The purpose of this study was to assess the nutritional status of iron and magnesium and the effect of iron supplementation during 8 weeks(from 20 to 28 weeks of gestation) on serum iron and magnesium status of 31 pregnant women in Kyungin area. The age, weight, and height of the subjects before pregnancy were investigated by questionnaires. At 20 and 28 weeks of gestation, data for food and nutrient intake were obtained by questionnaires and serum sample was obtained. According to the frequency of iron supplementation, subjects were divided into two groups(4</wk, 5≥/wk). The mean iron supplementation of 5≥/wk group(63.9㎎/day) was significantly higher than 4</wk group(10.3㎎/day). The mean age of subjects was 30.1 years old. The weight of subjects was significantly increased at 28 weeks compared than those carried at 20 weeks of gestation(p<0.001). The energy and vitamin B2 intakes were much less than the Korean RDA. Especially, calcium, iron and magnesium intakes showed half the levels compared with Korean RDA. At 28 weeks of gestation the serum total protein (p<0.001) albumin(p<0.01) and globulin (p<0.001) were significantly decreased. Total iron binding capacity(TIBC) was significantly increased (p<0.001), but serum ferritin(p<0.01) and magnesium (p<0.01) concentrations were significantly decreased. However, even 28 weeks of gestation 5≥/wk group showed higher serum iron and ferritin concentration and lower TIBC than 4</wk group. Serum magnesium concentration was significantly decreased by progressing the pregnancy and was showed the decreasing trend at 5 ≥/wk group. Therefore, iron supplementation should be conducted with concerning the mineral balance like magnesium.

The etiology of cancer is directly related to the role of nutrition and diet, but this conclusion is inescapable, and it cannot be stated too strongly. In laboratory experiments, the incidence and growth of tumors is suppressed in animals on restricted by total calorie intake. The epidemiological evidence supporting total calorie intake as a risk factor for cancer is slight and indirect, much of it is based on significant direct association between overweight or obesity and cancer. Epidemiological studies and experiments in animals provide convincing evidence that increasing the intake of total fat increases the incidence of cancer in the breast, prostate and colon. Data from studies in animals suggest that polyunsaturated fats enhance tumorigenesis more effectively than saturated fats. The data on human research suggested a dependency on the amount of total intake of fat, and is not clear on the type of dietary fat. In laboratory experments carcinogenesis was suppressed by diets containing levels of protein at, or below the minimum required for optimum growth. Sulfur-containing amino acids, particularly cystine was able to increase incidence of tumors and methionine has been reported to be protective against tumors. Epidemiological studies have suggested possible associations between high level of dietary protein and increased risk of cancer at a number of different sites. The evidence concerning the route of carbohydrates in the development of cancer in humans and animals is extremely limited because of so few studies. In one epidemiological study, the intake of sugar was correlated with increased mortality from pancreatic cancer and incidence of breast cancer. The majority of experimental studies indicate that high fiber ingredients depress the tumorigenicity of certain chemical carcinogens because they are relatively insoluble and therefore poorly fermentable, such as cellulose and bran. Epidemiological studies have yielded results that dietary fiber Protect against colorectal cancer. Studies in animals indicate that vitamins A.C. and E are associated with a reduced risk of cancer, but the data does not permit a clear distincition. There have been numerous studies in laboratory animals to determine the relationship between minerals and the incidence of cancer. In contrast, there have been very few epidemiological studies. The epidemiological and laboratory studies suggest that selenium may offer some protection against the risk of cancer. Zinc deficiency in animals appears to ratard the growth of tumors, whereas it enhances the incidence of some chemically induced cancers. Epidemiological studies have suggested that higher levels of dietary zinc are associated 1with an increase in the incidence of cancer at the breast and stomach, and lower levels of zinc in the serum and tissue of patients with esophageal, bronchogenic compared to corresponding levels in controls. Epidemiological and laboratory studies suggest that iron and molybdenum deficiency have consistently increased the incidence of gastric and esophageal cancer. Experiments in animals have indicated that pharmacological doses of copper appear to protect against chemically induced tumors. Limited laboratory evidence suggests that iodine deficiency is associated with an increased risk of mammary and thyroid cancer, but in humans the evidence not conclusive. The result of few studies suggest that ingestion of cadmium, arsenic and lead are associated with an increased risk of cancer. The occurrence of cancer from animal experimentation appears to be affected by differing levels and kinds of nutrients. It is also dependent upon dose and type of administration of various carcinogens, and species and strain of animal. In human epidemiological studies, results and interpretation of differing nutrient in the body. Also, individual variation of subjects and subject groups, along with different methods of testing contribute to variable results. However, it is clear, nutrients can influence cancer, but father research is warranted, no definitive and meaningful results can be drawn for firm conclusions.

