Safflower (Carthamus tinctorius L.) seeds have long been clinically used in Korea to promote bone formation and prevent osteoporosis. In addition, the safflower buds (SB) were found to have more useful functional ingredients than safflower seed. Thus, we investigated the preventive effects of SB diet in ovariectomized (OVX) rats. The rats were divided into five groups; sham operated group, OVX alone group, OVX plus 17β-estradiol (E₂ 10 μg/kg, i.p.) and OVX plus SB diet feeding group (0.3% or 1%). Feeding of SB diet (0.3% or 3%) to OVX rats markedly increased trabecular formation in femur compared to OVX rats. Feeding of SB diet (0.3% or 3%) to OVX rats also decreased TRAP activity compared to OVX rats. These results suggest that SB diets have bone sparing effects by the decrease of osteoclast activity. We also observed that OVX rats fed with SB diet (0.3% or 3%) exhibited the decrease of calcium and phosphorus in serum compared to OVX-induced rats. Therefore, SB may be beneficial for the patients of osteoporosis, especially in postmenopausal women.

In Korea, nutritional services have not been included in the periodic medical examinations for employees. Naturally, the practice of individual dietary treatment, or nutrition education, has not yet been implemented, specifically for employees who are expected to encounter health problems. This study was designed to evaluate the necessity and development of nutritional consultations during medical examinations of employees and of worksite nutrition programs. One hundred and five employees from three companies were chosen as subjects for this study. As a result, the average intake of nutrients were found to be sufficient for male employees but female employees were found to be deficient in their intake of total calories, calcium, iron, vitamins A and $B_2$. Also, most of employees did not recognize their own blood cholesterol levels, blood pressure, or blood sugar level. Many employees thought that they needed nutritional consultation during periodic medical examinations and during worksite nutrition programs that also include programs for the whole family. According to the results, clinics for weight control were urgently demanded among several nutrition programs. It should be noted that weight problems, high blood cholesterol levels, diabetes, and other health problems were frequently found in companies whose employees had relatively minimal knowledge about nutrition information. In an effort to prevent disease, the worksite nutrition programs and other nutritional services for employees are critical. This study, therefore, suggests to include nutritional services in medical examinations and to develop efficient worksite nutrition programs.

This study was conducted to investigate the anthropometric data, serum profiles, food intakes frequency, and nutrient intakes of women aged 30-49 years. The subjects were divided into two groups: drinking group and non-drinking group. For the study, we obtained data for analysis from the combined 2008-2015 Korean National Health and Nutrition Examination Survey (KNHANES). Height and weight were 159.2 cm and 58.1 kg in the drinking group as well as 158.1 cm and 57.7 kg in the non-drinking group, respectively. Obesity percentage in the two groups were 22.5% and 24.8%, respectively. HDL-cholesterol (P<0.001) and Vitamin D (P=0.0248) levels in the drinking group were significantly higher than those of the non-drinking group. In the drinking group, rates of hypertension, myocardial infarction, and diabetes were significantly lower than those of the non-drinking group. Food and nutrient intakes, including energy, water, protein, fat, retinol, thiamin, riboflavin, and niacin, in the drinking group were significantly higher than those of the non-drinking group. In the two groups, energy, water, fiber, calcium, and potassium intakes were low while Na intakes were extremely high considering KDRIs (Dietary Reference Intakes for Koreans). The mean adequacy ratio (MAR) in the two groups was not significant.

