To be totally honest you would be best steering clear of shop soup and if poss knocking up your own. Cheaper in the long run (not easier obviously), more nutritious and syn free!!
Shop soup is a minefield.
What PP means is that we wouldn't generally have food lists to pick and choose things like hex from because that does breach copyright. What you will find generally is answers to specific SYN enquiries so if you had a soup in mind and asked on here if was a Hex or if not what the syns were someone would come along and answer it but to list everything in that way would essentially remove the need to join slimming world at all. It's already fairly easy to work to the 1:20 rule. Think about weight watchers, can you, anywhere find a formula for working out pro points? There is a reason for that.
