BACKGROUND/OBJECTIVES: The body composition changes in aging increased the risk of metabolic disorder. Recent dietary studies have increasingly focused on the correlations between dietary patterns and chronic diseases to overcome the limitations of traditional single-nutrient studies because nutrients in food have complex relations that interact. SUBJECTS/METHODS: This study was conducted to classify a dietary pattern among Korean elderly using cluster analysis and to explore the relationships between dietary patterns and body composition changes in Korean elderly aged 65 years or older. The study subjects (n=1,435) were individuals who participated in the Korean National Health Examination and Nutrition Survey (KNHANES) in 2011. RESULTS: There were three dietary patterns derived by cluster analysis in this study: 'Traditional Korean' (37.49% of total population), 'Meat and Alcohol' (19.65%) and 'Westernized Korean' (42.86%). The (1) 'Traditional Korean' pattern was characterized by high consumptions of white rice and low protein, low fat, and low milk products, while (2) 'Westernized Korean' pattern ate a Korean-style diet base with various foods such as noodles, bread, eggs and milk, (3) 'Meat and Alcohol' pattern had high consumptions of meat and alcohol. In body composition changes, compared with the 'Traditional Korean' pattern, the 'Meat & alcohol' pattern was associated with a 50% increased risk of having elevated BMI ($kg/m^2$), 'Westernized Korean' pattern was associated with a 74% increased abnormality of ASM/Wt (kg) by logistics analysis. Most of the Korean adult population continues to follow ether a traditional Korean having beneficial effects for successful aging. However, the 'Traditional Korean' pattern showed low protein intake (0.7 g/kg), calcium intake, and vitamin D intake as well as low of appendicular skeletal muscle mass (ASM (kg)) among 3 groups. CONCLUSIONS: Considering the low ASM, consumption of protein, calcium and vitamin D should be increased for Korean elderly health body composition.
Obesity contributes to an increased risk for chronic diseases, including diabetes, cardiovascular diseases, and certain types of cancer. The prevalence of obesity has increased in Korea. We compared the clinical and dietary characteristics of obese adults (n = 30, 17 men and 13 women, mean age 29.9) to those with a normal weight (n = 15, 8 men and 7 women, mean age 26.5). We determined lipid profiles, fasting blood sugar (FBS), blood pressure, and serum free fatty acid (FFA). Dietary intake was estimated using a food frequency questionnaire (FFQ) and a 3-day dietary record. Exercise patterns and average alcohol intake were determined. The average body mass index was 28.3 kg/$m^2$ in the obese and 21.2 kg/$m^2$ in the normal weight groups. The obese group had significantly higher levels of total cholesterol, LDL cholesterol, and triglycerides, lower levels of HDL cholesterol, and higher blood pressures compared to the normal weight group. FBS was not significantly different between the two groups. The obese group had significantly more subjects with metabolic syndrome (26.7%) compared to the normal weight group (0%). Serum FFA levels tended to be higher in the obese (P = 0.087). No significant difference in caloric intake was observed between the two groups. No differences in carbohydrate, protein, or fat intake between two groups were observed from the FFQ. However, results from the 3-day dietary record showed that the percentage of energy from fat was significantly higher in the obese group. The frequency and amount of exercise did not differ between the two groups. Alcohol consumed per drinking episode was significantly higher in the obese group. These results confirm that excessive weight is associated with disturbances in lipid metabolism in these fairly young and otherwise healthy adults. Dietary factors, including higher fat intake and alcohol consumption, seem to be contributing to the obesity of these subjects.

In current study, we aimed to investigate whether the gentiopicroside (GPS) derived from Gentiana manshurica Kitagawa could block the progression of alcoholic hepatic steatosis to fibrosis induced by chronic ethanol intake. C57BL/6 mice were fed an ethanol-containing Lieber-DeCarli diet for 4 weeks. LX-2 human hepatic stellate cells were treated with GPS 1 h prior to transforming growth factor-β (TGF-β) stimulation, and murine hepatocyte AML12 cells were pretreated by GPS 1 h prior to ethanol treatment. GPS inhibited the expression of type I collagen (collagen I), α-smooth muscle actin (α-SMA) and tissue inhibitor of metal protease 1 in ethanol-fed mouse livers with mild fibrosis. In addition, the imbalanced lipid metabolism induced by chronic ethanol-feeding was ameliorated by GPS pretreatment, characterized by the modulation of lipid accumulation. Consistently, GPS inhibited the expression of collagen I and α-SMA in LX-2 cells stimulated by TGF-β. Inhibition of lipid synthesis and promotion of oxidation by GPS were also confirmed in ethanol-treated AML12 cells. GPS could prevent hepatic steatosis advancing to the inception of a mild fibrosis caused by chronic alcohol exposure, suggesting GPS might be a promising therapy for targeting the early stage of alcoholic liver disease.
Background: Dietary polyunsaturated fatty acids (PUFA) are thought to modify systemic inflammation. The present study aimed to evaluate the relationship between PUFA intake, lung function, and health-related quality of life (HRQoL) in patients with chronic obstructive pulmonary disease (COPD). Methods: In this study, we used the dataset of 6th Korea National Health and Nutrition Examination Survey, in which, a total of 22,948 individuals including 573 participants with a high probability of developing COPD were enrolled. Participants with missing data for the investigated variables were excluded. Linear regression analyses were used to evaluate the association between PUFA intake (omega-3 [N3], omega-6 [N6], and total) with lung function, and HRQoL. HRQoL was determined according to the European Quality of Life-5 Dimensions (EQ-5D). Subgroup analysis of older patients was performed. Age, sex, body mass index, smoking, alcohol, education, residence, total calorie intake, and predicted FEV1% were adjusted in all analyses. Results: Although lung function was not associated with PUFA intake, EQ-5D index was remarkably associated with N3, N6, and total PUFA intake in a dose-dependent manner. This association was more pronounced in elderly COPD patients. Mean levels of N3, N6, and total PUFA intake were significantly higher in patients having better HRQoL with respect to mobility, self-care, and usual activities. Conclusion: Our results suggest that N3, N6, and total PUFA intake are associated with HRQoL in COPD patients. This association may be attributed to mobility, self-care, and usual activities. Further longitudinal study is required to clarify this relationship.
The purpose of this study was to compare the anthropometry, nutrient intakes, dietary - related behaviors and health - related behaviors of male workers that were divided according to their alcohol consumption. The mean height, weight and BMI of all subjects were 172.0$\pm$5.8 cm, 67.8$\pm$9.3 kg and 22.9$\pm$2.6 kg/$m^2$, respectively. The WHR was higher in the heavy drinking group than in the other groups(p<0.01), while the other anthropometric indices were not significantly different among the three groups. The calorie intake was highest(p<0.001) in the heavy drinking group(3,270.4$\pm$686.5 kcal), followed by moderate(2,602.8$\pm$415.8 kcal) drinking group and light drinking group(2,341.5$\pm$449.4 kcal). As alcohol consumption increased, there was a decrease in the percent of energy derived from carbohydrates and lipids, while there was an increase in the percent of energy derived from proteins and alcohol(p<0.001). The heavy and moderate drinking groups had a highers intake of protein compared to the light drinking group, and the heavy drinking group had a higher intake of lipid compared to the light and moderate drinking groups(p<0.01). The intakes of vitamin $B_2$, niacin and phosphorus were lower in the moderate group than the other groups(p<0.01). The average MAR(Mean adequacy ratio) was 1.44$\pm$0.35 and the intake of all nutrients, except for folic acid, was much higher than the Korean RI(Recommended intake). The fruit intake frequency and sleeping hours were the lowest in the heavy drinking group(p<0.05) and the subjects preferred the following order of food products when they drink: meat(42.5%), fish & shellfish(30.0%), fruit & vegetable(22.5%) and others(5.0%) as a side dish. The average rates of smoking and exercise for all the subjects were 77.5% and 67.5%, respectively. The results of this study showed that heavy alcohol drinkers were more prone to abdominal obesity and related chronic degenerative diseases, indicating the need for extensive nutritional education for heavy alcohol drinkers.
