BACKGROUND/OBJECTIVES: There are limited studies investigating the eating patterns of children's favorite foods. The present study aimed to evaluate a wide range of children's favorite foods, derive its eating patterns, and identify factors related to the patterns. SUBJECTS/METHODS: A nationwide cross-sectional study included 5,458 students in elementary, middle, and high schools. The survey was conducted at each school to evaluate children's favorite food intake, including the intake frequency of 31 food items or food groups, and its related factors, such as demographic, economic, and environmental characteristics and awareness of policies on children's favorite foods. Factor analysis using varimax rotation method and logistic regression analysis were conducted. RESULTS: Two factors were derived as major eating patterns from data of children's favorite foods: the 'unhealthy eating pattern' which mainly involves confectionery, chocolate, ramen, fried food, etc.; and the 'healthy eating pattern' which mainly involves soybean milk, vegetables, fruit juice, and nuts. A stepwise selection procedure through the regression analysis revealed that allowance, use of screen media, less awareness of policies on children's favorite foods, and less interest in health were positively related to the tendency of unhealthy or less-healthy eating patterns (P < 0.05). CONCLUSIONS: This study examined that the eating patterns of children's favorite foods were associated with certain environmental characteristics and awareness about the related policies. These findings suggest that a nutrition education program regarding children's favorite foods needs to be conducted according to the characteristics of students to develop their healthy eating habits and proper choice of favorite foods.

This study examined the basic information on the native pear c.v. 'Baekwoon' grown in Mt. Baekwoonsan, Gwangyang, to develop as a local specialty product. the sensory characteristics, chemical compositions, and physiological activities of 'Baekwoon' pear were examined and compared with those of 'Niitaka' pear. Hardness of 'Baekwoon' pear was 19.30N, which was higher than 'Niitaka'. The sugar content of 'Baekwoon' was 11.5 $^{\circ}Brix$, which was lower than 'Niitaka'. The total amino acid contents of the fruit skin and flesh of 'Baekwoon' were 222 mg/100g dry weight (DW) and 130 mg/100g DW, respectively, which were much higher than those of 'Niitaka'. Especially, serine contents in fruit skin and flesh of 'Baekwoon' were 75.4 mg/100g DW and 40.2 mg/100g DW, respectively, which were significantly (p<0.05) higher than those of 'Niitaka'. However, physiological activities, such as total phenol content, DPPH radical scavenging activity, total flavonoid content and nitrite scavenging activity, of 'Baekwoon' were lower than or similar to those of 'Niitaka'. Consequently, vitamin and amino acid contents of 'Baekwoon' were better than those of 'Niitaka'. It is suggested to use fruit skin because of its good composition and physiological activities so that it helps to improve the quality and the biological activity.

purpose : The purpose of this paper is to report that the fasting treatment was quick and effective against the menopausal depression. So that the further study on the fasting treatment for the menopausal depression is expected. methods : This fasting treatment included three periods. The first was to reduce the food intake and the sodium intake as well. The second was for fasting for two weeks. During this period, the patient drank 250cc of the fermented herbal juice and 2500cc of water a day and had the lactobacillus supplement twice a day. Then, the third was for rebuilding. During the rebuilding period, the patient followed the limited sodium diet for two weeks. results : After the fasting treatment done, the symptoms that patient complained before went away. The BDI score went down from 19 to 3. And, of course, the patient lost her body weight and the fat. conclusions : The 49-year-old female patient in the menopause period was suffering from the lack of energy, depression, sleeping disorder, constipation, and weight gain. She took the fasting treatment along with the acupuncture at the holistic medical clinic, 'The Seasons' from Jan 16th 2009 to Feb 27th(the main fasting period was for 14 days). The BDI score indicated that she had the depression as her score was 19 at the first examination. After the treatment was completed, the BDI score dropped to 3. Therefore, I report the immediate effect of the fasting treatment again the depression. Women are twice as likely to get the depression as men. Especially, the women in menopause period tend to get the depression as they are facing the physical, mental, and social changes which can act as the stressors. Besides, women tend to get depressed when they gain weights. Thus, I suggest the further study on the fasting treatment should be carried on so to apply it more positively to various problems in the field of the psychiatry.

