Compared to cod, which minerals did perch show significantly higher concentration of in one study?
Answer
Calcium, Iron, Potassium, Zinc, Copper, and Manganese
While both ocean perch and cod are recognized as valuable protein sources, specific comparative analyses highlight mineral advantages for perch. In one instance examining nutrient density, ocean perch was found to contain significantly higher concentrations of several key minerals when juxtaposed with cod. These minerals include Calcium, which supports bone structure; Iron, vital for oxygen transport; Potassium, critical for fluid balance; as well as Zinc, Copper, and Manganese, all necessary for various enzymatic and immune functions. Although cod may lead in some nutrients like Selenium, perch demonstrated a broader superiority across this group of essential minerals.
