Our Verdict
When comparing cucumber to lychee, we picked the lychee.
Why?
In terms of macros, the lychee has more carbs and more fiber, but both are low glycemic index foods. Functionally a tie, though we could consider it a nominal win for cucumber.
In the category of vitamins, cucumber has more of vitamins A, B1, B5, and K, while lychee has more of vitamins B2, B3, B6, B9, C, E, and choline. In particular, cucumber has a lot more vitamin K and lychee has a lot more vitamin C. Nevertheless, in terms of overall vitamin coverage, lychee is the clear winner here.
Looking at minerals, cucumber has more calcium, magnesium, manganese, and zinc, while lychee has more copper (especially rich in this), iron, phosphorus, potassium, and selenium. Another clear win for lychee.
Both have an abundance of anti-inflammatory polyphenols, but we could find no strong argument for one being better than the other in this category, just different.
In short, both are fine options, but the more nutritionally dense is the lychee, so that’s our choice!

Eating Disorders: More Varied (And Prevalent) Than People Think
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.
Disordered Eating Beyond The Stereotypes
Around 10% of Americans* have (or have had) an eating disorder. That might not seem like a high percentage, but that’s one in ten; do you know 10 people? If so, it might be a topic that’s near to you.
*Source: Social and economic cost of eating disorders in the United States of Americ
Our hope is that even if you yourself have never had such a problem in your life, today’s article will help arm you with knowledge. You never know who in your life might need your support.
Very misunderstood
Eating disorders are so widely misunderstood in so many ways that we nearly made this a Friday Mythbusting edition—but we preface those with a poll that we hope to be at least somewhat polarizing or provide a spectrum of belief. In this case, meanwhile, there’s a whole cluster of myths that cannot be summed up in one question. So, here we are doing a Psychology Sunday edition instead.
“Eating disorders aren’t that important”
Eating disorders are the second most deadly category of mental illness, second only to opioid addiction.
Anorexia specifically has the highest case mortality rate of any mental illness:
Source: National Association of Anorexia Nervosa & Associated Disorders: Eating Disorder Statistics
So please, if someone needs help with an eating disorder (including if it’s you), help them.
“Eating disorders are for angsty rebellious teens”
While there’s often an element of “this is the one thing I can control” to some eating disorders (including anorexia and bulimia), eating disorders very often present in early middle-age, very often amongst busy career-driven individuals using it as a coping mechanism to have a feeling of control in their hectic lives.
13% of women over 50 report current core eating disorder symptoms, and that is probably underreported.
Source: as above; scroll to near the bottom!
“Eating disorders are a female thing”
Nope. Officially, men represent around 25% of people diagnosed with eating disorders, but women are 5x more likely to get diagnosed, so you can do the math there. Women are also 1.5% more likely to receive treatment for it.
By the time men do get diagnosed, they’ve often done a lot more damage to their bodies because they, as well as other people, have overlooked the possibility of their eating being disordered, due to the stereotype of it being a female thing.
Source: as above again!
“Eating disorders are about body image”
They can be, but that’s far from the only kind!
Some can be about control of diet, not just for the sake of controlling one’s body, but purely for the sake of controlling the diet itself.
Still yet others can be not about body image or control, like “Avoidant/Restrictive Food Intake Disorder”, which in lay terms sometimes gets dismissed as “being a picky eater” or simply “losing one’s appetite”, but can be serious.
For example, a common presentation of the latter might be a person who is racked with guilt and/or anxiety, and simply stops eating, because either they don’t feel they deserve it, or “how can I eat at a time like this, when…?” but the time is an ongoing thing so their impromptu fast is too.
Still yet even more others might be about trying to regulate emotions by (in essence) self-medicating with food—not in the healthy “so eat some fruit and veg and nuts etc” sense, but in the “Binge-Eating Disorder” sense.
And that latter accounts for a lot of adults.
You can read more about these things here:

Take care! And if you have, or think you might have, an eating disorder, know that there are organizations that can and will offer help/support in a non-judgmental fashion. Here’s the ANAD’s eating disorder help resource page, for example.

Magic mushrooms may one day treat anorexia, but not just yet
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.
Anorexia nervosa is a severe mental health disorder where people fear weight gain. Those with the disorder have distorted body image and hold rigid beliefs their body is too big. They typically manage this through restricted eating, leading to the serious medical consequences of malnutrition.
Anorexia has one of the highest death rates of any mental illness. Yet there are currently no effective drug treatments and the outcomes of psychotherapy (talk therapy) are poor. So we’re desperately in need of new and improved treatments.
Psilocybin, commonly known as magic mushrooms, is one such novel treatment. But while it shows early promise, you won’t see it used in clinical practice just yet – more research is needed to test if it’s safe and effective.
Ground Picture/Shutterstock What does treatment involve?
The treatment involves the patient taking a dose of psilocybin in a safe environment, which is usually a specifically set up clinic. The patient undergoes preparation therapy before the dosing session and integration therapy after.
Psilocybin, extracted from mushrooms, is a psychedelic, which means it can produce altered thinking, sense of time and emotions, and can often result in hallucinations. It also has the potential to shift patients out of their rigid thinking patterns.
Psilocybin is not administered alone but instead with combined structured psychotherapy sessions to help the patient make sense of their experiences and the changes to their thinking. This is an important part of the treatment.
What does the research show?
Research has shown improved effects of psilocybin-assisted psychotherapy after one or two dosing sessions, a couple of weeks apart. Most research to date has targeted depression.
Psilocybin has been found to increase cognitive flexibility – our ability to adjust our thinking patterns according to changing environments or demands. This is one of the ways researchers believe psilocybin might improve symptoms for conditions such as depression and alcohol use disorder, which are marked by rigid thinking styles.
People with anorexia similarly struggle with rigid thinking patterns. So researchers and clinicians have recently turned their attention to anorexia.
In 2023, a small pilot study of ten women with anorexia was published in the journal Nature Medicine. It showed psilocybin-assisted psychotherapy (with 25mg of psilocybin) was safe and acceptable. There were no significant side effects and participants reported having valuable experiences.
Although the trial was not a formal efficacy trial, 40% of the patients did have significant drops in their eating disorder behaviour.
However, the trial only had one dosing session and no long-term follow up, so further research is needed.
Researchers are still working out dosages and frequency. 24K-Production/Shutterstock A recent animal study using rats examined whether rigid thinking could be improved in rats when given psilocybin. After the psilocybin, rats gained weight and had more flexible thinking (using a reversal learning task).
These positive changes were related to the serotonin neurotransmitter system, which regulates mood, behaviour and satiety (feeling full).
Brain imaging studies in humans show serotonin disturbances in people with anorexia. Psilocybin-assisted psychotherapy is showing promise at modifying the serotonin disturbances and cognitive inflexibility that have been shown to be problematic in anorexia.
Research with animals can provide unique insights into the brain which can sometimes not be investigated in living humans. But animal models can never truly mimic human behaviour and the complex nature of chronic mental health conditions.
What’s next for research?
Further clinical trials in humans are very much needed – and are underway from a research team at the University of Sydney and ours at Swinburne.
Our trial will involve an initial 5mg dose followed by two subsequent doses of 25mg, several weeks apart. An initial low dose aims to help participants prepare for what is likely to be a new and somewhat unpredictable experience.
Our trial will examine the usefulness of providing psychotherapy that directly addresses body image disturbance. We are also investigating if including a family member or close friend in the treatment increases support for their loved one.
We’re investigating whether including a family member or close friend in treatment could help. Shutterstock Data from other mental health conditions has suggested that not everyone sees benefits, with some people having bad trips and a deterioration in their mental health. So this treatment won’t be for everyone. It’s important to work out who is most likely to respond and under what conditions.
New trials and those underway will be critical in understanding whether psilocybin-assisted psychotherapy is a safe and effective treatment for anorexia, and the optimal conditions to improve the patient’s response. But we are some way off from seeing this treatment in the clinic. One of the big issues being the cost of this intervention and how this will be funded.

Do We Need Supplements, And Do They Work?
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.
Does our diet need a little help?
We asked you for your take on supplements, and got the above-illustrated, below-described set of results.
- The largest minority of respondents (a little over a third) voted for “I just take something very specific”
- The next most respondents voted for “I take so many supplements; every little helps!”
- Almost as many voted for “I just take a vitamin or two / a multivitamin”
- Fewest, about 8%, voted for “I get everything I need from my diet”
But what does the science say?
Food is less nutritious now than it used to be: True or False?
True or False depending on how you measure it.
An apple today and an apple from a hundred years ago are likely to contain the same amounts of micronutrients per apple, but a lower percentage of micronutrients per 100g of apple.
The reason for this is that apples (and many other food products; apples are just an arbitrary example) have been selectively bred (and in some cases, modified) for size, and because the soil mineral density has remained the same, the micronutrients per apple have not increased commensurate to the increase in carbohydrate weight and/or water weight. Thus, the resultant percentage will be lower, despite the quantity remaining the same.
We’re going to share some science on this, and/but would like to forewarn readers that the language of this paper is a bit biased, as it looks to “debunk” claims of nutritional values dropping while skimming over “yes, they really have dropped percentage-wise” in favor of “but look, the discrete mass values are still the same, so that’s just a mathematical illusion”.
The reality is, it’s no more a mathematical illusion than is the converse standpoint of saying the nutritional value is the same, despite the per-100g values dropping. After all, sometimes we eat an apple as-is; sometimes we buy a bag of frozen chopped fruit. That 500g bag of chopped fruit is going to contain less copper (for example) than one from decades past.
Here’s the paper, and you’ll see what we mean:
Supplements aren’t absorbed properly and thus are a waste of money: True or False?
True or False depending on the supplement (and your body, and the rest of your diet)
Many people are suffering from dietary deficiencies of vitamins and minerals, that could be easily correctable by supplementation:
However, as this study by Dr. Fang Fang Zhang shows, a lot of vitamin and mineral supplementation does not appear to have much of an effect on actual health outcomes, vis-à-vis specific diseases. She looks at:
- Cardiovascular disease
- Cancer
- Type 2 diabetes
- Osteoporosis
Her key take-aways from this study were:
- Randomised trial evidence does not support use of vitamin, mineral, and fish oil supplements to reduce the risk of non-communicable diseases
- People using supplements tend to be older, female, and have higher education, income, and healthier lifestyles than people who do not use them
- Use of supplements appreciably reduces the prevalence of inadequate intake for most nutrients but also increases the prevalence of excess intake for some nutrients
- Further research is needed to assess the long term effects of supplements on the health of the general population and in individuals with specific nutritional needs, including those from low and middle income countries
Read her damning report: Health effects of vitamin and mineral supplements
On the other hand…
This is almost entirely about blanket vitamin-and-mineral supplementation. With regard to fish oil supplementation, many commercial fish oil supplements break down in the stomach rather than the intestines, and don’t get absorbed well. Additionally, many people take them in forms that aren’t pleasant, and thus result in low adherence (i.e., they nominally take them, but in fact they just sit on the kitchen counter for a year).
One thing we can conclude from this is that it’s good to check the science for any given supplement before taking it, and know what it will and won’t help for. Our “Monday Research Review” editions of 10almonds do this a lot, although we tend to focus on herbal supplements rather than vitamins and minerals.
We can get everything we need from our diet: True or False?
Contingently True (but here be caveats)
In principle, if we eat the recommended guideline amounts of various macro- and micro-nutrients, we will indeed get all that we are generally considered to need. Obviously.
However, this may come with:
- Make sure to get enough protein… Without too much meat, and also without too much carbohydrate, such as from most plant sources of protein
- Make sure to get enough carbohydrates… But only the right kinds, and not too much, nor at the wrong time, and without eating things in the wrong order
- Make sure to get enough healthy fats… Without too much of the unhealthy fats that often exist in the same foods
- Make sure to get the right amount of vitamins and minerals… We hope you have your calculators out to get the delicate balance of calcium, magnesium, potassium, phosphorus, and vitamin D right.
That last one’s a real pain, by the way. Too much or too little of one or another and the whole set start causing problems, and several of them interact with several others, and/or compete for resources, and/or are needed for the others to do their job.
And, that’s hard enough to balance when you’re taking supplements with the mg/µg amount written on them, never mind when you’re juggling cabbages and sardines.
On the topic of those sardines, don’t forget to carefully balance your omega-3, -6, and -9, and even within omega-3, balancing ALA, EPA, and DHA, and we hope you’re juggling those HDL and LDL levels too.
So, when it comes to getting everything we need from our diet, for most of us (who aren’t living in food deserts and/or experiencing food poverty, or having a medical condition that restricts our diet), the biggest task is not “getting enough”, it’s “getting enough of the right things without simultaneously overdoing it on the others”.
With supplements, it’s a lot easier to control what we’re putting in our bodies.
And of course, unless our diet includes things that usually can’t be bought in supermarkets, we’re not going to get the benefits of taking, as a supplement, such things as:
Etc.
So, there definitely are supplements with strong science-backed benefits, that probably can’t be found on your plate!

Dopamine Nation – by Dr. Anna Lembke
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 live in an age of abundance, though it often doesn’t feel like it. Some of that is due to artificial scarcity, but a lot of it is due to effectively whiting out our dopamine circuitry through chronic overuse.
Psychiatrist Dr. Anna Lembke explores the neurophysiology of pleasure and pain, and how each can (and does) lead to the other. Is the answer to lead a life of extreme neutrality? Not quite.
Rather, simply by being more mindful of how we seek each (yes, both pleasure and pain), we can leverage our neurophysiology to live a better, healthier life—and break/avoid compulsive habits, while we’re at it.
That said, the book itself is quite compelling reading, but as Dr. Lembke shows us, that certainly doesn’t have to be a bad thing.
Bottom line: if you sometimes find yourself restlessly cycling through the same few apps (or TV channels) looking for dopamine that you’re not going to find there, this is the book for you.

Kidney Beans vs Fava Beans – 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 kidney beans to fava beans, we picked the kidney beans.
Why?
It’s a simple and straightforward one today!
The macronutrient profiles are mostly comparable, but kidney beans do have a little more protein and a little more fiber.
In the category of vitamins, kidney beans have more of vitamins B1, B5, B6, B9, C, E, & K, while fava beans boast only more of vitamins B2 and B3. They are both equally good sources of choline, but the general weight of vitamins is very much in kidney beans’ favor, with a 7:2 lead, most of which have generous margins.
When it comes to minerals, kidney beans have more iron, phosphorus, and potassium, while fava beans have more copper and selenium. They’re both equally good sources of other minerals they both contain. Still, a 3:2 victory for kidney beans on the mineral front.
Adding up the moderate victory on macros, the strong victory on vitamins, and the slight victory on minerals, all in all makes for a clear win for kidney beans.
Still, enjoy both! Diversity is healthy.

Cordyceps: Friend Or Foe?
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.
Cordyceps: friend or foe?
Cordyceps is a famously frightening fungus. It’s the one responsible for “zombie ants” and other zombie creatures, and it’s the basis for the existential threat to humanity in the TV show The Last of Us.
It’s a parasitic fungus that controls the central and peripheral nervous systems of its host, slowly replacing the host’s body, as well as growing distinctive spines that erupt out of the host’s body. Taking over motor functions, it compels the host to do two main things, which are to eat more food, and climb to a position that will be good to release spores from.
Fortunately, none of that matters to humans. Cordyceps does not (unlike in the TV show) affect humans that way.
What does Cordyceps do in humans?
Cordyceps (in various strains) is enjoyed as a health supplement, based on a long history of use in Traditional Chinese Medicine, and nowadays it’s coming under a scientific spotlight too.
The main health claims for it are:
- Against inflammation
- Against aging
- Against cancer
- For blood sugar management
- For heart health
- For exercise performance
Sounds great! What does the science say?
There’s a lot more science for the first three (which are all closely related to each other, and often overlapping in mechanism and effect).
So let’s take a look:
Against inflammation
The science looks promising for this, but studies so far have either been in vitro (cell cultures in petri dishes), or else murine in vivo (mouse studies), for example:
- Anti-inflammatory effects of Cordyceps mycelium in murine macrophages
- Cordyceps sinensis as an immunomodulatory agent
- Immunomodulatory functions of extracts from Cordyceps cicadae
- Cordyceps pruinosa inhibits in vitro and in vivo inflammatory mediators
In summary: we can see that it has anti-inflammatory properties for mice and in the lab; we’d love to see the results of studies done on humans, though. Also, while it has anti-inflammatory properties, it performed less well than commonly-prescribed anti-inflammatory drugs, for example:
❝C. militaris can modulate airway inflammation in asthma, but it is less effective than prednisolone or montelukast.❞
Against aging
Because examining the anti-aging effects of a substance requires measuring lifespans and repeating the experiment, anti-aging studies do not tend to be done on humans, because they would take lifetimes to perform. To this end, it’s inconvenient, but not a criticism of Cordyceps, that studies have been either mouse studies (short lifespan, mammals like us) or fruit fly studies (very short lifespan, genetically surprisingly similar to us).
The studies have had positive results, with typical lifespan extensions of 15–20%:
- The lifespan-extending effect of Cordyceps sinensis in normal mice
- Cordyceps sinensis oral liquid prolongs the lifespan of the fruit fly, Drosophila melanogaster
- Anti-aging activity of polysaccharides from Cordyceps militaris
- Anti-aging effect of Cordyceps sinensis extract
Against cancer
Once again, the studies here have been in vitro, or murine in vivo. They do look good though:
In vitro (human cell cultures in a lab):
In vivo (mouse studies):
Summary of these is: Cordyceps quite reliably inhibits tumor growth in vitro (human cell cultures) and in vivo (mouse studies). However, trials in human cancer patients are so far conspicuous by their absence.
For blood sugar management
Cordyceps appears to mimic the action of insulin, without triggering insulin sensitivity. For example:
The anti-hyperglycemic activity of the fruiting body of Cordyceps in diabetic rats
There were some other rat/mouse studies with similar results. No studies in humans yet.
For heart health
Cordyceps contains adenosine. You may remember that caffeine owes part of its stimulant effect to blocking adenosine, the hormone that makes us feel sleepy. So in this way, Cordyceps partially does the opposite of what caffeine does, and may be useful against arrhythmia:
Cardiovascular protection of Cordyceps sinensis act partially via adenosine receptors
For exercise performance
A small (30 elderly participants) study found that Cordyceps supplementation improved VO2 max by 7% over the course of six weeks:
However, another small study (22 young athletes) failed to reproduce those results:
Cordyceps Sinensis supplementation does not improve endurance exercise performance
In summary…
Cordyceps almost certainly has anti-inflammation, anti-aging, and anti-cancer benefits.
Cordyceps may have other benefits too, but the evidence is thinner on the ground for those, so far.
