The answer is…
No, you don’t know the symptoms of high blood pressure 😉
But don’t worry, nobody else does, either:
❝High blood pressure usually has no warning signs or symptoms, and many people do not know they have it.
Measuring your blood pressure is the only way to know whether you have high blood pressure.❞
Source: CDC | About High Blood Pressure
And, that’s a critical thing that most people don’t know about high blood pressure—in the sense of: most people don’t know that it has no symptoms.
Which is a problem, because it means that often the first people learn about it is when they sustain some vascular injury as a result (stroke, heart attack, kidney disease, etc).
And, about that kidney disease?
- Good news: the human body can function for a fair while on a kidney that’s been reduced to a fraction of its functionality
- Bad news: that’s very bad for you and simply means you now have a second serious problem of which you’re unaware

And for what to do about it: Keeping Your Kidneys Healthy (Far More Than Just Hydration)
Most people also don’t know what high blood pressure is
Well, they know it conceptually, but not numerically—based on a US survey that found, in answer to a multiple choice question on the topic:
- 25% believed that anything under 140/90 was fine
- 18% considered 130/90 to be the threshold
- 16% thought it was 140/80
- 13% got it right, at 130/80
Read in full: Most Americans cannot identify what counts as high blood pressure
In the same survey, by the way, only 39% knew that high blood pressure has no symptoms.
However, that 130/80 threshold for high blood pressure doesn’t mean that 129/79 is fine.
120/79, for example counts as elevated blood pressure.
Rather than take up undue space here, we’ll mention that you should aim for under 120/80, and for the rest, we’ll just quickly link to…

Is Herpes Forever, & Can It Be Treated?
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.
Dr. Christine Johnston explains:
Kiss and tell?
More than half of the global population (and most adults) carry a herpes simplex virus infection, yet up to about 90% of infected people don’t know they have it, because symptoms are absent or mild.
Meet the (herpesvirus) family: the term “herpesvirus” refers to a broader viral family, but the condition commonly called herpes is mainly caused by two related viruses, known to their friends as Herpes Simplex Virus Type 1 (HSV-1) and Herpes Simplex Virus Type 2 (HSV-2).
- HSV-1 usually causes oral herpes with cold sores around your mouth
- HSV-2 more commonly causes genital herpes, although either virus can infect oral, genital, finger, or eye tissues
Here’s what happens, step by step:
- Infection: the virus enters through microscopic breaks in your skin or mucous membranes such as the mouth or genitals and hijacks cellular machinery to replicate.
- Initial symptoms: most infections produce no symptoms, but some cause fluid-filled blisters that rupture into painful lesions, and severe initial infections can trigger fever, muscle aches, and headaches.
- Immune response: your immune system tries to eliminate the virus like other viral infections, but herpes is difficult (almost impossible) to clear completely.
- Nerve cell invasion: HSV infects nearby nerve cells and travels along axons to nerve clusters called “ganglia”. HSV-1 typically establishing latency in the trigeminal ganglion in the skull and HSV-2 in the sacral ganglia near the base of the spine.
- Dormancy: in these ganglia the virus becomes dormant, shutting down replication so the immune system can’t detect or eliminate it.
- Reactivation: the virus can periodically reactivate (sometimes triggered by illness, stress, or other unknown factors) traveling back down the nerve to your skin.
Transmission can be sneakily hit-and-miss, insofar as the virus spreads through direct contact when it is actively shedding from your skin or mucous membranes, even though many infected people remain unaware of their infection, due to its oft-asymptomatic nature.
How serious is it? Usually, not very. For most people, herpes causes sores during flare-ups, but doesn’t lead to serious long-term health problems.
Can we cure it? Not as yet, but antiviral drugs such as acyclovir and valacyclovir mimic components of viral DNA and inhibit viral replication, reducing symptoms and lowering HSV-2 transmission risk by about 50%.
The good news: over time, your immune system develops stronger control over the virus, so outbreaks and viral shedding usually become less frequent.
Looking forwards: scientists continue pursuing vaccines and cures, including approaches using gene editing technologies like CRISPR, but the virus’s ability to hide in nerve cells makes eradication challenging, to say the least.

