Our take

CleanPlate review

Zero sugar lemon-lime fizz with no lemon or lime

Paper Boat Zero Sugar Lemon Lime is a 600 ml sparkling drink made from carbonated water with two sweeteners (sucralose and erythritol), natural and nature-identical flavours, two acidity regulators, iodised salt and a preservative. The panel is printed per 100 ml, with a 200 ml serve, and the pack is marked veg.

CleanPlate scores it [L]EE1. The E for nutrition is low: almost no credited protein, fibre or micronutrients per 100 ml. The E for ingredients reflects mostly refined or industrial ingredients, with additives that cost points: sucralose, erythritol and flavouring. The [L] marks a hollow label promise: the lemon named on the pack is not in the ingredient list. The 1 for risk is low: sodium, free sugar and saturated fat are all modest (sodium 51 mg, free sugar 0 g, saturated fat 0 g per 100 ml).
