What you need to know
- COVID-19 wastewater levels are currently low, but a recent group of variants called FLiRT is making headlines.
- KP.2 is one of several FLiRT variants, and early lab tests suggest that it’s more infectious than JN.1.
- Getting infected with any COVID-19 variant can cause severe illness, heart problems, and death.
KP.2, a new COVID-19 variant, is now dominant in the United States. Lab tests suggest that it may be more infectious than JN.1, the variant that was dominant earlier this year.
Fortunately, there’s good news: Current wastewater data shows that COVID-19 infection rates are low. Still, experts are closely watching KP.2 to see if it will lead to an uptick in infections.
Read on to learn more about KP.2 and how to stay informed about COVID-19 cases in your area.
Where can I find data on COVID-19 cases in my area?
Hospitals are no longer required to report COVID-19 hospital admissions or hospital capacity to the Department of Health and Human Services. However, wastewater-based epidemiology (WBE) estimates the number of COVID-19 infections in a community based on the amount of COVID-19 viral particles detected in local wastewater.
View this map of wastewater data from the CDC to visualize COVID-19 infection rates throughout the U.S., or look up COVID-19 wastewater trends in your state.
What do we know so far about the new variant?
Early lab tests suggest that KP.2—one of a group of emerging variants called FLiRT—is similar to the previously dominant variant, JN.1, but it may be more infectious. If you had JN.1, you may still get reinfected with KP.2, especially if it’s been several months or longer since your last COVID-19 infection.
A CDC spokesperson said they have no reason to believe that KP.2 causes more severe illness than other variants. Experts are closely watching KP.2 to see if it will lead to an uptick in COVID-19 cases.
How can I protect myself from COVID-19 variants?
Staying up to date on COVID-19 vaccines reduces your risk of severe illness, long COVID, heart problems, and death. The CDC recommends that people 65 and older and immunocompromised people receive an additional dose of the updated COVID-19 vaccine this spring.
Wearing a high-quality, well-fitting mask reduces your risk of contracting COVID-19 and spreading it to others. At indoor gatherings, improving ventilation by opening doors and windows, using high-efficiency particulate air (HEPA) filters, and building your own Corsi-Rosenthal box can also reduce the spread of COVID-19.

The Truth About Statins – by Barbara H. Roberts, M.D.
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.
All too often, doctors looking to dispense a “quick fix” will prescribe from their playbook of a dozen or so “this will get you out of my office” drugs. Most commonly, things that treat symptoms rather than the cause. Sometimes, this can be fine! For example, in some cases, painkillers and antidepressants can make a big improvement to people’s lives. What about statins, though?
Prescribed to lower cholesterol, they broadly do exactly that. However…
Dr. Roberts wants us to know that we could be missing the big picture of heart health, and making a potentially fatal mistake.
This is not to say that the book argues that statins are necessarily terrible, or that they don’t have their place. Just, we need to understand what they will and won’t do, and make an informed choice.
To which end, she does advise regards when statins can help the most, and when they may not help at all. She also covers the questions to ask if your doctor wants to prescribe them. And—all so frequently overlooked—the important differences between men’s and women’s heart health, and the implications these have for the efficacy (or not) of statins.
With regard to the “alternatives to cholesterol-lowering drugs” promised in the subtitle… we won’t keep any secrets here:
Dr. Roberts (uncontroversially) recommends the Mediterranean diet. She also provides two weeks’ worth of recipes for such, in the final part of the book.
All in all, an important book to read if you or a loved one are taking, or thinking of taking, statins.

Almond Butter vs Cashew Butter – 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 almond butter to cashew butter, we picked the almond.
Why?
They’re both good! But, our inherent pro-almond bias notwithstanding, the almond butter does have a slightly better spread of nutrients.
In terms of macros, almond butter has more protein while cashew butter has more carbs, and of their fats, they’re broadly healthy in both cases, but almond butter does have less saturated fat.
In the category of vitamins, both are good sources of vitamin E, but almond butter has about 4x more. The rest of the vitamins they both contain aren’t too dissimilar, aside from some different weightings of various different B-vitamins, that pretty much balance out across the two nut butters. The only noteworthy point in cashew butter’s favor here is that it is a good source of vitamin K, which almond butter doesn’t have.
When it comes to minerals, both are good sources of lots of minerals, but most significantly, almond butter has a lot more calcium and quite a bit more potassium. In contrast, cashew butter has more selenium.
In short, they’re both great, but almond butter has more relative points in its favor than cashew butter.
Here are the two we depicted today, by the way, in case you’d like to try them:

Black Coffee vs Orange Juice – 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 black coffee to orange juice, we picked the coffee.
Why?
While this one isn’t a very like-for-like choice, it’s a choice often made, so it bears examining.
In favor of the orange juice, it has vitamins A and C and the mineral potassium, while the coffee contains no vitamins or minerals beyond trace amounts.
However, to offset that: drinking juice is one of the worst ways to consume sugar; the fruit has not only been stripped of its fiber, but also is in its most readily absorbable state (liquid), meaning that this is going to cause a blood sugar spike, which if done often can lead to insulin resistance, type 2 diabetes, non-alcoholic fatty liver disease, and more. Now, the occasional glass of orange juice (and resultant blood sugar spike) isn’t going to cause disease by itself, but everything we consume tips the scales of our health towards wellness or illness (or sometimes both, in different ways), and in this case, juice has a rather major downside that ought not be ignored.
In favor of the coffee, it has a lot of beneficial phytochemicals (mostly antioxidant polyphenols of various kinds), with no drawbacks worth mentioning unless you have a pre-existing condition of some kind.
Coffee can of course be caffeinated or decaffeinated, and we didn’t specify which here. Caffeine has some pros and cons that at worst, balance each other out, and whether or not it’s caffeinated, there’s nothing in coffee to offset the beneficial qualities of the antioxidants we mentioned before.
Obviously, in either case we are assuming consuming in moderation.
In short:
- orange juice has negatives that at least equal, if not outweigh, its positives
- coffee‘s benefits outweigh any drawbacks for most people

Make Your Negativity Work For You
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 Right Balance?
We’ve written before about positivity the pitfalls and perils of toxic positivity:
How To Get Your Brain On A More Positive Track (Without Toxic Positivity)
…as well as the benefits that can be found from selectively opting out of complaining:
A Bone To Pick… Up And Then Put Back Where We Found It
So… What place, if any, does negativity usefully have in our lives?
Carrot and Stick
We tend to think of “carrot and stick” motivation being extrinsic, i.e. there is some authority figure offering is reward and/or punishment, in response to our reactions.
In those cases when it really is extrinsic, the “stick” can still work for most people, by the way! At least in the short term.
Because in the long term, people are more likely to rebel against a “stick” that they consider unjust, and/or enter a state of learned helplessness, per “I’ll never be good enough to satisfy this person” and give up trying to please them.
But what about when you have your own carrot and stick? What about when it comes to, for example, your own management of your own healthy practices?
Here it becomes a little different—and more effective. We’ll get to that, but first, bear with us for a touch more about extrinsic motivation, because here be science:
We will generally be swayed more easily by negative feelings than positive ones.
For example, a study was conducted as part of a blood donation drive, and:
- Group A was told that their donation could save a life
- Group B was told that their donation could prevent a death
The negative wording given to group B boosted donations severalfold:
Read the paper: Life or Death Decisions: Framing the Call for Help
We have, by the way, noticed a similar trend—when it comes to subject lines in our newsletters. We continually change things up to see if trends change (and also to avoid becoming boring), but as a rule, the response we get from subscribers is typically greater when a subject line is phrased negatively, e.g. “how to avoid this bad thing” rather than “how to have this good thing”.
How we can all apply this as individuals?
When we want to make a health change (or keep up a healthy practice we already have)…
- it’s good to note the benefits of that change/practice!
- it’s even better to note the negative consequences of not doing it
For example, if you want to overcome an addiction, you will do better for your self-reminders to be about the bad consequences of using, more than the good consequences of abstinence.
