Our Verdict
When comparing black beans to fava beans, we picked the black beans.
Why?
In terms of macros, black beans have more protein, carbs, and notably more fiber, the ratio of the latter two also being such that black beans enjoy the lower glycemic index (but both are still good). All in all, a clear win for black beans in this category.
In the category of vitamins, black beans have more of vitamins B1, B5, B6, E, K, and choline, while fava beans have more of vitamins A, B2, B3, B9, and C. That’s a marginal 6:5 win for black beans, before we take into account that they also have 43x as much vitamin E, which is quite a margin, while fava beans doesn’t have any similarly stand-out nutrient. So, another clear win for black beans.
When it comes to minerals, black beans have more calcium, copper, iron, magnesium, phosphorus, and potassium, while fava beans have more manganese, selenium, and zinc. Superficially this is a 6:3 win for black beans; it’s worth noting however that the margins aren’t high on either side in the case of any mineral, so this one’s closer than it looks. Still a win for black beans, though.
Adding up the sections makes for an easy overall win for black beans, but by all means, enjoy either or both—diversity is good!

Pistachios vs Brazil Nuts – 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 pistachios to Brazil nuts, we picked the pistachios.
Why?
In terms of macros, pistachios have more protein, carbs, and fiber, while Brazil nuts have more fat. The fats are mostly healthy, although it is worth noting that Brazil nuts have not only more total saturated fat, but also more saturated fat proportionally to total fats. All in all, Brazil nuts’ macro balance isn’t bad, but we say pistachios have it better.
When it comes to vitamins, pistachios have a lot more of vitamins A, B1, B2, B3, B5, B6, B7, B9, and C, while Brazil nuts have more vitamin E. An easy win for pistachios here.
In the category of minerals, it gets interesting: pistachios have more iron and potassium, while Brazil nuts have more calcium, copper, magnesium, phosphorus, selenium, and zinc. Sounds great, but… About that selenium:
- A cup of cashews contains 38% of the RDA of selenium. This will go towards helping your hair be luscious and shiny (also important for energy conversion).
- A cup of Brazil nuts contains 10,456% of the RDA of selenium. This is way past the point of selenium toxicity, and your (luscious, shiny) hair will fall out.
For this reason, it’s recommended to eat no more than 3–4 Brazil nuts per day.
We consider that a point against Brazil nuts.
Adding up the sections gives us an overall win for pistachios. Of course, enjoy Brazil nuts too if you will, but in careful moderation please!

The Mediterranean Diet: What Is It Good For?
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.
More to the point: what isn’t it good for?
- It’s been found to reduce all-cause mortality, which is about the best thing one can say of any diet.
- It’s especially good for heart health and against cancer.
- It’s particularly recommended for the prevention or management of diabetes.
- It’s also been found, societally, to reduce general healthcare costs—basically, people get sick less and so have fewer healthcare costs.
What brought it to the attention of the world’s scientific community?
Back in the 1950s, physiologist Ancel Keys wondered why poor people in Italian villages were healthier than wealthy New Yorkers. Upon undertaking studies, he narrowed it down to the Mediterranean diet—something he’d then take on as a public health cause for the rest of his career.
Keys himself lived to the ripe old age of 100, by the way.
When we say “Mediterranean Diet”, what image comes to mind?
We’re willing to bet that tomatoes feature (great source of lycopene, by the way), but what else?
- Salads, perhaps? Vegetables, olives? Olive oil, yea or nay?
- Bread? Pasta? Prosciutto, salami? Cheese?
- Pizza but only if it’s Romana style, not Chicago?
- Pan-seared liver, with some fava beans and a nice Chianti?
In reality, the diet is based on what was historically eaten specifically by Italian peasants. If the word “peasants” conjures an image of medieval paupers in smocks and cowls, and that’s not necessarily wrong, further back historically… but the relevant part here is that they were people who lived and worked in the countryside.
They didn’t have money for meat, which was expensive, nor the industrial setting for refined grain products to be affordable. They didn’t have big monocrops either, which meant no canola oil, for example… Olives produce much more easily extractable oil per plant, so olive oil was easier to get. Nor, of course, did they have the money (or infrastructure) for much in the way of imports.
So what foods are part of “the” Mediterranean Diet?
- Fruits. These would be fruits grown locally, but no need to sweat that, dietwise. It’s hard to go wrong with fruit.
