@pleonasm - That's why I think it's great that scientists are isolating isoflavonoids and other substances like this, so that we can just, one day, take a pill in the morning that will do all the disease fighting for us.
I believe people should eat in moderation and that they should have a range of foods. I don't think there's a magic bullet, particularly since everyone is so different. But, I do think that we should try to do as much as we can to extend our lives. Why not? Who doesn't want to live forever?
