Coffee & Your Gut

Coffee, in moderation, is generally considered a healthful drink—speaking for the drink itself, at least! Because the same cannot be said for added sugar, various sorts of creamers, or iced caramelatte mocha frappucino dessert-style drinks:

The Bitter Truth About Coffee (or is it?)

Caffeine, too, broadly has more pros than cons (again, in moderation):

Caffeine: Cognitive Enhancer Or Brain-Wrecker?

Some people will be concerned about coffee and the heart. Assuming you don’t have a caffeine sensitivity (or you do but you drink decaf), it is heart-neutral in moderation, though there are some ways of preparing it that are better than others:

So, what about coffee and the gut?

The bacteria who enjoy a good coffee

Amongst our trillions of tiny friends, allies, associates, and enemies-on-the-inside, which ones like coffee, and what kind of coffee do they prefer?

A big (n=35,214) international multicohort analysis examined the associations between coffee consumption and very many different gut microbial species, and found:

115 species were positively associated with coffee consumption, mostly of the kind considered “friendly”, including ones often included in probiotic supplements, such as various Bifidobacterium and Lactobacillus species.

The kind that was most strongly associated with coffee consumption, however, was Lawsonibacter asaccharolyticus, a helpful little beast who converts chlorogenic acid (one of the main polyphenols in coffee) into caffeic acid, quinic acid, and various other metabolites that we can use.

More specifically: moderate coffee-drinkers, defined as drinking 1–3 cups per day, enjoyed a 300–400% increase in L. asaccharolyticus, while high coffee-drinkers (no, not that kind of high), defined as drinking 4 or more cups of coffee per day, enjoyed a 400–800% increase, compared to “never/rarely” coffee-drinkers (defined as drinking 2 or fewer cups per month).

Things that did not affect the outcome:

  • The coffee-making method—it seems the bacteria are not fussy in this regard, as espresso or brewed, and even instant, yielded the same gut microbiome benefits
  • The caffeine content—as both caffeinated and decaffeinated yielded the same gut microbiome benefits

Want to enjoy coffee, but not keen on the effects of caffeine or the taste of decaffeinated?

Taking l-theanine alongside coffee flattens the curve of caffeine metabolism, and means one can get the benefits without unwanted jitteriness:

  • It’s OK That You’re Not OK – by Megan Devine

    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, be aware: this is not a cheerful book. If you’re looking for something to life your mood after a loss, it will not be this.

    What, then, will you find? A reminder that grief is also the final translation of love, and not necessarily something to be put aside as quickly as possible—or even ever, if we don’t want to.

    Too often, society (and even therapists) will correctly note that no two instances of grief are the same (after all, no two people are, so definitely no two relationships are, so how could two instances of grief be?), but will still expect that if most people can move on quickly from most losses, that you should too, and that if you don’t then there is something pathological at hand that needs fixing.

    Part one of the book covers this (and more) in a lot of detail; critics have called it a diatribe against the current status quo in the field of grief.

    Part two of the book is about “what to do with your grief”, and addresses the reality of grief, how (and why) to stay alive when not doing so feels like a compelling option, dealing with grief’s physical side effects, and calming your mind in ways that actually work (without trying to sweep your grief under a rug).

    Parts three and four are more about community—how to navigate the likely unhelpful efforts a lot of people may make in the early days, and when it comes to those people who can and will actually be a support, how to help them to help you.

    In the category of criticism, she also plugs her own (paid, subscription-based) online community, which feels a little mercenary, especially as while community definitely can indeed help, the prospect of being promptly exiled from it if you stop paying, doesn’t.

    Bottom line: if you have experienced grief and felt like moving on was the right thing to do, then this book isn’t the one for you. If, on the other hand, your grief feels more like something you will carry just as you carry the love you feel for them, then you’ll find a lot about that here.

  • Bamboo Shoots vs Asparagus – 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 bamboo shoots to asparagus, we picked the asparagus.

    Why?

    Both are great! But asparagus does distinguish itself on nutritional density.

    In terms of macros, bamboo starts strong with more protein and fiber, but it’s not a huge amount more; the margins of difference are quite small.

