  • The purpose of this study was to estimate beverage consumption frequency and determine related problems of elementary school students in Chungnam. The survey was conducted with 488 students(boys=230, girls=258) using a questionnaire. The average age of the students was 10.1 years old, thir average height and weight were 145.1 cm and 39.5 kg, respectively and the obesity index was -1.3%. The frequencies for breakfast, lunch and dinner were 5.8 times/week, 6.7 times/week and 6.4 times/week, respectively. Regarding the frequency of snacks, high response rates for 'once/day'(38.3%) and 'none' (30.5%) were observed. Nutrition label on beverages were identified rarely(39.1%), nearly never(19.7%), and never(12.9%). The choice factors in selecting beverage were taste, nutrition, and price. For the type of snack most often consumed, fruit or juice was 25.8%, snack items were 25.2%, bread was 24.8%, dairy products were 7.6%, beverages were 7.0%, noddles were 6.2%, and rice cakes were 3.5%. The kinds of favorite beverages were carbonated drinks(30.3%), functional drinks (24.4%) and milk and yoghurt(23.8%), and main reason for the choice of beverage was "it tastes good". For the point of time that students wanted to drink a beverage, "when I feel thirsty" appeared most often for dairy products and beverages and the next most frequent answer was "after exercise". Therefore it may be necessary to administer systematic nutritional education on perception on nutrition fact label of beverage. And it is thought that plan for proper beverage consumption in elementary school students may be established.

  • This study was an investigation of nutrient intake and food habit of college students in Taegu. A total of 200 apparently healthy college students living in Taegu were selected for the study. The 24-hour recall were obtained from subjects. The following anthropometric measurements were made on all participants: weight, height, waist and hip circumferences, and bioimpedence. Dietary habits and energy expenditure were examined through questionnaires. Among the subjects 8.3% were obese and 17.7% were underweight in male and 38.8%, respectively. The average intake of nutrients and energy were below the RDA in male(except protein, vitamin C and phosphate) and female(except vitamin C and phosphate), whereas phosphorus intakes well exceed the RDAs for both groups. Lowest mean intake as percentile of RDA were calcium and riboflavin in male, and calcium and iron in female. The mean adequacy ratio(MAR), an index of overall dietary quality was 0.735 for males and 0.730 for females. The index of nutritional quality (INQ) were under 1.0 for vitamin A(0.91), B2(0.628), Ca(0.074), Fe(0.845) in male students and vitamin B2(0.752), Ca(0.649), Fe(0.594) in female students. The alcohol consumption level was negatively correlated (p<.05)with thiamin, ascorbic acid, carbohydrate, and energy consumption in male students. Also the alcohol consumption was negatively correlated (p<.05) with milk consumption in male students. Thus, unfavorable nutritional patterns of alcohol drinkers put them at double jeopardy regarding micronutrient intake and bone health. In conclusion, this study indicates that nutrient intake in the college student in Taegu is considerably lower than RDA. Another important finding of this study is that an unacceptable calcium and iron status was prevalent in a high percentage of subjects in the college student.

