The Vagina Bible – by Dr. Jen Gunter

The vagina is mysterious to most men, and honestly, also to a lot of women. School education on this is minimal, if even extant, and as an adult, everyone’s expected to “just know” stuff. However, here in reality, that isn’t how knowledge works.
To remedy this, gynecologist Dr. Jen Gunter takes 432 pages to give us the low-down and the ins-and-outs of this remarkable organ that affects, and is affected by, a lot of the rest of our health.
(On which note, if you think you already know it, ask yourself: could you write 432 pages about it? If not, you’ll probably still learn some things from this book)
Stylistically, this book is more of a textbook in presentation, but the writing is still very much easy-reading. The focus is mostly on anatomy and physiology, though she does give due attention to relevant healthcare options; what’s good, what’s bad, and what’s just plain unnecessary. In such cases, she always has plenty of science to hand; it’s never just “one woman’s opinion”.
If the book has a downside, it’s that (based on other reviews) it seems to upset some readers with unwelcome truths, but that’s more in the vein of “she’s right, of course, but I didn’t like reading it”.
Bottom line: if you have a vagina, or spend any amount of time in close proximity to one, then this is a great book for you.

3 Things Everyone Over 50 Must Do Daily for Healthy Feet
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.
Will Harlow, the over-50s specialist physio, wants you to be on a good footing:
Daily steps in the right direction
The three daily exercises recommended in the video are:
Exercise 1: Towel Scrunch
The towel scrunch exercise strengthens the flexor muscles in the feet, improving balance and improving contact with the ground. To do this exercise, sit on a chair with a towel placed on the floor beneath your toes while keeping your heels on the ground. Use only your toes to pull the towel toward your heel, scrunching it up as much as possible. This movement strengthens the arch of the foot and can help alleviate symptoms of flat feet. For best results, practice this exercise for 2–3 minutes once or twice daily. Once you’ve got the hand of doing it sitting, do it while standing.
Exercise 2: Big Toe Extension
Big toe extension is an essential exercise for maintaining foot mobility and improving walking kinesthetics by preventing stiffness in the big toe. To do this exercise, keep your foot flat on the floor and try to lift only your big toe while keeping the four other toes firmly pressed down. To be clear, we mean under its own power; not using your hands to help. Many people find this difficult initially, but it’s due to a loss of neural connection rather than muscle strength, so with practice, the ability to isolate the movement improves quite quickly. Perform 10 repetitions in a row, three times per day, for optimal benefits. Once you’ve got the hand of doing it sitting, do it while standing.
Exercise 3: Calf Stretch
The calf stretch is an important exercise for maintaining foot health by preventing tight calves, which can contribute to issues like plantar fasciitis and Morton’s neuroma. To do this stretch, place your hands against a wall for support and extend one leg straight behind you while keeping your other heel firmly on the floor. The front knee should be bent while the back leg remains straight, creating a stretch in the calf. Hold this position for 30 seconds (building up to that, if necessary). Since the effectiveness of stretching comes from frequency rather than duration, this stretch should be performed three to four times per day for the best results.
For more on each of these, plus visual demonstrations, enjoy:

Avocado vs Jackfruit – 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 avocado to jackfruit, we picked the avocado.
Why?
In terms of macros, avocado is higher in fats (famously healthy ones, including a good dose of omega-3), fiber (nearly 5x more), and protein (despite jackfruit being more often used as a meaty element in recipes, avocado has slightly more). Meanwhile, jackfruit is about 3x higher in carbs. All in all, a clear win for avocado.
Looking at vitamins, avocado has more of vitamins A, B2, B3, B5, B7, B9, E, K, and choline, while jackfruit has more of vitamins B1, B6, and C. Another win for avocado in this category.
In the category of minerals, avocado has more copper, iron, manganese, phosphorus, potassium, selenium, and zinc, while jackfruit has more calcium. One more win for avocado.
Adding up the sections makes for an easy overall win for avocado, but by all means enjoy either or both; diversity is good!

No, vitamin A does not prevent measles
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 measles spreads in Texas, New Mexico, and other states, a Texas child died from measles for the first time in the United States since 2015. In a March 2 Fox News editorial, Health and Human Services Secretary Robert F. Kennedy Jr. hinted at the importance of vaccination and stated that good nutrition, including vitamin A, is a “best defense against most chronic and infectious illnesses.”
However, doctors and public health professionals say that vitamin A is not a replacement for the measles, mumps, and rubella (MMR) vaccine. Vitamin A is sometimes used to treat measles in the hospital—particularly in developing countries where people with poor nutrition tend to be vitamin A deficient. Experts also say that taking vitamin A when your body does not need it can be dangerous.
“It’s really important to distinguish prevention and treatment, and measles can be prevented, and it can be prevented one way: through vaccination,” Dr. Preeti Malani, infectious disease physician and professor at the University of Michigan, tells PGN. “The best treatment is to not get measles in the first place.”
Read on to learn the facts about vitamin A, what it’s used for, its risks, and what you should do to prevent measles.
What is vitamin A, and what does it have to do with measles?
Vitamin A is a fat-soluble vitamin, which means that it’s stored in the body’s fatty tissue and in the liver, and it’s absorbed with the fat in a person’s diet. Vitamin A helps with our vision, reproduction, growth, and immunity.
Vitamin A deficiency can increase the risk of death from measles, among other infections. The World Health Organization recommends it as a supplement along with vaccination for children at risk of vitamin A deficiency in developing countries.
However, vitamin A deficiency is rare in the U.S. because most people get enough of it through their diet. (Malani says that’s why research about the use of vitamin A to treat measles is limited in countries like the United States.)
“Vitamin A deficiency is a major problem in developing nations, particularly those that don’t have access to staple foods that have vitamin A,” says Andrea Love, PhD, a biomedical scientist and founder of the health communication organization Immunologic, to PGN. “The problem is that that’s been kind of extrapolated to high-income countries [like the United States], where vitamin A deficiency is really not a concern.”
Under Kennedy’s direction, the Centers for Disease Control and Prevention recently updated its guidance to recommend the use of vitamin A to treat severe measles in young children, but specifically in a hospital setting and under a doctor’s supervision.
Does vitamin A prevent measles?
No. Vitamin A does not prevent measles. The MMR vaccine is the best way to prevent a measles infection.
“Vitamin A is not an alternative to vaccination,” Malani adds. “We have a safe and highly effective vaccine that’s been available for decades—it will protect individuals [and] communities from an outbreak.”
Are there any risks to taking vitamin A?
Yes. If your body doesn’t need extra vitamin A, there are risks.
According to the National Institutes of Health, taking too much vitamin A (specifically, the type found in supplements and some medications) can cause nausea, severe headaches, blurred vision, muscle aches, and problems with coordination. In severe cases, it can also lead to coma and death. Taking too much vitamin A while pregnant can cause birth defects.
“If you’re already getting sufficient vitamin A from your diet, then when you consume more than what you need, those levels are going to build up in your body, in your fat stores, in your tissues, and you’re going to be at risk of both acute and chronic toxicity,” adds Love.
Water-soluble vitamins like vitamin C “get filtered out by your kidneys and you would pee it out, but fat-soluble vitamins [like vitamin A], don’t get processed and excreted as quickly; they start to build up in the body,” she says.
What can I do to protect myself from measles?
The MMR vaccine is the best way to protect yourself from measles. The CDC recommends children get two doses of the MMR vaccine: the first dose between 12 and 15 months and the second one between 4 and 6 years old.
Experts recommend that adults who are not sure about their vaccination or immunity status against measles get at least one dose of the MMR vaccine. Additionally, adults who are at high risk for measles (like health care workers and people who travel internationally) may need two additional doses.
According to the CDC, you can also get an MMR vaccine within 72 hours of initial exposure to measles, which can give you some protection or make your illness less severe. Additionally, there’s an antibody (a protective protein called immunoglobulin) that a doctor may recommend for high-risk people within six days of being exposed to measles.

