❝How does your diet change clean out your arteries of the bad cholesterol?❞
There’s good news and bad news here, and they can both be delivered with a one-word reply:
Slowly.
Or rather: what’s being cleaned out is mostly not the LDL (bad) cholesterol, but rather, the result of that.
When our diet is bad for cardiovascular health, our arteries get fatty deposits on their walls. Cholesterol gets stuck here too, but that’s not the main physical problem.
Our body’s natural defenses come into action and try to clean it up, but they (for example macrophages, a kind of white blood cell that consumes invaders and then dies, before being recycled by the next part of the system) often get stuck and become part of the buildup (called atheroma), which can lead to atherosclerosis and (if calcium levels are high) hardening of the arteries, which is the worst end of this.
This can then require medical attention, precisely because the body can’t remove it very well—especially if you are still maintaining a heart-unhealthy diet, thus continuing to add to the mess.
However, if it is not too bad yet, yes, a dietary change alone will reverse this process. Without new material being added to the arterial walls, the body’s continual process of rejuvenation will eventually fix it, given time (free from things making it worse) and resources.
In fact, your arteries can be one of the quickest places for your body to make something better or worse, because the blood is the means by which the body moves most things (good or bad) around the body.
All the more reason to take extra care of it, since everything else depends on it!

We created a VR tool to test brain function. It could one day help diagnose dementia
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.
If you or a loved one have noticed changes in your memory or thinking as you’ve grown older, this could reflect typical changes that occur with ageing. In some cases though, it might suggest something more, such as the onset of dementia.
The best thing to do if you have concerns is to make an appointment with your GP, who will probably run some tests. Assessment is important because if there is something more going on, early diagnosis can enable prompt access to the right interventions, supports and care.
But current methods of dementia screening have limitations, and testing can be daunting for patients.
Our research suggests virtual reality (VR) could be a useful cognitive screening tool, and mitigate some of the challenges associated with current testing methods, opening up the possibility it may one day play a role in dementia diagnosis.
Where current testing is falling short
If someone is worried about their memory and thinking, their GP might ask them to complete a series of quick tasks that check things like the ability to follow simple instructions, basic arithmetic, memory and orientation.
These sorts of screening tools are really good at confirming cognitive problems that may already be very apparent. But commonly used screening tests are not always so good at detecting early and more subtle difficulties with memory and thinking, meaning such changes could be missed until they get worse.
A clinical neuropsychological assessment is better equipped to detect early changes. This involves a comprehensive review of a patient’s personal and medical history, and detailed assessment of cognitive functions, including attention, language, memory, executive functioning, mood factors and more. However, this can be costly and the testing can take several hours.
Testing is also somewhat removed from everyday experience, not directly tapping into activities of daily living.
Enter virtual reality
VR technology uses computer-generated environments to create immersive experiences that feel like real life. While VR is often used for entertainment, it has increasingly found applications in health care, including in rehabilitation and falls prevention.
Using VR for cognitive screening is still a new area. VR-based cognitive tests generally create a scenario such as shopping at a supermarket or driving around a city to ascertain how a person would perform in these situations.
Notably, they engage various senses and cognitive processes such as sight, sound and spatial awareness in immersive ways. All this may reveal subtle impairments which can be missed by standard methods.
VR assessments are also often more engaging and enjoyable, potentially reducing anxiety for those who may feel uneasy in traditional testing environments, and improving compliance compared to standard assessments.
Most studies of VR-based cognitive tests have explored their capacity to pick up impairments in spatial memory (the ability to remember where something is located and how to get there), and the results have been promising.
Given VR’s potential for assisting with diagnosis of cognitive impairment and dementia remains largely untapped, our team developed an online computerised game (referred to as semi-immersive VR) to see how well a person can remember, recall and complete everyday tasks. In our VR game, which lasts about 20 minutes, the user role plays a waiter in a cafe and receives a score on their performance.
To assess its potential, we enlisted more than 140 people to play the game and provide feedback. The results of this research are published across three recent papers.
Testing our VR tool
In our most recently published study, we wanted to verify the accuracy and sensitivity of our VR game to assess cognitive abilities.
We compared our test to an existing screening tool (called the TICS-M) in more than 130 adults. We found our VR task was able to capture meaningful aspects of cognitive function, including recalling food items and spatial memory.
We also found younger adults performed better in the game than older adults, which echoes the pattern commonly seen in regular memory tests.
In a separate study, we followed ten adults aged over 65 while they completed the game, and interviewed them afterwards. We wanted to understand how this group – who the tool would target – perceived the task.
These seniors told us they found the game user-friendly and believed it was a promising tool for screening memory. They described the game as engaging and immersive, expressing enthusiasm to continue playing. They didn’t find the task created anxiety.
For a third study, we spoke to seven health-care professionals about the tool. Overall they gave positive feedback, and noted its dynamic approach to age-old diagnostic challenges.
However, they did flag some concerns and potential barriers to implementing this sort of tool. These included resource constraints in clinical practice (such as time and space to carry out the assessment) and whether it would be accessible for people with limited technological skills. There was also some scepticism about whether the tool would be an accurate method to assist with dementia diagnosis.
While our initial research suggests this tool could be a promising way to assess cognitive performance, this is not the same as diagnosing dementia. To improve the test’s ability to accurately detect those who likely have dementia, we’ll need to make it more specific for that purpose, and carry out further research to validate its effectiveness.
We’ll be conducting more testing of the game soon. Anyone interested in giving it a go to help with our research can register on our team’s website.

