Risk of Metabolic Syndrome according to Intake of White Rice and Kimchi in Korean Adults: based on the 6th Korea National Health and Nutrition Examination Survey, 2013–2015: Jin Su Kim, So Hyun Ahn, Sook Mee Son; Korean J Community Nutr 2018;23(6):525-537. Published online December 31, 2018; DOI: https://doi.org/10.5720/kjcn.2018.23.6.525

OBJECTIVES
This study was conducted to examine the relationship between white rice and Kimchi intakes and the risk of metabolic syndrome (Mets) in Korean adults.
METHODS
Dietary intake and health data of 8289 subjects aged 19 years and over from the 2013â€“2015 Korea National Health and Nutrition Examination Survey (KNHANES) were used. Daily total intake of white rice and Kimchi was assessed by 24-hour recall data. Multivariate logistic regression analysis was used to estimate the risk of Mets according to the daily intake of white rice and Kimchi.
RESULTS
The highest intake of white rice and Kimchi was associated with a higher risk of metabolic syndrome (Q1 vs Q5, multivariable adjusted OR=1.45, 95% CI: 1.03â€“2.03) in women. In addition, a significantly increased risk of elevated blood pressure (multivariable adjusted P for trend 0.0459) was associated with a higher intake of white rice and Kimchi in women. There was no significant trend in the risk of metabolic syndrome according to the intake of white rice and Kimchi in men.
CONCLUSIONS
A higher intake of white rice and Kimchi was only associated with an increased risk of metabolic syndrome in women indicating it is necessary to consume more various food groups beside white rice and Kimchi, especially in women.

OBJECTIVES
The objective of this study was to examine the relations between total vegetable and Kimchi intakes and the risk of metabolic syndrome (Mets) in Korean adults.
METHODS
This study used dietary intake and health data of 6668 subjects aged 20 years and over from the 2010â€“2011 Korea National Health and Nutrition Examination Survey (KNHANES). Daily intakes of total vegetables and Kimchi were assessed by 24-hour recall data. The odds ratio of Mets risk according to daily intake of vegetables and Kimchi was analyzed, respectively.
RESULTS
The highest consumption of total vegetables was associated with a lower risk of abdominal obesity (multivariable adjusted OR=0.56, 95% CI: 0.33, 0.93) in men and lower risk of Mets (multivariable adjusted OR=0.67, 95% CI: 0.47, 0.94) in women. Kimchi consumption was not related to the risk of Mets in both men and in women. However, a higher intake of Kimchi was associated with an increased risk of elevated blood pressure (Q1 vs Q5, multivariable adjusted OR=1.34, 95% CI: 0.95, 1.90, P for trend= 0.0261) in women.
CONCLUSIONS
A higher intake of vegetables was associated with decreased risk of abdominal obesity and Mets in both men and women, respectively. A higher consumption of Kimchi was not related to the risk of Mets in both in men and in women. However, a higher intake of Kimchi was associated with an increased risk of elevated blood pressure in women.

Abstract PDF PubReader

OBJECTIVES
The importance of kimchi as a traditional food in Korean cuisine has gradually decreased due to rapid industrialization, economic growth and changes in dietary patterns in Korea. This study aimed to examine the shifts in kimchi consumption by region and by income level between 2005 and 2015 in Korea.
METHODS
Data from the Korea National Health and Nutrition Examination Surveys III (2005) and VI (2015) were used in the study (n=15,558). Intake of kimchi was estimated using a single 24-hour dietary recall. The sample weights were applied in all analyses to reflect population estimates. All statistical analyses were carried out by using SPSS IBM Statistics 20.
RESULTS
Kimchi intake has significantly decreased by 27.6 g/day per capita during the last decade in Korea; 25.0 g for males and 29.9 g for females, respectively. Over the past decade, the decline of kimchi intake has been particularly significant in Seoul, Busan, Incheon, Gyeonggi, and Gwangju, while there has been no significant change in males living in rural areas. The consumption of kimchi across all income levels has decreased, however, the decrease was higher in â€˜middle and low income levelâ€™. The amount of kimchi consumption in 2015 was the highest in â€˜low income levelâ€™. The results were similar after adjusting for gender and age.
CONCLUSIONS
For the past decade, the overall intake of kimchi in Korea has decreased, however, it has been found that the decrease of kimchi intake for males living in the rural areas was not significant. Therefore, in order to keep our traditional kimchi culture and promote a balanced diet including kimchi for Korean, it is necessary to develop more efficient policies and approaches. A variety of dishes using kimchi should be developed, besides merely serving kimchi with rice as a side dish, to increase the consumption of kimchi.

