The aim of this study was to develop a KDPS (Korean dietary pattern score) to assess dietary patterns and diet quality of Koreans from a food culture perspective. The KDPS was applied to dietary data collected during the Korean National Health and Nutrition Examination Survey of 2007, and the validity and reliability of the KDPS were evaluated. The targets of the study included 2,278 Korean adults aged 20n89 years. The KDPS was developed using the sum of the scores of 13 components. Each component scored up to 10 points and there was a total of 130 points. The first seven components were for the KSMS (Korean-style meal score) and assessed the dietary balance based on the 3-Chup Bansang daily basic table setting. The components numbered 8 to 13 were for the FGS (food group score), which measured the degree of compliance with the six major food groups based on the Korean recommendation for one serving size of grains, meats, vegetables, fruits, milk, and oils. This KDPS was verified through content validity, concurrent-criterion validity, principal components analysis, and a reliability analysis. The results showed that content validity and construct validity were high. The KDPS developed in this study adhered to the Korean dietary pattern and a healthy diet intake. Furthermore, this study presented an integrated index by scoring the Korean style table setting in addition to evaluating meals from a nutrition perspective. This study can be extended to develop a score for assessing.

Breast cancer has been estimated as one of the most common causes of cancer death among women. The major cause of death from breast cancer is the metastatic spread of the disease from the primary tumor to distant sites in the body. Lycopene is one of the major carotenoids in fruits and vegetables including tomatoes. Epidemiological studies have shown that the dietary intake of lycopene is associated with decreased risk of cancer. Although mounting evidence shows the chemopreventive effect of lycopene, the role of lycopene in the prevention of metastatic potential of breast cancer has not been determined yet. In the present study, we investigated the inhibitory effect of lycopene on invasive and migratory phenotypes of two highly aggressive breast cancer cell lines, H-Ras-transformed MCF10A human breast epithelial cells (H-Ras MCF10A) and MDA-MB-231 human breast cancer cells. Here, we report that lycopene significantly inhibits invasion and migration as well as proliferation of H-Ras MCF10A and MDA-MB-231 cells. This study suggested an in vitro anti-cancer and anti-metastatic potential of lycopene. We also showed that activations of ERKs and Akt were inhibited by lycopene in H-Ras MCF10A cells, suggesting that the ERKs and Akt signaling pathways may be involved in lycopene-induced anti-proliferative and/or anti-invasive/migratory effects in these cells. Taken in conjunction with the fact that breast cancer metastasis is one of the most lethal malignancies in women, our findings may provide useful information for the application of lycopene in establishing strategy to prevent the metastatic breast cancer.

Anthocyanins, a class of flavonoids, are natural water-soluble pigments, mainly found in vegetables and fruits. Anthocyanins have attractive pharmacological activities, such as anti-oxidant, anti-inflammatory, anti-cancer, and anti-diabetic effects. The purpose of this study was to investigate the inhibitory effects of the anthocyanin-rich fraction (ANF) from purple sweet potato on high fat diet-induced insulin resistance and hepatic steatosis. C57BL/6J mice were assigned to the following groups (n=8 per group): normal fat diet (NF); high fat diet (HF); high fat diet with ANF 50mg/kg (ANF50). Normal fat or high fat diets were fed for a total of 17 weeks, and ANF was orally administrated for 8 weeks (from 10 to 17 weeks, five times/week). In our results, there were no significant differences in body weight, food intake, and tissue weight upon ANF supplementation. The levels of serum triacylglycerol, total-cholesterol, and glucose were also not affected by ANF supplementation. However, ANF supplementation significantly decreased serum insulin and HOMA-IR levels as well as prevented hepatic fat accumulation in high fat-fed mice. These results show that ANF may be beneficial for improving high fat-induced insulin resistance and protecting against development of hepatic steatosis.

This study was conducted to examine differences in nutrient intakes by the compliance with the Dietary Action Guide for Korean Children. The subjects included 343 elementary school students in Gwangju city. Compliance with the Dietary Action Guide for Children showed that 62.4% of subjects had breakfast everyday; 44.3% of subjects ate vegetables/fruits/milk and dairy products daily; 26.8% of subjects ate a variety of lean meats/fish/eggs/bean products daily; 32.9% of subjects enjoyed outdoor activity everyday and ate according to their energy needs; 40.2% of subjects chose healthy and nutritious foods for snack; and 15.5% of subjects avoided food waste. Intakes of most of nutrients including energy were significantly higher (p < 0.05) in those who complied with the Dietary Action Guide well. Also nutrient intakes had the positive correlation with the scores of Dietary Action Guide (p < 0.05). From these results, nutrient intakes of children were significantly influenced by dietary factors suggested in the Dietary Action Guide for Children. In addition, the results also confirmed that good food behaviors were indispensible to maintaining a proper nutritional status. Based on these results, good food behaviors and practice were critical to secure good health and proper nutritional status for children, and that nutrition education should be strengthened in school as well as at home.

This study was conducted to evaluate the nutrient intakes and the physical activities of mentally retarded persons (MRPs) accommodated in welfare institutions. A total of 194 cases of MRPs (130 males and 64 females) were surveyed through interviews of the 35 caregivers of the institutions during the period from March 2 to 12, 2005. The mean age of the 2nd degree is the highest, and the duration of institution stay of the 2nd degree is the longest. There were no significant differences in height, weight, but there were still significant differences in BMI by the degree of handicap. The MRPs with the 1st degree handicap consumed less nutrients than the MRPs with 2nd or 3rd degree handicaps, except for vitamins C and E. The mean activity factor was $1.737{\pm}0.422$ meaning 'active'. Among the comparative groups, the activity factor of the 2nd handicap degree MRPs was the highest. Note that the percentage of protein is the lowest in the case of the 1st degree handicap. The intake of the folic acid, in particular, was less than the Estimated Average Requirement (EAR) in case of all the MRPs while that of vitamin C, riboflavin and calcium was less than the EAR in case of $65{\sim}80%$ of the MRPs. MRPs with higher activity factors showed higher intakes of most nutrients except vitamin C. MRPs with higher marks in the 'balanced dietary habit' field showed more nutrient intakes. More consumption of vegetables and fruits by the MRPs was recommended. Also, more efficient dietary guidance was recommended for the MRPs.

Objectives: While recent studies showed that coffee consumption reduced the risk of all-cause mortality, no study has examined the effect of coffee consumption on all-cause mortality related to sleep disorders. We aimed to examine whether sleep-related disorders would differently affect the association between coffee consumption and the risk of all-cause mortality among 8,075 adults aged 40 to 69 years. Methods: In a prospective cohort study, the study participants were biennially followed up for 12 years from 2001 to 2012. On each follow-up visit, the participants underwent comprehensive tests including anthropometric examinations, interviewer-administered questionnaires, and biochemical tests. Coffee consumption frequency and the amount were measured using a semi-quantitative food frequency questionnaire. Using death certificate data from Korean National Statistical Office, the vital status of each study participant was identified. Sleep-related disorders were examined with interviewer-administered questionnaires. We estimated Hazard ratios and the corresponding 95% confidence intervals from Cox Proportional Hazard models. Multivariable models were established after adjusting for center, total caloric intake, age, gender, body mass index, physical activity, education, smoking, drinking, hypertension, diabetes, total cholesterol, c-reactive protein, energy-adjusted food groups of refined grains, vegetables, fruits, meat, fish, and dairy. Results: Compared with those who had no coffee consumption, participants who had about three cups of coffee per day showed a reduced risk of all-cause mortality, after adjusting for covariates. Those who had a sleep-related disorder showed no significant effect of coffee consumption on the risk of all-cause mortality, whereas those who had no sleep-related disorders showed significantly reduced risk of all-cause mortality. Conclusions: Our findings suggested that approximately three cups of coffee per day would be beneficial to reduce the risk of all-cause mortality only among adults with no sleep-related disorders. Coffee consumption should be prudent for those with sleep-related symptoms.

The purpose of this study was to verify whether Mediterranean diet, which proved to have a significant effect on preventing dementia for people aged 65 or older, could be well modified to be a Korean-style Mediterranean diet. This study was performed as a randomized-controlled trial for 6 weeks. Functional physical changes, cognitive scores, depression scores and dietary changes were all assessed. The walking speed (P<0.001) and the cognitive scores were statistically improved in only the experimental group (P<0.001), and the depression scores were also significantly improved in only the experimental group (P<0.01). The dietary intake showed a 30% improvement for consuming more than 7 cups per day of vegetables and fruits. When the participants were contacted four months after the end of the study, 90% of them said that the Korean-style Mediterranean diet was feasible and 100% said the nutrition interventions helped them maintain the diet during their daily lives. The results suggest that although the Mediterranean diet can be difficult to apply, any limitations of this healthy diet can be overcome.

This study was conducted to investigate dietary patterns and assimilation of dietary culture of Korean descendants in Yanbian, China compared to Korean. A dietary survey was conducted using one 24-hour recall method from 730 adults over 30 years of age in Yanbian, China and 695 adults over 25 years of age in Kuri, Korea. The average number of food items consumed per day was 14 in Yanbian and 20 in Kuri and there was a significant difference between the two regions(p<0.001). The foods consumed most frequently were rice, salt, the M.S.G. in Yanbian and rice, green onion and garlic in Kuri. The foods consumed most by amount were rice, cucumber, Soju in Yanbian and rice, Kimchi and grape in Kuri. The average number of dishes consumed per day was 6.4 in Yanbian, 9.4 in Kuri and the difference between the two regions was significant(p<0.001). Total number of dishes appeared in the survey was 253 in Yanbian and 494 in Kuri. The dishes consumed most frequently were cooked-rice, beverages, Kimchi, stir-fried eggplant in Yanbian and cooked-rice, Kimchi, coffee, soybean paste stew, in Kuri. The dish groups appeared most frequently were rice, stir-fried foods, vegetables and Kimchi in Yanbian and rice, Kimchi, beverages and fruits in Kuri. Male subjects in Yanbian Consumed alcohol frequently while adults in Kuri consumed coffee more frequently than Yanbian. The major meal patterns were rice+side dish, rice+soup, rice+side dish+Kimchi in Yanbian and rice+soup+side dish+Kimchi, rice+side dish+Kimchi, rice+soup+Kimchi in Kuri. Stir-fried foods, which were consumed 46.6% of all the meals, were dominant side dish in Yanbian, but stir-fried food, seasoned vegetables and grilled food appeared aver 10% in Kuri. There results show that variety of diet of Korean-Chinese in Yanbian was lower than Kuri. Korean-Chinese tend to keep traditional Korean dietary patterns of consuming rice as staple but were adapted to Chinese dietary patterns of consuming stir-fried side dishes. Efforts should be directed toward preserving Korean traditional patterns of dietary culture among Korean-Chinese population.
