TED-x | Sugar Is Not A Treat

Dr. Jody Stanislaw offers a reframe:
Not so sweet
The pancreas isn’t an organ that most people think about a lot, but it regulates blood sugar levels by releasing insulin as needed. Overworking the beta cells in the pancreas that do this, can lead to their burnout, which contributes to prediabetes and type 2 diabetes.
If, like Dr. Stanislaw, you already have Type 1 Diabetes (an autoimmune condition usually diagnosed in early childhood and unrelated to what one has or hasn’t been eating), then your pancreas is already not doing much, or rather, it’s too busy fighting itself to actually do its job. This means that taking exogenous insulin (i.e., from the pharmacy rather than from your dysfunctional pancreas) will be necessary for survival. Most people with T1D will have an insulin pump if possible, to provide insulin as needed. Others will rely on injections.
So, does that mean that T1D is a free pass on the diabetes-related health risks of sugar, since after all, you already have diabetes anyway?
Nope, no such luck. Because in the case of T1D, if you then get insulin resistance on top of the fact you don’t make your own insulin, then the insulin that you are taking will stop working, and ultimately you will die. So, that’s pretty important to avoid!
Thus, Dr. Stanislaw has strong opinions on diet in this regard, and she recommends her own protocol regardless of whether you are diabetic or not:
- Avoid refined carbs (e.g. bread, pasta, or foods with added sugars).
- Start the day with protein-rich foods for balanced blood sugar.
- Drink water to curb sugar cravings caused by dehydration.
- Use low-carb substitutes (e.g. cauliflower pizza crust, zucchini noodles, etc).
While Dr. Stanislaw does recommend an 80:20 approach to eating in general (80% healthy foods, 20% indulgences), she does strongly suggest not putting sugar even into the “indulgences” 20%, because a) a diet of 20% sugar is not at all good, and b) the dangers of sugar consumption are particularly high, so it is better reframed not as a treat to be enjoyed, but rather as a threat to be avoided.

It’s Q&A Day at 10almonds!
Q: Can you let us know about more studies that have been done on statins? Are they really worth taking?
That is a great question! We imagine it might have been our recent book recommendation that prompted it? It’s quite a broad question though, so we’ll do that as a main feature in the near future!

The Exercises That Can Fix Sinus Problems (And More)

Who nose what benefits you will gain today?
This is James Nestor, a science journalist and author. He’s written for many publications, including Scientific American, and written a number of books, most notably Breath: The New Science Of A Lost Art.
Today we’ll be looking at what he has to share about what has gone wrong with our breathing, what problems this causes, and how to fix it.
What has gone wrong?
When it comes to breathing, we humans are the pugs of the primate world. In a way, we have the opposite problem to the squashed-faced dogs, though. But, how and why?
When our ancestors learned first tenderize food, and later to cook it, this had two big effects:
- We could now get much more nutrition for much less hunting/gathering
- We now did not need to chew our food nearly so much
Getting much more nutrition for much less hunting/gathering is what allowed us to grow our brains so large—as a species, we have a singularly large brain-to-body size ratio.
Not needing to chew our food nearly so much, meanwhile, had even more effects… And these effects have become only more pronounced in recent decades with the rise of processed food making our food softer and softer.
It changed the shape of our jaw and cheekbones, just as the size of our brains taking up more space in our skull moved our breathing apparatus around. As a result, our nasal cavities are anatomically ridiculous, our sinuses are a crime against nature (not least of all because they drain backwards and get easily clogged), and our windpipes are very easily blocked and damaged due to the unique placement of our larynx; we’re the only species that has it there. It allowed us to develop speech, but at the cost of choking much more easily.
What problems does this cause?
Our (normal, to us) species-wide breathing problems have resulted in behavioral adaptations such as partial (or in some people’s cases, total or near-total) mouth-breathing. This in turn exacerbates the problems with our jaws and cheekbones, which in turn exacerbates the problems with our sinuses and nasal cavities in general.
Results include such very human-centric conditions as sleep apnea, as well as a tendency towards asthma, allergies, and autoimmune diseases. Improper breathing also brings about a rather sluggish metabolism for how many calories we consume.
How are we supposed to fix all that?!
First, close your mouth if you haven’t already, and breathe through your nose.
In and out.
Both are important, and unless you are engaging in peak exercise, both should be through your nose. If you’re not used to this, it may feel odd at first, but practice, and build up your breathing ability.
Six seconds in and six seconds out is a very good pace.
If you’re sitting doing a breathing exercise, also good is four seconds in, four seconds hold, four seconds out, four seconds hold, repeat.
But those frequent holds aren’t practical in general life, so: six seconds in, six seconds out.
Through your nose only.
This has benefits immediately, but there are other more long-term benefits from doing not just that, but also what has been called (by Nestor, amongst many others), “Mewing”, per the orthodontist, Dr. John Mew, who pioneered it.
How (and why) to “mew”:
Place your tongue against the roof of your mouth. It should be flat against the palate; you’re not touching it with the tip here; you’re creating a flat seal.
Note: if you were mouth-breathing, you will now be unable to breathe. So, important to make sure you can breathe adequately through your nose first.
This does two things:
- It obliges nose-breathing rather than mouth-breathing
- It creates a change in how the muscles of your face interact with the bones of your face
In a battle between muscle and bone, muscle will always win.
Aim to keep your tongue there as much as possible; make it your new best habit. If you’re not eating, talking, or otherwise using your tongue to do something, it should be flat against the roof of your mouth.
You don’t have to exert pressure; this isn’t an exercise regime. Think of it more as a postural exercise, just, inside your mouth.
Quick note: read the above line again, because it’s important. Doing it too hard could cause the opposite problems, and you don’t want that. You cannot rush this by doing it harder; it takes time and gentleness.
Why would we want to do that?
The result, over time, will tend to be much healthier breathing, better sinus health, freer airways, reduced or eliminated sleep apnea, and, as a bonus, what is generally considered a more attractive face in terms of bone structure. We’re talking more defined cheekbones, straighter teeth, and a better mouth position.

