This study was designed to investigate the associations of the percent body fat dietary intake, plasma lipoprotein profile, lipoprotein(a), and plasminogen activator inhibitor-1(PAI-1) concentrations of 1982 Korean subjects(men : 1000 and women : 982) between the ages of 40 and 59 years. The dietary assessment consisted of twenty-four hour dietary records and food frequency questionnaires. The subjects were identified into one of the five rating groups of % body fat : lean, underweight, normal, overweight and obese groups. The biochemical assessment included measurements of plasma total cholesterol(TC), HDL-cholesterol(HDL-C), LDL-cholesterol(LDL-C), triglyceride(TG), lipoprotein(a)(Lp(a)), and PAI-1. With respect to the ratio of percent energy intake of carbohydrate : protein : fat of the normal group of the women was 62% : 17% : 20%, respectively. Women apparently had a higher intake of carbohydrates than men(52% : 17 : 20%) did. There was a linear relationship between energy intake and % body fat in both mean and women(with the exception of the underweight group of women). The relationship of % body fat of men to the protein and fat intake was higher than that of the carbohydrate intake. Of the men in the study, intakes of energy, protein and alcohol were positively correlated to % body fat. In women, energy, carbohydrate and protein intake were positively correlated to % body fat, however, the fat, cholesterol and alcohol intake did not show any correlation to the % body fat in women. This study showed that % body fat was positively correlated with plasma TC, LDL-C, PAI-1 levels, and TG, but the % body fat was negatively correlated with plasma HDL-C level in both men and women. These results indicated that the high energy intake of obese or overweight subjects might contribute to several of the biochemical indices fo coronary heart disease(CHD) risk. In conclusion, increased energy intake is associated with overweight or obesity in middle aged Korean people. There was no relationship between % energy intake of fat and % body fat in the study, in middle-aged Korean men and women. The plasma lipid profile and PAI-1 level thought to be the risk factors of CHD were positively associated with percent body fat in middle aged Korean people.

본 연구는 한국인에게 적합한 단백질 바를 개발하기 위하여 한국과 미국의 시판되고 있는 단백질 바의 라벨 분석을 하였다. 또한 조사한 단백질 바의 단백질 함량과 일일단백질섭취량, 단백질 권장섭취량(DRI), 그리고 단백질 에너지섭취분율(AMDR)과 비교 분석하였다. 단백질 바는 두 나라의 오프라인과 온라인 마켓을 통해 한국의 17개 제품과 미국의 113개 제품을 수집하였고, 영양소 함량과 원재료를 조사하였다. 그 결과, 미국의 단백질 바가 한국의 것에 비해 1회 제공량이 더 많기 때문에 전체적인 영양소의 함량도 높았는데, 특히 100g으로 환산하였을 때 단백질과 나트륨의 함량은 큰 차이로 높았다. 원재료를 통한 단백질 소재를 분석하였을 때, 한국은 분리대두단백(SPI)이, 미국은 분리유청단백(WPI)이 가장 많이 이용되었다. 이는 나라별 식품의 선호와 친숙함에 영향을 받은 것으로 보인다. 결론적으로, 두 나라의 식습관과 단백질 급원에 대한 섭취 및 선호가 다르기 때문에 한국인에게 적합한 단백질 바의 개발이 필요할 것으로 사료되며, 본 연구의 결과는 소비자들이 단백질 바를 선택하는 데 도움을 줄 것이다.

This study was carried to investigate the effects of alcohol intake on the dietary behaviors and nutrient intakes of students in university and was observed characteristics of alcohol drinking, smoking, dietary behaviors, and nutrient intakes of students. The mean of alcohol consumption was 25.7$\pm$21.7g/day and 47.5$\pm$25.8g/day, most high of high alcohol group in the male student than other groups. Smoking were high by increasing of alcohol intake. Most students had dietary problems as skipping meals, eating snack after dinner, high frequency of eating fast and instant food, and eating meals at watching TV or video. The dietary behavior problems in the high alcohol groups showed higher in the female students than the male students. Nutritional knowledge scores was no significantly different by sex and alcohol intake. The intakes of calorie, protein, phosphorous, iron, and niacin in the male students was significantly higher than those of female students. Except for calcium, vitamin $B_2$ and vitamin C, nutrients were satisfied to the level of Recommended Dietary Allowances(RDA). Nutrient intakes was not affected by alcohol intake. But intakes of calorie, protein, phosphorous, and iron were affected by sex and vitamin C intake was affected by sex and alcohol intake.

