I know you're not SCD anymore, but I have a couple ideas from it that might help. People who can't handle cow products can often handle goat. Can you try goat cheese or goat yogurt? Same with eggs, people who can't handle chicken eggs can often handle duck or quail eggs. Also, it seems like carrots can be a bother to a lot of people, even though it's listed in the intro diet. If you don't want to completely eliminate it, maybe you could juice it instead?
Have you ever made a bone broth? It's supposed to have lots of nutrients in it, and be very gentle on the intestines.
What if it's the starches that bother you? You're eating a very high starch diet, which can be quite bothersome to some people.
Do you take any fish oil? The salmon you eat is a good anti-inflammatory food, but maybe you need more. Or you could eat a bunch more oily fish. Cook it with olive oil, and put a little garlic on it, both anti-inflammatory. There are also a lot of anti-inflammaory spices, like tumeric, oregano, and basil that you can cook with. Google anti-inflammatory foods and you'll come up with many more you can use.
Have you tried drinking green tea, mint tea, or ginger tea? All or supposed to be really good at soothing your insides. I drink a couple cups a day.
Since you can't do yogurt, do you take any probiotics? Maybe your gut ecology is messed up, and some acidophulus could help straighten things out.
And lastly, I've been reading a lot of good things about
the "green smoothie." Basically, you juice a bunch of stuff with a heavy focus on greens. I need to try making it myself. Google it for many recipes.
Oh, wait, I do have one more suggestion
. You said bananas bother you. Have you tried eating them when they're very ripe (lots of brown spots on the peel)? They're easier to digest when they're a little more soft.
