Does It Come In A Pill?
For any as yet unfamiliar with the Mediterranean diet, you may be wondering what it involves, beyond a general expectation that it’s a diet popularly enjoyed in the Mediterranean. What image comes to mind?
We’re willing to bet that tomatoes feature (great source of lycopene, by the way, and if you’re not getting lycopene, you’re missing out), but what else?
- Salads, perhaps? Vegetables, olives? Olive oil, yea or nay?
- Bread? Pasta? Prosciutto, salami? Cheese?
- Pizza but only if it’s Romana style, not Chicago?
- Pan-seared liver, with some fava beans and a nice Chianti?
In fact, the Mediterranean diet is quite clear on all these questions, so to read about these and more (including a “this yes, that no” list), see:
What Is The Mediterranean Diet, And What Is It Good For?
So, how do we get that in a pill?
A plucky band of researchers, Dr. Chiara de Lucia et al. (quite a lot of “et al.”; nine listed authors on the study), wondered to what extent the benefits of the Mediterranean diet come from the fact that the Mediterranean diet is very rich in polyphenols, and set about testing that, by putting the same polyphenols in capsule form, and running a randomized, double-blind, placebo-controlled, crossover clinical intervention trial.
Now, polyphenols are not the only reason the Mediterranean diet is great; there are also other considerations, such as:
- a great macronutrient balance with lots of fiber, healthy fats, moderate carbs, and protein from select sources
- the absence or at least very low presence of a lot of harmful substances such as refined seed oils, added sugars, refined carbohydrates, and the like (“but pasta” yes pasta; in moderation and wholegrain and served with extra sources of fiber and healthy fats, all of which slow down the absorption of the carbs)
…but polyphenols are admittedly very important too; we wrote about some common aspects of them here:
Tasty Polyphenols: Enjoy Bitter Foods For Your Heart & Brain
As for what Dr. de Lucia et al. put into the capsule, behold…
The ingredients:
- Apple Extract 10.0%
- Pomegranate Extract 10.0%
- Tomato Powder 2.5%
- Beet, Spray Dried 2.5%
- Olive Extract 7.5%
- Rosemary Extract 7.5%
- Green Coffee Bean Extract (CA) 7.5%
- Kale, Freeze Dried 2.5%
- Onion Extract 10.0%
- Ginger Extract 10.0%
- Grapefruit Extract 2.5%
- Carrot, Air Dried 2.5%
- Grape Skin Extract 17.5%
- Blueberry Extract 2.5%
- Currant, Freeze Dried 2.5%
- Elderberry, Freeze Dried 2.5%
And the relevant phytochemicals they contain:
- Quercetin
- Luteolin
- Catechins
- Punicalagins
- Phloretin
- Ellagic Acid
- Naringin
- Apigenin
- Isorhamnetin
- Chlorogenic Acids
- Rosmarinic Acid
- Anthocyanins
- Kaempferol
- Proanthocyanidins
- Myricetin
- Betanin
And what, you may wonder, did they find? Well, first let’s briefly summarise the setup of the study:
They took volunteers (n=30), average age 67, BMI >25, without serious health complaints, not taking other supplements, not vegetarian or vegan, not consuming >5 cups of coffee per day, and various other stipulations like that, to create a fairly homogenous study group who were expected to respond well to the intervention. In contrast, someone who takes antioxidant supplements, already eats many different color plants per day, and drinks 10 cups of coffee, probably already has a lot of antioxidant activity going on, and someone with a lower BMI will generally have lower resting levels of inflammatory markers, so it’s harder to see a change, proportionally.
About those inflammatory markers: that’s what they were testing, to see whether the intervention “worked”; essentially, did the levels of inflammatory markers go up or down (up is bad; down is good).
For more on inflammation, by the way, see:
How to Prevent (or Reduce) Inflammation
…which also explains what it actually is, and some important nuances about it.
Back to the study…
They gave half the participants the supplement for a week and the other half placebo; had a week’s gap as a “washout”, then repeated it, switching the groups, taking blood samples before and after each stage.
What they found:
The group taking the supplement had lower inflammatory markers after a week of taking it, while the group taking the placebo had relatively higher inflammatory markers after a week of taking it; this trend was preserved across both groups (i.e., when they switched roles for the second half).
The results were very significant (p=0.01 or thereabouts), and yet at the same time, quite modest (i.e. the supplement made a very reliable, very small difference), probably because of the small dose (150mg) and small intervention period (1 week).
What the researchers concluded from this
The researchers concluded that this was a success; the study had been primarily to provide proof of principle, not to rock the world. Now they want the experiment to be repeated with larger sample sizes, greater heterogeneity, larger doses, and longer intervention periods.
This is all very reasonable and good science.
What we conclude from this
That ingredients list makes for a good shopping list!
Well, not the extracts they listed, necessarily, but rather those actual fruits, vegetables, etc.
If nine top scientists (anti-aging specialists, neurobiologists, pharmacologists, and at least one professor of applied statistics) came to the conclusion that to get the absolute most bang-for-buck possible, those are the plants to get the phytochemicals from, then we’re not going to ignore that.
So, take another list above and ask yourself: how many of those 16 foods do you eat regularly, and could you work the others in?
Want to make your Mediterranean diet even better?
While the Mediterranean diet is a top-tier catch-all, it can be tweaked for specific areas of health, for example giving it an extra focus on heart health, or brain health, or being anti-inflammatory, or being especially gut healthy:

What should I do if I can’t see a psychiatrist?
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.
People presenting at emergency with mental health concerns are experiencing the longest wait times in Australia for admission to a ward, according to a new report from the Australasian College of Emergency Medicine.
But with half of New South Wales’ public psychiatrists set to resign next week after ongoing pay disputes – and amid national shortages in the mental health workforce – Australians who rely on psychiatry support may be wondering where else to go.
If you can’t get in to see a psychiatrist and you need help, there are some other options. However in an emergency, you should call 000.
Why do people see a psychiatrist?
Psychiatrists are doctors who specialise in mental health and can prescribe medication.
People seek or require psychiatry support for many reasons. These may include:
- severe depression, including suicidal thoughts or behaviours
- severe anxiety, panic attacks or phobias
- post-traumatic stress disorder (PTSD)
- eating disorders, such as anorexia or bulimia
- attention deficit hyperactivity disorder (ADHD).
Psychiatrists complement other mental health clinicians by prescribing certain medications and making decisions about hospital admission. But when psychiatry support is not available a range of team members can contribute to a person’s mental health care.
Can my GP help?
Depending on your mental health concerns, your GP may be able to offer alternatives while you await formal psychiatry care.
GPs provide support for a range of mental health concerns, regardless of formal diagnosis. They can help address the causes and impact of issues including mental distress, changes in sleep, thinking, mood or behaviour.
The GP Psychiatry Support Line also provides doctors advice on care, prescription medication and how support can work.
It’s a good idea to book a long consult and consider taking a trusted person. Be explicit about how you’ve been feeling and what previous supports or medication you’ve accessed.
What about psychologists, counsellors or community services?
Your GP should also be aware of supports available locally and online.
For example, Head to Health is a government initiative, including information, a nationwide phone line, and in-person clinics in Victoria. It aims to improve mental health advice, assessment and access to treatment.
Medicare Mental Health Centres provide in-person care and are expanding across Australia.
There are also virtual care services in some areas. This includes advice on individualised assessment including whether to go to hospital.
Some community groups are led by peers rather than clinicians, such as Alternatives to Suicide.
How about if I’m rural or regional?
Accessing support in rural or regional areas is particularly tough.
Beyond helplines and formal supports, other options include local Suicide Prevention Networks and community initiatives such as ifarmwell and Men’s sheds.
Should I go to emergency?
As the new report shows, people who present at hospital emergency departments for mental health should expect long wait times before being admitted to a ward.
But going to a hospital emergency department will be essential for some who are experiencing a physical or mental health crisis.
Managing suicide-related distress
With the mass resignation of NSW psychiatrists looming, and amid shortages and blown-out emergency waiting times, people in suicide-related distress must receive the best available care and support.
Roughly nine Australians die by suicide each day. One in six have had thoughts of suicide at some point in their lives.
Suicidal thoughts can pass. There are evidence-based strategies people can immediately turn to when distressed and in need of ongoing care.
Safety planning is a popular suicide prevention strategy to help you stay safe.
What is a safety plan?
This is a personalised, step-by-step plan to remain safe during the onset or worsening of suicidal urges.
You can develop a safety plan collaboratively with a clinician and/or peer worker, or with loved ones. You can also make one on your own – many people like to use the Beyond Now app.
Safety plans usually include:
- recognising personal warning signs of a crisis (for example, feeling like a burden)
- identifying and using internal coping strategies (such as distracting yourself by listening to favourite music)
- seeking social supports for distraction (for example, visiting your local library)
- letting trusted family or friends know how you’re feeling – ideally, they should know they’re in your safety plan
- knowing contact details of specific mental health services (your GP, mental health supports, local hospital)
- making the environment safer by removing or limiting access to lethal means
- identifying specific and personalised reasons for living.
Our research shows safety planning is linked to reduced suicidal thoughts and behaviour, as well as feelings of depression and hopelessness, among adults.
Evidence from people with lived experience shows safety planning helps people to understand their warning signs and practice coping strategies.
Sharing your safety plan with loved ones may help understand warning signs of a crisis. Dragana Gordic/Shutterstock Are there helplines I can call?
There are people ready to listen, by phone or online chat, Australia-wide. You can try any of the following (most are available 24 hours a day, seven days a week):
Suicide helplines:
- Lifeline 13 11 14
- Suicide Call Back Service 1300 659 467
There is also specialised support:
- for men: MensLine Australia 1300 78 99 78
- children and young people: Kids’ Helpline 1800 55 1800
- Aboriginal and Torres Strait Islander people: 13YARN 13 92 76
- veterans and their families: Open Arms 1800 011 046
- LGBTQIA+ community: QLife 1300 184 527
- new and expecting parents: PANDA 1300 726 306
- people experiencing eating disorders: Butterfly Foundation 1800 33 4673.
Additionally, each state and territory will have its own list of mental health resources.
With uncertain access to services, it’s helpful to remember that there are people who care. You don’t have to go it alone.

Elderberries vs Gooseberries – 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 elderberries to gooseberries, we picked the elderberries.
Why?
These are both berries more likely found in your garden or local wood than in the supermarket, but if you have convenient access to them, they’re great options for eating!
In terms of macros, elderberry has nearly 2x the carbs and/but also nearly 2x the fiber, which in glycemic index terms, mostly cancels out (although: elderberry has the slightly lower glycemic index of the two)
In the category of vitamins, both are great but elderberries are winning with more of vitamins A, B1, B2, B3, B6, and C, while gooseberries have more vitamin B5.
When it comes to minerals, elderberries again lead with more calcium, iron, phosphorus, and potassium, while gooseberries have more magnesium.
There is an extra category today, which is “extra medicinal properties”, and elderberries have extra immune-boosting qualities, whereas gooseberries—while being as polyphenol-laden as one usually expects berries to be—do not confer the same kind of benefit in this regard.
You can check out the information about elderberry’s extra properties in the links section below; meanwhile, if you’re choosing between these berries, that’s the clear winner in every category today!

Turns out the viral ‘Sleepy Girl Mocktail’ is backed by science. Should you try it?
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 wish we could get a better night’s sleep. Wouldn’t it be great if it was as easy as a mocktail before bed?
That’s what the latest viral trend might have us believe. The “Sleepy Girl Mocktail” is a mix of tart cherry juice, powdered magnesium supplement and soda water. TikTok videos featuring the concoction have garnered hundreds of thousands of views. But, what does the science say? Do these ingredients actually help us sleep?
Tart cherry juice
There is research to show including tart cherry juice in your diet improves overall sleep. Clinical trials show tart cherry juice increases sleep quality and quantity, as well as a lessening insomnia symptoms (compared to a placebo). This could be due to the presence of melatonin, a sleep-promoting hormone, in cherries.
Tart cherry varieties such as Jerte Valley or Montmorency have the highest concentration of melatonin (approximately 0.135 micrograms of melatonin per 100g of cherry juice). Over the counter melatonin supplements can range from 0.5 milligram to over 100 milligrams, with research suggesting those beginning to take melatonin start with a dose of 0.5–2 milligrams to see an improvement in sleep.
Melatonin naturally occurs in our bodies. Our body clock promotes the release of melatonin in the evening to help us sleep, specifically in the two hours before our natural bedtime.
If we want to increase our melatonin intake with external sources, such as cherries, then we should be timing our intake with our natural increase in melatonin. Supplementing melatonin too close to bed will mean we may not get the sleep-promoting benefits in time to get off to sleep easily. Taking melatonin too late may even harm our long-term sleep health by sending the message to our body clock to delay the release of melatonin until later in the evening.
Magnesium – but how much?
Magnesium also works to promote melatonin, and magnesium supplements have been shown to improve sleep outcomes.
However, results vary depending on the amount of magnesium people take. And we don’t yet have the answers on the best dose of magnesium for sleep benefits.
We do know magnesium plays a vital role in energy production and bone development, making it an important daily nutrient for our diets. Foods rich in magnesium include wheat cereal or bread, almonds, cashews, pumpkin seeds, spinach, artichokes, green beans, soy milk and dark chocolate.
Bubbly water
Soda water serves as the base of the drink, rather than a pathway to better sleep. And bubbly water may make the mix more palatable. It is important to keep in mind that drinking fluids close to bedtime can be disruptive to our sleep as it might lead to waking during the night to urinate.
Healthy sleep recommendations include avoiding water intake in the two hours before bed. Having carbonated beverages too close to bed can also trigger digestive symptoms such as bloating, gassiness and reflux during the night.
Bottoms up?
Overall, there is evidence to support trying out the Sleepy Girl Mocktail to see if it improves sleep, however there are some key things to remember:
timing: to get the benefits of this drink, avoid having it too close to bed. Aim to have it two hours before your usual bedtime and avoid fluids after this time
consistency: no drink is going to be an immediate cure for poor sleep. However, this recipe could help promote sleep if used strategically (at the right time) and consistently as part of a balanced diet. It may also introduce a calming evening routine that helps your brain relax and signals it’s time for bed
- maximum magnesium: be mindful of the amount of magnesium you are consuming. While there are many health benefits to magnesium, the recommended daily maximum amounts are 420mg for adult males and 320mg for adult females. Exceeding the maximum can lead to low blood pressure, respiratory distress, stomach problems, muscle weakness and mood problems
sugar: in some of the TikTok recipes sugar (as flavoured sodas, syrups or lollies) is added to the drink. While this may help hide the taste of the tart cherry juice, the consumption of sugar too close to bed may make it more difficult to get to sleep. And sugar in the evening raises blood sugar levels at a time when our body is not primed to be processing sugar. Long term, this can increase our risk of diabetes
sleep environment: follow good sleep hygiene practices including keeping a consistent bedtime and wake time, a wind-down routine before bed, avoiding electronic device use like phones or laptops in bed, and avoiding bright light in the evening. Bright light works to suppress our melatonin levels in the evening and make us more alert.
What about other drinks?
Other common evening beverages include herbal tisanes or teas, hot chocolate, or warm milk.
Milk can be especially beneficial for sleep, as it contains the amino acid tryptophan, which can promote melatonin production. Again, it is important to also consider the timing of these drinks and to avoid any caffeine in tea and too much chocolate too close to bedtime, as this can make us more alert rather than sleepy.
Getting enough sleep is crucial to our health and wellbeing. If you have tried multiple strategies to improve your sleep and things are not getting better, it may be time to seek professional advice, such as from a GP.

Physical Sunscreen or Chemical Sunscreen – 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 physical sunscreens to chemical sunscreens, we picked the physical sunscreens.
Why?
It’s easy to vote against chemical sunscreens, because it has “chemical” in the name, which tends to be offputting PR-wise no matter how healthy something is.
But in this case, there’s actual science here too!
Physical sunscreens physically block the UV rays.
- On the simplest of levels, mud is a physical sunscreen, as you can see widely used by elephants, hippos, pigs, and other animals.
- On a more sophisticated level, modern physical sunscreens often use tiny zinc particles (or similar) to block the UV rays in a way that isn’t so obvious to the naked eye—so we can still see our skin, and it looks just like we applied an oil or other moisturizer.
Chemical sunscreens interact with the UV rays in a way that absorbs them.
- Specifically, they usually convert it into relatively harmless thermal energy (heat)
- However, this can cause problems if there’s too much heat!
