Lunch-break shoppers comparing sugar
If you want fizz with lunch but are reducing sugar, compare the drink’s sugars per 100ml and the amount in the bottle or can. Water, zero-sugar drinks and standard fizzy drinks offer different choices.
Who is choosing?
Cola drinkers avoiding caffeine
If caffeine matters to you, look for an explicitly caffeine-free variant. Zero-sugar wording alone does not establish caffeine content: Coca-Cola GB and Pepsi UK list caffeine in standard zero-sugar cola variants.
Shoppers looking beyond cola
Lemon-lime, fruit-flavoured and flavoured-water options offer different tastes. Compare their sugar and ingredient labels separately rather than treating the flavour name as a guide to either.
What matters when choosing?
Start with whether you want water or a sweet soft drink, then check sugar and caffeine independently. The pack size matters when a bottle contains more than you plan to drink at lunch.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Compare sugars per 100ml on the current label. Check the bottle or can size as well as the amount you expect to drink. | I want fizz at lunch while cutting back on sugary drinks. The NHS suggests water or a diet, sugar-free or no-added-sugar swap. |
| Caffeine | Read the ingredients for caffeine or caffeine flavouring; look for an explicit caffeine-free designation when needed. | A zero-sugar cola appeals to me, but I also want to avoid caffeine. Coca-Cola GB and Pepsi UK distinguish their caffeine-free variants from standard zero-sugar colas. |
| Flavour and ingredients | Choose a flavour, then check sugars and sweeteners on that specific drink. For flavoured sparkling water, compare its ingredients with plain water. | I would rather have lemon-lime or fruit flavour than cola, but I do not want the flavour name to decide the sugar choice for me. |
| Serving format | Check the stated volume of each can or bottle and how many are in a multipack. Confirm the pack details on the product you buy. | A single can may suit my lunch break; if I choose a larger bottle or multipack, I want to know how much one drink contains. |
Common label mistakes
-
Assuming caffeine-free means sugar-free
Coca-Cola GB describes Fanta Orange as caffeine-free, but caffeine and sugar are separate label details.
Check sugars per 100ml as well as caffeine information if both affect your choice.
-
Reading “zero sugar” as “no caffeine”
Coca-Cola GB lists caffeine flavouring for Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in Pepsi Max.
Choose an explicitly caffeine-free variant when you want to avoid caffeine.
-
Treating flavoured water as plain water
Tesco lists 0g sugars per 100ml for its Orange & Mango Sparkling Water, while its ingredients include sucralose.
Choose plain sparkling water if that is the ingredient profile you want; otherwise, read the flavoured drink’s label.
-
Comparing only the per-100ml figure
A per-100ml sugar figure does not describe the total in a larger bottle.
Use it to compare drinks, then account for the amount you expect to drink and check the current pack label.
Relevant drink brands
Coca-Cola
Its UK cola range offers standard, zero-sugar and explicitly caffeine-free zero-sugar variants.
- Coca-Cola GB lists 0g sugars per 100ml for Coca-Cola Zero Sugar and describes Coca-Cola Zero Sugar Caffeine Free as free from both sugar and caffeine.
- Standard Coca-Cola Zero Sugar lists caffeine flavouring, so check which variant you have selected.
Pepsi
Pepsi Max and Pepsi Max Caffeine-Free serve different caffeine preferences within the zero-sugar cola range.
- Pepsi UK describes Pepsi Max Caffeine-Free as having zero sugar and zero caffeine.
- Pepsi UK lists caffeine among the flavourings in standard Pepsi Max.
Sprite
A lemon-lime alternative to cola, with a Zero Sugar variant for shoppers comparing sugar labels.
- Coca-Cola GB describes Sprite Zero Sugar as containing no sugar.
- Check the ingredients of the particular Sprite variant rather than assuming the standard and zero-sugar versions match.
Fanta
A fruit-flavoured route for shoppers who want to compare caffeine and sugar separately.
- Coca-Cola GB describes Fanta Orange as caffeine-free.
- Caffeine-free does not establish that a fruit-flavoured drink is sugar-free; compare the chosen variant’s nutrition label.
Dr Pepper
An alternative soft-drink flavour with a Zero variant for shoppers comparing sugar content.
- Coca-Cola GB describes Dr Pepper Zero as having zero sugar.
- Its listed flavourings include caffeine, so Dr Pepper Zero is not the caffeine-free route.
Tesco
Its sparkling-water range illustrates the distinction between plain and flavoured water.
- Tesco lists plain sparkling mineral water as well as flavoured sparkling-water products.
- Its Orange & Mango Sparkling Water lists sucralose despite reporting 0g sugars per 100ml; check the individual product label.

Questions about lunchtime fizzy drinks
Does zero sugar also mean caffeine-free?
No. Coca-Cola GB lists caffeine flavouring in Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in Pepsi Max. If you want to avoid caffeine, look for an explicitly caffeine-free variant, such as Coca-Cola Zero Sugar Caffeine Free or Pepsi Max Caffeine-Free.
What sparkling drink can I choose when reducing sugar at lunch?
Plain sparkling water is one option. If you want a sweet fizzy drink, the NHS suggests swapping sugary drinks for diet, sugar-free or no-added-sugar choices; check the specific drink’s label and the amount you plan to have.
Is a caffeine-free fruit drink necessarily sugar-free?
No. Coca-Cola GB describes Fanta Orange as caffeine-free, but caffeine status does not determine sugar content. Check both details on the variant you are buying.
Why check the can or bottle after comparing drinks online?
The current label lets you confirm the ingredients, nutrition information and serving size of the drink in your hand. Tesco advises shoppers to read product labels because its online food information can change.
