53. He invites activists with no credentials on and calls them "scientists" when they are not.

Profiling Oz in The New Yorker, Michael Specter noted instances of Oz inviting controversial guests onto his show. One example is Jeffrey M. Smith, an activist against genetically modified food. "Oz identified Smith as a scientist", Specter wrote, "but Smith has no experience in genetics or agriculture, and has no scientific degree from any institution." Specter also criticized Oz because he "seems to have moved more firmly into the realm of tenuous treatments for serious conditions." Oz replied that he sees himself as a mediator and wants to provide many differing points of view, even if they are looked down upon by the conventional medical community.[13]

Health claims made on the show have been criticized by the medical community as 54% of health recommendations were not supported by published studies. The Dr. Oz Show was also criticized in the same study for an overreliance on dietary suggestions and reluctance to provide evidence of its claims. The study warned that conflicts of interest were rarely addressed and that viewers should be skeptical of claims made on the show.[2] On 29 January 2015, Scott Gavura posted on the website sciencebasedmedicine.org an article clarifying the Federal Trade Commission's prosecution of Lindsey Duncan (who falsely claimed to be a "Doctor&quot and the company that he was affiliated with to promote and to sell green coffee-bean extract (GCBE) as a weight-loss supplement. The extent of the product's popularity was propelled by its repeated promotion on the Dr. Oz Show, for which none of the show's personnel did any research on Duncan, his conflict of interest or his financial interest in the business, before declaring him an "expert". This lack of research by staff has been an ongoing criticism of the show in numerous cases in which Dr. Oz has homed in on a product to sensationalise.
