This study was performed to assess the effect of eating behaviors and health-related variables on overall dietary quality. Ninety-four(male 21, female 73) elderly who were over 60 residing in middle income areas in Cheongju city participated. Information on general characteristics of the elderly, health-related life style, regularity of meal, meal balance and desirable eating habits were obtained by interview based on questionnare. Dietary nutrient intake data were obtained through the 24 hour recall method. The mean age and BMI of the subjects were 73.3 years old and 23.3(male 21.8 female 23.7) respectively. The proportions of underweight and hypertension were 19.2% and 36.2%. Most nutrients except vitamin $B_2$ and calcium were consumed over 75% of the RDA. The Mean Adequacy of Ratio(MAR) of nutrient intake was 0.64(male 0.72, female 0.62). The average score of regularity of meal, meal balance, and desirable eating habits was 14.4 out of a possible 16, 13.7 out of a possible 24 and 5.5 out of a possible 16 points respectively. Male than female, older subjects than young subjects, and those living with their spouses than with other family or living alone had better scores in eating behaviors. Smoking, chewing ability and eating alone vs eating with company affected overall of regulality of meal and meal balance(p<0.05). Positive correlation (p<0.05) was also dietary quality. There was a positive correlation between the mean adequacy ratio, score observed between scores in regularity of meal and meal balance. Therefore, the elderly should be encouraged to eat a variety of food, maintain good dental health, keep regularity of meal and have meals with company to help improve overall dietary quality and eventually achieve optimal nutritional status.

The purpose of this study was to evaluate nutrient intake and meal variety with breakfast eating in Korean adolescents using data from the 2008-2009 National Health and Nutrition Examination Survey. The analysis included 1245 adolescents aged 12 to 18 years. The subjects were divided into two groups according to breakfast skipping (BS: breakfast skipping, n = 235, BE: breakfast eating, n = 1110). The BS group was significantly higher in its frequency of eating soda drinks, instant noodle, and ice cream than the BE group. The BS group consumed significantly lower quantities of plant calcium and plant protein per 1,000 kcal compared to the BE group. Also the intake of cereal and vegetables in the BS group was significantly lower than those in the BE group, however, the intake of beverage in the BS group was significantly higher than that in the BE group. The average number of foods of the BE and BS groups were 29.50 and 25.85, respectively and revealed a statistical significance (p < 0.0001). The snack intake and % energy from snack intake of the BS group were significantly higher than those of the BE group. Also, the fasting blood glucose concentrations were significantly higher in the BS group compared to the BE group. In conclusion, adolescents who skip breakfast may have lower meal variety and higher blood glucose concentrations. Therefore, in support of proper dietary management, it is necessary to promote and encourage breakfast eating.

Seventy two Black Bengal goats on road side grass based diet were fed on 0, 20, 40, 80, 100 or 120 g of fish meal (FM)/goat/day with or without ad libitum access to urea molasses block(UMB). The purpose was to assess the interaction of undegradable protein (UDP) and fermentable nitrogen(N) supplementation on feed intake, nutrient digestibility and growth of goats. Live weight gain of goats increased linearly with the increasing of dietary fish meal as an undegradable protein source. With the increasing level of fish meal the live weight gain(g/day) was 17, 23, 46, 48, 48 and 52 with urea molasses block and 12, 21, 31, 49, 47 and 47 without urea molasses block. It was concluded that the beneficial effects of urea molasses feeding to accelerate the dry matter intake, TDN intake and nutrient digestibility observed could not be exploited in terms of live weight gain.