This study was conducted to find sensitive indicator of food intake and specific food group related to cognitive function and to analyze the pathway among factors affecting food intake and cognitive function of the aged. 179 people over 50 years old were investigated and all the data were analyzed by SPSS 10.0 package. Food frequency was more sensitive indicator to show the relationship between food intake and cognitive function of the aged than the numbers of standard amount of food eaten. Consumption of grains and starch, meat, fish, eggs and beans were strongly related to cognitive function of the aged and intake of vegetables and fruits also have relationship with it. Moreover, the more frequent eating the carbohydrate and the protein, the higher the cognitive level of the aged. Age, education period, income, blood pressure, duration after retirement, frequency of physical activity and BMI were correlated with food intake and cognitive function of the aged. Among them, age and frequency of physical activity were most strongly correlated with food intake, and education period with cognitive function of them. This investigation shows that more stable intake of carbohydrate and protein containing foods need to be supplied to low income aged and the importance of physical activity of the aged must be emphasized with food intake for better life of the aged.

The relationship of nutrients intake and bone mineral density (BMD) was investigated in 285 Korean postmenopausal women (age 40-70 y) consisted of 65 normal women and 159 osteopenia patients who don't have other diagnosed disease. BMD was measured at the spine (vertebrae L2-4) and femur (neck, Ward's triangle and trochanter). Height, weight, body mass index(BMI), lean body mass(LBM), body fat(Bfat) and dietary intakes of animal calcium(animal Ca), protein and phosphorus per 1,000kcaI intake were correlated with BMD of the spine and the femur positively(p<0.05). Women with an animal calcium intake < 315mg/d (mean % animal Ca/total Ca intake > 50%) exhibited significantly lower BMD of the spine and Ward's triangle than that of women with an intake > 315mg/d, p<0.OS. When subjects were grouped by diagnosis into 3 groups (normal, osteopenia and osteoporosis group), animal Ca intake of osteoporosis group (mean animal Ca intake 261mg) was significantly lower than those of the other two groups (mean animal Ca intake 306mg and 297mg, respectively), p < 0.05. These results suggest that balanced nutrients intake and increased animal Ca in the diet is likely to be beneficial in reducing bone loss in postmenopausal women.

This study was conducted to determine the association between dietary calcium intake and biomarkers related to lipid and glucose metabolism and inflammation in Korean patients with type 2 diabetes. Seventy-five subjects (41 males, 34 females) were recruited from a group of patients who had visited the department of endocrine medicine. Data on anthropometric characteristics, clinical indices such as hemoglobin A1c and C-reactive protein (CRP), and dietary nutrient intakes were collected. Subjects were divided into three groups on the basis of their calcium intake [< EAR (below estimated average requirement), EAR-RNI (between EAR and recommended nutrient intake), > RNI (above RNI)]. Average calcium intake of < EAR, EAR-RNI, > RNI groups were $462.7{\pm}18.7$, $649.7{\pm}12.8$, and $895.7{\pm}21.7mg$, respectively. Energy intake was not different among groups but intakes of protein, total and saturated fatty acids were significantly higher in > RNI group than < EAR group. Analysis of covariance revealed that HDL cholesterol level was significantly higher in EAR-RNI group, as compared to < EAR group after adjustment with confounders such as age, sex, BMI and energy intake (p < 0.05). Levels of CRP and homeostasis model assessment 2-insulin resistance (HOMA2-IR) were significantly lower in EAR-RNI group. Total cholesterol level was higher in EAR-RNI and > RNI groups, although within the normal range. Our results suggest that dietary calcium intake may influence the levels of HDL-cholesterol, CRP and HOMA2-IR and subsequently, help management/treatment of type 2 diabetes patients.
