What’s Your Plant Diversity Score?

We speak often about the importance of dietary diversity, and of that, especially diversity of plants in one’s diet, but we’ve never really focused on it as a main feature, so that’s what we’re going to do today.

Specifically, you may have heard the advice to “eat 30 different kinds of plants per week”. But where does that come from, and is it just a number out of a hat?

The magic number?

It is not, in fact, a number out of a hat. It’s from a big (n=11,336) study into what things affect the gut microbiome for better or for worse. It was an observational population study, championing “citizen science” in which volunteers tracked various things and collected and sent in various samples for analysis.

The most significant finding of this study was that those who consumed more than 30 different kinds of plants per week, had a much better gut microbiome than those who consumed fewer than 10 different kinds of plants per week (there is a bell curve at play, and it gets steep around 10 and 30):

American Gut: an Open Platform for Citizen Science Microbiome Research

Why do I care about having a good gut microbiome?

Gut health affects almost every other kind of health; it’s been called “the second brain” for the various neurotransmitters and other hormones it directly makes or indirectly regulates (which in turn affect every part of your body), and of course there is the vagus nerve connecting it directly to the brain, impacting everything from food cravings to mood swings to sleep habits.

Any other benefits?

Yes there are! Let’s not forget: as we see often in our “This or That” section, different foods can be strong or weak in different areas of nutrition, so unless we want to whip out a calculator and database every time we make food choices, a good way to cover everything is to simply eat a diverse diet.

And that goes not just for vitamins and minerals (which would be true of animal products also), but in the case of plants, a wide range of health-giving phytochemicals too:

Measuring Dietary Botanical Diversity as a Proxy for Phytochemical Exposure

Ok, I’m sold, but 30 is a lot!

It is, but you don’t have to do all 30 in your first week of focusing on this, if you’re not already accustomed to such diversity. You can add in one or two new ones each time you go shopping, and build it up.

As for “what counts”: we’re counting unprocessed or minimally-processed plants. So for example, an apple is an apple, as are dried apple slices, as is apple sauce. Any or all of those would count as 1 plant type.

Note also that we’re counting types, not totals. If you’re having apple slices with apple sauce, for some reason? That still only counts as 1.

However, while apple sauce still counts as apples (minimally processed), you cannot eat a cake and say “that’s 2 because there was wheat and sugar cane somewhere in its dim and distant history”.

Nor is your morning espresso a fruit (by virtue of coffee beans being the fruit of the plant, botanically speaking). However, it would count as 1 plant type if you eat actual coffee beans—this writer has been known to snack on such; they’re only healthy in very small portions though, because their saturated fat content is a little high.

You, however, count grains in general, as well as nuts and seeds, not just fruits and vegetables. As for herbs and spices, they count for ¼ each, except for salt, which might get lumped in with spices but is of course not a plant.

How to do it

There’s a reason we’re doing this in our Saturday Life Hacks edition. Here are some tips for getting in far more plants than you might think, a lot more easily than you might think:

  • Buy things ready-mixed. This means buying the frozen mixed veg, the frozen mixed chopped fruit, the mixed nuts, the mixed salad greens etc. This way, when you’re reaching for one pack of something, you’re getting 3–5 different plants instead of one.
  • Buy things individually, and mix them for storage. This is a more customized version of the above, but in the case of things that keep for at least a while, it can make lazy options a lot more plentiful. Suddenly, instead of rice with your salad you’re having sorghum, millet, buckwheat, and quinoa. This trick also works great for dried berries that can just be tipped into one’s morning oatmeal. Or, you know, millet, oats, rye, and barley. Suddenly, instead of 1 or 2 plants for breakfast you have maybe 7 or 8.
  • Keep a well-stocked pantry of shelf-stable items. This is good practice anyway, in case of another supply-lines shutdown like at the start of the COVID-19 pandemic. But for plant diversity, it means that if you’re making enchiladas, then instead using kidney beans because that’s what’s in the cupboard, you can raid your pantry for kidney beans, black beans, pinto beans, fava beans, etc etc. Yes, all of them; that’s a list, not a menu.
  • Shop in the discount section of the supermarket. You don’t have shop exclusively there, but swing by that area, see what plants are available for next to nothing, and buy at least one of each. Figure out what to do with it later, but the point here is that it’s a good way to get suggestions of plants that you weren’t actively looking for—and novelty is invariably a step into diversity.
  • Shop in a different store. You won’t be able to beeline the products you want on autopilot, so you’ll see other things on the way. Also, they may have things your usual store doesn’t.
  • Shop in person, not online—at least as often as is practical. This is because when shopping for groceries online, the store will tend to prioritize showing you items you’ve bought before, or similar items to those (i.e. actually the same item, just a different brand). Not good for trying new things!
  • Consider a meal kit delivery service. Because unlike online grocery shopping, this kind of delivery service will (usually) provide you with things you wouldn’t normally buy. Our sometimes-sponsor Purple Carrot is a fine option for this, but there are plenty of others too.
  • Try new recipes, especially if they have plants you don’t normally use. Make a note of the recipe, and go out of your way to get the ingredients; if it seems like a chore, reframe it as a little adventure instead. Honestly, it’s things like this that keep us young in more ways than just what polyphenols can do!
  • Hide the plants. Whether or not you like them; hide them just because it works in culinary terms. By this we mean; blend beans into that meaty sauce; thicken the soup with red lentils, blend cauliflower into the gravy. And so on.

