Low Copper Diet Diet For Wilson's Disease Purpose Wilson's disease is a hereditary disorder in which the body retains too much copper. Copper is a trace mineral in the body. This means it is essential for good health, but only a tiny amount is needed. When excess copper accumulates, it is stored in the eyes, brain, kidneys, and liver. Excess copper collecting in the liver causes cirrhosis of the liver, which is a serious, life-threatening condition. However, Wilson's disease is treatable. Copper is found in different amounts in a wide variety of foods. Therefore, dietary restriction alone is usually not enough to control Wilson's disease. Medicines such as Cuprime and Depen (generic name: D-penicillamine) and Syprine (generic name: trientine) are used to help excrete excess copper with the urine. Still, it is helpful to avoid copper-rich foods as much as possible. The dietary intake of copper should be less than 1.0 mg per day. Nutrition facts A low copper diet is generally adequate in all the nutrients necessary for good health. However, patients taking D-penicillamine may develop a deficiency of vitamin B-6 (pyridoxine), and the physician may prescribe a supplement of 25 mg daily. Special Considerations The copper content in a specific food can vary depending on a number of factors. The copper content and the location of the soil in which the food was grown, or the method used to process the food, for example, can affect how much copper is in the food when eaten. In general, the low copper diet is meant to restrict foods that are usually high in copper, especially organ meats, shellfish, dried beans, peas, whole wheat, and chocolate. Drinking water should be analyzed because it may contain too much copper. If the water contains more than 100 micrograms per liter, then bottled demineralized water should be used. This water should contain only 1 microgram of copper per liter. Demineralized water and distilled water are processed differently and may not contain the same amount of copper. Check with the physician or registered dietitian for more information. Avoid drinking alcohol. It can be harmful to the liver, and the liver may already be damaged from Wilson's disease. Read food labels; some prepared foods list the copper content. Always check the labels of vitamin/mineral supplements to see if they contain copper. For better control of copper intake, choose only average portions or serving sizes of foods. Examples of average portions are 3 to 4 oz of meat, fish, or poultry; 1/2 cup of vegetables; one slice of bread. Do not use copper cooking utensils. Patient's with Wilson's disease should have initial and periodic consultations with a registered dietitian to make sure copper in the diet is being adequately controlled.
