What is a low copper diet?

Some search terms matched

A low copper diet focuses on cutting back foods naturally high in copper—like nuts, seeds, chocolate, avocados, and shellfish—because too much copper can build up in the body when certain genes prevent proper regulation. For people with fibromyalgia, migraines, or chronic inflammation, reducing copper intake while supporting balance with nutrients like zinc, boron, molybdenum, and glutathione can make a dramatic difference in symptoms and overall health.