  • Even though the anticarcinogenic effect of dietary factors especially beta - carotene has been reported by various investigators, the mechanism of the action of ${\beta}-carotene$ has not yet been identified. We carried out the present study to determine the possibilities of relative cancer risk related to dietary intake of vitamin A ( both ${\beta}-carotene$ and retinol ) and blood levels of vitamin A among Koreans. The subjects were divided into two groups; cancer patients and controls. Blood levels for ${\beta}-carotene$ and retinol were analyzed by alumina column chromatography and colorimetry. Dietary intake was examined by food profile and convenient method for evaluating nutritional status through recalling 10 years of food habits. The results obtained are as follows : 1 ) Calorie, protein, fat, and carbohydrate intakes of cancer patient were lower than those of control. Calorie and carbohydrate intakes showed no significant difference but protein and fat intakes were significantly lower in cancer patients. According to cancer sites, in stomach cancer only fat intake was significantly lower than that of control. In lung and larynx cancer calorie, protein, fat and carbohydrate intakes showed similar trend as in control. 2 ) Vitamin A intake of cancer patient was significantly lower than that of control. It was estimated that 83.6% of total Vitamin A intake were provided by ${\beta}-carotene$ for control and cancer patient respectively. 3 ) The mean intake of dietary ${\beta}-carotene$ in cancer patient was significantly lower than that in control ( $7002\;\mu}g/day$ versus $10326\;{\mu}g/day$ ) According to cancer sites in mean intake of dietary ${\beta}-carotene$ was significantly lower in all but stomach cancer compared with that of control. Lung and larynx cancer showed lowest ${\beta}-carotene$ intake with mean value of $5855{\mu}g/day$ and $5492{\mu}g/day$ respectively. 4 ) The mean intake of dietary retinol in cancer patient was significantly lower than that in control ( $245{\mu}g/day$ versus $338{\mu}g/day$ ), but the difference was not significant. 5 ) The relative risk of all cancers in the first (lowest) to the forth quartile level of ${\beta}-carotene$ consumption such as $0-5999{\mu}g/day$. $6000-8999{\mu}g/day$, $9000-11999{\mu}g/day$/ day and $12000-20000{\mu}g/day$ was 85 : 1.7 : 20 : 1.0. The relative risk of all cancers in the first (lowest) to the forth quartile level of retinol consumption, such as $0-299{\mu}g/day$, $300-599{\mu}g/day$, 600-899${\mu}g/day$, and $900-1200{\mu}g/day$, was 1.14 : 067 : 0.21 : 1.0. 6 ) The various food group consumption of cancer patient were significantly lower than those of control in green leafy vegetables, fruits, sea weeds, milk and cheese and eggs. But the Kimchie consumption in cancer patient was three fold higher than that of control ( $1840\;{\mu}g/day$ versus $562\;{\mu}g/day$ ) and in the stomach cancer, Kimchie consumption was the highest, ( $1890\;{\mu}g/day$) According to cancer sites, the consumption of green leafy vegetables was significantly lower in all but stomach cancer compared to control and other vegetables showed no difference between two. In lung and larynx cancer, green leafy vegetables consumption was lowest ( $6094{\mu}g/day$ $5921{\mu}g/day$) and milk and cheese consumption was also( $5\;{\mu}g/day$ and $11{\mu}g/day$) 7 ) The recovery of ${\beta}-carotene$ from human serum by alumina column chromatography was $94.4{\pm}2.3%$. 8 ) Cancer patients showed significantly lower serum retinol ($56.4{\pm}18.1\:{\mu}g/100ml$ versus $72.2{\pm}21.8\:{\mu}g/100ml$) and ${\beta}-carotene$ ($48.9{\pm}33.8\:{\mu}g/100ml$ versus $72.2{\pm}42.6\:{\mu}g/100ml$) concentrations than in controls. 9 ) But breast cancer patients were not significantly different from controls in their serum retinol and ${\beta}-carotene$ concentrations.

  • Background: The aim of this study was to investigate demographic features, dietary habits, and some possible risk factors for being susceptible to breast cancer in Iranian women. Materials and Methods: A study of dietary habits and breast cancer was conducted among 53 Iranian women with histological confirmed disease and 40 matched controls. A dietary habits questionnaire was used to evaluate the pattern of selected food intakes. The risk of cancer was analyzed after adjustment for confounding factors. Age, weight, body mass index (BMI), waist circumference, educational status, parity, lactation, marital status, menopause, history of estrogen therapy, and family history of breast disease or cancer were assessed among participants. Special attention was given to the relationship between consumption of high fat meat, milk, yogurt and cheese as well use of frying oils for frying foods, use of olive/liquid oils for cooking, removing fat from meat and poultry, removing chicken skin and not use of mayonnaise as salad dressing and the risk of breast cancer. Moreover, salad, vegetable and fruit consumption, and eating outdoors owere investigated. Results: Our results revealed significant lower education and higher BMI and waist circumference levels in patients with breast cancer. There was significantly increased breast cancer risk in overweight women in comparison with normal weight (OR=2.91, 95%CI 1.24 to 6.82). High intake of fat dairy products including milk and cheese was found to be a statistically significant factor for increasing breast cancer risk in models adjusting for age, BMI and education. Use of olive/liquid oils for cooking and avoidance of mayonnaise as salad dressing are related to lower risk of breast cancer. The frequency of vegetable and fruit consumption was significantly lower in patients with breast cancer compared to healthy women. Conclusions: Dietary habits might be risk factors for breast cancer among Iranian women. Adoption of a prudent diet could be an appropriate strategy for preventing breast cancer.

