  • This study was performed to investigate the adequacy of dietary fat and protein intakes among female college students. Daily intakes of energy, fat, protein, major amino acids and other nutrients were measured in 52 female college students. Daily energy intake was 75.8% of the recommended intake. Fat and protein consist 19.2% and 16.7% of the total calorie, respectively. The average protein consumption per day was 105% of the recommended intake. Essential amino acids intakes were more than the recommended amounts which appears in the 6th edition of Recommended Dietary Allowances for Koreans. However, when the intake of each essential amino acid was compared to the recommended amino acid requirement pattern, these subjects did not meet the estimated requirements. There was a highly significant correlation between daily protein intake and lipid intake implying the major sources of protein in the diet were also major sources of fat. Daily intakes of dietary fiber, vitamin C, iron, and phosphorous were above the recommended levels of intake. However, blood hemoglobin concentration was marginal indicating dietary iron consumption is not a good marker for iron status. Also, calcium intake was only 63.5% of the recommended intake. Therefore, these results imply that main problems for these subjects are low energy consumption, low calcium intake, and the quality of protein. However, as opposed to the hypothesis, the main energy sources were not the food items high in saturated fats such as instant foods, which should be emphasized further.

  • This study investigated the correlation between consumption of sugar intake by fifth grade students in primary schools and development of Attention Deficit Hyperactivity Disorder (ADHD). A total of 107 students participated, and eight boys and one girl (8.4% of the total) categorized as high risk for ADHD according to diagnostic criteria. There were significant differences in the occupations and drinking habits of the respondents' fathers between the normal group and risk group. In a comparison of students' nutrition intake status with daily nutrition intake standards for Koreans, students consumed twice as much protein as the recommended level, whereas their calcium intake was only 60% of the recommended DRI (dietary reference intake). Regarding intake volume of vitamin C, the normal group posted 143.9% of the recommended DRI, whereas the risk group showed only 65.5% of the recommended DRI. In terms of simple sugar intake from snacks, students in the normal group consumed 58.4 g while the risk group consumed 50.2 g. These levels constituted 12.5% of their total daily volume of sugar intake from snacks, which is higher than the 10% standard recommended by the WHO. In conclusion, children who consumed less sugar from fruit snacks or whose vitamin C intake was less than RI was at increased risks for ADHD (P < 0.05). However, no significant association was observed between total volume of simple sugar intake from snacks and ADHD development.

  • Objectives: Although water is essential for life and can supply essential minerals, studies that evaluate calcium intake through drinking water are limited. The aim of this study was to assess calcium contents of natural mineral water (NMW) and its possible contribution to calcium intake in healthy adults. Methods: This study examined water consumption in 640 Korean adults with self-selected diet, analyzed the calcium content of 10 different brands of bottled NMWs sold in Korea, and assessed the amount of calcium intake from drinking water and its daily contribution to the recommended nutrient intake (RNI) of calcium. Results: Mean calcium content in 10 bottled NMWs was 20.9 mg/l. Daily water intakes from food composition database and calculated using energy intake based on 0.53 ml/kcal were 957.2 ml and 1109.8 ml for men and 848.3 ml and 951.6 ml for women, respectively, with a significant difference by gender (p<0.001). Daily drinking water intake was significantly higher among men than women (1203.9 ml vs. 1004.3 ml, respectively, p<0.001). Daily calcium intakes from foods were 564.0 mg for men and 534.2 mg for women. Daily possible calcium intakes from drinking bottled water were 25.2 mg for men and 21.0 mg for women (p<0.001). The contribution of daily calcium intake from drinking bottled water to RNI of calcium was 3.3% for men and 2.9% for women without significant difference. Conclusions: One half of the daily total water intake was consumed as drinking water, and possible calcium intake through drinking water was about 3% of RNI.

