Demystifying Cholesterol

All About Cholesterol
When it comes to cholesterol, the most common lay understanding (especially under a certain age) is “it’s bad”.
A more informed view (and more common after a certain age) is “LDL cholesterol is bad; HDL cholesterol is good”.
A more nuanced view is “LDL cholesterol is established as significantly associated with (and almost certainly a causal factor of) atherosclerotic cardiovascular disease and related mortality in men; in women it is less strongly associated and may or may not be a causal factor”
You can read more about that here:
Statins: His & Hers? ← we highly recommend reading this, especially if you are a woman and/or considering/taking statins. To be clear, we’re not saying “don’t take statins!”, because they might be the right medical choice for you and we’re not your doctors. But we are saying: here’s something to at least know about and consider.
Beyond HDL & LDL
There is also VLDL cholesterol, which as you might have guessed, stands for “very low-density lipoprotein”. It has a high, unhealthy triglyceride content, and it increases atherosclerotic plaque. In other words, it hardens your arteries more quickly.
The term “hardening the arteries” is an insufficient descriptor of what’s happening though, because while yes it is hardening the arteries, it’s also narrowing them. Because minerals and detritus passing through in the blood (the latter sounds bad, but there is supposed to be detritus passing through in the blood; it’s got to get out of the body somehow, and it’s off to get filtered and excreted) get stuck in the cholesterol (which itself is a waxy substance, by the way) and before you know it, those minerals and other things have become a solid part of the interior of your artery wall, like a little plastering team came and slapped plaster on the inside of the walls, then when it hardened, slapped more plaster on, and so on. Macrophages (normally the body’s best interior clean-up team) can’t eat things much bigger than themselves, so that means they can’t tackle the build-up of plaque.
Impact on the heart
Narrower less flexible arteries means very poor circulation, which means that organs can start having problems, which obviously includes your heart itself as it is not only having to do a harder job to keep the blood circulating through the narrower blood vessels, but also, it is not immune to also being starved of oxygen and nutrients along with the rest of the body when the circulation isn’t good enough. It’s a catch 22.
What if LDL is low and someone is getting heart disease anyway?
That’s often a case of apolipoprotein B, and unlike lipoprotein A, which is bound to LDL so usually* isn’t a problem if LDL is in “safe” ranges, Apo-B can more often cause problems even when LDL is low. Neither of these are tested for in most standard cholesterol tests by the way, so you might have to ask for them.
*Some people, around 1 in 20 people, have hereditary extra risk factors for this.
What to do about it?
Well, get those lipids tests! Including asking for the LpA and Apo-B tests, especially if you have a history of heart disease in your family, or otherwise know you have a genetic risk factor.
With or without extra genetic risks, it’s good to get lipids tests done annually from 40 onwards (earlier, if you have extra risk factors).
See also: Understanding your cholesterol numbers
Wondering whether you have an increased genetic risk or not?
Genetic Testing: Health Benefits & Methods ← we think this is worth doing; it’s a “one-off test tells many useful things”. Usually done from a saliva sample, but some companies arrange a blood draw instead. Cost is usually quite affordable; do shop around, though.
Additionally, talk to your pharmacist to check whether any of your meds have contraindications or interactions you should be aware of in this regard. Pharmacists usually know contraindications/interactions stuff better than doctors, and/but unlike doctors, they don’t have social pressure on them to know everything, which means that if they’re not sure, instead of just guessing and reassuring you in a confident voice, they’ll actually check.
Lastly, shocking nobody, all the usual lifestyle medicine advice applies here, especially get plenty of moderate exercise and eat a good diet, preferably mostly if not entirely plant-based, and go easy on the saturated fat.
Note: while a vegan diet contains zero dietary cholesterol (because plants don’t make it), vegans can still get unhealthy blood lipid levels, because we are animals and—like most animals—our body is perfectly capable of making its own cholesterol (indeed, we do need some cholesterol to function), and it can make its own in the wrong balance, if for example we go too heavy on certain kinds of (yes, even some plant-based) saturated fat.
Read more: Can Saturated Fats Be Healthy? ← see for example how palm oil and coconut oil are both plant-based, and both high in saturated fat, but palm oil’s is heart-unhealthy on balance, while coconut oil’s is heart-healthy on balance (in moderation).