One more “magic 30”, while we’re at it…

30g fiber per day makes a big (positive) difference to many aspects of health. Obviously, plants are where that comes from, so there’s a big degree of overlap here, but most of the tips we gave are different, so for double the effectiveness, check out:

  • Cherries vs Cranberries – 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 cherries to cranberries, we picked the cherries.

    Why?

    In terms of macros, cherries have a little more protein (but it’s not much) while cranberries have a little more fiber. Despite this, cherries have the lower glycemic index—about half that of cranberries.

    In the category of vitamins, cherries have a lot more of vitamins A, B1, B2, B3, B9, and a little more choline, while cranberries have more of vitamins B5, B6, C, E, and K. A modest win for cherries here.

    When it comes to minerals, things are more divided: cherries have more calcium, copper, iron, magnesium, phosphorus, potassium, and zinc, while cranberries have more manganese. An easy win for cherries here.

    This all adds up to a total win for cherries, but both of these fruits are great and both have their own beneficial properties (see our main features below!)

  • Why Everyone You Don’t Like Is A Narcissist

    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’ve written before about how psychiatry tends to name disorders after how they affect other people, rather than how they affect the bearer, and this is most exemplified when it comes to personality disorders. For example:

    “You have a deep insecurity about never being good enough, and you constantly mess up in your attempt to overcompensate? You may have Evil Bastard Disorder!”

    “You have a crippling fear of abandonment and that you are fundamentally unloveable, so you do all you can to try to keep people close? You must have Manipulative Bitch Disorder!”

    See also: Miss Diagnosis: Anxiety, ADHD, & Women

    Antisocial Diagnoses

    These days, it is easy to find on YouTube countless videos of how to spot a narcissist, with a list of key traits that all mysteriously describe exactly the exes of everyone in the comments.

    And these days it is mostly “narcissist”, because “psychopath” and “sociopath” have fallen out of popular favor a bit:

    • perhaps for coming across as overly sensationalized, and thus lacking credibility
    • perhaps because “Narcissistic Personality Disorder (NPD)” exists in the DSM-5 (the US’s latest “Diagnostic and Statistical Manual of Mental Disorders”), while psychopathy and sociopathy are not mentioned as existing.

    You may be wondering: what do “psychopathy” and “sociopathy” mean?

    And the answer is: they mean whatever the speaker wants them to mean. Their definitions and differences/similarities have been vigorously debated by clinicians and lay enthusiasts alike for long enough that the scientific world has pretty much given up on them and moved on.

    Stigma vs pathology

    Because of the popular media (and social media) representation of NPD, it is easy to armchair diagnose one’s relative/ex/neighbor/in-law/boss/etc as being a narcissist, because the focus is on “narcissists do these bad things that are mean to people”.

    If the focus were instead on “narcissists have cripplingly low self-esteem, and are desperate to not show weakness in a world they have learned is harsh and predatory”, then there may not be so many armchair diagnoses—or at the very least, the labels may be attached with a little more compassion, the same way we might with other mental health issues such as depression.

    Not that those with depression get an easy time of it socially either—society’s response is generally some manner of “aren’t you better yet, stop being lazy”—but at the very least, depressed people are not typically viewed with hatred.

