Q: As I am a retired nurse, I am always interested in new medical technology and new ways of diagnosing. I have recently heard of using the eyes to diagnose Alzheimer’s. When I did some research I didn’t find too much. I am thinking the information may be too new or I wasn’t on the right sites.
(this is in response to last week’s piece on lutein, eyes, and brain health)
We’d readily bet that the diagnostic criteria has to do with recording low levels of lutein in the eye (discernible by a visual examination of macular pigment optical density), and relying on the correlation between this and incidence of Alzheimer’s, but we’ve not seen it as a hard diagnostic tool as yet either—we’ll do some digging and let you know what we find! In the meantime, we note that the Journal of Alzheimer’s Disease (which may be of interest to you, if you’re not already subscribed) is onto this:

What Is Making The Ringing In Your Ears Worse?
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. Rachael Cook, an audiologist at Applied Hearing Solutions in Phoenix, Arizona, shares her professional insights into managing tinnitus.
If you’re unfamiliar with Tinnitus, it is an auditory condition characterized by a ringing, buzzing, or humming sound, and ffects nearly 10% of the population. We’ve written on Tinnitus, and how it can disrupt your life, in this article.
Key Triggers for Tinnitus
Several everyday habits can make your tinnitus louder. Caffeine and nicotine increase blood pressure, restricting blood flow to the cochlea and worsening tinnitus. Common medications, such as pain relievers, high-dose antibiotics, and antidepressants, can also exacerbate tinnitus, especially with higher or long-term dosages.
Impact of Diet and Sleep
Dietary choices significantly impact tinnitus. Alcohol and salt alter the fluid balance in the cochlea, increasing tinnitus perception. Alcohol changes blood flow patterns and neurotransmitter production, while high salt intake has similar effects. Poor sleep quality elevates stress levels, making it harder to ignore tinnitus signals. Addressing sleep disorders like sleep apnea and insomnia can help manage tinnitus symptoms.
Importance of Treating Hearing Loss
Untreated hearing loss worsens tinnitus. Nearly 90% of individuals with tinnitus have some hearing loss. Hearing aids can reduce tinnitus perception by restoring missing sounds and reducing the brain’s internal compensatory signals. Combining hearing aids with sound therapy is said to provide even greater relief.

Is Chiropractic All It’s Cracked Up To Be?
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.
Is Chiropractic All It’s Cracked Up To Be?
Yesterday, we asked you for your opinions on chiropractic medicine, and got the above-depicted, below-described set of results:
- 38% of respondents said it keeps us healthy, and everyone should do it as maintenance
- 33% of respondents said it can correct some short-term skeletal issues, but that’s all
- 16% of respondents said that it’s a dangerous pseudoscience and can cause serious harm
- 13% of respondents said that it’s mostly just a combination of placebo and endorphins
Respondents also shared personal horror stories of harm done, personal success stories of things cured, and personal “it didn’t seem to do anything for me” stories.
What does the science say?
It’s a dangerous pseudoscience and can cause harm: True or False?
False and True, respectively.
That is to say, chiropractic in its simplest form that makes the fewest claims, is not a pseudoscience. If somebody physically moves your bones around, your bones will be physically moved. If your bones were indeed misaligned, and the chiropractor is knowledgeable and competent, this will be for the better.
However, like any form of medicine, it can also cause harm; in chiropractic’s case, because it more often than not involves manipulation of the spine, this can be very serious:
❝Twenty six fatalities were published in the medical literature and many more might have remained unpublished.
The reported pathology usually was a vascular accident involving the dissection of a vertebral artery.
Conclusion: Numerous deaths have occurred after chiropractic manipulations. The risks of this treatment by far outweigh its benefit.❞
Source: Deaths after chiropractic: a review of published cases
From this, we might note two things:
- The abstract doesn’t note the initial sample size; we would rather have seen this information expressed as a percentage. Unfortunately, the full paper is not accessible, and nor are many of the papers it cites.
- Having a vertebral artery fatally dissected is nevertheless not an inviting prospect, and is certainly a very reasonable cause for concern.
It’s mostly just a combination of placebo and endorphins: True or False?
True or False, depending on what you went in for:
- If you went in for a regular maintenance clunk-and-click, then yes, you will get your clunk-and-click and feel better for it because you had a ritualized* experience and endorphins were released.
