This study was conducted to investigate breakfast consumption pattern in relation to diet quality and health outcomes of Korean adults. Data are from 2001 National Health and Nutrition Survey. Dietary information of 3406 adults aged $30{\sim}49$ years and their socio-demographic characteristics, blood lipid profile, fasting blood glucose, blood pressure, anthropometric measurements were analyzed. According to the breakfast consumption of the subjects, they were classified to breakfast skippers and eaters and the eaters' breakfast staple types were defined as RICE, BREAD, NOODLES, MIXED (mixed types including several grain-based dishes), and OTHERS. The proportions of breakfast consumption patterns were 18.4% for skippers, 71.1% for RICE, 2.6% for BREAD, 1.6% for NOODLES, 4.0% for MIXED, and 2.4% for OTHERS. Breakfast skippers had lower daily nutrients intake than breakfast eaters but their health outcomes did not differ from those of eaters. Instead, men with BREAD pattern had higher blood cholesterol and women in NOODLE pattern had higher blood glucose and lower HDL cholesterol. The BREAD pattern breakfast had higher energy contribution from fat and lower nutrient densities and the subjects in BREAD pattern had higher level of household income. Men's BREAD pattern breakfast consisted more animal products than that of women. There was high probability of undernutrition among women in NOODLE pattern and their mean household income was the lowest. From these results, in Korea, breakfast staple types have different food patterns and there was need for developing healthy food patterns appropriate to each staple type. The breakfast consumption pattern had influences on nutrient adequacy of the diet and health outcomes and seemed to represent socio-economic status. These could be used in doing nutrition education in community.
The aim of investigated the role of FABP5 in the hepatic lipogenesis and lipid metabolisms. Mice were overexpressed and silenced liver FABP5 using virus particles. Mice were fed a Western-type diet or regular chow for 1week and then sacrificed mouse after 24hr fasted. Liver homogenates were used for protein analysis by Western blot and mRNA levels by RT-PCR. Hepatic and serum lipids were analysed by thin-layer chromatography. Mice fed a Western-type or high saturated fat diet revealed large increases in FABP5 expression. However, FABP5 mRNA levels were drastically reduced under fasted. Hepatic TG was significantly increased FABP5-OEAV mice, but a significantly decreased hepatic free cholesterol under fed. The discovered a substantial decrease in hepatic TG mass with FABP5 silencing. In these data, presented evidence for an important role of FABP5 in hepatic lipogenesis and hepatic TG storage. FABP5 may also be a potential target in the treatment of NAFLD, metabolic syndrome, and obesity. Furthermore, studies to which transcription factors are involved in FABP5 expression and regulation.
Purpose: The atherogenic index of plasma (AIP) is gaining recognition as a superior predictor of coronary artery disease. This study examined the relationship between the AIP and the intake of various food groups in Korean adults, using the baseline data from the Korean Genome and Epidemiology Study-The Health Examinees (KoGES-HEXA) study. Methods: This study included 133,381 adults (46,288 men, 87,093 women) who completed the nutrition survey and biochemical tests of the KoGES-HEXA study. The AIP was calculated as the log (triglycerides/high-density lipoprotein-cholesterol) and was divided into quintiles according to sex for further analysis. Data on food group intake were obtained using the semi-quantitative food frequency questionnaire, and daily food group intake (g/d) was evaluated for each individual. The association between the food group intake and the AIP was examined using the linear regression analysis after adjusting for the confounding variables. Results: In this study population, there was a positive correlation between energy intake and the AIP in men whereas an inverse assocation was shown in women (p < 0.001). In women, a rise in the AIP significantly correlated with an increased percentage of energy intake derived from carbohydrates but decreased percentages of energy from protein and fat (p < 0.001). In men and women, the consumption of grains and kimchi/pickles increased as the AIP rose, while the intake of legumes, nuts, meat and its products, eggs, fish, and milk and dairy products decreased. Among men, individuals in the highest AIP group showed higher intake of wheat products than those in the lowest group of the AIP. In women, the AIP was inversely correlated with potatoes and beverages consumption. Conclusion: This study highlights the importance of a balanced diet, including various protein sources, milk and dairy products, legumes, and nuts, for preventing cardiovascular diseases. Further research into sex-specific dietary patterns is essential for tailoring appropriate dietary recommendations.