    A quick aside: if you or someone you know is struggling with depression, here are some things that actually help:

    The Mental Health First-Aid You’ll Hopefully Never Need

    The disorder is not the problem

    Maybe your relative, ex, neighbor, etc really is clinically diagnosable as a narcissist. There are still two important things to bear in mind:

    • After centuries of diagnosing people with mental health maladies that we now know don’t exist per se (madness, hysteria, etc), and in recent decades countless revisions to the DSM and similar tomes, thank goodness we now have the final and perfect set of definitions that surely won’t be re-written in the next few years or so ← this is irony; it will absolutely be re-written numerous times yet because of course it’s still not a magically perfect descriptor of the broad spectrum of human nature
    • The disorder is not the problem; the way they treat (or have treated) you is the problem.

    For example, let’s take a key thing generally attributed to narcissists: a lack of empathy

    Now, empathy can be divided into:

    • affective empathy: the ability to feel what other people are feeling
    • cognitive empathy: the ability to intellectually understand what other people are feeling (akin to sympathy, which is the same but with the requisite of having experienced the thing in question oneself)

    A narcissist (as well as various other people without NPD) will typically have negligible affective empathy, and their cognitive empathy may be a little sluggish too.

    Sluggish = it may take them a beat longer than most people, to realize what an external signifier of emotions means, or correctly guess how something will be felt by others. This can result in gravely misspeaking (or inappropriately emoting), after failing to adequately quickly “read the room” in terms of what would be a socially appropriate response. To save face, they may then either deny/minimize the thing they just said/did, or double-down on it and go on [what for them feels like] the counterattack.

    As to why this shutting off of empathy happens: they have learned that the world is painful, and that people are sources of pain, and so—to avoid further pain—have closed themselves off to that, often at a very early age. This will also apply to themselves; narcissists typically have negligible self-empathy too, which is why they will commonly make self-destructive decisions, even while trying to put themselves first.

    Important note on how this impacts other people: the “Golden Rule” of “treat others as you would wish to be treated” becomes intangible, as they have no more knowledge of their own emotional needs than they do of anyone else’s, so cannot make that comparison.

    Consider: if instead of being blind to empathy, they were colorblind… You would probably not berate them for buying green apples when you asked for red. They were simply incapable of seeing that, and consequently made a mistake. So it is when it’s a part of the brain that’s not working normally.

    So… Since the behavior does adversely affect other people, what can be done about it? Even if “hate them for it and call for their eradication from the face of the Earth” is not a reasonable (or compassionate) option, what is?

    Take the bull by the horns

    Above all, and despite all appearances, a narcissist’s deepest desire is simply to be accepted as good enough. If you throw them a life-ring in that regard, they will generally take it.

    So, communicate (gently, because a perceived attack will trigger defensiveness instead, and possibly a counterattack, neither of which are useful to anyone) what behavior is causing a problem and why, and ask them to do an alternative thing instead.

    And, this is important, the alternative thing has to be something they are capable of doing. Not merely something that you feel they should be capable of doing, but that they are actually capable of doing.

    • So not: “be a bit more sensitive!” because that is like asking the colorblind person to “be a bit more observant about colors”; they are simply not capable of it and it is folly to expect it of them, because no matter how hard they try, they can’t.
    • But rather: “it upsets me when you joke about xyz; I know that probably doesn’t make sense to you and that’s ok, it doesn’t have to. I am asking, however, if you will please simply refrain from joking about xyz. Would you do that for me?”

    Presented with such, it’s much more likely that the narcissist will drop their previous attempt to be good enough (by joking, because everyone loves someone with a sense of humor, right?) for a new, different attempt to be good enough (by showing “behold, look, I am a good person and doing the thing you asked, of which I am capable”).

    That’s just one example, but the same methodology can be applied to most things.

    For tricks pertaining to how to communicate such things without causing undue resistance, see:

  • Habits of a Happy Brain – by Dr. Loretta Graziano Breuning

    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 lots of books on “happy chemicals” and “how to retrain your brain”, so what makes this one different?

    Firstly, it focuses on four “happy chemicals”, not just one:

    • Serotonin
    • Dopamine
    • Oxytocin
    • Endorphins

    It also looks at the role of cortisol, and how it caps off each of those just a little bit, to keep us just a little malcontent.

