Very little is known about the relation between isoflavone intake and menopausal symptoms in Korean woman To find the effects and correlations between these factors, questionnaires(maternal factors, menopausal symptoms) anthropometric measurement, 24hr dietary recalls, and urinary isoflavones analysis were conducted in 100 postmenopausal women residing in the Kyunggi-do rural area. The average age hight and weight of the subject were 61.5 years, 153.6 cm and 56.2kg. The average age at menarche, menopause, and menstrual cycle were 16.7 years, 47.2 years, 29.8 years, respectively. Most of the postmenopausal women experienced mildly menopausal symptoms. The mean calorie, protein and calcium intake were 1417.6 kcal(74.7% of the Korean RDA) 53.2 g(88.6% of the Korean RDA) and 454.0mg(65.6% of the Korean RDA) respectively. The ration of energy from carbohydrate, protein, and fat was 68: 15: 17 The average isoflavone intake from soy foods was 27.27 mg. The major food source of the isoflavone were soybeans and soybean curd. The average urinary isoflavone excretion was 2. 78nmol/mg Cr and showed significant positive correlation with isoflavone intake. Isoflavone intake from soy foods had a negative correlation with the severity of menopausal symptoms. Therefore, soy foods which contain isoflavone may have a protective effect on menopausal symptoms of women in Korea.

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$\rightarrow$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 $\leq$ -1, n=23), and osteoporosis ( T-score $\leq$ -2.5, n=17). The mean age, height, weight and BMI were 62.37 yr, 154.36 cm, 55.28 kg and 23.18 $kg/m^2$ 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.

The effects of dietary fiber on lipoprotein metabolism and cholesterol levels in plasma and liver differ depending on the specific types of fiber, the species of laboratory animals tested and experimental periods. Some dietary fibers appear to be effective in the prevention and cure of atherosclerosis. Experiments reported to date seem to indicate wheat fiber-most popular testing material-has little effect on the plasma total cholesterol levels and the lipoprotein metabolism. Pectin and guar gum appear to be quite effective for the prevention of atherosclerosis. They affect cholesterol metabolism by increasing bile acid excretion, decreasing the levels of total cholesterol, LDL and VLDL and increasing HDL levels in plasma. In the obesrvation made in human and animals, oat bran and rolled oat have also been reported to have cholesterol lowering effect in serum. But, since the experiments in this field has been few, further studies are needed. The serum cholesterol lowering effect of dietary fiber seems to be due to the decrease in lipid digestibility and absorption, and the increase of fecal bile acid excretion. In addition, effects of alfalfa cellulose and lignin on lipid metabolism remains unclear, and further studies are required. In fact, it has been reported that, compared to the control diet group, vegetarians have low serum cholesterol levels and they rarely develop diseases of lipid metabolism and atherosclerosis. Therefore, daily intakes of sufficient dietary fiber are recommended in terms of nutrition.

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.

The purpose of this study was to investigate the nutritional status, and serum copper and zinc status according to the body mass index in 99 middle school female students residing in Kyunggi-do, Korea. Subjects were assigned to one of three groups such as underweight (BMI$lt;20, n=38), normal(20≤BMI$lt;25, N=36) and overweight(BMI≥25, N=25) groups. The nutritional status of subjects was evaluated based on anthropomenetric measurements, questionnaires, 24-hr dietary recalls and blood analysis. The results were as follows: 1. The mean age, weight, height and BMI were 13.93 years, 55.19 kg, 158.40 cm and 21.96 kg/m respectively. 2. The mean daily energy intake was 94.22% of RDA for Koreans. The ratio of energy coming from catbohydrate, fat and protein was 63: 24: 13. Underweight group showed significantly the lowest intakes of oils and fats among three groups (p$lt;0.05). 3. The mean daily intakes of Cu and Zn were 1.37 mg and 7.37 mg. 4. The most important dietary soures of Cu and Zn were cereals, and there were no significant differences of Cu and Zn intakes among the three groups. 5. The mean serum levels of Cu and Zn of subjects were 105.80 ug/dL and 99.15 ug/dL respectively. Underweight group showed the lowest serum Cu level (p$lt;0.001) but had highest serum Zn level (p$lt;0.001) among the three groups. To summarize the results, middle school female students did not show significantly different trend of nutrients intakes according to their BMIs. Also their Ca, Fe and Zn intakes were lower than RDA for Koreans. and especially underweight group showed the lowest serum Cu level but had highest serum Zn level among the three groups.

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.