Could Just Two Hours Sleep Per Day Be Enough?
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.
Polyphasic Sleep… Super-Schedule Or An Idea Best Put To Rest?
What is it?
Let’s start by defining some terms:
- Monophasic sleep—sleeping in one “chunk” per day. For example, a good night’s “normal” sleep.
- Biphasic sleep—sleeping in two “chunks” per day. Typically, a shorter night’s sleep, with a nap usually around the middle of the day / early afternoon.
- Polyphasic sleep—sleeping in two or more “chunks per day”. Some people do this in order to have more hours awake per day, to do things. The idea is that sleeping this way is more efficient, and one can get enough rest in less time. The most popular schedules used are:
- The Überman schedule—six evenly-spaced 20-minute naps, one every four hours, throughout the 24-hour day. The name is a semi-anglicized version of the German word Übermensch, “Superman”.
- The Everyman schedule—a less extreme schedule, that has a three-hours “long sleep” during the night, and three evenly-spaced 20-minute naps during the day, for a total of 4 hours sleep.
There are other schedules, but we’ll focus on the most popular ones here.
Want to learn about the others? Visit: Polyphasic.Net (a website by and for polyphasic sleep enthusiasts)
Some people have pointed to evidence that suggests humans are naturally polyphasic sleepers, and that it is only modern lifestyles that have forced us to be (mostly) monophasic.
There is at least some evidence to suggest that when environmental light/dark conditions are changed (because of extreme seasonal variation at the poles, or, as in this case, because of artificial changes as part of a sleep science experiment), we adjust our sleeping patterns accordingly.
The counterpoint, of course, is that perhaps when at the mercy of long days/nights at the poles, or no air-conditioning to deal with the heat of the day in the tropics, that perhaps we were forced to be polyphasic, and now, with modern technology and greater control, we are free to be monophasic.
Either way, there are plenty of people who take up the practice of polyphasic sleep.
Ok, But… Why?
The main motivation for trying polyphasic sleep is simply to have more hours in the day! It’s exciting, the prospect of having 22 hours per day to be so productive and still have time over for leisure.
A secondary motivation for trying polyphasic sleep is that when the brain is sleep-deprived, it will prioritize REM sleep. Here’s where the Überman schedule becomes perhaps most interesting:
The six evenly-spaced naps of the Überman schedule are each 20 minutes long. This corresponds to the approximate length of a normal REM cycle.
Consequently, when your head hits the pillow, you’ll immediately begin dreaming, and at the end of your dream, the alarm will go off.
Waking up at the end of a dream, when one hasn’t yet entered a non-REM phase of sleep, will make you more likely to remember it. Similarly, going straight into REM sleep will make you more likely to be aware of it, thus, lucid dreaming.
Read: Sleep fragmentation and lucid dreaming (actually a very interesting and informative lucid dreaming study even if you don’t want to take up polyphasic sleep)
Six 20-minute lucid-dreaming sessions per day?! While awake for the other 22 hours?! That’s… 24 hours per day of wakefulness to use as you please! What sorcery is this?
Hence, it has quite an understandable appeal.
Next Question: Does it work?
Can we get by without the other (non-REM) kinds of sleep?
According to Überman cycle enthusiasts: Yes! The body and brain will adapt.
According to sleep scientists: No! The non-REM slow-wave phases of sleep are essential
Read: Adverse impact of polyphasic sleep patterns in humans—Report of the National Sleep Foundation sleep timing and variability consensus panel
(if you want to know just how bad it is… the top-listed “similar article” is entitled “Suicidal Ideation”)
But what about, for example, the Everman schedule? Three hours at night is enough for some non-REM sleep, right?
It is, and so it’s not as quickly deleterious to the health as the Überman schedule. But, unless you are blessed with rare genes that allow you to operate comfortably on 4 hours per day (you’ll know already if that describes you, without having to run any experiment), it’s still bad.
Adults typically need 7–9 hours of sleep per night, and if you don’t get it, you’ll accumulate a sleep debt. And, importantly:
When you accumulate sleep debt, you are borrowing time at a very high rate of interest!
And, at risk of laboring the metaphor, but this is important too:
Not only will you have to pay it back soon (with interest), you will be hounded by the debt collection agents—decreased cognitive ability and decreased physical ability—until you pay up.
In summary:
- Polyphasic sleep is really very tempting
- It will give you more hours per day (for a while)
- It will give the promised lucid dreaming benefits (which is great until you start micronapping between naps, this is effectively a mini psychotic break from reality lasting split seconds each—can be deadly if behind the wheel of a car, for instance!)
- It is unequivocally bad for the health and we do not recommend it
Bottom line:
Some of the claimed benefits are real, but are incredibly short-term, unsustainable, and come at a cost that’s far too high. We get why it’s tempting, but ultimately, it’s self-sabotage.
(Sadly! We really wanted it to work, too…)

