Complex carbohydrates are a type of carbohydrate made up of long chains of sugar molecules. They are found in foods like whole grains, legumes, and vegetables. Unlike simple carbohydrates, which provide quick energy, complex carbohydrates are digested more slowly, offering a steady source of energy over time. This makes them an important part of a balanced diet. These carbohydrates also contain essential nutrients and fiber, which can aid in digestion and help maintain a healthy weight. Foods rich in complex carbohydrates, such as brown rice, quinoa, and sweet potatoes, can contribute to overall health and well-being by providing sustained energy and important vitamins and minerals.
