❝In order to lose a little weight I have cut out cheese from my diet – and am finding that I am sleeping better. Would be interested in your views on cheese and sleep, and whether some types of cheese are worse for sleep than others. I don’t want to give up cheese entirely!❞
In principle, there’s nothing in cheese that, biochemically, should impair sleep. If anything, its tryptophan content could aid good sleep.
Tryptophan is found in many foods, including cheese, which (of common foods, anyway), for example cheddar cheese ranks second only to pumpkin seeds in tryptophan content.
Tryptophan can be converted by the body into 5-HTP, which you’ve maybe seen sold as a supplement. Its full name is 5-hydroxytryptophan.
5-HTP can, in turn, be used to make melatonin and/or serotonin. Which of those you will get more of, depends on what your body is being cued to do by ambient light/darkness, and other environmental cues.
If you are having cheese and then checking your phone, for instance, or otherwise hanging out where there are white/blue lights, then your body may dutifully convert the tryptophan into serotonin (calm wakefulness) instead of melatonin (drowsiness and sleep).
In short: the cheese will (in terms of this biochemical pathway, anyway) augment some sleep-inducing or wakefulness-inducing cues, depending on which are available.
You may be wondering: what about casein?
Casein is oft-touted as producing deep sleep, or disturbed sleep, or vivid dreams, or bad dreams. There’s no science to back any of this up, though the following research review is fascinating:
Dreams of the Rarebit Fiend: food and diet as instigators of bizarre and disturbing dreams
(it largely supports the null hypothesis of “not a causal factor” but does look at the many more likely alternative explanations, ranging from associated actually casual factors (such as alcohol and caffeine) and placebo/nocebo effect)
Finally, simple digestive issues may be the real thing at hand:
Worth noting that around two thirds of all people, including those who regularly enjoy dairy products, have some degree of lactose intolerance:
Lactose Intolerance in Adults: Biological Mechanism and Dietary Management
So, in terms of what cheese may be better/worse for you in this context, you might try experimenting with lactose-free cheese, which will help you identify whether that was the issue!

Olive oil is healthy. Turns out olive leaf extract may be good for us too
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.
Olive oil is synonymous with the Mediterranean diet, and the health benefits of both are well documented.
Olive oil reduces the risk of heart disease, cancer, diabetes and premature death. Olives also contain numerous healthy nutrients.
Now evidence is mounting about the health benefits of olive leaves, including from studies in a recent review.
Here’s what’s in olive leaves and who might benefit from taking olive leaf extract.
mtphoto19/Shutterstock What’s in olive leaves?
Olive leaves have traditionally been brewed as a tea in the Mediterranean and drunk to treat fever and malaria.
The leaves contain high levels of a type of antioxidant called oleuropein. Olives and olive oil contain this too, but at lower levels.
Generally, the greener the leaf (the less yellowish) the more oleuropein it contains. Leaves picked in spring also have higher levels compared to ones picked in autumn, indicating levels of oleuropein reduce as the leaves get older.
Olive leaves also contain other antioxidants such as hydroxytyrosol, luteolin, apigenin and verbascoside.
Antioxidants work by reducing the oxidative stress in the body. Oxidative stress causes damage to our DNA, cell membranes and tissues, which can lead to chronic diseases such as cancer and heart disease.
Are olive leaves healthy?
One review and analysis combined data from 12 experimental studies with 819 participants in total. Overall, olive leaf extract improved risk factors for heart disease. This included healthier blood lipids (fats) and lowering blood pressure.
The effect was greater for people who already had high blood pressure.
Most studies in this review gave olive leaf extract as a capsule, with daily doses of 500 milligrams to 5 grams for six to 48 weeks.
Another review and analysis published late last year looked at data from 12 experimental studies, with a total of 703 people. Some of these studies involved people with high blood lipids, people with high blood pressure, people who were overweight or obese, and some involved healthy people.
Daily doses were 250-1,000mg taken as tablets or baked into bread.
Individual studies in the review showed significant benefits in improving blood glucose (sugar) control, blood lipid levels and reducing blood pressure. But when all the data was combined, there were no significant health effects. We’ll explain why this may be the case shortly.
Olive leaves can be brewed into tea. Picture Partners/Shutterstock Another review looked at people who took oleuropein and hydroxytyrosol (the antioxidants in olive leaves). This found significant improvement in body weight, blood lipid profiles, glucose metabolism and improvements in bones, joints and cognitive function.
The individual studies included tested either the two antioxidants or olive leaf incorporated into foods such as bread and cooking oils (but not olive oil). The doses were 6-500mg per day of olive leaf extract.
So what can we make of these studies overall? They show olive leaf extract may help reduce blood pressure, improve blood lipids and help our bodies handle glucose.
But these studies show inconsistent results. This is likely due to differences in the way people took olive leaf extract, how much they took and how long for. This type of inconsistency normally tells us we need some more research to clarify the health effects of olive leaves.
Can you eat olive leaves?
Olive leaves can be brewed into a tea, or the leaves added to salads. Others report grinding olive leaves into smoothies.
However the leaves are bitter, because of the antioxidants, which can make them hard to eat, or the tea unpalatable.
Olive leaf extract has also been added to bread and other baked goods. Researchers find this improves the level of antioxidants in these products and people say the foods tasted better.
Olive leaves can taste bitter, which can put people off. But you can bake the extract into bread. Repina Valeriya/Shutterstock Is olive leaf extract toxic?
No, there seem to be no reported toxic effects of eating or drinking olive leaf extract.
It appears safe up to 1g a day, according to studies that have used olive leaf extract. However, there are no official guidelines about how much is safe to consume.
There have been reports of potential toxicity if taken over 85mg/kg of body weight per day. For an 80kg adult, this would mean 6.8g a day, well above the dose used in the studies mentioned in this article.
Pregnant and breastfeeding women are recommended not to consume it as we don’t know if it’s safe for them.
What should I do?
If you have high blood pressure, diabetes or raised blood lipids you may see some benefit from taking olive leaf extract. But it is important you discuss this with your doctor first and not change any medications or start taking olive leaf extract until you have spoken to them.
But there are plenty of antioxidants in all plant foods, and you should try to eat a wide variety of different coloured plant foods. This will allow you to get a range of nutrients and antioxidants.
Olive leaf and its extract is not going to be a panacea for your health if you’re not eating a healthy diet and following other health advice.

