Well, IF you want World Peace, I'd definitely pick Hemp.
What I was trying to say (I'm not always very eloquent) is that each oil seems to react differently with each person. Some want for Omega's, some want the amazing skin benefits you seem to get with coconut.....
I'd say it's always going to be self experimentation. Enjoy the trip.
Lately I've gotten into Coconut. My teeth get really white with this oil, don't know why, not questioning it, just going with it.
