The relationship between the gut microbiome and neurodegenerative diseases
This 2021 study focuses on the association between the gut microbiome and neurodegenerative diseases. The microbiome living in our guts play important roles in human physiology and pathology, which has led to microbiome-based approaches for enhancing health and treating diseases. Researchers have tried to determine the relationship between gut microbiome and neurodegenerative and aging diseases (such as Alzheimer’s, Parkinson’s disease) but the exact interactions between these two remain unclear. Hopefully, the interrelations will be confirmed as technology advances and new study techniques will be developed. This article presents the currently known aspects of the connection between gut microbiome and neurodegenerative diseases. For instance, the author discusses the potential therapeutic role of microbiome-based therapies in diseases.

This 2022 review compared the differences in gut microbiota composition between healthy individuals and patients diagnosed with major psychiatric disorders, major depressive disorder (MDD), bipolar disorder (BD) and schizophrenia (SZ). In addition, McGuinness et al. looked at potential commonalities in bacterial characteristics between sufferers of mental health disorders. After conducting a number of database searches, […]
Fermented foods are often associated with positive health effects, particularly through their impact on gut microbiota; however, current research supporting these claims remains limited. This study by Pihelgas et al. (2025) investigated the health impacts of eating fermented vegetables (FVs)—specifically fermented carrots, kohlrabi, and kimchi—by examining changes in gut microbiota and other health-related measures. Researchers […]
