Staple crops are plants grown for their parts which are used as staple food. A staple food is one that is regularly consumed in large quantities as to form the basis of a traditional diet and which serves as a major source of energy and nutrients.
Staples may be grouped into the starchy type and protein-rich type. The starchy type consists of the cereal crops, root and tuber crops, fruit crops and the palms. The pulses belong to the protein-rich group. Many traditional diets in developing countries consist of both starchy and legume staples to obtain a more nourishing food.
Botanically, the plant part that is consumed may be a seed, fruit, modified root, modified stem, or pith of the stem (as in sago palm). Many cereals, roots and tuber crops are staple crops but are also grown extensively for processing into industrial products such as vegetable oil and biofuel.
Although more than 50,000 plants in the world are edible, only a few hundred are consumed in significant amounts. Ninety percent of the world’s food energy intake comes from a mere 15 crops with rice, corn and wheat contributing two-thirds of this. These three are the staples of more than 4,000 million people, with rice being consumed by almost one-half of the world population.
