This study investigated the effects of a healthy image on the preference and intake frequency of meat and animal products. The study looked into beef, pork, chicken, sausage, mackerel, cutlass fish, croaker, tuna, squid, shrimp, clams, fish cakes, eggs, milk, yogurt, ice cream, and cheese. A total of 359 usable surveys given to elementary school students, college students, and adults were collected using a convenient sampling method. While milk had the healthiest image, sausage had the least healthy image. The respondents preferred yogurt the most and sausage the least. The intake frequency of eggs was the highest and clams the lowest. The healthy image, preference, and intake frequency for all studied foods showed significant differences across both gender and age. The relationship between healthy image and preference was significant for all foods, and a healthy image always had a positive influence on preference. The relationship of healthy image and intake frequency was significant in 14 foods except for mackerel, cutlass fish, and tuna. Also a healthy image created a positive effect on the intake frequency of 14 foods.

BACKGROUND/OBJECTIVES: The aim of this study was to investigate the perception of sugar reduction, nutrition education, and frequency of snacking in children according to the self-perceived dietary preferences for sweet taste by mothers in Busan. SUBJECTS/METHODS: A total of 277 mothers were surveyed, and their perceptions of sugar reduction and the frequency of snacking in children were assessed using a questionnaire. The subjects were classified into either a sweet (n = 91) or an unsweet (n = 186) group according to their self-perceived preferences for a sweet taste. RESULTS: In the sweet group, the results for sweet products were sweetened ice (86.8%), confectionery (74.7%), processed milk (73.6%), carbonated beverages (71.4%), and fermented milk (53.9%). In the unsweet group, the results were sweetened ice (88.7%), carbonated beverages (78.5%), processed milk (75.8%), confectionery (69.4%), and fermented milk (50.5%). The necessity of sugar intake reduction was high in both groups (sweet = 89.0%, unsweet = 82.8%). Beverage purchases after identifying the nutrition labeling was significantly lower in the sweet group than in the unsweet group (P < 0.05). The reasons for the beverage purchases instead of water were "habitually" (50.5%) and "like sweet taste" (25.3%) in the sweet group (P < 0.01). Snacking in children was significantly higher in the sweet group based on the increased frequencies of carbonated drinks (P < 0.01), fast food (P < 0.001), candy and chocolate (P < 0.05), crackers (P < 0.01), ramen (P < 0.01), and fish paste/hotdogs (P < 0.01). The frequency of purchase education after identifying the nutrition labeling was significantly lower in the sweet group than in the unsweet group (P < 0.01). CONCLUSIONS: These findings suggest that a perception of sugar reduction and practical nutrition education aimed at reducing the sugar intake are necessary to improve dietary habits.

Objectives: This study compared the nutritional status of child-bearing age women between the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea). Methods: The data presented in the DPRK Final Report of the National Nutrition Survey 2012 was utilized for the nutritional status and food intake of North Korean women. To produce the South Korean women's data comparable to those of North Korean women, the data from the 2012 National Health and Nutrition Survey were analyzed and the data presented in the 2010 Report of the Korean Agency for Technology and Standards were utilized. Results: The prevalence of maternal anemia (blood hemoglobin < 12.0 g/dL) was over 30% in all the age groups of North Korean women and 8.9%, 14.2%, 16.4% in 20-29, 30-39, 40-49 year old South Korean women, respectively. The prevalence of maternal protein-energy malnutrition (Mid-Upper Arm Circumference < 22.5 cm) was 25.2%, 21.4%, 21.8% in 20-29, 30-39, 40-49 year old North Korean women, respectively and less than 10% in all the age groups of South Korean women. Result of dietary diversity comparison showed that North Korean women consumed less food than South Korean women at all food groups: grains, fruits, vegetables, meat, and dairy. Percentage of North Korean women having consumed protein rich foods-meat and fish, eggs or dairy products-were much lower than those of South Korean women. Conclusions: The striking disparity of nutritional status between South and North Korean women indicates that nutrition support for North Korean women is essential in the process of preparation for a unified nation.

This study investigated the nutrition knowledge, dietary habits, and food intake frequency according to hospitalization after breast cancer surgery and experience of breast cancer among female adults residing in the Bucheon area. Subjects were 52 female breast cancer survivors 27 in the hospitalization group (HG) and 25 in the non-hospitalization group (non-HG)] and 52 controls. Data included the results of self-administered questionnaires, as well as anthropometric data and blood biochemical values of breast cancer survivors collected from electronic medical records. Statistical analysis was performed using SPSS 20.0 program. Nutrition knowledge and dietary habits revealed no significant differences between HG and non-HG, but intake frequency of root and tuber crops and kimchi was significantly higher in the HG group than the non-HG group (p<0.05). According to experience of breast cancer, total scores of nutrition knowledge among survivors (8.2) were significantly higher than those of the control group (6.3) (p<0.001). Fish and shellfish and fruit intake frequencies were significantly higher in the survivors group, whereas intake frequency of fast food, convenience food, and alcohol was significantly lower compared to the control group. Overall, these findings indicate it is necessary to develop and spread nutrition education guidelines to prevent the occurrence and recurrence of breast cancer.

The purpose of this study is to provide useful information which will aid in the promotion of nutritional policy in the Korean rural area which are derived from a survey of intake and source of protein in some Korean rural adults and the correlations between their protein nutrition and various nutrients, the uses of tobacco, alcohol, coffee, etc. The survey was conducted from July, 24 through July, 18, 1989. The healthy subjects were 45 males(average age 42.3, average BMI 22.1kg/m2) and 55 females (44 years, 21.2 kg/m2) residing in Sungjoo Kyun, Chulanam-Do, Korea. The subjects were examined for the anthropometric, food Intake and food habits. Their daily diets were measured by 24-hr recall method. The results can be summarized as follows : The daily mean protein intakes of male and female subjects were 9595 of RDA(66, 5g) (16. 7% of total food intake per day) and 102.3Bh of RDA(61g) (14.8% of total intake per day) respectively. The order of sources of animal protein in all subjects was fish(47.9%), meat(29.8%), milk (12%), and egg(10.3%). Among protein sources the intake frequencies of fork and chicken were higher than those of others. The protein nutrition of the subjects showed positive correlations with energy and fat, carbohydrate, fiber at the level of significance of 1%. The protein nutrition of the male subjects showed no correlation with age, BMI, uses of alcohol, coffee, medicine, but the plant protein nutrition showed a positive correlation with smoking and exercise(at 5%). And the protein nutrition of the male subjects showed no correlations with uses of tobacco, alcohol, coffee, medicine and their opinion of their present state of their health, but the age of the male subjects showed negative correlations with milk(at 1%) and egg(at 5%). In conclusion, the daily protein Intake was good and the main sources of animal protein were fishes in rural adults. The protein nutrition of the subjects showed a correlation with energy, fat, carbohydrate and in the case of female, milk and egg intakes showed the negative correlation with age.

This study was conducted to find the differences in food consumption frequency of the middle aged(male 20, female 50) and the elderly(male 15, female 15) living in Chonju in December, 1998 according to food habits, smoking, alcohol drinking and exercising habit, health status, and the levels of nutrition knowledge and attitude store. The foods frequently consumed among the subjects were kimchi(15.4/week), mixed rice(11.5/week), rice(7.6/week), vegetables in soup, jjigae and jorim(5.0/week), mandarins and oranges(5.e/week), and seasoned laver(4.3/week). There were several factors influencing food consumption patterns. These were age, regularity of meal times, the status of smoking, alcohol drinking and exercising, and the level of nutrition attitude. The elderly ate cooked rice more frequently, while the middle aged ate fish, especially blue fishes more frequently. The middle aged who had breakfast regularly ate milk and milk products, legumes and fruits frequently. Those who smoked seemed to eat less cereals and starches and fats, while those who didn't smoke ate more sugars. The alcohol drinking group also ate less fats and the exorcising group ate almost all of food groups frequently. The status of health showed to be related with food consumption patterns. The normal group in hemoglobin ate eggs more frequently than the anemia group and the high risk group in blood pressure ate almost all of food groups more frequently. The high level group for nutrition attitude score chose vegetables, fruits, and milk and milk products more frequently than the other groups. On the other hand, low level group for nutrition attitude score was apt to eat ramyun, ham-sausage, and carbonated beverages more frequently. Therefore, nutrition education to improve the food habits find to change nutrition attitude is necessary to promote health status anti mole attention should be taken to the high risk group in blood pressure to guide proper food and nutrition intakes.

