What are the differences between sparkling mineral water and soda?

Quick answer

Sparkling water, as Healthline describes it, gets its bubbles naturally from a spring or well and contains natural minerals; plain versions have no sugar or calories. Regular soda is a sweetened drink, so it contains sugar or sweeteners and calories. The word soda can also mean club soda, which is plain carbonated water with added minerals and also has zero calories.

What is the difference between sparkling mineral water and soda?

The main difference is what is in the glass besides bubbles. Sparkling mineral water carries naturally occurring minerals and has no sugar or calories. A sweetened soda carries sugar or sweeteners. The confusion comes from the word soda, which people use for both sugary soft drinks and club soda or soda water.

Comparison of common fizzy waters

Drink Bubbles Minerals or additives Calories and sugar (12 oz)
Sparkling mineral water Natural bubbles from a spring or well (per Healthline) Calcium, sodium, magnesium from the source 0
Club soda Carbon dioxide injected Added salts such as sodium bicarbonate 0
Seltzer Carbon dioxide injected Generally none added 0
Tonic water Carbonated Added minerals and quinine About 124 calories and 32 g sugar in one reported example

Healthline notes that the minerals in club soda and sparkling water mostly affect taste and are unlikely to give health benefits at those amounts.

Is sparkling mineral water healthier than soda?

Plain, unsweetened sparkling water has no calories or sugar, so it is an easy swap for sweet soda. Sweetened soda adds sugar and calories. Do not assume health benefits beyond that; claims about digestion, weight or disease are not established by the sources checked here.

How to choose

  • Read the ingredients: plain mineral water lists only water, carbon dioxide and sometimes minerals.
  • Check flavored waters for sugar or sweeteners.
  • Choose club soda or seltzer as a cocktail mixer; tonic water is sweet and bitter, so it changes a drink more.

Common mistakes

  • Treating tonic water as a zero calorie mixer.
  • Assuming every drink labeled sparkling is unsweetened.
