Question: What should I avoid eating if I have Wilson disease?
Answer: When you start treatment for Wilson disease, your doctor may recommend avoiding foods that are high in copper, such as

chocolate
liver
mushrooms
nuts
shellfish

After treatments have lowered your copper levels and you begin maintenance treatment, talk with your doctor about whether you can safely eat moderate amounts of these foods.

If your tap water comes from a well or runs through copper pipes, have the copper levels in your water checked. Water sitting in copper pipes may pick up copper. Run the water to flush the pipes before you drink the water or use it for cooking. You may need to use a water filter to remove copper from your tap water.

For safety reasons, talk with your doctor before using dietary supplements, such as vitamins, or any complementary or alternative medicines or medical practices. Some dietary supplements may contain copper.
