Carbonated Water Not Always A Healthy Alternative

BOSTON (CBS) - Many people drink carbonated water, thinking it's a healthier option than soda or sugary drinks, but as Dr. Mallika Marshall reports, it may not be.

Sales of carbonated water in the United States have doubled over the past five years. But not all fizzy water is the same. Despina Hyde is a registered dietitian at NYU Langone. She says it's important to read the labels.

"The best bet is to choose something without any sweeteners at all," says Hyde.

She says sweeteners are often found in tonic and flavored sparkling waters. Some have added sugar and even the ones with artificial sweeteners can lead to cavities and weight gain.

"While they still don't have calories or sugar they may be affecting our taste buds, our satiety, or hunger later in the day," explains Hyde.

Then there are drinks like seltzer and club soda, which are essentially bubbly water. Hyde says carbonated waters do pose a slight risk to people with irritable bowel syndrome because they can cause bloating, and club soda contains sodium. But overall Hyde says both are healthier choices than sugary sodas.

"We're drinking too many calories and so finding these alternatives is great," says Hyde.

For the healthiest alternative, Hyde suggests infusing regular water with your favorite fruit.
