Krill Oil vs Fish Oil – 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 krill oil to fish oil, we picked the krill oil.
Why?
Both of these products are good sources of omega-3 fatty acids EPA and DHA, and for the specific brand depicted above, in both cases 2 softgels will give you the recommended daily amount (which is generally held to be 250–500mg combined omega-3s per day).
This brand’s fish oil gives more (640mg combined omega-3s per 2 softgels, to the same brand’s krill oil’s 480mg per 2 softgels), but since the krill oil is already in the high end of RDA territory, the excess beyond the RDA is not helpful, and not a huge factor. More quantity is not always better, when the body can only process so much at a time.
However, the krill oil gives some extra things that the fish oil doesn’t:
- Astaxanthin, a “super-antioxidant”
- and neuroprotectant, heart-healthy phospholipids
Additional considerations
We have declared “the winner” based on health considerations only. That’s a sticking point for us in all our writings; we’ll occasionally look at and mention other factors, but we know that health is what you’re here for, so that’s what we’ll always treat as most critical.
However, in case these factors may interest you and/or influence you to one or the other:
• The fish oil is about 30% cheaper financially
• The krill oil is a lot more sustainable environmentally

The Sleep Solution – by Dr. Chris Winter
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.
This book’s blurb contains a bold claim:
❝If you want to fix your sleep problems, Internet tips and tricks aren’t going to do it for you. You need to really understand what’s going on with your sleep—both what your problems are and how to solve them.❞
So, how well does it deliver, on the strength of being a whole book rather than an Internet article?
Well, for sure we wouldn’t have the room to include all the information that Dr. Winter does, in one of our main feature articles here (we’d need to spread it out over several weeks, at least).
He examines very thoroughly what is going on with sleep, sleep disturbance, and sleep deprivation. What’s going on with the different phases of sleep (far more than your phone’s sleep app will), and how imbalances in these can cause problems.
While the usual sleep hygiene tips do get a mention, he broadly assumes we know that part already. Instead, he focuses on aligning as many components as possible of our rich and interesting circadian rhythm. Yes, even if that means clawing our way out of insomnia and/or a bad sleep schedule (or lack of coherent sleep schedule) first. He gives plenty of practical advice on how to do that.
Bottom line: if you’d like to more deeply understand sleep, what is or isn’t wrong with yours, and how you can fix it, this book is a great resource.

Prostate Health: What You Should Know

Prostate Health: What You Should Know
We’re aware that very many of our readers are women, who do not have a prostate.
However, dear reader: if you do have one, and/or love someone who has one, this is a good thing to know about.
The prostate gland is a (hopefully) walnut-sized gland (it actually looks a bit like a walnut too), that usually sits just under the bladder.
See also: How to Locate Your Prostate*
*The scale is not great in these diagrams, but they’ll get the job done. Besides, everyone is different on the inside, anyway. Not in a “special unique snowflake” way, but in a “you’d be surprised how much people’s insides move around” way.
Fun fact: did you ever feel like your intestines are squirming? That’s because they are.
You can’t feel it most of the time due to the paucity of that kind of nervous sensation down there, but the peristaltic motion that they use to move food along them on the inside, also causes them push against the rest of your guts, on the outside of them. This is the exact same way that many snakes move about.
If someone has to perform an operation in that region, sometimes it will be necessary to hang the intestines on a special rack, to keep them in one place for the surgery.
What can go wrong?
There are two very common things that can go wrong with the prostate:
- Benign Prostate Hyperplasia (BPH), otherwise known as an enlarged prostate
- Prostate cancer
For most men, the prostate gland continues to grow with age, which is how the former comes about so frequently.
For everyone, due to the nature of the mathematics involved in cellular mutation and replication, we will eventually get cancer if something else doesn’t kill us first.
- Prostate cancer affects 12% of men overall, and 60% of men aged 60+, with that percentage climbing each year thereafter.
- Prostate cancer can look like BPH in the early stages (and/or, an enlarged prostate can turn cancerous) so it’s important to not shrug off the symptoms of BPH.
How can BPH be avoided/managed?
There are prescription medications that can help reduce the size of the prostate, including testosterone blockers (such as spironolactone and bicalutamide) and 5α-reductase inhibitors, such as finasteride. Each have their pros and cons:
- Testosterone-blockers are the heavy-hitters, and work very well… but have more potential adverse side effects (your body is used to running on testosterone, after all)
- 5α-reductase inhibitors aren’t as powerful, but they block the conversion of free testosterone to dihydrogen testosterone (DHT), and it’s primarily DHT that causes the problems. By blocking the conversion of T to DHT, you may actually end up with higher serum testosterone levels, but fewer ill-effects. Exact results will vary depending on your personal physiology, and what else you are taking, though.
There are also supplements that can help, including saw palmetto and pumpkin seed oil. Here’s a good paper that covers both:
We have recommended saw palmetto before for a variety of uses, including against BPH:
Too much or too little testosterone? This one supplement may fix that
You might want to avoid certain medications that can worsen BPH symptoms (but not actually the size of the prostate itself). They include:
- Antihistamines
- Decongestants
- Non-steroidal anti-inflammatory drugs (NSAIDs)
- Tricyclic antidepressants (most modern antidepressants aren’t this kind; ask your pharmacist/doctor if unsure)
You also might want to reduce/skip:
- Alcohol
- Caffeine
In all the above cases, it’s because of how they affect the bladder, not the prostate, but given their neighborliness, each thing affects the other.
What if it’s cancer? How do I know and what do I do?
The creator of the Prostate Specific Antigen (PSA) test has since decried it as “a profit-driven health disaster” that is “no better than a coin toss”, but it remains the first go-to of many medical services.
However, there’s a newer, much more accurate test, called the Prostate Screening Episwitch (PSE) test, which is 94% accurate, so you might consider asking your healthcare provider whether that’s an option:
The new prostate cancer blood test with 94 per cent accuracy
As for where to go from there, we’re out of space for today, but we previously reviewed a very good book about this, Dr. Patrick Walsh’s Guide to Surviving Prostate Cancer, and we highly recommend it—it could easily be a literal lifesaver.

