Half of Dr. Oz’s medical advice is baseless or wrong, study says - The Washington Post
After paging through the relevant medical research, they found evidence only supported 46 percent of his recommendations, contradicted 15 percent and wasn’t available for 39 percent. The researchers conceded it was difficult to parse what was said and what was implied.
I remember my GF talking about a paper that she made regarding this subject (health advice on television). Can ask her to provide me the abstract so that interested people can contact her personally.
EDIT: It seems she wants to post it to a journal herself, so cannot say too much about it. She did tell me that those channels are indeed emitting bullshit.
