The aim of this study was to evaluate effects of modified glucomannan ($Mycosorb^{TM}$) on the antioxidant profile of egg yolk and tissues of newly hatched quail after aurofusarin inclusion in the maternal diet. Fifty-four 45 day-old Japanese quail were divided into three groups and were fed a corn-soya diet balanced in all nutrients ad libitum. The diet of the experimental quail was supplemented with aurofusarin at the level of 26.4 mg/kg feed in the form of Fusarium graminearum culture enriched with aurofusarin or with aurofusarin plus $Mycosorb^{TM}$ at 1 g/kg feed. Eggs obtained after 8 weeks of feeding were analysed and incubated in standard conditions of $37.5^{\circ}C$/55% RH. Samples of quail tissues were collected from newly hatched quail. The main carotenoids, retinol, retinyl esters and malondialdehyde were analysed by HPLC-based methods. Inclusion of aurofusarin in the maternal diet was associated with decreased carotenoid and vitamin A concentrations in egg yolk and liver of newly-hatched quail. Furthermore, lipid peroxidation in quail tissues was enhanced. Inclusion of modified glucomannan ($Mycosorb^{TM}$) in the toxin-contaminated diet provided a significant protective effect against changes in antioxidant composition in the egg yolk and liver. It is suggested that a combination of mycotoxin adsorbents and natural antioxidants could be the next step in counteracting mycotoxins in animal feed.

The purpose of this study is designing a daily diet according to the nutrition by using genetic algorithms. The ratio of the amount of nutrients needed for each individual is different. For example, people who want to lose, maintain or gain the weight need different amount of nutrition and ratio. In addition, the nutrition should be different between the age groups such as child, youth and senior. So, it is important for each person to individualize content of nutrition that they need not the nutritional standard table. Thus, in this study, by using the genetic algorithm, our study is about the program that can make a daily diet which is optimized for individual. The program has the information of main dish, soup and side dish that we entered before. And person who uses the program can see the daily diet which is optimized related by nutrition what the person entered before. Generally, it is really difficult to design a meal by considering all of the nutrition at home because there are a lot of things to be considered. Therefore, the goal of our study is to make the program what can make a balanced daily diet at home.

Effects of alchohol and fat content in a balanced diet on chemical composition and morphology of liver were investigated in growing rats. Fourth eight male rats of Sprague-Dawley strain weighing about 160g were divided into 4 groups ; high fat diet group, alcohol-administered high fat diet group, low fat diet group and alcohol-administered high fat diet group, low fat diet group and alcohol-administered low fat diet group. High and low fat diets supplied 30% and 12%, respectively, of total calorie intake from fat, and alcohol was given by adding ethanol in drinking waster at 10%. Diets contained adequate amounts of all nutrients required for rats, including lipotrpoic agents(choline and methionine) to minimize effects of factors other than alcohol on liver damage. Ratios of liver weight to body weight were statistically different among groups. Liver/dody weight ratios alcohol-administered rats were significantly higher than those of non-alcohol groups after 6 weeks treatment. Although total lipid and triglyceride per gram liver were increased in alcohol-administered rats, especially low fat diet fed rats, the values were not significantly different. Opticmicroscopical observation revealed increase in cell size and no change in morphology of liver. Examination of hepatocytes by electron microscopy showed that fat droplets were observed in all groups but enlarged in the alcohol-administered low fat diet fed rat. Contents of protein, cholesterol and phospholipid were not affected by alcohol consumption. The level of lipid peroxide was significantly lower in the livers of alcohol-administered rats than in the livers of non-alcohol groups. The results of this study indicate that even moderate alcohol drinking and dietary fat content did not affect any significant change in composition and morphology of liver until 6 week treatment but that even moderate alcohol drinking caused some signs of steatosis of liver.

The aim of this study is to survey the eating habits and nutritional knowledge of children in Pusan, with a view to uncovering problems and their underlying causes and cultivating desirable dietary habit and nutrition for children. Three hundred and fifty six elementary school students were asked questions about their eating habits and nutritional knowledge as well as general information about their personal characteristics. The results showed: 1. Only 53.5% of the subjects had breakfast every day. Seventy-six percent of the subjects had dinner every day. Only 40% of the children took meals and talked with family at both breakfast and dinner. Thus there was little opportunity for dietary guidance by parents. 2. About half of the subjects answered that their appetite decreased after eating snack foods between meals. A third of the subjects liked the baked goods as snacks. Because of their high sugar and fat content, they can damage children's health, resulting in child diabetes and tooth decay. For this reason, careful education is necessary to allow children to be able to select snack foods that are appropriate in kind and quantity. 3. About 85% of the subjects had an unbalanced diet. Therefore systematic nutrition education at school is necessary to instill in children the value of balanced diet. 4. Children preferred rice to other cereals as a staple food. They disliked kimchi, seasoned and blanched foods and salads as subsidiary foods. It is therefore necessary to teach children systematically the nutritional advantage of cereals and vegetables and to heighten their awareness of Korean food culture. 5. Children had a low level of nutritional knowledge. The knowledge of specific nutrients was lower than that of foods. In conclusion, systematical educational programs need to be developed at elementary school. These should include information about achieving a balanced diet, good eating habit, meal management and Korean dietary culture. Nutritional education at home must be emphasized.

This study was conducted to assess the nutrient intake and diet quality of college students in Seoul. Dietary survery data were obtained by 24-hour recall method from 774 students, 553 males and 191 females. Mean daily intake of energy was 2,480kcal with 56.4% of energy intake from carbohydrate, 14.6% from protein, and 25.5% from fat. Percentage of fat was higher than mean values of National Nutrition Survey(NNS), adults in rural area or younger students in previous studies. Mean daily intakes of calcium and vitamin A did not meet RDA levels in both sexes and intake of iron in females was insufficient to meet RDA level. The percentage of animal food to total food intake was 25% and consumption of meat, beverage and milk group was higher than those of National Nutrition Survey(NNS). When the consumption of 5 major food groups(grain, meat, milk, fruit, vegetable) were evaluated, 22% of students consumed all 5 groups and 47% consumed 4 groups, which show more balanced food group intake than adults in rural area. Food groups which were omitted frequently were milk and fruit. These results show that college students in Seoul consume better diet than subjects of National Nutrition Survey(NNS) or adults in rural area. However, high fat intake, low calcium and vitamin A intake and low iron level in women were observed. Majority(78%) of students had at least one food group omitted in their diet. Appropriate nutrition education may help to improve the quality of diet in these students.

This study was designed to determine changes of nutritional status, diabetic indices and serum lipid composition in non-insulin dependent diabetes mellitus patients during intake of diabetic-oriented convenience food prepared from 7 medicinal plants and chicken. We conducted dietary, anthropometric and biochemical assessments before and after the intake of diabetic oriented food. Once a day, in the study, their normal lunch was replaced by the diabetic-oriented convenience food diet for 30 consecutive days. It was found that the nutrients of the diet were well-balanced, and the intake levels nearly approached those of the RDA. Obesity rate, body fat, and body weight were significantly lower than those of a normal diet. The average fasting blood glucose significantly decreased while the insulin level significantly increased after the intake of diabetic meal. Also the total serum cholesterol and triglyceride levels significantly decreased. The above results indicate that diabetic-oriented convenience food prepared from 7 medicinal plants and chicken may be used as a diet regime fer controlling the diabetes mellitus on a regular basis.

This survey was conducted to investigate the dietary behavior and health status of Buddhist nuns. In this study, 100 Buddhist nuns in Seoul were selected. The dietary survey was focused on the diet in winter. The age distribution was as follows; 24% of the subjects were in their 20s, 45% in their 30s, 23% in their 40s, and 8% in their 50's and over, respectively. The percentage of the subjects living in temples close to the downtown area was 77% and the rest resided in areas remote to the downtown area. Over fifty percent of the subjects were satisfied with their diet at temple. And 59% of the subjects were eating a snack more than once a day. The snacks included fruits (60%), raditional tea (20%), coffee (9%), bread and cookies (4%), md rice cakes (3%), etc. Among food groups, the intake of green-vegetables and fruits were the highest and intake of milk and bean products were low which may cause calcium and protein deficiency. Most of the subjects believed that their health conditions were average or above average. About 50% of subjects didn't exercise at all. The frequencies of gastro-intestinal diseases and anemia were extremely high. About 50% of subjects took some form of medicine. To improve their health and nutritional status, it is required that they practice a good dietary behavior, maintain a balanced diet, and exercise regularly.

Metabolic bone diseases are serious health issues worldwide, since several million individuals over the age of 50 are at risk of bone damage and should be worried about their bone health. One in every two women and one in every four men will break a bone during their lifetime due to a metabolic bone disease. Early detection, raising bone health awareness, and maintaining a balanced healthy diet may reduce the risk of skeletal fractures caused by metabolic bone diseases. This review compiles information on the most common metabolic bone diseases (osteoporosis, primary hyperparathyroidism, osteomalacia, and fluorosis disease) seen in the global population, including their symptoms, mechanisms, and causes, as well as discussing their prevention and the development of new drugs for treatment. A large amount of research literature suggests that balanced nutrition and balanced periodic supplementation of calcium, phosphate, and vitamin D can improve re-absorption and the regrowth of bones, and inhibit the formation of skeletal fractures, except in the case of hereditary bone diseases. Meanwhile, new and improved drug formulations, such as raloxifene, teriparatide, sclerostin, denosumab, and abaloparatide, have been successfully developed and administered as treatments for metabolic bone diseases, while others (romososumab and odanacatib) are in various stages of clinical trials.

The objectives of this study were to classify the types of elderly households and to compare the characteristics of their dietary lifestyle. Panel data surveyed by Korea Rural Economic Institute (KREI) for Food Purchase Attitudes over three years (2019 - 2021) were utilized for the analysis. Through a factor analysis, five common factors were extracted out of 19 basic variables related to dietary style, which indicate two kinds of consumer competency index (safe diet, traditional diet) and three kinds of purchase frequency (healthy food, meat & fish, fresh seafood). Applying the cluster analysis method, by using socioeconomic variables along the five common factors, elderly households aged 60 or older were grouped into four types. As a result, Type 1 elderly households accounted for 50.8%, Type 2 for 16.2%, Type 3 for 27.8%, and Type 4 for 5.2% out of all 870 elderly households. Type 1 is characterized as a low-income vulnerable class with a poor diet, Type 2 as a middle-income class with a healthy food-oriented diet, whereas Type 3 was classified as a middle-income class with a meat-oriented diet, and Type 4 as a high-income class with diverse dietary culture. It is necessary to expand the agri-food voucher pilot project to the entire country and also increase the monthly subsidy for the Type 1 elderly households. Implementing community kitchen projects for elderly single-person households, promoting senior internships by providing incentives to companies that employ retirees, the provision of education by local governments on a safe and balanced diet for Types 2 and 3, and the promotion of an elderly-friendly social environment are also recommended.
