The Real Immune-Boosters
What comes to your mind when we say “immune support”? Vitamin C and maybe zinc? Those have their place, but there are things we can do that are a lot more important!
It’s just, these things are not talked about as much, because stores can’t sell them to you
Sleep
One of the biggest difference-makers. Get good sleep! Getting at least 7 hours decent sleep (not lying in bed, not counting interruptions to sleep as part of the sleep duration) can improve your immune system by three or four times.
Put another way, people are 3–4 times more likely to get sick if they get less sleep than that on average.

Eat an anti-inflammatory diet
In short, for most of us this means lots of whole plant foods (lots of fiber), and limited sugar, flour, alcohol.
For more details, you can see our main feature on this: Keep Inflammation At Bay!
You may wonder why eating to reduce inflammation (inflammation is a form of immune response) will help improve immune response. Put it this way:
If your town’s fire service is called out eleventy-two times per day to deal with things that are not, in fact, fires, then when there is a fire, they will be already exhausted, and will not do their job so well.
Look after your gut microbiota
Additionally, healthy gut microbiota (fostered by the same diet we just described) help keep your body pathogen-free, by avoiding “leaky gut syndrome” that occurs when, for example, C. albicans (you do not want this in your gut, and it thrives on the things we just told you to avoid) puts its roots through your intestinal walls, making holes in them. And through those holes? You definitely do not want bacteria from your intestines going into the rest of your body.

Actually get that moderate exercise
There’s definitely a sweet-spot here, because too much exercise will also exhaust you and deplete your body’s resources. However, the famous “150 minutes per week” (so, a little over 20 minutes per day, or 25 minutes per day with one day off) will make a big difference.
See: Exercise and the Regulation of Immune Functions
Manage your stress levels (good and bad!)
This one swings both ways:
- Acute stress (like a cold shower) is good for immune response. Think of it like a fire drill for your body.
- Chronic stress (“the general everything” persistently stressful in life) is bad for immune response. This is the fire drill that never ends. Your body’s going to know what to do really well, but it’s going to be exhausted already by the time an actual threat hits.

Supplement, yes.
These are far less critical than the above things, but are also helpful. Good things to take include:

When Age Is A Flexible Number

Aging, Counterclockwise!
In the late 1970s, Dr. Ellen Langer hypothesized that physical markers of aging could be affected by psychosomatic means.
Note: psychosomatic does not mean “it’s all in your head”.
Psychosomatic means “your body does what your brain tells it to do, for better or for worse”
She set about testing that, in what has been referred to since as…
The Counterclockwise Study
A small (n=16) sample of men in their late 70s and early 80s were recruited in what they were told was a study about reminiscing.
Back in the 1970s, it was still standard practice in the field of psychology to outright lie to participants (who in those days were called “subjects”), so this slight obfuscation was a much smaller ethical aberration than in some famous studies of the same era and earlier (cough cough Zimbardo cough Milgram cough).
Anyway, the participants were treated to a week in a 1950s-themed retreat, specifically 1959, a date twenty years prior to the experiment’s date in 1979. The environment was decorated and furnished authentically to the date, down to the food and the available magazines and TV/radio shows; period-typical clothing was also provided, and so forth.
- The control group were told to spend the time reminiscing about 1959
- The experimental group were told to pretend (and maintain the pretense, for the duration) that it really was 1959
The results? On many measures of aging, the experimental group participants became quantifiably younger:
❝The experimental group showed greater improvement in joint flexibility, finger length (their arthritis diminished and they were able to straighten their fingers more), and manual dexterity.
On intelligence tests, 63 percent of the experimental group improved their scores, compared with only 44 percent of the control group. There were also improvements in height, weight, gait, and posture.
Finally, we asked people unaware of the study’s purpose to compare photos taken of the participants at the end of the week with those submitted at the beginning of the study. These objective observers judged that all of the experimental participants looked noticeably younger at the end of the study.❞
Remember, this was after one week.
Her famous study was completed in 1979, and/but not published until eleven years later in 1990, with the innocuous title:
Higher stages of human development: Perspectives on adult growth
You can read about it much more accessibly, and in much more detail, in her book:
Counterclockwise: A Proven Way to Think Yourself Younger and Healthier – by Dr. Ellen Langer
We haven’t reviewed that particular book yet, so here’s Linda Graham’s review, that noted:
❝Langer cites other research that has made similar findings.
In one study, for instance, 650 people were surveyed about their attitudes on aging. Twenty years later, those with a positive attitude with regard to aging had lived seven years longer on average than those with a negative attitude to aging.
(By comparison, researchers estimate that we extend our lives by four years if we lower our blood pressure and reduce our cholesterol.)
In another study, participants read a list of negative words about aging; within 15 minutes, they were walking more slowly than they had before.❞
Read the review in full:
Aging in Reverse: A Review of Counterclockwise
The Counterclockwise study has been repeated since, and/but we are still waiting for the latest (exciting, much larger sample, 90 participants this time) study to be published. The research proposal describes the method in great detail, and you can read that with one click over on PubMed:
It was approved, and has now been completed (as of 2020), but the results have not been published yet; you can see the timeline of how that’s progressing over on ClinicalTrials.gov:
Clinical Trials | Ageing as a Mindset: A Counterclockwise Experiment to Rejuvenate Older Adults
Hopefully it’ll take less time than the eleven years it took for the original study, but in the meantime, there seems to be nothing to lose in doing a little “Citizen Science” for ourselves.
Maybe a week in a 20 years-ago themed resort (writer’s note: wow, that would only be 2004; that doesn’t feel right; it should surely be at least the 90s!) isn’t a viable option for you, but we’re willing to bet it’s possible to “microdose” on this method. Given that the original study lasted only a week, even just a themed date-night on a regular recurring basis seems like a great option to explore (if you’re not partnered then well, indulge yourself how best you see fit, in accord with the same premise; a date-night can be with yourself too!).
Just remember the most important take-away though:
Don’t accidentally put yourself in your own control group!
In other words, it’s critically important that for the duration of the exercise, you act and even think as though it is the appropriate date.
If you instead spend your time thinking “wow, I miss the [decade that does it for you]”, you will dodge the benefits, and potentially even make yourself feel (and thus, potentially, if the inverse hypothesis holds true, become) older.
This latter is not just our hypothesis by the way, there is an established potential for nocebo effect.
For example, the following study looked at how instructions given in clinical tests can be worded in a way that make people feel differently about their age, and impact the results of the mental and/or physical tests then administered:
❝Our results seem to suggest how manipulations by instructions appeared to be more largely used and capable of producing more clear performance variations on cognitive, memory, and physical tasks.
Age-related stereotypes showed potentially stronger effects when they are negative, implicit, and temporally closer to the test of performance. ❞
(and yes, that’s the same Dr. Francesco Pagnini whose name you saw atop the other study we cited above, with the 90 participants recreating the Counterclockwise study)

Fruit & Veg In The Fridge: Pros & Cons

It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
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
❝What effect does refrigeration have on the nutritional value of fruit and vegetables??❞
It’s difficult to give a single definitive answer, because naturally there are a lot of different fruits and vegetables, and a lot of different climates. The answer may be different for tomatoes in Alaska vs bananas in Arizona!
However, we can still generalize at least somewhat
Refrigeration will generally slow down any degradation process, and in the case of fruit and vegetables, that can mean slowing down their “ripening” too, as applicable.
However…
Refrigeration will also impede helpful bioactivity too, and that includes quite a list of things.
Here’s a good study that’s quite illustrative; we’d summarize the conclusions but the rather long title already does that nicely:
So, this really is a case of “there are pros and cons, but probably more cons on balance”.
In practical terms, a good take-away from this can be twofold:
- don’t keep fruit and veg in the fridge unless the ambient temperature really requires it
- if the ambient temperature does require it, it’s best to get the produce in fresh each day if that’s feasible, to minimize time spent in the fridge
An extra thing not included there: often when it comes to the spoilage of fruit and veg, the problem is that it respires and oxidizes; reducing the temperature does lower the rate of those, but often a far better way is to remove the oxygen. So for example, if you get carried away and chop too many carrot batons for your hummus night, then putting them in a sealed container can go a long way to keeping them fresh.

It’s On Me – by Dr. Sara Kuburic

This isn’t about bootstrapping and nor is it a motivational pep talk. What it is, however, is a wake-up call for the wayward, and that doesn’t mean “disaffected youth” or such. Rather, therapist Dr. Sara Kuburic tackles the problem of self-loss.
It’s about when we get so caught up in what we need to do, should do, are expected to do, are in a rut of doing… That we forget to also live. After all, we only get one shot at life so far as we know, so we might as well live it in whatever way is right for us.
That probably doesn’t mean a life of going through the motions.
The writing style here is personal and direct, and it makes for quite compelling reading from start to finish.
Bottom line: if ever you find yourself errantly sleepwalking through life and would like to change that, this is a book for you.

Never Enough – by Dr. Judith Grisel
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’ve reviewed books about addiction before—specifically about alcohol, at least. This one’s more general in that it covers different addictions.
On the other hand, it’s also more specific, in that it covers them from the author’s field: neuroscience.
…and experience too. The author had a plethora of addictions (the serious kind), got sober, and then undertook to study neuroscience. Her hope was to help others avoid, or escape from the same as‚ what she went through.
Dr. Grisel (as she now is) takes a methodical approach in this book. She works her way through the addictive mechanisms of a broad selection of common drugs, explaining each.
The focus here is on neutral explanations, rather than the propagandizing scaremongering that failed at least one generation. Why each drug is alluring, what it really does do—and the neurological price it exacts, down to the molecular level.
She also covers risk factors for addiction; genetic, epigenetic, and environmental. There’s no “if you were stronger”, or “these people made bad choices”, so much as… Many addicts were, in effect, sabotaged from before birth.
That doesn’t mean that to become addicted or not is just fate, but it does mean… There but for the grace of factors completely outside of our control go we.
Why is this useful to us, be we a reader without any meaningful addiction (we’re not counting coffee etc here)? Well, as this book illustrates and explains, many of us could be one (more) mishap away from a crippling addiction and not know it. Forewarned is forearmed.
Bottom line: almost all of us are, have been, or will be touched by addiction in some way. Either directly, or a loved one, or a loved one’s loved one, or perhaps a parent who gave us an epigenetic misfortune. This book gives understanding that can help.

Red-dy For Anything Polyphenol Salad
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.
So, you’ve enjoyed your Supergreen Superfood Salad Slaw, and now you’re ready for another slice of the rainbow. Pigments in food aren’t just for decoration—they each contain unique benefits! Today’s focus is on some red foods that, combined, make a deliciously refreshing salad that’s great for the gut, heart, and brain.
You will need
- 1 cup crème fraîche or sour cream (if vegan, use our Plant-Based Healthy Cream Cheese recipe, and add the juice of 1 lime)
- ½ small red cabbage, thinly sliced
- 1 red apple, cored and finely chopped
- 1 red onion, thinly sliced
- 10 oz red seedless grapes, halved
- 10 oz red pomegranate seeds
- 1 tsp red chili flakes
Method
(we suggest you read everything at least once before doing anything)
1) Combine all the red ingredients in a big bowl.
2) Add the crème fraîche and mix gently but thoroughly.
3) If you have time, let it sit in the fridge for 48 hours before enjoying, as its colors will intensify and its polyphenols will become more bioavailable. But if you want/need, you can serve immediately; that’s fine too.
Enjoy!

Clams vs Oysters – 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 clams to oysters, we picked the clams.
Why?
Considering the macros first, clams have more than 2x the protein, while oysters have nearly 2x the fat, of which, a little over 5x the saturated fat. So, in all accounts, clam is the winner here.
In terms of vitamins, clams have more of vitamins A, B1, B2, B3, B5, B6, B7, B9, B12, and C, while oysters are not higher in any vitamins. Another win for clams.
The category of minerals is more balanced; clams are higher in manganese, phosphorus, potassium, and selenium, while oysters are higher in copper, iron, magnesium, and zinc. This makes for a 4:4 tie, though it’s worth noting that the margin of difference for zinc is very large, so that can be an argument for oysters.
Nevertheless, adding up the sections makes for a clear win for clams.
A quick aside on “are oysters an aphrodisiac?”:
That zinc content is probably largely responsible for oysters’ reputation as an aphrodisiac, and zinc is important in the synthesis of both estrogen and testosterone. However, as the synthesis is not instant, and those sex hormones rise most in the morning (around 8am to 9am), to enjoy aphrodisiac benefits it’d be more sensible, on a biochemical level, to eat oysters one day, and then have morning sex the next day when those hormones are peaking. That said, while testosterone is the main driver of male libido, progesterone is usually more relevant for women’s, and unlike estrogen, progesterone usually peaks around 10pm to 2am, and is uninfluenced by having just eaten oysters.
So, in what way, if any, could oysters be responsible for libido in women? Well, the zinc is still important in energy metabolism, so that’s a factor, and also, we might hypothesize that oysters’ high saturated fat and cholesterol content may increase blood pressure which, while not fabulous for the health in general, may be considered desirable in the bedroom since the clitoris is anatomically analogous to the penis, and—while estrogen vs testosterone makes differences to the nervous system down there that are beyond the scope of today’s article—also enjoys localized increased blood pressure (and thus, a flushing response and resultant engorgement) during arousal.
