Choose plain sparkling water if you want fizz without added flavourings or sweeteners. If you prefer flavour, distinguish a product labelled as having no sweeteners from a no-added-sugar drink that may contain them; check the ingredients as well as the nutrition panel. For a quick desk lunch, the bottle or can size and any storage instructions also matter.
The useful distinction is not simply fizzy versus still: it is whether you want plain water, flavour without sweeteners, or a flavoured drink whose label permits sweeteners.
If you want a fizzy lunch drink, compare sugars on the nutrition panel rather than relying on words on the front of the bottle. The NHS includes sparkling water among options for people who dislike the taste of still water and advises swapping sugary drinks for diet, sugar-free or no-added-sugar alternatives.
Flavoured sparkling drinks need a closer look at the ingredient list. Sanpellegrino says its S.Pellegrino Essenza range contains no sweeteners, whereas Sainsbury’s lists sucralose in its no-added-sugar Lemon & Lime sparkling drink.
If you sip a drink through the afternoon and are concerned about tooth wear, distinguish unflavoured carbonated mineral water from flavoured drinks. UK government oral-health guidance says unflavoured carbonated mineral water is fine for teeth, while noting that tooth wear has multiple causes.
Start with the drink type and its label, then choose a format that works for one lunch or for repeated use at your desk.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Compare sugars per 100ml and per serving on the nutrition panel. Check the exact drink rather than assuming that every flavoured sparkling water has the same formulation. | I want fizz with lunch while keeping track of the sugars in the drink I actually buy. |
| Flavour and sweeteners | Read the ingredient list for flavourings, sweeteners and acids. A no-added-sugar label does not, by itself, mean no sweeteners: Sainsbury’s Lemon & Lime sparkling drink lists sucralose and citric acid. | Flavour appeals to me, but I may want to avoid sweeteners. Sanpellegrino describes its S.Pellegrino Essenza range as containing no sweeteners; I would still check the flavour and pack I choose. |
| Regular sipping | Distinguish plain, unflavoured carbonated mineral water from flavoured fizzy drinks. UK government oral-health guidance says the unflavoured water is fine for teeth and describes tooth wear as multifactorial. | My lunch drink may stay on the desk for the afternoon, so I do not want to assume that all fizzy waters have identical ingredients or the same dental considerations. |
| Pack and storage | Check the size of each bottle or can, not just the multipack total. Read the exact product’s instructions for storage after opening; Ocado’s M&S 4 x 2L sparkling-water listing says to refrigerate and consume within three days. | A smaller portion fits a single lunch, while a larger bottle makes more sense if I can store it and use it again within its labelled period. |
Sainsbury’s no-added-sugar Lemon & Lime sparkling drink lists sucralose and citric acid, and its nutrition panel reports less than 0.5g sugars per 100ml. Those details describe different aspects of the drink.
Check both the nutrition panel and ingredients. If avoiding sweeteners is important, look for an explicit no-sweetener statement on the exact product or choose plain sparkling water.
UK government oral-health guidance specifically says unflavoured carbonated mineral water is fine for teeth; that statement should not be applied automatically to flavoured drinks with different ingredients.
For frequent desk drinking, check whether the product is unflavoured and read flavoured products’ ingredient lists. If you have tooth sensitivity or known tooth wear, ask a dental professional about your circumstances.
A large bottle may remain open well beyond the meal. Ocado’s listing for M&S Sparkling Scottish Mountain Water 4 x 2L instructs shoppers to refrigerate it and consume it within three days of opening.
Choose a smaller individual portion for a single lunch, or check that you have storage and a plan to use a larger bottle within its own labelled period.
These examples help distinguish drink types and pack formats; a brand name alone does not settle the ingredients of a particular product.

Choose plain sparkling water if you want fizz without choosing a flavoured or sweetened drink; choose another option by its actual ingredients and nutrition panel. The NHS suggests sparkling water for people who dislike still water and includes diet, sugar-free and no-added-sugar drinks among alternatives to sugary drinks, but those labels do not make the products interchangeable.
No. Sainsbury’s no-added-sugar Lemon & Lime sparkling drink lists the sweetener sucralose and reports less than 0.5g sugars per 100ml. Read the ingredients if avoiding sweeteners matters to you, and use the nutrition panel to check sugars in the exact drink.
Do not assume they are alike. UK government oral-health guidance says unflavoured carbonated mineral water is fine for teeth and notes that tooth wear is multifactorial; a flavoured drink may have other ingredients. Check its label, and seek individual dental advice if you have sensitivity or known tooth wear.
Follow the storage instructions on that bottle. Ocado’s M&S 4 x 2L sparkling-water listing says to refrigerate after opening and consume within three days, so check whether you can store and use a large bottle within its labelled period before choosing it for lunches.
