Cheeky diet soft drink getting you through the work day? Here’s what that may mean for your health

Many people are drinking less sugary soft drink than in the past. This is a great win for public health, given the recognised risks of diets high in sugar-sweetened drinks.
But over time, intake of diet soft drinks has grown. In fact, it’s so high that these products are now regularly detected in wastewater.
So what does the research say about how your health is affected in the long term if you drink them often?
What makes diet soft drinks sweet?
The World Health Organization (WHO) advises people “reduce their daily intake of free sugars to less than 10% of their total energy intake. A further reduction to below 5% or roughly 25 grams (six teaspoons) per day would provide additional health benefits.”
But most regular soft drinks contain a lot of sugar. A regular 335 millilitre can of original Coca-Cola contains at least seven teaspoons of added sugar.
Diet soft drinks are designed to taste similar to regular soft drinks but without the sugar. Instead of sugar, diet soft drinks contain artificial or natural sweeteners. The artificial sweeteners include aspartame, saccharin and sucralose. The natural sweeteners include stevia and monk fruit extract, which come from plant sources.
Many artificial sweeteners are much sweeter than sugar so less is needed to provide the same burst of sweetness.
Diet soft drinks are marketed as healthier alternatives to regular soft drinks, particularly for people who want to reduce their sugar intake or manage their weight.
But while surveys of Australian adults and adolescents show most people understand the benefits of reducing their sugar intake, they often aren’t as aware about how diet drinks may affect health more broadly.
What does the research say about aspartame?
The artificial sweeteners in soft drinks are considered safe for consumption by food authorities, including in the US and Australia. However, some researchers have raised concern about the long-term risks of consumption.
People who drink diet soft drinks regularly and often are more likely to develop certain metabolic conditions (such as diabetes and heart disease) than those who don’t drink diet soft drinks.
The link was found even after accounting for other dietary and lifestyle factors (such as physical activity).
In 2023, the WHO announced reports had found aspartame – the main sweetener used in diet soft drinks – was “possibly carcinogenic to humans” (carcinogenic means cancer-causing).
Importantly though, the report noted there is not enough current scientific evidence to be truly confident aspartame may increase the risk of cancer and emphasised it’s safe to consume occasionally.
Will diet soft drinks help manage weight?
Despite the word “diet” in the name, diet soft drinks are not strongly linked with weight management.
In 2022, the WHO conducted a systematic review (where researchers look at all available evidence on a topic) on whether the use of artificial sweeteners is beneficial for weight management.
Overall, the randomised controlled trials they looked at suggested slightly more weight loss in people who used artificial sweeteners.
But the observational studies (where no intervention occurs and participants are monitored over time) found people who consume high amounts of artificial sweeteners tended to have an increased risk of higher body mass index and a 76% increased likelihood of having obesity.
In other words, artificial sweeteners may not directly help manage weight over the long term. This resulted in the WHO advising artificial sweeteners should not be used to manage weight.
Studies in animals have suggested consuming high levels of artificial sweeteners can signal to the brain it is being starved of fuel, which can lead to more eating. However, the evidence for this happening in humans is still unproven.
What about inflammation and dental issues?
There is some early evidence artificial sweeteners may irritate the lining of the digestive system, causing inflammation and increasing the likelihood of diarrhoea, constipation, bloating and other symptoms often associated with irritable bowel syndrome. However, this study noted more research is needed.
High amounts of diet soft drinks have also been linked with liver disease, which is based on inflammation.
The consumption of diet soft drinks is also associated with dental erosion.
Many soft drinks contain phosphoric and citric acid, which can damage your tooth enamel and contribute to dental erosion.
Moderation is key
As with many aspects of nutrition, moderation is key with diet soft drinks.
Drinking diet soft drinks occasionally is unlikely to harm your health, but frequent or excessive intake may increase health risks in the longer term.
Plain water, infused water, sparkling water, herbal teas or milks remain the best options for hydration.

It’s Q&A Day!
Each Thursday, we respond to subscriber questions and requests! If it’s something small, we’ll answer it directly; if it’s something bigger, we’ll do a main feature in a follow-up day instead!
So, no question/request to big or small; they’ll just get sorted accordingly
Remember, you can always hit reply to any of our emails, or use the handy feedback widget at the bottom. We always look forward to hearing from you!
Q: Interesting info, however, I drink hazelnut milk LOL so would have liked a review of that. But now I want to give hemp and pea milks a try. Thanks
Aww! Here then just for you, is a quick rundown…
- Pros: high in protein¹, vitamin B, and vitamin E
- Cons: high in fat², low in calcium
¹Compared head-to-head with almond milk for example, it has double the protein (but also double the calories)
²However, is also has been found to lower LDL (bad) cholesterol (and incidentally, also reduce inflammation), and in a later systematic review, it was found to not correlate to weight gain, despite its high calorie-content.
If you don’t already, and would like to try making your own…
Click here for step-by-step instructions to make your own hazelnut milk! (very simple)
Q: Wondering if you can evaluate CLA and using it to assist with weight loss. Thanks
Will do! (Watch this space)
Q: What’s the process behind the books you recommend? You seem to have a limitless stream of recommendations
We do our best!
The books we recommend are books that…
- are on Amazon—it makes things tidy, consistent, and accessible. And if you end up buying one of the books, we get a small affiliate commission*.
- we have read—we would say “obviously”, but you might be surprised how many people write about books without having read them.
- pertain in at least large part to health and/or productivity.
- are written by humans—bookish people (and especially Kindle Unlimited users) may have noticed lately that there are a lot of low quality AI-written books flooding the market, sometimes with paid 5-star reviews to bolster them. It’s frustrating, but we can tell the difference and screen those out.
- are of a certain level of quality. They don’t have to be “top 5 desert-island books”, because well, there’s one every day and the days keep coming. But they do have to genuinely deliver the value that we describe, and merit a sincere recommendation.
- are varied—we try to not give a run of “samey” books one after another. We will sometimes review a book that covers a topic another previously-reviewed book did, but it must have something about it that makes it different. It may be a different angle or a different writing style, but it needs something to set it apart.
*this is from Amazon and isn’t product-specific, so this is not affecting our choice of what books to review at all—just that they will be books that are available on Amazon.
Q: Great video on dopamine. Thumbs up on the book recommendation. Would you please consider doing a piece or two on inflammation? I live with Lupus and it is a constant struggle. Thanks for the awesome work you do. Have an excellent day.
Great suggestion! We will do that, and thank you for the kind words!
Q: Why is your newsletter called 10almonds? Maybe I missed it in the intro email, but my curiosity wants to know the significance. Thanks!”
It’s a reference to a viral Facebook hoax! There was a post going around that claimed:
❝HEADACHE REMEDY. Eat 10–12 almonds, the equivalent of two aspirins, next time you have a headache❞ ← not true!
It made us think about how much health-related disinformation there was online… So, calling ourselves 10almonds was a bit of a tongue-in-cheek reference to that story… but also a reminder to ourselves:
We must always publish information with good scientific evidence behind it!

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
❝How long do I have to soak oats for to get the benefits of “overnight oats”?❞
The primary benefit of overnight oats (over cooked oats) is that they are soft enough to eat without having been cooked (as cooking increases their glycemic index).
So, if it’s soft, it’s good to eat. A few hours should be sufficient.
Bonus information
If, by the way, you happen to leave oats and milk (be it animal or plant milk) sealed in a jar at room temperature for a 2–3 days (less if your “room temperature” is warmer than average), it will start to ferment.
- Good news: fermentation can bring extra health benefits!
- Bad news: you’re on your own if something pathogenic is present

Beating Sleep Apnea

Healthier, Natural Sleep Without Obstruction!
Obstructive Sleep Apnea, the sleep disorder in which one periodically stops breathing (and thus wakes up) repeatedly through the night, affects about 25% of men and 10% of women:
Prevalence of Obstructive Sleep Apnea Syndrome: A Single-Center Retrospective Study
Why the gender split?
There are clues that suggest it is at least partially hormonal: once women have passed menopause, the gender split becomes equal.
Are there other risk factors?
There are few risk other factors; some we can’t control, and some we can:
- Being older is riskier than being younger
- Being overweight is riskier than not being overweight
- Smoking is (what a shock) riskier than not smoking
- Chronic respiratory diseases increase risk, for example:
- Asthma
- COPD
- Long COVID*—probably. The science is young for this one so far, so we can’t say for sure until more research has been done.
- Some hormonal conditions increase risk, for example:
- Hypothyroidism
- PCOS
*However, patients already undergoing Continuous Positive Airway Pressure (CPAP) treatment for obstructive sleep apnea may have an advantage when fighting a COVID infection:
What can we do about it?
Avoiding the above risk factors, where possible, is great!
If you are already suffering from obstructive sleep apnea, then you probably already know about the possibility of a CPAP device; it’s a mask that one wears to sleep, and it does what its name says (i.e. it applies continuous positive airway pressure), which keeps the airway open.
We haven’t tested these, but other people have, so here are some that the Sleep Foundation found to be worthy of note:
Sleep Foundation | Best CPAP Machines of 2024
What can we do about it that’s not CPAP?
Wearing a mask to sleep is not everyone’s preferred way to do things. There are also a plethora of surgeries available, but we’ll not review those, as those are best discussed with your doctor if necessary.
However, some lifestyle changes can help, including:
- Lose weight, if overweight. In particular, having a collar size under 16” for women or under 17” for men, is sufficient to significantly reduce the risk of obstructive sleep apnea.
- Stop smoking, if you smoke. This one, we hope, is self-explanatory.
- Stop drinking alcohol, or at least reduce intake, if you drink. People who consume alcohol tend to have more frequent, and longer, incidents of obstructive sleep apnea. See also: How To Reduce Or Quit Drinking
- Avoid sedatives and muscle relaxants, if it is safe for you to do so. Obviously, if you need them to treat some other condition you have, talk this through with your doctor. But basically, they can contribute to the “airway collapses on itself” by reducing the muscular tension that keeps your airway the shape it’s supposed to be.
- Sleep on your side, not your back. This is just plain physics, and a matter of wear the obstruction falls.
- Breathe through your nose, not through your mouth. Initially tricky to do while sleeping, but the more you practice it while awake, the more it becomes possible while asleep.
- Consider a nasal decongestant before sleep, if congestion is a problem for you, as that can help too.

