Cola drinkers cutting down on sugar
If you normally have cola with lunch, compare the sugar figure on the exact variant’s nutrition panel. Coca-Cola GB and Pepsi UK list zero-sugar colas, but their standard zero-sugar versions contain caffeine.
Who is choosing a lunch drink?
People avoiding caffeine at lunch
A zero-sugar label does not tell you whether a drink contains caffeine. Pepsi Max No Caffeine and Coca-Cola Zero Sugar Caffeine Free are distinct variants; check the full name and ingredients when choosing.
People who prefer fizz without cola flavour
Sprite Zero Sugar offers a lemon-and-lime option, while Tesco lists Fanta Zero Orange among its fizzy drinks. Check the nutrition and ingredients on the particular pack you plan to buy.
What should you check before choosing?
Start with the sugar figure, then check caffeine and ingredients; flavour and pack format can narrow the choice after those requirements are clear.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar | Read the sugars figure per 100ml on the exact variant. Check the nutrition panel rather than relying only on words such as “diet” or “zero”. | I want to replace a sugary fizzy drink at lunch. The NHS suggests sugar-free, diet or no-added-sugar drinks as alternatives when cutting down on sugar. |
| Caffeine | Look for caffeine in the ingredients or an explicit caffeine-free variant name. If pregnant, consider caffeine from the whole day: NHS guidance sets a limit of 200mg a day during pregnancy. | Cola flavour appeals to me, but I may not want caffeine with lunch. Pepsi UK and Coca-Cola GB distinguish their caffeinated zero-sugar colas from named caffeine-free versions. |
| Sweeteners | Check the exact pack for aspartame or E951 and a phenylalanine statement. The NHS says aspartame is unsuitable for people with phenylketonuria (PKU). | If I am buying for someone with PKU, “zero sugar” alone cannot establish whether the drink is suitable. |
| Acidity | Do not treat a zero-sugar label as an answer to every dental consideration. The NHS associates acidic carbonated drinks with dental erosion regardless of sugar or sweetener content. | I want to cut down on sugar, but I also need to consider how often I choose an acidic fizzy drink. |
| Flavour | Compare cola with lemon-and-lime or fruit-flavoured options, then check the chosen flavour’s own label. Ingredients can differ between variants. | For this lunch, I would rather have citrus or fruit flavour than cola. |
| Hydration | Decide whether you want a sweetened fizzy drink at all. The NHS identifies water as a hydration choice and suggests sparkling water if you prefer fizz. | Sometimes I just want a drink alongside lunch; plain water or sparkling water meets that need without choosing a sweetened soft drink. |
What is easy to overlook?
-
Assuming zero sugar means no caffeine
Pepsi UK lists caffeine in Pepsi Max, and Coca-Cola GB lists caffeine flavouring in Coca-Cola Zero Sugar. Both brands also identify separate caffeine-free variants.
If you need to avoid caffeine, read the full variant name and ingredient list rather than choosing by the zero-sugar wording alone.
-
Overlooking aspartame when buying for someone with PKU
The NHS says aspartame is unsuitable for people with phenylketonuria (PKU) because it contains phenylalanine. A diet or zero-sugar description does not settle that question.
Check the exact flavour and pack for aspartame or E951 and the phenylalanine statement.

Assuming no sugar means no dental consideration
The NHS associates acidic carbonated drinks with dental erosion, including drinks without sugar.
Consider how often you have fizzy drinks, and choose water or plain sparkling water when you simply want something to drink with lunch.
Which brands offer relevant options?
Brand names can point you towards a flavour or variant, but the exact product label determines its sugar, caffeine and ingredient details.
Coca-Cola
Coca-Cola Zero Sugar and Coca-Cola Zero Sugar Caffeine Free cover two different cola choices.
- Coca-Cola GB lists 0g sugars for both named variants.
- The standard Zero Sugar ingredient list includes caffeine flavouring; choose the separately named caffeine-free variant if avoiding caffeine.
Pepsi
Pepsi Max and Pepsi Max No Caffeine offer zero-sugar cola choices with different caffeine status.
- Pepsi UK lists 0g sugars for both named products and identifies the No Caffeine variant.
- Pepsi Max lists caffeine among its flavourings; check which variant is on the pack.
Sprite
Sprite Zero Sugar is a lemon-and-lime alternative to cola.
- Coca-Cola GB lists 0g sugars for Sprite Zero Sugar.

Dr Pepper
Dr Pepper Zero offers another zero-sugar flavour choice.

Tesco
Tesco lists own-brand diet and zero-sugar fizzy drinks, including cola and non-cola options.
- Tesco Groceries lists Tesco Caffeine Free Diet Cola and Tesco Diet Lemonade.

Common questions
Can a diet fizzy drink replace a sugary one at lunch?
Yes, if cutting down on sugar is your aim and the replacement’s nutrition panel meets that need. The NHS suggests sugar-free, diet or no-added-sugar drinks instead of sugary fizzy drinks; check the exact variant rather than relying on its brand name.
Which zero-sugar colas are caffeine-free?
Pepsi Max No Caffeine and Coca-Cola Zero Sugar Caffeine Free are explicitly named caffeine-free variants. Pepsi UK and Coca-Cola GB list caffeine in standard Pepsi Max and Coca-Cola Zero Sugar respectively, so check the complete product name when buying.
What caffeine check matters during pregnancy?
NHS guidance says not to have more than 200mg of caffeine a day during pregnancy. A caffeine-free cola avoids adding caffeine from that drink, but caffeine from tea, coffee and other foods and drinks still counts across the day.
Does zero sugar make a fizzy drink suitable for someone with PKU?
No: sugar content does not establish suitability for someone with phenylketonuria (PKU). The NHS says aspartame is unsuitable for people with PKU because it contains phenylalanine; check the exact pack for aspartame or E951 and a phenylalanine statement.
Does a zero-sugar fizzy drink avoid dental concerns?
No. The NHS associates acidic carbonated drinks with dental erosion regardless of whether they contain sugar or sweeteners. Choosing zero sugar addresses a different consideration from how often you drink something acidic.
