This study was conducted to identify dietary factors that may affect the occurrence of gastric cancer in Koreans. Preoperative daily nutrition intake and diet quality of patients diagnosed with gastric cancer were evaluated. Collected data were comparatively analyzed by gender. The results were then used to prepare basic materials to aid in the creation of a desirable postoperative nutrition management program. The subjects of this study were 812 patients (562 men and 250 women) who were diagnosed with gastric cancer and admitted for surgery at Soonchunhyang University Hospital between January 2003 and December 2010. Nutrition intake and diet quality were evaluated by the 24-hr recall method, the nutrient adequacy ratio, mean adequacy ratio (MAR), nutrient density (ND), index of nutritional quality (INQ), dietary variety score (DVS), and dietary diversity score (DDS). The rate of skipping meals and eating fast, alcohol consumption, and smoking were significantly higher in males than those in females. The levels of energy, protein, fat, carbohydrate, phosphorous, sodium, potassium, vitamin $B_1$, vitamin $B_2$, niacin, and cholesterol consumption were significantly higher in males than those in females. Intake of fiber, zinc, vitamin A, retinol, carotene, folic acid were significantly higher in females than those in males. MAR in males was significantly higher (0.83) than that in females (0.79). INQ values were higher in females for zinc, vitamin A, vitamin $B_2$, vitamin $B_6$, and folic acid than those in males. The average DVS was 17.63 for females and 13.19 for males. The average DDS was 3.68 and the male's average score was 3.44, whereas the female's average score was 3.92. In conclusion, males had more dietary habit problems and poor nutritional balance than those of females. Our findings suggest that proper nutritional management and adequate dietary education for the primary prevention of gastric cancer should be emphasized in men.

The purpose of the study was to examine the changes of food and nutrient intakes of college students between 1999 and 2009. Dietary survey of 169 college students was conducted by a 24-hour recall method for three days in 2009. Food and nutrient intakes in 2009 were compared with the data from 106 students collected by the same methods in 1999. The intakes of cereals & grain products and vegetables in 2009 were lower than those of 1999, but the intakes of meats, eggs, milk & milk products, and manufactured food were higher. The intake of rice per person decreased greatly from 452.2 g in 1999 to 351.4 g in 2009 in males, and from 306.9 g to 237.2 g in females. While the intakes of protein, fat, thiamin, niacin, vitamin $B_6$, phosphorus, potassium, zinc, and cholesterol were significantly higher, the intakes of dietary fiber were significantly lower in 2009 compared to 1999 both in males and females. The nutrients consumed less than the Recommended Intakes were vitamin A, riboflavin, vitamin C, and calcium in males and additionally folate, iron, and zinc in females in both 1999 and 2009. The ratio of carbohydrate, protein and fat as energy was 61 : 15 : 24 and 60 : 14 : 26 in 1999, and 54 : 16 : 30 and 56 : 15 : 29 in 2009 in males and females respectively, showing that carbohydrate intake decreased and fat intake increased greatly. Our data suggest that nutrition education is necessary for college students to help them consume more vegetables and fruits and less fat and cholesterol.

The purpose of this study was to examine the correlation between nutrient intakes and bone mineral density in female university students. A total 27 female university students were measured the anthropometric characteristics, dietary intake and the bone mineral density of carpus using DEXA. The average age, height, weight, % body fat, WHR, and BMI of the subjects were 22.7 years, 161.5 cm, 57.0 kg, 29.9%, 0.8, 21.8 kg/$m^2$, respectively. Bone mineral density of ultradis and distal carpus as T-value were -1.5 and -0.4, respectively. The daily energy intake of the subjects was 1589.0kcal. And the intakes of energy, calcium, iron, zinc, vitamin $B_2$, and folic acid did not meet the Korean RDAs. The daily total food intake of the subjects was 1011.0g and food intake from cereals and vegetables was high. The major food groups of mineral intake were vegetables/cereals/milks/fishes for calcium, cereals/meat/vegetables/fishes for phosphorus, cereals/vegetables/meats for iron, seasonings/vegetables/cereals for sodium, vegetables/cereals/seasonings for potassium, and cereals/meats for zinc. The body weight and body mass index were significantly positive correlated to the bone mineral density of average carpus, respectively. The intakes of animal calcium and vitamin $B_2$ were significantly negative correlated to the bone mineral density of average carpus, respectively. In conclusion, bone mineral density in carpus and nutrient intakes of some female university students were low. Therefore, health management and the study on relation between bone mineral density in various site and long-term intakes of nutrients in many subjects are required.

The purpose of this study was to determine the effects of nutrient intake, screen time (television viewing and computer and/or video games) and physical activity on obesity in preschool children. Recruitment began in January 2008 by distributing letters to mothers who had children aged 6 years enrolled in daycare. Dietary intakes were obtained from the children's mothers, using the 24-hour recall method. The average height and weight of the children were 114.2 cm and 20.3 kg, respectively. Mean age, body weight, height and Kaup index were not significantly different between groups consisting of boys or girls. Assessment by the Kaup index showed that 14.0% of children were underweight, 69.0% were normal weight, 13.0% were overweight, and 4% were obese. The daily intakes of calcium, potassium, fiber, and folic acid in the group of boys were 77.7%, 58.5%, 80.4% and 88.9% respectively. as compared with the DRIs. The daily intakes of calcium, potassium, fiber, and folic acid in the group of girls were 77.7%, 58.5%, 80.4% and 88.9%, respectively. as compared with the DRIs. Intakes of protein, phosphorus, iron, zinc, vitamin A, thiamin, riboflavin, niacin, vitamin C, and vitamin E were higher than the DRIs. There were no difference among 3 groups (underweight, normal, overweight) in energy or nutrient intake. Preschool children with screen time (TV viewing and computer and/or video games use time) of >2 hours per day had significantly higher Kaup index values, and intakes of energy, carbohydrate, folic acid and zinc. In conclusion, preschool children with reported screen time (TV viewing and computer and/or video games use time) of >2 hours per day were fatter. Therefore, we need further investigate the relation between diet and screen time in preschool children to improve future nutrition education programs. Further studies are required to explore the effects of food intake and screen time (TV viewing and computer and/or video games use time) over a longer period of time.

임신과 수유 기간 동안 alcohol의 섭취가 어미와 새끼 쥐의 간내 copper 유용에 미치는 영향을 연구하기 위하여 cthanol(0 혹은 30%의 Kcal)과 copper(0.75 혹은 3.75mg/l 식이) 함량에 차이를 둔 식이조성으로 alcohol과 copper의 상호작용을 규명하는 factorial experiment를 수행하였다. 어미 쥐의 열량 섭취와 체중은 식이들에 의해 영향을 받지 않았다. 식이내 copper양이 적을 경우 alcohal을 섭취하지 않은 실험군과 비교하여 alcohol을 섭취한 실험군인 어미 쥐의 간 copper농도가 더욱 감소됨으로써 alcohol과 copper의 상호작용을 보여주었다. 새끼 쥐에게서는 식이내 copper 수준에 관계 없이 어미쥐의 alchol 섭취가 간의 총coppernein의 copper 농도에 반영되었다. Metallothionein의 zinc 함량은 metallothionetin의 copper함량과 반비례적인 관계로 보여주었다. 이상의 결과로 임신과 수유기 동안 식이내 copper함량이 적을 경우 alchol 섭취는 어미와 새끼 모두에게 copper 결핍을 초래할 수 있다는 것을 시사해준다.

To investigate the effects of dietary phytate reduction and zinc supplementation on biochemical iron parameters in elderly Korean women consuming inadequate iron, fifteen healthy women aged 64-75 years were recruited for a feeding study. A high-phytate diet (27.8 phytate:zinc molar ratio) was provided for 9 days, followed by a nine-day low-phytate diet(12.3) and a subsequent 28-day period of unregulated meals with zinc supplementation (22 mg/d as zinc gluconate). Serum iron increased significantly with the low-phytate diet (130.4 $\mu g$/L) but returned to the level observed during the high-phytate diet (113.0 $\mu g$ /L) period when subjects were taking zinc supplements (105.8 $\mu g$ /L). However, serum ferritin in the subjects decreased significantly with the low-phytate diet (73.8 $\mu g$ /L) as well as with zinc supplementation (57.2 $\mu g$ /L), compared to levels following consumption of the high-phytate diet (89.6 $\mu g$ /L). Transferrin receptor and transferrin saturation were unchanged with the treatments. In summary, zinc supplementation might result in deteriorated iron status in elderly Korean women who consume inadequate iron, while there was no significant effect from reducing dietary phytate.

This study was performed to compare the dietary intake and food sources of zinc (Zn), using a database of Zn composition developed in this study, between elementary schoolchildren in a remote rural area (RA, n=58, $9.9{\pm}1.7\;yrs$) and those in an urban area (UA, n=60, $9.4{\pm}1.8\;yrs$) in Chungnam province in Korea. A dietary survey for three days by food record method was performed. All kinds of foods (n=273) consumed by subjects were collected by aliquot sampling method, and the Zn content of these foods were analyzed by wet technique. The results showed that the daily mean intakes of energy, calcium, iron, and vitamin C from diet in the RA were in the range of 49-88% of the Korean DRI (KDRI), while those in the UA were similar to or greater than the KDRI, except for calcium and iron. The daily mean intake of Zn from the RA diet was $7.0{\pm}0.5\;mg/d$ ($114.1{\pm}8.4%$ of the KDRI), and $16.0{\pm}1.0\;mg/d$ ($258.3{\pm}16.3%$ of the KDRI) in that of the UA (p<0.001). The percentage of dietary intake of Zn less than 2/3 of the KDRI was 19.0% in the RA, in comparison to 1.7% in the UA. Those in the RA consumed Zn from plant foods more often than did those in the UA (p<0.001). Beef rib stew was the food source with highest Zn amount for the total subjects, followed by beef rib meat, roasted; and beef soup w/seasoned red pepper sauce. These results showed that some children in the RA had poor Zn nutrition based upon low intakes and poor food sources of Zn, while overall, children in the UA had good Zn nutrition. Therefore, those in RAs should have their Zn nutrition improved through government policy and nutrition education.

