Am pre-surgery and very afraid of the changes I will experience in digestion. I would like to move towards a plant-based diet (a la Esselstyn), but I've heard that post-surgery, people don't tolerate whole grains well. Please share your digestive changes with me and inform me on what to expect - Please!

As I'm only six weeks out I haven't tried many grains. I was told to avoid things like pasta, rice, and untoasted bread. I've been able to eat a slice of toasted wheat bread but that's really the only thing I've attempted so far. My NUT warned me that rice maybe hard to digest so I'm waiting until I'm about eight weeks out to try it.