What Happens If Your GLP-1 Supply Is Temporarily Interrupted?
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 fairly well-known that if you take a GLP-1 receptor agonist drug (like Ozempic, Wegovy, Mounjaro etc) for weight loss and then stop, the weight will return.
See for example: What happens when I stop taking a drug like Ozempic or Mounjaro?
This is important to consider, as it means that starting to take a GLP-1 RA drug is something one should be prepared to then continue doing for the rest of one’s life, if one wants to keep the weight off.
There are, of course, a lot of people who go onto GLP-1 RAs with the rationale “I’ll just use this to lose the weight, and then I’ll keep the weight off with my diet and lifestyle”.
Which sounds reasonable, but because of the specific mechanisms of actions of GLP-1 RAs, it simply doesn’t work that way (indeed, there are even reasons that you may, after stopping taking GLP-1 RAs, be more disposed to put weight on than you were before you started*). So, by the best of current science (which admittedly is not amazing when it comes to this topic), it does seem that taking GLP-1 RAs is a lifetime commitment.
You can read more about this here: Discontinuation and Reinitiation of Dual-Labeled GLP-1 Receptor Agonists Among US Adults With Overweight or Obesity
*We wrote previously about how a person who has been on GLP-1 RAs may afterwards be even more inclined to put on fat than before:
❝Of the four studies that actually looked at the macros (unlike most studies), they found that on average, protein intake decreased by 17.1%. Which is a big deal!
It’s an especially big deal, because while protein’s obviously important for everyone, it’s especially important for anyone trying to lose weight, because muscle mass is a major factor in metabolic base rate—which in turn is much important for fat loss/maintenance than exercise, when it comes to how many calories we burn by simply existing.
A reasonable hypothesis, therefore, is that one of the numerous reasons people who quit GLP-1 agonists immediately put fat back on, is because they probably lost muscle mass in amongst their weight loss, meaning that their metabolic base rate will have decreased, meaning that they end up more disposed to put on fat than before.
And, that’s just a hypothesis and it’s a hypothesis based on very few studies, so it’s not something to necessarily take as any kind of definitive proof of anything, but it is to say—as the researchers of this review do loudly say—more research needs to be done into this, because this has been a major gap in research so far!❞
Read in full: Semaglutide’s Surprisingly Unexamined Effects
So, what about short-term interruptions?
We like to bring you hot-off-the-press science news, in this case, it’s so new that the paper in question hasn’t actually been published yet.
However, a press release was made at the Endocrine Society’s annual meeting—yesterday, at time of writing.
The good news: they found that GLP-1 medications like semaglutide and tirzepatide remain effective for weight loss even when access is disrupted.
The bad news: it’s not like the disruption didn’t have a negative impact, though; weight loss was also temporarily disrupted; temporary partial weight regain was a relevant factor (just, weight regained was then lost again upon continuing)
In numbers: 6,392 participants in a metabolic health program were tracked over at least one year; the program combined GLP-1 RA treatment with lifestyle changes in food, exercise, sleep, and emotional health, plus one-on-one coaching. Of those, 72.5% of participants experienced at least one GLP-1 access disruption; 11.1% had multiple. Here’s how much difference that made:
- Without access disruptions: 17% average weight loss at 12 months, 20.1% at 24 months.
- With access disruptions: 13.7% average weight loss at 12 months, 14.9% at 24 months.
- With only 1–4 treatments in 12 months: >10% average weight loss at 12 months, no data for 24 months (in all likelihood they regained the weight as is normal, but the data was not recorded so we can’t say that for sure)
While we can’t link to the paper that hasn’t been published yet, we can link to the press release: Study finds patients with interrupted GLP-1 access still achieve significant weight loss
All of which points to the idea that “some is still better than none” when it comes to drug availability, and that one probably shouldn’t become overly stressed about missing a dose (for example, due to supply problems, cost issues, bureaucratic hold-ups on a repeat prescription, that kind of thing).
Nevertheless, that doesn’t mean things will necessarily be easy, for example:
❝Now that I am no longer taking the drug, unfortunately, my weight is returning to what it used to be. It felt effortless losing weight while on the trial, but now it has gone back to feeling like a constant battle with food. I hope that, if the drug can be approved for people like me, my [doctor] will be able to prescribe the drug for me in the future.❞
~ Jan, a trial participant at UCLH
Source: Gamechanger drug for treating obesity cuts body weight by 20% ← University College London Hospitals (NHS)
Want to maximize your chances of good results?
First, you might want to make sure you’re on the best GLP-1 RA for you, and that’s probably going to change over time as new drugs are developed and rolled out.
We wrote about that here: Better Than Ozempic? ← which finds that tirzepatide is better than semaglutide, retraglutide is better than tirzepatide, and an as yet unnamed tetra-receptor agonist drug is better than retraglutide.
You can also improve your results whichever drug you’re on, by bearing in mind: 10 Mistakes To Sabotage Your Ozempic Progress
Want a more natural approach?
It is possible to get many of the effects of GLP-1 RAs without taking GLP-1RAs, by enjoying foods that increase incretin, a hormone group (the most well-known of which is GLP-1) that slows down stomach emptying, which means a gentler blood sugar curve and feeling fuller for longer. It also acts on the hypothalamus, controlling appetite via the brain too (signalling fullness and reducing hunger).
For what foods to focus on, see:

The Keratin Toothpaste That Rebuilds Enamel
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.
“When it’s gone, it’s gone” is the common belief when it comes to tooth enamel. Nevertheless, there are such things as hydroxyapatite toothpaste which is not only as pathogen-killing as fluoride, but also has the added bonus of being based on one of the main minerals our teeth are made of (hydroxyapatite is a calcium phosphate compound), so it does aid in rebuilding,
There are pros and cons to both, by the way: Fluoride Toothpaste vs Non-Fluoride Toothpaste – Which is Healthier? ← with interesting numbers on the toxicity of each!
In that comparison (we compared fluoride to hydroxyapatite) we picked the fluoride on the basis of “they both do the job equally well, and they’re both very safe, but technically everything has a toxicity level, and fluoride’s is the relatively safest of these two very safe products”.
However, that’s assuming for the general job of “keeping teeth healthy”. If your teeth need remineralizing, hydroxyapatite will better promote that.
For more details, see: Tooth Remineralization: How To Heal Your Teeth Naturally
So, what’s this about keratin?
As you may be aware, keratin is a protein that can be used to make everything from your eyelashes to the horn of a rhinoceros to the wool of a lamb. Also, less usefully, sebaceous cysts, which (despite the name) or not filled with sebum, but keratin. See: How To Get Rid Of A Sebaceous Cyst
Researchers (Dr. Sara Gamea et al.) have discovered that when combined with calcium and phosphate from saliva (or, indeed, from hydroxyapatite), keratin self-organizes into a crystal-like framework that mimics natural enamel, gradually forming a dense, mineralized barrier over tooth surfaces.
And, which will be a huge relief to many, the keratin layer blocks nerve channels responsible for pain, protects against acid erosion, and prevents further enamel loss, offering both immediate comfort and long-term defense.
You can read the paper in full here: Biomimetic Mineralization of Keratin Scaffolds for Enamel Regeneration
While it’s not on the shelves just yet (discoveries do not leap straight from laboratories to supermarkets), Dr. Gamea and her team expect that the material could appear in consumer toothpaste or dentist-applied gels (like nail varnish) within a few years.
Why a few years? Because that’s how science and industry works: a discovery is made, and while that study is peer-reviewed, the important thing then is for others to also test it and see if they get the same results. So, that’ll require teams of scientists to
beg on their hands and kneesapply for grant money (often tied to the academic year), perform the studies (which will typically take months), get their work published (they hope), and finally get a commercial interest to take it up and mass produce it, and then a distributor to distribute it, and a retailer to retail it, all with contract negotiations in between each step.So, while you’re waiting…

