Objectives: This study examined the effects of nutrition counseling by the nutrition care process (NCP) on diet therapy practice and glycemic control in patients with type 2 diabetes mellitus. Methods: The survey was conducted on 49 patients whose hemoglobin A1c (HbA1c) level ranged from 6.5% to below 10% among patients aged 30~60s with type 2 diabetes mellitus. Nutrition counseling by the NCP process was carried out twice: first nutrition counseling and follow up counseling. The questionnaires were composed of 54 questions in five fields (general characteristics, health-related behaviors, diet therapy-related items, dietary life, diet therapy-related knowledge, diet therapy-related barriers). Nutrition intervention in nutrition counseling was performed based on the individualized diagnosis of NCP. Results: All the subjects practiced self-monitoring of their blood glucose levels, regular exercise, and diet therapy after NCP-based nutrition counseling. Diet therapy-related knowledge and practice by the subjects were improved after nutrition counseling. While the intake of boiled white rice decreased, the intake of boiled brown rice and barley rice in the subjects increased significantly. After nutrition counseling, the weight and HbA1c of the subjects decreased. Conclusions: These results suggest that personalized nutrition counseling by NCP process is effective for diet therapy compliance and glycemic control of type 2 diabetic patients.

This study was designed to observe the effects of both control and atherogenic diets on the cholesterol and triglyceride (TG) in serum and liver of adult rats fed diets supplying two levels of dietary fat and two different sources of dietary protein in early life. For the first experimental period, the rats were assigned into the four diet groups: High fat, casein (HC); High fat, gluten (HG); Low fat, casein (LC): Low fat, gluten (LG). Each group was subdivided into control and atherogenic groups for the second experimental period. Cholesterol and TG were determined in serum and liver after 7 hr fasting. The body weight gain was greater in the rats of the casein groups than those of the gluten groups tut not influenced by the level of the dietary fat. The difference in body weight from the quality of dietary protein in the first period was not disappeared even after the second period. After the first period, higher serum cholesterol was observed in the rats fed either casein or high fat diets. With the second experimental diet, rats fed atherogenic diet showed higher serum cholesterol concentration but lower serum TG levels compared to those fed control diet, regardless the diets fed in the first period. Serum cholesterol level of the rats of both groups which had been fed high fat diets in early life was increased compared to those of the low fat diet groups. This effect was more pronounced with the atherogenic diet groups than control groups. However, no differences were found in serum cholesterol levels resulted from the different types of dietary protein fed in the first period. Serum TG concentration was not influenced by the quality of protein and level of fat in the diet but seemed to be mere affected by the amount of carbohyrates in the diet. Liver cholesterol per unit weight was greater in the gluten diet groups than in the casein groups but total cholesterol was higher in casein fed rats. There were no differences in liver TG among the groups.

The effects of taurine on plasma and liver cholesterol, erythrocyte ouabain sensitive Na efflux and platelet aggregation were examined in Sprague Dawley rats fed control or 0.5% cholesterol with 0.2% cholate diet. Plasma and liver levels of total cholesterol were increased significantly (p<0.05) in rats fed cholesterol diet compared to the control, and taurine significantly decreased the elevated plasma level of cholesterol in rats fed cholesterol diet (p<0.05). HDL-cholesterol was decreased in groups fed the cholesterol diet regardless of taurine supplementation and the difference between groups with and without cholesterol was significant (p<0.01). Plasma triglyceride was decreased and liver triglyceride was increased both significantly (p<0.05) in rats fed cholesterol compared to the control. Plasma and liver triglyceride in rats fed taurine was decreased significantly compared to the control (p<0.05). Intracellular Na tended to be lower in rats fed cholesterol or taurine and higher in rats fed cholesterol plus taurine compared to the control. Na efflux through Na-K ATPase and the passive leak of Na was somewhat reduced in rats fed cholesterol or taurine and was augmented in rats fed cholesterol plus taurine compared to the control, which showed a similar trend to the intracellular Na. Taurine supplementation caused a suppression of Na efflux in groups fed control diet and restored the suppressed Na efflux in groups fed cholesterol. Platelet aggregation was significantly decreased in the group fed taurine compared to the control (p<0.05) and the group fed cholesterol plus taurine was also a little lower in aggregation than the group fed cholesterol. Microscopic examination showed that taurine prevented fatty liver in rats fed cholesterol diet. Taurine known for stimulating Na-K ATPase in some cell types rather decreased erythrocyte ouabain sensitive Na-K ATPase in the present study. Taurine had hypolipidemic and hypocholesterolemic effects and inhibited platelet aggregation which may be favorable for prevention of cardiovascular diseases.

Because of its more complete hydrolysis and rapid absorption, MCT is expected its usefulness in the diets of patients with malabsorption syndrom. Also, several authors reported that serum cholesterol level was lower after MCT feedings. In this study, rate of each experimental group were fed for 4weeks with 20％ MCT, 20％ corn oil, mixed diet of 10％ MCT and 10％ corn oil, mixed diet of 17％ corn oil and 3％ shortening. After experimental diet, it was measured to growth rate and serum cholesterol, triglyceride and phospholipid level. The results were as follows; 1. The body weight gain was the lowest in MCT group and others were lower than control group. 2. Serum total cholesterol level was the lowest in corn oil group and others were significantly lower than control group. Free cholesterol level was lower in all experimental groups than control group too. 3. Serum HDL-cholesterol level was significantly higher in all experimental groups than control group. 4. The ratio of VLDL, LDL-Cholesterol to HDL-Cholesterol was significantly lower in all experimental groups than control group. 5. Serum triglyceride level was higher in all experimental groups than control group. Serum phospholipid level was significantly in only mixed diet group of corn oil and shortening than control group. 6. The ratio of total cholesterol to phospholipid was significantly lower in corn oil diet group than control group.

Objectives: This study was performed to evaluate the effects of fermented Samjung-hwan (SJH) extracts on weight, serum lipids and blood glucose. Methods: SJH was fermented using three different probiotic bacterial strains (Lactobacillus plantarum [LP], Leuconostoc mesenteroides [LM], Bifidobacterium longum [BL]) separately. Thirty-six rats were divided into normal, control (high fat diet), SJH-UF (high fat diet+unfermented SJH 200 mg/kg), SJH-LP (high fat diet+LP fermented SJH 200 mg/kg), SJH-LM (high fat diet+LM fermented SJH 200 mg/kg) and SJH-BL (high fat diet+BL fermented SJH 200 mg/kg). For 8 weeks later, we examined body weight, total cholesterol, high-density lipoprotein (HDL)-cholesterol and blood glucose. Results: The control group showed significantly increased weight gain compared with normal group and SJH-LP and BL groups had less weight gain than control group, significantly. In the lipid serum tests, control group showed significantly increased total cholesterol levels compared with normal group and only SJH-LP represented decreased total cholesterol levels compared with control group. However there was no significant change in the HDL-cholesteol levels. In the blood glucose tests, that of control group significantly incereased more than that of normal group, SJH-BL showed significantly decreased blood glucose levels compared with control group. Conclusions: SJH-LP, SJH-BL showed weight control effect, SJH-LP decreased TC and SJH-BL reduced blood glucose.

The purpose of this study was to find the effect of honey on the sugar metabolism In Sprague-Dawley rats. All experimental rats were fed ad libitum, for seven weeks, 68% saccharide diet anti 10% or 20% honey from acacia, sumac and miscellaneous flower honey, respectively, and sucrose. The amount of glucose in whole blood was increased in all groups fed with honey except the group fed with 10% sumac honey solution. The amount of fructosamine in serum of rat taken diet with honey solution was increased in comparison with normal group, control group, sucrose group. The amount of fructosamine in serum of rat taken diet with honey solution was high in order of sumac honey > miscellaneous flower honey > acacia honey. The amount of lactate and pyruvate in whole blood of rat taken diet with sucrose group or honey group were decreased in comparison with the normal group and control group. The amount of $\beta$-hydroxybutyrate in serum of rat taken diet with sucrose or honey was increased in comparison with the normal group, control group.

Two experiments were conducted to investigate into the effects of replacing maize with a mixture of cassava root and leaf meal (CRLM) on the performance of broiler chickens. In experiment 1, CRLM replaced 50 or 100 percent of maize in the control diet. In experiment 2, the 100 percent CRLM based-diet was fortified at a further 3 percent level with coconut oil. A total of 180, one-day old Shaver Starbro chicks, raised up to 49 days of age, were used. There were no significant (p<0.05) differences in final body weights, feed intake and feed efficiency between the control group and the group fed the diet in which 50 percent of the maize was replaced with CRLM. At the 100 percent level of replacement of maize with CRLM, however, final body weights, feed efficiency and carcass yields, were significantly (p<0.05) reduced. Dressing percentage and feed intake were not affected (p>0.05) by level of substitution of maize with CRLM. In experiment 2, when the diet in which all of the maize was replaced with CRLM was fortified with coconut oil at an additional 3 percent level, broiler performance improved and equaled (p=0.05) that obtained on the control maize diet. It was concluded the CRLM can replace 50 percent of maize in broiler diet without adversely affecting performance. However, for the complete replacement of maize with CRLM, it is necessary to further supplement such a diet with a high energy density ingredient if broiler performance is to be maintained.

The nutrients such as protein, calcium, iron and all three of them, either by natural or chemical substances were added to the recipes of yeast breads. Acceptability test was carried for the each formulated bread before selecting eight experimental diets. Sixty albino rats were separated into ten dietary groups including eight enriched breads and two control diets of plain breads from the market, which were used as the carbohydrate sources of the each basal diet. Experimental regime was seven weeks. The growth rate, hematology, total serum protein and organ weights we compared. Generally animals on the enriched bread showed the better growth rate than the rats fed control diet. Diet H enriched protein, iron and calcium by natural foods, brought up the highest weight gain among all of the rats. Hemoglobin concentrations of the rats on the diet H and G (enriched with three nutrients by chemicals) were 14.3 and 14.2 gram % comparing with other two control groups (12.9 and 13.1 gram%). Rats on diet K (fed nothing but diet H enriched bread) showed the significantly higher growth rate, total serum protein and hemoglobin level than these on the diet L (fed only plain bread from the market).
