For an airport meal, check both the sugars value and ingredients: UK listings for Sprite Zero Sugar, 7UP Zero Sugar and R. White's Diet Lemonade state 0g sugars per 100ml, but zero sugar does not mean sweetener-free. A normal-sized drink is generally a purchase to make after security: GOV.UK says containers over 100ml cannot pass through security at most UK airports, so check the rules for your departure and any transfer airport.
If you want a lemon or lemon-and-lime fizzy drink with 0g sugars, where you buy it matters as well as what is on the label. GOV.UK says containers over 100ml cannot pass through security at most UK airports.
A zero-sugar label does not tell you which sweeteners a drink contains. Read the ingredients and any phenylalanine statement on the pack if either matters to your choice.
That preference is different from choosing no sugar. Marks & Spencer describes its Lemonade as having no artificial sweeteners, but lists sugar in its ingredients.
Check the drink itself first, then its pack size and the point in your journey when you plan to buy it.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars and ingredients | Read the sugars value and ingredient list on the exact pack. The Tesco Sprite Zero Sugar, Asda 7UP Zero Sugar and Ocado R. White's Diet Lemonade listings each state 0g sugars per 100ml. | I want a no-sugar drink with my meal, rather than assuming every product called lemonade meets that condition. |
| Sweeteners | Check which sweeteners are named and whether the pack carries a phenylalanine statement. If you prefer no artificial sweeteners, check the sugars value too: Marks & Spencer lists sugar in its Lemonade ingredients and 4.4g sugars per 100g. | A zero-sugar label is not enough for me if I also need to check a particular ingredient. |
| Airport security | Check the departure airport's current liquid-container rule and any transfer airport's rule. GOV.UK says containers over 100ml cannot pass through security at most UK airports, although rules have changed at some airports. | I do not want to buy a 330ml can or 500ml bottle before security if I cannot take it through. |
| Pack format | Distinguish a single drink from a multipack before ordering. A pack of eight or 24 cans provides individual 330ml portions but is not a single-can purchase. | For one airport meal, I only need one drink; a multipack makes more sense if I intend to use the remaining cans elsewhere. |
A 330ml can or 500ml bottle exceeds the 100ml container limit that GOV.UK says applies at most UK airports. Rules have changed at some airports, so the departure point matters.
Check your airport's current rule before buying a drink to carry through screening, or buy one after security if an outlet stocks it.
The checked Sprite Zero Sugar, 7UP Zero Sugar and R. White's Diet Lemonade formulations list sweeteners. A sugars value alone does not identify the ingredients you may wish to avoid.
Read the current pack's ingredients and any phenylalanine statement as well as its nutrition panel.
Marks & Spencer says its Lemonade has no artificial sweeteners, yet its ingredient list includes sugar and its nutrition panel lists 4.4g sugars per 100g.
Decide whether you are avoiding sugar, artificial sweeteners or both, then check those conditions on the exact drink.
Sprite Zero Sugar is a lemon-and-lime option. Tesco lists a 500ml format with 0g sugars per 100ml.
7UP Zero Sugar is another lemon-and-lime option. Asda lists a 500ml bottle with 0g sugars per 100ml.
R. White's Diet Lemonade is a lemonade-branded option. Ocado lists 0g sugars per 100ml for its 2L bottle.
These lemon and lemon-and-lime zero-sugar drink listings are multipacks with individual 330ml cans. Check the exact can label and plan around airport security; a multipack is not the same purchase as a single drink from an outlet after security.

This six-can lemon soda multipack offers a different format from a single airport purchase. Check its nutrition panel and ingredients on the exact pack; if comparing figures with drinks labelled per 100ml, keep the measurement basis in mind. GOV.UK says 330ml containers exceed the security limit at most UK airports.
Not at most UK airports. GOV.UK says liquids in containers over 100ml cannot pass through security at most airports, although rules have changed at some. Check the current rule at your departure airport and any airport where you will transfer.
Yes, if an airside outlet stocks the drink you want. If you will pass through security again during a transfer, check that airport's rules before travelling onward with it.
No. The checked ingredient information for Sprite Zero Sugar, 7UP Zero Sugar and R. White's Diet Lemonade lists sweeteners. Read the exact pack's ingredients and any phenylalanine statement if those details affect your choice.
Not necessarily. Marks & Spencer says its Lemonade has no artificial sweeteners, but lists sugar as an ingredient and 4.4g sugars per 100g. Check both the ingredient list and nutrition panel when choosing for a no-added-sugar preference.
