics, and those from poor socio-economic backgrounds resort to these local and easily accessible ways of coping, to instil the faith they so desperately need. Astrology is a layman’s substitute for therapy, or for some even a supplement when they cannot afford extended periods of treatment. Visiting a local astrologer in many ways breeds the self-awareness one would expect from a session in therapy. These practices even hold certain similarities to actual psychotherapy settings, in the way they define, and alleviate aspects of one’s personality and behaviour.
Very often one simply needs an explanation, or an answer to the ‘why’ no matter how scientifically rooted that response truly is. Astrologers impart a level of faith, that things will get better. For those in rural areas, struggling to provide the bare necessities to their family affording therapy is impossible, so their local psychic, astrologer or pandit becomes their anchor during emotional duress. Tarot cards and other practices primarily focus on the future and act as a guide point for how to deal with the things ahead. For a farmer coping with anxiety, access to anti-anxiety medication is strained, and so is therapy. His best bet remains to consult his next-door jyotish about his burdens.
A famous clinician Caroline Hexdall in an interview said that “ Part of the popularity of astrology and tarot today has to do with their universal nature”. With growing technology and the pervasiveness of social media, people can gain easy access to self-care and astrology resources. Apps and web pages provide daily tarot cards, zodiac signs readings and astrological predictions for people, and almost serve the purpose of a therapist. Is reading the lines on our palm, and checking the alignment of the stars enough to cure the mental illness they undergo? Is it a solution or a quick fix as a consequence of an ignorant healthcare system?
Several studies have also shown the deteriorating effects of depending on astrology. Cases of worsening and onset of depression, anxiety and personality disorders are common for those who use astrology as more than just a temporary coping mechanism. It also becomes a source of losing control, as every feeling is attributed to fate and destiny, instilling a sense of helplessness. Ultimately can the mental health system single-handedly address the concerns of inequality and economic access in society?

Sarah Raven’s Garden Cookbook – by Sarah Raven
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.
Note: the US Amazon site currently (incorrectly) lists the author as “Jonathan Buckley”. The Canadian, British, and Australian sites all list the author correctly as Sarah Raven, and some (correctly) credit Jonathan Buckley as the photographer she used.
First, what it’s not: a gardening book. Beyond a few helpful tips, pointers, and “plant here, harvest here” instructions, this book assumes you are already capable of growing your own vegetables.
She does assume you are in a temperate climate, so if you are not, this might not be the book for you. Although! The recipes are still great; it’s just you’d have to shop for the ingredients and they probably won’t be fresh local produce for the exact same reason that you didn’t grow them.
If you are in a temperate climate though, this will take you through the year of seasonal produce (if you’re in a temperate climate but it’s in for example Australia, you’ll need to make a six-month adjustment for being in the S. Hemisphere), with many recipes to use not just one ingredient from your garden at a time, but a whole assortment, consistent with the season.
About the recipes: they (which are 450 in number) are (as you might imagine) very plant-forward, but they’re generally not vegan and often not vegetarian. So, don’t expect that you’ll produce everything yourself—just most of the ingredients!
Bottom line: if you like cooking, and are excited by the idea of growing your own food but are unsure how regularly you can integrate that, this book will keep you happily busy for a very long time.
Click here to check out Sarah Raven’s Garden Cookbook, and level-up your home cooking!

A Supplement To Rival St. John’s Wort Against Depression
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.
Do You Feel The SAMe?
S-Adeonsyl-L-Methionone (SAMe) is a chemical found naturally in the body, and/but enjoyed widely as a supplement. The main reasons people take it are:
- Improve mood (antidepressant effect)
- Improve joints (reduce osteoarthritis symptoms)
- Improve liver (detoxifying effect)
Let’s see what the science says for each of those claims…
Does it improve mood?
It seems to perform comparably to St. John’s Wort (which is good; it performs comparably to Prozac).
Best of all, it does this with fewer contraindications (St. John’s Wort has so many contraindications).
Here’s how they stack up:
This looks very promising, though it’d be nice to see a larger body of research, to be sure.
Does it reduce osteoarthritis symptoms?
The good news: it performs comparably to ibuprofen, with fewer side effects!
The bad news: it also performs comparably to placebo!
Read into that what you will about ibuprofen’s usefulness vs OA symptoms.
Read all about it:
S-Adenosylmethionine for osteoarthritis of the knee or hip
If you were hoping for something for OA or similar symptoms, you might like our previous main features:

- Managing Chronic Pain (Realistically!)
- The 7 Approaches To Pain Management
- (Science-Based) Alternative Pain Relief
Does it help against liver disease?
According to adverts for SAMe: absolutely!
According to science: we don’t know
The science for this is so weak that it’d be unworthy of mention if it weren’t for the fact that SAMe is so widely sold as good against hepatotoxicity.
To be clear: maybe it really is great! Science hasn’t yet disproved its usefulness either.
It is popularly assumed to be beneficial due to there being an association between lower levels of SAMe in the body (remember, it is also produced inside our bodies) and development of liver disease, especially cholestasis.
Here’s an example of what pretty much every study we found was like (inconclusive research based mostly on mice):
S-adenosylmethionine in liver health, injury, and cancer
For other options for liver health, consider:
Is it safe?
Safety trials have been done ranging from 3 months to 2 years, with no serious side effects coming to light. So, it appears quite safe.
That said, as with anything, there are contraindications, such as:
- if you have bipolar disorder, skip this unless directed by your health care provider, because it may worsen the symptoms of mania
- if you are on SSRIs or other serotonergic drugs, it may interact with those
- if you are immunocompromised, you might want to skip it can increase the risk of P. carinii growth in such cases
As always, do speak with your doctor/pharmacist for personalized advice.
Summary
SAMe’s evidence-based qualities seem to stack up as follows:
- Against depression: good
- Against osteoarthritis: weak
- Against liver disease: unknown
As for safety, it has been found quite safe for most people.

Mouthwatering Protein Falafel
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.
Baking falafel, rather than frying it, has a strength and a weakness. The strength: it is less effort and you can do more at once. The weakness: it can easily get dry. This recipe calls for baking them in a way that won’t get dry, and the secret is one of its protein ingredients: peas! Add to this the spices and a tahini sauce, and you’ve a mouthwatering feast that’s full of protein, fiber, polyphenols, and even healthy fats.
You will need
- 1 cup peas, cooked
- 1 can chickpeas, drained and rinsed (keep the chickpea water—also called aquafaba—aside, as we’ll be using some of it later)
- ½ small red onion, chopped
- 1 handful fresh mint, chopped
- 1 tbsp fresh parsley, chopped
- ½ bulb garlic, crushed
- 1 tbsp lemon juice
- 1 tbsp chickpea flour (also called gram flour, besan flour, or garbanzo bean flour) plus more for dusting
- 2 tsp red chili flakes (adjust per heat preferences)
- 2 tsp black pepper, coarse ground
- 1 tsp ground turmeric
- ½ tsp MSG or 1 tsp low-sodium salt
- Extra virgin olive oil
For the tahini sauce:
- 2 tbsp tahini
- 2 tbsp lemon juice
- ¼ bulb garlic, crushed
- 5 tbsp aquafaba (if for some reason you don’t have it, such as for example you substituted 1 cup chickpeas that you cooked yourself, substitute with water here)
To serve:
- Flatbreads (you can use our Healthy Homemade Flatbreads recipe if you like)
- Leafy salad
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 350℉ / 180℃.
2) Blend the peas and chickpeas in a food processor for a few seconds. You want a coarse mixture, not a paste.
3) Add the rest of the main section ingredients except the olive oil, and blend again for a few more seconds. It should still have a chunky texture, or else you will have made hummus. If you accidentally make hummus, set your hummus aside and start again on the falafels.
4) Shape the mixture into balls; if it lacks structural integrity, fold in a little more chickpea flour until the balls stay in shape. Either way, once you have done that, dust the balls in chickpea flour.
5) Brush the balls in a little olive oil, as you put them on a baking tray lined with baking paper. Bake for 15–18 minutes until golden, turning partway through.
6) While you are waiting, making the tahini sauce by combining the tahini sauce ingredients in a high-speed blender and processing on high until smooth. If you do not have a small enough blender (a bullet-style blender should work for this), then do it manually, which means you’ll have to crush the garlic all the way into a smooth paste, such as with a pestle and mortar, or alternatively, use ready-made garlic paste—and then simply whisk the ingredients together until smooth.
7) Serve the falafels warm or cold, on flatbreads with leafy salad and the tahini sauce.
Enjoy!