Blood-Brain Barrier Breach Blamed For Brain-Fog
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.
Move Over, Leaky Gut. Now It’s A Leaky Brain.
…which is not a headline that promises good news, and indeed, the only good news about this currently is “now we know another thing that’s happening, and thus can work towards a treatment for it”.
Back in February (most popular media outlets did not rush to publish this, as it rather goes against the narrative of “remember when COVID was a thing?” as though the numbers haven’t risen since the state of emergency was declared over), a team of Irish researchers made a discovery:
❝For the first time, we have been able to show that leaky blood vessels in the human brain, in tandem with a hyperactive immune system may be the key drivers of brain fog associated with long covid❞
~ Dr. Matthew Campbell (one of the researchers)
Let’s break that down a little, borrowing some context from the paper itself:
- the leaky blood vessels are breaching the blood-brain-barrier
- that’s a big deal, because that barrier is our only filter between our brain and Things That Definitely Should Not Go In The Brain™
- a hyperactive immune system can also be described as chronic inflammation
- in this case, that includes chronic neuroinflammation which, yes, is also a major driver of dementia
You may be wondering what COVID has to do with this, and well:
- these blood-brain-barrier breaches were very significantly associated (in lay terms: correlated, but correlated is only really used as an absolute in write-ups) with either acute COVID infection, or Long Covid.
- checking this in vitro, exposure of brain endothelial cells to serum from patients with Long Covid induced the same expression of inflammatory markers.
How important is this?
As another researcher (not to mention: professor of neurology and head of the school of medicine at Trinity) put it:
❝The findings will now likely change the landscape of how we understand and treat post-viral neurological conditions.
It also confirms that the neurological symptoms of long covid are measurable with real and demonstrable metabolic and vascular changes in the brain.❞
~ Dr. Colin Doherty (see mini-bio above)

Beyond the obvious “get protected when offered boosters/updates” (see also: The Truth About Vaccines), other good practices include the same things most people were doing when the pandemic was big news, especially avoiding enclosed densely-populated places, washing hands frequently, and looking after your immune system.