Bird Flu Is Bad for Poultry and Dairy Cows. It’s Not a Dire Threat for Most of Us — Yet.
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.
Headlines are flying after the Department of Agriculture confirmed that the H5N1 bird flu virus has infected dairy cows around the country. Tests have detected the virus among cattle in nine states, mainly in Texas and New Mexico, and most recently in Colorado, said Nirav Shah, principal deputy director at the Centers for Disease Control and Prevention, at a May 1 event held by the Council on Foreign Relations.
A menagerie of other animals have been infected by H5N1, and at least one person in Texas. But what scientists fear most is if the virus were to spread efficiently from person to person. That hasn’t happened and might not. Shah said the CDC considers the H5N1 outbreak “a low risk to the general public at this time.”
Viruses evolve and outbreaks can shift quickly. “As with any major outbreak, this is moving at the speed of a bullet train,” Shah said. “What we’ll be talking about is a snapshot of that fast-moving train.” What he means is that what’s known about the H5N1 bird flu today will undoubtedly change.
With that in mind, KFF Health News explains what you need to know now.
Q: Who gets the bird flu?
Mainly birds. Over the past few years, however, the H5N1 bird flu virus has increasingly jumped from birds into mammals around the world. The growing list of more than 50 species includes seals, goats, skunks, cats, and wild bush dogs at a zoo in the United Kingdom. At least 24,000 sea lions died in outbreaks of H5N1 bird flu in South America last year.
What makes the current outbreak in cattle unusual is that it’s spreading rapidly from cow to cow, whereas the other cases — except for the sea lion infections — appear limited. Researchers know this because genetic sequences of the H5N1 viruses drawn from cattle this year were nearly identical to one another.
The cattle outbreak is also concerning because the country has been caught off guard. Researchers examining the virus’s genomes suggest it originally spilled over from birds into cows late last year in Texas, and has since spread among many more cows than have been tested. “Our analyses show this has been circulating in cows for four months or so, under our noses,” said Michael Worobey, an evolutionary biologist at the University of Arizona in Tucson.
Q: Is this the start of the next pandemic?
Not yet. But it’s a thought worth considering because a bird flu pandemic would be a nightmare. More than half of people infected by older strains of H5N1 bird flu viruses from 2003 to 2016 died. Even if death rates turn out to be less severe for the H5N1 strain currently circulating in cattle, repercussions could involve loads of sick people and hospitals too overwhelmed to handle other medical emergencies.
Although at least one person has been infected with H5N1 this year, the virus can’t lead to a pandemic in its current state. To achieve that horrible status, a pathogen needs to sicken many people on multiple continents. And to do that, the H5N1 virus would need to infect a ton of people. That won’t happen through occasional spillovers of the virus from farm animals into people. Rather, the virus must acquire mutations for it to spread from person to person, like the seasonal flu, as a respiratory infection transmitted largely through the air as people cough, sneeze, and breathe. As we learned in the depths of covid-19, airborne viruses are hard to stop.
That hasn’t happened yet. However, H5N1 viruses now have plenty of chances to evolve as they replicate within thousands of cows. Like all viruses, they mutate as they replicate, and mutations that improve the virus’s survival are passed to the next generation. And because cows are mammals, the viruses could be getting better at thriving within cells that are closer to ours than birds’.
The evolution of a pandemic-ready bird flu virus could be aided by a sort of superpower possessed by many viruses. Namely, they sometimes swap their genes with other strains in a process called reassortment. In a study published in 2009, Worobey and other researchers traced the origin of the H1N1 “swine flu” pandemic to events in which different viruses causing the swine flu, bird flu, and human flu mixed and matched their genes within pigs that they were simultaneously infecting. Pigs need not be involved this time around, Worobey warned.
Q: Will a pandemic start if a person drinks virus-contaminated milk?
Not yet. Cow’s milk, as well as powdered milk and infant formula, sold in stores is considered safe because the law requires all milk sold commercially to be pasteurized. That process of heating milk at high temperatures kills bacteria, viruses, and other teeny organisms. Tests have identified fragments of H5N1 viruses in milk from grocery stores but confirm that the virus bits are dead and, therefore, harmless.
Unpasteurized “raw” milk, however, has been shown to contain living H5N1 viruses, which is why the FDA and other health authorities strongly advise people not to drink it. Doing so could cause a person to become seriously ill or worse. But even then, a pandemic is unlikely to be sparked because the virus — in its current form — does not spread efficiently from person to person, as the seasonal flu does.
Q: What should be done?
A lot! Because of a lack of surveillance, the U.S. Department of Agriculture and other agencies have allowed the H5N1 bird flu to spread under the radar in cattle. To get a handle on the situation, the USDA recently ordered all lactating dairy cattle to be tested before farmers move them to other states, and the outcomes of the tests to be reported.
But just as restricting covid tests to international travelers in early 2020 allowed the coronavirus to spread undetected, testing only cows that move across state lines would miss plenty of cases.
Such limited testing won’t reveal how the virus is spreading among cattle — information desperately needed so farmers can stop it. A leading hypothesis is that viruses are being transferred from one cow to the next through the machines used to milk them.
To boost testing, Fred Gingrich, executive director of a nonprofit organization for farm veterinarians, the American Association of Bovine Practitioners, said the government should offer funds to cattle farmers who report cases so that they have an incentive to test. Barring that, he said, reporting just adds reputational damage atop financial loss.
“These outbreaks have a significant economic impact,” Gingrich said. “Farmers lose about 20% of their milk production in an outbreak because animals quit eating, produce less milk, and some of that milk is abnormal and then can’t be sold.”
The government has made the H5N1 tests free for farmers, Gingrich added, but they haven’t budgeted money for veterinarians who must sample the cows, transport samples, and file paperwork. “Tests are the least expensive part,” he said.
If testing on farms remains elusive, evolutionary virologists can still learn a lot by analyzing genomic sequences from H5N1 viruses sampled from cattle. The differences between sequences tell a story about where and when the current outbreak began, the path it travels, and whether the viruses are acquiring mutations that pose a threat to people. Yet this vital research has been hampered by the USDA’s slow and incomplete posting of genetic data, Worobey said.
The government should also help poultry farmers prevent H5N1 outbreaks since those kill many birds and pose a constant threat of spillover, said Maurice Pitesky, an avian disease specialist at the University of California-Davis.
Waterfowl like ducks and geese are the usual sources of outbreaks on poultry farms, and researchers can detect their proximity using remote sensing and other technologies. By zeroing in on zones of potential spillover, farmers can target their attention. That can mean routine surveillance to detect early signs of infections in poultry, using water cannons to shoo away migrating flocks, relocating farm animals, or temporarily ushering them into barns. “We should be spending on prevention,” Pitesky said.
Q: OK it’s not a pandemic, but what could happen to people who get this year’s H5N1 bird flu?
No one really knows. Only one person in Texas has been diagnosed with the disease this year, in April. This person worked closely with dairy cows, and had a mild case with an eye infection. The CDC found out about them because of its surveillance process. Clinics are supposed to alert state health departments when they diagnose farmworkers with the flu, using tests that detect influenza viruses, broadly. State health departments then confirm the test, and if it’s positive, they send a person’s sample to a CDC laboratory, where it is checked for the H5N1 virus, specifically. “Thus far we have received 23,” Shah said. “All but one of those was negative.”
State health department officials are also monitoring around 150 people, he said, who have spent time around cattle. They’re checking in with these farmworkers via phone calls, text messages, or in-person visits to see if they develop symptoms. And if that happens, they’ll be tested.
Another way to assess farmworkers would be to check their blood for antibodies against the H5N1 bird flu virus; a positive result would indicate they might have been unknowingly infected. But Shah said health officials are not yet doing this work.
“The fact that we’re four months in and haven’t done this isn’t a good sign,” Worobey said. “I’m not super worried about a pandemic at the moment, but we should start acting like we don’t want it to happen.”

