Almost all Korean women in rural area breast feed their children for average 18 to 24 months. Since they breastfeed their children for long period the need for the lactating mot­hers to be nutritionally refurnished becomes evidently great. However the studies on the nutrient intake level of these mothers has been very scarce. We have studied the food and nutrient intake level of 93 lactating women randomly selected from rural areas of South Korea. Thirty one well trained and experienced surveyors conducted the dietary survey by the. combination method of precise weighing and interview for two 'consecutive days. Briefly stating the findings 1) The dietary pattern of the lactating women in rural Korea was not different from the ordinary Korean diet-i.e no conscientious effort to improve the quality of the diet was apparent. 2) Consequently over 90% of the total food intake was made up with the typical rice­kimchi diet. 3) The quantity of the total food intake was greater than the national average sufficient intake of calorie was observed. 4) No milk or the milk products were consumed by the lactating women in rural Korea. 5) Average intake of protein was 88 grams. Only 5% of these was provided by the animal foods. 6) Mean daily intakes of niacin, thiamin and ascorbic acid exceeded the recommended allowances. But vitamin A intake was 1171 IU-about 33% of the RDA-and the riboflavin intake was 0.92 mg. which is about 54% of the recommended level for the lactators. 7) Average calcium intake was 490 mg.-41% of the RDA. The iron intake was adequate.

The purpose of this study was to investigate whether nutrition counseling and exercise could be beneficial to patients with acquired cardiac disease (ACD). Twenty-five ACD patients participated in this program, which was based on guidelines for serum lipid management. To measure the effects of the nutrition counseling and exercise education, outpatients with ACD were selected and randomly assigned to three groups which were a control group, a diet only group and a diet and exercise group. Nine diet only group patients and nine diet and exercise group patients received nutrition counseling or nutrition counseling and exercise education every other week. Patients who served as a non counseled control group did not receive any counseling during the same study period. Various markers of disease risk, including lifestyle, anthropometric indices, eating behaviors, and serum lipid levels were measured before and after the program. The program lasted up to 12 weeks, depending on the individuals involved. Database management and statistical analyses were performed using SPSS 7.5 software. As a result, BMI and %IBW showed decreased trends in the diet only and the diet and exercise group. Food habit scores were significantly increased in the diet only group and the frequency of saturated fatty acid, dietary cholesterol, salty food and instant food intake were decreased in the diet only group. Comparisons of the daily nutrient intakes of the groups showed their total calorie, carbohydrate and protein intake had decreased significantly, and also the total fat and dietary cholesterol intake had decreased in the nutrition counseling group. The serum total cholesterol and LDL-cholesterol decreased after 12 weeks in the nutrition counseling group. The diet and exercise group showed less interest in diet control than the diet only group. These results show that a well-planned nutrition counseling program would reduce the risks of ACD and cardiovascular disease and help to care such diseases.

The trial was conducted to assess the impact of consulting through telephone on body weight reduction among 18 obese adult women. The degree of obesity, food intake pattern, and life style were examined through phone calls. Subjects visited our clinic and their body fat percentages were measured using impedance fat meter (model SIF-891), and were recommended and recorded to have a low calory diet with changes in the food habit and behavior. The study results are as follows: 1. There is a positive relationship between food habit, lifestyle, obese degree, and fat percentage. 2. 8-10kg and 5kg reductions in the body weight were observed among 14 subjects and 2 subjects, respectively. However, 2 subjects maintained their body weights. 3. The body reduction curve looked like a stairway (type) with low slope and was related with food intake amount. 4. It was possible to have the adequate protein intake only through the vegetable diet. 5. 15 out of 18 subjects were on the prescribed low calory diets for 3 days. Therefore, there is a time limitation to follow the diet treatment. 6. A body weight reduction altered dietary intake of foods which were rich in sweet taste, and the favorite foods were chocolate and candy.

To evaluate the nutritional values of Spirulina platensis as the protein supplement for laying heo diet, two experimental diets (Control, Spirulina platensis 2%) were prepared. Total 120, 40-wk old ISA Brown layer hens were randomly employed with 15 hens per replicate and 4 replicates per treatment. Hen-day egg production, egg weight, feed intake, intake /egg weight, egg shell thickness, yolk color score and yolk cholesterol content were examined during 6 weeks of experimental period. Hen-day egg production and feed conversion ratio (intake /egg weight) were significantly (P<0.01) improved by the 2% Spirulina plalensis supplementation. However, there were no differences in egg weight and feed intake between hens fed two experimental diets. Egg from hens fed Spirulina platensis 2% diet have more yellowish yolk color than the control egg although there was no difference in egg shell thickness. Yolk cholesterol content was significantly (P

Obesity is caused by imbalance of energy intake and expense. If energy intake is more than its expenditure, body does fat accumulation and affects body weight. It can be fetal disease although obesity is not disease in itself. Central regulatary system is affected by many neurotransmitters regulating .food intake in brain. Hypothalamus was known as one of food intake regulation in CNS. In order to investigate gene expression difference in hypothalamus by different nutrient, we used C57/BL6 control mouse and db-/db- mouse. They divided each of two group with mouse, and fed control diet and high-fat diet for 4 weeks. Each of control and high-fat diet contained 11.7% and 59.7% fat, respectively. Then we performed microarray assay with them. We compared among changed genes in hypothalamus region. In the results, we observed that increased genes were more than decreased genes. Although hypothalamus size of db-/db- mouse is smaller than that of C57/BL6, more genes were affected in db-/db- mouse. In this study, many genes are affected by nutrient in hypothalamus region.

