BACKGROUND/OBJECTIVES: The nutritional quality of lunches is an important factor related to workers' health. This study examined the nutritional quality of Korean workers' lunches with a focus on comparing institutional and commercial lunches. SUBJECTS/METHODS: The data from a 1-day, 24-hour dietary recall from the $5^{th}$ Korea National Health and Nutrition Examination Survey (2010-2012) were analyzed. A total of 2,192 subjects aged 19 to 64 years, who had consumed lunches served by institutional or commercial food service vendors, were included for analysis. The nutritional quality of the lunches of the institutional lunch group (n=626) and the commercial lunch group (n=1,566) was compared in terms of the number of servings, food groups, nutrient intake, Nutrient Adequacy Ratio (NAR), and Mean Adequacy Ratio (MAR). RESULTS: The NAR and MAR were significantly higher in the institutional lunches than in the commercial lunches, but more than half of workers in both groups obtained over 65% of their energy from carbohydrate. The average sodium intake from the lunches exceeded the daily intake goal (2,000 mg) in both groups. More than half of workers in both groups presented less than one-third of their respective recommended daily intake of riboflavin and calcium. With the exception of riboflavin, the nutrient intake from lunches accounted for more than 35% of the daily nutrient intake. CONCLUSIONS: The overall nutritional quality of institutional lunches was higher than that of commercial lunches. However, institutional lunches had room for improvement in terms of nutritional quality.

This study investigated the nutrition knowledge, dietary habits, and food intake frequency according to hospitalization after breast cancer surgery and experience of breast cancer among female adults residing in the Bucheon area. Subjects were 52 female breast cancer survivors 27 in the hospitalization group (HG) and 25 in the non-hospitalization group (non-HG)] and 52 controls. Data included the results of self-administered questionnaires, as well as anthropometric data and blood biochemical values of breast cancer survivors collected from electronic medical records. Statistical analysis was performed using SPSS 20.0 program. Nutrition knowledge and dietary habits revealed no significant differences between HG and non-HG, but intake frequency of root and tuber crops and kimchi was significantly higher in the HG group than the non-HG group (p<0.05). According to experience of breast cancer, total scores of nutrition knowledge among survivors (8.2) were significantly higher than those of the control group (6.3) (p<0.001). Fish and shellfish and fruit intake frequencies were significantly higher in the survivors group, whereas intake frequency of fast food, convenience food, and alcohol was significantly lower compared to the control group. Overall, these findings indicate it is necessary to develop and spread nutrition education guidelines to prevent the occurrence and recurrence of breast cancer.

This study was conducted to investigate sodium and potassium balances, as well as correlations among the relating factors in adult males and females. We collected blood, urine and feces samples as well as a dietary intake survey from 50 subjects. Then, we analyzed the sodium and potassium contents in blood, urine and feces, and evaluated their state of balance. The average ages of the study targets were 24.7 years old for males and 22.8 years old for females. The daily energy intake by the males was 1733.4 kcal and by the females was 1570.3 kcal. Sodium intakes were 138.3 mEq and 127.5 mEq for males and females, respectively. Potassium intakes were 43.1 mEq and 49.3 mEq, respectively. The daily excretions of sodium through urine were 136.6 mEq by males and 97.0 mEq by females and the excretions through feces were 2.2 mEq and 2.0 mEq, respectively. The daily excretions of potassium through urine were 20.2 mEq and 16.5 mEq by males and females respectively, and the excretions through feces were 7.7 mEq and 7.5 mEq male to female. The retention rates of sodium were 11.7% and 14.1% male to female, respectively, and the apparent absorption rates were 98.5% and 97.8%. Additionally, the retention rates of potassium were 32.9% and 39.8% and the apparent absorptions were 81.9% and 81.3%, both male and female. It was noted that, overall, the sodium intake of adult males and females is still higher than the recommended daily sodium intake, while the potassium intakes and excretions were found to be lower. Based on the results of this study, nutritional guidance and education is recommended to encourage decreased sodium intake and increased potassium intake, according to recommended standards.

