Background : Mahuang (Ephedra sinica) has been used widely to treat respiratory disease in traditional medicine for over thousands years. Mahuang preparations contain approximately $0.75{\sim}1%$ ephedrine alkaloids. Recently in North America, the Eephedra alkaloids has aroused a controversy due to its adverse effects in those using whole extracts as "dietary supplements" for weight loss or athletic performance enhancement. Objective : To discuss the need for clinical practice guidelines on the use of Mahuang. Results and Conclusion : It is widely assumed that Mahuang is one of the useful medicines and is safe for human body. Most of scientific literatures support that the safety of Mahuang prescription in common dosage. However, it has been claimed that there were some warnings and apprehensions about the harmfulness of Mahuang as dietary supplements. This article does not negate the fact that it is necessary to pay more attention for use of Mahuang in clinical situations. We assert that the establishment of clinical practice guideline on the use of Mahuang, which is based on scientific materials and consensus, is required in traditional medicine.

This study was performed to assess the relationship between diet quality and general characteristics, stress, exercise habits, and nutritional knowledge score in the postmenopausal women. The data of dietary intakes were obtained using food frequency questionnaires which were collected from 151 postmenopausal women in urban area. Diet quality was assessed by INQ(index of nutritional quality), MAR(mean adequacy ratio), DDS(dietary diversity score), DVS(dietrary variety score), DQI(diet quality index). The results are summarized as follows. The mean age of the subjects was 59.9 years old. The means of height, weight, and BMI were 154.7cm, 57.2kg and 23.9 respectively. The subjects who did not exercise regularly were 70.9% and those who excercised at least once a week were 29.1%. The subjects who had regular meal time were 69.5% and those who ate breakfast regularly were 72.6%. More than 2/3 of subjects had regular eating behavior. Overall dict quality was significantly(p < 0.05) associated with INQ, MAR, DDS, DQI. However, there was no significant association between income level and diet quality. In conclusion, it would be beneficial to provide nutritional education included dietary diversity, dietary variety, dietary guideline, and adequate flood amount, to prevent chronic degenerative disease and maintain healthful life in the postmenopausal women.

Purpose: Despite poor cognitive function in heart failure (HF), few studies have examined cognition and its probable implication in self-care among Korean HF patients. The purposes of this study were (1) to describe cognition in the domains of global, memory, and executive functions, (2) to explore the relationship between cognition and self-care, and (3) to determine the amount of dietary sodium intake among Korean HF patients. Methods: A pilot study was conducted: 7 HF patients (3 men, mean age 68 years) completed face-to-face interviews for neuropsychological tests of cognition and self-care including dietary sodium intake. Results: More than half of the patients had impaired global cognition, memory, or executive function; patients with more severe HF were at higher risk of poor cognitive function. Korean HF patients exhibited poor self-care, with a high dietary sodium intake (5.6 g/day), approximately twice more than the suggested guideline of 2~3 g/day for patients with stable HF. Conclusion: Cognitive dysfunction and inadequate self-care with noncompliance with dietary sodium restriction were evident in Korean HF patients. More studies are warranted that examine the prevalence of cognitive impairment and areas of deficit using neuropsychological tests in a larger sample and that examine how cognition affects self-care and compliance in salt-intake.

The purpose of this study was to investigate the correlation of dietary and serum phospholipid fatty acids composition and serum lipid levels in postmenopausal women. Data about anthropometry, dietary intake, physical activities, serum lipid profile and serum phospholipid fatty acid composition were collected from eighty-five postmenopausal women. The subjects were classified as normocholesterolemia (NC), moderate hypercholesterolemia(MC) and phyperchollesterolemia(HC) according to their serum total cholesterol (TC) levels based on The Guideline for Korean Hyperlipidemia set/published by The Committee for Hyperlipidemia in Korea. The results were as follows. Total energy intake and the ratio of energy intake to energy expenditure were positively related, while dietary fiber intake was negatively related, with serum TC level. Dietary fat intake was positively related with serum LDL-C level. Dietary cholesterol, saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) intake and the ratio of ingested saturated fat and cholesterol to calories (RISCC) were positively related, while the P/S ratio of dietary fat was negatively related, with serum TC and LDL-C levels. Serum phospholipid fatty acids composition was not significantly different among the three groups. SFA of serum phospholipid fatty acids was positively related, while P/S and M/S ratios of serum phospholipid fatiy acids were negatively correlated, with serum TC and LDL-C levels. We recommend that the dietary P/S ratio of postmenopausal women is increased by reducing their dietary SFA intake. With these changes in the diet, serum phospholipid fatty acid composition could be also changed, and serum lipids levels could be improved.

This study investigated whether dietary factors are more influential factor than other health behavior such as drinking, smoking and exercise on abnormal serum cholesterol level inspite of Korean dietary pattern differences compared to Europeans and Americans. A double case control study model has been used for the study design. One model consisted of high blood cholesterol cases and control. the other model consisted of low blood cholesterol cased and controls. 5.398 sedentary male workers who had taken medical examinations at a university hospital were used as the study subjects. Out of the study subjects, 36individuals with high blood cholesterol cases and 30 individuals with low blood cholesterol cases were selected. For the 66 individual control selection, the individual control selection, the individuals matching method was adopted. The food frequency method was used to collect the data for assessment of the dietary factors. A standardized questionnaire was used to investigate other health behavior. logistic regression analysis was employed to measure the relative importance between the factors considered. There were no statistically significant differences observed in nutrients consumption or other health behavior among the low, normal and high blood cholesterol groups, An overmatching effect had been suspected as the cause of those findings. However, the results of logistic regression analysis to identify the factors influencing high serum cholesterol showed that odd ratios of dietary factors such as tocopherol(3.0) and saturated fatty acid(1.6) were higher than I. I of smoking and 1.2 of drinking. Similar results were also observed incases of low serum cholesterol. The above findings imply that although the dietary pattern is quite different from that of Europeans and America, the dietary factor is still a significant factor for abnormal blood cholesterol in Koreans. Therefore, the dietary risk factor identified in high fat consumption populations are still relevant for the relatively healthy Korean as guideline for preventive health practices.

Recent research reported health risks associate with high carbohydrates diets. Objectives of this study were to evaluate in a cross-sectional study if high carbohydrate diet is associated with coronary heart disease(CHD) risk factors: examined blood concnetration of triglyceride(TG), total cholesterol, high density lipoprotein cholesterol(HDL-C), plasma glucose, systolic blood pressure(BP), body mas index(BMI), wasit-hip ratio(WHR) and waist-stature ratio(WSR). Using the most recent US National Health and Nutrition Examination Survey(IIINHANES III) data, the nationally representative US population (3772 men, 4095 women of 25-64 years of age) was divided into low vs. high carbohydrate diet groups(below 40% vs. above 60% energy intake from cab carbohydrates) and compared by the CHD risk factors. Triglyceride was higher(p<0.001) in the high carbohydrate group, whereas high density-lipoprotein cholesterol(HDL-C)was lower(p<0.01) in the high carbohydrate diet group. In plasma glucose, there was no significant differences between high carbohydrate diet and low carbohydrate diet. In adiposity(BMI, WHR and WSR), it also showed no significant differences, After adjustment for age, ethnicity, alcohol and smoking in upper 60%-carbohydrate diet, Odds Ratio of TG and HDL-C were 1.42 and 1.23 in men and 1.22 and 1.17 in women. 50-60% carbohydrate diet was associated with decreased risk of CHD. Dietary guidelines for Koreans recommend 60-70% of total energy from carbohydrate, as Koreans traditionally consumed high carbohydrate diets. In a cross-sectional population of adults, diets containing 55-60% energy from carbohydrate were suggested as a dietary guideline of carbohydrate intake for Koreans.

This study was done to analyze the chronic diseases prevalence and dietary intake status according to the health related quality of life and to identify its significant properties. This study was conducted based on 2906 subjects ranging from 20~64 years old, out of 9704 total subjects from the 4th Korean National Health and Nutrition Survey in 2008. The average quality of life (QL) score was 0.915, where 983 subjects were below the average (low QL group) and 1923 subjects were above (high QL group). In the high QL group, there was more likely to be young, male, and with higher income and education. For high QL group, the self-related health score was high, and the subjective stress level was low. The prevalence of diabetes was significantly higher in the low QL group and anthropometric and biochemical measures were not shown differences between the two groups but waist circumference was significantly higher in the low QL group. The QL score was significantly negative correlated with the waist circumference and the body mass index. As for the recognition rate of Nutrition Guideline, there were no significant differences but high QL group had higher scores in "Eat a variety of foods", "Avoid too much Sodium", and "Enjoy meals and Eating a breakfast". Carbohydrate intake was significantly lower in the high QL group than in low QL group and the high QL group showed higher intake in legumes, meat and poultry, fruits, daily products and beverages. Overall results suggest that increased diabetes prevalence in people with low quality of life might be affected by the diets based on high carbohydrate, increased waist circumference, and lower rate of practice nutritional guideline.

Dyslipidemia is a component of the metabolic syndrome and a risk factor for cardiovascular diseases. Nutrition counseling is important to improve dyslipidemia. The purpose of this study was to evaluate the effectiveness of nutrition counseling in adults with risk factors for dyslipidemia diagnosed by the national health screening program. The nutrition counseling for adults with risk factors for dyslipidemia was carried out at a public health center in Gyeonggi-do. Thirty four patients out of forty five participants in the program completed the nutrition counseling program. The nutrition counseling was provided 3 times during a 12-week period. Individualized nutrition counseling to improve dietary habits was conducted after examining participants' dietary intake through questionnaires about dietary habits and whether they practice dietary guidelines. Data about serum lipid profiles, body composition, nutrition knowledge, the practice of dietary guidelines, and dietary behavior were collected before and after nutrition counseling to evaluate the effectiveness of nutrition counseling. All data were statistically analyzed by SPSS program (Korea ver.18.0) and significant difference was evaluated by paired t-test and ${\chi}^2$-test. Body weight, body fat and WHR were significantly decreased after nutrition counseling. Total-cholesterol, TG, and LDL-cholesterol were significantly decreased but HDL-cholesterol did not show significant changes. Both scores of nutrition knowledge and the practice of dietary guidelines improved significantly (p < 0.001). This study shows that nutrition counseling helps to encourage healthy eating practices and to improve serum lipid profiles of adults with risk factors for dyslipidemia. Overall, results indicated that nutrition counseling resulted in positive changes to lower the reliance on medications. Therefore, nutrition counseling should be considered for the initial treatment of dyslipidemia.

The purpose of this study was to evaluate the prevalence of obesity, dietary habits, and nutritional status by age among low-income women, using data from the fourth Korea National Health and Nutrition Examination Survey (2007~2009). Subjects were 8,356 women aged 20 and over. The subjects were classified into four groups by age. Dietary data from 24-hr recall methods were used to analyze nutritional status. The prevalence of obesity in the 50~64 years age group was significantly higher than those of the other age groups. Among age groups, malnutrition was the highest in the 65-and-over age group. It appears that women in the 20~29 and 65-and-over age groups were the highest nutritional risk. The percentage of carbohydrates in total energy intake was higher and the percentages of protein and fat were lower in the 65-and-over age group than other groups. Frequency of skipping breakfast was lower in women aged 65-and-over, and moderate physical activity significantly decreased with increasing age. Awareness of dietary guidelines was higher in women aged 30~49 years than other groups, whereas it was lower in those aged 65-and-over years. Adherence to dietary guidelines of 'eating a variety of foods from each food group' was significantly lower in women aged 65-and-over years than those of other groups. However adherence to dietary guidelines of 'eating breakfast everyday with a pleasant mind' was significantly lower in women aged 20~29 years than those of other groups. Therefore, this study shows that low income women have various nutritional problems by age group, and we should support a tailored approach to improve their nutritional status.
