The effects of the amount of red pepper intake per a day on the capsaicin threshold, nutrient intake, and anthropo-metric measurements were investigated in 100 female students of university. Three 24-hour recalls were performed to estimate usual nutrient and red pepper intake of free-living participants. The solutions containing capsaicin at concentration of 0.05, 0.1, 0.2, 0.3, 0.4, 0.5ppm used for the evaluation of hot-taste detection threshold. Subjects were asked to recognize the burning sensation after tasting l0ml of each test solution in ascending order of capsaicin concentrations. Mean intake of red pepper was 4.6 g/d and the capsaicin threshold was 0.27 ppm. The detection threshold for capsaicin was correlated with the amount of pepper intake per a day. Red pepper intake was correlated with energy, protein, lipid, carbohydrate, Iron, vitamin A, vitamin B$_2$ niacin, and vitamin E intakes. However, it was not correlated with intake of calcium, vitamin B$_1$ or vitamin C. The red pepper intake was negatively correlated with fat mass and waist girth and the capsaicin threshold was also negatively correlated with pulse. In conclusion, red pepper intake was associated with nutrient intake and capsaicin threshold whereas it was negatively correlated with fat mass and waist girth.

We examined the effects of 5 g red pepper powder in soup preload given at breakfast on food intake, blood pressure, body core temperature, hunger, fullness and thirst scores in 29 female collage students. All subjects received two kind of soup preloads in random order. After ingesting a soup, subjects ate other food items as a breakfast ad libitum. Two soups were of the same composition and volume but differed only in 5 g red pepper. So one soup designated as "beef-vegetable" and the other soup designated as "red pepper". Red pepper soup consumption significantly enhanced energy and macronutrient intake by 17%. The hunger scores after test meals were inversely correlated with energy and nutrient intake in beef-vegetable meal. However, the postprandial hunger scores were not correlated with energy and nutrient intakes in red pepper meal. The fullness scores at 90 min after the red pepper meal were inversely correlated with energy and nutrient intake whereas the fullness scores after beef-vegetable meal were not correlated with energy and nutrient intake. These results suggest that hot red pepper ingestion may desensitize some gastrointestinal vagal afferents and disturb feeling of hunger and fullness. The postprandial changes of body temperatures in red pepper meal were higher for a longer time in comparison with those in beef-vegetable meal. For the red pepper meal there frequently were higher correlations between blood pressures and anthropometric measurements, compared to those in beef-vegetable meal. These results might be explained partly by the enhancing effects of capsaicin on thermogenesis and sympathetic nervous system activity. It is concluded that the ingestion of spicy soup with red pepper can increase appetite, energy and nutrient intakes in Korean females, and this effect might be related to disturbed feeling of hunger and fullness.hunger and fullness.

Objectives: This study was conducted to estimate usual meat intake distribution, which may have been over/underestimated when estimations were made using only the third food codes of the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: For this purpose, 24-hour recall data from the 2009 Korea National Health and Nutrition Examination Survey, which conducted a partial 2-day survey of food intake, were used. The Multiple Source Method (MSM) was used to estimate the distribution of the usual intake of red and processed meats. Results: The results of this study show that the mean intake of red meat was 45.07 g while that of processed meat was 4.33 g. These results are slightly higher than the consumption calculated using only tertiary food code, and the difference was statistically significant. Furthermore, characteristics of the estimated usual intake distribution were a smaller standard deviation, increased lower percentiles, and decreased upper percentiles compared to the 2-day mean intake distribution for both red and processed meats. The proportion of individuals not consuming red meat decreased substantially from approximately 37% to 0.7%. The proportion of consumption that exceeded 90 g, which is the upper limit of red meat intake recommended by the National Health Service (NHS), was only approximately 10% in the distribution of usual intake. Conclusions: As the consumption of processed foods is expected to continuously increase, caution is needed regarding the processes used to calculate food (group) intake to avoid over/underestimation. Moreover, use of KNHANES data to calculate the proportion of the population at risk of insufficiency or excess intake of certain nutrients or food (group), based on one day intake that does not address within-individual variation, may lead to biased estimates.

