Although dietary intake of pregnant is supposed to have beneficial effects on development of infants, it may be harmful for fetal growth and development since specific food is a common source of toxicants including heavy metal. The purpose of this study was to investigate the association of maternal food intake and mid-pregnancy and their newborns blood lead levels. Pregnant women of 18-20 weeks of gestation were recruited from prenatal clinic in Seoul, Cheonan and Ulsan. In 422 pregnant women, dietary intake during pregnancy was assessed by a 24-hour recall method. Blood sample from pregnant (18-20 wks) and their cord blood at delivery were collected. Blood leas levels were analyzed by atomic-absorption spectrometry methods. Pregnant blood lead levels whose meat and meat products intake were in the highest quartile was significantly higher compared to the lowest quartile. Maternal meat and meat products intake was positively correlated maternal blood lead level (r=0.120, P=0.014). After adjusting for age, maternal blood lead level was positively correlated with their newborn blood lead level (r=0.303, P=0.030). As maternal food intake effects on blood lead levels of pregnant, careful regulation of food intake during pregnancy is perceives to be important in order to bring about desirable pregnancy outcomes.

To provide approprate nutrition informatios and guidelines for the healthy school lunch program(SLP) menus, the nutritional quality of the SLP and the nutrients that affect the food cost of SLP were evaluated after analysis of recipes and food price lists of 776 menus collected from 10 elementary SLP schools in Seoul and Kyunggi province in Korea in the year of 1995. Index of nutritional quality of SLP menus were good enough, showing over 1.0 in all nutrients except vitamin A(0.86) in kyunggi province. The percent of calories from carbohydrates, protein and fat was 52%, 16% and 32%, while the polyunsaturated fatty acid/monousaturate fatty acid/saturated fatty acid(P/M/S) ratio was 1.0/0.95/1.15. On the other hand, the nutrient-cost evaluation showed that the most expersive nutrient for the RDA(Recommended Dietary Allowance) standard of SLP was origined from the cost of energy and vitamin A. In Pertary correlation analyses, the cost of SLP meals was positively asociated with energy(r=0.244, p<0.001), protein(r=0.306, p<0.001) and carbohydrate(r=0.159, p<0.001) in diet, while the most important predictor of the cost of SLP meal provides sufficient nutrients with enough calories, but fat level is somewhat higher than the suggested value from Dietary Guidelines for Koreans. These data also suggest that meals which could offer enough vitamin A might be included in SLP menus and the cost of a SLP meal can be reduced when choosing the cheap protein source food.

This study compared the nutritional quality of Korean adults's consumption of lunch prepared at home, commercial places, and institutions. The one day food intake data collected via 24-hour recall in the 2001 National Health and Nutrition Survey were analyzed. Individuals with 19-64 years of age were selected (n = 5,756). Sampling weights in the Survey were used to generate nationally representative estimates. Lunch was categorized into three groups according to the place where the lunch was prepared. home, commercial places, and institutions such as schools and work places. Comparison among the three groups was made for 19-39 years old men (n = 1,387) and women (n =1,572) and 40-64 years old men (n = 1,364) and women (1,433), respectively. The lunch prepared away from home contained more calories. The lunch prepared commercially was higher in calories percentages from fat than that prepared either at home or at institutions. Across the age and gender groups, lunch prepared at home contribute a high level of sodium intake. Among individuals with 40-64 years of age, but not those with 19-39 years of age, lunch prepared commercially was as sodium dense as that prepared at home. Among individuals with 19-39 years of age, the sodium density of lunch prepared commercially was about the same as that prepared at institutional food service of which the menus were planned by dieticians. Such differences in nutritional quality among meals prepared at home, commercial places, and institutions should be considered and applied for the content development of nutrition education and policy.

The aim of this study was to investigate changes in 7 nutritional components (fatty acid, protein, fat, ash, total dietary fiber (TDF), $\gamma$-aminobutyric acid (GABA), and $\gamma$-oryzanol) of paddy rice (PR) and brown rice (BR) throughout the germination process, as measured at different shoot lengths (10 mm, 20 mm, and 30 mm). With the increase of shoot length, the nutritional components' concentrations increased, as compared to the concentrations measured before germination. Moreover, BR exhibited higher GABA, $\gamma$-oryzanol, and protein than PR. Among the components, TDF, GABA, and $\gamma$-oryzanol showed significant concentration differences throughout germination, while the others exhibited only slight variations. In particular, GABA and $\gamma$-oryzanol were predominantly increased in grains of 10 mm shoot length. These compounds might prove to be important factors from germinated rice. Additionally, the germinated cultivar 'Keunnun' might also prove to be a very important food source, owing to its high GABA and $\gamma$-oryzanol contents. These results suggest that variations in nutritional components related to the increase of shoot length may prove to be important when considering the beneficial aspects of rice on human health.

