The purposes of this study were to investigate the characteristics of lifestyle and dietary habits of the colorectal cancer patients in Daegu and Kyungpook areas and to collect the data useful for nutrition education for the prevention of colorectal cancer in this community. The case subjects of the study were 123 patients diagnosed recently as colorectal cancer at Kyungpook National University Hospital. The control subjects were 182 persons who did not have any gastrointestinal diseases, including the patients from the department of orthopedic surgery and healthy volunteers. The survey covering general characteristics, life style, dietary habits, eating behaviors, and food intake frequency was administered by individual interviews using questionnaires. The results of the study suggest that high BMI, daily life stress, pessimistic personality, lack of physical activities, and familial cancer history might be the possible risk factors for the incidence of colorectal cancer. Dietary factors suspected as risk factors for colorectal cancer in the present study included strong preferences to meats, salty and fatty taste foods, low intake of water, alcohol drinking, smoking, coffee intake and irregular eating habits. A high consumption of seaweeds, green-yellow vegetables, light-colored vegetables, and green tea was suggested as a preventive factor for colorectal cancer. It is recommended to conduct more extensive and systematic surveys in the near future to reconfirm the risk factors of colorectal cancer in consideration of the characteristic food culture in this community. The results of the present study may be applied to nutritional education for the prevention of colorectal cancer for the local residents. (Korean J Nutrition 38(2): 125～143, 2005)

The purpose of this study was to investigate the economic lives of single households with the age of 30 through less than 50. The economic life was examined in three aspects; income, assets, and consumption expenditures and patterns. One hundred sixty single households were surveyed, with questionnaires for 15days from April 1 to April 15 of 2002, and analyzed with descriptive statistics. The results were as follows: about 30.8% of total single households in the sample were in the income group of 1,500,000 thought less than 2,000,000 won. The size of income for the 30's was less than that for the 40's. Compared with male single households, female single households were more in both low and high levels of income. The saving rate tended more or less to be low. The more the age, the higher the saving rate. As for debt, the 40's single households, male single households, high school single households (compared to the 30's single households, female single households, university and graduate single households, respectively) were relatively higher. In general, the single households tended to have debts due to preparation for housing, credit over use. The assets tended to be managed by themselves. The economic preparation for the old life was done by banking system rather than insurance. The average monthly living costs was higher in the age of the 40's single than the age of the 30's single. The living costs of the female single households was higher or lower than those of the male single households. As for consumption patterns, there was the most in the expenditure allocation for food away from home, then for culture entertainmentㆍsocial life, and for clothing and shoes. As for the convenience of the consumption life in overall, there were more responses in moderation and inconvenience than in convenience.

This study considered the whole intake patterns and realities of consumption of instant noodles on sales targeting children and adolescents. Based on a total of 1021 subjects, data from self-administrated questionnaires were collected and analyzed using comparative statistical analysis, including frequency, chi-square, t-test, and one-way ANOVA. Results of the study were as follows. The preference levels for instant noodles by children and adolescents were 5.25, thereby showing a more than moderate preference. Middle school boy students' preference for instant noodles was the highest. The main reason for preferring instant noodles was taste and convenience. The main reason for disliking instant noodles was poor nutrition and likelihood of becoming fat. The intake of instant noodles was the highest between lunch and dinner with a frequency of once to twice per week. Content of soup powder given taking instant noodles was the largest in having putted all. The soup quantity of being left given taking instant noodles was possessed the majority in almost not eating soup. The main reason for not consuming soup was being full or concerns for health. A significant difference was observed in preference level for instant noodles and in intake patterns depending on the respondents' general characteristics. Limitations and future research directions are also discussed.

This study was conducted to examine the microbiological quality indicators (total bacterial count and coliform count) and physicochemical quality indicators (pH, redness, volatile basic nitrogen [VBN] content) of meat according to various storage temperatures (-20~15℃) and packaging methods (wrap, vacuum). Based on these results, we proposed a safe consumption period. Redness, pH, and VBN content were not considered appropriate for setting the expiration date, as the redness and pH of the meat after spoilage were better than the standard values for both vacuum and wrap packaging (p<0.05). Additionally, the VBN content at 2 and 4℃ increased slightly (fresh level) until the initial time of spoilage (1.0×10⁶ colony-forming unit [CFU]/cm²) and then increased rapidly thereafter. Therefore, the results were not consistent with microbial spoilage. When the decay point was evaluated based on the presence of microorganisms, vacuum packaging extended the storage period approximately 2.5-fold when compared with wrap packaging, and the meat could be stored at 2 or 4℃ for 40 or 23 days, respectively. Therefore, to evaluate meat quality, microbial indicators should be considered first. The microbiological standards proposed in this study can be used for safety management during the distribution of meat. However, to ensure meat safety, additional investigations of appropriate indicators of freshness must be conducted.

This study analyzed the health characteristics and comorbidity of adult men aged 40 years by dividing them into a control group of those without any disease related to fine dust and a patient group with one or more diseases related to fine dust in areas with high levels of fine dust pollution using the sixth and seventh Korea National Health and Nutrition Examination Survey (2013-2017). Among the general characteristics, the mean age of the patient group was significantly older than that of the control group (p<0.001), and in terms of the health-related characteristics, the frequency of breakfast consumption in the patient group was higher than in the control group (p<0.043). The body measurements were similar in the patient and control groups. Regarding the prevalence of comorbidity, the patient group showed a higher prevalence of hypertension, dyslipidemia, stroke, myocardial infarction, heart failure, and diabetes than the control group, but the differences were not statistically significant. On the other hand, the prevalence of other cancers (except stomach cancer, liver cancer, colorectal cancer, breast cancer, and cervical cancer) in the patient group was higher than in the control group (p<0.05). In terms of the clinical characteristics, the glycated hemoglobin levels in the patient group were significantly higher than in the control group (p<0.048). Information on nutrition and health in areas with frequent occurrences of fine dust was obtained through the study results, which can be used as basic data for measures of health and diet management against diseases that will increase in relation to fine dust.

Sodium chloride plays an important role as the main condiment at daily meal. It is well known that humans require sodium chloride as an essential nutrient to keep the homeostasis of electrolytes. The amounts of salt intake may be a reflection of geography, culture and food habit rather than necessity. Lee has reported (1962) that Koreans ingest high amounts of sodium chloride in their meals, with an intake of excess carbohydrate (80-90% of total Calories) and low protein in their diet. This includes large amounts of rice, Kimchi and other fermented soybean products common in the Korean diet. This investigation was designed to study the dietary relations of sodium chloride to other nutrients in the Korean diet. Twenty four albino male rats, weighing from 290-300g, were divided into four dietary groups according to the amounts of carbohydrate, protein and fat in the basal diet. Each diet contained a rice powder as a carbohydrate source. Diet I was a control diet, Diet II, low protein, Diet III, low protein and low fat diet and Diet IV, low fat diet. All rats were provided with 3% sodium chloride solution. Diet and salt solution were given ad libitum. The experiment was carried out for 9 weeks during which time the body weight, the food intake, and 3% sodium chloride solution consumption were determined. At the 9th week, the urine was collected the blood sample from the artery of each rat for the analysis of sodium and potassium and other chemical studies. The rats were sacrificed and the kidney, adrenal, liver and spleen were measured, and observed changes of the pathological tissue in the kidney and adrenal. The results were summarized as follows: 1) The growth rate was higher in Diet I than in the other experimental diets (II, III and IV) after 4 weeks. There was no significant difference found between the experimental Diets II, III and IV. 2) The daily food intake was greater in the experimental diets II, III and IV than in the control diet. However, there was no difference among the high carbohydrate diets Diet II, III and IV. 3) The daily water (3% sodium chloride solution) intake was also greater in the Diets II, III and IV, than in the control diet. However, there was no difference between Diets II, III and IV. 4) The concentration of sodium and potassium in the blood were within the normal range in all diets. 5) The amount of sodium chloride in the urine was significantly greater in Diets II, III and IV than in the control diet. Diets II, III, IV had a larger amount of sodium solution consumption. 6) Observation of pathological tissue in the experimental diets found a cell proliferation in the glomerlulus of the kidney, while such change was not found in the control diet.
