Winter squash — in all kinds of shapes, sizes and gorgeous colors — take over produce aisles when the temperature drops, leaves change color, woodpiles grow and comfort foods replace summer salads. It must be autumn.
Varieties of winter squash include butternut, acorn, hubbard and turban squash, as well as pumpkin. All winter squash have tough skin that is more difficult to pierce than that of its cousins, the cucumber and melon. The hard shells provide a longer shelf life — sometimes as long as six months.

Winter squash offer a variety of health benefits. They are good sources of vitamins A, C, B5 and B6, potassium and manganese, as well as dietary fiber. They provide folate, copper, niacin and thiamin. They also have beneficial omega-3 fatty acids.
Research is still forthcoming, but early results show that winter squash contain anti-cancer and anti-inflammatory properties and help relieve symptoms of benign prostatic hypertrophy (BPH). Consuming winter squash may also lower the risk of developing lung cancer, according to a Kansas State University study.
Winter squash can be added to the typical comfort foods of the colder months. Pumpkin bread straight from the oven warms the heart, as well as the tummy. Spaghetti squash is delicious with fresh pasta sauce and grated Parmigiano-Reggiano cheese. And cubed acorn squash adds a subtle sweetness to soups.