The purpose of this study was to investigate whether the health status as determined by a self-assessment checklist was related to the nutritional status of elderly Korean women. We interviewed 59 female subjects living in the Daegu area aged over 55 years. Information on their dietary intake on two consecutive days was collected by the 24-hour Recall Method. Their body compositions were measured using a Bio-electrical Impedence Fatness Analyzer. Their zinc status was evaluated according to their dietary zinc intake and urinary zinc excretion in urine samples collected for 24 hours. Their heath status was determined by a NSI Checklist. While 50.9% of the total subjects belonged to a moderate nutritional risk group,23.7% of the subjects were at a high nutritional risk. It appeared that only 25.4% of the subjects were evaluated as being healthy. Therefore, the overall nutritional health status of the elderly females belonged to the moderate nutritional risk group. Except for vitamin C, the average daily nutrient intake of the subjects was below the level of the recommended dietary allowances (RDA) for Koreans. The lower the nutritional health score, the better was their dietary intake of energy (p<.05), protein (p<.001), and zinc (p<.01). A positive relationship between their nutritional health score and body fat ratio was also observed (p<.05). Therefore, we suggest that the NSI Checklist could be used as a practical screening tool at the beginning of nutritional surveillance of the elderly in the community.

The purpose of this study was to examine bowel habits, dietary habits, and nutrient intake of constipated adults, and the effects of prune products on relieving constipation symptoms. Fifty one adults with self-reported constipation (mean age 23 years, range 19-41 years, 10 males and 41 females) participated in this study. After a baseline survey on bowel habits and dietuy habits, participants were asked to consume at least 50 g of prune and 200 ml of prune juice per day during a 4-week period in addition to usual diet. Nutrient intake was estimated by a 24 hour recall at the baseline and once every week by diet records during the intervention. Data were analyzed after classifying the subjects into mild constipation group and severe constipation group by the severity of the symptoms. During the intervention, the subjects with mild constipation consumed 56 g of prunes (about 5.6 fruits) and 200 ml of prune juice, and the subjects with severe constipation consumed 59 g of prunes (about 5.9 fruits) and 207 ml of prune juice. Average intakes of energy, dietary fiber and water of the subjects in the mild constipation and severe constipation group increased during the intervention compared to the baseline. Average dietary fiber intake of the mild constipation and severe constipation groups significantly increased from 12.5 g and 11.6 g at the baseline to 18.5 g and 16.8 g after consuming prune products, respectively. These changes were accompanied by an increase in the number of bowel movements, a decrease of defecation time, a change to a softer stool consistency, and a decrease of abdominal pain during defecation. Seventy two subjects answered that prune products were effective to improve their overall constipation symptoms. Our data show that supplementation of prune products is effective to provide energy, dietary fiber and water, and to relieve constipation symptoms for constipated adults.

Osteoporosis is a major health problem confronting middle-aged women today. Enhancing calcium intake in early adulthood can increase the rate of calcium gain in bone. In this study, we investigated the association of bone health-related nutritional knowledge levels with calcium-related dietary behavior and nutrition education among women. Data were collected using questionnaires from 347 women aged 20~30 residing in Gyeonggi-do. Subjects were categorized into two groups according to their bone health-related nutritional knowledge (high or low-knowledge group). Knowledge related to bone health and calcium, and dietary habits was assessed, and the preference for and intake frequency of calcium-rich food were collected and analyzed using food frequency questionnaires. The high-knowledge group showed a significantly higher rate of nutritional education experience (33.9%) when compared with the low-knowledge group (18.9%). Not only were the perceptions regarding milk and dairy products more positive in the high-knowledge group (P<0.05), but the intake frequency of calcium-rich foods, such as tofu, soybean, and anchovies, was also higher in this group compared to the low-knowledge group (P<0.05). Overall, the preference for all calcium-rich foods was positively correlated to their intake frequency (P<0.05). Nutrition education experience and the recognition of the need for such education were positively correlated with the bone health-related nutrition knowledge score (P<0.05). In conclusion, bone health-related nutritional knowledge can affect calcium-related dietary behavior and increase the intake of calcium-rich food of 20~30-year-old women and this can contribute to the prevention of osteoporosis. To improve bone health-related nutritional knowledge among young women, it may be important to provide nutrition education.

