This purpose of this study was to analyzed zinc intakes and effect of Zn(30mg ZnSO4/day) supplementation on plasma zinc level, serum HDL-cholesterol and serum Alkaline Phosphatase (AP) activity of Korean adults. The men consumed 8.52(±2.08) mg
of
zinc,
an the women consumed 6.4(±2.62( mg of zinc. Although protein intakes of subject were enough, zinc intakes and plasma zinc level were lower than normal values. The first source of zinc was cereal and grain group, the second was meat, fish, egg
and
soybean group. Two food groups supplied about 80% of zinc.
After two weeks of zinc supplementation, the zinc concentration in plasma was significantly increased. the highest plasma zinc level was 78.80ug/dl(men), 76.04ug/dl(women) at 2 weeks after zinc supplementation (p<0.05). Serum HDL-cholesterol was
significantly decreased by zinc supplementation. The lowest serum HDL-cholesterol levels was 39.29mg/dl(men). 44.84mg/dl(women) at 4 weeks after zinc supplementation(p<0.01). Serum AP activity was significantly increased by zinc supplementation.
The
highest AT activity was 86.40 units/L(men), 67.93units/L(women)at 2 weeks after zinc supplementation(p<0.05). It seems that the supplementation of 30mg ZnSHO4/day can be beneficial for improving zinc nutriture. However it can be negative factor
on
coronary heart disease because serum HDL-cholesterol was significantly decreased(p<0.01).