This study was carried out investigate the effects of dietary addition of mineral and sugar on the dry matter intake, daily gain, yield grade and quality grade of Hanwoo (Bos taurus coreanae) steers. Three diets fed to steers included a control diet (concentrate mix and rice straw : C) and two treatments diet (control diet + black sugar 100 g + mineral 100 g : T1, and control diet + black sugar 150 g + mineral 50 g : T2). The results are summarized as follows; total feeding intake, body weight gain and daily gain did not show significant differences among the three treatments. Cold carcass weight was significantly (p<0.05) higher in T2 than in the other two treatments (C and T1). There was no significant difference in yield traits of back fat thickness, longissimus muscle area and yield grade among the three treatments (C, T1 and T2). Marbling score showed significantly (p<0.05) higher in order of T2 (5.67) > T1 (4.67) > C (3.67). Meat color, fat color, texture and maturity were no significant difference. Quality grade was higher in T2 than in the other two treatments (C and T1), but there was no significant difference. The results show that marbling score and quality grade of Hanwoo can be increased by high dry matter intake with feeding addition of mineral and sugar.

This study was designed to determine changes of nutritional status, diabetic indices and serum lipid composition in non-insulin dependent diabetes mellitus patients during intake of diabetic-oriented convenience food prepared from 7 medicinal plants and chicken. We conducted dietary, anthropometric and biochemical assessments before and after the intake of diabetic oriented food. Once a day, in the study, their normal lunch was replaced by the diabetic-oriented convenience food diet for 30 consecutive days. It was found that the nutrients of the diet were well-balanced, and the intake levels nearly approached those of the RDA. Obesity rate, body fat, and body weight were significantly lower than those of a normal diet. The average fasting blood glucose significantly decreased while the insulin level significantly increased after the intake of diabetic meal. Also the total serum cholesterol and triglyceride levels significantly decreased. The above results indicate that diabetic-oriented convenience food prepared from 7 medicinal plants and chicken may be used as a diet regime fer controlling the diabetes mellitus on a regular basis.

Objective: Native plants can be used as additives to replace antibiotics to improve ruminant feed utilization and animal health. An experiment was conducted to evaluate the effects of Gentiana straminea (GS) on nutrient digestibility, methane emissions, and energy metabolism of Simmental calves. Methods: Thirty-two (5-week-old) male Simmental clves, with initial body weight (BW) of 155±12 kg were fed the same basal diet of concentrates (26%), alfalfa hay (37%), and oat hay (37%) and were randomly separated into four treatment groups according to the amount of GS that was added to their basal diet. The four different groups received different amounts of GS as a supplement to their basal diet during whole experiment: (0 GS) 0 mg/kg BW, the control; (100 GS) 100 mg/kg BW; (200 GS) 200 mg/kg BW; and (300 GS) 300 mg/kg BW. Results: For calves in the 200 GS and 300 GS treatment groups, there was a significant increase in dry matter (DM) intake (p<0.01), average daily gain (ADG) (p<0.05), organic matter intake (p<0.05), DM digestibility (p<0.05), neutral detergent fibre (NDF) digestibility (p<0.05), and acid detergent fibre (ADF) digestibility (p<0.05). Dietary GS supplementation result in quadratic increases of DM intake (p<0.01), ADG (p<0.05), NDF intake (p<0.05), and ADF intake (p<0.05). Supplementing the basal diet with GS significantly increased nitrogen (N) retention (p<0.001) and the ratio of retention N to N intake (p<0.001). Supplementing the basal diet with GS significantly decreased methane (CH₄) emissions (p<0.01), CH₄/BW^0.75 (p<0.05) and CH₄ energy (CH₄-E) (p<0.05). Dietary GS supplementation result in quadratic increases of CH₄ (p<0.01) and CH₄/DM intake (p<0.01). Compared with 0 GS, GS-supplemented diets significantly improved their gross energy intake (p<0.05). The metabolizable energy and digestive energy intake were significantly greater for calves in the 100 GS and 200 GS calves than for 0 GS calves (p<0.05). Conclusion: From this study, we conclude that supplementing calf diets with GS could improve utilization of feed, energy, and N, and may reduce CH₄ emissions without having any negative effects on animal health.
