Ten healthy wome 2-~25 years participated in a 5-week metabolic study to investigate the daily riboflavin requirement of Korean women. Three daily menu and meal patterns were used. Low riboflavin(LR) diet provided riboflavin at a level of 0.71mg / 1000Kcal based on food composition table. High riboflavin(HR) diet provided 1.14mg / 1000Kcal. The riboflavin status was assessed by erythrocyte glutathione reductase activity coefficient(EGRAC) and urinary exretion of riboflavin. Mean EGRAC of LR period and HR period were 1.17+0.08 and 1.01+0.03, repectively. There were discrepanices of riboflavin content of experimental diet between chemical analysis and calculation by Korean food composition table. Urinary riboflavin excretion of subjects was acceptable over the whole study period. It appeared that 0.71mg / 1000Kcal is requirement of riboflavin to maintain EGRAC withing normal range. Thus, it is suggested that current recommendation of 0.6mg / 1000Kcal of riboflavin intake may not be adequate as RDA level in Korea.

The prevalence of obesity has been increasing worldwide. Several dietary treatments have been suggested to control weight, and recent guidelines recommend individualizing the composition of macronutrients. Carbohydrates are the most important nutrients in meals, and carbohydrate restriction is a dietary strategy that promotes weight loss. A low-carbohydrate diet is effective for short-term weight loss and can help improve glycated hemoglobin, systolic blood pressure, diastolic blood pressure, and triglyceride levels; however, the long-term effects and safety of this diet remains doubtful. In the short term, there is a risk of gastrointestinal symptoms such as vomiting, diarrhea, constipation, and gastroesophageal reflux, and type 1 diabetes patients are at risk of severe hypoglycemia, while in the long term, it can lead to malnutrition and decreased exercise capacity. Thus, rather than limiting the intake of carbohydrates, it is important to limit the intake of refined grains, sugar, honey, syrup, and sweetened beverages while maintaining the planned carbohydrate intake rate and improving meal quality.

Dietary counseling is undoubtedly important for prevention and treatment of chronic diseases. Several dietary counseling methods have been developed and used in Japan to promote healthier diets. However, in Japan, few studies have established effective counseling methods. We developed a computer-assisted tailored dietary counseling system with self-administered diet history questionnaire (DHQ) to assess nutrient intakes and the feedbacks for counseling. We examined the effectiveness of the system in three studies , two among mildly-hypercholesterolemic and one among healthy subjects. We observed significant changes in intakes of targeted nutrients in all three studies. We also observed favorable changes in the corresponding serum and urinary biomarkers in two studies, i.e., non-significant change in serum cholesterol, serum carotene and vitamin C, and a significant change in 24-hour urinary excretion of sodium. In addition, one of the studies observed a significant modified dietary habit for one-year after the intervention was completed. No unfavorable change was observed for non-targeted nutrients in all three studies. The dietary counseling system with DHQ was concluded to be effective among motivated high-risk and healthy subjects. The system's application to other diseases and populations such as children, adolescents, and elderly, should be examined further. (J Community Nutrition 5(2) : 112-119, 2003)

The association between nutrient intake and nutritional status was investigated with anthropometric measurements, body composition and blood biochemical indices in 56 healthy young men fed balanced diet for two years. Compared with Korean recommended dietary allowances (Korean RDA), all nutrient intakes were adequate. Height and body weight were significantly (p < .01 - p < .05) positively correlated to the intakes of energy, protein, sodium, potassium vitamin A and vitamin $B_1$. The lean weight was significantly (p < .001 - p < .05) correlated to the intake of energy, protein, sodium, potassium, vitamin A, vitamin B$_1$. niacin and vitamin C. The skinfold thickness of triceps and suprailiac was significantly (p < .01 - p < .05) correlated to the intake of energy, sodium, potassium, but that of thigh was not correlated. The significant correlations neither between nutrient intake and blood biochemical indices nor between nutrient intake and blood pressure were shown. These results suggest that nutritional status as anthropometric indices and body composition is associated with nutrient intake in young healthy adults on balanced diet, however, the nutritional status as blood biochemical indices of active people is neither endangered nor improved in comparison with less active ones.

Background and Aim : As one of the World Cultural Heritage, Joseonwangjosillok is a history book including general state affair, social affair, economy, astronomical and atmospheric phenomena, art, music, eat. as well as the very private life of the king. With Joseonwangjosillok, we will look into health and death of the king and apply it to the regimen and recommended life-style of the aged. Materials and Method : With the archive of Joseonwangjosillok and medical text books such as Donguibogam Huang Di Nei Jing as reference, we tried to inquire the work and life of the kings of the Joseon dynasty, find connection with the regimen recommended life-style, and suggest medical guidelines for the aged as geriatric society is coming. Result : The Kings of the Joseon dynasty had omnipotent power, so that they lived quite much better lift than common people. But their average lifetime is estimated to be no better than that of ethers. Probably overwork, mental stress, rich fatty diet and lack of exercise took healthy life from them. Conclusion : Even if they had unlimited power, the state-of-the-art medical treatment hardly helped the Kings live better and longer life than common people. To keep and promote healthy lift for the aged, they need moderate exercise, appropriate rest, balanced diet, seen dissolving with reasonable environment.

The share of the population that is aging is growing rapidly. In an aging society, technologies and interventions that delay the aging process are of great interest. Dietary restriction (DR) is the most reproducible and effective nutritional intervention tested to date for delaying the aging process and prolonging the health span in animal models. Preventive effects of DR on age-related diseases have also been reported in human. In addition, highly conserved signaling pathways from small animal models to human mediate the effects of DR. Recent evidence has shown that the immune system is closely related to the effects of DR, and functions as a major mechanism of DR in healthy aging. This review discusses the effects of DR in delaying aging and preventing age-related diseases in animal, including human, and introduces the molecular mechanisms that mediate these effects. In addition, it reports scientific findings on the relationship between the immune system and DR-induced longevity. The review highlights the role of immunity as a potential mediator of the effects of DR on longevity, and provides insights into healthy aging in human.

An experiment was performed to determine if buckwheat intake would improve insulin sensitivity in in normal healthy ras and steptozoticin-induced diabetic Sprague-Dauley rats. For four weeks, rats were fed either corn starch as a cotnrol diet or buckwheat as an experimental diet. As a result, the insulin sensitivity and plasma glucose levels in normal rats were not significantly affected by buckwheat fedding. The insulin sensitivity was lower in diabetic rats than in normal rats(p<0.05). Buckwheat tends to decrease the final plasma glucose level and increase insulin sensitivity in diabetic rats, but there was no sifnificant difference. Another five-week experiment was conducted to determine protein digestibility and protein utility in normal healty rats ad streptozotocin-induced diabetic rats on a control diet or buckwheat diet. The diet composition in this experiment was the same as the preceeding experiment. In the cotnrol diet groups, the protein digestibility in diabetic rats was significantly lower than that in normal rats(p<0.05). Buckwheat reduced protein digestibility in both normal and disbetic rats(p<0.05). Interestingly, in buckwheat diet groups, protei digestibility in diabetic rats was similar to that in normal rats. Protein utility was significantly lower indiabetic rats than in normal rats. This phenomenon was observed as early as the first week of the feeding period. However, protein utility was not sifnificanlty altered in both normal and diabetic rats by buckwheat feeding. It follows that decreased protein digestibility and utility in diabetic rts are not further aggravated by buckwheat feeding, suggesting that buckwheat can be a feasible supplement food for the diabetic therapeutic diet.

Objectives: This study was conducted to compare dietary habits, weight control behaviors, eating disorder risk and depression among middle school girls who were at various stages of dieting. Methods: Subjects were 391 girls attending a middle school in Kyeonggido, Korea. All the information was gathered by self-administered questionnaires. Eating disorder risk and depression were assessed using EAT-26 and PHQ-9, respectively. Data were compared among 4 groups; no interest in a diet (N=112), had experienced dieting (N=86), on diet currently (N=71), and plan to diet (N=122). Results: A higher number of students currently on diet tended to be unsatisfied with their own weight (p < 0.01), overestimated their weight (p < 0.05), and weighed own body frequently (p < 0.001), compared to those with only experienced dieting in the past or those who plan to diet, despite similar weights and body mass index. The students who experienced dieting in the past or those who plan to diet appeared to have several undesirable as well as desirable dietary habits and their risk of eating disorder was significantly more prevalent compared to those without an interest in dieting (p < 0.01), although significantly less prevalent compared to those currently on a diet. Conclusions: We conclude that unnecessary dieting is common among middle school girls and providing proper education with regard to healthy weights is needed to enhance their physical as well as psychological wellbeing.
