I never had a glass of soda (called pop where I grew up) until I was 18 years old. With seven kids and a mechanics salary, Mom and Dad could not afford the pop luxury. I think it is too simplisitic to look for any one food related product as the cause of a disease. There are too many of us with CD with such varying backgrounds and dietary structures for me to ever think that one food item could be the cause.
I do know that carbonation is bad on my guts when I am in a flare.
Dx'd '90 (emergency rupture), symptoms ignored long before that, '03 fistulas and bad flagyl reactions, B12 weekly, Pentasa [until I surrender to the bigger meds]
I'm riding on the escalator of life....
