Eating For Energy (In Ways That Actually Work)

Snacks & Hacks: The Real Energy Boosters

Declining energy levels are a common complaint of people getting older, and this specific kind of “getting older” is starting earlier and earlier (even Gen-Z are already getting in line for this one). For people of all ages, however, diet is often a large part of the issue.

The problem:

It can sometimes seem, when it comes to food and energy levels, that we have a choice:

  • Don’t eat (energy levels decline)
  • Eat quick-release energy snacks (energy spikes and crashes)
  • Eat slow-release energy meals (oh hi, post-dinner slump)

But, this minefield can be avoided! Advice follows…

Skip the quasi-injectables

Anything the supermarket recommends for rapid energy can be immediately thrown out (e.g. sugary energy drinks, glucose tablets, and the like).

Same goes for candy of most sorts (if the first ingredient is sugar, it’s not good for your energy levels).

Unless you are diabetic and need an emergency option to keep with you in case of a hypo, the above things have no place on a healthy shopping list.

Aside from that, if you have been leaning on these heavily, you might want to check out yesterday’s main feature:

The Not-So-Sweet Science Of Sugar Addiction

…and if your knee-jerk response is “I’m not addicted; I just enjoy…” then ok, test that! Skip it for this month.

  • If you succeed, you’ll be in better health.
  • If you don’t, you’ll be aware of something that might benefit from more attention.

Fruit and nuts are your best friends

Unless you are allergic, in which case, obviously skip your allergen(s).

But for most of us, we were born to eat fruit and nuts. Literally, those two things are amongst the oldest and most well-established parts of human diet, which means that our bodies have had a very long time to evolve the perfect fruit-and-nut-enjoying abilities, and reap the nutritional benefits.

Nuts are high in fat (healthy fats) and that fat is a great source of energy’s easy for the body to get from the food, and/but doesn’t result in blood sugar spikes (and thus crashes) because, well, it’s not a sugar.

See also: Why You Should Diversify Your Nuts

Fruit is high in sugars, and/but high in fiber that slows the absorption into a nice gentle curve, and also contains highly bioavailable vitamins to perk you up and polyphenols to take care of your long-term health too.

Be warned though: fruit juice does not work the same as actual fruit; because the fiber has been stripped and it’s a liquid, those sugars are zipping straight in exactly the same as a sugary energy drink.

Slow release carbs yes, but…

Eating a bowl of wholegrain pasta is great if you don’t have to do anything much immediately afterwards, but it won’t brighten your immediately available energy much—on the contrary, energy will be being used for digestion for a while.

So if you want to eat slow-release carbs, make it a smaller portion of something more-nutrient dense, like oats or lentils. This way, the metabolic load will be smaller (because the portion was smaller) but the higher protein content will prompt satiety sooner (so you addressed your hunger with a smaller portion) and the iron and B vitamins will be good for your energy too.

Animal, vegetable, or mineral?

At the mention of iron and B vitamins, you might be thinking about various animal products that might work too.

If you are vegetarian or vegan: stick to that; it’s what your gut microbiome is used to now, and putting an animal product in will likely make you feel ill.

If you have them in your diet already, here’s a quick rundown of how broad categories of animal product work (or not) for energy:

  • Meat: nope. Well, the fat, if applicable, will give you some energy, but less than you need just to digest the meat. This, by the way, is a likely part of why the paleo diet is good for short term weight loss. But it’s not very healthy.
  • Fish: healthier than the above, but for energy purposes, just the same.
  • Dairy: high-fat dairy, such as cream and butter, are good sources of quick energy. Be aware if they contain lactose though, that this is a sugar and can be back to spiking blood sugars.
    • As an aside for diabetics: this is why milk can be quite good for correcting a hypo: the lactose provides immediate sugar, and the fat keeps it more balanced afterwards
  • Eggs: again the fat is a good source of quick energy, and the protein is easier to digest than that of meat (after all, egg protein is literally made to be consumed by an embryo, while meat protein is made to be a functional muscle of an animal), so the metabolic load isn’t too strenuous. Assuming you’re doing a moderate consumption (under 3 eggs per day) and not Sylvester Stallone-style 12-egg smoothies, you’re good to go.

Hydration considerations

Lastly, food that is hydrating will be more energizing than food that is not, so how does your snack/meal rank on a scale of watermelon to saltines?

You may be thinking: “But you said to eat nuts! They’re not hydrating at all!”, in which case, indeed, drink water with them, or better yet, enjoy them alongside fruit (hydration from food is better than hydration from drinking water).

And as for those saltines? Salt is not your friend (unless you are low on sodium, because then that can sap your energy)

How to tell if you are low on sodium: put a little bit (e.g. ¼ tsp) of salt into a teaspoon and taste it; does it taste unpleasantly salty? If not, you were low on sodium. Have a little more at five minute intervals, until it tastes unpleasantly salty. Alternatively have a healthy snack that nonetheless contains a little salt.

If you otherwise eat salty food as an energy-giving snack, you risk becoming dehydrated and bloated, neither of which are energizing conditions.

Dehydrated and bloated at once? Yes, the two often come together, even though it usually doesn’t feel like it. Basically, if we consume too much salty food, our homeostatic system goes into overdrive to try to fix it, borrows a portion of our body’s water reserves to save us from the salt, and leaves us dehydrated, bloated, and sluggish.

  • Fennel vs Artichoke – 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 fennel to artichoke, we picked the artichoke.

    Why?

    Both are great! But artichoke wins on nutritional density.

    In terms of macros, artichoke has more protein and more fiber, for only slightly more carbs.

    Vitamins are another win for artichoke, boasting more of vitamins B1, B2, B3, B5, B6, B9, and choline. Meanwhile, fennel has more of vitamins A, E, and K, which is also very respectable but does allow artichoke a 6:3 lead.

    In the category of minerals, artichoke has a lot more copper, iron, magnesium, manganese, and phosphorus, while fennel has a little more calcium, potassium, and selenium.

    One other relevant factor is that fennel is a moderate appetite suppressant, which may be good or bad depending on your food-related goals.

    All in all though, we say the artichoke wins by virtue of its greater abundance of nutrients!

  • Which Plant Milk?

    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.

    Plant-based milks—what’s best?

    You asked us to look at some popular plant milks and their health properties, and we said we’d do a main feature, so here it is!

    We’ll also give a quick nod to environmental considerations at the end too (they might not be quite what you expect!). That said, as a health and productivity newsletter, we’ll be focusing on the health benefits.

    While we can give a broad overview, please note that individual brands may vary, especially in two important ways:

    • Pro: many (most?) brands of plant milks fortify their products with extra vitamins and minerals, especially vitamin D and calcium.
    • Con: some brands also add sugar.

    So, by all means use this guide to learn about the different plants’ properties, and/but still do check labels later.

    Alternatively, consider making your own!

    • Pros: no added sugar + cheaper
    • Cons: no added vitamins and minerals + some equipment required

    Almond milk

    Almond milk is low in carbs and thus good for a carb-controlled diet. It’s also high in vitamin E and a collection of minerals.

    Oat milk

    Oats are one of the healthiest “staple foods” around, and while drinking oat milk doesn’t convey all the benefits, it does a lot. It also has one of the highest soluble fiber contents of any milk, which is good for reducing LDL (bad) cholesterol levels.

    See for example: Consumption of oat milk for 5 weeks lowers serum cholesterol and LDL cholesterol in free-living men with moderate hypercholesterolemia

    Coconut milk

    Coconut has a higher fat content than most plant milks, but also contains medium-chain triglycerides (MCTs). These raise HDL (good) cholesterol levels.

    Read the study: How well do plant based alternatives fare nutritionally compared to cow’s milk?

    Hemp milk

    Being made from hemp seeds that contain a lot of protein and healthy fats (including omega-3 and omega-6), hemp milk packs a nutritious punch. It’s carb-free. It’s also THC-free, in case you were wondering, which means no, it does not have psychoactive effects.

    Pea milk

    It’s very high in protein, and contains an array of vitamins and minerals. It’s not very popular yet, so there isn’t as much research about it. This 2021 study found that it had the nutritional profile the closest to cow’s milk (beating soy by a narrow margin) and praised it as a good alternative for those with a soy allergy.

