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
❝Hey Sheila – As always, your articles are superb !! So, I have a topic that I’d love you guys to discuss: green tea. I used to try + drink it years ago but I always got an allergic reaction to it. So the question I’d like answered is: Will I still get the same allergic reaction if I take the capsules ? Also, because it’s caffeinated, will taking it interfere with iron pills, other vitamins + meds ? I read that the health benefits of the decaffeinated tea/capsules are not as great as the caffeinated. Any info would be greatly appreciated !! Thanks much !!❞
Hi! I’m not Sheila, but I’ll answer this one in the first person as I’ve had a similar issue:
I found long ago that taking any kind of tea (not herbal infusions, but true teas, e.g. green tea, black tea, red tea, etc) on an empty stomach made me want to throw up. The feeling would subside within about half an hour, but I learned it was far better to circumvent it by just not taking tea on an empty stomach.
However! I take an l-theanine supplement when I wake up, to complement my morning coffee, and have never had a problem with that. Of course, my physiology is not your physiology, and this “shouldn’t” be happening to either of us in the first place, so it’s not something there’s a lot of scientific literature about, and we just have to figure out what works for us.
This last Monday I wrote (inspired in part by your query) about l-theanine supplementation, and how it doesn’t require caffeine to unlock its benefits after all, by the way. So that’s that part in order.
I can’t speak for interactions with your other supplements or medications without knowing what they are, but I’m not aware of any known issue, beyond that l-theanine will tend to give a gentler curve to the expression of some neurotransmitters. So, if for example you’re talking anything that affects that (e.g. antidepressants, antipsychotics, ADHD meds, sleepy/wakefulness meds, etc) then checking with your doctor is best.

We looked at 700 plant-based foods to see how healthy they really are. Here’s what we found
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.
If you’re thinking about buying plant-based foods, a trip to the supermarket can leave you bewildered.
There are plant-based burgers, sausages and mince. The fridges are loaded with non-dairy milk, cheese and yoghurt. Then there are the tins of beans and packets of tofu.
But how much is actually healthy?
Our nutritional audit of more than 700 plant-based foods for sale in Australian supermarkets has just been published. We found some products are so high in salt or saturated fat, we’d struggle to call them “healthy”.
We took (several) trips to the supermarket
In 2022, we visited two of each of four major supermarket retailers across Melbourne to collect information on the available range of plant-based alternatives to meat and dairy products.
We took pictures of the products and their nutrition labels.
We then analysed the nutrition information on the packaging of more than 700 of these products. This included 236 meat substitutes, 169 legumes and pulses, 50 baked beans, 157 dairy milk substitutes, 52 cheese substitutes and 40 non-dairy yoghurts.
Plant-based meats were surprisingly salty
We found a wide range of plant-based meats for sale. So, it’s not surprising we found large variations in their nutrition content.
Sodium, found in added salt and which contributes to high blood pressure, was our greatest concern.
The sodium content varied from 1 milligram per 100 grams in products such as tofu, to 2,000mg per 100g in items such as plant-based mince products.
This means we could eat our entire daily recommended sodium intake in just one bowl of plant-based mince.
An audit of 66 plant-based meat products in Australian supermarkets conducted in 2014 found sodium ranged from 316mg in legume-based products to 640mg in tofu products, per 100g. In a 2019 audit of 137 products, the range was up to 1,200mg per 100g.
In other words, the results of our audit seems to show a consistent trend of plant-based meats getting saltier.
Looking for plant-based meat? Check the label for the sodium content.

What about plant-based milks?
Some 70% of the plant-based milks we audited were fortified with calcium, a nutrient important for bone health.
This is good news as a 2019-2020 audit of 115 plant-based milks from Melbourne and Sydney found only 43% of plant-based milks were fortified with calcium.
Of the fortified milks in our audit, almost three-quarters (73%) contained the recommended amount of calcium – at least 100mg per 100mL.
We also looked at the saturated fat content of plant-based milks.
Coconut-based milks had on average up to six times higher saturated fat content than almond, oat or soy milks.
Previous audits also found coconut-based milks were much higher in saturated fat than all other categories of milks.
Some plant-based milks were healthier than others.

A first look at cheese and yoghurt alternatives
Our audit is the first study to identify the range of cheese and yoghurt alternatives available in Australian supermarkets.
Calcium was only labelled on a third of plant-based yoghurts, and only 20% of supermarket options met the recommended 100mg of calcium per 100g.
For plant-based cheeses, most (92%) were not fortified with calcium. Their sodium content varied from 390mg to 1,400mg per 100g, and saturated fat ranged from 0g to 28g per 100g.
So, what should we consider when shopping?
As a general principle, try to choose whole plant foods, such as unprocessed legumes, beans or tofu. These foods are packed with vitamins and minerals. They’re also high in dietary fibre, which is good for your gut health and keeps you fuller for longer.
If opting for a processed plant-based food, here are five tips for choosing a healthier option.
1. Watch the sodium
Plant-based meat alternatives can be high in sodium, so look for products that have around 150-250mg sodium per 100g.
2. Pick canned beans and legumes
Canned chickpeas, lentils and beans can be healthy and low-cost additions to many meals. Where you can, choose canned varieties with no added salt, especially when buying baked beans.
3. Add herbs and spices to your tofu
Tofu can be a great alternative to meat. Check the label and pick the option with the highest calcium content. We found flavoured tofu was higher in salt and sugar content than minimally processed tofu. So it’s best to pick an unflavoured option and add your own flavours with spices and herbs.
4. Check the calcium
When choosing a non-dairy alternative to milk, such as those made from soy, oat, or rice, check it is fortified with calcium. A good alternative to traditional dairy will have at least 100mg of calcium per 100g.
5. Watch for saturated fat
If looking for a lower saturated fat option, almond, soy, rice and oat varieties of milk and yoghurt alternatives have much lower saturated fat content than coconut options. Pick those with less than 3g per 100g.

Crispy Tempeh & Warming Mixed Grains In Harissa Dressing
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.
Comfort food that packs a nutritional punch! Lots of protein, fiber, vitamins, minerals, and healthy fats, and more polyphenols than you can shake a fork at.
You will need
- 1 lb cooked mixed whole grains (your choice what kind; gluten-free options include buckwheat, quinoa, millet)
- 7 oz tempeh, cut into ½” cubes
- 2 red peppers, cut into strips
- 10 baby plum tomatoes, halved
- 1 avocado, pitted, peeled, and diced
- 1 bulb garlic, paperwork done but cloves left whole
- 1 oz black olives, pitted and halved
- 4 tbsp extra virgin olive oil
- 2 tbsp harissa paste
- 2 tbsp soy sauce (ideally tamari)
- 1 tbsp nutritional yeast
- 1 tbsp chia seeds
- 2 tsp black pepper, coarse ground
- 1 tsp red chili flakes
- 1 handful chopped fresh flat-leaf parsley
- ½ tsp MSG or 1 tsp low-sodium salt
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 400℉ / 200℃.
2) Combine the red pepper strips with the tomatoes, garlic, 2 tbsp of the olive oil, and the MSG/salt, tossing thoroughly to ensure an even coating. Spread them on a lined baking tray, and roast for about 25 minutes. Remove when done, and allow to cool a little.
3) Combine the tempeh with the soy sauce and nutritional yeast flakes, tossing thoroughly to ensure an even coating. Spread them on a lined baking tray, and roast for about 25 minutes, tossing regularly to ensure it is crispy on all sides. If you get started on the tempeh as soon as the vegetables are in the oven, these should be ready only a few minutes after the vegetables.
4) Whisk together the remaining olive oil and harissa paste in a small bowl, to make the dressing,
5) Mix everything in a big serving bowl. By “everything” we mean the roasted vegetables, the crispy tempeh, the mixed grains, the dressing, the chia seeds, the black pepper, the red chili flakes, and the flat leaf parsley.
6) Serve warm.
Enjoy!

Proteins Of The Week

This week’s news round-up is, entirely by chance, somewhat protein-centric in one form or another. So, check out the bad, the very bad, the mostly good, the inconvenient, and the worst:
Mediterranean diet vs the menopause
Researchers looked at hundreds of women with an average age of 51, and took note of their dietary habits vs their menopause symptoms. Most of them were consuming soft drinks and red meat, and not good in terms of meeting the recommendations for key food groups including vegetables, legumes, fruit, fish and nuts, and there was an association between greater adherence to Mediterranean diet principles, and better health.

Listeria in meat
This one’s not a study, but it is relevant important news. The headline pretty much says it all, so if you don’t eat meat, this isn’t one you need to worry about any further than that. If you do eat meat, though, you might want to check out the below article to find out whether the meat you eat might be carrying listeria:

Brawn and brain?
A study looked at cognitively healthy older adults (of whom, 57% women), and found an association between their muscle strength and their psychological wellbeing. Note that when we said “cognitively healthy”, this means being free from dementia etc—not necessarily psychologically health in all respects, such as also being free from depression and enjoying good self-esteem.

The protein that blocks bone formation
This one’s more clinical but definitely of interest to any with osteoporosis or at high risk of osteoporosis. Researchers identified a specific protein that blocks osteoblast function, thus more of this protein means less bone production. Currently, this is not something that we as individuals can do anything about at home, but it is promising for future osteoporosis meds development.

Rabies risk
People associate rabies with “rabid dogs”, but the biggest rabies threat is actually bats, and they don’t even need to necessarily bite you to confer the disease (it suffices to have licked the skin, for instance—and bats are basically sky-puppies who will lick anything). Because rabies has a 100% fatality rate in unvaccinated humans, this is very serious. This means that if you wake up and there’s a bat in the house, it doesn’t matter if it hasn’t bitten anyone; get thee to a hospital (where you can get the vaccine before the disease takes hold; this will still be very unpleasant but you’ll probably survive so long as you get the vaccine in time).

