  • This study was undertaken to investigate the effect of the levels of dietary Zn and alcohol consumption on lipid metabolism in Sprague-Dawley male rats weighing 80 to 90g for eight weeks. Ninety rats were divided into nine groups according to Zn levels and alcohol consumption such as no alcohol group[low Zn diet group(<1ppm. LZ) control Zn diet group(30ppm. CZ) high Zn diet group(60ppm, HZ)] 10% alcohol consumption group[the same Zn levels as no alcohol group LZLA, CZLA, HZLA] 20% alcohol consumption group[the same Zn levels as no alcohol group, LZHA, CZHA, HZHA] The results obtained were summarized as following : 1) In the serum total cholesterol increased with increasing dietary Zn levels but decreased with alcohol consumption. HDL-cholesterol decreased with alcohol consumption. Triglyce-ride in alcohol group was higher than no alcohol group. In alcohol group triglyceride increased with decreasing dietary Zn levels. 2) In the liver total lipid in alcohol group was higher than no alcohol group HA group showed a significant increase. Triglyceride increased with alcohol consumption. 3) In the serum and liver Zn content increased with increasing dietary Zn levels but decreased with alcohol consumption.

  • The purposes of this research were to investigate in-patients' perception on foodservice quality and to examine factors influencing their meal consumption at hospitals. Three general hospitals with over 400 beds in Seoul and Chon-An agreed to participate in the research. A total of 516 in-patients of the hospitals were surveyed on their meal consumptions, reasons of plate wastes, perceptions of foodservice quality, and demographic information. A response rate was 76% after excluding responses with significant missing data. On average the regular diet patients consumed 72%, 69%, and 68% of rice, soups, and side dishes served, respectively; the therapeutic diet patients consumed less than 70% of the meals they were served. The consumption rates did not differ significantly by diet type, gender, age, and hospitalization period. Among the therapeutic diet patients, those who had nutrition education consumed significantly more rice than the others (p<0.05). The main reasons why the patients did not eat all food served were 'lack of energy' and 'not tasty'. The patients' perception on foodservice quality was low; the therapeutic diet patients perceived more negatively than the regular diet patients in 'keeping hot food hot, cold food cold(p<0.05)', 'maintaining consistency of taste(p<0.01)', and 'providing nutrition information(p<0.01)'. To achieve the goal of the foodservice at hospitals, the dietitians can use the findings of the research in developing and implementing strategies to improve the patients' meal consumption. Recipe standardization, employee training, and production management will be useful for improving food quality and nutrition education on therapeutic diets for the patients will improve their meal consumption at hospitals.

  • Even though coix (Coix lachryma-jobi L. var. ma-yuen) has many physiological effects, since it has been known to cause sterility, farmers avoid using coix bran as a forage for their livestock. Therefore, as the consumption of coix increases, coix bran, which is a by product of pounding process, becomes a serious issue of environmental problem. Present study examined the physiological effects of coix bran in normal and diabetic rats for its possible use as a functional material. The effects of coix bran supplementation on plasma and hepatic lipid profile were evaluated in rats fed one of the following diet for 12 weeks : chow diet ; chow-bran diet (chow diet+25% coix bran), high fat diet and high fat-bran diet (high fat diet+25% coix bran). Additionally, glucose challenge and lipid metabolism in streptozotocin-diabetic rats were also examined. In normal rats, consumption of coix bran remarkably reduced body weight gain in chow or high fat diet fed rats. Additionally, consumption of coix branreduced blood TG, TC and atherogenic index (26%, 24% and 72%, respectively) in chow diet fed rats. Liver TG and cholesterol concentrations were reduced (43% and 49%, respectively) in high fat fed rats by coix bran supplementation. In diabetic rats, fasting blood glucose level was reduced about 25% by coix bran consumption. Also, glucose challenge pattern was improved and resembled normal pattern : it reaches to peak 15~30 minutes after glucose administration and get back to fasting blood glucose level after 90 minutes. Plasma concentrations of TG were elevated in diabetic rats and were reduced to normal level by coix bran supplementation. Liver TG and cholesterol concentrations were also elevated in diabetic rats and reduced to normal level by consumption of coix bran. These results suggest that coix bran may have beneficial effects on blood lipid and glucose level in normal and diabetic rats.

