Parents and carers buying school-day drinks
Compare sugar and caffeine on the exact pack, and distinguish a drink provided by a school from one brought in a packed lunch. NHS oral-health advice also makes the timing of fizzy drinks relevant.
Who is choosing the drink?
Older pupils considering zero-sugar cola
A zero-sugar label answers the sugar question, not the caffeine question. Check both if the drink is intended for a back-to-school occasion.
Households checking phenylalanine information
Some zero-sugar colas contain aspartame and carry a source-of-phenylalanine statement. Anyone who needs to avoid phenylalanine should check the exact product label.
What should you check?
Start with the sugar and caffeine information for the exact variant, then consider when and where the drink will be consumed.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Read sugars per 100ml and for the amount likely to be drunk. Coca-Cola Great Britain lists 10.6g per 100ml for Original Taste; PepsiCo UK lists 15g per 330ml can for Pepsi. The NHS gives maximum recommended daily free-sugar amounts of 24g for ages 7–10 and 30g for ages 11 and over. | I’m comparing regular and zero-sugar cola, so I want to know how much sugar the whole can or bottle contributes, not just the per-100ml figure. |
| Caffeine | Check the exact variant for a caffeine-free or no-caffeine designation. PepsiCo UK lists caffeine in Pepsi Max, but no caffeine in Pepsi Max No Caffeine. | Sugar reduction matters to me, but I also want a cola without caffeine around the school day. |
| Between-meal drinks | Consider when a fizzy drink will be consumed, even if it lists 0g sugars. St George’s University Hospitals NHS Foundation Trust identifies fizzy drinks as an acid-erosion concern and recommends water or plain milk between meals. | I’m choosing a routine drink for between lessons, rather than a cola for an occasional meal or social occasion. |
| Ingredients | Read the sweeteners and any source-of-phenylalanine statement on the exact pack. Coca-Cola Great Britain lists aspartame in Coca-Cola Zero Sugar Zero Caffeine; PepsiCo UK identifies a source of phenylalanine on Pepsi Max No Caffeine. | If phenylalanine must be avoided in my household, the word “diet” or “zero” alone does not answer the ingredient question. |
| School rules | For a drink supplied by a state-funded school in England, distinguish the School Food Standards from the individual school’s packed-lunch guidance. The Department for Education’s published list of permitted school-provided drink categories does not include cola. | I’m buying for a lunchbox, so I need to check that school’s packed-lunch rules rather than assume rules for school-provided drinks settle the question. |
Common mix-ups
-
Reading “zero sugar” as “caffeine-free”
PepsiCo UK lists caffeine in Pepsi Max, although it lists 0g sugars. The two claims describe different things.
If avoiding caffeine matters, look for “No Caffeine” or “Caffeine Free” on the exact variant and check its ingredients.
-
Treating zero-sugar cola as a between-meal drink
Removing sugar does not remove the acid-erosion concern associated with fizzy drinks in St George’s University Hospitals NHS Foundation Trust oral-health advice.
For between meals, that NHS advice recommends water or plain milk. If choosing cola for another occasion, consider when it will be drunk rather than sipping it throughout the day.
-
Comparing only per-100ml sugar figures
A can or bottle may contain more than 100ml, so its total sugar amount differs from the figure on that basis.
Check the amount actually consumed and compare its sugar figure with the relevant NHS daily free-sugar guidance: 24g for ages 7–10 or 30g for ages 11 and over.
-
Applying school-provided drink rules to every lunchbox
England’s School Food Standards address food and drink provided by schools; they do not, by themselves, set an individual school’s packed-lunch policy.
Check the school’s packed-lunch guidance before buying cola specifically for a lunchbox.
Brand and retailer references
Coca-Cola
Its named UK variants illustrate the difference between regular cola and a zero-sugar, caffeine-free cola.
- Coca-Cola Great Britain lists 10.6g sugars per 100ml for Original Taste and 0g sugars with no caffeine for Coca-Cola Zero Sugar Zero Caffeine.
- Coca-Cola Zero Sugar Zero Caffeine lists aspartame among its sweeteners; check the exact pack if phenylalanine information matters.
Pepsi
PepsiCo UK lists regular Pepsi, zero-sugar Pepsi Max and Pepsi Max No Caffeine as distinct choices.
- PepsiCo UK lists 15g sugars per 330ml can for Pepsi and 0g sugars for the named Pepsi Max variants.
- Standard Pepsi Max contains caffeine. Pepsi Max No Caffeine is a different variant and carries a source-of-phenylalanine statement.
Tesco
Tesco’s caffeine-free cola category listed its own-label Caffeine Free Diet Cola alongside branded alternatives.
- The category offers a way to compare named caffeine-free variants and pack formats.
- Check the individual product label for sugars, ingredients and pack size; a category listing does not establish those details for every variant.

Frequently asked questions
Does zero-sugar cola make a better between-meal drink than regular cola?
Zero-sugar cola changes the sugar comparison, but it does not remove the concern about fizzy drinks and acid erosion. St George’s University Hospitals NHS Foundation Trust recommends water or plain milk between meals. For sugar figures, Coca-Cola Great Britain lists 0g sugars for Coca-Cola Zero Sugar Zero Caffeine and 10.6g per 100ml for Original Taste.
Does “zero sugar” also mean caffeine-free?
No. PepsiCo UK lists 0g sugars in Pepsi Max but includes caffeine in its ingredients. If caffeine avoidance matters, choose an explicitly labelled caffeine-free or no-caffeine variant and check the exact pack.
Can a state-funded school in England provide cola?
Cola is not among the permitted school-provided drink categories listed in the Department for Education’s account of England’s School Food Standards; the Department also states that compliance is a legal requirement for state-funded schools. This does not, by itself, decide what a pupil may bring in a packed lunch, so check the school’s own packed-lunch guidance.
Why check the phenylalanine statement on zero-sugar cola?
Some variants use aspartame and carry a source-of-phenylalanine statement, including the named caffeine-free options described by Coca-Cola Great Britain and PepsiCo UK. If phenylalanine must be avoided, check the exact product label rather than relying on the general “diet cola” description.
