  • This study was carried out to collect information to establish a framework for meal management and nutritional service for prevention of chronic degenerative disease in the industrial workers. We investigated the health concerned life-style, nutrient intakes, anthropometry and biochemical parameters in the male workers in Korea by work condition. Anthropometric parameters of height, weight, waist, hip and triceps skinfold thickness were measured and biochemical parameters including Urine pH, hemoglobin, blood glucose, total cholesterol, GOT, GPT, $\gamma$-GPT and blood pressure were determined for 101 subjects(50 office workers : 33.9yr, 51 laborers : 34.4yr). To assess the nutrient intakes and diet quality of workers, dietary intake was measured by one day 24-hour recall method. Result of anthropometric parameters of height(p<0.01), weight(p<0.05), hip(p<0.05), TSF(p<0.01) were significantly higher in office workers than in laborers. Biochemical parameters were not significantly difference in both of them. Average daily nutrient intakes of both groups was higher than the Korean RDA and report on 2001 National Health & Nutrition Survey. The calcium(p<0.01), iron(p<0.05), vitamin A(p<0.01), vitamin B1(p<0.01) and niacin(p<0.05) intakes in laborers were significantly higher than in office workers. Nutrition adequacy ratio(NAR), mean adequacy ratio(MAR) and index of nutritional quality(INQ) of laborers were higher than those of office workers. This results indicated that the onset possibility of chronic degenerative disease appeared higher in office workers. Therefore, meal menagement and nutritional service for prevention of chronic degenerative disease of industrial works needs to be more variant guidelines.

  • This study examined the effects of a brown rice vegetarian diet and outdoor walking exercise program on body composition and blood lipid parameters in collegians. The mean age of respondents was 21.8 yrs (males) and 21.7 yrs (females). During the ten-day program, the respondents lived in a dormitory and had three meals. The respondents exercised one hour in the morning (6:20~7:20 am) and attended one and a half hour evening lecture (7:00~8:30 pm) everyday. The brown rice vegetarian diet consisted of brown rice, whole grain bread, beans, fresh vegetables, and fresh fruits contained $2043.2{\pm}112.7$ kcal (97.3% of RNI), 66.7 g protein (133.3% of RNI), 33.6 g dietary fiber (168.2% of RNI), vitamin A (194.2% of RNI), vitamin $B_1$(245.5% of RNI), vitamin $B_2$(225.1% of RNI), niacin (233.7% of RNI), vitamin $B_6$(277.1% of RNI), folic acid (128.4% of RNI), vitamin C (334.6% of RNI), iron (131.9% of RNI), zinc (112.4% of RNI) and calcium (60.3% of RNI). The results showed that there were significant increases in body weight (P<0.05) and BMI (P<0.05) in males and body weight (P<0.05) and lean body mass (P<0.01) in females. In addition, there were significant decreases in total cholesterol (P<0.001), LDL cholesterol (P<0.001), TG (P<0.05), and HDL-cholesterol (P<0.001) in males and total cholesterol (P<0.01) and LDL-cholesterol (P<0.01) in female. The ten day brown rice vegetarian diet rich in fiber and outdoor walking exercise program significantly increased body weight and decreased total cholesterol and LDL-cholesterol in collegians.

  • We investigated diet supplementation with shiitake mushroom fruiting bodies on biochemical and histological changes in hypercholesterolemic rats. Six-wk old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. A diet containing 5% Lentinus edodes fruiting bodies given to hypercholesterolemic rats reduced plasma total cholesterol, triglyceride, low-density lipoprotein (LDL), total lipid, phospholipids, and the LDL/high-density lipoprotein ratio by 34.33, 53.21, 75.00, 34.66, 25.73, and 71.43%, respectively. Feeding mushroom also significantly reduced body weight in hypercholesterolemic rats. However, it had no detrimental effects on plasma albumin, total bilirubin, direct bilirubin, creatinine, blood urea nitrogen, uric acid, glucose, total protein, calcium, sodium, potassium, chloride, inorganic phosphate, magnesium, or enzyme profiles. Feeding mushroom increased total lipid and cholesterol excretion in feces. The plasma lipoprotein fraction, separated by agarose gel electrophoresis, indicated that L. edodes significantly reduced plasma ${\beta}$ and pre-${\beta}$-lipoprotein but increased ${\alpha}$-lipoprotein. A histological study of hepatic cells by conventional hematoxylin-eosin and oil red-O staining showed normal findings for mushroom-fed hypercholesterolemic rats. These results suggest that shiitake mushrooms could be recommended as a natural cholesterol lowering substance in the diet.

  • This study was carried out to investigate the nutritional and physical status of children, aged 11 and 12 years, living in Haenam Koon (living at home) and in Mokpo City (living in an orphan asylum) located in Chonnam during the period of August 2 nd to 9 th in 1984. The mean values of height, chestgirth, arm circumference and head circumference between both groups of living in the rural area and in the city orphan asylum were not statistically different and similar to Korean Growth Standard. Exceptionally, the values of height and weight of male living at home in the rural area were lower than Korean Growth Standard (p<0.01). The weight of male living in the city orphan asylum was higher han that of male living at home in the rural area (p<0.01), and the skin fold thickness of female living at home was higher than that of male living at home (p <0.01). The physical indices of children living in the city orphan asylum were more or less higher than those of living at home in the rural area, but the relative weight of male was only significant (p<0.05). The animal protein intake was $8.4{\sim}8.6%$ of total food intake of living at home in the rural area and 6.2% in living in the city orphan asylum. The intake of legumes of children living in the city orphan asylum was more two times than that of living at home in the rural area, but overall fruit intake of living at home was more about two times than that of living in the city orphan asylum. The average intake of all nutrients except thiamine and niacin was lower than RDA. Especially the calcium intake of children in both groups was the lowest of all nutrients ($28.9{\sim}40.6%$ of RDA). Children living at home in the rural area had significantly higher intake of fat and ascorbic acid than children living in the city orphan asylum (p<0.01).

