Our Verdict

When comparing parsley to spinach, we picked the parsley.

Why?

First of all, writer’s anecdote: today’s choice brought to you by a real decision here in my household! You see, a certain dish I sometimes prepare (it’s just a wrap-based dish, nothing fancy) requires a greenery component, and historically I’ve used kale or spinach. Of those two, I prefer kale while my son, who lives (and dines) with me, prefers spinach. However, we both like parsley equally, so I’m going to use that today. But I was curious about how it performed nutritionally, hence today’s comparison!

Ok, now for the stats…

In terms of macros, the only difference is that parsley has more fiber and carbs, for an approximately equal glycemic index, so we’ll go with the one with the highest total fiber, which is parsley.

In the category of vitamins, parsley has more of vitamins B3, B5, B7, B9, C, and K, while spinach has more of vitamins A, B2, B6, E, and choline. So, a marginal 6:5 win for parsley (and in the margins of difference are also in parsley’s favor, for example parsley has 13x the vitamin C, and 2x or 3x the other vitamins it won with, while spinach boasts 2x for some vitamins, and only 1.2x or 1.5x the others).

When it comes to minerals, parsley has more iron, phosphorus, potassium, and zinc, while spinach has more copper, magnesium, manganese, and selenium. So, a 4:4 tie on these.

In terms of phytochemicals, parsley has a much higher polyphenol content (that’s good) while spinach has a much higher oxalate content (that’s neutral for most people, but bad if you have certain kidney problems). So, another win for parsley.

Adding up the sections makes a clear overall win for parsley, but by all means enjoy either or both, unless you are avoiding oxalates, in which case, the oxalates in spinach can be reduced by cooking, but honestly, for most dishes you might as well just pick a different greens option (like parsley, or collard greens if you want something closer to the culinary experience of eating spinach).

  • How Useful Is Hydrotherapy?

    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.

    Hyyyyyyydromatic…

    Hydrotherapy is a very broad term, and refers to any (external) use of water as part of a physical therapy. Today we’re going to look at some of the top ways this can be beneficial—maybe you’ll know them all already, but maybe there’s something you hadn’t thought about or done decently; let’s find out!

    Notwithstanding the vague nature of the umbrella term, some brave researchers have done a lot of work to bring us lots of information about what works and what doesn’t, so we’ll be using this to guide us today. For example:

    Scientific Evidence-Based Effects of Hydrotherapy on Various Systems of the Body

    Swimming (and similar)

    An obvious one, this can for most people be a very good full-body exercise, that’s exactly as strenuous (or not) as you want/need it to be.

    It can be cardio, it can be resistance, it can be endurance, it can be high-intensity interval training, it can be mobility work, it can be just support for an aching body that gets to enjoy being in the closest to zero-gravity we can get without being in freefall or in space.

    See also: How To Do HIIT (Without Wrecking Your Body)

    Depending on what’s available for you locally (pool with a shallow area, for example), it can also be a place to do some exercises normally performed on land, but with your weight being partially supported (and as a counterpoint, a little resistance added to movement), and no meaningful risk of falling.

    Tip: check out your local facilities, to see if they offer water aerobics classes; because the water necessitates slow movement, this can look a lot like tai chi to watch, but it’s great for mobility and balance.

    Water circuit therapy

    This isn’t circuit training! Rather, it’s a mixture of thermo- and cryotherapy, that is to say, alternating warm and cold water immersion. This can also be interspersed with the use of a sauna, of course.

    See also:

    this last one is about thermal shock-mediated hormesis, which sounds drastic, but it’s what we’re doing here with the hot and cold, and it’s good for most people!

    Pain relief

    Most of the research for this has to do with childbirth pain rather than, for example, back pain, but the science is promising:

    A systematic meta-thematic synthesis to examine the views and experiences of women following water immersion during labour and waterbirth

    Post-exercise recovery

    It can be tempting to sink into a hot bath, or at least enjoy a good hot shower, after strenuous exercise. But does it help recovery too? The answer is probably yes:

  • Carrots vs Red Cabbage – 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 carrots to red cabbage, we picked the red cabbage.

    Why?

    It’s very close!

    In terms of macros, these two vegetables are pretty much equal on all metrics. By official numbers, carrots have a tiny bit more fiber and red cabbage has a tiny bit more protein, but realistically, the difference are so small that they’re within the margin of variation (i.e. while we look at official average values, in reality one plant’s figures will differ very slightly from another’s; it could depend on what the soil was like or which plant got more sun, etc). So, a tie here.

    In the category of vitamins, carrots have more of vitamins A, B3, B5, and E, while red cabbage has more of vitamins B2, B6, C, K, and choline. So, both have their merits, but red cabbage enjoys a measurable marginal victory here.

    Looking at minerals, carrots have more copper, phosphorus, and potassium, while red cabbage has more calcium, iron, magnesium, manganese, and selenium. So, another marginal win for red cabbage here.

    When it comes to phytochemicals, they’re about equal on polyphenols and other relevant phytonutrients not otherwise mentioned above.

    Adding up the sections makes for a win for red cabbage, but it was close, and carrots are certainly great too. Enjoy either or both; diversity is good!

