Grain and cereal preparations are essential components of diets worldwide, providing a rich source of carbohydrates, fiber, vitamins, and minerals. From staple grains like rice, wheat, and corn to ancient varieties such as quinoa, barley, and millet, these foods are versatile and nutritious. Common preparations include cooking grains as a side dish, using them in salads, or incorporating them into baked goods like bread and muffins. Cereals, often enjoyed at breakfast, can be served as hot porridge or cold with milk or yogurt, and can be flavored with fruits, nuts, and spices. With their ability to be both hearty and healthful, grain and cereal preparations play a crucial role in promoting balanced diets and culinary diversity across cultures.
