Families comparing sugar content
If several people drink fizzy drinks, compare sugars per 100ml across the exact variants you plan to buy. A zero-sugar name does not tell you whether a drink contains caffeine or carries an ingredient warning.
Who is this shop for?
Households shopping for children
Keep the children’s everyday drinks separate from an occasional fizzy-drink purchase. The NHS identifies water and milk as the preferred drinks for children, while Lancashire and South Cumbria Integrated Care Board notes that even diet fizzy drinks can wear away tooth enamel.
Households with caffeine or individual dietary needs
A clearly labelled caffeine-free variant helps when someone wants to avoid caffeine. If a person with diabetes follows a plan for treating a hypo, keep that plan in mind too: Diabetes UK notes that sugary drinks are necessary for some people in that situation.
What should you check first?
Choose the drink variant for the people who will have it, then decide whether shared bottles or individual cans fit how the household will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar content | Compare “of which sugars” per 100ml on the exact variant. PepsiCo UK lists 0g per 100ml for Pepsi Max and 4.5g per 100ml for regular Pepsi; the names are not interchangeable nutrition information. | I want to reduce the sugar in the fizzy drinks bought for the household without assuming a familiar brand or flavour tells me the amount. |
| Children’s drinks | Separate everyday drinks from fizzy-drink purchases. The NHS identifies water and milk as the preferred drinks for children; Lancashire and South Cumbria Integrated Care Board notes that acidic diet fizzy drinks can wear away enamel. | For the children, I need an everyday drink choice as well as a decision about whether to buy fizzy drinks. |
| Caffeine and ingredients | Check for a caffeine-free label and read the ingredients on the exact pack. PepsiCo UK lists Pepsi Max Caffeine Free at 0g sugars per 100ml, while its regular Pepsi Max ingredient information includes caffeine. Check any phenylalanine warning where relevant. | Someone in the household avoids caffeine, or needs to check a particular ingredient warning before sharing a multipack. |
| Pack format | Check bottle volume or can size, the number of units and where the pack will be stored. Match a shared bottle or individually portioned cans to how the household expects to use them. | I need enough for the planned occasions, without choosing a larger format solely because it looks convenient in the shop. |
Common buying mistakes
-
Treating “zero sugar” as a verdict on the whole drink
A zero-sugar label describes sugar content, not dental effects. Lancashire and South Cumbria Integrated Care Board notes that acid in diet fizzy drinks can wear away enamel.
For children’s everyday drinks, start with the NHS-preferred choices of water and milk rather than treating diet fizzy drinks as tooth-neutral.
-
Assuming regular and zero-sugar variants match
Variants from the same range can have different sugar figures. PepsiCo UK lists 4.5g sugars per 100ml for regular Pepsi and 0g per 100ml for Pepsi Max.
Read “of which sugars” per 100ml on the precise flavour and variant you are buying.
-
Assuming every zero-sugar cola is caffeine free
PepsiCo UK lists caffeine among regular Pepsi Max ingredients but offers a separate Pepsi Max Caffeine Free variant.
When caffeine avoidance matters, choose a product explicitly labelled caffeine free and check its ingredient list.
Brand and retailer references
These ranges illustrate why the exact variant matters; a brand name alone does not establish its sugar content or ingredients.
Coca-Cola
Its UK cola range includes Coca-Cola Zero Sugar.
- Coca-Cola Great Britain lists 0g sugars per 100ml for Coca-Cola Zero Sugar.
- Its product information lists caffeine flavouring and a source of phenylalanine; check the exact pack if either matters.
Pepsi
The UK range includes regular Pepsi, Pepsi Max and Pepsi Max Caffeine Free.
- PepsiCo UK lists 0g sugars per 100ml for Pepsi Max and Pepsi Max Caffeine Free.
- Regular Pepsi lists 4.5g sugars per 100ml. Regular Pepsi Max includes caffeine, so check which variant is in the pack.
Sprite
The lemon-and-lime range includes Sprite Zero.
- Coca-Cola Great Britain lists 0g sugars per 100ml for Sprite Zero.
- Check its sweeteners and phenylalanine warning on the exact pack where relevant.
Fanta
Flavours and variants in this range have different sugar figures.
- Coca-Cola Great Britain lists 4.5g sugars per 100ml for Fanta Orange and 0.4g per 100ml for Fanta Fruit Twist Zero.
- Check the flavour and variant rather than applying either figure to the whole Fanta range.
Dr Pepper
Standard and Zero variants appear as separate products in Tesco Groceries’ UK fizzy-drink cans category.
- The category lists a Dr Pepper Zero 8 x 330ml pack.
- Check the nutrition and ingredients of the precise pack; the variant name does not describe every Dr Pepper product.
Tesco
The retailer’s fizzy-drink category includes own-label and branded options.
- Tesco Groceries lists Tesco Diet Lemonade 6 x 330ml alongside branded zero-sugar cans.
- Check each product’s variant, pack size and label separately; a retailer category is not a shared nutrition specification.

Questions about family fizzy-drink choices
Are zero-sugar fizzy drinks suitable as children’s everyday drinks?
Choose water or milk as the everyday drinks for children: these are the NHS-preferred options. Zero sugar does not remove acidity; Lancashire and South Cumbria Integrated Care Board notes that diet fizzy drinks can wear away tooth enamel.
Can one diet fizzy-drink choice cover everyone in a household with diabetes?
Do not use one rule for every situation. Diabetes UK notes that sugary drinks or glucose tablets are essential for some people when treating a hypo, so follow the individual’s care plan rather than substituting a diet drink in that situation.
How can I choose a fizzy drink when someone avoids caffeine?
Look for a specifically labelled caffeine-free variant and check its ingredients. PepsiCo UK lists Pepsi Max Caffeine Free as a separate product from Pepsi Max, whose ingredient information includes caffeine.
Why check for a phenylalanine warning on zero-sugar drinks?
Some variants carry a “contains a source of phenylalanine” warning: the UK product information for Coca-Cola Zero Sugar and Pepsi Max includes one. If someone follows dietary advice relating to phenylalanine, check the exact pack and their individual guidance before choosing it.
