For an occasional half-term cola, choose a variety labelled zero sugar if avoiding sugar is the priority, and a variety explicitly labelled caffeine-free if caffeine also matters. For a child drinking regularly or between snacks, water or milk is a different choice: Medway Community Healthcare NHS Trust warns that fizzy drinks, including sugar-free ones, can wear away tooth surfaces.
A zero-sugar cola addresses the sugar content of the treat, but it does not make frequent sipping a tooth-friendly choice. Medway Community Healthcare NHS Trust warns that sugar-free fizzy drinks can wear away tooth surfaces.
Look for a named caffeine-free variety rather than assuming that every diet or zero-sugar cola is caffeine-free. The distinction matters even within a familiar product range.
Check the exact pack for sugar, caffeine, sweeteners and any relevant ingredient statement. A Diet or Zero Sugar name alone does not tell you whether a particular variety contains caffeine.
Start with the occasion: decide whether you want cola at all, then check the sugar and caffeine information on the exact variety you would buy.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Read sugars per 100ml on the nutrition panel. Check the exact variety rather than relying on Diet or Zero Sugar in the name. | I want an occasional cola without the sugar in a regular sugar-sweetened version. |
| Caffeine | Look for an explicit caffeine-free label and check the ingredients. Pepsi UK describes Pepsi Max Caffeine-Free as containing no caffeine, while its standard Pepsi Max ingredients list caffeine. | If avoiding caffeine matters in our household, I need the caffeine-free variety, not just a no-sugar cola. |
| When it is drunk | Consider whether this is an occasional drink or something a child will sip repeatedly. Medway Community Healthcare NHS Trust warns that fizzy drinks, including sugar-free ones, can wear away tooth surfaces. | For drinks between snacks or throughout the day, I would choose water or milk instead of treating zero-sugar cola as an everyday option. |
| Ingredients | Read the current ingredient list for sweeteners, acids and caffeine. Check for a phenylalanine statement if it is relevant to the shopper. | I need to check what is in this particular can or bottle, rather than assume two no-sugar recipes are interchangeable. |
Sugar-free cola is still a fizzy drink. Medway Community Healthcare NHS Trust warns that fizzy drinks, including sugar-free versions, can wear away tooth surfaces.
For children, keep cola an occasional choice rather than a drink to sip repeatedly between snacks; choose water or milk for regular drinking.

A no-sugar cola to consider when avoiding caffeine matters.

No-sugar does not mean tooth-friendly. Medway Community Healthcare NHS Trust warns that fizzy drinks, including sugar-free ones, can wear away tooth surfaces; water and milk are alternatives for regular drinking.
Choose a variety explicitly labelled caffeine-free when avoiding caffeine matters. Pepsi UK describes Pepsi Max Caffeine-Free as containing no caffeine, and Tesco says the same of Diet Coke No Caffeine; standard Pepsi Max and Diet Pepsi list caffeine among their flavourings. Check the exact pack rather than relying on its no-sugar name.
No. The Department for Education’s school food standards guidance for England lists permitted drinks but does not include cola. That school-food setting is distinct from a family’s private half-term snack at home; the England guidance does not establish rules for schools elsewhere in the UK.
The name does not settle caffeine or ingredient questions. Compare sugars per 100ml, the caffeine-free wording and ingredient list on the exact pack, and check any phenylalanine statement if it matters to the shopper.
