A healthy eating plan that helps you manage your recovery includes a variety of foods you may not have considered. Focus on foods that will increase the dopamine in your brain. Studies show that increasing the amount of protein in the diet can increase dopamine levels in the brain, which may promote deep thinking and improve memory. Some research has found that saturated fats may disrupt dopamine signaling in the brain when consumed in very large quantities. Foods like dark, leafy greens, oranges, and tomatoes—even fresh herbs—are loaded with vitamins, fiber, and minerals.