Hazelnuts vs Almonds – 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 hazelnuts to almonds, we picked the almonds.
Why?
It’s closer than you might think! But we say almonds do come out on top.
In terms of macronutrients, almonds have notably more protein, while hazelnuts have notably more fat (healthy fats, though). Almonds are also higher in both carbs and fiber. Looking at Glycemic Index, hazelnuts’ GI is low and almonds’ GI is zero. We could call the macros category a tie, but ultimately if we need to prioritize any of these things, it’s protein and fiber, so we’ll call this a nominal win for almonds.
When it comes to vitamins, hazelnuts have more of vitamins B1, B5, B6, B9 C, and K. Meanwhile, almonds have more of vitamins B2, B3, E, and choline. So, a moderate win for hazelnuts.
In the category of minerals, almonds retake the lead with more calcium, magnesium, phosphorus, potassium, selenium, and zinc, while hazelnuts boast more copper and manganese. A clear win for almonds.
Adding up the categories, this makes for a marginal win for almonds. Of course, both of these nuts are very healthy (assuming you are not allergic), and best is to enjoy both if possible.

The Obesity Code – by Dr. Jason Fung
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.
Firstly, if you have already read Dr. Fung’s other book, The Diabetes Code, which we reviewed a little while ago, you can probably skip this one. It has mostly the same information, presented with a different focus.
While The Diabetes Code assumes you are diabetic, or prediabetic, or concerned about avoiding/reversing those conditions, The Obesity Code assumes you are obese, or heading in that direction, or otherwise are concerned about avoiding/reversing obesity.
What it’s not, though, is a weight loss book. Will it help if you want to lose weight? Yes, absolutely. But there is no talk here of weight loss goals, nor any motivational coaching, nor week-by-week plans, etc.
Instead, it’s more an informative textbook. With exactly the sort of philosophy we like here at 10almonds: putting information into people’s hands, so everyone can make the best decisions for themselves, rather than blindly following someone else’s program.
Dr. Fung explains why various dieting approaches don’t work, and how we can work around such things as our genetics, as well as most external factors except for poverty. He also talks us through how to change our body’s insulin response, and get our body working more like a lean machine and less like a larder for hard times.
Bottom line: this is a no-frills explanation of why your body does what it does when it comes to fat storage, and how to make it behave differently about that.

