I definitelty think genetics contribute but.....since most everyone in US has so many diff ancestries mixed together in them, I don't think that it'll be possible to use this ancestry thing to help people. It just won't be clearcut enuf. But I think that it's certainly worthwhile for individuals to experiment with what works for them, using HVV's diet as a starting point and then testing diff "no-no foods' to see if they personally react to them. BIG problem with this approach is, who wants to risk having pain/C or D if they're doing well on HVV's diet????
