The Bitter Truth About Coffee (or is it?)
Yesterday, we asked you for your (health-related) views on coffee. The results were clear: if we assume the responses to be representative, we’re a large group of coffee-enthusiasts!
One subscriber who voted for “Coffee is a healthy stimulant, hydrating, and full of antioxidants” wrote:
❝Not so sure about how hydrating it is! Like most food and drink, moderation is key. More than 2 or 3 cups make me buzz! Just too much.❞
And that fine point brings us to our first potential myth:
Coffee is dehydrating: True or False?
False. With caveats…
Coffee, in whatever form we drink it, is wet. This may not come as a startling revelation, but it’s an important starting point. It’s mostly water. Water itself is not dehydrating.
Caffeine, however, is a diuretic—meaning you will tend to pee more. It achieves its diuretic effect by increasing blood flow to your kidneys, which prompts them to release more water through urination.
See: Effect of caffeine on bladder function in patients with overactive bladder symptoms
How much caffeine is required to have a diuretic effect? About 4.5 mg/kg.
What this means in practical terms: if you weigh 70kg (a little over 150lbs), 4.5×70 gives us 315.
315mg is about how much caffeine might be in six shots of espresso. We say “might” because while dosage calculations are an exact science, the actual amount in your shot of espresso can vary depending on many factors, including:
- The kind of coffee bean
- How and when it was roasted
- How and when it was ground
- The water used to make the espresso
- The pressure and temperature of the water
…and that’s all without looking at the most obvious factor: “is the coffee decaffeinated?”
If it doesn’t contain caffeine, it’s not diuretic. Decaffeinated coffee does usually contain tiny amounts of caffeine still, but with nearer 3mg than 300mg, it’s orders of magnitude away from having a diuretic effect.
If it does contain caffeine, then the next question becomes: “and how much water?”
For example, an Americano (espresso, with hot water added to make it a long drink) will be more hydrating than a ristretto (espresso, stopped halfway through pushing, meaning it is shorter and stronger than a normal espresso).
A subscriber who voted for “Coffee messes with sleep, creates dependency, is bad for the heart and gut, and is dehydrating too” wrote:
❝Coffee causes tachycardia for me so staying away is best. People with colon cancer are urged to stay away from coffee completely.❞
These are great points! It brings us to our next potential myth:
Coffee is bad for the heart: True or False?
False… For most people.
Some people, like our subscriber above, have an adverse reaction to caffeine, such as tachycardia. An important reason (beyond basic decency) for anyone providing coffee to honor requests for decaff.
For most people, caffeine is “heart neutral”. It doesn’t provide direct benefits or cause direct harm, provided it is enjoyed in moderation.
See also: Can you overdose on caffeine?
Some quick extra notes…
That’s all we have time for in myth-busting, but it’s worth noting before we close that coffee has a lot of health benefits; we didn’t cover them today because they’re not contentious, but they are interesting nevertheless:
- Coffee is the world’s biggest source of antioxidants
- 65% reduced risk of Alzheimer’s for coffee-drinkers
- 67% reduced risk of type 2 diabetes for coffee-drinkers
- 43% reduced risk of liver cancer for coffee-drinkers
- 53% reduced suicide risk for coffee-drinkers
Enjoy!

Eat To Beat Chronic Fatigue!
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.
How To Eat To Beat Chronic Fatigue
Chronic fatigue is on the rise, and it can make life a living Hell. Days blur into one, and you try to take each day as it comes, but sometimes several days gang up on you at once.
You probably know some lifestyle changes that might help—if only you had the energy to implement them.
You’d like to eat well, but you need to…
- Buy the fresh produce (and take a little rest after)
- Put the groceries away (and take a little rest after)
- Wash the vegetables (and take a little rest after)
- Chop the things as necessary (and take a little rest after)
- Cook dinner (and take a little rest after)
…and now you’re too exhausted to eat it.
So, what can be done?
First, avoid things that cause inflammation, as this is a major contributor to chronic fatigue. You might like our previous main feature:
Next up, really do stay hydrated. It’s less about quantity, and more about ubiquity. Hydrate often.