  • Background: Several studies have pointed to roles of dietary and food groups in the pathogenesis of breast cancer, but information on dietary patterns among women with breast cancer and their healthy counterparts in Iran is limited. Therefore the present investigation was conducted in Guilan province in 2014-2015. Materials and Methods: In a case-control study, 450 women with breast cancer and one of their relatives (third-rank) were investigated. At first the phone numbers of patients in Razi Hospital in radiotherapy and chemotherapy and oncology centers of Guilan were taken. Data were collected through telephone interviews by the researcher. The questionnaire had two parts comprising demographic clinical and food frequency data including a list of 40 food items. To analyze the variables, Chi-square test and univariate logistic regression models were used. Results: In each group, 225 subjects were investigated. The majority of samples in both groups of experiment and control were consumed than two glasses of milk and dairy products per day. Regarding consumption of meat and its products, 56% of the cancer group had more than three servings per day while 26.7% of the control group had less than 2 servings per day. The majority of subjects had less than six servings of cereal per day. Some 54. 7 % of the cancer and 62.2 % of the control group consumed less than two servings of fruit per day. Consumption of vegetables in experimental and control groups were 52.9% and 76.9% respectively, more than five servings per day. There was a meaningful difference between two groups regarding the consumption of milk and dairy items (OR=0.6,95%CI= 0.4-0.9), meat and its products (OR=0.49,95%CI=0.3-0.7), bread and cereals (OR=0.4,95%CI=0.2-0.8), vegetables (OR=0.5,95%CI= 0.3-0.9). (P-value<0.05). Conclusions: The results of this study emphasize the importance of informing women, particularly those at higher risk of breast cancer, in relation to dietary factors.

  • This study was performed to investigate the dietary habits, body satisfaction and nutritional knowledge according to body image of middle school girl students (n = 284). The subjects were classified as lean, normal and fat groups according to body image. The weight, body mass index (BMI) and the score of body image were significantly higher in the students who recognized their body image as 'fat'. The satisfaction of present body image was significantly lower in students who recognized their body image as 'lean'. The interest in weight control and experience of weight control were significantly higher in students who recognized their body image as 'fat'. The necessity of nutrition education was higher in all groups (lean 67.2%, normal 59.0% and fat 52.8%). The products used to feel sweetened were sweetened ice (68.7%), processed milk (68.3%), confectionery (62.3%), carbonated beverage (55.3%), fermented milk (38.0%) and none (6.0%). The frequency of consumption of fruit juices and fried food was significantly higher in 'normal' compared to 'fat'. There was no significant difference in the frequency of consumption of snack and nutritional knowledge among the three groups. In the multiple regression analysis, the score of body image was negatively associated with the frequency of snack consumption in the 'lean'. The score of body image was positively associated with identification of nutrition labels and an interest in weight control but was negatively associated with satisfaction of present body image in the 'fat'. Based on these results, we conclude that, the middle school girl students need correct recognition of body image and continuous and practical nutrition education in order to maintain healthy dietary habits.

  • Food consumption pattern between Korea and Japan were compared on the basis of the data from the National Nutrition survey which has been carried out annually in Korea (1969-1988) and in Japan (1950-1988) for the guide of the future food and nutrition policy. Total food intake has been decreased in Japan since 1973. In spite of fluctation of total food intake, there was an increase of food consumption in Korea. The intake of animal food has been increased, while that of vegetable food decreased, in both countries. Proportion of the total food intake from animal sources of Japanese in 1988, 25.3%, was greater than that of Koreans, 20%. The intakes of cereal and grain products have been decreased in both countries, but the amount of these food groups consumed by Koreans was 70 to 80g more than that by Japanese in 1988. When the animal food intake was compared, intakes of meats, fishes, shellfish and eggs have been increased considerably in Korea. Intakes of milk and milk products and meat have been increased, while those of fishes, shellfishes and eggs kept an even level since 1975, in Japan. According to changes of the national standards of height and weight in both countries, the average height has been increased greatly from 1970 to 1980 in Korea, and the tendency was the same for the average weight.

