So, no question/request too big or small
❝Do we really need pores, and why are they bigger on the face?❞
Pores secrete sweat or sebum (there are different kinds of pores for each).
If we didn’t have sweat pores, we’d be unable to sweat, which superficially may seem like a bonus, but it’d make us prone to overheating (like dogs, pigs, and other mammals that cannot sweat).
If we didn’t have sebum pores (usually called hair follicles, which are supplied by a sebaceous gland), we’d be completely hairless, and also unable to supply our skin with natural oils that keep it healthy. So we’d have no hair and very unhappy skin.
Which is ironic, because to believe beauty magazines, we must at all costs minimize our pores (and indeed, interventions like botox* can kill them).
*Let’s give that its full name though:
Suffice it to say, we do not recommend getting injected with neurotoxins unless it is truly necessary to ward off a greater harm.
As for being bigger on the face, they need not be, but sebaceous glands are more active and numerous there, being most active and numerous in the face/forehead—which is why oily skin is more likely to appear there than other parts of the body.
If your facial sebaceous glands are too active for your liking…
…there are ways to reduce that, a simple and relatively gentle way (relative, for example, botox) is with retinoids, including retinols or retinoic acids. Here’s some of the science of that; the paper is about treating acne, but the mechanism of action is the same (down-regulating the sebaceous glands’ action):
The potential side-effects, however were noted as:
- Cheilitis
- Desquamation of the skin
- Pruritus
Which, in translation from sciencese, means:
- Chapped lips
- Flaky skin
- Itchiness
Which aren’t necessarily fun, which is why with retinoids are best taken in very small doses at first to see how your skin reacts.
Remember when we said what your skin would be like without pores? This is what would happen, only much worse.
Take care!

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.
❝Can you do something on collagen and keep use posted on pineapple, and yes love and look forward to each issue❞
Glad you’re enjoying! We did write a main feature on collagen a little while back! Here it is:
We Are Such Stuff As Fish Are Made Of
As for pineapple, there’s not a lot to keep you posted about! Pineapple’s protein-digesting, DNA-unzipping action is well-established and considered harmless (if your mouth feels weird when you eat pineapple or drink pineapple juice, this is why, by the way) because no meaningful damage was done.
For example:
- Pineapple’s bromelain action is akin to taking apart a little lego model brick by brick (easy to fix)
- Clastogenic genotoxicity is more like taking a blowtorch to the lego model (less easy to fix)
Fun fact: pineapple is good against inflammation, because of the very same enzyme!
❝I never knew anything about the l- tea. Where can I purchase it?❞
You can get it online quite easily! Here’s an example on Amazon
❝The 3 most important exercises don’t work if you can’t get on the floor. I’m 78, and have knee replacements. What about 3 best chair yoga stretches? Love your articles!❞
Here are six!

Heavy Metal Detox In A Pill?
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.
We have previous discussed assorted approaches to “detoxing”:
Detox: What’s Real, What’s Not, What’s Useful, What’s Dangerous?
Today we’re going to be looking at one we didn’t cover there, which is zeolite.
What is zeolite?
Zeolite is a mineral that occurs naturally and can also be synthesized, and it’s famous for absorbing other stuff from around it. Because of this property, it’s used in many things, including:
- Petrochemical catalysis
- Water treatment
- Nuclear waste reprocessing
- Cat litter
- Supplements (for detox purposes)
That’s, uh… An interesting list, isn’t it? So, we were curious as to whether this mineral that’s also used in fish tank filters is, in fact, overpriced gravel being sold to the gullible as a health supplement.
We had to do some digging on this one
Our journey didn’t start well, with this very dubious-looking paper being cited by a company selling zeolite supplements:
This immediately prompted two questions:
- Who is eating graphene?!* That stuff does not occur in nature (or at least; it hasn’t ever been found; the universe is a big place so it might exist elsewhere), has only relatively recently been synthesized, is very difficult to produce, is two-dimensional while being hard as diamonds, and exists only in truly tiny lab-made quantities worldwide. It would be orders of magnitude easier to find and eat uranium.
- Is this a reputable journal? Which question was easier to answer than the former one, and the answer is “no”; we hadn’t heard of this journal (ACTA Scientific), and neither it seems had most of the Internet, but we did find it on a list of predatory journals, here.
*The citation given in the above paper should by rights answer the question of who is eating graphene, since by rights they must have demonstrated it somehow, but it just doesn’t. Instead, it links to what it claims is a paper titled “Oxygenated Zeolite (Clinoptilite) Efficiently Removes Aluminum & Graphene Oxide”, but is in reality just someone’s blog post with a screenshot of an actual paper entitled “Novel, oxygenated clinoptilolite material efficiently removes aluminium from aluminium chloride-intoxicated rats in vivo”). Looking up this real paper in its real journal, it does not mention graphene.
All this to say: sometimes, unscrupulous people will just plain lie to you, which is why peer review is important, as is sourcing data from reputable journals. Which is what we do for you so that you don’t have to 🙂
It does, actually, work though (for heavy metal detox)
Notwithstanding the aforementioned bunk, we found this from a more reputable publisher:
❝In this study, we have presented clinical evidence supporting the use of an activated clinoptilolite (zeolite) suspension to safely and effectively increase the urinary excretion of potentially toxic heavy metals in healthy volunteers without negatively impacting the electrolyte profiles of the participants.
Significant increases in the urinary excretion of aluminum, antimony, arsenic, bismuth, cadmium, lead, mercury, nickel and tin were observed in the subjects participating in the two study groups as compared to placebo controls.❞
Also good for the gut and against inflammation
Specifically, it’s good for gut barrier integrity, i.e., against “leaky gut syndrome”:
❝Twelve weeks of zeolite supplementation exerted beneficial effects on intestinal wall integrity as indicated via decreased concentrations of the tight junction modulator zonulin.
This was accompanied by mild anti-inflammatory effects in this cohort of aerobically trained subjects.❞
May also be good against neurodegenerative diseases
If it is (which is plausible), it’ll probably because of removing heavy metals and improving gut barrier integrity—in other words, the things we just looked at in the two reputable peer-reviewed studies we examined above.
But the science is young for this one; here’s the current state of things:
Zeolite and Neurodegenerative Diseases
Is it safe?
Safety reviews have found it to be safe, for example:
Critical Review on Zeolite Clinoptilolite Safety and Medical Applications in vivo
However, if you are taking regular medications, we recommend checking with your pharmacist or doctor to ensure that zeolite will not also remove those medications from your system!