Best is if you always have some (hydrating) drink on the go.
Do experiment with your diet, and/but keep a food journal of what you eat and how you feel 30–60 minutes after eating it. Only make one change at a time, otherwise you won’t know which change made the difference.
Notice what patterns emerge over time, and adjust your ingredients accordingly.
Limit your caffeine intake. We know that sometimes it seems like the only way to get through the day, but you will always crash later, because it was only ever taxing your adrenal system (thus: making you more tired in the long run) and pulling the wool over the eyes of your adenosine receptors (blocking you from feeling how tired you are, but not actually reducing your body’s tiredness).
Put simply, caffeine is the “payday loan” of energy.
Eat more non-starchy vegetables, and enjoy healthy fats. Those healthy fats can come from nuts and seeds, avocado, or fish (not fried, though!).
The non-starchy vegetables will boost your vitamins and fiber while being easy on your beleaguered metabolism, while the healthy fats will perk up your energy levels without spiking insulin like sugars would.
Pay the fatigue tax up front. What this means is… Instead of throwing away vegetables that didn’t get used because it would take too much effort and you just need an easier dinner today, buy ready-chopped vegetables, for example.
And if you buy vegetables frozen, they’re also often not only cheaper, but also (counterintuitively) contain more nutrients.
A note of distinction:
Many more people have chronic fatigue (the symptom: being exhausted all the time) than have chronic fatigue syndrome (the illness: myalgic encephalomyelitis).
This is because fatigue can be a symptom of many, many other conditions, and can be heavily influenced by lifestyle factors too.
A lot of the advice for dealing with chronic fatigue is often the same in both cases, but some will be different, because for example:
- If your fatigue is from some other condition, that condition probably impacts what lifestyle factors you are (and are not) able to change, too
- If your fatigue is from lifestyle factors, that hopefully means you can change those and enjoy less fatigue…
- But if it’s not from lifestyle factors, as in ME/CFS, then advice to “exercise more” etc is not going to help so much.
There are ways to know the difference though:

Exercised – by Dr. Daniel Lieberman
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.
Surely the title is taking liberties? We must have evolved to exercise, right? Not exactly.
We evolved to conserve energy. Our strength-to-weight ratio is generally unimpressive, we cannot casually hang in trees, and we spend a third of our lives asleep.
Strengths that we do have, however, include a large brain and a versatile gut perfect for opportunism. Again, not the indicators of being evolved for exercise.
So, Dr. Lieberman tells us, if we’re not inclined to get up and go, that’s quite natural. So, why does it feel good when we do get up and go?
This book covers a lot of the “this not that” aspects of exercise. By this we mean: ways that we can work with or against our bodies, for both physical and psychological fulfilment.
There’s an emphasis on such things as:
- movement without excessive exertion
- persistence being more important than power
- strength-building but only so far as is helpful to us
…and many other factors that you won’t generally see on your gym’s motivational posters
Bottom line: this book is for all those who have felt “exercise is not for me” but would also like the benefits of exercise. It turns out that there’s a best-of-both-worlds sweet spot!

Optimism Seriously Increases Longevity!
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.
Always look on the bright side for life
❝I’m not a pessimist; I’m a realist!❞
~ every pessimist ever
To believe self-reports, the world is divided between optimists and realists. But how does your outlook measure up, really?
Below, we’ve included a link to a test, and like most free online tests, this is offered “as-is” with the usual caveats about not being a clinical diagnostic tool, this one actually has a fair amount of scientific weight behind it:
❝Empirical testing has indicated the validity of the Optimism Pessimism Instrument as published in the scientific journal Current Psychology: Research and Reviews.
The IDRlabs Optimism/Pessimism Test (IDR-OPT) was developed by IDRlabs. The IDR-OPT is based on the Optimism/Pessimism Instrument (OPI) developed by Dr. William Dember, Dr. Stephanie Martin, Dr. Mary Hummer, Dr. Steven Howe, and Dr. Richard Melton, at the University of Cincinnati.❞
Take This Short (1–2 mins) Test
How did you score? And what could you do to improve on that score?
