Low Copper Diet for Wilson’s Disease
Wilson’s disease, also called hepatolenticular degeneration, is a hereditary disorder that affects the body’s ability to regulate its copper absorption and storage. Instead of excreting excess copper into the intestines and eventually out of the body, Wilson’s disease causes the body to store it in your kidneys, liver, eyes and brain. Wilson’s disease is a treatable condition, but caution must be taken as too much copper in the liver can be life-threatening.
Copper is important for the development of health bones, collagen, nerves and melanin in the skin. Excess copper is usually excreted through bile, but for people with Wilson’s disease this mechanism does not function effectively.
For patients with Wilson’s disease, it is important to avoid copper-rich foods, like organ meats and shellfish. However, dietary restrictions are usually not enough to control Wilson’s disease on their own. Drinking alcohol should also be avoided as it can further harm the liver, which may already be damaged from cirrhosis as a result of excessive copper storage. If necessary, your physician can prescribe medicines to help the body excrete excess copper. Treatment may also be needed for any existing liver or central nervous system damage.
Dietary Copper Tips
The copper content in food can vary depending on a number of factors:
- The copper content and location of the soil in which the food was grown, or the method used to process the food.
- Drinking water may contain elevated levels of copper. The copper content of your water should not be more than 0.1 ppm. If you have copper plumbing, the copper content of your water can be reduced by running the water for awhile before using it.
- Always check supplement labels to see if they contain copper. Consult your pharmacist for help finding a multivitamin that does not contain copper. Most prenatal vitamins are high in copper and should be avoided. If you are pregnant or intend to become pregnant, please have you obstetrician consult with you hepatologist before prescribing your prenatal vitamin.
- Copper cooking utensils can leave trace amounts in food and shouldn’t be used when trying to decrease copper intake.
