I use a protein powder all made from plants called PlantFusion. It's nut, soy, gluten, lactose etc. free. One serving supplies 43% of daily protein needs. I eat a super smootie made with bananas, fruits and veggs plus unsweetened Almond Milk. I have several Greek yogurts a day too. The more things are smoothed out and liquefied the better for me to digest. I eat an English muffin with a bit of peanut butter too.
When I eat other things they are chicken, mashed potatoes, mac and cheese and pizza etc. I also read a tip on here several years ago written by an UPS driver who ate 3 or 4 rice krispie treats a day. He couldn't go just anywhere to the restroom and the marshmellows were good for that pus it is a cereal but they contain a lot of sugar. I eat salty things too like saltine crackers and potato chips
I have chronic pouchitis and cuffitis so my diet hasn't cured me. I just eat what looks good to me. Red meat especially doesn't look or taste good. I quit eating it a year before my surgeries. Alcohol doesn't even taste good to me anymore and that's a good thing because I'm still taking pain medication. I miss having a few drinks with others around as things are funnier to those that are drinking, lol. When I drink on occasion I try to get in as much hydration as I can so I don't get dehydrated. The best is a bloody mary and second best is vodka or gin with orange juice or tonic water.
I use to use 2 packets of VSK#3DS daily, mixed in with the yogurts and smoothies. Since my balloon dilation of my j-pouch in February I quit using it hoping the high powered antibiotics rotation would work. I'm on an expensive Xifan for 2 weeks to Augmenin for 2 then back to Xifan etc. I recently took a week off and used 2-4 packets daily. I felt like my body needed it as I might have had a yeast infection. Who knows? We have to do like you said, what feels best for us.
One of the docs on my surgical team told me to take a few bites of everything and see how I felt. She didn'/t want me slamming pasta etc.
