The purpose of this study was to examine bowel habits, dietary habits, and nutrient intake of constipated adults, and the effects of prune products on relieving constipation symptoms. Fifty one adults with self-reported constipation (mean age 23 years, range 19-41 years, 10 males and 41 females) participated in this study. After a baseline survey on bowel habits and dietuy habits, participants were asked to consume at least 50 g of prune and 200 ml of prune juice per day during a 4-week period in addition to usual diet. Nutrient intake was estimated by a 24 hour recall at the baseline and once every week by diet records during the intervention. Data were analyzed after classifying the subjects into mild constipation group and severe constipation group by the severity of the symptoms. During the intervention, the subjects with mild constipation consumed 56 g of prunes (about 5.6 fruits) and 200 ml of prune juice, and the subjects with severe constipation consumed 59 g of prunes (about 5.9 fruits) and 207 ml of prune juice. Average intakes of energy, dietary fiber and water of the subjects in the mild constipation and severe constipation group increased during the intervention compared to the baseline. Average dietary fiber intake of the mild constipation and severe constipation groups significantly increased from 12.5 g and 11.6 g at the baseline to 18.5 g and 16.8 g after consuming prune products, respectively. These changes were accompanied by an increase in the number of bowel movements, a decrease of defecation time, a change to a softer stool consistency, and a decrease of abdominal pain during defecation. Seventy two subjects answered that prune products were effective to improve their overall constipation symptoms. Our data show that supplementation of prune products is effective to provide energy, dietary fiber and water, and to relieve constipation symptoms for constipated adults.

The aim of this investigation was to assess the relationship between food habits and nutrient intake in college female students. Nutrient intakes of 149 female subjects aged 19.3 y were determined by using 24-hr recall. The questionnaire included general characteristics and food habits (frequency of breakfast and fast food intake). Body composition was determined by bioim- pedance analysis. Nutrient analysis was performed with Can pro software. Statistics were generated using SAS 9.3 (SAS Institute, Cary, NC). Mean intake of energy, fiber, calcium, potassium. vitamin $B_2$ and vitamin C by the subjects ware below KDRIs. The nutrients for which the largest proportion of subjects showed inadequate intakes (less than the RI or AI) were potassium, calcium, vitamin C and fiber. Subjects that consumed fast food ${\leq}6$ times showed significantly lower intakes of calcium, potassium, fiber, vitamin A, vitamin $B_6$ and vitamin C. Subjects who skipped breakfast more frequently showed significantly lower intakes of energy, carbohydrate, fiber, calcium, iron, potassium, vitamin $B_2$ and vitamin C than subjects who ate breakfast more frequently. This is strong evidence that higher intakes of nutrients such as potassium, fiber, and calcium are associated with increased frequency of eating breakfast or decreased frequency of eating fast food. Low calcium, fiber, and potassium intakes may thus lead to chronic diseases. Nutrition education can be an important facilitator for improving nutrient intakes.

In the present paper, the flow distribution in the hot air drying chamber of a sizing machine was numerically analyzed with respect to the geometries of the intake duct to obtain the more uniform flow distribution in the chamber. The result shows that the velocity distribution in the inlet of the chamber was significantly dependent on the the geometry of the intake duct. The degree of the non-uniformity in the chamber was reduced as the incident angle of the intake duct became to be smaller.

The purpose of this study was to find out the prevalence of constipation nutrition knowledge on dietary fiber and frequency of dietary fiber foods intake of 3rd grade high school girls in Kangnung and Seoul. The total 412 questionnaires were analyzed. Defecation frequency was irregular in 47.6% of the students 21.6% had less than twice a week. Those who were in a hurry during defecation frequency was irregular in 47.6% of the students 21.6% had less than twice a week. Those who were in a hurry during defecation were 57.9% and those spent more than 10 min. for defecation were 21.8% More than half of the students(56.6%) answered to have constipation and 13.8% had taken laxative pills more than once during the last one month period. The nutrition knowledge score was relatively high 7.63 points out of possible 10. Dietary fiber intake scores measured by food frequency questionnaire were 3.78 for fruits 3.71 points out of possible 10. Dietary fiber food intake scores measured by food frequency questionnaire were 3.78 for fruits 3.71 for vegetables and 3.37 for seaweeds meaning taken once a week to 2-3 times per month. For the diagnosis of defecation difficulty a factor called "constipation index" was introduced which was composed of defecation frequency time spending for defecation easiness in defecation and feeling of residue in the intestine after defecation. The Cronbach a coefficient of constipation index was 71. Constipation index was significantly correlated with stress level(p<0.05) haste during defecation(p<.01) and defecation time(p<.01) The higher the stress level the more hurry during defecation and the later the defecation the higher the constipation index. The students who ate more often vegetables and seaweeds had lower constipation index(p<.05, p<.01)05, p<.01)

This study assessed yearly trends of food and nutrient intake among high school students aged 16 to 18 years (n=2,377) using the 2007~2015 Korea National Health and Nutrition Examination Survey (KNHANES). Yearly trends of food or nutrient intake were analyzed via logistic regression analysis. The results showed that consumption of sugars & sweets, and beverages & alcohols was increased rapidly during this period (p<0.0001). Intake of meat & meat products, and fish & shellfish also was increased (p=0.0008). Intake of grains and grain products was increased until year 2011 but declined after 2012 (p=0.0025). Consumption of vegetables, and milk & milk products was decreased (p=0.0395). Intake of protein, fat, thiamin, riboflavin, niacin, and iron was increased (p=0.0445). Carbohydrate energy ratio was decreased, whereas fat energy ratio was increased (p=0.0235). Most nutrient intakes satisfied the dietary reference intakes for Koreans except dietary fiber (19.6~26.2%), calcium (46.9~55.2%) and sodium (more than 221.4%) during this period. There was a significant positive correlation between most food group intakes and most nutrient intakes (p=0.0468). Therefore, it is crucial to increase dietary fiber and calcium intake and decrease consumption of sugars, fats and sodium through diverse eating of food groups to ensure balanced nutrition of subjects.

Chickens subjected to heat stress decrease their heat production by consuming less feed. The lowered feed intake naturally brings about decreased production performance of chicken. The only exception to this is the increased survivability. Birds drink less when they eat less. In hot enviror-mental temperature, chicken need more water for increased heat loss through evaporation an increased urine excretion. Thus, the increased water intake may alleviate the heat stress of chicken. Various electrolytes supplementation to feed or drinking water can alleviate the heat stress of chicken by their effect of increasing water intake. Lasalocid, an ionophorous coccidiostat, was found to have the effect of increasing water consumption of chicken, thereby improving the lowered production performance of heat-stressed chicken. Finally, dietary fiber could be another possible element which can exert beneficial effects on heat-stressed chicken.

This study is to investigate consequent nutrient intake status, influence of body mass index(BMI), and fat distribution on the silk amino peptide(SAP) and dietary fiber supplementation. During 2 months of this research (January to March, 2002), 45 women aged 20yr – 30yr (average age 24.6yr) were selected as subjects. Nutrient intake was investigated by questionnaire, 24-hr recall method. Antropometric assessments of the subjects were investigated by SBIA method(Segmental bioimpedance assay, In body 3.0). The results are as follows: mean body weight 57.7kg, mean body height 161.9cm mean BMI 22.0, and mean food habit score was 8.47. Defecation frequency was increased by dietary fiber supplementation. Frequency of pain during defecation was significantly decreased by dietary fiber supplementation (p<0.01). Feeling of residual feces was significantly improved by dietary fiber supplementation(p<0.001). Status of energy and carbohydrate intakes significantly decreased after dietary fiber supplementation(P<0.05). Body fat and WHR(waist hip ratio) significantly decreased after dietary fiber supplementation(P<0.001), and percent body fat was decreased by dietary fiber supplementation, significantly(P<0.05). Above results of this study show that dietary fiber-added routine diet improves defecation condition, and lessens body fat, percent body fat without losing body muscle. Especially, declination of abdominal fat and WHR were notable. That meant decreased risk factor.

Food intake of birds can be affected by particle size as well as diet composition, In order to investigate whether food intake of diets including excessive amount of phenyalanine(Phe) was influenced by diet types. a series of experiments were conducted in growing chicks and laying hens. Growing chicks significantly decreased food intake in a semipurified excessive Phe diet compared with a semipurified control diet, while laying hens fed a practical diet including excess Phe did not significantly reduce their food intake over a corn starch-substituted control diet. In an attempt to find out whether diet type affects food intake in layers, the semipurified type diet with excess Phe greatly reduced food ingestion, but the effect was delayed in the practical type diet. Moreover, under choice feeding regimes between the Phe and either starch, tyrosine(Tyr) or fiber diets in order to investigate whether the decreased food intake in the presence of an excess of dieary Phe in laying hens is involved in the palatability for the diet, there was no significant difference between Phe and starch diet while a preference for the Phe diet tended to be increased when birds were offered Tyr. Laying hens ingested significantly more the Phe diet than the fiber diet within 1 h after feeding. For supporting the idea that preference for the Phe diet may be affected by manipulating taste sense, an anaesthetic or saline was intramuscularly administered under the tongue just before a choice feeding. Preference for the Phe diet was not significantly different from that for the fiber reference diet within 1 h in the anaesthetized birds while the birds preferred the Phe diet in the saline treated group. It is suggested that because birds are able to select a diet, the decreased food intake induced by dietary excess Phe may be due to the repulsive effect of Phe after ingestion but not the taste of Phe.

This study compared the nutrient intake of obese versus non-obese non-insulin dependent diabetes mellitus (NIDDM) patients for Diabetes Medical Nutrition Therapy. The study was conducted at medical hospitals in Gyeonggi and Seoul from April 2009 to November 2009. Fifty-six adult male NIDDM patients were enrolled and divided into two groups: 36 into an obese group (BMI ${\geq}25$) and 20 into a non-obese group (BMI<25). To conduct this study, anthropometric measurements, and daily nutrient intake of obese and non-obese NIDDM patients were measured. Daily nutrient intake was estimated by 24hr-recall and analyzed by the CAN program. In the results, anthropometric measurements of the two groups showed significant differences in weight and BMI (p<0.001). Daily nutrient intake of the two groups showed no significant differences, except for vitamin E intake (p<0.05). The total energy intake of the non-obese and obese groups were $2,669.9{\pm}964$ kcal and $2,555.4{\pm}803$ kcal, respectively, which were both above 113% of the recommended Dietary Reference Intakes for Korean (KDRIs). Cholesterol and sodium intake were $378.1{\pm}215.6$ mg and $6,478.9{\pm}2755.1$ mg, respectively for the non-obese group. Cholesterol and sodium intake were $308.1{\pm}155.6$ mg and $6,306.8{\pm}2788.9$ mg, respectively, for the obese group. Both groups were above 150% of the recommended levels set by the Korean Diabetes Association (KDA). However, their antioxidant nutrient intake was appropriate. Meanwhile, their fiber intake was $10.7{\pm}5.1$ g and $9.8{\pm}5.2$ g, respectively, which was lower than 40% of the recommended intake set by the KDA. The results show that the nutritional education for obese and non-obese NIDDM male patients must aim to reduce total energy, cholesterol, and sodium intake, while increasing fiber intake. In addition, the factors related to a patient's glycosylated hemoglobin, serum lipids, blood pressure, and weight change must be calibrated for the appropriate energy, fat, cholesterol, sodium, and dietary fiber intake.
