For a first food shop, start with diet, no-added-sugar or zero-sugar lemonade if you want a sweet fizzy drink while reducing sugar; confirm the sugars figure per 100ml rather than relying on the name alone. Choose a bottle or cans according to how much your household will drink, and check the sweeteners if a particular ingredient matters to you.
Who is this choice for?
Shoppers cutting back on sugar
If you want a fizzy drink in the fridge without routinely choosing a sugary one, compare the sugars figures per 100ml. The NHS suggests sugar-free, diet or no-added-sugar drinks as alternatives to sugary fizzy drinks when cutting down on sugar.
Households sharing a bottle
A large bottle may fit a shared shop if it will be finished within the period stated on its label after opening. Check the storage instructions and whether the household is comfortable with its sweeteners before choosing a size.
Shoppers checking sweeteners
Diet and zero-sugar drinks can use different sweeteners. If aspartame is relevant to your household, particularly where phenylketonuria (PKU) applies, read the ingredients and any phenylalanine warning on the exact product.
What should you check?
For a first shop, compare the drink itself before deciding which pack format will work at home.
| Priority | What to check | Your needs |
| Sugars |
Compare sugars per 100ml on the nutrition panels. Read the full product description: sweeteners in the ingredients do not mean the drink contains no sugar. |
I want to reduce sugar from fizzy drinks without assuming every lemonade, or every drink containing sweeteners, has the same sugar content. |
| Sweeteners |
Look for named sweeteners in the ingredients. Check for aspartame or E951 and a phenylalanine statement where PKU is relevant. |
Everyone sharing the drink needs to be comfortable with its ingredients; a zero-sugar name alone does not tell me which sweeteners it uses. |
| Pack format |
Check bottle volume or can size, then read the instructions for storing an opened bottle. ASDA Diet Lemonade 2 Litres and M&S Diet Lemonade both instruct shoppers to refrigerate after opening and consume within three days. |
If several people will drink it soon, a larger bottle could work. For less frequent servings, I would compare smaller bottles or cans. |
| Drink style |
Check whether the product is lemonade or a lemon-and-lime drink. Compare regular and diet variants separately: ASDA Groceries lists 2.4g sugars per 100ml for its R. White's regular lemonade cans. |
I may prefer traditional-style lemonade or a lemon-and-lime flavour, but I do not want a regular variant mistaken for a zero-sugar one. |
Common buying mistakes
-
Assuming sweeteners mean zero sugar
A drink can contain both. ASDA Groceries lists sugar and sweeteners in its R. White's regular lemonade cans, with 2.4g sugars per 100ml.
Compare the sugars figure per 100ml and confirm which regular, diet or zero-sugar variant you are holding.
-
Skipping the ingredient list
Zero-sugar drinks do not all use the same sweeteners. The Sainsbury's listing for Sprite Zero Sugar 2L, for example, names aspartame alongside acesulfame K and sucralose.
If PKU applies, check the exact drink for aspartame or E951 and a phenylalanine warning before choosing it.
-
Buying a large bottle without checking its opened life
A bottle that suits a shared shop may be less practical if it will not be finished within its stated period after opening. The ASDA and M&S diet lemonade instructions cited above say to refrigerate and consume within three days.
Compare that instruction with how much your household is likely to drink; consider cans or a smaller bottle for less frequent servings.

Frequently asked questions
Does zero-sugar lemonade tell me everything about the drink?
No. It does not identify the sweeteners, pack size or storage instructions. The NHS notes that lower- and no-calorie sweeteners can help reduce sugar intake, but do not by themselves establish the overall nutritional quality of a drink.
What should I check if PKU applies?
Check the exact product's ingredients for aspartame or E951 and read any phenylalanine warning. Sainsbury's lists aspartame in Sprite Zero Sugar 2L; do not assume another flavour or pack has the same formulation.
How do I compare regular and diet lemonade?
Compare sugars per 100ml on the nutrition panels, then read the ingredients for sweeteners. A regular drink can contain both sugar and sweeteners: ASDA Groceries lists 2.4g sugars per 100ml for its R. White's regular lemonade cans.
How long will an opened diet lemonade bottle keep?
Follow the instructions on the bottle you buy. The ASDA Diet Lemonade 2 Litres and M&S Diet Lemonade product instructions say to refrigerate after opening and consume within three days.
