The purpose of this study was to investigate the relationship and lipids in healthy adults on self-selected diets. These subjects consisted of 40 female college students residing in Chungnam. Anthropometric measure-ments, diet intake measurements, and blood collection were conducted. Serum concentrations of 5 microminerals(As, Cr, Mn, Se, Ni), lipids(triglyceride, total cholesterol, HDL-cholesterol), and glucose were measured by an ICP spectrometer and biochemical analyzer. The results were as follows. The mean age of the subjects was 22.34 years and the mean weight, height, and BMI were 52.89kg, 161.29cm and 20.34, respectively. The mean serum concentrations appeared to be 14.60ug/dl(As), 1.87ug/dl(Cr), 0.18ug/dl(Mn), 23.50ug/dl(Se), 0.21ug/dl(Ni), 60.73mg/dl(triglyceride), 138.49mg/dl(total cholesterol), 65.95mg/dl(HDL-cholesterol), 60.39mg/dl(LDL-cholesterol) and 88.82mg/dl(glucose). When analyzed by Pearson’s correlation coefficient, the serum concentration of Cr was negatively correlated with Ca and vitamin B12 intake(p〈0.05, p〈0.05) respectively, Mn was negatively correlated with Na intake(p〈0.05), Ni, however, was positively correlated with K intake(p〈0.05). The serum concentration of Se was positively correlated with LDL-cholesterol(p〈0.05), Ni, however, negatively correlated with total cholesterol, HDL-cholesterol, LDL-cholesterol, and glucose, respectively(p〈0.001, p〈0.01, p〈0.05). Further studies are needed to clarify the precise micromineral intakes, nutritional assessment of microminerals, and cause-effect relation of microminerals and serum lipids.

The purpose of this study was to investigate the intake of micromonerals which play an importment role in lipid metabolism and the realtionships of micromine-rals with serum lipids in college women living Choong-Nam area. The nutritional status of subjects was evaluated based on anthropometric mea-surements, 24-hr dietary recali(collected for microminerals intakes analyses), and blood analyses. The results were as follows: The mean age, height, weight, and BMI were 2Oyears, 158cm, 55kg and $22.42kg/m^2$, respectively.(omitted)mitted)

The purpose of this study was to examine the intake of Cr, Cu, and Zn, which play important roles in lipid metabolism, and the relationship of these microminerals with serum lipids of healthy college living in the Choongnam area. The nutritional status of the subjects(35 women) was evaluated based on anthropometric measurements, 24-hr dietary recall for 3 days. Three-day meals and fasting blood were collected to analyze Cr, Cu, and Zn. The mean age, height, weight and BMI were 20 years, 158 cm, 55kg and 22.42kg/$m^2$ respectively. The mean daily energy intake was 85.9% of RDA for Koreans. The ratio of energy from carbohydrate, protein and fat was 60 : 24 : 16. The mean daily intake of Cr, Cu, and Zn was 60.07 $\mu\textrm{g}$/day, 2.64 mg/day, and 11.35 mg/day, respectively. The mean serum levels of Cr, Cu, and Zn were 143$\mu$g/dl, 81.34$\mu$g/dl, adn 101.54$\mu$g/dl, respectively. The mean serum levels of total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol were 158.56mg/dl, 29.27 mg/dl, 56.00mg/dl, 6.12mg/dl, respectively. In conclusion, the subjects of the present study were healthy and consumed normal levls of dietary Cr, Cu and Zn, which play roles in lipid metabolism. Therefore, serum lipids of the subjects were all in the normal range. There was no significant correlation between dietary microminerals and serum lipids.

Research was conducted to determine the micromineral status of grazing cattle in three climatic regions of the province of South Sulawesi, Indonesia. Soil, forage, blood and liver samples were collected within the Western, Central and Eastern regions in February-March and August-September of 1987. Forages were deficient in copper, selenium and zinc. Serum copper was deficient in all regions but zinc was deficient more in the dry season. Liver copper was deficient in all regions and both seasons except in the central region in the rainy season. Based on the analyses, microminerals most likely deficient in both the rainy and dry seasons for each region were as follows: Western-copper, selenium and zinc; Central-manganese and copper; Eastern-selenium, copper and zinc. Some degree of molybdenum excess was found in the Eastern region.

The purpose of this study was to study the intake of heavy metals such af arsenic, lead and cobalt and the relationship of dietary heavy metals with serum iron, topper, and zinc, which play important roles in hematopoiesis, in healthy college women living in Choongnam Korea, where we have detected heavy metals (As, Pb, Co) in some marine products in previous studies. The nutritional status of the subjects (35 women) was evaluated by anthropometric measurements, 24-hr dietary recall for 3 days. And 3-day diets (by weighing method) and blood were collected to analyze As, Pb, Co, Fe, Cu, Zn, Hb, Hct, and MCHC. The mean age, height, weight, and BMI were 20 years, 158 cm, 55 kg and 22.42 kg/$m^2$, respectively. The mean daily energy intake was 85.85% of RDA for Koreans. The ratio of energy from carbohydrate, protein, and fat was 60 : 24 : 16. The mean daily intake of heavy metals (As, Pb, Co) was 1.77 mg/day, 75.21 $\mu$g/day and 21.12 $\mu$g/day. And the mean daily intake of iron, copper, and Zinc concentrations were 97, 68, and 92% of normal values. The mean serum heavy metals (As, Pb, Co) were 16.14 $\mu$g/dl, 4.32 $\mu\textrm{g}$/dl and 0.02 $\mu$g/dr, respectively Mean blood levels of Fe, Cu, Zn, Hb, Hct, and MCHC were at normal levels. Dietary heavy metals except Co were not significantly different from serum Fe, Cu, Zn and Hb, Hct, and MCHC. However, there was a tendency toward lower serum concentration of Fe, Hb, Hct, and MCHC in the subjects with higher heavy metals (As) intake. Among heavy metals, only dietary Co showed a significant negative correlation with Hb (p< 0.001) and Hct (p < 0.001).