Psychology Sunday: Family Estrangment & How To Fix It
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.
Estrangement, And How To Heal It
We’ve written before about how deleterious to the health loneliness and isolation can be, and what things can be done about it. Today, we’re tackling a related but different topic.
We recently had a request to write about…
❝Reconciliation of relationships in particular estrangement mother adult daughter❞
And, this is not only an interesting topic, but a very specific one that affects more people than is commonly realized!
In fact, a recent 800-person study found that more than 43% of people experienced family estrangement of one sort or another, and a more specific study of more than 2,000 mother-child pairs found that more than 11% of mothers were estranged from at least one adult child.
So, if you think of the ten or so houses nearest to you, probably at least one of them contains a parent estranged from at least one adult child. Maybe it’s yours. Either way, we hope this article will give you some pause for thought.
Which way around?
It makes a difference to the usefulness of this article whether any given reader experiencing estrangement is the parent or the adult child. We’re going to assume the reader is the parent. It also makes a difference who did the estranging. That’s usually the adult child.
So, we’re broadly going to write with that expectation.
Why does it happen?
When our kids are small, we as parents hold all the cards. It may not always feel that way, but we do. We control our kids’ environment, we influence their learning, we buy the food they eat and the clothes they wear. If they want to go somewhere, we probably have to take them. We can even set and enforce rules on a whim.
As they grow, so too does their independence, and it can be difficult for us as parents to relinquish control, but we’re going to have to at some point. Assuming we are good parents, we just hope we’ve prepared them well enough for the world.
Once they’ve flown the nest and are living their own adult lives, there’s an element of inversion. They used to be dependent on us; now, not only do they not need us (this is a feature not a bug! If we have been good parents, they will be strong without us, and in all likelihood one day, they’re going to have to be), but also…
We’re more likely to need them, now. Not just in the “oh if we have kids they can look after us when we’re old” sense, but in that their social lives are growing as ours are often shrinking, their family growing, while ours, well, it’s the same family but they’re the gatekeepers to that now.
If we have a good relationship, this goes fine. However, it might only take one big argument, one big transgression, or one “final straw”, when the adult child decides the parent is more trouble than they’re worth.
And, obviously, that’s going to hurt. But it’s pretty much how it pans out, according to studies:
Here be science: Tensions in the Parent and Adult Child Relationship: Links to Solidarity and Ambivalence
How to fix it, step one
First, figure out what went wrong.
Resist any urge to protect your own feelings with a defensive knee-jerk “I don’t know; I was a good, loving parent”. That’s a very natural and reasonable urge and you’re quite possibly correct, but it won’t help you here.
Something pushed them away. And, it will almost certainly have been a push factor from you, not a pull factor from whoever is in their life now. It’s easy to put the blame externally, but that won’t fix anything.
And, be honest with yourself; this isn’t a job interview where we have to present a strength dressed up as a “greatest weakness” for show.
You can start there, though! If you think “I was too loving”, then ok, how did you show that love? Could it have felt stifling to them? Controlling? Were you critical of their decisions?
It doesn’t matter who was right or wrong, or even whether or not their response was reasonable. It matters that you know what pushed them away.
How to fix it, step two
Take responsibility, and apologize. We’re going to assume that your estrangement is such that you can, at least, still get a letter to them, for example. Resist the urge to argue your case.
Here’s a very good format for an apology; please consider using this template:
The 10-step (!) apology that’s so good, you’ll want to make a note of it
You may have to do some soul-searching to find how you will avoid making the same mistake in the future, that you did in the past.
If you feel it’s something you “can’t change”, then you must decide what is more important to you. Only you can make that choice, but you cannot expect them to meet you halfway. They already made their choice. In the category of negotiation, they hold all the cards now.
How to fix it, step three
Now, just wait.
Maybe they will reply, forgiving you. If they do, celebrate!
Just be aware that once you reconnect is not the time to now get around to arguing your case from before. It will never be the time to get around to arguing your case from before. Let it go.
Nor should you try to exact any sort of apology from them for estranging you, or they will at best feel resentful, wonder if they made a mistake in reconnecting, and withdraw.
Instead, just enjoy what you have. Many people don’t get that.
If they reply with anger, maybe it will be a chance to reopen a dialogue. If so, family therapy could be an approach useful for all concerned, if they are willing. Chances are, you all have things that you’d all benefit from talking about in a calm, professional, moderated, neutral environment.
You might also benefit from a book we reviewed previously, “Parent Effectiveness Training”. This may seem like “shutting the stable door after the horse has bolted”, but in fact it’s a very good guide to relationship dynamics in general, and extensively covers relations between parents and adult children.
If they don’t reply, then, you did your part. Take solace in knowing that much.
Some final thoughts:
At the end of the day, as parents, our kids living well is (hopefully) testament to that we prepared them well for life, and sometimes, being a parent is a thankless task.
But, we (hopefully) didn’t become parents for the plaudits, after all.

Beyond Balancing The Books – by George Marino, CPA, CFP

We hear a lot about the importance of mindfulness, yet how can Zen-like non-attachment to the material world go well with actually surviving (let alone thriving) in a Capitalist society?
Books that try to connect the two often end up botching it badly to the level of early 2000s motivational posters.
So, what does this book do differently? Mostly it’s because rather than a motivational speech with exhortations to operate on a higher plain and manifest your destiny and all that, it gives practical, down-to-earth advice and offers small simple things you can do or change to mindfully engage with the world of business rather than operating on auto-pilot.
Basically: how to cut out the stress without cutting out your performance.
All in all, we think both your health and your productivity will thank you for it!
