The relationship between socio-economic status and food and nutrient consumption patterns was studied in 7,370 Koreans aged 20 years and older in the 1995 Korean Health and Nutrition Survey. The aim of this study was to investigate the effect of rapid economic growth on food and nutrient consumption for Korean adults in the last 30 years. Monthly household income, and individual's educational level and occupation were chosen as variables of socio-economic status for individuals. A one day 24 hour recall method was used for the dietary survey. One way analysis of varience was adopted to test tole association between socio-economic variables and food and nutrient consumption patterns. Individuals who had a high socio-economic status had significantly higher daily intake of most of the nutrients including calcium, vitamin A, vitamin B$_2$which reached above the recommended dietary allowances(RDA) and a higher percentage energy consumption from fat. In addition, individual who belonged to a low socio-economic status consumed less animal foods, including meat, egg, milk and consumed low proportion of energy from fat. The results suggest that in spite of rapid economic growth during the last 30 years in Korea, individuals who belonged to low sorio-economic status categories are still nutritionally vulnerable. Among the sorio-economic variables, income and education except occupation were the influential factors on the food and nutrient consumption of Koreans. Therefore, nutrition policy should focus on influencing the dietary patterns of lower social class individuals to improve the health status of the population as a whole.

The present study was conducted to analyze the status of food and nutrients intakes of the colorectal cancer patients in the Daegu$\cdot$Kyungpook area and to find dietary risk factors related to the occurrence of colorectal cancer in this community. The case subjects (123) were selected from the patients recently diagnosed as colorectal cancer at Kyunrpook National University Hospital, the control subjects (182) were selected from the patients of the Department of Orthopedic Surgery at the same hospital and from the healthy volunteers who did not have any gastrointestinal diseases. The food consumption survey was done by individual interviews using semi-quantitative food kequency questionnaire and nutrients intakes were analysed by CAN program. The results of the study suggested that dietary factors which are speculated as the risk factors of colorectal cancer in Daegu$\cdot$Kyungpook area were high consumption of cereals and oils low consumption of fruits and mushrooms, high consumption of energy and fat, especially animal fat, low consumption of dietary fiber, high percentage of energy intake from cereals and potatoes, high intakes of protein, fat, vitamin A and cholesterol from egg, low intake of calcium from vegetables, and high intake of iron from meats and eggs. These findings might be useful for the nuation education to prevent colorectal cancer in the community. However it is recommended to conduct more extensive and systematic survey to reconfirm these dietary risk factors under taking into consideration of the dietary characteristics in this region.

This study was conducted to investigate nutrient consumption by Korean adults in various places. To accomplish this, we used the 1998-2009 Korea National Health and Nutrition Examination Survey (KNHANES). Subjects of this investigation were over 19 years and the study included 37,160 people. The meals were categorized as breakfast, lunch, dinner, and snacks consumed at home, or while eating-out. Investigation of the rate of consumption at serving places based on daily meals and years showed that eating-out generally increased with time. The consumption of meals prepared at home was higher than that of meals consumed anyplace else in 1998, 2001, 2005, and 2007-2009. However, the rate of consumption of home meals decreased from 1998 to 2007-2009, while the rate of eating-out increased during this period. Annual nutrient intake according to serving places with respect to meals, energy, fat, and sodium were significantly lower in home meals than those consumed elsewhere in 2007-2009 relative to 1998. The sodium intake and energy distribution ratio of fat in meals consumed while eating-out increased significantly from 1998 to 2007-2009. The energy, fat and sodium intake and energy contribution ratio of fat consumed in meals at institutions was significantly higher in 2007-2009 than in 1998. Based on these results, additional research is required to develop guidelines for dietary life improvement at each serving place and to address education and policies for balanced nutrition intake.

