BACKGROUND/OBJECTIVES: Available data suggest that seasonal changes may influence the nutritional status and overall health of elderly individuals. Therefore, this study was conducted to investigate the effects of seasonal changes and related factors on energy and nutrient intake of older adults. SUBJECTS/METHODS: Individuals aged 65 years or over were prospectively enrolled in this single-center study (male: 11, female: 20). Data were collected between May 2013 and February 2014 during winter, spring, summer and autumn. Food consumption and biochemical parameters were taken during each season to assess the seasonal nutrition status of the elderly. Upon analysis of biochemical parameters (retinol, vitamin D and vitamin C), an high-performance liquid chromatography device was utilized whereas an Immulite 2000 device was utilized during analysis of serum folic acid and parathyroid hormone. RESULTS: Fruit, fat, egg and bread consumption varied seasonally in males and females (P < 0.05). During winter, daily energy intake was found to be greater than in other seasons in males (557 kcal) and females (330 kcal) (P < 0.05). Additionally, carbohydrates, vegetable protein, n-3 fatty acid and sodium intake increased in winter, while the n-6/n-3 ratio increased in summer among males (P < 0.05). Dietary fiber and sodium intake in winter, vitamin C, iron and zinc intake in spring, and cholesterol, retinol, vitamin D and niacin intake in autumn were found to be higher in females when compared to other seasons (P < 0.05). Serum parathyroid hormone level was higher in winter, and vitamin D level was higher in autumn in both genders (P < 0.05). In males, blood folic acid level was higher in winter, while vitamin C level was higher in females, and there was no seasonal variation in retinol concentration (P < 0.05). CONCLUSION: Food consumption and biochemical parameters showed significant seasonal variations in older adults. It is not clear if nutrition plans in older adults will benefit from consideration of seasonal changes in eating habits.

In myopathy patients, fat mass increases as the disease progresses, while lean body mass decreases. The present study aimed to investigate the overall nutritional status of Korean myopathy patients through surveys of diet and dietary habits, bioelectrical impedance analysis (BIA), and biochemistry tests, as well as the examination of related factors, for the purpose of using such findings as a basis for improving the nutritional status in myopathy patients. The energy intake of all participants was found to be insufficient at only 44.5% of Dietary Reference Intakes for Koreans 2010 (KDRIs 2010), whereas protein intake was sufficient at 89.8% of KDRIs 2010. Dietary fiber intake was found to be 58.4% of sufficient dietary fiber intake for adults according to KDRIs 2010. Calcium intake was found to be 55.0% and magnesium was 14.9% of the recommended calcium and magnesium intake for adults according to KDRIs 2010. With respect to quality of life (QOL), overall increase in QOL domain score showed significant positive correlations with vegetable fat intake (p < 0.05), vegetable protein intake (p< 0.05), and dietary fiber intake (p < 0.05). With respect to BIA, the mean phage angle of all participants was found to be 2.49 +/- 0.93degrees, which was below the cutoff value. As a study that examined nutrient analysis and dietary habits of myopathy patients in Korea, the present study is meaningful in providing the basic data for future studies that aim to present dietary guidelines for patients suffering from myopathy.

PURPOSE: As the rate of senior citizens living alone increases in the current aging society, there is much concern regarding the health and nutritional intake of solitary senior citizens. Therefore, this study compared the nutritional intake of senior citizens according to their family type. METHODS: In July and August of 2011, two senior citizen welfare centers in Seoul were visited to survey 267 elderly women. Excluding 54 subjects for which the data were incomplete, information from 213 subjects was analyzed. The subjects were divided into three family types, living alone (LA, n = 74), living with spouse (LS, n = 78), and living with children (LC, n = 61). RESULTS: The mean age of the LA group was the highest, while the mean age of the LS group was the lowest (p < 0.001) , and WHR of the LC group was the highest (p = 0.049). Income was the highest in the LS group (p < 0.001). Frequency of eating out was the lowest in the LA group (p = 0.031). By Duncan's multiple analysis, the amounts of energy intake, vegetable protein, fat, calcium, phosphorus, potassium, selenium, Vit D, Vit E, Vit B2, niacin, Vit B6, Vit B12, and cholesterol were significantly higher in the LS group compared with the LA or LC group (p < 0.05). The intakes of calcium, Vit D, Vit B12, and cholesterol were still significantly different among the three groups, even after adjustment for age and monthly income. The LA group ate less fruit and fish than the LS or LC group (p < 0.05). The LA group showed the lowest dietary diversity and the LS group showed the highest diversity (p = 0.014), however, the significance of dietary diversity score among the three groups disappeared after adjustment for age and monthly income. CONCLUSION: Elderly women living with spouse were receiving better nutrition than elderly women living alone or living with children. Therefore, solitary elderly women who do not live with their spouse or children should be offered greater opportunities to receive a balanced meal at a congregational kitchen or welfare center. To ensure their healthy diet, it is essential to provide continuous nutrition education with these groups in mind.

OBJECTIVES: The purpose of this study was to assess the association between dietary intake and osteoporosis risk in postmenopausal women. MATERIALS & METHODS: Bone mineral density was measured at the lumbar spine by dual-energy X-ray absorptiometry and a structured questionnaire was administered by a trained interviewer, which included information on sociodemo-graphics, medical and reproductive history, and dietary intake. The study sample included 134 osteoporotic and 137 non-osteoporotic women between 52 and 68 years of age. Nutrient variables were classified into tertiles. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated which compared the highest tertile with the lowest tertile as a reference group. RESULTS: ORs for osteoporosis were 1.47 (95% CI: 1.03~2.05) for total protein, 1.62 (95% CI: 0.51~3.92) for animal protein, and 2.98 (95% CI: 1.42~4.23) for sodium. ORs for osteoporosis in the highest tertile were: 0.42 (95% CI: 0.23~0.83) for vegetable protein, 0.72 (95% CI: 0.51~0.90) for Ca, and 0.65 (95% CI: 0.49~ 0.88) for Fe, relative to the respective lowest tertile. A brief food frequency questionnaire (FFQ) with 16 food items, was used in the cross-sectional survey. After adjustment for other risk factors for low bone mineral density, highest intake frequency of protein-sourced food was associated with lower risks for osteoporosis (OR: 0.57, 95% CI: 0.39~0.83, p for trend: 0.003). CONCLUSIONS: This results support that in order to prevent osteoporosis and low bone mineral density, adequate nutrient intakes are essential factors in postmenopausal women.

The purpose of this study was to provide basic data for nutritional education for juveniles' desirable vegetable intake by analyzing their vegetable intake, dietary habit and nutrient intakes according to gender of middle school students in Chungnam. The average age of the subjects was 15.0, height was 162.5 cm, weight was 53.5 kg and their average BMI was 20.1 kg/m2. The frequency of eating supper in girls was lower than that in boys. Many respondents answered that a meal-time was 10~20 minutes. Without gender difference, more than 90% respondents thought that vegetables were good for health. As for the preference of vegetable, subjects responded, "I am in the middle", "I like them", "I dislike them", "I like them very much", and "I dislike them very much" in order, without gender difference. The frequent eaten leaf vegetable was Chinese cabbage, the frequent eaten fruit vegetable was cucumber, and the frequent eaten root vegetable was radish. The favorite leaf vegetable was lettuce, the favorite fruit vegetable was corn, and the favorite root vegetable was sweet potato. The preference degrees of taro and ginger were very low. The reasons why they liked a vegetable were that it was delicious and they ate it at home often. In addition, the reason why they disliked vegetables was that they are untasty in flavor or texture and it showed that many students had a prejudice that vegetables were untasty. The intakes of plant protein, dietary fiber, ash and INQs of dietary fiber, calcium, vitamin C, folate, vitamin E in the group with high preference of vegetables were significantly higher than those of low preference group. The study results indicate that intake frequency and preference of root vegetables in juveniles are low and the major reasons of these results are taste and eating experience of vegetables. In addition, the intake amounts of dietary fiber and folate are poor in the subjects with low preference of vegetables. Therefore, families and schools should make efforts that juveniles can recognize the importance of vegetable intake and select various vegetables properly through the development of cooking methods and systematic nutrition education.

This study investigates the relationship of smoking on daily intake of nutrients and snacks in the Chungnam and Daejeon high school students. Up to date scientific nutrition education and counseling programs in the regular school system is needed for a professional nutrition education teacher. The primary objective of this study was to provide useful information to nutrition education teachers. A survey was conducted with 400 high school students in the Chungnam and Daejeon areas. 381 out of 400 questionnaires were analyzed with SPSS 12.0K. The subjects were composed of 49.8% male, 50.1% female and 40.9% regular high school students, 59.1% business high school students and smokers 43.1%, non-smokers 56.9%. 43.4% of smokers had been smoking since middle school. On analysis of daily nutrient intakes, 16 out of 19 nutrients except animal calcium, Vitamin A and Vitamin C were much more consumed by the smoking group than the non-smoking group non-significantly. Especially vegetable fat and Vitamin E were higher in the smoking group than the non-smoking group(p < 0.05). The intake ratio of carbohydrates: protein: fat was similar in the two groups (smoking group 55 : 15 : 29, nonsmoking group 56 : 15 : 28). Intakes of Vitamin B1 and potassium in comparison with the Korean dietary reference intakes (KDRI) were under 50% in both groups. However, sodium was taken over 200% compared to KDRI in both groups. Intakes of Vitamin C in the smoking group were as low as 76.5% in comparison to KDRI. Smokers need to increase the intakes of Vitamin C considering that smokers need to intake Vitamin C two times than non-smokers. Nutrient intakes from snacks in the smoking group were higher than the non-smoking group. Nutrients that originated from snacks which took over 20% among daily nutrient intakes were 12 nutrients (energy, fat, carbohydrate, calcium, P, Fe, K, Vitamin B1, Vitamin B2, Vitamin C, Vitamin E, dietary fiber) in the smoking group compared to 7 nutrients (energy, vegetable protein, fat, carbohydrate, calcium, Vitamin B2, Vitamin C) in the non-smoking group. The smoking group was significantly paying more money for snacks each month than the non-smoking group was (p < 0.01). Periods of consumption were irregular in the smoking group(p < 0.05) and the smoking group was used to taking snacks in the morning compared to the non-smoking group. The smoking group preferred sweets and high calorie food over other snacks in comparison of the non-smoking group. The nonsmoking group had better eating habits than the smoking group

Pleurotus sajor-caju (Fr.) Singer was cultivated on selected agro wastes viz. cotton stalks, groundnut haulms, soybean straw, pigeon pea stalks and leaves and wheat straw, alone or in combinations. Cotton stalks, pigeon pea stalks and wheat straw alone or in combination were found to be more suitable than groundnut haulms and soybean straw for the cultivation. Organic supplements such as groundnut oilseed cake, gram powder and rice bran not only affected growth parameters but also increased yields. Thus bioconversion of lignocellulosic biomass by P. sajor-caju offers a promising way to convert low quality biomass into an improved human food.

An alpha-amylase inhibitor (alpha-AI) was isolated from white kidney beans (Phaseolus vulgaris L) by ethanol fractional precipitation, ion exchange chromatography and gel filtration column chromatography. It was a homogeneity glycoprotein demonstrated by SDS-PAGE and gel filtration on CL-6B. The glycoprotein contained 88.2% protein and was rich in aspartic acid, glutamic acid, leucine, threonine and serine. The carbohydrate moiety was consisted of Man, Glc, Gal and Xyl in a mole ratio of 2.42: 1.50: 1.52: 1.00. The glycan and the core protein backbone was connected by O-linkage as determined by beta-elimination reaction. The continuous oral administration of the alpha-AI (150 mg x kg(-1) x d(-1)) for 7 days can lower fasting blood glucose and 300 mg x kg(-1) x d(-1) alpha-AI for 7 days can improve the sugar tolerance on alloxan-dependent diabetic model rats. The result showed the alpha-AI obtained from white kidney beans had good hypoglycemic effect on alloxan induced diabetic rats and may have high potential pharmaceutical value as a regulative digestive-starch degradation in patients suffering from diabetes.

This study was conducted to examine dietary factors affecting bone status in the rural aged men. Quantitative ultrasound measurements (QUS) of bone, that may reflect certain architectural aspects of bone, have been shown to be associated with bone mineral density and fracture. Information of diet and anthropometry was collected in 164 aged men. Dietary intake data were obtained by 24-hour recall method. Measurements of the speed of sound (SOS, m/s), at distal radius, mid-tibia, phalanx, were performed using Omnisense 7000S analyzer (Sunlight Ltd., Tel Aviv, Israel). T-scores for bone SOS measurements at distal radius, mid-tibia and phalanx were 0.60, 0.03 and -0.42 respectively. The prevalence of osteopenia by use of the WHO criteria was 17.7% at the mid-tibia and 25.3% of the subjects at the distal radius. Age were negative association with bone SOS at three sites. Osteopenia group of radius were significantly lower in total foods and vegetable intakes than normal group. After adjusted for age, vegetable intakes were significantly and positively related to bone SOS at the radius. The bone SOS of the tibia were significantly and positively related to vegetable protein, iron, folate and vegetable intakes, but negatively related to fat intakes. Multiple regression analysis showed that bone SOS of tibia was positively associated with folate intakes. Vegetable intakes were positively associated with the bone SOS at three sites. These results indicate that the consumption of vegetables, sources of folate, may have a effect on bone status of men.

The purpose of this study was to evaluate nutritional value of traditional fermented foods by dietary intake of university students living in Chungnam. 210 students were asked for their daily food intake using 24-hour recall method for 3 days. And daily nutrient intakes from total foods and fermented foods were analyzed and compared. The mean weight, height, and BMI of the subjects were 67.36kg, 174.39cm, 22.15kg/m2 in men and 53.45kg, 161.86cm, 20.40kg/m2 in women, respectively. The daily intakes of protein, phosphorus, and vitamin B1 were 106.82%, 137.88%, and 108.99% of the Korean RDA. However, the energy, calcium, iron, vitamin A, vitamin B2, niacin, vitamin C intakes did not reached the RDA for Koreans. The fermented food intake was 9.09% of total food intake. And the percentages of fermented food intakes were 81.53% for Kimchi and 14.75% for Chang. The vegetable protein, vegetable oil, dietary fiber, calcium, phosphorus, iron, sodium, potassium, vitamin A, vitamin B1, vitamin B2, niacin and vitamin C intakes per 1000kcal consumption from fermented foods were significantly higher than those from total foods. The fermented food intake showed positive correlation with iron, and plant iron intakes. In conclusion, the percentage of fermented food intake was about 9% and the major items were Kimchi and alcoholi beverages in university students. Fermented food intake may be important to improve the intakes of calcium, iron and vitamin.
