There are two basic types of carbohydrates - simple carbohydrates and complex carbohydrates. Simple carbohydrates, also known as monosaccharides, are easy-to-digest carbs that are generally found in fruits, dairy products, processed foods like pastas, and white sugar. On the other hand, complex carbohydrates are difficult to digest and are found in legumes, whole grain breads, brown rice, and vegetables. Complex carbs provide you with energy and are more filling.