- Tomatoes yes. So many tomatoes. (Knowledge is knowing tomato is a fruit. Wisdom is not putting it in a fruit salad)
- Non-starchy vegetables (e.g. eggplant yes, potatoes no)
- Greens (spinach, kale, lettuce, all those sorts of things)
- Beans and other legumes (whatever was grown nearby)
- Whole grain products in moderation (wholegrain bread, wholewheat pasta)
- Olives and olive oil. Special category, single largest source of fat in the Mediterranean diet, but don’t overdo it.
- Dairy products in moderation (usually hard cheeses, as these keep well)
- Fish, in moderation. Typically grilled, baked, steamed even. Not fried.
- Other meats as a rarer luxury in considerable moderation. There’s more than one reason prosciutto is so thinly sliced!

Mango vs Papaya – 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 mango to papaya, we picked the mango.
Why?
Both are great! But there are some things to set them apart:
In terms of macros, this one’s not so big of a difference. They are equal in fiber, while mango has more protein and slightly more carbs. They are both low glycemic index, so we’ll call this one a tie, or the slenderest nominal win for papaya.
When it comes to vitamins, mango has more of vitamins A, B1, B3, B5, B7, B9, E, K, and choline, while papaya has more vitamin C. However, a cup of mango already gives the RDA of vitamin C, so at this point, it’s not even really much of a bonus that papaya has more. In any case, a clear and overwhelming win in the vitamins category for mango.
As for minerals, this one’s closer; mango has more copper, manganese, phosphorus, and zinc, while papaya has more calcium, iron, and magnesium. Still, a 4:3 win for mango.
Adding these up makes for a clear win for mango. However, one extra thing to bear in mind about both:
Both of these fruits interact with warfarin and many other anticoagulants. So if you’re taking those, you might want to skip these, or at least consult with your doctor/pharmacist for input on your personal situation.
Aside from that; enjoy both; diversity is good! But mango is the more nutritionally dense, and thus the winner here.

Aspirin, CVD Risk, & Potential Counter-Risks
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.
Aspirin Pros & Cons
In Tuesday’s newsletter, we asked your health-related opinion of aspirin, and got the above-depicted, below-described set of responses:
- About 42% said “Most people can benefit from low-dose daily use to lower CVD risk”
- About 31% said “It’s safe for occasional use as a mild analgesic, but that’s all”
- About 28% said “We should avoid aspirin; it can cause liver and/or kidney damage”
So, what does the science say?
Most people can benefit from low-dose daily aspirin use to lower the risk of cardiovascular disease: True or False?
True or False depending on what we mean by “benefit from”. You see, it works by inhibiting platelet function, which means it simultaneously:
- decreases the risk of atherothrombosis
- increases the risk of bleeding, especially in the gastrointestinal tract
When it comes to balancing these things and deciding whether the benefit merits the risk, you might be asking yourself: “which am I most likely to die from?” and the answer is: neither
While aspirin is associated with a significant improvement in cardiovascular disease outcomes in total, it is not significantly associated with reductions in cardiovascular disease mortality or all-cause mortality.
In other words: speaking in statistical generalizations of course, it may improve your recovery from minor cardiac events but is unlikely to help against fatal ones
The current prevailing professional (amongst cardiologists) consensus is that it may be recommended for secondary prevention of ASCVD (i.e. if you have a history of CVD), but not for primary prevention (i.e. if you have no history of CVD). Note: this means personal history, not family history.
In the words of the Journal of the American College of Cardiology:
❝Low-dose aspirin (75-100 mg orally daily) might be considered for the primary prevention of ASCVD among select adults 40 to 70 years of age who are at higher ASCVD risk but not at increased bleeding risk (S4.6-1–S4.6-8).
Low-dose aspirin (75-100 mg orally daily) should not be administered on a routine basis for the primary prevention of ASCVD among adults >70 years of age (S4.6-9).
Low-dose aspirin (75-100 mg orally daily) should not be administered for the primary prevention of ASCVD among adults of any age who are at increased risk of bleeding (S4.6-10).❞
~ Dr. Donna Arnett et al. (those section references are where you can find this information in the document)
Read in full: Guideline on the Primary Prevention of Cardiovascular Disease: A Report of the American College of Cardiology
Or if you’d prefer a more pop-science presentation:
Many older adults still use aspirin for CVD prevention, contrary to clinical guidance
Aspirin can cause liver and/or kidney damage: True or False?