See also: How To Reduce Or Quit Alcohol
This goes even just for things like diet and exercise! Things like diet and exercise can seem much more low-stakes than substance abuse, but at the end of the day, they can add healthy years onto our lives, or take them off.
Because of this, it’s good to take time to remember, when you don’t feel like exercising or do feel like ordering that triple cheeseburger with fries, the bad outcomes that you are planning to avoid with good diet and exercise.
Imagine yourself going in for that quadruple bypass surgery, asking yourself whether the unhealthy lifestyle was worth it. Double down on the emotions; imagine your loved ones grieving your premature death.
Oof, that was hard-hitting
It was, but it’s effective—if you choose to do it. We’re not the boss of you! Either way, we’ll continue to send the same good health advice and tips and research and whatnot every day, with the same (usually!) cheery tone.
One last thing…
While it’s good to note the negative, in order to avoid the things that lead to it, it’s not so good to dwell on the negative.
So if you get caught in negative thought spirals or the like, it’s still good to get yourself out of those.
If you need a little help with that sometimes, check out these:

Women are less likely to receive CPR than men. Training on manikins with breasts could help
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 someone’s heart suddenly stops beating, they may only have minutes to live. Doing CPR (cardiopulmonary resusciation) can increase their chances of survival. CPR makes sure blood keeps pumping, providing oxygen to the brain and vital organs until specialist treatment arrives.
But research shows bystanders are less likely to intervene to perform CPR when that person is a woman. A recent Australian study analysed 4,491 cardiac arrests between 2017–19 and found bystanders were more likely to give CPR to men (74%) than women (65%).
Could this partly be because CPR training dummies (known as manikins) don’t have breasts? Our new research looked at manikins available worldwide to train people in performing CPR and found 95% are flat-chested.
Anatomically, breasts don’t change CPR technique. But they may influence whether people attempt it – and hesitation in these crucial moments could mean the difference between life and death.
Pixel-Shot/Shutterstock Heart health disparities
Cardiovascular diseases – including heart disease, stroke and cardiac arrest – are the leading cause of death for women across the world.
But if a woman has a cardiac arrest outside hospital (meaning her heart stops pumping properly), she is 10% less likely to receive CPR than a man. Women are also less likely to survive CPR and more likely to have brain damage following cardiac arrests.
Bystanders are less likely to intervene if a woman needs CPR, compared to a man. doublelee/Shutterstock These are just some of many unequal health outcomes women experience, along with transgender and non-binary people. Compared to men, their symptoms are more likely to be dismissed or misdiagnosed, or it may take longer for them to receive a diagnosis.
Bystander reluctance
There is also increasing evidence women are less likely to receive CPR compared to men.
This may be partly due to bystander concerns they’ll be accused of sexual harassment, worry they might cause damage (in some cases based on a perception women are more “frail”) and discomfort about touching a woman’s breast.
Bystanders may also have trouble recognising a woman is experiencing a cardiac arrest.
Even in simulations of scenarios, researchers have found those who intervened were less likely to remove a woman’s clothing to prepare for resuscitation, compared to men. And women were less likely to receive CPR or defibrillation (an electric charge to restart the heart) – even when the training was an online game that didn’t involve touching anyone.
There is evidence that how people act in resuscitation training scenarios mirrors what they do in real emergencies. This means it’s vital to train people to recognise a cardiac arrest and be prepared to intervene, across genders and body types.
Skewed to male bodies
Most CPR training resources feature male bodies, or don’t specify a sex. If the bodies don’t have breasts, it implies a male default.
For example, a 2022 study looking at CPR training across North, Central and South America, found most manikins available were white (88%), male (94%) and lean (99%).
It’s extremely rare for a manikin to have breasts or a larger body. M Isolation photo/Shutterstock These studies reflect what we see in our own work, training other health practitioners to do CPR. We have noticed all the manikins available to for training are flat-chested. One of us (Rebecca) found it difficult to find any training manikins with breasts.