This study investigated the ability of extracts from Lentinus edodes (LE) and rice with Lentinus edodes mycelium (LEM) to inhibit diabetes and obesity. Lipid accumulation significantly decreased by 78% and 74% upon treatment with 300 ${\mu}g/mL$ of LE and LEM, respectively (p<0.01). Cholesteryl ester transfer protein (CETP) inhibition activity increased by 94% and 99% upon treatment with 300 ${\mu}g/mL$ of LE and LEM, respectively. In order to investigate the effect of LE and LEM on diabetes, the inhibition of protein tyrosine phosphate 1B (PTP1B) activity from the LE and LEM extracts at various concentrations (1, 3, 10, 30, 100, 300 ${\mu}g/mL$) was assessed. PTP1B activity by treatment with 10, 30, and 100 ${\mu}g/mL$ of LE, was inhibited at a rate of 7, 9, and 7% respectively. Also, PTP1B activity from treatment with increasing concentration of LEM led to a significant concentration-dependent inhibition of PTP1B activity (p<0.01). LE and LEM were orally administered for 28 days after a high fat diet (HFD). LE and LEM significantly reduced triglyceride, cholesterol, HDL-cholesterol and LDL-cholesterol levels. GOT and GPT were not significantly effected. These results indicate that extracts of LE and rice with LEM have potent activities useful in the treatment of obesity and diabetes mellitus.

The objective of this study was to examine the ability of extracts from Phellinus linteus (PL) and rice with Phellinus linteus mycelium (PLM) to inhibit obesity and diabetes. The efficacy of PL and PLM were evaluated using Oil Red O staining, cholesteryl ester transfer protein (CETP) levels, protein tyrosine phosphate 1B (PTP1B) levels, organ weight, and serum lipid levels. Lipid accumulation significantly decreased by 76% and 59% upon treatment with $300{\mu}g/mL$ of PL and PLM, respectively (P<0.01). The inhibition of CETP activity increased 99% upon treatment with $300{\mu}g/mL$ of PL or PLM. Treatment with 3, 10, 30, 100, and $300{\mu}g/mL$ of PL, changed PTP1B activity by 10, 11, 14, 12, and 18% respectively. Also, treatment with increasing concentrations of PLM led to a significant concentration-dependent inhibition of PTP1B activity (P<0.01). PL and PLM were orally administered for 28 days after a high fat diet (HFD). PL significantly (P<0.05) reduced triglyceride and cholesterol levels. In addition, PLM significantly (P<0.05) reduced triglyceride, cholesterol, and HDL-cholesterol levels. GOT and GPT were not significantly affected. These results indicate that PL and PLM extracts have potent and useful activities for the treatment of obesity and diabetes mellitus.
The objectives or this study were to examine reed value or waste onion in duck. Experimental chicks (Cherry Valley F$_1$, 1day old, 350 chicks) were randomly assigned in 8 treatment groups, each 45 chicks, and man-aged for 7 weeks (3 kg BW, 49 days old). Treatments were control, 3%, 6% of chopped onion-fed, 5%, 10% of onion extract fed, 6% of onion meal, 3%, 6% of fermented onion-fed. Feed intake was significantly (P<0.05) high in control group, but ADG was high in 3% chopped onion-fed group. Feed requirement was very efficient in all treatment groups except 6% fermented onion-fed group. Dressing rate was high in 5% onion extract-fed group, but it was not significant. Abdominal fat was the highest in control and 6% fermented onion-fed group and lowest in 6% chopped onion-fed group. Cholesterol content was lower in all treatment groups than in control group, but it was not significantly different. Stearic acid ($C_{18:0}$) content was significantly low in all treatment group (P<0.05). However, arachidonic acid ($C_{20:4}$) content was higher in treatment group than in control group. In result, onion diet was not significantly effect on palatability, feed intake, ADG in ducks. Duck meat of onion-fed contained low cho-lesterol and high unsaturated fat content.

Persimmons are shown to contain high levels of phenolics. The present study was designed to investigate if a sweet persimmon wine (SPW) would affect the development of alcoholic fatty liver in rats. Initially, male Sprague-Dawley rats were housed singly in stainless steel wire-bottomed cages in a room of controlled temperature and lighting. The rats had free access to a nutritionally adequate AIN-93G diet and deionized water. After the acclimatization period, rats were weight-matched and assigned to the following three groups: two groups were fed 6.7% ethanol or the caloric equivalent of maltose-dextrin in a Lieber-DeCarli diet and the other group was fed the isocaloric Lieber-DeCarli diet containing SPW at the same ethanol level. All three groups were fed their respective diets for 6 weeks. Serum transaminase, cholesterol, and triglyceride levels were measured. Liver lipids and histology were assessed at 6 weeks. The total phenolic content and the antioxidant and free radical scavenging activities of SPW were determined. SPW significantly increased antioxidant and free radical scavenging activities. As markers of liver injury, serum alanine and aspartate transminases were markedly lowered by SPW at 6 weeks. SPW significantly reduced the serum levels of serum cholesterol and triglyceride compared to ethanol treatment. SPW delayed the development of an alcoholic fatty liver by reversing fat accumulation in the liver, as evidenced in histological observations. Taken together, SPW seems to protect the liver from becoming fatty by alleviating fatty liver symptoms and lowering hepatic and serum lipid levels. Such a protective effect of SPW appears to be in part due to its phenolics.

This study was conducted to investigate the effects of various levels of chitosan oligomer (CO) molecular weight on the disorders of lipid metabolism and immune-related factors induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), that is a endocrine disrupter, using adult male rats (SD) for 3 weeks. These 40 animals were divided into five groups. Three kinds of CO were used by molecular weight (MW) (less than 1000, 1000~3000, and 5000~10000) and added 4% to basal diets respectively. TCDD (40 ${\mu}g$/kg B.W) was intraperitoneally injected into rats at the beginning of the experiment. The relative weights of the livers were increased in all rats treated with TCDD, and the brain and testis weights were increased in all CO diet groups, compared to the control and TCDD groups. The levels of white blood cells (WBC) and red blood cells (RBC), hemoglobin, hematocrits (HCT), and platelets were significantly lowered by treating TCDD. By the way, RBC and HCT tended to recover by CO diets. The elevation of serum total and HDL cholesterol levels induced by TCDD treatment was significantly reduced by CO (5000~10000 MW) diets. The apparent increasing of the total lipid, cholesterol, and triglyceride levels of rat livers induced by TCDD was tended to be suppressed in those fed CO diets. Especially, diets with less than 1000 MW significantly diminished liver triglycerides. The levels of serum immunoglobulin (Ig) A, IgG1 and IgM were significantly high in rats fed CO (5000~10000 MW) diets. The decreasing levels of IgE by treatment with TCDD tended to recover all the CO diet groups to the level of control group. In histochemical observation, the fat droplets and apoptosis of liver due to TCDD treatment were markedly alleviated in all CO diet groups. These results indicated that CO, though not regular according to molecular weight, can exert improving effects on lipid accumulation, hepatocytic disorders, abnormal blood cells, and some immunoglobulins induced by TCDD.
This study was conducted to determine the effects of dietary supplementation with chitosan feeding levels and feeding forms on the performance, proximate composition, pH, thiobarbituric acid reactive substance (TBARS), water holding capacity (WHC), shear force, meat color, and fatty acid of chicken thigh meat. Two hundred broilers (Arbor Acre Broiler, male) were randomly assigned to five groups and were fed for five weeks and slaughtered. Thigh muscle was evaluated in this experiment. The amounts of proximate composition, crude fat of control and T3 for the chitosan-treated groups were significantly higher as compared with T2 (P<0.05), but no significant effects were detected on moisture, crude protein, and crude ash. By comparison, pH was significantly increased when chitosan was included at 2% into diet or more than 1% into drinking water. TBARS was significantly lower at chitosan treated groups it was decreased with increasing chitosan level in the diets (P<0.05). Therefore, chitosan had the possibility to improve shelf life of chicken meat. Higher chitosan levels and feeding additive increased high density lipoprotein cholesterol (HDL-C) and reduced total cholesterol and low density lipoprotein cholesterol (LDL-C) (P<0.05). $L^*$ and $a^*$ of chitosan treated group was higher than the control. As the dietary chitosan levels increase, the composition of palmitic acid and oleic acid levels was increased, however, those but the rates of linoleic acid and arachidonic acid were decreased. It is concluded that dietary chitosan has a positive effect on increasing HDL-C and oleic acid and decreasing total-C, LDL-C and TBARS values. Therefore, the treatment with the most significant effects in the current study was the high level of chitosan.
In order to investigate the effect of dietary fatty acids on lipids metabolism in adipose pads and superficial pectoral muscle of chicks, the present, experiment was carried out using signle comb White Leghorn male chicks fed a fat-free diet and diets containing margaric, stearic or linoleic acids. Total lipids of tissues were extracted with a chlorofrom-methanol solution. The lipid components were fractionated by thin layer chromatography and the fatty acid distribution of lipid fractions was determined by gas liquid chromatography. The neck adipose pads contained 34-62% total lipids, in which triglycerides, were dominant, being 97-98%. Margaric, stearic and linoleic acids were distributed at a relatively high rate in the adipose tissue when the corresponding acids were fed, and margaric acid feeding lowered palmitoleic acid distribution and linoleic acid feeding elevated stearic acid distribution. The wet superficial pectoral muscle contained 1.3-1.7% total lipids, of which 77-79% was phospholipids and 11-13% was free cholesterol. When margaric acid was fed, margaric and heptadecenoic acids appeared in the muscle lipids. When linoleic acid was fed, this acid was significantly highly distributed in every muscle lipid fractions, whereas, when stearic acid fed no elevation of stearic acid distribution was observed. In the muscle phospholipids, oleic acid was significantly highly distributed in the stearic acid fed chicks, and the linoleic acid feeding signigicantly lowered the distribution value of palmitic and oleic acids, but elevated the distribution value of stearic acid. And the linoleic acid feeding lowered the distribution value of eicosatrienoic acid and elevated the distribution value of arachidonic acid.