Superfood Pesto Pizza
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Not only is this pizza full of foods that punch above their weight healthwise, there’s no kneading and no waiting when it comes to the base, either. Homemade pizzas made easy!
You will need
For the topping:
- 1 zucchini, sliced
- 1 red bell pepper, cut into strips
- 3 oz mushrooms, sliced
- 3 shallots, cut into quarters
- 6 sun-dried tomatoes, roughly chopped
- ½ bulb garlic (paperwork done, but cloves left intact, unless they are very large, in which case halve them)
- 1 oz pitted black olives, halved
- 1 handful arugula
- 1 tbsp extra virgin olive oil
- 2 tsp black pepper, coarse ground
- ½ tsp MSG or 1 tsp low-sodium salt
For the base:
- ½ cup chickpea flour (also called besan or gram flour)
- 2 tsp extra virgin olive oil
- ½ tsp baking powder
- ⅛ tsp MSG or ¼ tsp low-sodium salt
For the pesto sauce:
- 1 large bunch basil, chopped
- ½ avocado, pitted and peeled
- 1 oz pine nuts
- ¼ bulb garlic, crushed
- 2 tbsp nutritional yeast
- 1 tsp black pepper
- Juice of ½ lemon
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 400℉ / 200℃.
2) Toss the zucchini, bell pepper, mushrooms, shallots, and garlic cloves in 1 tbsp olive oil, ensuring an even coating. Season with the black pepper and MSG/salt, and put on a baking tray lined with baking paper, to roast for about 20 minutes, until they are slightly charred.
3) When the vegetables are in the oven, make the pizza base by combining the dry ingredients in a bowl, making a pit in the middle of it, adding the olive oil and whisking it in, and then slowly (i.e., a little bit at a time) whisking in 1 cup cold water. This should take under 5 minutes.
4) Don’t panic when this doesn’t become a dough; it is supposed to be a thick batter, so that’s fine. Pour it into a 9″ pizza pan, and bake for about 15 minutes, until firm. Rotate it if necessary partway through; whether it needs this or not will depend on your oven.
5) While the pizza base is in the oven, make the pesto sauce by blending all the pesto sauce ingredients in a high-speed blender until smooth.
6) When the base and vegetables are ready (these should be finished around the same time), spread the pesto sauce on the base, scatter the arugula over it followed by the vegetables and then the olives and sun-dried tomatoes.
7) Serve, adding any garnish or other final touches that take your fancy.
Enjoy!

