The main product in question concerns tart cherries.
"There's a lot of exuberance about cherries. Maybe that exuberance spread into statements that should not have been made," said Jane DePriest, marketing director for the Cherry Marketing Institute, a trade group that represents cherry farmers and marketers. "But no one, including the Cherry Marketing Institute and the companies involved, intended to mislead people." [Washington Post, Oct 28 2005]
The claims ranged from 'preventing cancer' to 'knocking out gout and heart disease.' I can't blame these guys. It was an excellent market strategy while it lasted. If you visit the some of the concerned websites, some of them have already edited and modified their health claims. From direct cures, the tone is now more objective, like a line that says: "Studies continue to develop showing the many health benefits that daily consumption of fruits can provide."
Fruits and veggies are still food items. They are not medicines or drugs which should undergo strict tests by the FDA before they go out into the market. Sure, they may reduce the risk of cancer or heart disease. But there is no solid guarantee. It may work, or it may NOT work.
It is good to hope, but in cases like this, I think hoping should be done within the bounds of reason and reality.
