The purpose of this study was to analyze consumption patterns of health functional foods (HFF) according to climacteric symptoms. Subjects were 450 middle-aged women divided into four groups by Kupperman's index. This study collected all information by self-administrated questionnaires. Higher Kupperman's index was associated with higher Menopause-specific quality of life questionnaire (MENQOL) (P<0.001) and current smoker ratio (P<0.01) as well as lower monthly income (P<0.05). Exactly 28.4% of subjects showed negative responses to effectiveness of HFF. The average number of HFF intake per person was 2.01. The main reason for consumption of HFF was treatment or prevention of disease (33.6%). The information source for buying HFF was family or relatives (40.0%). The main types of HFF were vitamins (28.2%), omega-3 fatty acid (18.6%) and red ginseng (17.3%). The intake ratio of individual approval type (Cynanchum extract and Angeli extract) was significantly higher in subjects with high Kupperman's index (P<0.001). In conclusion, these results can be used as basic data that reflect middle-aged women's needs for HFF intake according to climacteric symptoms.

Background: Green tea extracts are approved as nonprescription drug and available as health functional foods, health foods, and beverages. Clinical information on the products is lacking. Methods: Information about the products on green tea nonprescription drugs was obtained from the website of the Korea Pharmaceutical Information Center. The Naver, i.e., a top ranking online search portal, was used for compiling the list of the health functional food products using key words of 'green tea catechin' on August 23, 2018. The recommended daily dosages of catechins were calculated as 30% of the total dried mass of green tea and about 50% of the catechins were considered as epigallocatechin gallate (EGCG). Results: A total of two types of nonprescription drugs containing green tea powder or extracts, nine health functional food products, and three types of health foods were found. The regulatory requirements of the EGCG exceeding 800 mg were reported to be associated with adverse effects of elevated liver enzyme. If consumers take several green tea products concurrently, such as nonprescription drugs with health functional foods or health foods, it could exceed the recommended amount of EGCG. Conclusion: The concurrent use of green tea products as nonprescription drugs, health functional foods, and healthy foods may lead to an increased exposure to EGCG. Pharmacists should be aware the availability of various types of green tea products and the potential risk of liver toxicity due to excessive consumption of EGCG.

[Purpose] Functional foods are thought to strongly influence the structure and function of the brain. Previous studies have reported that brain-boosting diets may enhance neuroprotective functions. Certain foods are particularly rich in nutrients like phytochemicals that are known to support brain plasticity; such foods are commonly referred to as brain foods. [Methods] In this review, we briefly explore the scientific evidence supporting the neuroprotective activity of a number of phytochemicals with a focus on phenols and polyunsaturated fatty acids such as flavonoid, olive oil, and omega-3 fatty acid. [Results] The aim of this study was to systematically examine the primary issues related to phytochemicals in the brain. These include (a) the brain-gut-microbiome axis; (b) the effects of phytochemicals on gut microbiome and their potential role in brain plasticity; (c) the role of polyunsaturated fatty acids in brain health; and (d) the effects of nutrition and exercise on brain function. [Conclusion] This review provides evidence supporting the view that phytochemicals from medicinal plants play a vital role in maintaining brain plasticity by influencing the brain-gut-microbiome axis. The consumption of brain foods may have neuroprotective effects, thus protecting against neurodegenerative disorders and promoting brain health.

In this research, we examined the shifts in determinants influencing the frequency of eco-friendly food purchases pre- and post-COVID-19. Our analysis utilized filtered 2019-2021 Consumption Behavior Survey data from the Korea Rural Economic Institute Food, excluding any irrational responses. Given the nature of the dependent variable, a multinomial logistic regression model was employed with demographic factors, variables pertaining to food consumption behavior, and variables concerning food consumption awareness as predictors. Following the onset of the COVID-19 pandemic, an individual's level of education was observed to positively influence the frequency of eco-friendly food purchases. In contrast, income level and fluctuations in food consumption expenditure did not appear to have a discernible impact on the purchasing frequency of such eco-friendly products. Irrespective of the advent of COVID-19, variables such as the frequency of online food purchases, the utilization of early morning delivery services, dining out frequency, and the intake of health-functional foods consistently demonstrated a positive correlation with the propensity to purchase eco-friendly foods. Overall, consumers prioritizing safety, quality, and nutrition over price, taste, and convenience in their procurement decisions for rice, vegetables, meat, and processed foods exhibit an increased inclination toward the acquisition of eco-friendly food products.

The purpose of this study was to estimate the consumption prevalence of vitamin and mineral supplements as health functional foods (VM-HFF) and to examine the factors associated with VM-HFF consumption behaviors in adolescents. A total of 1,407 adolescents attending middle or high schools from various cities and rural communities in Korea participated in this study. The prevalence of VM-HFF consumption was 41.7%, with boys showing a higher consumption than girls (p<0.01). VM-HFF consumption was higher in families with higher socioeconomic status and for families with parents that exhibited higher concerns about their child's health, growth, and nutritional intake (p<0.001). Most consumers of VM-HFF consumed HFFs 'when healthy' (50.1%), and acquired nutritional information from 'their families & relatives' (50.9%). Most consumers responded that VM-HFF was 'a little effective' (54.3%), followed by 'no obvious effects' (37.1%), and 'very effective' (7.4%). The effectiveness of consuming VM-HFF was mainly for 'fatigue recovery' (39.0%) and 'health improvement' (28.2%). Most consumers purchased HFFs at 'pharmacies & oriental medicine clinics' (53.8%) and at 'health functional food stores' (18.8%). Most consumers 'occasionally' (51.1%) or 'seldom' (27.3%) checked nutrition facts when purchasing, with 58.9% of consumers understanding the nutritional label for 'the most part', but only 8.7% of them understanding it 'very well'. Among the VM-HFF, consumers preferred calcium- and vitamin C-supplements. Consumers' mini-dietary assessment scores were higher than those of non-consumers. The results above showed that VM-HFF consumption was widely spread among adolescents, but few consumers checked and understood the nutrition label when they purchased VM-HFF, and were highly dependent on the advice and information from non-professional nutritionists, such as families & relatives. Therefore, it is necessary to educate adolescents to help them read nutrition labels and select the proper VM-HFF.

Sangju, a city in the North Gyeongsang Province, is well known as "Three Whites", representing its three main agricultural products: rice, silkworm, and dried persimmons. Therefore, development of a variety of dishes or products that can promote the consumption of dried persimmons is an urgent requirement for this region. This study was designed to provide fundamental information for revitalizing community-based specialized agriculture through scientific inquiry into medicinal foods and to develop a medicinal food menu based on the results of previous research and pre-survey. The pre-survey results and incompatibility revealed that palatability influenced people's decision to consume dried persimmons far more than pharmacological functionality. Therefore, palatability played an important part in the development of dried persimmon puddings with acceptable texture. These dishes are in high demand as they suit the tastes of variety of consumers. The inclusion of various additives lowered the sugar content in the developed foods and made the products alkalescent (pH > 7), thereby improving functionality. Unique color and flavor additives were also important criteria that determined the selection attributes of the developed medicinal foods. In addition, the additives had a positive effect on the fragrance and texture of the foods. In conclusion, the results suggested that use of additives provides significant advantages in promoting the consumption of Sangju-dried persimmons by improving both functionality and palatability.
