Families choosing a routine lunch drink
If your child takes a drink to school every day, water follows the advice from Cambridgeshire Community Services NHS Trust to replace fizzy drinks, including sugar-free ones.
Who is this decision for?
Families considering an occasional fizzy drink
If you are choosing a sparkling lemon drink occasionally, compare the precise variant rather than assuming every bottle under the same brand has the same sugar content.
Families checking school rules and ingredients
Check the school’s packed-lunch policy before sending a fizzy drink. For a sweetened or zero-sugar variant, read the current pack for sweeteners and any phenylalanine declaration relevant to your child.
What should you check before choosing?
Decide on the routine lunch drink first, then check school rules and the exact pack if you are considering an occasional alternative.
| Priority | What to check | Your needs |
|---|---|---|
| Routine drinking | Check whether the drink is fizzy and whether its ingredients list acids. Cambridgeshire Community Services NHS Trust advises replacing fizzy drinks, even sugar-free ones, with water. | For an everyday school lunch, I would pack water rather than treat zero-sugar lemonade as an equivalent choice. |
| School policy | Read the individual school’s packed-lunch or water-only policy. Southwark Council’s water-only policy, for example, addresses drinks brought with lunch. | Before packing a fizzy drink, I want to know whether my child’s school accepts it. |
| Exact variant | Read the sugar declaration for the precise bottle or can. Keep per 100ml and per 100g figures distinct, and check the ingredients rather than relying on a brand name. | If I buy an occasional fizzy drink, the label on that variant matters more to me than a familiar name or a zero-sugar claim on another product. |
| Sweeteners | Check the current pack for sweeteners and any statement that it contains a source of phenylalanine. Do not assume every formulation has the same ingredients. | Where an ingredient declaration is relevant to my child’s dietary requirements, I need to check the pack itself. |
Common packed-lunch mistakes
-
Assuming zero sugar means the same as water
A zero-sugar fizzy drink can still contain acids. Cambridgeshire Community Services NHS Trust advises avoiding fizzy drinks even when they are sugar-free.
Pack water for routine school lunches; consider a zero-sugar fizzy drink only as an occasional choice if the school permits it.
-
Comparing brand names instead of variants
Coca-Cola GB lists Sprite at 4.4g sugars per 100ml and Sprite Zero at 0g per 100ml. The variant changes what the sugar figure means.
Check the exact pack’s nutrition panel, including whether its values are stated per 100ml or per 100g.
-
Assuming the school accepts fizzy drinks
A school’s own policy can address drinks brought from home. Southwark Council’s water-only school policy specifically mentions drinks brought with lunch.
Read your child’s packed-lunch policy or ask the school before sending sparkling lemonade.
-
Relying on an older product listing
Marks & Spencer advises customers that product information can change, so an online ingredient or nutrition listing may not describe the pack in hand.
Use the current pack to check sugars, acids, sweeteners and any relevant ingredient declaration.
Lemonade brands and label differences
R. Whites
R. Whites lists several carbonated lemonade formulations on its official site.
- Its listings include a formulation with 3.9g sugars per 100ml and another described as containing negligible sugars.
- Formulations differ: check the exact pack for citric acid, sweeteners and any source-of-phenylalanine statement.
Sprite
Coca-Cola GB lists standard Sprite and Sprite Zero as separate lemon-and-lime fizzy drinks.
- Coca-Cola GB lists 4.4g sugars per 100ml for Sprite and 0g per 100ml for Sprite Zero, making the variant important when comparing sugar declarations.
- Both listings include acids. A zero-sugar declaration does not change NHS advice to avoid fizzy drinks as a routine choice.
M&S
Marks & Spencer lists sparkling cloudy lemonade and regular lemonade as distinct own-label products.
- Its product pages state 3.4g sugars per 100g for Sparkling Cloudy Lemonade and 4.4g per 100g for Lemonade.
- Both listed products contain citric acid. M&S advises checking the current pack because product information can change.

7 Up Lemonade Zero, 24 × 330ml
This larger pack is relevant only if you want an occasional fizzy-drink option, not a routine packed-lunch drink.

Questions about lemonade in packed lunches
Is sparkling lemonade an everyday school-lunch drink?
Choose water for a routine school packed lunch. Cambridgeshire Community Services NHS Trust advises replacing fizzy drinks, including sugar-free ones, with water; St George’s NHS guidance identifies fizzy and acidic drinks as a tooth-erosion concern.
Does zero sugar make fizzy lemonade equivalent to water?
No. Coca-Cola GB lists Sprite Zero at 0g sugars per 100ml, compared with 4.4g for Sprite, but its ingredient list still includes acids. NHS dental guidance advises avoiding fizzy drinks even when they are sugar-free.
Can my child take a fizzy drink to school?
Check your child’s packed-lunch policy before sending one. Southwark Council’s water-only school policy addresses drinks brought with lunch; Department for Education school-food guidance concerns food and drink provided by state-funded schools in England, rather than deciding what your individual school accepts from home.
What should I compare for an occasional fizzy drink?
Compare the exact variant’s sugar declaration, its per-100ml or per-100g basis, and its ingredients. Coca-Cola GB lists Sprite and Sprite Zero at 4.4g and 0g sugars per 100ml respectively; Marks & Spencer lists its Sparkling Cloudy Lemonade and Lemonade at 3.4g and 4.4g per 100g respectively. Check the current pack rather than treating those different measurement bases as interchangeable.
Why might a zero-sugar drink mention phenylalanine?
Some sweetened formulations carry a statement that they contain a source of phenylalanine; Coca-Cola GB lists one for Sprite Zero, and R. Whites lists one for some formulations. If that declaration matters to your child’s dietary requirements, check the exact current pack and follow the clinical advice applicable to them.