  • The purpose of this study is to examine the current congregate meal service program for homebound elderly. One hundred three meal service centers in charge of the congregate meal service programs as part of the elderly foodservice program were surveyed for administrative structure, menu management, food purchasing and production management, hygiene, equipment, and facilities. Statistical data analyses were completed using the SAS 8.1 program for descriptive analysis and ANOVA. The meal cost of 54.4% of the congregate meal service centers ranged from ₩l,500 to ₩l,999 per meal. According to the menu analysis, all nutrients except calcium and Vitamin B2 were at levels of more than 33% of the Recommended Dietary Allowances for Koreans. A total of 81.5% of the centers were operated without the services of a dietitian, and food purchasing, menu planning and other foodservice management processes were handled by non-professionals, such as volunteers, cooks or social workers. Although 88.3% of the centers required a therapeutic diet menu for the health of the elderly, most directors (77.6%) replied that in their current status they could not afford to serve therapeutic diets. These results suggest that financial and systematic supports by government is very necessary. Fifty-five percent of the centers never used standard recipes. For determining portion sizes, 93.2% of the congregate meal service centers depended on the personal experience of the personnel. Finally, the current congregate meal services for the homebound elderly were not operated systematically. To improve the elderly food service program, it is strong1y recommended that it be managed by Professionals.

  • The purpose of this study was to investigate school dietitians' perception on nutrition labelling of processed and packaged foods in the Incheon area. This study was carried out through a self-administered questionnaire and the subjects were 203 school dietitians. The results were summarized as follows. Most of the subjects checked nutrition labeling of processed and packaged foods when they purchased these foods for school lunch. However, the main reason for their checking nutrition labeling of processed and packaged foods was not for nutrition but for food safety. There were significant differences in the subjects' understanding and trust on nutrition labeling of processed and packaged foods by employment school. The scores of the subjects' satisfaction, understanding and trust on nutrition labeling of processed and packaged foods were not high. There were significant differences in the subjects' perception and concern about content information on nutrition labeling of domestic processed and packaged foods by employment school. Most of the subjects answered that it is almost necessary or very necessary to implement nutrition labelling of processed and packaged foods. Also their most preferred method of nutrition labelling was to label nutrient content. As the most important nutrient and functional component necessary for nutrition labelling, they answered energy, mineral such as calcium and iron, protein, total fat, cholesterol, vitamin, sodium and dietary fiber in order. As the major prerequisite task for the implementation of nutrition labelling, they answered formulation of nutrition labelling-related rules, and education and motivation for consumer, Therefore, it is necessary to activate the mandatory nutrition labelling of the processed and packaged foods and to prepare its consumer education program for school dietitian.

  • This study was conducted to compare the nutrient intake, physical characteristics, and health status according to daily fruits and vegetables intake of adolescents using the Korean national health and nutrition examination survey for the sixth period (2013~2015). Subjects were 1,096 adolescents aged 13~18 years. The average daily intake of fruits and vegetables was $518.49{\pm}4.94g$. The two groups (insufficient, sufficient) were divided by fruits and vegetables intake (<500 g/day, ${\geq}500g/day$) and the ratio of the insufficient group was 75.9% while that of the adequate group was 24.1%. The mean of intake of energy, calcium, phosphorus, sodium, potassium, iron, thiamin, niacin, vitamin C and dietary fiber differed significantly between the insufficient and sufficient groups (P<0.01, P<0.001). However, there was no significant difference in physical characteristics between groups. The self-perceived health status was better in the sufficient group (P<0.05), while the insufficient group was aware of more stress in their daily life (P<0.05). The serum triglyceride was significantly higher in the sufficient group (P<0.05), while the total cholesterol was lower (P<0.05). As the characteristics of fruits and vegetables are different, it will be necessary to determine standards for consumption of each type. It is also necessary to consider whether a fruits and vegetables intake of 500 g would be a reasonable standard for adolescents. Nevertheless, the results of this study indicate efforts to increase fruits and vegetables intake by young people are necessary.

  • Safflower (Carthamus tinctorius L.) seeds have long been clinically used in Korea to promote bone formation and prevent osteoporosis. In addition, the safflower buds (SB) were found to have more useful functional ingredients than safflower seed. Thus, we investigated the preventive effects of SB diet in ovariectomized (OVX) rats. The rats were divided into five groups; sham operated group, OVX alone group, OVX plus 17β-estradiol (E2 10 μg/kg, i.p.) and OVX plus SB diet feeding group (0.3% or 1%). Feeding of SB diet (0.3% or 3%) to OVX rats markedly increased trabecular formation in femur compared to OVX rats. Feeding of SB diet (0.3% or 3%) to OVX rats also decreased TRAP activity compared to OVX rats. These results suggest that SB diets have bone sparing effects by the decrease of osteoclast activity. We also observed that OVX rats fed with SB diet (0.3% or 3%) exhibited the decrease of calcium and phosphorus in serum compared to OVX-induced rats. Therefore, SB may be beneficial for the patients of osteoporosis, especially in postmenopausal women.
