A Deeper Dive Into Seaweed

We wrote briefly about nori yesterday, when we compared it with well-known superfood spirulina. In nutritional terms, it blew spirulina out of the water:

Spirulina vs Nori – Which Is Healthier?

We also previously touched on it here:

What is nori?

Nori is a seaweed, but that can mean lots of different things. In nori’s case, it’s an aggregate of several kinds of red algae that clump together in the sea.

When dried and/or toasted (which processes improve* the nutritional value rather than diminishing it, by the way), it looks dark green or dark purple to black in color.

*Effects of pan- and air fryer-roasting on volatile and umami compounds and antioxidant activity of dried laver (Porphyra dentata) ← this is nori, by another name

If you enjoy sushi, nori is the dark flat sheety stuff that other things are often wrapped in.

The plant that has animal nutrients

As established in the head-to-head we linked above, nori is a nutritional powerhouse. But not only is it very full of the perhaps-expected vitamins and minerals, it also contains:

Omega-3 fatty acids, including EPA, which plants do not normally have (plants usually have just ALA, which the body can convert into other forms including EPA). While ALA is versatile, having EPA in food saves the body the job of converting it, and thus makes it more readily bioavailable. For more on the benefits of this, see:

What Omega-3 Fatty Acids Really Do For Us

Iodine, which land plants don’t generally have, but seaweed usually does. However, nori contains less iodine than other kinds of seaweed, which is (counterintuitively) good, since other kinds of seaweed often contain megadoses that go too far the other way and can cause different health problems.

  • Recommended daily amount of iodine: 150µg ← note that’s micrograms, not milligrams
  • One 10g serving of dried nori contains: 232µg ← this is good
  • Tolerable daily upper limit of iodine: 1,100µg (i.e: 1.1mg)
  • One 10g serving of dried kombu (kelp) contains: 13,270µg (i.e: 13.3mg) ← this is far too much; not good!

So: a portion of nori puts us into the healthiest spot of the range, whereas a portion of another example seaweed would put us nearly 13x over the tolerable upper limit.

For why this matters, see:

As you might note from the mentions of both hypo- and hyperthyroidism, (which are exacerbated by too little and too much iodine, respectively) hitting the iodine sweet spot is important, and nori is a great way to do that.

Vitamin B12, again not usually found in plants (most vegans supplement, often with nutritional yeast, which is technically neither an animal nor a plant). However, nori scores even higher:

Beyond nutrients

Nori is also one of the few foods that actually live up the principle of a “detox diet”, as it can help remove toxins such as dioxins:

It’s also been…

❝revealed to have anti-aging, anti-cancer, anti-coagulant, anti-inflammatory, anti-microbial, anti-oxidant, anti-diabetic, anti-Alzheimer and anti-tuberculose activities.❞

~ Dr. Şükran Çakir Arica et al.

Read: A study on the rich compounds and potential benefits of algae: A review

(for this to make sense you will need to remember that nori is, as we mentioned, an aggregate of diverse red algae species; in that paper, you can scroll down to Table 1, and see which species has which qualities. Anything whose name starts with “Porphyra” or “Porphridum” is found in nori)

Is it safe?

Usually! There are two potential safety issues:

  1. Seaweed can, while it’s busy absorbing valuable minerals from the sea, also absorb heavy metals if there are such pollutants in the region. For this reason, it is good to buy a product with trusted certifications, such that it will have been tested for such along the way.
  2. Seaweed can, while it’s busy absorbing things plants don’t usually have from the sea, also absorb allergens from almost-equally-small crustaceans. So if you have a seafood allergy, seaweed could potentially trigger that.

  • Human Connection In An All-Too-Busy World

    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.

    Many of us, in many ways, have more discretionary time than ever… On paper.

    But rather than the 8-hour block of work of yesteryear, nowadays the things that take our time often come in a series of short bursts that punctuate our day.

    This means that while in theory, we have n hours of “free” time per day, we actually have 9 minutes here, 23 minutes there, 1 hour 6 minutes somewhere else, and so on.

