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.

Thai-Style Kale Chips
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.
…that are actually crispy, tasty, and packed with nutrients! Lots of magnesium and calcium, and array of health-giving spices too.
You will need
- 7 oz raw curly kale, stalks removed
- extra virgin olive oil, for drizzling
- 3 cloves garlic, crushed
- 2 tsp red chili flakes (or crushed dried red chilis)
- 2 tsp light soy sauce
- 2 tsp water
- 1 tbsp crunchy peanut butter (pick one with no added sugar, salt, etc)
- 1 tsp honey
- 1 tsp Thai seven-spice powder
- 1 tsp black pepper
- 1 tsp MSG or 1 tsp low-sodium salt
Method
(we suggest you read everything at least once before doing anything)
1) Pre-heat the oven to 180℃ / 350℉ / Gas mark 4.
2) Put the kale in a bowl and drizzle a little olive oil over it. Work the oil in gently with your fingertips so that the kale is coated; the leaves will also soften while you do this; that’s expected, so don’t worry.
3) Mix the rest of the ingredients to make a sauce; coat the kale leaves with the sauce.
4) Place on a baking tray, as spread-out as there’s room for, and bake on a middle shelf for 15–20 minutes. If your oven has a fierce heat source at the top, it can be good to place an empty baking tray on a shelf above the kale chips, to baffle the heat and prevent them from cooking unevenly—especially if it’s not a fan oven.
5) Remove and let cool, and then serve! They can also be stored in an airtight container if desired.
Enjoy!

A drug that can extend your life by 25%? Don’t hold your breath
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.
Every few weeks or months, the media reports on a new study that tantalisingly dangles the possibility of a new drug to give us longer, healthier lives.
The latest study centres around a drug involved in targeting interleukin-11, a protein involved in inflammation. Blocking this protein appeared to help mice stave off disease and extend their life by more than 20%.
If only defying the ravages of time could be achieved through such a simple and effort-free way – by taking a pill. But as is so often the case, the real-world significance of these findings falls a fair way short of the hype.
Halfpoint/Shutterstock The role of inflammation in disease and ageing
Chronic inflammation in the body plays a role in causing disease and accelerating ageing. In fact, a relatively new label has been coined to represent this: “inflammaging”.
While acute inflammation is an important response to infection or injury, if inflammation persists in the body, it can be very damaging.
A number of lifestyle, environmental and societal drivers contribute to chronic inflammation in the modern world. These are largely the factors we already know are associated with disease and ageing, including poor diet, lack of exercise, obesity, stress, lack of sleep, lack of social connection and pollution.
While addressing these issues directly is one of the keys to addressing chronic inflammation, disease and ageing, there are a number of research groups also exploring how to treat chronic inflammation with pharmaceuticals. Their goal is to target and modify the molecular and chemical pathways involved in the inflammatory process itself.
What the latest research shows
This new interleukin-11 research was conducted in mice and involved a number of separate components.
In one component of this research, interleukin-11 was genetically knocked out in mice. This means the gene for this chemical mediator was removed from these mice, resulting in the mice no longer being able to produce this mediator at all.
In this part of the study, the mice’s lives were extended by over 20%, on average.
Another component of this research involved treating older mice with a drug that blocks interleukin-11.
Injecting this drug into 75-week old mice (equivalent to 55-year-old humans) was found to extend the life of mice by 22-25%.
These treated mice were less likely to get cancer and had lower cholesterol levels, lower body weight and improved muscle strength and metabolism.
From these combined results, the authors concluded, quite reasonably, that blocking interleukin-11 may potentially be a key to mitigating age-related health effects and improving lifespan in both mice and humans.
Why you shouldn’t be getting excited just yet
There are several reasons to be cautious of these findings.
First and most importantly, this was a study in mice. It may be stating the obvious, but mice are very different to humans. As such, this finding in a mouse model is a long way down the evidence hierarchy in terms of its weight.
Research shows only about 5% of promising findings in animals carry over to humans. Put another way, approximately 95% of promising findings in animals may not be translated to specific therapies for humans.
Second, this is only one study. Ideally, we would be looking to have these findings confirmed by other researchers before even considering moving on to the next stage in the knowledge discovery process and examining whether these findings may be true for humans.
We generally require a larger body of evidence before we get too excited about any new research findings and even consider the possibility of human trials.
Third, even if everything remains positive and follow-up studies support the findings of this current study, it can take decades for a new finding like this to be translated to successful therapies in humans.
Until then, we can focus on doing the things we already know make a huge difference to health and longevity: eating well, exercising, maintaining a healthy weight, reducing stress and nurturing social relationships.

