Grains are small, hard seeds that come from plants known as grasses. They are a staple food for many cultures around the world and are used to make products like bread, rice, and pasta. Common types of grains include wheat, corn, oats, and barley. Grains are rich in carbohydrates, which provide energy, and they also contain important nutrients like fiber, vitamins, and minerals. When grains are harvested, they can be processed in various ways. Some grains are ground into flour, while others are cooked whole. Whole grains, which include the entire seed, are often considered healthier than refined grains, as they retain more nutrients. Eating a variety of grains can contribute to a balanced diet and overall well-being.
