What should you check?
Start with the drink’s intended use and its per-can sugar figure, then compare the flavour, ingredients and quantity you would actually choose.
| Priority | What to check | Your needs |
| Sugars per can |
Read the sugars figure for a 330ml can, not just the front-of-pack claim. Sainsbury’s lists less than 0.5g per can for its Diet Lemonade six-pack; ASDA lists 0g per 330ml can for 7UP Zero Sugar Lemon & Lime 24 x 330ml. |
I’m choosing a fizzy drink for an ordinary occasion and want to compare the sugar in the portion I’ll drink. |
| Intended use |
Keep routine drinks distinct from hypo treatment. Diabetes UK advises sugar-free alternatives to sugary fizzy drinks outside hypo treatment; follow your own care plan for a hypo. |
I don’t want to mistake a zero-sugar can for a drink intended to provide sugar during a hypo. |
| Label and flavour |
Check whether ‘no added sugar’ still comes with declared sugars. Sainsbury’s Diet Cloudy Lemonade contains fruit ingredients and lists 0.8g sugars per 330ml can; it is a different flavour style from plain diet lemonade. |
Cloudy lemonade appeals to me, but I still want to know what its nutrition panel says rather than assuming it contains zero sugar. |
| Sweeteners |
Read the current ingredients and any pack warning. Sainsbury’s lists aspartame and a source-of-phenylalanine warning for 7UP Zero Sugar Pink Lemonade 8 x 330ml; its Diet Lemonade lists sucralose and acesulfame K. |
If a particular ingredient or warning matters to me, I need to check the exact variant before choosing a pack. |
| Pack quantity |
Compare can size and count together. The cited retailer listings include six-, eight- and 24-can packs of 330ml cans. |
I’d rather choose the number of individual cans I can use and store than decide by the pack’s appearance alone. |

Questions about labels and use
How do zero-sugar cans fit into ordinary drink choices when managing diabetes?
Diabetes UK includes sugar-free soft drinks among drinks that count towards fluid intake and advises choosing them instead of sugary fizzy drinks outside hypo treatment. It describes water as its all-round choice; ask your diabetes team about questions specific to your care.
Can zero-sugar lemonade replace a drink used to treat a hypo?
No. Diabetes UK distinguishes sugary fizzy drinks used for a hypo from sugar-free alternatives chosen at other times. Follow your own hypo-treatment care plan.
Does ‘no added sugar’ mean there are no sugars in the can?
No. Sainsbury’s lists 0.8g sugars per 330ml can for its no-added-sugar Diet Cloudy Lemonade, which contains fruit ingredients. Check the per-can figure if you are comparing it with a zero-sugar drink.
Why does a zero-sugar can carry a phenylalanine warning?
Sainsbury’s lists aspartame and a source-of-phenylalanine warning for 7UP Zero Sugar Pink Lemonade 8 x 330ml. Check the ingredients and warning on the exact variant you choose, and seek individual clinical advice if that warning affects you.
Should I check the can after choosing a multipack online?
Yes. Use the label on the pack you receive for the current per-can nutrition, ingredients and warnings, especially when those details determine your choice.