As the elderly population has increased in the advanced countries, food intake, relationship of nutrient intake and disease has become major problem in the aged. To investigate the dietary behaviors and the preference of food of the elderly for developing meal planning, the study was conducted through survey questionnaires including 24-hr dietary recall, dietary behaviors, food preference and frequency of food intake to 352 elderly (104 male and 248 female) who were more than 60 years old and living in Seoul. Most of subjects ate three meals regulary and the most preferred taste was sweet and the less preferred taste was sour. Dietary behaviors according to educational level were shown that the skipping meal time and duration time of one meal were significant difference in educational level. Most of the elderly subjects like kimchi and soybean paste soup. The more educated elderly were preferred milk. The reason of dislike of milk was bad flavor and diarrhea. Most of them who graduated from university and high school selected fishes because of good for health primary, otherwise no educated, elementary school and middle school graduated elderly selected vegetables primary. Meats, fishes, seaweeds, mushrooms, fruits, milk and milk products, eggs and vegetables intakes of total elderly subjects were significantly positively related to educational level. With respect to milk and milk products intakes, cheese, yogurt (curd) and milk intake of elderly was significantly negatively related to age. Therefore education for developing desirable dietary behaviors and improving the meal patterns should be in forced to elderly, especially who had poor educational background in order to manage the meal planning and to care for their health in the later life.

This experiment was conducted to determine the effect of dietary red pepper seed oil meal (RPSOM) on the performance and the fat pad content in broiler chicks. feeding trial was conducted with 360 birds broiler chicks for 8 weeks. The levels of dietary RPSOM were 0, 5, 10 and 15% and mixed in diet consisting of corn and soybean meal. Body weight, feed intake, feed conversion and mixed in diet consisting of corn and soybean meal. Body weight, feed intake, feed conversion and viability were not significantly different among treatments. The percentage of abdominal fat and skin color were not significantly differents among treatments. The results of the feeding trial show that RPSOM can be used within 10% in broiler diet.

The purpose of this study was to investigate effect of living condition and aging on food intake in Korea. 98 free-meal receivers and 81 members in well-being center for the aged were asked about their food frequency and food consumption and their socioeconomic status by a questionnaire. All data were analyzed by SPSS (Statistical Packages for the Social Sciences) 10.0 program. There were statistical differences of living condition, marital status, former job and teeth status between free-meal receivers and people with stable lives. Moreover, all age groups of free-meal receivers had lower income, living expenses, educational period and frequency of physical activity than those of people with stable lives. But smoking and drinking was much higher in free-meal receivers. Arthritis was the most prevalent disease in both groups. And free-meal receivers had higher blood pressure and lower Body Mass Index than people with stable lives. Food consumption of free-meal receivers was definitely lower than that of people with stable lives in terms of food frequency and standard amount of food eaten. But noodles, bean sprouts and eggs were very important foods for free-meal receives. Food consumption of the aged was affected by age, educational period, income, blood pressure, duration after retirement, frequency of physical activity and Body Mass Index. Therefore, as various socioeconomic status affects on food intakes of the aged, more effective and practical nutritional programs which consider the receivers'socioeconomic status are needed for the nutritionally at-risk groups like the aging free-meal receivers.

The average sodium intake of Koreans was reported to be 5,279.9 mg/day, which is one of the highest intake levels worldwide. The average Koreans intake 19.6% of sodium from kimchi, showing kimchi as the main contributor of sodium in this country (Ministry of Health and Welfare, 2005). The sodium content of dishes that are frequently chosen by workers, and which were served by foodservice cafeterias were chemically analyzed. The average sodium content of one meal provided by 10 foodservice cafeterias was 2,777.7 mg. Twenty-one, one-dish-meals, frequently chosen by workers for a lunch menu, were collected at 4 different restaurants for each menu by one male, aged in the twenties and analyzed chemically also. Workers who eat lunch at a workplace cafeteria everyday could intake about 8 g of salt at a one-time meal and those who eat out for a one-dish-meal would intake 3-8 g of salt without counting sodium content from the side dishes. From these study results, one could estimate that over 10 g of salt could be possible for a single meal for workers who eat out everyday. A nationwide nutrition campaign and education for low salt diets for restaurant owners and foodservice providers should be seriously considered.

