What is HRT? HRT and Hormones Explained

In this short video, Dr. Sophie Newton explains how menopausal HRT, sometimes called just MHT, is the use of exogenous (didn’t come from your body) to replace/supplement the endogenous hormones (made in your body) that aren’t being made in the quantities that would result in ideal health.
Bioidentical hormones are, as the name suggests, chemically identical to those made in the body; there is no difference, all the way down to the atomic structure.
People are understandably wary of “putting chemicals into the body”, but in fact, everything is a chemical and those chemicals are also found in your body, just not in the numbers that we might always like.
In the case of hormones, these chemical messengers are simply there to tell cells what to do, so having the correct amount of hormones ensures that all the cells that need to get a certain message, get it.
In the case of estrogen specifically, while it’s considered a sex hormone (and it is), it’s responsible for a lot more than just the reproductive system, which is why many people without correct estrogen levels (such as peri- or post-menopause, though incorrect levels can happen earlier in life for other reasons too) can severely feel their absence in a whole stack of ways.
What ways? More than we can list here, but some are discussed in the video:

Frozen/Thawed/Refrozen Meat: How Much Is Safety, And How Much Is Taste?
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 You Can (And Can’t) Safely Do With Frozen Meat
Yesterday, we asked you:
❝You have meat in the freezer. How long is it really safe to keep it?❞
…and got a range of answers, mostly indicating to a) follow the instructions (a very safe general policy) and b) do not refreeze if thawed because that would be unsafe. Fewer respondents indicated that meat could be kept for much longer than guidelines say, or conversely, that it should only be kept for weeks or less.
So, what does the science say?
Meat can be kept indefinitely (for all intents and purposes) in a freezer; it just might get tougher: True or False?
False, assuming we are talking about a normal household electrical freezer that bottoms out at about -18℃ / 0℉.
Fun fact: cryobiologists cryopreserve tissue samples (so basically, meat) at -196℃ / -320℉, and down at those temperatures, the tissues will last a lot longer than you will (and, for all practical purposes: indefinitely). There are other complications with doing so (such as getting the sample through the glass transition point without cracking it during the vitrification process) but those are beyond the scope of this article.
If you remember back to your physics or perhaps chemistry classes at school, you’ll know that molecules move more quickly at higher temperatures, and more slowly at lower ones, only approaching true stillness as they near absolute zero (-273℃ / -459℉ / 0K ← we’re not saying it’s ok, although it is; rather, that is zero kelvin; no degree sign is used with kelvins)
That means that when food is frozen, the internal processes aren’t truly paused; it’s just slowed to a point of near imperceptibility.
So, all the way up at the relatively warm temperatures of a household freezer, a lot of processes are still going on.
What this means in practical terms: those guidelines saying “keep in the freezer for up to 4 months”, “keep in the freezer for up to 9 months”, “keep in the freezer for up to 12 months” etc are being honest with you.
More or less, anyway! They’ll usually underestimate a little to be on the safe side—but so should you.
Bad things start happening within weeks at most: True or False?
False, for all practical purposes. Again, assuming a normal and properly-working household freezer as described above.
(True, technically but misleadingly: the bad things never stopped; they just slowed down to a near imperceptible pace—again, as described above)
By “bad” here we should clarify we mean “dangerous”. One subscriber wrote:
❝Meat starts losing color and flavor after being in the freezer for too long. I keep meat in the freezer for about 2 months at the most❞
…and as a matter of taste, that’s fair enough!
It is unsafe to refreeze meat that has been thawed: True or False?
False! Assuming it has otherwise been kept chilled, just the same as for fresh meat.
Food poisoning comes from bacteria, and there is nothing about the meat previously having been frozen that will make it now have more bacteria.
That means, for example…
- if it was thawed (but chilled) for a period of time, treat it like you would any other meat that has been chilled for that period of time (so probably: use it or freeze it, unless it’s been more than a few days)
- if it was thawed (and at room temperature) for a period of time, treat it like you would any other meat that has been at room temperature for that period of time (so probably: throw it out, unless the period of time is very small indeed)
The USDA gives for 2 hours max at room temperature before considering it unsalvageable, by the way.
However! Whenever you freeze meat (or almost anything with cells, really), ice crystals will form in and between cells. How much ice crystallization occurs depends on several variables, with how much water there is present in the food is usually the biggest factor (remember that animal cells are—just like us—mostly water).
Those ice crystals will damage the cell walls, causing the food to lose structural integrity. When you thaw it out, the ice crystals will disappear but the damage will be left behind (this is what “freezer burn” is).
So if your food seems a little “squishy” after having been frozen and thawed, that’s why. It’s not rotten; it’s just been stabbed countless times on a microscopic level.
The more times you freeze and thaw and refreeze food, the more this will happen. Your food will degrade in structural integrity each time, but the safety of it won’t have changed meaningfully.

