Enriched complex carbohydrates are the preferred food for both the brain and body. They serve as a form of energy storage in plants. When you eat food from those plants, your body breaks down the carbohydrates to meet your own energy needs. About half the calories in your diet should come from complex carbohydrates. The best complex carbohydrates come from legumes, vegetables and 100% whole grain bread, cereal and pasta products. These contain fiber and a variety of nutrients that refined flour has lost.