Ozempic Helps People Walk Further
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.
There’s often a catch-22 when it comes to exercise: it’s important for good health, and/but people with ill health usually cannot exercise much.
A recent (published today, at time of writing, the 29th of March 2025, never let it be said we don’t bring you the very most up-to-date health science!) study by Dr. Neda Rasouli et al. has shown there is a possible way through that catch-22, depending on the nature of the illness.
This study followed 792 people across 112 outpatient clinical trial sites in 20 countries in North America, Asia, and Europe, with type 2 diabetes and peripheral artery disease.
What they found
Patients taking semaglutide (specifically, 1mg Ozempic) enjoyed a 21% median increase in walking distance, as well as some bonus benefits, namely:
- Weight reduction: the semaglutide group saw a greater reduction in body weight (–4.1 kg; P < 0 .0001)
- HbA1c levels: semaglutide lowered HbA1c by 1 percentage point (P < 0.0001)
- Blood pressure: systolic blood pressure decreased by 3.2 mmHg (P = 0.0042)
You may be wondering what that “P =” means: it’s the probability of this occurring by random chance, on a scale from zero (impossible outcome) to 1 (unavoidable outcome).
For example:
“We hypothesized that singing the happy birthday song before tossing a coin would result in it landing on heads. We sang the happy birthday song and tossed the coin; it landed on heads (P = 0.5)”
In science, generally speaking anything with a probability of under 0.05 (expressed as: “P < 0.05”) is considered a statistically significant result.
All this to say, the cited figures of, for example, P < 0.0001, are very significant indeed.
On which note, that 21% median increase in walking distance? P < 0.0004.
As for side effects? Serious adverse events related to the drug occurred in 1% of the semaglutide group vs 2% in the placebo group. So, that seems quite safe indeed.

How to Eat (And Still Lose Weight) – by Dr. Andrew Jenkinson

You may be wondering: what diet is he recommending?
The answer is: some guiding principles aside…. He’s not recommending a diet, per se.
What this book does instead is outline why we eat too much ← link is to where we previously had this author as a spotlight featured expert on this topic! Check it out!
He goes into a lot more detail than we ever could have in our little article, though, and this book is one of those where the reader may feel as though we have had a few classes at medical school. The style, however, is very comprehensible and accessible; there’s no obfuscating jargon here.
Once we understand the signalling that goes on in terms of hunger/satiety, and the signalling that goes on in terms of fat storage/metabolism, we can simply choose to not give our bodies the wrong signals. Yes, it’s really that simple. It feels quite like a cheat code!
Bottom line: if you’d like a better understanding of what regulates our body’s “set point” in weight/adiposity, and what can change it (for better or for worse), then this is the book for you.

Brown Rice vs Russet Potatoes – 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 brown rice to russet potatoes, we picked the rice.
Why?
First we’ll note: for brevity and to avoid undue repetitiveness, we’re henceforth going to just say “rice” and “potato”, respectively, but values and conclusions are still for brown rice and russet potatoes. Also, we are including the flesh and skin into the metrics for the potato (without the skin, many nutrients are no longer present).
In terms of macros, the rice has more fiber, carbs, and protein. It’s difficult to compare glycemic indices in this case, because they both need cooking before eating, and how one cooks them (and whether one cools them) along with other preparatory methods will change the GI considerably. Thus, we’ll simply go with the more nutritionally dense option, and that’s the rice.
In the category of vitamins, the rice has much more of vitamins B1, B2, B3, B5, B6, B7, B9, E, and choline, while the potato has more of vitamins C and K. A clear win for rice (and by the way, that’s 60x the vitamin E, but as potatoes don’t have much vitamin E, in practical terms, it’s actually the B-vitamins where rice’s strengths really show, as potatoes aren’t a bad source but rice is amazing).
When it comes to minerals, rice has a lot more copper, iron, magnesium, manganese, phosphorus, selenium, and zinc, while potato has more calcium and potassium. Another easy win for rice.
You may be wondering about phytic acid: brown rice contains this by default, and it is something of an antinutrient (i.e., if left as-is, it reduces the bioavailability of other nutrients), and/but the phytic acid content is reduced to negligible by two things: soaking and heating (especially if those two things are combined) ← doing this the way described results in bioavailability of nutrients that’s even better than if there were just no phytic acid, albeit it requires you having the time to soak, and do so at temperature.
All in all, adding up the sections makes for an overall win for brown rice, but by all means enjoy either or both; diversity is good!
