I had the same thing happen about 10 years ago after buying a bag of pine nuts and eating them all in 3 hours. The strange metallic taste from everything had me worried until I read about it on the internet. It lasted about 3 days and went away. I still eat pine nuts in pesto and probably some other sauces but I never eat a lot by eating them directly from a bag.
