Whether they do or they don't, there are definitely SW consultants out there who have been instructed that certain items are being treated this way and are relaying this information to their group members, and because it is coming from them, the people we trust to deliver the plan accurately to us, we will always see questions about these sorts of thing.
However, the best advice is where possible, cook these things yourself, because you have control over what goes into the raw materials, and if that isn't possible, check the syn values but bear in mind that with anything that you don't have control over the cooking of, there may be hidden syns because when someone else is in charge of preparing it, they won't have the same consideration for the amounts of oil etc used as you do.
