It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
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 😎
❝I watched a documentary recently on Fluoride in our drinking water & the dangers of it. Why are we poisoning our water?❞
This is a great question, and it certainly is controversial. It sounds like the documentary you watched was predominantly or entirely negative, but there’s a lot of science to back both sides of this, and it’s not even that the science is contradictory (it’s not). It’s that what differs is people’s opinions about whether benefiting one thing is worth creating a risk to another, and that means looking at:
- What is the risk associated with taking no action (error of omission)?
- What is the risk associated with taking an action (error of commission)?
The whole topic is worth a main feature, but to summarize a few key points:
- Water fluoridation is considered good for the prevention of dental cavities
- Water fluoridation aims to deliver fluoride and doses far below dangerous levels
- This requires working on consumer averages, though
- ”Where do we put the safety margins?” is to some extent a subjective question, in terms of trading off one aspect of health for another
- Too much fluoride can also be bad for the teeth (at least cosmetically, creating little white* spots)
- Detractors of fluoride tend to mostly be worried about neurological harm
- However, the doses in public water supplies are almost certainly far below the levels required to cause this harm.
- That said, again this is working on consumer averages, though.
- However, the doses in public water supplies are almost certainly far below the levels required to cause this harm.
- A good guide is: watch your teeth! Those white* spots will be “the canary in the coal mine” of more serious harm that could potentially come from higher levels due to overconsumption of fluorine.
*Teeth are not supposed to be pure white. The “Hollywood smile” is a lie. Teeth are supposed to be a slightly off-white, ivory color. Anything whiter than that is adding something else that shouldn’t be there, or stripping something off that should be there.
❝How does your diet change clean out your arteries of the bad cholesterol?❞
There’s good news and bad news here, and they can both be delivered with a one-word reply:
Slowly.
Or rather: what’s being cleaned out is mostly not the LDL (bad) cholesterol, but rather, the result of that.
When our diet is bad for cardiovascular health, our arteries get fatty deposits on their walls. Cholesterol gets stuck here too, but that’s not the main physical problem.
Our body’s natural defenses come into action and try to clean it up, but they (for example macrophages, a kind of white blood cell that consumes invaders and then dies, before being recycled by the next part of the system) often get stuck and become part of the buildup (called atheroma), which can lead to atherosclerosis and (if calcium levels are high) hardening of the arteries, which is the worst end of this.
This can then require medical attention, precisely because the body can’t remove it very well—especially if you are still maintaining a heart-unhealthy diet, thus continuing to add to the mess.
However, if it is not too bad yet, yes, a dietary change alone will reverse this process. Without new material being added to the arterial walls, the body’s continual process of rejuvenation will eventually fix it, given time (free from things making it worse) and resources.
In fact, your arteries can be one of the quickest places for your body to make something better or worse, because the blood is the means by which the body moves most things (good or bad) around the body.
All the more reason to take extra care of it, since everything else depends on it!

Mind Gym – by Gary Mack and David Casstevens
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.
While this book seems to be mostly popular amongst young American college athletes and those around them (coaches, parents, etc) its applicability is a lot wider than that.
The thing is, as this book details, we don’t have to settle for less than optimal in our training—whatever “optimal” means for us, at any stage of life.
The style is largely narrative, and conveys a lot of ideas through anecdotes. They are probably true, but whether they occured entirely as-written or have been polished or embellished is not so important, as to to give food for thought, and reflection on how we can hone what we’re doing to work the best for us.
Nor is it just a long pep-talk, though it certainly has a motivational aspect. But rather, it covers also such things as the seven critical areas that we need to excel at if we want to be mentally robust, and—counterintuitively—the value of slowing down sometimes. The authors also talk about the importance of love, labor, and ongoing learning if we want a fulfilled life.
Bottom line: if you are engaged with any sport or sport-like endeavor that you’d like to be better at, this book will sharpen your training and development.