    Behavioral psychology tends to focus most on dopamine, while prescription pharmaceuticals for happiness (i.e., most antidepressants) tend to focus on serotonin. Here, Dr. Breuning helps us understand the complex interplay of all of the aforementioned chemicals.

    She also clears up many misconceptions, since a lot of people misattribute the functions of each of these.

    Common examples include “I’m doing this for the serotonin!” when the activity is dopaminergic not serotoninergic, or considering dopamine “the love molecule” when oxytocin, or even something else like phenylethylamine would be more appropriate.

    The above may seem like academic quibbles and not something of practical use, but if we want to biohack our brains, we need to do better than the equivalent of a chef who doesn’t know the difference between salt and sugar.

    Where things are of less practical use, she tends to skip over or at least streamline them. For example, she doesn’t really discuss the role of post-dopamine prolactin in men—but the discussion of post-happiness cortisol covers the same ground anyway, for practical purposes.

    Dr. Breuning also looks at where our evolved neurochemical responses go wrong, and lays out guidelines for such challenges as overcoming addiction, or embracing delayed gratification.

    Bottom line: this book is a great user-manual for the brain. If you’d like to be happier and more effective with fewer bad habits, this is the book for you.

  • Gut-Healthy Spaghetti Chermoula

    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.

    Chermoula is a Maghreb relish/marinade (it’s used for both purposes); it’s a little like chimichurri but with distinctly N. African flavors. The gut-healthiness starts there (it’s easy to forget that olives—unless fresh—are a fermented food full of probiotic Lactobacillus sp. and thus great for the gut even beyond their fiber content), and continues in the feta, the vegetables, and the wholewheat nature of the pasta. The dish can be enjoyed at any time, but it’s perfect for warm summer evenings—perhaps dining outside, if you’ve place for that.

    You will need

    • 9oz wholewheat spaghetti (plus low-sodium salt for its water)
    • 10oz broccoli, cut into small florets
    • 3oz cilantro (unless you have the soap gene)
    • 3oz parsley (whether or not you included the cilantro)
    • 3oz green olives, pitted, rinsed
    • 1 lemon, pickled, rinsed
    • 1 bulb garlic
    • 3 tbsp pistachios, shelled
    • 2 tbsp mixed seeds
    • 1 tsp cumin
    • 1 tsp chili flakes
    • ½ cup extra virgin olive oil
    • For the garnish: 3oz feta (or plant-based equivalent), crumbled, 3oz sun-dried tomatoes, diced, 1 tsp cracked black pepper

    Note: why are we rinsing the things? It’s because while picked foods are great for the gut, the sodium can add up, so there’s no need to bring extra brine with them too. By doing it this way, there’ll be just the right amount for flavor, without overdoing it.

    Method

    (we suggest you read everything at least once before doing anything)

    1) Cook the spaghetti as you normally would, but when it’s a minute or two from being done, add the broccoli in with it. When it’s done, drain and rinse thoroughly to get rid of excess starch and salt, and also because cooling it even temporarily (as in this case) lowers its glycemic index.

    2) Put the rest of the ingredients into a food processor (except the olive oil and the garnish), and blitz thoroughly until no large coarse bits remain. When that’s done, add the olive oil, and pulse it a few times to combine. We didn’t add the olive oil previously, because blending it so thoroughly in that state would have aerated it in a way we don’t want.

    3) Put ⅔ of the chermoula you just made into the pan you used for cooking the spaghetti, and set it over a medium heat. When it starts bubbling, return the spaghetti and broccoli to the pan, mixing gently but thoroughly. If the pasta threatens to stick, you can add a little more chermoula, but go easy on it. Any leftover chermoula that you didn’t use today, can be kept in the fridge and used later as a pesto.

    4) Serve! Add the garnish as you do.

    Enjoy!

    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. Anil Rajani has advice on restoring/retaining youthfulness. Two out of three of the sections are on skincare specifically, which may seem a vanity, but it’s also worth remembering that our skin is a very large and significant organ, and makes a big difference for the rest of our physical health, as well as our mental health. So, it’s worthwhile to look after it:

    The recommendations

    Daily: meditation practice

    Meditation reduces stress, which reduction in turn protects telomere length, slowing the overall aging process in every living cell of the body.

