Here is a link to a fairly good description of the FODMAP diet. Here is an detailed article written by the Australian doctor who did the original research. It was written to inform GP and GI docs about the FODMAP diet so they could inform their patients. It is quite technical but you may find the check list in Table 1 and some of the other tables of interest.
Good luck
