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

Is still water better for you than sparkling water?
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.
Still or sparkling? It’s a question you’ll commonly hear in a café or restaurant and you probably have a preference. But is there any difference for your health?
If you love the fizz, here’s why you don’t have to pass on the sparkling water.
What makes my water sparkle?
This article specifically focuses on comparing still filtered water to carbonated filtered water (called “sparkling water” or “unflavoured seltzer”). Soda water, mineral water, tonic water and flavoured water are similar, but not the same product.
The bubbles in sparkling water are created by adding carbon dioxide to filtered water. It reacts to produce carbonic acid, which makes sparkling water more acidic (a pH of about 3.5) than still (closer to neutral, with a pH around 6.5-8.5).
Which drink is healthiest?
Water is the best way to hydrate our bodies. Research shows when it comes to hydration, still and sparkling water are equally effective.
Some people believe water is healthier when it comes from a sealed bottle. But in Australia, tap water is monitored very carefully. Unlike bottled water, it also has the added benefit of fluoride, which can help protect young children against tooth decay and cavities.
Sparkling or still water is always better than artificially sweetened flavoured drinks or juices.
Isn’t soda water bad for my teeth and bones?
There’s no evidence sparkling water damages your bones. While drinking a lot of soft drinks is linked to increased fractures, this is largely due to their association with higher rates of obesity.
Sparkling water is more acidic than still water, and acidity can soften the teeth’s enamel. Usually this is not something to be too worried about, unless it is mixed with sugar or citrus, which has much higher levels of acidity and can harm teeth.
However, if you grind your teeth often, the softening could enhance the damage it causes. If you’re undertaking a home whitening process, sparkling water might discolour your teeth.
In most other cases, it would take a lot of sparkling water to pass by the teeth, for a long period of time, to cause any noticeable damage.
How does drinking water affect digestion?
There is a misconception drinking water (of any kind) with a meal is bad for digestion.
While theoretically water could dilute stomach acid (which breaks down food), the practice of drinking it doesn’t appear to have any negative effect. Your digestive system simply adapts to the consistency of the meal.
Some people do find that carbonated beverages cause some stomach upset. This is due to the build-up of gases, which can cause bloating, cramping and discomfort. For people with an overactive bladder, the acidity might also aggravate the urinary system.
Interestingly, the fizzy “buzz” you feel in your mouth from sparkling water fades the more you drink it.
Is cold water harder to digest?
You’ve chosen still or sparkling water. What about its temperature?
There are surprisingly few studies about the effect of drinking cold water compared to room temperature. There is some evidence colder water (at two degrees Celsius) might inhibit gastric contractions and slow down digestion. Ice water may constrict blood vessels and cause cramping.
However other research suggests drinking cold water might temporarily boost metabolism, as the body needs to expend energy to warm it up to body temperature. This effect is minimal and unlikely to lead to significant weight loss.
Which water wins?
The bottom line is water is essential, hydrates us and has countless other health benefits. Water, with carbonated bubbles or without, will always be the healthiest drink to choose.
And if you’re concerned about any impact to teeth enamel, one trick is to follow sparkling water with a glass of still. This helps rinse the teeth and return your mouth’s acidity back to normal.

The Comfort Book – by Matt Haig
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 book “is what it says on the tin”. Matt Haig, bestselling author of “Reasons to Stay Alive” (amongst other works) is here with “a hug in a book”.
The format of the book is an “open it at any page and you’ll find something of value” book. Its small chapters are sometimes a few pages long, but often just a page. Sometimes just a line. Always deep.
All of us, who live long enough, will ponder our mortality sometimes. The feelings we may have might vary on a range from “afraid of dying” to “despairing of living”… but Haig’s single biggest message is that life is full of wonder; each moment precious.
- That hope is an incredible (and renewable!) resource.
- That we are more than a bad week, or month, or year, or decade.
- That when things are taken from us, the things that remain have more value.
Bottom line: you might cry (this reviewer did!), but it’ll make your life the richer for it, and remind you—if ever you need it—the value of your amazing life.

The Liver Cure – by Dr. Russell Blaylock
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 written before about How To Unfatty A Fatty Liver, but there’s a lot more that can be said in a book that we couldn’t fit into our article.
In this book, Dr. Blaylock looks at the causes and symptoms of liver disease, the mechanisms behind such, and how we can adjust our dietary habits (and other things) to do better for ourselves.
While the book’s primary focus is on diet, he does also look at medications (especially: those that hinder liver health, which are many, including simple/common stuff like Tylenol and similar), and the effects of different lifestyle choices, including ones that aren’t diet-related.
Because most people’s knowledge of liver disease starts and ends at “don’t drink yourself to death”, this book is an important tome of knowledge for actually keeping this critical organ in good order—especially since symptoms of liver disease can initially be subtle, and slow to show, often escaping notice until it’s already far, far worse than it could have been.
Many people find out by experiencing liver failure.
The writing style is… A little repetitive for this reviewer’s preference, but it does make sure that you won’t miss things. Also, when it comes to supplements, he repeatedly recommends a particular company, and it’s not clear whether he has a financial interest there. But the actual medical information is good and important and comprehensive.
Bottom line: if you’d like to keep your liver in good health, this is a book that will help you to do just that.

Watermelon vs Cucumber – 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 watermelon to cucumber, we picked the cucumber.
Why?
Both are good! But in the battle of the “this is mostly water” salad items, cucumber wins out.
In terms of macros they both are, as we say, mostly water. However, watermelon contains more sugar for the same amount of fiber, contributing to cucumber having the lower glycemic index.
When it comes to vitamins, watermelon does a little better; watermelon has more of vitamins A, B1, B3, B6, C, and E, while cucumber has more of vitamins B2, B5, B9, K, and choline. So, a modest 6:5 win for watermelon.
In the category of minerals, it’s a different story; watermelon has more selenium, while cucumber has more calcium, iron, magnesium, manganese, phosphorus, potassium, and zinc.
Both contain an array of polyphenols; mostly different ones from each other.
As ever, enjoy both. However, adding up the sections, we say cucumber enjoys a marginal win here.

What’s the difference between Alzheimer’s and dementia?
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? is a new editorial product that explains the similarities and differences between commonly confused health and medical terms, and why they matter.
Changes in thinking and memory as we age can occur for a variety of reasons. These changes are not always cause for concern. But when they begin to disrupt daily life, it could indicate the first signs of dementia.
Another term that can crop up when we’re talking about dementia is Alzheimer’s disease, or Alzheimer’s for short.
So what’s the difference?
What is dementia?
Dementia is an umbrella term used to describe a range of syndromes that result in changes in memory, thinking and/or behaviour due to degeneration in the brain.
To meet the criteria for dementia these changes must be sufficiently pronounced to interfere with usual activities and are present in at least two different aspects of thinking or memory.
For example, someone might have trouble remembering to pay bills and become lost in previously familiar areas.
It’s less-well known that dementia can also occur in children. This is due to progressive brain damage associated with more than 100 rare genetic disorders. This can result in similar cognitive changes as we see in adults.
So what’s Alzheimer’s then?
Alzheimer’s is the most common type of dementia, accounting for about 60-80% of cases.
So it’s not surprising many people use the terms dementia and Alzheimer’s interchangeably.
Changes in memory are the most common sign of Alzheimer’s and it’s what the public most often associates with it. For instance, someone with Alzheimer’s may have trouble recalling recent events or keeping track of what day or month it is.
We still don’t know exactly what causes Alzheimer’s. However, we do know it is associated with a build-up in the brain of two types of protein called amyloid-β and tau.
While we all have some amyloid-β, when too much builds up in the brain it clumps together, forming plaques in the spaces between cells. These plaques cause damage (inflammation) to surrounding brain cells and leads to disruption in tau. Tau forms part of the structure of brain cells but in Alzheimer’s tau proteins become “tangled”. This is toxic to the cells, causing them to die. A feedback loop is then thought to occur, triggering production of more amyloid-β and more abnormal tau, perpetuating damage to brain cells.
Alzheimer’s can also occur with other forms of dementia, such as vascular dementia. This combination is the most common example of a mixed dementia.
Vascular dementia
The second most common type of dementia is vascular dementia. This results from disrupted blood flow to the brain.
Because the changes in blood flow can occur throughout the brain, signs of vascular dementia can be more varied than the memory changes typically seen in Alzheimer’s.
For example, vascular dementia may present as general confusion, slowed thinking, or difficulty organising thoughts and actions.
Your risk of vascular dementia is greater if you have heart disease or high blood pressure.
Frontotemporal dementia
Some people may not realise that dementia can also affect behaviour and/or language. We see this in different forms of frontotemporal dementia.
The behavioural variant of frontotemporal dementia is the second most common form (after Alzheimer’s disease) of younger onset dementia (dementia in people under 65).
People living with this may have difficulties in interpreting and appropriately responding to social situations. For example, they may make uncharacteristically rude or offensive comments or invade people’s personal space.
Semantic dementia is also a type of frontotemporal dementia and results in difficulty with understanding the meaning of words and naming everyday objects.
Dementia with Lewy bodies
Dementia with Lewy bodies results from dysregulation of a different type of protein known as α-synuclein. We often see this in people with Parkinson’s disease.
So people with this type of dementia may have altered movement, such as a stooped posture, shuffling walk, and changes in handwriting. Other symptoms include changes in alertness, visual hallucinations and significant disruption to sleep.
Do I have dementia and if so, which type?
If you or someone close to you is concerned, the first thing to do is to speak to your GP. They will likely ask you some questions about your medical history and what changes you have noticed.
Sometimes it might not be clear if you have dementia when you first speak to your doctor. They may suggest you watch for changes or they may refer you to a specialist for further tests.
There is no single test to clearly show if you have dementia, or the type of dementia. A diagnosis comes after multiple tests, including brain scans, tests of memory and thinking, and consideration of how these changes impact your daily life.
Not knowing what is happening can be a challenging time so it is important to speak to someone about how you are feeling or to reach out to support services.
Dementia is diverse
As well as the different forms of dementia, everyone experiences dementia in different ways. For example, the speed dementia progresses varies a lot from person to person. Some people will continue to live well with dementia for some time while others may decline more quickly.
There is still significant stigma surrounding dementia. So by learning more about the various types of dementia and understanding differences in how dementia progresses we can all do our part to create a more dementia-friendly community.
The National Dementia Helpline (1800 100 500) provides information and support for people living with dementia and their carers. To learn more about dementia, you can take this free online course.

The Best Menopause Advice You Don’t Want To Hear About
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.
Nutritionist and perimenopause coach Claudia Canu, whom we’ve featured before in our Expert Insights segment, has advice:
Here’s to good health
When it comes to alcohol, the advice is: don’t.
Or at least, cut back, and manage the effects by ensuring good hydration, having an “alcohol curfew” and so forth.
What’s the relation to menopause? Well, alcohol’s not good for anyone at any time of life, but there are some special considerations when it comes to alcohol and estrogenic hormonal health:
- The liver works hard to process the alcohol as a matter of urgency, delaying estrogen processing, which can increase the risk of breast and uterine cancer.
- Alcohol has no positive health effects and is also linked to higher risks of breast and colorectal cancer.
- Alcohol can also trigger some menopausal symptoms, such as night sweats and hot flashes. So, maybe reaching for that “cooling drink” isn’t the remedy it might seem.
- During menopause, the body becomes more insulin-resistant, making it more susceptible to blood sugar spikes caused by alcohol. Also not good.
Common reasons women turn to alcohol include stress, frustration, the need for reward, and social pressure, and all of these can be heightened when undergoing hormonal changes. Yet, alcohol will ultimately only worsen each of those things.
