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, and the good news is, the heat of pasteurization kills it:

With all this bird flu around, how safe are eggs, chicken or milk?

  • Sticky Jackfruit Burgers

    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.

    All the taste and experience of pulled pork, without the increased risk of cancer and metabolic disease. On the contrary, jackfruit introduces lots of fiber, vitamins, carotenoids, and flavanones. We’ll have to do a main feature about jackfruit sometime; it’s an unusual fruit especially for its protein content, but for now, let’s get cooking!

    You will need

    • 1 can (14oz/400g) green jackfruit, drained (the flesh will not, in fact, be green—this is referring to the fruit being unripe and thus still firm in texture, which is what we want. The outside of the fruit, which will not be in the can, will have been green)
    • 1/4 red cabbage, thinly sliced
    • 1/2 carrot, grated
    • 6 mangetout, thinly sliced
    • 2 tbsp mayonnaise (your preference what kind, and yes, vegan is fine too)
    • 1 tbsp extra virgin olive oil
    • 1 tbsp gochujang paste (if you can’t find gochujang paste locally, you can either order it online (here it is on Amazon) or substitute with harissa paste, which is not the same—it uses different spices—but will do the same job here re texture, umami taste, and level of spiciness)
    • 1 tbsp soy sauce
    • 1 tbsp balsamic vinegar
    • 1 tsp apple cider vinegar
    • 1 tsp garlic paste
    • 1 tsp tomato paste
    • 1 tsp ginger paste
    • 1 tsp chili flakes
    • 3½ fl oz water
    • 2 burger buns (unless you make them yourself, burger buns will probably not be healthy; you can, however, also look for small round wholemeal breads—the name of which varies far too much by region for us to try to get a catch-all name here—and use them in place of burger buns)

    Method

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

    1) Combine the garlic paste, ginger paste, tomato paste, gochujang paste, soy sauce, balsamic vinegar, and chili flakes in a saucepan

    2) Boil the 3½ fl oz water we mentioned; add it to the saucepan, mixing well, turn on the heat and let it simmer for 5 minutes or until it is thick and sticky (it will thicken more as it cools, too, so don’t worry if it doesn’t seem thick enough yet). Set it aside.

    3) Dry the jackfruit (using strong kitchen paper should be fine), add the olive oil to a skillet and bring it to a high heat; add the jackfruit and fry on both sides for a few minutes, until it looks cooked (remember, while this may look like animal meat, it’s not, so there’s no danger of undercooking here).

    4) When the jackfruit looks a nice golden-brown, add two thirds of the sauce from the saucepan, and break apart the jackfruit a bit (this can be done with a wooden/bamboo spatula, so as to not damage your pan), When it all looks how you’d expect pulled jackfruit (or pulled pork) to look, take it off the heat.

    5) Combine the carrot, cabbage, and mangetout in a small bowl, adding the apple cider vinegar and mixing well; this will be the coleslaw element

    6) Mix the remaining sauce with the mayonnaise

    7) (optional) toast the burger buns

    8) Assemble the burgers; we recommend the following order: bottom bun, pulled jackfruit, coleslaw, gochujang mayo, top bun

    Enjoy!

    There are a lot of books about addiction, so what sets this one apart?

    Mostly, it’s that this one maintains that addiction is neither good nor bad per se—just, some behaviors and circumstances are. Behaviors and circumstances caused, directly or indirectly, by addiction.

    But, Dr. Linden argues, not every addiction has to be so. Especially behavioral addictions; the rush of dopamine one gets from a good session at the gym or learning a new language, that’s not a bad thing, even if they can fundamentally be addictions too.

    Similarly, we wouldn’t be here as a species without some things that rely on some of the same biochemistry as addictions; orgasms and eating food, for example. Yet, those very same urges can also inconvenience us, and in the case of foods and other substances, can harm our health.

    In this book, the case is made for shifting our addictive tendencies to healthier addictions, and enough information is given to help us do so.

    Bottom line: if you’d like to understand what is going on when you get waylaid by some temptation, and how to be tempted to better things, this book can give the understanding to do just that.

    Gene Expression & Gut Health

    Dr. Tim Spector, a renowned expert in Gut Health 2.0, offers valuable insights and expertise on the latest advancements in improving gut health and overall well-being. With years of research and

    This is Dr. Tim Spector. After training in medicine and becoming a consultant rheumatologist, he’s turned his attention to medical research, and is these days a specialist in twin studies, genetics, epigenetics, microbiome, and diet.

    What does he want us to know?

    For one thing: epigenetics are for more than just getting your grandparents’ trauma.

    More usefully: there are things we can do to improve epigenetic factors in our body

    DNA is often seen as the script by which our body does whatever it’s going to do, but it’s only part of the story. Thinking of DNA as some kind of “magical immutable law of reality” overlooks (to labor the metaphor) script revisions, notes made in the margins, directorial choices, and ad-lib improvizations, as well as the quality of the audience’s hearing and comprehension.