We live in an information-saturated world, and we have done for so long now that it’s easy to forget: we did not evolve for this!
It’s easy to say “unplug”, but the reality is:
We also have to actually function in this fast-paced info-dense world whether we want to or not, and we are expected to be able to handle it.
So… How?
Appropriately enough, authors Knapp and Zeratsky present the answer in a skimmer-friendly fashion, with summaries and bullet points and diagrams and emboldened text forease of speed-reading. Who uses such tricks?!
In short, less living life in “default mode scramble” and more about making an impact in the ways you actually want to, for you.

The Problem With Sweeteners

The WHO’s new view on sugar-free sweeteners
The WHO has released a report offering guidance regards the use of sugar-free sweeteners as part of a weight-loss effort.
In a nutshell, the guidance is: don’t
- Here’s the report itself: Use of non-sugar sweeteners: WHO guideline
- Here’s the WHO’s own press release about it: WHO advises not to use non-sugar sweeteners for weight control in newly released guideline
- And it was based on this huge systematic review: Health effects of the use of non-sugar sweeteners: a systematic review and meta-analysis
They make for interesting reading, so if you don’t have time now, you might want to just quickly open and bookmark them for later!
Some salient bits and pieces:
Besides that some sweeteners can cause gastro-intestinal problems, a big problem is desensitization:
Because many sugar substitutes are many times (in some cases, hundreds of times) sweeter than sugar, this leads to other sweet foods tasting more bland, causing people to crave sweeter and sweeter foods for the same satisfaction level.
You can imagine how that’s not a spiral that’s good for the health!
The WHO recommendation applies to artificial and naturally-occurring non-sugar sweeteners, including:
- Acesulfame K
- Advantame
- Aspartame
- Cyclamates
- Neotame
- Saccharin
- Stevia
Sucralose and erythritol, by the way, technically are sugars, just not “that kind of sugar” so they didn’t make the list of non-sugar sweeteners.
That said, a recent study did find that erythritol was linked to a higher risk of heart attack, stroke, and early death, so it may not be an amazing sweetener either:

Want to know a good way of staying healthy in the context of sweeteners?
Just get used to using less. Your taste buds will adapt, and you’ll get just as much pleasure as before, from progressively less sweetening agent.

It’s Not You, It’s Your Hormones – by Nicki Williams, DipION, mBANT, CNHC
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.
So, first a quick note: this book is very similar to the popular bestseller “The Galveston Diet”, not just in content, but all the way down to its formatting. Some Amazon reviewers have even gone so far as to suggest that “It’s Not You, It’s Your Hormones” (2017) brazenly plagiarized “The Galveston Diet” (2023). However, after carefully examining the publication dates, we feel quite confident that this book is not a copy of the one that came out six years after it. As such, we’ve opted for reviewing the original book.
Nicki Williams’ basic principle is that we can manage our hormonal fluctuations, by managing our diet. Specifically, in three main ways:
- Intermittent fasting
- Anti-inflammatory diet
- Eating more protein and healthy fats
Why should these things matter to our hormones? The answer is to remember that our hormones aren’t just the sex hormones. We have hormones for hunger and satedness, hormones for stress and relaxation, hormones for blood sugar regulation, hormones for sleep and wakefulness, and more. These many hormones make up our endocrine system, and affecting one part of it will affect the others.
Will these things magically undo the effects of the menopause? Well, some things yes, other things no. No diet can do the job of HRT. But by tweaking endocrine system inputs, we can tweak endocrine system outputs, and that’s what this book is for.
The style is very accessible and clear, and Williams walks us through the changes we may want to make, to avoid the changes we don’t want.
Bottom line: this book is aimed at peri-menopausal and post-menopausal women. It could also definitely help a lot of people with PCOS too, and, when it comes down it it, pretty much anyone with an endocrine system. It’s a well-evidenced, well-established, healthy way of eating regardless of age, sex, or (most) physical conditions.
