The purpose of this study was to assess the frequently consumed dish consumption frequencies of continuous ambulatory peritoneal dialysis(CAPD) patients with osteopenia and develop recipes to improve bone mineral density of CAPD. The subjects were 96 CAPD patients with osteopenia(male 39, female 57) (osteopenia group) and 45 CAPD patients with normal BMD(male 24, female 21), matched with key variables(normal group). Fifty dishes(foods) that most frequently consumed were determined and food consumption frequency for each dish(food) for two groups were compared. Osteopenia group showed lower consumption frequency for ice-cream but higher frequency in apple. Of the 50 most frequently consumed dishes(foods), 20 dishes assessed as safe and recommendable for CAPD patients with osteopenia based on the contents of protein and mineral were selected : white boiled rice, white gruel, beef soup, steamed cabbage, roasted dried laver, fried egg, roasted bean-curd, cooked and seasoned bean sprouts, corn-starch jelly, cheese, ice-cream, orange juice, apple, grape, peach, peanut, raw lettuce, raw cucumber, and injulmi rice cake. wenty eight new dishes with modified recipes were developed for CAPD patients. Protein and mineral contents were analyzed for frequently consumed 17 dishes, assessed as modification of recipes are needed. The recipes were modified to decrease P, Na and K contents and to increase protein and Ca contents. Twenty dishes(foods) selected as having reasonable protein and mineral contents ratio or 28 newly developed dishes modified with protein and mineral contents or ratio would be helpful for nutrition education or counseling for CAPD patients with osteopenia. Dishes(foods) suggested in this study would also be useful for all CAPD patients for preventing osteoporosis.

The surveys of food intakes were carried out on 49 healthy infants aged 4-9 months at the first interview and repeated 3 more times at the interval of 2 months by using food diary recorded by their mothers. Of the subjects 12 were breast-fed, 28, formula-fed, and 9, mixed type-fed. Foods introduced first as the weaning food were commercial weaning foods, fruit juices, yoghurt, egg and rice. Supplemental food was introduced at the age of 4 months in 57% of the infants, but it amounted to a significant proportion of overall food consumption from the age of 6 months. The levels of nutrients except energy, iron and niacin were similar or in excess of RDA, and breast-fed infants tended to have lower intakes of energy and protein compared to infants formula-fed or mixed type-fed. Average intakes of vitamin A, vitamin B1, vitamin B2, vitamin C and calcium were above RDA, but iron intake did not meet RDA of infants of all ages. In conclusion, the average status of nutrient intakes of infants was fairly good, however, food consumption besides milk was less in breast-fed infants than in formula-fed infants, and iron status seemed to be poor, Although it is well-known that breast-milk compared to formulas is more beneficial for infants, mothers feeding breast-milk to their infants should be educated for the importance of supplemental food and its practice to support good nutrition.

The purpose of this study were to analyze the consumption patterns of animal foods during the sixteenth century through Shamirok. There were eleven animal foods : beef, pork, chicken, pheasant, deer, roe, lamb, bear, fox, sparrow, and horse. The most frequently consumed were in the order of pheasant, doe, and chicken. There were 44 fish consumed, including flatfish, hairtail, mackerel, flounder, kumlin fish, bass, null fish, codfish, and red snapper, as well as four mollusks and six shellfish. Eggs and fish egg were also consumed. These foods were cooked as Tang(湯), Gui(灸), Po(脯), Hoe(膾), and Sookyook(熟肉), or processed after being dried or salted. The animal foods were mostly consumed as Po and Tang in daily eating and for formal dishes. Fish were mostly consumed as Jockgal or Shikhae. The foods were primarily acquired by donation from local officials or relatives ; secondly by independent poultry farming, fishing, or hunting, along with the production of grain and thirdly through barter with rice and textiles. Food were sometimes traded for profit, but such acts of trading while living ; as wartime refugees was a meager means for living.

Objectives: This study was conducted to investigate the vitamin D status and to determine the association between serum 25-hydroxyvitamin D [25(OH)D] concentrations and consumption frequencies of vitamin D rich foods in Korean adults and older adults. Methods: Subjects were 10,374 adults and 2,792 older adults participating in the 2008-2009 Korea National Health and Nutrition Examination Survey (KNHANES). Consumption frequencies of vitamin D rich foods were estimated by using a qualitative food frequency questionnaire (FFQ). Eleven food items such as beef, egg, mackerel, tuna, yellow corvina, pollack, anchovy, mushroom, milk, yogurt, and ice cream were selected as vitamin D rich foods based on previous research. Results: The proportions of deficiency (< 12 ng/mL), inadequacy (12-20 ng/mL) and sufficiency (${\geq}20ng/mL$) of serum 25(OH)D concentrations from June to November and December to May in adults were 8.8%, 42.3%, 48.8%, and 28.2%, 52.8%, 19.1%, respectively. The proportions of deficiency, inadequacy and sufficiency of serum 25(OH)D concentrations from June to November and December to May in older adults were 10.1%, 32.4%, 57.5%, and 24.1%, 45.4%, 30.5%, respectively. The mean serum 25(OH)D concentrations in adults were positively related to the consumption frequencies of mackerel, anchovy, all fish, milk and milk dairy products. The mean serum 25(OH)D concentrations in older adults were positively related to the consumption frequencies of yellow corvina and negatively related to the consumption frequencies of ice cream. Conclusions: Our results suggest that Korean adults were more deficient in serum 25(OH)D concentrations than older adults. The consumption of vitamin D rich foods may affect vitamin D status in Korean adults. Further studies are required to confirm these findings.

Rhinitis and sinusitis are among the most common medical conditions in Korea, as well as Western societies. Environmental factors may influence both rhinitis and sinusitis; however, the role of dietary factors in rhinitis and sinusitis is not clear. The present study aims to compare the dietary habit, food consumption frequency, and food preference of elementary school students with or without rhinitis and sinusitis. The demand of their parents for an education program for the dietary prevention against rhinitis and sinusitis was also examined. The survey was conducted with a total of 200 subjects recruited from two elementary schools located in Gyeonggi area of Korea. The subjects consisted of 101 students with rhinitis and/or sinusitis (RS group) and 99 without rhinitis and sinusitis (control group). The students of the RS group were more likely to have habits of eating-out and street food use, to consume bean, peanut, walnut, almond, yogurt, egg, snack, and French fries frequently, and to prefer the types of foods prepared by stir-frying and deep-frying than the control group. The parents who recognized 'school nutrition teachers or food/nutrition-majored specialists' as the most appropriate educator for the dietary education program in the RS group (48.5% of their parents) were less than those in the control group (67.7% of their parents). The present study suggest that students with rhinitis and/or sinusitis may be different from those without the disease(s) in their dietary habit, frequently consumed foods, and preferred type of foods. More epidemiological, intervention, and laboratory studies are needed in order to elucidate the role of dietary factors in the development and prevention of rhinitis and sinusitis, which will have a significant implication to public health.

Highly pathogenic avian influenza (HPAI) occurred in the breeder duck farms in Jeonbuk of in Korea on January to February 2014. Clinically, the most ducks showed various signs from depression, dropped egg production and feed consumption to even, death. The most commonly gross changes were hepatomegaly, splenomegaly, petechial and ecchymotic hemorrhage on the liver surface, a white stripe on the cardiac muscle, multifocal hemorrhagic foci in pancreas, and severely hemorrhagic embryos. The most significant signs of H5N8 virus was supposed to specific on ducks. The viral antigen was mainly detected in the endothelium of blood vessels of various organs and tissues, peripheral nerves, and neuronal cells. Based on the above results, we identified that HPAI H5N8 induced systemic infection in the adult breeder ducks.
