The known risk factors for atherosclerosis include plasma low density lipoproteins (LDL)or Cholesterol, low PUFA in the diet, hypertension, and high Na intake, obesity, diabetes, lack of exercise, cigarette smoking, sugar, low fiber and nicotinic acid in the diet, sources of Protein foods, and Psychological factors. Among various dietary factors, fat is known as the most serious causative agent for atherosclerosis. The genetic factor is a18o known as an important one but is out of scope in this paper. Since atherosclerosis is a progressive disease which may develop for many years before showing any definitive symptoms, it is very important to develop preventive programs especially in the country like Korea that is not quite overdevelopted as some western countries. In this paper all the factors mentioned above were reviewed and the dietary suggestion were made on the basis of the content of polyunsaturated and saturated fat in the diet to prevent or/and to cure this disease. Most of the available data on diet therapy with emphasis. on P/S ratio were tabulated together. after tile patient's habitual dietary intake is analized the guidelines of personalized fat-controlled diet can be recommended. It is of utmost importance to develop Korean diets for beth prevention and cure of atherosclerosis emphasizing individual eating habit in the near future which can be more Practicaly used both at home and in the hospital.

Purpose: Obesity is associated with a dysregulation of metabolic balance and is regarded as a low grade chronic inflammation. Western-style diet and physical inactivity are leading causes of obesity. This study examined the profiles of forty plasma cytokines and chemokines at the same time in the early stages of high-fat diet-induced obesity using a mouse model. Methods: A total of 30 male CD1 mice, 12 ~ 14 weeks of age, were enrolled. The mice were fed a high-fat diet for 6 weeks to induce obesity. The plasma glucose and triglyceride concentrations were measured using a hexokinase colorimetric assay kit and a serum triglyceride determination kit, respectively. The relative levels of multiple cytokines and chemokines in the plasma were determined using a mouse cytokine array kit. Results: The mice exhibited significant weight gain after 6 weeks of a high-fat diet. The genital fat depot was enlarged along with an increase in the number and the mean size of white adipocytes as early as 4 weeks after a high-fat diet. In addition, the plasma glucose and triglyceride levels increased significantly after 4 weeks of a high-fat diet. Cytokine array analysis revealed a remarkable increase in the expression of both CXCL12 and CXCL13, whereas the proinflammatory cytokines remained low after 4 weeks of a high-fat diet. Conclusion: A significant increase in plasma levels of CXCL12 and CXCL13 was observed after 4 weeks of a high-fat diet, which might induce the migration of B lymphocytes, T lymphocytes, and monocytes from the blood to expanding adipose tissue or fat associated lymphoid clusters, playing a key role in adipose tissue remodeling and local immunity during the early stages of high-fat diet-induced obesity.

Natural products in Chonnam, Korea were screened via anti-angiogenesis experiments, and 1 candidate product was identified, Corni fructus, which exerted dose-dependent inhibitory effects against angiogenesis, adipogenesis, and cell adhesion. C. fructus extract (CFE) exhibits an angiogenesis inhibitory effect superior to that of the EGCG from green tea leaves. The expression level of angiogenesis and adipogenesis-related signal molecules in the western blotting was reduced by increasing the amount of added CFE. Moreover, a diet supplemented with CFE was deemed more effective in inducing weight loss in LB mice than a representative synthetic diet drug, orlistat, which incidently caused the side effect of denuding the mice of their hair. These results indicate that C. fructus may prove to be a useful anti-adipogenic compound, and these in vitro results may be reflected later under in vivo conditions.

The feeding habits of Sebastiscus marmoratus collected from the Western Coastal Waters of Jeju Island between June 2008 and July 2009 were studied based on examination of the stomach contents. A total 254 individuals of S. marmoratus ranged from 13.2 to 29.6cm (mean 20.7cm) in Standard length (SL). S. marmoratus consumed mainly teleosts such as Chromis notata and Sebastes inermis. Its diet also includes shrimps and crabs. The individuals smaller than 15cm SL consumed mainly shrimps, but on the other hand the individuals larger than 25cm SL consumed mainly fishes. The proportion of fish consumption increased with increasing size of S. marmoratus.

We here outlined our study on the variations in intake of nutrients based on four season 7 consecutive day weighed diet records (WDRs) from 80 Japanese female dietitians in 1996 - 1997. Furthermore, we reviewed Japanese, Korean and international articles investigating variability in consumption of foods as well as nutrients. The relative contributions of variation for all nutrients by person were greater than those by day, week and season. Within individual variances were greater than that between individual variances, being generally observed in Korea and in the world. The ratios of within- vs. between-individual variations ranged from 1.3-26.9 in our study, the ratios being greatest in Korean, followed by Japanese and western people. Based on within individual coefficients of variation, minimal days necessary for estimating nutrient consumption per person within 10％ (20％) of the true mean with 95％ confidence intervals were estimated. They ranged from 10-35 (3-9) days for energy and major nutrients and 15-640(4-160) days for micro-nutrients. Two Japanese studies reported that the ratios for foods were as a whole greater than those for nutrients, except for cereals, rice and milk. (J community Nutrition 5(2) : 72-82,2003).

We investigated the effect of paternal folate status on folate content and expression of the folate transporter folate receptor ${\alpha}$ ($FR{\alpha}$) in rat placental tissues. Rats were mated after males were fed a diet containing 0 mg of folic acid/kg of diet (paternal folate-deficient, PD) or 8 mg folic acid/kg of diet (paternal folate-supplemented, PS) for 4 weeks. At 20 days of gestation, the litter size, placental weight, and fetal weight were measured, and placental folate content (n=8/group) and expression of $FR{\alpha}$ (n=10/group) were analyzed by microbiological assay and Western blot analysis, respectively. Although there was no difference observed in litter size or fetal weight, but significant reduction (10%) in the weight of the placenta was observed in the PD group compared to that in the PS group. In the PD group, placental folate content was significantly lower (by 35%), whereas $FR{\alpha}$ expression was higher (by 130%) compared to the PS group. Our results suggest that paternal folate status plays a critical role in regulating placental folate metabolism and transport.

Over the past few decades, changes in patterns of behavior (e.g., diet, smoking, alcohol consumption, and physical activity) have led to major changes in health status, characterized by increases in obesity, Type II diabetes mellitus, cardiovascular disease, and some cancers. This epidemiologic transition is largely the result of rapid increases in immigration to developed countries and rural-urban migration within developing countries, which is usually accompanied by environmental and lifestyle changes. In particular, adoption of “Western” dietary patterns, which tend to be high in fat and low in fruits and vegetables, is of concern since diet is a potent contributor to chronic disease risk. However, until recently, the process by which immigrants and rural-urban migrants adopt the dietary practices predominant in their new environments, known as dietary acculturation, has received very little research attention. Dietary acculturation is multidimensional, dynamic, and complex, and varies considerably depending on a variety of personal, cultural, and environmental characteristics. Therefore, to intervene successfully on the negative aspects of dietary acculturation, it is important to understand the process and identify factors that predispose and enable it to occur. The purpose of this article is to provide a practical model for understanding and investigating the effect of dietary acculturation on food and nutrient intake. Thus, this report 1) gives an overview of acculturation, 2) defines dietary acculturation and presents a model for how it occurs, 3) discusses measurement issues around dietary acculturation,4) reviews the literature on dietary acculturation in Korean Americans; 4) suggests a paradigm for acculturation research; and 5) offers some recommendations for future research in this area.

Inflammatory bowel disease (IBD) is a chronic relapsing immune-mediated disease of the intestinal tract. Although its prevalence is reportedly lower in Asia than in Western countries, the rapid increase in the incidence of IBD has drawn attention to its etiology, including genetic susceptibility and environmental factors. Specifically, recent studies concerning dietary treatments and intestinal microbiota suggest that these factors may interact with the immune system, and the imbalance of this relationship may lead to immune dysregulation in IBD. Changes in diet or alterations in the composition of the intestinal microbiota may be associated with the increasing incidence of IBD in Asia. Here, we aim to review recent studies on the role of diet and intestinal microbiota in IBD pathogenesis and the results of the investigations performed to modulate these factors.
