Professional athlete & coach Audrey Burgio covers how to get a full-body workout that will make you stronger and more flexible (there are stretches here too, and many exercises are about strength and suppleness), as well as building stability and balance. In short, more robust and with better mobility.
Which is one of the best things about kettlebell training—unlike dumbbells and barbells, a kettlebell requires the kind of strength that one has to use when doing many routine tasks, from carrying the groceries to moving a big pan in the kitchen.
Because it is otherwise absolutely possible to look like Arnold Schwarzenegger in the gym, and then still pull a muscle moving something at home because the angle was awkward or somesuch!
However, making one’s body so robust does require training safely, and the clear instructions in this book will help the reader avoid injuries that might otherwise be incurred by just picking up some kettlebells and guessing.
Bottom line: if you’d like to get strong and supple from the comfort of your own home, this book can definitely lead the way!

Blood-Brain Barrier Breach Blamed For Brain-Fog
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.
Move Over, Leaky Gut. Now It’s A Leaky Brain.
…which is not a headline that promises good news, and indeed, the only good news about this currently is “now we know another thing that’s happening, and thus can work towards a treatment for it”.
Back in February (most popular media outlets did not rush to publish this, as it rather goes against the narrative of “remember when COVID was a thing?” as though the numbers haven’t risen since the state of emergency was declared over), a team of Irish researchers made a discovery:
❝For the first time, we have been able to show that leaky blood vessels in the human brain, in tandem with a hyperactive immune system may be the key drivers of brain fog associated with long covid❞
~ Dr. Matthew Campbell (one of the researchers)
Let’s break that down a little, borrowing some context from the paper itself:
- the leaky blood vessels are breaching the blood-brain-barrier
- that’s a big deal, because that barrier is our only filter between our brain and Things That Definitely Should Not Go In The Brain™
- a hyperactive immune system can also be described as chronic inflammation
- in this case, that includes chronic neuroinflammation which, yes, is also a major driver of dementia
You may be wondering what COVID has to do with this, and well:
- these blood-brain-barrier breaches were very significantly associated (in lay terms: correlated, but correlated is only really used as an absolute in write-ups) with either acute COVID infection, or Long Covid.
- checking this in vitro, exposure of brain endothelial cells to serum from patients with Long Covid induced the same expression of inflammatory markers.
How important is this?
As another researcher (not to mention: professor of neurology and head of the school of medicine at Trinity) put it:
❝The findings will now likely change the landscape of how we understand and treat post-viral neurological conditions.
It also confirms that the neurological symptoms of long covid are measurable with real and demonstrable metabolic and vascular changes in the brain.❞
~ Dr. Colin Doherty (see mini-bio above)

Beyond the obvious “get protected when offered boosters/updates” (see also: The Truth About Vaccines), other good practices include the same things most people were doing when the pandemic was big news, especially avoiding enclosed densely-populated places, washing hands frequently, and looking after your immune system.

Ozempic vs Five Natural Supplements
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.
Semaglutide (GLP-1 agonist) drugs Ozempic and Wegovy really do work for losing weight, provided one then remains on these expensive drugs for life. Dr. Jin Sung recommends a supplements-based approach, instead.
Natural Alternatives
Dr. Sung recommends:
- Berberine, which increases production and secretion of GLP-1.
- Probiotics, which increase GLP-1 secretion. In particular he recommends Akkermansia municiphila which secretes P9, and this protein stimulates GLP-1 production and secretion.
- Psyllium, a soluble dietary fiber which will increase short-chain fatty acids which then help with increasing GLP-1.
- Curcumin, which enhances L-cell numbers, in turn promoting and increasing GLP-1 secretion. Also, curcumin may prolong gastric emptying, and increase insulin sensitivity.
- Ginseng, of which the bioactive compound stimulates secretion of GLP-1, and also has anti-diabetic effects.
Dr. Sung explains more about each of these in his video:

Monosodium Glutamate: Sinless Flavor-Enhancer Or Terrible Health Risk?
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’s The Deal With MSG?
There are a lot of popular beliefs about MSG. Is there a grain of truth, or should we take them with a grain of salt? We’ll leap straight into myth-busting:
MSG is high in salt
True (technically) False (practically)
- MSG is a salt (a monosodium salt of L-glutamic acid), but to call it “full of salt” in practical terms is like calling coffee “full of fruit”. (Coffee beans are botanically fruit)
- It does contain sodium, though which is what the S stands for!
- We talked previously about how MSG’s sodium content is much lower than that of (table) salt. Specifically, it’s about one third of that of sodium chloride (e.g. table salt).
MSG triggers gluten sensitivity
False!
Or at least, because this kind of absolute negative is hard to prove in science, what we can say categorically is: it does not contain gluten. We understand that the similar name can cause that confusion. However:
- Gluten is a protein, found in wheat (and thus wheat-based foods).
- Glutamate is an amino acid, found in protein-rich foods.
- If you’re thinking “but proteins are made from amino acids”, yes, they are, but the foundational amino acid of gluten is glutamine, not glutamate. Different bricks → different house!
The body can’t process MSG correctly
False!
The body has glutamate receptors throughout the gut and nervous system.
The body metabolizes glutamate from MSG just the same as from any other food that contains it naturally.

MSG causes “Chinese Restaurant Syndrome”
False!
Racism causes that. It finds its origins in what was originally intended as a satirical joke, that the papers picked up and ran with, giving it that name in the 1960s. As to why it grew and persisted, that has more to do with US politics (the US has been often at odds with China for a long time) and xenophobia (people distrust immigrants, such as those who opened restaurants), including nationalistic rhetoric associating immigrants with diseases.
Read: Xenophobia in America in the Age of Coronavirus and Beyond ← academic paper that gives quite a compact yet comprehensive overview
Research science, meanwhile, has not found any such correlation, in more than 40 years of looking.
PS: we realize this item in the list is very US-centric. Apologies to our non-US subscribers. We know that this belief isn’t so much of a thing outside the US—though it certainly can crop up elsewhere sometimes, too.
Are there any health risks associated with MSG, then?
Well, as noted, it does contain sodium, albeit much less than table salt. So… do go easy on it, all the same.
Aside from that, the LD50 (a way of measuring toxicity) of MSG is 15.8g/kg, so if for example you weigh 150lb (68 kg), don’t eat 2.2lb (a kilogram) of MSG.
There have been some studies on rats (or in one case, fruit flies) that found high doses of MSG could cause heart problems and/or promote obesity. However:
- this has not been observed to be the case in humans
- those doses were really high, ranging from 1g/kg to 8g/kg. So that’d be the equivalent of our 150lb person eating it by the cupful
- it was injected (as a solution) into the rats, not ingested by them
- so don’t let someone inject you with a cup of MSG!
Read: A review of the alleged health hazards of monosodium glutamate
Bottom line on MSG and health:
Enjoy in moderation, but enjoy if you wish! MSG is just the salt form of the amino acid glutamate, which is found naturally in many foods, including shrimp, seaweed, and tomatoes.
Scientists have spent more than 40 years trying to find health risks for MSG, and will probably keep trying (which is as science should be), but for now… Everything has either come up negative, or has been the result of injecting laboratory animals with megadoses.
If you’d like to try it in your cooking as a low-sodium way to bring out the flavor of your dishes, you can order it online. Cheapest in bulk, but try it and see if you like it first!
(I’ll be real with you… I have 5 kg in the pantry myself and use about half a teaspoon a day, cooking for two)

Celery vs Rhubarb – 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 celery to rhubarb, we picked the rhubarb.
Why?
In terms of macros, rhubarb has more carbs and fiber, the ratio of which give it the lower glycemic index, though both are low glycemic index foods. This means this category is a very marginal win for rhubarb.
When it comes to vitamins, rhubarb has more vitamin C, while celery has more of vitamins A, B5, B6, and B9. A win for celery, this time.
In the category of minerals, rhubarb has more calcium, iron, magnesium, manganese, potassium, and selenium, while celery has more copper and phosphorus. This one’s a win for rhubarb.
Let’s give a quick nod also to polyphenols; rhubarb has more by overall quantity, and more in terms of “more useful to humans” too, being rich in an assortment of flavanols while celery must make do with some furanocoumarins.
In short, enjoy either or both, but nutritional density is a great reason to get some rhubarb in!

Exercises for Sciatica Pain Relief
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.
Jessica Valant is a physiotherapist and Pilates teacher, and today she’s going to demonstrate some exercise that relieve (and also correct the cause of) sciatica pain.
Back to good health
You will need a large strap for one of these exercises; a Pilates strap is great, but you can also use a towel. The exercises are:
Pelvic Rocking Exercise:
- Lie on your back, feet flat, knees bent.
- Gently rock your pelvis forwards and backwards (50% effort, no glute squeezing).
Leg Stretch with Strap:
- Straighten your left leg and loop the strap around the ball of your right foot.
- Gently straighten and bend your right leg while holding the strap.
- Perform a “nerve glide” by flexing and pointing your foot (not a stretch, just gentle movement).
- Repeat on the left leg.
Piriformis Stretch:
- Bend your right knee and place your left ankle over it (figure-four position).
- For a deeper stretch, hold your right thigh and pull your legs inwards.
Lower Back Release:
- Let your legs fall gently to one side after stretching each leg, opening the lower back.
Back Extension:
- Lie on your belly, placing your elbows down, palms flat.
- Optional: push up slightly into a back bend if it feels comfortable.
Seated Stretching:
- Finish by sitting cross-legged or on a chair.
- Inhale while raising your arms up, exhale while lowering them down, then reach sideways with your arms to stretch.
- Perform gentle neck stretches by tilting your ear to your shoulder on each side.
She recommends doing these exercises daily for at least a few weeks, though you should start to see improvement in your symptoms immediately. Nothing here should cause a problem or make things worse, but if it does, stop immediately and consult a local physiotherapist for more personalized advice.

❝Loved the info on nuts; of course I always eat pecans, which didn’t make the list of healthy nuts!❞
Dear subscriber, pardon the paraphrase of your comment—somehow it got deleted and now exists only in this writer’s memory. However, to address it:
Pecans are great too! We can’t include everything in every article (indeed, we got another feedback the same day saying the article was too long), but we love when you come to us with stuff for us to look at and write about (seriously, writer here: the more you ask, the easier it makes my job), so let’s talk pecans for a moment:
Pecans would have been number six on our list if we’d have written more!
Like many nuts, they’ve an abundance of healthy fats, fiber, vitamins, and minerals.
They’re particularly good for zinc, which is vital for immune function, healing (including normal recovery after normal exercise), and DNA synthesis (so: anti-aging).
Pecans are also great for reducing LDL (“bad” cholesterol) and triglycerides (which are also bad for heart health); check it out:
