How to keep your teeth young
The association between aging and teeth is so well-established that it’s entered popular idiom, “too long in the tooth”, and when it comes to visual representations, false teeth are well-associated with old age.
And yet, avoiding such outcomes does not get anywhere near so much attention as, say, avoiding wrinkles or hair loss.
At 10almonds, we’ve covered general dental health before, in a three-part series:
- Toothpastes & Mouthwashes: Which Help And Which Harm?
- Flossing, Better (And Easier!)
- Less Common Oral Hygiene Options
Today, we’re going to be looking specifically at keeping our teeth young. What if you have lost your teeth already? Well, gum health remains important, and it’s foundational for everyone, so…
Look after your gums first and last
Hollywood’s most “perfect” whites would be nothing without the gums holding them in place. So, set aside the cosmetic whitening products that often harm gums (anything containing bleach / hydrogen peroxide, is generally a bad idea), andinstead focus on your gums.
As for avoiding gum disease (periodontitis)?
❝In conclusion, periodontitis might enhance the association of biological aging with all-cause mortality in middle-aged and older adults.
Hence, maintaining and enhancing periodontal health is expected to become an intervention to slow aging and extend life span.❞
Source: Does Periodontitis Affect the Association of Biological Aging with Mortality?
Ways to look after gum health include the obvious “floss” and “brush often” and “use fluoride toothpaste”, along with other options we covered in our “Less Common Oral Hygiene Options” article above.
Also important: don’t smoke. It is bad for everything, and this is no exception.
We expect we probably don’t have many subscribers who smoke, but if you do, please consider making quitting a priority.

Consider supplementing with collagen
Everyone’s all about the calcium and vitamin D for bones (and teeth), but a large part of the mass of both is actually collagen. And unlike calcium, which most people not living in a food desert get plenty of, or vitamin D, which is one of the most popular supplements around, collagen is something that gets depleted as we get older. We’ve written about its importance for bones:
We Are Such Stuff As Fish Are Made Of—Collagen’s benefits are more than skin deep
And as for its role in combatting gum disease and tooth loss:
Nanoscale Dynamics of Streptococcal Adhesion to AGE-Modified Collagen
By the way, that “AGE” there isn’t about chronological age; it’s about advanced glycation end-products. Those are also something you can and should avoid:
A different kind of “spit and polish”
We imagine you have the “polishing” part in hand; that’s tooth-brushing, of course. But spit?
Saliva is hugely important for our oral health, but it’s not something most of us think about a lot. For example, you might not have known (or might have known but not thought much about) that many common medications affect our saliva, including many blood pressure medications and antidepressants:
Impact of ageing and drug consumption on oral health
Because there are so many possibilities, this is the kind of thing to check with your pharmacist or doctor about. But as a rule, if you take a medication whose side-effects include “dry mouth”, this might be you.
Here’s a really useful (academic) article that covers what drugs cause this, how to diagnose it, and what can be done about it:
Hyposalivation in Elderly Patients
If something’s difficult, find a way to make it easier
Sometimes, as we get older, some things that used to be easy, aren’t. We can lose strength, coordination, manual dexterity, memory, attention, and more. Obviously, we try not to, and do what we can to keep ourselves in good health.
But, if you do have some disability that makes for example brushing and/or flossing difficult to do consistently and/or well, consider talking to your doctor to see if there are assistive devices that can help, or some other kind of support that could allow you to do what you need to.
There’s never any shame in getting help if we need it.
Take care!

Cows’ Milk, Bird Flu, & You
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.
When it comes to dairy products, generally speaking, fermented ones (such as most cheeses and yogurts) are considered healthy in moderation, and unfermented ones have their pros and cons that can be argued and quibbled “until the cows come home”. We gave a broad overview, here:
Furthermore, you may recall that there’s some controversy/dissent about when human babies can have cows’ milk:
When can my baby drink cow’s milk? It’s sooner than you think
So, what about bird flu now?
Earlier this year, the information from the dairy industry was that it was nothing to be worried about for the time being:
Bird Flu Is Bad for Poultry and Dairy Cows. It’s Not a Dire Threat for Most of Us — Yet.
More recently, the latest science has found:
❝We found a first-order decay rate constant of −2.05 day–1 equivalent to a T99 of 2.3 days. Viral RNA remained detectable for at least 57 days with no degradation. Pasteurization (63 °C for 30 min) reduced infectious virus to undetectable levels and reduced viral RNA concentrations, but reduction was less than 1 log10.
The prolonged persistence of viral RNA in both raw and pasteurized milk has implications for food safety assessments and environmental surveillance❞
You can find the study here:
Infectivity and Persistence of Influenza A Virus in Raw Milk
In short: raw milk keeps the infectious virus; pasteurization appears to render it uninfectious, though viral RNA remains present.
This is relevant, because of the bird flu virus being found in milk:
World Health Organization | H5N1 strain of bird flu found in milk
To this end, a moratorium has been placed on the sale of raw milk, first by the California Dept of Public Health (following an outbreak in California):
California halts sales of raw milk due to bird flu virus contamination
And then, functionally, by the USDA, though rather than an outright ban, it’s requiring testing for the virus:
USDA orders testing of milk supply for presence of bird flu virus
So, is pasteurized milk safe?
The official answer to this, per the FDA, is… Honestly, a lot of hand-wringing and shrugging. What we do know is:
- the bird flu virus has been found in pasteurized milk too
- the test for this is very sensitive, and has the extra strength/weakness that viral fragments will flag it as a positive
- it is assumed that the virus was inactivated by the pasteurization process
- it could, however, have been the entire virus, the test simply does not tell us which
In the FDA’s own words:
❝The pasteurization process has served public health well for more than 100 years. Even if the virus is detected in raw milk, pasteurization is generally expected to eliminate pathogens to a level that does not pose a risk to consumer health❞
So, there we have it: the FDA does not have a reassurance exactly, but it does have a general expectation.

How to Fall Back Asleep After Waking Up in the Middle of the Night
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.
Dr. Michael Bruce, the Sleep Doctor, addresses a common concern: waking up in the middle of the night and struggling to fall back asleep.
Understanding the Wake-Up
Firstly, why are we waking up during the night?
Waking up between 2 AM and 3 AM is said to be normal, and linked to your core body temperature. As your body core temperature drops, to trigger melatonin release, and then rises again, you get into a lighter stage of sleep. This lighter stage of sleep makes you more prone to waking up.
Note, there are also some medical conditions (such as sleep apnea) that can cause you to wake up during the night.
But, what can we do about it? Aside from constantly shifting sleeping position (Should I be sleeping on my back? On my left? Right?)
Avoid the Clock
The first step is to resist the urge to check the time. It’s easy to be tempted to have a look at the clock, however, doing so can increase anxiety, making it harder to fall back asleep. As Dr. Bruce says, sleep is like love—the less you chase it, the more it comes.
It may be useful to point your alarm clock (if you still have one of those) the opposite direction to your bed.
Embracing Non-Sleep Deep Rest (NSDR)
Whilst this may not help you fall back asleep, it’s worth pointing out that just lying quietly in the dark without moving still offers rejuvenation. This revujenating stage is called Non-Sleep Deep Rest (otherwise known as NSDR)
If you’re not familiar with NSDR, check out our overview of Andrew Huberman’s opinions on NSDR here.
So, you can reassure yourself that whilst you may not be asleep, you are still resting.
Keep Your Heart Rate Down
To fall back asleep, it’s best if your heart rate is below 60 bpm. So, Dr. Bruce advises avoiding void getting up unnecessarily, as moving around can elevate your heart rate.
On a similar vain, he introduces the 4-7-8 breathing technique, which is designed to lower your heart rate. The technique is simple:
- Breathe in for 4 seconds.
- Hold for 7 seconds.
- Exhale for 8 seconds.
Repeat this cycle gently to calm your body and mind.
As per any of our Video Breakdowns, we only try to capture the most important pieces of information in text; the rest can be garnered from the video itself:
Wishing you a thorough night’s rest!

Leek vs Scallions – 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 leek to scallions, we picked the leek.
Why?
In terms of macros, scallions might have a point: scallions have the lower glycemic index, thanks to leek having more carbs for the same amount of fiber. That said, leek already has a low glycemic index, so this is not a big deal.
When it comes to vitamins, leek has more of vitamins B1, B2, B3, B5, B6, B9, E, and choline, while scallions have more of vitamins A, C, and K. Noteworthily, a cup of chopped leek already provides the daily dose of vitamins A and K, and the difference in levels of vitamin C is minimal. All in all, an easy 8:3 win for leeks here, even without taking that into account.
In the category of minerals, leek has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and selenium, while scallions have a little more zinc.
Both of these allium-family plants (i.e., related to garlic) have an abundance of polyphenols, especially kaempferol.
Of course, enjoy whatever goes best with your meal, but if you’re looking for nutritional density, then leek is where it’s at.

Hot And Sour Shiitake Soup
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.
This is a popular, easy, and delicious soup that nonetheless is not found in many western kitchens, despite being enjoyed in restaurants/take-out. Best of all, making it at home means that you know all the ingredients, can account for quality, and also can customize it per your preferences (i.e. how much heat/sourness you like).
You will need
- 3 cups shiitake mushrooms, sliced
- 3 cups bok choy, chopped
- 2 cups cherry tomatoes, quartered
- 1 cup carrot, grated
- 3 spring onions, chopped
- 2 shallots, sliced lengthways
- 2 serrano chilis (or similar), sliced thinly
- 2 tbsp apple cider vinegar
- 1 tbsp lemon juice
- 1 tbsp fresh ginger, sliced into 1″ strips
- 1 tsp black pepper, coarse ground
- ½ bulb garlic, crushed
- 6 cups low-sodium vegetable stock. Ideally you will have made it yourself from vegetable cuttings that you saved in the freezer until you had enough to make stock from, but if that’s not an option, then low-sodium vegetable stock cubes can be purchased and used.
- Garnish: ¼ cup (or 4 tbsp) cilantro, chopped, or if you have the soap gene, then this time we recommend chopped basil as the subsitution
Method
(we suggest you read everything at least once before doing anything)
1) Put the ginger in a big pot with the stock; cover and simmer for about 20 minutes (otherwise the ginger flavor will remain mostly concentrated in the ginger strips).
2) Bring it to a boil and add the bok choy, mushrooms, shallots, chili peppers, and the carrot; simmer for another 5 minutes
3) Add the remaining ingredients except for the garnish, and simmer for another 5 minutes
4) Serve, adding the garnish
Enjoy!

10 Powerful Tips To Improve Lymph Flow – by Laurel West
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 lymphatic system is a large part of the body’s “clean-up” system, as well having an important role in fighting cancer specifically. As such, while it doesn’t get nearly as much popular attention as our circulatory system or our nervous system, say, it is critically important.
The author, a massage therapist, knows her stuff when it comes to lymph, and shows that here.
As this is a very lean book, weighing in at a mere 87 pages, you can imagine it gets straight to the point.
So will we! The titular “10 powerful tips” are:
- Drink water
- Matcha meditation
- Breathwork
- Dry brushing
- Hydrotherapy
- Stretching
- Sweating
- Lymphatic facial massage
- Advanced lymphatic massage
- Anti-inflammatory diet
Of course, she does explain each of those; some are more obvious than others; “drink water” takes less explanation than “advanced lymphatic massage”, say.
The style is, as you might expect, concise. It’s more of a primer than a textbook, and it does communicate its ideas clearly.
Bottom line: if you’d like to manage your lymph better, this book is an excellent way to get started.
Click here to check out 10 Powerful Tips To Improve Lymph Flow, and improve your lymph flow.

10 Ways To Delay Aging
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.
This is Dr. Colin Rose; he is a Senior Associate of the Royal Society of Medicine. He’s also a main contributor to EduScience, a program funded by the E.U. which is designed to enhance the teaching and learning of science in schools in Europe.
His most recent work has been about aging—and how to delay it. We also reviewed his latest book, here:
Delay Ageing – by Dr. Colin Rose
So, what does he want us to know? The key lies in his compilation of ten ways in which we age on a cellular level, and what we can to do slow each one of those:
Damage to DNA accumulates
While DNA can get damaged without any external stimulus to cause that, there are a lot of modifiable factors that we can do to reduce DNA damage. The list is easy: if it causes cancer, it causes aging.
Thus, check out: Stop Cancer 20 Years Ago
Cells become senescent
Our cells are replaced all the time; some sooner than others, but all of them at some point. The problem occurs when cells are outliving their usefulness. If a cell becomes completely immortal, that is cancer, but happily most don’t. Nevertheless, having senescent (aging) cells in the body means that those senescent cells are what get copied forwards by mitosis, and our DNA becomes like a photocopy of a tattered old photocopy of a tattered old photocopy. Which, needless to say, is not good for our health. So, the best thing to do is to kill them earlier:
Yes, really: Fisetin: The Anti-Aging Assassin
Mitochondria become dysfunctional
Without properly functional mitochondria, no living human cell can do its job properly.

Beneficial genes are switched off, harmful genes are on
It’s easy to think of our genes as being immutable, but epigenetics means that our environment (amongst other factors) can mean that our gene expression changes.
Imagine it this way: your genes are a set of instructions for your body. However, your body will act or not on those instructions, depending on other factors. Hormones often play a big part in this; for example sex hormones tell the body which set of genetic instructions to read (and thus what kind of body to build/rebuild), and cortisol or oxytocin can tell the body which set of contingency plans to activate or suppress (respectively). A milder example is gray hair; genes have the program for it, but many other factors inform the body when, if, and how to do it.
Of more concern when it comes to aging is what goes on with more critical systems, such as the brain, in which the aforementioned DNA damage can cause unhelpful instructions to get interpreted, resulting in epigenetic changes that in turn facilitate age-related degeneration.
As to what can be done, see : Klotho: Unzipping The Genes Of Aging?
Stem cells become exhausted
Stem cells can become different kinds of cells, and thus they’re very useful for maintaining a healthy body. However, they get depleted with age. We can slow down the rate of loss, though; for example, intermittent fasting can help:
Per Dr. Li’s 5 Ways To Beat Cancer (And Other Diseases)
And for more detail, see:
Doctor’s Tip: Regeneration (stem cells) — one of your body’s five defense systems
(complete with lists of foods to eat or avoid for stem cell health)
Cells fail to communicate properly
Cells need to talk to each other constantly, to continue doing their jobs. We are one big organism, after all, and not a haphazard colony of the countless cells that constitute such. However, cell signalling gets worse with age, which in turn precipitates others age-related problems. Fortunately, there are nutrients that can improve cellular communication.
For example: PS, We Love You ← this is about phosphatidylserine, also called “PS”
Telomeres become shorter
These protective caps on our DNA suffer the wear-and-tear so that our DNA doesn’t have to. However, as they get shorter, the DNA can start suffering damage. For this reason, telomere length is considered one of the most “Gold Standard” markers of cellular aging.
Here’s what can be done for that: The Stress Prescription (Against Aging!)
The body fails to sense nutritional intake properly
This is mostly about insulin signalling (though problems can occur in other systems too, but we only have so much room here), so it’s important to take care of that.
See: Turn Back The Clock On Insulin Resistance
Proteins accumulate errors
This is due to DNA damage, of course, but there are specific things that can reduce protein error accumulation; see for example:
A quick fix – preventing protein errors extends lifespan

The microbiome becomes unbalanced
We at 10almonds often mention that gut health affects pretty much every other kind of health, and it’s true for aging as well. So, take care of that microbiome!
