Hi,
Yer book is closer to the mark.. That was googling & finding 27g sachets of Quaker?? The calorie count was close too! (Though I only take carbs into consideration.)
Lol, someone else will no doubt come along & tell me my math is out.. But that's OK. I don't do breakfast first thing, partly for the reason I'm more creative than "academic" in the mornings...
Hope this helps?!
