This study was conducted to evaluate the rate of obesity of 212 women (age 45-60 years) in Seoul and the Kyunggi area through analysis of BMI and the dietary life factors related to obesity using a survey on dietary habits, dietary assessment, and nutrient intake. The height of the underweight group was taller than normal. The height of the obese group was equal to that of the normal group, but the weight was 8.5 kg greater than the normal group. Women in the underweight group consumed meals irregularly, and only 33.4% ate breakfast. Additionally, the rate of overeating was low in the underweight group, and milk, dairy products (yogurt, etc.), fruit, and fruit juice were consumed more than once a day. It was found that 62.1% of the women in the obese group never ate out, and the rate of eating one serving of fruit, drinking one cup of fruit juice, and eating various kinds of foods was high. The average point of women's dietary life was $21.9{\pm}2.9$, and 12.7% of all women responded that their dietary life was good. However, in the obese group, only 6.9% of the women reported that their dietary life was good. Evaluation of snacking habits revealed that the underweight group consumed a high level of carbonated drinks and ice cream, whereas for in the obese group, 24.1% of the women consumed milk and its products and 5.6% regularly consumed fast and fried foods. Evaluation of nutrient intake revealed that the consumption of energy, protein, vitamin A, vitamin $B_1$, $B_2$, $B_6$, niacin, vitamin C, and vitamin E was high in all of the groups, but the intake of folic acid in the underweight group was lower than the required level. Overall, 24.1% of the women in the obese group were found to have metabolic diseases, mostly hypertension (43%). In conclusion, a balanced diet to avoid excessive nutrient intake is needed to prevent obesity.
Sarcopenia is a leading cause of increased medical and nursing care costs among the elderly. In Korea, preventive measures for sarcopenia are mostly targeted toward the general elderly population without specific diseases. However, it is also necessary to implement measures for elderly individuals living in nursing homes and hospitals, where the prevalence of sarcopenia is high. Currently, computed tomography and/or magnetic resonance imaging are considered standard diagnostic tools. However, their complexity and time-consuming nature make them unsuitable for clinical use. The exact pathophysiological mechanisms of sarcopenia are unclear, as they involve various molecular biological pathways, including decreased exercise, protein and nutrient intake, changes in testosterone and growth hormone, and inflammation. Sarcopenia symptoms can lead to several diseases, such as osteoporosis, fractures, dementia, diabetes, and cardiovascular disease. Vitamin B deficiency is a significant factor in sarcopenia induction, with B vitamins being directly involved in energy and protein metabolism and nerve function. Vitamin B deficiency can lead to neuromuscular and neurogenic disorders, which often overlap with sarcopenia. Suboptimal intake of B vitamins, malabsorption, and anorexia are common among the elderly. This study aims to provide information on the role of water-soluble B vitamins in preventing and controlling muscle mass loss and deterioration among the elderly with sarcopenia. In addition, we discuss the potential of myokines from the B vitamin family in modulating sarcopenia.
The effects of the amount of red pepper intake per a day on the capsaicin threshold, nutrient intake, and anthropo-metric measurements were investigated in 100 female students of university. Three 24-hour recalls were performed to estimate usual nutrient and red pepper intake of free-living participants. The solutions containing capsaicin at concentration of 0.05, 0.1, 0.2, 0.3, 0.4, 0.5ppm used for the evaluation of hot-taste detection threshold. Subjects were asked to recognize the burning sensation after tasting l0ml of each test solution in ascending order of capsaicin concentrations. Mean intake of red pepper was 4.6 g/d and the capsaicin threshold was 0.27 ppm. The detection threshold for capsaicin was correlated with the amount of pepper intake per a day. Red pepper intake was correlated with energy, protein, lipid, carbohydrate, Iron, vitamin A, vitamin B$_2$ niacin, and vitamin E intakes. However, it was not correlated with intake of calcium, vitamin B$_1$ or vitamin C. The red pepper intake was negatively correlated with fat mass and waist girth and the capsaicin threshold was also negatively correlated with pulse. In conclusion, red pepper intake was associated with nutrient intake and capsaicin threshold whereas it was negatively correlated with fat mass and waist girth.