Four different types of silage from new cultivars of Napier grass (Pennisetum purpureum), cv. NG 1 and NG 2, were fed to eight wethers in order to evaluate their preference and intake by sheep. The silages were prepared from direct-cut NG 1 herbage; pre-wilted NG 1 herbage; NG 1 herbage with maize meal (5% inclusion) and NG 2 herbage with maize meal (5% inclusion). All silages were palatable to sheep. Maize-treated silage had high quality fermentation, characterized by high Fleig scores and low pH, volatile fatty acids (VFA) and ammoniacal nitrogen contents. The pH, Fleig score, in vitro digestible organic matter (IVDOMD) and ammoniacal-N contents for maize-treated cv. NG 1 silage were 3.7, 78, $540g\;kg^{-1}$ dry matter (DM ) and $0.18g\;kg^{-1}$ DM whereas, in maize-treated cv. NG 2 they were 3.6, 59, $^458g\;kg{-1}$ DM and $0.18g\;kg^-1$ DM, respectively. The superior quality of maize-treated silages made them more preferable to sheep. Among the maize-fortified silages, palatability and intake were significantly (p<0.001) greater with cv. NG 1. Although direct-cut silage had better fermentation quality compared to wilted silage, wilted silage was significantly (p<0.001) more preferable to sheep. However, there were no significant differences (p<0.05) in the levels of preference and intake of wilted silage compared to maize-treated cv. NG 2 silage, even though the latter tended to be more palatable. There were indications that high pH (4.6 vs 3.5) and IVDOMD content (476 vs $457g\;kg^{-1}%$ DM) of wilted silage contributed to higher intake, compared to direct-cut silage. It was generally concluded that pre-wilting and treatment of Napier grass with maize meal at ensiling enhances intake and palatability.

Selenium (Se) apparent absorption and retention in sheep as influenced by diets differing in protein content through soybean meal supplementation was studied. A $3{\times}3$ Latin square design was used with three Japanese Corriedale wethers (45 kg average body weight), three periods, and three dietary treatments. In each period, 7 d dietary adjustment was followed by 5 d total collection of urine and feces. The three dietary treatments were : Diet 1, without soybean meal supplementation (14% crude protein, CP); Diet 2, with 10% soybean meal supplementation (16.5% CP); and Diet 3, with 20% soybean meal supplementation (19% CP). All the diets had a Se supplementation in the form of sodium selenite at 0.2 mg Se/kg dietary DM. The dietary DM intake of the animals was 2% of their body weight. No significant differences were obtained among the three dietary treatments of the Se balance of the animals. However, as percent of Se intake, only urinary Se concentration of Diet 3 was markedly lower (p < 0.05) than the other diets. Fecal Se as percent of Se intake followed the trend of Diet 3> Diet 2 > Diet 1 resulting a Se absorbed as percent of Se intake of 58.9%, 62.3% and 68.2% for Diets 3, 2 and 1, respectively but their differences among each other were insignificant. No significant differences that were observed either on Se retained as percent of intake (Diet 1, 48.2%; Diet 2, 45.2%; Diet 3, 46.0%) or Se retained as percent of Se absorbed (Diet 1, 70.7%; Diet 2, 72.4%; Diet 3, 77.9%). Significant correlation coefficients among the various measures of Se utilization were also observed. Regression analysis showed the following equation: Y = 93.8 - 1.86X (p <0.05, $r^{2}=0.48$), where Y is the Se absorbed as percent of Se intake (%) and X is the dietary protein content (%). This study concludes that Se requirement in sheep is greater when dietary protein content is high.

The purpose of this study is to investigate the effect of 20s university student bodybuilders' protein intake differences with resistant exercise(weight training) by 12 weeks on solt lean mass and body composltion. Natural protein(Chicken breast meat) intake group and Whey protein isolates(WPI) intake group are the experimental groups. Conventional meal intake group is the control group. This study proposes a efficient protein diet for weight training. The results were as follows. In the experimental group(natural protein intake), muscle mass and lean body mass was significantly increased, but body fat percentage was significantly decreased. In the experimental group(WPI intake), muscle mass and lean body mass was significantly increased, but body fat percentage was significantly decreased. In the control group(conventional meal intake), muscle mass and lean body mass was insignificantly increased, but body fat percentage was insignificantly decreased. In addition, there was not a significant difference among intake groups, and also not a differentiated effect between natural protein and WPI intake. In conclusion, natural protein and WPI made muscle mass and lean body mass rise, body fat percentage reduced effectively. Only WPI intake(without natural protein intake) was the efficient mean to increase muscle mass and lean body mass, and to decrease body fat percentage.