Purpose: This study was conducted to identify the association of dietary intake levels with ante-natal depression among pregnant women. Methods: Secondary data analysis was done using Can Pro software (version 3.0) to evaluate the diet intake levels with 24 hour recall diary method with 130 pregnant women visiting a general hospital. Statistical analysis included descriptive statistics, t-test, Mann-Whitney U test and adjusted logistic regression using the SPSS/WIN program. Results: Whole dietary intake levels of pregnant women were insufficient according to Recommended Nutrient Intake (RI) with the except of phosphorus intake. There were significant differences in RI by gestation period and high risk pregnancies. Non-depressed women showed more intake in niacin (z=1.33, p=.018) and zinc (t=3.99, p=.048) than depressed women did. Niacin was a significant determinant of ante-natal depression (Exp (B)=5.88, p=.47, 95% CI [1.02~23.83]). Conclusion: Dietary intake assessment would be necessary during pregnancies for the screening of ante-natal depression. For ante-natal depression care, a tailored dietary intervention should be applied for women with insufficient nutrient intake.

A $2{\times}3$ factorial arrangement of treatments was used in a completely randomized design to determine the effects of dietary Zn on performance and immune response of acutely endotoxemic growing pigs (n=96, mean BW=24.9 kg). Factors included 1) intramuscular injection of $10{\mu}g/kg$ BW of Escherichia coli lipopolysaccharide (LPS) or control and 2) supplemental Zn at 10, 50, or 150 ppm. Diets were fed beginning after weaning (initial body weight=7.6 kg) in the nursery and continued for 16 d into the grower phase. The basal corn-soybean meal grower diet contained 1% lysine and 34.3 ppm Zn. Pigs were acclimated for 12 d in the growerfinishing facility before LPS treatment on d 13. Gain, feed intake, and feed efficiency were unaffected by dietary Zn. Feed intake decreased (p<0.10) and gain/feed was greater (p<0.10) from d 13 to d 16 for pigs injected with LPS. Serum Zn and alkaline phosphatase activity increased (p<0.05) with increasing Zn levels. The febrile response to LPS peaked at 6 h post exposure and pigs were afebrile within 12 h. Rectal temperature was greater (p<0.05) in pigs receiving 50 and 150 ppm Zn than in pigs supplemented with 10 ppm Zn. In vivo cellular immune response, measured on d 13 by skin thickness response to phytohemagglutinin (PHA), was greater after 6 h (p<0.05) in pigs fed 10 ppm Zn and exposed to LPS compared to all other treatments, but was not affected at 12, 24 or 48 h. Zinc did not affect mitogen induced lymphocyte proliferation. Zinc supplemented at 50 or 150 ppm resulted in an enhanced febrile response in pigs subjected to iatrogenic endotoxemia, but did not affect pig performance or immune response measurements.

This study estimated the heavy metal concentrations in octopus (Octopus minor) and conducted a food safety assessment of octopus. Octopus, a benthic cephalopod, was collected from the Seosan intertidal zone on the west coast of Korea. The samples were digested with acids, and then the cadmium (Cd), copper (Cu), and zinc (Zn) contents were analyzed using inductively coupled plasma mass spectrometry (ICP-MS). The Cd, Cu, and Zn range of concentrations in octopus were 0.06-19 (mean 5.8), 44-1,463 (mean 354.8), and 76-929 (mean 247.9) mg/kg on a dry weight basis, respectively. The concentrations of heavy metals were higher in the internal organs than in the mantle. Of the three heavy metals, copper had the highest concentrations in the internal organs because of the existence of hemocyanin bound with copper in octopus blood, whereas zinc had the highest concentrations in the mantle. No relationship between the concentration of heavy metals and biological parameters (length, weight, and sex) was found. The ratios (I/M) of the heavy metal concentrations in internal organs and mantle were highest for cadmium, although cadmium had much lower concentrations in the internal organs compared with copper and zinc. Considering the provisional tolerable weekly intake (PTWI) of the three heavy metals and the average intake of octopus per day, all three elements should have no adverse effects on humans.