This study was carried out to assess the food habit index of the long-lived elderly who were aged over 85 years living in Ganghwa-gun. A survey was conducted during December 2003. Dietary nutrient intake data was obtained through the 24-hr recall method. The subjects were 96 (32 males, 64 females) aged people and divided into three groups based on food habit index scores. Such as group A: good $16\∼20$, group B: fair $11\∼15$, and group C: poor $5\∼10$. The three groups of the subjects were 90.7 years of age and $21.3\;kg/m^{2}$ of BMI on average. Healthy eating index scores of the subjects were $9.4\%$ in group A, $54.2\%$ in group B and $36.5\%$ in group C. Their level of education were lower and their levels of living standards tended to have been middle and lower of the middle class. The percentage of living together with their families or spouses in all groups were over $60.0\%$ and the rates of the subjects who have responsibility for their meal preparations were also very high in all groups. Most subjects tended not to drink nor smoke, and spend $8\~10$ hours for their sleep. The percent of number of diseases in group A was lower than in groups B and C. Their dietary habits such as taking three meals a day regularly have shown that they have good eating habit in general. There was a positive correlation between the eating behaviors and nutrient intakes. The protein, animal protein, fat, PUFA, vitamin E, vitamin $B_{2}$, niacin, P and K intaks in group A were significantly higher than that of the groups B and C. For group A of good food habits aged had no sufficient intake of Ca and vitamin A than the Korean RDA and long-lived elderly of group C in Ganghwa areas had worse nutrients intakes, especially Ca, vitamin A, vitamin $B_{2}$ and vitamin E. According to this research having a good eating habits could be considered as increasing of the health and nutritional status. (Korean J Community Nutrition 10(6) $892\∼904$, 2005)
This study was carried out to investigate the dietary behaviors and nutrient intake of high school girls in Iksan and Seoul cities. The subjects consisted of 122 students in Iksan city, and 136 students in Seoul city. The proportion of subjects who eat meals irregularly was higher in Iksan ($94.8\%$) than in Seoul ($80.9\%$). The proportion of subjects who skip meals was also higher in Iksan ($61.5\%$) than in Seoul ($56.6\%$), and most of them ($69.7\%$) skipped breakfast, even thought they thought that it was the most important meal ($86.4\%$). The subjects tended to overeat at lunch ($41.9\%$) and dinner ($55.4\%$). The main reasons that the subjects skipped a meal were a lack of time (50.7%) and poor appetites ($23.7\%$). Most of the subjects ($57.4\%$) had tried to control their body weight by taking drugs ($40.5\%$), doing exercise ($34.5\%$), and controlling their diet ($25\%$). The average intake of nutrients and energy was significantly higher (P<0.05, p<0.01) in Iksan than in Seoul. The intake was below the RDA recommendations except for phosphorus in I ksan, but was above it except for calcium, iron, and vitamin B2, in Seoul. The indexes of nutritional quality (INQ) of calcium (0.5), iron (0.6), vitamin A (0.8), vitamin B2 (0.7), niacin (0.9), and vitamin C (0.9) were under 1.0 but those of protein (1.0), phosphorus (1.2) and thiamin (1.0) were over 1.0. The INQ of the other nutrients, except protein and vitamin C, was significantly higher in Seoul than in Iksan.

Pinus pollen is used as the chief ingredient for Song-wha-dashik (Korea's traditional pattern-pressed candy). It has been the food stuff indispensable especially on the occasion of performing ancestral rites and holding a banquet since Shilla and Koryo Dynasty. In this paper, therefore, a new examination is made of the nutritive ingredients of the very Pinus pollen. Analysis has been made of the proximate composition, minerals, heavy metals, vitamins and free sugars of the Pollen of both Pinus densinora Siebol et Zuccarini and Pinus rigida Miller. In the proximate composition, Pinus rigida Miller is high except in free sugar ; crude ash (4.0%), crude protein (15.0%), crude fat (2.5%), crude fiber (17.5%). A lot of minerals have been found in both the samples. They contain Mg, Cl, Ca, Fe, Mn, Na, Zn, etc. In heavy metals, both the samples contain the same quantity of Cd(0.3 ppm) and the contents of Pb, Cu, and As are lower than the maximal limit permitted for food stuff. The contents of vitamin B$_1$, B$_2$, vitamin C are a little higher in Pinus rigida Miller : in vitamin E, on the contrary, Pinus densiflora Siebol et Zucarini (1.6 mg) doubles Pinus rigida Miller (0.8 mg). In free sugars, the results is as follows : 6.6%/6.9% in sucrose : 0.2% in fructose : 2.1% /2.9% in glucose respectively.
The cyutotoxic effects of hot water soluble polysaccharides extract(PS) from the mushroom, Lentinus edodes, and in combinations with vitamin A or vitamin E on life span of ICR mice bearing P388 cancer cells and in vitro against P388 cancer cells were examined. The chemical components of PS and fractions were analyzed and survival time and cell number of P388 treated with extract fractions with and without vatamin A or E supplementation were also measured. The results obtained were summarized as follows; The extract of fraction B was shown to have the highest antitumor activity against P388 implanted in ICR mice. The antitumor fraction B was consisted of 82.0% of polysaccharide and 4.2% of protein. All three fractions seemed to have in vivo antitumor activity against P388, and fraction B showed the highest activity, In vitro P388 cell growht was inhibited 76%, 89%, 54% by the addition of fraction A, B and C respectively. Vitamin A or E did not appear to have any accelerating effects on either in vivo or in vitro cell cytotoxicity when each of them was combined with the PS and fractions. All three fractions contained more than 68% of polysaccharides. The fraction B showed the highest value of 88% in polysaccharides. Monsaccharides of the fraction B were identified as galactose(59.1%), glucose(29.2%), fructose(2.8%) and uronic acid(4.2%). Hydrolysis of protein from the fraction B was didentifed to have 17 kinds of defined and 5 undifined amino acids. The inhibitory effects of the hot water extracts from mushroom against cancer cell growth of P388 were stronger than the control group. And the survival time of ICR mice was shown to be 161% between the control group and the experimental groups.
Comparative studies regarding the nutritional status of 93 home-living elderly people taking free congregate lunch meals(FL) and 87 middle income class elderly people(MI) were performed in Taejon city. Data was obtained from questionaires, anthropometry and interviews for the 24-hour dietary recall of 2 nonconsecutive days during August, 1996. The average age for FL was 75.8 years. The monthly familly income for FL belonged to the low-income class. FL females had lower heights and weights than MI females. The average daily nutritional intake of both FL and MI were low, particularly in FL whose %RDA of energy was 68.5%, protein 65%, Ca 29.6%, Fe 50.8%, vitamin A 34.5%, vitamin E 30.5%, riboflavin 40.6%, vitamin C 76.9%. MI's %RDA of energy was 76.4%, protein 80.a2%, Ca 48.1%, Fe 78.6%, vitamin A 67.3%, vitamin E 117.4%, riboflavin 45.6%, vitamin C 136.5%. Comsumption of Zn, vitamin $B_6$ and folic daily average. There was no nutrient having average INQ(Index of nutritional quality) over 1 for either group. The INQs for protein, Ca, Fe and vitamin A were 0.802, 0.377, 0.625 and 0.296 in FL, and 0.900, 0.601, 0.784 and 0.602 in MI, respectively. The MAR(Mean adequacy ratio) was low with the value of 0.500-0.518 in FL and 0.630-0.723 in MI. The percentage of main nutrients from lunch was the highest among the three meals for FL males, while that from breakfast was the highest for MI. Free lunches taken by FL supported higher percentages of main nutrients than home-lunches taken by MI. Eating-out was done more frequently by MI than by FL and that eating-out brought them more nutritional intake. The above data indicated that the dietary nutritional intake status of the FL elderly was very poor in both quantity and quality and that free congregate lunch significantly contributed to the daily nutrient-intake for the FL elderly.

In order to create the national food nutrient database, a total of 41 animal foods (ham, seafood, edible insects and eggs) were analyzed for their vitamin B12 content and the applied immunoaffinity-HPLC was verified. Ham vitamin B12 contents were 0.30-0.65 ㎍/100 g. Seafood showed relatively high vitamin B12 level, where the values of fermented clam were the highest (26.80 ㎍/100 g) followed by fermented pollack roe. Vitamin B12 was not detected in silkworm pupae and beetles, while relatively high levels were found in the two-spotted cricket imago (6.70 ㎍/100 g). Chicken and quail egg yolk had roughly 100- and 30-times higher vitamin B12 levels as compared to their egg white. Vitamin B12 contents in quail and chicken eggs were significantly enhanced by boiling (p<0.05). Results based on accuracy (97-102% recovery) and precision (<5% RSD) indicate that this study provides reliable vitamin B12 information on animal foods consumed in Korea.
The study was conducted to investigate the role of vitamin E in the high altitude hypoxia-induced damage to the intestinal barrier in rats. Sprague-Dawley rats were divided into control (Control), high altitude hypoxia (HH), and high altitude hypoxia + vitamin E (250 mg/kg $BW^*d$) (HV) groups. After the third day, the HH and HV groups were placed in a hypobaric chamber at a stimulated elevation of 7000 m for 5 days. The rats in the HV group were given vitamin E by gavage daily for 8 days. The other rats were given equal volume saline. The results showed that high altitude hypoxia caused the enlargement of heart, liver, lung and kidney, and intestinal villi damage. Supplementation with vitamin E significantly alleviated hypoxia-caused damage to the main organs including intestine, increased the serum superoxide dismutase (SOD) (p< 0.05), diamino oxidase (DAO) (p< 0.01) levels, and decreased the serum levels of interleukin-2 (IL-2) (p< 0.01), interleukin-4 (IL-4) (p<0.001), interferon-gamma ($IFN-{\gamma}$) (p<0.01) and malondialdehyde (MDA) (p<0.001), and decreased the serum erythropoietin (EPO) activity (p<0.05). Administration of vitamin E significantly increased the S-IgA (p<0.001) in ileum and significantly improved the expression levels of occludin and $I{\kappa}B{\alpha}$, and decreased the expression levels of hypoxia-inducible factor 1 alpha and 2 alpha ($HIF-1{\alpha}$ and $HIF-2{\alpha}$), Toll-like receptors (TLR4), P-$I{\kappa}B{\alpha}$ and nuclear factor-${\kappa}B$ p65(NF-${\kappa}B$ P65) in ileum compared to the HH group. This study suggested that vitamin E protectis from intestinal injury caused by high altitude hypoxia environment. These effects may be related to the HIF and TLR4/NF-${\kappa}B$ signaling pathway.