DVT Risk Management Beyond The Socks
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 Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I know I am at higher risk of DVT after having hip surgery, any advice beside compression stockings?❞
First of all, a swift and easy recovery to you!
Surgery indeed increases the risk of deep vein thrombosis (henceforth: DVT), and hip or knee surgery especially so, for obvious reasons.
There are other risk factors you can’t control, like genetics (family history of DVT as an indicator) and age, but there are some that you can, including:
- smoking (so, ideally don’t; do speak to your doctor before quitting though, in case withdrawal might be temporarily worse for you than smoking)
- obesity (so, losing weight is good if overweight, but if this is going to happen, it’ll mostly happen in the kitchen not the gym, which may be a relief as you’re probably not the very most up for exercise at present)
- See also: Lose Weight, But Healthily
- sedentariness (so, while you’re probably not running marathons right now, please do try to keep moving, even if only gently)
Beyond that, yes compression socks, but also frequent gentle massage can help a lot to avoid clots forming.
Also, no surprises, a healthy diet will help, especially one that’s good for general heart health. Check out for example the Mediterranean DASH diet:
Four Ways To Upgrade The Mediterranean Diet
Also, obviously, speak with your doctor/pharmacist if you haven’t already about possible medications, including checking whether any of your current medications increase the risk and could be swapped for something that doesn’t.
Take care!

