Arla Protein Greens Mango Kale & Lime

200g, £1.25, most supermarkets. Per 100g: calories, 70; saturated fat, 0.1g; protein, 10g; sugar, 6.6g VERDICT:

Consists of a type of dairy called quark (made by warming soured milk, then straining it), so is naturally higher in protein. This is a larger pot than most yoghurts, with 20g of protein — 40 per cent of our daily requirement, and it will certainly fill you up, says Priya Tew. Most of the sugar comes from the milk. ‘ But the kale is not enough to count as one of your five-a-day.’ TASTE TEST: Soft cheese texture. Nice lime zing.