What you need to know about H5N1 bird flu
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.
On May 30, the Centers for Disease Control and Prevention reported that a Michigan dairy worker tested positive for H5N1 bird flu. It was the fourth person to test positive for H5N1 in the United States, following another recent case in Michigan, an April case in Texas, and an initial case in Colorado in 2022.
H5N1 bird flu has been spreading among bird species in the U.S. since 2021, killing millions of wild birds and poultry. In late March 2024, H5N1 bird flu was found in cows for the first time, causing an outbreak in dairy cows across several states.
U.S. public health officials and researchers are particularly concerned about this outbreak because the virus has infected cows and other mammals and has spread from a cow to a human for the first time.
This bird flu strain has shown to not only make wild mammals, including marine mammals and bears, very sick but to also cause high rates of death among species, says Jane Sykes, professor of small animal medicine at the University of California, Davis, School of Veterinary Medicine.
“And now that it has been found in cattle, [it] raises particular concern for spread to all the animal species, including people,” adds Sykes.
Even though the risk for human infection is low and there has never been human-to-human transmission of H5N1, there are several actions you can take to stay protected. Read on to learn more about H5N1 bird flu and the current outbreak.
What is H5N1?
H5N1 is a type of influenza virus that most commonly affects birds, causing them severe respiratory illness and death.
The H5N1 strain first emerged in China in the 1990s, and it has continued to spread around the world since then. In 1997, the virus spread from animals to humans in Hong Kong for the first time, infecting 18 people, six of whom died.
Since 2020, the H5N1 strain has caused “an unprecedented number of deaths in wild birds and poultry in many countries,” according to the World Health Organization.
Even though bird flu is rare in humans, an H5N1 infection can cause mild to severe illness and can be fatal in some cases. It can cause eye infection, upper respiratory symptoms, and pneumonia.
What do we know about the 2024 human cases of H5N1 in the U.S.?
The Michigan worker who tested positive for H5N1 in late May is a dairy worker who was exposed to infected livestock. They were the first to experience respiratory symptoms—including a cough without a fever—during the current outbreak. They were given an antiviral and the CDC says their symptoms are resolving.
The Michigan farm worker who tested positive earlier in May only experienced eye-related symptoms and has already recovered. And the dairy worker who tested positive for the virus in Texas in April only experienced eye redness as well, was treated with an antiviral medication for the flu, and is recovering.
Is H5N1 bird flu in the milk we consume?
The Food and Drug Administration has found traces of H5N1 bird flu virus in raw or unpasteurized milk. However, pasteurized milk is safe to drink.
Pasteurization, the process of heating milk to high temperatures to kill harmful bacteria (which the majority of commercially sold milk goes through), deactivates the virus. In 20 percent of pasteurized milk samples, the FDA found small, inactive (not live nor infectious) traces of the virus, but these fragments do not make pasteurized milk dangerous.
In a recent Infectious Diseases Society of America briefing, Dr. Maximo Brito, a professor at the University of Illinois College of Medicine, said that it’s important for people to avoid “drinking unpasteurized or raw milk [because] there are other diseases, not only influenza, that could be transmitted by drinking unpasteurized milk.”
What can I do to prevent bird flu?
While the risk of H5N1 infection in humans is low, people with exposure to infected animals (like farmworkers) are most at risk. But there are several actions you can take to stay protected.
One of the most important things, according to Sykes, is taking the usual precautions we’ve taken with COVID-19 and other respiratory viruses, including frequent handwashing, especially before eating.
“Handwashing and mask-wearing [are important], just as we learned from the pandemic,” Sykes adds. “And it’s not wearing a mask at all times, but thinking about high-risk situations, like when you’re indoors in a crowded environment, where transmission of respiratory viruses is much more likely to occur.”
There are other steps you can take to prevent H5N1, according to the CDC:
- Avoid direct contact with sick or dead animals, including wild birds and poultry.
- Don’t touch surfaces that may have been contaminated with animal poop, saliva, or mucus.
- Cook poultry and eggs to an internal temperature of 165 degrees Fahrenheit to kill any bacteria or virus, including H5N1. Generally, avoid eating undercooked food.
- Avoid consuming unpasteurized or raw milk or products like cheeses made with raw milk.
- Avoid eating uncooked or undercooked food.
- Poultry and livestock farmers and workers and bird flock owners should wear masks and other personal protective equipment “when in direct or close physical contact with sick birds, livestock, or other animals; carcasses; feces; litter; raw milk; or surfaces and water that might be contaminated with animal excretions from potentially or confirmed infected birds, livestock, or other animals.” (The CDC has more recommendations for this population here.)
Is there a vaccine for H5N1?
The CDC said there are two candidate H5N1 vaccines ready to be made and distributed in case the virus starts to spread from person to person, and the country is now moving forward with plans to produce millions of vaccine doses.
The FDA has approved several bird flu vaccines since 2007. The U.S. has flu vaccines in stockpile through the National Pre-Pandemic Influenza Vaccine Stockpile program, which allows for quick response as strains of the flu virus evolve.
Could this outbreak become a pandemic?
Scientists and researchers are concerned about the possibility of H5N1 spreading among people and causing a pandemic. “Right now, the risk is low, but as time goes on, the potential for mutation to cause widespread human infection increases,” says Sykes.
“I think this virus jumping into cows has shown the urgency to keep tracking [H5N1] a lot more closely now,” Peter Halfmann, research associate professor at the University of Wisconsin-Madison’s Influenza Research Institute tells PGN. “We have our eyes on surveillance now. … We’re keeping a much closer eye, so it’s not going to take us by surprise.”

Make Social Media Work For Your Mental Health
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.
Social Media, But Healthy
Social media has a bad reputation, and rightly so. It’s calculated to trick you into doomscrolling and rage-posting, and it encourages you to compare your everyday life to other people’s carefully-curated highlight reels.
Rebalancing Dopamine (Without “Dopamine Fasting”)
But it doesn’t have to be so.
Find your community
One of the biggest strengths social media has going for it is that it can, if used well, be a powerful tool for community. As for why that’s important from a health perspective, see:
How To Beat Loneliness & Isolation
Loneliness & isolation do, of course, kill people. By:
- Accidents, e.g. household fall but nobody notices for a week
- Depression and resultant decline (and perhaps even active suicidality)
- Cognitive decline from a lack of social contact
Read more:
- The Mental Health First-Aid That You’ll Hopefully Never Need
- How To Stay Alive (When You Really Don’t Want To)
- The Five Key Traits Of Healthy Aging
So, what’s “community” to you, and to what extent can you find it online? Examples might include:
- A church, or other religious community, if we be religious
- The LGBT+ community, or even just a part of it, if that fits for us
- Any mutual-support oriented, we-have-this-shared-experience community, could be anything from AA to the VA.
Find your people, and surround yourself with them. There are more than 8,000,000,000 people on this planet, you will not find all the most compatible ones with you on your street.
Grow & nurture your community
Chances are, you have a lot to contribute. Your life experiences are valuable.
Being of service to other people is strongly associated “flourishing”, per the science.
Indeed, one of the questions on the subjective wellness scale test is to ask how much one agrees with the statement “I actively contribute to the happiness and wellbeing of others”.
See: Are You Flourishing? (There’s a Scale)
So, help people, share your insights, create whatever is relevant to your community and fits your skills (it could be anything from art to tutorials to call-to-action posts or whatever works for you and your community)
As a bonus: when people notice you are there for them, they’ll probably be there for you, too. Not always, sadly, but there is undeniable strength in numbers.
Remember it’s not the boss of you
Whatever social media platform(s) you use, the companies in question will want you to use it in the way that is most profitable for them.
Usually that means creating a lot of shallow content, clicking on as many things as possible, and never logging off.
Good ways to guard against that include:
- Use the social media from a computer rather than a handheld device
- Disable “infinite scroll” in the settings, if possible
- Set a timer and stick to it
- Try to keep your interactions to only those that are relevant and kind (for the good of your own health, let alone anyone else’s)
On that latter note…
Before posting, ask “what am I trying to achieve here?” and ensure your action is aligned with your actual desires, and not just reactivity. See also:

5 Steps To Beat Overwhelm
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.