    Social commitments, meanwhile, tend to require not only that we have time in a block, but also, that the time around that block also be sufficiently free, for travelling, preparation, etc.

    The result? “We must do this again, and not leave it so long next time!” we say, sincerely, to the friend whom we will next see again in approximately 17 months’ time.

    The problem is how our many theoretically-small obligations reduce the rest of our time to “time confetti”, and that happens on the large scale like we saw above, as well as on the small scale of “Ah, I have an hour to relax between these two things” and then suddenly the time is gone, once again reduced to time confetti:

    Time Confetti and the Broken Promise of Leisure

    So, how to maintain human connection with people beyond those with whom we live?

    Some is infinitely better than none

    Let’s say you want to call a friend or relative. There may be generational differences in how much one is expected to arrange this by text first, vs just calling, but either way, you don’t have to have an open-ended block of time, and sometimes, it’s better if you don’t.

    Establish, at the start of the call, “Before we get into catching up, how are we for time, by the way? For my part, I’ll have to go by such-and-such a time”, and then work with that.

    The benefit of doing this is that you’ll both know enough about the time constraints to use the time appropriately; you won’t run out the clock on smalltalk before getting to something big, and you’ll both come away feeling satisfied that you shared and were shared-with in a meaningful fashion.

    In contrast, guessing at time constraints can leave big things clipped off, or else result in someone “looking for a way to politely end this conversation that stopped being interesting a while ago but it’ll seem rude if I say I have to go now”, of the kind that results in someone not being so open to a call next time.

    Don’t rush to dismiss texts as a medium for meaningful connection

    When text messages were first a thing, you’ll remember how we were all working within a very short character limit and a cost-per-message. It was telegrams for the modern age, basically.

    Nowadays, that isn’t so; we can write as much or as little as we like, and this has two benefits:

    1. We can have longer, meaningful conversations around the other stuff in our life. We can reply in seconds, or after making a cup of tea and thinking about it, or after our grocery-chopping trip, or whenever suits us. Suddenly, time confetti isn’t such a barrier to human connection. Writer’s example: my prime social time in this manner is when I’m cooking dinner (which is often about an hour). There’s no way I could have a phonecall while doing that; my bad hearing notwithstanding, I just have my hands full too often with much else going on. But texting? I can do that in the several-minute gaps between assorted culinary tasks, while I’m waiting for the kettle to boil or the onions to brown or whatever.
    2. Sometimes, the brevity makes it easier. A quick text saying “Hey, just to let you know I’m thinking of you, and hope your day is going well!”, or “Unrelated to anything: I was just thinking about how I’m glad to have you in my life; you’re a good friend, and I appreciate that more than I often remember to say. Anyway, that’s all; it was just on my mind. I hope your day is going well!”

    (The cheery closing words in those last two text message examples help signify: “don’t worry, I’m fine and am not looking for anything from you”, which will help the recipient to relax, and counterintuitively, more likely to reply with some kind words of their own, knowing that they’re not signing up for a potentially deep talk when they also have time confetti issues going on)

    Seize the moment (and also let it go)

    You probably have many small interactions with strangers, most days. In the store, walking the dog, at the doctor’s office, etc. So, two things:

    1. Make smalltalk. And if you’re not one for traditional smalltalk topics (weather etc), or even if you are, a level-up is:
    2. Compliment sincerely. Straight out of “How To Win Friends And Influence People”, of course, but it creates a moment of genuine connection; you say a thing, their day is improved, they smile, you complete your business with a smile of your own and go about your day.

    (of course, do steer clear of anything that could be interpreted as flirting, if that is not your intent, and really it should never be your intent when it comes to the captive audience of someone who will get fired if they’re not nice to you)

    But, with a little practice, these little moments add up to a lot more human connection than if we treat the strangers with whom we interact as though they were merely part of the scenery.

  • How Your Exercise Today Gives A Brain Boost Tomorrow

    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.

