What are complex carbohydrates?
Carbohydrates are found in every plant food and should make up a large portion of any healthy diet. They are the most easily metabolized source of energy for the body and allow the protein and fat that you eat to be used for building and renewing cells rather than used up for energy. Complex carbohydrates are typically unrefined plant foods such as whole grains, legumes, vegetables and fruit. A good way to assess the suitability of carbohydrate choices is to look at the amount of fiber on the nutrient facts panelsimple carbohydrates in foods such as refined breads and pastas, pastries, candies and soda have very little fiber per serving.
