This study was conducted to investigate the validity of using a cameraphone for a dietary intake survey method. The subjects were 28 female college students. After eating a standard lunch meal which consisted of plain rice, seaweed soup, bulgogi, cucumber salad, roasted anchovy and kimchi, the quantity of dietary intake, calorie intake & nutrients intake were analyzed by weighed method, diet record method and cameraphone method by dietitian with k without cameraphone analysis training. There were no significant differences in the quantity of 6 foods intake between weighted method and cameraphone method by dietitians with camera phone analysis training. However, the quantity of seaweed soup, bulgogi & cucumber salad intake analyzed by diet record method was significantly lower than the weighed method. And the quantity of seaweed soup, bulgogi, cucumber salad, roasted anchovy and kimchi intake analyzed by the cameraphone method by dietitians without cameraphone analysis training was significantly lower than the weighed method. There were no significant differences in the calorie intake and nutrients intake between the weighted method and camera phone method by dietitians with camera-phone analysis training. However, protein, calcium, iron, phosphorous, Vitamin A, Vitamin $B_2$, Vitamin E and cholesterol intake analyzed by diet record method was significantly lower than the weighed method. And fat and Vitamin $B_2$ intake analyzed by the camera phone method by dietitians without cameraphone analysis training was significantly lower than the weighed method. Therefore, this study suggests that the use of the camerephone may be a valid and convenient method fur evaluating a dietary intake survey. However, systematic and standard education is necessary about the size and volume of dishes and angle of photo for more accurate results.

This study used survey data to identify the use of salimeters and the prevalence of sodium reduction education in the Gyeonggi region. A survey with 211 dietitians working in school foodservice (106 in elementary schools, 69 in middle schools, and 36 in high schools) was conducted from August 6 to August 17, 2012. The data were analyzed using the SPSS program. Though 86.6% of school kitchens had salimeters, the rate for checking the sodium content of soup or stew was just 62.7% and the rate for checking the sodium content of kimchi and solid food was very low. Since salimeters are mostly used to measure sodium in liquid foods, it is urgent to provide an education and manual on using salimeters and to promote salimetry for kimchi and side dishes. It is also important to provide students with nutritional information by clearly posting the sodium content of food on menus and compelling students to notice them. Sodium reduction education for cooks was conducted in the 70.3% of the kitchens; however, the dietitians perceived that the cooks did not understand the importance of the education. Also, sodium reduction education for students was mostly provided through indirect methods, rather than face-to-face education, resulting in poor educational data (only 36.4% comprehending). By providing detailed guidelines for sodium reduction and labelling accurate content of sodium of the menus, we will be able to enforce practices for sodium reduction in school lunches.

The purpose of this study was to evaluate the meal pattern and the nutritional balance in university foodservices of Seoul. The survey was conducted using a questionnaire with 317 students at five different cafeterias that served 23 meals. We weighed all the meals offered by the university foodservices, separated the foods, and calculated their nutritional content using a computer program $\ulcorner$DS24$\lrcorner$. We also checked the dishes and those amount students consumed from the menu. The results of this study is summarized as follows. : 1) The most prevalent menu patterns included rice, soup, two side dishes, and kimchi. 2) Most nutrient contents per meal in a given menu was lower than one third of the recommended dietary allowance(RDA). 3) The mean energy content for the amount of rice that was served was 399㎉, for the side dish, it was 107㎉, and for the kimchi, it was 9.9㎉. 4) The number of total dishes and side dishes was five and two, respectively. The dietary variety score was 16.7, and the dietary diversity score was 3. 5) The mean energy intake by students at self-operated managements were 545㎉, and at one contracted management, the energy intake were 494㎉. Both of them did not serve enough to meet one third of the RDA. Nutrient adequacy ration(NAR) was 0.4∼0.9, and Index of nutritional quality(INQ) was above 0.9 for most nutrients with the exception of calcium and vitamin B$_2$.

