Comparative Evaluation of Dietary Intake Status on Self-selected Diet in Korean Adults by Region Groups

The purpose of this study was to compare the nutritional menu value of self-selected diet in Korean adults residing in different regions. Subjects were recruited and divided into three groups according to the districts where they lived, which included rural district(n=137), coastal district(n=100), and urban district(n=117). Subjects were interviewed using a general questionnaire and 24-hour recall method for dietary intake. The average age of the subjects were 57.5 years for rural district, 57.0 years for coastal district, and 47.9 years for urban district. The contents of energy, calcium, zinc, vitamin B2, and vitamin E in self-selected diet were 76.1%, 60.1%, 73.1%, 68.6%, and 80.4% of RDAs, respectively. Index of nutritional quality(INQ) for calcium and vitamin B2 was below in 1 in region groups. The contents of calcium and vitamin E in self-selected diet of rural and coastal districts were significantly lower than those of urban district. The numbers of food items in diet of rural, coastal, and urban district were 14.6, 15.3, 15.1 for breakfast, 16.5, 11.8, 17.0 for lunch, 14.9, 12.1, 15.1 for dinner, respectively. However, there was no significance in total food intake by regions. The food intakes from cereals, mushrooms, vegetables of rural district, that from fishes of coastal district, and those from sugars, milks, oils of urban district were the highest among three districts. The numbers of dish items in diet of rural, coastal, and urban district were 4.1, 4.4, 4.1 for breakfast, 4.5, 3.7, 4.4 for lunch, 4.0, 3.8, 4.2 for dinner, respectively. Especially, the number of food and dish items in lunch menu of coastal district was the lowest among region groups. According to these results, it could be suggested to add milk and its products in lunch menu of rural and coastal districts and to supplement fish and shellfish like anchovy in diet of rural and urban districts. And it is recommended to increase food and dish items in diets of three region groups.

The Relation between Nutrient Intakes and Blood Parameters of Cardiovascular Function of Female College Students in Chungnam

The purpose of this study was to investigate the relationship between nutrient intakes and blood parameters of cardiovascular function in 40 female college students on self-selected diet in Chungnam. Anthropometric measurements, analysis of dietary intakes and blood composition were conducted. Serum levels of triglyceride, total cholesterol, HDL-cholesterol, LDL-cholesterol, CK-MB, and LDH were measured by biochemical analyzer. The results were summarized as follows. The mean age of the subjects was 22.5+/-7.2 years. The weight, height and BMI were 52.4+/-7.2kg, 161.3+/-5.7cm and 20.2+/-2.4, respectively. Daily energy and lipid intakes were 1634.2+/-437.7kcal and 46.8+/-17.0g. And the ratio of carbohydrate, protein, and lipid to energy intake was 59.2 : 14.5 : 26.3. Serum concentrations appeared to be 61.1+/-24.2mg/dl(triglyceride), 141.2+/-33.0mg/dl(total cholesterol), 64.8+/-20.1mg/dl(HDL-cholesterol), 64.1+/-25.4mg/dl(LDL-cholesterol), 7.2+/-3.2IU/iota (CK-MB), 107.9+/-23.4IU/iota (LDH). In the relation between nutrient intakes and serum parameters, vitamin B1 intake showed positive correlation with triglyceride, HDL-cholesterol, and CK-MB, respectively(p<0.001, p<0.05, p<0.05). Vitamin B2 intake had positive correlation with triglyceride(p<0.05). And vitamin C intake had negative correlation with HDL-cholesterol(p<0.05). From these results, it is suggested that the intakes of micro nutrients such as vitamin B1, vitamin B2, vitamin C have relation with cardiovascular function in female college students. However, further systematic research is needed to investigate the functions of micro nutrients in healthy persons for prevention of chronic diseases.