Objective: Spent ginger is a byproduct of juice extraction from the rhizome of ginger (Zingiber officinale). Despite its nutritional value, it is difficult to preserve or further process and thus is often wasted. This study uses spent ginger as a substrate for fermentation and cultivates spent ginger yeast cultures (SGYCs) that are then added to the feed of laying hens. The effects of SGYCs on production performance, egg quality, serum composition, and intestinal microbiota of laying hens were investigated. Methods: Eighty 60-week-old Hy-Line Brown hens were separated into 5 experimental groups with 4 replicates per group (4 hens per cage, 4 cages per replicate). The control group was fed a basal diet while experimental groups were also given SGYCs at the levels of 5, 10, 20, and 40 g/kg for 6 weeks. Results: The addition of SGYCs significantly increased the laying rate and nutrient digestibility, decreased feed conversion ratio, and enhanced the color of egg yolks (p<0.05). No changes were observed in activity levels of alanine aminotransferase and aspartate aminotransferase in the serum (p>0.05), but the activities of superoxide dismutase, glutathione peroxidase, and peroxidase all significantly increased, and contents of malondialdehyde were significantly reduced (p<0.05). In addition, changes in the relative abundance of Firmicutes and Bacteroidetes might be the main factor contributing to the significant increase in the apparent digestibility of crude protein and crude fat in laying hens (p<0.05). Conclusion: The current evidence shows that dietary supplementation of SGYCs to the feed of laying hens can improve laying rates, enhance antioxidative defenses, and influence dominant intestinal bacteria.

This study aimed to compare the dietary habits, nutritional knowledge, and health-related behaviors of students by high school type using questionnaires. The subjects were 586 male students (academic high school students (AS); 294, specialized high school students (SS); 292) in Jinju, Gyeongnam. The frequencies of eating breakfast and snacks were higher in AS than in SS (p<0.05), whereas the frequency of drinking was higher in SS than in AS (p<0.05). The main reason for skipping breakfast was 'poor appetite' in AS (45.2%) and 'lack of time' in SS (56.5%) (p<0.05). Favorite snacks included 'pizza, hamburger' (33.0%) and 'bread, noddle, ramyun' (31.0%) in AS as well as 'pizza, hamburger' (32.5%) and 'fruit, fruit juice' (26.0%) in SS. A mean of 56.2% of students ate an unbalanced diet, and the main reason was 'untasty' (47.2%). The frequency of eating out was higher in SS than in AS (p<0.05), and the main menu while eating out was 'Korean food' in AS (96.3%) and SS (90.3%). The frequency of 'meat, fish, egg, beans' was higher in AS than in SS (p<0.05). On the other hand, the frequencies of 'fruit, fruit juices' (p<0.05), 'milk, milk products' (p<0.01), 'seaweeds' (p<0.05), 'instant foods' (p<0.001) and 'soda and ion drinks' (p<0.001) were higher in SS than in AS. The mean rates of drinking and smoking in students were 84% and 29.5%, respectively. The main reason for drinking and smoking was 'to relieve stress' in AS (38.0%) and SS (30.9%) (p< 0.001). In general, the nutritional knowledge level of SS was higher than that of AS. In conclusion, there were significant differences in the frequencies of eating breakfast, food intake, drinking and reasons for eating snacks, unbalanced diet, drinking and smoking between AS and SS. Therefore, it's necessary to provide proper nutritional education for students according to high school type.

