Can pine nuts cause bitter taste?

I have been eating pine nuts recently and for the past few days I have had a bitter taste in my mouth when ever I eat or drink anything. Someone here suggested it could be because of the pine nuts. I eat them quite often though, but I may have eaten more than usual. I have had this problem before some years ago, the taste lasted a few weeks then.

Can pine nuts cause bitter taste?
you might have a kind of allergic reaction
Reply:It is not an allergic reaction, it's a normal occurrence that happens 2-4 days after eating pine nuts. It can last for around 2-10 days. Report It

Reply:it depends...
Reply:Are you toasting them, first? For one, they would taste better. For another, all nuts are high in natural oils and you could have gotten a batch in which the oils have turned rancid. That would cause a nasty aftertaste. Keep them in the freezer between snacking to prevent that.
Reply:There is a lot of oil in pine nuts and this (taste) may linger in your mouth. I've really never eaten them like peanuts - 1. because they are costy and 2. because there are used to cook with.
