Reading As A Cognitive Exercise

Reading, Better
It is relatively uncontroversial to say that reading is good for cognitive health, but we don’t like to make claims without science if we can help it, so let’s get started:
There was a 2021 study, which found that even when controlling for many other factors, including highest level of education, socioeconomic status, and generalized pre-morbid intelligence:
❝high reading activity, as defined by almost daily reading, was associated with lower odds of cognitive decline, compared to low reading activity❞
Source: Can reading increase cognitive reserve?
However, not all reading is the same. And this isn’t just about complexity or size of vocabulary, either. It’s about engagement.
And that level of engagement remains the key factor, no matter how quickly or slowly someone reads, as the brain tends to automatically adjust reading speed per complexity, because the brain’s “processing speed” remains the same:

Everyone’s “processing speed” is different (and is associated with generalized intelligence and executive functions), though as a general rule of thumb, the more we practice it, the faster our processing speed gets. So if you balked at the notion of “generalized intelligence” being a factor, be reassured that this association goes both ways.
So is the key to just read more?
That’s a great first step! But…
The key factor still remains: engagement.
So what does that mean?
It is not just the text that engages you. You must also engage the text!
This is akin to the difference between learning to drive by watching someone else do it, and learning by getting behind the wheel and having a go.
When it comes to reading, it should not be a purely passive thing. Sure, if you are reading a fiction book at bedtime, get lost in it, by all means. But when it comes to non-fiction reading, engage with it actively!
For example, I (your writer here, hi), when reading non-fiction:
- Read at what is generally considered an unusually fast pace, but
- Write so many notes in the margins of physical books, and
- Write so many notes using the “Notes” function on my Kindle
And this isn’t just like a studious student taking notes. Half the time I am…
- objecting to content (disagreeing with the author), or
- at least questioning it, or which is especially important, or
- noting down questions that came to my mind as a result of what I am reading.
This latter is a bit like:
- when you are reading 10almonds, sometimes you will follow our links and go off down a research rabbit-hole of your own, and that’s great!
- sometimes you will disagree with something and write to tell us, and that’s great too (when this happens, one or the other or all of us will learn something, and yes, we have published corrections before now)!
- sometimes what you read here will prompt a further question, and you’ll send that to us, and guess what, also great! We love questions.
Now, if your enjoyment of 10almonds is entirely passive, don’t let us stop you (we know our readers like quick-and-easy knowledge, and that’s good too), it’s just, the more you actively engage with it, the more you’ll get out of it.
This, by the way, was also a lifelong habit of Leonardo da Vinci, which you can read about here:
How to Think Like Leonardo da Vinci: Seven Steps to Genius Every Day – by Michael J. Gelb
a very good book that we reviewed last year
How you read (i.e. what medium) matters too!
Are you reading this on a desktop/laptop, or a mobile device? That difference could matter more than the difference between paper and digital, according to this study from 2020 that found…
❝The cumulation of evidence from this and previous studies suggests that reading on a tablet affords different interactions between the reader and the text than reading on a computer screen.
Reading on a tablet might be more similar to reading on paper, and this may impact the attentional processes during reading❞
What if my mind wanders easily?
You can either go with it, or train to improve focus.
Going with it: just make sure you have more engaging reading to get distracted by. It’s all good.
Training focus: this is trickier, but worthwhile, as executive function (you will remember from earlier) was an important factor too, and training focus is training executive function.
As for one way to do that…
If you’d like a primer for getting going with that, then you may enjoy our previous main feature:

Mineral-Rich Mung Bean Pancakes
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.
Mung beans are rich in an assortment of minerals, especially iron, copper, phosphorus, and magnesium. They’re also full of protein and fiber! What better way to make pancakes healthy?
You will need
- ½ cup dried green mung beans
- ½ cup chopped fresh parsley
- ½ cup chopped fresh dill
- ¼ cup uncooked wholegrain rice
- ¼ cup nutritional yeast
- 1 tsp MSG, or 2 tsp low-sodium salt
- 2 green onions, finely sliced
- 1 tbsp extra virgin olive oil
Method
(we suggest you read everything at least once before doing anything)
1) Soak the mung beans and rice together overnight.
2) Drain and rinse, and blend them in a blender with ¼ cup of water, to the consistency of regular pancake batter, adding more water (sparingly) if necessary.
3) Transfer to a bowl and add the rest of the ingredients except for the olive oil, which latter you can now heat in a skillet over a medium-high heat.
4) Add a few spoonfuls of batter to the pan, depending on how big you want the pancakes to be. Cook on both sides until you get a golden-brown crust, and repeat for the rest of the pancakes.
5) Serve! As these are savory pancakes, you might consider serving them with a little salad—tomatoes, olives, and cucumbers go especially well.
Enjoy!

