| Research Abstract |
To determine the daily intake of trace elements and magnesium for Japanese, dietary survey was carried out on various groups of Japanese and its intake were calculated from the foor tables presented in literatures. The average daily intake of nine elements in adult womem living in an agricultural area, Shiga Prefecture were estimated as follows: Ca: 563 mg P: 1102 mg, Fe: 10.6 mg, Na: 4595 mg, K: 3211 mg, Mg: 241 mg, Mn: 3.2 mg, Cu: 1.4 mg. The fact that a good correlation between certain mineral level in serum and their dietary intake were not always observed, but sometimes a good correlations were observed to intake of other minerals, suggests that, serum mineral levels are infulenced not only by intake of the same mineral but also by other mineral intake. Blood mineral levels of inhabitants in Thailand were lower than normal values of Japanese and so were insufficient. In animal experiments, it has been clarified that magnesium and calcium were decreased in blood and bone, and increased in soft tissues of rats fed low protein low energy diet. It has also been clarified that the effect of magnesium dificiency was remarkable for lactaging mother rats rather than their lactating infants. A clinical experiment suggests that zinc and copper dismetallosis is a possible pathological factor of hebephrenia.