Blue Light At Night? Save More Than Just Your Sleep!
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.
Beating The Insomnia Blues
You previously asked us about recipes for insomnia (or rather, recipes/foods to help with easing insomnia). We delivered!
But we also semi-promised we’d cover a bit more of the general management of insomnia, because while diet’s important, it’s not everything.
Sleep Hygiene
Alright, you probably know this first bit, but we’d be remiss if we didn’t cover it before moving on:
- No caffeine or alcohol before bed
- Ideally: none earlier either, but if you enjoy one or the other or both, we realize an article about sleep hygiene isn’t going to be what changes your mind
- Fresh bedding
- At the very least, fresh pillowcase(s). While washing and drying an entire bedding set constantly may be arduous and wasteful of resources, it never hurts to throw your latest pillowcase(s) in with each load of laundry you happen to do.
- Warm bed, cool room = maximum coziness
- Dark room. Speaking of which…
About That Darkness…
When we say the room should be dark, we really mean it:
- Not dark like “evening mood lighting”, but actually dark.
- Not dark like “in the pale moonlight”, but actually dark.
- Not dark like “apart from the light peeking under the doorway”, but actually dark.
- Not dark like “apart from a few LEDs on electronic devices that are on standby or are charging”, but actually dark.
There are many studies about the impact of blue light on sleep, but here’s one as an example.
If blue light with wavelength between 415 nm and 455 nm (in the visible spectrum) hits the retina, melatonin (the sleep hormone) will be suppressed.
The extent of the suppression is proportional to the amount of blue light. This means that there is a difference between starting at an “artificial daylight” lamp, and having the blue LED of your phone charger showing… but the effect is cumulative.
And it gets worse:
❝This high energy blue light passes through the cornea and lens to the retina causing diseases such as dry eye, cataract, age-related macular degeneration, even stimulating the brain, inhibiting melatonin secretion, and enhancing adrenocortical hormone production, which will destroy the hormonal balance and directly affect sleep quality.❞
Read it in full: Research progress about the effect and prevention of blue light on eyes
See also: Age-related maculopathy and the impact of blue light hazard
So, what this means, if we value our health, is:
- Switch off, or if that’s impractical, cover the lights of electronic devices. This might be as simple as placing your phone face-down rather than face-up, for instance.
- Invest in blackout blinds/curtains (per your preference). Serious ones, like these ← see how they don’t have to be black to be blackout! You don’t have to sacrifice style for function
- If you can’t reasonably do the above, consider a sleep mask. Again, a good one. Not the kind you were given on a flight, or got free with some fluffy handcuffs. We mean a full-blackout sleep mask that’s designed to be comfortable enough to sleep in, like this one.
- If you need to get up to pee or whatever, do like a pirate and keep one eye covered/closed. That way, it’ll remain unaffected by the light. Pirates did it to retain their night vision when switching between being on-deck or below, but you can do it to halve the loss of melatonin.
Lights-Out For Your Brain Too
You can have all the darkness in the world and still not sleep if your mind is racing thinking about:
- your recent day
- your next day
- that conversation you wish had gone differently
- what you really should have done when you were 18
- how you would go about fixing your country’s socio-political and economic woes if you were in charge
- Etc.
We wrote about how to hit pause on all that, in a previous edition of 10almonds.

Brussels Sprouts vs Broccoli – 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 sprouts to broccoli, we picked the sprouts.
Why?
First let’s note that we have an interesting comparison today, because these two plants are the exact same species (and indeed, also the exact same species as cabbage, cauliflower. and kale)—just a different cultivar. All of these plants and more are simply cultivars of Brassica oleracea.
Them being the same species notwithstanding, there are nutritional differences:
In terms of macros, sprouts have slightly more protein, carbohydrates, and fiber, whereas broccoli has slightly more water weight. An easy win for sprouts here.
In the category of vitamins, sprouts have more of vitamins A, B1, B3, B6, C, E, and K, while broccoli has more of vitamins B2 and B5. Another easy win for sprouts.
When it comes to minerals, sprouts again lead with more copper, iron, magnesium, manganese, phosphorus, and potassium, while broccoli has more calcium and selenium.
A note on oxalates: while oxalates are not a problem for most people, it is important to be mindful of them if one has kidney problems. You may know that spinach (a fellow green vegetable high in vitamins and minerals, as well as being a fellow oleracea, albeit of a different genus, so not the same species for once) is high in oxalates, but these two Brassica oleracea we compared today are amongst the lowest in oxalates (source 1 | source 2), making them an ideal way to get vitamins, minerals, and fiber on an oxalate-controlled diet.
Since both are also high in polyphenols, especially kaempferol and quercetin, we’ll mention that sprouts have more lignans while broccoli has more flavonoids. In short: they’re both very good, just different.
As ever, enjoy both! But if you’re going to pick one for total best nutritional density, it’s sprouts.

Get Better Sleep: Beyond The Basics
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.
First though, for the sake of being methodical, let’s quickly note the basics:
- Aim for 7–9 hours per night
- Set a regular bedtime and (equally important!) regular getting-up time
- Have a 2-hour wind-down period before bed, to decompress from any stresses of the day
- Minimal device/screen usage before bed
- Abstain from stimulants for as long before bed as reasonably possible (caffeine elimination halflife is 4–8 hours depending on your genes, call it 6 hours average to eliminate half (not the whole lot), and you’ll see it’s probably best to put a cap on it earlier rather than later).
- Abstain from alcohol, ideally entirely, but allow at least 1hr/unit before bed. So for example, 1hr for a 1oz single shot of spirits, or 2–3 hours for a glass of wine (depending on size), or 3–4 hours for a martini (depending on recipe). Not that that is not the elimination time, nor even the elimination halflife of alcohol, it’s just a “give your body a chance at least” calculation. If you like to have a drink to relax before bed, then well, only you can decide what you like more: that or actually getting restorative sleep.
- Consider a warm bath/shower before bed, if that suits your schedule.
- Wash and change your bedsheets more often than seems necessary. Or if that’s too onerous, at least change the pillowcases more often, which makes quite a difference already.
- Lower the temperature of your bedroom shortly before bedtime; this will help cue the body to produce melatonin
- Make your bedroom as dark as reasonably possible. Invest in blackout blinds/curtains, and remove any pesky electronics, or at least cover their little LEDs if it’s something that reasonably needs to remain on.
Ok, now, onwards…
Those 7–9 hours? Yes, it goes for you too.
A lot of people mistake getting 6 hours sleep per night for only needing 6 hours sleep per night. Sure, you may still be alive after regularly getting 6 hours, but (unless you have a rare mutation of the ADRB1 gene) it will be causing harm, and yes, that includes later in life; we don’t stop needing so much sleep, even stop getting it:
Why You Probably Need More Sleep
With this in mind, it becomes important to…
Prioritize your sleep—which means planning for it!
When does your bedtime routine start? According to sleep scientist Dr. Lisa Matricciani, it starts before breakfast. This is because the things we do earlier in the day can greatly affect the amount (and quality) of sleep we get later. For example, a morning moderate-to-intense exercise session greatly improves sleep at night:
Planning Ahead For Better Sleep
As for quality, that is as important as quantity, and it’s not just about “soundness” of sleep:
The 6 Dimensions Of Sleep (And Why They Matter)
“What gets measured, gets done” goes for sleep too
Sleep-deprived people usually underestimate how sleep-deprived they are. This is for the same reason as why drunk people usually underestimate how drunk they are—to put it in words that go for both situations: a cognitively impaired person lacks the cognitive function to realize how cognitively impaired they are.
Here’s the science on that, by the way:
How Sleep-Deprived Are You, Really?
For that reason, we recommend using sleep-tracking software (there are many apps for that) on your phone or, ideally, a wearable device (such as a smartwatch or similar).
A benefit of doing so is that we don’t think “well, I slept from 10pm to 6am, so that’s 8 hours”, if our device tells us we slept between 10:43pm and 5:56 am with 74% sleep efficiency because we woke up many times.
As an aside, sleep efficiency should be about 85%, by the way. Why not 100%, you ask? It’s because if your body is truly out like a light for the entire night, something is wrong (either you were very sleep-deprived, or you have been drugged, that kind of thing). See also:
An unbroken night’s sleep is a myth. Here’s what good sleep looks like.
So waking up during the night is normal, and nothing to worry about per se. If you do find trouble getting back to sleep, though:

Be careful about how you try to supplement sleep
This goes both for taking substances of various kinds, and napping. Some sleep aids can help, but many are harmful and/or do not really work as such; here’s a rundown of examples of those:
