This document discusses how depression can be lifted through nutrition and exercise without medication. It outlines various signs of depression and potential causes such as life stress, nutritional deficiencies, and hormonal imbalances. Low serotonin levels are linked to depression, and certain foods like sugar can cause serotonin crashes and cravings that worsen symptoms. Supplementing nutrients that support neurotransmitters like vitamins, minerals, amino acids and essential fatty acids can help lift depression. Lifestyle habits like a whole foods diet, exercise, sleep, and stress management are also recommended beyond supplementation alone.
