Winter squash (Australia: pumpkin) is a warm-seasoned vegetable, representing several species within the genus Cucurbita. It differs from summer squash in that it is harvested and eaten in the mature fruit stage, when the seeds within have matured fully and the skin has hardened into a tough rind. At this stage, most varieties of this fruit can be stored for use during the winter. It is generally cooked before eating.
Winter squash is a good source of complex carbohydrates such as starch, and also fibre. It is also a source of niacin, potassium, iron and beta carotene. Usually, the darker the skin is, the higher the beta carotene content.
