For a weekly shop, choose the exact variant by flavour, its sugar declaration and whether caffeine matters: Coca-Cola Zero Sugar and Pepsi MAX are cola options, Sprite Zero offers lemon and lime, and Pepsi MAX Caffeine Free is explicitly caffeine free. Check each pack’s nutrition and ingredients rather than assuming every drink in a brand family is the same; the NHS also associates carbonated drinks with dental erosion because of their acidity.
If you want a choice of cola and other flavours at home, compare the exact Zero, No Sugar or No Added Sugar variants before deciding on pack sizes. A standard drink and its Zero variant can have different nutrition information.
Pepsi UK describes Pepsi MAX Caffeine Free as both no sugar and caffeine free. Standard Pepsi MAX and Coca-Cola Zero Sugar list caffeine, so a no-sugar label alone does not answer the caffeine question.
If phenylalanine warnings matter to your household, check the ingredients of each variant, particularly for aspartame. The NHS also notes that the acidity of carbonated drinks is associated with dental erosion, whether or not the drink contains sugar.
Choose the flavour and exact variant first, then check caffeine, ingredients and a pack size that fits how your household will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar declaration | Read the full variant name and sugars per 100ml on its nutrition panel. Do not treat Zero and No Added Sugar wording as interchangeable. | I want the particular drink I put in the basket to meet my sugar requirement, not just another product from the same brand. |
| Flavour | Compare cola with lemon-and-lime or fruit-flavour variants. Coca-Cola Great Britain describes Sprite Zero as a no-sugar lemon-and-lime option; check the individual Fanta Zero flavour’s panel. | Some people at home prefer cola, while others would choose a different flavour. |
| Caffeine | Look for an explicit caffeine-free declaration. Pepsi UK identifies Pepsi MAX Caffeine Free as no sugar and zero caffeine; its standard Pepsi MAX product is a different variant. | If caffeine avoidance matters in my household, I need the specific caffeine-free drink. |
| Ingredients and acidity | Check sweeteners and any phenylalanine warning on the pack. The NHS associates carbonated drinks with dental erosion because of their acidity. | I need to account for an ingredient restriction and not assume that removing sugar removes every consideration. |
| Pack format | Confirm the variant before comparing can multipacks and larger bottles. Tesco’s listings include 24 × 330ml zero-sugar cola packs and a 2L no-sugar, caffeine-free cola bottle. | For a weekly shop, I want a format the household can use and store conveniently. |
