The old adage "you are what you eat" holds some truth. Food is fuel for the body and the right foods can help fight fatigue and give you additional energy for the day's tasks. Avoiding simple carbohydrates -- those made of white flour and sugar -- is a good start, as these foods provide a rapid spike in blood sugar that leads to a sudden crash. Better choices include iron-rich foods, complex carbohydrates and foods that are high in fiber. These foods not only increase energy, they can also promote weight loss and improve overall health.
Iron-Rich Foods
Iron deficiency is the most common nutritional deficiency, according to the Centers for Disease Control and Prevention. The essential mineral, iron, is responsible for carrying oxygen from the lungs throughout the body. A deficiency in iron can lead to anemia -- a condition that causes chronic fatigue. Foods rich in iron include dark leafy greens, iron fortified cereals, beef, dried fruits and beans.
Complex Carbohydrates
Carbohydrates are the body's best source of immediate energy and according to Kidshealth, they are an essential part of a healthy diet for children and adults. Complex carbohydrates provide both immediate and sustainable energy as they are slowly broken down into simple sugars, which allow the blood sugar to rise gradually rather than causing rapid increases that eventually lead to a drop in both blood sugar and energy. Whole grain foods such as whole wheat breads, pasta, brown rice and oatmeal are a good source of complex carbohydrates.
High Fiber Foods
High fiber foods move slowly through the digestive system, and therefore keep you fuller and more energetic for longer. Fruits and vegetables are a satiated source of fiber, and can be consumed on the go in whole or liquid form. Fruit and vegetable juices, whole apples, raisins, chopped carrots, celery or broccoli are some high-fiber options. Additional benefits to eating high-fiber foods are weight loss and reduced risks of constipation and chronic diseases, according to HelpGuide.org.
