The aim of the present study was to assess the effects of skipping breakfast on diet quality and metabolic disease risk factors in healthy Korean adults. Subjects included 415 employees (118 men, 297 women; 30-50 years old) of Jaesang Hospital in Korea and their acquaintances. Data collected from each subject included anthropometric measurements, 3-day dietary intake, blood pressure, and blood analyses. The subjects were classified into three groups based on the number of days they skipped breakfast: 'Regular breakfast eater', 'Often breakfast eater', or 'Rare breakfast eater'. Participants in the 'Rare breakfast eater' group consumed less rice, potatoes, kimchi, vegetables, fish and shellfish, milk and dairy products, and sweets than did participants in the other two groups (P for trend <0.05) and ate more cookies, cakes, and meat for dinner (P for trend <0.05). Participants in the 'Rare breakfast eater' group consumed less daily energy, fat, dietary fiber, calcium, and potassium than did participants in the other groups (P for trend <0.05). The percent energy from carbohydrates was lower and fat intake was higher in the 'Rare breakfast eater' group than in the other groups (P for trend <0.01). When diets were compared using the Acceptable Macronutrient Distribution Range for Koreans, 59.1% of subjects in the 'Rare breakfast eater' group consumed more energy from fat compared with the other two groups (P <0.005). According to the Estimated Average Requirements for Koreans, intake of selected nutrients was lower in the 'Rare breakfast eater' group than in the other two groups (P <0.05). The risk of elevated serum triglycerides was decreased in the 'Rare breakfast eater' group (OR, 0.3 [0.1-1.0], P for trend=0.0232). We conclude that eating breakfast regularly enhances diet quality, but may increase the risk of elevated serum triglycerides.

Histamine has been known to be one of the causative materials of allergy-like food poisoning from eating of the meat of the dark-fleshed fishes. In the previous study, we had reported the changes of histamine contents fin three kinds of the dark-fleshed fishes. The present paper was also conducted to investigate the changes of the histamine contents in the mackerel pike, and compare with the white-fleshed fish, spanish mackerel, under different condition of storage and processing. The formation of histamine in the muscle of mackerel pike was markedly higher than spanish mackerel. Referring to temperature, the formation of histamine at $12^{\circ}C$ was observed more rapid than that at $2^{\circ}C$. In the muscle of mackerel pike, the histamine contents reached the levels of 98.3mg/100g for at the storage for 5 days at $12^{\circ}C$. But in that of spanish mackerel, the content showed the level of 4.9mg/100g at the storage 7 days at $12^{\circ}C$. The histamine contents in sun dried products of the samples were higher than those of rat-materials, salted or hot-air dried products.

The purpose of this study is to analyze the differences of food habits and food preferences between lower and higher grade students through the survey of elementary school students in Daejeon four elementary schools located in Jung-Gu and Seo-Gu in Daejeon are selected for this survey randomly and the completion of the questionnaires are according to grade. 1. Practical Analysis of Food Habits: For regular meals, the highest number of subjects skipped breakfast. It is being found that the girl students (81.61%) consumed more cooked rice than the boys (78.85%) and more boys (13.10%) ate bread or milk more than the girls (9.20%). The most important thing for the lower grades students (34.20%) when consuming is the nutritious foods, while the higher grades students (49.67%) consumed the set meals. During consumption, the highest number of the subjects watched TV or read books from time to time. More higher grades students (38.98%) preferred spicy and salty foods than the lower grades (22.09%). 2. Food Preferences: Between rice and noodles, most subjects preferred cooked rice (81.38%), Jajangmyeon (80.80%), Ramyeon (79.43%), and disliked bean-mixed rice (28.39%). For soups, Most students enjoy the Deokkguk. Majority of the subjects prefer meat and fried or steamed foods, and also grilled and pan-fried dishes. For the pan-roasted and fried dishes, most subjects did not enjoy the rhizome fry and sweet-pumpkin fry methods, and for vegetables, they did not like wild vegetable and seasoned cucumber (40.57%) The higher grades students enjoy the vegetables and salads more than the lower grades students. For Kimchi varieties, it is found that subjects like the cabbage Kimchi (69.66%) the most. There is little difference in food preference between the lower and higher grade students, but the rankings of food preferences are different according to various grades.