    This is Research Review Monday so we try to stick to pure science, but for your interest… here’s an interesting pop-science article (ostensibly in affiliation with the pea milk brand, Ripple) about the nutritional qualities of their pea milk specifically, which uses particularly nutrient-dense yellow peas, plus some extra vitamin and mineral fortifications:

    Read: Ripple Milk: 6 Reasons Why You Should Try Pea Milk

    Soy milk

    Perhaps the most popular plant milk, and certainly usually the cheapest in stores. It’s high in protein, similar to cow’s milk. In fact, nutritionally, it’s one of the closest to cow’s milk without involving cows as a middleman. (Did you know three quarters of all soy in the world is grown to feed to livestock, not humans? Now you do).

    And no, gentlemen-readers, it won’t have any feminizing effects. The human body can’t use the plant estrogens in soy for that. It does give some isoflavone benefits though, which are broadly good for everyone’s health. See for example this research review with 439 sources of its own:

    Read: Soy and Health Update: Evaluation of the Clinical and Epidemiologic Literature

    Quick note on flavor: nut milks have the flavor of the nut they were made from. Coconut milk tastes of coconut. The other milks listed above don’t have much of a flavor—which in many cases may be what you want.

    Note on environmental considerations:

    A lot of us try to be as socially responsible as reasonably possible in our choices, so this may be an influencing factor. In a nutshell:

    • Oats and Soy are generally grown as vast monocrops, and these are bad for the environment
      • They are still better for the environment than cow’s milk though, as for example most soy is grown to feed to cows, not humans. So including cows in the process means four times as much monocrop farming, plus adds several other environmental issues that are beyond the scope of this newsletter.
    • Almonds are particularly resource-intensive when it comes to water use.
      • Still nowhere near as much as cows, though.
    • Peas are grown in places that naturally have very high rainfall, so are a good option here. Same generally goes for rice, which didn’t make the cut today. (Nor did hazelnuts, sorry—we can only include so much!)
    • Hemp is by far and away the most environmentally friendly, assuming it is grown in a climate naturally conducive to such.
    • Making plant milk at home is usually most environmentally friendly, depending on where your ingredients came from.
    • Literally any plant milk is much more environmentally friendly than cow’s milk.

  • The Fast-Mimicking Diet

    Live, Fast, Live Long

    This is Dr. Valter Longo. He’s a biogerontologist and cell biologist, whose work has focused on fasting and nutrient response genes, and how we can leverage them against diseases and aging in general.

    We reviewed his book recently:

    The Longevity Diet: Discover The New Science To Slow Aging, Fight Disease, And Manage Your Weight – by Dr. Valter Longo

    What does he want us to know?

    What to eat

    Dr. Longo recommends a mostly plant-based diet (especially vegetables, whole grains, and legumes), but also having some fish. The bulk of our dietary fats, however, he says are best coming from olive oil and nuts.

    He also advises aiming for nutritional density of vitamins and minerals in our diet, and/but supplementing with a multivitamin once every few days to cover any gaps.

    If in doubt choosing between plant-based whole foods, he recommends that we choose those our ancestors will have eaten.

    Read more: Longevity Diet For Adults

    When to eat

    Dr. Longo recommends time-restricted eating within a 12-hour window per day.

    See also: Intermittent Fasting: We Sort The Science From The Hype

    However, he also recommends (additionally or separately; it’s up to us; additionally is better but the point is it still has excellent benefits separately too) his “fast-mimicking diet” (FMD), which involves eating according to what we said in “What to eat”, but restricting it to 750 kcal per day, 5 days in a row, but not necessarily 5 days per week.

    For example, the following was a 3-month study that involved doing this for only one 5-day cycle per month:

    ❝Three FMD cycles reduced body weight, trunk, and total body fat; lowered blood pressure; and decreased insulin-like growth factor 1 (IGF-1). No serious adverse effects were reported.

    A post hoc analysis of subjects from both FMD arms showed that body mass index, blood pressure, fasting glucose, IGF-1, triglycerides, total and low-density lipoprotein cholesterol, and C-reactive protein were more beneficially affected in participants at risk for disease than in subjects who were not at risk.