  • Background: Endemic circulation of human-specific hepatitis E virus (HEV) genotypes 1 and 2 may occult the importance of sporadic zoonotic HEV transmissions in Africa. Increasing numbers of studies reporting anti-HEV antibodies in cattle and the discovery of infectious HEV in cow milk has raised public health concern, but cattle exposure has seldom been investigated in Africa. Objectives: This study aimed at investigating the role of cows in the epidemiology of HEV in Burkina Faso and farmers habits in terms of dairy product consumption as a prerequisite to estimate the risk of transmission to humans. Methods: Sera from 475 cattle and 192 pigs were screened for the presence of anti-HEV antibodies while HEV RNA in swine stools was detected by reverse transcription polymerase chain reaction. Data on mixed farming, dairy product consumption and selling habits were gathered through questionnaires. Results: The overall seroprevalence in cattle was 5.1% and herd seroprevalence reached 32.4% (11/34). Herd seropositivity was not associated with husbandry practice or presence of rabbits on the farms. However, herd seropositivity was associated with on-site presence of pigs, 80.7% of which had anti-HEV antibodies. The majority of farmers reported to preferentially consume raw milk based dairy products. Conclusions: Concomitant presence of pigs on cattle farms constitutes a risk factor for HEV exposure of cattle. However, the risk of HEV infections associated with raw cow dairy product consumption is currently considered as low.

  • The internal and external outputs of the agricultural sub-systems of mixed livestock-crop farms in Pabna Bangladesh were analysed, to clarify the multiple functions of cattle in farm systems. Production systems with grazing areas were relatively more productive than those with no grazing. There was a tremendous variation in farm income, largely because of land area. An increase of one ha in land area was estimated to boost farm income by about 50%. Number of cattle, cattle off-take percentage and milk off-take per average cow related positively to farm income. As land area decreased the relative importance of cattle production increased. Crops were dominant in producing food for home consumption. Cattle contributed only 5-6 per cent to home consumption. Cattle supplied a significant cash income: 45 per cent in the villages with grazing areas and 57 per cent in the other villages. In future, the cash output from cattle will decline and emphasis will shift to the role of cattle in supporting crop production. Any research or development strategy for livestock needs to focus first on the importance of the complex relation between livestock and crops.

  • There is a trend that the total number of cancer cases is steadily increasing as the population grows. It has been estimated that 85% of the cancer rate in the U.S. is attributed to environmental factors. Among the environmental factors, diet and nutrition appear to be related to the largest number of human cancers. Diet and nutrition might be related to cancer by several mechanisms. Food may contain a direct carcinogen or precursors that become carcinogens by spontanous reactions, or by host metabolism, or through the actions of microbial flora. Chemicals that cause cancers generally have reactive electrophilic centers which can combine with electron-rich atoms in nucleic acids and cause cancers by changing the genetic activity of the cells. A variety of factors in foods might be involved in the etiology of carcinogenesis. Chemicals in food that cause cancers include carcinogens of plants and animal origin and also those in drinking water. Other then these, fungal metabolites alcohol, asbestos, heavy metals, pesticides, and food additives might be included as food carcinogenesis. The method of cooking foods also might contribute to carcinogenesis. Some chemicals in foods act as promoters in carcinogenesis. Prevention of cancers by dietary practises have received much interest. Consumption of certain vegetables or cellulose can reduce carcinogenic activity of several compounds. A variety of antioxidants or micronutrients may be effective anticarciongens. Glutathione in the soluble fraction of the cells, is a major defense against oxidative and alkylating carcinogens. Recently anticarcinogenic activity of chlorophyll was demonstrated. Daily consumption of milk appears to effectively reduce stomach cancer.
