Dietary supplements have exhibited myriads of positive health effects on human health conditions and with the advent of new technological advances, including in the fields of proteomics, genomics, and metabolomics, biological and pharmacological activities of dietary supplements are being evaluated for their ameliorative effects in human ailments. Recent interests in understanding and discovering the molecular targets of phytochemical-gene-protein-metabolite dynamics resulted in discovery of a few protein signature candidates that could potentially be used to assess the effects of dietary supplements on human health. Persimmon (Diospyros kaki) is a folk medicine, commonly used as dietary supplement in China, Japan, and South Korea, owing to its different beneficial health effects including anti-diabetic implications. However, neither mechanism of action nor molecular biomarkers have been discovered that could either validate or be used to evaluate effects of persimmon on human health. In present study, Mass Spectrometry (MS)-based proteomic studies were accomplished to discover proteomic molecular signatures that could be used to understand therapeutic potentials of persimmon leaf extract (PLE) in diabetes amelioration. Saliva, serum, and urine samples were analyzed and we propose that salivary proteins can be used for evaluating treatment effectiveness and in improving patient compliance. The present discovery proteomics study demonstrates that salivary proteomic profile changes were found as a result of PLE treatment in prediabetic subjects that could specifically be used as potential protein signature candidates.

This study was carried out to examine the relationship between various characteristics of Korean traditional dishes such as preference, function, occurrence and preparation, with children and adolescents' characteristics such as general characteristics and health status and health attitudes. Elementary school students had desirable health attitudes as measured using the subjectively perceived level of health status and purpose of meals. There were significant relationships between some characteristics and health concerned behaviors, which included the extent of eating healthy diets, the intake of nutritional supplements and the application of nutritional knowledge. We found out that there were significant positive correlations among four characteristics of traditional dishes and the preference for those dishes was more positively correlated with occurrence and preparation than with function. The effects of the subjects' characteristics on preference for traditional dishes differed in various ways.

Objectives: This study investigated the association between eating habits and the utilization of dietary supplements (DSs) according to food-related lifestyle (FRL) among Korean adults. Methods: This study included a total of 300 participants (150 men and 150 women) in their 20s to 60s living in Seoul and Gyeonggi Province. We identified two groups by factor and cluster analysis: an 'active pursuit' group and a 'passive pursuit' group. Differences in eating habits and DS utilization between the two groups were analyzed by chi-square test and t-test. Logistic regression analysis was used to analyze the effect of variables on DS consumption according to FRL. Results: There were significant differences between the two groups in terms of age, alcohol drinking frequency, total dietary score, change in DS consumption after coronavirus disease 2019, and current DS consumption (P < 0.05). The proportion who perceived many health benefits of DSs was higher in the 'active pursuit' group than in the 'passive pursuit' group (P = 0.003). The most commonly consumed type of DSs was multivitamins & minerals for the 'active pursuit' group, and omega-3 fatty acids for the 'passive pursuit' group. The 'an active pursuit' group consumed DSs 2.93 times more (95% confidence interval [CI]: 1.44-5.97) compared to the 'passive pursuit' group, after adjusting for confounders. In the 'active pursuit' group, the health pursuit (odds ratio [OR] = 6.54, 95% CI: 1.44-29.61) and rational consumption pursuit factors (OR = 0.26, 95% CI: 0.08-0.83) were associated with DS consumption, whereas only the health pursuit factor had a significant association (OR = 5.37, 95% CI: 2.08-13.88) within the 'passive pursuit' group. However, total dietary score and DSs consumption did not show a relationship. Conclusions: By understanding the consumption characteristics of DSs according to FRL, this can serve as basic data necessary for promoting health through the utilization of DSs and healthy behaviors.

In a rapidly changing society, the rise in standard of living and level of education has brought about a Qualitative change in consumption, especially food consumption. Accordingly, consumers' interest in and the consumption of health foods has also grown at a rapid pace, expanding the health food market. However. because of the consumer's lack of understanding and knowledge about health foods, the reality is a difficulty in establishing sound consumption. Accordingly, this study was conducted to analyze the consumers' purchase behavior for health food. Through this study, consumers will be able to rationally plan for the use of health food items and further to provide necessary information for planning and executing effective marketing strategies producers and distributors of health foods items. The subjects of this study are the 473 Seoul residents over the age of 20 who have used health food items in the past year. The result of this study showed the use of fatigue rehabilitators, with 93.2% of the respondents saying they have used it. was the highest. with natural products honey, vitamin supplements. restorative foods, mineral supplements, young-gi fellowing in order. Recovery from fatigue. with 3.81, was the top reason the respondents started using health food items, followed by maintenance of health, supplement nutrition. and prevent disease. Family and relatives topped the list of information sources with 3.76. followed by TV and friends. On the other the Internet(2.32) and radio(2.35) were shown to be the lowest information sources. Those surveyed listed quality(4.00), safety(3.99). and nutrition(3.93) as evaluative criteria for health food items, in order of importance. The place of purchase most frequented by consumers in the survey were specialty stores(35.3%) leading the way with department stores and door-to-door sales, pharmacy following behind. On the other hand. purchases from direct mail were the lowest with 1.5% The people who bought health food Items were shown to be parent/siblings(37.2%) , self(33.6%) followed by spouse(23.7%) Purchases made by children were very low with only 4.9%. Finally, the level of satisfaction after using health food products were generally not very high. Consumers seem to be satisfied with the effectiveness(3.37) and safety (3.15) of the products. which is very minute, and they were slightly dissatisfied with the quality of the products.

