Choose a smoothie if you want a smoothie-style drink rather than fizz; choose a sparkling fruit drink if carbonation matters more, and compare the exact ingredients and nutrition label before buying. If you are shopping before security, container size may settle the choice: GOV.UK says containers larger than 100ml cannot pass through security at most UK airports, even when partly full. For fruit juice and smoothies, NHS guidance also sets a combined daily limit of 150ml.
Check the bottle or can size before buying a drink to carry through the checkpoint. GOV.UK says containers larger than 100ml cannot pass through security at most UK airports, even if partly full; check the rules for your departure and transfer airports.
If you want a smoothie rather than a fizzy fruit drink, check the product description and ingredients. Innocent describes fruit and vegetables crushed into its smoothies, while retailers list smoothies separately from sparkling juice drinks.
Read the values on the exact pack rather than relying on “fruit” or “diet” in the name. Marks & Spencer lists 7.6g sugars per 100g for its sparkling apple drink; its diet pineapple-and-grapefruit drink lists 0.5g sugars per 100g and contains sucralose.
Choose it when: You want a drink sold as a smoothie, not carbonation.
Keep in mind: NHS guidance limits fruit juice and smoothies to a combined 150ml a day, so bottle size matters as well as airport rules.
Choose it when: Fizz and fruit flavour matter more to you than smoothie texture.
Keep in mind: Fruit wording does not tell you the sugar content; Marks & Spencer’s sparkling apple example lists added sugar.
Choose it when: You want fizz and are comparing the listed sugar values of specific drinks.
Keep in mind: Check sweeteners too: Marks & Spencer’s diet pineapple-and-grapefruit example contains sucralose.
Decide which drink format you want, then check the pack and where you plan to buy it.
| Priority | What to check | Your needs |
|---|---|---|
| Security | Check container capacity, not how much drink remains. GOV.UK says containers over 100ml cannot pass through security at most UK airports; check each airport on your journey. | I want to carry my drink through security, so I need a container the airport permits. Otherwise, I can buy it after the checkpoint or drink it beforehand. |
| Drink format | Read the description and ingredients for a smoothie-style drink or a carbonated fruit drink. Innocent describes fruit and vegetables crushed into its smoothies; Marks & Spencer’s sparkling apple drink starts with carbonated spring water. | If I want smoothie texture, a fizzy fruit flavour alone will not answer that need. If fizz is the point, I can compare sparkling drinks on their own terms. |
| Nutrition label | Compare sugars and energy using the same stated basis, and check the ingredients for sweeteners. Marks & Spencer lists 7.6g sugars per 100g for its sparkling apple drink and 0.5g per 100g for its diet pineapple-and-grapefruit drink, which contains sucralose. | I want to know what is in the particular drink I am buying, rather than assuming that “fruit”, “sparkling” or “diet” settles the comparison. |
| Portion size | Check the volume you intend to drink. The NHS advises limiting fruit juice and smoothies to a combined 150ml a day and having them at mealtimes. | A large smoothie bottle may contain more than I intend to drink with my airport food, even if I am buying it after security. |
GOV.UK says a container larger than 100ml cannot pass through security at most UK airports, even when partly full. The rule concerns the container, not just the drink left in it.
Check your departure and transfer airports’ rules before buying. If the container is too large, plan to finish the drink before the checkpoint or buy one after security.
Fizz and fruit flavour do not establish a smoothie-style ingredient base. Innocent describes fruit and vegetables crushed into its smoothies; Marks & Spencer’s sparkling apple drink contains carbonated spring water and apple juice from concentrate.
