Is Preventative Medicine Supported By Scientific Evidence?

I was trained very well at Harvard Medical School and Conventional Science. If I see ideas out there that are in conflict with what I know to be scientifically true, obviously they don't belong in medical teaching, but there certainly are things out there that are unaccounted for.

For example, the whole mind body field, it runs up against the paradigm of materialism that dominates medicine today. Materialism says that if you see a change in the physical system the cause has to be physical. When you talk about mind and body interaction, you talking about non physical causation of physicals events that doesn't compute in the current scientific models.

So in that sense, that is threatening to the prevailing scientific paradigm, but to me, it's very reasonable it conforms with my experience, and it has great ethicacy utility.
