  • In this study, we determined major foods and food groups which contributed to the intake of folate in korean child-bearing women. Folate content of the major foods was also analyzed. A total of 91 healthy women with childbearing potential participated. They were divided into one of three groups by age; A (15∼24 yrs), B(25∼34 yrs) and C (35∼49 yrs). Food consumption data of the subjects were obtained by the 24-hr recall method. The rate of contribution of each food to the total intake of dietary folate was determined. Seventy major foods for folate were selected from the 178 foods they consumed. Two sets of the 70 foods were collected from different markets. After extracting folates from the foods by heating with a HEPES-CHES buffer, the samples were treated with α-amylase, protease and folate intakes was Korean cabbage kimchi followed by laver, soybean sprout, rice, yolmu kimchi, eggs, lettuce, perilla leaves, sea mustard and radish root. Food items that contributed to folate intake were slightly different among the age groups. Although the folate content of Korean cabbage kimchi was 51.6 ㎍/100g, but due to the high amount of intake, it was ranked the first major food prviding folate. High folate foods containing over 100㎍/100g were laver, corn flakes, spinach, mungbean, sesame, quail's eggs, small radish kimchi, kidney beans, leeks and peanuts. However, based on the serving size, spinach, corn flakes, leeks, sweet potato, pepper leaves, quail's eggs, crown daisy, small radish kimchi and perilla leaves contributed above 50㎍ of folate per serving size.

  • Nutrition is one of the factors influencing cognitive functions. But, the role of nutrition on cognitive functions within the elderly is recognized to a lesser degree. The aim of this academic endeavor was to analyze the affiliation between nutritional status and cognitive functions of the elderly in Korea. 316 subjects, of 114 male and 201 female aged above 65 years, were gathered from university hospital clinics, Elderly Welfare Centers, and Health Welfare Centers located in the district of Seoul, Gyeonggi province, and Incheon in Korea. The cognitive function was tested by the Korean-Mini Mental State Examination (K-MMSE) questionnaire. Nutrition intake was assessed by a 24-hour recall, a food frequency questionnaire (FFQ). Nutrition adequacy and quality were assessed by the Nutrition Screening Initiative (NSI) checklist, the nutritional adequacy ratio (NAR), and the mean adequacy ratio (MAR). The elderly with normal cognitive function status displayed significantly higher levels of calcium, riboflavin, thiamin, folate, vitamin C, vitamin E, vitamin B6, phosphorous, potassium, iron, niacin, zinc, animal fat, animal protein, polyunsaturated fatty acids, total protein, vegetable oil, vegetable protein, fiber than levels of the elderly with moderate cognitive impairment. The K-MMSE score positively correlated with of high consumption of pork, white radish, sea mustard, tomato, tangerine, grape, apple, and ice cream, and K-MMSE was negatively associated with high intake of potato, anchovy, fish cake, and mushroom. The findings suggest that nutritional status is affiliated with cognitive function within the elderly of Korea. The consumption of variety of foods and nutrients ensures adequate cognitive function in the Korean elderly.

  • This study was intended to develop traditional Korean soup recipe which can be used for food service and meet consumers' taste with a focus on clear soup such as clear radish soup, sea mustard soup, dried pollack soup, croaker soup, and backbone soup. The developed sample(S1) showed the highest level of overall preference among consumers. There were significant differences in sensory characteristics of the samples especially between S1 and others. The sensory characteristics of each soup showed a slight difference depending on the kind of soup, however, all items had an effect on overall preference. One of the standardized recipe to make broth was presented as follows: The ingredients for broth consists of the shank or brisket of beef(100 g), water(10 cup), spring onion(20 g), onion(30 g), garlic(10 g), salt(1 teaspoonful), and black pepper power(1/10 teaspoonful). 1) The meat part of shank or brisket is prepared. 2) The unfrozen meat is immersed in cold water for 20 min, whereby blood is extracted from the meat. 3) 10 cups of water are poured into the pan and boiled enough. 4) After water has boiled enough, the lump of meat with blood extracted is cut into 2 or 3 pieces and is boiled in the boiling water by high-intensity heat with the pan lid uncovered, and dirty foam is scooped out while boiling. 5) If the broth begins to be extracted, the intensity of heat is lowered for boiling for one hour or so, and then again boiled for 30 min with spring onion, garlic, onion and the like. If the broth is extracted enough, spring onion, garlic, onion, and others are removed from the pan. the broth is seasoned with salt and black pepper powder, and foam is removed by using fine mesh sieve or gauze. Then, 6 cups of clear broth is obtained finally.

  • The number of elderly in care facilities is increasing in parallel with a rapid increase in the elderly population in Korea. We analyzed the meal satisfaction ratings, food preferences, and nutritional intakes of 74 patients aged ≥65 years living in a nursing hospital in Daegu. Food preferences were high for cooked rice, rice gruel, meat soup, soybean paste stew, beef, frozen pollack, squid, egg, spinach, sea mustard, cabbage kimchi, apple, peanut, drinking yogurt, pickled perilla leaves, and salted squid. Preferences for duck (P<0.01) and vegetable (P<0.01) cooking method were significantly different for men and women, and preference for soybean paste stew increased with age (P<0.05). Regarding nutrient intakes, men had higher energy (P<0.01), carbohydrates (P<0.05), and zinc (P<0.05) intakes than women, while women had higher vitamin C (P<0.05) intake than men. Furthermore, energy (P<0.001), carbohydrates (P<0.001), protein (P<0.05), dietary fiber (P<0.01), vitamin B6 (P<0.01), phosphorus (P<0.05), and zinc (P<0.001) intakes significantly decreased with age. Men had a significantly higher nutrient adequacy ratios (NARs) for carbohydrates (P<0.05) and cal- cium (P<0.01) than women, while women had a significantly higher NARs for protein (P<0.05), vitamin A (P<0.01), vitamin C (P<0.05), thiamine (P<0.01), riboflavin (P<0.001), iron (P<0.001), and zinc (P<0.01). Mean adequacy ratios were 0.69 for men and 0.75 for women. In particular, NARs for carbohydrates (P<0.01), vitamin B6 (P<0.01), and calcium (P<0.05) decreased significantly with age. In summary, the study shows that supplementing vitamin C, vitamin B6, calcium, and iron, reducing sodium, and providing meals that reflect preferences will improve the nutritional statuses of elderly residents in a nursing hospital.