    Thus, cycles of a 5-day FMD are safe, feasible, and effective in reducing markers/risk factors for aging and age-related diseases.❞

    Note: the introduction mentions FMD in mice, but this is just referencing previous studies. This study is about FMD in humans!

    Curiosity Kills The Neurodegeneration

    Of the seven things that Leonardo da Vinci considered most important for developing and maintaining the mind, number one on his list was curiosity, and we’re going to be focussing on that today.

    In case you are curious about what seven things made Leonardo’s* list, they were:

    1. Curiosità: an insatiably curious approach to life and an unrelenting quest for continuous learning
    2. Dimostrazione: a commitment to test knowledge through experience, persistence, and a willingness to learn from mistakes
    3. Sensazione: the continual refinement of the senses, especially sight, as a means to enliven experience
    4. Sfumato: (lit: “gone up in smoke”) a willingness to embrace ambiguity, paradox, and uncertainty
    5. Arte/Scienza: the curated balance of art and science, imagination and logic
    6. Corporalità: the cultivation of physical grace, ambidexterity, and fitness
    7. Connessione: a recognition of and appreciation for the interconnectedness of phenomena (systems-based thinking)

    *In case you are curious why we wrote “Leonardo” and not “da Vinci” as per our usual convention of shortening names to last names, da Vinci is not technically a name, in much the same way as “of Nazareth” was not a name.

    You can read more about all 7 of these in a book that we’ve reviewed previously:

    How to Think Like Leonardo da Vinci: Seven Steps to Genius Every Day – by Michael J. Gelb

    But for now, let’s take on “curiosity”!

    If you need an extra reason to focus on growing and nurturing your curiosity, it was also #1 of Dr. Daniel Levitin’s list of…

    The Five Keys Of Aging Healthily

    …and that’s from a modern-day neuroscientist whose research focuses on aging, the brain, health, productivity, and creativity.

    But how do we foster curiosity in the age of Google?

    Curiosity is like a muscle: use it or lose it

    While it’s true that many things can be Googled to satisfy one’s curiosity in an instant…

    • do you? It’s only useful if you do use it
    • is the top result on Google reliable?
    • there are many things that aren’t available there

    In short: douse “fast food information” sources, but don’t rely on them! Not just for the sake of having correct information, but also: for the actual brain benefits which is what we are aiming for here with today’s article.

    If you want the best brain benefits, dive in, and go deep

    Here at 10almonds we often present superficial information, with links to deeper information (often: scholarly articles). We do this because a) there’s only so much we can fit in our articles and b) we know you only have so much time available, and/but may choose to dive deeper.

    Think of it in layers, e.g:

    • Collagen is good for joints and bones
    • Collagen is a protein made of these amino acids that also requires these vitamins and minerals to be present in order to formulate it
    • Those amino acids are needed in these quantities, of which this particular one is usually the weakest link that might need supplementing, and those vitamins and minerals need to be within this period of time, but not these ones at the exact same time, or else it will disrupt the process of collagen synthesis

    (in case you’re curious, we covered this here and here and offered a very good, very in-depth book about it here)

    Now, this doesn’t mean that to have a healthy brain you need to have the equivalent knowledge of an anatomy & physiology degree, but it is good to have that level of curiosity in at least some areas of your life—and the more, the better.

    Top tips for developing a habit of curiosity

    As you probably know, most of our endeavors as humans go best when they are habits:

    How To Really Pick Up (And Keep!) Those Habits

    And as for specifically building a habit of curiosity:

    1. Make a deal with yourself that when someone is excited to tell you what they know about something (no matter whether it is your grandkid, or the socially awkward nerd at a party, or whoever), listen and learn, no matter the topic.
    2. Learn at least one language other than your native language (presumably English for most of our readers). Not only does learning a language convey a lot of brain benefits of its own, but also, it is almost impossible to separate language learning from cultural learning, and so you will learn a lot about another culture too, and have whole new worlds opened up to you. Again, more is better, but one second language is already a lot better than none.
    3. Make a regular habit of going to your local library, and picking out a non-fiction book to take home and read. This has an advantage over a bookshop, by the way (and not just that the library is free): since library books must be returned, you will keep going back, and build a habit of taking out books.
    4. Pick a skill that you’d like to make into a fully-fledged hobby, and commit to continually learning as much about it as you can. We already covered language-learning above, but others might include: gardening (perhaps a specific kind), cooking (perhaps a specific kind), needlecraft (perhaps a specific kind), dance (perhaps a specific kind). You could learn a musical instrument. Or it could be something very directly useful, like learning to be a first responder in case of emergencies, and committing to continually learning more about it (because there is always more to learn).

