Copper is one of the trace minerals we need in our diet. It helps keep the body tissues healthy and is needed for proper use of iron in the body. Copper also is involved in antioxidant function. This trace mineral helps keep the immune system, nervous system, and heart healthy. What happens if we don't get enough copper? Copper deficiency is rare, but can occur in some conditions. Copper deficiency has been seen in pre-term infants who were fed milk formulas. Copper deficiency also can occur in people fed only through their veins for a long time (total parenteral nutrition). Copper deficiency caus es anemia, low white blood cell counts, and low bone density. Low intake during pregnancy may cause birth defects. High intake of iron or zinc can decrease copper absorption and cause a deficiency. It is best to get these minerals from foods we eat rather than supplements. How much copper do we need? The following table lists recommended daily intakes of copper. There is no difference in the amount needed by men and women, except when a woman is pregnant or breastfeeding. Life Stage Copper (mcg/day) Men, ages 19+ 900 Women, ages, 19+ 900 Pregnancy 1000 Bre astfeeding 1300 mcg = micrograms


Facts about Copper page 2 Reliable nutrition information may be found on the Internet at the following sites: http://solutionsforyourlife.ufl.edu http://www.nal.usda.gov/fnic http://www.nutrition.gov http://www.mayohealth.org How can we get enough copper? Shellfish and organ meats like liver are excellent sources of copper. Nuts and seeds, mushrooms, whole grain cereals, and legumes contain some copper. Here are some foods and the amount of copper they contain: Food Copper (mcg/serving) Beef Liver, cooked, 3 ounces 3830 Oysters, cooked, 3 ounces 640 Baked beans, vegetarian, canned, 1 cup 520 Sunflower seeds, oil roasted 1 ounce 510 Refried beans, canned, 1 cup 420 Mushrooms, cooked, cup 390 Peanuts, oil roasted, 1 ounce 360 Soy milk, 1 cup 350 Pecans, oil roasted, 1 ounce 340 Tofu, firm, cup 300 100% Bran Cereal, 1 ounce 270 Sweet potato, baked, medium 240 Casava, raw, 1 cup 210 Baked potato, 1 medium 200 Beef chuck roast, 3 ounces 140 Ground beef, broiled patty, 3 ounces 70 mcg = micrograms Breastfed infants get more copper than those fed formula. What about supplements? Most Americans get all the copper they need from the foods they eat. Supplements are not generally needed. Taking a multivitamin or mineral supplement with no more than the recommended daily intake is fine. How much is too much? Copper toxicity is ra re in healthy people. However, very high intakes over time can cause liver damage. Keep your total copper intake less than 10,000 mcg (10 mg) per day from food and supplements combined. Where can I get more information? The Family and Consumer Sciences (FCS) agent at your county Extension office may have more written information and nutrition classes for you to atte nd. Also, a registered dietitian (RD) can provide reliable information to you. June 2008
