Marj, it's always best to learn from yourself rather than follow someone else's diet suggestions (even a doctor's) everyone is different and just because a food is tolerated by someone else didn't mean it will by you!
I notice you have had a pouch for over 20 years so presumably you have some idea which foods upset you and which don't. Do you have a specific concern that's leading you to want to restrict your diet
95% of digestion occurs in the part of the digestive tract that we still have, and outr nutritional requirements are still the same, so really you wouldn't restrict anything if possible. Avoiding fruit and veg doesn't sound sustainable in the long run.
The scd diet is useful for identifying problem foods, the plan is you only do it in the short term until you identify what's bothering you speciffically..
Your more likely to have health issues if you have a poor diet, so you should never exclude food (and especially not food groups) if there is anyway to avoid it
