Who is choosing the drink?

Parents packing an occasional fizzy drink

Check the sugars on the specific pack without making fizzy drinks the routine school-day choice. St George’s University Hospitals NHS Foundation Trust advises water or plain milk between meals.

Families avoiding caffeine

Look for a specifically caffeine-free variant rather than assuming every zero-sugar cola is caffeine-free. Standard Coca-Cola Zero Sugar and Pepsi Max list caffeine, while their named caffeine-free alternatives are separate products.

Children choosing between cola and fruit flavours

Flavour can narrow the choice, but the full variant name and nutrition panel determine whether a drink meets a 0g-sugars-per-100ml aim. A familiar brand name alone does not identify the sugar content.

What should you check first?

Start with when the drink will be used, then compare the exact variant’s sugars, caffeine designation and ingredients.

PriorityWhat to checkYour needs
Drinking occasion Decide whether this is an occasional fizzy drink or the usual drink between meals. Sugar-free fizz is still acidic; Northumbria Healthcare NHS Foundation Trust says it can cause tooth erosion. For an everyday school drink, I would choose water or plain milk. If I am packing fizzy drink occasionally, I do not want it sipped throughout the day.
Sugars per 100ml Read ‘of which sugars’ for the exact flavour and pack. If the aim is 0g, look for 0g per 100ml rather than relying on ‘no added sugar’ or ‘zero’ alone. I want to know the finished drink’s sugar content, not just whether sugar was added. Coca-Cola GB lists Fanta Fruit Twist Zero at 0.4g sugars per 100ml, so the exact figure matters.
Caffeine Check for ‘No Caffeine’, ‘Zero Caffeine’ or a caffeine-free designation, then read the ingredients. Coca-Cola GB and Pepsi UK distinguish their standard zero-sugar colas from caffeine-free variants. If I want to avoid caffeine in a school-day drink, a standard zero-sugar cola does not meet that preference just because it has 0g sugars.
Flavour Compare cola with lemon-and-lime or fruit-flavoured variants, then recheck sugars and caffeine for the chosen product. Coca-Cola GB identifies Sprite Zero Sugar and Fanta Zero Sugar drinks as caffeine-free. A child may prefer a fruit flavour to cola, but I still need to check the particular variant rather than assume a whole range has the same nutrition.
Sweeteners and warnings Read the ingredients and any phenylalanine notice on the exact can or bottle. The cited Coca-Cola GB and Pepsi UK product information lists sweeteners for several zero-sugar variants. If an ingredient or label warning matters to the person drinking it, I need that product’s label—not the details of another flavour or pack.

Common buying mistakes

  • Reading ‘no added sugar’ as ‘0g sugars’

    The wording concerns what has been added; it does not state the finished drink’s total sugars. Coca-Cola GB, for example, lists 0.4g sugars per 100ml for Fanta Fruit Twist Zero.

    If 0g is your aim, check ‘of which sugars’ per 100ml on the exact variant.

  • Assuming zero-sugar cola has no caffeine

    Coca-Cola GB lists caffeine flavouring in standard Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in Pepsi Max. Their caffeine-free versions are separately named.

    Choose a product explicitly identified as caffeine-free and check its current ingredients.

  • Using sugar-free fizz as the between-meal drink

    Northumbria Healthcare NHS Foundation Trust notes that sugar-free fizzy drinks remain acidic and can cause tooth erosion.

    For a routine drink between meals, follow St George’s University Hospitals NHS Foundation Trust’s advice to offer water or plain milk; keep fizzy drinks occasional.

  • Choosing by brand or flavour name alone

    A brand range can contain both standard and zero-sugar versions. The logo does not identify the sugars in the particular drink being bought.

    Match the full variant name to its nutrition panel before choosing a pack.

Brand and range references

These examples show why the variant matters; a brand name does not, by itself, confirm sugars, caffeine or ingredients.

Coca-Cola

Coca-Cola GB lists standard Coca-Cola Zero Sugar and a separate Coca-Cola Zero Sugar Zero Caffeine variant.

  • Both are listed at 0g sugars per 100ml by Coca-Cola GB.
  • The standard variant lists caffeine flavouring; the cited product information also lists sweeteners and a phenylalanine notice.

Pepsi

Pepsi UK distinguishes Pepsi Max from Pepsi Max No Caffeine for shoppers comparing cola variants.

  • Pepsi UK lists 0g sugars per 100ml for both cited variants.
  • Standard Pepsi Max lists caffeine. Check the exact variant’s sweeteners and phenylalanine notice.

Sprite

Sprite Zero Sugar is a lemon-and-lime alternative to cola; Coca-Cola GB lists it among its caffeine-free drinks.

  • Coca-Cola GB lists 0g sugars per 100ml for Sprite Zero Sugar.
  • Its listed ingredients include acids and sweeteners, so check the product label if either matters to your choice.

Fanta

Coca-Cola GB lists Fanta Zero Sugar drinks among its caffeine-free options for shoppers who prefer fruit flavours.

  • The range offers a fruit-flavoured alternative to cola.
  • Coca-Cola GB lists Fanta Fruit Twist Zero at 0.4g sugars per 100ml. Check the exact flavour if your aim is 0g.

Dr Pepper

Dr Pepper Zero is a differently flavoured zero-sugar option for shoppers considering an alternative to standard cola.

  • Coca-Cola GB lists 0g sugars per 100ml for Dr Pepper Zero.
  • Its listed flavourings include caffeine, so it does not meet a caffeine-free preference.

Tesco

Tesco lists its own-label Xero Cola alongside branded sugar-free colas in its grocery range.

  • Tesco describes Xero Cola as a sugar-free carbonated cola drink.
  • Tesco’s product description identifies caffeine and sweeteners. Check the current pack for its exact nutrition and ingredients.

Questions about school-day choices

Does ‘no added sugar’ mean the drink has 0g sugars?

No. The wording concerns added sugar, not necessarily all sugars in the finished drink. Check ‘of which sugars’ per 100ml on the exact variant: Coca-Cola GB lists 0g for Sprite Zero Sugar but 0.4g for Fanta Fruit Twist Zero.

Which named zero-sugar options are caffeine-free?

Coca-Cola GB identifies Coca-Cola Zero Sugar Zero Caffeine and Sprite Zero Sugar as caffeine-free, and Pepsi UK identifies Pepsi Max No Caffeine as caffeine-free. Coca-Cola GB also lists Fanta Zero Sugar drinks among its caffeine-free options. Check the current pack for the particular variant you choose.

Should a sugar-free fizzy drink be the usual drink between meals?

For a routine between-meal drink, St George’s University Hospitals NHS Foundation Trust advises water or plain milk. Northumbria Healthcare NHS Foundation Trust notes that sugar-free fizz remains acidic and can cause tooth erosion, so removing sugar does not remove that consideration.

Why does a zero-sugar drink mention phenylalanine?

Several of the cited Coca-Cola GB and Pepsi UK variants list aspartame and carry a ‘contains a source of phenylalanine’ notice. If that warning is relevant to the person drinking it, review the ingredients and notice on the exact pack.
