A common belief is that human milk is sterile. However, the development of culture-independent molecular methods, especially Next Generation Sequencing, has revealed that human milk harbors diverse and rich bacterial communities. Although studies aimed at characterizing the microbiota of human milk have produced different findings, Staphylococcus and Streptococcus are presumed to be normal members of the microbiota. Factors that influence variation in the microbiota are unclear; however, the postpartum time, route of delivery, maternal obesity, and health status may be influential. The origin of the microbiota is a hotly debated topic. Human milk bacteria are thought to be introduced through bacterial exposure of the mammary duct during breast feeding and/or the entero-mammary pathway from the maternal gastrointestinal tract. Although the exact mechanism related to the entero-mammary pathway is unknown, it is presumed that bacteria penetrate the intestinal epithelium and then migrate to the mammary gland, dendritic cells, and macrophages. In this review, various relevant studies are introduced.

The purpose of this study was to obtain the nutritional values and objective data of uncooked powdered food (UPF) in korea. We interviewed 27 healthy female subjects aged over 25 years living in the lksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using body fat analyzer. Also we conducted hematological and clinical analysis of blood. The intake of energy, lipid and protein has decreased as people started to take UPF, but the intake of vitamins and minerals has increased. The quality of meals has improved after taking UPF. Due to the energy loss by taking UPF, weight and body fat gradually lessened. Among the lost weight the percentage of the body fat was high and we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening body fat. The most positive change among biochemical changes by taking UPF was decreasing of serum lipid contents. The concentrations of total cholesterol and LDL-cholesterol gradually decreased and decreased intently after 12weeks. Serum HDL-cholesterol gradually increased and serum triglyceride showed gradual decrement. When healthy adult women replaced two of three meals with UPF for 3months, we were able to see some useful changes like decrement of body fat and serum lipid control and during this 3month period, no significant nutritional problems occurred. Complete judgement on UPF may be difficult with these conclusions but if people take a nomal meal once and replenish iron from taking UPF twice a day, we assume that replacing UPF with regular meal not be a problem in nutritional status. If other experiments on the effects of UPF proceed, we believe that those experiments will be very helpful in judging the nutritional value of UPF. (Korean J Nutrition 36(1) : 49-63, 2003)

This study was conducted to evaluate nutritional status of school children by biochemical assessment method. Subjects were 308 school children from 4th to 6th grade living in Bucheon city. Their blood glucose, total protein, albumin, total cholesterol, and triglyceride (TG) concentrations were determined. Mean blood glucose concentration was 77.56 mg/dl and $81.2\%$ of children had normal blood glucose concentration. The average proportion of hypoglycemia was $18.8\%$ among the three grades and prevalence of hypoglycemia in 4th grade school children was highest ($21.8\%$). Mean serum total protein and albumin levels were 7.14g/dl and 4.35g/dl, respectively, and all the subjects except only one were in normal range of total protein and albumin. Mean serum TG and total cholesterol concentrations were 145.82mg/dl and 94.50mg/dl. Serum TG and total cholesterol levels showed same pattern that the concentrations decreased in proportion to grade. Especially, there was significant difference between grades in serum total cholesterol. Furthermore, $11.7\%$ of 4th, $6.8\%$ of 5th, and $2.8\%$ of 6th grade school children have borderline hypertriglycemia or hypertriglycemia, risk factors of obesity or cardiovascular disease later in life. Taken together, there was conflict phenomenon that undernutrition of hypertriglycemia and overnutrition of hypertriglycemia existed together. Therefore, it is needed to develop discriminating and personalized nutritional feeding, counseling, and education program to cover the children of under- or over- nutritional status.

This study was undertaken to investigate the nutrient intake, dietary behavior, perception of body image and iron deficiency of high school adolescent girls. The subjects were 463 high school girls in Inchon. This cross-sectional survey was conducted by questionnaires and data were analysed by SAS program. Nutrient intakes collected from 3 day-retails were analyzed by the Computer Aided Nutritional Analysis Program. The following anthropometric measurements were made on all participants height, weight, body fat (%), skinfold thirkness, subscapular skinfold thickness, mid-upper arm circumference and waist-hip circumference. Blood samples were obtained and analyzed for iron nutritional status. The mean obesity index of rural students were highest among students. However, over 18% of the urban and rural students belonged to the low-weight group. Proportions of skipping meals were most high in urban vocational students and the main reason was lack of time for meal. Most nutrient intakes of the students were below the RDA, in particular calcium, iron, vitamin A and vitamin B$_2$. Most of the students were concerned with body image and weight control. Also they were not satisfied with their body image. The mean fell hemoglobin and transferrin saturation of rural students were lowest among students. The total binding capacity of urban vocational student\ulcorner were Invest among students. Prevalence of iron deficiency was most high in urban general students when judged by Hb, MCV and serum ferritin. In conclusion, this study indicates that nutrient intake in the female high school students was considerably lower than RDA. They should also be notified that severe weight control is very harmful for health. And they had lower self -satisfaction for their body image and undesirable flood habits. Therefore, prefer nutrition education is required to maintain desirable flood habits and improve their iron status in female high school students.

Previous studies have shown that plant-based vegetarian diets, which typically contain a variety of antioxidants and dietary fiber, help reduce the risk of heart disease, diabetes, obesity, and cancer. However, some studies have reported that vegetarian diets can lead to deficiencies in protein and trace minerals compared to non-vegetarian diets. This study was conducted to compare anthropometric measurements, blood parameters, dietary intake, and hair mineral status in long-term vegetarians (MV; moderate vegan, LV; lacto-ovo vegetarian) and non-vegetarians (NV). Thirty MV (12 males, 18 females; mean age, $50.58{\pm}5.05$ years), 15 LV (11 males, four females; mean age, $49.45{\pm}4.97$ years), and 30 NV (15 males, 15 females; mean age, $48.90{\pm}3.62$ years) participated. No significant differences were observed for age, height, weight, or body mass index, but body fat was significant lower in MV and LV males than that in NV males. White blood cell counts of MV, LV, and NV male subjects were significantly different. Dietary intake data showed that plant protein and plant iron intake were significantly higher in MV and LV than those in NV. Animal protein, animal fat, and animal iron intake were significantly higher in NV than those in MV and LV. A hair mineral analysis showed that calcium and iron were higher in the hair of MV and LV than those in NV. Zinc concentration in hair was not significantly different among the groups. The results suggest that vegetarian diets are adequate to sustain mineral status to at least the same degree as that of non-vegetarian diets.

This study was performed to analyze the relationship among sebum hydration content of the skin and nutritional intake, serum antioxidant minerals and antioxidant enzymes, and lipid peroxide concentration in 50 female subjects in their 20s. The skin type was divided into Dry Skin, Mixed Skin, and Oily Skin, and the dry skin group was 14%, the mixed skin group was 56%, and the oily skin group was 30% of all subjects. The average age of the subjects was $20.54{\pm}1.43$ years and BMI was 20.66. The average sebum content in each group was in the order of T-zone>forehead>chin>cheek. In case of the T-zone, a significant difference between the dry skin group and the oily skin group was observed, suggesting that the area is most sensitive to sebum content by skin type. Significant differences were not observed in energy and nutrient intakes by skin type. Serum concentrations of antioxidant minerals such as copper, manganese, zinc and selenium were not significantly different among the groups, but the dry skin group tended to be higher than the oily skin group. Serum catalase was significantly higher in the oily skin group (P < 0.05), and MDA was significantly higher in the mixed skin group (P < 0.05). The hydration of the cheek and serum zinc showed a negative correlation, and the sebum content of the cheek and GPx showed a significant negative correlation. The hydration of the forehead and serum copper showed a significant negative correlation, and the hydration of the forehead and GPx showed a significant positive correlation. The hydration of the chin and serum SOD showed a significant positive correlation. With these results, it is considered that the basic condition of nutritional status can affect the skin health.

Purpose： This study estimated the prevalence of smoking among male and female school employees. This study also correlated key indicators of health with the number of cigarettes consumed per day by the male smokers. The indicators of health included health behavior, blood pressure (mmHg), BMI (kg/m2), diabetes, total cholesterol, GOT, GPT and GTP. Methods： Subjects included 2,640 male and 2,747 female employees working at elementary, middle, and high schools who received a physical check-up at the Seoul School Health Center in 2002. Data was obtained from the physical examinations, questionnaires, and laboratory results. Results： 39.7% of males and 0.4% of females were current smokers. 60% of the male smokers consumed between 10 and 19 cigarettes per day, and39.6% of male smokers had been smoking between 10 and 19 years. Smokers who consumed more than one pack per day had a relatively higher BMI than the non-smokers (24.7 24.1, respectively). However, smokers had lower blood pressure than non-smokers. The mean systolic and diastolic blood pressure of current-smokers were 128.2 and 82.8, respectively, while the values among non-smokers were 129 and 84.5, respectively. The proportion of current smokers with severe obesity (over BMI 30) was 5.0%. This was considerably higher than the 1.3% of severely obese non-smokers. Current-smokers also had mean and abnormal rate of fasting blood glucose, total cholesterol, GOT, GPT, and GTP that were higherthan those of non-smokers. The frequency of red meat consumption, alcohol use, perceived incidents of stress were alsomore frequent in current-smokers than in non-smokers. Exercise frequency was also lower among smokers. In multiple regression after adjusting all possible confounding factors including age, BMI, diet, and drink, the parameter value of fasting blood glucose, cholesterol, GOT, GPT, and GTP increased relative to the level of cigarette consumption. Conclusion： Among school employees, health behavior, and general health status including BMI, total cholesterol, GOT, GPT, GTP, and fasting blood glucose were worse in smokers than in non-smoker.
