I suppose really one should compare cooked oats with uncooked, as in not actually 'museli' which of course does come with 'other stuff'. I have a no-added sugar nutty museli, but it has raisins and dates as well as nuts.

It does seem divisive! I guess,as you say, we just have to experiement with ourselves and see whether its 'safe' or 'jam'!!
what I like most about it, I've had it for breakfast for years and years, is that museli fills me up very well - I just don't get hunger pangs at 11 am (Winnie the Pooh's dangerous 'time for a little something'!!)
