I got a better idea. I hate the smell of tuna as well, go to costco and they sell kirkland chunk chicken 6 cans for $10. But each can is a good size and contains 65 grams of protein.
Hehe, I don't think it's actually metal, but that's the way tuna tastes to me. So tasteless it takes on the flavor of metal. Hard to describe it. Just bad.
Actually, I believe the solid white albacore canned tuna is the one with the highest mercury content. Regular chunk light tunna in water is supposed to be much better as far as mercury content is concerned.
