Mehmet Cengiz Öz (Turkish: [mehˈmet dʒenˈɟiz øz]; born June 11, 1960), known professionally as Dr. Oz, is a Turkish American television personality, cardiothoracic surgeon, Columbia University professor, pseudoscience promoter, and author.\n', '

Oz came to general prominence with appearances on The Oprah Winfrey Show beginning in 2004, and later on Larry King Live and other TV programs. In 2009, The Dr. Oz Show, a daily television program focusing on medical issues and personal health, was launched by Winfrey\'s Harpo Productions and Sony Pictures.\n', '

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 giving non-scientific advice and promoting pseudoscience. In a Senate hearing on weight loss scams, Senator Claire McCaskill chided Oz, saying: "The scientific community is almost monolithic against you in terms of the efficacy of the three products you call miracles". In 2014 the British Medical Journal examined over 400 medical or health recommendations from 40 episodes of his program and found that only 46% of his claims were supported by reputable research, while 15% of his claims contradicted medical research and the remainder of Oz\'s advice were either vague banalities or unsupported by research.\n', '