Meditation That You’ll Actually Enjoy

Meditation That You’ll Actually Enjoy
We previously wrote about…
No-Frills, Evidence-Based Mindfulness
this is a great primer, by the way, for the science and simplicity of mindfulness, along with the simplest mindfulness meditation to get you going.
Today, we’re going to have some fun with meditation.
First: The Problem
Once the usefulness and health benefits of meditation have been established, often people want to meditate, but complain they don’t have the time.
But that’s not the real reason, though, is it?
Let’s face it, a basic meditation can give benefits within two minutes. Or within two breaths, for that matter. So, it’s not really for a lack of time.
The real reason is because it doesn’t feel productive, and it’s not fun. For us to feel motivated to do a thing, usually we need at least one or the other. And even if we know it really is productive, it not feeling that way will hobble us.
So instead, let us make things a little more fun, with…
Meditation games!
As it turns out, there are good kinds of meditation with which one can have a little fun.
Catch the next thought
A common feature of many meditative practices is the experience of having fewer, or ideally no, thoughts.
But it’s hard to enact a negative, and thoughts keep coming.
So instead, make yourself comfortable, settle in, and lie in wait for thoughts. When one comes along, pounce on it in your mind. And then release it, and wait for the next.
At first, your thoughts may be coming thick and fast, but soon, you’ll find the pauses between them lengthening, and you have moments of contented not-knowing of what the next thought will be before it comes along.
This state of relaxed, ready alertness, calm and receptive, is exactly what we’re hoping to find here. But don’t worry about that while you’re busy lying in wait for the next wild thought to come along
Counting breaths
Many meditative practices involve focus on one’s breath. But it’s easy for attention to wander!
This game is a simple one. Count your breaths, not trying to change your rate of breathing at all, just letting it be, and see how high you can get before you lose count.
Breathing in and out, once, counts as one breath, by the way.
You may find that your rate of breathing naturally slows while you’re doing this. That’s fine; let it. It’ll add to the challenge of the game, because before long there will be lengthy pauses between each number.
If you lose count, just start again, and see if you can beat your high score.
This meditation game is an excellent exercise to build for sustained focus, while also improving the quality of breathing (as a side-effect of merely paying attention to it).
Hot spot, cold spot
The above two meditation games were drawn from Japanese and Chinese meditative practices, zen and qigong respectively; this one’s from an Indian meditative practice, yoga nidra. But for now, just approach it with a sense of playful curiosity, for best results.
Make yourself comfortable, lying on your back, arms by your sides.
Take a moment first to pay attention to each part of your body from head to toe, and release any tension that you may be holding along the way.
First part: mentally scan your body for where it feels warmest, or most active, or most wanting of attention (for example if there is pain, or an itch, or some other sensation); that’s your “hot spot” for the moment.
Second part: mentally scan your body for where it feels coolest, or most inert, or almost like it’s not a part of your body at all; that’s your “cold spot” for the moment.
Now, see if you can flip them. Whether you can or can’t, notice if your “hot spot” or “cold spot” moves, or if you can move them consciously.
This meditation game is a great exercise to strengthen interoception and somatic awareness in general—essential for being able to “listen to your body”!
Closing thoughts
All three practices above have very serious reasons and great benefits, but make sure you don’t skip enjoyment of the fun aspects!
Being “young at heart” is, in part, to do with the ability to enjoy—literally, to take joy in—the little things in life.
With that in mind, all we have left to say here is…
Enjoy!

