Populations both in the US and worldwide are aging. It is projected that by the year 2030 the population of Americans over 65 will increase to 70 million, more than twice their number in 1998. About one-third of elderly over the age of 65 have debilitating chronic health conditions that greatly impede their activities. Age-associated chronic diseases are believed to be associated with free radicals and the imbalance in antioxidant and oxidative stress contributes to development of several chronic health conditions. Diet and nutrients can have great impact in the health status of elderly. Several factors may contributor to the inadequate consumption of nutrients in elderly, including an inability to chew food adequately, polypharmacy, living along and limited income. Low intake of energy and several micronutrients are common among the elderly. Although overt deficiency of nutrients among the elderly is not common. a recent study showed that while elderly consume more fat, the total energy intake is low among the elderly. Inadequate intake of antioxidant nutrients such as vitamin E in elderly may contribute to the development of chronic health problems. Intake of higher than normal RDA levels of vitamin E for long periods of time has been shown to reduce the risk of many degenerative diseases, such as cardiovascular diseases(CVD) and cancer, and improve immune response in elderly. High intake of other antioxidants is also associated with reduced risk chronic diseases. Dietary antioxidants are abundant in fruits and vegetables. However, due to variety of factors, the elderly may not be able to receive these and other micronutrients through diet. Therefore, supplemental intake of micronutrients in the form of multi vitamins/minerals and/or specific micronutrients is a more practical approach to the maintenance of health status in the elderly.

The purpose of this study was to investigate eating behavior, nutritional status and health conditions of college students attempting a weight control. The subjects are 88 students of the Daegu area. Their weight, height, triceps, and mid-arm circumference were measured and their dietary intake and eating behavior were obtained by using questionnaires. The 24-hour recall was obtained from the subjects. The results are summarized as follows: The average height, weight and BMI of the attempt and no-attempt male and female students were 171.2cm, 70.7kg and 24.1; 170.4cm, 79.9kg and 27.5; 159.3cm, 60.9kg and 24.0; 157.7cm 60.1kg and 24.2, respectively. Energy intake of the attempt and no-attempt male and female group was 63.9%, 61.8%, 76.2% and 83.9% of RDA respectively. Protein intake of each group was 97.5%, 83.9%, 60.1% and 67.3% of RDA respectively. The following items registered a negative correlation weight and carbohydrate, weight and Na intake, weight and vitamin C intake, PIBW and Na intake, TSF and fiber intake, TSF and Na intake, TSF and vitamin C intake, MAMC and Na intake, and MAMC and vitamin C intake. A relative magnitude of factors affecting weight control was analyzed by Stepwise multiple regression analysis. Overall results about relative influence of independent variables to the dependent variable(weight control) indicated that the BMI (p<0.01) was the most significantly correlated with weight control in all subjects. The results of this study suggest that the extensive nutrition education in the weight control program should be emphasized to prevent obesity early.

The purpose of this nutritional survey on the actual conditions of group feeding is to be of value for promoting the health of the blue collar workers through consice understanding of food intake trends in businesses as well as realizing our desirable target. The results of the survey are summarized as follow. 1, Status of food economics 1) The average feeding cost amounts to 453 won per day per person. 2) The average school years of food buyers were 12.3 years, cookers were 12.0 years and dieticians were 14.5 years. 3) Kerosene(57.6%), gas(24.2%), electric(12. 1%) and cool briguette(6.1%) were used for fuel. 2. Status of food intake The average food intake per person per day in surveyed businesses was 1193.4g. The total intake of food was consisted of 42% grains, 40.4% vegetables, 4.7% legumes, 4.5% fish and shellfish, 4.0% potatoes, 1.6% meats, 1.0% seasonings. 0.8% eggs, 0.5% sea weeds, 0.3% oil and fats, 0.1% sugar. These findings led us to the conclusion that workers in the surveyed businesses retied heavily on plant foods. 3. Status of nutrient intakes 1) The average intake of calorie was 2752.6 kcal per day, which was slightly higher than 2,700 kcal of RDA. Though the quantity was above the level of RDA, it was largely from plant foods. 2) The average intake of protein was 84.7g per day, which was slightly higher than 80g of RDA. 3) The average intake of fat was 26g per day, which was much lower than 36g of RDA. 4) The averse intake of calcium was 532.3mg per day, which was lower than 600mg of RDA. 5) The average iron intake was 9.8mg per day, which was much lower than 10mg of RDA and 18mg of HDA for women. 6) Intakes of vitamin group were high. Especially, intake of vitamin A was 2-3 times higher than RDA and intake of vitamin C and niacin were 2 times higher than RDA.