  • This study was conducted to investigate sodium and potassium balances, as well as correlations among the relating factors in adult males and females. We collected blood, urine and feces samples as well as a dietary intake survey from 50 subjects. Then, we analyzed the sodium and potassium contents in blood, urine and feces, and evaluated their state of balance. The average ages of the study targets were 24.7 years old for males and 22.8 years old for females. The daily energy intake by the males was 1733.4 kcal and by the females was 1570.3 kcal. Sodium intakes were 138.3 mEq and 127.5 mEq for males and females, respectively. Potassium intakes were 43.1 mEq and 49.3 mEq, respectively. The daily excretions of sodium through urine were 136.6 mEq by males and 97.0 mEq by females and the excretions through feces were 2.2 mEq and 2.0 mEq, respectively. The daily excretions of potassium through urine were 20.2 mEq and 16.5 mEq by males and females respectively, and the excretions through feces were 7.7 mEq and 7.5 mEq male to female. The retention rates of sodium were 11.7% and 14.1% male to female, respectively, and the apparent absorption rates were 98.5% and 97.8%. Additionally, the retention rates of potassium were 32.9% and 39.8% and the apparent absorptions were 81.9% and 81.3%, both male and female. It was noted that, overall, the sodium intake of adult males and females is still higher than the recommended daily sodium intake, while the potassium intakes and excretions were found to be lower. Based on the results of this study, nutritional guidance and education is recommended to encourage decreased sodium intake and increased potassium intake, according to recommended standards.

  • Purpose: The purpose of this study was to identify the relationship between energy intake and fatigue in cancer patients receiving chemotherapy. Methods: A total of 106 subjects had participated in this study. Data were collected at a university hospital in D city from September 1st to November 10th, 2010. Energy intake including carbohydrates, protein and fat was measured by scale and analyzed using Can Pro 3.0 program. Fatigue level was measured by the Revised Piper Fatigue Scale. Data were analyzed using descriptive analysis, t-test, ANOVA and Pearson correlation coefficient with SPSS/WIN 15.0. Results: The mean calorie intake during chemotherapy was $906.53{\pm}201.28Kcal/day$ which was 45.3% of the recommended daily calorie intake. The mean of protein intake level was $43.62{\pm}11.13g/day$, and it was low compared to the recommended daily protein intake. Calories, carbohydrates, and protein levels on 3rd day after chemotherapy were significantly lower than those of 2nd day after chemotherapy (p<.001). The fatigue level during chemotherapy was $5.77{\pm}0.77$ which was moderate level of fatigue. There was a significant negative interrelation between energy intake and fatigue. Conclusion: Theses results suggested that nursing approaches to encourage dietary intake may be helpful to reduce fatigue for cancer patients receiving chemotherapy.

  • According to the data published in 1990s on the intake of dietary fiber(DF) of Korean, DF intake of Korean has been gradually decreasing in the last two decades. Mean daily intake of DF in 1990s is estimated to be in the rage of 17-20g per capita and over seventy five percent of the subjects examined appeared to consume DF less than 20g per day. The major food sources of Df in Korean diet include cereals, vegetables, fruits, seaweeds and seasonings. The present level of DF intake of Korean is lower than the tentatively recommended minimum intake of DF. It is predicted that, if the present trend of change on food consumption pattern is maintained, the gradual increases in the incidence of chronic degenerative diseases will be continuing. Therefore, the beneficial effects of DF on health care and disease control should be emphasized through the nutritional education and high level consumption of DF needs to be strongly recommended in the dietary guideline. In order to raise the daily consumption of DF, more whole grain cereals need to be used as a part of staple and more frequent intake of legumes and seaweeds is required as well as the development of high-fiber diet recipes and natural high-fiber products.

  • The purpose of this study was to analyze average kimchi intake, general characteristics, frequency of daily meal intake, intakes of vegetables and fruits, and nutrient intakes in four serving size groups based on data from the Korea National Health and Nutrition Examination Survey 2010~2012. The results showed an average amount of kimchi intake in subjects of 115.6 g, ranging from 0 g to 605.94 g. For daily meal intake except snacking according to kimchi serving size, all daily meal intakes increased significantly with increasing kimchi serving size (p<0.0001), and tendency of kimchi intake increased with more eating-out. As kimchi serving size increased, total intakes of vegetables and salted vegetables increased significantly (p<0.0001). However, unsalted vegetables intake did not show significant difference. Intake of fruits also increased with increasing kimchi serving size. As the serving size of kimchi increased, intakes of energy, carbohydrates, protein, fat, sodium, and potassium increased significantly (p<0.0001). For intake of sodium, intakes of all groups exceeded 2,000 mg, which is the recommended level for Koreans. Moreover, the fourth serving size group consumed three times (6,546.35 mg) more sodium than the recommended level.

