Saffron For The Brain (& More)

In yesterday’s edition of 10almonds, one of the items in the “health news from around the world” section was:

Clinical trial finds herbal medicine Sailuotong effective for brain health in older people

But, what is it?

❝SaiLuoTong (SLT) is a modern compound Chinese herbal medicine preparation in capsule form containing standardized extracts of Panax ginseng, Ginkgo biloba, and Crocus sativus L❞

Source: A randomized, double-blind, placebo-controlled, parallel-group 12-week pilot phase II trial of SaiLuoTong (SLT) for cognitive function in older adults with mild cognitive impairment

We’ve written previously about ginseng and ginkgo biloba:

So, what’s this about Crocus sativus L.?

That is the plant better known as saffron. And, for all its wide availability (your local supermarket probably has at least a tiny amount in the spice section), there’s a reason we don’t see much of it:

❝Saffron blooms only once a year and should be collected within a very short duration. It is picked during 3–4 weeks in October-November. The method for the cultivation of saffron contributes greatly to its high price. According to some reports, this species is a sterile triploid and so does not produce fertile seeds. Germination can take 1–6 months at 18°C. It takes 3 years for plants to flower from seed.❞

Source: Crocus sativus L.: A comprehensive review

That’s fascinating, but what does it do for us?

Well, in the words of El Midaoui et al. (2022):

❝In the frame of a double-blind-placebo-controlled study, 30 mg per day supplementation with saffron for 16 weeks resulted in improved cognitive function in patients suffering from mild to moderate Alzheimer’s disease.

Moreover, the follow-up of this study in which the authors evaluated the effects of saffron (30 mg/day) for 22 weeks showed that saffron was as effective as donepezil in the treatment of mild-to-moderate Alzheimer’s disease❞

Read the full review: Saffron (Crocus sativus L.): A Source of Nutrients for Health and for the Treatment of Neuropsychiatric and Age-Related Diseases

Not just that, but it also has powerful antioxidant and anti-inflammatory properties beyond the brain (though the brain is where research has been most focused, due to its neuroprotective effects).

See: Antioxidant Properties of Crocus Sativus L. and Its Constituents and Relevance to Neurodegenerative Diseases; Focus on Alzheimer’s and Parkinson’s Disease

(this, too, is a full research review in its own right; we’re getting a lot of “bang for buck” on papers today)

And more?

Yes, and more. Lots more. To bullet-pointify even just the abstract from another research review:

  • Saffron has been suggested to be effective in the treatment of a wide range of disorders including coronary artery diseases, hypertension, stomach disorders, dysmenorrhea and learning and memory impairments.
  • In addition, different studies have indicated that saffron has anti-inflammatory, anti-atherosclerotic, antigenotoxic and cytotoxic activities. (This is all good; the cytotoxic activities are about killing cancer cells)
  • Antitussive effects of stigmas and petals of C. sativus and its components, safranal and crocin have also been demonstrated.
  • The anticonvulsant and anti-Alzheimer properties of saffron extract were shown in human and animal studies.
  • The efficacy of C. sativus in the treatment of mild to moderate depression was also reported in clinical trial.
  • Administration of C. sativus and its constituents increased glutamate and dopamine levels in the brain in a dose-dependent manner.
  • It also interacts with the opioid system to reduce withdrawal syndrome.
  • C. sativus and its components can be considered as promising agents in the treatment of nervous system disorders.

For more details on any of those items, see:

The effects of Crocus sativus (saffron) and its constituents on nervous system: a review

Is it safe?

The effective dose is 30mg/kg and the LD50 is more than 20g/kg, so yes, it’s very safe. Given the price of it, this also means that if you’re the size of this writer (a little over 70kg, or a little over 150lbs) to poison yourself effectively you’d need to consume about 1.4kg of saffron at a time, which would cost well over $6,000.

Where can I get it?

Your local supermarket probably has a tiny amount in the spice section, or you can get better prices buying it in “bulk” online. Here’s an example product on Amazon, for your convenience

  • Tastes from our past can spark memories, trigger pain or boost wellbeing. Here’s how to embrace food nostalgia

    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.

    Have you ever tried to bring back fond memories by eating or drinking something unique to that time and place?

    It could be a Pina Colada that recalls an island holiday? Or a steaming bowl of pho just like the one you had in Vietnam? Perhaps eating a favourite dish reminds you of a lost loved one – like the sticky date pudding Nanna used to make?

    If you have, you have tapped into food-evoked nostalgia.

    As researchers, we are exploring how eating and drinking certain things from your past may be important for your mood and mental health.

    Bittersweet longing

    First named in 1688 by Swiss medical student, Johannes Hoffer, nostalgia is that bittersweet, sentimental longing for the past. It is experienced universally across different cultures and lifespans from childhood into older age.

    But nostalgia does not just involve positive or happy memories – we can also experience nostalgia for sad and unhappy moments in our lives.

    In the short and long term, nostalgia can positively impact our health by improving mood and wellbeing, fostering social connection and increasing quality of life. It can also trigger feelings of loneliness or meaninglessness.

    We can use nostalgia to turn around a negative mood or enhance our sense of self, meaning and positivity.

    Research suggests nostalgia alters activity in the brain regions associated with reward processing – the same areas involved when we seek and receive things we like. This could explain the positive feelings it can bring.

    Nostalgia can also increase feelings of loneliness and sadness, particularly if the memories highlight dissatisfaction, grieving, loss, or wistful feelings for the past. This is likely due to activation of brain areas such as the amygdala, responsible for processing emotions and the prefrontal cortex that helps us integrate feelings and memories and regulate emotion.

    How to get back there

    There are several ways we can trigger or tap into nostalgia.

    Conversations with family and friends who have shared experiences, unique objects like photos, and smells can transport us back to old times or places. So can a favourite song or old TV show, reunions with former classmates, even social media posts and anniversaries.

    What we eat and drink can trigger food-evoked nostalgia. For instance, when we think of something as “comfort food”, there are likely elements of nostalgia at play.

    Foods you found comforting as a child can evoke memories of being cared for and nurtured by loved ones. The form of these foods and the stories we tell about them may have been handed down through generations.

    Food-evoked nostalgia can be very powerful because it engages multiple senses: taste, smell, texture, sight and sound. The sense of smell is closely linked to the limbic system in the brain responsible for emotion and memory making food-related memories particularly vivid and emotionally charged.

    But, food-evoked nostalgia can also give rise to negative memories, such as of being forced to eat a certain vegetable you disliked as a child, or a food eaten during a sad moment like a loved ones funeral. Understanding why these foods evoke negative memories could help us process and overcome some of our adult food aversions. Encountering these foods in a positive light may help us reframe the memory associated with them.

    What people told us about food and nostalgia

    Recently we interviewed eight Australians and asked them about their experiences with food-evoked nostalgia and the influence on their mood. We wanted to find out whether they experienced food-evoked nostalgia and if so, what foods triggered pleasant and unpleasant memories and feelings for them.

    They reported they could use foods that were linked to times in their past to manipulate and influence their mood. Common foods they described as particularly nostalgia triggering were homemade meals, foods from school camp, cultural and ethnic foods, childhood favourites, comfort foods, special treats and snacks they were allowed as children, and holiday or celebration foods. One participant commented:

    I guess part of this nostalgia is maybe […] The healing qualities that food has in mental wellbeing. I think food heals for us.

    Another explained

    I feel really happy, and I guess fortunate to have these kinds of foods that I can turn to, and they have these memories, and I love the feeling of nostalgia and reminiscing and things that remind me of good times.

    Understanding food-evoked nostalgia is valuable because it provides us with an insight into how our sensory experiences and emotions intertwine with our memories and identity. While we know a lot about how food triggers nostalgic memories, there is still much to learn about the specific brain areas involved and the differences in food-evoked nostalgia in different cultures.

    In the future we may be able to use the science behind food-evoked nostalgia to help people experiencing dementia to tap into lost memories or in psychological therapy to help people reframe negative experiences.

