For me, food often triggered depression and the easiest treatment has been to change my diet along with seeing a counselor, working a 12 step program, and reading books. A whole plant based food diet for me has led to roughly an 80% reduction in triggering of depression and eliminated the need for any medication also! I only was motivated to try the diet after going into a depression consistently within just minutes of eating meals that were filled with a lot of meat, animal products, and added sugars, oils and salts usually all to great excess together.