  • The dietary vitamin $B_6$ intake of 218 Korean young women (aged 20-26y), who had no health problems, and their sources were estimated using a modified Korean vitamin $B_6$ database. The average daily vitamin $B_6$ intake was 0.987 mg for the subjects. About 87.2% of the subjects consumed less than the Korean Recommended Dietary Allowance (RDA) of vitamin $B_6$. The average ratio of vitamin $B_6$ intake to daily protein intake was 0.014 mg/g protein, and approximately 91% of subjects consumed 〈 0.02 mg/g protein. Vitamin $B_6$ intake was significantly (p〈.01 -p〈.001) positively correlated to the intakes of all other nutrients. Between animal and vegetable protein, animal protein had a stronger positive correlation with vitamin $B_6$. Major dietary sources of vitamin $B_6$, the top 10 foods provided nearly 64% of total vitamin $B_6$, and dietary contributors of vitamin $B_6$ for Koreans are less varied than those for Americans.

  • Three-day dietary records data from 237 college students(male 65, female 172) were used as the basis to estimate total dietary fiber(DF) intake of Korean adults & to investigate the major food sources of fiber. Mean daily DF intake of the subjects was 15.2$\pm$3.7g range being 7.5-34g When related to energy intake women consume more DF(7.7$\pm$1.5/1000kcal) than men(6.8$\pm$1.7g/1000kcal) Mean daily crude fiber(CF) intake of the subjects was 6.2$\pm$2.4g The mean DF:CF ratio for the subjects was 2.5$\pm$0.5 indicating that DF intake is 2-3 times of CF intakes The intakes of the two measures of fiber were highly correlated(r=0.791) The major food sources for DF in Korean are vegetables cereals and fruits and 14.3% respectively In comparision with limited international data on the DF intake by adults DF intake by the subjects was similar to those of developed countries. Present study indicates that DF intakes of the subjects are considerably lower than recommended level and they need to consume more DF than the present level.

  • This study compared the nutrient intake of obese versus non-obese non-insulin dependent diabetes mellitus (NIDDM) patients for Diabetes Medical Nutrition Therapy. The study was conducted at medical hospitals in Gyeonggi and Seoul from April 2009 to November 2009. Fifty-six adult male NIDDM patients were enrolled and divided into two groups: 36 into an obese group (BMI ${\geq}25$) and 20 into a non-obese group (BMI<25). To conduct this study, anthropometric measurements, and daily nutrient intake of obese and non-obese NIDDM patients were measured. Daily nutrient intake was estimated by 24hr-recall and analyzed by the CAN program. In the results, anthropometric measurements of the two groups showed significant differences in weight and BMI (p<0.001). Daily nutrient intake of the two groups showed no significant differences, except for vitamin E intake (p<0.05). The total energy intake of the non-obese and obese groups were $2,669.9{\pm}964$ kcal and $2,555.4{\pm}803$ kcal, respectively, which were both above 113% of the recommended Dietary Reference Intakes for Korean (KDRIs). Cholesterol and sodium intake were $378.1{\pm}215.6$ mg and $6,478.9{\pm}2755.1$ mg, respectively for the non-obese group. Cholesterol and sodium intake were $308.1{\pm}155.6$ mg and $6,306.8{\pm}2788.9$ mg, respectively, for the obese group. Both groups were above 150% of the recommended levels set by the Korean Diabetes Association (KDA). However, their antioxidant nutrient intake was appropriate. Meanwhile, their fiber intake was $10.7{\pm}5.1$ g and $9.8{\pm}5.2$ g, respectively, which was lower than 40% of the recommended intake set by the KDA. The results show that the nutritional education for obese and non-obese NIDDM male patients must aim to reduce total energy, cholesterol, and sodium intake, while increasing fiber intake. In addition, the factors related to a patient's glycosylated hemoglobin, serum lipids, blood pressure, and weight change must be calibrated for the appropriate energy, fat, cholesterol, sodium, and dietary fiber intake.
