Hypertension is prevalent among older adults, and nutrition is important for hypertension management. However, there are few nutrition education materials developed for older adults. The purpose of this study was to develop a booklet for prevention and management of hypertension for older adults. Based on lesson plans, topics for the booklet included introduction to hypertension, hypertension prevention through weight management, nutritional management of hypertension, and lifestyle modifications. After several revisions of the draft were made, illustrations and icons appropriate to the text were designed by a graphic designer using Illustrator 9.0 and Photoshop 6.0. The booklet consisted of four chapters and 40 pages. The first chapter dealt with information on hypertension, risk factors, complications and dietary guidelines. These were mainly explained by illustrations and characters of older adults. The second chapter included assessment of obesity, reducing fat intake and behavioral change strategies. The third chapter focused on practical tips for reducing salt, eating more fiber and calcium, and sample menus. The fourth chapter presented information for quitting smoking and drinking, and stress management. Finally, games, meal planning and quizes, were presented as reinforcement. Based on pilot testing with 10 adults aged 50 and older, minor changes were made in wording, expressions and information. This booklet is characterized by using simple and specific messages, providing tips for dietary and lifestyle changes, and using illustrations and characters of older adults to increase understanding. The revised booklet is self-explanatory and can be used by older adults or in nutrition education for older adults.

The purpose of this study was to investigate the food habits, dietary intakes and GTTs (glucose tolerance tests) of female college students according to BMI in the Kyunggido area. Questionnaire surveys, 24 hr dietary recalls, and GTTs were conducted with 108 students (36 under-weight students, 42 normal weight students, and 30 over-weight students). The results were as follows: The under wt. and over wt. groups had lower frequencies of eating breakfast but higher frequencies of eating lunch than the normal wt. group. The ratio of students having dinner everyday was low in the order of under wt. > normal wt. > over wt.. The over wt. group skipped breakfast mainly due to lack of time and the need to get to school, and the under wt. group had a high ratio (48.1%) of lunch skipper as a result of having brunch. The over wt. subjects had poor habits of eating fast and overeating, but the under wt. students ate their meals slowly. The under wt. group had a high ratio of students who ate snacks and fast-food. All subjects wanted to immediately improve their poor habit of overeating. Plant oil, animal Fe, and vitamin E intakes were lower in the under wt. group than in the other groups. For the GTT, the over wt. students had significantly lower blood glucose levels after 30 min. than the other groups. BMI was negatively correlated with blood glucose level after 30 min, but positively correlated with crude fiber, ash, Ca, plant Ca, P, animal Fe, Na, K, $\beta$-carotene, vitamin $B_6$, niacin, and vitamin E.

To evaluate the school lunch program served by elementary schools in Muan, Korea, we examined children's preference for the dishes offered on the menus. School lunch program menus showing the food composition of 400 meals (100 meals in each season) were collected. The serving frequency of each dish on the menus was counted. Eighty-seven representative dishes were selected based on the serving frequency and preference for each dish was determined by a survey of 414 elementary school students who were served by the school lunch program. We also analyzed the nutrient contents of each representative dish. Among the prepared foods, children indicated the highest preference for desserts. Steamed rice was served more frequently as a main course than one dish meals, although children preferred one dish meals to steamed rice. Among side dishes, those that were deep-fried were the most preferred. Children indicated high preference for fruits, milk, and eggs, and low preference for fish and clams, vegetables, and beans. The serving frequency with which main courses, soups, and side dishes were served showed no correlation with children's preference for each. Preference for dishes correlated positively with nutrient contents of calories and lipids, but negatively with nutrient contents of fiber, calcium and vitamin A. According to these results we can suggest that dietitian should consider children's preference into greater consideration to increase menu acceptability and thereby reduce waste. Children need to be educated about the roles and contents of nutrients in food and the fact that preference for foods affects nutrient intake.

This study was conducted to investigate the anthropometric data, bone density, serum profiles, nutrient intakes and diet quality of premenopausal and postmenopausal women. For the study, we obtained data for analysis from the combined 2008~2011 Korean National Health and Nutrition Examination Survey (KNHANES). The height and weight were 157.8 cm and 58.7 kg in premenopausal women and 155.5 cm and 58.3 kg in postmenopausal women, respectively. The obesity rate was 27.49% in premenopausal women and 34.98% in postmenopausal women (p<0.001). Total cholesterol, LDL-cholesterol, triglyceride, GOT, GPT and alkaline phosphatase in postmenopausal women were significantly higher than those in premenopausal women (p<0.001). The prevalence of osteoporosis was 0.0~0.89% in premenopausal women and 0.48~13.22% in postmenopausal women (p<0.001). In postmenopausal women, rates of hypertension, stroke, myocardial infarction, depression, and diabetes were significantly higher than those in premenopausal women. Water, fat. ash, sodium, retinol, thiamin, riboflavin and niacin intakes in premenopausal women were significantly higher than those in postmenopausal women. Water, fiber, Ca, and, K intakes were below KDRIs (Dietary Reference Intakes for Koreans) in both groups. The mean adequacy ratio (MAR) of premenopausal women was higher than that of postmenopausal women (p<0.001). The index of nutritional quality (INQ) in premenopausal women was also higher than that of postmenopausal women except iron and vitamin C. Therefore dietary guidelines and an education program should be developed for desirable improvement of health, bone density, nutrient status and dietary quality of postmenopausal women.

This study investigated the effects of insoluble dietary fibers from pine (Pinus radiata D. Don) inner bark powder (PIBP) on loperamide constipation in rats. Male Sprague-Dawley rats were administered PIBP in their diets at concentrations of 5% and 10% for 4 weeks. Rats were divided in to four groups, normal diet group (Cont), a normal diet and loperamide group (Lop), 5% PIBP experimental diet and loperamide group (Lop+PIBP 5%), and 10% PIBP experimental diet and loperamide group (Lop+PIBP 10%). Constipation was induced by oral administration of loperamide (2 mg/kg, twice per day) for the last three days of the experiment. Food intake, body weight, properties of feces, gastrointestinal transit time, and serum lipid profiles were measured. When compared with the normal diet and loperamide group (Lop), there were increases in fecal pellet number (p<0.05), wet weight (p<0.001), and water content (p<0.001). Positive results were derived from relevant indicators to improve constipation. In addition, the number of fecal pellets in the colon was not significant, and decreased as PIBP content increased. PIBP had a concentration-dependent effect on reduction of total cholesterol, LDL-cholesterol, and triglycerides and elevation of HDL-cholesterol. These results indicate that PIBP may effectively prevent constipation.

Distillers dried grains with solubles (DDGS) is a by-product from processing corn to produce bio-ethanol, and it contains almost three times higher protein, fat, and fiber than corn. Intake of higher amount of nutrients originated from corn in lactating sows may contribute to changes in milk composition and thus alter the growth of suckling piglets. Therefore, the objective of this study was to evaluate effect of supplementing DDGS in the diet of lactating sows on variation in the body weight of piglets. A total of 50 sows with parities of 3 to 5 were usedand allottedinto one of four treatments which included 0 (CON), 10% (DDGS10), 20% (DDGS20), or 30% (DDGS30) DDGS in the diet. Diets were fed to sows during the whole lactation period. Individual body weights of piglets were measured within 24 h after farrowing and at weaning. No significant differences were observed inthe coefficient of variation (CV) for body weight of piglets within a litter after farrowing and at weaning among the treatments (p>0.05). There was, however, a tendency of decreases in the CV for body weight of piglets within a litter at weaning compared with that after farrowingin the DDGS10 and DDGS20 treatments. At weaning, the percentage of the number of piglets weighing less than 4.5 kg in DDGS20 (4.86%, 7 out of 144; p<0.05) or DDGS30 (5.04%, 6 out of 119; p=0.059) was lower than that in CON (12.41%; 17 out of 137) although this pattern was not observed in DDGS10. In conclusion, addition of DDGS in lactating sow diets improved piglet performance by reducing the number piglets weighing less than 4.5 kg.

The purpose of this study was to compare the consciousness health status and food habit for farmers in Korea. Eight hundred persons were surveyed by rural leader of RDA, composed with 35.1% of male and 64.9% of female. Data collection includes height weight and blood pressure by measuring method and personal & family situation by interview for influential factor of health status and food habit. The questionnaire was included dietary habit of salt, sugar, dietary fiber and fat intake and other behavior questions related with diet. The subjects were composed 32.5% of elementary school graduated and 50% of middle size farming. Of the all subjects, 54% of were rice planted farming mainly and 19 were over 65 year-aged group. In the concept of disease prevalence. gender difference was exist, liver and heart complains were more frequency in male and waist pain and urinary complain in female, shoulder pain and nervousness were frequently prevalent to all group of farmers. The hypertension prevalence of farmers were 16% by measuring blood pressure, but consciousness of hypertension was very low (5%). The correlation of health status with personal factors were analysed, body weight, number of family, education level, and working level were significant with CMI score and Farmers' syndrome score. The food habit status was negatively correlated with weight and BMI, age was negatively correlated with CMI score and farmers' syndrome. The consciousness of health status and food habit score were significantly correlated with smoking and alcohol drinking. It concludes that good food habit contribute wellness of health. Nutrition education for better food habit would be helpful on health status.

The purpose of this study was to investigate effects of the developed nutrition education program focused on individual daily energy requirements and food exchange units using Food Exchange System for diabetes mellitus at a community health center. Developed the nutrition education program, four weeks' nutrition education including provided twice individual meal as diet therapy (2 hour/lesson/week, 4 week), was provided to 20 diabetic elderly (12 male, 8 female, 50-75 yrs): 1st lesson "Introduction: management of diabetes mellitus", 2nd lesson "6 Food groups and sources of 6 food groups", 3rd lesson "Individual daily energy requirements and food exchange units", and 4th lesson "Food choice for diabetes mellitus". For effects' analysis of the developed program, we assessed the changes in anthropometric characteristics; biochemical characteristics and nutrient intakes using 24 hr recall method. Effects of the developed nutrition education program were as follows: weight was significantly decreased, blood urea nitrogen (BUN) and glycosylated hemoglobin (HbA1c) were significantly decreased, and distribution of subjects in BUN and HbA1c was significantly changed. In protein : fat : carbohydrate (PFC) ratio, it was significantly changed from 15.98 : 16.30 : 66.69 to 17.51 : 18.94 : 64.10. In evaluation of nutrient intakes by Dietary Reference Intakes for Koreans (KDRI), protein, fiber, fat, vitamin E, niacin, folic acid, calcium and zinc were shown significantly positive changes in distribution of subjects according to intake level. The index of nutrition quality (INQ), nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) were significantly increased. In conclusion, the developed 4 weeks' nutrition education program focused on individual daily energy requirements and food exchange units using Food Exchange System for diabetes mellitus at community health center may improve the symptom of diabetes mellitus.

In other to investigate the hypolipidemic effect of dry edible leaves on serum lipids, four kinds of powdered leaves(persimmom, mulberry, perilla, and soy bean) were added to experimental diets at the levels of 5%(w/w). The diets were fed to 30 male Sprague-Dawley rats, aged 4 weeks and weighing 60$\pm$5g, for 3 weeks. Food intake was the largest in Group 1(control), with 5% of cellulose powder, while food efficiency was the highest in Group 2(persimmon). Total cholesterol level in serum was lower in Group 5(soybean) and Group 4(perilla) than the other groups. In comparison with Group 1, HDL-cholesterol level was very high in Group 4 and atherogenic index was low in Groups 4 and 5. Free cholesterol level was the highest in Group 2, and was the lowest in Group 1. Both LDL and LDL-cholesterol levels were the lowest in Group 1, while they were very high in Groups 2 and 3(mulberry). Triglyceride level was the lowest in Group 4, and the highest in Group 1. Except Group 3, all groups had lower phospholipid level than Group 1. Compared with Group 1, calcium level in serum was low in Groups 3, 4 and 5, magenesium level was low in Groups 2, 3 and 5, phosphate level was high in Group 4, and iron level was exceptionally low in Groups 4 and 5. In conclusion, Group 4(perilla) and Group 5 (soybean) showed a favorable effect in atherogenic index and serum levels of various lipids.
