What food source is richest in copper?

Shellfish are recognized as one of the richest food sources of copper. This essential trace mineral plays a critical role in various bodily functions, including the formation of hemoglobin, collagen production, and the maintenance of nerve cells. Copper is also involved in energy production and the function of the immune system.

Shellfish, particularly oysters, mussels, and shrimp, contain significantly higher concentrations of copper compared to other food sources. For instance, just a small serving of oysters can provide more than the daily recommended intake of copper. This richness in copper content makes shellfish an excellent dietary choice for individuals looking to enhance their intake of this important mineral.

On the other hand, while vegetables like onions contain some copper, they do not come close to the levels found in shellfish. Whole grains and olive oil are also not significant sources of copper. Whole grains provide various nutrients and are beneficial in many respects, but their copper content is relatively low compared to that of shellfish. Olive oil, primarily a source of healthy fats, lacks significant amounts of minerals like copper. Therefore, shellfish distinctly stand out as the premier source for this vital nutrient.
