Has your doctor asked you to stick out your tongue and say “aaah”? While the GP assesses your throat, they’re also checking out your tongue, which can reveal a lot about your health.
The doctor will look for any changes in the tongue’s surface or how it moves. This can indicate issues in the mouth itself, as well as the state of your overall health and immunity.
But there’s no need to wait for a trip to the doctor. Cleaning your tongue twice a day can help you check how your tongue looks and feels – and improve your breath.
What does a healthy tongue look like?
Our tongue plays a crucial role in eating, talking and other vital functions. It is not a single muscle but rather a muscular organ, made up of eight muscle pairs that help it move.
The surface of the tongue is covered by tiny bumps that can be seen and felt, called papillae, giving it a rough surface.
These are sometimes mistaken for taste buds – they’re not. Of your 200,000-300,000 papillae, only a small fraction contain taste buds. Adults have up to 10,000 taste buds and they are invisible to the naked eye, concentrated mainly on the tip, sides and back of the tongue. https://www.youtube.com/embed/uYvpUl7li9Y?wmode=transparent&start=0
A healthy tongue is pink although the shade may vary from person to person, ranging from dark to light pink.
A small amount of white coating can be normal. But significant changes or discolouration may indicate a disease or other issues.
How should I clean my tongue?
Cleaning your tongue only takes around 10-15 seconds, but it’s is a good way to check in with your health and can easily be incorporated into your teeth brushing routine.
You can clean your tongue by gently scrubbing it with a regular toothbrush. This dislodges any food debris and helps prevent microbes building up on its rough textured surface.
Or you can use a special tongue scraper. These curved instruments are made of metal or plastic, and can be used alone or accompanied by scrubbing with your toothbrush.
Your co-workers will thank you as well – cleaning your tongue can help combat stinky breath. Tongue scrapers are particularly effective at removing the bacteria that commonly causes bad breath, hidden in the tongue’s surface.
What’s that stuff on my tongue?
So, you’re checking your tongue during your twice-daily clean, and you notice something different. Noting these signs is the first step. If you observe any changes and they worry you, you should talk to your GP.
Here’s what your tongue might be telling you.
White coating
Developing a white coating on the tongue’s surface is one of the most common changes in healthy people. This can happen if you stop brushing or scraping the tongue, even for a few days.
In this case, food debris and microbes have accumulated and caused plaque. Gentle scrubbing or scraping will remove this coating. Removing microbes reduces the risk of chronic infections, which can be transferred to other organs and cause serious illnesses.
Yellow coating
This may indicate oral thrush, a fungal infection that leaves a raw surface when scrubbed.
Oral thrush is common in elderly people who take multiple medications or have diabetes. It can also affect children and young adults after an illness, due to the temporary suppression of the immune system or antibiotic use.
If you have oral thrush, a doctor will usually prescribe a course of anti-fungal medication for at least a month.
Black coating
Smoking or consuming a lot of strong-coloured food and drink – such as tea and coffee, or dishes with tumeric – can cause a furry appearance. This is known as a black hairy tongue. It’s not hair, but an overgrowth of bacteria which may indicate poor oral hygiene.
Pink patches
Pink patches surrounded by a white border can make your tongue look like a map – this is called “geographic tongue”. It’s not known what causes this condition, which usually doesn’t require treatment.
Pain and inflammation
A red, sore tongue can indicate a range of issues, including:
- nutritional deficiencies such as folic acid or vitamin B12
- diseases including pernicious anaemia, Kawasaki disease and scarlet fever
- inflammation known as glossitis
- injury from hot beverages or food
- ulcers, including cold sores and canker sores
- burning mouth syndrome.
Dryness
Many medications can cause dry mouth, also called xerostomia. These include antidepressants, anti-psychotics, muscle relaxants, pain killers, antihistamines and diuretics. If your mouth is very dry, it may hurt.
What about cancer?
White or red patches on the tongue that can’t be scraped off, are long-standing or growing need to checked out by a dental professional as soon as possible, as do painless ulcers. These are at a higher risk of turning into cancer, compared to other parts of the mouth.
Oral cancers have low survival rates due to delayed detection – and they are on the rise. So checking your tongue for changes in colour, texture, sore spots or ulcers is critical.

Deskbound – by Kelly Starrett and Glen Cordoza
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 all heard that “sitting is the new smoking”, and whether or not that’s an exaggeration (the jury’s out), one thing that is clear is that sitting is very bad.
Popular advice is “here’s how to sit with good posture and stretch your neck sometimes”… but that advice tends to come from companies that pay people to sit for a long time. They might not be the a very unbiased source.
Starrett and Cordoza offer better. After one opening chapter covering the multifarious ways sitting ruins our health, the rest of the book is all advice, covering:
- The principles of how the body is supposed to be
- The most important movements that we should be doing
- A dynamic workstation setup
- This is great, because “get a standing desk” tends to present more questions than answers, and can cause as much harm as good if done wrong
- The authors also cover how to progressively cut down on sitting, rather than try to go cold-turkey.
- They also recognize that not everyone can stand at all, and…
- Optimizing the sitting position, for when we must sit
- Exercises to maintain our general mobility and compensate about as well as we can for the body-unfriendly nature of modern life.
The book is mostly explanations, so at 682 pages, you can imagine it’s not just “get up, lazybones!”. Rather, things are explained in such detail (and with many high-quality medical diagrams) so that we can truly understand them.
Most of us have gone through life knowing we should have “better posture” and “move more”… but without the details, that can be hard to execute correctly, and worse, we can even sabotage our bodies unknowingly with incorrect form.
This book straightens all that out very comprehensively, and we highly recommend it.

Black Pepper’s Impressive Anti-Cancer Arsenal
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.
Black Pepper’s Impressive Anti-Cancer Arsenal (And More)
Piperine, a compound found in Piper nigrum (black pepper, to its friends), has many health benefits. It’s included as a minor ingredient in some other supplements, because it boosts bioavailability. In its form as a kitchen spice, it’s definitely a superfood.
What does it do?
First, three things that generally go together:
These things often go together for the simple reason that oxidative stress, inflammation, and cancer often go together. In each case, it’s a matter of cellular wear-and-tear, and what can mitigate that.
For what it’s worth, there’s generally a fourth pillar: anti-aging. This is again for the same reason. That said, black pepper hasn’t (so far as we could find) been studied specifically for its anti-aging properties, so we can’t cite that here as an evidence-based claim.
Nevertheless, it’s a reasonable inference that something that fights oxidation, inflammation, and cancer, will often also slow aging.
Special note on the anti-cancer properties
We noticed two very interesting things while researching piperine’s anti-cancer properties. It’s not just that it reduces cancer risk and slows tumor growth in extant cancers (as we might expect from the above-discussed properties). Let’s spotlight some studies:
It is selectively cytotoxic (that’s a good thing)
Piperine was found to be selectively cytotoxic to cancerous cells, while not being cytotoxic to non-cancerous cells. To this end, it’s a very promising cancer-sniper:
Piperine as a Potential Anti-cancer Agent: A Review on Preclinical Studies
It can reverse multi-drug resistance in cancer cells
P-glycoprotein, found in our body, is a drug-transporter that is known for “washing out” chemotherapeutic drugs from cancer cells. To date, no drug has been approved to inhibit P-glycoprotein, but piperine has been found to do the job:
Targeting P-glycoprotein: Investigation of piperine analogs for overcoming drug resistance in cancer
What’s this about piperine analogs, though? Basically the researchers found a way to “tweak” piperine to make it even more effective. They called this tweaked version “Pip1”, because calling it by its chemical name,
((2E,4E)-5-(benzo[d][1,3]dioxol-5-yl)-1-(6,7-dimethoxy-3,4-dihydroisoquinolin-2(1 H)-yl)penta-2,4-dien-1-one)
…got a bit unwieldy.
The upshot is: Pip1 is better, but piperine itself is also good.
Other benefits
Piperine does have other benefits too, but the above is what we were most excited to talk about today. Its other benefits include:
- Neuroprotective effects (against Alzheimer’s, Parkinson’s, and more)
- Blood-sugar balancing / antidiabetic effect
- Good for gut microbiome diversity
- Heart health benefits, including cholesterol-balancing
- Boosts bioavailability of other nutrients/drugs

CBD Against Diabetes!
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
❝CBD for diabetes! I’ve taken CBD for body pain. Did no good. Didn’t pay attention as to diabetes. I’m type 1 for 62 years. Any ideas?❞
Thanks for asking! First up, for reference, here’s our previous main feature on the topic of CBD:
CBD Oil: What Does The Science Say?
There, we touched on CBD’s effects re diabetes:
in mice / in vitro / in humans
In summary, according to the above studies, it…
- lowered incidence of diabetes in non-obese diabetic mice. By this they mean that pancreatic function improved (reduced insulitis and reduced inflammatory Th1-associated cytokine production). Obviously this has strong implications for Type 1 Diabetes in humans—but so far, just that, implications (because you are not a mouse).
- attenuated high glucose-induced endothelial cell inflammatory response and barrier disruption. Again, this is promising, but it was an in vitro study in very controlled lab conditions, and sometimes “what happens in the Petri dish, stays in the Petri dish”—in order words, these results may or may not translate to actual living humans.
- Improved insulin response ← is the main take-away that we got from reading through their numerical results, since there was no convenient conclusion given. Superficially, this may be of more interest to those with type 2 diabetes, but then again, if you have T1D and then acquire insulin resistance on top of that, you stand a good chance of dying on account of your exogenous insulin no longer working. In the case of T2D, “the pancreas will provide” (more or less), T1D, not so much.
So, what else is there out there?
The American Diabetes Association does not give a glowing review:
❝There’s a lot of hype surrounding CBD oil and diabetes. There is no noticeable effect on blood glucose (blood sugar) or insulin levels in people with type 2 diabetes. Researchers continue to study the effects of CBD on diabetes in animal studies. ❞
~ American Diabetes Association
Source: ADA | CBD & Diabetes
Of course, that’s type 2, but most research out there is for type 2, or else have been in vitro or rodent studies (and not many of those, at that).
Here’s a relatively more recent study that echoes the results of the previous mouse study we mentioned; it found:
❝CBD-treated non-obese diabetic mice developed T1D later and showed significantly reduced leukocyte activation and increased FCD in the pancreatic microcirculation.
Conclusions: Experimental CBD treatment reduced markers of inflammation in the microcirculation of the pancreas studied by intravital microscopy. ❞
~ Dr. Christian Lehmann et al.
Read more: Experimental cannabidiol treatment reduces early pancreatic inflammation in type 1 diabetes
…and here’s a 2020 study (so, more recent again) that was this time rats, and/but still more promising, insofar as it was with rats that had full-blown T1D already:
Read in full: Two-weeks treatment with cannabidiol improves biophysical and behavioral deficits associated with experimental type-1 diabetes
Finally, a paper in July 2023 (so, since our previous article about CBD), looked at the benefits of CBD against diabetes-related complications (so, applicable to most people with any kind of diabetes), and concluded:
❝CBDis of great value in the treatment of diabetes and its complications. CBD can improve pancreatic islet function, reduce pancreatic inflammation and improve insulin resistance. For diabetic complications, CBD not only has a preventive effect but also has a therapeutic value for existing diabetic complications and improves the function of target organs❞
…before continuing:
❝However, the safety and effectiveness of CBD are still needed to prove. It should be acknowledged that the clinical application of CBD in the treatment of diabetes and its complications has a long way to go.
The dissecting of the pharmacology and therapeutic role of CBD in diabetes would guide the future development of CBD-based therapeutics for treating diabetes and diabetic complications❞
~ Ibid.
Now, the first part of that is standard ass-covering, and the second part of that is standard “please fund more studies please”. Nevertheless, we must also not fail to take heed—little is guaranteed, especially when it comes to an area of research where the science is still very young.
In summary…
It seems well worth a try, and with ostensibly nothing to lose except the financial cost of the CBD.
If you do, you might want to keep careful track of a) your usual diabetes metrics (blood sugar levels before and after meals, insulin taken), and b) when you took CBD, what dose, etc, so you can do some citizen science here.
Lastly: please remember our standard disclaimer; we are not doctors, let alone your doctors, so please do check with your endocrinologist before undertaking any such changes!

You might like our previous main feature:
How To Prevent And Reverse Type 2 Diabetes ← obviously this will not prevent or reverse Type 1 Diabetes, but avoiding insulin resistance is good in any case!
If you’re not diabetic and you’ve perhaps been confused throughout this article, then firstly thank you for your patience, and secondly you might like this quick primer:
The Sweet Truth About Diabetes: Debunking Diabetes Myths! ← this gives a simplified but fair overview of types 1 & 2
(for space, we didn’t cover the much less common types 3 & 4; perhaps another time we will)

Tuna Steak with Protein Salad
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.
Yes, it’s protein on protein today, and it’s all healthy.
You will need (per person)
- 1 tuna steak
- 1 400g/12oz can mixed beans, drained & rinsed
- 1 tsp capers
- 2 tsp black pepper, coarse ground
- 1 red chili, chopped
- 1 lime, cut into wedges
- ½ tsp white wine vinegar
- Extra virgin olive oil, for cooking
- Garnish: chopped parsley
Method
(we suggest you read everything at least once before doing anything)
1) Put the beans in a bowl, mixing in the capers, vinegar, and 1 tsp of the black pepper
2) Gently rub a little olive oil onto each side of the tuna steak, and season with the remainder of the black pepper (as in, the other tsp, not the rest of what you have in the house).
3) Heat a ridged grill pan until hot, and then cook the tuna for around 3 minutes on each side. Do not jiggle it! Do not slide it, and definitely do not stir it. Just gently turn it over when necessary. The edges should be cooked, and the inside should still be pink (it’s easy to forget when it comes from a can, but remember tuna is usually eaten raw)
4) Serve, sprinkling with the chopped chili and garnishing with the parsley. The lime wedges go on the side for squeezing at the table.
Enjoy!

Fitness Walking and Bodyweight Exercises – by Frank S. Ring
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 exercise manuals assume that the reader has a “basic” body (nothing Olympian, but nothing damaged either). As we get older, increasingly few of us fall into the “but nothing damaged either” category!
Here’s where Ring brings to bear his decades of experience as a coach and educator, and also his personal recovery from a serious back injury.
The book covers direct, actionable exercise advice (with all manner of detail), and also offers mental health tips he’s learned along the way.
Ring, like us, is a big fan of keeping things simple, so he focusses on “the core four” of bodyweight exercises:
- Pushups
- Squats
- Lunges
- Planks
These four exercises get a whole chapter devoted to them, though! Because there are ways to make each exercise easier or harder, or have different benefits. For example, adjustments include:
- Body angle
- Points of contact
- Speed
- Pausing
- Range of motion
This, in effect, makes a few square meters of floor (and perhaps a chair or bench) your fully-equipped gym.
As for walking? Ring enjoys and extols the health benefits, and/but also uses his walks a lot for assorted mental exercises, and recommends we try them too.
A fine book for anyone who wants to gain and/or maintain good health, but doesn’t pressingly want to join a gym or start pumping iron!

Hold Me Tight – by Dr. Sue Johnson
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 relationship books are quite wishy-washy. This one isn’t.
This one is evidenced-based (and heavily referenced!), and yet at the same time as being deeply rooted in science, it doesn’t lose the human touch.
Dr. Johnson has spent her career as a clinical psychologist and researcher; she’s the primary developer of Emotionally Focused Therapy (EFT), which has demonstrated its effectiveness in over 35 years of peer-reviewed clinical research. In other words, it works.
EFT—and thus also this book—finds roots in Attachment Theory. As such, topics this book covers include:
- Recognizing and recovering from attachment injury
- How fights in a relationship come up, and how they can be avoided
- How lot of times relationships end, it’s not because of fights, but a loss of emotional connection
- Building a lifetime of love instead, falling in love again each day
This book lays the groundwork for ensuring a strong, secure, ongoing emotional bond, of the kind that makes/keeps a relationship joyful and fulfilling.
Dr. Johnson has been recognized in her field with a Lifetime Achievement Award, and the Order of Canada.
