Pasteurization’s Effect On Risks & Nutrients

In Wednesday’s newsletter, we asked you for your health-related opinions of raw (cow’s) milk, and got the above-depicted, below-described, set of responses:

  • About 47% said “raw milk is dangerous to consume, whereas pasteurization makes it safer”
  • About 31% said “raw milk is a good source of vital nutrients which pasteurization would destroy”
  • About 14% said “both raw milk and pasteurized milk are equally unhealthy”
  • About 9% said “both raw milk and pasteurized milk are equally healthy”

Quite polarizing! So, what does the science say?

“Raw milk is dangerous to consume, whereas pasteurization makes it safer: True or False?”

True! Coincidentally, the 47% who voted for this are mirrored by the 47% of the general US population in a similar poll, deciding between the options of whether raw milk is less safe to drink (47%), just as safe to drink (15%), safer to drink (9%), or not sure (30%):

Public Fails to Appreciate Risk of Consuming Raw Milk, Survey Finds

As for what those risks are, by the way, unpasteurized dairy products are estimated to cause 840x more illness and 45x more hospitalizations than pasteurized products.

This is because unpasteurized milk can (and often does) contain E. coli, Listeria, Salmonella, Cryptosporidium, and other such unpleasantries, which pasteurization kills.

Source for both of the above claims:

Characteristics of U.S. Consumers Reporting Past Year Intake of Raw (Unpasteurized) Milk: Results from the 2016 Food Safety Survey and 2019 Food Safety and Nutrition Survey

(we know the title sounds vague, but all this information is easily visible in the abstract, specifically, the first two paragraphs)

Raw milk is a good source of vital nutrients which pasteurization would destroy: True or False?

False! Whether it’s a “good” source can be debated depending on other factors (e.g., if we considered milk’s inflammatory qualities against its positive nutritional content), but it’s undeniably a rich source. However, pasteurization doesn’t destroy or damage those nutrients.

Incidentally, in the same survey we linked up top, 16% of the general US public believed that pasteurization destroys nutrients, while 41% were not sure (and 43% knew that it doesn’t).

Note: for our confidence here, we are skipping over studies published by, for example, dairy farming lobbies and so forth. Those do agree, by the way, but nevertheless we like sources to be as unbiased as possible. The FDA, which is not completely unbiased, has produced a good list of references for this, about half of which we would consider biased, and half unbiased; the clue is generally in the journal names. For example, Food Chemistry and the Journal of Food Science and Journal of Nutrition are probably less biased than the International Dairy Association and the Journal of Dairy Science:

FDA | Raw Milk Misconceptions and the Danger of Raw Milk Consumption

this page covers a lot of other myths too, more than we have room to “bust” here, but it’s very interesting reading and we recommend to check it out!

Notably, we also weren’t able to find any refutation by counterexample on PubMed, with the very slight exception that some studies sometimes found that in the case of milks that were of low quality, pasteurization can reduce the vitamin E content while increasing the vitamin A content. For most milks however, no significant change was found, and in all cases we looked at, B-vitamins were comparable and vitamin D, popularly touted as a benefit of cow’s milk, is actually added later in any case. And, importantly, because this is a common argument, no change in lipid profiles appears to be findable either.

In science, when something has been well-studied and there aren’t clear refutations by counterexample, and the weight of evidence is clearly very much tipped into one camp, that usually means that camp has it right.

Milk generally is good/bad for the health: True or False?

True or False, depending on what we want to look at. It’s definitely not good for inflammation, but the whole it seems to be cancer-neutral and only increases heart disease risk very slightly:

  • Keep Inflammation At Bay ← short version is milk is bad, fermented milk products are fine in moderation
  • Is Dairy Scary? ← short version is that milk is neither good nor terrible; fermented dairy products however are health-positive in numerous ways when consumed in moderation

You may be wondering…

…how this goes for the safety of dairy products when it comes to the bird flu currently affecting dairy cows, so:

    How To Always Follow Through

    ❝Two roads diverged in a wood, and I—
    I took the one less traveled by,
    And that has made all the difference:
    Now my socks are wet.❞

    ~ with apologies to Robert Frost

    The thing is, much like a different Robert wrote, “The best-laid schemes o’ mice an’ men gang aft agley”, and when we have a plan and the unexpected occurs, we often find ourselves in a position of “well then, now what?”

