Abstract: Objective To study the effects of daily mineral intake on bone mineral density(BMD)of old people and the measures to prevent and treat the osteoporosis.Methods The daily nutrition intake and health were investigated in 309 old people aged over 60 years,132 male aged 65.4±4.0years,177 female aged 66.7±5.8years.Results The bone mineral content(BMC)and BMD in female were lower than that in male.The daily intake of calcium,manganese,copper,selenium of health male was higher than that of health female.The daily intake of potassium,calcium,magnesium,zinc,calcium(milk)and selenium of osteoporosis case was lower than that of health people of the same sex.BMD correlation with the daily intake of potassium,calcium,magnesium,iron,manganese,zinc,copper,phospor,selenium,calcium(milk)and ratio of calcium and phosphorus assumed significant positive relation.Conclusion The was definite relation between the daily mineral intake and BMD.The lack of daily intake of potassium,calcium,zinc,tec may lead the lower of the BMD.
