Squash, butternut, raw

Butternut squash is a vegetable, and the nutritional values here refer to it raw. It provides carbohydrate, vitamins and minerals, with little fat or protein. Per 100g, it contains 8.3g of carbohydrate, 0.1g of fat, 605µg of vitamin A expressed as retinol equivalent, and 21mg of vitamin C.

The vitamin A value reflects carotenoids that the body can convert to vitamin A, which supports normal vision and immune function. Vitamin C helps with collagen formation and the absorption of iron from plant foods. Raw butternut squash is low in salt, although added salt during preparation changes this.
