If you want a fizzy drink for half-term snacks while reducing listed sugars, compare the exact diet or zero-sugar variant with its regular counterpart rather than relying on the brand name. If avoiding caffeine also matters, choose a variant explicitly labelled caffeine-free; check the ingredients and any phenylalanine statement when a prescribed diet makes them relevant.
When fizzy drinks are part of a half-term snack, the useful sugar comparison is between the regular drink and the exact diet or zero-sugar variant. The NHS names sugar-free and diet drinks among the alternatives to sugary fizzy drinks.
A zero-sugar label does not settle the caffeine question. Coca-Cola Great Britain lists caffeine flavouring for Coca-Cola Zero Sugar, while Pepsi UK lists caffeine in Pepsi Max and identifies Pepsi Max Caffeine Free as a separate option.
Some zero-sugar drinks list sweeteners and carry a source-of-phenylalanine statement. Where that statement matters to someone following a prescribed diet, check the exact pack against their dietary advice rather than choosing by the word “diet” alone.
Start with the exact variant and its nutrition panel, then check caffeine and ingredients separately. Flavour and pack size can help narrow the remaining options for the snack occasion.
| Priority | What to check | Your needs |
|---|---|---|
| Listed sugars | Compare sugars on the exact regular and diet or zero-sugar packs. Use the same basis, such as per 100 ml, when comparing different sizes. | I want a fizzy drink for a snack without assuming the regular and zero-sugar versions contain the same amount of sugar. |
| Caffeine | Look for an explicit caffeine-free variant and check its ingredients. Pepsi UK identifies Pepsi Max Caffeine Free as a zero-sugar, zero-caffeine option; its standard Pepsi Max product lists caffeine. | If caffeine avoidance matters in our household, a zero-sugar claim alone does not answer my question. |
| Sweeteners and phenylalanine | Read the ingredients and any source-of-phenylalanine statement on the chosen pack. Formulations can differ between variants. | Someone following a prescribed diet may need the exact ingredient and label information before I serve the drink. |
| Flavour and format | Check whether the variant is cola, citrus or fruit-flavoured, and confirm the can size and number in a multipack. | We might prefer a non-cola flavour or want individual cans for several snack occasions. |
| Where it is served | Distinguish a family snack at home from food supplied by a school. Department for Education school-food guidance concerns provision in state-funded schools in England. | I am buying for home during half term, rather than choosing drinks to be supplied through a school. |
A regular drink and its zero-sugar counterpart can have different listed sugar values. Coca-Cola Great Britain lists sugars for regular Fanta Orange, while its Sprite Zero information identifies a zero-sugar variant.
Check the full variant name and nutrition panel on the can or bottle, particularly when choosing a different flavour or multipack.
Coca-Cola Zero Sugar and Pepsi Max list caffeine or caffeine flavouring in their UK product information. Pepsi Max Caffeine Free is a distinct variant.
When caffeine avoidance matters, look for an explicit caffeine-free label and inspect the ingredients on the exact pack.
Department for Education guidance addresses food and drink provided in state-funded schools in England. That is a different setting from a family buying half-term snacks for home.
For school provision, check which nation, setting and current rules apply rather than treating a household purchase as the same decision.
Choosing a zero-sugar variant addresses its listed sugar content, but caffeine and other ingredients still need separate checks. The NHS also names water among alternatives to sugary fizzy drinks.
Choose the fizzy drink for the occasion and keep water available as another option.
These examples show why the full variant name matters; a brand name alone does not establish a drink’s sugar, caffeine or ingredient details.
Coca-Cola Zero Sugar is a cola option for shoppers comparing regular and zero-sugar variants.
Pepsi has distinct zero-sugar cola variants for different caffeine requirements.
Sprite Zero offers a lemon-and-lime route for shoppers who do not want cola.
Fanta gives fruit-flavour shoppers regular and zero-sugar variants to distinguish.
Dr Pepper is another flavour to consider when comparing regular and zero variants.
Tesco own-label drinks provide additional diet and zero-sugar variants to compare with branded options.

No. Coca-Cola Great Britain lists caffeine flavouring for Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in standard Pepsi Max. If caffeine avoidance matters, choose an explicitly caffeine-free variant and check its ingredients; Pepsi Max Caffeine Free is one zero-sugar example.
No. Regular and zero-sugar variants can list different amounts of sugar. Compare the full product name and the nutrition panel on the exact can or bottle, using the same quantity basis when comparing different serving sizes.
No. Department for Education guidance on school food concerns food and drink provided in state-funded schools in England, not a family’s snack purchase for home. If you are arranging school provision, check the rules applicable to that setting rather than applying a home-shopping choice.
It matters when someone’s prescribed diet requires that ingredient information. Several zero-sugar variants, including Coca-Cola Zero Sugar and Pepsi Max, carry a source-of-phenylalanine statement; check the exact pack and follow the person’s dietary advice rather than relying on a generic “diet” or “zero” label.
