Half of Dr. Oz's Advice Unproven or Wrong: Study

From the WebMD Archives

Dec. 19, 2014 -- More than half of Dr. Oz's recommendations are contradicted or not supported by medical research, a new study says.

Dr. Mehmet Oz is an extremely popular talk show host who dispenses health advice to millions of viewers, but he's been widely criticized for recommending unproven treatments.

For example, during an appearance before Congress in June, Sen. Claire McCaskill (D-Mo.) told Oz he gave people false hope and said his shows were a "recipe for disaster." And a study that Oz said showed the effectiveness of coffee bean weight-loss pills was retracted last month, the Washington Post reported.

"Recommendations made on medical talk shows often lack adequate information on specific benefits or the magnitude of the effects of these benefits," said the new study in the British Medical Journal.

The authors added that the "public should be skeptical about recommendations made on medical talk shows," the Post reported.
