General guidelines

• Have your home tap water checked to be sure that it doesn’t have high levels of copper. If the pipes to your home are copper, be sure to run water through them before using the water for cooking or drinking. Copper can leach into the water as it sits in pipes.

• Don’t cook with copper-lined bowls, pots, pans, or cooking utensils.

• Read food labels. Note the copper content if it's available.

Making food choices

• Choose breads, rolls, cereals, and pastas made from refined flour, and white rice. Don't have wheat germ, bran cereals, or bran breads.

• Eat vegetables, but avoid vegetable juice cocktails, mushrooms, and potatoes with skin. Canned sweet potatoes are OK but not fresh sweet potatoes.

• Don't have beans, including peas, lentils, and lima, garbanzo, pinto, red, black, or soybeans.

• Don’t eat tofu.

• Don’t eat commercially dried fruit, fruit leathers, raisins, or prunes.

• Don't eat avocados.

• Limit mangos, papayas, pineapple, kiwi, and pears.

• Don't eat foods that contain chocolate or cocoa.

• Don't eat nuts, peanut butter, or other nut butters.

• Don't drink any soy or chocolate drinks, instant breakfast drinks, or meal replacement drinks or bars.

• You may drink milk and eat dairy products that don’t contain soy or chocolate. Choose milk, yogurt, cheese (including cream cheese and cottage cheese), custard, eggs, or coconut milk.

• Eat small portions of animal protein. Don't have pork, lamb, dark-meat turkey or chicken, or organ meats such as liver. Don't have shellfish.

• Don't drink alcohol. It can be harmful to your liver.

• Talk with your healthcare provider before taking a multivitamin. People who are or plan to become pregnant should talk with their healthcare provider before taking a prenatal vitamin, because they contain copper.
