Diet quality and anxiety: a critical overview with focus on the gut microbiome

The gut microbiome plays a crucial role in how diet impacts overall health, but the specific interactions between dietary components, gut microbes, and depression risk remain unclear. This study by Samuthpongtorn et al. (2024) aimed to explore these connections using extensive dietary and depression data from a long-term cohort of women (n = 32,427). Additionally, […]