This study was performed to investigate the stress level, dietary attitudes and nutrient intakes of Food and Nutrition major female students at a university located in Changwon. A total of 122 female students taking the course 'Meal Management' during 2001-2004 participated in this study. The general characteristics, stress level and dietary attitudes of the subjects were surveyed using a self-administered questionnaire. The nutrient intake data collected from 3-day food-record method were analyzed by the Computer Aided Nutritional Analysis Program. The symptoms by stress showed that 'eye strain', 'physically exhausted or get tired' and 'pains on neck or shoulders' were high in 59.4-81.8%. The mean scores of stress in 2001-2004 were 8.5-12.0 out of 30 points and the subjects in 2002 and 2004 scored significantly higher on stress level than the subjects in 2001 did (p < 0.00. The mean scores of dietary attitudes were 58.7-66.6 out of 100 points, most of the subjects are belonged to the 'fair' group in terms of dietary habits level. The stress level had a negative correlation with dietary habits (p < 0.001). About 1/3 of the subjects, the intake of calcium, vitamin $B_2$, vitamin A and iron were less than 75% of Korean RDA, whereas more than half of the subject, protein, vitamin C and phosphorus intake were more than 125% of RDA, and intake ratio of Ca and P showed an unbalance of 1 : 2. The animal protein intake was higher than the plant protein, whereas the animal vitamin A and iron intake were lower than vegetable food source. In 2001-2004, the index of nutritional quality (INQ) of vitamin $B_2$ and niacin was 0.56-0.98, and in 2003, the INQs of vitamin $B_2$ was 0.56, and that of niacin was 0.67, which was extremely low when compared to that of the other nutrients. Therefore, nutritional education is necessary if female university students are to practice optimal nutrition, including well-balanced diets of high nutritional quality.

The objective of this study was to evaluate the nutritional content of bullfrog meat from different parts of the animal, including fore-chest, thigh and calf. Bullfrog meat was found to be a rich source of proteins, essential amino acids and minerals, but with a low fat content, compared with other aquatic meat products. There was no significant difference (p>0.05) between thigh and calf in mineral content (K, P, Na, Mg, Ca, Zn, Fe, Cu, and Mn), but the contents of K, P, and Mg were higher in thigh and calf than in the fore-chest (p<0.05). The salt-soluble, water-soluble and insoluble protein bands in sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) electrophoresis, from fore-chest, thigh and calf were similar, with the most abundant bands being 35 kDa (salt-soluble protein), 35-48 kDa (water-soluble protein) and 48 kDa (insoluble protein). The results showed that the insoluble protein content in the fore-chest meat was higher than that in the thigh meat and calf meat, but the salt-soluble protein fraction was the most abundant in thigh meat. These results showed that the nutrients in different parts of bullfrog meat were different.

The giant mealworm beetle, Zophobas atratus (Coleoptera: Tenebrionidae), is a tropical beetle. As this beetle can be used as an ingredient in animal feed, the effects of brewer's spent grain (BSG) on the development and nutritional value of Z. atratus were investigated. As results, there were no significant differences on the larval survival rate, body weight, and duration at different content of BSG, mixed with conventional feed, wheat bran (WB). Based on these results, BSG can be mixed with wheat bran as a Z. atratus food ingredient without any problems. The nutritional value was compared between 100% wheat bran control and 50% BSG experimental groups. The moisture, crude protein, carbohydrates, and amino acids were 1.1-1.4 times higher in the 50% BSG group. In the BSG group, the linoleic acid content was 1.6 times higher than that in the control group. In the wheat bran group, the oleic acid content was 38.4%, which was 1.3 times higher than that in the BSG group. As minerals, the control and BSG groups showed high potassium and phosphorus contents. In terms of hazardous materials, four heavy metals (lead, mercury, arsenic, and cadmium) and two microorganisms (Escherichia coli and Salmonella spp.) were not detected. There were no significant differences in developmental characteristics between the wheat bran and BSG mixed groups, and the nutritional values were better in the BSG mixed group. Therefore, BSG can be used as alternative food source for rearing Z. atratus.