  • 154 million lives saved in 50 years: 5 charts on the global success of vaccines

    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 know vaccines have been a miracle for public health. Now, new research led by the World Health Organization has found vaccines have saved an estimated 154 million lives in the past 50 years from 14 different diseases. Most of these have been children under five, and around two-thirds children under one year old.

    In 1974 the World Health Assembly launched the Expanded Programme on Immunization with the goal to vaccinate all children against diphtheria, tetanus, pertussis (whooping cough), measles, polio, tuberculosis and smallpox by 1990. The program was subsequently expanded to include several other diseases.

    The modelling, marking 50 years since this program was established, shows a child aged under ten has about a 40% greater chance of living until their next birthday, compared to if we didn’t have vaccines. And these positive effects can be seen well into adult life. A 50-year-old has a 16% greater chance of celebrating their next birthday thanks to vaccines.

    What the study did

    The researchers developed mathematical and statistical models which took in vaccine coverage data and population numbers from 194 countries for the years 1974–2024. Not all diseases were included (for example smallpox, which was eradicated in 1980, was left out).

    The analysis includes vaccines for 14 diseases, with 11 of these included in the Expanded Programme on Immunization. For some countries, additional vaccines such as Japanese encephalitis, meningitis A and yellow fever were included, as these diseases contribute to major disease burden in certain settings.

    The models were used to simulate how diseases would have spread from 1974 to now, as vaccines were introduced, for each country and age group, incorporating data on increasing vaccine coverage over time.

    Children are the greatest beneficiaries of vaccines

    Since 1974, the rates of deaths in children before their first birthday has more than halved. The researchers calculated almost 40% of this reduction is due to vaccines.

    The effects have been greatest for children born in the 1980s because of the intensive efforts made globally to reduce the burden of diseases like measles, polio and whooping cough.

    Some 60% of the 154 million lives saved would have been lives lost to measles. This is likely due to its ability to spread rapidly. One person with measles can spread the infection to 12–18 people.

    The study also found some variation across different parts of the world. For example, vaccination programs have had a much greater impact on the probability of children living longer across low- and middle-income countries and settings with weaker health systems such as the eastern Mediterranean and African regions. These results highlight the important role vaccines play in promoting health equity.

    Vaccine success is not assured

    Low or declining vaccine coverage can lead to epidemics which can devastate communities and overwhelm health systems.

    Notably, the COVID pandemic saw an overall decline in measles vaccine coverage, with 86% of children having received their first dose in 2019 to 83% in 2022. This is concerning because very high levels of vaccination coverage (more than 95%) are required to achieve herd immunity against measles.

    In Australia, the coverage for childhood vaccines, including measles, mumps and rubella, has declined compared to before the pandemic.

    This study is a reminder of why we need to continue to vaccinate – not just against measles, but against all diseases we have safe and effective vaccines for.

    The results of this research don’t tell us the full story about the impact of vaccines. For example, the authors didn’t include data for some vaccines such as COVID and HPV (human papillomavirus). Also, like with all modelling studies, there are some uncertainties, as data was not available for all time periods and countries.

    Nonetheless, the results show the success of global vaccination programs over time. If we want to continue to see lives saved, we need to keep investing in vaccination locally, regionally and globally.

    The Truth About Vaccines

    Yesterday we asked your views on vaccines, and we got an interesting spread of answers. Of those who responded to the poll, most were in favour of vaccines. We got quite a lot of comments this time too; we can’t feature them all, but we’ll include extracts from a few in our article today, as they raised interesting points!

    Vaccines contain dangerous ingredients that will harm us more than the disease would: True or False?

    False, contextually.

    Many people are very understandably wary of things they know full well to be toxic, being injected into them.

    One subscriber who voted for “Vaccines are poison, and/or are some manner of conspiracy ” wrote:

    ❝I think vaccines from 50–60 years ago are true vaccines and were safer than vaccines today. I have not had a vaccine for many, many years, and I never plan to have any kind of vaccine/shot again.❞

    They didn’t say why they personally felt this way, but the notion that “things were simpler back in the day” is a common (and often correct!) observation regards health, especially when it comes to unwanted additives and ultraprocessing of food.

    Things like aluminum or mercury in vaccines are much like sodium and chlorine in table salt. Sodium and chlorine are indeed both toxic to us. But in the form of sodium chloride, it’s a normal part of our diet, provided we don’t overdo it.

    Additionally, the amount of unwanted metals (e.g. aluminum, mercury) in vaccines is orders of magnitude smaller than the amount in dietary sources—even if you’re a baby and your “dietary sources” are breast milk and/or formula milk.

    In the case of formaldehyde (an inactivating agent), it’s also the dose that makes the poison (and the quantity in vaccines is truly miniscule).

    This academic paper alone cites more sources than we could here without making today’s newsletter longer than it already is:

    Vaccine Safety: Myths and Misinformation

    I have a perfectly good immune system, it can handle the disease: True or False?

    True! Contingently.

    In fact, our immune system is so good at defending against disease, that the best thing we can do to protect ourselves is show our immune system a dead or deactivated version of a pathogen, so that when the real pathogen comes along, our immune system knows exactly what it is and what to do about it.

