People with diabetes choosing an everyday fizzy drink
Compare sugars in the amount you expect to drink. A diet or no-added-sugar name alone does not give you the serving figure.
Who needs to check the label?
People who need to plan for hypos
Keep an everyday low-sugar drink separate from the fast-acting carbohydrate specified in your diabetes care plan. Diabetes UK identifies sugary, non-diet drinks as one possible source for treating a hypo; diet lemonade does not serve that purpose.
Shoppers checking sweeteners
Read the ingredients as well as the nutrition panel. This is particularly important if you need to avoid aspartame because of phenylketonuria (PKU).
What matters when choosing lemonade?
Start with sugars for the portion you will drink, then check ingredients and whether the drink is intended for everyday refreshment or kept for a hypo under your care plan.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars per serving | Read sugars per serving and per 100ml, noting the container size. Tesco lists less than 0.1g sugars per 330ml can for its Diet Lemonade, but 9.4g per 330ml can for its regular Lemonade. | I want a fizzy lemon drink for routine use, so the sugar figure for the amount I drink matters more than the word “diet” or the presence of a sweetener. |
| Everyday use or hypo | Distinguish a sugar-free drink from a source of fast-acting carbohydrate. Diabetes UK says a sugary, non-diet drink can be one option for treating a hypo when it provides the amount required by the person’s care plan. | If I need to plan for hypos, I cannot rely on diet or zero-sugar lemonade as my treatment. |
| Ingredients | Check the current ingredients for the sweeteners used, particularly aspartame if PKU is relevant. Compare the exact drink and pack rather than assuming all diet lemonades use the same recipe. | Sweetener choice matters to me, or I need to avoid an ingredient, so I read beyond the front label. |
| Fizzy-drink habits | Consider how often you drink fizzy lemonade, not just its sugar figure. The NHS associates carbonated drinks with dental erosion whether or not they contain sugar. | I may choose a lower-sugar fizzy drink, but I do not want to treat “zero sugar” as meaning no concern for my teeth. |
Mistakes to avoid
-
Assuming a sweetener means the drink has little sugar
Tesco lists sucralose among the ingredients of its regular Lemonade, alongside 9.4g sugars per 330ml can.
Use the sugars line for the portion you will drink, rather than the ingredients list alone, to compare regular and diet versions.
-
Using diet lemonade for a hypo
Diet and zero-sugar lemonade do not provide the fast-acting carbohydrate needed for hypo treatment, according to Diabetes UK.
Follow your diabetes care plan for an appropriate treatment instead of relying on an everyday low-sugar drink.
-
Assuming zero sugar removes the dental concern
The NHS associates carbonated drinks with dental erosion regardless of whether they contain sugar.
Take drinking frequency into account when choosing a fizzy drink; a lower sugar figure does not address that concern.
-
Relying on an older online label
Recipes and nutrition information can change, which matters when you are comparing sugars or avoiding a particular ingredient.
Check the nutrition panel and ingredients on the pack you are buying.
Brand and retailer examples
These examples show why the exact variety and serving size matter; a brand name alone does not identify a drink’s sugar content.
R. White's
A traditional lemonade brand with a Diet Lemonade multipack listed by Tesco.
- Tesco lists 0g sugars per 330ml can for R. White's Diet Lemonade.
- Its listed ingredients include aspartame, acesulfame K and saccharin; check the current pack if sweeteners matter to you.
Sprite
Sprite Zero is a lemon-and-lime soft drink rather than a traditional lemonade.
- Coca-Cola GB lists 0g sugars per 100ml for Sprite Zero.
- Check the ingredients if you need to avoid aspartame, and choose it only if lemon-and-lime flavour suits you.
Tesco
Its diet and regular lemonades provide a direct illustration of why the variety name matters.
- Tesco lists less than 0.1g sugars per 330ml can for Diet Lemonade.
- Its regular Lemonade lists 9.4g sugars per 330ml can, despite also containing a sweetener.
M&S
Its Diet Lemonade is a 2-litre bottled option.
- M&S lists less than 0.1g sugars per 100g for Diet Lemonade.
- That figure is stated per 100g, rather than per glass; check the current bottle for ingredients and the amount you pour.

Common questions
Can someone with diabetes choose diet lemonade for an everyday drink?
A diet lemonade can be a lower-sugar fizzy option when its current nutrition panel confirms the sugars in the amount you will drink. Diabetes UK includes sugar-free soft drinks among drinks that count towards fluid intake, while identifying water as the all-round choice.
Can diet lemonade be used to treat a hypo?
No. Diet or zero-sugar lemonade does not supply the fast-acting carbohydrate needed for a hypo. Diabetes UK identifies sugary, non-diet drinks as one possible source; follow your own diabetes care plan for treatment.
Does “no added sugar” mean zero sugar?
No. Read the sugars figure on the nutrition panel rather than treating that phrase as a zero-sugar value. Tesco lists less than 0.1g sugars per 330ml can for its Diet Lemonade, while M&S lists less than 0.1g per 100g for its Diet Lemonade; the measures differ, so check the portion you will drink.
What should I check if I need to avoid aspartame?
Read the ingredients on the exact pack before buying. Aspartame is unsuitable for people with phenylketonuria (PKU), and sweetener ingredients can differ between drinks.
Does zero-sugar lemonade remove the dental erosion concern?
No. The NHS associates carbonated drinks with dental erosion regardless of whether they contain sugar, so the sugar figure alone does not settle this question.