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 this study was to investigate effects of the developed nutrition education program focused on individual daily energy requirements and food exchange units using Food Exchange System for diabetes mellitus at a community health center. Developed the nutrition education program, four weeks' nutrition education including provided twice individual meal as diet therapy (2 hour/lesson/week, 4 week), was provided to 20 diabetic elderly (12 male, 8 female, 50-75 yrs): 1st lesson "Introduction: management of diabetes mellitus", 2nd lesson "6 Food groups and sources of 6 food groups", 3rd lesson "Individual daily energy requirements and food exchange units", and 4th lesson "Food choice for diabetes mellitus". For effects' analysis of the developed program, we assessed the changes in anthropometric characteristics; biochemical characteristics and nutrient intakes using 24 hr recall method. Effects of the developed nutrition education program were as follows: weight was significantly decreased, blood urea nitrogen (BUN) and glycosylated hemoglobin (HbA1c) were significantly decreased, and distribution of subjects in BUN and HbA1c was significantly changed. In protein : fat : carbohydrate (PFC) ratio, it was significantly changed from 15.98 : 16.30 : 66.69 to 17.51 : 18.94 : 64.10. In evaluation of nutrient intakes by Dietary Reference Intakes for Koreans (KDRI), protein, fiber, fat, vitamin E, niacin, folic acid, calcium and zinc were shown significantly positive changes in distribution of subjects according to intake level. The index of nutrition quality (INQ), nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) were significantly increased. In conclusion, the developed 4 weeks' nutrition education program focused on individual daily energy requirements and food exchange units using Food Exchange System for diabetes mellitus at community health center may improve the symptom of diabetes mellitus.

The aim of this study was to investigate the association dining-out frequency, nutritional intake level and health risk factors related to metabolic syndrome among Korean women. The data in this study were obtained from the Korean National Health and Nutrition Examination Survey in 2013 (KNHANES VI). Sample of Korean women (n=3,413), aged over 20 with biochemical, dietary and health screening data, was divided into three groups according to dining-out frequency; "Rarely" (< 1 time / week), "Occasionally" (2~4 times / week) and "Frequently" (${\geq}5times/week$). The results showed that there were significantly different intake levels in energy, water, protein, fat, calcium, sodium and vitamin A according to the dining-out frequency. Each dining-out frequency group was significantly associated to obesity and Low HDL Cholesterolemia. In conclusion, this study found significant association between dining-out frequency, nutritional intake and health risk factors among Korean women. Further studies are necessary to examine subdividing into age and dining-out frequency and health risk factors related to metabolic syndrome among Korean.

In other to investigate the hypolipidemic effect of dry edible leaves on serum lipids, four kinds of powdered leaves(persimmom, mulberry, perilla, and soy bean) were added to experimental diets at the levels of 5%(w/w). The diets were fed to 30 male Sprague-Dawley rats, aged 4 weeks and weighing 60$\pm$5g, for 3 weeks. Food intake was the largest in Group 1(control), with 5% of cellulose powder, while food efficiency was the highest in Group 2(persimmon). Total cholesterol level in serum was lower in Group 5(soybean) and Group 4(perilla) than the other groups. In comparison with Group 1, HDL-cholesterol level was very high in Group 4 and atherogenic index was low in Groups 4 and 5. Free cholesterol level was the highest in Group 2, and was the lowest in Group 1. Both LDL and LDL-cholesterol levels were the lowest in Group 1, while they were very high in Groups 2 and 3(mulberry). Triglyceride level was the lowest in Group 4, and the highest in Group 1. Except Group 3, all groups had lower phospholipid level than Group 1. Compared with Group 1, calcium level in serum was low in Groups 3, 4 and 5, magenesium level was low in Groups 2, 3 and 5, phosphate level was high in Group 4, and iron level was exceptionally low in Groups 4 and 5. In conclusion, Group 4(perilla) and Group 5 (soybean) showed a favorable effect in atherogenic index and serum levels of various lipids.

