Shoppers cutting back on sugar
If you want fizzy drinks at home while reducing sugar, compare the sugars-per-100ml figure on each pack. The NHS suggests sugar-free, diet and no-added-sugar drinks as alternatives to sugary fizzy drinks.
Who is this choice for?
Cola drinkers avoiding caffeine
Choose the exact variant rather than relying on its zero-sugar name. Coca-Cola GB lists caffeine flavouring in Coca-Cola Zero Sugar, while Pepsi UK lists caffeine in Pepsi Max and separately identifies Pepsi Max No Caffeine.
Households topping up on cans
Check the can count and volume against what your household will use. Multipacks come in different sizes, so the format matters as well as the drink you choose.
What should you check?
Start with the nutrition panel, then check the exact variant’s ingredients and pack format before adding it to your top-up shop.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Read sugars per 100ml on the current pack, rather than relying on a brand family name. Coca-Cola GB and Pepsi UK each state 0g per 100ml for Coca-Cola Zero Sugar and Pepsi Max respectively. | I want a fizzy drink while cutting back on sugar. The NHS lists sugar-free, diet and no-added-sugar drinks as alternatives to sugary fizzy drinks. |
| Caffeine | Look for an explicit caffeine-free label on the exact variant. Coca-Cola Zero Sugar and standard Pepsi Max list caffeine; Pepsi UK separately identifies Pepsi Max No Caffeine. | If I am avoiding caffeine, a zero-sugar label alone does not answer my question. |
| Sweeteners | Read the ingredients and any phenylalanine statement. Coca-Cola Zero Sugar and Pepsi Max list aspartame and state that they contain a source of phenylalanine. | When buying for someone with PKU, I need to check the exact drink. The Food Standards Agency identifies aspartame as a possible risk for people with PKU. |
| Acidity | Do not treat a zero-sugar label as an indication that a drink is non-acidic. Wirral Community Health and Care NHS Foundation Trust notes that diet and sugar-free soft drinks can be very acidic and cause tooth wear. | For a routine between-meal drink, I do not want to assume fizzy drinks are interchangeable with water. |
| Pack size | Compare the number of cans and their volume, or the bottle volume. Check the exact label again if the retailer substitutes a different variant. | I want enough for a short household top-up without choosing a larger pack than I need. |
Common buying mistakes
-
Assuming zero sugar also means no caffeine
Coca-Cola GB lists caffeine flavouring in Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in standard Pepsi Max.
If caffeine avoidance matters, choose a variant explicitly labelled caffeine-free and check its current ingredients.
-
Overlooking the warning relevant to PKU
Coca-Cola Zero Sugar and Pepsi Max list aspartame and a source of phenylalanine. The Food Standards Agency identifies aspartame as a possible risk for people with PKU.
Check the ingredients and warning on the exact pack before buying for someone with PKU.
-
Treating sugar-free fizz like water
Wirral Community Health and Care NHS Foundation Trust warns that diet and sugar-free soft drinks can be very acidic and cause tooth wear.
Keep that distinction in mind when choosing a routine between-meal drink; its dental guidance also advises against brushing straight after a soft drink.
-
Choosing a pack by can count alone
Can counts do not show how much drink is in each can, and a large multipack may exceed a short top-up need.
Compare both the number of cans and their stated volume before choosing a format.

Pepsi
Pepsi Max and Pepsi Max No Caffeine address different caffeine needs.

Questions about diet fizzy drinks
Does zero sugar mean a fizzy drink is caffeine-free?
No. Coca-Cola GB lists caffeine flavouring in Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in standard Pepsi Max. If you are avoiding caffeine, choose an explicitly caffeine-free variant and check its current label.
How can I check the sugar in a zero-sugar drink?
Read the sugars-per-100ml figure on the exact pack. Coca-Cola GB and Pepsi UK state 0g sugars per 100ml for Coca-Cola Zero Sugar and Pepsi Max respectively; the name alone does not tell you about caffeine or sweeteners.
What should I check when buying for someone with PKU?
Check the exact ingredients and phenylalanine statement rather than relying on a zero-sugar label. Coca-Cola Zero Sugar and Pepsi Max list aspartame and a source of phenylalanine; the Food Standards Agency identifies aspartame as a possible risk for people with PKU.
Is zero-sugar fizz the same as water for teeth?
No. Wirral Community Health and Care NHS Foundation Trust warns that sugar-free, diet and fizzy soft drinks can be very acidic and cause tooth wear. Removing sugar does not remove that acidity consideration.
Which pack format suits a short top-up?
Compare the can count and volume with what your household expects to use. Check the exact drink and variant on the pack as well, especially if a substitution would change your sugar, caffeine or ingredient choice.