    So, if you are ever feeling a little down and want to improve your mood, consider turning to one of your favourite comfort foods that remind you of home, your loved ones or a holiday long ago. Transporting yourself back to those times could help turn things around.

  • Make Your Vegetables Work Better Nutritionally

    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.

    Most people know that boiling vegetables to death is generally not best for them, but raw isn’t always best either, and if we want to not sabotage our food, then there’s more to bear in mind than “just steam them, then”.

    So, what should we keep in mind?

    Water solubility

    Many nutrients are water-soluble, including vitamin C, vitamin B-complex (as in, the collection of B-vitamins), and flavonoids, as well as many other polyphenols.

    This means that if you cook your vegetables (which includes beans, lentils, etc) in water, a lot of the nutrients will go into the water, and be lost if you then drain that.

    There are, thus, options;

    • Steaming, yes
    • Use just enough water to slow-cook or pressure-cook things that are suitable for slow-cooking, or pressure-cooking such as those beans and lentils. That way, when it’s done, there’s no excess water to drain, and all the nutrients are still in situ.
    • Use as much water as you like, but then keep the excess water to make a soup, sauce, or broth.
    • Use a cooking method other than water, where appropriate. For example, roasting peppers is a much better idea than roasting dried pulses.
    • Consume raw, where appropriate.

    Fat solubility

    Many nutrients are fat-soluble, including vitamins A, D, E, and K, as well as a lot of carotenoids (including heavy-hitters lycopene and β-carotene) and many other polyphenols.

    We’re now going to offer almost the opposite advice to that we had about water solubility. This is because unless they are dried, vegetables already contain water, whereas many contain only trace amounts of fat. Consequently, the advice this time is to add fat.

    There are options:

    • Cook with a modest amount of your favorite healthy cooking oil (our general go-to is extra-virgin olive oil, but avocado oil is great especially for higher temperature cooking, and an argument can be made for coconut oil sometimes)
    • Remember that this goes for roasting, too. Brush those vegetables with a touch of olive oil, and not only will they be delicious, they’ll be more nutritious, too.
    • Drizzle some the the above, if you’re serving things raw and it’s appropriate. This goes also for things like salads, so dress them!
    • Enjoy your vegetables alongside healthy fatty foods such as nuts and seeds (or fatty animal products, if you eat those; fatty fish is a fine option here, in moderation, as are eggs, or fermented dairy products).

    For a deeper understanding: Can Saturated Fats Be Healthy?

    Do not, however, deep-fry your foods unless it’s really necessary and then only for an occasional indulgence that you simply accept will be unhealthy. Not only is deep-frying terrible for the health in a host of ways (ranging from an excess of oil in the resultant food, to acrylamide, to creating Advanced Glycation End-products*), but also those fat-soluble nutrients? Guess where they’ll go. And unlike with the excess vegetable-cooking water that you can turn into soup or whatever, we obviously can’t recommend doing that with deep-fryer oil.

    *see also: Are You Eating AGEs?

    Temperature sensitivity

    Many nutrients are sensitive to temperature, including vitamin C (breaks down when exposed to high temperatures) and carotenoids (are released when exposed to higher temperatures). Another special case is ergothioneine, “the longevity vitamin” that’s not a vitamin, found in mushrooms, which is also much more bioavailable when cooked.

    So, if you’re eating something for vitamin C, then raw is best if that’s a reasonable option.

    And if it’s not a reasonable option? Well, then you can either a) just cope with the fact it’s going to have less vitamin C in it, or b) cook it as gently and briefly as reasonably possible.

    On the other hand, if you’re eating something for carotenoids (especially including lycopene and β-carotene), or ergothioneine, then cooked is best.

    Additionally, if your food is high in oxalates (such as spinach), and you don’t want it to be (for example because you have kidney problems, which oxalates can exacerbate, or would like to get more calcium out of the spinach and into your body, which which oxalic acid would inhibit), then cooked is best, as it breaks down the oxalates.

    Same goes for phytates, another “anti-nutrient” found in some whole grains (such as rice and wheat); cooking breaks it down, therefore cooked is best.