We said before that we’d do a main feature on this sometime, and today’s the day! Fits with the theme of Easter too, as for those who observe, this is a time for a celebration of hope, new beginnings, and life stepping out of the shadows.
On which note, before we go any further, let’s look at a very big “why” of optimism…
There have been many studies done regards optimism and health, and they generally come to the same conclusion: optimism is simply good for the health.
Here’s an example. It’s a longitudinal study, and it followed 121,700 women (what a sample size!) for eight years. It controlled for all kinds of other lifestyle factors (especially smoking, drinking, diet, and exercise habits, as well as pre-existing medical conditions), so this wasn’t a case of “people who are healthy are more optimistic as a result. And, in the researchers’ own words…
❝We found strong and statistically significant associations of increasing levels of optimism with decreasing risks of mortality, including mortality due each major cause of death, such as cancer, heart disease, stroke, respiratory disease, and infection.
Importantly, findings were maintained after close control for potential confounding factors, including sociodemographic characteristics and depression❞
Read: Optimism and Cause-Specific Mortality: A Prospective Cohort Study
So that’s the why. Now for the how…
Positive thinking is not what you think it is
A lot of people think of “think positive thoughts” as a very wishy-washy platitude, but positive thinking isn’t about ignoring what’s wrong, or burying every negative emotion.
Rather, it is taking advantage of the basic CBT, DBT, and, for that matter, NLP principles:
- Our feelings are driven by our thoughts
- Our thoughts can be changed by how we frame things
This is a lot like the idea that “there’s not such thing as bad weather; only the wrong clothes”. Clearly written by someone who’s never been in a hurricane, but by and large, the principle stands true.
For example…
- Most problems can be reframed as opportunities
- Replace “I have to…” with “I get to…”
- Will the task be arduous? It’ll be all the better looking back on it.
- Did you fail abjectly? Be proud that you lived true to your values anyway.
A lot of this is about focusing on what you can control. If you live your life by your values (first figure out what they are, if you haven’t already), then that will become a reassuring thing that you can always count on, no matter what.
Practice positive self-talk (eliminate the negative)
We often learn, usually as children, to be self deprecatory so as to not appear immodest. While modesty certainly has its place, we don’t have to trash ourselves to do that!
There are various approaches to this, for example:
- Replacing a self-criticism (whether it was true or not) with a neutral or positive statement that you know is true. “I suck at xyz” is just putting yourself down, “Xyz is a challenge for me” asks the question, how will you rise to it?
- Replacing a self-criticism with irony. It doesn’t matter how dripping with sarcasm your inner voice is, the words will still be better. “Glamorous as ever!” after accidentally putting mascara in your eye. “So elegant and graceful!” after walking into furniture. And so on.
Practice radical acceptance
This evokes the “optimistic nihilism” approach to life. It’s perhaps not best in all scenarios, but if you’re consciously and rationally pretty sure something is going to be terrible (and/or know it’s completely outside of your control), acknowledging that possibility (or even, likelihood) cheerfully. Borrowing from the last tip, this can be done with as much irony as you find necessary. For example:
Facing a surgery the recovery from which you know categorically will be very painful: with a big smile “Yep, I am going to be in a lot of pain, so that’s going to be fun!” (fun fact: psychological misery will not make the physical pain any less painful, so you might as well see the funny side) ← see link for additional benefits laughter can add to health-related quality of life)
Plan for the future with love
You know the whole “planting trees in whose shade you’ll never sit”, thing, but: actually for yourself too. Plan (and act!) now, out of love and compassion for your future self.
Simple example: preparing (or semi-preparing, if appropriate) breakfast for yourself the night before, when you know in the morning you’ll be tired, hungry, and/or pressed for time. You’ll wake up, remember that you did that, and…
Tip: at moments like that, take a moment to think “Thanks, past me”. (Or call yourself by your name, whatever works for you. For example I, your writer here, might say to myself “Thanks, past Nastja!”)
