The longitudinal changes on human milk volume per day and lactational performance of 23 Korean lacto-ovo-vegetarians(primiparae=11, multiparae=12) from 0.5 to 5 months after parturition have been studied by test weighing method. The human milk volume per day tended to increase during lactation. The mean volume (SD, ml/day) at 0.5, 1, 2, 3, 4, 5 months were 502(102), 692(127), 697(100), 684( 125), 757(52), 703(70), respectively. The overall mean volume was 661$\pm$132ml/day. The peak milk volume during the lactation was observed at most lactating women at the 1st month. The distributions of the individual mean volume during the first 5 months of lactation were found over 750m1(8.7% ), 650-750ml(47.9% ), 550-650m1(2l.7% ), and 450-550ml(2l.7% ) The number of feeding per day was 8.1 ($\pm$1.0) at 0.5 months postpartum, which was consistently decreased. However, the mean volume per feeding was increased from 62($\pm$9.5)ml at 0.5 month to 112($\pm$13.3)ml at 5 months postpartum. The milk volume was correlated with the peak volume. and maternal age. but not with weight before delivery. maternal height and birth weight. No differences of milk volume and lactational performance between facto-ovo-vegetarian and nonvegetarian women were observed. This study suggests that the human milk volume cited in the recommended dietary allowances for Koreitns is over estimated.

Ethyl carbamate (EC) classified as a probable human carcinogen (Group 2A) is naturally formed in alcoholic beverages and fermented foods during fermentation process and/or during storage. The objective of this study was to analyze EC in 34 food items including 14 alcoholic beverages and 20 fermented foods sold in Korea. Each food was collected from 18 supermarkets in 9 metropolitan cities in Korea, and then made into composite. According to food composition and alcohol content, samples were divided into four matrices such as apple juice, milk, Soju (liquor containing about 20% alcohol), and rice porridge. The maximum EC value of $151.06{\mu}g/kg$ was found in Maesilju (liquor made from Maesil and Soju). Whisky and Bokbunjaju (Korean black raspberry wine) contained $9.90{\mu}g/kg$ and $6.30{\mu}g/kg$, respectively. EC was not detected in other alcoholic beverages. Of 20 fermented foods, Japanese-style soy sauce had highest level of $15.59{\mu}g/kg$ and traditional one contained $4.18{\mu}g/kg$. Soybean paste had $1.18{\mu}g/kg$, however, EC was not found in other fermented foods.

Various forms of fermented soybean products are well documented for their health benefits. The efficacy of anti-obesogenic effect of Doenjang, one of the most commonly used seasonings in Korean cuisine, has been reported only in animal models; thus, an evaluation of Doenjang needs to be conducted in human studies. We aimed to test the hypothesis that Doenjang supplementation reduces body weight and changes body composition in overweight adults. A total of 51 overweight adults participated in this study. A group of males with BMI ${\geq}23kg/m^2$ and waist to hip ratio (WHR) ${\geq}$ 0.90, and a group of females with BMI ${\geq}23kg/m^2$ and WHR ${\geq}$ 0.85 were randomly assigned to either a Doenjang supplement (9.9 g dry/day) group or a placebo group for a 12-week randomized, double-blind and placebo-controlled study. Anthropometric parameters, abdominal fat distribution by computerized tomography (CT) and blood components were measured before and after the intervention period. After the 12-week study, the Doenjang supplementation group had significant reductions in body weight (kg), body fat mass (kg) and body fat (%) compared to the placebo group, the supplementation of Doenjang resulted in a significant reduction in visceral fat ($cm^2$), although no changes were observed in total and subcutaneous fat are as ($cm^2$), serum lipid profiles and dietary intakes. The present study demonstrated that daily supplementation of 9.9 g dry/day of Doenjang for 12 weeks reduces body weight and visceral fat in overweight adults.

The aims of this study were to assess the quality of breakfast intake and to examine the relation of breakfast intake to the quality of daily diet in Korean school-aged children. The one day 24-hour recall data from the 2001 National Health and Nutrition Survey were analyzed. The sample of this study consisted of 1,600 children aged 7 to 18 years attending elementary, middle, or high schools. By calorie level of breakfast intake, the children were grouped into Breakfast Skippers (0 kcal; n = 268, 17%), Low Calorie Breakfast Eaters (0 kcal < and < 10% of Estimated Energy Requirement (EER); n = 190, 12%), Moderate Calorie Breakfast Eaters (10% ${\leq}$ and < 25% of EER; n = 861, 54%), or Sufficient Calorie Breakfast Eaters (${\geq}$ 25% of EER; n = 281, 17%). General characteristics including weight status and nutritional quality of breakfast and daily diet were compared among the four groups. The average daily calorie intake of Breakfast Skippers, Low, Moderate, and Sufficient Breakfast Eaters were 1,771 kcal, 1,719 kcal, 1,902 kcal, and 2,349 kcal, respectively; they were 86.3%, 85.9%, 98.0%, and 124.9% of EER, respectively. The percentages of students consuming daily diet with protein, vitamin A, $B_1$, $B_2$, niacin, vitamin C, calcium, phosphorus, or iron less than Estimated Average Requirement decreased in the breakfast groups with the higher calorie level of breakfast intake. The Dietary Variety Score of daily diet significantly increased by increasing the calorie level of breakfast intake. The results indicated the quality of daily diet was positively related to the level of calorie intake from breakfast.

The purpose of the study is to examine the demographic characteristics and socio-psychological factors affecting willingness to take health foods among elderly, which is to get the basic materials of educational program for helping their desirable intake of healthy food. The data were collected from 1,032 elderly subjects and analyzed by SPSS Windows Version 12.0. About forty-one percent of the respondents were taking health foods in the period of survey. The main reason of taking health foods was to maintain and improve their health. The elderly subjects were classified into three groups: (1) a group having willingness to take healthy food, (2) a group having unwillingness to take healthy food, and (3) a group having a wait-and-see attitude. According to the results of chi-square and analysis of one-way variance, there were significant differences among three groups in the variables of 'sex', 'age', 'educational level', 'marriage status', 'monthly allowance', 'eating habit', 'concerns about health', 'self -evaluation of health condition', 'self-evaluation of health condition compared to the same age', 'concerns about health foods', and 'awareness of health foods'. In addition, the result of multinomial logistic regression analysis showed that the factors affecting willingness to take health foods in the future are 'age', 'concerns about health', 'self-evaluation of health condition compared to the same age', 'awareness of health foods', and 'intake of health foods in the period of survey'.

Objectives: This study aimed to analyze the consumption values of fast foods among American consumers and compare the consumption values according to the levels of health consciousness. Methods: An online survey using a self-administered questionnaire was conducted on 351 American consumers. Based on the median health consciousness score (3.83 out of 5 points), the subjects were classified into the low health-conscious group (Low group) and the high health-conscious group (High group). Factor analysis was used to extract factors for the five consumption values (functional, social, emotional, conditional, and epistemic values). The differences in the consumption values between the two groups were analyzed. Results: A total of 14 factors were extracted for the five consumption values and 9 factors among them (convenience, healthiness, and taste in functional values; health-conscious people, young, busy, obese people, low class, and budget restricted people in social values; guilt in emotional values; accidental situations in conditional values) showed significant differences between the two groups. The Low group had a higher perception of the factor of healthiness (P < 0.001) than the High group. The High group had a relatively higher perception of the factors of convenience (P < 0.001), taste (P < 0.001), and guilt (P < 0.001). In addition, the High group perceived the social values of fast foods more negatively. The High group consumed fast foods less frequently than the Low group and perceived their health status and healthiness of eating habits more positively. Conclusions: The results reveal that the health consciousness level significantly influences consumption value perceptions about fast foods in American consumers. Policymakers and marketers can develop effective strategies based on the results of this study.

The coronavirus disease 2019 (COVID-19) pandemic has put focus on the importance of a healthy immune system for recovery from infection and effective response to vaccination. Several nutrients have been under attention because their nutritional statuses showed associations with the incidence or severity of COVID-19 or because they affect several aspects of immune function. Nutritional status, immune function, and viral infection are closely interrelated. Undernutrition impairs immune function, which can lead to increased susceptibility to viral infection, while viral infection itself can result in changes in nutritional status. Here, we review the roles of vitamins A, C, D, and E, and zinc, iron, and selenium in immune function and viral infection and their relevance to COVID-19.
