In the Realm of Hungry Ghosts – by Dr. Gabor Maté

We’ve reviewed books by Dr. Maté before, and this one’s about addiction. We’ve reviewed books about addiction before too, so what makes this one different?
Wow, is this one so different. Most books about addiction are about “beating” it. Stop drinking, quit sugar, etc. And, that’s all well and good. It is definitely good to do those things. But this one’s about understanding it, deeply. Because, as Dr. Maté makes very clear, “there, but for the grace of epigenetics and environmental factors, go we”.
Indeed, most of us will have addictions; they’re (happily) just not too problematic for most of us, being either substances that are not too harmful (e.g. coffee), or behavioral addictions that aren’t terribly impacting our lives (e.g. Dr. Maté’s compulsion to keep buying more classical music, which he then tries to hide from his wife).
The book does also cover a lot of much more serious addictions, the kind that have ruined lives, and the kind that definitely didn’t need to, if people had been given the right kind of help—instead of, all too often, they got the opposite.
Perhaps the greatest value of this book is that; understanding what creates addiction in the first place, what maintains it, and what help people actually need.
Bottom line: if you’d like more insight into the human aspect of addiction without getting remotely wishy-washy, this book is probably the best one out there.

Are GMOs Good Or Bad For Us?
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.
Unzipping Our Food’s Genes
In yesterday’s newsletter, we asked you for your (health-related) views on GMOs.
But what does the science say?
First, a note on terms
Technically, we (humans) have been (g)enetically (m)odifying (o)rganisms for thousands of years.
If you eat a banana, you are enjoying the product of many generations of artificial selection, to change its genes to produce a fruit that is soft, sweet, high in nutrients, and digestible without cooking. The original banana plant would be barely recognizable to many people now (and also, barely edible). We’ve done similarly with countless other food products.
So in this article, we’re going to be talking exclusively about modern genetic modification of organisms, using exciting new (ish, new as in “in the last century”) techniques to modify the genes directly, in a copy-paste fashion.
For more details on the different kinds of genetic modification of organisms, and how they’re each done (including the modern kinds), check out this great article from Sciencing, who explain it in more words than we have room for here:
Sciencing | How Are GMOs Made?
(the above also offers tl;dr section summaries, which are great too)
GMOS are outright dangerous (cancer risks, unknown risks, etc): True or False?
False, so far as we know, in any direct* fashion. Obviously “unknown risks” is quite a factor, since those are, well, unknown. But GMOs on the market undergo a lot of safety testing, and have invariably passed happily.
*However! Glyphosate (the herbicide), on the other hand, has a terrible safety profile and is internationally banned in very many countries for this reason.
Why is this important? Because…
- in the US (and two out of ten Canadian provinces), glyphosate is not banned
- In the US (and we may hypothesize, those two Canadian provinces) one of the major uses of genetic modification of foodstuffs is to make it resistant to glyphosate
- Consequently, GMO foodstuffs grown in those places have generally been liberally doused in glyphosate
So… It’s not that the genetic modification itself makes the food dangerous and potentially carcinogenic (it doesn’t), but it is that the genetic modification makes it possible to use a lot more glyphosate without losing crops to glyphosate’s highly destructive properties.
Which results in the end-consumer eating glyphosate. Which is not good. For example:
❝Following the landmark case against Monsanto, which saw them being found liable for a former groundskeeper, 46 year old Dewayne Johnson’s cancer, 32 countries have to date banned the use of Glyphosate, the key ingredient in Monsanto’s Roundup weed killer. The court awarded Johnson R4.2 billion in damages finding Monsanto “acted with malice or oppression”.❞
Source: see below!
You can read more about where glyphosate is and isn’t banned, here:
33 countries ban the use of Glyphosate—the key ingredient in Roundup
For the science of this (and especially the GMO → glyphosate use → cancer pipeline), see:
Use of Genetically Modified Organism (GMO)-Containing Food Products in Children
GMOs are extra healthy because of the modifications (they were designed for that, right?): True or False?
True or False depending on who made them and why! As we’ve seen above, not all companies seem to have the best interests of consumer health in mind.
However, they can be! Here are a couple of great examples:
❝Recently, two genome-edited crops targeted for nutritional improvement, high GABA tomatoes and high oleic acid soybeans, have been released to the market.
Nutritional improvement in cultivated crops has been a major target of conventional genetic modification technologies as well as classical breeding methods❞