    This latter is not, however, applicable in the case of brown rice protein powder, for those who enjoy that—because phytates aren’t found in the part of the rice that’s extracted to make that.

    And as for brown rice itself? Does contain phytates… Which can be reduced by soaking and heating, preferably both, to the point that the nutritional value is better than it would have been had there not been phytic acid present in the first place; in other words: cooked is best.

    You may be wondering: “who is eating rice raw?” and the answer is: people using rice flour.

  • Kumquat vs Persimmon – 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 kumquat to persimmon, we picked the kumquat.

    Why?

    In terms of macros, kumquats have more protein, though like most fruits, it’s unlike anybody’s eating them for the protein content. More importantly, they have a lot more fiber, for less than half the carbs. It bears mentioning though that (again, like most fruits) persimmon isn’t bad for this either, and both fruits are low glycemic index foods.

    When it comes to vitamins, it’s not close: kumquats have more of vitamins A, B1, B2, B3, B5, B6, B9, E, and choline, while persimmon has more vitamin C. It’s worth noting that kumquats are already a very good source of vitamin C though; persimmon just has more.

    In the category of minerals, kumquats again lead with more calcium, copper, magnesium, manganese, and zinc, while persimmon has more iron, phosphorus, and potassium.

    In short, enjoy both, and/or whatever fruit you enjoy the most, but if looking for nutritional density, kumquats are bringing it.

  • Better Than BMI

    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.

    BMI is a very flawed system, and there are several more useful ways of measuring our bodies. Let’s take a look at them!

    What’s wrong with BMI?

    Oof, what isn’t wrong with BMI?

    In short, it was developed as a demographic-based tool to specifically chart the weight-related health of working-age European white men a little under 200 years ago.

    This means that if you are, perchance, not a working-age European white man in 1830 or so, then it’s not so useful. It’d be like first establishing height norms based on NBA basketball players, and then applying it to the general population, and thus coming to the conclusion that someone who is 6’2″ is very short.

    In long, we did a deep-dive into it here, and in particular what things go dangerously wrong when it’s applied to women, non-white people, athletic people, pregnant people, people under 16 or over 65 and more:

    When BMI Doesn’t Quite Measure Up

    What we usually recommend instead

    For heart disease risk and diabetes risk both, waist circumference is a much more universally reliable indicator. And since those two things tend to affect a lot of other health risks, it becomes an excellent starting point for being aware of many aspects of health.

    Pregnancy will still throw off waist circumference a little (measure below the bump, not around it!), but it will nevertheless be more helpful than BMI even then, as it becomes necessary to just increase the numbers a little, according to gestational month and any confounding factors e.g. twins, triplets, etc. Ask your obstetrician about this, as it’s beyond the scope of our article today!

    As to what’s considered a risk:
    • Waist circumference of more than 35 inches for women
    • Waist circumference of more than 40 inches for men

    These numbers are considered applicable across demographics of age, ethnicity, and lifestyle.

    Source: Waist circumference as a vital sign in clinical practice: a Consensus Statement from the IAS and ICCR Working Group on Visceral Obesity

    Bonus extra measurement based on the above

    Important also is waist to hip ratio.

    How to calculate it:

    1. measure your waist circumference
    2. measure your hip circumference
    3. divide the first measurement by the second one

    Because it’s a ratio, it doesn’t matter what units you use (e.g. inches, cm, etc) so long as you use the same units for both measurements.

    The World Health Organization offers the following chart:

    Health riskWomenMen
    Low0.80 or lower0.95 or lower
    Moderate0.81–0.850.96–1.0
    High0.86 or higher1.1 or higher

    Source: Waist Circumference and Waist-Hip Ratio: Report of a WHO Expert Consultation

    This is especially relevant for cardiovascular disease risk:

    Waist circumference and waist-to-hip ratio as predictors of cardiovascular events: meta-regression analysis of prospective studies

    …and also holds true for all-cause mortality:

    Waist-Hip-Ratio as a Predictor of All-Cause Mortality in High-Functioning Older Adults

    An ancient contender that’s still more useful than BMI

    Remember Archimedes? The (perhaps apocryphal) story of his “Eureka” moment in the bathtub when he realized that water displacement could be used to measure the volume of an irregular shape?

