For children, the NHS recommends water and milk as everyday drinks. If you are choosing an occasional fizzy drink with an after-school snack, a diet or zero-sugar version addresses sugar content, but check the exact variant for caffeine; a sugar-free fizzy drink can still be acidic.
If a fizzy drink is part of an after-school snack, compare the exact product’s sugar and caffeine information rather than treating every diet-labelled drink alike. The NHS recommends water and milk as children’s everyday drinks.
Zero sugar does not mean caffeine-free: Pepsi UK lists caffeine in regular Pepsi MAX, while Pepsi MAX No Caffeine is a separate variant. Check the name and ingredients of the drink you intend to buy.
Drinks provided by state-funded schools in England fall under School Food Standards. The Department for Education’s guidance concerns school provision, not a parent’s drink purchase for a snack at home after school.
Start with whether the drink is for everyday use or an occasional fizzy choice. Then compare the exact variant and serving size, especially if avoiding caffeine matters.
| Priority | What to check | Your needs |
|---|---|---|
| Everyday drink | Decide whether a fizzy drink is wanted at all. The NHS recommends water and milk as children’s everyday drinks. | For a regular drink after school, I would choose water or milk; a fizzy drink would be an occasional choice. |
| Sugar | Read sugars per 100ml and per serving on the exact pack. For comparison, Pepsi UK lists 0g sugars per 330ml for Pepsi MAX No Caffeine; that figure applies to that variant. | If I am buying a fizzy treat, I want to check its stated sugar content rather than rely on the front-of-pack name. |
| Caffeine | Check the full variant name and ingredients. Pepsi UK lists caffeine in regular Pepsi MAX and identifies Pepsi MAX No Caffeine as a separate product. | For a child or a later-afternoon drink, I want a product explicitly identified as caffeine-free if avoiding caffeine is important. |
| Acidity and frequency | Do not use a zero-sugar label as a test of acidity. Oxford Health NHS Foundation Trust notes that fizzy drinks are among acidic drinks and advises reducing how often they are consumed. | Even without sugar, I would not treat repeated fizzy drinks as equivalent to water or milk. |
| Flavour and pack | Check the exact flavour, can or bottle size and number of servings before choosing a pack. Confirm product details on that pack rather than assuming variants share ingredients. | I want a flavour the household will use and a pack size that fits occasional drinks with snacks. |
Zero sugar describes sugar content, not whether a fizzy drink is the right routine choice for a child. The NHS recommends water and milk as children’s everyday drinks, and Oxford Health NHS Foundation Trust notes that fizzy drinks can be acidic.
Keep water or milk as the usual after-school drink, and consider a zero-sugar version when choosing an occasional fizzy drink.
Pepsi UK lists caffeine in regular Pepsi MAX even though it lists 0g sugars per 330ml. Pepsi MAX No Caffeine is a distinct variant.
If you need to avoid caffeine, look for an explicit caffeine-free name or statement on the exact product and check its ingredients.
The Department for Education’s September 2026 guidance describes requirements for food and drink provided in state-funded schools in England. Buying a drink for home after school is a different situation.
For school provision in England, check the current School Food Standards and the school or caterer’s approved drinks. Do not assume a retail diet fizzy drink qualifies because it has no sugar.
These examples show why the exact flavour and variant matter; a brand name alone does not establish sugar or caffeine content.
Tesco Groceries lists Coca-Cola Zero Sugar, Diet Coke and Diet Coke No Caffeine in its diet and sugar-free cola category.
Pepsi UK identifies both regular Pepsi MAX and Pepsi MAX No Caffeine.
Tesco Groceries lists Sprite Zero Sugar as a lemon-lime alternative to cola.

These are fizzy-drink packs to consider if you are choosing an occasional drink with an after-school snack. Compare each exact pack’s sugar and caffeine information with your needs; this selection does not change the NHS advice to offer children water or milk as everyday drinks.
