BackgroundThe widespread availability of health information online, coupled with the ease of access to the internet, has led pregnant women to rely heavily on online sources for pregnancy-related guidance. The internet-based information regarding nutrition enabled positive dietary changes for pregnant women. Although there are some important sources for pregnant women to collect their health information, some information increases maternal anxiety and difficulties based on a lack of information. Moreover, some women become confused due to conflicts on the same topics from different websites. However, concerns about the reliability and impact of this information have surfaced, contributing to heightened anxiety among expectant mothers. The importance of the quality of web-based information is increasingly recognized; however, no studies have evaluated the quality of nutrition-related information for pregnant women.ObjectiveThis study aims to bridge this research gap by assessing the quality of online health information concerning prenatal nutrition tailored to pregnant women.MethodsThis cross-sectional descriptive study was conducted through a Google keyword search on February 14, 2023. We used search terms, such as “pregnancy,” “pregnant women,” “diet,” and “nutrition” and conducted an exhaustive search on Google. Using the Quality Evaluation Scoring Tool (QUEST), we meticulously evaluated the quality of the retrieved information.ResultsThe top 20 Google-searched sites were evaluated using the QUEST tool. The average score was 11.7 points, ranging from 6 to 15, with most sites scoring between 11 and 15. Half of the websites lacked clear authorship and most gave weak or no attribution to specific scientific sources. While conflict of interest scored highest overall, with 60% showing no bias, some sites promoted products or specific interventions. Currency was inconsistent—only half were updated within 5 years. Complementarity received the lowest scores, with 70% lacking support for patient-physician relationships. The tone was generally positive, with 95% supporting their claims, though only one site used a balanced, well-reasoned tone. Discrepancies in cited guidelines on nutritional intake and inappropriate expressions about alcohol, weight management, and miscarriage raised concerns about the information’s accuracy and appropriateness.ConclusionsAlthough many websites use cautious language to mitigate commercial influence, deficiencies persist in crucial areas for empowering informed decision-making among pregnant women. From our assessment of the results, it was found that incorrect evidence information is provided at the top of search results, which is easily accessible to users. The inadequacies in attributing authorship, clarifying conflicts of interest, and ensuring the currency of information pose substantial challenges to the reliability and usefulness of online health resources in prenatal nutrition. Since internet-based information is the most accessible, reliable evidence should be provided to protect everyone from misinformation, including shallow health literacy demographics, and from potential physical and psychological harm.

ABSTRACTChicory (Cichorium intybus L.; witloof) contains bioactive compounds such as sesquiterpene lactones (SLs) and inulin, providing potential health benefits. However, the effects of cooking and processing on chicory's nutritional composition remain underexplored, particularly regarding its metabolite profile during low‐temperature processing. We aimed to investigate how different heating temperatures and processing times affect the nutritional composition of the whole chicory plants. We employed a targeted metabolomics approach to analyze the impact of low (30°C, 60°C) and high (100°C, microwave)‐temperature processing on chicory's nutritional profile, focusing on amino acids, sugars, organic acids, fatty acids, and other metabolites in both leaves and roots. Lower temperatures (≤ 60°C) influenced the concentration of nutritional components (sugars, free amino acids, organic acids), branched‐chain amino acids (which improve exercise performance), and γ‐aminobutyric acid (which has antihypertensive effects), depending on the composition of raw chicory. In contrast, high temperatures (100°C) and microwave processing, especially in chicory leaves, induced the formation of low molecular weight sugars from polysaccharides and glycosides, reduced free amino acid concentrations, and triggered heat‐induced aminocarbonyl reactions. This study provides valuable information for improving the flavor profile and potential health benefits of chicory by identifying optimal heat processing parameters to maintain desirable nutritional value.

Background/Objective: Frailty is a growing public health challenge in Japan's rapidly aging population, where 28.8% are aged ≥ 65. While multicomponent interventions have shown potential in preventing frailty, traditional face-to-face programs face accessibility challenges. This study evaluated the feasibility and short-term changes of an online multicomponent intervention on frailty-related factors among community-dwelling older adults. Methods: In this single-arm feasibility study, 132 participants (mean age 75.7; standard deviation 4.8 years, 65.2% women) completed a six-week online intervention combining exercise, nutrition education, cognitive activities, and the Coimagination Method to foster social connections, meeting weekly for 75 min sessions in groups of up to 10 participants. Results: The intervention demonstrated feasibility with a 96.4% retention rate and a 94.0% average participation rate. While no significant changes were observed in physical activity levels, autonomic nervous system indicators, or cognitive function, carotenoid scores and hemoglobin concentration improved significantly, with more pronounced improvements among women than men. Conclusions: This study demonstrates the high feasibility of online multicomponent interventions for older adults and suggests potential benefits for nutritional status markers, particularly among women. These findings indicate a promising and accessible approach to frailty prevention, though randomized controlled trials with longer intervention periods and direct frailty assessments are required to establish effectiveness conclusively.

People have their favorite type of sport, but such preferences tend to be shared for nearly a lifetime. How this preference persists remains inconclusive; hence, this study attempts to determine why people have different viewpoints on sports. It is reasonable to infer that these differences arise from differences in culture, occupation, and race. Therefore, we collected the following data and conducted research in Korea, the United States, and Japan, countries with various differences. The types of sports that people play were collected through surveys and comparisons among sports networks. Namely, “Sport Classification,” “The K-12 Physical Education System (textbooks),” “Survey (actual physical activity),” “Simple Notification Service (SNS) Activity” have been examined to deduce the reason why any particular sport is played. Firstly, Korea, the United States, and Japan conduct different physical education courses. Hence, the results affect people’s preferences. Secondly, what people post on SNS and their actual physical activities are different. Thirdly, the degree of connection between sports-type varied as well. Lastly, sports that serve the purpose of being regarded as hubs among sports-type were common in Korea, the United States, and Japan.

Different studies have examined impression formation regarding shapes. However, few studies have examined whether shapes directly evoke the emotions. An experiment was conducted to investigate characteristics of forms that evoke negative emotions among adolescents and young children. The results indicated that both adolescents and young children had negative emotions regarding circle-aggregate shapes. It might be possible that characteristics of circle-aggregate shapes include signals that developmentally and evolutionally facilitate approach-avoidance behaviors.
