The purpose of this study was to investigate the regional 야fferences in dietary supplement use and related factors among college students participating in nutritional education programs via the internet. The subjects in this study were 797 college students (male: 518, female: 279). A cross-sectional survey was conducted using a self-administered questionnaire about dietary supplement use, demographic characteristics, health-related lifestyles, nutrient intake, and data were collected via the internet and by mail. Dietary supplements were taken by 82.2% of subjects (males: 76.3%, females: 85.3%). There was a significant regional difference in supplement use (p<0.01). The supplements, used most frequent by male students in the Seoul and Incheon areas were lactic acid beverages and gagogi, in that order. Male students in the Kyunggi area used gagogi and lactic acid beverages in that order. Lactic acid beverages and Chinese medicine were used most frequently by male students in the Chungcheong area. Male students in the Kyungsang area used lactic acid beverages and water-soluble vitamins, in that order. Male students in Seoul and Kyungsang areas showed significantly higher percentage of keep on taking supplements compared to other areas (p<0.05). Both male and female students in the Seoul area had more frequent medical examinations, in comparison to students in other areas (p<0.05). Male students in the Kyungsang and Seoul areas took significantly more calcium (p<0.05) and iron (p<0.05), in comparison to students in other areas. Female students id the Kyunsang area took significantly more Vitamin A, phosphorous and iron (p<0.05), while those in the Seoul area took significantly more Vitamin C (p <0.01) and calcium (p<0.05) . Male students in the Chungcheong area took significantly less seaweed, in comparison to students in other areas (p<0.05) . Male students in the Seoul area had the highest amount of animal fat and oil, while those in the Incheon area ate the lowest amount of animal oil and fat (p<0.05). Female students in the Kyunggi area ate the highest amount of fruit, while those in the Incheon area ate the lowest amount of fruit (p< 0.05) , Female students in the Incheon area ate the highest amount of seaweed, while those in the Kyunggi area ate the lowest amount of seaweed (p<0.01). Therefore, it can be concluded that it is necessary to develop dietary supplements to optimize the nutritional status of college students in different areas of Korea.

Antioxidant vitamin supplementation focuses one's attention on the prevention of age-related diseases. This study was conducted to investigate the antioxidant status and lipid profiles and to look into the antioxidant vitamin supplementation that affects lipid metabolism in 20 elderly non-smoking Korean women (placebo group: n = 6, vitC suppl: n = 7, vitE suppl: n = 7). Age, height, weight, muscle, percent of fat and WHR were not significantly different among the groups, however $\%$ of fat was above $33\%$ and WHR was above 0.9. And blood pressure of the placebo group was 131.7/81.7 (border line hypertension), that of vitamin C supplement was 141.4/87.1 (hypertension) and that of vitamin E supplement was 151.4/92.9 (hypertension). Although nutrient intakes of all groups were poor, antioxidant status (blood vitamins C, E, A, and beta-carotene) and lipid profile (TG, total-cholesterol, VLDL-cholesterol, LDL-cholesterol, HDL-cholesterol) were normal. For nutritional intervention, the vitamin C supplement group received L-ascorbic acid 1,000 mg, and vitamin E supplement group received d-alpha-tocopherol 400IU for 4 weeks, showing the effects of vitamin E supplementation. Response total cholesterol of HDL-cholesterol (T-Chol/HDL) in vitamin E supplement group was significantly decreased from 4.3 to 3.2. And response LDL-cholesterol of HDL-cholesterol (LDL/HDL) in the vitamin E supplement group was also significantly decreased from 2.6 to 1.7. In addition, after the adjustment for plasma lipids (TG, total cholesterol), plasma vitamin A levels in vitamin E supplement group were significantly increased from 7.89 mg/g to 14.91 mg/g. And systolic blood pressure in vitamin E supplement group was significantly reduced. These results suggested that vitamin E supplementation affects the lipid profiles and blood pressure in elderly non-smoking women. So various nutrition programs must be implemented against age-related diseases and further studies are needed regarding sorts and amounts of antioxidant nutrients and supplementation periods.

