This survey was carried out to obtain the information concerning nutritional status, including factors of food habits and nutrient intake of the long-lived elderly men and women living in Ganghwa-gun. In order to assess the quality of dietary intake among the elderly, a survey was conducted during December 2003 of 103 subjects who were over 85 years of age. Dietary nutrient intake data were obtained through the 24 hr recall method. Chi-square test and t-test were the main data analysis method. Their dietary habits such as three meals a day and a regular meal time have shown that they have generally good eating habits. Average daily calorie intake ($\%$ RDA) was 1233.2 kcal ($68.8\%$) for male and 1215.8 kcal ($75.8\%$) for female which were lower than the Recommended Dietary Allowances (RDA) for Koreans. Energy intake of females got closer to RDA than that of male. Protein intake was 49.3 g for male and 46.9 g for female (which was $82.3\%$ RDA for male and $85.1\%$ RDA for female) for elderly person, the proportion of animal protein to total protein intake were $45.2\%$ for male and $39.0\%$ for female. Average CPF ratio of energy intake for both male and female were 68.7 : 16.1 : 15.2 and 69.6 : 15.4 : 15.0. SFA : MUFA : PUFA ratio of the subject was 0.78 : 1.03 : 1.00 for male and 0.64 : 0.92 : 1.00 for female. Calcium intakes for both males and females were 321.3 mg and 377.2 mg. Vitamin A was the nutrient found to be least sufficient. Mean daily intakes of most of the vitamins and minerals for both males and females were lower than RDA except vitamin C and Zn for female, especially $\%$ RDAs of vitamin A, Ca for male and vitamin A for females were less than $50\%$ of RDA. In conclusion, long-lived elderly in Ganghwa areas did not consume enough nutrients quantitatively as well as qualitatively, especially Ca, Fe, vitamin A, vitamin $B_2$ and vitamin E. These results suggest that nutritional guidelines for older Koreans should focus on the maintenance of adequate energy intake. In addition, selection of foods with high protein and calcium, such as dairy food, should be emphasized, particularly in the long-lived elderly.

전 세계적으로 비만인구의 증가로 인해 경제적 부담이 확대되고 있으며, 그 원인으로 육체적 활동의 감소 및 식이관리의 실패가 손꼽히고 있다. 영양성분 및 칼로리를 기반으로 한 맞춤 식단정보 제공 시스템과는 차별적으로 본 연구는 개인 맞춤형 기능성 식품을 추천하기 위해 비만 관련 SNP (single nucleotide polymorphism) 정보를 활용하였다. 본 연구를 위해 GWAS (Genome-wide association study) 분석을 수행하여 한국인 특이적인 비만 관련 SNP을 발굴하고, 이를 활용하여 유전적 정보를 입력하여 SNP genoype-phenoype 정보에 따른 맞춤 식단옴을 추천하였다. 또한 USDA (The United States Department of Agriculture) 식품 정보를 활용할 수 있도록 식품 통합 Database를 구축하여 식단 추천에 적용하였다. 그 결과, 표현형 정보 BMI (Body Mass Index)는 정상 수치를 가지고 있으나, 비만 관련 SNP 정보를 가지고 있는 샘플은 유전적 비만 위험도를 나타내어 식이관리가 필요하다는 정보를 확인하였으며, 관련 식품 정보를 제공하였다. 따라서 표현형에 따른 비만에 관한 정보와 유전형 정보가 일치하는 것은 아니며, 이는 표현형적 정보만을 이용한 비만 관리 식이 추천에는 한계가 있음을 의미하며 이러한 결과는 비만외 다른 성인병들에도 적용이 필요하며 이를 위해서는 표현형-유전적 통합정보를 기반 한 맞춤식이 추천이 필요함을 나타내었다.

