I love Thai food too. I've always found two things to be true: It makes more sense to honestly track your eating for an entire day or week to get a real understanding of whether you are eating cleanly. And, there are no bad foods, some are just "cleaner" than others.
That said, every dish is different and you'd have to know a lot more about how it is prepared to figure out how it fits into your overall eating plan. Our favorite Thai restaurant (in Salem, OR) specializes in steamed fish, chicken, and veggies. SHe also does terrific fresh spring rolls that DH loves. Here in Germany, everything is fried - noodles, rice, veggies. I'll still eat it, I'll just modify the rest of my diet.
Hope it helps, Katie