    In other words, a vaccine.

    One subscriber who voted for “Vaccines are important but in some cases the side effects can be worse ” wrote:

    ❝In some ways I’m vacd out. I got COVid a few months ago and had no symptoms except a cough. I have asthma and it didn’t trigger a lot of congestion. No issues. I am fully vaccinated but not sure I’ll get one in fall.❞

    We’re glad this subscriber didn’t get too ill! A testimony to their robust immune system doing what it’s supposed to, after being shown a recent-ish edition of the pathogen, in deactivated form.

    It’s very reasonable to start wondering: “surely I’m vaccinated enough by now”

    And, hopefully, you are! But, as any given pathogen mutates over time, we eventually need to show our immune system what the new version looks like, or else it won’t recognize it.

    See also: Why Experts Think You’ll Need a COVID-19 Booster Shot in the Future

    So why don’t we need booster shots for everything? Often, it’s because a pathogen has stopped mutating at any meaningful rate. Polio is an example of this—no booster is needed for most people in most places.

    Others, like flu, require annual boosters to keep up with the pathogens.

    Herd immunity will keep us safe: True or False?

    True! Ish.

    But it doesn’t mean what a lot of people think it means. For example, in the UK, “herd immunity” was the strategy promoted by Prime Minister of the hour, Boris Johnson. But he misunderstood what it meant:

    • What he thought it meant: everyone gets the disease, then everyone who doesn’t die is now immune
    • What it actually means: if most people are immune to the disease (for example: due to having been vaccinated), it can’t easily get to the people who aren’t immune

    One subscriber who voted for “Vaccines are critical for our health; vax to the max! ” wrote:

    ❝I had a chiropractor a few years ago, who explained to me that if the general public took vaccines, then she would not have to vaccinate her children and take a risk of having side effects❞

    Obviously, we can’t speak for this subscriber’s chiropractor’s children, but this raises a good example: some people can’t safely have a given vaccine, due to underlying medical conditions—or perhaps it is not available to them, for example if they are under a certain age.

    In such cases, herd immunity—other people around having been vaccinated and thus not passing on the disease—is what will keep them safe.

    Here’s a useful guide from the US Dept of Health and Human Services:

    How does community immunity (a.k.a. herd immunity) work?

    And, for those who are more visually inclined, here’s a graphical representation of a mathematical model of how herd immunity works (you can run a simulation)!

    We urge you to overlook the cliché cover art (we don’t know what they were thinking, going for the headless suited torso) because…

    This one could be the best investment you make in your career this year! You may be wondering what the titular 7 principles are. We won’t keep you guessing; they are:

    1. Professional development: personal excellence, productivity, and time management
    2. Leadership development: mindset and essential leadership skills
    3. Personal development: your motivation, character, and confidence as a leader
    4. Career management: plan your career, get promoted and paid well
    5. Social skills & networking: work and connect with the right people
    6. Business- & company-understanding: the big picture
    7. Commitment: make the decision and commit to becoming a great leader

    A lot of leadership books repeat the same old fluff that we’ve all read many times before… padded with a lot of lengthy personal anecdotes and generally editorializing fluff. Not so here!

    While yes, this book does also cover some foundational things first, it’d be remiss not to. It also covers a whole (much deeper) range of related skills, with down-to-earth, brass tacks advice on putting them into practice.

    This is the kind of book you will want to set as a recurring reminder in your phone, to re-read once a year, or whatever schedule seems sensible to you.

    There aren’t many books we’d put in that category!

  • Walden Farms Caesar Dressing vs. Primal Kitchen Caesar Dressing – 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 Walden Farms Caesar Dressing to Primal Kitchen Caesar Dressing, we picked the Primal Kitchen.

    Why?

    As you can see from the front label, the Walden Farms product has 0 net carbs, 0 calories, and 0 fat. In fact, its ingredients list begins:

    Water, white distilled vinegar, erythritol, corn fiber, salt, microcrystalline cellulose, xanthan gum, titanium dioxide (color)

    …before it gets to something interesting (garlic purée), by which point the amount must be miniscule.

    The Primal Kitchen product, meanwhile, has 140 calories per serving and 15g fat (of which, 1.5g is saturated). However! The ingredients list this time begins:

    Avocado oil, water, organic coconut aminos (organic coconut sap, sea salt), organic apple cider vinegar, organic distilled vinegar, mushroom extract, organic gum acacia, organic guar gum

    …before it too gets to garlic, which this time, by the way, is organic roasted garlic.

    In case you’re wondering about the salt content in both, they add up to 190mg for the Walden Farms product, and 240mg for the Primal Kitchen product. We don’t think that the extra 50mg (out of a daily allowance of 2300–5000mg, depending on whom you ask) is worthy of note.

    In short, the Walden Farms product is made of mostly additives of various kinds, whereas the Primal Kitchen product is made of mostly healthful ingredients.

    So, the calories and fat are nothing to fear.

    For this reason, we chose the product with more healthful ingredients—but we acknowledge that if you are specifically trying to keep your calories down, then the Walden Farms product may be a valid choice.
