Grapefruit vs Lemon – 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 grapefruit to lemon, we picked the lemon.
Why?
Grapefruit has its merits, but in the battle of the citrus fruits, lemons come out on top nutritionally:
In terms of macros, grapefruit has more carbs while lemons have more fiber. So, while both have a low glycemic index, lemon is still the winner by the numbers.
Looking at the vitamins, here we say grapefruit’s strengths: grapefruit has more of vitamins A, B2, B3, and choline, while lemon has more of vitamins B6 and C. So, a 4:2 win for grapefruit here.
In the category of minerals, lemons retake the lead: grapefruit has more zinc, while lemon has more calcium, copper, iron, manganese, and selenium.
One final consideration that’s not shown in the nutritional values, is that grapefruit contains high levels of furanocoumarin, which can inhibit cytochrome P-450 3A4 isoenzyme and P-glycoptrotein transporters in the intestine and liver—slowing down their drug metabolism capabilities, thus effectively increasing the bioavailability of many drugs manifold.
This may sound superficially like a good thing (improving bioavailability of things we want), but in practice it means that in the case of many drugs, if you take them with (or near in time to) grapefruit or grapefruit juice, then congratulations, you just took an overdose. This happens with a lot of meds for blood pressure, cholesterol (including statins), calcium channel-blockers, anti-depressants, benzo-family drugs, beta-blockers, and more. Oh, and Viagra, too. Which latter might sound funny, but remember, Viagra’s mechanism of action is blood pressure modulation, and that is not something you want to mess around with unduly. So, do check with your pharmacist to know if you’re on any meds that would be affected by grapefruit or grapefruit juice!
PS: the same substance is quite available in pummelos and sour oranges (but not meaningfully in sweet oranges); you can see a chart here showing the relative furanocoumarin contents of many citrus fruits, or lack thereof as the case may be, as it is for lemons and most limes)
Adding up the sections gives us a clear win for lemons, but by all means enjoy either or both; just watch out for that furanocoumarin content of grapefruit if you’re on any meds affected by such (again, do check with your pharmacist, as our list was far from exhaustive—and yes, this question is one that a pharmacist will answer more easily and accurately than a doctor will).

Dates vs Banana – 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 dates to banana, we picked the dates.
Why?
It was close, and bananas do have some strengths too! We pitted these two against each other as they’re both sweet fruits often used as a sweetening and consistency-altering ingredient in desserts and sweet snacks, so if you’re making a choice between them, here are the things to consider:
In terms of macros, dates have more than 3x the fiber, more than 2x the protein, and a little over 3x the carbs. You may be wondering how this adds up in terms of glycemic index: dates have the lower GI. So, we pick dates, here, for that reason and overall nutritional density too.
When it comes to vitamins, bananas have their moment, albeit barely: dates have more of vitamins B1, B3, B5, and K, while bananas have more of vitamins A, B6, C, E, and choline, making for a marginal victory for bananas in this category.
Looking at minerals next, however, it’s quite a different story: dates have more calcium, copper, iron, magnesium, phosphorus, potassium, selenium, and zinc, while bananas are not higher in any mineral. No, not even potassium, for which they are famous—dates have nearly 2x more potassium than bananas.
Adding up these sections makes for a clear win for dates in general!
Enjoy either/both, but dates are the more nutritious snack/ingredient.

A Guide to the Good Life – by Dr. William Irvine
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.
“Living well” is a surprisingly underrated part of wellness. We spend much of our lives in turmoil. Some of us, windswept and battered by the storms of life; others, up in quietly crumbling towers, seemingly “great” but definitely not feeling it. Diet and exercise etc will only get us so far. What else, then, can we do?
For Dr. Irvine, the key lies in two main things:
- Deciding how we intend to live our life (and doing so)
- Remaining tranquil in the face of external stressors
In Japanese terms, these things can be seen in ikigai and zen, respectively. This book puts them in Western terms, specifically, that of Stoic philosophy. But the goals and methods are very similar.
Far from being an abstract tome of wishy-washy philosophy, this book offers down-to-earth practical exercises and easily applicable advice. There was even an exercise that was new to this reviewer who has been reading such things for decades.
The writing style is also, true to Stoic principles, unpretentious and simple. This is an easy book to read, while being nonethless very engaging from start to finish—and thereafter!
Bottom line: so far as we know, we only get one shot at life, so we might as well make it a good one. Applying the ideas found in this book can help any reader to live better, and take more joy in it along the way.

Heart Health vs Systemic Stress
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.
At The Heart Of Good Health
This is Dr. Michelle Albert. She’s a cardiologist with a decades-long impressive career, recently including a term as the president of the American Heart Association. She’s the current Admissions Dean at UCSF Medical School. She’s accumulated enough awards and honors that if we list them, this email will not fit in your inbox without getting clipped.
What does she want us to know?
First, lifestyle
Although Dr. Albert is also known for her work with statins (which found that pravastatin may have anti-inflammatory effects in addition to lipid-lowering effects, which is especially good news for women, for whom the lipid-lowering effects may be less useful than for men), she is keen to emphasize that they should not be anyone’s first port-of-call unless “first” here means “didn’t see the risk until it was too late and now LDL levels are already ≥190 mg/dL”.
Instead, she recommends taking seriously the guidelines on:
- getting plenty of fruit, vegetables, whole grains, lean protein
- avoiding red meat, processed meats, refined carbohydrates, and sweetened beverages
- getting your 150 minutes per week of moderate exercise
- avoiding alcohol, and definitely abstaining from smoking

Next, get your house in order
No, not your home gym—though sure, that too!
But rather: after the “Top Five Things” we linked just above, the sixth on the list would be “reduce stress”. Indeed, as Dr. Albert says:
❝Heart health is not just about the physical heart but also about emotional well-being. Stress management is crucial for a healthy heart❞
~ Dr. Michelle Albert
This is where a lot of people would advise mindfulness meditation, CBT, somatic therapies, and the like. And these things are useful! See for example:
No-Frills, Evidence-Based Mindfulness
…and:
However, Dr. Albert also advocates for awareness of what some professionals have called “Shit Life Syndrome”.
This is more about socioeconomic factors. There are many of those that can’t be controlled by the individual, for example:
❝Adverse maternal experiences such as depression, economic issues and low social status can lead to poor cognitive outcomes as well as cardiovascular disease.
Many jarring statistics illuminate a marked wealth gap by race and ethnicity… You might be thinking education could help bridge that gap. But it is not that simple.
While education does increase wealth, the returns are not the same for everyone. Black persons need a post-graduate degree just to attain similar wealth as white individuals with a high school degree.❞
~ Dr. Michelle Albert
Read in full: AHA president: The connection between economic adversity and cardiovascular health
What this means in practical terms (besides advocating for structural change to tackle the things such as the racism that has been baked into a lot of systems for generations) is:
Be aware not just of your obvious health risk factors, but also your socioeconomic risk factors, if you want to have good general health outcomes.
So for example, let’s say that you, dear reader, are wealthy and white, in which case you have some very big things in your favor, but are you also a woman? Because if so…
Women and Minorities Bear the Brunt of Medical Misdiagnosis
See also, relevant for some: Obesity Discrimination In Healthcare Settings ← you’ll need to scroll to the penultimate section for this one.
In other words… If you are one of the majority of people who is a woman and/or some kind of minority, things are already stacked against you, and not only will this have its own direct harmful effect, but also, it’s going to make your life harder and that stress increases CVD risk more than salt.
In short…
This means: tackle not just your stress, but also the things that cause that. Look after your finances, gather social support, know your rights and be prepared to self-advocate / have someone advocate for you, and go into medical appointments with calm well-prepared confidence.
Take care!

