The gut produces 90% of body's serotonin. Research shows gut microbiome affects mood, anxiety, and cognition. Fiber-rich diet, fermented foods, and polyphenols support mental health through gut health.

My anxiety improved significantly after adding kimchi and sauerkraut to my diet.

The brain-gut axis is fascinating. What we eat literally affects how we think and feel.

I take a probiotic and eat more prebiotic foods (onions, garlic, bananas). Mood is noticeably better.