1. Dry matter intake was significantly increased above the 30% red clover plant composition (p<0.05) as compared with 100% orchardgrass plant composition. However, there was a significant positive correlation (p<0.05) between the content of CP and dry matter intake, and was a significant negative correlation (p<0.05) between the content of NDF and dry matter intake. 2. Dry matter digestibility was significantly increased with the increase of red clover plant composition as compared with 100% orchardgrass plant composition (p<0.05). Digestible dry matter intake was significantly increased above the 20% red clover plant composition (p<0.05) as compared with 100% orchardgrass plant composition. However, there was a significant positive correlation (p<0.05) between the content of CP and digestible dry matter intake, and was a significant negative correlation (p<0.01) between the content of NDF and digestible dry matter intake. 3. Preference of herbage samples tended to markedly increased with the increase of red clover plant composition.

A study was performed to assess dietary intake and serum levels of $\beta$-carotene and the influence of preference for hot taste on $\beta$-carotene intake in Korean female college students. Daily intake of $\beta$-carotene was estimated with a questionnaire composed of food item of high $\beta$-carotene contents and the average daily intake level was 4089$\pm$2400$\mu\textrm{g}$. The major sources of $\beta$-carotene included carrot, pumpkin, spinach, tomatoes and red pepper powder. 14$\pm$10% of total dietary $\beta$-carotene intake was from foods containing red pepper powder. The average amount of red pepper powder added to bean sprout soupr were 0.32$\pm$0.34g. Subjects preferring hot taste added significantly larger amount of red pepper powder(p<0.05) than those not preferring hot taste. Subjects of the lowest quartile of $\beta$-carotene intake level showed the lowest precentage of subjects preferring hot taste. The average serum $\beta$-carotene concentration was 36.5$\mu\textrm{g}$/dl and large variation in the amount among the subject has been observed. The level of dietary $\beta$-carotene intake and serum $\beta$-carotene concentration of Korean female college students were not significantly correlated but both were higher than levels in reports from western countries. These results indicate that $\beta$-carotene intake levels of the subjects are adequate and the preference for hot taste affects $\beta$-carotene intake significantly.

In Australia, many cropping areas are affected by salt. In these regions, Chenopodiaceous plants, such as Atriplex, Kochia and Bassia spp have been planted to improve soil conditions. These plants have become invaluable feed resources for grazing animals in dry summers, but have a high sodium content. To assess the impact of high salt intake on grazing deer, two experiments were conducted. The first experiment used 30 fallow weaner deer to examine the effect of salt level in the diet on feed intake, water intake and body weight of fallow deer. Salt was added to lucerne chaff at 0, 1.5, 3.0, 4.5 and 6% and fresh water was offered all the time. Increasing the salt level in the diet from 0 to 6% didn't affect feed intake, osmotic pressure and mineral concentration in blood of fallow deer. However, water intake was significantly higher (p<0.05) in deer fed diets containing more than 3% salt. Body weight was lower (p${\leq}$0.056) for fallow deer in July and August when salt content was over 3%, suggesting they can ingest over 15 g sodium/day without significant depression in both feed intake and growth rate if the fresh water is available. In the second experiment, 18 red weaner deer were fed lucerne chaff diets containing 1.5, 4.5 and 6.0% salt with 6 deer/diet. The results revealed that feed intake and blood osmotic pressure were similar (p>0.05) for red deer fed different levels of salt although the feed intake declined from 1.91 to 1.67 kg with the increase of salt level from 1.5% to 6.0% in the diet. Water intake was significantly higher for deer fed diets containing over 4.5% salt, but there was no difference in body weight during the experiment. However, no recommendation can be made on the salt tolerance of red deer due to limited increment of salt level in the diet.

Under a typical Mediterranean environment in southern Australia, the evaporation rate increases significantly in hot summers, resulting in highly saline drinking water for grazing animals. Also in the cropping areas, dryland salinity is a problem. Grazing animals under these environments can ingest excessive amount of salt from feed, drinking water and soil, which can lead to a reduction in growth rate. To understand the impact of high salt intake on grazing deer, two experiments were conducted to assess the effect of salt levels in drinking water on feed intake and growth rate of red and fallow weaner deer. The results revealed that fallow deer did not show any abnormal behaviour or sickness when salt level in drinking water was increased from 0% to 2.5%. Feed intake was not affected until the salt content in water exceeded 1.5%. Body weight gain was not affected by 1.2% salt in drinking water, but was reduced as salt content in water increased. Compared with deer on fresh water, the feed intake of red deer on saline water was 11-13% lower when salt level in drinking water was 0.4-0.8%. An increase in salt level in water up to 1% resulted in about a 30% reduction in feed intake (p<0.01). Body weight gain was significantly (p=0.004) reduced when salt level reached 1.2%. The deer on 1% salt tended to have a higher (p=0.052) osmotic pressure in serum. The concentration of P, K, Mg and S in serum was affected when salt level in water was over 1.0%. The results suggested that the salt level in drinking water should be lower than 1.2% for fallow weaner deer and 0.8% for red weaner deer to avoid any reduction in feed intake. Deer farmers need to regularly test the salt levels in drinking water on their farms to ensure that the salt intake of grazing deer is not over the levels that deer can tolerate.

Background: While the incidence of non-Hodgkins lymphoma (NHL) has been rising worldwide, the reasons remain undefined. Recent research has focused on effect of red andf processed meat intake as a risk factor, but with inconclusive results. We therefore conducted a meta-analysis of data published to date, to ascertain the overall association between intake and NHL. Materials and Methods: A published literature search was performed through Pubmed, Cochrane Library, Medline, and Science Citation Index Expanded databases for articles published in English. Pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated using random or fixed effects models. Heterogeneity was assessed using Chi-square and I2 statistics. Dissemination bias was evaluated by funnel plot analysis.We performed a formal meta-analysis using summary measures from these studies. Results: In total, 11 published studies were included in the final analysis. The combined analysis revealed that there was significant association between the red meat and NHL risk (OR=1.10, 95%CI: 1.02 to 1.19, p=0.01). Additionally, there was showed significance association between processed red meat and NHL risk (OR=1.17, 95%CI: 1.06 to 1.29, p=0.001). In subgroup analysis, a statistical significant association was noted between diffuse large B-cell lymphoma (DLBCL) (OR=1.20, 95%CI: 1.04 to 2.37, P=0.01) and red meat intake. Conclusions: In this meta-Analysis, there was evidence for association between consumption of red meat, or processed meat and risk of NHL, particularly with the DLBCL subtype in the red meat case.

This study was carried out to measure the amount of daily intake on three synthetic food red colors (Amaranth: R2, Erythrosine: R3, Allura Red: R40) in foods by Korean. Analysis of three synthetic food red colors was conducted by HPLC with the foods including bread, confection, candy, alcoholic beverage, soft drink, ice cream, chocolate, and chewing gum. Recovery rates from the known concentrations of three standard food red colors which were spiked into foods were ranged from 85.1 to 100.4 (%) for each foods. Total Estimated Daily Intake (∑EDI) was from 0 to 1.632 mg/kg bw/day for each food item and from 0.512 to 7.281 mg/person/day for ages (1∼over 65 years old). The data of average food intake for each food item per person per day were obtained from the report of Korean National Nutrition Survey conducted by the Korea Ministry of Health and Welfare in 2001. Total EDI of each red colors per person per day were showed as follows; 0.742 mg/kg bw/day for R2, 0.391 mg/kg bw/day for R3 and 2.018 mg/kg bw/day for R40 as total amount respectively, and the ranges of these values were 0.5∼7.1% of FAO/WHO's Acceptable Daily Intake (ADI) values. Therefore, the amount of daily intake of three synthetic food red colors in Korea was regarded as safe.

In the present study, we investigated whether a gross deletion in the nef gene ($g{\Delta}nef$) is induced by Korean red ginseng (KRG) intake. Ten patients were treated with KRG powder for 3 years in the absence of antiretroviral drug therapy. On average, $3,555{\pm}1,042\;g$ KRG was administered per person over $36.1{\pm}2.4$ months. There was a mild decrease in CD4 T cell count ($75{\pm}110/{\mu}L$) over the $36.1{\pm}2.4$ months (p = 0.059). We obtained 355 nef amplicons using 71 peripheral blood mononuclear cell samples over a 3-year period. All ten patients exhibited g${\Delta}$nef (range, 3.2 to 45.9%). At baseline, 3 of 78 amplicons (3.8%) exhibited $g{\Delta}nef$, whereas 18.8% (52/277) revealed $g{\Delta}nef$ during KRG-intake (p<0.001). The proportion of $g{\Delta}nef$ was significantly correlated with monthly dose of KRG (r=0.89, p<0.001). The median time for first detection of $g{\Delta}nef$ was 13 months. In conclusion, our data show that $g{\Delta}nef$ is inducible by KRG intake and its proportion is dependent on the duration of KRG intake and dose of KRG.
