There's a new message today for teens and their parents regarding what they imbibe: Just say no to energy drinks, and yes to sports drinks only when necessary after intense workouts. Given that most children and adolescents don't work out intensely, "most kids shouldn't drink either of them, ever," concludes Jennifer LaRue Huget in the Washington Post's "The Checkup" blog.

A new report from the international ocean advocacy group Oceana claims that seafood fraud is rampant, not only undermining legal fishermen but also "consumer-driven efforts to do the right thing and ask for species that are responsibly managed," as Susan Carpenter reports in the Los Angeles Times' Greenspace blog.

The Wall Street Journal tells us that the upcoming release of Microsoft's Mango OS for mobile devices announced yesterday "dials up the phone wars." The long-anticipated upgrade, which some reports speculated might be delayed until next year, will be available to existing users for free in the fall. It focuses on improving the communications and Internet experience and Microsoft hopes it will encourage developers to release more applications.

E-commerce Times' headline almost says it best: "Nook Lust Drives Liberty Media to Court Barnes & Noble." The tabloid copy editor in us, however, wants to rewrite that to "Liberty Looks for a Little Nookie."

The Wall Street Journal 's David Kesmodel writes that R.J. Reynolds is "seizing on new antismoking laws in New York City" while the Winston-Salem Journal's Richard Craver says the hometown tobacco company is merely "attempting to make lemonade" out of the ban on smoking in the city's parks, beaches, boardwalks, and pedestrian plazas that was signed into law in February and takes effect today.

For a while this week, a decidedly unbusinesslike story sat at the top of WSJ.com's "Most Emailed Links." The headline reads, "The Diet That Shook Up Tennis? Starch Madness: Novak Djokovic's Domination of the Sport Has Coincided With His Gluten-Free Turn."

Why would Hershey CEO David J.

Plus, his daughter's going to college In California, and Del Monte is based in San Francisco.

The headline in the tabloid Boston Herald reads: "Doctors cook up way to give McDonald's Ronald the boot." What they've really doing, however, is ratcheting up the pressure, as the lede admits. There's little indication that the fast food giant's mascot -- or accompanying charitable works -- are going anywhere soon despite the fact that more than 200 physicians in the Boston area have signed a letter to McDonald's CEO James Skinner "asking him to halt its marketing to kids," Thomas Grillo reports.