Soybean [Glycine max (L.) Merr.] seed is an important dietary source of protein, oil, carbohydrate, isoflavone and other various nutrients for humans and animals. However, there are anti-nutritional factors in the raw mature soybeans. Kunitz trypsin inhibitor (KTI) protein and stachyose are the main anti-nutritional factors in soybean seed. The ${\alpha}^{\prime}$-subunit of ${\beta}$-conglycinin protein exhibit poor nutritional and food processing properties. The genetic removal of the KTI and ${\alpha}^{\prime}$-subunit proteins will improve the nutritional value of the soybean seed. The objective of this research was to develop a new soybean strain with KTI and ${\alpha}^{\prime}$-subunit protein free ($titicgy_1cgy_1$ genotype) and proper agronomic traits. A breeding population was developed from the cross of the Bl-1 and 15G1 parents. A total of 168 $F_2$ seeds from the cross of the BL-1 and 15G1 parents were obtained. The segregation ratios of 9: 3: 3: 1 ($104Ti\_Cgy_{1\_}:\;30Ti\_cgy_1cgy_1:\;21cgy_1cgy_1Ti\_:\;13titicgy_1cgy_1$) between the Ti and $Cgy_1$ genes in the $F_2$ seeds were observed (${\chi}^2=5.12$, P=0.5-0.10). Two $F_4$ plant strains with proper agronomical traits and $titicgy_1cgy_1$ genotype (free of both KTI and ${\alpha}^{\prime}$-subunit protein) were selected and harvested. 2 strains (S1 and S2) had yellow seed coats and hilum. The plant height of the S1 strain was 65 centimeters. The 100-seed weight was 29.2 g. The plant height of the S2 strain was 66 centimeters and 100-seed weight was 26.2 g. The two strains selected in this research will be used to improve the new cultivar that will be free of the KTI and ${\alpha}^{\prime}$-subunit proteins.

Objective: A study was conducted to determine the chemical composition of banana meal and rice bran from Australia or South-East Asia and test the hypothesis that there are no differences in rice bran produced in different countries, but there are differences between full-fat and defatted rice bran. Methods: Two sources of banana meal and 22 sources of rice bran (full-fat or defatted) from Australia or South-East Asia were used. All samples were analyzed for dry matter, gross energy, nitrogen, amino acids (AA), acid hydrolyzed ether extract (AEE), ash, minerals, total starch, insoluble dietary fiber, and soluble dietary fiber. Banana meal was also analyzed for sugars including glucose, fructose, maltose, sucrose, stachyose, and raffinose. Results: Chemical analysis demonstrated that banana meal from the Philippines is primarily composed of starch. Full-fat rice bran from Australia had greater (p<0.05) concentrations of AEE, lysine, and glycine than samples from the Philippines and Vietnam. Full-fat rice bran from Australia and Thailand had greater (p<0.05) concentrations of gross energy and most AA than rice bran from Vietnam. Full-fat rice bran from Australia had greater (p<0.05) concentrations of tryptophan and manganese than all other sources, but full-fat rice bran from the Philippines contained less (p<0.05) zinc than all other sources of rice bran. Gross energy, AEE, and copper were greater (p<0.05) in full-fat rice bran compared with defatted rice bran, but defatted rice bran contained more (p<0.05) crude protein, ash, insoluble dietary fiber, total dietary fiber, AA, and some minerals than full-fat rice bran. Conclusion: Banana meal is a high-energy source that can be used as an alternative ingredient in livestock diets. Full-fat rice bran from Australia and Thailand contained more concentrations of AEE and AA than samples from the Philippines or Vietnam. Full-fat rice bran had more gross energy and AEE than defatted rice bran, whereas defatted rice bran contained more crude protein, ash, and total dietary fiber.

To determine patterns of preference for and consumption of milk and milk products in Seoul city, a study was conducted of 724 girls and 587 boys ranging in age from elementary school to collage level, from July to August, 1974. Findings are summarized as follows: In general, milk and milk products were liked by both children and adults. A contrasting low tendency to purchase such products was due to socioeconomics, habitual, and educational factors, as well as a lack of adequate nutritional information, especially with regard to milk. Knowledge of the value of milk as a source of calcium was lacking, especially among boys. The majority of homemakers understood that milk was nutritious, but not specifically as the best source of calcium for their families. Milk, especially in beverage form, was commonly regarded as food for the infant and small child. Grandparents would not drink it. Such a beliefe is similar to that found in under-developed or developing nations. The need for nutrition education must be emphasized. Milk and milk products are expensive foods, particularly for the low income family; but even in higher income levels, consumption was limited. Milk was consumed mostly by the younger family members, less by the older. Among the children, preference, knowledge, and concern with the nutritional value of milk increased with age of subjects. It is presumed that awareness improved with increasing length of school education. Greater frequency of milk intolerance was found with decreasing age of respondents: about 10 percent had some form of milk intolerance. This percentage will be found to be much higher in villages where milk is less familiar. This study indicated that respondents liked ice cream best of all the milk products. For beverage, they preferred cider and cola in summer, coffee and milk in winter. Smaller families consumed more milk than larger families. Household consumption of condensed milk was very low, mostly as coffeemate. Among households interviewed, as many had regular as irregular delivery of dairy milk. Average consumption ranged 0.5 to 1.5 Hop. Engel indices of these families ranged 20 to 60. Use of milk at home was very simple. Not many methods of preparation were found. The milk was used mostly as beverage. In order to improve the nutritional level of Korean children and adults who especially need additional calcium, milk and milk products are recommended as the best source of calcium. Nutrition education of children and their parents should receive greater emphasis.
