Karen,
Kudos to your GI doc!
The FODMAP diet is a step in the right direction, but I feel obligated to point out a few problems with it that should be avoided for anyone with MC:
Of the foods that are considered to be recommended, (low FODMAP foods), the following foods are usually contraindicated for someone with MC:
Citrus fruits, (because citric acid is a problem for many of us)
All artificial sweeteners, (not just those that end in 'ol)
All dairy products are a problem for most of us, (including butter, all cheese, all lactose-free ice cream, yogurt, etc.)
Lettuce is extremely irritating to the gut for almost all of us, until after our gut heals
Celery and Tomatoes are a problem for some of us
No one can digest whole corn, but most of us can eat products made from corn meal, or masa
Spelt is a member of the genus Triticum, so it definitely contains gluten, which is off limits for most people who have MC
Remember that the FODMAP diet was developed to treat IBS, not MC. With MC, it's safe for most of us to eat meats, potatoes, sweet potatoes, rice, etc. I don't know how those foods are regarded with the FODMAP diet, but they are generally safe for us to eat, except in a few cases with individuals who have many food-sensitivities.
Good luck with your treatment program, and please keep us informed on your progress.
