Commuters reducing sugar
A 330ml can is easy to take with breakfast, but a diet or zero-sugar name does not tell you everything about the drink. Compare sugars and energy for the whole can you plan to drink.
Who is choosing?
People avoiding caffeine
Check the exact variant rather than relying on its cola or zero-sugar name. Tesco lists caffeine in Pepsi MAX 330ml, while its separate Pepsi MAX No Caffeine listing explicitly says it contains no caffeine.
Households considering children’s drinks and teeth
NHS guidance associates carbonated drinks with dental erosion regardless of sugar content. It also says fizzy drinks should not be given to babies and young children, and does not recommend diet or reduced-sugar drinks for them.
What should you check?
Start with the nutrition panel for the portion you will drink, then check ingredients and whether a fizzy drink suits the occasion at all.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars and energy | Read sugars and energy per can, not just per 100ml. Check the serving size and the nutrition panel alongside any zero-sugar wording. | I want a breakfast add-on that does not add the sugars in a standard sugary fizzy drink. A front-of-pack name alone is not enough for my choice. |
| Caffeine | Look for an explicit caffeine-free statement and check the ingredients of the exact variant. Tesco lists caffeine in Pepsi MAX 330ml but describes Pepsi MAX No Caffeine as caffeine-free. | If I avoid caffeine, a zero-sugar cola is only an option once I have checked which version it is. |
| Sweeteners | Read the ingredients for particular sweeteners. NHS guidance says aspartame is unsuitable for people with phenylketonuria (PKU) because it contains phenylalanine. | I need to check the exact label if PKU or another ingredient restriction affects my choice. |
| Acidity and age | Do not use zero sugar as a measure of dental impact. The NHS associates carbonated drinks with dental erosion and advises against fizzy drinks for babies and young children. | For a child’s drink, or when avoiding acidic drinks matters, I would choose something other than fizzy pop. |
| Can and pack size | Compare the can size with the nutrition serving size. For a multipack, check that its exact drink variant meets your ingredient requirements. | A single can is easier to assess as one breakfast portion; before choosing a multipack, I want to know that I like the flavour and have checked its label. |
Common buying mistakes
-
Taking “zero sugar” to mean tooth-friendly
NHS guidance associates carbonated drinks with dental erosion because of their acid content, whether or not they contain sugar.
If avoiding acidic drinks is important, choose water or plain milk rather than relying on a zero-sugar label.
-
Assuming every zero-sugar drink is caffeine-free
Tesco lists caffeine in Pepsi MAX 330ml and describes the separately named Pepsi MAX No Caffeine as caffeine-free.
Check for an explicit caffeine-free statement and read the ingredients on the exact drink you are buying.
-
Checking the name but not the nutrition panel
Tesco lists 1.3g sugars per 330ml can of Fanta Orange Zero, while its listings for Sprite Zero Sugar and Pepsi MAX 330ml state 0g sugars per can.
Compare sugars, energy and serving size on the exact can or bottle rather than assuming similarly named drinks have identical values.
Brand and product-line references
These examples distinguish particular drinks and variants; a brand name alone does not establish the nutrition or caffeine content of every product it sells.
Coca-Cola
Coca-Cola Zero Sugar is a cola option for shoppers looking at a 330ml can.
- Tesco describes its 330ml Coca-Cola Zero Sugar listing as zero sugar and zero calories.
- For a caffeine or ingredient restriction, check the exact pack. Zero sugar does not remove the NHS dental-erosion consideration for carbonated drinks.
Pepsi
Pepsi MAX and Pepsi MAX No Caffeine are distinct cola choices when caffeine matters.
- Tesco lists 0g sugars per 330ml can for both variants and describes Pepsi MAX No Caffeine as caffeine-free.
- Tesco lists caffeine in standard Pepsi MAX. Check the exact ingredients if a particular sweetener or phenylalanine warning matters.
Sprite
Sprite Zero Sugar offers a lemon-and-lime alternative to cola.
- Tesco lists 0g sugars and 3 kcal per 330ml can of Sprite Zero Sugar.
- It is still a carbonated drink; NHS guidance associates carbonated drinks with dental erosion regardless of sugar content.
Fanta
Fanta Orange Zero is a fruity option that Tesco describes as caffeine-free.
- Tesco lists 1.3g sugars per 330ml can of Fanta Orange Zero.
- Its Zero name should not replace checking the nutrition panel when the amount of sugar matters to you.
Dr Pepper
Dr Pepper Zero is a separately named fizzy-drink option.
- Tesco describes Dr Pepper Zero as zero sugar and zero calories.
- Check the exact pack’s nutrition, caffeine and ingredients information before using it to meet a specific dietary requirement.

Frequently asked questions
Does a zero-sugar fizzy drink make sense with breakfast?
It can be a swap when reducing free sugars is your reason for choosing between fizzy drinks. NHS guidance includes sugar-free or diet drinks as alternatives to sugary fizzy drinks, but their sugar content does not remove the dental-erosion consideration associated with carbonation.
Does zero sugar mean a fizzy drink is better for teeth?
No. The NHS associates carbonated drinks with dental erosion because of their acid content, regardless of whether they contain sugar or sweeteners. If avoiding acidic drinks is the priority, consider water or plain milk instead.
Which of these drink variants are described as caffeine-free?
Tesco describes Pepsi MAX No Caffeine and Fanta Orange Zero as caffeine-free. Its Pepsi MAX 330ml ingredients include caffeine, so check the exact variant rather than assuming a zero-sugar drink is caffeine-free.
Are diet fizzy drinks suitable for babies and young children?
NHS guidance says fizzy drinks should not be given to babies and young children because they are acidic and can damage tooth enamel. It also does not recommend diet or reduced-sugar drinks for them.
Why check sweeteners if you have PKU?
The NHS says aspartame is unsuitable for people with phenylketonuria (PKU) because it contains phenylalanine. Read the exact drink’s ingredients and warnings: a zero-sugar name does not identify which sweeteners it contains.