- Additionally, chemical sunscreens can get “used up” in a way that physical sunscreens can’t* becoming effectively deactivated once the chemical reaction has run its course and there is no more reagent left unreacted.
- Worse, some of the reagents, when broken down by the UV rays, can potentially cause harm when absorbed by the skin.
*That said, physical sunscreens will still need “topping up” because we are a living organism and our body can’t resist redistributing and using stuff—plus, depending on the climate and our activities, we can lose some externally too.

Mind Gym – by Gary Mack and David Casstevens
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.
While this book seems to be mostly popular amongst young American college athletes and those around them (coaches, parents, etc) its applicability is a lot wider than that.
The thing is, as this book details, we don’t have to settle for less than optimal in our training—whatever “optimal” means for us, at any stage of life.
The style is largely narrative, and conveys a lot of ideas through anecdotes. They are probably true, but whether they occured entirely as-written or have been polished or embellished is not so important, as to to give food for thought, and reflection on how we can hone what we’re doing to work the best for us.
Nor is it just a long pep-talk, though it certainly has a motivational aspect. But rather, it covers also such things as the seven critical areas that we need to excel at if we want to be mentally robust, and—counterintuitively—the value of slowing down sometimes. The authors also talk about the importance of love, labor, and ongoing learning if we want a fulfilled life.
Bottom line: if you are engaged with any sport or sport-like endeavor that you’d like to be better at, this book will sharpen your training and development.

How To Manage Your Mood With Food (8 Ways)
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.
It is hard to be mentally healthy for long without good diet. Food can not only affect our mood directly, but also indirectly because of how our brain works (or doesn’t, if we don’t have the right nutrients, or it is being sabotaged in some other dietary fashion).
Selecting the food for setting the mood
Mind, the mental health charity, have these advices to share (with some bonus notes of our own):
- Eat regularly: blood sugar peaks and troughs can heighten feelings of tiredness, irritability, or depression. Instead, enjoy foods that are high in energy but low in glycemic index, such as nuts, seeds, and oats—that way you’ll have plenty of energy, that lasts longer.
- Choose the right fats: omega-3 fatty acids are essential for the brain. So are omega-6 fatty acids, but it is rare to have a deficiency in omega-6, and indeed, many people have the ratio of omega-3 to omega-6 far too imbalanced in omega-6’s favor. So, focussing on getting more omega-3 fatty acids is important. Nuts and seeds are again great, as are avocados, eggs, and oily fish.
- Get a healthy amount of protein: and importantly, with a good mix of amino acids—so a variety of sources of protein is best. In particular, if you are vegan, paying attention to ensure you get a full spread of amino acids is critical, as not many plants have all the ones we need (soy does, though). The reason this is important for mood is because many of those amino acids double up as the building blocks of neurotransmitters, so they’re not entirely interchangeable.
- Stay hydrated: our bodies are famously made of mostly water, and our brain will not work well if it’s dehydrated. The human body can squeeze water out of almost anything that has water in it, but water from food (such as fruit, or soups) is best. If enjoying actual drinks, then herbal teas are excellent for hydration.
- Eat a rainbow of fruits and vegetables: these have many nutrients that are important for brain health, and the point of the colors is that most of those pigments are themselves nutrients. Additionally, the fiber content of fruits and vegetables is of topmost important for your heart, and as you’ll remember (we say it often, because it’s true): what’s good for your heart is good for your brain.
- Limit caffeine intake: for many people, excess caffeine can lead to feelings of anxiety, disrupt your sleep, and for everyone who has developed an addiction to it, it will cause withdrawal symptoms if stopped abruptly. Cutting back on caffeine, or even eliminating it, may improve your mood and sleep quality. Note, however, that if you have ADHD, then your brain’s physiological relationship with caffeine is a little different, and stimulants will be more beneficial (and less deleterious) for you than for most people. If unsure, speak with your doctor about this one.
- Support your gut health: because of the gut-brain axis (via the vagal nerve), and also because nearly all of our endogenous serotonin is made in the gut (along with other neurotransmitters/hormones), getting plenty of fiber is important, and probiotics can help too.
- Consider food intolerances: if you know you have one, then keep that in mind and tailor your diet accordingly. If you suspect you have one, seek a nutritionist’s help to find out for sure. These can affect many aspects of health, including mood, so should not be dismissed as a triviality.
