There is an old saying: You are what you eat. When you eat the right foods, you feel better physically. But what you eat can also make you feel better emotionally and mentally. American Leslie Korn is a mental health expert. She has been treating people for trauma and depression for more than 40 years. Korn noticed that some of the foods her patients were eating seemed to affect their mental health. She noted that eating foods like dark chocolate, sweet potatoes, eggs and cherries seemed to lower pain levels and ease signs of depression in the patients. She likens the human body to an automobile a car that needs the right fuel to run.
