Starting some time after the hour and fifteen minutes in the interview, Dr Benjamin Bikman goes into the mechanics of why seed oils are so bad for us and specifically heart disease. Yes, the oils we have been told for a generation were heart healthy. Randomized controlled trials can not be done on such research because of the time line. Bikman goes into the mechanism and what animal trials are available. They are not human trials so the information he presents is not proof but a hypothesis. It is a pretty compelling argument.

Very long interview, but anything Bikman says (me being a diabetic) is of interest to me because of his specific area of research and study.
