What role does carbohydrate intake play in modulating the gut-brain axis and its effects on mood and cognition?

Carbohydrate intake plays a role in modulating the gut-brain axis by influencing gut microbiota and neurotransmitter production, which can affect mood and cognition. Carbohydrates, particularly those high in fiber, support a healthy gut microbiome, which in turn affects brain function and mental health. The gut-brain axis connects gut health to cognitive and emotional well-being, making balanced carbohydrate consumption important for maintaining optimal mood and cognitive function.
