INNOCENT BUBBLES LEMON & LIME

330ml, £1.45, most supermarkets. Per 100ml: Calories, 27; sugar, 5.4g.

Ingredients: Spring water, apple juice, grape juice, lemon juice, lime juice.

Verdict: The sugar tax doesn’t apply to this drink because it’s sweetened with real fruit juice. But a can still has 18g (four-and-a-half teaspoons) or 60 per cent of an adult’s daily free sugar limit. Once it’s absorbed, the body won’t differentiate between the sugar in this and the sugar in cola. However, the juice supplies one of your five-a-day, and the citrus fruits provide much of your daily vitamin C requirement, as well as some folate, which can help reduce fatigue. 5/10