Change Your Brain, Change Your Life – by Dr. Daniel G. Amen
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.
To what extent can we change our brains, and to what extent are we stuck with what we have?
Dr. Amen tells us that being mindful of both ends of this is critical:
- Neuroplasticity means we can, indeed, change our brains
- We do, however, have fundamental “brain types” based on our neurochemistry and physical brain structure
He argues for the use of brain imaging technology to learn more about the latter… In order to better go about doing what we can with the former.
The book looks at how these different brain types can lead to situations where what works as a treatment for one person can often not work for another. It’s also prescriptive, about what sorts of treatments (and lifestyle adjustments) are more likely to do better for each.
Where the book excels is in giving ideas and pointers for exploration… Things to take to one’s doctor, and—for example—request certain tests, and then what to do with those.
Where the book is a little light is on including hard science in the explanations. The hard science is referred to, but is considered beyond the scope of the book, or perhaps beyond the interest of the reader. That’s unfortunate, as we’d have liked to have seen more of it, rather than taking claims at face value without evidence.
Bottom line: this is distinctly “pop science” in presentation, but can give a lot of great ideas for learning more about our own brains and brain health… And then optimizing such.

Do We Need Sunscreen In Winter, Really?
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 😎
❝I keep seeing advice that we shoudl wear sunscreen out in winter even if it’s not hot or sunny, but is there actually any real benefit to this?❞
Short answer: yes (but it’s indeed not as critical as it is during summer’s hot/sunny days)
Longer answer: first, let’s examine the physics of summer vs winter when it comes to the sun…
In summer (assuming we live far enough from the equator to have this kind of seasonal variation), the part of the planet where we live is tilted more towards the sun. This makes it closer, and more importantly, it’s more directly overhead during the day. The difference in distance through space isn’t as big a deal as the difference in distance through the atmosphere. When the sun is more directly overhead, its rays have a shorter path through our atmosphere, and thus less chance of being blocked by cloud cover / refracted elsewhere / bounced back off into space before it even gets that far.
In winter, the opposite of all that is true.
Morning/evening also somewhat replicate this compared to midday, because the sun being lower in the sky has a similar effect to seasonal variation causing it to be less directly overhead.
For this reason, even though visually the sun may be just as bright on a winter morning as it is on a summer midday, the rays have been filtered very differently by the time they get to us.
This is one reason why you’re much less likely to get sunburned in the winter, compared to the summer (others include the actual temperature difference, your likely better hydration, and your likely more modest attire protecting you).
However…
The reason it is advisable to wear sunscreen in winter is not generally about sunburn, and is rather more about long-term cumulative skin damage (ranging from accelerated aging to cancer) caused by the UV rays—specifically, mostly UVA rays, since UVB rays (with their higher energy but shorter wavelength) have nearly all been blocked by the atmosphere.
Here’s a good explainer of that from the American Cancer Society:
UV (Ultraviolet) Radiation and Cancer Risk
👆 this may seem like a no-brainer, but there’s a lot explained here that demystifies a lot of things, covering ionizing vs non-ionizing radiation, x-rays and gamma-rays, the very different kinds of cancer caused by different things, and what things are dangerous vs which there’s no need to worry about (so far as best current science can say, at least).
Consequently: yes, if you value your skin health and avoidance of cancer, wearing sunscreen when out even in the winter is a good idea. Especially if your phone’s weather app says the UV index is “moderate” or above, but even if it’s “low”, it doesn’t hurt to include it as part of your skincare routine.
But what if sunscreens are dangerous?
Firstly, not all sunscreens are created equal:
Learn more: Who Screens The Sunscreens?
Secondly: consider putting on a protective layer of moisturizer first, and then the sunscreen on top. Bear in mind, this is winter we’re talking about, so you’re probably not going out in a bikini, so this is likely a face-neck-hands job and you’re done.
What about vitamin D?
Humans evolved to have more or less melanin in our skin depending on where we lived, and white people evolved to wring the most vitamin D possible out of the meagre sun far from the equator. Black people’s greater melanin, on the other hand, offers some initial protection against the sun (but any resultant skin cancer is then more dangerous than it would be for white people if it does occur, so please do use sunscreen whatever your skintone).
Nowadays many people live in many places which may or may not be the places we evolved for, and so we have to take that into account when it comes to sun exposure.
Here’s a deeper dive into that, for those who want to learn:
