Beetroot For More Than Just Your Blood Pressure
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.
Beetroot is well-known for being good for blood pressure, but what else can it do?
Firstly, blood pressure, yes
This is because… Well, we’ll quote from a paper:
❝As a source of nitrate, beetroot ingestion provides a natural means of increasing in vivo nitric oxide (NO) availability and has emerged as a potential strategy to prevent and manage pathologies associated with diminished NO bioavailability, notably hypertension and endothelial function❞
Source: The Potential Benefits of Red Beetroot Supplementation in Health and Disease
That’s a little modest in its wording though, so let’s just be clear, it does work:
- The effects of dietary nitrate on blood pressure and endothelial function: a review of human intervention studies
- Clinical evidence demonstrating the utility of inorganic nitrate in cardiovascular health
- Vascular effects of dietary nitrate (as found in green leafy vegetables and beetroot) via the nitrate-nitrite-nitric oxide pathway
…where you can see that it significantly reduced systolic and diastolic blood pressure.
Note: this does mean that if you suffer conversely from hypotension (dangerously low blood pressure) you should probably skip the beetroot.
For your blood sugar levels, too
The fiber in whole beetroot or powdered beetroot extract (but not beetroot juice) is, as usual, good for balancing blood sugars. However, in the case of beetroot, it (probably because of the betalain content, specifically betanin) also improves insulin sensitivity, resulting in lower fasting and postprandial (after-dinner) insulin levels:
See also (cited in the above paper): Post-prandial effect of beetroot (beta vulgaris) juice on glucose and lipids levels of apparently healthy subjects
For your blood lipids, also
This one has less readily available research to support it, so in the category of “papers that aren’t paywalled into oblivion”, here’s one that concludes with the entertainingly specific:
❝Results: Beetroot juice intake increased plasma high density lipoprotein (t= -60.88, P<0.05). Triglyceride, total cholesterol, and low density lipoprotein were reduced (P<0.05). Compared with placebo, beetroot juice reduced the concentrations of triglyceride, total cholesterol, and low density lipoprotein (P<0.05).
Conclusion: Regular beetroot juice intake has significant effects on lipid profile in female soccer players, hence its suggestion for preventing diseases such as hypercholesterolemia and hypertension in female soccer players.❞
However, even if you are not a female soccer player, chances are it will have the same effect on your physiology as theirs (but, credit where it’s due, it’s right that they make claims about only what they know for sure).
Here’s the paper: Efficacy of Beetroot Juice Consumption on the Lipid Profile of Female Soccer Players
What’s good for your blood, is good for your brain
…and that’s just as true here:
When reading that, you’ll see that as well as two health outcome benefits (antidiabetic and anti-Alzheimer’s), there are also two mechanisms of action, which are:
- The blood sugar lowering, insulin sensitivity increasing, lipid improving, qualities we discussed already
- Its fabulous flavonoid content
These two things each in turn have a lot of other components and nuances, so here’s an infographic covering them ← this flowchart makes it all a lot clearer
On which note, those flavonoids aren’t the only active compounds present that result in…
Antioxidant & anti-inflammatory action
This one’s pretty straightforward, but it’s worth mentioning also that (as is commonly the case) what fights oxidation also fights cancer:
❝In recent years, the beetroot, especially the betalains (betanin) and nitrates it contains, now has received increasing attention for their effective biological activity.
Betalains have been proven to eliminate oxidative and nitrative stress by scavenging DPPH, preventing DNA damage, and reducing LDL.
It also has been found to exert antitumor activity by inhibiting cell proliferation, angiogenesis, inducing cell apoptosis, and autophagy.❞
Want to try some?
We don’t sell it, but you can easily grow your own or find it at your local supermarket; if you prefer it in supplement form, dried is better than juice (for a multitude of reasons), so here for your convenience is an example product on Amazon 😎
Enjoy!

The Cluttered Mind – by Deborah McKenna
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.
Coming from an eclectic psychotherapy background, Deborah McKenna outlines a wide array of techniques to “do what it says on the tin”, that is:
Organizing the junk drawer of your mind.
McKenna argues that it’s natural for something so gargantuan as our mind to get cluttered… but that it’s perfectly possible, with a good system, to tidy up considerably.
The benefit of this is much like the benefit of tidying a room:
Imagine a kitchen in which half the things have not been put away; there are dishes in the sink, something is growing behind the trash can… and you have a vague suspicion that if you open a certain cupboard, its contents are going to come falling out on your head. How are you going to cook a meal here?
Imagine a mind when many thoughts have been left untended; there are things you needed to process, and there’s a steady resentment of something growing in some dark part of your mind… and there’s some part of your memory that you’re afraid to even look at it, because of all it’ll cause to come surging back at you. How are you going to strategize your life here?
Fortunately, McKenna is here to guide you through doing for your mind what Marie Kondo would do for your home. And, even better, McKenna does it with a simple and clear writing style, assorted diagrams, and a step-by-step approach to getting everything in order.

Bird flu has been detected in a pig in the US. Why does that matter?
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.
The United States Department of Agriculture last week reported that a pig on a backyard farm in Oregon was infected with bird flu.
As the bird flu situation has evolved, we’ve heard about the A/H5N1 strain of the virus infecting a range of animals, including a variety of birds, wild animals and dairy cattle.
Fortunately, we haven’t seen any sustained spread between humans at this stage. But the detection of the virus in a pig marks a worrying development in the trajectory of this virus.
David MG/Shutterstock How did we get here?
The most concerning type of bird flu currently circulating is clade 2.3.4.4b of A/H5N1, a strain of influenza A.
Since 2020, A/H5N1 2.3.4.4b has spread to a vast range of birds, wild animals and farm animals that have never been infected with bird flu before.
While Europe is a hotspot for A/H5N1, attention is currently focused on the US. Dairy cattle were infected for the first time in 2024, with more than 400 herds affected across at least 14 US states.
Bird flu has enormous impacts on farming and commercial food production, because infected poultry flocks have to be culled, and infected cows can result in contaminated diary products. That said, pasteurisation should make milk safe to drink.
While farmers have suffered major losses due to H5N1 bird flu, it also has the potential to mutate to cause a human pandemic.
Birds and humans have different types of receptors in their respiratory tract that flu viruses attach to, like a lock (receptors) and key (virus). The attachment of the virus allows it to invade a cell and the body and cause illness. Avian flu viruses are adapted to birds, and spread easily among birds, but not in humans.
So far, human cases have mainly occurred in people who have been in close contact with infected farm animals or birds. In the US, most have been farm workers.
The concern is that the virus will mutate and adapt to humans. One of the key steps for this to happen would be a shift in the virus’ affinity from the bird receptors to those found in the human respiratory tract. In other words, if the virus’ “key” mutated to better fit with the human “lock”.
A recent study of a sample of A/H5N1 2.3.4.4b from an infected human had worrying findings, identifying mutations in the virus with the potential to increase transmission between human hosts.
Why are pigs a problem?
A human pandemic strain of influenza can arise in several ways. One involves close contact between humans and animals infected with their own specific flu viruses, creating opportunities for genetic mixing between avian and human viruses.
Pigs are the ideal genetic mixing vessel to generate a human pandemic influenza strain, because they have receptors in their respiratory tracts which both avian and human flu viruses can bind to.
This means pigs can be infected with a bird flu virus and a human flu virus at the same time. These viruses can exchange genetic material to mutate and become easily transmissible in humans.
The Conversation, CC BY-SA Interestingly, in the past pigs were less susceptible to A/H5N1 viruses. However, the virus has recently mutated to infect pigs more readily.
In the recent case in Oregon, A/H5N1 was detected in a pig on a non-commercial farm after an outbreak occurred among the poultry housed on the same farm. This strain of A/H5N1 was from wild birds, not the one that is widespread in US dairy cows.
The infection of a pig is a warning. If the virus enters commercial piggeries, it would create a far greater level of risk of a pandemic, especially as the US goes into winter, when human seasonal flu starts to rise.
How can we mitigate the risk?
Surveillance is key to early detection of a possible pandemic. This includes comprehensive testing and reporting of infections in birds and animals, alongside financial compensation and support measures for farmers to encourage timely reporting.
Strengthening global influenza surveillance is crucial, as unusual spikes in pneumonia and severe respiratory illnesses could signal a human pandemic. Our EPIWATCH system looks for early warnings of such activity, which can speed up vaccine development.
If a cluster of human cases occurs, and influenza A is detected, further testing (called subtyping) is essential to ascertain whether it’s a seasonal strain, an avian strain from a spillover event, or a novel pandemic strain.
Early identification can prevent a pandemic. Any delay in identifying an emerging pandemic strain enables the virus to spread widely across international borders.
Australia’s first human case of A/H5N1 occurred in a child who acquired the infection while travelling in India, and was hospitalised with illness in March 2024. At the time, testing revealed Influenza A (which could be seasonal flu or avian flu), but subtyping to identify A/H5N1 was delayed.
This kind of delay can be costly if a human-transmissible A/H5N1 arises and is assumed to be seasonal flu because the test is positive for influenza A. Only about 5% of tests positive for influenza A are subtyped further in Australia and most countries.
