The dramatic increase in colorectal cancer incidence in the population of East Asia indicates that diet and lifestyle play a role in colorectal cancer risk. Colorectal cancer prevention and etiologic studies have long provided dietary modification strategies for colorectal cancer prevention. In this review, we provide an overview of the epidemiologic evidence on the association between diet and colorectal cancer risk. Several cohort studies and a few intervention studies, most conducted in Western countries, have shown a possible link between red and processed meat, alcoholic beverages, calcium, vitamin D, vitamin B and the Western dietary pattern with colorectal cancer development. For colorectal cancer prevention in both Western and Asian populations, dietary modification is a key component of colorectal cancer prevention.

The effect of mecadox, trade name of carbodox, in the treatment of colibacillosis and in the prevention of experimental Salmonella infection in swine was studied throughout the experimental period of four weeks using a total of 70 piglets. The results obtained are as followings. 1. Mecadox was found moderately effective as a therapeutic for colibacillosis of piglets when administered orally as pig doser or added to the feed at the ratio of 50 ppm with or without the addition of vitamin A and $D_3$. 2. In the prevention of experimental infection with Sal. choleraesuis, mecadox was found highly effective. As judged by clinical symptoms such as diarrhea and fever together with the confirmation of excretion of the causative organisms in the feces, the best result was obtained with mecadox pig doser followed by mecadox (50ppm) with vitamin A and $D_3$, and mecadox (50 ppm) without the vitamins in the descending order of effectiveness.

우유 중에는 여러 종류의 생리활성물질과 우리 몸에 꼭 필요한 비타민이 매우 소량 함유되어 있어, 그 강화를 목적으로 유가공 산업의 발전과 더불어 다양한 비타민 강화우유가 소개되고 있다. 이에 본 연구에서는 가공 처리 및 비타민 강화 방법에 따른 비타민류의 손실율을 조사하였다. 실험 결과, UHT 처리 후에 비타민 C는 60~70% 가까운 손실율을 보였으며, 비교적 열에 안정하다고 알려진 지용성 비타민인 비타민 D$_3$와 비타민 E도 30~40%의 손실율을 보여 주었다. 이에 반해 비타민을 캡슐 형태로 강화하였을 경우에는 수용성 비타민의 손실율은 상대적으로 매우 낮음을 알 수 있었다. 이는 캡슬에 의해 열뿐 아니라 산소, 빛 등이 효과적으로 차단되어 비타민의 손실이 최소화된 것이라 생각된다. 따라서 열처리에 의한 시유 및 강화우유 중의 비타민의 손실을 최소화하기 위해서는 우유의 살균 온도 및 시간, 강화제 첨가 방법 등에 대한 지속적인 연구가 이루어져야 할 것으로 사료된다.

This study was aimed to investigate the nutritional status and the role of diabetes mellitus in hemodialysis (HD) patients. Anthropometric, biochemical, and dietary assessments for HD 110 patients (46 males and 64 females) were conducted. Mean body mass index (BMI) was $22.1\;kg/m^2$ and prevalence of underweight (BMI<$18.5\;kg/m^2$) was 12%. The hypoalbuminemia (<3.5 g/dl) was found in 15.5% of the subject, and hypocholesterolemia (<150 mg/dl) in 46.4%. About half (50.9%) patients had anemia (hemoglobin: <11.0 g/dL). High prevalence of hyperphosphatemia (66.4%) and hyperkalemia (43.5%) was also observed. More than 60 percent of subjects were below the recommended intake levels of energy (30-35 kcal/kg IBW) and protein (1.2 g/kg IBW). The proportions of subjects taking less than estimated average requirements for calcium, vitamin $B_1$, vitamin $B_2$, vitamin C, and folate were more than 50%, whereas, about 20% of the subjects were above the recommended intake of phosphorus and potassium. Diabetes mellitus was the main cause of ESRD (45.5%). The diabetic ESRD patients showed higher HMI and less HD adequacy than nondiabetic patients. Diabetic patients also showed lower HDL-cholesterol levels. Diabetic ESRD patients had less energy from fat and a greater percentage of calories from carbohydrates. In conclusion, active nutrition monitoring is needed to improve the nutritional status of HD patients. A follow-up study is needed to document a causal relation between diabetes and its impact on morbidity and mortality in ESRD patients.

This research was conducted to compare the effects of vitamin E (VE) when supplemented in either feed or water on the performance and meat quality of broilers. For a six-week feeding trial, a total of 330 broiler chicks were allotted to five treatments. The treatments were 1) 0 ppm VE, 2) 10 ppm VE in feed, 3) 20 ppm VE in feed, 4) 5 ppm VE in water and 5) 10 ppm VE in water. During the starter phase (0-3 weeks) chicks on non-supplemented groups grew slower (p<0.05) than the supplemented ones and the same trend was followed during the finisher (4-6 weeks) and overall period (0-6 weeks). The feed intake was significantly higher in feed supplemented groups as compared with water-supplemented groups and at higher levels as compared with lower levels of supplementation. The nutrient digestibility studies conducted after 15 and 35 days on the feeding trial showed that the digestibility of all nutrients was significantly (p<0.05) higher in supplemented groups than the non-supplemented one. The dressing percentage was higher in supplemented groups, when fed in feed and at higher levels when compared with their respective counterparts. Similar trends were noticed with respect to bone resistance. The calcium and phosphorus contents in tibia were also significantly (p<0.05) higher in supplemented, feed fed groups at higher levels than other groups. The TBARS values measured after 5 and 10 days of storage, which reflect the degree of oxidation, showed significantly lower levels in supplemented diets. The plasma and muscle vitamin E levels also showed a positive linear correlation with the levels supplemented both in feed and water. Overall it can be inferred that supplementation of VE was beneficial and there was not much difference observed when fed either in feed or water at the levels measured in the present study.

The milk product is one of the major foods which provide calcium for nutritional requirement. In addition to calcium, it supplies diverse nutrients including protein, potassium, vitamin A, vitamin $B_1$, and vitamin $B_2$. Adequate calcium intake throughout lifetime ensures optimum bone density and prevents osteoporosis in old age by reducing loss of bone mineral during growth and aging. The nutritional deficiency of calcium intake and spreading of osteoporosis in Korean population accentuated necessity of adequate calcium intake through milk consumption. Obstruction of milk consumption due to lactose intolerance should be overcome by educational programs for adequate milk consumption and low-lactose milk product developments. Consumption of milk products was reported to prevent high blood pressure in clinical studies and epidemiological investigations. As the feeding of milk increased, the body weight and fat of animal decreased in animal studies. The epidemiological investigations revealed that there was a negative correlation between the amount of milk consumption and the body fat. When calcium was provided as dietary supplement in the clinical trials, the body weight and body fat of subjects decreased. When calcium was particularly supplied as a part of milk, the body weight reduction rate was augmented. Calcium, vitamin D, and conjugated linoleic acid have been reported to exert a role in reducing cancer. The paramount importance of milk in nutrition as a source of calcium and other invaluable nutrients emphasizes consistent supply of milk products to adults as well as adolescents by dairy industry.

Purpose: Previous studies suggest that the concentration of 25-hydroxyvitamin D [25(OH)D] in cord blood may show an inverse association with respiratory tract infections (RTI) during childhood. The aim of the present study was to examine the influence of 25(OH)D concentrations in cord blood on infant RTI in a Korean birth cohort. Methods: The levels of 25(OH)D in cord blood obtained from 525 Korean newborns in the prospective COhort for Childhood Origin of Asthma and allergic diseases were examined. The primary outcome variable of interest was the prevalence of RTI at 6-month follow-up, as diagnosed by pediatricians and pediatric allergy and pulmonology specialists. RTI included acute nasopharyngitis, rhinosinusitis, otitis media, croup, tracheobronchitis, bronchiolitis, and pneumonia. Results: The median concentration of 25(OH)D in cord blood was 32.0 nmol/L (interquartile range, 21.4 to 53.2). One hundred and eighty neonates (34.3%) showed 25(OH)D concentrations less than 25.0 nmol/L, 292 (55.6%) showed 25(OH)D concentrations of 25.0-74.9 nmol/L, and 53 (10.1%) showed concentrations of ${\geq}75.0$ nmol/L. Adjusting for the season of birth, multivitamin intake during pregnancy, and exposure to passive smoking during pregnancy, 25(OH)D concentrations showed an inverse association with the risk of acquiring acute nasopharyngitis by 6 months of age (P for trend=0.0004). Conclusion: The results show that 89.9% of healthy newborns in Korea are born with vitamin D insufficiency or deficiency (55.6% and 34.3%, respectively). Cord blood vitamin D insufficiency or deficiency in healthy neonates is associated with an increased risk of acute nasopharyngitis by 6 months of age. More time spent outdoors and more intensified vitamin D supplementation for pregnant women may be needed to prevent the onset of acute nasopharyngitis in infants.