The aim of this study was to develop various types of a dish frequency questionnaire (DFQ) for estimating the habitual sodium intake and to evaluate the validity of a 125 item dish frequency questionnaire (DFQ 125) with the DFQ 70, DFQ 36 and DFQ 15. For the DFQ 125, one hundred and twenty five dish items were selected based on the information of sodium content of a one serving size, consumption frequency and dish items that contributed most to the variation of sodium intake. Frequency of consumption was determined through nine categories ranging from more than 3 times a day to almost never to indicate how often the specified amount of each food item was consumed during the past 6 months. The sodium intake estimated with DFQ 125 was $5775.0{\pm}3636.3mg$, 12.6% higher than that estimated with a 24 hr urine analysis ($5009.7{\pm}1541.9mg$) and significant correlation was observed between them (r=0.3315, p<0.001). When sodium content in broth leftover was subtracted from the total intake, the actual sodium intakes was decreased to $5309.6{\pm}3076.6mg$, which was 3.2% higher than that with a 24-hr urine analysis. Overall, 56% of subjects in the lowest quintile of sodium intake computed with DFQ 125 were also in the lowest of adjacent quintile while categorization into the opposite quintile were 4.9%. DFQ 70 was developed from DFQ 125 by omitting the food items not frequently consumed, selecting the dish items that showed higher sodium content per one portion size and higher consumption frequency. The sodium intake estimated with DFQ 70 ($5026.6{\pm}3107.1mg$) showed only 0.2% difference from that estimated with a 24-hr urine analysis, significant correlation with it (r=0.3199, p<0.001) and higher proportion of subjects to be classified into the same or adjacent quintile. The sodium intake estimated with DFQ 36 or DFQ 15 was also significancy correlated with that estimated with a 24-hr urine analysis (r=0.3441, p<0.001; r=0.321, p<0.001 respectively) and more. The proportion of subjects was classified into the same or adjacent quintile. However, the actual sodium intake estimated with DFQ 36 or DFQ 15 were $3534.0{\pm}1804.6mg\;and\;2508.0{\pm}1261.5mg$, respectively, 31.3% or 51.3% less than that estimated with a 24-hr urine analysis. It seems the DFQ 125 with subtraction of sodium content in broth leftover or DFQ 70 can be used quantitatively to estimate sodium intake of adults. DFQ 36 or DFQ 15 can be used as a screening tool or to assess the changes of sodium intake after nutrition education.

This study was aimed at examining the pattern of dietary fat intake of 120 university female students living in Kongju city in order to provide baseic data for establishing the dietary grideline of desirable fat intake. The subjects were divided into three groups according to living arrangenment ; family home(FH), or dormitory(DM), or self-boarding house(SB). Fat consumption of subjects was surveyed by two-day food records, and profiles of fatty acid and cholesterol taken were calculated based upon the data reported their contents of foods. The result was that mean daily fat intake was 42$\pm$2g for FH, 48$\pm$4g for DM and 41$\pm$3g for SB. The calorie intake by fat was 20.8, 21.5, and 20.4% respectively. The ratio of P/M/S was 1.3/1.7/1 for FH, 1.3/1.6/1 for DM and 1, .5/1.5/1 for SB. And the ratio of n-6/n-3 fatty acid was 5.2/1 for FH, 8.3/1 for DM and 7.2/1 for SB. Daily cholesterol intake was 208$\pm$20mg for FH, 223$\pm$29mg for DM and 251$\pm$27mg for SB. In addition, intake of n-3 fatty acid was 1.2$\pm$0.2g for FH, 0.9$\pm$0.1g for DM and 1.2$\pm$0.2g for DB. Considering the food source of fatty acids, saturated fatty acid and monounsaturated fatty acid were taken primarily from animal foods, especially milk and milk products, and n-6 polyunsaturated fatty acid was taken from vegetable oils and fats. As a major source of n-3 fatty acid, linolenic acid was obtained through vegetable oils and fats, and eicosapentaenoic acid and docosahexaenoic acid were provided by fishes and their products. There patterns of fatty acid intakes did not differ according to living arrangement. The above results showed that intakes of fat and cholesterol, and ratios of P/M/S and n-6/n-3 fatty acid were overall desirable in all groups. However, intake of n-3 fatty acid was low in all groups. Therefore, consumption of perilla oil, legumes and fishes as a source of n-3 fatty acid should be increased by substituting other food source which provide fats and oils because calorie intake by fat was enough in these subject.