    Hence the premise of one of Dr. Spector’s older books, “Identically Different: Why We Can Change Our Genes

    (*in fact, it was his first, from all the way back in 2013, when he’d only been a doctor for 34 years)

    Gene expression will trump genes every time, and gene expression is something that can often be changed without getting in there with CRISPR / a big pair of scissors and some craft glue.

    How this happens on the micro level is beyond the scope of today’s article; part of it has to do with enzymes that get involved in the DNA transcription process, and those enzymes in turn are despatched or not depending on hormonal messaging—in the broadest sense of “hormonal”; all the body’s hormonal chemical messengers, not just the ones people think of as hormones.

    However, hormonal messaging (of many kinds) is strongly influenced by something we can control relatively easily with a little good (science-based) knowledge: the gut.

    The gut, the SAD, and the easy

    In broad strokes: we know what is good for the gut. We’ve written about it before at 10almonds:

    Making Friends With Your Gut (You Can Thank Us Later)

    This is very much in contrast with what in scientific literature is often abbreviated “SAD”, the Standard American Diet, which is very bad for the gut.

    However, Dr. Spector (while fully encouraging everyone to enjoy an evidence-based gut-healthy diet) wanted to do one better than just a sweeping one-size-fits-all advice, so he set up a big study with 15,000 identical twins; you can read about it here: TwinsUK

    The information that came out of that was about a lot more than just gene expression and gut health, but it did provide the foundation for Dr. Spector’s next project, ZOE.

    ZOE crowdsources huge amounts of data including individual metabolic responses to standardized meals in order to predict personalized food responses based on individual biology and unique microbiome profile.

    In other words, it takes the guesswork out of a) knowing what your genes mean for your food responses b) tailoring your food choices with your genetic expression in mind, and c) ultimately creating a positive feedback loop to much better health on all levels.

    Now, this is not an ad for ZOE, but if you so wish, you can…

  • Which gut drugs might end up in a lawsuit? Are there really links with cancer and kidney disease? Should I stop taking them?

    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.

    Common medicines used to treat conditions including heartburn, reflux, indigestion and stomach ulcers may be the subject of a class action lawsuit in Australia.

    Lawyers are exploring whether long-term use of these over-the-counter and prescription drugs are linked to stomach cancer or kidney disease.

    The potential class action follows the settlement of a related multi-million dollar lawsuit in the United States. Last year, international pharmaceutical company AstraZeneca settled for US$425 million (A$637 million) after patients made the case that two of its drugs caused significant and potentially life-threatening side effects.

    Specifically, patients claimed the company’s drugs Nexium (esomeprazole) and Prilosec (omeprazole) increased the risk of kidney damage.

    Which drugs are involved in Australia?

    The class of drugs we’re talking about are “proton pump inhibitors” (sometimes called PPIs). In the case of the Australian potential class action, lawyers are investigating:

    • Nexium (esomeprazole)
    • Losec, Asimax (omeprazole)
    • Somac (pantoprazole)
    • Pariet (rabeprazole)
    • Zoton (lansoprazole).

    Depending on their strength and quantity, these medicines are available over-the-counter in pharmacies or by prescription.

    They have been available in Australia for more than 20 years and are in the top ten medicines dispensed through the Pharmaceutical Benefits Scheme.

    They are used to treat conditions exacerbated by stomach acid. These include heartburn, gastric reflux and indigestion. They work by blocking the protein responsible for pumping acid into the stomach.

    These drugs are also prescribed with antibiotics to treat the bacterium Helicobacter pylori, which causes stomach ulcers and stomach cancer.

    This class of drugs is also used with antibiotics to treat Helicobacter pylori infections. nobeastsofierce/Shutterstock

    What do we know about the risks?

    Appropriate use of proton pump inhibitors plays an important role in treating several serious digestive problems. Like all medicines, there are risks associated with their use depending on how much and how long they are used.

    When proton pump inhibitors are used appropriately for the short-term treatment of stomach problems, they are generally well tolerated, safe and effective.

    Their risks are mostly associated with long-term use (using them for more than a year) due to the negative effects from having reduced levels of stomach acid. In elderly people, these include an increased risk of gut and respiratory tract infections, nutrient deficiencies and fractures. Long-term use of these drugs in elderly people has also been associated with an increased risk of dementia.

    In children, there is an increased risk of serious infection associated with using these drugs, regardless of how long they are used.

    How about the cancer and kidney risk?

    Currently, the Australian consumer medicine information sheets that come with the medicines, like this one for esomeprazole, do not list stomach cancer or kidney injury as a risk associated with using proton pump inhibitors.

    So what does the evidence say about the risk?

