Dr. Oz — The Senate's Favorite Snake Oil Salesman

Mehmet Oz was a legitimate cardiac surgeon at Columbia before The Dr. Oz Show turned him into America's most trusted quack. A 2014 BMJ study found that only 33% of his on-air recommendations were supported by scientific evidence. He promoted green coffee bean extract (debunked), raspberry ketones (debunked), and garcinia cambogia (debunked) — each generating millions in supplement sales for companies he wasn't even affiliated with. He was hauled before Congress in 2014 and scolded for being "complicit in this scam." Then he ran for U.S. Senate. Lost. Returned to TV. The grift never stops.