Hypertension: Factors Far More Relevant Than Salt
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.
Hypertension: Factors Far More Relevant Than Salt
Firstly, what is high blood pressure vs normal, and what do those blood pressure readings mean?
Rather than take up undue space here, we’ll just quickly link to…
Blood Pressure Readings Explained (With A Colorful Chart)
More details of specifics, at:
Hypotension | Normal | Elevated | Stage 1 | Stage 2 | Danger zone
Keeping Blood Pressure Down
As with most health-related things (and in fact, much of life in general), prevention is better than cure.
People usually know “limit salt” and “manage stress”, but there’s a lot more to it!
Salt isn’t as big a factor as you probably think
That doesn’t mean go crazy on the salt, as it can cause a lot of other problems, including organ failure. But it does mean that you can’t skip the salt and assume your blood pressure will take care of itself.
This paper, for example, considers “high” sodium consumption to be more than 5g per day, and urinary excretion under 3g per day is considered to represent a low sodium dietary intake:
Sodium Intake and Hypertension
Meanwhile, health organizations often recommend to keep sodium intake to under 2g or under 1.5g
Top tip: if you replace your table salt with “reduced sodium” salt, this is usually sodium chloride (regular table salt) cut with potassium chloride, which is almost as “salty” tastewise, but obviously contains less sodium. Not only that, but potassium actually helps the body eliminate sodium, too.
The rest of what you eat is important too
The Mediterranean Diet is as great for this as it is for most health conditions.
If you sometimes see the DASH diet mentioned, that stands for “Dietary Approaches to Stop Hypertension”, and is basically the Mediterranean Diet with a few tweaks.
What are the tweaks?
- Beans went down a bit in priority
- Red meat got removed entirely instead of “limit to a tiny amount”
- Olive oil was deprioritized, and/but vegetable oil is at the bottom of the list (i.e., use sparingly)
You can check out the details here, with an overview and examples:
DASH Eating Plan—Description, Charts, and Recipes
Don’t drink or smoke
And no, a glass of red a day will not help your heart. Alcohol does make us feel relaxed, but that is because of what it does to our brain, not what it does to our heart.
In reality, even a single drink will increase blood pressure. Yes, really:
And smoking? It’s so bad that even second-hand smoke increases blood pressure:
Get those Zs in
Sleep is a commonly underestimated/forgotten part of health, precisely because in a way, we’re not there for it when it happens. We sleep through it! But it is important, including to protect against hypertension:
Short- and long-term health consequences of sleep disruption
Move your body!
Moving your body often is far more important for your heart than running marathons or bench-pressing your spouse.
Those 150 minutes “moderate exercise” (e.g. walking) per week are important, and can be for example:
- 22 minutes per day, 7 days per week
- 25 minutes per day, 6 days per week
- 30 minutes per day, 5 days per week
- 75 minutes per day, 2 days per week

“You Just Need to Lose Weight” And 19 Other Myths About Fat People – by Aubrey Gordon
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 another book by this author, “What We Don’t Talk About When We Talk About Fat”, and this time, she’s doing some important mythbusting.
The titular “you just need to lose weight” is a commonly-taken easy-out for many doctors, to avoid having to dispense actual treatment for an actual condition. Whether or not weight loss would help in a given situation is often immaterial; “kicking the can down the road” is the goal.
Most of the book is divided into 20 chapters, each of them devoted to debunking one myth. Think of it like 10almonds’ “Mythbusting Friday” edition (indeed, we did one about obesity), but with an entire book, and as much room as she needs to provide much more detail than we can ever get into in a single article.
And far from being a mere polemic, she does indeed provide that detail—this is clearly a very well-researched book, above and beyond the author’s own personal experience. Further, all the key points are illustrated and articulated clearly, making the book’s ideas very comprehensible.
The style is pop-science, but with frequent bibliographical references for relevant sources.
Bottom line: for some readers, this book will come as a great validation; for others, it may be eye-opening. Either way, it’s a very worthwhile read.

Understanding Cellulitis: Skin And Soft Tissue Infections
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.
What’s the difference between a minor passing skin complaint, and a skin condition that’s indicative of something more serious? Dr. Thomas Watchman explains:
More than skin-deep
Cellulitis sounds benign enough, like having a little cellulite perhaps, but in fact it means an infection of the skin and—critically—the underlying soft tissues.
Normally, the skin acts as a barrier against infections, but this barrier can be breached by physical trauma (i.e. an injury that broke the skin), eczema, fungal nail infections, skin ulcers, and other similar things that disrupt the skin’s ability to protect us.
Things to watch out for: Dr. Watchman advises we keep an eye out for warm, reddened skin, swelling, and blisters. Specifically, a golden-yellow crust to these likely indicates a Staphylococcus aureus infection (hence the name).
There’s a scale of degrees of severity:
- Class 1: No systemic toxicity or comorbidities
- Class 2: Systemic toxicity or comorbidities present
- Class 3: Significant systemic toxicity or comorbidities with risk of significant deterioration
- Class 4: Sepsis or life-threatening infection
…with antibiotics being recommended in the latter two cases there, or in other cases for frail, young, old, or immunocompromised patients. Given the rather “scorched earth” results of antibiotics (they cause a lot of collateral iatrogenic damage), this can be taken as a sign of how seriously such infections should be taken.

Keeping Your Kidneys Healthy (Especially After 60)
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.
Keeping your kidneys happy: it’s more than just hydration!
Your kidneys are very busy organs. They filter waste products, balance hydration, pH, salt, and potassium. They also make some of our hormones, and are responsible for regulating red blood cell production too. They also handle vitamin D in a way our bodies would not work without, making them essential for calcium absorption and the health of our bones, and even muscular function.
So, how to keep them in good working order?
Yes, hydrate
This is obvious and may go without saying, but we try to not leave important things without saying. So yes, get plenty of water, spread out over the day (you can only usefully absorb so much at once!). If you feel thirsty, you’re probably already dehydrated, so have a little (hydrating!) drink.
Don’t smoke
It’s bad for everything, including your kidneys.
Look after your blood
Not just “try to keep it inside your body”, but also:
- Keep your blood sugar levels healthy (hyperglycemia can cause kidney damage)
- Keep your blood pressure healthy (hypertension can cause kidney damage)
Basically, your kidneys’ primary job of filtering blood will go much more smoothly if that blood is less problematic on the way in.
Watch your over-the-counter pill intake
A lot of PRN OTC NSAIDs (PRN = pro re nata, i.e. you take them as and when symptoms arise) (NSAIDs = Non-Steroidal Anti-Inflammatory Drugs, such as ibuprofen for example) can cause kidney damage if taken regularly.
Many people take ibuprofen (for example) constantly for chronic pain, especially the kind cause by chronic inflammation, including many autoimmune diseases.
It is recommended to not take them for more than 10 days, nor more than 8 per day. Taking more than that, or taking them for longer, could damage your kidneys temporarily or permanently.

Who’s in a high risk group?
- If you’re over 60
- If you have diabetes
- If you have cardiovascular disease
- If you have high blood pressure
- If you believe, or know, you have existing kidney damage
The tests are very noninvasive, and will be a urine and/or blood test.

5 Golden Rules To Lose Belly Fat
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 belly is often the first place we gain fat and the last to lose it—due to hormonal changes, poor blood flow, and fat cell types. This also means that weight loss efforts can result in it looking worse before it looks better, as we lose weight from elsewhere around it. But, there is a way forwards:
What to do about it
Cori Lefkowith, of “Redefining Strength” and “Strength At Any Age” fame, advise that we follow the following “5 golden rules”:
- Mindset: avoid “All or Nothing” thinking; focus on small, sustainable changes and consistent habits.
- Macros: prioritize protein (40%+ of calories), balance fats and carbs for hormonal health, and avoid extreme calorie deficits (your body will try to save you from starvation by slowing your metabolism to conserve energy, and storing fat).
- Nutrition quality: focus on whole, nutrient-dense foods for better satiety, gut health, and energy. Get plenty of fiber and water; your body still needs those too.
- Muscle building: strength training preserves muscle, boosts metabolism, and improves body composition—don’t ditch your strength training for cardio; it won’t help and that swap would hinder..
- Daily walks: 15–20 minutes of walking after dinner aids digestion, and reduces stress (remember: stress invites your body to store extra fat, especially at the belly). It also incidentally burns calories without stressing the body, but honestly, it’s really not very many calories, so that’s not the main reason to do it.
For more on each of these, enjoy:
