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:

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:

Kale vs Watercress – 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 kale to watercress, we picked the kale.
Why?
It was very close! If ever we’ve been tempted to call something a tie, this has been the closest so far.
Their macros are close; watercress has a tiny amount more protein and slightly lower carbs, but these numbers are tiny, so it’s not really a factor. Nevertheless, on macros alone we’d call this a slight nominal win for watercress.
In terms of vitamins, they’re even. Watercress has higher vitamin E and choline (sometimes considered a vitamin), as well as being higher in some B vitamins. Kale has higher vitamins A and K, as well as being higher in some other B vitamins.
In the category of minerals, watercress has higher calcium, magnesium, phosphorus, and potassium, while kale has higher copper, iron, manganese, and zinc. The margins are slightly wider for kale’s more plentiful minerals though, so we’ll call this section a marginal win for kale.
When it comes to polyphenols, kale takes and maintains the lead here, with around 2x the quercetin and 27x the kaempferol. Watercress does have some lignans that kale doesn’t, but ultimately, kale’s strong flavonoid content keeps it in the lead.
So of course: enjoy both if both are available! But if we must pick one, it’s kale.

How To Stay Alive (When You Really Don’t Want To)

How To Stay Alive (When You Really Don’t Want To)
A subscriber recently requested:
❝Request: more people need to be aware of suicidal tendencies and what they can do to ward them off❞
…and we said we’d do that one of these Psychology Sundays, so here we are, doing it!
First of all, we’ll mention that we did previously do a main feature on managing depression (in oneself or a loved one); here it is:
The Mental Health First Aid That You’ll Hopefully Never Need
Now, not all depression leads to suicidality, and not all suicide is pre-empted by depression, but there’s a large enough crossover that it seems sensible to put that article here, for anyone who might find it of use, or even just of interest.
Now, onwards, to the specific, and very important, topic of suicide.
This should go without saying, but some of today’s content may be a little heavy.
We invite you to read it anyway if you’re able, because it’s important stuff that we all should know, and not talking about it is part of what allows it to kill people.
So, let’s take a deep breath, and read on…
The risk factors
Top risk factors for suicide include:
- Not talking about it
- Having access to a firearm
- Having a plan of specifically how to commit suicide
- A lack of social support
- Being male
- Being over 40
Now, some of these are interesting sociologically, but aren’t very useful practically; what a convenient world it’d be if we could all simply choose to be under 40, for instance.
Some serve as alarm bells, such as “having a plan of specifically how to commit suicide”.
If someone has a plan, that plan’s never going to disappear entirely, even if it’s set aside!
(this writer is deeply aware of the specifics of how she has wanted to end things before, and has used the advice she gives in this article herself numerous times. So far so good, still alive to write about it!)
Specific advices, therefore, include:
Talk about it / Listen
Depending on whether it’s you or someone else at risk:
- Talk about it, if it’s you
- Listen attentively, if it’s someone else
There are two main objections that you might have at this point, so let’s look at those:
“I have nobody to talk to”—it can certainly feel that way, sometimes, but you may be surprised who would listen if you gave them the chance. If you really can’t trust anyone around you, there are of course suicide hotlines (usually per area, so we’ll not try to list them here; a quick Internet search will get you what you need).
If you’re worried it’ll result in bad legal/social consequences, check their confidentiality policy first:
- Some hotlines can and will call the police, for instance.
- Others deliberately have a set-up whereby they couldn’t even trace the call if they wanted to.
- On the one hand, that means they can’t intervene
- On the other hand, that means they’re a resource for anyone who will only trust a listener who can’t intervene.
“But it is just a cry for help”—then that person deserves help. What some may call “attention-seeking” is, in effect, care-seeking. Listen, without judgement.
Remove access to firearms, if applicable and possible
Ideally, get rid of them (safely and responsibly, please).
If you can’t bring yourself to do that, make them as inconvenient to get at as possible. Stored securely at your local gun club is better than at home, for example.
If your/their plan isn’t firearm-related, but the thing in question can be similarly removed, remove it. You/they do not need that stockpile of pills, for instance.
And of course you/they could get more, but the point is to make it less frictionless. The more necessary stopping points between thinking “I should just kill myself” and being able to actually do it, the better.
Have/give social support
What do the following people have in common?
- A bullied teenager
- A divorced 40-something who just lost a job
- A lonely 70-something with no surviving family, and friends that are hard to visit
Often, at least, the answer is: the absence of a good social support network
So, it’s good to get one, and be part of some sort of community that’s meaningful to us. That could look different to a lot of people, for example:
- A church, or other religious community, if we be religious
- The LGBT+ community, or even just a part of it, if that fits for us
- Any mutual-support oriented, we-have-this-shared-experience community, could be anything from AA to the VA.
Some bonus ideas…
If you can’t live for love, living for spite might suffice. Outlive your enemies; don’t give them the satisfaction.
If you’re going to do it anyway, you might as well take the time to do some “bucket list” items first. After all, what do you have to lose? Feel free to add further bucket list items as they occur to you, of course. Because, why not? Before you know it, you’ve postponed your way into a rich and fulfilling life.
Finally, some gems from Matt Haig’s “The Comfort Book”:
- “The hardest question I have been asked is: “How do I stay alive for other people if I have no one?” The answer is that you stay alive for other versions of you. For the people you will meet, yes, but also the people you will be.”
- “Stay for the person you will become”
- “You are more than a bad day, or week, or month, or year, or even decade”
- “It is better to let people down than to blow yourself up”
- “Nothing is stronger than a small hope that doesn’t give up”
- “You are here. And that is enough.”
You can find Matt Haig’s excellent “The Comfort Book” on Amazon, as well as his more well-known book more specifically on the topic we’ve covered today, “Reasons To Stay Alive“.

The How Not to Die Cookbook – by Dr. Michael Greger
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 previously reviewed Dr. Greger’s “How Not To Die”, which is excellent and/but very science-dense.
This book is different, in that the science is referenced and explained throughout, but the focus is the recipes, and how to prepare delicious healthy food in accordance with the principles laid out in How Not To Die.
It also follows “Dr Greger’s Daily Dozen“, that is to say, the 12 specific things he advises we make sure to have every day, and thus helps us to include them in an easy, no-fuss fashion.
The recipes themselves are by Robin Robertson, and/but with plenty of notes by Dr Greger; they clearly collaborated closely in creating them.
The ingredients are all things one can find in any well-stocked supermarket, so unless you live in a food desert, you can make these things easily.
And yes, the foods are delicious too.
Bottom line: if you’re interested in cooking according to perhaps the most science-based dietary system out there, then this book is a top-tier choice.

3 Appetite Suppressants Better Than Ozempic

Dr. Annette Bosworth gives her recommendations, and explains why:
What and how
We’ll get straight to it; the recommendations are:
- Coffee, black, unsweetened: not only suppresses the appetite but also boosts the metabolism, increasing fat burn.
- Salt: especially for when fasting (as under such circumstances we may lose salts without replenishing them), a small taste of this can help satisfy taste buds while replenishing sodium and—depending on the salt—other minerals. For example, if you buy “low-sodium salt” in the supermarket, this is generally sodium chloride cut with potassium chloride and/or occasionally magnesium sulfate.
- Ketones (MCT oil): ketones can suppress hunger, particularly when fasting causes blood sugar levels to drop. Supplementing with MCT oil promotes ketone production in the liver, training the body to produce more ketones naturally, thus curbing appetite.

ADHD 2.0 – by Dr. Edward Hallowell & Dr. John Ratey
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.
A lot of ADHD literature is based on the assumption that the reader is a 30-something parent of a child with ADHD. This book, on the other hand, addresses all ages, and includes just as readily the likelihood that the person with ADHD is the reader, and/or the reader’s partner.
The authors cover such topics as:
- ADHD mythbusting, before moving on to…
- The problems of ADHD, and the benefits that those exact same traits can bring too
- How to leverage those traits to get fewer of the problems and more of the benefits
- The role of diet beyond the obvious, including supplementation
- The role of specific exercises (especially HIIT, and balance exercises) in benefiting the ADHD brain
- The role of medications—and arguments for and gainst such
The writing style is… Thematic, let’s say. The authors have ADHD and it shows. So, expect comprehensive deep-dives from whenever their hyperfocus mode kicked in, and expect no stones left unturned. That said, it is very readable, and well-indexed too, for ease of finding specific sub-topics.
Bottom line: if you are already very familiar with ADHD, you may not learn much, and might reasonably skip this one. However, if you’re new to the topic, this book is a great—and practical—primer.

Better Sex Through Mindfulness – by Dr. Lori Brotto
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.
Female sexuality is such a taboo topic that, if one searches for (ob/gyn professor, women’s health research director, and psychologist) Dr. Brotto’s book on Google or Amazon, it suggests only “lori brotto mindfulness book”. So, for those brave enough to read a book that would have shocked Victorians, what does this one contain?
The focus is on, as the title suggests, better sex, by and for women. That said, it’s mostly because typically women are more likely to experience the problems described in the book; it’s nothing actually intrinsic to womanhood. A man with the same problems could read this book and benefit just the same.
While the book covers many possible problems between the sheets, the overarching theme is problems of the mind, such as:
- Not getting into the mood in the first place
- Losing the mood quickly and easily, such as by becoming distracted
- Difficulty achieving orgasm even when mechanically everything’s delightful
- Physical discomfort creating a barrier to enjoyment
…and yes, that last one is in part mind-stuff too! Though Dr. Brotto isn’t arguing that mindfulness is a panacea, just an incredibly useful tool. And, it’s one she not only explains very well, but also explains from the position of a wealth of scientific evidence… Enough so, that we see a one-star Amazon reviewer from Canada complained that it was too well-referenced! For us, though, it’s what we like to see.
Good science, presented clearly and usefully, giving practical tips that improve people’s lives.
Bottom line: if you’ve ever lost the mood because you got distracted into thinking about taxes or that meeting on Tuesday, this is the book for you.