    This goes for New Year’s Resolutions that lasted until around January the 4th, and it goes for “xyz in a month” plans of diet, exercise, or so forth.

    We’ve written before on bolstering flagging motivation when all is as expected but we just need an extra boost:

    How To Keep On Keeping On… Long Term!

    …but what about when the unexpected happens?

    First rule: wear a belt and suspenders

    Not literally, unless that’s your thing. But you might have heard this phrase from the business world, and it applies to healthful practices too:

    If your primary plan fails, you need a second one already in place.

    In business, we see this as “business continuity management”. For example, your writer here, I have backups for every important piece of tech I own, Internet connections from two different companies in case one goes down, and if there’s a power cut, I have everything accessible and sync’d on a fully-charged tablet so I can complete my work there if necessary. And yes, I have low-tech coffee-brewing equipment too.

    In health, we should be as serious. We all learned back in 2020 that grocery stores and supply chains can fail; how do we eat healthily when all that is on sale is an assortment of random odds and ends? The answer, as we now know because hindsight really is 2020 in this case, is to keep a well-stocked pantry of healthy things with a long shelf life. Also a good stock of whatever supplements we take, and medicines, and water. And maintain them and rotate the stock!

    And what of exercise? We must not rely on gyms, we can use and enjoy them sure, but we should have at least one good go-to routine for which we need nothing more than a bit of floorspace at home.

    If you’re unsure where to start with that one, we strongly recommend this book that we reviewed recently:

    Science of Pilates: Understand the Anatomy and Physiology to Perfect Your Practice – by Tracy Ward

    Second rule: troubleshoot up front

    With any given intended diet or exercise regime or other endeavor, we must ask ourselves: what could prevent me from doing this? Set a timer for at least 10 minutes, and write down as many things as possible. Then plan for those.

    You can read a bit more about some of this here, the below article was written about facing depression and anxiety, but if you can enact your plans when unmotivated and fearful, then you will surely be able to enact them when not, so this information is good anyway:

    When You Know What You “Should” Do (But Knowing Isn’t The Problem)

    Third rule: don’t err the same way twice

    We all screw up sometimes. To err is, indeed, human. So to errantly eat the wrong food, or do so at the wrong time, or miss a day’s exercise session etc, these things happen.

    Just, don’t let it happen twice.

    Once is an outlier; twice is starting to look like a pattern.

  • Imposter Syndrome (and why almost everyone has it)

    Imposter Syndrome (and why almost everyone has it)

    Imposter syndrome is the pervasive idea that we’re not actually good enough, people think we are better than we are, and at any moment we’re going to get found out and disappoint everyone.

    Beyond the workplace

    Imposter syndrome is most associated with professionals. It can range from a medical professional who feels like they’ve been projecting an image of confidence too much, to a writer or musician who is sure that their next piece will never live up to the acclaim of previous pieces and everyone will suddenly realize they don’t know what they’re doing, to a middle-manager who feels like nobody above or below them realizes how little they know how to do.

    But! Less talked-about (but no less prevalent) is imposter syndrome in other areas of life. New parents tend to feel this strongly, as can the “elders” of a family that everyone looks to for advice and strength and support. Perhaps worst is when the person most responsible for the finances of a household feels like everyone just trusts them to keep everything running smoothly, and maybe they shouldn’t because it could all come crashing down at any moment and everyone will see them for the hopeless shambles of a human being that they really are.

    Feelings are not facts

    And yet (while everyone makes mistakes sometimes) the reality is that we’re all doing our best. Given that imposter syndrome affects up to 82% of people, let’s remember to have some perspective. Everyone feels like they’re winging it sometimes. Everyone feels the pressure.

    Well, perhaps not everyone. There’s that other 18%. Some people are sure they’re the best thing ever. Then again, there’s probably some in that 18% that actually feel worse than the 82%—they just couldn’t admit it, even in an anonymized study.

    But one thing’s for sure: it’s very, very common. Especially in high-performing women, by the way, and people of color. In other words, people who typically “have to do twice as much to get recognized as half as good”.

    That said, the flipside of this is that people who are not in any of those categories may feel “everything is in my favor, so I really have no excuse to not achieve the most”, and can sometimes take very extreme actions to try to avoid perceived failure, and it can be their family that pays the price.

    Things to remember

    If you find imposter syndrome nagging at you, remember these things:

    • There are people far less competent than you, doing the same thing
    • Nobody knows how to do everything themselves, especially at first
    • If you don’t know how to do something, you can usually find out
    • There is always someone to ask for help, or at least advice, or at least support

    At the end of the day, we evolved to eat fruit and enjoy the sun. None of us are fully equipped for all the challenges of the modern world, but if we do our reasonable best, and look after each other (and that means that you too, dear reader, deserve looking after as well), we can all do ok.

  • How To Unchoke Yourself If You Are Dying Alone

    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.

    The first things that most people think of, won’t work. This firefighter advises on how to actually do it:

    Steps to take

    Zero’th step: he doesn’t mention this, but try coughing first. You might think coughing will be a natural reaction anyway, but that tends only to happen automatically with small partial obstructions, not a complete blockage. Either way, try to cough forcefully to see if it dislodges whatever you’re choking on. If that doesn’t work…

    Firstly: don’t rely on calling for help if you’re alone and cannot speak; you’re unlikely to be able to communicate and you will just waste time (when you don’t have time to waste). Even if you call emergency services and they trace your location, chances are that, at most, a cop car will show up some hours later to see what it was about. They will not dispatch an ambulance on the strength of “someone called and said nothing”.

    Secondly, it is probable that will not be able to perform an abdominal thrust (also called Heimlich maneuvre in the US) on yourself the way you could on another person, and hitting your chest with your hand will produce insufficient force even if you’re quite strong. Nor are you likely to be able to slap yourself on the back to way you might another person.

    Instead, he advises:

    • Find a sturdy object: use a chair, table, countertop, or another firm surface that has an edge.
    • Use gravity to perform self-Heimlich: position yourself with the edge of the object just below your sternum (he says ribcage, but the visuals show he clearly means the bottom of the sternum, where the diaphragm is, not the lower ribs). Fall onto the object forcefully to create pressure and dislodge the obstruction. This will not be fun.
    • If it doesn’t work indoors: move to a visible outdoor location like your yard or a neighbor’s lawn. Falling visibly on the ground will likely alert someone to call for help.

    While doing the above, remain as calm as possible, as this will not only increase the length of time you have before passing out, but will also help avoid your throat muscles tightening even more, worsening the choking.

    After doing the above, seek medical attention now that you can communicate; you’ve probably broken some ribs and you might have organ damage.

    It’s Q&A Day at 10almonds!

    Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!

    In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!

    As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!

    So, no question/request too big or small

    ❝Avid coffee drinker so very interested in the results Also question Is there something that you could take or eat that would prevent the caffeine from stimulating the kidneys? I tried to drink decaf from morning to night not a good result! Thanks❞

    That is a good question! The simple answer is “no” (but keep reading, because all is not lost)

    There’s no way (that we yet know of) to proof the kidneys against the stimulating effect of caffeine. This is especially relevant because part of caffeine’s stimulating effect is noradrenergic, and that “ren” in the middle there? It’s about the kidneys. This is just because the adrenal gland is situated next to them (actually, it’s pretty much sitting on top of them), hence the name, but it does mean that the kidneys are about the hardest thing in the body to have not affected by caffeine.

    However! The effects of caffeine in general can be softened a little with l-theanine (found in tea, or it can be taken as a supplement). It doesn’t stop it from working, but it makes the curve of the effect a little gentler, and so it can reduce some unwanted side effects.

    You can read more about l-theanine here:

    L-Theanine: What’s The Tea?

    ❝How to jump start a inactive metabolism and keep it going? THANKYOU❞

    The good news is, if you’re alive, your metabolism is active (it never stops!). So, it may just need perking up a little.

    As for keeping it going, well, that’s what we’re here for! We’re all in favor of healthy longevity.

