THE CLAIM: Sparkling water is bad for you.
We’ve all heard about the negative health effects of soda. But could bubbly water pose a risk as well? That’s what some internet sites and news reports say, warning that sparkling water does all kinds of bad things to our health. If you enjoy drinking it, though, don’t let these claims burst your bubble.
One of sparkling water’s alleged effects is weight gain.
That’s based mainly on a small study showing that young men who drank carbonated water had increased levels of a hormone called Ghrelin, which increases appetite.
But there’s no evidence that water without added sweeteners actually makes people eat more or gain weight.
In fact, the carbonation may have the opposite effect by making you feel more full.
Then there’s the claim that sparkling water is less hydrating than regular water. That’s false. So is the rumor that it’s bad for your bones. While cola has been linked to lower bone density, sparkling water has not.
Perhaps the most common concern is that it harms teeth.
It’s true that sparkling water has higher acid levels than plain water, and acid can erode tooth enamel.
But sparkling water is less acidic than soda or sports drinks, and any risk is likely small.
To be on the safe side, go easy on waters with added citrus flavors like lemon or lime, which are more acidic.
And drink your bubbly beverage with food, which lowers acid levels.
The carbonation in sparkling water can cause bloating, so if you have certain stomach issues, you may need to steer clear of it and other fizzy drinks. Otherwise, just be sure to read labels and avoid waters with added sugar or other sweeteners. Whether it’s bubbly or flat, water is a good choice – as long as it’s plain.