    Regular 10almonds readers may remember we not long back wrote about a study that showed how daily activity levels, in aggregate, make a difference to brain health over the course of 1–2 weeks (in fact, it was a 9-day study):

    Daily Activity Levels & The Measurable Difference They Make To Brain Health

    Today, we’re going to talk about a new (published today, at time of writing) study that shows the associations between daily exercise levels (amongst other things) and how well people performed in cognitive tests the next day.

    By this we mean: they recorded exercise vs sedentary behavior vs sleep on a daily basis (using wearable tech to track it), and tested them daily with cognitive tests, and looked at how the previous day’s activities (or lack thereof) impacted the next day’s test results.

    Notably, the sample was of older adults (aged 50–83). The sample size wasn’t huge but was statistically significant (n=76) and the researchers are of course calling for more studies to be done with more people.

    What they found

    To put their findings into few words:

    • Consistent light exercise boosts general cognitive performance not just for hours (which was already known) but through the next day.
    • More moderate or vigorous activity than usual in particular led to better working memory and episodic memory the next day.
    • More sleep (especially slow-wave deep sleep) improved episodic memory and psychomotor speed.
    • Sedentary behavior was associated with poorer working memory.

    Let’s define some terms:

    • general cognitive performance = average of scores across the different tests
    • working memory = very short term memory, such as remembering what you came into this room for, or (as an example of a test format) being able to take down a multi-digit number in one go without it being broken down (and then, testing with longer lengths of number until failure)
    • episodic memory = memory of events in a narrative context, where and when they happened, etc
    • psychomotor speed = the speed of connection between perception and reaction in quick-response tests

    These are, of course, all useful things to have, which means the general advice here is to:

    • move more, generally
    • exercise more, specifically
    • sit less, whenever reasonably possible
    • sleep well

  • 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.

    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.

  • Tofu vs Seitan – 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 tofu to seitan, we picked the tofu.

    Why?

    This one is not close!

    In terms of macros, seitan does have about 2x the protein, but it also has 6x the carbs and 6x the sodium of tofu, as well as less fiber than tofu.. So we’ll call it a tie on macros. But…

    Seitan is also much more processed than tofu, as tofu has usually just been fermented and possibly pressed (depending on kind). Seitan, in contrast, is processed gluten that has been extracted from wheat and usually had lots of things happen to it on the way (depending on kind).

    About that protein… Tofu is a complete protein, meaning it has all of the essential amino acids. Seitain, meanwhile, is lacking in lysine.

    When it comes to vitamins and minerals, again tofu easily comes out on top; tofu has 5x the calcium, similar iron, more magnesium, 2x the phosphorous, 150% of the potassium, and contains several other nutrients that seitan doesn’t, such as folate and choline.

    So, easy winning for tofu across the board on micronutrients.

    Tofu is also rich in isoflavones, antioxidant phytonutrients, while seitan has no such benefits.

    So, another win for tofu.

    There are two reasons you might choose seitan:

    • prioritizing bulk protein above all other health considerations
    • you are allergic to soy and not allergic to gluten

    If neither of those things are the case, then tofu is the healthier choice!

  • Meditations for Mortals – by Oliver Burkeman

    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 previously reviewed this author’s “Four Thousand Weeks”, but for those who might have used a lot of those four thousand weeks already, and would like to consider things within a smaller timeframe for now, this work is a 28-day daily reader.

    Now, daily readers are usually 366 days, but the chapters here are not the single page chapters that 366-page daily readers usually have. So, expect to invest a little more time per day (say, about 6 pages for each daily chapter).

    Burkeman does not start the way we might expect, by telling us to take the time to smell the roses. Instead, he starts by examining the mistakes that most of us make most of the time, often due to unexamined assumptions about the world and how it works. Simply put, we’ve often received bad lessons in life (usually not explicitly, but rather, from our environments), and it takes some unpacking first to deal with that.

    Nor is the book systems-based, as many books that get filed under “time management” may be, but rather, is simply principles-based. This is a strength, because principles are a lot easier to keep to than systems.

    The writing style is direct and conversational, and neither overly familiar nor overly academic. It strikes a very comfortably readable balance.

    Bottom line: if you’d like to get the most out of your days, this book can definitely help improve things a lot.
