the bitter taste mystery

For the last few days Jacob and I have been suffering from this weird bitter taste in our mouths - could not identify what was happening, read about rattlesnake bites, but that seems highly unlikely:) It seemed a bit better today but after eating, it happened everytime. Then look what Jacob found out....and yes we had pine nuts for dinner on Thursday or Friday night!!!! Crazy.

Risks of eating pine nuts
The eating of pine nuts can cause serious taste disturbances, developing 1-3 days after consumption and lasting for days or weeks. A bitter, metallic taste is described. In general, a minority of pine nuts on the market present this problem. Though very unpleasant, there doesn't seem to be a real health concern.
This phenomenon was first described in a scientific paper in 2001.[6] Since the article, experiences of the phenomenon have been reported by hundreds of people worldwide (US, Canada, South Africa, Finland, Iceland, Germany, and many more).[7] [8]
The pine nuts involved typically contain triglycerides formed by 16-18° unsaturated fatty acids. No contamination with pesticide residues or heavy metals was found.
Some of the pine nuts involved were imported from China. However, in many countries packaged pine nuts are not required to state the country of origin or the species, and thus it is impossible to conclusively link the effect to a particular species or source country.
