BACKGROUND/OBJECTIVES: This cross-sectional study assessed household food security status and determined its association with diet quality and weight status among indigenous women from the Mah Meri tribe in Peninsular Malaysia. SUBJECTS/METHODS: The Radimer/Cornell Hunger and Food Insecurity Instrument and the Malaysian Healthy Eating Index (HEI) were used to assess household food security status and diet quality, respectively. Information on socio-demographic characteristics and 24-hour dietary recall data were collected through face-to-face interview, and anthropometric measurements including weight, height, and body mass index (BMI) were obtained from 222 women. RESULTS: Majority of households (82.9%) experienced different levels of food insecurity: 29.3% household food insecurity, 23.4% individual food insecurity, and 30.2% fell into the child hunger group. The food-secure group had significantly fewer children and smaller household sizes than the food-insecure groups (P < 0.05). The mean household income, income per capita, and food expenditure significantly decreased as food insecurity worsened (P < 0.001). The food-secure group had significantly higher Malaysian HEI scores for grains and cereals (P < 0.01), as well as for meat, poultry, and eggs (P < 0.001), than the food-insecure groups. The child-hunger group had significantly higher fat (P < 0.05) and sodium (P < 0.001) scores than the food-secure and household food-insecure groups. Compared to the individual food-insecure and child-hunger groups, multivariate analysis of covariance showed that the food-secure group was significantly associated with a higher Malaysian HEI score while the household food-insecure group was significantly associated with a higher BMI after controlling for age (P < 0.025). CONCLUSIONS: The majority of indigenous households faced food insecurity. Food insecurity at the individual and child levels was associated with lower quality of diet, while food insecurity at the household level was associated with higher body weight. Therefore, a substantial effort by all stakeholders is warranted to improve food insecurity among poorer households. The results suggest a pressing need for nutritional interventions to improve dietary intake among low income households.

This study was carried out to evaluate performance and uniformity of White Korean native ducks collected from two areas in Korea. White ducklings were selected from all ducklings that were hatched from hatchery eggs of Korean native ducks. A total of two hundred forty white ducklings (1-d-old) were used in this work and were divided into 4 groups (4 replicates/group, 15 birds/replicate) with $2{\times}2$ factors (2 groups, J, H; genders, male and female). Weekly body weight of H groups was higher than that of J groups (P<0.05). Also, weekly body weight of male ducks was higher compared to that of female at 6~8 wk old (P<0.05). Uniformity of J groups was higher than that of H groups at the age of 1 wks old (P<0.05), and that of female duck was higher than that of male at the age of 6 wks old (P<0.05). Body weight gain of H group was higher than that of J group (P<0.05), and that of male duck was higher compared to that of female at 6~7 wks old (P<0.05). Feed intake of H group was higher compared to that of J group (P<0.05), but there was no significant difference between male and female on feed intake. On feed conversion ratio, J group was higher than H group at 4~5 wks, 7~8 wks and 0~8 wks old (P<0.05), and feed conversion ratio of male duck was higher than that of female at 1~2 wks, 5~6 wks and 6~7 wks old. Finally, these results was tended to show that performance of H groups was higher than that of J groups. Further researches need to carry out to commercial White Korean native ducks on performance and uniformity as well as meat quality and genetic characteristic.

The traditional (European) Mediterranean diet is characterized by an abundance of plant foods such as bread, pasta, vegetables, salad, legumes, fruit, nuts; olive oil as the principal source of fat; low to moderate amounts offish, poultry, dairy products and eggs; only small amounts of red meat; low to moderate amounts of wine, normally consumed with meals. This diet is low in saturated fatty acids, rich in carbohydrate and fibre, and has a high content of monounsaturated fatty acids (MUFA). These are primarily derived from olive oil. Despite a wealth of general knowledge concerning the major classes of compounds present in olives and olive oil, detailed knowledge of the phenolic antioxidant content has been lacking. Therefore the aim of the study was to evaluate the phenolic antioxidant content in a range of olive and seed oils. While seed oils were devoid, on average, the olive oils contained $196{\pm}19mg/kg$ total phenolics as judged by HPLC analysis, but the value for extravirgin ($232{\pm}15 mg/kg$) was significantly higher than that of refined virgin olive oil ($62{\pm}12mg/kg$; P<0.0001). Appreciable quantities of simple phenols (hydroxytyrosol and tyrosol) were detected in olive oils, with significant differences between extravirgin ($41.87{\pm}6.17$) and refined virgin olive oils ($4.72{\pm}2.15$; P<0.01). The major linked phenols were secoiridoids and lignans. Although extravirgin contained higher concentrations of secoiridoids ($27.72{\pm}6.84$) than refined olive oils ($9.30{\pm}3.81$) this difference was not significant. On the other hand the concentration of lignans was significantly higher (P<0.001) in extravirgin ($41.53{\pm}3.93$) compared to refined virgin olive oils ($7.29{\pm}2.56$). All classes of phenolics were shown to be potent antioxidants. In future epidemiolgic studies, both the nature and source of olive oil consumed should be differentiated in ascertaining cancer risk.