Pumpkin juice (PJ), corn silk tea (CT), and adzuki bean tea (AT) have long been used for treatment of obesity in Korea. This study investigated the efficacy of PJ, CT, AT, and their mixture (PCA) on alteration of body weight and antioxidant metabolism in high-fat diet (HFD)-induced obese rats. After being fed HFD for 4 weeks, SD rats were divided into six groups fed a normal diet (ND), HFD, HFD+PJ [250 mg/kg body weight (BW)], HFD+CT (250 mg/kg BW), HFD+AT (250 mg/kg BW), and HFD+PCA (PJ : CT : AT=1:1:1, 250 mg/kg BW) for another 9 weeks. HFD consumption resulted in total lipid, triglyceride, and total cholesterol accumulation in adipose tissue, which was reduced by administration of PJ, CT, AT, or PCA. The plasma oxygen radical absorbance capacity value and hepatic glutathione peroxidase activity significantly increased compared to the HFD group. The liver thiobarbituric acid reactive substances was significantly lower in the PCA group than the HFD group. HFD-induced DNA damage in hepatocytes, as measured by comet assay, decreased in the PJ, AT, and PCA-supplemented groups. The PCA group exerted a superior antigenotoxic effect compared to other treatments. PCA recovered the concentration of plasma adiponectin, which was reduced by HFD. Adipocyte surface area (%) was significantly higher in the HFD group than the ND group, significantly lower in the PJ and PCA groups than the HFD group, and not significantly different compared with the ND group. Based on the results, supplementation of PJ, CT, AT, and PCA exhibited lipid-lowering effects in adipocytes of HFD-induced obese rats. Furthermore, the PCA group exhibited superior antioxidant activity in all treated groups. This study suggests that a mixed beverage consisting of PJ, CT, and AT may be a significant source of natural antioxidants, which might be helpful in preventing obesity and progress of various oxidative stresses induced by HFD.

Purpose : Iron deficiency anemia (IDA) is one of the most common nutritional deficiencies in children on a weaning diet. We investigated weaning practices in infants and children, as well as their mothers' knowledge about weaning. Methods : We investigated 129 children with IDA and 166 without IDA (aged 6-36 months) who had visited 10 university hospitals between March 2006 and July 2007. We investigated the hematologic values of both groups. A questionnaire on weaning was answered by the mothers of these children. Results : The hematologic values in the IDA group showed a significant difference from those in the comparison group (P<0.05). Children who were solely breastfed until 6 months of age were 85%, 34% (P<0.05), and weaning was started by 6.3, 6.4 months, respectively (P>0.05). Rice gruel, boiled rice, and fruit juice accounted for approximately 80% of the starting foods in both groups (P>0.05). Only 40% of the children in the IDA group had a balanced diet within a month, versus 38% in the comparison group. In response to questions about the necessity of iron-fortified foods for breast-fed infants, less than 50% of mothers in both groups answered correctly. In the IDA group, 42% showed serum ferritin less than 10 ng/mL, while 92% showed serum MCV less than 72 fL. Conclusion : In conclusion, collection of information on history should be thorough for feeding and selective examinations for IDA in high-risk groups. Considering the adaptation period, we suggest beginning children on a weaning diet at 45 months. In addition, we need to educate mothers on weaning practice, especially on the necessity of iron-fortified foods for breast-fed infants.

The purpose of this study was to investigate the night eating habits of middle schoolers. A total of 705 middle school students residing in Gyeonggi were surveyed about their dietary habits related to night eating. Among the total subjects, 59.9% (n=422) had night eating more than once a week and were classified into a night eating group (NEG). The main reason for night eating was hunger (79.1% of NEG) and the highest proportion of night eating was related to food purchased by family (39.3% of NEG). Most of the NEG had night eating in their home with family members, and the time with highest frequency of night eating was between 10 p.m. and 11 p.m.. About 33% of the NEG went to bed within an hour after night eating and 69.2% of the NEG did not report any change after night eating. The most common factors considered when choosing a night eating menu, in order of frequency, were taste, hygiene, and amount. The favorite items on the night eating menu were frozen desserts, fresh fruits, chicken, fruit juice, Ramen, pizza, and Jajangmyeon. The most frequent menu choices were fresh fruits, frozen desserts, Ramen, chicken, yogurt, and fruit juice. The NEG had higher scores for picky eating (P<0.01), overeating (P<0.01), salty eating (P<0.01), and irregular meal times (P<0.001) compared to the non-NEG. Consequently, the NEG had more dietary problems than the non-NEG and their night eating behaviors were related to family habits. Night eating was mainly dominated by a diet of carbohydrates and fats, and the intake frequency and preference for foods with low nutritional value were high; thus, a practical and systematical nutrition education is required. Seasonal and comparative studies on night eating status according to various times and amounts of night eating are also required.

