The nutritional status is America has been monitored by National Monitoring System since 1960's, mainly conducted by United States Department of Agriculture. The data from these programs were computerized and distributed to researchers. Researchers have manipulated and recalculated the data to produce meaningful results. Korean nutritional status has been investigated by National Nutrition Survey ever year, including food consumption, biochemical measurements and demographic variables. The Korean Nutritional Survey has not been organized and integrated as much as the nutritional survey in the United States and its results have been presented no more than as a report. Its raw data should be distributed to researchers and researchers could use the data to get more information. The purpose of this study is to compare the measurement of food consumption in Korean and America using Korean Nutrition Survey and Continuing Survey of Food Intake by Individuals(CSFII), respectively, and to compare the consumption of fat and foods with a high fat content. The fat consumption in the Unite States has been decreased from more than 40% of total energy intake to 35%, while Koreas have consumed more fat according to the economic growth. However, the fat consumption in Korea was still much lower than that in the United States. Korean should pay attention to saturated fat consumption(animal fat), especially rich middle aged men, since they ate meat as much as much as men in the United States according to a recent study. In America availability of food with a low fat content(e.g. low-fat milk) and new recipes along with nutritional education has decreased fat consumption, especially animal fat, any more. Also, each consumption of polyunsaturated fat and saturated fat should be measured since the ratio of them are more important for preventing heart disease and some cancers.

Malnutrition is common and the major risk factor of mortality of end stage renal disease (ESRD) patients. The aim of this study is to assess nutritional status of malnutrition patients on dialysis by various methods and compare nutritional parameters of continuous ambulatory peritoneal dialysis (CAPD) patients with hemodialysis patients. 137 patients on dialysis from April 2009 to July 2013 were enrolled. Nutritional parameters of 66 CAPD and 71 hemodialysis patients were investigated by anthropometry, biochemical study, diet analysis and questionnaires. Malnutrition patients were selected by body mass index (BMI), serum albumin and pre-albumin based on International Society of Renal Nutrition and Metabolism (ISRNM) diagnostic criteria for protein-energy wasting and compared with non-malnutrition patients. In comparison of CAPD and hemodialysis patients, most anthropometric values showed no significant difference except total body water (TBW). TBW was lower in CAPD patients (P=0.024). Although serum albumin was slightly higher in hemodialysis patients (P=0.047), pre-albumin were significantly higher in CAPD patients (P=0.000). Serum blood urea nitrogen (BUN) was higher in hemodialysis patients (P=0.000). In diet analysis, Total calorie (P=0.000) and total cholesterol (P=0.012) intakes were higher in CAPD patients. Mean subjective global assessment (SGA) grade was higher in CAPD patients (P=0.003). Several nutritional parameters of CAPD patients were better than hemodialysis patients implying more intensive therapeutic approach may be needed for hemodialysis patients. We have to understand multiple factors contributing malnutrition of ESRD patients and individualized therapeutic approach is needed.

The purpose of this study was to collect basic data on the prevention of and education about diabetes mellitus for the nutritional management of a diabetes mellitus risk group. The study which took place in Kangbukgu, Seoul, involved a diabetes mellitus risk group (DMR $\geq$ 110 mg/dL, 61), of males and females, aged 36 to 68 years, and a group of healthy people as a control group ( < 110 mg/dL, 183), using luting blood sugar (FBS) levels. The proportion of people in the abnormal range was higher in the DMR than that of control group for total cholesterol, high-density lipoproteins-cholesterol (HDL-C), total protein, glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and creatinine. Particularly with respect to serum protein the proportion in the DMR in abnormal range (p < 0.05) was significantly higher than that of the control group. The proportion in the DMR with a family history of disease was significantly higher than that of the control group (p < 0.01). Using body mass index (BMI), waist-hip ratio (WHR) and relative body weight (RBW), the obesity indices in the DMR was higher than that of the control group. Comparing the DMR and the control group with respect to dietary habits, it seems that the DMR had more undesirable dietary habits than the control group. When the intake of each nutrient for the DMR and the control group was compared to the Korean recommended dietary allowances (RDA), the proportion of excess intake and deficient intake in the DMR was higher than that of the control group. The DMR showed a greater undesirable dietary intake pattern as compared to that of the control group, based on the RDA. With respect to the dietary diversity score (DDS) and the mean adequacy ratio (MAR) for quality estimation of the overall flood intake, the DMR showed a feater undesirable pattern than the control group. According to the above results, the DMR tended to have more undesirable eating habits when compared to the control group. Therefore, to provide a more efficient nutritional education program for the DMR we must conduct lurker studies on eating habits, so as to provide systematic nutritional management based on theme differences between the DMR and the control group.

