The prevalence of diabetes is increasing now in Korea because of westernized diet and so on. Korean diabetic patients show some different characteristics such as being less obese from western ones. Korean diet, especially traditional 'sets of dishes' serving diet, is more balanced in terms of nutrition than that of western. Korea diet thus is more beneficial than western one.

Objectives: This systematic review of cohort studies aimed to identify any association between specific dietary patterns and risk of colorectal cancer (CRC). Dietary patterns involve complex interactions of food and nutrients summarizing the total diet or key aspects of the diet for a population under study. Methods and materials: This review involves 6 cohort studies of dietary patterns and their association with colorectal cancer. An exploratory or a posteriori approach and a hypothesis-oriented or a priori approach were employed to identify dietary patterns. Results: The dietary pattern identified to be protective against CRC was healthy, prudent, fruits and vegetables, fat reduced/diet foods, vegetables/fish/poultry, fruit/wholegrain/dairy, healthy eating index 2005, alternate healthy eating index, Mediterranean score and recommended food score. An elevated risk of CRC was associated with Western diet, pork processed meat, potatoes, traditional meat eating, and refined grain pattern. Conclusion: The Western dietary pattern which mainly consists of red and processed meat and refined grains is associated with an elevated risk of development of CRC. Protective factors against CRC include a healthy or prudent diet, consisting of vegetables, fruits, fish and poultry.

BACKGROUND/OBJECTIVES: Previous studies have indicated that when compared to young mice, old mice have lower global DNA methylation and higher p16 promoter methylation in colonic mucosa, which is a common finding in colon cancer. It is also known that a Western-style diet (WSD) high in fat and calories, and low in calcium, vitamin D, fiber, methionine and choline (based on the AIN 76A diet) is tumorigenic in colons of mice. Because DNA methylation is modifiable by diet, we investigate whether a WSD disrupts DNA methylation patterns, creating a tumorigenic environment. SUBJECTVIES/METHODS: We investigated the effects of a WSD and aging on global and p16 promoter DNA methylation in the colon. Two month old male C57BL/6 mice were fed either a WSD or a control diet (AIN76A) for 6, 12 or 17 months. Global DNA methylation, p16 promoter methylation and p16 expression were determined by LC/MS, methyl-specific PCR and real time RT-PCR, respectively. RESULTS: The WSD group demonstrated significantly decreased global DNA methylation compared with the control at 17 months (4.05 vs 4.31%, P = 0.019). While both diets did not change global DNA methylation over time, mice fed the WSD had lower global methylation relative to controls when comparing all animals (4.13 vs 4.30%, P = 0.0005). There was an increase in p16 promoter methylation from 6 to 17 months in both diet groups (P < 0.05) but no differences were observed between diet groups. Expression of p16 increased with age in both control and WSD groups. CONCLUSIONS: In this model a WSD reduces global DNA methylation, whereas aging itself has no affect. Although the epigenetic effect of aging was not strong enough to alter global DNA methylation, changes in promoter-specific methylation and gene expression occurred with aging regardless of diet, demonstrating the complexity of epigenetic patterns.

Purpose: Immunization with Porphyromonas gingivalis heat shock protein 60 (PgHSP60) may have an immunoregulatory effect on atherogenesis. The aim of this study was to determine whether nasal immunization with a PgHSP60 peptide could reduce atherosclerotic plaque formation in apolipoprotein E knockout (ApoE KO) mice. Methods: Seven-week-old male ApoE KO mice were assigned to receive a normal diet, a Western diet, a Western diet and challenge with PgHSP60-derived peptide 14 (Pep14) or peptide 19 (Pep19), or a Western diet and immunization with Pep14 or Pep19 before challenge with Pep14 or Pep19. Results: Atherosclerotic plaques were significantly smaller in mice that received a Western diet with Pep14 nasal immunization than in mice that received a Western diet and no Pep14 immunization with or without Pep14 challenge. An immunoblot profile failed to detect serum reactivity to Pep14 in any of the study groups. Stimulation by either Pep14 or Pep19 strongly promoted the induction of CD4⁺CD25⁺ forkhead box P3 (FoxP3)⁺ human regulatory T cells (Tregs) in vitro. However, the expression of mouse splenic CD4⁺CD25⁺FoxP3⁺ Tregs was lower in the Pep14-immunized mice than in the Pep14-challenged or Pep19-immunized mice. Levels of serum interferon gamma (IFN-γ) and transforming growth factor beta were higher and levels of interleukin (IL) 10 were lower in the Pep14-immunized mice than in the other groups. Induction of CD25^- IL-17⁺ T helper 17 (Th17) cells was attenuated in the Pep14-immunized mice. Conclusions: Nasal immunization with Pep14 may be a mechanism for attenuating atherogenesis by promoting the secretion of IFN-γ and/or suppressing Th17-mediated immunity.

The dramatic increase in colorectal cancer incidence in the population of East Asia indicates that diet and lifestyle play a role in colorectal cancer risk. Colorectal cancer prevention and etiologic studies have long provided dietary modification strategies for colorectal cancer prevention. In this review, we provide an overview of the epidemiologic evidence on the association between diet and colorectal cancer risk. Several cohort studies and a few intervention studies, most conducted in Western countries, have shown a possible link between red and processed meat, alcoholic beverages, calcium, vitamin D, vitamin B and the Western dietary pattern with colorectal cancer development. For colorectal cancer prevention in both Western and Asian populations, dietary modification is a key component of colorectal cancer prevention.

BACKGROUND/OBJECTIVES: Prior studies, mostly conducted in Western countries, have suggested that the low cost of energy-dense foods is associated with an increased risk of obesity. This study aimed to investigate the association between food costs and obesity risk among Koreans who may have different food cost and dietary patterns than those of Western populations. SUBJECTS/METHODS: We used baseline data from a cohort of 45,193 men and 83,172 women aged 40-79 years (in 2006-2013). Dietary intake information was collected using a validated food frequency questionnaire. Prudent and Western dietary patterns extracted via principal component analysis. Food cost was calculated based on Korean government data and market prices. Logistic regression analyses were performed to investigate the association of daily total, prudent, and Western food cost per calorie with obesity. RESULTS: Men in the highest total food cost quintile had 15% higher odds of obesity, after adjusting for demographic characteristics and lifestyle factors (adjusted odds ratio, 1.15; 95% confidence interval, 1.08-1.22; P-trend < 0.001); however, this association was not clear in women (P-trend = 0.765). While both men and women showed positive associations between prudent food cost and obesity (P-trends < 0.001), the association between Western food cost and obesity was only significant in men (P-trend < 0.001). CONCLUSIONS: In countries in which consumption of Western foods is associated with higher food costs, higher food costs are associated with an increased risk of obesity; however, this association differs between men and women.

The acceptance and dining behavior of Taegu residents for western foods were surveyed through the questionnaire to provide basic information for the diet improvement. The results were as follows: 1. The preliminary test showed that 19 western foods had high preference among them in the order of ice cream, fried chicken, fried potato, coffee, salad, pizza, soup, pork cutlet, hamburger sandwich, hamburger steak, potato croquette, curry rice, omelet rice, beef steak, spaghetti, com flakes, hashed rice, and omelet. Although a diversity was observed depending upon the age groups, the persons in their thirties generally had high preference on most western foods. 2. The recognition types of housewives to the western food were grouped into the merits of meal, disadvantages of meal, nutritive values, and cooking convenience. In order to have western food, 54.5% of the respondents went to restaurants, mainly family restaurant, however, the level of frequency was very low.

Coronary artery disease (CAD) such as angina pectoris and myocardial infarction(MI) have been considered the major cause of death for decaddes . THeir incidence and prevalence are still increasing . Numerous studies have been done on the risk factor analysis of CAD in Western countries. Since the diet in Western countries is different from that in Korea it is difficult to assume that the Korean diet has the same effects as its western counterpeart on the development of CAD . THus the gudidelines for the Western CAD patients can no totally be applied to Koreans. This study was conducted to investigate the relationship between diet and CAD in Koreans. Subjects were comprised of patients admitted to the hospital for chest pain with poxxilbe CAD (men 129, women 65) . They were divided into the following three groups according to angiographic results ; angiogrphically normal coronary artery group (control), single vessel disease group(SVD) and multiple vessel disease group (MVD) . Intakes of dietary fatty acids and other nutrients were assessed by the semiquantitative food frequency method. Blood was also obtained from subjects for serum lipid analysis. Serum lipid profiles of men were clearly different form those of women. For men, serum choesterol levels (or LDL or LDL/HDL) seemed to be higher in the MVD group compared to the control and SVD groups, while TG level was significantly higher in the MVD group for women. Both men and women showed significantly higher caloric , fiber and vitamins C and A intakes in the MVD group than in the other two groups. Higher caloric intakes was due to higher intakes of carbohydrate and protein rather than fat intake. In terms of fatty acids intake, there were no significant differences among the three groups . Smoking seemed to have great effect on eating patterns in CAD patients. Smokers and ex-smokers showed significantly higher intakes of most nutrients including individual fatty acids that non-smokers. The results of stepwise regression showed that moderate alcohol intake decreases LDL levels and increases HDL levels and smoking seems to lowe HDL levels in CAD patients.