How To Build a Body That Lasts – by Adam Richardson
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.
This book is written on a premise, and that premise is: “your age doesn’t define your mobility; your mobility defines your age”.
To this end, we are treated to 328 pages of why and how to improve our mobility (mostly how; just enough on the “why” to keep the motivation flowing).
Importantly, Richardson doesn’t expect that every reader is a regular gym-bunny or about to become one, doesn’t expect you to have several times your bodyweight in iron to life at home, and doesn’t expect that you’ll be doing the vertical splits against a wall any time soon.
Rather, he expects that we’d like to not dislocate a shoulder while putting the groceries away, would like to not slip a disk while being greeted by the neighbor’s dog, and would like to not need a 7-step plan for putting our socks on.
What follows is a guide to “on the good end of normal” mobility that is sustainable for life. The idea is that you might not be winning Olympic gymnastics gold medals in your 90s, but you will be able to get in and out of a car door as comfortably as you did when you were 20, for example.
Bottom line: if you want to be a superathlete, then you might need something more than this book; if you want to be on the healthy end of average when it comes to mobility, and maintain that for the rest of your life, then this is the book for you.

Kumquat vs Persimmon – 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 kumquat to persimmon, we picked the kumquat.
Why?
In terms of macros, kumquats have more protein, though like most fruits, it’s unlike anybody’s eating them for the protein content. More importantly, they have a lot more fiber, for less than half the carbs. It bears mentioning though that (again, like most fruits) persimmon isn’t bad for this either, and both fruits are low glycemic index foods.
When it comes to vitamins, it’s not close: kumquats have more of vitamins A, B1, B2, B3, B5, B6, B9, E, and choline, while persimmon has more vitamin C. It’s worth noting that kumquats are already a very good source of vitamin C though; persimmon just has more.
In the category of minerals, kumquats again lead with more calcium, copper, magnesium, manganese, and zinc, while persimmon has more iron, phosphorus, and potassium.
In short, enjoy both, and/or whatever fruit you enjoy the most, but if looking for nutritional density, kumquats are bringing it.