Background: Dietary fat has been inconsistently associated with the risk of breast cancer. The purpose of this study was to examine the relationship between meat and animal and plant fat intake and breast cancer risk in subgroups by total lifetime physical activity, using data from a case-control study conducted in the Region of Western Pomerania, Poland. Materials and Methods: The study included 858 women with histological confirmed breast cancer and 1,085 controls, free of any cancer diagnosis. The study was based on a self-administered questionnaire including questions about socio-demographic characteristics, current weight and height, reproductive factors, family history of breast cancer and lifestyle habits. Unconditional logistic regression was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Results: High animal fat intake significantly increased OR from 1.7 times (OR=1.66, 95%CI=1.07-3.59) to 2.9 times (OR=2.9, 95%CI=1.37-6.14) independent of physical activity level, comparing the third versus the lowest quartile. Women with a high intake of red meat or processed meat and low physical activity showed increased risk of breast cancer: OR=2.70, 95%CI=1.21-6.03 and 1.78, 95%CI=1.04-3.59, respectively. The plant fat dietary pattern was negatively associated with breast cancer in sedentary women (OR=0.57, 95%CI=0.32-0.99). Conclusions: These results indicated that a diet characterized by a high consumption of animal fat is associated with a higher breast cancer risk in sedentary women, while consumption of plant fat products may reduce risk in the same group.

The purpose of this study was to investigate the relationship between alcohol consumption and nutritional status of university male freshman in Chungnam area. The total of 111 subjects took part in the study and, they were observed general characteristics, alcohol consumption status, and nutrient intake using questionnaires. The mean age, height, weight, and BMI of the subjects were 19.3 years, 174.3㎝, 65.2㎏, and 21.5㎏/$m^2$ respectively. The mean alcohol consumption, and energy intake from alcohol were 7.8g/day, 55.3kcal/day. A significant number of subjects(48.2%) answered their frequency of alcohol consumption was once 2 weeks. Only 4.6% of subjects answered never drink. In almost subjects, alcohol consumption have been stared since they were adolescents, and major type of alcoholic beverage was 'soju'. The mean energy intake was 1985.6kcal and, energy ratio from carbohydrate, protein, fat was 58 : 15 : 27. There were significantly positive correlation among alcohol consumption and, body weight(p<0.05), intake of food, (p<0.05), energy(p<0.001), animal fat(p<0.05), fiber(p<0.05), vitamin $B_2$(p<0.05) and niacin(p<0.05). The alcohol consumption period showed a significantly positive correlation with alcohol consumption per one time(p<0.05). In summary, high consumption of alcohol in subjects was observed. Also, increase of alcohol consumption was related to weight gain and nutritional imbalance. Therefore, it is need that nutrition education for prevention of high alcohol consumption in university freshman and adolescents.

Skin temperatures on 10 sites and rectal temperature at every 10 minutes, oxygen consumption at every 20 minutes were measured on 18 male subjects (ages between 14 and 47 years) after exposure to cold air at $15^{\circ}C$ for two hours in a climatic room. Total body fat measured by means of a skinfold method and ratio of body surface area (S) to body volume (V), S/V, were utilized as basis of observations. Surface area was calculated after DuBois equation and body volume was calculated by our original formula. In influencing on the heat loss from the body core to the cold environment, % fat showed inverse relations, whereas, S/V ratio showed direct relations. Thus these two factors acted antagonistically on the body heat loss. Local skin temperatures showed negative correlations with skinfold thickness on the same site, nemaly, on chest, r=-.567; on back, r=-.507; and on upper arm, r=-.353. The other 7 skin sites showed low correlations with % fat. Minimum mean weighted skin temperature (MWST) showed a negative correlation (r=-.443) with % fat, and showed no correlation with S/V ratio. Oxygen consumption in the cold air at $15^{\circ}C$ increased from the first measurement at 20 minutes after exposure and maintained the same increasing trend up to 120 minutes. ${\Delta}T_R$ was greater in tile lean subjects who showed a greater % change in oxygen consumption. The antagonistic actions of % fat and S/V ratio on the heat loss were manifested by observations as follows: minimum rectal temperature was higher In fat subjects (r=.600) and lower in subjects with a greater S/V ratio (=-.582), ${\Delta}T_R$ was smaller in fat subjects (r=-.738) and greater in subjects with a greater S/V ratio (r=.618). Temperature difference between body core and skin surface (minimum rectal temperature minus minimum MWST) showed a positive correlation with % fat (r=.600) and a negative correlation with S/V ratio (r=-.881). Decrease in the mean body temperature and heat debt, respectively, showed negative correlations with % fat and positive correlations with S/V ratio.