Chronic abuse of alcohol can lead to the development of folate deficiency due to inadequate folate intaike, excessive urinary excretion and from effects of ethanol on folate absorption and metabolism . To investigate the effects of alcohol and folate intake on folate metabolism, the rates were raised for 4 and 10 weeks on experimental diets containing 0, 2 8mg folate/kg diet, and were administered 50% ethanol(1.8$m\ell$/kg body weight) three times a week intragastrically. Plasma and tissue folate concentrations were found to be significantly influenced by dietary folate level. In animals fed on folate-deficient diet, concentrations of folate in the plasma, liver and kidney were decreased by 60-89% compared to those on folate-adequate diet, and ther values were further decreased with experimental period. Folate supplementation increased plasma and tissue folate levels significantly by 16-78% compared to those on folate-adequate diet, and the folate levels in the plasma and liver were affected most by the supplementation. Alcohol administration did not seem to influence folate status in the body significantly when animals were raised on folate-deficient diet. However, when rats were fed folate-adequate or folate-supplemented diet, alcohol was shown to decrease plasma and tissue folate concentrations. Among the animals receiving alcohol, folate concentrations in the plasma and tissues were significantly higher when animals fed folate-supplemented diet compared to folate adequate diet. Alcohol seems to exert differential effects on urinary foalte excretion by experimental period it increased urinary folate in the 4-week period, but lowered foalte excretion in the urine when the experimental period was extended to 10 weeks. Alcohol did not seem to influence folate excretion in the feces. These results indicate that folate supplementation might be beneficial in ameliorating the inadequate folate status that might occur with chronic alcoholism.

The critical role of folate in the remethylation pathway for methionine synthesis from homocysteine has been well documented. Hyperhomocysteinemia resulting from inadequate folate nutrition has been implicated in increased incidence of macrovascular diseases, colorectal cancer, neural tube defects, etc. Chronic exposure to ethanol impairs folate nutrition and one-carbon metabolism in the liver, which often results in fatty liver due to a defective remetylation process. This study was carried out to investigate the chronic effects of moderate levels of alcohol and dietary folate on plasma homocysteine levels, and on histopathology and biochemical functions of the liver. Rats were raised on experimental diets with three levels of folate (0, 2, 8 mg/kg diet), and 50% ethanol (1.8 ml/kg body weight) was administered intragastically by intubation tubes three times a week for 10 weeks. Plasma homocysteine concentrations were found to be significantly influenced by dietary folate intake and alcohol administration. Among all treatment groups, plasma homocysteine levels were the highest in the animals receiving a combined treatment of folate deficient diet and alcohol administration. Plasma homocysteine concentrations were negatively correlated with folate concentration in the plasma (p<0.01) and liver (p<0.05). Among alcohol treated rats, increase in plasma homocysteine values due to macrovascular and microvascular fatty changes and spotted necrosis were observed more frequently in folate-deficient animals diet than those on folate-adequate and folate supplemented diets in alcohol-treated rats. These results indicate that folate supplementation above the recommended level might be beneficial in the prevention of alcohol-related hyperhomocysteinemia and abnormal histologic changes in the liver.

Objectives: This study was performed to examine nutrition problems and causes/contributing risk factors. Methods: This study was conducted using data 1,863 adults visited Asan health screening & promotion center located in Seoul, Korea during May to June of 2013. We used Nutrition Care Process Model developed by the International Dietetics & Nutrition Terminology (IDNT). Results: The most frequent nutrition problem in male subjects was excessive alcohol intake. Men in fifties showed the highest rate of excessive alcohol intake among the age groups examined (22.4%). By comparison, the most frequent nutrition problem in women was inadequate protein intake. Women in fifties exhibited the highest rate of inadequate protein intake (22.5%). The most common contributing factors for these observations were a low preference for dairy products followed by high preference for alcohol and a deficit in food-and nutrition-related knowledge, regardless of the sex and age. The most common nutrition problem observed among the group diagnosed with hyperglycemia or hypertriglyceridemia or hyperuricemia or fatty liver was excessive alcohol intake (p < 0.001), whereas the group diagnosed with hyperglycemia or hypercholesterolemia showed significantly higher rate of inappropriate intake of carbohydrate (fructose) compared to the group not diagnosed with such disease conditions (p < 0.05). The group diagnosed with hypercholesterolemia, hyperuricemia and fatty liver showed significantly higher occurrence of inappropriate intake of fat (saturated fat) than the group free of such diseases (p < 0.001). The osteopenia group showed higher rate of inadequate protein intake (p < 0.001) and the fatty liver group with excessive energy intake (p < 0.001). Overall, the results suggest that there is a significant relationship between nutrition problems and health conditions found in groups diagnosed with a diverse array of medical conditions. Conclusions: Therefore, we strongly suggest that dieticians should implement nutrition interventions with people visiting health screening & promotion center based on nutrition problems and the contributing factors diagnosed by dietitions in order to prevent chronic diseases in this population.