    Over the past few years, there have been large studies based on observing people in the general population who have used proton pump inhibitors. These studies have found people who take them are almost two times more likely to develop stomach cancer and 1.7 times more likely to develop chronic kidney disease when compared with people who are not taking them.

    In particular, these studies report that users of the drugs lansoprazole and pantoprazole have about a three to four times higher risk than non-users of developing chronic kidney disease.

    While these observational studies show a link between using the drugs and these outcomes, we cannot say from this evidence that one causes the other.

    Human kidney illustration with blood vessels
    Researchers have not yet shown these drugs cause kidney disease. crystal light/Shutterstock

    What can I do if I’m worried?

    Several digestive conditions, especially reflux and heartburn, may benefit from simple dietary and lifestyle changes. But the overall evidence for these is not strong and how well they work varies between individuals.

    But it may help to avoid large meals within two to three hours before bed, and reduce your intake of fatty food, alcohol and coffee. Eating slowly and getting your weight down if you are overweight may also help your symptoms.

    There are also medications other than proton pump inhibitors that can be used for heartburn, reflux and stomach ulcers.

    These include over-the-counter antacids (such as Gaviscon and Mylanta), which work by neutralising the acidic environment of the stomach.

    Alternatives for prescription drugs include nizatidine and famotidine. These work by blocking histamine receptors in the stomach, which decreases stomach acid production.

    If you are concerned about your use of proton pump inhibitors it is important to speak with your doctor or pharmacist before you stop using them. That’s because when you have been using them for a while, stopping them may result in increased or “rebound” acid production.

  • Superfood-Stuffed Squash

    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.

    This stuffed squash recipe is packed with so many nutrient-dense ingredients, yet it feels delightfully decadent—a great recipe to have up your sleeve ready for fall.

    You will need

    • 1 large or two medium butternut squashes, halved lengthways and seeds removed (keep them; they are full of nutrients! You can sprout them, or dry them to use them at your leisure), along with some of the flesh from the central part above where the seeds are, so that there is room for stuffing
    • 2 cups low-sodium vegetable stock
    • 1 cup wild rice, rinsed
    • 1 medium onion, finely chopped
    • ½ cup walnuts, roughly chopped
    • ½ cup dried cranberries goji berries ← why goji berries? They have even more healthful properties than cranberries, and cranberries are hard to buy without so much added sugar that the ingredients list looks like “cranberries (51%), sugar (39%), vegetable oil (10%)”, whereas when buying goji berries, the ingredients list says “goji berries”, and they do the same culinary job.
    • ¼ cup pine nuts
    • ½ bulb garlic, minced
    • 1 tbsp dried thyme or 2 tsp fresh thyme, destalked
    • 1 tbsp dried rosemary or 2 tsp fresh rosemary, destalked
    • 1 generous handful fresh parsley, chopped
    • 1 tbsp chia seeds
    • 1 tbsp nutritional yeast
    • 1 tbsp black pepper, coarse ground
    • ½ tsp MSG or 1 tsp low-sodium salt
    • Extra virgin olive oil, for brushing and frying
    • Aged balsamic vinegar, to serve (failing this, make a balsamic vinegar reduction and use that; it should have a thicker texture but still taste acidic and not too sweet; the thickness should come from the higher concentration of grape must and its natural sugars; no need to add sugar)

    Method

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

    1) Preheat the oven to 400°F / 200°C.

    2) Brush the cut sides of the squash with olive oil; sprinkle with a pinch of MSG/salt and a little black pepper (grind it directly over the squash if you are using a grinder; hold the grinder high though so that it distributes evenly—waiters in restaurants aren’t just being dramatic when they do that with pepper or Parmesan or such)

    3) Arrange them cut-sides-down on a baking tray lined with baking paper, and roast for at least 30 minutes or until tender.

    4) While that is roasting, add the chia seeds to the wild rice, and cook them in the low-sodium vegetable stock, using a rice cooker if available. It should take about the same length of time, but if the rice is done first, set it aside, and if the squash is done first, turn the oven down low to keep it warm.

    5) Heat some oil in a sauté pan (not a skillet without high sides; we’re going to need space in a bit), and fry the chopped onion until translucent and soft. We could say “about 5 minutes” but honestly it depends on your pan as well as the heat and other factors.

    6) Add the seasonings (herbs, garlic, black pepper, MSG/salt, nooch), and cook for a further 2 minutes, stirring thoroughly to distribute evenly.

    7) Add the rice, berries, and nuts, cooking for a further 2 minutes, stirring constantly, ensuring everything is heated evenly.

    8) Remove the squash halves from the oven, turn them over, and spoon the mixture we just made into them, filling generously.

    9) Drizzle a lashing of the aged balsamic vinegar (or balsamic vinegar reduction), to serve.

    Enjoy!
