Toothpastes and mouthwashes: which kinds help, and which kinds harm?
You almost certainly brush your teeth. You might use mouthwash. A lot of people floss for three weeks at a time, often in January.
There are a lot of options for oral hygiene; variations of the above, and many alternatives too. This is a big topic, so rather than try to squeeze it all in one, this will be a several-part series.
For today, let’s look at toothpastes and mouthwashes, to start!
Toothpaste options
Toothpastes may contain one, some, or all of the following, so here are some notes on those:
Fluoride
Most toothpastes contain fluoride; this is generally recognized as safe though is not without its controversies. The fluoride content is the reason it’s recommended not to swallow toothpaste, though.
The fluoride in toothpaste can cause some small problems if overused; if you see unusually white patches on your teeth (your teeth are supposed to be ivory-colored, not truly white), that is probably a case of localized overcalcification because of the fluoride, and yes, you can have too much of a good thing.
Overall, the benefits are considered to far outweigh the risks, though.
Baking soda
Whether by itself or as part of a toothpaste, baking soda is a safe and effective choice, not just for cosmetic purposes, but for boosting genuine oral hygiene too:
- Enhanced plaque removal to improve gingival health: 3-month randomized clinical study of the effects of baking soda toothpaste on plaque and gingivitis
- The effects of two baking-soda toothpastes in enhancing mechanical plaque removal and improving gingival health: A 6-month randomized clinical study
- The efficacy of baking soda dentifrice in controlling plaque and gingivitis: A systematic review
Activated charcoal
Activated charcoal is great at removing many chemicals from things it touches. That includes the kind you might see on your teeth in the form of stains.
A topical aside on safety: activated charcoal is a common ingredient in a lot of black-colored Halloween-themed foods and drinks around this time of year. Beware, if you ingest these, there’s a good chance of it also cleaning out any meds you are taking. Ask your pharmacist about your own personal meds, but meds that (ingested) activated charcoal will usually remove include:
- Oral HRT / contraceptives
- Antidepressants (many kinds)
- Heart medications (at least several major kinds)
Toothpaste, assuming you are spitting-not-swallowing, won’t remove your medications though. Nor, in case you were worrying, will it strip tooth enamel, even if you have extant tooth enamel erosion:

However, it’s of no special extra help when it comes to oral hygiene itself, just removing stains.
So, if you’d like to use it for cosmetic reasons, go right ahead. If not, no need.
Hydrogen peroxide
This is generally not a good idea, speaking for the health. For whitening, yes, it works. But for health, not so much:
To be clear, when they say “alter”, they mean “in a bad way”. It increases inflammation and tissue damage.
If buying commercially-available whitening toothpaste made with hydrogen peroxide, the academic answer is that it’s a lottery, because brands’ proprietorial compounding processes vary widely and constantly with little oversight and even less transparency:
Is whitening toothpaste safe for dental health?: RDA-PE method
Mouthwash options
In the case of fluoride and hydrogen peroxide, the same advice (for and against) goes as per toothpaste.
Alcohol
There has been some concern about the potential carcinogenic effect of alcohol-based mouthwashes. According to the best current science, this one’s not an easy yes-or-no, but rather:
- If there are no other cancer risk factors, it does not seem to increase cancer risk
- If there are other cancer risk factors, it does make the risk worse

Non-Alcohol
Non-alcoholic mouthwashes are not without their concerns either. In this case, the potential problem is changing the oral microbiome (we are supposed to have one!), and specifically, that the spread of what it kills and what it doesn’t may result in an imbalance that causes a lowering of the pH of the mouth.
Put differently: it makes your saliva more acidic.
Needless to say, that can cause its own problems for teeth. The research on this is still emerging, with regard to whether the benefits outweigh the problems, but the fact that it has this effect seems to be a consensus. Here’s an example paper; there are others:
Effects of Chlorhexidine mouthwash on the oral microbiome
Flossing, scraping, and alternatives
These are important (and varied, and interesting) enough to merit their own main feature, rather than squeezing them in at the end.
So, watch this space for a main feature on these soon!

Okra vs Asparagus – 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 okra to asparagus, we picked the okra.
Why?
Both are great! But…
In terms of macros, okra has more fiber and carbs, making it the more nutrient dense option, for a similar glycemic index.
In the category of vitamins, okra has more of vitamins B1, B3, B6, B9, and C, while asparagus has more of vitamins B2, B5, E, K, and choline, making for a 5:5 tie, with similar margins of difference too. Thus, definitely a tie on vitamins.
When it comes to minerals, okra has more calcium, magnesium, manganese, phosphorus, potassium, and zinc, while asparagus has more copper, iron, and selenium. An easy 6:3 win for okra.
Both of these on-the-cusp-of-being-pungent vegetables have beneficial antioxidant polyphenols (especially various forms of quercetin), but okra has more.
Adding up the sections makes for an overall win for okra, but by all means enjoy either both; diversity is good!

Cost of living: if you can’t afford as much fresh produce, are canned veggies or frozen fruit just as good?
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.
The cost of living crisis is affecting how we spend our money. For many people, this means tightening the budget on the weekly supermarket shop.
One victim may be fresh fruit and vegetables. Data from the Australian Bureau of Statistics (ABS) suggests Australians were consuming fewer fruit and vegetables in 2022–23 than the year before.
The cost of living is likely compounding a problem that exists already – on the whole, Australians don’t eat enough fruit and vegetables. Australian dietary guidelines recommend people aged nine and older should consume two serves of fruit and five serves of vegetables each day for optimal health. But in 2022 the ABS reported only 4% of Australians met the recommendations for both fruit and vegetable consumption.
Fruit and vegetables are crucial for a healthy, balanced diet, providing a range of vitamins and minerals as well as fibre.
If you can’t afford as much fresh produce at the moment, there are other ways to ensure you still get the benefits of these food groups. You might even be able to increase your intake of fruit and vegetables.
New Africa/Shutterstock Frozen
Fresh produce is often touted as being the most nutritious (think of the old adage “fresh is best”). But this is not necessarily true.
Nutrients can decline in transit from the paddock to your kitchen, and while the produce is stored in your fridge. Frozen vegetables may actually be higher in some nutrients such as vitamin C and E as they are snap frozen very close to the time of harvest. Variations in transport and storage can affect this slightly.
Minerals such as calcium, iron and magnesium stay at similar levels in frozen produce compared to fresh.
Another advantage to frozen vegetables and fruit is the potential to reduce food waste, as you can use only what you need at the time.
Freezing preserves the nutritional quality of vegetables and increases their shelf life. Tohid Hashemkhani/Pexels As well as buying frozen fruit and vegetables from the supermarket, you can freeze produce yourself at home if you have an oversupply from the garden, or when produce may be cheaper.
A quick blanching prior to freezing can improve the safety and quality of the produce. This is when food is briefly submerged in boiling water or steamed for a short time.
Frozen vegetables won’t be suitable for salads but can be eaten roasted or steamed and used for soups, stews, casseroles, curries, pies and quiches. Frozen fruits can be added to breakfast dishes (with cereal or youghurt) or used in cooking for fruit pies and cakes, for example.
Canned
Canned vegetables and fruit similarly often offer a cheaper alternative to fresh produce. They’re also very convenient to have on hand. The canning process is the preservation technique, so there’s no need to add any additional preservatives, including salt.
Due to the cooking process, levels of heat-sensitive nutrients such as vitamin C will decline a little compared to fresh produce. When you’re using canned vegetables in a hot dish, you can add them later in the cooking process to reduce the amount of nutrient loss.
To minimise waste, you can freeze the portion you don’t need.
Fermented
Fermented vegetables are another good option. Angela Khebou/Unsplash Fermentation has recently come into fashion, but it’s actually one of the oldest food processing and preservation techniques.
Fermentation largely retains the vitamins and minerals in fresh vegetables. But fermentation may also enhance the food’s nutritional profile by creating new nutrients and allowing existing ones to be absorbed more easily.
Further, fermented foods contain probiotics, which are beneficial for our gut microbiome.
5 other tips to get your fresh fix
Although alternatives to fresh such as canned or frozen fruit and vegetables are good substitutes, if you’re looking to get more fresh produce into your diet on a tight budget, here are some things you can do.
1. Buy in season
Based on supply and demand principles, buying local seasonal vegetables and fruit will always be cheaper than those that are imported out of season from other countries.
2. Don’t shun the ugly fruit and vegetables
Most supermarkets now sell “ugly” fruit and vegetables, that are not physically perfect in some way. This does not affect the levels of nutrients in them at all, or their taste.
Buying fruit and vegetables during the right season will be cheaper. August de Richelieu/Pexels 3. Reduce waste
On average, an Australian household throws out A$2,000–$2,500 worth of food every year. Fruit, vegetables and bagged salad are the three of the top five foods thrown out in our homes. So properly managing fresh produce could help you save money (and benefit the environment).
To minimise waste, plan your meals and shopping ahead of time. And if you don’t think you’re going to get to eat the fruit and vegetables you have before they go off, freeze them.
4. Swap and share
There are many websites and apps which offer the opportunity to swap or even pick up free fresh produce if people have more than they need. Some local councils are also encouraging swaps on their websites, so dig around and see what you can find in your local area.
5. Gardening
Regardless of how small your garden is you can always plant produce in pots. Herbs, rocket, cherry tomatoes, chillies and strawberries all grow well. In the long run, these will offset some of your cost on fresh produce.
Plus, when you have put the effort in to grow your own produce, you are less likely to waste it.

The Vagus Nerve (And How You Can Make Use Of 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.
The Vagus Nerve: The Brain-Gut Highway
The longest cranial nerve is the vagus nerve; it runs all the way from your brain to your colon. It’s very important, and (amongst other tasks) it largely regulates your parasympathetic nervous system, and autonomous functions like:
- Breathing
- Heart rate
- Vasodilation & vasoconstriction
- Blood pressure
- Reflex actions (e.g. coughing, sneezing, swallowing, vomiting, hiccuping)
That’s great, but how does knowing about it help us?
Because of vagal maneuvers! This means taking an action to stimulate the vagus nerve, and prompt it to calm down various bodily functions that need calming down. This can take the form of:
- Massage
- Electrostimulation
- Diaphragmatic breathing
Massage is perhaps the simplest; “vagus” means “wandering”, and the nerve is accessible in various places, including behind the ears. That’s the kind of thing that’ easier to show than tell, though, so we’ll include a video at the end.
Electrostimulation is the fanciest, and has been used to treat migraines and cluster headaches. Check out, for example:
Update on noninvasive neuromodulation for migraine treatment-Vagus nerve stimulation
Diaphragmatic breathing means breathing from the diaphragm—the big muscular tissue that sits under your lungs. You might know it as “abdominal breathing”, and refers to breathing “to the abdomen” rather than merely to the chest.
Even though your lungs are obviously in your chest not your abdomen, breathing with a focus on expanding the abdomen (rather than the chest) when breathing in, will result in much deeper breathing as the diaphragm allows the lungs to fill downwards as well as outwards.
Why this helps when it comes to the vagus nerve is simply that the vagus nerve passes by the diaphragm, such that diaphragmatic breathing will massage the vagus nerve deep inside your body.
More than just treating migraines
Vagus nerve stimulation has also been researched and found potentially helpful for managing:
- Depression, inflammation, and heart disease
- Diabetes and glycemic issues in general
- Multiple sclerosis and autoimmune disease in general
- Alzheimer’s disease and dementia in general
- Rheumatoid arthritis (we already mentioned inflammation and autoimmune diseases, but this is an interesting paper so we included it)
All this is particularly important as we get older, because vagal response reduces with age, and vagus nerve stimulation, which improves vagal tone, makes it easier not just to manage the aforementioned maladies, but also simply to relax more easily and more deeply.

Alzheimer’s Causative Factors To Avoid
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.
The Best Brains Bar Nun?
This is Dr. David Snowdon. He’s an epidemiologist, and one of the world’s foremost experts on Alzheimer’s disease. He was also, most famously, the lead researcher of what has become known as “The Nun Study”.
We recently reviewed his book about this study:
…which we definitely encourage you to check out, but we’ll do our best to summarize its key points today!
Reassurance up-front: no, you don’t have to become a nun
The Nun Study
In 1991, a large number (678) of nuns were recruited for what was to be (and until now, remains) the largest study of its kind into the impact of a wide variety of factors on aging, and in particular, Alzheimer’s disease.
Why it was so important: because the nuns were all from the same Order, had the same occupation (it’s a teaching Order), with very similar lifestyles, schedules, socioeconomic status, general background, access to healthcare, similar diets, same relationship status (celibate), same sex (female), and many other factors also similar, this meant that most of the confounding variables that confound other studies were already controlled-for here.
Enrollment in the study also required consenting to donating one’s brain for study post-mortem—and of those who have since died, indeed 98% of them have been donated (the other 2%, we presume, may have run into technical administrative issues with the donation process, due to the circumstances of death and/or delays in processing the donation).
How the study was undertaken
We don’t have enough space to describe the entire methodology here, but the gist of it is:
- Genetic testing for relevant genetic factors
- Data gathered about lives so far, including not just medical records but also autobiographies that the nuns wrote when they took their vows (at ages 19–21)
- Extensive ongoing personal interviews about habits, life choices, and attitudes
- Yearly evaluations including memory tests and physical function tests
- Brain donation upon death
What they found
Technically, The Nun Study is still ongoing. Of the original 678 nuns (aged 75–106), three are still alive (based on the latest report, at least).
However, lots of results have already been gained, including…
Genes
A year into the study, in 1992, the “apolipoprotein E” (APOE) gene was established as a likely causative factor in Alzheimer’s disease. This is probably not new to our readers in 2024, but there are interesting things being learned even now, for example:
The Alzheimer’s Gene That Varies By Race & Sex
…but watch out! Because also:
Alzheimer’s Sex Differences May Not Be What They Appear
Words
Based on the autobiographies written by the nuns in their youth upon taking their vows, there were two factors that were later correlated with not getting dementia:
- Longer sentences
- Positive outlook
- “Idea density”
That latter item means the relative linguistic density of ideas and complexity thereof, and the fluency and vivacity with which they were expressed (this was not a wishy-washy assessment; there was a hard-science analysis to determine numbers).

…for specific, evidence-based ways to tweak your reading to fight cognitive decline.
Food
While the dietary habits of the nuns were fairly homogenous, those who favored eating more and cooked greens, beans, and tomatoes, lived longer and with healthier brains.
See also: Brain Food? The Eyes Have It!
Other aspects of brain health & mental health
The study also found that nuns who avoided stroke and depression, were also less likely to get dementia.

- Two Things You Can Do To Improve Stroke Survival Chances
- Depression, And The Mental Health First-Aid That You’ll Hopefully Never Need
- Behavioral Activation Against Depression & Anxiety
Community & Faith
Obviously, in this matter the nuns were quite a homogenous group, scoring heavily in community and faith. What’s relevant here is the difference between the nuns, and other epidemiological studies in other groups (invariably not scoring so highly).
Community & faith are considered, separately and together, to be protective factors against dementia.
Faith may be something that “you have it or you don’t” (we’re a health science newsletter, not a theological publication, but for the interested, philosopher John Stuart Mill’s 1859 essay “On Liberty“ makes a good argument for it not being something one can choose, prompting him to argue for religious tolerance, on the grounds that religious coercion is a futile effort precisely because a person cannot choose to dis/believe something)
…but community can definitely be chosen, nurtured, and grown. We’ve written about this a bit before:

Apricots vs Plums – 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 apricots to plums, we picked the apricots.
Why?
Both are great, but it wasn’t close!
In terms of macros, apricots have more fiber, protein, and carbs, with their fiber:carb ratio also giving them the lower glycemic index (although, as usual for any whole fruit, neither are going to give anyone metabolic disease). In any case, by the numbers, and especially for having more fiber, apricots win this category.
In the category of vitamins, apricots have more of vitamins A, B1, B2, B3, B5, B6, B7, B9, C, E, and choline, while plums have more vitamin K. A clear win for apricots.
When it comes to minerals, apricots have more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while plums are not higher in any mineral. Another hands-down win for apricots.
Looking at polyphenols, both have an abundance of many, especially assorted flavanols, including quercetin. However, plums additionally have some anthocyanins (whence the color), so they get a marginal victory in this round.
Still, adding up the sections, it’s a 3:1 win for apricots. Of course, do enjoy either or both, though; diversity is good!

Infections, Heart Failure, & More
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.
Some health news to round off the week:
The Infection That Leads To Heart Failure
It’s long been held that, for example, flossing reduces heart disease risk, with the hypothesis being that if plaque bacteria enter the blood stream, well, that’s an even worse place for plaque bacteria to be. Now, with much more data, attention has turned to
- actual infections, and
- actual heart failure
Way to up the ante! And, it holds true regardless of what kind of infection. So, you might think that a UTI, for example, is surely “downstream” and should not affect the heart, but it does. Because of this, researchers currently believe that it is not the infection itself, so much as the body’s inflammation response to infection, that leads to the heart failure. Which is reasonable, because, for example, atherosclerosis is made mostly not of cholesterol itself, but rather mostly of dead immune cells that got stuck in the cholesterol.
Moreover, it’s not so much about the acute inflammatory response (which is almost always a good thing, circumstantially), but rather that after cases where an infection managed to take hold, the immune system can then often stay on high alert for many years alter. Long COVID is an obvious recent example of this, but it’s hardly a new phenomenon; see for example post-polio syndrome, and consider how many more such post-infection maladies are likely to exist that never got a name because they flew under the radar or got diagnosed as fibromyalgia or something (fibromyalgia is a common diagnosis doctors give when they acknowledge something’s wrong, and it causes pain and exhaustion, but they don’t know what, and it appears to be stable—so while it can be helpful to put a name to the collection of symptoms, it’s a non-diagnosis diagnosis on the doctors’ part. It’s saying “I diagnose you with hurty tiredness”).
The take-away from all this? Avoid infections, for your heart’s sake, and if you do get an infection, take it seriously even if it’s minor. The safe amount of infection is “no infection”.

Cold Water Immersion: Hot Or Not?
The evidence is clear for some benefits; for others, not so much:
- It’s great (if you’re already in fair health, and definitely not if you have a heart condition) to improve circulation and stress response
- There may be some benefits to immune function, but however reasonable the hypothesis, actual evidence is thin on the ground
- The oft-hyped mood benefits are a) marginal b) short-lived, with benefits fading after 3 months of regular cold baths/showers/etc

The Unspoken Trials Of Going To The Gym (While Being A Woman)
Public health decision-makers often think that getting people to go to the gym more is a matter of public information, or perhaps branding. Some who have their thinking heads on might even realize that there may be economic factors for many. But for women, there’s an additional factor—or rather, an additionally prominent factor. The study we’ll link started with this observation (please read it in the voice of your favorite nature documentary narrator):
❝Despite an increase in gym memberships, women are less active than men and little is known about the barriers women face when navigating gym spaces.❞
What then, of these shy, elusive creatures that make up a mere 51% of the world’s population?
A medium-sized (n=279) study of women, of whom 84% being current gym-goers, reported often feeling “judged for their appearance or performance, as well as having to fight for space in the gym and to be taken seriously, while navigating harassment and unsolicited comments from men”
Even gym attire becomes an issue:
❝Aligning with previous literature, women often chose attire based on comfort and functionality. However, their choices were also influenced by comparisons with others or fear of judgement for wearing non-branded attire or looking too put together. Many women also chose gym attire to hide perceived problem areas or avoid appearance concerns, including visible sweat stains.❞
…which main seem silly; you’re at the gym, of course you’re going to sweat, but if you’re the only one with visible sweat stains, then there can be social consequences (bad ones).
Similarly, there’s a “damned if you do; damned if you don’t” when it comes to working out while fat—on the one hand, society conflates fatness with laziness; on the other, it can be extra intimidating to be the only fat person in a gym full of people who look like they’re going to audition for a superhero movie.
❝In the gym, just like in other areas of life, women often feel stuck between being seen as ‘too much’ and ‘not enough’, dealing with judgement about how they look, how they perform, and even how much space they take up. Even though the pressure to be super thin is decreasing, the growing focus on being muscular and athletic is creating new challenges. It is pushing unrealistic standards that can negatively affect women’s body image and overall well-being.❞
Writer’s note: I live a few minutes walk from my nearest gym, and I work out at home instead. This way, if I want to do yoga in my pajamas, I can. If I want to use my treadmill naked and watch my T+A bounce in the mirror, I can. If I want to lift weights in the dress I happened to be wearing, I can. Alas that I can’t swim at home!