Dealing With Overwhelm
Whether we live a hectic life in general, or we usually casually take each day as it comes but sometimes several days gang up on us at once, everyone gets overwhelmed sometimes.
Today we’re going to look at how to deal with it healthily.
Step 1: Start anywhere
It’s easy to get stuck in “analysis paralysis” and not know how to tackle an unexpected large problem. An (unhealthy) alternative is to try to tackle everything at once, and end up doing nothing very well.
Even the most expert juggler will not successfully juggle 10 random things thrown unexpectedly at them.
So instead, just pick any part of the the mountain of to-dos, and start.
If you do want a little more finesse though, check out:
Procrastination, And How To Pay Off The To-Do List Debt
Step 2: Accept what you’re capable of
This one works both ways. It means being aware of your limitations yes, but also, of your actual abilities:
- Is the task ahead of you really beyond what you are capable of?
- Could you do it right now without hesitation if a loved one’s life depended on it?
- Could you do it, but there’s a price to pay (e.g. you can do it but it’ll wipe you out in some other life area)?
Work out what’s possible and acceptable to you, and make a decision. And remember, it could be that someone else could do it, but everyone has taken the “if you want something doing, give it to someone busy” approach. It’s flattering that people have such confidence in our competence, but it is also necessary to say “no” sometimes, or at least enlisting help.
Step 3: Listen to your body
…like a leader listening to an advisory council. Your perception of tiredness, pain, weakness, and all your emotions are simply messengers. Listen to the message! And then say “thank you for the information”, and proceed accordingly.
Sometimes that will be in the way the messengers seem to be hoping for!
Sometimes, however, maybe we (blessed with a weighty brain and not entirely a slave to our limbic system) know better, and know when it’s right to push through instead.
Similarly, that voice in your head? You get to decide where it goes and doesn’t. On which note…
Step 4: Be responsive, not reactive
We wrote previously on the difference between these:
A Bone To Pick… Up And Then Put Back Where We Found It
Measured responses will always be better than knee-jerk reactions, unless it is literally a case of a split-second making a difference. 99% of our problems in life are not so; usually the problem will still be there unchanged after a moment’s mindful consideration, so invest in that moment.
You’ve probably heard the saying “give me six hours to chop down a tree, and I’ll spend the first four sharpening the axe”. In this case, that can be your mind. Here’s a good starting point:
No-Frills, Evidence-Based Mindfulness
And if your mental state is already worse than that, mind racing with threats (real or perceived) and doom-laden scenarios, here’s how to get out of that negative spiral first, so that you can apply the rest of this:
Do remember to turn it on again afterwards, though
Step 5: Transcend discomfort
This is partly a callback to step 3, but it’s now coming from a place of a clear ready mind, so the territory should be looking quite different now. Nevertheless, it’s entirely possible that your clear view shows discomfort ahead.
You’re going to make a conscious decision whether or not to proceed through the discomfort (and if you’re not, then now’s the time to start calmly and measuredly looking at alternative plans; delegating, ditching, etc).
If you are going to proceed through discomfort, then it can help to frame the discomfort as simply a neutral part of the path to getting where you want. Maybe you’re going to be going way out of your comfort zone in order to deal with something, and if that’s the case, make your peace with it now, in advance.
“Certainly it hurts” / “Well, what’s the trick then?” / “The trick, William Potter, is not minding that it hurts”
(lines from a famous scene from the 1962 movie Lawrence of Arabia)
It’s ok to say to yourself (if it’s what you decide is the right thing to do) “Yep, this experience is going to suck terribly, but I’m going to do it anyway”.

Pine Bark’s Next-Level Antioxidant Properties
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.
Pine Bark’s Next-Level Antioxidant Properties
Pine bark extract has been used by the indigenous peoples of N. America for a very long time, to treat a variety of ailments.
This one falls into the category of “things from traditional medicine that eventually got investigated and their scientific worth noticed by people from outside of those cultures”.
Not all pine trees!
If you happen to have pine trees near you, be aware that without sufficient botanical knowledge, you could find yourself bark-harvesting from the wrong tree—but many species of pine do have these qualities.
