Adults looking to reduce sugar
If you want fizz with a quick breakfast but not a regular sugary cola, compare sugars per can or bottle. Then check caffeine separately: a zero-sugar label does not answer both questions.
Who is choosing?
People avoiding caffeine
Look for an explicitly caffeine-free variant if you still want a cola-style drink. Coca-Cola Zero Sugar and standard Pepsi Max list caffeine, whereas Pepsi UK describes Pepsi Max Caffeine-Free as having none.
Parents choosing a child’s breakfast drink
The NHS advises that children avoid sugary fizzy drinks completely. Convenience alone is not a reason to make one the usual breakfast drink.
What should you check?
Start with the amount you would actually drink, then check caffeine and ingredients on the exact variant. If you are choosing for a child, the NHS advice on sugary fizzy drinks changes the decision.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars per drink | Compare sugars per 100ml and per full can or bottle. Joybuy lists 35g sugars per 330ml can of Coca-Cola Original Taste; Coca-Cola GB lists 0g per 100ml for Coca-Cola Zero Sugar. The NHS advises adults to have no more than 30g free sugars a day. | “I’m picking up one drink with breakfast and want to know how much sugar that whole serving contains.” |
| Caffeine | Check the named variant and its ingredients. Coca-Cola Zero Sugar and Pepsi Max list caffeine; Pepsi UK describes Pepsi Max Caffeine-Free as having no caffeine and 0g sugars per 330ml. | “I’d like cola flavour, but I also want to avoid caffeine.” A zero-sugar label alone will not settle that choice. |
| Sweeteners | Read the ingredients and any phenylalanine statement on the pack. Coca-Cola GB and Pepsi UK list aspartame in named zero-sugar colas; GOV.UK guidance specifies the phenylalanine label statement when aspartame is named in the ingredients. | “I want to know which sweeteners are in this particular drink before putting it in my bag.” |
| Flavour and format | Choose between cola, fruit-flavoured fizz and flavoured sparkling water by checking the exact product. Coca-Cola GB describes Fanta Orange as caffeine-free; Tesco describes its Apple & Raspberry sparkling flavoured water as no added sugar and made with sweetener. | “Cola isn’t what I fancy this morning, but I still want something sparkling.” I would check sugar and caffeine on the alternative rather than infer them from its flavour. |
| Children’s drinks | The NHS advises that children avoid sugary fizzy drinks completely. Do not use an adult’s breakfast-time preference as the basis for a child’s drink choice. | “I’m packing breakfast for a child and want a convenient drink without making sugary fizz the default.” |
Common label mistakes
-
Checking only the per-100ml sugar figure
A full can may contain considerably more than the per-100ml figure suggests at a glance. Joybuy lists 35g sugars in a 330ml can of Coca-Cola Original Taste, above the NHS adult daily free-sugars guideline of 30g.
Compare the sugars figure for the whole can or bottle you intend to drink, especially when choosing a multipack.
-
Assuming zero sugar means caffeine-free
Coca-Cola Zero Sugar and Pepsi Max list caffeine, while Pepsi UK identifies Pepsi Max Caffeine-Free as a separate variant.
If you want to avoid caffeine, look for an explicit caffeine-free designation and check the ingredients on the exact pack.
-
Overlooking the ingredients on a zero-sugar drink
Named zero-sugar colas contain sweeteners including aspartame. GOV.UK guidance specifies a “Contains a source of phenylalanine” statement when aspartame is named in the ingredients.
Read the full ingredients and label statements rather than relying only on the front-of-pack sugar claim.
-
Making sugary fizz a child’s routine breakfast drink
The NHS advises that children avoid sugary fizzy drinks completely.
Choose a child’s breakfast drink with that guidance in mind, rather than selecting sugary fizz for convenience.
Relevant drink ranges
These named drinks illustrate different label choices; a brand name alone does not establish the ingredients of every variant.
Coca-Cola
Coca-Cola GB lists Original Taste at 10.6g sugars per 100ml and Coca-Cola Zero Sugar at 0g sugars per 100ml.
- The two named variants give a clear regular-versus-zero-sugar label comparison.
- Zero Sugar lists caffeine and sweeteners, including aspartame; Original Taste contains sugar.
Pepsi
Pepsi UK lists 0g sugars per 330ml for both Pepsi Max and Pepsi Max Caffeine-Free.
- The named Caffeine-Free variant offers a cola option when avoiding both sugar and caffeine matters.
- Standard Pepsi Max lists caffeine. Check the sweeteners and phenylalanine statement on the variant you choose.
Fanta
Coca-Cola GB describes Fanta Orange as a caffeine-free, fruit-flavoured fizzy drink.
- Fanta Orange is a named alternative for someone seeking fruit flavour without caffeine.
- Caffeine-free does not mean sugar-free; check the nutrition panel on the exact pack.
Sprite
Tesco lists Sprite Zero Sugar as a lemon-and-lime fizzy drink with no sugar.
- The named variant offers a citrus-flavoured zero-sugar option.
- Check the purchased pack’s ingredients if caffeine or particular sweeteners matter to you.
Dr Pepper
Ocado describes Dr Pepper Zero as a sparkling fruit-flavour soft drink with sweeteners and zero sugar.
- The named Zero variant offers another fruit-flavoured, zero-sugar choice.
- Check the current can for its ingredients and caffeine information.
Tesco
Tesco describes its Apple & Raspberry sparkling flavoured water as carbonated, with no added sugar and with sweetener.
- The named drink offers a flavoured sparkling-water option rather than a cola-style drink.
- No added sugar does not mean plain, unsweetened water; check the exact ingredients and nutrition label.

Questions about breakfast-time fizz
Can a fizzy drink replace breakfast?
No: choose it, if you want one, as a drink alongside food rather than as breakfast itself. For routine drinking, the NHS recommends swapping sugary drinks for diet, sugar-free or no-added-sugar alternatives.
What should I check first on the label?
Check sugars for the full can or bottle, then look for caffeine in the ingredients or an explicit caffeine-free designation. If you are considering a zero-sugar drink, read its sweeteners and any phenylalanine statement too.
Are zero-sugar fizzy drinks caffeine-free?
Not necessarily. Coca-Cola Zero Sugar and Pepsi Max list caffeine, while Pepsi UK describes Pepsi Max Caffeine-Free as having none. Choose the named caffeine-free variant and check its current label if avoiding caffeine is important.
What does “contains a source of phenylalanine” mean?
It is a label statement associated with aspartame: GOV.UK guidance specifies it when aspartame is named in the ingredients. Read the statement and ingredient list on the exact zero-sugar drink you are considering.
Should I choose a sugary fizzy drink for a child’s breakfast?
The NHS advises that children avoid sugary fizzy drinks completely. Do not make one the routine breakfast choice simply because a can is convenient to carry.