Many Koreans have been interested in health functional foods(HHFs). Use of health functional foods is growing rapidly. This study aims to identify the determinants of HFFs use focusing on health related factors. The subjects were 24,626 samples from Korea Health Panel in 2008. The subjects were divided into two group: under the 20 years old and 20 old and over. The logistic regression model was used to examine influence of health-related factors on use of HFFs for each group. About thirty percent of the subjects have used HFFs. The larger family size, higher education level of parents, more stable economic status and chronic diseases were positively related to use more HFFs in younger 20 years old. Higher education level, more stable economic status, chronic diseases were more likely to use HFFs in 20 years of age and over. Health related factors such as disability, chronic diseases, admission, and physician visit affect the use of HFFs in both groups. We confirmed that health related factors as well as socio-demographic and economic factors affect use of HFFs. In-depth knowledge about relationship between health related factors and HFFs is required.

This study was conducted to investigate housewives' perception, interest and consumption of health drinks made in a health food stores, and to assess the relationsh- ip between nutritionally-related-variables and the consumption of health drinks. Data was collected from 518 housewives in Chonnam province. Among many items which housewives perceived about health drinks, three factors of 'preference·health-care', ' quality·convenience' and 'price' were found to be represented. Housewives' perception of 'preference·health-care' was negatively correlated with nutritional knowledge. However, a positive correlation between the 'quality·convenience' and eating habits was found. Consumption of health drinks was positively correlated with the diet management score, the perception and interest in health drinks. However, the inverse relationship between consumption of health drinks and nutritional knowledge was observed. Multiple regression analysis showed that the interest and factors of perception of health drinks. Consumption of health drinks was not based upon accurate knowledge concerning nutrition, but was based upon the consumers' perception of taste preference and healthful quality. Therefore, there is a need to educate consumers about the nutritional value of health drinks and how to use nutritional supplements.

Purpose: This study identified words closely associated with the keyword "dietary supplement" (DS) using big data in Korean social media and investigated consumer perceptions and trends related to DSs before (2019) and after the coronavirus disease 2019 (COVID-19) pandemic (2021). Methods: A total of 37,313 keywords were found for the 2019 period, and 35,336 keywords were found for the 2021 period using blogs and cafes on Daum and Naver. Results were derived by text mining, semantic networking, network visualization analysis, and sentiment analysis. Results: The DS-related keywords that frequently appeared before and after COVID-19 were "recommend", "vitamin", "health", "children", "multiple", and "lactobacillus". "Calcium", "lutein", "skin", and "immunity" also had high frequency-inverse document frequency (TF-IDF) values. These keywords imply a keen interest in DSs among Korean consumers. Big data results also reflected social phenomena related to DSs; for example, "baby" and "pregnant woman" had lower TD-IDF values after the pandemic, suggesting lower marriage and birth rates but higher values for "joint", indicating reduced physical activity. A network centered on vitamins and health care was produced by semantic network analysis in 2019. In 2021, values were highest for deficiency and need, indicating that individuals were searching for DSs after the COVID-19 pandemic due to a lack an awareness of the need for adequate nutrient intake. Before the pandemic, DSs and vitamins were associated with healthcare and life cycle-related topics, such as pregnancy, but after the COVID-19 pandemic, consumer interests changed to disease prevention and treatment. Conclusion: This study provides meaningful clues regarding consumer perceptions and trends related to DSs before and after the COVID-19 pandemic and fundamental data on the effect of the pandemic on consumer interest in dietary supplements.

The underlying physiology of algal antioxidant compounds is reviewed in the context of seaweed biology and utilization. The application of seaweed antioxidants in foods, food supplements, nutraceuticals and medicine is considered from the perspective of benefits to human health. We advocate that direct consumption of seaweed products for their antioxidant composition alone provides a useful alternative to non-natural substances, while simultaneously providing worthwhile nutritional benefits. Economic utilization of seaweeds for their antioxidant properties remains in its infancy. This review provides examples ranging from laboratory studies through to clinical trials where antioxidants derived from seaweeds may provide major health benefits that warrant subsequent investigative studies and possible utilization.
