The purpose of this study was to compare the awareness of dietary patterns and health of full-time and employed housewives. The investigation gathered information on general characteristics, dietary lifestyle, nutritional status, and health by questionnaire as well as anthropometric measurements. The subjects included housewives living in Seoul and Gyeonggi Province (86 full-time and 127 working housewives) during November 2009 to January 2010. The average age, height, and weight of the housewives were $45.8{\pm}7.6\;yr$, $161.0{\pm}8.4\;cm$, and $55.7{\pm}6.3\;kg$, respectively. The average monthly income of the households was 3 million to 5 million won (31.4% full-time and 37.0% working housewives), and their average food expense was 200,000 to 500,000 won (46.5% full-time and 48.1% working housewives). More than 90% of the studied homes were nuclear families and the most common number of children was 2 to 3 (79.1% full-time and 76.4% working housewives). The ratio of employed housewives who ate regular meals was 35.4%, but that of the full-time housewives was 48.2% (p<0.05). Of the working housewives, 7.1% never ate breakfast and the primary reason for skipping breakfast was 'busy in the morning' (61.1%). The type of food that the housewives preferred when eating out was Korean food, both for the full-time and employed housewives (76.0%). All the housewives overate calories and the full-time housewives ate more protein, fat, vitamin A, vitamin B1, vitamin B6, niacin, vitamin C, vitamin E, folic acid, and cholesterol than the employed housewives (p<0.05). Both the full-time and employed housewives were more satisfied with supper than with other meals. About 30.6% of the full-time and 33.9% of the working housewives had no interest in health, but answered that regular exercise was very important for health (33.3% full-time and 39.7% working housewives). In conclusion, working housewives have poor dietary habits and nutrient intakes, thus substantial measures to improve these problems are urgently needed.

This study was conducted to identify the major dietary patterns of Korean adult men and to examine the relationship between subjective stress perception and these dietary patterns using data from the 2014~2016 Korean National Health and Nutrition Examination Survey (KNHANES). Of the 23,080 total subjects, adult men between the ages of 19 and 64 who did not take the questionnaire or answer the questions relating to depression, and cases where the daily energy intake was less than 500 kcal or more than 5,000 kcal in the Food Frequency Questionnaire were excluded. This left a total of 3,464 subjects who were included in the final analysis. We performed a factor analysis based on the yearly mean intake frequency of 41 food groups to identify the major dietary patterns. Three major dietary patterns were identified (factor loading >0.3), including the 'Healthy pattern', 'Processed meat pattern', and the 'Alcohol pattern'. The 'Healthy pattern' was characterized by higher intake of beans, tofu, vegetable, fish, and fruits. The 'Processed meat pattern' was characterized by high consumption of processed meats and instant foods. The 'Alcohol pattern' was characterized by a higher intake of alcohol. As a response to the subject's subjective perception of stress, the most answered 'a little' according to age, marital status, occupation, income, residential area, smoking status, drinking status, and exercise status. People whose diets followed the 'Processed meat' and 'Alcohol' patterns had significantly higher scores on subjective stress perception compared to people following the 'Healthy pattern'. To manage subjective stress, it is more effective to maintain health by relieving stress through a healthy method that combines healthy eating and exercise rather than following an unhealthy diet as characterized by the 'processed meat' and 'alcohol' dietary patterns.

This study was conducted in order to investigate the antioxidant and antimicrobial activity of Solanum nigrum L. fruit powder after undergoing different extraction solvent processes. The total phenolic content of Solanum nigrum L. fruit powder measured a 14.66 GAE mg/g after undergoing ethanol extraction, and the total flavonoid content measured at 201.23 mg CE/g when undergoing ethanol extraction. The ABTS radical scavenging activity was 160.38~209.53 TEAC umol/g, and the DPPH radical scavenging activity was 53.99~90.76 TEAC umol/g, which indicated a higher level of antioxidant power in the ethanol extract as opposed to in the water extract. The FRAP (ferric reducing antioxidant power) of Solanum nigrum L. fruit powder was 115.58~194.58 TEAC umol/g, and B. subtilis KCTC 2189 showed greater antimicrobial activity in the ethanol extract (concentration 200 ug/uL) as opposed to the water extract. Solanum nigrum L. fruit powder revealed differences in antioxidant and antimicrobial activity between the different extraction solvents. In particular, ethanol extract had higher antioxidant and antibacterial activity, meaning it is more favorable for usage as a functional food material.

This study evaluated the nutrient intake with increasing coffee consumption for 403 adults aged over 30 years in Korea. The 403 subjects were national health screening examinees, who visited Sahmyook Seoul Hospital's Comprehensive Check-up Center between 2017.11.01 and 2018.12.18. The subjects were asked to answer questionnaires covering a 24-hour recall fluid and dietary intake before the health examination. The research ethics council of Sahmyook University (2-7001793-AB-N-012019036HR) approved this study. Coffee consumption exceeding two servings daily was more likely in males, in those aged between 30 and 40 years, and in the smoking, drinking, non-exercise, non-breakfast groups compared to each counterpart. The correlation between the coffee consumption frequency and current nutrient density showed negative correlations in most micronutrients. The mean nutrient density decreased gradually with increasing coffee consumption (<1 serving daily, ${\leq}1{\sim}2$ servings daily, >2 servings daily) in the ANOVA analysis. Therefore, the progressive adverse health effects of excessive coffee consumption needs to be researched further, and a daily total caffeine limit should be suggested in education of the nation levels.

This study was conducted to investigate the effect of the differences in nutrient intakes on the onset of eye disease in the ophthalmic disease group vs. the normal group. The analysis method of this study was performed by adjusting age and gender. The daily caloric intake was 1,672.1±26.4 kcal in the ophthalmic disease group which was significantly lower than the 2,041.5±13.6 kcal intake in the normal group (P=0.006). The intake of proteins (P=0.015) and carbohydrates (P=0.000) was significantly lower in the ophthalmic disease group than in the normal group. The incidence of eye diseases was found to decrease by about 0.79 (95% CI: 0.74~0.83) times as the NAR index of protein was increased, followed by 0.79 (95% CI: 0.64~0.98) times with an increase in niacin consumption. In this study, income, BMI, smoking, alcohol consumption, and quality of life were considered as the confounding variables related to eye disease, along with age and gender, but did not lead to show significant results. It was found that the ophthalmic disease group had an unbalanced nutritional intake compared to the normal group. Therefore, we conclude that nutrition education is necessary to ensurebalanced eating habits for management and prevention of degeneration after the onset of eye diseases.

This study evaluated the correlation between serum uric acid level and the nutrients adequacy ratio (NAR) using data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2016~2019. This is a cross-sectional study in which 6,579 Korean male adults were divided into quartiles according to their uric acid levels. All analyses were performed with adjusted age. Uric acid decreased as the age increased from the age group 19~29 years to 30~49 years and then to 50~64 years. Interquartile results of serum uric acid levels showed that increases in the serum uric acid levels were associated with decreases in LDL-cholesterol (P<0.01), triglycerides (P<0.001), body weight (P<0.001), waist circumference (P<0.001), body mass index (P<0.001), systolic blood pressure (SBP) (P<0.001), diastolic blood pressure (DBP) (P<0.001). However, uric acid levels decreased with an increase in HDL cholesterol (P<0.001). The analysis of the NARs according to the quartiles of serum uric acid levels in men showed that an increase in serum uric acid levels was associated with a decrease in the NAR levels of dietary fiber (P<0.001), calcium (P<0.001), and folic acid (P<0.001).

The development of soy cutlets containing textured soy protein (TSP) as a meat analog was studied. In order to decrease the beany flavor and to increase the texture, TSP was treated with 0.3% Flavourzyme or 0.1% Protamex for 10 or 20 min, respectively. The degree of hydrolysis for TSP treated with Protamex was higher than that treated with Flavourzyme. Hydrolysis was observed to increase as the reaction time was increased for both Flavourzyme and Protamex. The water holding capacity of TSP treated with Protamex for 10 min was the highest, and that treated with Flavourzyme for 20 min was similar to that of Protamex treatment for 20 min. The oil binding capacity of TSP treated with Protamex for 20 min was the highest. The hardness of the soy cutlets using TSP treated with Flavourzyme for 10 min was higher than that treated for 20 min, while that of Protamex treated for 20 min was higher than that treated for 10 min. The cohesiveness of the soy cutlets using TSP treated with Flavourzyme or Protamex for 10 min was higher than those treated for 20 min. The chewiness of the soy cutlets treated with Flavourzyme for 10 min was higher than for those treated for 20 min, while those treated with Protamex for 20 min was higher than those treated for 10 min. The springiness of TSP treated with Flavourzyme for 20 min was higher than those treated for 10 min, and higher than those treated with Protamex for 10 or 20 min. For sensory evaluation, the beany flavor of the soy cutlets treated with Protamex for 20 min was the weakest. The flavor and chewiness of both a pork cutlet and a soy cutlet treated with Protamex for 20 min were the best. In the overall quality, soy cutlets treated with Protamex for 20 min was the most desirable. In conclusion, soy cutlets treated with 0.1% Protamex for 20 min could be a reasonable substitute of pork cutlets.
