A lot of things that may have been free, that aren't syn free now are due to the product changing.
I used to use a certain passatta with my meals, but all of a sudden my weight started to stand still and even increase. My consultant at the time went through everyhing I was eating, we couldn't work it out. However eventually we found out that it was the passatta, the makers changed the ingredients so It contained sugar in it. So whilst it may be unclear, it's usually because of that