In light of the current situation, there should be a low threshold for subtyping influenza A strains in humans. Rapid tests which can distinguish between seasonal and H5 influenza A are emerging, and should form part of governments’ pandemic preparedness.
A higher risk than ever before
The US Centers for Disease Control and Prevention states that the current risk posed by H5N1 to the general public remains low.
But with H5N1 now able to infect pigs, and showing worrying mutations for human adaptation, the level of risk has increased. Given the virus is so widespread in animals and birds, the statistical probability of a pandemic arising is higher than ever before.
The good news is, we are better prepared for an influenza pandemic than other pandemics, because vaccines can be made in the same way as seasonal flu vaccines. As soon as the genome of a pandemic influenza virus is known, the vaccines can be updated to match it.
Partially matched vaccines are already available, and some countries such as Finland are vaccinating high-risk farm workers.

Getting Things Done – by David Allen
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 “to-do” lists are usually hopelessly tangled:
“To do thing x needs thing y doing first but that can only be done with information that I must get by doing thing z”, and so on.
Suddenly that two-minute task is looking like half an hour, which is making our overall to-do list look gargantuan. Tackling tiny parts of tasks seems useless; tackling large tasks seems overwhelming. What a headache!
Getting Things Done (“GTD”, to its friends) shows us how to gather all our to-dos, and then use the quickest ways to break down a task (in reality, often a mini-project) into its constituent parts and which things can be done next, and what order to do them in (or defer, or delegate, or ditch).
In a nutshell: The GTD system aims to make all your tasks comprehensible and manageable, for stress-free productivity. No need to strategize everything every time; you have a system now, and always know where to begin.
And by popular accounts, it delivers—many put this book in the “life-changing” category.

To Err Is Human; To Forgive, Healthy
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.
How To Forgive (And Why)
There’s an old saying that holding onto a grudge is like drinking poison and expecting the other person to die. If only it were so simple and easy as just choosing to let go!
But it’s not, is it?
When people have wronged us and/or wronged our loved ones, it’s hard to forgive, especially if they have not changed. For that matter, it can be hard to forgive ourselves for mistakes that we made, too.
Either way, “drinking that poison” can be close to literal, in terms of what harboring such anger and resentment can do for our cortisol levels.
So, what to do about it?
If you have a dialogue with the person, our previous article on communication may help a lot.
If you don’t, there are various other angles that can be taken:
The Unsent Letter
You can even send it, if you like, but it’s not the point here. The idea is to write to the person, expressing your grievances. But, (as per the above-linked article on communication) try to focus at least as much on your feelings as their actions. “When you did/said x, I felt y”, etc.
This is important for helping you process your feelings. If you send the letter, it’s also important for the other person to be able to understand your feelings.
Sometimes, we feel the things we do so strongly because we don’t have an outlet for them. Pouring out our emotions in such a fashion, on the other hand, means (to labor the metaphor) they’re no longer bottled up. Even just in and of itself, that can provide us a lot of relief.
And when we the negative emotions are no longer such high pressure, it can be easier to let go of them.
Mindfulness
Following on from the above idea, a good strategy can be simply sitting and feeling everything you need to feel, noticing it without judgement, like a curious observer.
Sometimes what we need is just to be heard, and that starts with hearing ourselves.
Compassion
There’s a Buddhist exercise that involves actively feeling compassion for three people: a loved one, a stranger, and an enemy. Many people report that it’s actually harder to feel compassion for a random stranger, than an enemy. Why? Because we don’t know them; we don’t know what’s good and bad about them in our estimation.
If you’re reading this because you want to be able to gain the peace of being able to forgive someone (even if that someone is yourself), then in at least some respect right now, that person is in the “enemy” category. So how do we unpack that?
To err is human. Everybody screws up sometimes. And also, everyone has a reason (or a complex of reasons) for acting the way they do. This does not mean that those reasons excuse the behavior, but it can explain it.
You don’t get angry at a storm for soaking you through. Even if you might not understand the physics of it in the way a meteorologist might, you understand that there were things that led to that, and you were just in the wrong place at the wrong time.
So why do we get angry at someone else for wronging us? Even if we might not understand the personal background of it in the way their psychologist or therapist might, we (hopefully) understand that there were things that caused them to be the way they were, and we were just in the wrong place at the wrong time.
And ourselves? We probably know, when we made a mistake, why we made it. Maybe we were afraid, insecure, reactive, forgetful, or too focused on some other thing. Whatever it was, we did our best at the time and, apparently, our best wasn’t as good as we’d like.
