lol, no I'm not a SW consultant... I just have access to the website so can check syn values easily, plus I've been a member for 5 years so if I don't know a bit about it by now, then I'm scuppered!
1 sachet of dried yeast is only 1 syn, or 50g of fresh yeast is 1.5 syns
As for tortilla wraps, they are approx the following:
White - approx 58g = 8.5 syns
Wholemeal - approx 64g = 8 syns each
So wholemeal are obviously better
but still high-ish in syns