BACKGROUND/OBJECTIVES: Vitamin E is essential for health, and although vitamin E deficiency seems rare in humans, studies on estimates of dietary intake are lacking. This study aimed to estimate dietary vitamin E intake, evaluate dietary adequacy of vitamin E, and detail major food sources of vitamin E in the Korean population. SUBJECTS/METHODS: This study used data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2016-2019. Individuals aged ≥ 1 year that participated in a nutrition survey (n = 28,418) were included. Dietary intake was assessed by 24-h recall and individual dietary vitamin E intake was estimated using a newly established vitamin E database. Dietary adequacy was evaluated by comparing dietary intake with adequate intake (AI) as defined by Korean Dietary Reference Intakes 2020. RESULTS: For all study subjects, mean daily total vitamin E intake was 7.00 mg α-tocopherol equivalents, which was 61.6% of AI. The proportion of individuals that consumed vitamin E at above the AI was 12.9%. Inadequate intake was observed more in females, older individuals, rural residents, and those with a low income. Mean daily intakes of tocopherol (α-, β-, γ-, and δ-forms) and tocotrienol were 6.02, 0.30, 6.19, 1.63, and 1.61 mg, respectively. The major food groups that contributed to total dietary vitamin E intake were grains (22.3%), seasonings (17.0%), vegetables (15.3%), and fish, and shellfish (7.4%). The top 5 individual food items that contributed to total vitamin E intake were baechu kimchi, red pepper powder, eggs, soybean oil, and rice. CONCLUSIONS: This study shows that mean dietary vitamin E intake by Koreans did not meet the reference adequate intake value. To better understand the status of vitamin E intake, further research is needed that considers intake from dietary supplements.

This study investigated the effects of the number of washes and alkaline treatments ($NaHCO_3$ concentrations) and the concentration of potato starch on the quality of fish meat paste products prepared from sand lance Ammodytes personatus Girard. We found significantly (P<0.05) higher ratings for the all textural parameters (hardness, brittleness, elasticity, and cohesiveness) of the sand-lance meat paste products (SLMPPs) that were washed three times with a 0.5% $NaHCO_3$ concentration. We determined that an 8% concentration of potato starch leads to the best textural properties in SLMPPs. As the amount of potato starch was increased, the redness values of SLMPPs decreased significantly (P<0.05), but the differences in the sensory evaluation parameters (texture, flavor, taste, and overall acceptability) between the SLMPPs were not significant.

Aquaculture production of Hounder has been increased in the last decade in Korea. However, moist pellet primarily made of raw fish has been used as feed for flounder. Therefore, for further expansion of flounder farming, it is essential to employ practical formulated feeds which can support reasonable growth. Several studies on nutrition (Lee et al., 2000) and utilization of some plant protein source as a substitute for fish meal (Kikuchi, 1999) have been conducted for flounder diets. (omitted)

Peroxidative stimuli mediated by high polyunsaturated fatty acid administration in rats induced in vivo lipid peroxidation and resulted in increased urinary excretion of a number of lipophilic aldehydes and related carbonyl compounds. These secondary lipid peroxiation products, measured as 2, 4-dinitrophenylhydrazine deritives, were detected and identified by the newly developed HPLC method. The identified urinary lipophilic nonpolar aldehydes and related carbonyl compounds were butanal, butan-2-one, pentan-2-one, hexanal, hex-2-enal, hepta-2, 4-dienal, hept-2-enal, octanal, and oct-2-enal. Lipophilic polar aldehydes such as 4-hydroxyhex-2-enal and 4-hydroxyoct-2-enal were also identified. A polyunsaturated fatty acid diet containing n-3 fatty acids generally caused high levels of urinary excretion of lipophilic aldehydes and related carbonyl compounds in rats than a normal diet. Significantly increased secondary lipid peroxidation products were hexanal, hepta-2, 4-dienal, octanal, 4-hydroxyhex-2-exal, 4-hydroxyoct-2-enal, and a number of unidentified compunds.
