When the weather gets cooler, butternut squash often becomes a seasonal favorite—whether in soups, roasted dishes, or cozy casseroles. Beyond its comforting taste, this bright orange winter squash offers a wide range of health benefits. Packed with antioxidants, fiber, and essential nutrients, butternut squash supports several aspects of your well-being.

Here’s a breakdown of the key health benefits of butternut squash, plus its nutritional content, risks, and practical ways to enjoy it.

1. Supports Healthy Vision

Butternut squash is a rich source of vitamin A, primarily in the form of beta-carotene, which gives the squash its vibrant orange hue. Vitamin A is crucial for eye function, helping maintain the health of the retina, cornea, and surrounding eye tissues.

Beta-carotene has been studied for its role in preventing age-related macular degeneration (AMD), a leading cause of vision loss. In addition to vitamin A, butternut squash contains vitamin C and vitamin E, two antioxidants that may help protect eye tissues from oxidative stress and reduce the risk of cataracts and AMD.

While taking supplements alone may not prevent eye diseases, getting these nutrients through food sources—like butternut squash—has been linked to better eye health outcomes.

2. May Lower the Risk of Chronic Diseases and Cancer

As a plant-based food rich in fiber, vitamins, and antioxidants, butternut squash may help lower your risk of chronic health issues.

  • Fiber supports better blood sugar control and cardiovascular health.
  • Antioxidants, including beta-carotene and vitamin C, help protect cells from oxidative damage, a contributor to diseases like heart disease, neurological disorders, and certain cancers.

Research shows that higher dietary intake of beta-carotene is linked with a reduced risk of lung cancer in non-smokers, while vitamin C may lower the risk of both cancer and heart disease. Regularly including antioxidant-rich foods like butternut squash in your diet may provide long-term protective effects.

3. Enhances Skin Health

Butternut squash contributes to healthy skin, thanks to its rich concentration of vitamin C and vitamin E.

  • Vitamin C is essential for producing collagen, the structural protein responsible for skin elasticity and wound healing. Deficiency in vitamin C can lead to fragile skin and gum issues.
  • Vitamin E helps protect the skin from UV damage and may reduce oxidative stress that contributes to acne and other inflammatory skin conditions.

Together, these vitamins support a strong skin barrier, promote healing, and defend against environmental damage. Eating squash regularly may help your skin look and feel healthier over time.

4. Promotes Digestive Wellness

One serving of butternut squash provides about 10% of your daily fiber needs. Fiber plays a key role in keeping your digestive system regular and reducing the risk of constipation.

Beyond regularity, fiber helps feed beneficial gut bacteria, promoting a healthier gut microbiome. A healthy microbiome isn’t just good for digestion—it’s been linked to stronger immunity and improved mental well-being as well.

Adding more fiber-rich foods like butternut squash, whole grains, nuts, and fruits can help you meet daily recommendations and support long-term digestive health.

Potential Risks of Eating Butternut Squash

Butternut squash is generally safe and healthy, but there are a couple of points to consider:

  • Carotenoderma: Eating large quantities of beta-carotene-rich foods can cause a harmless condition called carotenoderma, where the skin takes on a yellow-orange hue. This effect is reversible and not dangerous.
  • Vitamin A toxicity: Unlike beta-carotene from plants, pre-formed vitamin A from animal sources (like liver) can be toxic in large amounts. Butternut squash does not carry this risk.

As long as you consume a varied diet, butternut squash is a safe and beneficial choice.