식품 섭취의 다양성과 영양소 섭취 수준간의 관련성을 알아본 결과 다음과 같은 결론을 얻었다. 식품 섭취의 다양성은 대체적으로 열량이나 단백질이 켰으며 비타민 A와 C는 다양성이 적은 것으로 나타났다 식품 섭취의 다양성과 영양소 섭취 수준과의 관련성을 각 영양소의 섭취 수준에 따라 Quartile로 나누어 분석해 본 결과, 영양소의 섭취 수준이 증가함에 따라 대체적으로 섭취한 식품의 수도 증가하는 경향을 보이나 칼슘, 철분, 비타민 $B_1$, 나이아신, 비타민 C는 예외를 가지는 경우도 관찰되었다. Shannon & Weaver's diversity index는 섭취 수준에 따라 다양성의 증가가 일관된 양상을 보이지 않았다. 따라서 영양소 섭취 수준을 측정하는데 지방과 같은 영양소는 섭취한 식품의 종류수가 유용하며 칼슘과 같은 영양소는 Nutrient-specific diet diversity index를 이용하여 측정해야 하는 것으로 보인다. 또한 영양소 섭취 수준에 따라 열량 섭취(예외 : 비타민 A, C)와 식이 영양 밀도도 높았다. 지방과 같은 영양소는 열량 섭취 증가가 그 영양소 섭취 수준의 증가를 더 중요하게 설명해 주며 비타민 A와 같은 영양소는 식이 영양 밀도가 이러한 영양소의 섭취 수준에 더 중요하게 작용하는 것으로 나타났다. 이상의 연구 결과에서 제언하는 바 더 폭 넓은 대상을 중심으로 여러 계절에 걸친 조사의 뒷받침하에 균형식을 이루기 위한 일반적인 식품 섭취의 다양성 정도를 제시할 수 있으리라고 사료된다. 또한 본 연구에서 는 섭취한 식품의 종류수와 Shannon & Weaver's diversity index를 사용하여 식품섭취의 다양성을 분석하였는데 모든 집단 및 모든 영양소에 대해 적용 가능한 신뢰성있는 식품섭취의 다양성을 나타내는 지표에 대한 연구가 계속 이루어져야 할 것이다.

BACKGROUND/OBJECTIVES: Owing to health concerns related to the consumption of traditional snacks high in sugars and fats, much effort has been made to develop functional snacks with low calorie content. In this study, a new recipe for Korean rice cookie, dasik, was developed and its antioxidative, lipid-lowering, and anti-inflammatory effects and related mechanisms were elucidated. The effects were compared with those of traditional rice cake dasik (RCD), the lipid-lowering effect of which is greater than that of traditional western-style cookies. MATERIALS/METHODS: Ginseng-added brown rice dasik (GBRD) was prepared with brown rice flour, fructooligosaccharide, red ginseng extract, and propolis. Mice were grouped (n = 7 per group) into those fed a normal AIN-76 diet, a high-fat diet (HFD), and HFD supplemented with RCD or GBRD. Dasik in the HFD accounted for 7% of the total calories. The lipid, reactive oxygen species, and peroxynitrite levels, and degree of lipid peroxidation in the plasma or liver were determined. The expression levels of proteins involved in lipid metabolism and inflammation, and those of antioxidant enzymes were determined by western blot analysis. RESULTS: The plasma and hepatic total cholesterol concentrations in the GBRD group were significantly decreased via downregulation of sterol regulatory element-binding protein-2 and 3-hydroxy-3-methylglutaryl-CoA reductase (P < 0.05). The hepatic peroxynitrite level was significantly lower, whereas glutathione was higher, in the GBRD group than in the RCD group. Among the antioxidant enzymes, catalase (CAT) and glutathione peroxidase (GPx) were significantly upregulated in the GBRD group (P < 0.05). In addition, nuclear factor-kappaB (NF-${\kappa}B$) expression in the GBRD group was significantly lower than that in the RCD group. CONCLUSIONS: GBRD decreases the plasma and hepatic cholesterol levels by downregulating cholesterol synthesis. This new dasik recipe also improves the antioxidative and anti-inflammatory status in HFD-fed mice via CAT and GPx upregulation and NF-${\kappa}B$ downregulation. These effects were significantly higher than those of RCD.

간편성과 저렴한 가격, 대중매체를 통한 광고의 영향으로 청소년 소비층이 증가하지만, 한편 정크 푸드(junk food)'라는 오명을 지니는 패스트푸드에 대하여 대전에 거주하는 고등학생을 대상으로 섭취 실태를 조사하였다. 섭취빈도 조사 결과 프라이드치킨은 33회/년, 햄버거 29회/년, 피자 17회/년 섭취하고 있는 것으로 나타났다. 햄버거, 피자, 프라이드치킨의 섭취빈도는 BMI 비만도별, 아침과 저녁 식사빈도별, 패스트푸드를 처음 먹었던 시기별 차이가 없었으며, 용돈의 경우 피자와 프라이드치킨은 용돈액수가 많은 사람이 섭취빈도가 높았다. 패스트푸드의 섭취자제 점수는 저체중 또는 비만 학생이 정상 체중의 학생보다 높았으며, 기대체격별 패스트푸드 섭취자제 점수는 차이가 없었다. 결론적으로 비만도, 식사 빈도, 패스트푸드의 처음 섭취 시기는 패스트푸드 섭취빈도와 관련이 없었던 반면, 용돈액수는 많을수록 패스트푸드의 섭취빈도가 높았던 것으로 나타나 용돈액수를 줄이는 것이 패스트푸드의 섭취빈도를 낮추는 효과적인 수단으로 확인되었다.

The purpose of this study was to investigate the obesity and state of dietary intake of 216 young Korean females, and the influence of $\beta$-II, III Adrenergic receptor (AR) gene polymorphism upon obesity and dietary intake. The average weight, height and BMI of the subjects were 160 cm, 54 kg, and 20.9 kg/$m^2$, respectively. The average triceps skinfold thickness, waist circumference, hip circumference and WHR were 21.7mm, 73.1cm, 93.3cm and 0.78, respectively. The results of body composition measurement using bioimpedance method, average body fluid, body protein, mineral mass and body fat were 29.271, 7.22 kg, 6.79 kg and 19.16 kg, respectively. A dietary survey was conducted using 24-hour recall method. Average calorie intake was 1621 ㎉, which is 81% of Korean RDA. We detected 182 (84.3%) Gln27 (QQ) homozygotes and 34 (15.7%) Gln27Glu (QE) heterozygotes for $\beta$-II AR polymorphism. For $\beta$-III AR polymorphism, we detected 163 (75.5%) Trp64 (WW) and 53 (24.5%) Trp 64Arg (WR). The results of comparing of obesity by $\beta$-II AR gene polymorphism, obesity index and BMI of QE type were slightly higher than those of the QQ type. For $\beta$-III AR gene polymorphism, the mean BMI, obesity index, fat mass and percent body fat (%) of the WR type were significantly higher than those of the WW type (p < 0.05). These findings suggest that genetic variability in the human $\beta$-III AR is associated with obesity among young Korean females. We also evaluated the effect of the simultaneous presence of the $\beta$-II AR and $\beta$-III AR polymorphism on obesity. We found that the BMI and obesity index of the mutant type in both $\beta$-II AR and $\beta$-III AR were significantly higher than those of the type that has only one gene mutation or has no mutation (p < 0.05), indicating a synergistic effect of $\beta$-II AR and $\beta$-III AR polymorphism on obesity. No association was found between $\beta$-II Ad or $\beta$-III AR polymorphism and dietary intake.

The purpose of this study was to determine the zinc status of preschool children in Ulsan. The study was conducted in 95 children aged 3 to 6 years by investigating the anthropometric indices and assessing the biochemical analysis. The blood was analysed to assess serum zinc and alkaline phosphatase. And a questionnaire for dietary intakes using 24-hr recall method were performed by mothers of 95 subjects. The dietary intakes of children were analysed to determine the prevalence of inadequate and excessive intakes of zinc with Dietary Reference Intakes for Koreans (KDRIs). WHL (Weight-Length Index) and Kaup index were used to define obesity. The overall prevalence of overweight and obese subjects were 14.7% and 6.3% by WHL, were 15.8% and 13.7% by Kaup index. The mean intakes of zinc by children aged 3${\sim}$5y and 6y were 5.5 ${\pm}$ 1.4 mg/d (75.7% RDA) and 6.7 ${\pm}$ 2.0 mg/d, respectively, that was the level exceeding the estimated average requirement (EAR) and the recommended intake (RI) of Korean Dietary Reference Intakes. Less than 1.3% and 7.9% of children had usual zinc intakes below EAR and RI of KDRIs, respectively. The percentages of children with intakes exceeding the tolerable upper intake level (UL) were 2.6%. The zinc nutritional status by biological assay was found that mean serum zinc and alkaline phosphatase (ALP) of total subjects were 64.0 ${\pm}$ 8.4 ${\mu}$g/dl and 72.8 ${\pm}$ 14.9 U/L, there was not a significant difference between boys and girls. The range of serum zinc level was 45${\sim}$89 ${\mu}$g/dl and children with a low serum zinc concentration by several cut-off points were 18.9${\sim}$55.8%, especially. Serum zinc level was positively correlated to the intakes of calorie, calcium, fiber, iron, zinc, zinc/kg and height (p<0.001). Serum ALP was positively correlated height, weight and WLI. The zinc intake of children aiso showed a positive correlation with height and weight. These results indicate that there were significant correlations between the zinc status and growth of preschool children. Preschool children in Ulsan have dietary zinc intakes that exceed the new DRIs. The present level of intake does not seem to pose a health problem, but if zinc intakes with fortified foods and supplements were considered, the amount of zinc consumed by children may become excessive.
