Have you heard of Pine Mouth? I certainly hadn't until a friend mentioned that she had eaten some pine nuts and had a metallic/bitter taste in her mouth for days afterwards. Weeks later, a second friend mentioned the same thing.
So I did a little research...
Apparently, the initial concern was that pine nuts from China may be suspect. There was concern that the lack of a strong food safety track record may have been to blame for imported Chinese pine nuts' ability to cause an aftertaste in your mouth. But reports now continue that pine nuts from other parts of the world have caused the same reaction.
Has this ever happened to you?
I have successfully dodged the pine nut mouth epidemic, but I have to be honest with you, after reading about pine mouth and talking to my friends, I will think twice before eating pine nuts again.