True, but that doesn’t mean we must necessarily abstain, so much as exercise caution.
Aspirin is (at recommended doses) not usually hepatotoxic (toxic to the liver), but there is a strong association between aspirin use in children and the development of Reye’s syndrome, a disease involving encephalopathy and a fatty liver. For this reason, most places have an official recommendation that aspirin not be used by children (cut-off age varies from place to place, for example 12 in the US and 16 in the UK, but the key idea is: it’s potentially dangerous for those who are not fully grown).
Aspirin is well-established as nephrotoxic (toxic to the kidneys), however, the toxicity is sufficiently low that this is not expected to be a problem to otherwise healthy adults taking it at no more than the recommended dose.

South Indian-Style Chickpea & Mango Salad
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.
We have a double-dose of chickpeas today, but with all the other ingredients, this dish is anything but boring. Fun fact about chickpeas though: they’re rich in sitosterol, a plant sterol that, true to its name, sits on cholesterol absorption sites, reducing the amount of dietary cholesterol absorbed. If you are vegan, this will make no difference to you because your diet does not contain cholesterol, but for everyone else, this is a nice extra bonus!
You will need
- 1 can white chickpeas, drained and rinsed
- 1 can black chickpeas (kala chana), drained and rinsed
- 9 oz fresh mango, diced (or canned is fine if that’s what’s available)
- 1½ oz ginger, peeled and grated
- 2 green chilis, finely chopped (adjust per heat preferences)
- 2 tbsp desiccated coconut (or 3 oz grated coconut, if you have it fresh)
- 8 curry leaves (dried is fine if that’s what’s available)
- 1 tsp mustard seeds
- 1 tsp cumin seeds
- 1 tsp black pepper, coarse ground
- ½ tsp MSG or 1 tsp low-sodium salt
- Juice of 1 lime
- Extra virgin olive oil
Method
(we suggest you read everything at least once before doing anything)
1) Heat some oil in a skillet over a medium heat. When it’s hot but not smoking, add the ginger, chilis, curry leaves, mustard seeds, and cumin seeds, stirring well to combine, keep going until the mustard seeds start popping.
2) Add the chickpeas (both kinds), as well as the black pepper and the MSG/salt. Once they’re warm through, take it off the heat.
3) Add the mango, coconut, and lime juice, mixing thoroughly.
4) Serve warm, at room temperature, or cold:
Enjoy!

How (And Why) To Train Your Pre-Frontal Cortex
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. Chapman’s Keys For Mental Focus
This is Dr. Sandra Chapman; she’s a cognitive neuroscientist, on a mission to, in her words, further our understanding of:
- what makes the brain stronger, faster and last longer
- what enhances human cognitive capacity, and
- what enhances the underlying brain systems across the lifespan.
To this end, she’s also the founder and Chief Director of the Center For Brain Health, where she has worked on her mission for the past 25 years (clocking up hundreds of peer-reviewed publications to her name), as well as being a professor of Behavioral and Brain Sciences at UT Dallas.
What does she want us to know?
Get your brain into gear
When it comes to your brainpower, it is “use it or lose it”, but it is also perfectly possible to use it and lose it.
Why?
Very often, what we are using our brains for is high-strain, low-yield stuff, such as multitasking, overthinking, or overthinking while multitasking. And to make it worse, we often do it without sufficient rest.
This is the equivalent of owning a Ferrari but trying to drive it in second and third gear at once by switching between the two as rapidly as possible. And doing that for 18 hours each day.
Suffice it to say, you’ll be going nowhere quickly.
An alternative “use” of brainpower is low-strain, low-yield stuff, such as having to pay close attention to a boring conversation. It’s enough to stop your mind from doing anything else, but not enough to actually stimulate you.
This is the equivalent of owning a Ferrari but keeping it idling. The wear and tear is minimal this time, but you’re not actually going anywhere either.
Better, of course, are the other two quadrants:
- low-strain, high-yield: consistently using our brain in relatively non-taxing ways that encourage its development
- high-strain, high-yield: here the Ferrari metaphor definitely fails, because unlike cars, our bodies (including our brains) are machines that benefit from judicious regular progressive overloading (but just by a bit, and with adequate recovery time between overloads).