This helps to build a habit of gratitude for your past self and love for your future self.
This goes for little things like the above, but it also goes for things whereby there’s much longer-term delayed gratification, such as:
- Healthy lifestyle changes (usually these see slow, cumulative progress)
- Good financial strategies (usually these see slow, cumulative progress)
- Long educational courses (usually these see slow, cumulative progress)
Basically: pay it forward to your future self, and thank yourself later!
Some quick ideas of systems and apps that go hard on the “long slow cumulative progress” approach that you can look back on with pride:
- Noom—nutritional program with a psychology-based approach to help you attain and maintain your goals, long term
- You Need A Budget—we’ve recommended it before and we’ll recommend it again. This is so good. If you click through, you can see a short explanation of what makes it so different to other budgeting apps.
- Duolingo—the famously persistence-motivational language learning app

The Problem With Sweeteners
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.
The WHO’s new view on sugar-free sweeteners
The WHO has released a report offering guidance regards the use of sugar-free sweeteners as part of a weight-loss effort.
In a nutshell, the guidance is: don’t
- Here’s the report itself: Use of non-sugar sweeteners: WHO guideline
- Here’s the WHO’s own press release about it: WHO advises not to use non-sugar sweeteners for weight control in newly released guideline
- And it was based on this huge systematic review: Health effects of the use of non-sugar sweeteners: a systematic review and meta-analysis
They make for interesting reading, so if you don’t have time now, you might want to just quickly open and bookmark them for later!
Some salient bits and pieces:
Besides that some sweeteners can cause gastro-intestinal problems, a big problem is desensitization:
Because many sugar substitutes are many times (in some cases, hundreds of times) sweeter than sugar, this leads to other sweet foods tasting more bland, causing people to crave sweeter and sweeter foods for the same satisfaction level.
You can imagine how that’s not a spiral that’s good for the health!
The WHO recommendation applies to artificial and naturally-occurring non-sugar sweeteners, including:
- Acesulfame K
- Advantame
- Aspartame
- Cyclamates
- Neotame
- Saccharin
- Stevia
Sucralose and erythritol, by the way, technically are sugars, just not “that kind of sugar” so they didn’t make the list of non-sugar sweeteners.
That said, a recent study did find that erythritol was linked to a higher risk of heart attack, stroke, and early death, so it may not be an amazing sweetener either:
Read: The artificial sweetener erythritol and cardiovascular event risk
Want to know a good way of staying healthy in the context of sweeteners?
Just get used to using less. Your taste buds will adapt, and you’ll get just as much pleasure as before, from progressively less sweetening agent.

Heart Smarter for Women – by Dr. Jennifer Mieres
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. Mieres takes us through understanding our own heart disease risks as individuals rather than as averages. As the title suggests, she does assume a female readership, so if you are a man and have no female loved ones, this might not be the book for you. But aside from that, she walks us through examining risk in the context of age, other health conditions, lifestyle factors, and so forth—including not turning a blind eye to factors that might intersect, such as for example if a physical condition reduces how much we can exercise, or if there’s some reason we can’t follow the usual gold standard of heart-healthy diet.
On which note, she does offer dietary advice, including information around recipes, meal-planning, and what things to always have in stock, as well as what things matter the most when it comes to what and how we eat.
It’s not all lifestyle medicine though; Dr. Mieres gives due attention to many of the medications available for heart health issues—and the pros and cons of these.
The style of the book is very simple and readable pop-science, without undue jargon, and with a generous glossary. As with many books of this genre, it does rely on (presumably apocryphal) anecdotes, though an interesting choice for this book is that it keeps a standing cast of four recurring characters, each to represent a set of circumstances and illustrate how certain things can go differently for different people, with different things then being needed and/or possible. Hopefully, any given reader will find themself represented at least moderately well somewhere in or between these four characters.
Bottom line: this is a very informative and accessible book, that demystifies a lot of common confusions around heart health.

CBD Against Diabetes!
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
❝CBD for diabetes! I’ve taken CBD for body pain. Did no good. Didn’t pay attention as to diabetes. I’m type 1 for 62 years. Any ideas?❞
Thanks for asking! First up, for reference, here’s our previous main feature on the topic of CBD:
CBD Oil: What Does The Science Say?
There, we touched on CBD’s effects re diabetes:
in mice / in vitro / in humans
In summary, according to the above studies, it…
- lowered incidence of diabetes in non-obese diabetic mice. By this they mean that pancreatic function improved (reduced insulitis and reduced inflammatory Th1-associated cytokine production). Obviously this has strong implications for Type 1 Diabetes in humans—but so far, just that, implications (because you are not a mouse).
- attenuated high glucose-induced endothelial cell inflammatory response and barrier disruption. Again, this is promising, but it was an in vitro study in very controlled lab conditions, and sometimes “what happens in the Petri dish, stays in the Petri dish”—in order words, these results may or may not translate to actual living humans.
- Improved insulin response ← is the main take-away that we got from reading through their numerical results, since there was no convenient conclusion given. Superficially, this may be of more interest to those with type 2 diabetes, but then again, if you have T1D and then acquire insulin resistance on top of that, you stand a good chance of dying on account of your exogenous insulin no longer working. In the case of T2D, “the pancreas will provide” (more or less), T1D, not so much.
So, what else is there out there?
The American Diabetes Association does not give a glowing review:
❝There’s a lot of hype surrounding CBD oil and diabetes. There is no noticeable effect on blood glucose (blood sugar) or insulin levels in people with type 2 diabetes. Researchers continue to study the effects of CBD on diabetes in animal studies. ❞
~ American Diabetes Association
Source: ADA | CBD & Diabetes
Of course, that’s type 2, but most research out there is for type 2, or else have been in vitro or rodent studies (and not many of those, at that).
Here’s a relatively more recent study that echoes the results of the previous mouse study we mentioned; it found:
❝CBD-treated non-obese diabetic mice developed T1D later and showed significantly reduced leukocyte activation and increased FCD in the pancreatic microcirculation.
Conclusions: Experimental CBD treatment reduced markers of inflammation in the microcirculation of the pancreas studied by intravital microscopy. ❞
~ Dr. Christian Lehmann et al.
Read more: Experimental cannabidiol treatment reduces early pancreatic inflammation in type 1 diabetes
…and here’s a 2020 study (so, more recent again) that was this time rats, and/but still more promising, insofar as it was with rats that had full-blown T1D already:
Read in full: Two-weeks treatment with cannabidiol improves biophysical and behavioral deficits associated with experimental type-1 diabetes
Finally, a paper in July 2023 (so, since our previous article about CBD), looked at the benefits of CBD against diabetes-related complications (so, applicable to most people with any kind of diabetes), and concluded:
❝CBDis of great value in the treatment of diabetes and its complications. CBD can improve pancreatic islet function, reduce pancreatic inflammation and improve insulin resistance. For diabetic complications, CBD not only has a preventive effect but also has a therapeutic value for existing diabetic complications and improves the function of target organs❞
…before continuing:
❝However, the safety and effectiveness of CBD are still needed to prove. It should be acknowledged that the clinical application of CBD in the treatment of diabetes and its complications has a long way to go.
The dissecting of the pharmacology and therapeutic role of CBD in diabetes would guide the future development of CBD-based therapeutics for treating diabetes and diabetic complications❞
~ Ibid.
Now, the first part of that is standard ass-covering, and the second part of that is standard “please fund more studies please”. Nevertheless, we must also not fail to take heed—little is guaranteed, especially when it comes to an area of research where the science is still very young.
In summary…
It seems well worth a try, and with ostensibly nothing to lose except the financial cost of the CBD.
If you do, you might want to keep careful track of a) your usual diabetes metrics (blood sugar levels before and after meals, insulin taken), and b) when you took CBD, what dose, etc, so you can do some citizen science here.
Lastly: please remember our standard disclaimer; we are not doctors, let alone your doctors, so please do check with your endocrinologist before undertaking any such changes!
