For a fizzy drink with weekday breakfast, compare sugars per 100ml on the exact pack and choose a variant explicitly marked caffeine free if you want to avoid caffeine. Coca-Cola Zero Sugar Caffeine Free and Pepsi Max Caffeine Free list 0g sugars and no caffeine; Tesco describes Fanta Orange Zero as caffeine free but lists 0.4g sugars per 100ml. Medway Community Healthcare cautions that acidic fizzy drinks, including sugar-free ones, can wear away tooth surfaces.
The useful distinction is not just cola versus fruit flavour: the exact variant also determines what its label says about sugars and caffeine.
If you want cola with breakfast but not caffeine, compare variants explicitly named caffeine free. Coca-Cola Zero Sugar Caffeine Free and Pepsi Max Caffeine Free both list 0g sugars per 100ml in their GB product information; standard Pepsi Max lists caffeine among its ingredients.
Orange, lemon-lime and other flavours offer alternatives to cola, but their labels differ. Tesco describes Fanta Orange Zero as caffeine free while listing 0.4g sugars per 100ml; its Dr Pepper Zero listing shows 0g sugars per 100ml but includes caffeine.
Tesco No Added Sugar Cream Soda is a 2L vanilla-flavoured example. Tesco lists 0g sugars per 100ml and says to consume the bottle within three days of opening, making the intended use of a larger bottle worth considering.
Start with the sugar panel, then check caffeine on the exact variant. Flavour, ingredients and pack size can narrow the choice once those requirements are clear.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read total sugars per 100ml and per can or serving on the exact variant. Do not treat a front-of-pack no-sugar description as a substitute for the nutrition panel: Tesco lists Fanta Orange Zero at 0.4g per 100ml and 1.3g per 330ml. | If I would otherwise have a sugary fizzy drink at breakfast, I want to compare its sugar content with a sugar-free or no-added-sugar option. The NHS suggests these alternatives when reducing free sugars from sugary drinks. |
| Caffeine | Look for an explicit caffeine-free statement and check the ingredient list. Pepsi UK lists caffeine in standard Pepsi Max, whereas its Pepsi Max Caffeine Free variant is described as having no caffeine. | I want a cola or fruit flavour in the morning without assuming that a zero-sugar label also means caffeine free. |
| Flavour | Compare the exact cola, orange or lemon-lime variant rather than relying on the brand name. Coca-Cola Great Britain lists 0g sugars per 100ml for Sprite Zero, but its cited product information does not explicitly describe that variant as caffeine free. | Perhaps I would rather have lemon-lime or orange than cola. If avoiding caffeine matters too, I will check that requirement separately on the pack. |
| Ingredients | Read the sweetener list and any source-of-phenylalanine statement on the current pack. Check the particular variant, as ingredient information need not be identical across a range. | If certain sweeteners or phenylalanine information matter to me, the exact ingredient label matters more than the drink's zero-sugar name. |
| Use and pack size | Choose a can multipack or bottle size you can use as intended, and read its storage instructions. Tesco says its 2L No Added Sugar Cream Soda should be consumed within three days of opening. | A single can may suit my weekday routine; for a larger household bottle, I want to know its instructions after opening. |
| Acidity | Do not use sugar content alone to judge the effect of frequent sipping. Medway Community Healthcare warns that acidic fizzy drinks, including sugar-free versions, can wear away tooth surfaces. | I may choose a fizzy drink for flavour without making it the drink I sip throughout every breakfast. |
Pepsi UK lists 0g sugars per 100ml for both standard Pepsi Max and Pepsi Max Caffeine Free, but the standard variant includes caffeine in its ingredients. Tesco's Dr Pepper Zero listing also includes caffeine.
If you want to avoid caffeine, check the full variant name and ingredient list rather than the sugar claim alone.
Tesco describes Fanta Orange Zero as a no-sugar drink, while its nutrition panel lists 0.4g sugars per 100ml. Other cited variants, including Tesco No Added Sugar Cream Soda, list 0g per 100ml.
Compare the nutrition panels for the can or serving size you intend to drink.
Medway Community Healthcare cautions that acidic fizzy drinks can wear away tooth surfaces even when they are sugar free.
Consider how often you sip a fizzy drink, not just whether its label says zero sugar.

No. Read the nutrition panel for the exact drink and serving size. Tesco lists 0g sugars per 100ml for its No Added Sugar Cream Soda, while its Fanta Orange Zero listing shows 0.4g per 100ml and 1.3g per 330ml despite describing it as a no-sugar drink.
Coca-Cola Great Britain describes Coca-Cola Zero Sugar Caffeine Free as having no caffeine, Pepsi UK says the same of Pepsi Max Caffeine Free, and Tesco describes Fanta Orange Zero as caffeine free. Standard Pepsi Max and the cited Dr Pepper Zero variant list caffeine in their ingredients, so check the exact name rather than the brand alone.
No. Medway Community Healthcare warns that acidic fizzy drinks, including sugar-free ones, can wear away tooth surfaces. A zero-sugar label answers a question about sugars, not acidity or frequent sipping.
