Squash Varieties Offer Diverse Nutritional Benefits, Dietitian Says

Winter squashes, often overshadowed by butternut and pumpkin, offer a surprising array of nutritional benefits, including fiber, vitamins, and antioxidants that can support digestion and immune health. Registered dietitian Johannah Katz highlights six favorite varieties, detailing their unique advantages.

Delicata squash is noted for its ease of preparation, featuring thin, edible skin that requires no peeling, reducing prep time and food waste. It also provides fiber and potassium, beneficial for digestion and muscle function.

Spaghetti squash serves as a lower-carbohydrate alternative to traditional pasta. One cup of cooked spaghetti squash contains approximately 42 calories and 10 grams of carbohydrates, compared to about 200 calories and over 40 grams of carbs in the same amount of pasta. Katz suggests pairing it with lean proteins to create a more balanced meal.

Kabocha squash, also known as Japanese pumpkin, boasts a dense, creamy texture and a sweet flavor. Its notable carotenoid content, including beta-carotene, lutein, and zeaxanthin, supports eye health. The skin of kabocha squash also softens when cooked and can be consumed.

Pumpkin, a familiar staple, is rich in beta-carotene, which the body converts to vitamin A. This vitamin is crucial for vision, immune function, and skin health, and it helps maintain protective barriers in the respiratory and digestive tracts, offering a defense against winter illnesses. Canned pumpkin is highlighted as an affordable and versatile option, readily usable in various sweet and savory dishes.

Butternut squash is particularly abundant in beta-carotene and vitamin C. One cup of baked butternut squash contains about 82 calories, nearly 7 grams of fiber, and provides approximately 34% of the daily recommended value for vitamin C. This combination supports immune function and reduces inflammation.

Acorn squash tops the list for its high fiber and potassium content, essential for digestive and heart health. One cup of baked acorn squash offers about 9 grams of fiber and nearly 900 milligrams of potassium, significantly contributing to daily intake recommendations. It also provides magnesium and vitamin B6.

Katz advises that the healthiest squash depends on individual nutritional goals and preferences. While acorn squash excels in fiber and potassium, butternut squash is a strong source of vitamin A. Kabocha offers carotenoids, and canned pumpkin provides a convenient and economical dose of beta-carotene. Spaghetti squash is recommended for those seeking lower-carbohydrate options, and delicata for its simple preparation.

For individuals managing kidney disease who need to limit potassium intake, caution is advised regarding portion sizes of certain squash varieties. Katz emphasizes that diversifying winter squash consumption allows for a broader intake of nutrients, flavors, and textures, making healthy eating more engaging.
