The purpose of this study was to assess the energy value of breakfast and its relation to total daily nutrient intake and serum lipid. Dietary intakes were evaluated through the 3-day dietary recalls(interview for 1day and self-report for 2 days) from 333 Korean urban adults aged 20-49 year. Serum lipids in fasting blood samples were measured form 98 of those 333 adults. Low energy breakfast(<15% of daily energy intake) was consumed by 22.6% of males and 18.5% of females. 59.4 of males and 43.3% of females consumed a breakfast of average energy intake(15-25% daily energy intake) ; and 18.1 of males and 38.2% of females consumed a significant contribution to a total daily nutrient intake. The daily nutrient intake except crude fiber and vitamin A, B, B, and C in males and except vitamin C in females significantly increased as the energy value of breakfast increased. The differences in energy and nutrient intakes at breakfast were not made up for by other meals. To make matters worse, the satisfactory-energy breakfast group took more energy at dinner compared with the low-energy and average-energy breakfast group took more energy at dinner compared with the low-energy and average-energy breakfast groups in females. Among serum lipid parameters, TG was negatively correlated with energy provided at breakfast, and total cholesterol and LDL-cholesterol had a negative correlation with energy and carbohydrates provided at breakfast in males. For females TG was positively correlated with the ratio of carbohydrates to energy at breakfast but negatively correlated with the ratio of fat to energy at breakfast. These results suggest that satisfactory energy intakes at breakfast have positive effects on the adequacy of daily nutrient intake and may positively affect the serum lipid status.

The daily food intake and its related factors of the elderly(aged over 60) living in Incheon were compared. Self administered questionnaires were collected from 418 elderly. Statistical data analysis was completed using a SPSS v. 10.0 program. The results are summarized as follows: About 70% of elderly took grains and starch foods relatively high. The daily intakes of them was significantly influenced by ages of elderly, self-perceived health status, degree of drinking, meal regularity and nutritional balance of meals. More than 80% of elderly responded to take the food group of meat, fish and eggs poorly. Among various factors, the residence type and snack intake frequency influenced the daily intake of those foods statistically. A half of elderly took the vegetables and fruits everyday more than average. The daily consumption of vegetables and fruits was significantly influenced by sex, ages, exercise, snack intake frequency and preference of spices. Most elderly consumed fewer servings of milk and dairy products. About 60% of them did not take milk and dairy products daily. The daily contribution of those foods was significantly influenced by residence and exercise. 45.5% of elderly took oils and sugars more than average everyday which was influenced significantly by residence, exercise, snack intake frequency and meal regularity. In conclusion, the important influencing factors on the daily food intakes of elderly might be related to ages, residence, family, smoking, drinking, exercise, snack intake frequency and meal regularity. Therefore, a situation-oriented and practically organized nutrition education and ingestion support programs which consider the elderlies' socioeconomic status may help to improve the daily food intake of elderly in Incheon area.

The purpose of this study was to investigate differences in the body composition, dietary habits, daily intake of nutrients and clinical blood indices in female college students by body mass index of normal weight, overweight and obese. The subjects of this research were 141 respondents of a survey carried out on students, and subjects were given 60 minutes to answer questionnaires, by recording their own answers. The average heights and weights of subjects by BMI were 162.17 cm, 52.73 kg in normal weight group, 162.35 cm, 62.22 kg in overweight group and 161.72 cm, 69.82 kg in obesity group, respectively. As for the survey daily of meals, starving breakfast and kind of snacks of subjects were significantly different among the groups by BMI. In animal protein food intakes, meat intake was the highest 'every day' food consumed by subjects, and there was a significant difference in distribution of BMI among subjects. Fruits, and greenish and yellow vegetables intakes were the highest 'every day' foods indicated by the normal weight group. Consumption of carbonated beverages and juices showed a significant difference among groups by BMI. The average of total-cholesterol was the overweight group was the higher value. There was a significant difference in diastolic blood pressure and systolic blood pressure among the groups by BMI. Average daily calories intake levels were insufficient and the intake ratio of carbohydrates, protein, and fat was the normal weight group 68 : 17 : 15, the overweight group 64 : 18 : 18 and the obese group 73 : 14 : 13. Results of the daily vitamin intake analyses displayed riboflavin, niacin, vitamin C, and folic acid levels lower than the RI levels. Fe intake was the normal weight group 81%, overweight group 76%, obese group 59% of the RI level. Therefore, it is necessary for college students to establish regular meals, good quality snacks and consuming more vitamin and mineral nutritions for optimal health conditions.