  • Eryngium foetidum Linn. leaves (EF) are widely used in Thailand and many countries throughout Asia as a culinary seasoning and a traditional medicine. However, adverse effect of high dose consumption in long duration has not been evaluated. The aim of this study was to investigate chronic toxicity of EF in mice. Thirty-two ICR male mice were divided into 4 groups of 8 mice each. The mice were fed AIN-76 rodent diet, or AIN-76 rodent diet supplemented with ground freeze-dried EF at 0.8%, 1.6% and 3.2% that is equivalent to approximately 35, 73 and 155 times that of human consumption, respectively, at 97.5 percentile for a period of 24 weeks. At the end of experiment, the mice were euthanized and blood samples were collected for hematological and biochemical evaluations. Necropsy was performed while visceral organs such as lung, liver, kidneys, spleen etc. were collected, weighed and histopathologically examined. Blood urea nitrogen (BUN) results of mice in 1.6% and 3.2% EF diet groups were significantly higher than the BUN of control group. No significant difference was noted in other biochemical and hematological properties between the treatment groups and control; all results were within normal range. Histopathology of almost all visceral organs showed no significant changes. However, tubulonephrosis and chronic interstitial nephritis were observed in the groups treated with 1.6% and 3.2% EF diet. Body weight was reduced significantly at week 12 to week 20 when compared to the control group while relative kidney weights were significantly increased. In conclusion, the consumption of EF in diet at high doses illustrated the adverse effect on some biochemical parameters and histopathology in mice. Our findings suggested that EF daily consumption for 24 weeks, at higher doses than the 0.8% EF diet (35 times of human consumption), might cause adverse effect on kidney function in mice.

  • This study was designed to provide fundamental data on the consumption of fast food for a balanced diet of university students. The effects of personal characteristics and preferences such as gender, major, residing region, living expense, school grade, dieting, physical activity, smoking and alcohol consumption on fast food consumption patterns were analyzed by surveying university students. The analysis showed significant differences (p<0.05) in the consumption of different types of fast food depending on different personal characteristics and preferences as follows : hamburger by major, physical activity and alcohol consumption; chicken by school grade, physical activity and alcohol consumption; spaghetti by gender and smoking. Groups of different majors and school grades showed significant differences (p<0.05) in response to a question "Have you ever eaten fast food for regular meals?". The choice of fast food types based on taste and price appeared to be significantly influenced by majors and gender. Different groups with different majors and dieting experience appeared to think significantly differently about fast food. In response to a question "Has the consumption of fast food changed your diet style" different groups of different majors and physical activities showed significant differences. The analysis of factors affecting fast food choices revealed that fast food is chosen significantly differently depending on gender and majors (p<0.05). The purchase of fast food appeared to be significantly affected by gender, diet, physical activity, experience of fast food and consumption of fast food for regular meals (p<0.05).

  • This study was undertaken to investigate effects of alcohol and fat content in a balanced diet on growth, hepatic function and some biochemical indices of blood in growing rats. Fourty eight male rats of Sprague-Dawley strain weighing about 160g were divided into 4 groups ; high fat diet group, alcohol-adminstered high fat diet group, low fat diet group and alcohol-administered low fat diet group. High and low fat diet supplied 30% and 12%, respectively, of total calorie intake from fat and alcohol-treated groups received water containing 10% ethanol. Diets contained adequate amounts of all nutrients required for rats, including lipotropic agents(choline and methionine) to minimize effects of factors other than alcohol on liver function. Growth rate was lowest in alcohol-administered low-fat diet group, despite that their energy intake was equivalent to the others. For a 3-week study period, 21.86% and 23.61% of total calorie intake were derived from alcohol in alcohol-adminitered high fat diet group and low fat diet group, respectively. There was no influenced on vitamin B$_1$ status by alcohol consumption. Concentration of triglyceride in plasma increased with alcohol comsumption, and the effect was greater after 6 weeks than after 3 weeks of alcohol consumption . Difference of dietary fat content did not affect the level of triglyceride . The levels of total cholesterol and HDL-cholesterol in plasma were not influenced by alcohol consumption. Serum glutamate pyruvate transaminase activity and hepatic mitochondrial respiration rate did not differ between groups. The results indicate that neither moderate alcohol drinking for 6 weeks nor fat content with a balanced diet caused any dramatic change of metabolism and liver function in rats. However they suggest that even moderate alcohol consumption can affect growth of animals dramatically and the effect may be lessened with relatively high fat content in diet.

  • Nutrition counseling and dietary intervention are essential to obesity management because weight reduction is the consequence of negative energy balance. The first step of the nutrition counseling in patients with obesity is thorough evaluation of the nutritional status. During the nutritional evaluation, amount of energy consumption, dietary habits, and medical and socioeconomic factors influencing diets should be evaluated. Diet interventions including low calorie diet, low fat diet, low carbohydrate diet, and high protein diet are all effective in weight reduction as long as decrease in energy consumption is accompanied. Amount of energy restriction and choice of diet interventions should be individualized based the medical condition and characteristics of each patient.

  • Fifteen sheep were used in a trial which compared the feeding value of whole barley gain and cottonseed cake as supplements to a basal diet of leaves of fourwing saltbush (Atriplex canescens). Diet SB contained 700 g (air-dry matter) of saltbush alone, diet SB + BG contained 700 g SB with 400 g whole barley grain and diet SB + CS contained 700 g SB with 400 g cottonseed cake. The digestibility of the dry matter of diets SB (69%) and SB + CS (70%) were lower (p < 0.001) than of diet SB + BG (76%). Sheep offered SB alone daily lost 80g whereas those fed the other diets gained 11 g (SB + CS) or 17 g (SB + BG) per day. Daily water consumption of the sheep offered the three diets was similar (p > 0.05), but their water consumption was higher (p < 0.001) than that of sheep offered daily 700 g wheat straw and 200 g barley grain. The results indicate that, at the levels of feeding used, barley grain and cottonseed cake had similar value as supplements to fourwing saltbush harvested in summer. The addition of the supplement allowed the sheep to gain some live weight. However, the presence of saltbush leaves in the diet resulted in higher water intakes by the sheep.

  • This study was undertaken to investigate the effect of increase in the ratio of zinc to copper and alcohol consumption on serum lipid content in Sprague-Dawley male rats during five weeks. Sixty rats were divided into six groups, CZ < zinc 30ppm diet >, CZA < zinc 30 ppm diet plus alcohol 5% solution >, HZ < zinc 300ppm diet >, HZA < zinc 300ppm diet plus alcohol 5% solution >, SHZ < zinc 600ppm diet >, SHZA < zinc 600 ppm diet plus alcohol 5% solution >. High ratio of zinc to copper groups < HZ, SHZ > were significantly decreased in high-density lipoprotein (p<0.01) and increased in total cholesterol, triglyceride, total lipid in serum(p<0.001, p<0.001, p<0.01). Triglyceride levels of serum in alcohol groups < CZA, HZA, SHZA > were significantly higher (p<0.001) than non-alcohol group < CCZ, HZ, SHZ >. Copper levels of serum were reduced in group high ratio of zinc to copper. These results present that high ratio of zinc to copper increase cholesterol(p<0.001) and alcohol consumption increase triglyceride(p<0.001) in serum. This close association to lipid metabolism in rats draw attention to the potential significance of zinc and alcohol nutriture in relation to cardiovascular disease.

  • The purpose of this study was to evaluate nutrition intake and diet quality according to beverage consumption status in elementary school students (ESS = 317), middle-school students (MSS = 431), and high-school students (HSS = 373). We analyzed data from the combined 2007-2008 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects were divided into two groups, the non-beverage group and the beverage intake group according to beverage intake from drink types (fruit-vegetable drinks, carbonated drinks, and dairy drinks). Intake of dairy drinks was significantly lower in the carbonated drinks intake (CDI) group, compared with the non-CDI group in the MSS group. Intake of vitamin C was significantly higher in the fruit-vegetable drinks intake (FVDI) group, compared with the non-FVDI group. Intake of Ca and P was significantly lower in the CDI group, compared with the non-CDI group. Intake of vitamin B2, Ca, and P was significantly higher in the dairy drinks intake (DDI) group, compared with the non-DDI group. The mean adequacy ratio (MAR) of the FVDI group and the DDI group was significantly higher than those of the non-FVDI and non-DDI group. In diet quality, nutrients less than 1 on the index of nutritional quality (INQ) were significantly higher in the CDI group, compared with the non-CDI group. In conclusion, consumption of carbonated drinks dropped the diet quality however, consumption of fruit-vegetable drinks and dairy drinks improved the diet quality of micronutrients. Therefore, a well-planned diet must be used for replacement of nutrients lost from excessive intake of carbonated beverages during a time in life when growth is especially prominent.