Vaginal Probiotics: What Does The Science Say?
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’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 😎
❝Is there any merit to vaginal probiotics?❞
What a fun question! First let’s break it down, as this could mean two different things:
- Probiotics, which you consume, using your mouth, which are marketed as benefiting vaginal health
- Probiotics taken as a vaginal pessary/suppository, to act directly there
The former has limited evidence for it, but generally speaking, improving one’s gut health improves all other areas of health, so it’s not surprising if it helps this too.
See for example:
Some notes:
- candidal vaginitis means a yeast infection causing vaginal inflammation
- bacterial vaginosis means a vaginal bacterial imbalance (generally also featuring vaginal inflammation, though it can be asymptomatic)
In the latter case, the “imbalance” in question is usually a shortage of Lactobacillus sp. (that is to say, the diverse species of the Lactobacillus genus) resulting in an overgrowth of other kinds of bacteria, which in turn results in changing the vaginal microbiome to make it warmer and more acidic than it should be.
While a healthy vagina shouldn’t smell of roses, it shouldn’t smell fishy either; if it does, that’s a sign of bacterial vaginosis.
What it’s supposed to be like: slightly bitter, slightly salty, distinctly umami, along with a cocktail of personal pheromones (and if menstruating or otherwise* vaginally bleeding, then of course add: iron/”metallic”). The pheromones will also reflect any hormonal changes, but should never make anything smell bad, just different.
*e.g. due to PCOS, fibroids, etc. Note that in the case of PCOS, it may also smell a little different (if it does, then usually: a little more musky), due to often different hormone levels. Again: it still shouldn’t smell bad, though, just different.
In the above-linked study, taking more live Lactobacillus acidophilus (in yogurt, eating it, with their mouths) improved levels of L. acidophilus in the vagina. While the study authors concluded “this ingestion of yogurt may have reduced episodes of bacterial vaginosis”, which is rather a weak claim, it can be argued that it merely improving the levels of L. acidophilus in the vagina was already a win.
That was a small (n=42, and only 7 followed through to completion) and old (1996) study, and it bears mentioning that most of the studies into this seem to be small and old, but conclude similarly with weakly positive statements.
However, it does make a difference what kind of Lactobacillus is used, for example in this next study…
- L. fermentum RC-14 worked well (90% success rate)
- L. rhamnosus GR-1 worked somewhat (40% success rate)
- L. rhamnosus GG did not work (0% success rate)
So, diversity is key, and getting a wide range of Lactobacillus sp. seems to be a safe bet.
Short version: enjoying probiotics as part of your diet probably improves vaginal health, just like it improves pretty much everything else.

You would think that this would mean that taking probiotics as a vaginal pessary/suppository would be even better, but the results are weaker, as in this study, which produced temporary improvements in about half the study group, with only 3 out of 28 being free of bacterial vaginosis the next month:
Treatment of bacterial vaginosis with lactobacilli
This study got better results, with a 61% success rate:
Important note
Do note that this last category, involving topical treatments (i.e., manually introducing Lactobacillus sp. to the vagina) were all in cases of pre-existing bacterial vaginosis, not as a prophylactic and/or general health-improving thing.
If your vagina seems happy right now, then do not mess with its happy bacterial balance!
And at all times (regardless of whether it seems happy right now or not): do not douche (it does not need it and will not benefit from it; the vagina is self-cleaning*) as this will wash out many of your Lactobacilli and will do absolutely nothing against any Candida there (C. albicans being a rooted fungus, whereas Lactobacillus is a sausage-shaped bacterium with many tiny appendages but no actual ability to stay put), so Candida will flourish in the Lactobacillus’s absence.
*by the vagina, we are referring to the vaginal canal. The vulva—the outside part consisting of the two pairs of labia, the glans clitoris, and clitoral hood—are not self-cleaning, and should just be washed gently per your normal bath/shower routine; that’s perfectly fine and good.
And definitely don’t put any “cleansing” toiletries inside the vagina (or any toiletries at all, for that matter), even if they are sold and marketed for that purpose; they will not help and they will harm.
Also, due to their neighborliness, messing up the microbiome inside the vagina is a common way to also get Candida inside the urethra:

One other option
Finally, unless you have a “very good friend” you have a pressing urge to swap germs with, you might want to leave this one to the scientists, but we share this paper just for interest:
Lastly…

Tips for Improving Memory
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.
Q&A with 10almonds Subscribers!
Q: Any tips, other than supplements, for improving memory?
A: So many tips! Certainly enough to do a main feature on, so again maybe we’ll do that in another issue soon. Meanwhile, here are the absolute most critical things for you to know, understand, and apply:
- Memory is a muscle. Not literally, but in the sense that it will grow stronger if exercised and will atrophy if neglected.
- Counterpart of the above: your memory is not a finite vessel. You can’t “fill it up with useless things”, so no need to fear doing so.
- Your memory is the product of countless connections in your brain. The more connections lead to a given memory, the more memorable it will be. What use is this knowledge to you? It means that if you want to remember something, try to make as many connections to it as possible, so:
- Involve as many senses as possible.
- When you learn things, try to learn them in context. Then when your mind has reason to think about the context, it’ll be more likely to remember the thing itself too.
- Rehearsal matters. A lot. This means repeatedly going over something in your head. This brings about the neural equivalent of “muscle memory”.
- Enjoy yourself if you can. The more fun something is, the more you will mentally rehearse it, and the more mental connections you’ll make to it.

You Are the One You’ve Been Waiting For – by Dr. Richard Schwartz
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.
As self-therapy approaches go, the title here could be read two ways: as pop-psychology fluff, or a suggestion of something deeper. And, while written in a way to make it accessible to all, we’re happy to report the content consists of serious therapeutic ideas, presented clearly.
Internal Family Systems (IFS) is a large, internationally recognized, and popular therapeutic approach. It’s also an approach that lends itself quite well to self-therapy, as this book illustrates.
Dr. Schwartz kicks off by explaining not IFS, but the problem that it solves… We (most of us, anyway) have over the course of our lives tried to plug the gaps in our own unmet psychological needs. And, that can cause resentment, strain, and can even be taken out on others if we’re not careful.
The real meat of the book, however, is in its illustrative explanations of how IFS works, and can be applied by an individual. The goal is to recognize all the parts that make us who we are, understand what they need in order to be at peace, and give them that. Spoiler: most what they will need is just being adequately heard, rather than locked in a box untended.
One of the benefits of using this book for self-therapy, of course, is that it requires a lot less vulnerability with a third party.
But, speaking of which, what of these intimate relationships the subtitle of the book referenced? Mostly the benefits to such come from a “put your own oxygen mask on first” angle… but the book does also cover discussions between intimate partners, and approaches to love, including what the author calls “courageous love”.
Bottom line: this is a great book if you want to do some “spring-cleaning of the soul” and live a little more lightly as a result.

Top Foods Against Neuroinflammation
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.
Chronic inflammation is something you might feel in your joints, but it will usually be in the brain too. There, neuroinflammation can disrupt brain function, affecting stress responses, mood, cognition, and even alter brain structure. It’s also heavily implicated in the pathogenesis of various forms of dementia.
What to do about it
Dr. Tracey Marks, psychiatrist, bids us eat:
- Fatty fish: omega-3-rich fish like salmon reduce neuroinflammation.
- Leafy greens: spinach, kale, and collards protect brain cells and support neurotransmitter production.
- Berries: blueberries and strawberries improve memory and protect neurons.
- Nuts and seeds: walnuts, almonds, and flaxseeds support brain health and reduce inflammation.
- Turmeric: curcumin combats inflammation and supports neuron growth (best with supplements).
- Fermented foods: yogurt and sauerkraut improve gut health, benefiting the brain via the gut-brain axis; not just the vagus nerve, but also, remember that various neurotransmitters (including serotonin) are made in the gut.
Of course, you should also avoid alcohol, nicotine, red meat, processed meat, and ideally also white flour products, and sugary foods (unless they are also rich in fiber, like whole fruit).

Ayurveda’s Contributions To Science
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.
Ayurveda’s Contributions To Science (Without Being Itself Rooted in Scientific Method)
Yesterday, we asked you for your opinions on ayurveda, and got the above-depicted, below-described, set of responses. Of those who responded…
- A little over 41% said “I don’t know what ayurveda is without looking it up”
- A little over 37% said “It is a fine branch of health science with millennia of evidence”
- A little over 16% said “It gets some things right, but not by actual science”
- A little over 4% said “It is a potentially dangerous pseudoscience”
So, what does the science say?
Ayurveda is scientific: True or False?
False, simply. Let’s just rip the band-aid off in this case. That doesn’t mean it’s necessarily without merit, though!
Let’s put it this way:
- If you drink coffee to feel more awake because scientific method has discerned that caffeine has vasoconstrictive and adenosine-blocking effects while also promoting dopaminergic activity, then your consumption of coffee is evidence-based and scientific. Great!
- If you drink coffee to feel more awake because somebody told you that that somebody told them that it energizes you by balancing the elements fire (the heat of the coffee), air (the little bubbles on top), earth (the coffee grinds), water (the water), and ether (steam), then that is neither evidence-based nor scientific, but it will still work exactly the same.
Ayurveda is a little like that. It’s an ancient traditional Indian medicine, based on a combination of anecdotal evidence and supposition.
- The anecdotal evidence from ayurveda has often resulted in herbal remedies that, in modern scientific trials, have been found to have merit.
- Ayurvedic meditative practices also have a large overlap with modern mindfulness practices, and have also been found to have merit
- Ayurveda also promotes the practice of yoga, which is indeed a very healthful activity
- The supposition from ayurveda is based largely in those five elements we mentioned above, as well as a “balancing of humors” comparable to medieval European medicine, and from a scientific perspective, is simply a hypothesis with no evidence to support it.
Note: while ayurveda is commonly described as a science by its practitioners in the modern age, it did not originally claim to be scientific, but rather, wisdom handed down directly by the god Dhanvantari.
Ayurveda gets some things right: True or False?
True! Indeed, we covered some before in 10almonds; you may remember:
Bacopa Monnieri: A Well-Evidenced Cognitive Enhancer
(Bacopa monnieri is also known by its name in ayurveda, brahmi)
There are many other herbs that have made their way from ayurveda into modern science, but the above is a stand-out example. Others include:
- Ashwagandha: The Root of All Even-Mindedness?
- Boswellia serrata (Frankincense) Against Pain and Depression/Anxiety
Yoga and meditation are also great, and not only that, but great by science, for example:
- NCCIH | Yoga for Health: Clinical Guidelines, Scientific Literature, Info for Patients
- The Neuroscience of Mindfulness: How Mindfulness Alters the Brain and Facilitates Emotion Regulation
Ayurveda is a potentially dangerous pseudoscience: True or False?
Also True! We covered why it’s a pseudoscience above, but that doesn’t make it potentially dangerous, per se (you’ll remember our coffee example).
What does, however, make it potentially dangerous (dose-dependent) is its use of heavy metals such as lead, mercury, and arsenic:
Heavy Metal Content of Ayurvedic Herbal Medicine Products
Some final thoughts…
Want to learn more about the sometimes beneficial, sometimes uneasy relationship between ayurveda and modern science?
A lot of scholarly articles trying to bridge (or further separate) the two were very biased one way or the other.
Instead, here’s one that’s reasonably optimistic with regard to ayurveda’s potential for good, while being realistic about how it currently stands:
