Yam tubers can grow up to 2.5 meters in length and weigh up to 70 kg (150 pounds). The majority of the vegetable is composed of a much softer substance known as the "meat". This substance ranges in color from white to bright orange in ripe yams.
Yams are a primary agricultural commodity in West Africa and New Guinea. They were first cultivated in Africa and Asia about 8000 B.C. Yams are important to this day for survival in these regions. The tubers can be stored up to six months without refrigeration, which makes them a valuable resource for the yearly period of food scarcity at the beginning of the wet season.
