Mehmet Cengiz Öz, known professionally as Dr. Oz, is a Turkish-American[2][3] television personality, cardiothoracic surgeon, Columbia University professor,[4] pseudoscience promoter,[5] journalist, and author.[6]
He is a proponent of alternative medicine, and has been criticized by physicians, government officials, and publications, including Popular Science and The New Yorker, for endorsing unproven products and non-scientific advice. The British Medical Journal published a study that found more than half of the recommendations on medical talk series like The Dr. Oz Show had either no evidence or contradicted medical research.[9] Donald Trump's appointment of Oz to the Council on Sports, Fitness, and Nutrition was criticized as an example of choosing "pundits over experts".[10][11]
