Food staples are basic foods that are commonly consumed and provide a significant portion of a population's energy and nutritional needs. These foods are often inexpensive, widely available, and can be stored for long periods. Examples of food staples include rice, wheat, corn, and potatoes. They form the foundation of many diets around the world. Different regions may have their own specific staples based on local agriculture and climate. For instance, in Asia, rice is a primary staple, while in Europe, bread made from wheat is more common. These staples are essential for food security and play a crucial role in cultural cuisines.
