  • Milk contains essential nutrients and functional compounds, such as calcium, fat-soluble vitamins A, D, E, and K, carotenoids, bioactive peptides, and sphingolipids. The bioactive molecules from milk are not expensive and have an added advantage of being derived from food. Therefore, they are more stable and have a broader spectrum than that of other chemicals. Bioactive milk components are useful for treating non-digestive tract disorders, such as cancer, cognitive decline, and hypertension. However, the clinical application of certain breast milk ingredients is limited due to the lack of a large-scale production technology. Once the scaled-up production of lactoferrin became possible, clinical applications were devised and evaluated. Similarly, human alpha-lactalbumin made lethal to tumor cells (HAMLET) can be produced on a large scale as a recombinant protein in microorganisms or in transgenic cattle using suitable separation systems. HAMLET can be used to treat human skin papilloma and cancer. Studies on breast milk that explored the clinical applications of the bioactive components of breast milk have spurred the development of translational medicine and breast milk-derived therapeutics. Some breast-milk derived therapeutic agents are already available to clinicians. Many components of breast milk have shown efficacy in pre-clinical studies and have valid clinical evaluations.

  • This retrospective study was designed to evaluate the nutrient contributions of the five meal components of school lunch menus planned for elementary students in two school districts (District A and B) in the Midwestern state of the United States. The 4-week cycle menu was planned for two time periods (Period 1 and Period 2) following guidelines for NuMenus and general menu planning principles. Menu components of planned and served menus for two time periods were analyzed using $Nutri-Kids^{TM}$. No significant differences in the nutrient content of between Periods 1 and 2 were found for District A. District B served significantly more vitamin A and total fat in Period 1 and significantly more calories, iron, vitamin A, protein, and total fat in Period 2 than was planned. The major nutrients provided by the entree component included protein, calories, cholesterol, total fat, saturated fat, and sodium. Milk was an important source of calcium and provided approximately one-third of the total protein and vitamin A in the meal. The vegetable/fruit component was the major source of vitamins A and C. The grain/bread component provided approximately 20% of the carbohydrates among five meal components. The miscellaneous component affected the sodium and fat content of the menus. Menu planners can use the results of this study to enhance their knowledge of the nutrient contributions of each meal component and as inputs for planning menus that meet children's nutritional requirements.

  • This study was performed from March to June 1994 in ANsung Medical Center. We investigated serum components of 78 diabetics in the center, in addition to the nutrient intake status and anthrophometric status of 60 diabetics among them. We separated the latter into 2 groups(ⅰ) less tan 5 years of diabetic duration and ⅱ) more than 6 years of diabetic duration) and analyzed the clinical characteristics of each group. The results are as follows : \circled1 The average ages of male and female subjects were 57.1 and 58.9 years, respectively. The average diabetic duration of male subjects was 4.8 years and that of female subjects was 5.9 . The major occupational field of both male and female subjects was agriculture(33.3%, 36.1%). 50% of male and 75% of female subject's monthly incomes were less than 600, 000 won and 75% of male and 94.4% of female subjects had weekly food expense less than 40, 000 won. The nutrient intake status of the subjects was lower than RDA on the whole. There was no big differences between 2 the male groups of different diabetic duration , but calorie, protein , fat carbohydrate, phosphorus, iron and Vit B$_1$intakes of the above 6 year female group were appearently higher than those of the under 5 year female group (p<0.05). There were different intake tendencies between male and female subjects . For females. the longer the diabetic duration, the less intakes of calorie, protein , fat carbohydrate, phosphorus, iron Vit B$_1$, Vit B$_2$, and niacin were observed. Furthermore, the longer the diabetic duration in females , the more intakes of energy and nutrients, except Vit C were observed. Fasting blood glucose levels were 155mg/dl and 164mg/dl and Postprandial glucose levels were 242mg/dl and 247mg/dl for males and females respectively. Hb of both males and females , and Ht of males met the lower limit of normal status, The serum TG level was higher than normal , so that they seemed to suffer from hyperlipidemia ; their high HbAIC status indicated that the management of diabetes mellitus was poor. The total protein level of female subject was higher when compared with that of males(p<0.05). All subjects blood pressure were higher than normal , and the longer the diabetic duration, the higher was the blood pressure. The serum HDL-cholesterol levels of the above 6 year group male subjects were lower(p<0.05) than those of the under 5 year male group subjects, and the former group's systolic and diastolic blood pressures were higher than those of the latter(p<0.05). Levels of serum total protein, albumin and TG of the above 6 year female group were lower than those of the under 5 year female group(p<0.05). As the diabetic duration was extended, HDL-cholesterol and LDL-cholesterol levels showed a tendency to increase, while Hb, Ht, total protein, albumin, and A/G, which represent the nutrients state of iron and protein, were inclined to decrease. This result showed that serum lipid components went bad. To summarize the results, the longer the diabetic duration, the worse were the male subjects nutrient intake status, but those of the female subjects were good. With respect to serum components and serum lipid subjects Fe, protein, nutrition status and serum lipid component got worse as the diabetic duration was extended , implying the possibility of diabetes mellitus complication grows.

