I'm not especially a Dr. Oz enthusiast but my wife (with Ph.D. in molecular biology) likes to follow him and then do some informal research about his subject matter. Her 25-word-or-less description is that Dr. Oz was a bit of a victim in that raspberry episode (which started a few years ago). Apparently he presented someone else's work, his own assessment splitting the edge between of amazement and disbelief. The perpetrators then used is picture and comment "wow" to sell their product, resulting in a lawsuit and other haggling. If he is guilty of anything it is in not vetting his subject matter carefully enough, but then he is running a TV show, not conducting medical research.
