Food rich in copper: Cooked Oyster Leafy greens (kale, spinach, etc) Mushrooms Seeds (flax, sesame, etc) Nuts (pistachio, cashew, walnuts, etc) Avocado Liver I'm sure there's more.

Cooked oysters but not raw ones? Does the cooking impart copper somehow?

  There could be bioavailablility issues with raw oysters. I have zero idea of whether or not that is true, but it's certainly possible. It could also just be a general policy to not endorse eating raw shellfish.

  Wild guess on my part, but I suppose it could be possible that cooking the oyster makes more of its copper available for absorption. No idea if that's true, just making up a theory to support the conclusion.

  Cooking foods actually decreases the bioavailability of a lot of minerals, copper included. Another reason oysters are great is because of their zinc content, which helps ensure your copper-zinc ratio is in balance and you don't overdo it on copper.

    I was aware of heat-sensitive vitamins/vitamers but not minerals, TIL!

    > Cooking foods actually decreases the bioavailability of a lot of minerals, copper included. Don't you mean "copper not included" if cooked oyster imparts more copper?

      I don't believe that cooking oysters imparts more copper.
      - Chris2048 10y ago
        Or the bio-availability of it. Since "raw oysters" is listed, but not cooked, it implies that the copper in oysters becomes non-bio-available as a result of cooking?

  I did know that oysters are high in zinc. Interesting that zinc and copper are antagonists. Another great reason to eat more!