12 Foods That Fight Depression & Anxiety
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.
Food impacts mental health, and while it won’t magically cure mental illness, dietary changes can do a lot to improve mood. Here’s how:
Nutraceuticals
We’ll not keep the 12 nutraceutical foods a mystery; here’s what they are and a few words on how they work (in many cases, we could write whole articles about them; in some cases, we already have! You can find many of them by using the search function in the top-right of each page).
- Walnuts are rich in omega-3s for brain health; arguably the best nut for depression relief.
- Fermented foods because probiotics in foods like yogurt and sauerkraut support the gut-brain connection as well as serotonin production there, enhancing mood.
- Cherry tomatoes are rich in lycopene, which helps combat both depression and mood swings.
- Leafy greens reduce brain inflammation linked to depression.
- Apples and other fruit are high in fiber and antioxidants that stabilize blood sugar and mood, reducing brain inflammation.
- Beans are high in B vitamins, crucial for neurotransmitter production and mood regulation (without also being high in brain-harmful things, as red meat is).
- Berries are super-high antioxidants and cortisol-lowering anthocyanidins, promoting calmness and reducing stress.
- Oats contain the healthiest kind of fiber, β-glucan, and additionally help stabilize blood sugar and mood; they’re also rich in selenium, which boosts mood.
- Mushrooms help regulate blood sugar and act as prebiotics, supporting serotonin production in the gut.
- Avocados are famously rich in healthy fats, including omega-3s and oleic acid, which support brain health and combat depression.
- Dark chocolate contains antioxidants, magnesium, and gut-healthy prebiotics that indirectly reduce mental stress and improve brain function. Also a famous comfort food for many, of course, and that factor’s not to be overlooked either.
- Pumpkin seeds are rich in tryptophan, which boosts serotonin production. As a bonus, they also help some kinds of antidepressant to work better—check with your doctor or pharmacist to be sure in your case, though.

The Minimum Method – by Joey Thurman
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.
Trying to squeeze out an extra 0.5% from every effort in life can be exhausting, especially with diminishing marginal returns when it comes to linear increases in effort.
Surely there must be a sweet spot of getting the best returns on the least effort and call it a day?
That’s what this book is about. Thurman examines and explains how to get “the most for least” in various important areas of health, including diet, exercise, sleep, breathwork, recovery, and a chapter specifically on brain health, though of course all the aforementioned things do affect brain health too.
An interesting feature of the book is that at the end of each chapter, he’ll give different advice for different levels of experience/commitment, so that essentially there’s an easy/medium/hard way to proceed each time.
The style is light and personal, without much hard science. The advice given is nonetheless consistent with prevailing scientific consensus, and there are still occasional scientific references throughout, with links to appropriate studies. Mostly though, the focus is on being practical.
Bottom line: if you’ve been looking for a “most for least” way of going about health, this is a fine option.

Ideal Blood Pressure Numbers Explained
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.
It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
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
❝Maybe I missed it but the study on blood pressure did it say what the 2 numbers should read ideally?❞
We linked it at the top of the article rather than including it inline, as we were short on space (and there was a chart rather than a “these two numbers” quick answer), but we have a little more space today, so:
Category Systolic (mm Hg) Diastolic (mm Hg) Normal < 120 AND < 80 Elevated 120 – 129 AND < 80 Stage 1 – High Blood Pressure 130 – 139 OR 80 – 89 Stage 2 – High Blood Pressure 140 or higher OR 90 or higher Hypertensive Crisis Above 180 AND/OR Above 120 To oversimplify for a “these two numbers” answer, under 120/80 is generally considered good, unless it is under 90/60, in which case that becomes hypotension.
Hypotension, the blood pressure being too low, means your organs may not get enough oxygen and if they don’t, they will start shutting down.
To give you an idea how serious this, this is the closed-circuit equivalent of the hypovolemic shock that occurs when someone is bleeding out onto the floor. Technically, bleeding to death also results in low blood pressure, of course, hence the similarity.
So: just a little under 120/80 is great.
