Acorn squash is one of the winter squashes, which in temperate climates are harvested in the autumn when their seeds have matured and their outer skins have hardened into a rind. They’re called “winter” squashes because, before refrigeration, they could be kept and eaten through the winter.
As you might guess from the acorn squash’s orange flesh, it is a good source of antioxidant carotenes. It also provides the minerals magnesium, manganese, potassium, and calcium, and vitamins A and C.Nutritional Facts
