Butternut squash is rich in carotenoids, including beta-carotene, beta-cryptoxanthin, and alpha-carotene, which are plant pigments that give butternut squash its bright orange color. These compounds are provitamin A carotenoids, meaning your body converts them into retinal and retinoic acid — the active forms of vitamin A. Vitamin A is essential for regulating cell growth, eye health, bone health, and immune function. Additionally, butternut squash is rich in vitamin C, a water-soluble nutrient needed for immune function, collagen synthesis, wound healing, and tissue repair. Both vitamins A and C work as antioxidants in your body, protecting your cells from damage caused by unstable molecules called free radicals. Discover news ways of preparing old favourites.
