I, too, have had this metallic taste, becoming quite pronounced about 4 months post-op. Some days are better than others and I find that acidic foods really accentuate the metallic taste. I look forward to tomatoes fresh from the garden every summer, but this year it was a real disappointment. I have to add sugar to cut that acid (and metallic taste) so that I can even finish a portion of spaghetti. I had enjoyed chocolate, especially dark chocolate, before surgery, but it doesn't taste all that good any more. Given that I have significant facial nerve damage, my jaw gets sore pretty quickly with eating, so that along with the taste distortions, it does help to keep portion sizes down and hopefully continue to lose some weight. I'm in the food business, so this is a real bummer. Fruit tastes the best to me and I'll have to try the zinc idea to see if that helps.