Purpose: The aims of this case-control study were to assess the correlation between some food habits in the last two decades and gastric cancer in East Azerbaijan of Iran. Materials and Methods: In this hospital based case control study, 616 patients (212 gastric cancer patients, 404 cancer free patients) were recruited. Food habits of patients over the past two decades were assessed with a structured questionnaire. We used conditional logistic regression analysis for estimating crude and adjusted odds ratios (OR) and their respective 95% confidence intervals (95%CI). Results: In this study, over-eating, consumption of high fat milk and yogurt and especial types of cheese increased the risk of gastric cancer (All<0.05). Consumption of such especial cheeses such as Koze and Khiki increased the risk of gastric cancer by 12.6 fold (95% CI:1.99-79.36) and 7.36 fold (95% CI:1.33-40.54), respectively. In addition, high fat food, moldy food, and pickled vegetables consumption as well as reuse of cooking oil for frying were significantly associated with gastric cancer risk. Furthermore, intake of Ghorme (deep fried meat) was positively correlated with gastric cancer risk (OR:1.31;95%CI: 0.91-1.87). Conclusions: It can be confirmed that particular food habits which have been very common in East-Azerbaijan in the last two past decades increase risk of gastric cancer. According to our results and taking into account the long latency period of gastric cancer it can be concluded that nutrition education for a healthy diet should be performed from early childhood. However, further well designed cohort studies are needed to achieve more clear results.

A study was conducted to evaluate nutritional value for twenty-one pork muscles. Ten market-weight crossbred pigs (five gilts and five barrows) were used for evaluating proximate chemical composition, cholesterol, total iron, calorie and fatty acid contents. As preliminary analysis revealed no noticeable sex effect, pooled data from both sexes were used for the final analysis. M. rectus femoris had the highest moisture content, while m. latissimus dorsi was lowest in moisture content (p<0.05). Protein content was highest for m. longissimus dorsi and lowest for m. supraspinatus (p<0.05). The tensor fasciae and latissimus dorsi muscles contained the highest intramuscular fat (p<0.05), while rectus femoris, adductor and vastus lateralis were lowest in intramuscular fat content. When simple correlations between chemical values were computed for the pooled dataset from all muscles, intramuscular fat had significant (p<0.05) negative linear relationships with moisture (r = -0.85) and protein (r = -0.51) contents. Calorie levels were not significantly affected by fat content, while rectus femoris and latissimus dorsi muscles showed lowest and highest calorie contents, respectively (p<0.05). Polyunsaturated fatty acid content was highest (p<0.05) for both m. adductor and m. rectus femoris, while it was lowest for m. longissimus dorsi. Collectively, the current study identified a large amount of variation in nutritional characteristics between pork muscles, and the data can be used for the development of muscle-specific strategies to improve eating quality of meats and meat products.

BACKGROUND/OBJECTIVES: Diet plays an important role in growth and development of children. However, dietary intakes of children living in either rural or urban areas can be influenced by household income. This cross-sectional study examined energy, nutrient and food group intakes of 749 urban children (1-10 years old) by household income status. SUBJECTS/METHODS: Children's dietary intakes were obtained using food recall and record for two days. Diet adequacy was assessed based on recommended intakes of energy and nutrients and food group servings. RESULTS: For toddlers, all nutrients except dietary fiber (5.5 g) exceeded recommended intakes. Among older children (preschoolers and school children), calcium (548 mg, 435 mg) and dietary fiber (7.4 g, 9.4 g) did not meet recommendations while percentage of energy from total fat and saturated fats exceeded 30% and 10%, respectively. The mean sodium intakes of preschoolers (1,684 mg) and school children (2,000 mg) were relatively high. Toddlers in all income groups had similar energy and nutrient intakes and percentages meeting the recommended intakes. However, low income older children had lowest intakes of energy (P < 0.05) and most nutrients (P < 0.05) and highest proportions that did not meet recommended energy and nutrient intakes. For all food groups, except milk and dairy products, all age groups had mean intakes below the recommended servings. Compared to middle and high income groups, low income preschoolers had the lowest mean intake of fruits (0.07 serving), meat/poultry (0.78 serving) and milk/dairy products (1.14 serving) while low income toddlers and school children had the least mean intake of fruits (0.09 serving) and milk/dairy products (0.54 serving), respectively. CONCLUSION: Low socioeconomic status, as indicated by low household income, could limit access to adequate diets, particularly for older children. Parents and caregivers may need dietary guidance to ensure adequate quantity and quality of home food supply and foster healthy eating habits in children.

