Just bananas? - Johnny from iPhone

Hmmm, not with bananas since I don't eat them. I do get that with other foods and I have no idea why. - Anika

In terms of just the food, the level of iron or other metallic substances can react with any fillings you have in your teeth, similar to why licking a battery tastes metallic. Similar to this, lots of fruits recieve a post harvest dip to ensure shelf life and colour. Lots of these formulations contain iron and potassium which could be having a similar effect. Other reasons could be the level of starch in the food. Starch can cause a metallic taste in some baking sodas depending on how the starch is processed. Given that bananas are high in starch, that could trigger it. - Johnny

In the case of bananas, they're picked green and then sprayed with ethylene when they reach their wholesale market point. Bananas are high in latex so some people have reactions to that. But metallic... The only time I've heard of metallic taste brought on by food (as opposed to what the food is canned in or cooked on) is as a reaction to eating too many pine nuts. http://www.npr.org/blogs... - Spidra Webster

So the bananas were organic. It was the banana ice cream that Just Katie (I think that's who posted it) posted about. I don't generally eat bananas much but because I don't like the texture, the taste is fine. So I liked the ice cream except for the after taste. Johnny, I only have 1 filling and it is ceramic and it is about the size of a pin, so it can't be that. When I put the banana slices in the freezer they were on a metal cookie sheet, do you think it could have picked up the taste from that and transfered it. Kevin did not taste it, only I did, and I have not had the metallic taste with any other food that I can currently remember. - Rachel Lea Fox
