Common sources of dietary carbohydrates include grains (like rice, bread, and pasta), fruits, vegetables, and legumes. Whole grains provide fiber and essential nutrients, making them a healthier option than refined grains. Fruits and vegetables contribute not only carbohydrates but also vitamins, minerals, and antioxidants, promoting overall health. Legumes, such as beans and lentils, are high in both carbohydrates and protein, making them a nutritious addition to meals. Choosing a variety of carbohydrate sources is essential for balanced nutrition.