    Just like Archimedes (who, the story goes, had been hired to determine the composition of a crown that might or might not have been pure gold), we can use this method to determine body composition, because we have references for how much a given volume of a given substance will weigh, so combing what we know about a body’s weight and volume will tell us about its composition in ways that neither metric could give us alone.

    Indeed, it’s one of the commonly-mentioned flaws of BMI that muscle weighs more than fat, and Archimedes’ method not only avoids that problem, but also, actually turns that knowledge (muscle weighs more than fat) to our advantage.

    It’s called “hydrostatic weighing” now:

    Hydrostatic Weighing: Evaluation of body composition parameters using various diagnostic methods: A meta analysis study

    You may be wondering: what about bones? Or internal organs?

    The fact is that those are slightly confounding factors that do get in the way of a truly accurate analysis, but the variation in how much one person’s skeleton weighs vs another’s, or one person’s set of organs weigh than another’s, is too small to make an important difference to the health implications.

    Lastly…

    Hydrostatic weighing isn’t the only way to work out how much of our body is made of fat; if you have for example a smart scale at home (like this one) that tells you your body fat percentage, that is an estimate based on bioelectrical impedance analysis.

    It’s less accurate than the hydrostatic method, but easier to do at home!

    As to what percentages are “best”, healthy body fat percentages are (assuming normal hormones) generally considered to be in the range of 20–25% for women and 15–20% for men.

  • Holding Back The Clock on Aging

    Holding Back The Clock on Aging

    Dr. Eric Verdin specializes in Holding Back The Clock, with a focus on Aging.

    This is Dr. Eric Verdin, President and CEO of the Buck Institute of Research on Aging. He’s also held faculty positions at the University of Brussels, the NIH, and the Picower Institute for Medical Research. Dr. Verdin is also a professor of medicine at University of California, San Francisco.

    Dr. Verdin’s laboratory focuses on the role of epigenetic regulators (especially the behaviors of certain enzymes) in the aging process. He studies how metabolism, diet, and chemical factors regulate the aging process and its associated diseases, including Alzheimer’s.

    He has published more than 210 scientific papers and holds more than 15 patents. He is a highly cited scientist and has been recognized for his research with a Glenn Award for Research in Biological Mechanisms of Aging.

    And that’s just what we could fit here! Basically, he knows his stuff.

    What we can do

    Dr. Verdin’s position is bold, but rooted in evidence:

    ❝Lifestyle is responsible for about 93% of our longevity—only about 7% is genetics. Based on the data, if implementing health lifestyle choices, most people could live to 95 in good health. So there’s 15 to 17 extra years of healthy life that is up for grabs❞

    ~ Dr. Eric Verdin

    See for example:

    How we can do it

    Well, we all know “the big five”:

    • Good diet (Mediterranean Diet as usual is recommended)
    • Good exercise (more on this in a moment)
    • Good sleep (more on this in a moment)
    • Avoid alcohol (not controversial)
    • Don’t smoke (need we say more)

    When it comes to exercise, generally recognized as good is at least 150 minutes per week of moderate intensity exercise (for example, a brisk walk, or doing the gardening), and at least three small sessions a week of high intensity exercise, unless contraindicated by some medical condition.

    As for Dr. Verdin’s take on this…

    What Dr. Verdin recommends is:

    • make it personalized
    • make it pre-emptive
    • make it better

    The perfect exercise plan is only perfect if you actually do it. And if you actually can do it, for that matter.

    Prevention is so much better (and easier) than cure for a whole array of maladies. So while there may be merit in thinking “what needs fixing”, Dr. Verdin encourages us to take extra care to not neglect factors of our health that seem “good enough”. Because, give them time and neglect, and they won’t be!

    Wherever we’re at in life and health, there’s always at least some little way we could make it a bit better. Dr. Verdin advises us to seek out those little improvements, even if it’s just a nudge better here, a nudge better there, all those nudges add up!

