Whenever you're wondering whether you can believe the medical advice you see on TV, just refer to these neat pie charts.
They're based on a study published in the British Medical Journal last December: researchers looked at the health claims mentioned in 40 randomly selected episodes of the two most popular internationally syndicated health talk shows, The Dr. Oz Show and The Doctors.
They identified 479 recommendations from The Dr. Oz Show and 445 recommendations from The Doctors, finding that on average, each episode contained about a dozen bits of health wisdom.
Researchers' conclusion: about half of the health recommendations either had no evidence behind them or actually contradicted what the best-available science tells us. That means about half of what these TV doctors say to their millions of satellite patients is woo, and potentially harmful and wasteful woo at that.