Healthy Kids, Happy Kids – by Dr. Elisa Song
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 have young children or perhaps grandchildren, you probably care deeply about those children and their wellbeing, but there can often be a lot more guesswork than would be ideal, when it comes to ensuring they be and remain healthy.
Nevertheless, a lot of common treatments for children are based (whether parents know it or not—and often they dont) on what is most convenient for the parent, not necessarily what is best for the child. Dr. Song looks to correct that.
Rather than dosing kids with acetaminophen or even antibiotics, assuming eczema can be best fixed with a topical cream (treating the symptom rather than the cause, much?), and that some things like asthma “just are”, and “that’s unfortunate”, Dr. Song takes us on a tour of pediatric health, centered around the gut.
Why the gut? Well, it’s pretty central to us as adults, and it’s the same for kids, except one difference: their gut microbiome is changing even more quickly than ours (along with the rest of their body), and as such, is even more susceptible to little nudges for better or for worse, having a big impact in either direction. So, might as well make it a good one!
After an explanatory overview, most of the book is given over to recognizing and correcting what things can go wrong, including the top 25 acute childhood conditions, and the most critical chronic ones, and how to keep things on-track as a team (the child is part of the team! An important part!).
The style of the book is very direct and instructional; easy to understand throughout. It’s a lot like being in a room with a very competent pediatrician who knows her stuff and explains it well, thus neither patronizing nor mystifying.
Bottom line: if there are kids in your life, be they yours or your grandkids or someone else, this is a fine book for giving them the best foundational health.

Tight Hamstrings? Here’s A Test To Know If It’s Actually Your Sciatic Nerve
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.
Tight hamstrings are often not actually due to hamstring issues, but rather, are often being limited by the sciatic nerve. This video offers a home test to determine if the sciatic nerve is causing mobility problems (and how to improve it, if so):
The Connection
Try this test:
- Sit down with a slumped posture.
- Extend one leg with the ankle flexed.
- Note any stretching or pulling sensation behind the knee or in the calf.
- Bring your head down to your chest
If this increases the sensation, it likely indicates sciatic nerve involvement.
If only the hamstrings are tight, head movement won’t change the stretch sensation.
This is because the nervous system is a continuous structure, so head movement can affect nerve tension throughout the body. While this can cause problems, it can also be integral in the solution. Here are two ways:
- Flossing method: sit with “poor” slumped posture, extend the knee, keep the ankle flexed, and lift the head to relieve nerve tension. This movement helps the sciatic nerve slide without stretching it.
- Even easier method: lie on your back, grab behind the knee, and extend the leg while extending the neck. This position avoids compression in the gluteal area, making it suitable for severely compromised nerves. Perform the movement without significant stretching or pain.
In both cases: move gently to avoid straining the nerve, which can worsen muscle tension. Do 10 repetitions per leg, multiple times a day; after a week, increase to 20 reps.
A word of caution: speak with your doctor before trying these exercises if you have underlying neurological diseases, cut or infected nerves, or other severe conditions.

More Mediterranean – by American’s Test Kitchen
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.
Regular 10almonds readers will know that we talk about the Mediterranean diet often, and with good reason; it’s been for quite a while now the “Gold Standard” when it comes to scientific consensus on what constitutes a good diet for healthy longevity.
However, it’s easy to get stuck in a rut of cooking the same three meals and thinking “I must do something different, but not today, because I have these ingredients and don’t know what to cook” and then when one is grocery-shopping, it’s “I should have researched a new thing to cook, but since I haven’t, I’ll just get the ingredients for what I usually cook, since we need to eat”, and so the cycle continues.
This book will help break you out of that cycle! With (as the subtitle promises) hundreds of recipes, there’s no shortage of good ideas. The recipes are “plant-forward” rather than plant-based per se (i.e. there are some animal products in them), though for the vegetarians and vegans, it’s nothing that’s any challenge to substitute.
Bottom line: if you’re looking for “delicious and nutritious”, this book is sure to put a rainbow on your plate and a smile on your face.

Eat Better, Feel Better – by Giada de Laurentis
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.
In yesterday’s edition of 10almonds, we reviewed Dr. Aujla’s “The Doctor’s Kitchen“; today we’re reviewing a different book about healing through food—in this case, with a special focus on maintaining energy and good health as we get older.
De Laurentis may not be a medical doctor, but she is a TV chef, and not only holds a lot of influence, but also has access to a lot of celebrity doctors and such; that’s reflected a lot in her style and approach here.
The recipes are clear and easy to follow; well-illustrated and nicely laid-out.
This cookbook’s style is less “enjoy this hearty dish of rice and beans with these herbs and spices” and more “you can serve your steak salad with white beans and sweet shallot dressing on a bed of organic quinoa if you haven’t already had your day’s serving of grains, of course”.
It’s a little fancier, in short, and more focused on what to cut out, than what to include. On account of that, this could make it a good contrast to yesterday’s book, which had the opposite focus.
She also recommends assorted adjuvant practices; some that are evidence-based, like intermittent fasting and meditation, and some that are not, like extreme detox-dieting, and acupuncture (which has no bearing on gut health).
Bottom line: if you like the idea of eating for good health, and prefer a touch of celebrity lifestyle to your meals, this one’s a good book for you.
