Choose cans when campers want separate portions to carry around the site; a 2L bottle makes more sense when a group will pour drinks together at its campsite base. Check the exact drink’s ingredients as well as its sugar content: the cited R. Whites Diet Lemonade and Sprite Zero Sugar cans contain aspartame, which the NHS says is unsuitable for people with phenylketonuria (PKU).
Who is this choice for?
Campers choosing zero-sugar drinks
If you want a fizzy lemon drink with sugar listed as 0g, compare the nutrition panel on the exact pack. Tesco’s R. Whites Diet Lemonade listing and ASDA’s Sprite Zero Sugar listing each state 0g sugars per 330ml can.
Groups sharing campsite food
A 2L bottle suits a group pouring drinks at its campsite base. Multipack cans give people separate portions to take with them instead of carrying an opened bottle.
Campers checking sweeteners
Anyone checking for aspartame, particularly because of PKU, needs to read the ingredients and phenylalanine warning on the exact pack. A zero-sugar name does not answer that question.
What should you check before packing?
Start with how the drinks will be served, then check the exact pack’s nutrition and ingredients before it goes into your camping supplies.
| Priority | What to check | Your needs |
| Pack format |
Compare 330ml cans with a 2L bottle. Decide whether drinks will be carried separately or poured at one campsite base. |
We’ll each take a drink with us, so separate cans are practical. If we’re serving everyone together, one large bottle may be easier to carry in. |
| Sugar and flavour |
Read sugars per can or per 100ml on the exact label. Check whether the drink is lemonade or a lemon-lime alternative. |
I want the sugar content stated clearly, but I also care whether the drink tastes of lemonade or lemon-lime. |
| Sweeteners |
Read the ingredient list and any phenylalanine warning. Tesco’s R. Whites Diet Lemonade cans and ASDA’s Sprite Zero Sugar cans list aspartame. |
If someone in our group has PKU, I need to check the exact pack rather than assume a zero-sugar drink is suitable. |
| Fizzy drinks |
Do not treat zero sugar as an answer to every consideration: the NHS associates carbonated drinks with dental erosion because of their acid content. |
I’m choosing a fizzy drink without sugar, while keeping its acidity in mind too. |
What is easy to overlook?
-
Assuming zero sugar means suitable for PKU
The cited R. Whites Diet Lemonade and Sprite Zero Sugar cans list aspartame. The NHS says aspartame is unsuitable for people with PKU, and UK government guidance identifies a source-of-phenylalanine warning for foods containing it.
Check the current pack’s ingredients and warning statement; the drink’s name alone is not enough.
-
Taking a shared bottle when everyone needs a drink to carry
A 2L bottle works differently from individually sealed 330ml cans when campers leave the campsite base.
Choose the format around where drinks will be served, rather than pack size alone.
-
Overlooking acidity in a zero-sugar fizzy drink
The NHS associates carbonated drinks with dental erosion due to their acid content, regardless of whether they contain sugar or sweeteners.
Do not treat a zero-sugar label as a statement about acidity.
-
Using an online listing instead of the pack label
The label on the drink you take camping is the one that applies to that pack.
Check its current nutrition, ingredients, warnings and best-before information when buying and before packing.

Frequently asked questions
Should I take cans or a 2L bottle to a festival campsite?
Take cans if campers want separate portions to carry; choose a 2L bottle when the group will pour drinks together at its campsite base. Tesco’s R. Whites Diet Lemonade listing says its pressurised 2L bottle should be opened slowly and handled with care.
Is diet or zero-sugar lemonade suitable for someone with PKU?
Not if the exact drink contains aspartame: the NHS says it is unsuitable for people with phenylketonuria (PKU). The cited R. Whites Diet Lemonade and Sprite Zero Sugar cans list aspartame, so check the ingredients and warning on every pack you consider.
What warning should I check for if a drink contains aspartame?
Look for a source-of-phenylalanine warning. UK government food-labelling guidance identifies the wording “Contains a source of phenylalanine” for aspartame; read it alongside the current ingredient list.
Does zero sugar remove the dental consideration of fizzy lemonade?
No. The NHS associates carbonated drinks with dental erosion because of their acid content, whether they contain sugar or sweeteners. A zero-sugar label describes sugar content, not acidity.