BACKGROUND/OBJECTIVES: Consumption of pine nut oil (PNO) was shown to reduce weight gain and attenuate hepatic steatosis in mice fed a high-fat diet (HFD). The aim of this study was to examine the effects of PNO on both intestinal and hepatic lipid metabolism in mice fed control or HFD. MATERIALS/METHODS: Five-week-old C57BL/6 mice were fed control diets containing 10% energy fat from either Soybean Oil (SBO) or PNO, or HFD containing 15% energy fat from lard and 30% energy fat from SBO or PNO for 12 weeks. Expression of genes related to intestinal fatty acid (FA) uptake and channeling (Cd36, Fatp4, Acsl5, Acbp), intestinal chylomicron synthesis (Mtp, ApoB48, ApoA4), hepatic lipid uptake and channeling (Lrp1, Fatp5, Acsl1, Acbp), hepatic triacylglycerol (TAG) lipolysis and FA oxidation (Atgl, Cpt1a, Acadl, Ehhadh, Acaa1), as well as very low-density lipoprotein (VLDL) assembly (ApoB100) were determined by real-time PCR. RESULTS: In intestine, significantly lower Cd36 mRNA expression (P<0.05) and a tendency of lower ApoA4 mRNA levels (P = 0.07) was observed in PNO-fed mice, indicating that PNO consumption may decrease intestinal FA uptake and chylomicron assembly. PNO consumption tended to result in higher hepatic mRNA levels of Atgl (P = 0.08) and Cpt1a (P = 0.05). Significantly higher hepatic mRNA levels of Acadl and ApoB100 were detected in mice fed PNO diet (P<0.05). These results suggest that PNO could increase hepatic TAG metabolism; mitochondrial fatty acid oxidation and VLDL assembly. CONCLUSIONS: PNO replacement in the diet might function in prevention of excessive lipid uptake by intestine and improve hepatic lipid metabolism in both control diet and HFD fed mice.

A study was carried out to investigate the effect of palm oil supplementation on the growth, carcass composition and fatty acid distributions of the broilers fed isonitrogenous and isocaloric diets. This study showed that palm oil supplementation increased feed consumption, weight gain and nitrogen intake. Feed conversion improved at higher fat inclusions, but not significant. Male birds consumed significantly more feed than females resulting in significant increase in energy consumption and weight gain. Increaseing fat content in the ME:P constant diet did not produce significant difference in the fat content of the chicken. Fatty acids content of the diet exert varying effects of the composition and distribution of fatty acids in muscles of the chicken. The fatty acids found in larger amount in the breast and thigh muscles were palmitic, oleic and linoleic. The fatty acids of the breast and thigh muscles were found to correspond the fatty acids of the diets. There were no differences in the fatty acids distribution patterns between the sexes.

Background: The effects of diet on epidemiology of prostate cancer are inconclusive. Therefore a hospitalbased, case-control study was conducted in a rural population of Faisalabad, Pakistan, to examine the impact of dietary factors on risk of cancer development. Materials and Methods: This study was based on 102 confirmed cases of prostate cancer and 204 normal controls. Logistic regression was used to estimate odds ratios and 95% confidence intervals for odds ratios to evaluate the relationship between prostate cancer and diet. Results: Consumption of red meat and fat items significantly increased the prostate cancer risk having odds ratios and 95% confidence intervals of 3.41; 1.46-7.96 and 2.45; 1.17-5.15, respectively. On the other hand, more consumption of vegetables, fluid intake and fruit significantly decreased the prostate cancer risk (odd ratios and corresponding 95% confidence intervals of 0.21; 0.10-0.44, 0.10; 0.05- 0.19 and 0.09; 0.03- 0.23, respectively. Conclusions: The present study supports the hypothesis that frequent consumption of red meat and fat items may increase prostate cancer risk while more intake of fruit, vegetables and fluid intake may protect against prostate cancer in the relatively low risk group in rural Pakistan.
