There's your problem........I hope that wasn't your only source on which you based your opinion. Also, be wary of industry-funded studies which support industry positions - ON ANYTHING. Look for INDEPENDANTLY funded studies. Also, be wary of studies which LOOK like they are "independantly funded". Sometimes you have to dig down deep enough to follow the money trail and see that studies are paid for and presented in order to support a certain cause.
