Yeo Valley Natural Yoghurt

150g, 65p, most supermarkets. Per 100g: calories, 82; saturated fat, 2.9g; protein, 5.1g; sugar, 5.6g VERDICT:

‘This is brilliant as it has no added sugar ( the sugar is natural, from milk) or other ingredients,’ says dietitian Priya Tew. ‘The live bacteria (Bifidobacterium, L. Acidophilus and S. Thermophilus) are good for the gut. People may find it’s not sweet enough but adding fruit will help.’ TASTE TEST: Silky texture and pleasantly tangy.