    About sleep…

    It’s perhaps the easiest one to neglect (writer’s note: as a writer, I certainly feel that way!), but his biggest take-away tip for this is:

    Worry less about what time you set an alarm for in the morning. Instead, set an alarm for the evening—to remind you when to go to bed.

    Want to hear directly from the man himself?

    Here he is speaking on progress we can expect for the next decade in the field of aging research, as part of the 100 Minutes of Longevity session at The Longevity Forum, a few months ago:

  • New News From The Centenarian Blue Zones

    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.

    From Blue To Green…

    We sometimes write about supercentenarians, which word is usually used in academia to refer to people who are not merely over 100 years of age, but over 110 years. These people can be found in many countries, but places where they have been found to be most populous (as a percentage of the local population) have earned the moniker “Blue Zones”—of which Okinawa and Sardinia are probably the most famous, but there are others too.

    This is in contrast to, for example “Red Zones”, a term often used for areas where a particular disease is endemic, or areas where a disease is “merely” epidemic, but particularly rife at present.

    In any case, back to the Blue Zones, where people live the longest and healthiest—because the latter part is important too! See also:

    • Lifespan: how long we live
    • Healthspan: how long we stay healthy (portmanteau of “healthy lifespan”)

    Most of our readers don’t live in a Blue Zone (in fact, many live in the US, which is a COVID Red Zone, a diabetes Red Zone, and a heart disease Red Zone), but that doesn’t mean we can’t all take tips from the Blue Zones and apply them, for example:

    You may be wondering… How much good will this do me? And, we do have an answer for that:

    When All’s Said And Done, How Likely Are You To Live To 100?

    Now that we’re all caught-up…

    The news from the Blues

    A team of researchers did a big review of observational studies of centenarians and near-centenarians (aged 95+). Why include the near-centenarians, you ask? Well, most of the studies are also longitudinal, and if we’re doing an observational study of the impact of lifestyle factors on a 100-year-old, it’s helpful to know what they’ve been doing recently. Hence nudging the younger-end cutoff a little lower, so as to not begin each study with fresh-faced 100-year-olds whom we know nothing about.

    Looking at thousands of centenarians (and near-centenarians, but also including some supercentenarians, up the age of 118), the researchers got a lot of very valuable data, far more than we have room to go into here (do check out the paper at the bottom of this article, if you have time; it’s a treasure trove of data), but one of the key summary findings was a short list of four factors they found contributed the most to extreme longevity:

    1. A diverse diet with low salt intake: in particular, a wide variety of plant diversity, including protein-rich legumes, though fish featured prominently also. On average they got 57% and 65% of their energy intake from carbohydrates, 12% to 32% from protein, and 27% to 31% from fat. As for salt, they averaged 1.6g of sodium per day, which is well within the WHO’s recommendation of averaging under 2g of sodium per day. As a matter of interest, centenarians in Okinawa itself averaged 1.1g of sodium per day.
    2. Low medication use: obviously there may be a degree of non-causal association here, i.e. the same people who just happened to be healthier and therefore lived longer, correspondingly took fewer medications—they took fewer medications because they were healthier; they weren’t necessarily healthier because they took fewer medications. That said, overmedication can be a big problem, especially in places with a profit motive like the US, and can increase the risk of harmful drug interactions, and side effects that then need more medications to treat the side effects, as well as direct iatrogenic damage (i.e. this drug treats your condition, but as the cost of harming you in some other way). Naturally, sometimes we really do need meds, but it’s a good reminder to do a meds review with one’s doctor once in a while, and see if everything’s still of benefit.
    3. Getting good sleep: not shocking, and this one’s not exactly news. But what may be shocking is that 68% of centenarians reported consistently getting enough good-quality sleep. To put that into perspective, only 35% of 10almonds readers reported regularly getting sleep in the 7–9 hours range.
    4. Rural living environment: more than 75% of the centenarians and near-centenarians lived in rural areas. This is not usually something touted as a Blue Zones thing on lists of Blue zones things, but this review strongly highlighted it as very relevant.
