Regular breakfast fizzy-drink buyers
If a fizzy drink is becoming part of your weekday routine, its sugar content, caffeine and acidity are worth checking alongside flavour.
Who is this choice for?
Cola drinkers avoiding caffeine
If you want cola with breakfast but are limiting caffeine, compare the named variants rather than relying on a zero-sugar label. NHS guidance also sets a daily caffeine limit for pregnant people.
Shoppers comparing flavoured options
If you prefer cola, lemon-and-lime or fruit flavours, compare the regular and zero-sugar versions of the exact drink you plan to buy.
What should you check?
Decide whether plain sparkling water meets the need for fizz, then compare the label on any flavoured drink you are considering.
| Priority | What to check | Your needs |
|---|---|---|
| Drink type | Choose between plain sparkling water and a flavoured fizzy drink. Check the exact flavour and variant if you want sweetness. | I want some fizz with breakfast, but I do not necessarily want a sweet drink. |
| Sugars | Compare sugars per 100ml on the exact pack, then consider how much you will drink. Coca-Cola Great Britain lists 10.6g per 100ml for Coca-Cola Original Taste and 4.4g per 100ml for Sprite; their variants differ. | If I have a flavoured drink on most weekdays, I want to know whether the one I choose contains sugar rather than judge it by brand name. |
| Caffeine | Check the variant name and ingredients for caffeine or explicit caffeine-free wording. The NHS advises pregnant people not to exceed 200mg of caffeine a day from all sources. | Tea or coffee may already be part of my morning, so I need to know whether a cola adds caffeine. |
| Teeth | Consider how often you drink fizzy drinks, not just their sugar content. Queen Victoria Hospital NHS Foundation Trust advises limiting fizzy drinks because they can be acidic; sugary versions also raise tooth-decay concerns. | I want to avoid treating a zero-sugar fizzy drink as interchangeable with water for a daily routine. |
| Ingredients | Read the sweetener list and any phenylalanine statement on the precise variant. Coca-Cola Great Britain, PepsiCo and Sprite product information identifies a source of phenylalanine in several named zero-sugar drinks. | If an ingredient matters to me, I need to check this pack rather than assume all zero-sugar recipes are alike. |
Common buying mistakes
-
Assuming zero sugar means caffeine-free
PepsiCo lists caffeine in standard Pepsi Max, while Pepsi Max No Caffeine is a separate variant.
Check caffeine-free wording and the ingredients on the exact drink you intend to buy, especially if you monitor caffeine from other drinks.
-
Assuming sugar-free means no dental consideration
Queen Victoria Hospital NHS Foundation Trust notes that fizzy drinks can be acidic; removing sugar does not make a fizzy drink the same choice as water for teeth.
Consider how often you drink it, and use water as your routine hydration choice.
-
Comparing brands without checking variants
A brand may offer regular, zero-sugar and caffeine-free drinks with different ingredients.
Compare sugars per 100ml, caffeine wording, ingredients and pack size for the precise flavour and format.
Brand and retailer references
Coca-Cola
The Great Britain range includes Coca-Cola Original Taste and named zero-sugar and caffeine-free variants.
- Coca-Cola Great Britain lists 10.6g sugars per 100ml for Original Taste and 0g per 100ml for Coca-Cola Zero Sugar Caffeine Free.
- Check the exact variant: zero sugar alone does not establish caffeine-free status.
Pepsi
Pepsi Max and Pepsi Max No Caffeine offer a useful variant comparison for cola drinkers.
- PepsiCo lists 0g sugars per 100ml for both named products and identifies the No Caffeine variant separately.
- Standard Pepsi Max lists caffeine in its ingredients. Both named variants state that they contain a source of phenylalanine.
Sprite
A lemon-and-lime option with regular Sprite and Sprite Zero variants.
- Coca-Cola Great Britain lists 4.4g sugars per 100ml for Sprite and 0g per 100ml for Sprite Zero.
- A zero-sugar variant remains a fizzy drink; check its ingredients and consider the acidity of fizzy drinks.
Fanta
A fruit-flavoured range; Tesco Groceries listed Fanta Zero Orange and Fanta Zero Fruit Twist in its fizzy-drinks catalogue.
- Check the nutrition and ingredients of the particular flavour and pack rather than assuming all Fanta variants share a recipe.
Tesco
A retailer and own-label reference when comparing branded drinks with options such as Tesco Diet Lemonade and Tesco Lemon & Lime Zero.
- Check the current product label for the exact own-label or branded drink you choose.

Questions about breakfast fizzy drinks
Does zero sugar make a fizzy drink the same choice as water?
No. A zero-sugar variant differs from a sugary recipe in its listed sugars, but Queen Victoria Hospital NHS Foundation Trust advises limiting fizzy drinks because they can be acidic. The NHS identifies water as a choice for hydration, including sparkling water if you prefer it to still water.
How do I check whether a zero-sugar cola contains caffeine?
Read the exact variant name and ingredients. PepsiCo lists caffeine in standard Pepsi Max, while Pepsi Max No Caffeine is a distinct product; Coca-Cola also has a named Zero Sugar Caffeine Free variant.
What if I need to avoid phenylalanine?
Check the statement on the exact pack before choosing a zero-sugar drink. Product information from Coca-Cola Great Britain and PepsiCo identifies a source of phenylalanine in named variants including Coca-Cola Zero Sugar Caffeine Free, Pepsi Max and Pepsi Max No Caffeine.
