Households swapping sugary cola
If cola is part of shared meals or the weekly shop, compare the sugars figure as well as the serving format. A large bottle and a can multipack meet different needs even when both are labelled zero sugar.
Who is this choice for?
Households looking for caffeine-free cola
A zero-sugar label does not establish caffeine content. Coca-Cola Great Britain and Pepsi UK list caffeine in their standard Coca-Cola Zero Sugar and Pepsi Max formulations; Pepsi UK separately labels Pepsi Max No Caffeine as caffeine-free.
Households checking sweeteners and acidity
For someone with PKU, the NHS says aspartame is unsuitable, making the exact ingredients and phenylalanine warning important. Families considering teeth should also distinguish a drink without sugars from one without acidity: the NHS associates carbonated drinks with dental erosion.
What should you check before buying?
Check the label requirements that affect the household first, then choose a pack that suits how the cola will be served.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read sugars per 100ml, not just the front-of-pack wording. Coca-Cola Great Britain and Pepsi UK list 0g per 100ml for Coca-Cola Zero Sugar and Pepsi Max; Tesco lists less than 0.1g per 100ml for its Diet Cola. | I’m replacing sugary cola, so I want to compare the actual sugars figures before choosing a family-size pack. |
| Caffeine | Look for an explicit caffeine-free label. Standard Coca-Cola Zero Sugar and Pepsi Max list caffeine; Pepsi UK labels Pepsi Max No Caffeine as containing no caffeine. | Someone in the household needs a caffeine-free option, and a zero-sugar claim alone does not answer that question. |
| Sweeteners | Check the ingredients on the exact pack. Coca-Cola Zero Sugar and the cited Pepsi Max products list aspartame and a phenylalanine warning; Tesco lists acesulfame K and sucralose for its Diet Cola. The NHS says aspartame is unsuitable for people with PKU. | If PKU affects our household, I need to rule out a product containing aspartame rather than assume every sugar-free cola uses the same sweeteners. |
| Pack format | Compare the total quantity and serving format: a 2-litre bottle can be poured for a shared meal, while a 24 × 330ml pack provides separate cans. Check how much space the chosen pack needs. | For meals together, a bottle may suit us; for separate occasions, I’d rather have individual cans. |
| Acidity | Do not use the sugars figure as a measure of acidity. The NHS says carbonated drinks are associated with dental erosion because of their acid content, including drinks without sugars. | I want to reduce sugar without assuming that sugar-free fizzy cola is neutral for teeth. |
Common buying mistakes
-
Assuming sugar-free means tooth-neutral
Removing sugars does not remove the acidity of a fizzy drink. The NHS associates carbonated drinks with dental erosion because of their acid content.
Consider the sugars figure and the drink’s acidity as separate questions when choosing cola for the household.
-
Taking zero sugar to mean caffeine-free
Coca-Cola Great Britain and Pepsi UK list caffeine in standard Coca-Cola Zero Sugar and Pepsi Max. Pepsi Max No Caffeine is a separate product.
When caffeine avoidance matters, look for an explicit caffeine-free label on the exact variant.
-
Choosing by brand instead of checking sweeteners
Sweetener blends differ between the cited products. The NHS says aspartame is unsuitable for people with PKU, and the cited Coca-Cola Zero Sugar and Pepsi Max labels carry phenylalanine warnings.
For a household member with PKU, check each pack for aspartame or E951 and its phenylalanine warning before buying.
Brand and own-label references
These product-line details help distinguish formulations; a brand name on its own does not establish a drink’s caffeine or sweetener content.
Coca-Cola
Coca-Cola Great Britain describes Coca-Cola Zero Sugar and Diet Coke as separate sugar-free drinks with different flavour blends. The company positions Zero Sugar as closer in taste to Coca-Cola Original Taste; that is its own description, not an independent taste comparison.
- Coca-Cola Great Britain lists 0g sugars per 100ml for Coca-Cola Zero Sugar.
- Its cited standard formulation lists caffeine flavouring and aspartame and carries a phenylalanine warning.
Pepsi
Pepsi UK distinguishes standard Pepsi Max from Pepsi Max No Caffeine, which it labels as containing no caffeine and no sugar.
- Pepsi UK lists 0g sugars for Pepsi Max and labels Pepsi Max No Caffeine as sugar-free.
- Both cited variants list aspartame and carry a phenylalanine warning; standard Pepsi Max also lists caffeine flavouring.
Tesco
Tesco describes its Diet Cola 2-litre bottle as a no-added-sugar drink with caffeine and sweeteners, providing a large-bottle own-label format for shared servings.
- Tesco lists less than 0.1g sugars per 100ml and names acesulfame K and sucralose as sweeteners for this product.
- The drink contains caffeine. Tesco advises checking the pack because recipes and product information can change.

This pack contains 18 individual cans rather than the 24 in the other can multipacks shown here.

Frequently asked questions
Does “no added sugar” mean a cola contains no sugars?
Not necessarily: read sugars per 100ml on the nutrition panel. Tesco lists less than 0.1g per 100ml for its no-added-sugar Diet Cola, while Coca-Cola Great Britain and Pepsi UK list 0g per 100ml for Coca-Cola Zero Sugar and Pepsi Max.
Is zero-sugar cola automatically caffeine-free?
No. Standard Coca-Cola Zero Sugar and Pepsi Max list caffeine flavouring. If caffeine avoidance matters, choose an explicitly caffeine-free variant, such as Pepsi Max No Caffeine, and check the exact pack.
What should someone with PKU check on a cola label?
Check for aspartame or E951 and a phenylalanine warning. The NHS says aspartame is unsuitable for people with PKU; the cited Coca-Cola Zero Sugar, Pepsi Max and Pepsi Max No Caffeine formulations contain aspartame.
Is sugar-free fizzy cola neutral for teeth?
No. The NHS says replacing sugars with approved sweeteners in a drink without sugars can help reduce sugar-related tooth-decay risk, but it also associates carbonated drinks with dental erosion because of their acid content.
Should a large household choose 2-litre bottles or cans?
Choose by serving pattern: a 2-litre bottle can be poured at a shared meal, while a can multipack provides separate portions for different occasions. Compare the number and size of containers, and check that the pack fits your available storage space.