Food neophobia, unwillingness to try novel foods, is a personality trait that can influence children's food preferences and consequently their food acceptance and consumption. The purpose of this study was to determine whether children with food neophobia have poor dietary and growth outcomes compared to non-neophobic children. Subjects were 332 primary school children from 6 randomly selected schools in the district of Hulu Selangor, Selangor. Parents and children were interviewed to obtain demographic, socio-economic, food neophobia and dietary intake information. The children were also measured for weights and heights. One-way ANOVA and Chi-square procedures were utilized for statistical data analysis. Children with food neophobia had higher intakes of energy and most nutrients than average and neophilic children. However, only the mean intakes of protein (p < 0.05) , fat (p < 0.05), vitamin A (p < 0.01) and iron (p < 0.01) were significantly higher in neophobic than average or neophilic children. Compared to neophilic and average groups, a higher percentage of neophobic children met 2/3 of the RNIs for energy $(85.2\%)$, protein $(98.4\%)$ and vitamin A $(72.1\%)$. Mean percentage of carbohydrate energy was lowest$(54.8\pm6.6\%)$ while fat energy $(31.8\pm6.2\%)$ was highest among neophobic children. Neophobic group had the lowest percentage of children $(49.2\%)$ with carbohydrate energy > $55\%$ but highest percentage $(50.8\%)$ with fat energy > $30\%$. For the three study groups, the mean number of servings for all food groups, except grain and cereal, did not meet the Food Pyramid recommendations. Neophobic children consumed significantly more numbers of servings from the meat group than average and neophilic groups (p < 0.01). All study groups had relatively low mean dietary diversity scores but neophobic children had the lowest score $(0.67\pm0.73)$ compared to the average $(0.97\pm0.72)$ and neophilic $(1.98\pm0.81)$ groups. Significant difference in mean dietary diversity scores were only observed between neophobic and neophilic children (p<0.05). Higher percentages of neo-phobic children had low weight-for-height and were at-risk of overweight(p < 0.05). Nutrition practitioners need to understand children's food preferences in their efforts to promote healthful diets for children. To improve children's eating behaviors, parents may need the guidance and support from nutritionists and dietitians that are specific to their needs and their child's situation.

Objectives: An association between dietary patterns and mental health in children has been suggested in a series of studies, yet detailed analyses of dietary patterns and their effects on ADHD (attention deficit hyperactivity disorder) are limited. Methods: We included 4569 children who had dietary intake data as part of the CHEER (Children's Health and Environmental Research) study conducted nationwide from 2005 to 2010. We assessed ADHD (Attention Deficit Hyperactivity Disorder) by the DuPaul's ADHD Rating Scales and dietary intake by a semi-quantitative food frequency questionnaire. Using intake data, we constructed five dietary patterns: "Plant foods & fish," "Sweets," "Meat & fish," "Fruits & dairy products," and "Wheat based." Results: The overall proportion of ADHD was 12.3%. Boys (17.8%) showed a higher rate of ADHD than girls (6.5%). The total intake of calories (85 kcal) and plant fat (2g) in the ADHD group was significantly higher than that of the normal group. ADHD was significantly negatively associated with dietary habits such as having breakfast and meal frequency, and positively associated with eating speed, unbalanced diet, overeating, and rice consumption. Regarding dietary patterns, the "Sweets" category was relevant to high ADHD risk (OR 1.59, 95% CI: 1.18, 2.15 for Q5 vs. Q1) in a linear relationship. An inverse, non-linear association was found between "Fruits & dairy products" and ADHD (OR 0.55, 95% CI: 0.39, 0.76 for Q4 vs. Q1). Conclusions: Our study confirms both positive and negative associations between diet and ADHD in elementary school age children. Moreover, linear or nonlinear associations between diet and ADHD draw attention to the possible threshold role of nutrients. Further studies may consider characteristics of diet in more detail to develop better intervention or management in terms of diet and health.

The aim of the present study was to evaluate the variation in ultimate pH of commercial populations of pure-breed (Landrace, Duroc and Yorkshire) pig's longissimus muscles and their effect on objective meat quality traits and sensory characteristics. Fifty boars were sampled from 184 pigs, which were reared at three breeding farms and slaughtered at a commercial abattoir. The selection was determined based on ultimate pH, and animals were segregated into three groups: low pH (pH $\leq$ 5.5, n=13), medium pH (pH 5.5 to 5.6, n=18) and high pH (pH $\geq$ 5.6, n=16). The breeds had no significant effects; however, pigs with a higher ultimate pH had significantly (p<0.05) higher intramuscular fat content, lower level of polyunsaturated fatty acids, lower level of lipid oxidation and higher eating quality compared to those with lower ultimate pH. As the ultimate pH increased, the relative proportion of C14:0, C16:0 and C18:1 increased while C18:2n6 and C20:4n6 decreased. The present study demonstrates that the economic value of pigs can be characterized by the ultimate pH and/or intramuscular fat content. However, these results do not necessarily indicate that a high ultimate pH directly corresponds to high intramuscular fat content and vice versa.
