Abstract
Background: Gut health gained significant attention in recent years, with prebiotics and probiotics widely promoted for their potential health benefits. However, misinformation about this topic was common, particularly among young adults who were heavily influenced by social media and advertising on health-related topics. Research studies had indicated that knowledge and perceptions of prebiotics and probiotics are based on factors such as age, gender, and academic background. This study aimed to assess the knowledge and perceptions of university students on prebiotic and probiotic foods, identify commonly used resources for information, and analyze the impact of media and demographic variables on their knowledge, attitudes, and dietary behaviors.
Methods: A cross-sectional study was conducted using an anonymous online survey distributed to university students attending two California State University campuses in Southern California. Participants were recruited through campus wide email notifications and announcements by instructor of courses on campus. The survey assessed students’ familiarity with prebiotics and probiotics, dietary habits, perceived health benefits, and sources of information.
Results: The findings provided insight into the factors that influenced students’ understanding of prebiotics and probiotics, highlighting areas where targeted educational efforts could improve awareness and promote informed dietary choices for a better gut microbiome.