Just One Heart – by Dr. Jonathan Fisher
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.
First, what this is not: a book to say eat fiber, go easy on the salt, get some exercise, and so forth.
What this rather is: a book about the connection between the heart and mind; often written poetically, the simple biological reality is that our emotional state does have a genuine impact on our heart health, and as such, any effort to look after our heart (healthwise) would be incomplete without an effort to look after our heart (emotionally).
Dr. Fisher talks about the impact of stress and uncertainty, as well as peace and security, on heart health—and then, having sorted emotional states into “heart breakers” and “heart wakers”, he goes about laying out a plan for what is, emotionally and thus also physiologically, good for our heart.
Chapter by chapter, he walks us through the 7 principles to live by:
- Steadiness: how to steady your heart amid chaos
- Wisdom: how to develop a wise heart in uncertain times
- Openness: how to safely open your heart in a threatening world
- Wholeness: how to show up with your whole heart without going to pieces
- Courage: how to lead with a courageous heart when fear surrounds you
- Lightness: how to live with a light heart in a heavy world
- Warmth: how to love with a warm heart when life feels cold
The style is anything but clinical; it’s well-written, certainly, and definitely informed in part by his medical understanding of the heart, but it’s entirely the raw human element that shines throughout, and that makes the ideas a lot more tangible.
Bottom line: if you’d like your heart to be healthy (cardiac health) and your heart to be healthy (emotional health), this book is a very worthwhile read.

Magnesium Glycinate vs Magnesium Citrate – 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 magnesium glycinate to magnesium citrate, we picked the citrate.
Why?
Both are fine sources of magnesium, a nutrient in which it’s very common to be deficient—a lot of people don’t eat many leafy greens, beans, nuts, and so forth that contain it.
A quick word on a third contender we didn’t include here: 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.
Magnesium glycinate and magnesium citrate are both absorbed well, but magnesium citrate is the most well-absorbed form of magnesium supplement.
In terms of the relative merits of the glycine or the citric acid (the “other part” of magnesium glycinate and magnesium citrate, respectively), both are also great nutrients, but the amount delivered with the magnesium is quite small in each case, and so there’s nothing here to swing it one way or the other.
For this reason, we went with the magnesium citrate, as the most readily bioavailable!

Non-Sleep Deep Rest: A Neurobiologist’s Take
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 get many benefits of sleep, while awake!
Today we’re talking about Dr. Andrew Huberman, a neuroscientist and professor in the department of neurobiology at Stanford School of Medicine.
He’s also a popular podcaster, and as his Wikipedia page notes:
❝In episodes lasting several hours, Huberman talks about the state of research in a specific topic, both within and outside his specialty❞
Today, we won’t be taking hours, and we will be taking notes from within his field of specialty (neurobiology). Specifically, in this case:
Non-Sleep Deep Rest (NSDR)
What is it? To quote from his own dedicated site on the topic:
❝What is NSDR (Yoga Nidra)? Non-Sleep Deep Rest, also known as NSDR, is a method of deep relaxation developed by Dr. Andrew Huberman, a neuroscientist at Stanford University School of Medicine.
It’s a process that combines controlled breathing and detailed body scanning to bring you into a state of heightened awareness and profound relaxation. The main purpose of NSDR is to reduce stress, enhance focus, and improve overall well-being.❞
While it seems a bit bold of Dr. Huberman to claim that he developed yoga nidra, it is nevertheless reassuring to get a neurobiologist’s view on this:
How it works, by science
Dr. Huberman says that by monitoring EEG readings during NSDR, we can see how the brain slows down. Measurably!
- It goes from an active beta range of 13–30 Hz (normal waking) to a conscious meditation state of an alpha range of 8–13 Hz.
- However, with practice, it can drop further, into a theta range of 4–8 Hz.
- Ultimately, sustained SSDR practice can get us to 0.5–3 Hz.
This means that the brain is functioning in the delta range, something that typically only occurs during our deepest sleep.
You may be wondering: why is delta lower than theta? That’s not how I remember the Greek alphabet being ordered!
Indeed, while the Greek alphabet goes alpha beta gamma delta epsilon zeta eta theta (and so on), the brainwave frequency bands are:
- Gamma = concentrated focus, >30 Hz
- Beta = normal waking, 13–30 Hz
- Alpha = relaxed state, 8–13 Hz
- Theta = light sleep, 4–8 Hz
- Delta = deep sleep, 1–4 Hz
Source: Sleep Foundation ← with a nice infographic there too
NSDR uses somatic cues to engage our parasympathetic nervous system, which in turn enables us to reach those states. The steps are simple:
- Pick a time and place when you won’t be disturbed
- Lie on your back and make yourself comfortable
- Close your eyes as soon as you wish, and now that you’ve closed them, imagine closing them again. And again.
- Slowly bring your attention to each part of your body in turn, from head to toe. As your attention goes to each part, allow it to relax more.
- If you wish, you can repeat this process for another wave, or even a third.
- Find yourself well-rested!
Note: this engagement of the parasympathetic nervous system and slowing down of brain activity accesses restorative states not normally available while waking, but 10 minutes of NSDR will not replace 7–9 hours of sleep; nor will it give you the vital benefits of REM sleep specifically.
So: it’s an adjunct, not a replacement
