For an office packed lunch, choose a zero-sugar cola if listed sugar is your main concern, or a version explicitly labelled caffeine-free if you also want to avoid caffeine. Regular cola suits someone who specifically wants the sugared recipe: Coca-Cola Great Britain lists 10.6g sugars per 100ml for Original Taste, while its Zero Sugar Caffeine Free variety lists 0g. Check the individual pack for sweeteners and any phenylalanine statement.
If you want cola with no listed sugar alongside lunch, compare the nutrition panels rather than can colours. Coca-Cola Great Britain lists 10.6g sugars per 100ml for Original Taste and 0g per 100ml for Zero Sugar Caffeine Free.
If you prefer not to have caffeine during the working day, look for a specifically caffeine-free variety. Coca-Cola Zero Sugar Caffeine Free and Pepsi Max No Caffeine are examples identified as both caffeine-free and zero-sugar by their brands.
A 330ml can gives you a defined drink to put beside a packed lunch. Check the can size as well as the number of cans in a multipack so the format fits how you plan to use it.
Decide whether sugar or caffeine changes your choice first, then check the ingredients and can format of the exact variety.
Choose when: You want neither listed sugar nor caffeine with lunch; Coca-Cola Zero Sugar Caffeine Free and Pepsi Max No Caffeine are labelled examples.
Trade-off: Check their sweeteners and phenylalanine statements if those ingredients matter to your choice.
Choose when: You want no listed sugar but do not need to avoid caffeine; Pepsi UK lists 0g sugars per 100ml for standard Pepsi Max.
Trade-off: Standard Pepsi Max lists flavourings including caffeine, so zero sugar does not make it a caffeine-free choice.
Choose when: You specifically prefer the standard sugared recipe rather than a zero-sugar variety.
Trade-off: Coca-Cola Great Britain lists 10.6g sugars per 100ml and caffeine flavouring for Original Taste.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Compare sugars per 100ml on the same basis. Check whether the label describes the regular or zero-sugar recipe. | I want to know whether the can contains the regular sugared recipe or a zero-sugar variety, rather than judging by its colour or brand. |
| Caffeine | Look for an explicit caffeine-free variety and check the ingredients. Standard zero-sugar colas can list caffeine flavouring. | If I would rather avoid caffeine at lunch, a zero-sugar label alone does not settle my choice. |
| Ingredients | Read the sweetener list and any phenylalanine statement on the current pack. Formulations differ between varieties. | I need to check the ingredients against any dietary instructions that apply to me, not assume that all zero-sugar colas use the same sweeteners. |
| Can format | Check the volume of each can and the number of cans in the pack. A multipack count is not a serving size. | One can needs to fit conveniently beside my packed lunch; the rest of the multipack can stay at home. |