BACKGROUD/OBJECTIVES: The objective of this study was to investigate the effects of vitamin C on inflammation, tumor development, and dysbiosis of intestinal microbiota in an azoxymethane (AOM)/dextran sulfate sodium (DSS)-induced inflammation-associated early colon cancer mouse model. MATERIALS/METHODS: Male BALB/c mice were injected intraperitoneally with AOM [10 mg/kg body weight (b.w)] and given two 7-d cycles of 2% DSS drinking water with a 14 d inter-cycle interval. Vitamin C (60 mg/kg b.w. and 120 mg/kg b.w.) was supplemented by gavage for 5 weeks starting 2 d after the AOM injection. RESULTS: The vitamin C treatment suppressed inflammatory morbidity, as reflected by disease activity index (DAI) in recovery phase and inhibited shortening of the colon, and reduced histological damage. In addition, vitamin C supplementation suppressed mRNA levels of pro-inflammatory mediators and cytokines, including cyclooxygenase-2, microsomal prostaglandin E synthase-2, tumor necrosis $factor-{\alpha}$, Interleukin $(IL)-1{\beta}$, and IL-6, and reduced expression of the proliferation marker, proliferating cell nuclear antigen, compared to observations of AOM/DSS animals. Although the microbial composition did not differ significantly between the groups, administration of vitamin C improved the level of inflammation-related Lactococcus and JQ084893 to control levels. CONCLUSION: Vitamin C treatment provided moderate suppression of inflammation, proliferation, and certain inflammation-related dysbiosis in a murine model of colitis associated-early colon cancer. These findings support that vitamin C supplementation can benefit colonic health. Long-term clinical studies with various doses of vitamin C are warranted.

This study examined the relationship among plasma homocysteine, folate, and vitamin $B_{12}$ levels and neurocognitive function in 118 community-dwelling elderly subjects (mean age, $75.1{\pm}6.7$ years). The Mini-Mental State Examination (MMSE-KC) was used to screen and assess neurocognitive function in the participants. Dietary intake data including the use of dietary supplements were obtained using the 24-hour recall method by well-trained interviewers. Plasma folate and vitamin $B_{12}$ concentrations were analyzed by radioimmunoassay, and homocysteine was assessed by a high performance liquid chromatography-fluorescence method. The proportions of participants with suboptimal levels of plasma folate (< 3 ng/mL), vitamin $B_{12}$ (< 221 pmol/mL), and homocysteine (> $15{\mu}mol/L$) were 16.1%, 5.9%, and 21.2%, respectively. A multiple regression analysis showed that plasma homocysteine was negatively associated with plasma folate and vitamin $B_{12}$ levels. The MMSE-KC test scores were significantly associated with plasma homocysteine and folate, but not with vitamin $B_{12}$, after adjusting for age, gender, body mass index, living with spouse, education, current smoking, energy intake, and chronic diseases such as hypertension, diabetes, thyroid disease, dyslipidemia, stroke, and cardiovascular disease. A general linear model adjusted for covariates revealed that MMSE-KC test scores increased from the lowest to the highest quartiles of vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, vitamin $B_{12}$, and vitamin C intake (p for trend = 0.012, 0.039, 0.014, 0.046, 0.026, respectively). These results indicate that the problem of folate inadequacy and hyperhomocysteinemia are highly prevalent among community-dwelling elderly people and that dietary intake of the B vitamins and vitamin C is positively associated with cognitive function scores.

aksun(藥饍), or 'Traditional oriental medicine nutrition therapy', is expected to be an effective nutritional intervention for the patients suffering from chronic diseases. However, there are no systemized protocol that utilize Yaksun as an effective nutrition therapy for Asian patients even though they are accustomed to traditional oriental diet. We investigated the possibility of using Yaksun for developing an effective Medical Nutrition Therapy for Asian patients and proposed factors that have to be considered. Articles published between 1995-2012 about MNT (Medical Nutrition Therapy) and Yaksun were reviewed. Male and female patients of two Korean Medicine Hospitals (n=93) and one Korean Medicine Clinic (n=20) answered a questionnaire asking about their thoughts on the effectiveness of nutritional intervention for their disease management and about their expectations toward Medical Nutrition Therapy on Korean Medicine. 92.9% of the patients have perceived that nutritional intervention is important in disease management. 79.6% of the patients have positively responded that they are willing to use the Medical Nutrition Therapy on Korean Medicine as a clinical nutrition therapy if developed. Female patients, aged in their forties and fifties, educated equivalent to high school graduates and more, and who visited Korean medicine clinic were most interested in the Medical Nutritional Therapy on Korean Medicine. The factors considered in developing the protocol are 1. effectiveness 2. safety 3. expense, in order of importance. Nutritional intervention protocol using Yacksun is necessary for the patients. Medical Nutrition Therapy on Korean Medicine is in need of development. Accumulated case-control studies, cost effectiveness studies, and studies about programming and systemizing the protocol are needed.

Objectives: This study aims to compare changes in physical factors, health behaviors, eating habits, and nutritional intake among Korean male and female adults over a period of three years (2019-2021) before and after the outbreak of coronavirus disease 2019 (COVID-19). Methods: This study utilized raw data from the 8th Korea National Health and Nutrition Examination Survey (2019-2021). The participants in this study included 6,235 individuals in 2019, 5,865 individuals in 2020, and 5,635 individuals in 2021. Individuals whose daily energy intake was less than 500 kcal or exceeded 5,000 kcal were excluded from the study. Results: In comparison to 2019, overweight/obesity rates, weight, waist circumference, weekend sleep hours, and resistance exercise days/week increased in both male and female during the COVID-19 pandemic. Regarding eating habits, the proportions of people skipping breakfast, not eating out, consuming health supplements, and recognizing nutritional labels increased in 2020 and 2021, whereas the rate of skipping dinner decreased. Total energy intake has continued to decrease for the two years since 2019. A comparison of nutrient intake per 1,000 kcal before and after the outbreak of COVID-19 revealed that intake of nutrients, including protein, phosphorus, iron, vitamin A, riboflavin, and niacin increased, while folic acid intake decreased. In male, calcium, phosphorus, riboflavin, and niacin intakes increased, whereas iron, vitamin C, and folic acid intakes decreased. In female, phosphorus, iron, vitamin A, and riboflavin intake increased significantly, while protein and niacin intake decreased significantly. Conclusions: After COVID-19, the obesity rate, breakfast skipping rate, health supplement intake, and nutritional label use increased, while the frequency of eating out, dinner skipping rate, and total energy intake decreased. These environmental changes and social factors highlight the need for nutritional education and management to ensure proper nutritional intake and reduce obesity rates in the post-COVID-19 era.

Objectives. The current study aims to determine the correlation between nutritional status upon presentation and disease severity, as well as treatment and survival outcomes. Methods. Patients who were diagnosed with deep neck infection, underwent at least one surgical drainage/debridement, and had more than 1 week of hospitalization at a tertiary medical center from 2007 to 2015 were retrospectively included. Thereafter, initial serum albumin, C-reactive protein (CRP), and body mass index (BMI) were reviewed. Results. A total of 135 patients were included in the final analysis. Accordingly, the proportion of patients with simultaneous mediastinitis (21.0%), necrotizing fasciitis (12.9%), disease extent >1 cervical level (72.6%), mean CRP (22.4 mg/dL), mean length of hospitalization (25.0 days), and mean 1-week follow-up CRP (7.2 mg/dL) was significantly higher in the hypoalbuminemia group (initial serum albumin <3.0 g/dL) than in the normoalbuminemia group (all P<0.05). No significant correlations had been observed according to BMI status. After adjusting for age and Charlson comorbidity index, odds ratios for the following outcomes were calculated in patients initially presenting with hypoalbuminemia: simultaneous mediastinitis (3.07), necrotizing fasciitis (7.89), disease extent >1 cervical level (2.12), initial serum CRP over 20 mg/dL (3.79), hospitalization of more than 14 days (4.10), 1-week follow-up CRP over 5 mg/dL (3.78), and increased duration for an over 50% decrease in initial CRP (2.70) (all P<0.05). Although intravascular albumin replenishment decreased the proportion of patients with hypoalbuminemia after 2 weeks (P<0.05), it did not significantly predict better treatment outcomes. Conclusion. Among the markers reflecting an individual's nutritional state, an initial serum albumin of less than 3.0 g/dL was an independent serologic marker predicting increased disease severity and complications in patients with deep neck infection.

목 적: 소아 크론병의 치료방법으로 스테로이드가 주로 사용되어 왔으나 스테로이드는 부작용이 많으며 특히 소아에서는 성장지연을 초래할 수 있다. 최근 성분식이 요법이 크론병의 치료에 도입되어 몇몇 장점들이 보고되고 있다. 이에 본 연구에서는 소아 크론병의 치료로서 사용된 성분식이 요법의 임상적 효과에 대해서 평가하고자 하였다. 방 법: 2001년부터 2005년까지 서울아산병원 소아과에서 크론병으로 진단된 환아 중 성분식이 요법을 받은 환아 11명과 스테로이드 치료를 받은 환아 19명의 의무기록지를 통하여 병의 관해, 재발, 성장에 미치는 영향을 후향적으로 비교 분석하였다. 결 과: 성분식이 요법을 시작한 11명 중 10명과 스테로이드 치료를 시작한 19명 중 18명에서 1년간 치료를 지속할 수 있었다. 치료 6주 안의 관해율에 있어서는 성분식이 군과 스테로이드 군 사이의 통계학적인 유의성은 없었다. 1년간의 경과 관찰기간 중 성분식이 군의 재발률은 스테로이드 군에 비해 유의하게 낮았다. 1년 뒤의 키성장을 z-score를 사용하여 비교하였으며 성분식이 군의 delta z-score는 $0.37{\pm}0.36$, 스테로이드 군은 $0.29{\pm}0.44$였으나 유의성은 없었다. 1년 뒤의 체중의 경우, 성분식이 군의 delta z-score가 $0.64{\pm}0.60$였고 스테로이드 군은 $0.63{\pm}0.84$였으나 역시 유의성은 없었다. 결 론: 성분식이 요법은 크론병의 관해, 성장 면에서 스테로이드와 차이가 없었으나 유의하게 낮은 재발률을 보였다. 이에 소아 크론병의 1차 치료로서 성분식이 요법을 사용할 수 있을 것으로 생각되나 이에 대한 보다 많은 환자를 대상으로 한 연구가 필요하다고 생각된다.