A single manikin with breasts
Our new research investigated what CPR manikins are available and how diverse they are. We identified 20 CPR manikins on the global market in 2023. Manikins are usually a torso with a head and no arms.
Of the 20 available, five (25%) were sold as “female” – but only one of these had breasts. That means 95% of available CPR training manikins were flat-chested.
We also looked at other features of diversity, including skin tone and larger bodies. We found 65% had more than one skin tone available, but just one was a larger size body. More research is needed on how these aspects affect bystanders in giving CPR.
Breasts don’t change CPR technique
CPR technique doesn’t change when someone has breasts. The barriers are cultural. And while you might feel uncomfortable, starting CPR as soon as possible could save a life.
Signs someone might need CPR include not breathing properly or at all, or not responding to you.
To perform effective CPR, you should:
- put the heel of your hand on the middle of their chest
- put your other hand on the top of the first hand, and interlock fingers (keep your arms straight)
- press down hard, to a depth of about 5cm before releasing
- push the chest at a rate of 100-120 beats per minute (you can sing a song) in your head to help keep time!)
https://www.youtube.com/embed/Plse2FOkV4Q?wmode=transparent&start=94 An example of how to do CPR – with a flat-chested manikin.
What about a defibrillator?
You don’t need to remove someone’s bra to perform CPR. But you may need to if a defibrillator is required.
A defibrillator is a device that applies an electric charge to restore the heartbeat. A bra with an underwire could cause a slight burn to the skin when the debrillator’s pads apply the electric charge. But if you can’t remove the bra, don’t let it delay care.
What should change?
Our research highlights the need for a range of CPR training manikins with breasts, as well as different body sizes.
Training resources need to better prepare people to intervene and perform CPR on people with breasts. We also need greater education about women’s risk of getting and dying from heart-related diseases.

Vit D + Calcium: Too Much Of A Good Thing?
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.
Vit D + Calcium: Too Much Of A Good Thing?
- Myth: you can’t get too much calcium!
- Myth: you must get as much vitamin D as possible!
Let’s tackle calcium first:
❝Calcium is good for you! You need more calcium for your bones! Be careful you don’t get calcium-deficient!❞
Contingently, those comments seem reasonable. Contingently on you not already having the right amount of calcium. Most people know what happens in the case of too little calcium: brittle bones, osteoporosis, and so forth.
But what about too much?
Hypercalcemia
Having too much calcium—or “hypercalcemia”— can lead to problems with…
- Groans: gastrointestinal pain, nausea, and vomiting. Peptic ulcer disease and pancreatitis.
- Bones: bone-related pains. Osteoporosis, osteomalacia, arthritis and pathological fractures.
- Stones: kidney stones causing pain.
- Moans: refers to fatigue and malaise.
- Thrones: polyuria, polydipsia, and constipation
- Psychic overtones: lethargy, confusion, depression, and memory loss.
(mnemonic courtesy of Sadiq et al, 2022)
What causes this, and how do we avoid it? Is it just dietary?
It’s mostly not dietary!
Overconsumption of calcium is certainly possible, but not common unless one has an extreme diet and/or over-supplementation. However…
Too much vitamin D
Again with “too much of a good thing”! While keeping good levels of vitamin D is, obviously, good, overdoing it (including commonly prescribed super-therapeutic doses of vitamin D) can lead to hypercalcemia.
This happens because vitamin D triggers calcium absorption into the gut, and acts as gatekeeper to the bloodstream.
Normally, the body only absorbs 10–20% of the calcium we consume, and that’s all well and good. But with overly high vitamin D levels, the other 80–90% can be waved on through, and that is very much Not Good™.
See for yourself:
- Hypercalcemia of Malignancy: An Update on Pathogenesis and Management
- Vitamin D-Mediated Hypercalcemia: Mechanisms, Diagnosis, and Treatment
How much is too much?
The United States’ Office of Dietary Supplements defines 4000 IU (100μg) as a high daily dose of vitamin D, and recommends 600 IU (15μg) as a daily dose, or 800 IU (20μg) if aged over 70.