Sodium Intakes of Korean Adults with 24-hour Urine Analysis and Dish Frequency Questionnaire and Comparison of Sodium Intakes According to the Regional Area and Dish Group: Sook Mee Son, Young Sook Park, Hwa Jae Lim, Sook Bae Kim, Yeon Seon Jeong; Korean J Community Nutr 2007;12(5):545-558. Published online October 31, 2007

Abstract PDF: This study was performed to assess the sodium intakes of Korean adults using a 24-hr urine analysis and dish frequency questionnaire (DFQ) according to each dish group and the regional area. The subjects of this study were comprised of 552 adults (male: 267, female: 285), aged 20-59yr residing in the metropolitan area (N = 200), Chungcheng-Do (N = 117), Jeolla-Do (N = 117), and Gueongsang-Do provinces (N = 118). The subjects were recruited from the residents who once participated or are participating in the various health programs offered by the public health center. The number of subjects who completed the 24-hr urine collection was 205 (male : 110, female : 95).The mean age and BMI of the subjects were 39.0+/-11.7 y and 23.1+/-2.9 kg/m2, respectively. The mean systolic and diastolic blood pressure was 119.5+/-15.4 mmHg, and 77.1+/-11.1 mmHg, respectively. Eighteen percent of the subjects responded that they are currently smoking, 36% drinking and 50.4% exercising. Twenty point six percent of the subjects were assessed as having hypertension according to their systolic or diastolic blood pressure(SBP > or = 140 mmHg or DBP > or = 90 mmHg) measurements in the present study. Salt intake of the subject estimated with 24-hr sodium excretion was 12.7 g/d (male : 13.4 g/d, female : 12.1 g/d) based on the sodium excretion rate as 82%. Salt intake estimated with DFQ was 14.7 g/d (male : 16.2 g/d, female : 13.4 g/d), 2 g more than the salt intake estimated with 24-hr urine analysis. The four dish groups that contributed most to the sodium intake in order were kimchi (I1571.4mg), soup and stew (1260.5 mg), fish and shellfish (706.3 mg) and noodle and ramyeon (644.3mg). Salt intake estimated with DFQ was the highest in the subjects of Gueongsang-Do (17.0 g/d), second highest Chungcheong-Do (16.4 g/d) and the lowest in the metropolitan area (13.0 g/d). Subjects of Gueongsang-Do showed the highest sodium intakes in most of the dish group, whereas subjects of the metropolitan area showed the lowest. Residents of Chuncheong-Do revealed the highest sodium intake with kimchi and ofJeolla-Do the higher sodium intake with the main dish (meat, fish and beans). The highest salt percentage of kimchi (3.0+/-0.8%) and soybean paste (14.5 +/-5.1%) were observed in Gueongsang-Do, whereas individuals of the metropolitan area were observed as having kimchi (1.6 +/-0.5%) and soybean paste (7.4 +/-1.6%) with the lowest salt percentage. Men were observed as having more salty kimchi (2.4 +/-0.1%) than women (2.1 +/-0.1%).

The Effect of Kimchi Intake on Free Radical Production and the Inhibition of Oxidation in Young Adults and the Elderly People: Jong Hyen Kim, Jae Du Ryu, Yeong Ok Song; Korean J Community Nutr 2002;7(2):257-265. Published online April 30, 2002

Abstract PDF: This study was performed to investigate the effect of kimchi intake on free radical and oxidative substance production in young adults and the elderly. Daily kimchi intake by people in their twenties (n = 93, 20 to 29 years old) and over sixty-five (n = 143, over 65 years old) in M city were surveyed and blood was drawn to analyze the free radicals in their plasma. The average amount of kimchi intake by the subjects was 115.8 +/- 91.7 g. The amount of kimchi intake of those in their twenties (106.1 +/- 80.6 g) was significantly lower than that of those over sixty-five (125.5 +/- 102.9 g, p<0.05). Concentrations of total free radicals and OH radicals were 27 and 33% greater respectively, in those over sixty-five than in those in their twenties, indicating that more free radicals were produced by the older group. The concentration of GSH was not signiacantly different in the two groups, but that of GSSG in the over sixty-five age group was 53% greater than in the twenties group, which resulted in a 35% reduction in GSH/GSSG in the elderly group. TBARS concentration in the over sixty-five group was 26% greater than that of the twenties group. In order to see the effect of kimchi intake on free radical production, subjects in same age group were divided into two sub groups-the mean over and the mean under groups-according to the average amount of kimchi intake, which was 115.8 g. The total free radicals, the OH radicals, the GSH, the GSSG, and the GSH/GSSG in the twenties group were not significantly different in the two kimchi intake groups. However, those in the over sixty-five group were significantly different. The concentration of total free radicals and OH radicals of the mean over group were 21 and 26% lower respectively, than those of the mean ova. group (p<0.05). The GSH and GSH/GSSG of the mean ova. groups were higher by 8 and 12%, respectively. The correlation coefficient between the kimchi intake and the total free radicals was -0.1862 (p<0.05) and that for GSH/GSSG was 0.1861 (p<0.05). In conclusion, the production of free radicals and oxidative substances increased with age, and kimchi seemed to retard this phenomena.

Abstract PDF: The purpose of this study was to investigate the intake, preference, and utilization of kimchi in female high school students. A questionnaire was used as the instrument of investigation. The subjects were 371 female high school students in Chonbuk province. More than 80% of the subjects had eaten 8 kinds of kimchies Korean cabbage kimchi, cubed radish kimchi, radish leaves kimchi, green onion kimchi, salted cucumber, watery radish kimchi, radish root & leaves kimchi, and Korean wild radish kimchi. The subjects living in urban areas ate more stalk of sweet potato kimchi and leaf mustard kimchi, however the subjects living in rural areas ate more sedum kimchi. The subjects in large families ate more leaf mustard kimchi and sedum kimchi. The preferred kinds of kimchi were radish kimchi, Korean cabbage kimchi, cubed radish kimchi, and cucumber radish kimchi. Seventy-four point four percent of the subjects liked kimchi, whereas 1.6% of them disliked it. The reason eating kimchi was 'custom'(59.0%), 'taste'(30.7%), 'nutrition'(4.3%), 'traditional flod'(2.7%), and 'parents advice'(2.7%). 38.4% of the subjects in urban area ate kimchi for taste whereas 25.0% of them in rural area did. They prefefrred 'well fermented', 'hot', and 'very pungent' kimchi. The preferred dishes made with kimchi were stir-fried rice with kimchi, kimchi stew, pan-fried kimchi, and rice with bean sprouts & kimchi.

Consumers' Response and Purchasing of Traditional Fermented Foods Marketed in Taejon: Nam Sook Koo; Korean J Community Nutr 1997;2(3):388-395. Published online August 31, 1997

Abstract PDF: A survey was conducted to investigate housewives' perception and consumption of Korean fermented foods marketed in Taejon. Most subjects know how to prepare Kimchi(seasoned and fermented vegetables), 65-67% can make Kochujang(fermented red pepper soybean paste), Toenjang(Korean style soysauce) and Jang-atchies(pickled basic side dishes), 56% can make Kuk-ganjang(Korean style coysauce), 45% can make Chonggukjang (fermented soybean) and 34% can make Jot-kals(salt-fermented fish products). With decreasing age(p<0.0001), not many other subjects could make other fermented foods besides Kimchi. The percentages of subjects buying fermented foods were 71.5% for Chin-ganjang(Japanese style soysauce), 51.7% Jot-kals, 27.1%Kochujang, 25.7% Chonggukjang, 20.1% Jang-atchies, 10.4% Toenjang, 5.9% Kuk-ganjang, and 3.8% Kimchi. the uounger in age, the higher the tendency to buy marketed Kimchies(p<0.05) and Kochujang(p<0.01). The resons for purchasing fermented foods were convenience (52.9%), lack of preparation knowledge(17.5%), lack of time for preparation(12.5%), and lack of space for food storage(8.2%). Subjects indicated that their reasons for mot buying were as follows : use of additives or unreliability with regard to manufacturing dates(45%), bad taste(21%), unsanitary treatment(16%) and to keep their indigenous taste(14%). They cosidered expiration dates, taste, crpteria and safety as the important standard in selecting marketed foods. Younger subjects insisted on the improvement of sanitary condition and partial change of taste to increase the consumption of fermented foods. However, older subjects thought it best to keep the taste original for more utilization of fermented foods.