The purpose of this study was to investigate the blood lipid levels of insufficiently nourished elementary school students in Gyeonggi area. Subjects were assigned to deficiency or normal group according to the percent of energy RDA intake. Their nutritional status and serum lipid were evaluated based on questionnaire. anthrometric measurements. 24-hr dietary recalls and blood analysis. The mean age of total subjects was 10.8 years and the average height. weight and obesity index of deficiency and normal group was no significant different. At the result of comparison the Korean RDA with mean daily intakes. all nutrients intakes of normal group were approached the Korean RDA's 75 percentile. But vitamin A. vitamin B_(2). niacin. folate. calcium and zinc intakes of deficiency group were lower than the Korean RDA's 75 percentile. The average food intake of deficiency and normal group was no significantly different. Pulse intakes of deficiency group was significantly lower than that of the normal group(p<0.05). but the nuts and seeds intakes of deficiency group was significantly lower than that of the normal group(p<0.05). The HDL-cholesterol level of deficiency group was significantly lower than that of normal group(p<0.001) and atherogenic index(AI) was significantly higher than that of normal group(p<0.01). To summarize the result. vitamin A. vitamin B_(2). niacin. folate. calcium and zinc intakes of deficiency group were lower than the Korean RDA's 75 percentile. Pulse(p<0.05) and nuts and seeds(p<0.05) intakes were significant difference of deficiency and normal group. And deficiency group had lower HDL-cholesterol and higher atherogenic index than those of the normal group. Also it was suggested that the blood lipids might be related to the adequate nutrients intakes approached the Korean RDA's of elementary school students.

Postmenopausal women lose more bone mass than men as a result of estrogen deprivation. The resultant low bone mineral density (BMD) is a major risk factor in the development of osteoporosis. Calcium, phosphorus and magnesium are main components of bone. The purpose of this study is to investigate nutrient intake and serum osteocalcin, Ca, P and Mg and their correlation to bone mineral density in Korean postmenopausal women residing in rural areas. We conducted 24 hour dietary recalls, anthropometric measurements and blood analysis on 60 postmenopausal women. The BMD of the lumbar spine (L2 → L4) and the femoral neck were measured by dual energy X-ray absorptiometry (DEXA). Subjects were assigned to one of three groups: normal (T-score > -1, n = 20), osteopenia ( -2.5 > T-score ≤ -1, n = 23), and osteoporosis (T-score ≤ -2.5, n = 17). The mean age, height, weight and BMI were 62.37 yr, 154.36 cm, 55.28 kg and 23.18 kg/㎡ respectively. The mean daily energy and protein intakes were 76.35% and 87.41% of RDA for Koreans. The mean intakes of calcium, phosphorus, and magnesium were 463.62 mg (66.23% of RDA), 955.32 mg (136.47% of RDA), 345.87 mg respectively. The mean serum levels of calcium, phosphorus and magnesium were 8.76 mg/dl, 3.80 mg/dl, and 2.10 mg/dl, respectively, and there were no significant differences among the three groups. However, the BMD of the femoral neck showed a significantly negative correlation with serum magnesium (p < 0.05). To summarize the results, most nutrient intakes (especially calcium) in postmenopausal women did not reach the RDA values for Koreans. Also, increase of serum magnesium levels may be related to bone loss. (Korean J Community Nutrition 7(1): 111~120, 2002)
