Diet affects our mental health. Countless research has shown how some foods have short- to long-term positive impacts on the brain and the reduction of stress. It includes fermented foods - such as kimchi or kombucha - which are good sources of tryptophan, an amino acid that is crucial in the production of serotonin responsible for mood. They are staple in many countries and are ingrained in their rich culture and diet.
Over the years, there seems to be a rise in consumption of fermented products and some of them have gone viral in their popularity. It seems that there is more logic offered to fermented foods than just a mere method of preservation.
However, more research and rigorous testing is needed in determining which groups of fermented food had the greatest effects on the human brain and doing it on artificial colon and various animal models to gauge how these metabolites affect the brain. The result encourages individuals to include fermented foods in their diet as a natural way to support their mental health and general well-being.
