  • An experiment was conducted to investigate effects of fiber source on growth performance, N and neutral detergent fiber (NDF) digestibility, and utilization of energy in chicks fed an isocaloric low-energy diet from 7 to 21 days of age. Two fiber sources, cellulose and corn dietary fiber (CDF), were included in a diet at 10, 20 and 30% at the expense of kaolin, an inert diluent. The CDF contained 76.5% NDF consisting mainly of hemicellulose. The results showed that growth performance, N and NDF digestibility, dietary DE and ME values, energy deposition, and NE for production in birds fed CDF were inferior to those in birds fed cellulose. It can be concluded, from the present study, that chicks can utilize cellulose more efficiently than CDF up to a level of 30%.

  • This study was performed to investigate the influence of dietary fiber, which from whole food on the serum lipid level and bowel function in rats. The fiber sources of experimental diets were prepared by drying and milling of small water dropwort(WD), mugwort(MW), butterbur(BB) and apple(AP). Each fiber sources was mixed at the 15% level of the diet. The level of dietary fiber in WD, MW, BB diets was similar but that in AP diet was slightly low. Male rats of Sprague-Dawley strain were blocked into 5 groups ; WD, MW, BB, AP, FF(fiber free). The animals were fed ad libitum each of experimental diets for 37 days. Food intake of AP and FF groups were than other groups, FF group was lower than other grous in food efficiency ratio. MW group showed highest level in fecal weight and fecal water content and group has the longest transit time compare to other groups. Serum triglyceride level was not significantly different among groups. BB group showed the lowest level in the serum total cholesterol. WD and MW groups showed slightly higher level in the serum HDL cholesterol than other groups. Mucosa weight was not significantly different among groups. The activity of maltase in mucosa of small intestine was highest in FF groups. Absorption rates of calcium were not significantly different among groups. Absorption rate of magnesium was higher in FF group compare to others. And, absorption rates of phosphorus in MW and FF groups were slightly lower than other groups.

  • Rice is the primary main dish of Traditional Korean diet. Although there have been changes in food consumption and nutrient intake among Koreans, traditional dietary pattern is stil dominant among Koreans. Traditional Korean diet has emphasized breakfast, which is the most frequently missed meals in Korea today but important for daily work performance and health. Compared to diets of the U.S. and Greece, Korean diet is high in carbohydrate and low in fat and cholesterol due to low intake of meat. Koreans also consume large amount of plant food, which makes fiber content of diet to be high. However fruit and milk consumption tends to be low in Korea. Koreans use fermented food, including kimchi, very frequently as well as foods cooked and consumed at high temperature and over direct fire. Traditional cooking methods are time consuming which limits the usage among modern city dwellers with working women. Despite the strengths of traditional Korean diets in reducing risk factors of chronic diseases, preservation of the tradition in modern Korean society requires special attention and efforts to make them more adaptable to contemporary life styles.

  • The purpose of this study was to investigate the compliance and need for diet therapy among diabetics and their caregivers. A total of 625 respondents participated in this survey. Appropriate management for long-term blood glucose control and difficult-to-manage cases appeared to be diet therapy, physical activity, medical treatment and folk remedies, in that order. The most important educational avenues for diet therapy were books, magazines and TV, Most respondents were educated in diet therapy within a year after diagnosis and had practiced diet therapy for over four years. The most common diet therapy Practices were food selection and Quantity control. Of the specific problems in practicing diet therapy, time and labor, taste, and meal planning appeared to be equally difficult factors. The prevailing diet therapy skills were controlling food amounts at breakfast and supper, and selecting food for lunch and refreshments. Respondents practicing both skills were about 20% of the participants; this shows the need to improve the current situation. The nutrients most frequently considered in diet therapy practice were simple sugars (sugar and sweet goods) , total fats and cholesterol. Since the perception of the role of dietary fiber among respondents was very low, nutrition education about the importance of dietary fiber and food sources of dietary fiber was needed. Diabetics seemed to be concerned about diabetic menus. Three difficult problems in planning diabetic menus were daily menu planning, patient's preferences, and the calculation of calories. As a means of nutrition counseling, they preferred interviews. The higher the educational status and the lower the age, the higher the preference was for internet or PC counseling. Therefore, it is necessary to develop nutrition educational programs so that diabetics can obtain practical knowledge of diet therapy. Furthermore, it is also necessary to develop additional means of informing diabetics about menu planning, while still considering Korean dietary behavior.

  • The experiment was conducted to determine the effect of different fiber levels on milk production of crossbred Holstein milking cows fed urea-treated rice straw (UTS) as a roughage. Eight cows were allotted into 2 squares of 4 cows each with 4 treatments by a balanced design. The treatments were 17%, 22%, and 24% crude fiber (CF) diets and Thai feeding system (free choice of roughage and 1 kg of concentrates/2 kg of milk) as a control. Body weight change was not significantly different among the treatments during the experiment. Milk production (4% FCM) and milk protein content wee not different among the treatments, but milk fat content was low in the 17% CF group and high in the control group. Cows fed the 17% CF diet consumed less UTS and more concentrates than the others, and consequently total DM intake was not different among the treatments. The feed conversion ratio was significantly higher in the control. Feed cost per kg milk was lowest in the control and highest in the 17% CF diet. The fiber content of the diet would be more than 17%, preferably 22-24% for normally producing Thai crossbred Holstein cows when the UTS was fed as a main roughage source.

  • It is now generally accepted that individuals at increased risk for cardiovascular disease may be identified by certain traits or habbits. The factors such as high blood pressure, elevated blood cholestrol, age, sex and obesity are associated with increseaed frequency of disease. The blood cholesterol level lowering will decrease cardiovascular disease risk. The regression of atherosclerosis can be achieved by lowering the level of circulating cholesterol. Those things are connected with the quantity and quality of protein, fats, carbohydrates, especially soluble and non-soluble fiber, magnesium and calcium. The lipoprotein and lipid metabolism are connected with the lipid transport. The factors on lipid absorption and blood serum lipid pattern of human are exist. The factors have a variety of materials with different chemical and physical properties. The soluble fiber diet make a low blood and liver lipids. Many kind of soluble fiber results in a lowering of blood cholesterol and triglyceride levels. The cholesterol lowering effects of dietery fiber may be a results of alterations of in intestinal handling of fats, hepatic metabolism of fatty acid or triglyceride acid metabolism of lipoprotein. It is investigated that the high density lipoprotein (HDL) is inversely related to coronary artery disease. It has been postulated that HDL may be an important factor in cholesterol efflux from the tissues, therby reducing the amount of cholesterol deposited there. Alternatively, the HDL may pick up cholestyl ester and phospholipid during normal VLDL lipolysis in the plasma. The HDL levels are relatively insensitive to diet. At present time, the cause-and -diet effect of HDL's inverse relation to CHD remains unclear.

  • In patients with functional gastrointestinal disorders, dietary factors have an important effect on the development or worsening of gastrointestinal symptoms. Therefore, nutritional advice is often needed for the treatment of these patients. Although no firm conclusions can be drawn from current studies, the use of low-fat diets can be recommended in patients with functional dyspepsia. Constipation can be treated with a high-fiber diet. There are few studies in irritable bowel syndrome patients with diarrhea. The diet recommendations must be applied to each patient depending on symptoms.

  • 경제발전으로 인해 한국인의 식습관이 점차 서구화됨에 따라 웰빙(Well-being)의 문제가 야기되고 있다. 웰빙은 장내 미생물 군집과 밀접하게 연관되어 있으며, 이는 섭취한 음식에 따라 가변적이다. 이에 본 연구에서는 장내 미생물의 16S rRNA 유전자를 기반으로 하여 MiSeq을 진행하였고, 고지방 식이(HFD) 및 저식이섬유 식이(LFD)로 인한 장내의 미생물 생태 비교 및 분석하고자 수행되었다. 일반 대조군(CTL) 그룹과 비교하여 각각 LFD 그룹과 HFD 그룹은 species richness가 유의적으로 감소하였고, species evenness에서는 차이가 나타나지 않았다. phylum 수준에서는 Proteobacteria는 두 처리군에서 유의적으로 증가하였고(p<0.05), 그 중 Sutterella genus가 유의적으로 가장 많이 증가하였다. Bacteroidetes는 HFD 그룹에서 유의적으로 감소하였고, S24-7 family가 가장 큰 비율로 감소하였다. 한편 Firmicutes는 HFD:LFD 그룹에서 차이를 보였고, LFD 그룹에서 Lachnospiraceae family가 유의적으로 낮은 비율로 나타난 것이 확인되었다(p<0.05). PICUSt 기반 신진대사 분석에서 LFD 그룹은 아미노산 대사 및 탄수화물 대사에 관여하는 미생물 수가 유의적으로 감소하는 양상을 보였고(p<0.05), 에너지 대사에서는 메탄 대사에 관여하는 미생물이 유의적으로 감소하였다(p<0.01). 한편 HFD 그룹에서는 아미노산 대사에 관여하는 미생물 수가 유의적으로 증가하였다(p<0.05). 글리칸 생합성 및 대사에 관여하는 미생물은 LFD 그룹과 HFD 그룹에서 유의적으로 증가하는 것으로 나타났다(p<0.01). 이상의 결과를 통해 지속적으로 불균형한 식단을 섭취하는 것은 장내 환경을 dysbiosis시켜, 대사성 질환 및 장 기능 저하를 유발할 것으로 예상된다.

  • This study examines the effects of a low-calorie raw juice diet on the level of serum ferritin in adults and analyzes nutrient intake from the diet. There were significant differences between juices; the highest calorie was provided by pear juice, highest crude protein, vitamin A, and vitamin B2 levels were from green Juice 1; and highest vitamin C and vitamin B1 levels were from fruit juices. The ratio of estimated energy requirements (EER) for the participants was 56.2% from the raw juice diet. The percentages of recommended intake (RI) from the raw juice diet of protein (57.9%), dietary fiber (19.1%), niacin (6.2%), calcium (0.1%), and magnesium (0.2%) were lower than 75%. However, those of RI of vitamin A, vitamin B1, vitamin B2, vitamin B6, and vitamin C were 1796.5%, 7481.7%, 1915.5%, 30858.7%, and 7500%, respectively, exceeding the tolerable upper intake level (UL) for vitamin A, vitamin B6, and vitamin C. There were significant decreases in weight, the body mass index (BMI), body fat mass, and skeletal muscle mass in males and females. After the diet program, serum iron and SOD (superoxide dismutase) showed significant decreases, whereas RBC, hemoglobin, hematocrit, and serum ferritin showed significant increases. There were negative correlations between serum ferritin and weight and between serum ferritin and skeletal muscle mass for all participants. There were negative correlations between serum ferritin and skeletal muscle mass for males and between serum ferritin and body fat mass for females. These results suggest that a raw juice diet can supplement a regular diet to prevent excess or deficient nutrient intake.