The purpose of this study is to analyze the factors associated with health and diet by nutritional status. The subjects were the children aged 2 to 6. Physicians and nurses measured children's anthropometries and examined their blood and urine. Interviewers questioned children's food habits to their mothers. 24 hour recall was done for children with their mother. The nutritional status was classified to 'underweight', 'normal weight' and 'overweight' by weight for height(median±1 S.D.) of the reference population. The number of subjects in each group(under, normal, over) was 25, 130 and 49. Factors including anthropometry and hemoglobin concentration were not significantly dif ferent by the nutritional status. The birth weight of children was correlated positively to mothers' BMI. Z scores of weight for height were related to the birth weight positively by the analysis of variance. The children of the underweight group used nutritional supplements more frequently than those of normal and overweight group. The nutrient intakes of normal weight group were higher than those of low and overweight group. Particularly, the intakes of energy, carbohydrate and calcium were significantly high among the groups. In terms of number of foods, food groups and dishes consumed per day, the children of the normal weight group ate more diversely than other groups but the differences were not significant. In conclusion, the children of normal weight group had similar characteristics with other groups but had more desirable dietary intakes than other groups in this study. Because the diet of children may be different by the nutritional status, nutrition education for children should be conducted according to the characteristics of each group's diet.

This research was carried out to investigate the health condition, eating behavior and nutritional status of female high school students. The survey was conducted from July 5 to July 18, 1996 with 524 first grade students(15 to 17 years old) of H girl's high school using the questionnaire method. The levels of depression and anxiety were measured by CED-S and Spielburger's STAI-S, respectively. In addition, nutrient intakes were estimated by Convenience Method. The results of this study are as follows: 1. The mean depression and anxiety scores of the subjects were 22.23 and 26.00, respectively. The proportion of subjects with normal weight(BM) was 72.1%. The perceived health condition of subjects was moderate and 15.1% of subjects were anemic. The subjectiv health symptoms were feeling drowsy, tired eyesight, getting tired easily, catching cold frequently and frequent headache. 2. The irregularity of breakfast was high in the subjects. The problems of the eating behavior were irregular meals, unbalanced diets, excessive meals, skipping meals and food prejudice. Forty-nine percent of subjects had good eating behaviors. 3. The mean energy intake of subjects was 1717Kcal. The proportion of energy derived from carbohydrates, proteins and fats were 62.70%, 13.89% and 23.42%, respectively. The subjects consumed 59.59g of protein, 13.07mg iron, 637.49mg calcium, 553.64 R.E. vitamin A, 0.94mg vitamin B1, 1.08mg vitamin B2, 15.15mg niacin and 49.59mg vitamin C, respectively. Except niacin, other nutrient intakes were less than the Korean recommended dietary allowances(RDA), especially, iron. 4. Mother's occupation, subject's pocket money and perceived health condition were negatively correlated with eating behavior, And the depression and anxiety of subjects showed wrong eating behaviors. The effects of socioeconomic variables, depression, anxiety and perceived health condition on the nutrient intake were different depending on the kind of nutrient. The nutrient intakes differed significantly among the group of different eating behavior. The eating behavior was significantly correlated with the nutrient intake.

The purpose of this study was to investigate the acid tolerance, bile acid tolerance, and fermentation activity of lactic acid bacteria isolated from Kimchi in the presence of hydrolysates of whey protein concentrate. Kimchi isolates DK109, DK119, DK121, DK128, DK211, DK212, and DK215, which were identified as Lactobacillus sp., and L. casei DK128 showed the highest acid and bile acid tolerance. To produce whey hydrolysates, enzymes were added to a 10% (w/v) whey protein concentrate (WPC) solution at 1:50 (w/v, protein). The viabilities of the DK strains were determined in the presence of low pH and bile salts. Then, yogurt was produced via fermentation with L. casei DK128, an isolate from Kimchi, in the presence of the following additives: CPP, WPC, and WPC hydrolysates (WPCH) generated by alcalase (A) or neutrase (N). The produced yogurts were subjected to various analyses, including viable cell counts (CFU/mL), pH, titratable activity, and sensory testing. After 8 h of fermentation, the pH and titratable activity values of all test samples were 4.2 and 0.9, respectively. The viable counts of LAB were $3.49{\times}10^8$, $5.72{\times}10^8$, $7.01{\times}10^8$, and $6.97{\times}10^8$, for the Control, CPP, A, and N samples, respectively. These results suggest that whey proteins have potential as dietary supplements in functional foods and that WPCH could be used in yogurt as a low-cost alternative to CPP.