Carbonated Water: For Weight Loss, Satiety, Or Just Gas?
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.
There are two main mechanisms of action by which sparkling water is considered to help satiety and/or weight loss; they are:
- It “fills us up” such that we feel fuller sooner, and thus eat less, and thus (all other things being equal) perhaps lose weight
- The carbon dioxide is absorbed into the bloodstream, where (as a matter of chemistry) it improves glucose metabolism, thus lowering blood sugars and indirectly leading (potentially) to weight loss, but even if not, lowered blood sugars are good for most people most of the time, right?
However, there are just a few problems:
Full of gas?
Many people self-report enjoying sparkling water as a way to feel fuller while fasting (or even while eating). However, the plural of “anecdote” is not “data”, so, here be data… Ish:
❝In order to determine whether such satiating effects occur through oral carbonic stimulation alone, we conducted modified sham-feeding (SF) tests (carbonated water ingestion (CW), water ingestion (W), carbonated water sham-feeding (CW-SF), and water sham-feeding (W-SF)), employing an equivalent volume and standardized temperature of carbonated and plain water, in a randomized crossover design.
Thirteen young women began fasting at 10 p.m. on the previous night and were loaded with each sample (15ºC, 250 mL) at 9 a.m. on separate days. Electrogastrography (EGG) recordings were obtained from 20 min before to 45 min after the loading to determine the power and frequency of the gastric myoelectrical activity. Appetite was assessed using visual analog scales. After ingestion, significantly increased fullness and decreased hunger ratings were observed in the CW group. After the load, transiently but significantly increased fullness as well as decreased hunger ratings were observed in the CW-SF group. The powers of normogastria (2-4 cpm) and tachygastria (4-9 cpm) showed significant increases in the CW and W groups, but not in the CW-SF and W-SF groups. The peak frequency of normogastria tended to shift toward a higher band in the CW group, whereas it shifted toward a lower band in the CW-SF group, indicating a different EGG rhythm.
Our results suggest that CO2-induced oral stimulation is solely responsible for the feeling of satiety.❞
~ Dr. Maki Suzuki et al.
Now, that’s self-reported, and a sample size of 13, so it’s not the most airtight science ever, but it is at least science. Here’s the paper, by the way:
Oral Carbonation Attenuates Feeling of Hunger and Gastric Myoelectrical Activity in Young Women
Here’s another small study with 8 people, which found that still and sparkling water had the exact same effect:
Effect of carbonated water on gastric emptying and intragastric meal distribution
However, drinking water (still or sparkling) with a meal will not have anywhere near the same effect for satiety as consuming food that has a high water-content.
See also: Some Surprising Truths About Hunger And Satiety ← our main feature in which we examine the science of volumetrics, including a study that shows how water incorporated into a food (but not served with a food) decreases caloric intake.
As an aside, one difference that carbonation can make is to increase ghrelin levels—that’s the hunger hormone (the satiety hormone is leptin, by the way). This one’s a rat study, but it seems reasonable that the same will be true of humans:
…which is worth bearing in mind even if you yourself are not, in fact, a male rat.
The glucose guzzler?
This one has simply been the case of a study being misrepresented, for example here:
Fizzy water might aid weight loss by providing a small boost to glucose uptake and metabolism
The idea is that higher levels of carbon dioxide in the blood mean faster glucose metabolism, which is technically true. Now, often “technically true” is the best kind of true, but not here, because it’s simply not useful.
In short, we produce so much carbon dioxide as part of our normal respiratory processes, that any carbon dioxide we might consume in a carbonated water is barely a blip in the graph.
Oh, and that article we just linked? Even within the article, despite running with that headline, the actual scientists quoted are saying such things as:
❝While there is a hypothetical link between carbonated water and glucose metabolism, this has yet to be tested in well-designed human intervention studies❞
~ Professor Sumantra Ray
Note: the word “hypothetical” means “one level lower than theoretical”. This is very far from being a conclusion.
And the study itself? Wasn’t even about carbonated water, it was about kidney dialysis and how the carbon dioxide content can result in hypoglycemia:
The mechanism of hypoglycemia caused by hemodialysis
…which got referenced in this paper (not a study):
Can carbonated water support weight loss?
…and even that concluded:
❝CO2 in carbonated water may promote weight loss by enhancing glucose uptake and metabolism in red blood cells.
However, the amount is so small that it is difficult to expect weight loss effects solely from the CO2 in carbonated water.
Drinking carbonated water may also affect blood glucose measurements.❞
Note: the word “may”, when used by a scientist and in the absence of any stronger claims, means “we haven’t ruled out the possibility”.
What breaking news that is.
Stop the press! No, really, stop it!
So… What does work?
There are various ways of going about actually hacking hunger (and they stack; i.e. you can use multiple methods and get cumulative results), and we wrote about them here:

Reduce Caffeine’s Impact on Kidneys
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? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
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
❝Avid coffee drinker so very interested in the results Also question Is there something that you could take or eat that would prevent the caffeine from stimulating the kidneys? I tried to drink decaf from morning to night not a good result! Thanks❞
That is a good question! The simple answer is “no” (but keep reading, because all is not lost)
There’s no way (that we yet know of) to proof the kidneys against the stimulating effect of caffeine. This is especially relevant because part of caffeine’s stimulating effect is noradrenergic, and that “ren” in the middle there? It’s about the kidneys. This is just because the adrenal gland is situated next to them (actually, it’s pretty much sitting on top of them), hence the name, but it does mean that the kidneys are about the hardest thing in the body to have not effected by caffeine.
However! The effects of caffeine in general can be softened a little with l-theanine (found in tea, or it can be taken as a supplement). It doesn’t stop it from working, but it makes the curve of the effect a little gentler, and so it can reduce some unwanted side effects.
You can read more about l-theanine here:

Bored of Lunch – by Nathan Anthony
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.
Cooking with a slow cooker is famously easy, but often we settle down on a few recipes and then don’t vary. This book brings a healthy dose of inspiration and variety.
The recipes themselves range from comfort food to fancy entertaining, pasta dishes to risottos, and even what the author categorizes as “fakeaways” (a play on the British English “takeaway”, cf. AmE “takeout”), so indulgent nights in have never been healthier!
For each recipe, you’ll see a nice simple clear layout of all you’d expect (ingredients, method, etc) plus calorie count, so that you can have a rough idea of how much food each meal is.
In terms of dietary restrictions you may have, there’s quite a variety here so it’ll be easy to find things for all needs, and in addition to that, optional substitutions are mostly quite straightforward too.
Bottom line: if you have a slow cooker but have been cooking only the same three things in it for the past ten years, this is the book to liven things up, while staying healthy!

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.

The Reason You’re Alone
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 are feeling lonely, then there are likely reasons why, as Kurtzgesagt explains:
Why it happens and how to fix it
Many people feel lonely and disconnected, often not knowing how to make new friends. And yet, social connection strongly predicts happiness, while lack of it is linked to diseases and a shorter life.
One mistake that people make is thinking it has to be about shared interests; that can help, but proximity and shared time are much more important.
Another stumbling block for many is that adult responsibilities and distractions (work, kids, technology) often take priority over friendships—but loneliness is surprisingly highest among young people, worsened by the pandemic’s impact on social interactions.
And even when friendships are made, they fade without attention, often accidentally, impacting both people involved. Other friendships can be lost following big life changes such as moving house or the end of a relationship. And for people above a certain advanced age, friendship groups can shrink due to death, if one’s friends are all in the same age group.
But, all is not lost. We can make friends with people of any age, and old friendships can be revived by a simple invitation. We can also take a “build it and they will come” approach, by organizing events and being the one who invites others.
It’s easy to fear rejection—most people do—but it’s worth overcoming for the potential rewards. That said, building friendships requires time, patience, caring about others, and being open about yourself, which can involve a degree of vulnerability too.
In short: be laid-back while still prioritizing friendships, show genuine interest, and stay open to social opportunities.
