Families replacing sugary cola
If cola is an occasional addition to a holiday snack, a zero-sugar version addresses the sugar in that drink choice. Taste and caffeine still matter when choosing a variant.
Who is this choice for?
Households avoiding caffeine
Look beyond the words ‘diet’ and ‘zero sugar’. Diet Coke Caffeine Free and Pepsi MAX Caffeine Free are distinct options for shoppers who want a cola without caffeine.
People choosing drinks for younger children
Decide whether cola belongs in the snack shop at all. The NHS identifies water and milk as the best drinks for children; switching from sugary cola to zero-sugar cola does not make it the everyday drink choice.
What should you check?
Start with the drink’s role in the household, then check sugar, caffeine and ingredients before choosing a flavour.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Compare sugars per 100ml on the exact pack. The Coca-Cola and Pepsi zero-sugar varieties discussed here are specified as having 0g sugars per 100ml. | I want an occasional cola-style drink without the sugar in regular sugary cola. |
| Caffeine | Check for ‘Caffeine Free’ in the variant name and read its ingredients. Standard Coca-Cola Zero Sugar, Diet Coke and Pepsi MAX contain caffeine or caffeine-containing flavourings. | For this snack shop, avoiding caffeine matters as well as avoiding sugar. |
| Flavour | Coca-Cola describes Zero Sugar as closer to Coca-Cola Original Taste and Diet Coke as a different, lighter flavour. These are the brand’s descriptions, not a taste-test result. | Once sugar and caffeine are settled, I would choose the cola flavour the household prefers rather than assume diet and zero-sugar versions taste alike. |
| Ingredients | Read the sweetener ingredients and any ‘contains a source of phenylalanine’ statement on the exact variant. Check the pack when an individual has ingredient-specific dietary instructions. | Someone in the household needs the ingredient information checked before the drink is served. |
| Everyday drinks | Keep an occasional cola choice separate from routine drinks for children. The NHS identifies water and milk as the best drinks to give children. | I am buying for children and need a routine drink as well as deciding whether to include a cola treat. |
Common buying mistakes
-
Treating zero-sugar cola as an everyday child drink
A switch from sugary cola changes the sugar in that cola choice, but the NHS identifies water and milk as the best drinks for children.
Choose routine drinks separately, and decide whether an occasional cola belongs with the snacks.
-
Assuming ‘diet’ means caffeine-free
Standard Diet Coke, Coca-Cola Zero Sugar and Pepsi MAX contain caffeine or caffeine-containing flavourings.
If avoiding caffeine matters, choose a specifically named caffeine-free variant and check the pack’s ingredients.
-
Reading only the ‘no sugar’ message
The zero-sugar products discussed here contain sweeteners and carry a statement that they contain a source of phenylalanine.
Read the label on the exact variant, particularly if someone has ingredient-specific dietary instructions.
-
Applying school-food rules to snacks bought for home
The Department for Education describes England’s school-food standards as applying to food and drink provided to pupils on school premises. Buying snacks for home during the holidays is a different setting.
If the drinks are instead being provided at a school, check the rules for that setting rather than using a home-shopping decision as the basis.

Questions about diet cola
Should zero-sugar cola be a child’s main drink during the holidays?
No. The NHS identifies water and milk as the best drinks for children. Zero-sugar cola changes the sugar in a cola choice, but it does not replace those everyday drinks.
How do Coca-Cola Zero Sugar and Diet Coke differ?
Coca-Cola describes both as sugar-free, but says Zero Sugar is intended to taste closer to Coca-Cola Original Taste and Diet Coke has a different, lighter flavour. Choose by taste preference after checking the exact variant’s caffeine and ingredients.
Does ‘diet’ or ‘zero sugar’ mean caffeine-free?
No. Standard Coca-Cola Zero Sugar, Diet Coke and Pepsi MAX contain caffeine or caffeine-containing flavourings. If avoiding caffeine matters, look for a specifically named variant such as Diet Coke Caffeine Free or Pepsi MAX Caffeine Free and check its pack.
What should I read on a zero-sugar cola label?
Check sugars per 100ml, caffeine in the ingredients, sweeteners and any statement that the drink contains a source of phenylalanine. Read the exact variant’s label, particularly if someone has ingredient-specific dietary instructions.
Do school-food rules govern cola bought for holiday snacks at home?
No: buying snacks for home is different from providing drinks to pupils at school. The Department for Education says England’s school-food standards apply to food and drink provided to pupils on school premises; check the applicable rules if you are buying for that setting.
