People replacing sugary fizzy drinks
If you want to keep the fizz without choosing a sugary soft drink, start with plain sparkling water. Diabetes UK describes water as an all-round drink; check the ingredients on the bottle you buy.
Who is choosing sparkling water?
The useful distinction is between plain water with bubbles and flavoured drinks whose sugars and other ingredients vary by product.
People who prefer a flavoured drink
A sugar-free flavoured option may suit your taste, but it is not the same formulation as plain water. Compare the sugars row and ingredients for the exact flavour rather than relying on the words “sparkling water”.
People concerned about dental erosion
Oxford Health NHS Foundation Trust identifies fizzy and fruit-flavoured drinks as acidic-drink categories. If erosion is already a concern, discuss drinking frequency with your dental professional rather than judging a drink by its sugar label alone.
What should you check?
Choose the type of drink first, then check the exact bottle or can: a plain sparkling water and a sugar-free flavoured drink answer different preferences.
| Priority | What to check | Your needs |
|---|---|---|
| Plain ingredients | Read the ingredients for the exact product. If you want plain water, look for water or mineral water and carbonation, without flavourings or sweeteners. | I want fizz without choosing a flavoured or sweetened drink. Diabetes UK describes water as an all-round drink. |
| Flavoured drinks | Check the sugars row and the full ingredients list. Volvic UK labels Touch of Strawberry Sparkling sugar-free with 0g sugars; it also lists citric acid, acesulfame K and sucralose. | Flavour matters to me, but I want to know whether the particular drink contains sugar, sweeteners or added acids. |
| Dental considerations | Consider whether the drink is fizzy or fruit-flavoured and how often you drink it. Oxford Health NHS Foundation Trust identifies both as acidic-drink categories. | If dental erosion concerns me, a sugar-free label alone does not settle my choice. |
| Purpose of the drink | Keep everyday drinks separate from your agreed hypo-treatment supplies. Plain water and drinks labelled 0g sugars do not provide sugar for treating a hypo. | I need an everyday drink, not a substitute for the hypo treatment agreed with my diabetes team. Diabetes UK discusses sugary fizzy drinks specifically in the context of treating hypos. |
Common buying mistakes
-
Assuming every “sparkling water” is plain water
Flavoured products can have quite different ingredients. Volvic UK lists citric acid and two sweeteners in its sugar-free Touch of Strawberry Sparkling, while Buxton Water lists sugar syrup and 8g sugars per bottle in its separate Peak IMMUNO Grapefruit & Ginseng drink.
Read the ingredients and sugars row for the exact range, flavour and pack size. If you want neither sugar nor sweeteners, check a plain sparkling-water label instead.
-
Keeping only sugar-free drinks for a hypo
Plain sparkling water and a drink labelled 0g sugars do not supply sugar for treating a hypo. Diabetes UK distinguishes everyday drinks from sugary fizzy drinks used for that purpose.
Keep the hypo treatment agreed with your diabetes team separate from the sparkling water you buy for everyday drinking.
-
Using the sugar label as the only dental check
A drink can be sugar-free and still be fizzy or fruit-flavoured. Oxford Health NHS Foundation Trust identifies these as acidic-drink categories relevant to dental erosion.
If you have erosion concerns, ask your dental professional about drinking frequency rather than relying on “sugar-free” alone.
Brand and retailer references
These examples illustrate different formulations and pack formats; a brand name alone does not identify the ingredients of every drink in its range.

evian describes its sparkling product as natural mineral water with added bubbles, in formats including 1L bottles and 33cl cans.
- An option to consider if you want sparkling mineral water rather than a named fruit flavour.

Questions about sparkling water
Is plain sparkling water an everyday option if I have diabetes?
Plain sparkling water is an option when you want fizz without sugars or sweeteners: check that the current ingredients list contains only water or mineral water and carbonation. Diabetes UK describes water as an all-round drink; follow any individual advice you have been given about your drinks.
Can I choose a sugar-free flavoured sparkling drink instead?
Yes, if you want flavour, but check both the sugars row and ingredients for the exact product. Volvic UK labels Touch of Strawberry Sparkling with 0g sugars and lists citric acid, acesulfame K and sucralose, making it a different choice from plain water.
Can plain or sugar-free sparkling water treat a hypo?
No: a drink without sugar does not provide the sugar used to treat a hypo. Diabetes UK discusses sugary fizzy drinks specifically as a hypo-treatment option; follow the treatment plan agreed with your diabetes team.
Does sparkling water matter if I am concerned about dental erosion?
It can be relevant even when the drink is sugar-free. Oxford Health NHS Foundation Trust identifies fizzy and fruit-flavoured drinks as acidic-drink categories; if you have erosion concerns, ask your dental professional about drinking frequency.