    In the category of vitamins, asparagus wins easily with more of vitamins A, B2, B3, B5, B9, C, E, K, and choline. In contrast, bamboo boasts only more vitamin B6. A clear win for asparagus.

    The minerals line-up is closer; asparagus has more calcium, iron, magnesium, and selenium, while bamboo shoots have more manganese, phosphorus, potassium, and zinc. That’s a 4:4 tie, but asparagus’s margins of difference are larger, and if we need a further tiebreaker, bamboo also contains more sodium, which most people in the industrialized world could do with less of rather than more. So, a small win for asparagus.

    In short, adding up the sections… Bamboo shoots, but asparagus scores, and wins the day. Enjoy both, of course, but if making a pick, then asparagus has more bang-for-buck.

  • The Joy of Movement – by Dr. Kelly McGonigal

    We know that exercise is good for us. Obviously. We know that that exercise will make us feel good. In principle.

    So why is that exercise bike wearing the laundry instead, or the weights bench gathering dust?

    Dr. Kelly McGonigal explores our relationship with exercise, both the formal (organized, planned, exercise that looks like exercise) and the informal (ad hoc, casual, exercise that looks like just having a nice time).

    Moreover: she starts with the why, and moves to the how. The trick she plays on us here is to get us very fired up on the many tangible benefits that will make a big difference in all areas of our lives… And then shows us how easy it can be to unlock those, and how we can make it even easier.

    And as to making it stick? Exercise can be addictive, and/but it’s one of the few addictions that is almost always healthful rather than deleterious. And, there are tricks we can use to heighten that, thresholds that once we pass, we just keep going.

    She also looks at the evolutionary tendency of exercise to be connection-building, as part of a community, friend group, or couple.

    And, yes, she gives attention also to undertaking exercise when circumstances aren’t ideal, or our bodies simply won’t allow certain things.

    In short: if any book can get you shaking off the cobwebs, this is the one.

  • Kidney Beans vs White Beans – 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 kidney beans to white beans, we picked the white.

    Why?

    It was close, and each has its strengths! Bear in mind, these are very closely-related beans. But as we say, there are distinguishing factors…

    In terms of macros, kidney beans have very slightly more fiber and white beans have very slightly more protein. But both are close enough in both of those things to call this a tie in this category.

    When it comes to vitamins, there are two ways of looking at this:

    1. kidney beans have more of vitamins B1, B2, B3, B6, B9, C, and K, while white beans have more vitamin B5, E, and choline
    2. kidney beans have slightly more of some vitamins that don’t usually see a deficiency, while white beans have 31x more vitamin E

    Nevertheless, we’re sticking by our usual method of noting that this is a 7:3 win for kidney beans in this category; we just wanted to note that in practical health terms, an argument can be made for white beans on the vitamin front too.

    In the category of minerals, kidney beans have slightly more phosphorus, while white beans have more calcium, copper, iron, magnesium, manganese, potassium, selenium, and zinc. An easy win for white beans this time.

    (In case you’re wondering about the margin on phosphorus, it was 0.2x more, so we’re not seeing a situation like white beans’ 31x more vitamin E)

    In short: both are great and both have their strengths. Enjoy both, together if you like! But if we have to pick one, we’re going with white beans.

  • Blueberries vs Elderberries – 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 blueberries to elderberries, we picked the elderberries.

    Why?

    Both are certainly top-tier fruits! But…

    In terms of macros, elderberries have more than 2x the fiber, while the two berries are approximately equal on other macros. An easy win for elderberries in this category.

    In the category of vitamins, blueberries have more of vitamins E, K, and choline, while elderberries have more of vitamins A, B1, B2, B3, B5, B6, B7, B9, and C, scoring another win for elderberries here.

    When it comes to minerals, blueberries have more magnesium, manganese, and zinc, while elderberries have more calcium, copper, iron, phosphorus, potassium, and selenium—one more win for elderberries.

    In terms of phytochemicals, both berries are (like most berries) an abundant source of polyphenols, but elderberries have more, including more quercetin, too.

    Adding up the sections makes for a convincing win for elderberries, but by all means enjoy either or both; diversity is good!
