Health Advice of the Stars You Really Shouldn’t Take

4. Jenny McCarthy

Former Playboy model turned TV personality Jenny McCarthy became the poster girl for autism when her son was diagnosed with the disorder. In specific, she was an outspoken advocate against vaccinations as she thought they were an autism trigger. The 1998 study she based her thoughts on was found to be fraudulent, and many other large-scale studies have shown there is no definitive link. She preached beliefs that were based on anecdotal information and helped fuel the anti-vax movement. She also claims that chelation therapy cured her son of autism, something that is not supported by medical consensus, leaving some people to question her son’s diagnosis in the first place. We applaud Jenny’s maternal desire to try everything she can to help her son, but she sold a lot of books and dispensed a lot of advice that was of questionable credibility.
