In my syns list it says that low fat and very low fat flavoured yoghurts have a syn value. Only natural yoghurt (low fat) is free. But it doesn't list brands specifically so I am unsure whether muller light is very low fat (0.5 syns per 100g) or low fat (1.5 syns per 100g). I love them and had one tonight thinking I was being all virtuous, only to realise they had so many syns! Also now finding that low calorie things like quavers have higher syn values than higher calorie stuff that is more filling. So I guess I now need to alter my ways!