If we didn’t deserve forgiveness, we wouldn’t be critical of our past selves in the first place.
And, the science is very clear that it’s important for our health for other reasons besides cortisol management, too.
And as for others? They did the best they knew how. Maybe they were afraid, insecure, reactive, forgetful, or too focused on some other thing. Same story, different character.
Remembering that can be key to “accepting the apology we never received”.
Forgiving without forgetting
Developing the ability to forgive is a useful tool for our own mental health. It doesn’t mean we must or even should make ourselves a doormat.
“I forgive you” does not have to mean a clean slate; it means remembering that the thing happened, and just not holding on to the anger/resentment associated with it.
It may be water under the bridge now, but it might have been a devastatingly destructive wave at the time, and continuing to acknowledge truth that is sensible. Just, from a position of peace now, hopefully.
Don’t Forget…

We Are Such Stuff As Fish Are Made Of
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.
Research Review: Collagen
For something that’s a very popular supplement, not many people understand what collagen is, where it comes from, or what it does.
In a nutshell:
Collagen is a kind of protein. Our bodies make it naturally, and we can also get more in our diet and/or take extra as a supplement.
Our bodies use collagen in connective tissue, skin, tendon, bone, and cartilage. It has many functions, but a broad description would be “holding things together”.
As we get older, our bodies produce less collagen. Signs of this include wrinkles, loss of skin hydration, and joint pain.
Quick test: pinch the skin on the middle of the back of one of your hands, and then watch what happens when you get low. How quickly and easily did your skin returns to its original shape?
If it was pretty much instantanous and flawless, congratulations, you have plenty of collagen (and also elastin). If you didn’t, you are probably low on both!
(they are quite similar proteins and are made from the same base “stuff”, so if you’re low on one, you’ll usually be low on both)
Quick note: A lot of research out there has been funded by beauty companies, so we had our work cut out for us today, and have highlighted where any research may be biased.
More than skin deep
While marketing for collagen is almost exclusively aimed at “reduce wrinkles and other signs of aging”, it does a lot more than that.
You remember we mentioned that many things from the bones outward are held together by collagen? We weren’t kidding…
Read: Osteoporosis, like skin ageing, is caused by collagen loss which is reversible
Taking extra collagen isn’t the only way
We can’t (yet!) completely halt the age-related loss of collagen, but we can slow it, with our lifestyle choices:
- Don’t smoke tobacco
- Drink only in moderation (or not at all)
- Avoid foods with added sugar, and high-processed foods in general
- Wear sunscreen when appropriate
Can I get collagen from food?
Yep! Just as collagen holds our bodies together, it holds the bodies of other animals together. And, just like collagen is found in most parts of our body but most plentifully in our skin and bones, that’s what to eat to get collagen from other animals, e.g:
- Chicken skin
- Fish skin
- Bone broth ← health benefits and recipes at this link!
What about vegans?
Yes, vegans are also held together by collagen! We do not, however, recommend eating their skin or boiling their bones into broth. Ethical considerations aside, cannibalism can give you CJD!
More seriously, if you’re vegan, you can’t get collagen from a plant-based diet, but you can get the stuff your body uses to make collagen. Basically, you want to make sure you get plenty of:
- Protein (beans, pulses, nuts, etc are all fine; it’s hard to go wrong with this)
- Vitamin C
- Vitamin D
- and Zinc
Just be sure to continue to remember to avoid highly-processed foods. So:
- Soy mince/chunks whose ingredients list reads: “soya”? Yes!
- The Incredible Burger or Linda McCartney’s Sausages? Sadly less healthy
Read: Advanced Glycation End Products in Foods and a Practical Guide to Their Reduction in the Diet
Meat-eaters might want to read that one too. By far the worst offenders for AGEs (Advanced Glycation End Products, which can not only cause collagen to stiffen, but also inactivate proteins responsible for collagen repair, along with doing much more serious damage to your body’s natural functions) include:
- Hot dogs
- Bacon
- Fried/roasted/grilled meats
Is it worth it as a supplement?
That depends on you, your age, and your lifestyle, but it’s generally considered safe*
*if you have a seafood allergy, be careful though, as many supplements are from fish or shellfish—you will need to find one that’s free from your allergen
Also, all collagen is animal-derived. So if you’re a vegan, decide for yourself whether this constitutes medicine and if so, whether that makes it ethically permissible to you.
