Fiber Fueled – by Dr. Will Bulsiewicz

We generally know that for gut health we should eat fiber, but what of the balances of different sorts of fiber?
That’s one of the main things that make this book stand out—fostering diversity in our microbiome by fostering diversity in our diet. Specifically, diversity of fiber-containing foods.
The book is part “science made easy for the lay reader”, and part recipe book. The recipes come with shopping lists and a meal planner, though we would recommend to use those as a guide rather than to try to adhere perfectly to them.
In particular, this reviewer would encourage much more generous use of healthful seasonings… and less reliance on there being leftovers several days later (tasty food gets gone quickly in this house!)
As for the science, the feel of this is more like reading a science-based observational documentary with explanations, than of reading a science textbook. Studies are mentioned in passing, but not dissected in any detail, and the focus is more on getting the key learnings across.
Bottom line: if you’d like to boost not just the amount, but also the diversity, of fiber in your diet, and reap the gut-health rewards, this book is a great guide for that!

How To Escape From A Despairing Mood
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
When we are in a despairing mood, that’s when it can feel hardest to actually implement anything we know about getting out of one. That’s why sometimes, the simplest solutions are the best:
Imagination Is Key
Despairing moods occur when it’s hard to envision a better life. Imagination is the power to envision alternatives, such as new jobs, relationships, or lifestyle, but sadness can cloud our ability to imagine solutions like changing careers, moving house, or starting fresh. With enough imagination, most problems can be worked around—and new opportunities can always be found.
Importantly: we are not bound by our past or present circumstances; we have the freedom and flexibility to choose new paths. That doesn’t mean it’ll always be a walk in the park, but “this too shall pass”.
You may be thinking: “sometimes the hardship does pass, but can last many years”, and that is true. All the more reason to check if there’s a freer lane you can slip into to speed ahead. Even if there isn’t, the mere act of imagining such lanes is already respite from the hardships—and having envisioned such will make it much easier for you to recognise when opportunities for change do come along.
To foster imagination, we are advised to expose ourselves to different narratives, preparing ourselves for alternative ways of living. Thus, we can reframe life’s challenges as intellectual puzzles, urging us to rebuild creatively and find new solutions!

Sunflower Oil vs Canola 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 sunflower oil to canola oil, we picked the sunflower oil.
Why?
They’re both terrible! But canola oil is worse. Sunflower oil is marketed as being higher in polyunsaturated fats, which it is, albeit not by much.
Canola oil is very bad for the heart, and sunflower oil is only moderately bad for the heart, to the point that it can be heart-neutral if used sparingly.
As seed oils, they are both sources of vitamin E, but you’d need to drink a cup of oil to get your daily dose, so please just eat some seeds (or nuts, or fruit, or something) instead. It can even be sunflower seeds if you like! Rapeseed* itself (the seed that canola oil is made from) isn’t really sold as a foodstuff, so that one’s less of an option.
*Fun fact: if you’re N. American and wondering what this “rapeseed” is, know that most of the rest of the Anglosphere calls canola oil “rapeseed oil”, as it’s made from rapeseed, which comes from a plant called rape, whose name is unrelated to the crime of the same name, and comes from rāpa, the Latin word for turnip. Anyway, “canola” is a portmanteau of “Canadian” and “Ola” meaning oil, and is a trademark that has made its way into generic use throughout N. America, as a less alarming name.
Back to health matters: while sunflower seeds are healthy in moderation, the ultraprocessed and refined sunflower and canola oils are not.
Canola oil has also been found to be implicated in age-related cognitive decline, whereas sunflower oil has had mixed results in that regard.
In summary
Sunflower oil is relatively, and we stress relatively, healthier than canola oil. Please use a healthier oil than either if you can. Olive oil is good for most things, and if you need something with a higher smoke point (and/or less distinctive flavor), consider avocado oil, which is also very healthy and whose smoke point is even higher than the seed oils we’ve been discussing today.

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.

