Butternut squash contains many different nutrients, such as vitamins A and C, potassium and fiber.

Nutrition Profile

Each cup of cubed butternut squash provides approximately 60 calories, 16 g of carbohydrates and 3 g of fiber. It also supplies almost 300 percent of your daily value of vitamin A, 50 percent of vitamin C, 7 percent of calcium and 5 percent of iron.

Vitamin A

Beta carotene imparts the orange-yellow color of butternut squash. In the body, beta carotene is converted to vitamin A, which helps maintain eye health. Vitamin A, a fat-soluble vitamin, also is important in maintaining healthy mucous membranes and other soft tissues, and it plays a role in promoting healthy skin.

Vitamin C

Butternut squash is an excellent source of vitamin C, which aids in wound healing and is important for gum health. Growth and repair of tissues depends on vitamin C. Cartilage, scar tissue, ligaments and blood vessels depend on vitamin C for development. Another function of vitamin C is increasing the body's absorption of iron.


The potassium in butternut squash helps maintain healthy blood pressure. Potassium is a mineral that also promotes normal body growth and protein synthesis for muscle development.
