I was diagnosed about 5 years ago so I've come a long way since then with what I can and can't tolerate and been on elimination diet after elimination diet but still find myself in denial about a lot of veggies. I just can't accept that such healthy foods can be bad for my system! Haha I mean they are just vegetables right? Although this is what I've found I DO tolerate:
Almost all greens - spinach, bok choy, rocket, lettuces, silver beet, chard - jury is still deciding on kale though
Small amounts of garlic
What I Do NOT
And then the iffy ones I play with all the time:
Cooking seems to help my digestion and not eating too many salads in a row.
Hope that helps.