Our nation is confronted with the situation that the rice, a principal food, short of some essential amino acids, leads to imbalanced meals insufficient in the nutrient of Protein, to bring many difficulties in the elevation of nutritional state in our nation. While. our country has been produced much amounts of Panax Ginseng roots which has a stimulating effects on the metabolism of protein, lipid and nucleic acids in the body. And the leaf and trunk of Panax Ginseng were also produced a considerable amounts as the by-products. Author believe that these by-products (leaf and trunk) of Panax Ginseng might have some components possessing simillar activity with Panax Ginseng root although the quantity and qualify of the functional components may more or less be different. Therefore, this study was demised to observe the supplemental effect of the Panax Ginseng-by-Products on the dietary protein efficiency and nutritional state of rats. The feeds used for this experiment were rice containing 30% barely, fish four, and the leaf, trunk and small root of the Panax Ginseng, and the contents of the general nutrients including protein, lipid and carbohydrate etc. in each feed were analyzed for the combination of each feed. And, being based on analytical values of Protein in food. fish Pour as Protein source was added were rice containing 30% barely to be include 8.6 to 8.7%, 12%, 15% and 18% of protein. Then 2% of the leaf, trunk or small reef of Panax Ginseng was supplemented into each of above protein diet group, ton 16 kinds of diets were Prepared. The male albino rats from a Pure strain, weighing 70g to 80g. were used for experimental animals. They were maintained with coresponding fist for f and 8 weeks, and the growth rate, consumption of diets and protein, efficiency of feed and Protein in animals were determined. The lipids, proteins and cholesterols in serum and liver were also determined quantitatively after they were sacrificed in coresponding term. The results obtained are summarized as follows: 1. Body weigh of diet group containing 8.6 to 8.7%,12%, and 15% of protein are increased remarkably by supplement of 2% of the leaf or small root of Panax Ginseng in comparison with each of controls. But this tendency could not observed in diet group containing 18eA Proteins. 2. Feed efficiency showed same tendency in comparison with changes of gained body weight. Specially, in each of diets containing 8.7%, 12%, 15% and 18% of Proteins, supplement of the leaf of Panax Ginseng showed the better feed efficiency than supplement of the trunk or small root. 3. In feeding group for 8 weeks, protein efficiency showed worst efficiency in diet containing 18% proteins and showed the best efficiency was the diet group containing 12% Proteins. And the efficiency was improved according to supplement of the leaf of Panax Ginseng. 4. Nitrogen contents in serum and liver did not show large differences each other in all diet groups. But contexts of total cholesterol and 1ipid were decreased markedly in diet groups containing 12%, 15% and 18% of proteins in comparison with diet group containing 8.6% to 8.8% of proteins.

The purpose of this study was to provide trustworthy nutritional information by analyzing sugar contents of commercial retort foods. A total of 70 retort food samples were collected, which included curry (n=21), blackbean- sauce (n=16), sauce (n=17), and meat (n=16) from markets in Seoul and Gyeonggi-do. Contents of sugars such as glucose, fructose, sucrose, maltose, and lactose were analyzed in retort foods by using a high performance liquid chromatography-refractive index detector and compared to their assigned values on nutritional information labels. Analyzed sugar contents of curries, black-bean-sauces, sauces, and meats ranged from 1.05~4.63 g/100 g, 1.76~5.16 g/100 g, 0.35~25.44 g/100 g, and 1.98~11.07 g/100 g, respectively. Sauces were found to contain the highest amounts of total sugar. These analysis values were equivalent to the reference values indicated on nutrition labels, which were 40~119.5% for curries, 29~118% for black-bean-sauces, 18~118% for sauces, and 70~119.8% for meats. Therefore, this study provides reliable analytical values for sugar contents in retort foods.

Objectives: This study examined the relationship between the presence of allergic rhinitis and the nutritional intake levels of Korean infants. Methods: The study involved a total of 1,214 infant subjects aged 1~5 months from the 2013~2016 KNHNES (Korea National Health and Nutrition Examination Survey). The Subjects were classified into two groups based on the presence of allergic rhinitis: Non-allergic rhinitis infants (NARI, n=1,088) and allergic rhinitis infants (ARI, n=126). The general characteristics and family history of allergies, nutrient intake status, nutrient supplement intake, and breast milk and baby food start period data of the two groups were compared. All statistical analyses accounted for the complex sampling design effect and sampling weights. Results: The mean age was 0.5 years old in the ARI group compared to the NARI group. In the residence, the rate of urban was higher in ARI. The family history revealed a significant difference between the two groups, particularly those of mothers rather than fathers. The nutrient intake levels were high in energy, phosphorus, sodium, potassium, iron, riboflavin, niacin, and polyunsaturated fatty acids. Breastfeeding was significantly higher in the ARI group than in the NARI group. The baby food start period was 0.3 months earlier in NARI group than in ARI group. The height, body weight, and birth weight were higher in ARI group than NARI group. The result of Odds ratio analysis showed that excess energy, protein, calcium, phosphorus, iron, riboflavin, and niacin intake increases the risk of allergic rhinitis. Conclusions: These results can be used as data to develop nutrition guidelines for allergic rhinitis infants.

The current study examined the effect of quercetin supplements on the lipid-lowering and antioxidant metabolism in ethanol-fed rats. The control $group(E_8)$ received ethanol only diet for 8 wks, whereas the other group$(E_8Q_4)$ received a diet including quercetin supplementation(0.05% wt/wt) for 4 wks while on the ethanol diet for 8wks. The hepatic alcohol dehydrogenase activity was significantly higher in the $E_8Q_4$ group than in the $E_8$ group. Supplementation with quercetin significantly elevated the HDL- cholesterol concentration, the HDL-C/total-C ratio, and lowered the atherogenic index(AI) compared to the $E_8$ group. The hepatic triglyceride and cholesterol contents were significantly lowered by the quercetin supplement compared to those of the control group. The hepatic HMG-CoA reductase and ACAT activities of the $E_8Q_4$ group were significantly lower than those of the $E_8$ group. The overall potential for antioxidant defense was significantly enhanced by the quercetin supplement, as indicated by a decrease in plasma and hepatic TBARS levels. The hepatic GSH-Px and G6PD activities were significantly higher in the $E_8Q_4$ group compared to the $E_8$ group. The current results suggest that dietary quercetin leads to the inhibition of HMG-CoA reductase and ACAT, which in turn lowers cholesterol levels and normalizes antioxidant enzyme activities.

Nonalcoholic fatty liver disease (NAFLD) is recognized one of the leading metabolic diseases globally, and the younger age population with the disease is rapidly growing, especially in developed countries. Since there has been no approved medicine, losing weight is known to be the only best remedy to control or reverse the disease. Recently, the field of microbiome has attracted much attention to offer more practical choices for patients. Here, we provide experimental evidence that Streptococcus thermophilus LM1012 (LM1012), a safe probiotic strain, is effective for improving NAFLD indexes. In the methionine-choline deficient (MCD) diet induced C57BL/6 mouse model, administration of LM1012 promoted marked reductions of aspartate transaminase (23.8%), total bilirubin (27.8%), hydroxycholesterol (64.2%), triglyceride (29.7%) and IL-1β (68.3%) compared to the MCD diet alone group. Also, the histopathological data imply that LM1012 inhibited fat accumulation and inflammation in the liver, which are the key biomarkers for progression of the disease. Together, these findings suggest that human consumption of LM1012 as a healthy nutritional supplement, may be helpful in reducing the risk of liver damages in NAFLD patients.