Guava vs Pineapple – 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 guava to pineapple, we picked the guava.
Why?
Pineapple is great, but guava just beats it in most ways:
In terms of macros, guava has nearly 4x the fiber and nearly 5x the protein, for the same carbs, giving it the notably lower glycemic index. An easy win for guava in this category.
In the category of vitamins, guava has a lot more of vitamins A, B2, B3, B5, B9, C, E, K, and choline, while pineapple has marginally more vitamin B1. Another clear win for guava.
When it comes to minerals, guava has more calcium, copper, magnesium, phosphorus, potassium, selenium, and zinc, while pineapple has more iron and manganese. One more win for guava.
One big thing in pineapple’s favor is that it contains bromelain, which is an enzyme* found in pineapple (and only in pineapple), that has many very healthful properties, some of them unique to bromelain (and thus: unique to pineapple)
*actually a combination of enzymes, but most often referred to collectively in the singular. But when you do see it referred to as “they”, that’s what that means.
However cool that is, we think it unfair to weight it against guava winning in every other category, so we still say guava gets the overall win.
Of course, enjoy either or both; diversity is good!

Oral vaccines could provide relief for people who suffer regular UTIs. Here’s how they work
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.
In a recent TikTok video, Australian media personality Abbie Chatfield shared she was starting a vaccine to protect against urinary tract infections (UTIs).
Huge news for the UTI girlies. I am starting a UTI vaccine tonight for the first time.
Chatfield suffers from recurrent UTIs and has turned to the Uromune vaccine, an emerging option for those seeking relief beyond antibiotics.
But Uromune is not a traditional vaccine injected to your arm. So what is it and how does it work?
9nong/Shutterstock First, what are UTIs?
UTIs are caused by bacteria entering the urinary system. This system includes the kidneys, bladder, ureters (thin tubes connecting the kidneys to the bladder), and the urethra (the tube through which urine leaves the body).
The most common culprit is Escherichia coli (E. coli), a type of bacteria normally found in the intestines.
While most types of E. coli are harmless in the gut, it can cause infection if it enters the urinary tract. UTIs are particularly prevalent in women due to their shorter urethras, which make it easier for bacteria to reach the bladder.
Roughly 50% of women will experience at least one UTI in their lifetime, and up to half of those will have a recurrence within six months.
UTIs are caused by bacteria enterning the urinary system. oxo7051/Shutterstock The symptoms of a UTI typically include a burning sensation when you wee, frequent urges to go even when the bladder is empty, cloudy or strong-smelling urine, and pain or discomfort in the lower abdomen or back. If left untreated, a UTI can escalate into a kidney infection, which can require more intensive treatment.
While antibiotics are the go-to treatment for UTIs, the rise of antibiotic resistance and the fact many people experience frequent reinfections has sparked more interest in preventive options, including vaccines.
What is Uromune?
Uromune is a bit different to traditional vaccines that are injected into the muscle. It’s a sublingual spray, which means you spray it under your tongue. Uromune is generally used daily for three months.
It contains inactivated forms of four bacteria that are responsible for most UTIs, including E. coli. By introducing these bacteria in a controlled way, it helps your immune system learn to recognise and fight them off before they cause an infection. It can be classified as an immunotherapy.
A recent study involving 1,104 women found the Uromune vaccine was 91.7% effective at reducing recurrent UTIs after three months, with effectiveness dropping to 57.6% after 12 months.
These results suggest Uromune could provide significant (though time-limited) relief for women dealing with frequent UTIs, however peer-reviewed research remains limited.
Any side effects of Uromune are usually mild and may include dry mouth, slight stomach discomfort, and nausea. These side effects typically go away on their own and very few people stop treatment because of them. In rare cases, some people may experience an allergic reaction.
How can I access it?
In Australia, Uromune has not received full approval from the Therapeutic Goods Administration (TGA), and so it’s not something you can just go and pick up from the pharmacy.
However, Uromune can be accessed via the TGA’s Special Access Scheme or the Authorised Prescriber pathway. This means a GP or specialist can apply for approval to prescribe Uromune for patients with recurrent UTIs. Once the patient has a form from their doctor documenting this approval, they can order the vaccine directly from the manufacturer.
Antibiotics are the go-to treatment for UTIs – but scientists are looking at options to prevent them in the first place. Photoroyalty/Shutterstock Uromune is not covered under the Pharmaceutical Benefits Scheme, meaning patients must cover the full cost out-of-pocket. The cost of a treatment program is around A$320.
Uromune is similarly available through special access programs in places like the United Kingdom and Europe.
Other options in the pipeline
In addition to Uromune, scientists are exploring other promising UTI vaccines.
Uro-Vaxom is an established immunomodulator, a substance that helps regulate or modify the immune system’s response to bacteria. It’s derived from E. coli proteins and has shown success in reducing UTI recurrences in several studies. Uro-Vaxom is typically prescribed as a daily oral capsule taken for 90 days.
FimCH, another vaccine in development, targets something called the adhesin protein that helps E. coli attach to urinary tract cells. FimCH is typically administered through an injection and early clinical trials have shown promising results.
Meanwhile, StroVac, which is already approved in Germany, contains inactivated strains of bacteria such as E. coli and provides protection for up to 12 months, requiring a booster dose after that. This injection works by stimulating the immune system in the bladder, offering temporary protection against recurrent infections.
These vaccines show promise, but challenges like achieving long-term immunity remain. Research is ongoing to improve these options.
No magic bullet, but there’s reason for optimism
While vaccines such as Uromune may not be an accessible or perfect solution for everyone, they offer real hope for people tired of recurring UTIs and endless rounds of antibiotics.
Although the road to long-term relief might still be a bit bumpy, it’s exciting to see innovative treatments like these giving people more options to take control of their health.