Glutathione: More Than An Antioxidant
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.
Glutathione’s Benefits: The Usual And The Unique
Glutathione is a powerful antioxidant that does all the things we might reasonably expect an antioxidant to do, plus some beneficial quirks of its own.
We do make glutathione in our bodies, but we can also get it from our diet, and of course, we can also supplement it.
What foods is it in?
It’s in a lot of foods, but some top examples include:
- turmeric
- avocado
- asparagus
- almonds
- cruciferous vegetables
- watermelon
- garlic
For a fuller list and discussion, see:
What does it do?
Let’s start with the obvious; as with most things that are antioxidant, it is also anti-inflammatory. Increasing or decreasing glutathione levels is associated with decreased or increased inflammation, respectively. For example:
It being anti-inflammatory also means it can be beneficial in calming autoimmune disorders:
Glutathione: a key player in autoimmunity
And to complete the triad of “those three things that generally go together”, yes, this means it also has anticancer potential, but watch out!
❝Although in healthy cells [glutathione] is crucial for the removal and detoxification of carcinogens, elevated [glutathione] levels in tumor cells are associated with tumor progression and increased resistance to chemotherapeutic drugs❞
~ Dr. Miroslava Cuperlovic-Culf et al.
Read in full: Role of Glutathione in Cancer: From Mechanisms to Therapies
So in other words, when it comes to cancer risk management, glutathione is a great preventative, but the opposite of a cure.
What were those “beneficial quirks of its own”?
They are mainly twofold, and the first is that it improves insulin sensitivity. There are many studies showing this, but here’s a recent one from earlier this year:
The Role of Glutathione and Its Precursors in Type 2 Diabetes
The other main “beneficial quirk of its own” is that it helps prevent and/or reverse non-alcoholic fatty liver disease, as in this study from last year:
Because of glutathione’s presence in nuts, fruits, and vegetables, this makes it a great thing to work in tandem with a dietary approach to preventing/reversing NAFLD, by the way:
Anything else?
It’s being investigated as a potential treatment for Parkinson’s disease symptoms, but the science is young for this one, so there is no definitive recommendation yet in this case. If you’re interested in that, though, do check out the current state of the science at:
Potential use of glutathione as a treatment for Parkinson’s disease
Is it safe?
While there is no 100% blanket statement of safety that can ever be made about anything (even water can kill people, and oxygen ultimately kills everyone that something else doesn’t get first), glutathione has one of the safest general safety profiles possible, with the exception we noted earlier (if you have cancer, it is probably better to skip this one unless an oncologist or similar advises you otherwise).
As ever, do speak with your doctor/pharmacist to be sure in any case, though!

Luxurious Longevity Risotto
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.
Pearl barley is not only tasty and fiber-rich, but also, it contains propionic acid, which lowers cholesterol. The fiber content also lowers cholesterol too, of course, by the usual mechanism. The dish’s health benefits don’t end there, though; check out the science section at the end of the recipe!
You will need
- 2 cups pearl barley
- 3 cups sliced chestnut mushrooms
- 2 onions, finely chopped
- 6 large leaves collard greens, shredded
- ½ bulb garlic, finely chopped
- 8 spring onions, sliced
- 1½ quarts low-sodium vegetable stock
- 2 tbsp nutritional yeast
- 1 tbsp chia seeds
- 1 tbsp black pepper, coarse ground
- 1 tsp MSG or 2 tsp low-sodium salt
- 1 tsp rosemary
- 1 tsp thyme
- Extra virgin olive oil, for cooking
- Optional garnish: fresh basil leaves
Method
(we suggest you read everything at least once before doing anything)
1) Heat a little oil in a large sauté pan; add the onions and garlic and cook for 5 minutes; add the mushrooms and cook for another 5 minutes.
2) Add the pearl barley and a cup of the vegetable stock. Cook, stirring, until the liquid is nearly all absorbed, and add more stock every few minutes, as per any other risotto. You may or may not use all the stock you had ready. Pearl barley takes longer to cook than rice, so be patient—it’ll be worth the wait!
Alternative: an alternative is to use a slow cooker, adding a quart of the stock at once and coming back about 4 hours later—thus, it’ll take a lot longer, but will require minimal/no supervision.
3) When the pearl barley has softened, become pearl-like, and the dish is taking on a creamy texture, stir in the rest of the ingredients. Once the greens have softened, the dish is done, and it’s time to serve. Add the garnish if using one:
Enjoy!

Hardwiring Happiness – by Dr. Rick Hanson
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.
Publishers are very excitable about “the new science of…”, and it’s almost never actually a new science of. But what about in this case?
No, it isn’t. It’s the very well established science of! And that’s a good thing, because it means this book is able to draw on quite a lot of research and established understanding of how neuroplasticity works, to leverage that and provide useful guidance.
A particular strength of this book is that while it polarizes the idea that some people have “happy amygdalae” and some people have “sad amygdalae”, it acknowledges that it’s not just a fated disposition and is rather the result of the lives people have led… And then provides advice on upgrading from sad to happy, based on the assumption that the reader is quite possibly coming from a non-ideal starting point.
The bookdoes an excellent job of straddling neuroscience and psychology, which sounds like not much of a straddle (the two are surely very connected, after all, right?) but this does mean that we’re hearing about the chemical structure of DNA inside the nuclei of the neurons of the insula, not long after reading an extended gardening metaphor about growth, choices, and vulnerabilities.
Bottom line: if you’d like a guide to changing your brain for the better (happier) that’s not just “ask yourself: what if it goes well?” and similar CBTisms, then this is a fine book for you.
