People packing one drink
Individual 330ml cans give you a defined serving without pouring from a larger bottle. Check the sugars and ingredients on the particular can: similar-looking citrus drinks can have different recipes.
Who is each format for?
People switching from a sugary fizzy drink
A no-added-sugar claim is a starting point, not the whole comparison. Read the sugars figure per 100ml and per serving, then check which sweeteners and fruit ingredients the drink contains.
Teams sharing an office fridge
A larger bottle provides several servings when people can keep it refrigerated after opening. Follow the period stated on its label rather than assuming it will last through an occasional series of lunches.
What should you check?
Start with the portion you will actually pack, then compare the label and the storage needed once the drink is opened.
| Priority | What to check | Your needs |
|---|---|---|
| Serving format | Check whether you are buying individual 330ml drinks or a 1L or 2L bottle. For a bottle, plan how you will pour and store the remaining servings. | For a single lunch, I want a portion I can pack without measuring. For shared lunches, a bottle could work if we have fridge space. |
| Listed sugars | Compare ‘of which sugars’ per 100ml and per serving on packs using the same basis. Sainsbury's lists 0.8g per can for its Diet Cloudy Lemonade 6x330ml, despite its no-added-sugar description. | I do not want to mistake ‘no added sugar’ for 0g sugars; the amount in the serving I drink matters. |
| Ingredients | Read the fruit ingredients and named sweeteners, not just the front-of-pack wording. If you have phenylketonuria (PKU), check for aspartame and the phenylalanine warning; the NHS says aspartame is unsuitable for people with PKU. | The sweetener or fruit ingredients may affect which drink I choose, even when two packs make similar sugar claims. |
| Flavour | Check whether the product is cloudy lemonade, standard diet lemonade or a lemon-lime soft drink. Sprite Zero Sugar, for example, is described as lemon-lime by Your Coca-Cola UK. | If I want lemonade specifically, a zero-sugar lemon-lime drink may not be the flavour I am looking for. |
| Opened-bottle storage | Read the exact bottle's instructions. Sainsbury's and M&S state that their cited cloudy lemonades should be refrigerated and used within three days of opening. | A larger bottle suits me only if it can be kept in the fridge and its remaining servings will be used in time. |
| Fizzy drinks at your desk | Do not use the sugar claim to judge acidity. The NHS notes that carbonated drinks are associated with dental erosion because of their acid content. | If I tend to sip a drink throughout the workday, I want to consider that separately from its sugars figure. |
Packed-lunch pitfalls
-
Reading ‘no added sugar’ as ‘0g sugars’
Fruit-containing recipes can still list sugars. Sainsbury's gives 0.8g per 330ml can for its Diet Cloudy Lemonade and 0.6g per 250ml glass for its bottled Cloudy Lemonade No Added Sugar.
Compare the sugars line per serving and per 100ml, then read the fruit and sweetener ingredients.
-
Opening a large bottle for one occasional lunch
The cited Sainsbury's, M&S and Asda bottles call for refrigeration after opening and use within three days.
Choose a bottle when you can store and use the remaining servings as directed; otherwise, consider an individual portion.
Any drink left beyond the bottle's stated use period may go to waste.
-
Overlooking the sweetener warning
The NHS says aspartame is unsuitable for people with PKU. The cited R. White's Diet Lemonade and Sprite Zero Sugar product information includes phenylalanine warnings.
Check the ingredients and warning on the exact pack if you need to avoid aspartame.
-
Assuming a lower-sugar fizzy drink has no dental consideration
The NHS associates carbonated drinks with dental erosion because of their acid content; the sugar figure does not answer that question.
Consider how often you drink fizzy lemonade, particularly if you would otherwise sip it throughout the day.
Brand and retailer examples
These particular drinks illustrate differences in portion size, recipe and storage instructions; a brand name alone does not settle the choice.

- Sainsbury's lists 13kcal and 0.8g sugars per can for the cloudy version; its standard diet lemonade lists 4kcal and less than 0.5g sugars per can.
- The 2L cloudy bottle needs refrigeration after opening and use within three days.

Frequently asked questions
Does ‘no added sugar’ mean lemonade contains no sugar?
No. A lemonade with no added sugar can still list sugars from its ingredients. For example, Sainsbury's lists 0.8g sugars per can for its Diet Cloudy Lemonade 6x330ml; check ‘of which sugars’ per 100ml and per serving on the drink you are buying.
Should I pack a can or buy a bottle for an office lunch?
An individual 330ml can gives you a ready-to-pack portion for one lunch. A larger bottle is worth considering for sharing or several servings if you can store it as directed; the cited Sainsbury's and M&S cloudy lemonade bottles say to refrigerate after opening and use within three days.
What should someone with PKU check on a lemonade label?
Check for aspartame and a phenylalanine warning on the exact pack. The NHS says aspartame is unsuitable for people with phenylketonuria (PKU); the cited R. White's Diet Lemonade and Sprite Zero Sugar product information carries relevant warnings.
Are sweeteners in no-added-sugar drinks considered safe?
The NHS says approved sweeteners are considered safe and acceptable alternatives to sugar. That does not tell you which sweetener a particular lemonade contains, so check its ingredients; aspartame remains unsuitable for people with PKU.
Does no added sugar remove the dental consideration of fizzy lemonade?
No. The NHS notes that carbonated drinks are associated with dental erosion because of their acid content. Consider that separately from the drink's sugar figure, particularly if you tend to sip it over a long period.