Objectives: This study was designed to investigate the relationship between metabolic risk factors, Index of Nutrition Quality, and the dietary quality index score of Korean adults. Methods: The subjects were 18,652 Korean adults aged 19 years or older (7,899 males, 10,753 females) who participated in the 2016-2019 Korea National Health and Nutrition Examination Survey. Subjects were divided into normal, pre-metabolic syndrome, and metabolic syndrome (MetS) groups according to the number of their metabolic risk factors. Data were analyzed using the SPSS program. Results: About 44.7% of men in the MetS group were at least college graduates (P < 0.001), whereas 52.0% of women in the MetS group were middle school graduates or lower (P < 0.001). The frequency of fruit and dairy products intake tended to decrease as the number of metabolic risk factors increased in both men and women (P for trend < 0.001). As the number of metabolic risk factors decreased, the frequency of grain intake tended to decrease in men (P for trend < 0.001) while the frequency of intake of red meat (P for trend = 0.001), poultry (P for trend < 0.001), and eggs (P for trend < 0.001) decreased in women. The total scores of Diet Quality Index-International (DQI-I) (men P < 0.001, women P < 0.01) and Korean Healthy Eating Index (KHEI) (men and women P < 0.001) were significantly lower in the MetS group compared to the other groups, and the total score of DQI-I and KHEI tended to decrease as the number of metabolic risk factors increased. Conclusions: Dietary quality evaluation using various indices can provide more information on the dietary problems related to metabolic risk factors. Nutrients and foods that have been confirmed to be related to metabolic risk factors can be used to develop dietary guidelines for the nutritional management of metabolic diseases.

Nitrate a common component of man's chemical environment, is present in foods either naturally or in an additive introduced during processing of foods. Nitrate level of foods have been found depending on nitrosation of soils and other various environmental factors. Therefore data on nitrate contents of foods reported in other countries can not be adapted to Korean foods. Also data on nitrate levels of Korean foods available were reported 10 years ago, which would be assumed to differ from those of foods currently consuming by Koreans. The present study was attempted to determine nitrate contEnts of common foods. Based on National Nutrition Survey Report 143 food items out of 14 food groups were selected for this study Nitrate levels of common foods used in the study were from N.D (not detected) to 6733.33 mg/kg foods. Mean nitrate levels of food groups 27.2 mg/kg of cereal and grain products, 78.1 mg/kg in potatoes and potato products, 8.3 mg/kg in legumes and their products N.D of seeds and nuts, 1012.1 mg/kg of vegetables and their products,76.3 mg/kg fungi and mushrooms 42.2 mg/kg fruits,34.5 mg/kg of meat, poultry and their products,0 mg/kg in eggs, 23.9 mg/kg in fish, shellfishes and their products,23.0 mg/kg in seaweeds, 7.7 mg/kg milk and dairy products, 26.3 mg/kg in seasonings, 68.0 mg/kg in others.

This study investigated parents' attitude about children's unbalanced diet. The subjects were 1,309 parents that their children attended at kindergarten or child care center in Kyoung-Ki province. The order of dislikes in 'vegetables and fruits' was as follows: all kinds of vegetables (56.6%), beans (17.6%), fruits (5.2%). In 'meat, fish, poultry', the order of dislikes was meats (38.2%), fishes (21.8%), milk (16.4%), eggs (10.0%). In 'cerelas', the order of dislikes was rice (31.0%), rice cakes (14.3%), noodles (11.9%). The several rationalizations for dislikes are 'taste' (19.1 %), 'food habit from younger age' (18.4%), 'lack of chances for trying new food' (16.0%) etc. To compared children's rationalizations for dislikes to their age group, the percentage of 'lack of chances for trying new food', 'strange food shape', 'lack of nutrition education' was significantly higher in 'below 5 years old' (<5) group than other groups (<6, <7) and 'sweety food' was significantly higher in 'below 7 years old' (<7) group than other groups (<6, <7)(p <0.05). In parents' attitude about children's unbalanced dietary habit, subjects answered that they try to make children understand to eat dislike food (73.9%), develop new recipe for children (14.0%), neglect children's food habit (6.2%). To compared parents' attitude for children's unbalanced diet by parents age, the percentage of 'try to make children understand to eat dislike food' was significantly higher in 'below 30 years old' (<30) group than other groups ($30{\sim}35,\;35{\sim}39,\;{\geq}40$) and 'developing new recipe' was significantly higher in 'over 40 years old' (${\geq}40$) group than other groups ($<30,\;30{\sim}35,\;35{\sim}39$)(p < 0.05). To compared parents' attitude for children's unbalanced diet by parents' occupation, the percentage of 'neglecting' was higher in employed group and 'developing new recipe' was higher in unemployed group than the other group. According to the results of the survey, it is necessary to make new educational materials for employed parents and young children and develop new recipes to use various kind of foods instead of forcing unpleasant foods on the children for the sake of unbalanced diet.
