Copper deficiency

Copper deficiency

There are conflicting reports on the extent of deficiency in the U.S. One review indicates approximately 25% of adolescents, adults, and people over 65; do not meet the Recommended Dietary Allowance for copper.

A federal survey of food consumption determined that for women and men over the age of 19, average consumption from foods and beverages was 1.11 and 1.54 mg/day, respectively. Other conditions linked to copper deficiency include osteoporosis, osteoarthritis, rheumatoid arthritis, cardiovascular disease, colon cancer, and chronic conditions involving bone, connective tissue, heart and blood vessels, nervous system and immune system.

Copper deficiencies in these populations may result in anemia, bone abnormalities, impaired growth, weight gain, frequent infections (colds, flu, and pneumonia), poor motor coordination, and low energy.