(note, they draw a distinction of meaning between genome editing and genetic modification, according to which of two techniques is used, but for the purposes of our article today, this is under the same umbrella)
Want to know more?

Successful Aging – by Dr. Daniel Levitin
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 all know about age-related cognitive decline. What if there’s a flipside, though?
Neuroscientist Dr. Daniel Levitin explores the changes that the brain undergoes with age, and notes that it’s not all downhill.
From cumulative improvements in the hippocampi to a dialling-down of the (often overfunctioning) amygdalae, there are benefits too.
The book examines the things that shape our brains from childhood into our eighties and beyond. Many milestones may be behind us, but neuroplasticity means there’s always time for rewiring. Yes, it also covers the “how”.
We learn also about the neurogenesis promoted by such simple acts as taking a different route and/or going somewhere new, and what other things improve the brain’s healthspan.
The writing style is very accessible “pop-science”, and is focused on being of practical use to the reader.
Bottom line: if you want to get the most out of your aging wizening brain, this book is a great how-to manual.

Lower Cholesterol Naturally
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.
Lower Cholesterol, Without Statins
We’ll start this off by saying that lowering cholesterol might not, in fact, be critical or even especially helpful for everyone, especially in the case of women. We covered this more in our article about statins:
…which was largely informed by the wealth of data in this book:
The Truth About Statins – by Dr. Barbara H. Roberts
…which in turn, may in fact put a lot of people off statins. We’re not here to tell you don’t use them—they may indeed be useful or even critical for some people, as Dr. Roberts herself also makes makes clear. But rather, we always recommend learning as much as possible about what’s going on, to be able to make the most informed choices when it comes to what often might be literally life-and-death decisions.
On which note, if anyone would like a quick refresher on cholesterol, what it actually is (in its various forms) and what it does, why we need it, the problems it can cause anyway, then here you go:
Now, with all that in mind, we’re going to assume that you, dear reader, would like to know:
- how to lower your LDL cholesterol, and/or
- how to maintain a safe LDL cholesterol level
Because, while the jury’s out on the dangers of high LDL levels for women in particular, it’s clear that for pretty much everyone, maintaining them within well-established safe zones won’t hurt.
Here’s how:
Relax
Or rather, manage your stress. This doesn’t just reduce your acute risk of a heart attack, it also improves your blood metrics along the way, and yes, that includes not just blood pressure and blood sugars, but even triglycerides! Here’s the science for that, complete with numbers:
What are the effects of psychological stress and physical work on blood lipid profiles?
With that in mind, here’s…
How To Manage Chronic Stress (Even While Chronically Stressed)
Not chemically “relaxed”, though
While relaxing is important, drinking alcohol and smoking are unequivocally bad for pretty much everything, and this includes cholesterol levels:
Can We Drink To Good Health? ← this also covers popular beliefs about red wine and heart health, and the answer is no, we cannot
As for smoking, it is good to quit as soon as possible, unless your doctor specifically advises you otherwise (there are occasional situations where something else needs to be dealt with first, but not as many some might like to believe):
Addiction Myths That Are Hard To Quit
If you’re wondering about cannabis (CBD and/or THC), then we’d love to tell you about the effect these things have on heart health in general and cholesterol levels in particular, but the science is far too young (mostly because of the historic, and in some places contemporary, illegality cramping the research), and we could only find small, dubious, mutually contradictory studies so far. So the honest answer is: science doesn’t know this one, yet.
Exercise… But don’t worry, you can still stay relaxed
When it comes to heart health, the most important thing is keeping moving, so getting in those famous 150 minutes per week of moderate exercise is critical, and getting more is ideal.
240 minutes per week is a neat 40 minutes per day, by the way and is very attainable (this writer lives a 20-minute walk away from where she does her daily grocery shopping, thus making for a daily 40-minute round trip, not counting the actual shopping).

