Recently eating habits are characterized by over intake of energy and insufficiency of vitamins and minerals. To examine mineral nutritional status of adult men, 20 healthy volunteer men (average age: 42) were selected and their blood samples were collected. Hematological parameters in blood and biochemical parameters in plasma were monitored. Concentrations of calcium(Ca), phosphorus(P), potassium(K), sodium(Na), magnesium(Mg), sulfur(S), iron(Fe), copper(Cu) and strontium(Sr) in blood after wet digestion by nitric acid were measured by inductively coupled plasma-atomic emission spectrometry (ICP-AES: Perkin Elmer Co. Ltd). Blood mineral levels were as follows (average); Ca: 56.9μg/ml, P: 404.2μg/ml, K: 1.74 mg/ml, Na: 1.88 mg/ml, Mg: 37.1μg/ml, S: 1.52 mg/ml, Zn: 7.75μg/ml, Fe: 530.0μg/ml, Cu: 0.75μg/ml, Sr: 24.0 ng/ml. Mineral intake were as follows (average; mg/day); Na: 4967, K: 2944, Ca: 480, Mg: 342, P: 1275, Fe: 9.3, Zn: 10.4, Cu: 1.3, Mn: 3.9. Mineral sufficiency rates to the Recommend Dietary Allowance (RDA) for Japanese men were as follows (average: %/RDA); K: 147, Ca: 80, Mg: 108, P: 182, Fe: 93, Zn: 88, Cu: 73. There were suggested that sufficiency rates on Ca, Fe, Zn and Cu were low and P was high. These results were consistent with the National Nutrition Survey 2002 in Japan. P concentration in plasma was correlated with T-Cho and TG. Cu concentration in plasma was correlated TP and negatively correlated A/G.
