I also subscribe to the DNA theory. I get most of my information from
here and it's mostly reliable. My doctor claims that smoking is a negative factor in Crohns' and diet is a major player. I'll go with the diet, but I smoke and it doesn't seem to have affected me one way or the other. Other than the usual deleterious effects of course.
Mostly I watch what I eat (but sometimes I cheat
) and stay close to the bathroom. No surgeries yet, thank Bob.
