150g, 45p. Per 100g: calories, 95; saturated fat, 1.2g; protein, 4.6g; sugar, 13.8g VERDICT:

‘This is a classic example of how a yoghurt you’d think is healthier isn’t necessarily so, as it contains a massive amount of added sugar — three-and-a-half teaspoons, around half your daily limit,’ says Priya Tew. ‘Apart from calcium, I am not sure what the benefits of this are — there are no added probiotics, either.’ TASTE TEST: Thin texture and very sweet.
