Snack-drink shoppers watching sugar
If you want a can of cola alongside a gym-bag snack without choosing the sugar listed on regular-cola labels, compare sugars per 100ml. Keep water for replacing fluids lost through activity, as the NHS advises.
Who is choosing this drink?
Cola drinkers avoiding caffeine
Look for a variant explicitly labelled No Caffeine or Zero Caffeine. Coca-Cola Zero Sugar and Pepsi Max list caffeine-containing flavouring, so a zero-sugar label alone does not settle this choice.
Shoppers comparing supermarket and branded cola
Sainsbury's lists own-label Cola and Cola Zero. Compare the exact can or bottle with branded alternatives rather than assuming their sugar, caffeine and ingredients are the same.
What should you check?
Decide whether sugar or caffeine changes your choice, then check the ingredients and pack you would actually take with a snack.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Compare sugars per 100ml on the exact variant. Coca-Cola GB lists 0g for Coca-Cola Zero Sugar and 10.6g for Original Taste; Pepsi UK lists 0g for Pepsi Max and 4.5g for standard Pepsi. | I want cola with a snack, but I would rather choose a zero-sugar variant than the sugar listed on a regular cola. |
| Caffeine | Read the variant name and ingredient list. Coca-Cola Zero Sugar and Pepsi Max list caffeine-containing flavouring; look for a separately labelled No Caffeine or Zero Caffeine version when avoiding it. | A fizzy cola appeals to me, but I want to avoid caffeine, including when I have a snack later in the day. |
| After exercise | Take water for replacing fluid lost through activity. The NHS identifies water as the best way to replace lost fluids; choose cola separately as a snack drink. | After sweating, I need a drink for rehydration as well as something fizzy to have with my snack. |
| Ingredients | Check the exact can for sweeteners and any phenylalanine statement. Do not assume a different flavour or caffeine-free variant has the same ingredient list. | Ingredient labelling matters to me, so I want to inspect the variant I am buying rather than rely on the wider brand name. |
| Pack format | Check can or bottle size and the number in the pack. A 330ml can is one format shown in Tesco's Coca-Cola Zero Sugar listing and among the Joybuy options below. | I want a single can to put beside a gym-bag snack, while choosing a multipack size that suits how I will use it. |
Common buying mistakes
-
Assuming zero sugar means no caffeine
Coca-Cola Zero Sugar and Pepsi Max list caffeine-containing flavouring. Their sugar labels do not tell you that caffeine is absent.
If you want to avoid caffeine, check for No Caffeine or Zero Caffeine on the exact variant and read its ingredients.
-
Using regular cola as the main drink after exercise
For fluid lost through physical activity, the NHS identifies water as the best replacement.
Pack water for after sweating; decide separately whether you want cola alongside your snack.
-
Treating every regular or own-label cola alike
Official labels list 10.6g sugars per 100ml for Coca-Cola Original Taste and 4.5g for standard Pepsi. Those figures cannot be assigned to another brand or variant.
Compare sugars per 100ml, the caffeine information and the serving size on the exact pack before buying.
Brand ranges to compare
Coca-Cola
Its UK range offers Original Taste, Zero Sugar and a separately labelled Zero Sugar Zero Caffeine variant.
- Coca-Cola GB lists 0g sugars per 100ml for Zero Sugar and 10.6g for Original Taste.
- Zero Sugar lists caffeine flavouring; choose the specifically labelled Zero Caffeine variant if caffeine avoidance matters.
Pepsi
Its UK range includes standard Pepsi, Pepsi Max and Pepsi Max No Caffeine.
- Pepsi UK lists 0g sugars per 100ml for Pepsi Max and Pepsi Max No Caffeine, compared with 4.5g for standard Pepsi.
- Pepsi Max lists caffeine-containing flavouring; the separately named No Caffeine version is the relevant choice when avoiding caffeine.
Sainsbury's
Its cola listings include own-label Cola and Cola Zero, giving shoppers another range to examine alongside branded drinks.
- The Sainsbury's category listing distinguishes regular and zero-sugar own-label options.
- Check the individual product label for sugar, caffeine and ingredients rather than applying a branded cola's figures to it.
Tesco
Its grocery listings include branded Coca-Cola Zero Sugar formats, including a 330ml can.
- The Tesco 330ml Coca-Cola Zero Sugar listing identifies a can-sized format and lists 0g sugars.
- A branded product listing does not establish the ingredients of a Tesco own-label cola; compare its own label separately.

Questions about cola and gym-bag snacks
Should cola be my main drink after a gym session?
Take water as your main drink for replacing fluids lost through physical activity; the NHS identifies it as the best way to do so. You can decide separately whether you want cola alongside a snack.
Does zero-sugar cola have no caffeine?
Not necessarily. Coca-Cola Zero Sugar and Pepsi Max list caffeine-containing flavouring. If you want to avoid caffeine, choose a variant expressly labelled Zero Caffeine or No Caffeine and check its ingredients.
How does the sugar on regular-cola labels compare with zero-sugar variants?
Coca-Cola GB lists 0g sugars per 100ml for Coca-Cola Zero Sugar and 10.6g for Original Taste; Pepsi UK lists 0g for Pepsi Max and 4.5g for standard Pepsi. Compare the exact variant rather than applying either regular-cola figure to every brand.
