The wild caught oysters contain more fats and proteins, and fewer carbohydrates, making them more balanced. They also have more calcium, iron, and vitamin A. What can explain the increased amounts of copper and zinc? It seems to me that not all wild caught oysters will have greater quantities of these metals, and so the mineral profile would depend largely on where the oysters are caught. However, on average, wild caught will likely provide more minerals than farmed oysters.

Are all these extra minerals good for you? It depends on how much you eat. Indeed, it can be easy to consume too much iron, zinc, and copper when eating oysters often leading to diarrhea, or even blood nose. Thus, it is best to just eat no more than 3-4 wild caught oysters and enjoy all the vitamins and minerals for the calorie.
