Is Oprah Bad For You?

Earlier this week, the Dish pointed to Newsweek's battle against the daytime TV demigod. Here's the money quote:

[T]the truth is, some of what Oprah promotes isn't good, and a lot of the advice her guests dispense on the show is just bad....Some of the many experts who cross her stage offer interesting and useful information (props to you, Dr. Oz). Others gush nonsense. Oprah, who holds up her guests as prophets, can't seem to tell the difference.

Dr. John Grohol wonders if Oprah will respond:

A very interesting controversy. It would be even more interesting to see Oprah address this controversy directly on a future show, inviting the Newsweek authors and some of the science bloggers on to discuss how this sort of media promotion can ultimately be a great disservice to her loyal viewers.
