In the past, poultry nutrition has focussed on increasing the production efficiency to meet the progress achieved in the genetic potential of broilers and layers. Future directions in poultry nutrition will be driven by not only by the need to maximise biological and economic performance of birds, but also by societal issues (environment, antibiotic growth promoters, welfare, traceability and use of genetically modified ingredients). Key advances in poultry nutrition are discussed and future directions, which can be expected, are highlighted. Given the tightening supply and ever-increasing cost of raw materials, there will be more pressure to extract every unit of energy and nutrients from feed ingredients. In this context, a number of feed additives are expected to play an increasingly significant role. Feed enzymes and crystalline amino acids, in particular, will have a profound effect on future sustainability of the poultry industry. Future nutritional research need to focus on identifying the barriers to effective digestion and utilisation of nutrients and, to achieve this objective, nutritionists must combine their expertise with those of specialising in other biological sciences, including immunology, microbiology, histology and molecular biology.

BACKGROUND/OBJECTIVE: Even though the prevalence of metabolic syndrome in adolescents is increasing, little is presently known about this syndrome in adolescents. This study aimed to cluster metabolic risk factors as well as examine the associations between identified patterns and nutrient intake using data from the Korean National Health Examination and Nutritional Assessment (KNHANES). SUBJECTS/METHODS: A total of 2,958 subjects aged 10 to 18 years along with both biochemical and dietary data information were obtained from KNHANES 2007-2010. Six components of metabolic syndrome were used to identify any patterns via factor analysis. Individuals were categorized into quartile groups according to their pattern score. RESULTS: Three clustering patterns with high loadings were identified and named as follows: 1) high blood pressure, 2) dyslipidemia, and 3) glucose abnormality patterns. The high blood pressure pattern showed high loadings of systolic and diastolic blood pressures, the dyslipidemia pattern showed high loadings of triglyceride and HDL-cholesterol levels, and the glucose abnormality pattern showed high loadings of fasting blood glucose levels. Intakes of fat and riboflavin were significantly decreased, whereas those of sodium and niacin were significantly increased across the quartiles in the dyslipidemia pattern. No nutrient intake except that of thiamin was significantly associated with the high blood pressure or glucose abnormality pattern. CONCLUSION: Our findings show that metabolic syndrome risk factors in the Korean adolescent population are characterized by three distinct patterns, which are differentially associated with dietary factors. Characterizing metabolic risk factors and providing specific dietary guidelines for target groups are important.

Levels and distribution of five B-6 vitamers(PMP, PM, PLP, PL, and PN) and pyridoxine $\beta$-glucoside conjugates(PN-glucoside) were examined in milk of American women who received supplements of 2.5 or 10mg PN HCl/d and of unsupplemented Egyptian women during the first six months of lactation. B-6 vitamer and PN-glucoside levels in human milk were determined by reverse-phase HPLC. Pyridoxal(PL), which has been reported to be the most rapidly absorbed form of vitamin B-6 and may facilitate bioavailability, was the predominant vitamer in human milk of all three groups. Pyridoxal made up 72% of total vitamin B-6 for the 2.5mg supplemented group, 76% for the 10mg group, and 59% for the Egyptian group. Level and Percent PL were significantly lower for Egyptian women. Mean growth of the two American groups was similar to each other and within the normal range of the NCHS reference, however, Egyptian infants showed growth faltering at 6 months. The Percent of PN-glucoside, a less bioavailable form of vitamin B-6 in humans was 1% in milk of American women and was 11% in Egyptian women and these values were significantly different. for Egyptian women, total vitamin B-6 levels in breast milk correlated Positively with animal protein intake(r=0.91) and percent PN-glucosides(r=0.53) and negatively with plant protein intake(r=-0.55). These findings showed that high plant protein intake was associated with low concentrations of PL and total vitamin B-6 in human milk.

Purpose: Obesity is associated with alterations in vitamin D metabolism and elevation of parathyroid hormone (PTH). Increased PTH level in obesity is likely one of the factors contributing to the dysregulation of vitamin D metabolism. We investigated the effects of lowering the PTH level in high-fat diet-induced obese mice on vitamin D metabolism. Methods: Five-week-old male C57BL/6N mice were fed either with control (10% energy as fat) or high-fat (60% energy as fat) diets ad libitum for 12 weeks, and vehicle or cinacalcet HCl (30 ㎍/g body weight) was gavaged daily during the final week of the experiment. The following groups were studied: CON (control diet + vehicle), HFD (high-fat diet + vehicle), and HFD-CIN (high-fat diet + cinacalcet HCl). PTH, 1,25-dihydroxyvitamin D (1,25[OH]₂D), 25-hydroxyvitamin D (25[OH]D), calcium, and phosphate levels in circulation, and the expression of genes related to vitamin D metabolism in the liver and kidneys were determined. Results: Renal 1α-hydroxylase expression in the HFD group was higher than that in the CON group despite the lack of a difference in the PTH levels between the 2 groups. The plasma PTH level in the HFD-CIN group was 60% lower than that in the HFD group (p < 0.05). In parallel, the HFD-CIN group had lower adipose tissue amount (9% lower), renal 1α-hydroxylase expression (48% lower), and plasma 1,25(OH)₂D concentration (38% lower) than the HFD group. Conclusion: Lowering the PTH levels in high-fat diet-induced obese mice recovered the expression of renal 1α-hydroxylase and might be associated with lower amounts of white adipose tissue.

