Nutrition is an essential component of total adolescent health care. Two important changes occurring during adolescence can cause a crisis in the teenager's nutritional needs. First, growth in height, weight, and body component is greater and more rapid than at any time since infancy. Second, an adolescent's eating habits may change from regular meals prepared at home to irregular meals, skipped meals, and nutrition-poor snacks and fast-food meals. Adolescents have been found to have the highest prevalence of any age group of an unsatisfactory nutritional status. To understand the nutritional requirements of the adolescent, health practitioners should be aware of the intensity and timing of the adolescent growth spurt, the differences in the growth spurt between males and females, and the individual variation in timing of the growth spurt from teenager to teenager.

Tumor invasion is composed of four steps: cell adhesion to the extracellular matrix, degradation of the extracellular matrix components, tumor cell motility followed by cell detachment. Matrix metalloproteinases (MMPs) are important proteinases that associated with degradation of matrix component. Epigallocatechin gallate (EGCG) is a major polyphenotic constituent of green tea. In the study, we examined the anti-invasive and MMP activity suppression effects of EGCG in MDA-MB-231 human breast cancer cells. MDA-MB-23l human breast cancer cells were cultured with various concentrations 0 - 100 μM of EGCG. EGCG significantly inhibited the cell adhesion to the fibronectin. Cell motility through gelatin filter and invasion to Matrigel were inhibited dose-dependently by EGCG treatment. EGCG also inhibited the activities of MMP-2, -9 and the amount of MMP-9 (α = 0.05). Therefore, EGCG may contribute to the potential beneficial food component to prevent the invasion and metastasis in breast cancer. (Korean J Nutrition 38(2): 104～111, 2005)

Component analysis and physico-chemical properties of wood and rice hull vinegars were conducted in order to promote the utilization of these environment-friendly materials. Results showed that wood vinegar had higher specific gravity (2.5) and tar content (0.3%), but lower acid content (1.0%) than rice hull vinegar (1.7, 0.05% and 4.4%, respectively). GC-MS component analysis revealed that rice vinegar had higher phenol content (34%) than wood vinegar (11.49%). Acetic acid and propionic acid were also higher in rice hull vinegar. On the contrary, wood vinegar had higher Furancarboxyl aldehyde content (41.6%) than rice hull vinegar (0.67%). Thus, different results in DPPH radical electron donating-abilities were obtained due to different percent composition of each vinegar.

This retrospective study was designed to evaluate the nutrient contributions of the five meal components of school lunch menus planned for elementary students in two school districts (District A and B) in the Midwestern state of the United States. The 4-week cycle menu was planned for two time periods (Period 1 and Period 2) following guidelines for NuMenus and general menu planning principles. Menu components of planned and served menus for two time periods were analyzed using $Nutri-Kids^{TM}$. No significant differences in the nutrient content of between Periods 1 and 2 were found for District A. District B served significantly more vitamin A and total fat in Period 1 and significantly more calories, iron, vitamin A, protein, and total fat in Period 2 than was planned. The major nutrients provided by the entree component included protein, calories, cholesterol, total fat, saturated fat, and sodium. Milk was an important source of calcium and provided approximately one-third of the total protein and vitamin A in the meal. The vegetable/fruit component was the major source of vitamins A and C. The grain/bread component provided approximately 20% of the carbohydrates among five meal components. The miscellaneous component affected the sodium and fat content of the menus. Menu planners can use the results of this study to enhance their knowledge of the nutrient contributions of each meal component and as inputs for planning menus that meet children's nutritional requirements.

BACKGROUND/OBJECTIVES: High levels of plasma low-density lipoprotein (LDL) cholesterol are an important determinant of atherosclerotic lesion formation. The disruption of cholesterol efflux or reverse cholesterol transport (RCT) in peripheral tissues and macrophages may promote atherogenesis. The aim of the current study was to examine whether bioactive ellagic acid, a functional food component, improved RCT functionality and high-density lipoprotein (HDL) function in diet-induced atherogenesis of apolipoproteins E (apoE) knockout (KO) mice. MATERIALS/METHODS: Wild type mice and apoE KO mice were fed a high-cholesterol Paigen diet for 10 weeks to induce hypercholesterolemia and atherosclerosis, and concomitantly received 10 mg/kg ellagic acid via gavage. RESULTS: Supplying ellagic acid enhanced induction of apoE and ATP-binding cassette (ABC) transporter G1 in oxidized LDL-exposed macrophages, facilitating cholesterol efflux associated with RCT. Oral administration of ellagic acid to apoE KO mice fed on Paigen diet improved hypercholesterolemia with reduced atherogenic index. This compound enhanced the expression of ABC transporters in peritoneal macrophages isolated from apoE KO mice fed on Paigen diet, indicating increased cholesterol efflux. Plasma levels of cholesterol ester transport protein and phospholipid transport protein involved in RCT were elevated in mice lack of apoE gene, which was substantially reduced by supplementing ellagic acid to Paigen diet-fed mice. In addition, ellagic acid attenuated hepatic lipid accumulation in apoE KO mice, evidenced by staining of hematoxylin and eosin and oil red O. Furthermore, the supplementation of 10 mg/kg ellagic acid favorably influenced the transcriptional levels of hepatic LDL receptor and scavenger receptor-B1 in Paigen diet-fed apoE KO mice. CONCLUSION: Ellagic acid may be an athero-protective dietary compound encumbering diet-induced atherogenesis though improving the RCT functionality.

In order to select the optimum ethanol concentration for extraction of volatile components in cinnamon, the dried cinnamon was extracted with water and 30∼90% ethanol. The volatile components of cinnamon extracts were isolated by the simultaneous distillation extraction method using Likens and Nickerson's extraction apparatus, and analyzed by GC-MS. In cinnamon bark powder 45 components were detected and 21 components were identified. The major component of cinnamon bark powder was cinnamic aldehyde. In water extract of cinnamon, volatile components were not extracted sufficiently. The volatile components of cinnamon were increased with the increment of ethanol concentraction upto 70%. The volatile component of 70% ethanol extract showed similar pattern and amount to cinnamon bark powder. But in 90% ethanol extracts, the number and amount of volatile component were reduced. The above data suggested that 70% ethanol was the most effective solvent for volatile components extraction of cinnamon.

In order to obtain the basic data for the preparation of yogurt containing ginseng component, the effect of ginseng component on cell growth of Lactobacillus casei YIT 9018 and on lactic acid production were investigated. Initial cell growth and acid production were markedly inhibited by the addition of ethanol extracts in the level of 8% into 15% skim milk. Crude saponin did not show any inhibitory effect on cell growth and acid production, but ether layer fraction showed inhibitory effect. It was thought to be more advantageous to add ginseng extracts after the fermentation of milk than before. The addition of ginseng extract at 8% level into liquid yogurt was most suitable in organoleptic test. Cell viability was not affected by the addition of ethanol extracts up to 8% level during storage of liquid yogurt.

The purpose of this study was to investigate the correlation between serum component and immune function in Korean female college students according to the body mass index. There were significant increased in weight, body fat, LBM, TBW, WHR in subjects as their BMI increase(p<0.001). It was found obese group had higher levels of serum components such as total cholesterol, LDL-cholesterol and Cu levels than those of the normal group. There was a significant positive correlation between HDL-cholesterol level and NK cell number(p<0.01), between A/G ratio and T lympocytes number(p<0.05), between Cu levels and B lympocytes(p<0.01) in normal group. There was a significant positive correlation between TG level and CD4/8 ratio(p<0.001), between and IgG(p<0.001) in obese group.