To find out what foods and dishes are being consumed by people with dyslipidemia, we have researched which food groups and dish groups are utilized in order to use for nutrition educations. The data was obtained from participants in 2001 KNHNS using the 24hours recall method. Ages over 30 years old are used for the analysis. Food and dish group intakes are analyzed by gender, age, residence, education, and economic status. Dyslipidemia are divided into A, B and C groups using guideline of dyslipidemia. The differences in food consumption were analyzed and assessed by GMDVF, DDS and DVS. SAS and SPSS were used for the data analysis. Overall, In food group, people in B and C (with dyslipidemia) have higher intake levels of vegetables, while people in A (without dyslipidemia) have higher intake levels of fruits (p < 0.05). In dish group, people in B and C (with dyslipidemia) have higher intake levels of rice dish, soups and kimchi, while people A (without dyslipidemia) have higher intake levels of breads and snacks, salad and fruits (p < 0.05). In the dietary patterns of main food group (GMDVF), the pattern excluding dairy (11011) revealed the highest proportion in all groups. DDS = 4 has the highest proportion in all groups. The proportions of subjects with the low dietary diversity score increased in B and C (with dyslipidemia). Food groups that most people do not consume were dairy and fruits. The level of DVS in A (without dyslipidemia) is higher than in B and C (with dyslipidemia). With these results, it is shown that people with dyslipidemia had worse quality patterns of food intake than those without dyslipidemia. Thus we should emphasize the balanced diet and educate people how to choose foods. So it is necessary to develop food guide for people with dyslipidemia.

The dietary vitamin $B_6$ intake of 185 Korean children aged 7-12 years (y), who showed no health problems, in the Seoul area and its sources were estimated using a modified Korean vitamin $B_6$ database. The age and sex of each subject was classified according to the classifications in the Korean Recommended Dietary Allowance (RDA). Dietary vitamin $B_6$ intake and food sources were estimated using the three-day recall method with the help of a trained interviewer. Food portion sizes were estimated by using standard household measures and published average portion sizes. The average daily vitamin $B_6$ intake was 1.69$\pm$0.50 mg/d in children aged 7-9 y, 1.86$\pm$0.44 mg/d in male children aged 10-12 y and 1.77$\pm$0.62 mg/d in female children aged 10-12 y. Less than 5% of the subjects consumed less than the Korean RDA of vitamin $B_6$. The average ratio of vitamin $B_6$intake to daily protein intake was 0.028$\pm$0.006 mg/g in children aged 7-9 y, 0.028$\pm$0.004 mg/g in male children aged 10-12 y and 0.029$\pm$0.007 mg/g in female children aged 10-12 y. The intake of vitamin $B_6$ was significantly (p<.01) positively correlated to the intake of all other nutrients. Foods from animal and plant sources provided 37% and 73% respectively, of total vitamin $B_6$. Major dietary sources of vitamin $B_6$ in children in the Seoul area were rice, soybean sprouts, pork, beef, cereal, kimchi, milk, onions, and potatoes. As for major dietary sources of vitamin $B_6$, the top 20 foods provided nearly 73-75% of the total vitamin $B_6$ consumed by Korean children.

Dietary intakes and sources of vitamin B$_{6}$ in 72 healthy Korean elderly subjects (29 men,43 women, $\geq$57 years of age) living in the Seoul area were estimated using a modified Korean vitamin B$_{6}$ database. The dietary vitamin B$_{6}$ intake and food sources were estimated by the three day recall method with the help of a trained interviewer. Food portion sizes were estimated using standard household measures and published average portion sizes. The average daily vitamin B$_{6}$ intake was 2.06$\pm$0.46 mg/d in elderly men, and 1.94$\pm$ 0.47 mg/d in elderly women. Less than 5% of elderly men and 15% of elderly women consumed less than the Korean Recommended Dietary Allowance (RDA) of vitamin B$_{6}$. The average ratios of vitamin Be intake to daily protein intake were 0.03 $\pm$ 0.01 mg/g in both elderly men and women. The intake of vitamin B$_{6}$ was significantly (p <0.01 ∼ p<0.001) and positively correlated to intakes of all other nutrients in elderly women, but was not significantly correlated to intakes of several nutrients in elderly men. Foods from animal and plant sources provided 24% and 76%, respectively, of the total vitamin B$_{6}$. Major dietary sources of vitamin B$_{6}$ in Korean elderly were rice, soybean sprout, kimchi, pork, beef, potatoes, garlic, onion, anchovy and kochujang. The major sources accounted for most of the vitamin B$_{6}$ intake with the top 20 foods providing nearly 75∼76% of the total vitamin B$_{6}$ in Korean elderly./ in Korean elderly.
