Wall Street Journal wonders if U.S. spied on Europe to learn about food label regulation

Regarding leaks to foreign news media with evidence that U.S. intelligence has been spying on its allies in Europe, the Wall Street Journalweighs in:

The real mystery (assuming the allegations are true) is what sort of intel did America's spies think they could glean from snooping on the European Union?

Could it have been the early word on the European Commission's directive this May (soon rescinded) mandating that olive oil be served only in nonrefillable bottles with tamper-proof caps and labels written in "clear and indelible lettering"? Or maybe it was the research notes of the three-year investigation leading to Brussels's 2011 decision to forbid bottled-water producers from claiming that water prevents dehydration—on the basis that the claim lacked scientific evidence?
