Have You Experienced 'Pine Mouth?' Have you even heard of it? 'Pine Mouth' is a "vile, bitter-metallic taste in your mouth that you just can't shake after eating pine nuts." It doesn't actually make you sick, but it makes everything you eat or drink taste horrible...and can last anywhere from two days to two weeks. It rarely hits eaters-I eat pinenuts all the time & have yet to experience it myself-but over the past few months the FDA has been getting more & more complaints about it.
No one knows what causes 'Pinemouth' yet, but there are two strong theories. The first is that some packages are stored improperly & a rancid pinenut oil could possibly be causing the outbreak of 'Pinemouth.' The second theory points to imported pinenuts from China
. Researchers in Switzerland identified two species of pinenuts being grown in China that have not traditionally been part of our pinenut supply. There's no definitive data that these are the pinenuts causing the bad reactions, but the second theory is that one of these species of pinenut has worked its way into the national supply and is causing the recent flood of 'Pinemouth' reports.
