The purpose of this study was to develop the website-based program for individual meal planning. The program consisted of the basic information of clients, dietary habits, analysis of nutrient intakes and menu planning. The first part of the program consisted of general information such as general characteristics and anthropometric data of clients. The second part was designed to investigate the dietary habits, food intake frequency, nutrition knowledge, and drinking and smoking habits of the clients. The third part consisted of analysis of nutrient intakes including three major nutrients, calorie intake by foods and alcohol, and ratio of individual fatty acid intake. Nutrient intakes was evaluated by comparing with dietary reference intakes. In the final part, the program included the menu planning by using standard recipe. This system was also designed to insert, remove or change the food items or amount according to the user need. It is expected that the development of a meal planning system based on the internet can facilitate the professional dietary counseling, and thus help to improve the health of people.

Food and feeding habits of large cyprinid fishes (Labeobarbus intermedius, Labeobarbus nedgia, and Labeo forskalii) had been investigated in the upper Blue Nile River, Ethiopia. Four sampling sites were selected and specimens were sampled during the post-rainy (November 2016) and dry (March 2017) seasons by gillnets of 6 cm, 8 cm, 10 cm, 12 cm, and 14 cm mesh sizes. Totally 401 fishes were collected and about 30.4% (122) of the samples were documented with empty guts and 279 (69.6%) of them were with non-empty guts. The whole contents of all non-empty gut specimens were taken, labeled, and preserved using a 5% formaldehyde solution for further analysis. In the laboratory, gut contents were examined and identified using compound and stereo microscopes. The relative importance of different food items in the diet compositions was analyzed using a frequency of occurrence and volumetric analysis. During the post-rainy season, insects and phytoplankton were mostly ingested as food items. However, during the dry season, phytoplankton was the most important food item in the diet of all cyprinid fishes of the river. Based on current study results, L. intermedius and L. nedgia might be omnivores in their diet but Labeobarbus forskalii seemed to be detritivorous.

Malnutrition is a common problem in patients undergoing maintenance hemodialysis(HD) and compromised food intake is an important cause. Malnutrition is one of the important factors influencing mortality in chronic HD patients. We investigated the nutritional parameters of 50 Korean HD patients(mean age: 46.9 $\pm$ 10.3y, men : 23, women : 27) by measuring anthropometric and biochemical blood indices and assessing food intake using 24-h recall method. Also we administered two questionnaires, one for assessing nutritional knowledge about renal disease and dietary therapy, the other for measuring dietary habits related to dietary therapy. According to the distribution of BMI, 21.3% of HD patients were underweight. The hematological values of HD patients, such as plasma hemoglobin, hematocrit, and total lymphocyte count were below the normal range. The serum cholesterol levels were 133.2 $\pm$ 30.5mg/dl. HD patients took energy and protein only 77.5% and 83.1%, respectively, of their RDA. There were significantly positive correlations between nutritional knowledge and intake of nutrients, such as energy, fat, cholesterol, iron, potassium, vitamin B$_1$, vitamin B$_2$, and niacin. Also, there was a significantly positive correlation between nutritional knowledge and dietary habits(r = 0.317, p < 0.05). In conclusion, Korean HD patients showed mild malnutrition and suboptimal nutrition intake. It can be postulated that the dietary intake can be increased by nutrition education improving nutritional knowledge and correcting the dietary habits of HD patients.

This study was conducted to investigate the effect of two-year course of food and nutrition on improving nutrition knowledge, dietary attitudes and food habits of junior college female students by questionnaires. The subjects were 108 college female students enrolled in the department of food and nutrition in Gyeonggi area. The results were as follows: There were no significant changes in the weights and BMI (Body Mass Index) after 2-yr course of food and nutrition. Nutrition knowledge (14.7 vs 16.3, p < 0.001) and dietary attitude (34.3 vs 35.8, p < 0.01) increased significantly after 2-yr course. However, no significant changes in food habit were observed. Among nutrition knowledge, the scores of functions (4.5 vs 5.2, p < 0.001) and understanding (6.7 vs 7.4, p < 0.01) of nutrients were significantly increased. The recognition of nutrition knowledge increased significantly (83.1 vs 95.7, p < 0.001). Among food habit, dietary habit (13.2 vs 12.5, p < 0.01) and health related habit (15.6 vs 14.6, p < 0.001) were significantly lowered after 2-yr course. The change in dietary attitudes showed significantly positive correlation with food habit changes (p < 0.05). These results showed that 2-yr course of Food and Nutrition had improved the nutrition knowledge and dietary attitudes. Therefore, providing the more systematic and appropriate nutrition education to students during their study period will be improved dietary attitudes and food habits.

The questionnaires answered by 832 college students were analyzed for nutrition knowledge, food habits, and the sources of nutrition information. The students had a high level of perceived knowledge(88%), that is the knowledge that each subject believed he had, but the accuracy of the knowledge was only 55%. The mean score of nutrition knowledge was 7.20 out of possible 15.0 points and the mean food habit score was only 3.90 out of possible 10.0 points. And 59% of the subjects belonged 'poor food habit' group. The female subjects showed higher scores than male students in the perceived knowledge, the accuracy of the knowledge, the mean nutrition knowledge score, and the food habit score. There was a high correlation between nutrition knowledge score and food habit score of the subjects. The male students ranked mass media, high school courses, and parents as their primary sources of nutritional information, while 78% of female subjects ranked high school courses as their first choice of nutritional information.