Useful (for this purpose) pine trees include, but are not limited to:
- Pinus banksiana
- Pinus massoniana
- Pinus pinaster
- Pinus radiata
- Pinus resinosa
- Pinus strobus
…which is already a fair list, but there are dozens more that have not been studied, and/or found lacking in medicinal qualities, and/or just didn’t make our list here today.
What does it do & How does it work?
We sneakily put those two questions together today because it’s easiest to explain in one:
The Pinus family in general has powerful antioxidant qualities, and not just like blueberries or coffee (wonderful as those are).
Rather, it has:
- Phenolic acids: these are the polyphenols found in many plant foods rich in antioxidants. These are great, but they aren’t the exciting part here.
- Catechins: these aren’t classified as antioxidants, but they are flavonoids that do the same job in a slightly different way
- Procyanidins: another class of flavonoids, and this is where pine bark really comes into its own
And yes, as ever, “those three things that always seem to come together”, it having these antioxidant properties means it is also anti-inflammatory and anti-cancer:
…and anti-aging:
Pleiotropic Effects of French Maritime Pine Bark Extract to Promote Healthy Aging
…which does of course mean that it almost certainly fights age-related cognitive decline, though studies for that have been animal studies so far, such as:
- Pine Bark Polyphenolic Extract Attenuates Amyloid-β and Tau Misfolding in a Model System of Alzheimer’s Disease Neuropathology
- Neuroprotective and Anti-Inflammatory Effects of Pinus densiflora Bark Extract in Gerbil Hippocampus Following Transient Forebrain Ischemia
- Neuroprotective Effects of Korean Red Pine ( Pinus densiflora) Bark Extract and Its Phenolics
- Pine bark treatment decelerates plaque development and improves spatial memory in Alzheimer’s disease mice

As ever, we don’t sell it, but here’s an example product on Amazon for your convenience; we recommend shopping around though, as prices vary a lot!

Q&A with the 10almonds Team
Q: I really loved the information about macular degeneration! I was wondering if you have any other advice about looking after eye health?
A: We may well do a full feature on it sometime! Meanwhile, some top tips include:
- Eat your greens (as you know from this last Tuesday’s edition of 10almonds)!
- Exercise! Generally. We’re not talking about eye exercises here, we’re talking about exercises that will support:
- Healthy heart rate
- Healthy blood pressure
- Healthy blood oxygenation
- Healthy blood sugar levels
- Healthy blood flow in general (so keep hydrated too! There’s a reason phlebotomists ask you to be well-hydrated before they take blood)
Eye health is a good indicator for a lot of other things, and that’s because whether or not the eyes are the window to your soul, they’re definitely the window to what your blood’s like, and that affects (and is affected by) so many other things.
- On that note, don’t smoke!
- Protect your eyes physically, too. This means:
- UV-blocking sunglasses when appropriate
- Protective eye-wear when appropriate
You think safety glasses are for laboratories and construction sites, then you go and do comparable tasks in your home? Your eyes are just as damageable in your kitchen or garden as they would be in a lab or workshop.
Some bits and bobs that can help:
- Safety sunglasses! Because a thing can do two jobs (useful in the garden now the days are brightening up!)
- Pulse oximeter! Check your own heart rate, pulse strength, and blood oxygenation at home!
- Blood pressure monitor! Because it’s so important for a lot of things and you really should have one.

Okra vs Asparagus – 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 okra to asparagus, we picked the okra.
Why?
Both are great! But…
In terms of macros, okra has more fiber and carbs, making it the more nutrient dense option, for a similar glycemic index.
In the category of vitamins, okra has more of vitamins B1, B3, B6, B9, and C, while asparagus has more of vitamins B2, B5, E, K, and choline, making for a 5:5 tie, with similar margins of difference too. Thus, definitely a tie on vitamins.
When it comes to minerals, okra has more calcium, magnesium, manganese, phosphorus, potassium, and zinc, while asparagus has more copper, iron, and selenium. An easy 6:3 win for okra.
Both of these on-the-cusp-of-being-pungent vegetables have beneficial antioxidant polyphenols (especially various forms of quercetin), but okra has more.
Adding up the sections makes for an overall win for okra, but by all means enjoy either both; diversity is good!
