It sure sounds like your husband is experiencing spasms in his colon this can cause the symptoms you described and it is a common IBS symptoms. Rice is unlikely to be the cause. It is a very easily digested food.
Since he has been on Heather's eating for IBS diet has the number of bowel movements increased or decreased?
What sort of protein is he eating? Only chicken, turkey, fish and seafood?
You might supplement Heather's diet with the information in the first two links in my signature. The articles in these links explain a clinically tested diet for functional bowel disorders like IBS. Clinical trials in the UK and Australia have shown a 70-80% improvement of symptoms. May of us on the board use this approach with Heather's diet with considerable success.
Ask lots of question. There are many knowledgeable individuals on the board.
