Copper might not be the first nutrient that comes to mind, but it’s vital for maintaining a healthy body. It supports energy production, boosts immunity, aids iron absorption, and ensures your skin and hair remain vibrant. While copper deficiency is uncommon, ensuring your diet includes copper-rich foods helps keep your metabolism and immune system functioning optimally. Let’s explore the top 15 copper-rich foods you can easily add to your diet.
Why Copper is Essential for Your Health
Copper is crucial for several bodily functions:
