The objectives of this study were to identify the dietary patterns associated with hypertension among Korean males. Data from the 2001 Korean National Health and Nutrition Survey of 1,869 men aged 20-65 years were used for the analysis. As an initial analysis, a factor analysis was applied to identify major dietary patterns among the subjects. Then logistic regression analysis was conducted to identify the pattern related with hypertension. As a result of the initial analysis, three major dietary patterns were identified. Dietary pattern 1 (traditional) was heavily loaded with vegetables, fish and cereal. Dietary pattern 2 (Western) was loaded with fast foods, bread, meats and dairy products. Dietary pattern 3 (Drinker) was loaded with mostly pork, beer and soju (Korean liquor). From the second stage of the analysis, there was a tendency of positive association between traditional patterns and hypertension risks. However, the tendency did not meet statistical significance level (p<0.05). In summary, unlikely findings from European and American studies, vegetables rich traditional dietary patterns did not show any protective effect on hypertension in Korean males. The Korean dietary practice, which is consuming salted vegetables instead of fresh vegetables, might have played a role in these findings. However, the full explanation of the findings remained to be answered with further investigation since none of the dietary patterns identified showed any statistical significance.
The present study was conducted to investigate the feasibility of feeding neem kernel meal (NKM) containing diet to growing Japanese quails, which was incorporated into a standard quail diet at 0, 50, 75 or 100 g/kg in place of soyabean meal and deoiled rice bran. Each diet was offered to 30 quail chicks housed in battery cages from day one to five weeks of age. The chicks fed NKM diets gained 123.3, 122.6 and 121.6 g mean body weight, respectively, and which were significantly (p<0.05) lower than that of 129.9 g gained by those of birds fed the control diets. The feed intake and feed conversion ratio of birds in different dietary groups were not significantly altered due to dietary variations. Mean values for retention of dietary energy, N and Ca were found to insignificantly differ (p>0.05) among the treatment groups but P retention was significantly (p<0.01) lower for quails fed 100 g/kg NKM than those in other groups. Blood biochemical constituents, carcass characteristics and organoleptic test for meat also were not found to vary significantly (p>0.05) due to dietary treatments. The histopathology of liver and kidney tissues from NKM fed quails revealed mild degenerative changes. It could be concluded that inclusion of NKM in quail diet reduced the growth besides inducing mild pathological changes in liver and kidney tissues.
The purposes of this research were to assess dietary fatty acid patterns and to elucidate the relationship between the serum cholesterol levels and dietary fatty acid patterns, plasma fatty acid compositions, BMI (body mass index), and other lipid profile. The subjects were 151 adults aged 23 to 80 years, selected from the Outpatient Clinic and Cardiova-scular Department of the Seoul Municipal Hospital. Dietary data were obtained using three day food records. Sixteen dietary fatty acids were analyzed using Korean and US nutrient databases. The subjects were divided into three serum cholesterol levels: desirable (< 200 mg/dl, N = 44), borderline-risk ($\geq$ 200 - < 240 mg/dl, N = 35), and high-risk ($\geq$ 240 mg/dl, N = 72) groups. The high-risk group had higher BMI, waist, and waist to hip ratio (WHR) than the desirable and borderline-risk groups. Serum concentrations of triglyceride, LDL cholesterol and LDL/HDL cholesterol ratio were significantly higher in the high-risk group as compared to those in the other two groups. The serum cholesterol levels were highly correlated with BMI (r = 0.435), triglyceride (r = 0.425) and LDL/HDL cholesterol (r = 0.870) ratio. The highest fatty acid intake was from oleic acid (33 - 34% of total fatty acid intakes), which was followed by linoleic acid (27%), palmitic acid (19%), and stearic acid (7%). There was no correlation between the serum cholesterol levels and the dietary fatty acid intakes, polyunsaturateumonounsaturateusaturated fatty acids (P/M/S) and $\omega$6/$\omega$3 ratios. The correlation between plasma fatty acids such as myristic acid, oleic acid, linoleic acid, and docosahexaenoic acid and serum cholesterol levels was also weak.

Two dietary experiments were performed to evaluate the impact of the herb Mentha piperita as a dietary supplement on Catla catla. In Experiment 1, fingerlings (0.45-2.60 g) were fed on diets supplemented with M. piperita at different levels (P1, P2, P3, and P4 at 2, 4, 6, and $8g\;Kg^{-1}$ of feed) and C1 served as the control with no peppermint supplementation. In Experiment 2, fingerlings (0.40-3.15 g) were fed with diets containing autochthonous probiotic bacteria Bacillus coagulans (3000 colony forming unit $g^{-1}$) along with M. piperita (PP1-PP4 at 2, 4, 6, and $8g\;Kg^{-1}$ of feed) and feed C2 served as control containing probiotics but no peppermint. Significantly (P < 0.05) high values of growth parameters, digestive enzyme activities, low reed conservation ratio, low excretion of ammonia, and orthophosphates were observed in fingerlings fed with P3 for Experiment 1 and PP3 for Experiment 2. Hematological counts, phagocytic activity, and respiratory burst activity were also enhanced in fingerlings fed with M. piperita supplementation revealing that dietary administration of peppermint at optimum level can enhance the growth, digestibility, and immunity of C. catla fingerlings; however, incorporation of B. coagulans showed better growth and immunity revealing that synergistic effects of M. piperita and autochthonous probiotic in C. catla diets can lead to its sustainable aquaculture.
This study was performed to develop a standardized recipe for yuza pyun made of citron juice that is by-product of citron tea, to increase the utilization of citron. The effects of mungbean starch(15%, 18%) and dilution ratio of yuza extract(100%, 75%, 50%) on the quality characteristics were evaluated. The quality characteristics of the samples were estimated in terms of sweetness, color difference, texture profile analysis and sensory evaluation. Sweetness of the 18% mungbean groups were higher than 15% groups(p<0.001). The values of Hunter color system indicated that higher content of yuza extract tended to increase yellowness significantly(p<0.001). Texture profiles of hardness, adhesiveness, springiness, cohesiveness, gumminess of yuza pyun showed no significant differences among samples. For sensory evaluation, color and sourness were decreased as yuza extract was diluted, whereas elasticity and sweetness were increased. Yuza pyun containing 18% of mungbean starch with 50% diluted extract was the most preferred in overall acceptability. According to multiple regression analysis, color, sweetness, elasticity and sourness(in order) were important control factors in overall acceptability.
This study was performed to investigate effects of dietary folic acid supplementation on plasma homocysteine levels, thiobarbituric acid reactive substance s (TBARS) level s and liver SAM/SAH ratio in hyperhomocysteinaemia-induced pregnant rats. Forty-two female Sprague-Dawley rats were divided three groups (C: control diet, HFD: $0.3\%$ homocystine and 0 mg folic acid diet, HFS: $0.3\%$ homocystine and 8 mg/kg folic acid diet) according to homocystine and folic acid levels in the diet. They were fed experimental diets for 5 weeks prior to the mating and also during the entire period of pregnancy till gestational day 20. Dietary folic acid supplementation caused a significant decrease in plasma homocysteine levels which had been increased by a homocystine-diet, with a concomitant increase in plasma and liver folate levels. Liver TBARS levels in homocysteine-folic acid-deficient group (HFD) were higher than those in control group. Dietary folic acid supplementation increased hepatic SAM/SAM ratio in homocysteine-folic acid- sopplemetantion group (HFS) when compared to the HFD (p < 0.05). These data suggest that folate depletion and elevated plasma homocysteine may promote oxidative stress in rat livers and influence the remethylation cycle of the homocysteine metabolism detrimentally. In conclusion, dietary folic acid supplementation was found to be effective for lowering plasma homocysteine levels, relieving oxidative stress, and improving the methylation status in the body.
This study was conducted to evaluate the effects of dietary complex enzyme (${\beta}$-mannanase 800 IU/kg and xylanase 700 IU/kg) in a diet containing corn distiller's dried grain with soluble (DDGS) on meat quality and pork fatty acid composition. Ninety-six pigs ([(Landrace${\times}$Yorkshire)${\times}$Duroc], with an average body weight of 68.77 kg were used in the 8 wk growth assay. Dietary treatments included 1) corn-soybean meal diet, 2) corn-soybean meal diet + 0.05% enzyme complex, 3) cornsoybean meal diet with DDGS and 4) corn-soybean meal diet with DDGS + 0.05% enzyme complex. The pigs were allotted randomly into pens (n=4 per pen) with six replicate pens per treatment by a completely randomized design. Pigs were slaughtered at the end of the experiment and the loin muscle was obtained for meat quality. Meat pH (p<0.01), firmness (p<0.01) and redness (p<0.05) were higher in DDGS-supplemented diet than in the corn-soy bean meal diet. However, color, marbling, lightness, yellowness, thiobarbituric acid reactive substances, water holing capacity, driploss, cooking loss and loin muscle area were not significantly different among the diets. The pigs fed the DGGS-supplemented diet had higher total unsaturated fatty acids (UFA) and total UFA/saturated fatty acid (SFA) ratio of loin and backfat. The results indicate that a diet containing DDGS can influence pH, firmness, redness and total UFA concentration and total UFA/SFA ratio of meat and backfat, but that enzyme addition has no affect on meat quality.
Body content bone mined density and nutrient intake status of 129 college women in Daegu area are analyze4 The mean age was 23.1 years. Bone mineral density was measured in their right heel by SONOST-2000 ultrasound bone densitometer, and nutrient intake was assessed by a Questionnaire. Diet intake data were obtained by using a 24 hours recall method to evaluate the subject's usual diet. The average energy, Ca, Ee, Zn and folate intakes were 64.2, 47.5, 54.7, 62.9 and $57.4\%$ of RDA, respectively. Ca/P and Ca/Protein ratio were 0.46 and 6.7, respectively. The mean adequacy ratio(MAR), an index of overall dietary quality wag 0.6. The index of nutritional quality was under 1.0 for protein(0.7), vitamin A(0.9), E(0.7), $B_1(0.8)$, niacin(0.8), $B_6(0.6)$ and phosphorus(0.6). The less the protein and energy intake, the less the bone mineral density(p<0.05). The intakes of protein(p<0.05) and that of phosphorus(p<0.001) were positively correlated with bone quality index(BQI). The calcium intake was positively correlated with Z-score(p<0.05). The phosphorus intake was positively correlated with T-score(p<0.001) and Z-score(p<0.0001). In conclusion, this study indicates that nutrient intake of the college women is considerably lower than the RDA. Also the BQI is lower than standard.

In livestock nutrition, natural feed additives are gaining increased attention as alternatives to antibiotic growth promoters to improve animal performance. This study investigated the effects of dietary turmeric supplementation on the growth performance and gut health of weaned piglets. A total of 48 weaned piglets (Duroc × [Landrace × Yorkshire]) were used in a 6-week feeding trial. All piglets were allotted to two dietary treatments: corn-soybean meal basal diet without turmeric (control) and with 1% weight per weight (w/w) turmeric powder (turmeric). The results showed that dietary inclusion of turmeric with the basal diet improved final body weight and total average daily gain (p < 0.05). The concentrations of short-chain fatty acids in the fecal samples, including acetic, butyric, and propionic acids, were higher in the turmeric group (p < 0.05). The villus height-to-crypt depth ratio was higher in the ileum of turmeric-fed piglets (p = 0.04). The 16S rRNA gene sequencing of fecal microbiota indicated that, at the phylum level, Firmicutes and Bacteroidetes were the most predominant taxa in all fecal samples. Bacteroidetes were significantly decreased in the turmeric group compared to the control group (p = 0.021). At the genus level, turmeric showed a decreased abundance of Prevotella (p = 0.021) and an increasing trend of Lactobacillus (p = 0.083). Among the total detected species, nine bacterial species showed significant differences between the two groups. The results of this study indicated that turmeric altered the gut microbiota and shortchain fatty acid production. This suggests that turmeric could be used as a potential alternative growth promoter for piglets.
This study was aimed to investigate whether or not black soybean supplements affect levels of lipid profiles and female hormone (estradiol; E2, estrogen; Es) in 57 middle-aged women (in their 40s and 50s). All subjects were randomly assigned to the control or black soybean supplement group (BSS group). The BSS group was allocated to use dietary black soybean supplements (100 g/day) for 8 weeks. The BSS subjects were divided into two subgroups; 14 women were in the premenopausal group and 15 were in the postmenopausal group. We measured lipid profiles, female hormones and nutrient intakes at 0 weesk and 8 weeks. After 8 weeks, high-density lipoprotein (HDL) cholesterol was significantly decreased (P<0.01) and the athrogenic index (AI) was significantly increased (P<0.01) in control group. In BSS group, triglyceride (TG) (P<0.05), low-density lipoprotein (LDL) cholesterol (P<0.01) and LDL-HDL ratio (LHR) (P<0.01) were significantly decreased. However, E2 and Es were significantly increased (P<0.01). Compared to the control group, the BSS group revealed statistically significant improvements in the levels of TG, HDL-cholesterol, AI, LHR, E2 and Es (P<0.05). In the premenopausal group, HDL-cholesterol (P<0.05), E2 (P<0.01) and Es (P<0.05) were significantly increased and AI (P<0.01) and LHR (P<0.01) were significantly decreased after 8 weeks. In the postmenopausal group, E2 (P<0.05), and Es (P<0.05) were significantly decreased. However, total cholesterol (TC) was increased (P<0.01). Compared to the postmenopausal group, the premenopausal group was significantly improved on HDL-cholesterol, LDL-cholesterol and LHR (P<0.05). In conclusion, black soybean supplements may have beneficial effects on improving lipid profiles and female hormones.
