Whole grains play a crucial role in a nutritious diet due to their high content of fiber, vitamins, and minerals. They help regulate blood sugar levels, reducing the risk of type 2 diabetes and cardiovascular diseases. Whole grains can promote a healthy digestive system by supporting gut health and preventing constipation. Furthermore, their slow release of energy provides lasting satiety, aiding in weight management. Including whole grains like brown rice, quinoa, and whole wheat products ensures a balanced intake of essential nutrients that support overall health.
