How does my diet affect my depression?

A poor diet doesn’t cause unipolar major depression, but inadequate nutrition can result in deficiencies of amino acids, fatty acids, vitamins, and minerals that impair your health, upset bodily processes, disturb the function and growth of brain cells, and worsen your depressive symptoms. Being overweight or underweight can cause psychological discomfort in the short term and can truncate your life in the long term.