If walking is for some reason not practical for you, here’s a whole list of fun options that don’t feel like exercise but are:
Manage your hormones
This one is mostly for menopausal women, though some people with atypical hormonal situations may find it applicable too.
Estrogen protects the heart… Until it doesn’t:

Here’s a great introduction to sorting it out, if necessary:

Eat a heart-healthy diet
Shocking nobody, but it has to be said, for the sake of being methodical. So, what does that look like?

You can also check out the DASH (Dietary Approaches to Stop Hypertension) edition of the Mediterranean diet, here:
Four Ways To Upgrade The Mediterranean Diet
As for saturated fat (and especially trans-fats), the basic answer is to keep them to minimal, but there is room for nuance with saturated fats at least:
Can Saturated Fats Be Healthy?
And lastly, do make sure to get enough omega 3 fatty-acids:

The Mind-Gut Connection – by Dr. Emeran Mayer
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’ve reviewed books about the mind-gut connection before, so what makes this one stand out?
Firstly, it’s a lot more comprehensive than the usual “please, we’re begging you, eat some fiber”.
And yes, of course that’s part of it. Prebiotics, probiotics, reduce fried and processed foods, reduce sugar/alcohol, reduce meat, and again, eat some greenery.
But where this book really comes into its own is looking more thoroughly at the gut microbiota and their function. Dr. Mayer goes well beyond “there are good and bad bacteria” and looks at the relationship each of them have with the body’s many hormones, and especially neurotransmitters like serotonin and dopamine.
He also looks at the two-way connection between brain and gut. Yes, our gut gives us “gut feelings”, but 10% of communication between the brain and gut is in the other direction; he explores what that means for us, too.
Finally, he does give a lot of practical advice, not just dietary but also behavioral, to make the most of our mind-gut connection and make it work for our health, rather than against it.
Bottom line: this is the best book on the brain-gut connection that this reviewer has read so far, and certainly the most useful if you already know about gut-healthy nutrition, and are looking to take your understanding to the next level.

What Happens To Your Body When You Plank 1 Minute Every Day
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.
Planks improve strength, flexibility, balance, posture, reduce chronic back pain, lower blood pressure, and enhance physique. But can we really get benefits from just 1 minute per day?
To the core
The benefits that can be expected, according to the science cited in this video, include:
- Within 2–3 weeks, daily planking of just 1 minute per day activates deep core muscles, enhancing balance, which helps in everyday tasks and prevents muscle imbalances.
- Strengthening core muscles through planks also helps alleviate lower back pain, with research supporting its effectiveness within 3 weeks.
- Posture is important for good health, and planks align the spine and hips, improving posture naturally, which also helps alleviate back issues. So, there’s a good kind of synergy to this exercise.
- Of course, many people exercising have the goal of a more toned body; regular planking leads to a toned core, sculpted shoulders, and leaner legs.
- For those who care more about mobility, though, planking enhances flexibility in hamstrings, feet, and toes within 4–6 weeks.
- Anything else? Yes, isometric exercises like planks are highly effective at reducing blood pressure, and, counterintuitively, more so than aerobic exercises.
The video also looks at a study in which participants did 20 minutes per day instead of 1, which predictably also significantly improved strength, endurance, flexibility, and reduced body fat.
However, another study cited gives the stats for just 1 minute daily, and that was not even a whole minute, so much as 30 seconds hold, 1 minute rest, 30 seconds hold—and still showed very good improvements.
