Do you prefer sparkling or still water? When we hear this question at a café or restaurant, we usually make our choice with confidence. But is that choice linked to our health? And do we really understand the pros and cons of carbonated versus non-carbonated water?
Researchers from Bond University in Australia—Christian Moro, an associate professor in the School of Natural Sciences, and Charlotte Phelps, a senior research fellow—shed light on these and other aspects of water consumption.
By the way, the bubbles in sparkling water are created by adding carbon dioxide to filtered water. This reaction produces carbonic acid, making sparkling water more acidic (with a pH around 3.5) compared to still water (which has a pH of about 6.5 to 8.5).
Which Water is the Healthiest?
Water is the best way to hydrate our bodies. Studies have shown that when it comes to hydration, both still and sparkling water are equally effective. Plus, both types of water are always a better choice than any artificially sweetened flavored drinks.
Some people believe that bottled water is healthier. However, in some countries (like Australia), tap water is rigorously monitored. Unlike bottled water, it has the added benefit of fluoride, which helps protect both children and adults from cavities.
Isn’t Sparkling Water Bad for Teeth and Bones?
There is no evidence that sparkling water harms our bones. While it is known that consuming large amounts of sugary soft drinks is associated with an increased risk of fractures.
Sparkling water is more acidic than still water, and acid can soften tooth enamel. However, this is usually not a major concern unless it is mixed with sugar or citrus, which have significant acidity levels and can damage teeth.
In most cases, it would take a very large amount of sparkling water consumed over a long period to cause noticeable harm to teeth.
How Does Drinking Water Affect Digestion?
There is a common misconception that drinking water (any kind) during meals negatively impacts digestion. Although theoretically, water can dilute stomach acid that breaks down food, its consumption has no adverse effects. Our digestive system simply adapts to the consistency of the food.
Some believe that carbonated drinks cause stomach upset. This can happen due to gas buildup, which may lead to bloating, cramps, and discomfort. For individuals with an overactive bladder, the acid may also worsen urinary system function, as reported by Science Alert.
Is Cold Water Really Harder to Digest?
You’ve chosen still or sparkling water. But what about its temperature? Surprisingly, there is very little research on the effects of cold water on the human body. Some evidence suggests that cool water can suppress stomach contractions and slow digestion, while ice-cold water may constrict blood vessels and cause cramps.
However, other studies indicate that drinking cold water can 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.
So, Which Water Comes Out on Top?
The bottom line is that water offers numerous health benefits. Whether sparkling or still, it will always be the healthiest beverage.
If you’re concerned about the potential impact of sparkling water on tooth enamel, there’s a simple trick. After drinking sparkling water, you can have a bit of still water or rinse your mouth with it. This will help restore the acidity levels in your mouth.
