For lunch on the go, choose plain sparkling water if you want fizz without added flavouring; check the exact label if avoiding sugar or calories is essential. An unsweetened flavoured option may suit you if flavour matters, but compare its ingredients with those of a zero-sugar fizzy drink rather than treating the labels as interchangeable. Lancashire and South Cumbria NHS oral-health guidance notes that even sugar-free fizzy drinks are acidic and can wear away enamel, particularly relevant if you sip them repeatedly through the day.
If you take lunch to work or eat while travelling, a single-serving plain sparkling water is a straightforward option to check. For a flavoured drink, read the exact variant’s sugar and calorie information rather than relying on its category name.
Flavour may be important if plain water does not appeal. S.Pellegrino says its Essenza sparkling mineral water contains no sugars, sweeteners or calories; that claim applies to Essenza, not to every flavoured water.
A sugar-free label does not address acidity. Lancashire and South Cumbria NHS oral-health guidance says carbonated drinks are acidic and that even diet fizzy drinks can wear away enamel. How often you sip one matters when deciding what to drink throughout the working day.
Start with the exact drink and its label, then choose a serving you can carry and finish with lunch.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar and calories | Read the sugars and energy values for the exact variant, per 100ml and for the amount you plan to drink. Check a no-sweeteners claim separately from a zero-sugar claim. | I want fizz with lunch without choosing a drink that contains sugar; if calories matter too, I need to check both figures. |
| Serving format | Compare the individual container, not just the multipack: Highland Spring describes a 500ml bottle for use on the move, while S.Pellegrino describes its 330ml can as suitable for a quick meal on the go. | A smaller serving would fit alongside my packed lunch, rather than leaving me carrying an opened large bottle. |
| Frequency of fizz | Consider whether the drink is for one meal or for repeated sipping. Lancashire and South Cumbria NHS oral-health guidance says even diet fizzy drinks are acidic and can wear away enamel. | If I tend to sip fizzy drinks throughout the day, sugar-free wording alone does not settle my choice of everyday drink. |
| Flavoured ingredients | Check the exact flavour’s ingredient list and nutrition panel for sugar, sweeteners and other added ingredients. S.Pellegrino’s Essenza claims differ from the ingredients listed for Buxton Peak IMMUNO Grapefruit & Ginseng. | I would like flavour, but I want to know what is in this particular drink before choosing it over plain sparkling water. |
S.Pellegrino says Essenza contains no sugars or sweeteners, whereas the ingredient list for Buxton Peak IMMUNO Grapefruit & Ginseng includes sugar syrup, citric acid and sucralose. The word ‘flavoured’ does not distinguish those formulations.
Check the ingredients and nutrition panel for the exact flavour and pack. Treat sugar, sweeteners and calories as separate questions.
Lancashire and South Cumbria NHS oral-health guidance says carbonated drinks are acidic and that even diet fizzy drinks without sugar can wear away enamel.
If you frequently sip fizzy drinks, consider how often you choose a carbonated drink rather than using ‘zero sugar’ as your only check.
A large bottle may be awkward to carry or leave you with an opened drink after lunch. Highland Spring’s 500ml bottle and S.Pellegrino’s 330ml can are formats their manufacturers describe for drinking on the move.
Choose the individual serving around where and when you will drink it; a larger format may make more sense if you can leave it at your desk.

Eight 500ml bottles provide individual servings for taking with lunch. Highland Spring says its plain sparkling water has nothing added but bubbles; check the nutrition panel for this pack if a specific calorie value is important to your choice.
Yes, if the exact plain product’s label confirms no sugar. Highland Spring says its plain sparkling water has nothing added but bubbles, while Perrier states that its carbonated mineral water has no sugar and zero calories. Check flavoured and functional variants separately.
No. Lancashire and South Cumbria NHS oral-health guidance says carbonated drinks are acidic and that even diet fizzy drinks without sugar can wear away enamel. A zero-sugar claim tells you about sugar, not whether the drink is acidic.
A 330ml can or 500ml bottle is worth considering when you want one serving to carry with lunch. Highland Spring describes its 500ml bottle for use on the move, and S.Pellegrino describes its 330ml can for a quick meal on the go. Choose a larger bottle if you have somewhere to keep it and expect to use it beyond one lunch.
