If you want a drink with no sugars, check for 0 g sugars per 100 ml on the nutrition panel: ‘no added sugars’ does not necessarily mean the finished drink contains none. When you plan to sleep after a night shift, an explicitly caffeine-free option such as Pepsi Max Caffeine Free or Coca-Cola Zero Sugar Caffeine Free addresses both checks. For a fruit flavour, compare the figures carefully: Tesco lists 0.4 g sugars per 100 ml for Fanta Orange Zero.
If a fizzy drink is part of your shift snack and sleep is next, check caffeine as well as sugars. NHS night-shift guidance advises minimising caffeine in the evening; an explicitly caffeine-free label makes the drink easier to identify.
Pepsi UK lists 0 g sugars per 100 ml for both Pepsi Max and Pepsi Max Caffeine Free, but only the latter is the caffeine-free version. Coca-Cola Great Britain also lists 0 g sugars per 100 ml for Coca-Cola Zero Sugar Caffeine Free.
Flavour and sugar figure are separate decisions. Tesco lists 0 g sugars per 100 ml for Sprite Zero Sugar, while its Fanta Orange Zero listing gives 0.4 g per 100 ml and includes orange juice from concentrate.
Start with the sugar figure you actually want, then check caffeine against your planned sleep time and read the ingredients for anything you avoid.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read ‘of which sugars’ per 100 ml, not just the front label. The Advertising Standards Authority explained in 2025 that a ‘no added sugars’ claim concerns ingredients added for sweetening; it does not guarantee 0 g sugars in the finished drink. | If I want strictly 0 g sugars, I need that figure on the nutrition panel. Tesco lists 0.4 g per 100 ml for Fanta Orange Zero. |
| Caffeine | Look for an explicit caffeine-free designation and check the ingredients. Pepsi UK lists caffeine in standard Pepsi Max but describes Pepsi Max Caffeine Free as having none. | With sleep planned after my shift, I would choose a drink clearly labelled caffeine free rather than assume a zero-sugar claim covers caffeine too. |
| Sweeteners | Read the ingredient list for particular sweeteners. GOV.UK states that drinks naming aspartame in the ingredients must carry phenylalanine wording. | If I avoid a sweetener or need to account for phenylalanine, the full ingredients and warning matter more to me than the sugar claim alone. |
| Flavour | Compare the exact varieties, not just the flavour category: Tesco lists 0 g sugars per 100 ml for Sprite Zero Sugar and 0.4 g for Fanta Orange Zero, which contains 4% orange juice from concentrate. | I might prefer lemon-lime or orange to cola, but I still want the chosen drink’s own sugar figure before picking it. |
A no-added-sugars claim does not establish the amount of sugars in the finished drink. Tesco’s Fanta Orange Zero listing, for example, gives 0.4 g sugars per 100 ml.
Decide whether your requirement is no sugars added or a nutrition-panel figure of 0 g per 100 ml, then check the relevant wording.