- If you went in for something that was actually wrong with your skeletal alignment, to get it corrected, and this correction was within your chiropractor’s competence, then yes, you will feel better because a genuine fault was corrected.
*this is not implying any mysticism, by the way. Rather it means simply that placebo effect is strongest when there is a ritual associated with it. In this case it means going to the place, sitting in a pleasant waiting room, being called in, removing your shoes and perhaps some other clothes, getting the full attention of a confident and assured person for a while, this sort of thing.
With regard to its use to combat specifically spinal pain (i.e., perhaps the most obvious thing to treat by chiropractic spinal manipulation), evidence is slightly in favor, but remains unclear:
❝Due to the low quality of evidence, the efficacy of chiropractic spinal manipulation compared with a placebo or no treatment remains uncertain. ❞
Source: Clinical Effectiveness and Efficacy of Chiropractic Spinal Manipulation for Spine Pain
It can correct some short-term skeletal issues, but that’s all: True or False?
Probably True.
Why “probably”? The effectiveness of chiropractic treatment for things other than short-term skeletal issues has barely been studied. From this, we may wish to keep an open mind, while also noting that it can hardly claim to be evidence-based—and it’s had hundreds of years to accumulate evidence. In all likelihood, publication bias has meant that studies that were conducted and found inconclusive or negative results were simply not published—but that’s just a hypothesis on our part.
In the case of using chiropractic to treat migraines, a very-related-but-not-skeletal issue, researchers found:
❝Pre-specified feasibility criteria were not met, but deficits were remediable. Preliminary data support a definitive trial of MCC+ for migraine.❞
Translating this: “it didn’t score as well as we hoped, but we can do better. We got some positive results, and would like to do another, bigger, better trial; please fund it”
Source: Multimodal chiropractic care for migraine: A pilot randomized controlled trial
Meanwhile, chiropractors’ claims for very unrelated things have been harshly criticized by the scientific community, for example:
Misinformation, chiropractic, and the COVID-19 pandemic
About that “short-term” aspect, one of our subscribers put it quite succinctly:
❝Often a skeletal correction is required for initial alignment but the surrounding fascia and muscles also need to be treated to mobilize the joint and release deep tissue damage surrounding the area. In combination with other therapies chiropractic support is beneficial.❞
This is, by the way, very consistent with what was said in the very clinically-dense book we reviewed yesterday, which has a chapter on the short-term benefits and limitations of chiropractic.
A truism that holds for many musculoskeletal healthcare matters, holds true here too:
❝In a battle between muscle and bone, muscle will always win❞
In other words…
Chiropractic can definitely help put misaligned bones back where they should be. However, once they’re there, if the cause of their misalignment is not treated, they will just re-misalign themselves shortly after you walking out of your session.
This is great for chiropractors, if it keeps you coming back for endless appointments, but it does little for your body beyond give you a brief respite.
So, by all means go to a chiropractor if you feel so inclined (and you do not fear accidental arterial dissection etc), but please also consider going to a physiotherapist, and potentially other medical professions depending on what seems to be wrong, to see about addressing the underlying cause.
Take care!

Luxurious Longevity Risotto
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.
Pearl barley is not only tasty and fiber-rich, but also, it contains propionic acid, which lowers cholesterol. The fiber content also lowers cholesterol too, of course, by the usual mechanism. The dish’s health benefits don’t end there, though; check out the science section at the end of the recipe!
You will need
- 2 cups pearl barley
- 3 cups sliced chestnut mushrooms
- 2 onions, finely chopped
- 6 large leaves collard greens, shredded
- ½ bulb garlic, finely chopped
- 8 spring onions, sliced
- 1½ quarts low-sodium vegetable stock
- 2 tbsp nutritional yeast
- 1 tbsp chia seeds
- 1 tbsp black pepper, coarse ground
- 1 tsp MSG or 2 tsp low-sodium salt
- 1 tsp rosemary
- 1 tsp thyme
- Extra virgin olive oil, for cooking
- Optional garnish: fresh basil leaves
Method
(we suggest you read everything at least once before doing anything)
1) Heat a little oil in a large sauté pan; add the onions and garlic and cook for 5 minutes; add the mushrooms and cook for another 5 minutes.
