After reading your other post in another thread, it looks like you are speaking of a Candida albicans overgrowth. In this case you really shouldn’t be eating any foods that could possibly feed the Candida. It may be that the writer is doing just this with his list, meaning that he’s looking at some foods which feed yeast, which would make perfect sense, except the list is rather short if this is the case. You would be better served by looking at a list of foods that are safe to eat rather one that contains all the foods you shouldn’t eat.
But to answer your questions, all fruit, as well as jams and jellies would contain fructose which would feed the yeast. As far as bacon is concerned, it’s usually cured by using brown sugar and/or molasses. In addition, bacon is normally aged, and any food that is aged can contain mold.