Eat To Avoid (Or Beat) PCOS
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.
Polycystic ovary syndrome, PCOS, affects very many people; around 1 in 5 women. It can show up unexpectedly, and usually the first-identified sign is irregular vaginal bleeding. We say “vaginal” rather than “menstrual” as it’s not technically menses, although it’ll look (and can feel) the same.
Like many “affects mostly women” conditions, science’s general position is “we don’t know what causes it or how to cure it”.
Quick book recommendation before we continue:
Unwell Women: Misdiagnosis and Myth in a Man-Made World – by Dr. Elinor Cleghorn
…is a top-tier book about medical misogyny. We’d say more here, but well, you can read our review there 🙂
What doesn’t work
Since PCOS is characterized by excessive androgen production, it is reasonable to expect that foods containing phytoestrogens (such as soy) may help. They won’t. The human body can’t use those as estrogen, and in fact, consuming unusually large quantities of phytoestrogens can actually get in the way of your own (or bioidentical) estrogen, by competing for the same receptors but not really doing the job.
But, you won’t get that problem from moderate consumption of soy; the warning is more for those tempted to self-medicate with megadoses, or are opting for dubious supplements such as Pueraria mirifica ← will have to do a research review on that one of these days, but suffice it to say meanwhile, it has some serious drawbacks
See also: What Does “Balance Your Hormones” Even Mean?
What can work
There are some supplement-based approaches that actually can help, and those are the ones that rather than trying to manufacture estrogen out of thin air, work to reduce testosterone and/or reduce the conversion of free testosterone to its more potent form, dihydrogen testosterone (DHT); here are two examples:
- Licorice, Digestion, & Hormones
- One Man’s Saw Palmetto Is Another Woman’s Serenoa Repens ← this one has the most evidence of the two
What will work
…or at least, barring additional confounding factors, what the evidence strongly supports working. Here’s where we get into diet properly, and there are three main dietary approaches:
Low-GI diet: focus on high-fiber, low-carb foods (e.g. whole grains, legumes, berries, leafy greens). Eating this way results in improved insulin sensitivity, lower fasting insulin, cholesterol, triglycerides, waist circumference, and (for women) yes, lower testosterone levels.
See: What Do The Different Kinds Of Fiber Do? 30 Foods That Rank Highest
High antioxidant diet: focus on foods rich in antioxidants (e.g. vitamin A, α-tocopherol specifically, vitamins C and D, and polyphenols) as these lower PCOS incidence.
See: 21 Most Beneficial Polyphenols & What Foods Have Them
Ketogenic diet: focus on high-fat, very low-carb foods (e.g. fatty fish, dairy, leafy greens). This significantly reduces androgen levels, improves insulin sensitivity, and regulates hormones. But… It’s recommended for short-term use only due to its negative health impacts from poor (i.e. narrow) nutritional coverage:
See: Ketogenic Diet: Burning Fat, Or Burning Out?
It is also reasonable to supplement, for example:
❝Omega-3 fatty acids and vitamin D have powerful anti-inflammatory and antioxidant properties that significantly improve insulin sensitivity and reduce androgen levels in metabolic syndromes like PCOS. A higher intake of omega-3 and vitamin E also alleviates mental health parameters and gene expression of PPAR-γ, IL-8, and TNF-α in women with PCOS.
Dietary supplements, such as antioxidants like N-acetylcysteine (NAC), vitamin D, inositol, and omega-3 fatty acids, and mineral supplements (zinc, magnesium selenium, and chromium) help in reducing insulin resistance. These supplements also enhance ovulatory function and decrease inflammation in PCOS patients.
Omega-3 fatty acid supplements improve biochemical parameters LH, LH/FSH, lipid profiles, and adiponectin levels and regularize the menstrual cycle in women with PCOS. A recent RCT also indicated that probiotic/symbiotic supplementation significantly improves triglyceride, insulin, and HDL levels in women with PCOS.❞

Spark – by Dr. John Ratey
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 all know that exercise is good for mental health as well as physical. So, what’s so revolutionary about this “revolutionary new science of exercise and the brain”?
A lot of it has to do with the specific neuroscience of how exercise has not only a mood-boosting effect (endorphins) and neuroprotective effect (helping to guard against cognitive decline), but also promotes neuroplasticity… e.g., the creation and strengthening of neural pathways, as well as boosting the structure of the brain in some parts such as the cerebellum.
The book also covers not just “exercise has these benefits”, but also the “how this works” of all kinds of brain benefits, including:
- against Alzheimer’s
- mitigating ADHD
- managing menopause
- dealing with addiction
…and more. And once we understand how something works, we’re far more likely to be motivated to actually do the kinds of exercises that give the specific benefits we want/need. Which is very much the important part!
In short: this book will tell you what you need to know to get you doing the exercises you need to enjoy those benefits—very much worth it!
