With speculation growing about Beyonce – is she pregnant or not? – fans spotted a possible hint on her Tumblr page: Her dinner menu in France included Salad Nicoise, a popular salad topped with tuna.

“I can’t do it anymore.”

That’s what oceanographer and former chief scientist at National Oceanic and Atmospheric Administration (NOAA) Sylvia Earle said this week when an ABC Nightline reporter asked her if she eats fish. The piece focused on her year stint at an underwater base called Aquarius, where she studied coral reefs in Key Largo. And although she grew up in a seafood-loving family and she herself has eaten “more than my share” now she says she “…can’t do it anymore” because she’s concerned about “all the pesticides and mercury floating out here.”

With 17 million followers on Twitter, Kim Kardashian has an enormous opportunity to improve lives simply by sharing accurate information with her fans.

The Doctors television show hopes to “supply viewers with critical information to make informed and intelligent health care decisions.”

But can the program, which is hosted by former Bachelor reality TV star Dr. Travis Stork and features three other telegenic professionals, really be considered a serious authority if it all too frequently promotes the latest diet trends, health fads and bogus medical claims?

Food reporter, Michele Henry, writes in today’s Toronto Star: “Choosing to put fish on your dinner plate might seem like a smart, healthy, even responsible choice. But surrounding these creatures is a roiling sea of controversy…”

No there’s not.

Sir Arthur Conan Doyle, author of the Sherlock Holmes series, must have been turning in his grave Thursday night when the latest episode of “Elementary” aired on CBS.

The character of “Watson,” played by Lucy Liu, remarks: “I was thinking sushi tonight.”

Mainstream researchers, doctors and dietitians agree that fringe eco-gurus who promote mercury in seafood scare-stories are more and more exposed by ground truth science these days. When the extensive scientific review that went into the USDA’s Dietary Guidelines concludes that “the benefits of consuming seafood far outweigh the risks, even for pregnant women” the debate is pretty much over.

It doesn’t surprise me anymore when people get information about seafood wrong and tuna in particular. But it does surprise me just how wrong they get it.

Let’s take for instance Andrew Freeman on TakePart, he’s an apparent expert on nutrition whose degree in history from UCLA and recent posts on prison overcrowding and a house in the UK made entirely of waste seem to back that credential up.

NBC has changed the headline--

Remember that time (read: this morning) when we put out a media alert warning reporters, producers and editors not to the  botch the headlines associated with any report on a new study in the Archives of Pediatrics & Adolescent Medicine that reviewed mercury’s potential effect on ADHD?
