Isn't it hard to try new foods? As an IBS'er, I know so. Congratulations, Beth.
Sometimes, I notice, that after re-introducing a food or trying a new food or combination of foods it takes a few times until my body "knows" how to handle it. For example, if I haven't been eating any fruit for awhile and then have an all fruit smoothie, it will literally go thru me at hyper-speed. If I haven't had sushi in a few months and then eat it, I will react/respond. It took a few times of regularily eating carrots before I wouldn't see orange in my bm's, for example.
I know, it's not that cut and dry, not that plain and simple. It does take guts to test new foods/combo's, etc. Just know that it doesn't always work the first few times.