The purpose of this study is to investigate zinc and copper intakes of exclusively breast-fed infants. We measured consumed volume and the minerals concentrations of human milk from thirty three lactating women and their infants during the first 5 months of lactation , Zinc concentrations of human milk showed 0.394, 0.290, 0.191, 0.147 and 0.139mg/100g at 0.5, 1, 2, 3, 4 and 5 months of lactation respectively. Copper concentrations in the milk showed 61.04, 45.97, 37.15, 3.94, 26.22 and 26.21$\mu\textrm{g}$/100g respectively. Consumed volume of the milk of infants were 515, 650, 718, 731, 746 and 769g/day. There is significant difference between boys and girls in consumed volume of the milk at 2, 3 and 4 months of lactation. Zinc intakes of breast-fed infants declined(p<0.05) from 2.13mg/day at 0.5 months to 1.21mg/day at 3 months with no change thereafter significantly. Copper intakes of the infants declined(p<0.05) from 323.2$\mu\textrm{g}$/day at 0.5 months to 238.9$\mu\textrm{g}$/day at 3 months with no change thereafter. Form this survey, the reevaluation of zinc and copper intakes and recommended dietary allowance of those minerals during infancy are merited. (Korean J Nutrition 33(8) : 857-863, 2000)

This study conducted a secondary analysis by using original data of performed by Korea Institute for Health and Social Affairs to know factors affecting determinants of health using Lalonde model for the adults aged over 19 years living in Korea. The survey was conducted in 2009 and it evaluated finally 5,867 cases by excluding cases with no answer or a wrong answer. This study model adopted two categories of instrument measure health were objective (Average remaining lifetime) and subjective(EQ-5D) health status. The health determinants included in this study could be divided in to four categories, which were human biology, environment, lifestyle, and health care organization. The results were as follows. In the factors affecting average remaining lifetime, human biology were sex, ages, BMI, showed statistically significant difference, environment category were merry status, education showed statistically significant difference, lifestyle category were exercise, drunks showed statistically significant difference and health care organization category were vaccination, health screening showed statistically significant difference. In the factors affecting EQ-5D, human biology category and health care organization category showed with same average remaining lifetime, environment category were merry status, education, income showed statistically significant difference and lifestyle category were exercise, drunks, stress showed statistically significant difference. The results demonstrated that the best powerful factor was life style category and environment category, the least factor was health care organization category. So lifestyle style and environment category should be considered for the future health plan, budget allocation and the priority in the health care.

The purpose of this study was to identify the factors associated with skipping breakfast of Korean children by analyzing the 24-hour recall intake data from the 2001 National Health and Nutrition Survey. The sample of this study consisted of 1,600 children aged 7 to 18 years. About 17% of the children skipped breakfast, consuming no food or beverage at all. About 30% of children reporting breakfast skipping in a self-administered survey were shown to have eaten some foods as a result of analysis of the 24-hour recall data. Students having eaten breakfast consumed 21% of Estimated Energy Requirement at breakfast. The multivariate logistic regression analyses showed that age was associated with skipping breakfast both in elementary and middle/high school students; older students were more likely to skip breakfast. Elementary school students from low-income families were more likely to skip breakfast than those from upper-high income families. Intervention programs are needed to prevent children from skipping breakfast by targeting older students. For elementary school students, such programs should be first developed for those from low-income families.

The purpose of this study was to compare the nutritional status of children aged 5 or under and women aged 20 to 34 years between the Republic of Korea (South Korea) and the Democratic Peoples' Republic of Korea (DPRK: North Korea). For the source of nutritional status of North Koreans, the DPRK 2004 Nutrition Assessment-Report of Survey Results was used. As the comparable data of South Koreans, the anthropometric data for children and women were obtained from the reports of the Korean Pediatric Society and the Korean Agency for Technology and Standards, respectively. The blood hemoglobin data of South Korean women were obtained from the data file of the 2001 National Health and Nutrition Survey and analyzed. In regard to the North Korea, the Prevalence of underweight (weight for age Z-score < -2.0) in children under 12 months was about $10\sim15%$, and thereafter progressively increased until 30 to 35 months reaching 30%. In South Korea, the prevalence of underweight was less than 3% in most age groups both in boys and girls. In North Korea, the prevalence of stunting (height for age Z-score < -2.0) reached 20% in children under 12 months and increased with age over the level of 50% in children aged 54 to 59 months. In South Korea, the prevalence of stunting was less than 3% in children under 12 months and was less than 10% throughout the age groups. Maternal protein-energy malnutrition and anemia were assessed for the women aged 20 to 34 years using mid-upper arm circumference (< 22.5 cm) and blood hemoglobin level (< 12g/DL), respectively. The prevalence of protein-energy malnutrition was 39.6%, 30.7%, 31.7% in North Korea and 12.5%, 5.0%, 1.5% in South Korea fir the women in $20\sim24,\;25\sim29,\;30\sim34$ years, respectively. The prevalence of anemia in the North Korean women was about $34\sim36%$ while that in the South Korean women was $15\sim18%$. In conclusion, the disparity of nutritional status in early childhood and maternity between South Korea and North Korea is so huge that active and well-planned nutrition support policy and programs for women and children in North Korea is imperative to prepare for the future unified nation.