Tips For Avoiding/Managing Rheumatoid Arthritis
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.
Avoiding/Managing Rheumatoid Arthritis
Arthritis is the umbrella term for a cluster of joint diseases involving inflammation of the joints, hence “arthr-” (joint) “-itis” (suffix used to denote inflammation). These are mostly, but not all, autoimmune diseases, in which the body’s immune system mistakenly attacks our own joints.
Inflammatory vs Non-Inflammatory Arthritis
Arthritis is broadly divided into inflammatory arthritis and non-inflammatory arthritis.
You may be wondering: how does one get non-inflammatory inflammation of the joints?
The answer is, in “non-inflammatory” arthritis, such as osteoarthritis, the damage comes first (by general wear-and-tear) and inflammation generally follows as part of the symptoms, rather than the cause. So the name can be a little confusing. In the case of osteo- and other “non-inflammatory” forms of arthritis, you definitely still want to keep your inflammation at bay as best you can, but it’s not as absolutely critical a deal as it is for “inflammatory” forms of arthritis.
We’ll tackle the beast that is osteoarthritis another day, however.
Today we’re going to focus on…
Rheumatoid Arthritis
This is the most common of the autoimmune forms of arthritis. Some quick facts:
- It affects a little under 1% of the global population, but the older we get, the more likely it becomes
- Early onset of rheumatoid arthritis is most likely to show up around the age of 50 (but it can show up at any age)
- However, incidence (not onset) of rheumatoid arthritis peaks in the 70s age bracket
- It is 2–4 times more common in women than in men
- Approximately one third of people stop work within two years of its onset, and this increases thereafter.
Well, that sounds gloomy.
Indeed it’s not fun. There’s a lot of stiffness and aching of joints (often with swelling too), loss of joint function can be common, and then there are knock-on effects like fatigue, weakness, and loss of appetite.
Beyond that it’s an autoimmune disorder, its cause is not known, and there is no known cure.
Is there any good news?
If you don’t have rheumatoid arthritis at the present time, you can reduce your risk factors in several ways:
- Having an anti-inflammatory diet. Get plenty of fiber, greens, and berries. Fatty fish is great too, as are oily nuts. On the other side of things, high consumption of salt, sugar, alcohol, and red meat are associated with a greater risk of developing rheumatoid arthritis.
- Not smoking. Smoking is bad for pretty much everything, including your chances of developing rheumatoid arthritis.
- Not being obese. This one may be more a matter of correlation than causation, because of the dietary factors (if one eats an anti-inflammatory diet, obesity is less likely), but the association is there.
There are other risk factors that are harder to control, such as genetics, age, sex, and having a mother who smoked.
See: Genetic and environmental risk factors for rheumatoid arthritis
What if I already have rheumatoid arthritis?
If you already have rheumatoid arthritis, it becomes a matter of symptom management.
First, reduce inflammation any (reasonable) way you can. We did a main feature on this before, so we’ll just drop that again here:
Next, consider the available medications. Your doctor may or may not have discussed all of the options with you, so be aware that there are more things available than just pain relief. To talk about them all would require a whole main feature, so instead, here’s a really well-compiled list, along with explanations about each of them, up to date as of this year:
Rheumatoid Arthritis Medication List (And What They Do, And How)
Finally, consider other lifestyle adjustments to manage your symptoms. These include:
- Exercise—gently, though! You do not want to provoke a flare-up, but you do want to maintain your mobility as best you can. There’s a use-it-or-lose-it factor here. Swimming and yoga are great options, as is tai chi. You may want to avoid exercises that involve repetitive impacts to your joints, like running.
- Rest—while keeping mobility going. Get good sleep at night (this is important), but don’t make your bed your new home, or your mobility will quickly deteriorate.
- Hot & cold—both can help, and alternating them can reduce inflammation and stiffness by improving your body’s ability to respond appropriately to these stimuli rather than getting stuck in an inappropriate-response state of inflammation.
- Mobility aids—if it helps, it helps. Maybe you only need something during a flare-up, but when that’s the case, you want to be as gentle on your body as possible while keeping moving, so if crutches, handrails etc help, then by all means get them and use them.
- Go easy on the use of braces, splints, etc—these can offer short-term relief, but at a long term cost of loss of mobility. Only you can decide where to draw the line when it comes to that trade-off.

I’ve been sick. When can I start exercising again?
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.
You’ve had a cold or the flu and your symptoms have begun to subside. Your nose has stopped dripping, your cough is clearing and your head and muscles no longer ache.
You’re ready to get off the couch. But is it too early to go for a run? Here’s what to consider when getting back to exercising after illness.
Ketut Subiyanto/Pexels Exercise can boost your immune system – but not always
Exercise reduces the chance of getting respiratory infections by increasing your immune function and the ability to fight off viruses.
However, an acute bout of endurance exercise may temporarily increase your susceptibility to upper respiratory infections, such as colds and the flu, via the short-term suppression of your immune system. This is known as the “open window” theory.
A study from 2010 examined changes in trained cyclists’ immune systems up to eight hours after two-hour high-intensity cycling. It found important immune functions were suppressed, resulting in an increased rate of upper respiratory infections after the intense endurance exercise.
So, we have to be more careful after performing harder exercises than normal.
Can you exercise when you’re sick?
This depends on the severity of your symptoms and the intensity of exercise.
Mild to moderate exercise (reducing the intensity and length of workout) may be OK if your symptoms are a runny nose, nasal congestion, sneezing and minor sore throat, without a fever.
Exercise may help you feel better by opening your nasal passages and temporarily relieving nasal congestion.
If you have a runny or blocked nose and no fever, low-intensity movement such as a walk might help. Laker/Pexels However, if you try to exercise at your normal intensity when you are sick, you risk injury or more serious illness. So it’s important to listen to your body.
If your symptoms include chest congestion, a cough, upset stomach, fever, fatigue or widespread muscle aches, avoid exercising. Exercising when you have these symptoms may worsen the symptoms and prolong the recovery time.
If you’ve had the flu or another respiratory illness that caused a high fever, make sure your temperature is back to normal before getting back to exercise. Exercising raises your body temperature, so if you already have a fever, your temperature will become high quicker, which makes you sicker.
If you have COVID or other contagious illnesses, stay at home, rest and isolate yourself from others.
When you’re sick and feel weak, don’t force yourself to exercise. Focus instead on getting plenty of rest. This may actually shorten the time it takes to recover and resume your normal workout routine.
I’ve been sick for a few weeks. What has happened to my strength and fitness?
You may think taking two weeks off from training is disastrous, and worry you’ll lose the gains you’ve made in your previous workouts. But it could be just what the body needs.
It’s true that almost all training benefits are reversible to some degree. This means the physical fitness that you have built up over time can be lost without regular exercise.
To study the effects of de-training on our body functions, researchers have undertaken “bed rest” studies, where healthy volunteers spend up to 70 days in bed. They found that V̇O₂max (the maximum amount of oxygen a person can use during maximal exercise, which is a measure of aerobic fitness) declines 0.3–0.4% a day. And the higher pre-bed-rest V̇O₂max levels, the larger the declines.
In terms of skeletal muscles, upper thigh muscles become smaller by 2% after five days of bed rest, 5% at 14 days, and 12% at 35 days of bed rest.
Muscle strength declines more than muscle mass: knee extensor muscle strength gets weaker by 8% at five days, 12% at 14 days and more than 20% after around 35 days of bed rest.
This is why it feels harder to do the same exercises after resting for even five days.
In bed rest studies, participants don’t get up. But they do in real life. Olly/Pexels But in bed rest studies, physical activities are strictly limited, and even standing up from a bed is prohibited during the whole length of a study. When we’re sick in bed, we have some physical activities such as sitting on a bed, standing up and walking to the toilet. These activities could reduce the rate of decreases in our physical functions compared with study participants.
How to ease back into exercise
Start with a lower-intensity workout initially, such as going for a walk instead of a run. Your first workout back should be light so you don’t get out of breath. Go low (intensity) and go slow.
Gradually increase the volume and intensity to the previous level. It may take the same number of days or weeks you rested to get back to where you were. If you were absent from an exercise routine for two weeks, for example, it may require two weeks for your fitness to return to the same level.
If you feel exhausted after exercising, take an extra day off before working out again. A day or two off from exercising shouldn’t affect your performance very much.

Age Later – by Dr. Nir Barzilai
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Dr. Barzilai discusses why we age, why supercentenarians age more slowly, and even, why it is so often the case that supercentenarians outside of Blue Zones have poor lifestyles (their longevity is because of protective genes that mitigate the harmful effects of those poor lifestyles—the ultimate in “survivorship bias”).
He also talks not just genetics, but also epigenetics, and thus gene expression. Bearing in mind, there’s a scale of modifiability there: with current tech, we can’t easily change a bad gene… But we often can just switch it off (or at least downregulate its expression). This is where studies in supercentenarians are helpful even for those who don’t have such fortunate genes—the supercentenarian studies show us which genes we want on or off, what gene expressions to aim for, etc. Further clinical studies can then show us what lifestyle interventions (exercise, diet, nutraceuticals, etc) can do that for us.
With regard to those lifestyle interventions, he does cover many, and that’s where a lot of the practical value of the book comes from. But it’s not just “do this, do that”; understanding the reasons behind why things work the way they do is important, so as to be more likely to do it right, and also to enjoy greater adherence (we tend to do things we understand more readily than things we have just been told to do).
There are areas definitely within the author’s blind spots—for example, when talking about menopausal HRT, he discusses at great length the results of the discredited WHI study, and considers it the only study of relevance. So, this is a reminder to not believe everything said by someone who sounds confident (Dr. Barzilai’s professional background is mostly in treating diabetes).
In terms of style, it is very much narrative; somewhat pop-science, but more “this doctor wants to tell stories”. So many stories. Now, the stories all have informational value, so this isn’t padding, but it is the style, so we mention it as such. As for citations, there aren’t any, so if you want to look up the science he mentions, you’re going to need a bit of digital sleuthery to find the papers from the clues in the stories.
Bottom line: if you’re interested in the science of aging and how that has been progressing for the past decades and where we’re at, this book will give you so many jumping-off points, and is an engaging read.