BACKGROUND/OBJECTIVES: This study was conducted to compare the overall changes in dietary intake and metabolic syndrome risk parameters in Vietnamese marriage-based female immigrants over time. SUBJECTS/METHODS: The subjects of this study were 581 Vietnamese marriage-based female immigrants, who were recruited from local clinical centers in Korea. Baseline data were collected from 2006-2011 and the follow-up data were collected from 2012-2014. Dietary food intake was assessed by a 1-day 24-hour recall method. RESULTS: Compared to the baseline, the mean body weight, body mass index, waist circumference, high density lipoprotein (HDL)-cholesterol, systolic blood pressure and diastolic blood pressure increased while the fasting blood sugar, triglycerides and low density lipoprotein-cholesterol decreased at follow-up. The total consumption of foods such as vegetables/fruits/seaweeds/mushrooms, oil and fat, and eggs decreased during the follow-up period, whereas the consumption of sugars, beverages and meats increased. Partial correlation between the rate of change [(Follow-up - Baseline) / Baseline ${\times}100$] in metabolic syndrome risk parameters and food intake after controlling for confounding factors showed that the waist circumference was positively correlated with either the total plant food intake (r = 0.1042, P = 0.0129) or the total food intake (r = 0.0880, P = 0.0359). The plasma levels of total cholesterol (r = -0.1918, P = 0.0289) and HDL-cholesterol (r = -0.1424, P = 0.0007) were negatively correlated with the percentage of total intake from plant food, and HDL-cholesterol levels were positively correlated with the intake of total animal food (r = 0.0980, P = 0.0217). The serum C-reactive protein levels were positively correlated with the total intake of animal food (r = 0.2374, P < 0.0001) or the percentage of total intake from animal food (r = 0.1346, P = 0.0016). CONCLUSIONS: These results suggest that the change rate of dietary intake such as total plant food or animal food is associated with the change rates of metabolic syndrome risk parameters.

본 연구는 선형계획법을 이용하여 현재의 식품섭취패턴에서 크게 벗어나지 않으면서 영양섭취기준을 충족하는 한국 성인의 최적 식품섭취패턴을 설계하였고, 주요 결과는 다음과 같다. 식품품목별 실제섭취량과 최적섭취량을 비교하였을 때 실제섭취량보다 최적섭취량이 높게 나타나 영양섭취기준을 충족하기 위해서 현재보다 섭취량을 더 늘릴 필요가 있는 식품품목으로 모든 집단에서 공통적으로 채소류, 50 ~ 64세 남성을 제외한 집단에서 우유 유제품류인 것으로 나타났다. 50 ~ 64세를 제외한 여성에서는 채소류, 우유 유제품류 이외에도 과일류도 섭취량을 더 높여야 하는 식품품목으로 나타났다. 모든 남성 집단과 19 ~ 29세를 제외한 여성 집단에서 김치의 최적섭취량이 실제 섭취량보다 낮게 나타나 김치는 덜 섭취해야 하는 식품품목인 것으로 파악되었다. 또한 조미료에 대해서는 모든 집단에서 공통적으로 최적섭취량이 0 g으로 산출되었다. 이에 선형계획법을 이용해서 설계한 최적 식품섭취패턴에서 조미료의 최적섭취량이 실생활에서 실현 불가능한 0 g으로 산출되었기 때문에 설계한 최적 식품섭취패턴의 실현성을 높이기 위해서는 나트륨의 목표섭취량을 실제섭취량이 고려된 보다 현실적인 기준으로 재설정할 필요가 있다.
