Top Sources of Dietary Copper

Getting enough copper through your diet is generally easy for most people. Here's a breakdown of excellent food sources, categorized for easier understanding:

Organ Meats: The Copper Powerhouses

Organ meats consistently top the list when it comes to copper content. These nutrient-dense foods pack a significant punch:

Liver: Beef, chicken, and lamb livers are particularly high in copper. A 3-ounce serving of beef liver can provide a substantial portion of your daily recommended intake.
Kidney: Similar to liver, kidney offers a significant copper boost. Consider incorporating it into stews or other dishes.
Heart: While not as high as liver and kidney, heart still contributes a noteworthy amount of copper to your diet.

Shellfish: A Delicious and Nutritious Choice

Shellfish are another excellent source of copper, boasting both flavor and nutritional benefits:

Oysters: Renowned for their mineral content, oysters are exceptionally rich in copper. Just a few can significantly contribute to your daily needs.
Crab: Both blue crab and king crab are good sources of copper, offering a tasty way to increase your intake.
Lobster: Similar to crab, lobster provides a moderate amount of copper.

Other Notable Sources

While not as concentrated as the above, several other foods contribute to your overall copper intake:

Nuts and Seeds: Cashews, almonds, sesame seeds, and sunflower seeds all contain copper. They're also excellent sources of other essential nutrients.
Legumes: Lentils, chickpeas, and beans are good sources of plant-based copper and protein.
Mushrooms: Certain types of mushrooms, such as shiitake and oyster mushrooms, are relatively good sources of copper.
Dark Chocolate: A small amount of dark chocolate (70% cacao or higher) can contribute to your copper intake. Remember moderation is key due to the sugar and fat content.

Vegetables: A Supporting Role

Many vegetables contribute smaller amounts of copper. While they may not be the primary source, including a wide variety in your diet helps maintain overall nutrient balance.