2) Add the pearl barley and a cup of the vegetable stock. Cook, stirring, until the liquid is nearly all absorbed, and add more stock every few minutes, as per any other risotto. You may or may not use all the stock you had ready. Pearl barley takes longer to cook than rice, so be patient—it’ll be worth the wait!
Alternative: an alternative is to use a slow cooker, adding a quart of the stock at once and coming back about 4 hours later—thus, it’ll take a lot longer, but will require minimal/no supervision.
3) When the pearl barley has softened, become pearl-like, and the dish is taking on a creamy texture, stir in the rest of the ingredients. Once the greens have softened, the dish is done, and it’s time to serve. Add the garnish if using one:
Enjoy!

Perfectionism, And How To Make Yours Work For You
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Harness The Power Of Your Perfectionism
A lot of people see perfectionism as a problem—and it can be that!
We can use perfectionism as a would-be shield against our fear of failure, by putting things off until we’re better prepared (repeat forever, or at least until the deadliniest deadline that ever deadlined), or do things but really struggle to draw a line under them and check them off as “done” because we keep tweaking and improving and improving… With diminishing returns (forever). So, that’s not helpful.
But, if we’re mindful, we can also leverage our perfectionism to our benefit.
Great! How?
First we need to be able to discern the ways in which perfectionism can be bad or good for us. Or as it’s called in psychology, ways in which our perfectionism can be maladaptive or adaptive.
- Maladaptive: describing a behavioral adaptation to our environment—specifically, a reactive behavioral adaptation that is unhealthy and really is not a solution to the problem at hand
- Adaptive: describing a behavioral adaptation to our environment—specifically, a responsive behavioral adaptation that is healthy and helps us to thrive
So in the case of perfectionism, one example for each might be:
- Maladaptive: never taking up that new hobby, because you’re just going to suck at it anyway, and what’s the point if you’re not going to excel? You’re a perfectionist, and you don’t settle for anything less than excellence.
- Adaptive: researching the new hobby, learning the basics, and recognizing that even if the results are not immediately perfect, the learning process can be… Yes, even with mistakes along the way, for they too are part of learning! You’re a perfectionist, and you’re going to be the best possible student of your new hobby.
Did you catch the key there?
When it comes to approaching things we do in life—either because we want to or because we must—there are two kinds of mindset: goal-oriented, and task-oriented.
Broadly speaking, each has their merits, and as a general topic, it’s beyond the scope of today’s main feature. Here we’re looking at it in the context of perfectionism, and in that frame, there’s a clear qualitative difference:
- The goal-oriented perfectionist will be frustrated to the point of torment, at not immediately attaining the goal. Everything short of that will be a means to an end, at best. Not fun.
- The task-oriented perfectionist will take joy in going about the task in the best way possible, and optimizing their process as they go. The journey itself will be rewarding and a tangible product of their consistent perfectionism.
The good news is: you get to choose! You’re not stuck in a box.
If you’re thinking “I’m a perfectionist and I’m generally a goal-oriented person”, that’s fine. You’re just going to need to reframe your goals.
- Instead of: my goal is to be fluent in Arabic
- …so you never speak it, because to err is human, all too human, and you’re a perfectionist, so you don’t want that!
- Let’s try: my goal is to study Arabic for at least 15 minutes per day, every day, without fail, covering at least some new material each time, no matter how small the increase
- …and then you go and throw yourself into conversation way out of your depth, make mistakes, and get corrections, because that’s how you learn, and you’re a perfectionist, so you want that!
This goes for any field of expertise, of course.
- If you want to play the violin solo in Carnegie Hall, you have to pick up your violin and practice each day.
- If you want to be a world-renowned pastry chef, you have to make a consistent habit of baking.
- If you want to write a bestselling book, you have to show up at your keyboard.
Be perfect all you want, but be the perfect student.
And as your skills grow, maybe you’ll upgrade that to also being the perfect practitioner, and perhaps later still, the perfect teacher.
But just remember:
Perfection comes not from the end goal (that would be backwards thinking!) but from the process (which includes mistakes; they’re an important part of learning; embrace them and grow!), so perfect that first.

Willpower: A Muscle To Flex, Or Spoons To Conserve?
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.
Willpower: A Muscle To Flex, Or Spoons To Conserve?