    We’ll do a main feature soon on what we can do to influence our metabolism in either direction, but to give some quick notes here:

    • A lot of our metabolism is influenced by genes and is unalterable (without modifying our genes, anyway)
    • Metabolism isn’t just one thing—it’s many. And sometimes, parts of our metabolism can be much quicker or slower than others.
    • When people talk about wanting a “faster metabolism”, they’re usually referring to fat-burning, and that’s just a small part of the picture, but we understand that it’s a focal point for many.

    There really is enough material for a whole main feature on metabolic tweaks, though, so watch this space!

    ❝Why the name “10 Almonds?” Is this recommended by the Doctor? A daily dosage? And, if so, why? Thanks! Please answer me…I truly want to know!❞

    Almonds are very nutritionally dense, and for example 20g of almonds (so, about 20 almonds) would give a 100% daily dose of zinc, amongst other nutrients.

    We also do like to think that we give our readers an easily digestible dose of condensed “nutrition” in the form of health information.

    However! That’s not actually the reason at all. It’s a reference to a viral Facebook hoax! There was a post going around that claimed:

    ❝HEADACHE REMEDY. Eat 10–12 almonds, the equivalent of two aspirins, next time you have a headache❞ ← not true!

    It made us think about how much health-related disinformation there was circulating online! So, calling ourselves 10almonds was a bit of a nod to that story, but also a reminder to ourselves:

    We must always publish information with good scientific evidence behind it!

  • Avocado vs Olives – 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 avocado to olives, we picked the avocado.

    Why?

    Both are certainly great! And when it comes to their respective oils, olive oil wins out as it retains many micronutrients that avocado oil loses. But, in their whole form, avocado beats olive:

    In terms of macros, avocado has more protein, carbs, fiber, and (healthy) fats. Simply, it’s more nationally-dense than the already nutritionally-dense food that is olives.

    When it comes to vitamins, olives are great but avocados really shine; avocado has more of vitamins B1, B2, B3, B5, B6, B7 B9, C, E, K, and choline, while olives boast only more vitamin A.

    In the category of minerals, things are closer to even; avocado has more magnesium, manganese, phosphorus, potassium, and zinc, while olives have a lot more calcium, copper, iron, and selenium. Still, a marginal victory for avocado here.

    In short, this is another case of one very healthy food looking bad by standing next to an even better one, so by all means enjoy both—if you’re going to pick one though, avocado is the more nutritionally dense.

  • Body by Science – by Dr. Doug McGuff & John Little

    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.

    The idea that you’ll get a re-sculpted body at 12 minutes per week is a bold claim, isn’t it? Medical Doctor Doug McGuff and bodybuilder John Little team up to lay out their case. So, how does it stand up to scrutiny?

    First, is it “backed by rigorous research” as claimed? Yes… with caveats.

    The book uses a large body of scientific literature as its foundation, and that weight of evidence does support this general approach:

    • Endurance cardio isn’t very good at burning fat
    • Muscle, even just having it without using it much, burns fat to maintain it
    • To that end, muscle can be viewed as a fat-burning asset
    • Muscle can be grown quickly with short bursts of intense exercise once per week

    Why once per week? The most relevant muscle fibers take about that long to recover, so doing it more often will undercut gains.

    So, what are the caveats?

    The authors argue for slow reps of maximally heavy resistance work sufficient to cause failure in about 90 seconds. However, most of the studies cited for the benefits of “brief intense exercise” are for High Intensity Interval Training (HIIT). HIIT involves “sprints” of exercise. It doesn’t have to be literally running, but for example maxing out on an exercise bike for 30 seconds, slowing for 60, maxing out for 30, etc. Or in the case of resistance work, explosive (fast!) concentric movements and slow eccentric movements, to work fast- and slow-twitch muscle fibers, respectively.

    What does this mean for the usefulness of the book?

    • Will it sculpt your body as described in the blurb? Yes, this will indeed grow your muscles with a minimal expenditure of time
    • Will it improve your body’s fat-burning metabolism? Yes, this will indeed turn your body into a fat-burning machine
    • Will it improve your “complete fitness”? No, if you want to be an all-rounder athlete, you will still need HIIT, as otherwise anything taxing your under-worked fast-twitch muscle fibers will exhaust you quickly.

    Bottom line: read this book if you want to build muscle efficiently, and make your body more efficient at burning fat. Best supplemented with at least some cardio, though!
