I have to eat this diet for life as you probably do, but I work with seasonings for good flavors. I try to eat potato in some form every day - sweet or white. I have to eat a lot of butter and gravies as I have several organs compromised (including stomach and pancreas). Remember to drink lots of water -- I use weak tea and find the warm or hot tea very helpful. Soda and all carbonation is a disaster. Green beans, avocado, all meats, are all excellent.
I make sure I get a large glass of whole milk. For munchies -- cheese and crackers, cottage cheese, deviled eggs, popcorn that I make myself - no chemicals - lots of peanut butter.
I bake my own baked beans and freeze up small containers and have them with high-quality hotdogs. Lunches are often toasted cheese, ham, corned beef, etc. on white bread. I cannot manage the chemicals so I use a slow cooker and make up a lot at once and use the freezer.
There is a whole lot you can do with winter squash too -- I am now able to have some lettuce and I love tomatoes but have to use sugar for them to digest. Berries, bananas, hot chocolate -- eggs of all kinds - quiche are all good.
I did discover products using baking powder do not set well and I cannot handle pasta except in very tiny amounts. I love artichokes too - hard to get good ones here but on occasion I indulge.....lobster is fabulous as well as real scallops for digestion - also salmon fillets. I buy good quality and eat well knowing the nutrition is hard to get right. I eat smallish meals three times a day and have 3 good snacks to even things out as there is so little stomach left.
I am not supposed to eat yogurt, uncooked veggies, but I taste things and watch to see what works --- peas and corn are actually okay once you are well healed - I am 2 years post-surgery and just recently I started getting good results there. I do not eat any medium or high fiber food.
My nutritionist said once I was a year out and well into the healing to forget looking at food limits but try to look at food as a rainbow array and pick carefully the things you know taste good and are safe in your body - (everyone is different and with us it changes a lot so be prepared) -- then try new things and enjoy food so it does not become a burden -- I liked the concept and found I started to really get excited about food again. I cannot eat nuts and olives purely will not digest but some pickles do - cranberry sauce has turned out to be super and I keep trying combos --- I did end up in the hospital when hot peppers were cooked in a pork recipe at a restaurant -- and the reaction was serious -- I am very, very careful to ask questions now!
I have been forbidden all protein drinks but V8 is really good and sometimes I use it with stews etc.
Hope this helps -- I look forward to finding all types of helps on this site!