We have previously written about motivation; this one’s not about that.
Rather, it’s about willpower itself, and especially, the maintenance of such. Which prompts the question…
Is willpower something that can be built up through practice, or something that is a finite resource that can be expended?
That depends on you—and your experiences.
- Some people believe willpower is a metaphorical “muscle” that must be exercised to be built up
- Some people believe willpower is a matter of metaphorical “spoons” that can be used up
A quick note on spoon theory: this traces its roots to Christine Miserandino’s 2003 essay about chronic illness and the management of limited energy. She details how she explained this to a friend in a practical fashion, she gave her a bunch of spoons from her kitchen, as an arbitrary unit of energy currency. These spoons would then need to be used to “pay” for tasks done; soon her friend realised that if she wanted to make it through the day, she was going to have to give more forethought to how she would “spend” her spoons, or she’d run out and be helpless (and perhaps hungry and far from home) before the day’s end. So, the kind of forethought and planning that a lot of people with chronic illnesses have to give to every day’s activities.
You can read it here: But You Don’t Look Sick? The Spoon Theory
So, why do some people believe one way, and some believe the other? It comes down to our experiences of our own willpower being built or expended. Researchers (Dr. Vanda Siber et al.) studied this, and concluded:
❝The studies support the idea that what people believe about willpower depends, at least in part, on recent experiences with tasks as being energizing or draining.❞
Source: Autonomous Goal Striving Promotes a Nonlimited Theory About Willpower
In other words, there’s a difference between going out running each morning while healthy, and doing so with (for example) lupus.
On a practical level, this translates to practicable advice:
- If something requires willpower but is energizing, this is the muscle kind! Build it.
- If something requires willpower and is draining, this is the spoons kind! Conserve it.
Read the above two bullet-points as many times as necessary to cement them into your hippocampus, because they are the most important message of today’s newsletter.
Do you tend towards the “nonlimited” belief, despite getting tired? If so, here’s why…
There is something that can continue to empower us even when we get physically fatigued, and that’s the extent to which we truly get a choice about what we’re doing. In other words, that “Autonomous” at the front of the title of the previous study, isn’t just word salad.
- If we perceive ourselves as choosing to do what we are doing, with free will and autonomy (i.e., no externally created punitive consequences), we will feel much more empowered, and that goes for our willpower too.
- If we perceive ourselves as doing what we have to (or suffer the consequences), we’ll probably do it, but we’ll find it draining, and that goes for our willpower too.
Until such a time as age-related physical and mental decline truly take us, we as humans tend to gradually accumulate autonomy in our lives. We start as literal babies, then are children with all important decisions made for us, then adolescents building our own identity and ways of doing things, then young adults launching ourselves into the world of adulthood (with mixed results), to a usually more settled middle-age that still has a lot of external stressors and responsibilities, to old age, where we’ve often most things in order, and just ourselves and perhaps our partner to consider.
Consequently…
Age differences in implicit theories about willpower: why older people endorse a nonlimited theory
…which explains why the 30-year-old middle-manager might break down and burn out and stop going to work, while an octogenarian is busy training for a marathon daily before getting back to their daily book-writing session, without fail.
One final thing…
If you need a willpower boost, have a snack*. If you need to willpower boost to avoid snacking, then plan for this in advance by finding a way to keep your blood sugars stable. Because…
The physiology of willpower: linking blood glucose to self-control
*Something that will keep your blood sugars stable, not spike them. Nuts are a great example, unless you’re allergic to such, because they have a nice balance of carbohydrates, protein, and healthy fats.

Rice vs Buckwheat – 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 rice to buckwheat, we picked the buckwheat.
Why?
It’s a simple one today:
- The vitamin and mineral profiles are very similar, so neither of these are a swaying factor
- In terms of macros, rice is higher in carbohydrates while buckwheat is higher in fiber
- Buckwheat also has more protein, but not by much
- Buckwheat has the lower glycemic index, and a lower insulin index, too
While buckwheat cannot always be reasonably used as a substitute for rice (often because the texture would not work the same), in many cases it can be.
And if you love rice, well, so do we, but variety is also the spice of life indeed, not to mention important for good health. You know that whole “eat 30 different plants per week” thing? Grains count in that tally! So substituting buckwheat in place of rice sometimes seems like a very good bet.
