**What are complex carbohydrates, and why are they important?**
Complex carbohydrates, such as whole grains, legumes, and vegetables, consist of longer chains of sugar molecules, providing a steady release of energy. They are important for maintaining blood sugar levels and promoting digestive health due to their high fiber content. Complex carbohydrates provide essential nutrients and are less likely to contribute to weight gain when compared to simple carbohydrates. They also support sustained energy levels, making them a crucial part of a balanced diet for athletes and individuals alike.