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.

The purpose of this study was to estimate daily intake of manganese in Korean adults. Manganese intake was estimated through the use of the database of manganese content in frequently consumed Korean foods after first conducting anthropometric measurement and a survey on dietary intake with 354 Korean adults. Average age, height, weight and body mass index were 54.6 years, 165.7 cm, 67.2 kg and $24.5\;kg/m^2$ in males and 53.8 years, 153.7 cm, 59.1 kg and $24.9\;kg/m^2$ in females. The daily energy intakes of subjects were 1740.1 kcal in males and 1432.6 kcal in females. Male and female subjects recorded, respectively, 5.2 mg and 4.1 mg in manganese intake indicating that the male subjects consume more manganese (p<0.001). And they posted, respectively, 3.0 mg and 2.9 mg in manganese intake per 1000 kcal of energy consumption; it turned out that there was no significant difference. Daily manganese intake of both males and females posted, respectively, 148.8% and 135.2% of the adequate intake, and 8 males and 3 females surpassed the tolerable upper intake level. It is suggested that the study for accurate determination of manganese consumption needs to be more diversified based on the database of manganese content in Korean foods.

This study was designed to estimate the sodium intake of preschool children . To determine the sodium intake & excretion of preschool children in Korea, dietary behaviors, anthropometry, intakes of dietary nutrients, urinary sodium excretion and preference for salty foods were measured in 42 preschool children (male 26 , female 16, average6.5 years old) and their mothers. The results are summarized as follows. Mean daily urinary sodium excretion was 52.7 mEq(1,212.1mg). This value did not show remarkable change compared with the other studied that were accomplished in the similarage group for about the last ten years. And the subjects showed lower preference for salty taste than those of elementary school children and adults. Mean daily lower preference for salty taste than those of elementary school children and adults. Mean daily urinary sodium excretion were significantly correlated with the frequency of eating out (p<0.01), potassium intake(p<0.001) and urinary sodium to potassium excretion ratio(p<0.001). But there weren't any correlations with mean daily sodium intake, blood pressure, dietary nutrients intake and the preference for salty taste.

The purpose of this study was to estimate the daily manganese (Mn) intake of Korean children. This study was done using a three-day dietary intake survey of 257 Korean children (boys 123; girls 134). The Mn intake values were calculated based on a database that provides the Mn content of the frequently consumed Korean foods, alongside the food composition table provided by the Korean National Rural Living Science Institute. The average age, height, weight and body mass index of our subjects were 11.9 years, 155.4 cm, 48.9 kg and 20.2 kg/$m^2$ in boys and 11.9 years, 154.1 cm, 43.5 kg and 18.3 kg/$m^2$ in girls. The average daily energy intakes were 2,249.2 kcal in boys and 2,044.5 kcal in girls. Boys consumed significantly more Mn than girls, based on intake estimates of $4,585.3{\mu}g$ (117.6% of adequate intake) and $4,029.3{\mu}g$ (117.1% of adequate intake), respectively (P < 0.001). Boys had a Mn intake of $2,041.1{\mu}g$ per 1,000 kcal of energy consumption, whereas for girls this was at $1,983.9{\mu}g$ per 1,000 kcal. Neither group exceeded the tolerable upper intake level for Mn. The major food groups which contributed to Mn intake in our subjects were cereals (50.8%), vegetables (21.0%), seasonings (8.9%), and pulses (7.7%). Notably, boys derived a higher Mn intake through cereals and vegetable than did girls (P < 0.001, P < 0.05). The key food sources of Mn, in descending order, were rice, soybean curd, kimchi, black rice and cereals. We propose that the results of our study may be used as a basis for follow-up studies that examine the Mn intake of children.
