I am just starting my raw transition, and I"m finding conflicting information about using oils and eating avocados. In particular, this doctor says all oils are bad for us

Can anyone comment, it seems likes lots of raw foodists and vegans eat avocados,and I thought Dean Ornish in his heart health books says they are good, but now I"m confused.

Thanks,