The effects of acetic acid fermented juice prepared with submerged culture media of Antrodia camphorata mycelium (AJA: pH 3.2, acidity 2.0, Brix degree 3.2) on blood glucose levels and serum lipid profiles of rats in which diabetes was induced with streptozotocin (STZ) were investigated. Rats were divided into normal controls (NC), diabetic controls (DM), and groups receiving diluted (1:1, with water) AJA (A1) and undiluted AJA (A2). The volume of liquid given to both A1 and A2 animals was 0.5 mL/100 g body weight. In the A1 and A2 groups, compared with the DM group, polyphagia, liver enlargement, and weight loss caused by diabetes were considerably alleviated, but did not attain the levels of NC group rats. In the A1 and A2 groups, the levels of blood glucose were 17.1% and 28.2% lower than in the DM group. There was no significant difference in the levels of fructosamine between the DM and A1 group, but the A2 group had a level 16.3% lower than the DM group. In the A1 and A2 groups, compared with the DM group, serum triglyceride levels decreased by 44.1-48.0%, serum total cholesterol by 24.0-31.1%, and serum LDL-cholesterol by 25.2-51.1%. The level of HDL-cholesterol in A2 animals rose by 45.9% compared to NC rats. The results show that AJA may be a useful beverage for diabetes patients, offering both antihyperglycemic activity and improvement in levels of serum lipids.

Mao seed is a by-product of the wine and juice industry, which could be used in animal nutrition. The current study was designed to determine the effect of supplementation of mao (Antidesma thwaitesianum Muell. Arg.) seed meal (MOSM) containing condensed tannins (CT) on rumen fermentation, nitrogen (N) utilization and microbial protein synthesis in goats. Four crossbred (Thai Native${\times}$Anglo Nubian) goats with initial body weight (BW) $20{\pm}2kg$ were randomly assigned to a $4{\times}4$ Latin square design. The four dietary treatments were MOSM supplementation at 0%, 0.8%, 1.6%, and 2.4% of total dry matter (DM) intake, respectively. During the experimental periods, all goats were fed a diet containing roughage to concentrate ratio of 60:40 at 3.0% BW/d and pangola grass hay was used as a roughage source. Results showed that supplementation with MOSM did not affect feed intake, nutrient intakes and apparent nutrient digestibility (p>0.05). In addition, ruminal pH and ammonia nitrogen ($NH_3$-N) were not influenced by MOSM supplementation, whilst blood urea nitrogen was decreased quadraticly (p<0.05) in goats supplemented with MOSM at 2.4% of total DM intake. Propionate was increased linearly with MOSM supplementation, whereas acetate and butyrate were remained the same. Moreover, estimated ruminal methane ($CH_4$) was decreased linearly (p<0.05) when goats were fed with MOSM at 1.6% and 2.4% of total DM intake. Numbers of bacteria and protozoa were similar among treatments (p>0.05). There were linear decreases in urinary N (p<0.01) and total N excretion (p<0.01) by MOSM supplementation. Furthermore, N retention was increased linearly (p<0.05) when goats were fed with MOSM supplementation at 1.6% and 2.4% of total DM intake. Microbial protein synthesis were not significantly different among treatments (p>0.05). From the current study, it can be concluded that supplementation of MOSM at 1.6% to 2.4% of total DM intake can be used to modify ruminal fermentation, especially propionate and N utilization in goats, without affecting the nutrient digestibility, microbial populations and microbial protein synthesis.