    And when it comes to the above choices… Pick things that excite you, regardless of how practical or not they are. Because that stimulation that keeps on driving you? That’s what keeps your brain active, healthy, and sharp.

    Enjoy!

  • Move over, COVID and Flu! We Have “Hybrid Viruses” To Contend With Now

    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.

    Move over, COVID and Flu! We have “hybrid viruses” to contend with now

    COVID and influenza viruses can be serious, of course, so let’s be clear up front that we’re not being dismissive of those. But, most people are hearing a lot about them, whereas respiratory syncytial virus (RSV) has flown under a lot of radars.

    Simply put, until recently it hasn’t been considered much of a threat except to the young, the old, or people with other respiratory illnesses. Only these days, the prevalence of “other respiratory illnesses” is a lot higher than it used to be!

    It’s not just a comorbidity

    It’s easy to think “well of course if you have more than one illness at once, especially similar ones, that’s going to suck” but it’s a bit more than that; it produces newer, more interesting, hybrid viruses. Here’s a research paper from last year’s “flu season”:

    Coinfection by influenza A virus and respiratory syncytial virus produces hybrid virus particles

    Best to be aware of this if you’re in the “older” age-range

    It’s not just that the older we are, the more likely we are to get it. Critically, the older we are, the more likely we are to be hospitalized by it.

    And..the older we are, the less likely we are to come back from hospital if hospitalized by it.

    Some years back, the intensive care and mortality rates for people over the age of 65 were 8% and 7%, respectively:

    Respiratory syncytial virus infection in elderly and high-risk adults

    …but a new study this year has found the rates like to be 2.2x that, i.e. 15% intensive care rate and 18% mortality, respectively:

    Here are some hot-off-the-press news articles on the topic:

    And as for what to do…

    Same general advice as for COVID and Flu, just, ever-more important:

    • Get any worrying symptoms checked out quickly
    • Mask up when appropriate
    • Get your shots as appropriate

  • Exercise with Type 1 Diabetes – by Ginger Vieira

    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.

    If you or a loved one has Type 1 Diabetes, you’ll know that exercise can be especially frustrating…

    • If you don’t do it, you risk weight gain and eventual insulin resistance.
    • If you do it, you risk dangerous hypos, or perhaps hypers if you took off your pump or skipped a bolus.

    Unfortunately, the popular medical advice is “well, just do your best”.

    Ginger Vieira is Type 1 Diabetic, and writes with 20+ experience of managing her diabetes while being a keen exerciser. As T1D folks out there will also know, comorbidities are very common; in her case, fibromyalgia was the biggest additional blow to her ability to exercise, along with an underactive thyroid. So when it comes to dealing with the practical nuts and bolts of things, she (while herself observing she’s not a doctor, let alone your doctor) has a lot more practical knowledge than an endocrinologist (without diabetes) behind a desk.

    Speaking of nuts and bolts, this book isn’t a pep talk.

    It has a bit of that in, but most of it is really practical information, e.g: using fasted exercise (4 hours from last meal+bolus) to prevent hypos, counterintuitive as that may seemthe key is that timing a workout for when you have the least amount of fast-acting insulin in your body means your body can’t easily use your blood sugars for energy, and draws from your fat reserves instead… Win/Win!

    That’s just one quick tip because this is a 1-minute review, but Vieira gives:

    • whole chapters, with example datasets (real numbers)
    • tech-specific advice, e.g. pump, injection, etc
    • insulin-specific advice, e.g. fast vs slow, and adjustments to each in the context of exercise
    • timing advice re meal/bolus/exercise for different insulins and techs
    • blood-sugar management advice for different exercise types (aerobic/anaerobic, sprint/endurance, etc)

    …and lots more that we don’t have room to mention here

    Basically… If you or a loved one has T1D, we really recommend this book!
