Come over to the Crohn's forum! There are three of us doing the fodmaps diet there.
You're best ignoring most of the websites. Fodmaps is an evolving diet (in that it is still being researched by the experts, and changed in accordance with the results gained), and a lot of information on the internet is either outdated or just plain inaccurate to start with. Your best sources areShepherdworks
, the practice of the dietitian who actually developed the diet, and
Monash University, in Melbourne, Australia (just Google "Monash fodmaps" to get lots of results.
Hope this is helpful, and do pop over to Crohn's if you want to chat with some other fodmappers.
