Examples of healthy foods with high carbohydrate content include rolled oats, lentil soups, blueberries, low-fat plain yogurt and whole-wheat pasta. Carbohydrates are a necessary part of a diet, providing the body with the energy required to undertake daily activities.
Outside of providing the figurative fuel to energize the body, the consumption of adequate levels of carbohydrates allows protein absorbed by the body to be used for its primary purpose of tissue synthesis. Carbohydrates are also a good source of vitamins and minerals.
Carbohydrates stored in the body are called glycogen. The majority of glycogen storage in a human body occurs in the liver and muscles, although lesser amounts are present in the bloodstream. Muscle glycogen levels affect the duration and intensity of exercise; low levels reduce the time that a person may exercise at maximum capacity.
All carbohydrates are not of equal nutritional value, states Donna Logan, a registered dietitian at the University of Texas Medical School in Houston. The best carbohydrates constitute high levels of fiber, as reported by the U.S. Department of Agriculture's dietary guidelines. Examples of carbohydrates with high fiber content include vegetables, fruits and whole grains. Fiber reduces the risk of heart disease and slows the absorption of glucose in the blood stream.
