| calcium deficiency | A low blood calcium (hypocalcaemia) makes the nervous system highly irritable with tetany (spasms of the hands and feet, muscle cramps, abdominal cramps, overly active reflexes, etc.). Chronic calcium deficiency contributes to poor mineralization of bones, soft bones (osteomalacia) and osteoporosis; and, in children, rickets and impaired growth. Food sources of calcium include dairy foods, some leafy green vegetables such as broccoli and collards, canned salmon, clams, oysters, calcium-fortified foods, and tofu. According to the National Academy of Sciences, adequate intake of calcium is 1 gram daily for both men and women. The upper limit for calcium intake is 2.5 grams daily. (12 Dec 1998) |

| calcium excess | Overly high intake of calcium (hypercalcaemia) may cause muscle weakness and constipation, affect the conduction of electrical impulses in the heart (heart block) lead to calcium stones in the urinary tract, impair kidney function (through nephrocalcinosis), and interfere with the absorption of iron predisposing to iron deficiency. According to the National Academy of Sciences, adequate intake of calcium is 1 gram daily for both men and women. The upper limit for calcium intake is 2.5 grams daily. (12 Dec 1998) |