With that out of the way:
What the science says on collagen supplementation
Collagen for skin
Read: Effects of collagen supplementation on skin aging (systematic review and meta-analysis)
The short version is that they selected 19 studies with over a thousand participants in total, and they found:
In the meta-analysis, a grouped analysis of studies showed favorable results of hydrolyzed collagen supplementation compared with placebo in terms of skin hydration, elasticity, and wrinkles.
The findings of improved hydration and elasticity were also confirmed in the subgroup meta-analysis.
Based on results, ingestion of hydrolyzed collagen for 90 days is effective in reducing skin aging, as it reduces wrinkles and improves skin elasticity and hydration.
Caveat: while that systematic review had no conflicts of interests, at least some of the 19 studies will have been funded by beauty companies. Here are two, so that you know what that looks like:
Funded by Quiris to investigate their own supplement, Elasten®:
A Collagen Supplement Improves Skin Hydration, Elasticity, Roughness, and Density
Funded by BioCell to investigate their own supplement, BioCell Collagen:
The Effects of Skin Aging Associated with the Use of BioCell Collagen
A note on funding bias: to be clear, the issue is not that the researchers might be corrupt (though that could happen).
The issue is more that sometimes companies will hire ten labs to do ten research studies… and then pull funding from ones whose results aren’t going the way they’d like.
So the “best” (for them) study is the one that gets published.
Here’s another systematic review—like the one at the top of this section—that found the same, with doses ranging from 2.5g–15g per day for 8 weeks or longer:
Read: Oral Collagen Supplementation: A Systematic Review of Dermatological Applications
Again, some of those studies will have been funded by beauty companies. The general weight of evidence does seem clear and favorable, though.
Collagen for bones
Here, we encountered a lot less in the way of potential bias, because this is simply marketed a lot less. Despite being arguably far more important!
We found a high quality multi-vector randomized controlled study with a sample size of 131 postmenopausal women. They had these women take 5g collagen supplement (or placebo), and studied the results over the course of a year.
They found:
- The intake of the supplement increased bone mineral density (BMD)
- Supplementation was also associated with a favorable shift in bone markers, indicating:
- increased bone formation
- reduced bone degradation
Read: Specific Collagen Peptides Improve Bone Mineral Density and Bone Markers in Postmenopausal Wome
A follow-up study with 31 of these women found that taking 5 grams of collagen daily for a total of 4 years was associated with a progressive increase in BMD.
You might be wondering if collagen also helps against osteoarthritis.
The answer is: yes, it does (at least, it significantly reduces the symptoms)
Read: Effect of collagen supplementation on osteoarthritis symptoms
In summary:
- You need collagen for health skin, bones, joints, and more
- Your body makes collagen from your food
- You can help it by getting plenty of protein, vitamins, and minerals
- You can also help it by not doing the usual Bad Things™ (smoking, drinking, eating processed foods, especially processed meats)
- You can also eat collagen directly in the form of other animals’ skin and bones
- You can also buy collagen supplements (but watch out for allergens)
Want to try collagen supplementation?
We don’t sell it (or anything else), but for your convenience…
Check it out: Hydrolyzed Collagen Peptides (the same as in most of the above studies), 90 days supply at 5g/day
We selected this one because it’s the same kind used in many of the studies, and it doesn’t contain any known allergens.
It’s bovine collagen, meaning it’s from cows, so it’s not vegan, and also some subscribers may want to abstain for religious reasons. We respect that, and/but make our recommendations based solely on the science of health and productivity.

Muir Glen Organic vs First Field Original – 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 Muir Glen Organic Ketchup to First Field Original Ketchup, we picked the First Field.
Why?
This one was a little unfair to you, as you can’t turn them around to read the ingredients here. But the point we want to share the most today is: you have to turn them around and read the ingredients! You absolutely cannot rely on appearances!
While the Muir Glen Organic may have a very “greenwashed” aesthetic going on and the word “organic” is more eye-catching than any other word on the label, it contains 4x as much sugar and 4x as much sodium.
Side-by-side, they have, per tablespoon:
First Field Original: 1g sugar, 60mg sodium
Muir Glen Organic: 4g sugar, 240mg sodiumBut what about the importance of being organic?
Well, we have one more surprise for you: the First Field ketchup is organic too, non-GMO, and contains no added concentrates either.
This isn’t an ad for First Field (by all means enjoy their products or don’t; we’re not invested), but it is a heartfelt plea to always check the backs of products and read the labels, because fronts of products can’t be relied upon at all.
I’m sure we all get caught out sometimes, but the less often, the better!
PS: we write this, of course, before seeing the results of your voting. Maybe it won’t be a “Muir Glen Organic” sweep in the polls. But either way, it’s a call to vigilance, and a “very good, carry on” to everyone who does this already
