If you care about food at all, you don't want this. It spoils all the fun of eating. And frankly, though this bitter taste seems to be the only effect, whatever's causing it can't be totally benign. I don't know if it's my imagination, but I feel a wee bit woozy.

I understand that pine nuts sourced in Italy and North America don't have this effect. Of course, they're terribly expensive. I love 'em, but I can live with other nuts.
