What are staples use for in the food pyramid?

In the food pyramid, staples refer to the foundational foods that form the base of a healthy diet, primarily including grains like rice, wheat, and corn. These foods provide essential carbohydrates, which are a key source of energy for the body. Staples are typically consumed in larger quantities and are often complemented by other food groups, such as fruits, vegetables, proteins, and dairy, to ensure a balanced diet. Their role is crucial for sustaining daily energy levels and overall nutritional health.
