The Impact of Diet on Mental Health

Diet plays a crucial role in mental health, independent of body weight or other factors. Research has shown that a healthy diet can have a positive impact on mental disorders like depression and anxiety. The composition of the gut microbiome, influenced by diet, has been linked to mental and brain health. The diversity of the gut microbiota is considered a marker of gut health and is associated with better health outcomes. Fermented foods, such as kefir and kimchi, can improve gut diversity and reduce inflammation. Additionally, polyphenols found in fruits, vegetables, and herbs have protective effects on brain health. Recent policy changes and clinical guidelines now recognize the importance of lifestyle interventions, including diet, exercise, and sleep, in the treatment of mental disorders. Efforts are being made to train healthcare professionals and implement these interventions in real-world clinical practice.