See also: 12 Weeks To Measurably Boost Your Brain
How to do the “low-strain, low-yield” part
When it comes to “what’s the most important part of the brain to help in the face of cognitive decline?” the usual answer is either to focus on memory (hippocampi) or language (various parts, but for example Wernicke’s area and Broca’s area), since people most fear losing memory, and language is very important both socially and practically.
Those are indeed critical, and we at 10almonds stand by them, but Dr. Chapman (herself having originally trained as speech and language pathologist!) makes a strong case for adding a third brain part to the list.
Specifically, she advocates for strengthening the pre-frontal cortex, which is responsible for inhibition, task-switching, working memory, and cognitive flexibility. If that seems like a lot, do remember it’s a whole cortex and not one of the assorted important-but-small brain bits we mentioned above.
How? She has developed training programs for this, based on what she calls Strategic Memory Advanced Reasoning Tactics (SMART), to support support attention, planning, judgment and emotional management.
You can read more about those programs here:
Center For Brain Health | Our Programs
Participation in those is mostly not free, however, if you join their…
Center For Brain Health | BrainHealth Project
…then they will periodically invite you to join pilot programs, research programs, and the like, which will either be free or they-pay-you affairs—because this is how science is done, and you can read about yourself (anonymized, of course) later in peer-reviewed papers of the kind we often cite here.
If you’re not interested in any of that though, we will say that according to Dr. Chapman, the keys are:
Inhibition: be conscious of this function of your brain, and develop it. This is the function of your brain that stops you from making mistakes—or put differently: stops you from saying/doing something stupid.
Switching: do this consciously; per “I am now doing this task, now I am switching to this other task”, rather than doing the gear-grinding thing we discussed earlier
Working memory: this is effectively your brain’s RAM. Unlike the RAM of a computer (can be enhanced by adding another chip or replacing with a bigger chip), our brain’s RAM can be increased by frequent use, and especially by judicious use of progressive overloading (with rests between!) which we’ll discuss in the high-strain, high-yield section.
Flexibility: this is about creative problem-solving, openness to new ideas, and curiosity
See also: Curiosity Kills The Neurodegeneration
How to do the “high-strain, high-yield” part
Delighting this chess-playing writer, Dr. Chapman recommends chess. Although, similar games such as go (a Chinese game that looks simpler than chess but actually requires more calculation) work equally well too.
Why?
Games like chess and go cause structural changes that are particularly helpful, in terms of engaging in such foundational tasks as learning, abstract reasoning, problem-solving and self-control:
Chess Practice as a Protective Factor in Dementia
Basically, it checks (so to speak) a lot of boxes, especially for the pre-frontal cortex. Some notes:
- Focusing on the game is required for brain improvement; simply pushing wood casually will not do it. Ideally, calculating several moves ahead will allow for strong working memory use (because to calculate several moves ahead, one will have to hold increasingly many possible positions in the mind while doing so).
- The speed of play must be sufficiently slow as to allow not only for thinking, but also for what in chess is called “blunder-checking”, in other words, having decided on one’s move, pausing to consider whether it is a mistake, and actively trying to find evidence that it is. This is the crucial “inhibition habit”, and when one does it reflexively, one will make fewer mistakes. Tying this to dementia, see for example how one of the common symptoms of dementia is falling for scams that one wouldn’t have previously. How did cognitive decline make someone naïve? It didn’t, per se; it just took away their ability to, having decided what to do, pause to consider whether it was a mistake, and actively trying to find evidence that it is.
- That “conscious switching” that we talked about, rather than multitasking? In chess, there is a difference between strategy and tactics. Don’t worry about what that difference is for now (learn it if you want to take up chess), but know that strong players will only strategize while it is their opponent’s turn, and only calculate (tactics) while it is their own turn. It’s very tempting to flit constantly between one and the other, but chess requires players to have the mental discipline be able to focus on one task or the other and stick with that task until it’s the appointed time to switch.
If you feel like taking up chess, this site (and related app, if you want it) is free (it’s been funded by voluntary donations for a long time now) and good and even comes with free tuition and training tools: LiChess.org
Here’s another site that this writer (hi, it’s me) personally uses—it has great features too, but many are paywalled (I’m mostly there just because I’ve been there nearly since its inception, so I’m baked into the community now): Chess.com
