Include ripe bananas as part of your daily diet. As a banana matures, it produces dopamine quinine, a naturally occurring form of dopamine. Although small brown areas on the fruit indicate bruising, these portions also contain the highest levels of dopamine. Supplement your diet with foods rich in antioxidants. Free radicals lower dopamine levels in the body, and antioxidants eliminate free radicals. Most vegetables and fruits contain some antioxidants, with red beans, blueberries, cranberries, artichokes, prunes and strawberries topping the list. Reduce your intake of sugary foods and saturated fats.