The labor environment in Korea has changed and problems related to employment types are treated as important issues. Especially, the ratio of irregular workers has not only increased relatively, but the labor conditions in Korea also have worsened in the current years. Studies have reported an association between temporary workers and the prevalence of diseases. However, there is insufficient research on chronic disease and employment types. Methods: The current study examines the prevalence rate of diseases and health behavior by categorizing employment types among Korean adults. Data were obtained from the 2016-2018 Korea National Health and Nutrition Examination Survey. Totally, the data of 2,366 workers (1,239 regular and 1,127 irregular) were analyzed in the study. The types of employment were classified by a questionnaire querying about working conditions. The results showed that irregular workers earned less than regular workers and had a significantly higher prevalence of diabetes mellitus and hypertension. We propose that if discrimination related to working conditions were relieved, irregular workers would be able to invest more time to exercise and doing check-ups regularly. In addition, individual nutrition consultations considering the knowledge and personal environmental factors of each individual are necessary for the improved health of all workers.

The purpose of this study was to investigate the dietary habits and nutrient intakes of the elderly living in Songnam area. Responses from 318(153 men, 165 women) elderly individuals aged from 58 to 92 were analyzed. The results of this study are as follows. Regular dietary habit scores of the elderly women were worse than those of the men. Balanced dietary habit scores turned out to be the lowest among the various measured indices. The dietary assessment data showed that the energy intakes of males and females were 86.8% and 83.1% of the RDAs, respectively. The nutrients taken less than RDA on the daily basis were protein, calcium, iron, vitamin A and vitamin B$_2$. Nutrient intakes were gradually decreased as the age increased. Energy intakes of males and females from carbohydrate were 70% and 73% respectively. Vitamin A, vitamin B$_2$, and calcium were the most deficient nutrients on the basis of the intake percentage of RDA. Therefore, to improve nutritional status of the elderly, it is recommended that intakes of vitamin A, B$_2$ and calcium-rich food should be increased. Also suitable dietary guidelines and educational programs seem to be necessary for promoting health conditions of elderly people in Songnam area.

Objective: This study was carried out to determine the effects of elevated dietary cation and anion difference (DCAD) on dry matter intake (DMI) and ruminal fermentation pattern in lactating dairy goats under tropical conditions. Methods: Ten dairy goats were divided into two groups of five animals each. The groups received diets at different DCAD levels, either a control diet (22.81 mEq/100 g dry matter [DM], DCAD-23) or a DCAD-39 diet (39.08 mEq/100 g DM, DCAD-39). After parturition, DMI and water intake were recorded daily. Ruminal fluid and urine were collected, and nutrient digestibility measurements were carried out at 8th weeks postpartum (PP-8). Blood samples were collected at PP-4 and PP-8 to measure plasma leptin. Results: Dry matter intake/body weight (DMI/BW) at PP-8 of the animals fed the DCAD-39 diet was significantly higher than those fed with DCAD-23 diet (p<0.05). Animals fed with DCAD-39 consumed more water than those fed DCAD-23 over 24 h, particularly at night (p<0.05). Ruminal pH, acetate concentration, and urinary allantoin excretion increased with the DCAD-39 diet, whereas ruminal butyrate concentration was lower with the DCAD-39 diet. On the other hand, other ruminal parameters, such as total volatile fatty acid concentration, propionate molar proportion and acetate/propionate average ratio, were not affected by increased DCAD supplementation. Apparent digestibility was improved by increased DCAD supplementation. Plasma leptin concentration was higher with DCAD supplementation. Conclusion: When feeding goats with DCAD-39 under tropical conditions, an increase in DMI was associated with improved apparent digestibility of nutrients, ruminal fermentation and microbial protein synthesis. An increase in plasma leptin concentration could not explain the effect of high DCAD on DMI.

Objective: Our recent series of laboratory- and large-scale experiments confirmed that under aerobic and anaerobic conditions, sodium metabisulfite (SMB) was effective in preserving nutrients and antioxidant capacity of highly perishable fruit and vegetable discards (FVD). Hence, the purpose of this study was to examine how partial inclusion of SMB-treated FVD in total mixed ration (TMR) influences in vitro ruminal fermentation, whole-tract digestibility, nitrogen metabolism, blood metabolites, and voluntary feed intake of sheep. Methods: The FVD were mixed thoroughly with 6 g SMB/kg wet biomass and kept outdoors under aerobic conditions for 7 days. Four TMRs including four levels of SMB-treated FVD (as-fed basis) at 0%, 10%, 20%, and 30% (equaling to 0%, 1.9%, 3.8%, and 5.7% on dry matter basis, respectively), were prepared as replacement for corn grain. The ruminal fermentation metabolites were studied using an in vitro gas production test. Four mature male Corriedale sheep were assigned at random to the 4 diets for two separate sub-experiments; i) digestibility trial with four 21-d periods, and ii) voluntary feed intake trial with four 28-d periods. Results: Inclusion of SMB-treated FVD in the TMR tended to quadratically increase partitioning factor. No effect was seen on total-tract digestibility of organic matter, ether extract, crude protein, and acid detergent fiber, except for neutral detergent fiber digestibility that tended to linearly increase with increasing SMB-treated FVD in the TMR. The progressive increase of FVD preserved with SMB in the diet had no effect on nitrogen metabolism. Treatment had no effect on serum antioxidant capacity and blood metabolites assayed. Voluntary feed intake was not impaired by inclusion of SMB-treated FVD in the TMR. Conclusion: It appears that FVD preserved with SMB can be safely incorporated into TMR as replacement of corn grain without impairment of nutrient metabolism and feed intake.

The purpose of this study was to investigate the dietary behaviors, eating habits, and nutrient intakes of elementary students with atopic dermatitis. Dietary conditions during infancy, dietary regularity, dietary behaviors, eating habits, and daily nutrient intakes were surveyed and compared between children with (WAD) and without (WOAD) atopic dermatitis using the 24-hr recall method. The ratio of children who responded 'I eat regular meals' was significantly lower in the WAD compared to WOAD group (76.4% vs. 81.7%, p<0.05). The ratio of children who answered 'I eat processed foods or fast foods more than once a week' (p<0.01) and 'I take nutritional supplements' (p<0.001) was significantly higher in the WAD compared to WOAD group. The scores for 'I eat milk and its products everyday' (1.4 vs. 1.5, p<0.05), 'I eat dishes fried or stirred with oil more than twice a week' (2.0 vs. 2.1, p<0.05), and 'I eat snacks such as ice cream, cake, snacks, carbonated beverages more than twice a week' (1.9 vs. 2.0, p<0.05) were significantly lower in the WAD group than in the WOAD group. Daily energy intakes were 1,859.1 kcal and 1,829.5 kcal in WAD and WOAD children, respectively, with no significant difference. However, daily intakes of fat (p<0.05), phosphorus (p<0.05), and vitamin $B_2$ (p<0.05) in WAD children were significantly higher than in WOAD children. To sum up, elementary students with atopic dermatitis had irregular eating habits and higher intake frequency of processed or fast foods, milk and its products, dishes fried or stirred with oil, and snacks compared to normal children. Dietary guidance and nutritional education are required to improve irregular eating habits and induce adequate nutrient intakes in children with atopic dermatitis.

Data from 24 feeding trials conducted on lactating cattle from different institutes across India were subjected to regression analysis to derive requirements of ME, TDN, CP and DCP for maintenance, milk production and body weight gain. Maintenance requirements for ME, TDN, CP and DCP were 598 KJ, 39.5 g, 6.27 g and 2.90 g/kg $W^{0.75}$, respectively and the corresponding requirements for production of 1 kg 4% FCM were 5,023 KJ, 332 g, 82 g and 58 g. The corresponding requirements for one g gain in BW were 27 KJ, 1.78 g, 0.44 g and 0.19 g. Regression equations had high $R^{2}$ values (0.67 to 0.90) and the equations (Fvalue) as well as coefficients were highly significant (p<0.001). Regressed values were used to develop feeding standards. Derived values matched well with the actual intake versus performance of animals under diverse feeding conditions. The new standards so derived predicted requirements and intake of nutrients for different production levels better than existing feeding standards; as these are based on a more thorough analysis of a larger database, the new feeding standards will be appropriate for wide use in India.