    Weekly: skincare basics

    Dr. Rajani recommends a combination of retinol and glycolic acid. The former to accelerate cell turnover, stimulate collagen production, and reduce wrinkles; the latter, to exfoliate dead cells, allowing the retinol to do its job more effectively.

    We at 10almonds would like to add: wearing sunscreen with SPF50 is a very good thing to do on any day that your phone’s weather app says the UV index is “moderate” or higher.

    Monthly: skincare extras

    Here are the real luxuries; spa visits, microneedling (stimulates collagen production), and non-ablative laser therapy. He recommends creating a home spa if possible for monthly skincare treatments, investing in high-quality devices for long-term benefits.

  • The Sweet Truth About 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.

    There’s A Lot Of Confusion About Diabetes!

    For those readers who are not diabetic, nor have a loved one who is diabetic, nor any other pressing reason to know these things, first a quick 101 rundown of some things to understand the rest of today’s main feature:

    • Blood sugar levels: how much sugar is in the blood, measured in mg/dL or mmol/L
    • Hyperglycemia or “hyper” for short: too much sugar in the blood
    • Hypoglycemia or “hypo” for short: too little sugar in the blood
    • Insulin: a hormone that acts as a gatekeeper to allow sugar to pass, or not pass, into various parts of the body
    • Type 1 diabetes (sometimes capitalized, and/or abbreviated to “T1D”) is an autoimmune disorder that prevents the pancreas from being able to supply the body with insulin. This means that taking insulin consistently is necessary for life.
    • Type 2 diabetes is a matter of insulin resistance. The pancreas produces plenty of insulin, but the body has become desensitized to it, so it doesn’t work properly. Taking extra insulin may sometimes be necessary, but for many people, it can be controlled by means of a careful diet and other lifestyle factors.

    With that in mind, on to some very popular myths…

    Diabetes is caused by having too much sugar

    While sugar is not exactly a health food, it’s not the villain of this story either.

    • Type 1 diabetes has a genetic basis, triggered by epigenetic factors unrelated to sugar.
    • Type 2 diabetes comes from a cluster of risk factors which, together, can cause a person to go through pre-diabetes and acquire type 2 diabetes.
      • Those risk factors include:
        • A genetic predisposition
        • A large waist circumference
          • (this is more relevant than BMI or body fat percentage)
        • High blood pressure
        • A sedentary lifestyle
        • Age (the risk starts rising at 35, rises sharply at 45, and continues upwards with increasing age)

    Read more: Risk Factors for Type 2 Diabetes

    Diabetics can’t have sugar

    While it’s true that diabetics must be careful about sugar (and carbs in general), it’s not to say that they can’t have them… just: be mindful and intentional about it.

    • Type 1 diabetics will need to carb-count in order to take the appropriate insulin bolus. Otherwise, too little insulin will result in hyperglycemia, or too much insulin will result in hypoglycemia.
    • Type 2 diabetics will often be able to manage their blood sugar levels with diet alone, and slow-release carbs will make this easier.

    In either case, having quick release sugars will increase blood sugar levels (what a surprise), and sometimes (such as when experiencing a hypo), that’s what’s needed.

    Also, when it comes to sugar, a word on fruit:

    Not all fruits are equal, and some fruits can help maintain stable blood sugar levels! Read all about it:

    Fruit Intake to Prevent and Control Hypertension and Diabetes

    Artificial sweeteners are must-haves for diabetics

    Whereas sugar is a known quantity to the careful diabetic, some artificial sweeteners can impact insulin sensitivity, causing blood sugars to behave in unexpected ways. See for example:

    The Impact of Artificial Sweeteners on Body Weight Control and Glucose Homeostasis

    If a diabetic person is hyper, they should exercise to bring their blood sugar levels down

    Be careful with this!

    • In the case of type 2 diabetes, it may (or may not) help, as the extra sugar may be used up.
    • Type 1 diabetes, however, has a crucial difference. Because the pancreas isn’t making insulin, a hyper (above a certain level, anyway) means more insulin is needed. Exercising could do more harm than good, as unlike in type 2 diabetes, the body has no way to use that extra sugar, without the insulin to facilitate it. Exercising will just pump the syrupy hyperglycemic blood around the body, potentially causing damage as it goes (all without actually being able to use it).

    There are other ways this can be managed that are outside of the scope of this newsletter, but “be careful” is rarely a bad approach.
