For an office packed lunch, a 330ml can makes the serving size clear; choose the recipe by deciding whether sugar, caffeine or particular ingredients matter to you. A caffeine-free, zero-sugar cola suits someone avoiding both sugar and caffeine, while a standard zero-sugar cola suits someone comfortable with caffeine. Sugar-free fizzy drinks can still be acidic: Wirral Community Health and Care NHS Foundation Trust warns that they can contribute to tooth wear.
If you want a cola with less sugar than a regular recipe and are comfortable checking sweeteners, compare the exact variants. Pepsi UK lists 0g sugars per 330ml for Pepsi Max and Pepsi Max Caffeine Free; Joybuy lists 0g per 330ml for Coca-Cola Zero Sugar.
A zero-sugar label alone does not settle the caffeine question. Pepsi UK distinguishes Pepsi Max, which contains caffeine, from Pepsi Max Caffeine Free.
Orange and lemon-lime drinks offer different flavours in lunch-sized cans. Tesco Groceries lists Fanta Zero Orange and Sprite Zero Sugar in 8 × 330ml packs; check the exact pack for any ingredient requirement.
Start with the recipe, then check the individual can and the number of cans you will use. A flavour name or front-of-pack zero-sugar claim cannot answer every ingredient question.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar per can | Compare sugars per 100ml and per can, keeping the recipe and serving size together. Pepsi UK lists 15g sugars in a 330ml regular Pepsi and 0g in a 330ml Pepsi Max. | If a fizzy drink is part of my regular lunch, I want to know the sugar total for the can I will actually drink. |
| Caffeine | Read the exact variant and ingredient list. Pepsi UK identifies Pepsi Max Caffeine Free separately from Pepsi Max, which contains caffeine. | For a caffeine-free lunch, I would choose a drink explicitly labelled caffeine-free rather than assume zero sugar means no caffeine. |
| Sweeteners | Check the ingredients and any phenylalanine statement on the exact pack. GOV.UK food-labelling guidance specifies that statement for products containing aspartame. | Some sweeteners may not suit my requirements, so the ingredient list matters more to me than the flavour name. |
| Flavour | Choose between cola, orange and lemon-lime, then check the chosen variant’s label. Tesco Groceries lists Fanta Zero Orange and Sprite Zero Sugar in 8 × 330ml packs. | I would rather pack an orange or lemon-lime drink than a cola, without assuming that different flavours have identical recipes. |
| Pack format | Check can volume, pack count and the best-before date. A multipack supplies individual cans but also needs storage space. | A sealed can is convenient for my lunch; I also want a pack count I am likely to use. |
| Acidity | Do not treat zero sugar as a statement about acidity. Wirral Community Health and Care NHS Foundation Trust notes that sugar-free and diet fizzy drinks can still be acidic and contribute to tooth wear. | If I drink something fizzy at lunch, I do not want to mistake a sugar-free label for a reason to sip it throughout the day. |
Pepsi UK lists caffeine in Pepsi Max but offers Pepsi Max Caffeine Free as a separate variant. The front-of-pack sugar claim does not distinguish the two.
If caffeine matters to you, read the exact variant name and ingredient list before choosing a can.
Wirral Community Health and Care NHS Foundation Trust notes that sugar-free and diet fizzy drinks can still be acidic and contribute to tooth wear.
Keep water in mind as a non-fizzy everyday drink rather than using a zero-sugar label as a measure of acidity.
Pepsi UK lists 15g sugars in a 330ml can of regular Pepsi. The amount in a full can is the more useful figure when that is the serving you plan to pack.
Compare the can totals for the particular regular and zero-sugar recipes you are considering.
An appealing flavour does not tell you whether the cans are the size you want or how much space the pack will take up.
Check the can size, pack count and best-before date against how often you expect to pack one.
These are examples of recipes and formats to compare, not a list of brands available in the product selection below.
Pepsi UK provides regular, zero-sugar and caffeine-free zero-sugar cola variants relevant to the lunch decision.
Coca-Cola Zero Sugar is a cola option for shoppers comparing individual cans in a larger multipack.
Fanta offers orange-flavoured alternatives for lunch packers who do not want cola.
Sprite Zero Sugar is a lemon-lime alternative to the cola and orange options.
Dr Pepper provides another flavour to consider if you want a change from standard cola.
Tesco own-label fizzy drinks add orange and lemonade recipes to the flavour comparison.
These individual-can multipacks cover cola and non-cola flavours for office lunches. Compare each named variant for sugar, caffeine and ingredients rather than treating the packs as interchangeable.

No image available
A no-caffeine cola variant in a 24-pack of 330ml cans. Check the can’s sugar figure and ingredient list alongside its caffeine-free wording, particularly if sweeteners matter to you.

A cola option when both sugar and caffeine are deciding factors. Pepsi UK describes Pepsi Max Caffeine Free as having no sugar or caffeine; this pack contains 24 individual 330ml cans. Check the sweeteners on the exact pack if relevant.

An apple-flavoured alternative to cola in a 24-pack of 330ml cans. If you need to avoid caffeine, check the can label before choosing it; check the sweeteners there too if they affect your choice.
It removes the sugar difference shown between some regular and zero-sugar recipes, but zero sugar does not mean the drink is non-acidic. Wirral Community Health and Care NHS Foundation Trust notes that diet and sugar-free fizzy drinks can contribute to tooth wear; water remains a non-fizzy option for everyday drinking.
Look for an explicitly caffeine-free variant and check its ingredient list. Pepsi UK lists caffeine in Pepsi Max but describes Pepsi Max Caffeine Free as containing no caffeine, despite both being zero-sugar variants.
GOV.UK food-labelling guidance specifies the wording “Contains a source of phenylalanine” for products containing aspartame. If you need to avoid that ingredient, check the exact can’s ingredient list rather than relying on a zero-sugar claim.
Use both figures, but the per-can total shows what is in the serving you plan to pack. Pepsi UK lists 15g sugars in a 330ml can of regular Pepsi and 0g in a 330ml serving of Pepsi Max; compare the labels of the particular drinks and can sizes you are considering.
Follow the storage directions and best-before date on the pack. The Joybuy Pepsi Max listing specifies a cool, dry place for storage; you can chill a can before drinking if you prefer it cold.