  • Background: We examined changes in red ginseng components after different doses of irradiation were applied. We also evaluated what housewives and teachers know about irradiated food, as well as their perceptions of and attitudes toward it. Materials and Methods: General nutrients and unique components of irradiated ginseng were then analyzed. Education on irradiated foods and red ginseng was provided to teachers and housewives on two occasions, and changes in their behaviors were evaluated via a qualitative survey. Results and Discussion: The ideal radiation dose to reduce the number of bacteria without changing the unique components of red ginseng is 7.5 kGy. Notably, after educational seminars on this topic, consumers' knowledge, attitudes toward, and perceptions of irradiated ginseng compared to non-irradiated red ginseng changed significantly. Conclusion: It is necessary to provide consumers with information on irradiated foods to promote the growth of the domestic food industry, and to improve public knowledge of the safety and effects associated with the irradiation of food.

  • This study aimed at investigating correlation of nutrients intake and serum lipids in middle-aged korean male and female workers. One hundred sixty eight(male ;105, female ;63) for adult aged 30-59yr(average age male ;36.5yr, female ;44.5yr) were selected as subjects during 2 months, from April to May, 1996. Nutrients intake status was investigated by questionnaire, 24-hour recall method. Antropometric assessments, serum lipids and blood pressure of the subjects were investigated. The results as follows: 1. Nutrients intake status ; male was superior to female. Vitamin A intakes of 40-49yr group were inferior to other group but amounts of intake were above Korean RDA(recommended dietary allowances), Intakes of calcium and vitamin C of 30-39yr and over 50yr group in female were below Korean RDA. In overweights group of male and underweight group of female, most nutrients intake were increased than other groups. 2. Antropometric assessments ; female was higher than male in BMI (body mass index). All subjects increasingly with age were increased in BMI. 3. Blood components were above normal range in triglyceride in both sexes and all subjects increasingly with age were increased In level of serum lipids and blood pressure, especially in male's forty and in female's fifty were higher than other groups In serum lipids and blood pressure. In overweights group, serum lipids and blood pressure had a significantly($\alpha$=0.05) increasing tendency in both sexes. 4. Serum lipids and connected factors; atherogenic index correlated positively with triglyceride, total-chol(total cholesterol), LDL-chol(low density-lipoprotein cholesterol) and negatively with HDL-chol(high-density-lipoprotein cholesterol) significantly(P<0.001). Systolic blood pressure correlated positively with total-chol and diastolic blood pressure correlated positively with total-chol, LDL-chol significantly(P<0.05). 5. Serum lipids and nutrients intake status: energy correlated positively(P<0.05) with BMI, dietary fiber correlated positively with LDL-chol(P<0.05), calcium correlated positively with triglyceride, atherogenic index and dietary fiber correlated negatively with BMI in male significantly(P<0.05). Triglyceride correlated positively with vitamin C and phosphorus correlated negatively with BMI in female significantly(P<0.05). Above results, in male's forty and in female's fifty were liable to variation in terms of serum lipids and blood pressure. As increasing triglyceride, total-chol, LDL-chol and decreasing HDL-chol Increased atherogenic index that suggest increasing risk of atherosclerosis. But, this point will be considered more subdivided study.

  • This study was carried out to investigate the clinical characteristics of 78 diabetics by body fat distribution pattern. It was based on the survey of nutritional status, anthropometric measurements and serum components of the patients. The results were as follows: the average ages of male and female subjects were 57.1, and that of female subjects was 58.9, respectively. The average diabetic durations of male and female subjects were 4.8 and 5.9 years, respectively. In male, the ratio of upper body obese subject was 62.5% and the lower body obese subjects was 37.5%, while those of female were 69.4% and 30.6%, respectively. In nutrient intake state, there was no significant difference between male and female subjects, but calory intake of upper body obese subjects was difference between male and female subjects, but calory intake of upper body obese subjects was tend to be higher in both male and female subjects. among the three major nutrients/calory ratio, protein/calory ratio was significantly lower in the male upper body obese subjects than in the male lower body obese subjects. Since weight, circumference of arm and waist, waist hip ratio(WHR) of both male and female subjects, body muscle mass(BMM) of male subjects and body mass index (BMI) of female subjects were significantly higher in upper body obese group, upper body obese subjects represented ore fat than lower body obese subjects. In male subjects, hemoglobin(Hb), A/G of upper body obese subjects were lower than the standard value, but there was no significant difference in the serum components between two subjects. In female subjects, Hb and A/G of lower body obese subjects were lower than those of the normal subjects, but Hb and Ht of upper body obese subjects were significantly higher than those of the lower body obese subjects.