A checklist of dietary behavior items for the elderly was developed based on Korean dietary guidelines. First, a literature review was conducted, and 63 preliminary items, including 30 items on food intake, 12 on eating habits, and 21 on dietary culture, were obtained to evaluate the dietary guidelines. The preliminary items were evaluated by experts using Lawshe's method to verify the content validity. They were then revised, resulting in 52 items: 25, 11, and 16 in the food intake, eating habits, and dietary culture domains, respectively. A face-to-face survey was conducted on 331 people over 65 years of age in the metropolitan area, and their one-day food intake was surveyed using a 24-hour recall method in August 2022. The 48 items, including 24, 11, and 13 items on food intake, eating habits, and dietary culture, respectively, correlated significantly with the evaluation indicators of nutrient intake, such as mean adequacy ratio, dietary diversity score, and nutrient intake density. These items were considered suitable for evaluating the elderly's compliance with dietary guidelines.

To investigate the importance and practice of well-being related dietary life pattern such as purchasing food materials, food habits and eating out, a survey was conducted by questionnaire and 5-point Likert score in Seoul and Gyeonggi-Do, September, 2004 and April, 2005. The responses of 732 housewives who were over 40 years were analyzed by SPSS package program. The results were as follows. Most of them were 40-49 years(74.4%), graduated highschool (66.6%) and their family type was nuclear family type(81.4%). Almost half of them had full-time job (37.1%) and part time job (15.4%). The average importance score of 'food habits', 'purchasing food materials' and 'eating out' were $4.15{\pm}0.91,\;4.06{\pm}0.96\;and\;3.25{\pm}1.01$ respectively. But the average practice score of 'food habits' was greater($3.58{\pm}1.06$) than 'purchasing food materials ($3.19{\pm}1.19$)' and 'eating out($2.54{\pm}1.05$)'. Among 5 types of 'food habits', the type of 'cut down on eating fast food' had the greatest score of importances ($4.31{\pm}0.97$) but the difference between importance and practice was greatest(0.94). Also 'consume home-made food rather than processed or ready to food' showed great scores in importance ($4.28{\pm}0.87$) and practice($3.87{\pm}1.04$). 'Consume fruits and vegetables rather than meats' and 'avoid heavy use of oils' had the importance score of $4.04{\sim}4.19$. But the practice score of 'avoid heavy use of oils' was the lowest($3.39{\pm}0.97$). Among four types of purchasing of food materials, 'purchase domestic agricultural food' was greatest($4.37{\pm}0.78$) and 'don't purchase genetically modified food' 'purchase organic food' and 'purchase whole grain products' were also great ($3.92{\sim}3.99$). But the practice score of 'purchase organic/low chemical foods($2.77{\pm}0.98$)' and 'don't purchase genetically modified food($2.99{\pm}1.41$)' were lowest. 'Go to well being restaurant' in three types of 'eating out' showed greatest in importance($3.35{\pm}0.96$) but the practice score($2.47{\pm}0.10$) was lower than the importance score. Also 'choose menu with comparing calories' had the lower score in practice($2.45{\pm}1.06$) rather than importance score($3.22{\pm}1.03$). In regarding to 'food habits', the importance score were significantly affected by type of food expense (p<0.05) and health status (p<0.05). The importance score of 'purchase food materials' were significantly affected by the type of food expense (p<0.001), type of residence(p<0.05), and self assessment of weight(p<0.05). Monthly income, especially more 400 million won, was the commonly significant effector in practice score of 'purchase food materials' and 'eating out'.

In this study, we investigated the dietary habits, snacks, and self-purchasing snacks (SPS) intake behaviors of 519 elementary school students (boys=239, girls=280). Obesity was significantly higher (p<0.05) in boys (24.8%) than in girls (14.7%) and the proportion of underweight subjects was higher compared to normal or other weight groups for both the boys and the girls. There were 7.5% of the subjects in the group that always skipped breakfast, and the main reason of skipping breakfast was insufficient time (51.9%). The snack intake frequency was once or twice per week for 23.1% of the subjects and three or four times per week for 25.1%. The SPS intake frequency was the subjects zero for 35.6% of the highest level of the responders, while 6.8% of the respondents took more than once SPS per day. 59.6% of the respondents consumed SPS due to hunger while 15.0% consumed SPS out of boredom. The SPS was purchased from supermarkets in 34.5% of the cases, from convenience stores in 24.1% and from snack corners in 20.0% of cases or from a store near school in 14.5% of the cases. Analysis of SPS behaviors according to obesity index showed that parent's opinion of 'permission to buy SPS as needed' had a significant effect in 64.5% over weight subjects compared to only 53.7% in underweight groups. The subjects who used more than 3/4 of their pocket money to buy SPS was higher in the overweight groups (16.4%) than in the underweight groups (7.0%) and normal weight groups (9.8%). The favorite snacks and SPS were milk and yogurt for 45.7% of the subjects, fruits for 42.7%, ice cream for 26.4%, fruit juices for 23.8%, sweet stuff for 16.4%, frozen dessert for 8.9%, and chocolate or candy for 8.1% in descending order. The intake frequency of milk, yogurt, and fruit juices was higher in the underweight groups, but the intake frequency of sweet stuff, frozen dessert, and chocolate or candy was higher in over weight groups. The intake of frozen dessert was more than four times higher in the overweight groups than in the underweight groups. In conclusion, dietary habits, snacks, and SPS intake behaviors were similar between the boys and the girls and obesity groups, but most students appeared to have a high preference for intake snacks and SPS. Therefore, education for appropriate snacks intake habits will be beneficial for improving their dietary habits and health.
